What are the main uses of Mechanical stamping?

Mechanical stamping is a metal stamping and forming machine that uses preformed dies and pressure to form sheet metal blanks into products and parts. The manufacturer uses an automatic or manual feeder to insert the sheet metal into the stamping press between the tool and the die surface. The press descends onto the sheet metal and uses compressive forces to press the material into the die to form the desired shape.

How does Mechanical stamping work?

Metal can be shaped or cut precisely to your specifications. The process involves forming, stretching, trimming, punching and/or perforating the metal with a die. Typically, the process is available in sheet metal and coil form.

The press consists of a pad and a plunger. The stamping process works by forming the metal between the two halves of the stamping tool. The top part is attached to the slide of the press, while the bottom part is attached to a fixed pad (or bed). Some large presses also have a die pad integrated into the pad plate that helps apply the crimping force

What types of Mechanical stamping are available?

Mechanical stamping press is generally distinguished by the body structure type and application characteristics.

According to the body structure type: there are open and closed two types.

• Open type press

  Open type presses are mostly vertical. The body is C-shaped, the front, left and right side open, simple structure, easy to operate, The body is C-shaped, the front, left and right side open, simple structure, easy to operate, the body can be tilted to a certain angle, so that the workpiece slides down into the hopper, easy to achieve automation, But the open body rigidity is poor, affecting the accuracy of the parts and die life, only for 40 ~ kN of small and medium-sized presses.

• Closed type press

  The body is H-shaped, the front and rear of the body open, good rigidity, high precision, the size of the table is larger, suitable for pressing large parts, The body is H-shaped, the front and rear of the body open, good rigidity, high precision, the size of the table is larger, suitable for pressing large parts, nominal working force of ~ kN. cold extrusion, hot die forging and double-action deep drawing and other heavy presses use closed body.

  According to the application characteristics: there are double-action deep drawing press, multi-station automatic press, rotary head press, hot die forging press and cold extrusion press.

Why is Mechanical stamping worth the investment?

Mechanical stamping offers high production speeds and allows for mass production. On Mechanical stamping, only a few standard parameters can be set, so the machine is not as flexible or versatile as a hydraulic press. Mechanical stamping usually requires an operator to manage the operations associated with the strikes. Therefore, it is necessary to equip such machines with suitable safety devices, such as foot switches, grills, etc.

MachineMechanical stamping are usually high precision machines and can guarantee repeated strikes over time. On the other hand, they run only on a given course. Therefore, it is important to check that the opening distances are appropriate for the part size before and after manufacturing.

MachineMechanical stamping makes forming metal materials easier and more efficient. Understanding the different types and how they work will allow you to choose the one that best suits your business.

What are the common stamping materials for Mechanical stamping?

Mechanical stamping machines can stamp and form a variety of metals, including ferrous and non-ferrous metals. Typically the type of metal chosen for a metal stamping part depends greatly on its intended application as well as the size, shape and design of the product.

• Ferrous Metals

  Ferrous metals containing iron are usually magnetic and tend to be strong and durable. Steel is a well known ferrous metal with a wide range of uses. Ferrous metals are valued for their high strength, but their iron content makes them more susceptible to rust and corrosion than non-ferrous metals. Carbon steel is the most commonly used ferrous metal in metal stamping applications because of its extremely high tensile strength. 

• Non-Ferrous Metals

  Non-ferrous metals and alloys do not include iron and are therefore not magnetic. Non-ferrous metals are very popular in a variety of stamping products because of their high ductility and wide range of useful properties. The most common non-ferrous metals used in stamping applications include aluminum, tin, copper, brass, bronze, gold and silver. Aluminum is particularly popular in stamped parts and products due to its low cost, lightweight strength and corrosion resistance. 

  When selecting the right material for your metal stamping application, it is also important to consider the material composition of the tooling you will be using. While most dies consist of tool or hardened steel, different workpiece materials or processes may require alternative die materials, such as aluminum or mild steel. 

Why source Mechanical stamping from China?

Many Chinese Mechanical stamping manufacturers combine American, European and domestic technologies with Chinese manufacturing advantages.

This alone gives Chinese companies the upper hand over all of their global competitors. As a result, most Chinese Mechanical stamping is cost competitive with American and European made machines.

You will find that most European and American companies have OEM partners in China. Nevertheless, using this business model, you will pay more for Mechanical stamping.

In short, it is cost effective to source Mechanical stamping from China. Always strive for the best deal.

