Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular to a continuous die stamping process. Background Art

[0002] A progressive die (also called a step-by-step die) is a die that can complete multiple processes at different positions in a single stroke. The blanking parts are gradually formed in a progressive die. Continuous forming is a process-intensive method that can complete multiple processes such as trimming, notching, grooving, punching, plastic deformation, and blanking on one die.

[0003] Among them, the blanking parts usually adopt long strips of material, and the conveying direction of the material strip is the same as the arrangement direction of each pressing station in the continuous mold; and each time the mold completes a stamping, the material strip is driven forward once so that the material strip moves to the next stamping station for the mold to stamp.

[0004] Finally, the material strip is processed step by step through the continuous die and then cut into individual workpieces.

[0005] like Figure 1 For the product shown, the prior art uses a synchronous distance feeding method combined with a continuous die, which results in low production efficiency and low yield. In order to solve this defect, the present application discloses a continuous die stamping process. Summary of the invention

[0008] It is further preferred that the step distance of the servo feeding and pulling material belt movement is 5mm, 10mm, and 15mm.

[0009] It is further preferred that the shape of the material strip is staggered on the upper and lower sides and on the left and right sides.

[0010] It is further preferred that the fifth station of the multi-station continuous stamping die cuts the material strip from the left side to form the final product.

[0011] The present invention achieves the following beneficial effects:

Figure 2As shown, the present application discloses a continuous die stamping process, including a servo feeder and a multi-station continuous stamping die. The servo feeder pulls the material strip to move in steps of 5mm, 10mm, and 15mm. The servo feeder pulls the material strip to the multi-station continuous stamping die for multi-step movement and performs multi-station stamping through the multi-station continuous stamping die.
