Custom Stamping Die
Custom stamping dies meet the requirements of workpiece and production efficiency during manufacturing in order to achieve high-quality performance. Customized stamping molds play a crucial role in shaping and transforming raw materials into complex functional components.
Stamping Die Design in Argentina
Stamping die design consists of many steps. Stamping mold is a type of mold used for Argentina stamping processing, mainly composed of convex mold, concave mold, pressing plate, fixing plate, etc. The main raw material of the mold is sheet metal, and the metal stamping die is developed according to the requirements of the stamped parts. A reasonable process plan and mold structure and size are designed to process the sheet metal into a tool for stamping parts.
Custom Stamping die was initially mainly applied to workpieces with simple steps, including cold heading, cutting, shaping, etc. Due to the rapid development of modern manufacturing technology, the precision requirements for stamping dies are also increasing, and the shape and structure are becoming more complex. Therefore, a more efficient design should be implemented for the stamping die to make them more widely used. With the widespread application of the stamping die in the manufacturing industry, they are mainly used in multiple fields such as automobiles, household appliances, and aerospace.
In daily life, some commonly used components will use stamping die, such as car bodies, refrigerators, instruments, brackets, reinforcements, interior parts, etc. Due to the development of modern technology, it is required to manufacture more and more products and various types of products. Operators also need to have good quality requirements for the manufacturing of the stamping die, and product production technology will also improve accordingly.
Requirements for Stamping Die Design
The most important technical preparation work in the Argentina stamping production process is the process and design of the mold. To reduce the cost of stamping die and achieve high-quality production, attention should be paid to the following important requirements. Stamped parts have high requirements for process and quality control, as well as for the design of stamping die.
Operators should have a familiar understanding and mastery of raw materials, stamping machines, design, and processes. To ensure that the manufacturing of stamping die can meet the requirements of various technologies, it is necessary to use reasonable, reliable, and technologically advanced design solutions.
To facilitate standardized use, operators write corresponding process design and Stamping die design content according to the production needs of each product, for the convenience of future operations.
- Process Analysis
The performance of the workpiece and stamping die meets the requirements of the required product, and a detailed analysis of the shape, size, accuracy, and raw materials of the stamping die is required. The size and accuracy requirements of the parts will determine the selection of stamping equipment and the manufacturing accuracy of the molds.
It is also necessary to comprehensively consider the specifications, process level, processing equipment conditions, and other actual situations of the selected stamping machine, which helps to design a stamping die with simple structure and economic applicability. This can ensure that the manufactured workpiece meets the required graphics and size requirements, and has a long service life and high-quality product.
- Design Process Plan
When the Argentina-designed stamping die meets the shape and size of the product, multiple possible stamping die design schemes are proposed based on the actual situation, aiming to solve the process difficulties as much as possible. Try to achieve simple operation, long service life, solid quality of manufactured components, safety performance, and low-cost advantages.
The combination of composite stamping processes or continuous stamping processes should be determined based on the production batch and requirements of the product. According to the characteristics and size of each workpiece, the correct sequence of processes should be determined.
- Overall stamping Die Design
Each type of stamping die may not necessarily use the same stamping process plan, and the same stamping die will have multiple stamping process plans. There are many types of stamping die, and there are also many structural forms and design methods. The operator should consider the production efficiency, difficulty of the manufacturing process, and quality of the workpiece to create a suitable solution.
So it is essential to be proficient in the use of each component, which has greatly helped in the design of stamping die. The structural characteristics of different workpieces will also vary. Each type of mold has many uses, so the structure will also be different. Each stamping die should be designed according to the requirements of use.
The key indicators of the design scheme reference data for process parameters mainly include tensile coefficient, bulging coefficient, part unfolding size, etc. It played an important role in formulating the plan. Calculate the dimensions to ensure that the layout and drawing are correct, and then calculate how much material is used. Approximately calculating the punching force, such as punching force, bending force, drawing force, forming force, complex part blank unfolding size, etc., helps to determine the press machine.
Calculate and ensure the dimensions of the main components of the stamping die, as well as the size and height of the components. The parts that are punched and formed must meet the standard requirements. Choosing the correct positioning component, for progressive molds, attention should be paid to whether to choose material blocking pins, side edges, etc.
- Application of Stamping Equipment
Based on the nature of the Argentina stamping process to be implemented by the current stamping equipment, and the main factors such as the deformation force, deformation work, mold closure height, and contour size required for stamping processing, the type and tonnage of the equipment should be reasonably selected according to the situation of the stamping equipment.
The main requirements of a press include: the slider stroke of the press must meet the requirements of the manufactured product; The nominal pressure of the press must be greater than the punching pressure; The size of the lower mold seat of the mold should be smaller than the size of the working table of the press. The main stamping equipment commonly used is crank press, and commonly used stamping equipment includes crank press, hydraulic press, etc.
Stamping Die Design Process
Every stamping die has a complete process, and the process and design of stamping dies are closely related and affect each other. The design of the stamping die mainly includes three parts, such as the selection and design of stamping die structural forms, calculation of mold structural parameters, and drawing of mold drawings.
The designed mold structure should meet the requirements of the product, pay attention to the shape, size, precision, and other aspects of the components, and the structure of the components should be easy for operators to operate and not dangerous.
Analyze stamping die design: The staff needs to analyze the workpiece, such as its shape, size, material, surface quality, and other requirements before they can start designing stamping dies. Moreover, it is necessary to proficiently master the process technology and production guidelines of stamping parts, providing a basis for the subsequent process design scheme and mold design.
Design stamping die process plan: On the premise of meeting product requirements, it is necessary to develop a reasonable process plan, including process steps, layout methods, feeding direction, and other aspects. The production efficiency of stamping die design is closely related to the process plan.
Structure of stamping die design: After completing the process plan, the operator needs to design the structure of the mold. There are many things to pay attention to in the design of mold structures, mainly including the shape and size of convex and concave molds, pressing plates, and fixing plates. Then, the orientation, positioning, and fixing methods of the mold also play important factors.
Check the strength of the stamping die: After designing the mold structure, checking the stamping mold helps to ensure that the mold will not deform or be damaged due to insufficient strength during use. The commonly used verification method is stress analysis. After checking the strength of the mold, it is necessary to design the mold drawings.
The Forming Process of Stamping Die
Forming refers to the method of using different local deformations to process and manufacture different shapes. The main forming processes include expanding, shaping, flipping, and flanging.
Flipping Edge
The flanging process has many advantages, mainly the ability to process workpieces with complex shapes and good hardness. In the manufacturing process, the flanging process can be widely used to replace bottomless deep drawing parts and the process of drawing and then cutting the bottom. This process helps to improve productivity, reduce material waste, and save time. Because when flipping, the outer edge of the workpiece only needs to be flipped into the desired shape, which saves materials, it is generally used in the production of small batch products.
The common types of flanges are concave flanges and convex flanges. The degree of deformation of the flange: The deformation of the outer convex flange does not require shallow drawing by the edge pressing ring. During the deformation process, the material is prone to wrinkling due to external convex flanging. That is because the material in the deformation zone is subjected to tangential compressive stress. However, the material in the deformation zone is subjected to tangential compressive stress due to concave flanging. Both sides will become thin and fragile, so this part is the most dangerous. If this position is excessively deformed, it may cause fracture.