What are the factors to consider when buying Mechanical stamping?

• Know your needs

  Before you start browsing and selecting a Mechanical stamping machine, write down a general list of the jobs you regularly perform. Whether it's drop stock, stamping, punching, bending, deep drawing, metal forming or molding, know how you will use your new press.

  This will tell you which processes you need the machine Mechanical stamping to perform.

• Flexibility of choice

  Modern presses for mechanical stamping have a wide range of tonnage and many features. Many make it easy to control pressure and plunger speed. These presses are highly customizable and can easily handle a variety of jobs. Use a full-featured press that can handle many types of jobs from the master list of processes you often need to complete.

• Using advanced technology

  The latest mechanical presses can handle more complex jobs faster and more efficiently than previous presses. They are equipped with programmable electronic control panels. This means you can customize your press features to individual jobs and their specifications. You get a consistently high level of output excellence at a faster rate.

• Check accuracy and precision

  Most machine shops need to deliver high-end results for their customers. That's why it's critical to choose a machine press that offers precision and accuracy for every job. Choose a model with an adjustable power function and lateral movement slide control. This can prevent problems with unbalanced loads.

• Choose a versatile design

  Choose technology that allows your operators to take full advantage of the press, using its design and production techniques creatively. If you need low tonnage, use a larger press. Smaller bed presses can handle high tonnage and high quality finishes, using side action, under action and multi-action.

• Research cost effectiveness

  Modern machineMechanical stamping saves space and minimizes maintenance costs. They take up less than half the space of machineMechanical stamping. This means you can make efficient use of store space. Ensure that spare parts for the press you are working on are easy to find, thus limiting potential downtime.

What are the main technical specifications of Mechanical stamping?

It is important to know how the starting tonnage is calculated in order to choose the most suitable mechanical stamping press.

The calculation formula is as follows.

P= p/q= (64-73) F/q where P---- screw press tonnage (KN)

p - the deformation force required for die forging (KN)

F - forging together with the projected area of the flying edge (cm 2)

(64 to 73) - the coefficient is taken as 73 for complex forgings and 64 for simple parts.

q - is a deformation coefficient, which can be divided by stroke and deformation work in spiral press die forging.

Forgings require a larger deformation stroke, deformation and deformation work in die forging, q = 0.9 to 1.1.

When forgings need smaller deformation stroke and deformation work of die forging q=1.3.

When the forgings need only a small deformation stroke, but need a large deformation force for fine pressing q=1.6.

P=(17.5~28)KF total (KN) where the total projected area of forging together with flying edge (㎝2)

K - steel grade coefficient, refer to the third unit of the equipment tonnage calculation chapter; ((17.5-28) - coefficient 28 is used for difficult deformation (such as extrusion deformation, deformation with flying edges, etc.) and high productivity, and vice versa. The above formula applies to the calculation of the required equipment tonnage hammering 2-3 times.

If a single stamping is required, it should be doubled as calculated.

What is the best way to maintain Mechanical stamping?

Mechanical stamping machines should be maintained in a standard way during daily use. There is no doubt that normal and reasonable maintenance can greatly save production costs for later maintenance and bring greater cost benefits.

• Before each shift, operate the brake shaft of the manipulator with full lubricating oil at each point, and lubricate the clutch part with oil pressure once a day. Clean the machine before stopping each shift.

• Inspect all aspects of the mechanical press. Check fasteners and make up missing external parts; check the clutch, springs and belts; check the lubrication device of the machine; check the damage and aging of the circuit and the normalcy of the motor and solenoid; check the accuracy and wear of the crankshaft guide; check the brake, clutch, slider, closing block and closing ring; check the electrical control part; check and adjust the body table connecting bolts.

• According to the different types of presses and processing requirements, develop targeted and practical safety operating procedures, and conduct the necessary job training and safety education. Using units and operators must strictly comply with the design and manufacturing units, provide safety instructions and operating procedures, and use and maintain them correctly.

• Pay attention to safety during maintenance to ensure that the locking and opening process is performed correctly to ensure the safety of maintenance personnel and that the sleeve is placed at the bottom of the stroke before performing maintenance work on the brake. If this is done, the sleeve does not need to be locked.

• Shop floor environmental controls. A clean press allows the operator or maintenance personnel to identify problems as soon as they occur. For example, if the press is clean, it is easy to identify the location of oil leaks, air leaks, breaks, etc.

