Description

Technical Field

[0001] The utility model relates to the technical field of molds, and particularly relates to a cross-drive side punching structure for a stamping die. Background Art

[0002] In a progressive stamping die, affected by the space of the front and rear material tapes, some side punches cannot install driving blocks on the lower die base. Usually, side punches are arranged on the stripper plate, and then a conical locator is added between the stripper plate and the lower die base. However, the existing method has the following disadvantages: when there are deviations in product springback and misfeeding of the material tape, the gap between the stripper plate and the lower die will increase, resulting in deviation of the gap between the side punch head and the cutting edge of the die, and causing damage to the cutting edge and the punch.

[0011] Further, the pull-back hook drives the slider to move upward.

[0012] The advantages of the cross-drive side punching structure of the stamping die of the present utility model are as follows:

[0013] When there is no space in front of and behind the side-punched strip, the side punching drive is installed on the lower die carrier; it is found through observation that there is space on both sides of the strip to design the drive block, so the side punching drive block is installed on both sides of the strip, and the slider forms a slider spanning both sides; the product structure is stable and easy to process; through the structural design of this application, the technical problem that the side punching cannot install the drive block on the lower die carrier due to the influence of the front and rear strip space is solved.
