Description

Technical Field

[0001] The invention relates to the technical field of cold heading stamping dies, in particular to a multifunctional stamping forming die for cold heading parts and a use method thereof. Background Art

[0002] The cold heading stamping die is a die that extrude the blank into a specific shape by cold extrusion and punching, and then punches holes on the extruded product. A convex flange refers to a flange in which the edge of the middle hole is higher than the outer edge of the flange. The flange forming is divided into two parts: cold heading and punching. When cold heading and punching are divided into two dies, the space after cold heading needs to be transferred to the punching part for punching. This method takes time to transfer the workpiece, and the workpiece produced needs to be manually separated from the waste and the product, resulting in reduced product production efficiency.

[0003] The defects of existing cold heading stamping dies are: 1. The prior art KR1019810000733B1 discloses a cutting table material cutting and conveying device. This technology does not have a structure that combines cold heading and stamping dies. After cold heading, the product needs to be transferred to the stamping die for stamping. Transferring the product takes time, resulting in reduced production efficiency. Therefore, a multifunctional stamping die for cold heading parts that can combine cold heading and stamping without transferring the product is needed to solve this problem.

[0004] 2. The prior art JP2016221532A discloses stamping forming, which does not have a structure for automatically removing products and waste from the mold. Workers need to manually remove the products. Therefore, a multifunctional stamping mold for cold heading parts that can automatically remove products after cold heading is needed to solve this problem.

[0005] 3. The prior art KR101125469B1 discloses a stamping die, which does not have a structure for classifying and collecting products and waste after cold heading stamping. Waste and products cannot be collected after production of the die is completed, resulting in the need to collect and clean the fallen waste, wasting time and reducing production efficiency. Therefore, a multifunctional stamping die for cold heading parts that can classify and collect products and waste after production is needed to solve this problem.

[0006] 4. The prior art CN103861937B discloses a stamping die, which does not have a structure for classifying and collecting products and waste. When an additional collection structure is provided, it is impossible to ensure that the products inside the collection structure remain flat, and the accumulated products may easily affect the entry of subsequent products, causing subsequent products to fall outside the collection structure or causing subsequent products to be unable to enter the collection structure. Therefore, a multifunctional stamping die for cold heading parts having a collection structure and preventing products from piling up inside the collection structure is needed to solve this problem.