• Make sure the mechanical press is in a balanced position. A precisely balanced press will work better, so it is best to check it once a year. Pneumatic systems that operate pneumatic braking and balancing systems need to be checked for air leaks, as improper air pressure can affect the performance of the braking and balancing systems and they control the stopping time of the press, which can put the operator and the equipment at risk if there is a problem. In addition, all pneumatic systems have regulators, lubricators and water reservoirs. Water that accumulates in the gas lines should be removed daily.

• Replace lubricants and screens regularly. Improper maintenance of the press lubrication system is also a major cause of press downtime. For a variety of reasons, many press operators operate screen-equipped circulating oil systems without changing screens regularly. Be sure to change the screen at the same time as the oil change and generally change it frequently.

So back to the question before, what is stamping automation?
Stamping automation refers to the integration of automated systems, such as robotics and control mechanisms, into the metal stamping process to enhance efficiency, reduce human labor, and improve product consistency. The following sections will explore key components, advantages, and considerations surrounding stamping automation in modern manufacturing.

Key Components of Stamping Automation

Stamping automation involves several interconnected systems that work together to complete the stamping process with minimal human intervention. These systems include robot arms, automatic transfer systems, die change systems, and quality inspection equipment. The role of these automated systems is to handle material loading, unloading, positioning, and stamping operations efficiently.

• Robotic Arms in Stamping
  One of the most common and essential components in stamping automation is the robotic arm, also known as a manipulator. These arms are designed to perform tasks like handling, loading, and unloading metal sheets or parts within the stamping line. Robotic arms can move in 2D or 3D, depending on the complexity of the task, and they are capable of performing repetitive and precise movements that improve production speed and safety.

A significant advantage of robotic arms is their ability to work in dangerous environments where human operators would face safety risks. For instance, in high-beat stamping lines where large volumes of parts are produced, a robotic arm can operate continuously without fatigue, maintaining consistent performance throughout the production cycle. The development of various types of robotic arms, including the independent manipulator and in-mold manipulator, has made it possible for manufacturers to select the right solution based on their specific process requirements.

• Automatic Transfer Systems
  An automated transfer system is another vital part of stamping automation. It transfers metal parts or sheets from one stage of the stamping process to another without manual handling. This system ensures smooth, continuous movement across multiple stations, reducing downtime and increasing production efficiency. By eliminating human involvement in material transfer, automated systems also help minimize errors and potential damage to parts during handling.

In high-volume production lines, automatic transfer systems help maintain a constant flow, reducing bottlenecks and increasing output. These systems are particularly useful in industries that require precision, such as automotive and electronics manufacturing. With the integration of advanced sensors and control technologies, transfer systems can adjust speed, position, and alignment to meet the demands of different stamping operations.

• Die Change Systems
  Stamping processes often require different dies to produce various parts, and traditional manual die changes can be time-consuming and prone to errors. Automation of the die change process has been a game-changer for manufacturers. Automated die change systems allow for quick and accurate changes without interrupting production. These systems can handle dies of different sizes and weights, making it possible to switch between jobs with minimal downtime.

The implementation of automated die change systems has significantly reduced setup times in stamping lines, allowing manufacturers to achieve greater flexibility in production. This is particularly beneficial in industries where multiple product variations are required, such as the automotive sector, where different car parts must be stamped efficiently within tight production schedules.

• Quality Control in Automated Stamping
  Automated stamping systems also integrate advanced inspection equipment to ensure that each part meets quality standards. Quality control systems in stamping automation typically use cameras, sensors, and other detection technologies to monitor the stamping process in real time. These systems can detect defects, misalignments, or deviations from the desired specifications and immediately halt production or make adjustments.

In automated stamping, maintaining consistent quality is essential, especially in industries that rely on high-precision parts. By implementing automatic inspection equipment, manufacturers can reduce the occurrence of defects and ensure that every part produced meets the required tolerances.

• High Production Efficiency
  The primary goal of stamping automation is to increase production efficiency while reducing operational costs. Automated systems, such as robotic arms and transfer systems, work together to complete tasks faster than human operators could. By automating labor-intensive processes, manufacturers can achieve higher output levels without compromising on quality.

Another critical aspect of increasing efficiency is the ability of automated systems to operate 24/7 without the need for breaks, shifts, or downtime. This allows manufacturers to maximize production time and minimize disruptions. Additionally, the use of predictive maintenance systems in stamping automation ensures that machines are serviced before failures occur, further reducing downtime and increasing productivity.
