Technical Field

[0002] Stamping dies are important process equipment widely used in modern industrial production. With the development of industry and the advancement of technology, the requirements for the precision, quality, and production efficiency of parts are constantly increasing. The emergence and development of stamping dies meet the needs of large-scale, high-efficiency, and high-precision production of metal products. In traditional manufacturing, manual processing is inefficient and difficult to ensure consistency. Stamping dies use equipment such as presses to make materials such as metal sheets plastically deform in an instant through the specific shape and structure of the die, so as to quickly obtain parts of the required shape and size. It has the advantages of high production efficiency, stable product quality, and relatively low cost. At the same time, the range of material selection is wide, ranging from ordinary steel to various alloy materials. In recent years, with the integration of computer technology, CNC technology, etc., the design and manufacturing technology of stamping dies have been continuously innovated and improved, which can realize the processing of more complex shapes, and the precision and reliability are further improved, playing a vital role in many fields such as automobile manufacturing, electronic equipment, and aerospace.

[0003] During the stamping process, the speed is very fast and a lot of vibration will be generated. The raw material can be easily offset from the effective position by the vibration. The product will move relative to the die base with the impact, causing the punched shape to deviate from the expected shape. The effective position of the raw material cannot be guaranteed for a long time, and it is easy to be offset and lead to scrapping. The accuracy is relatively low, so the product needs to be fixed to avoid displacement during the stamping process. Summary of the invention

The supporting rods and the connecting plates are alternately arranged with the punch as the center. The end of the supporting rod away from the fixing plate is rotatably connected to a pressing wheel. During the stamping process, the thin iron plate to be stamped is placed on the support block. At this time, the guide sleeve slides downward on the outer wall of the guide column, so that the top plate drives the fixing plate downward. The top plate continues to move downward, so that the two support rods drive the pressure wheels to rotate toward the opposite sides of the support rods, and then the pressure wheels drive the thin iron plates to flatten toward both ends, avoiding stacking and wrinkling of materials during feeding, incomplete stamping, and poor quality of stamped parts. As the fixed plate continues to move downward, the support rod drives the pressure wheels to approach the fixed rod, so that the slider is located inside the slot.

[0016] 5. The stamping die for processing the filter plate of the transmission oil filter with an edge limit mechanism fixes the material through a fixing rod to prevent the material from shifting during stamping. When the punch passes through the hole on the support block, the punch drives the waste material through the limit block and contacts the brush.
