Description

Technical Field

[0001] The utility model relates to the field of stamping dies, in particular to a stamping die with a replaceable stamping die head. Background Art

[0002] Stamping dies are special process equipment used in cold stamping to process metal or non-metallic materials into parts or semi-finished products. By installing the die on the press, pressure is applied to the material to cause separation or plastic deformation of the material, thereby obtaining the desired parts.

[0003] The existing stamping die generally uses a fixing plate and fixing screws to fix the punch head. During disassembly and installation, multiple people are often required to perform the disassembly and installation, which makes the disassembly and installation very troublesome. At the same time, the lower die of the existing stamping die is fixed with multiple sets of bolts, which makes the installation very time-consuming.

[0004] Therefore, those skilled in the art provide a stamping die with a replaceable stamping die head to solve the problems raised in the above background technology. Utility Model Content

Two sliding extrusion blocks are slidably provided on the lower end surface of the moving block, and the lower end surface of the moving block is clamped with a pressing upper mold. The clamping block includes a fixed block, and the upper and lower end surfaces of the fixed block are both fixedly provided with clamping plates.

[0008] Furthermore, a connecting block is fixedly provided on the upper end surface of the pressing module, and two fixing bolts are threadedly sleeved on the front surface of the upper end surface of the base.

[0009] Furthermore, telescopic spring columns are fixedly provided at the four corners of the lower end surface of the pressing module, and a pressing plate is fixedly provided on the lower end surface of each of the four telescopic spring columns.

[0010] Furthermore, two first connection ports are provided on the front portion of the upper end of the placement box, and a first threaded hole is provided on the front portion of the inner bottom of the placement box.

[0011] Furthermore, two sliding grooves are provided on the lower end surface of the moving block, and second connecting ports are provided at four corners of the lower end surface of the moving block.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model proposes a stamping die with a replaceable stamping die head. When in use, there is a placement box, which can place the lower die. The card interface opened on the front end surface of the lower die can be connected with the card block, so that the lower die can remain stable inside the placement box after being connected with the card block. When the lower die needs to be replaced, it is only necessary to remove the card block from the inside of the placement box and then the lower die can be pulled out from the inside of the placement box for replacement, which is very convenient.

[0016] 2. The utility model proposes a stamping die with a replaceable stamping die head. The pressing module is provided with a moving block. The sliding groove opened on the lower end surface of the moving block can enable the sliding extrusion block to move. When in use, the sliding extrusion block is moved to both sides, and the pressing upper die is placed in the middle of the two sliding extrusion blocks. The two sliding extrusion blocks are moved toward the middle so that the sliding extrusion block is clamped to the pressing upper die. The sliding extrusion block is restricted by installing a limit plate so that the pressing upper die can be clamped and fixed. When the pressing upper die needs to be replaced, only the limit plate needs to be disassembled to quickly replace the pressing upper die. BRIEF DESCRIPTION OF THE DRAWINGS
