Description

Technical Field

[0001] The utility model belongs to the technical field of stamping, in particular to an alloy punch which is easy to install and disassemble. Background Art

[0002] A punch refers to a metal part on a stamping die in a mechanical tool, also called a punch rod, a needle or a punch. It is installed on the stamping die to perform continuous blanking, punching and breaking operations to separate or plastically deform the processed material, thereby obtaining the required finished product or semi-finished product.

[0003] No matter what material is used for the existing punch, after a long period of work, the material will wear out and the punch will definitely need to be replaced. The existing punch is fixed to the mounting seat of the upper die by a hexagon socket bolt during installation. It needs to be installed and disassembled by specific tools during the installation and disassembly process, which is time-consuming and labor-intensive, and is not convenient for workers to quickly replace, thus affecting work efficiency. Utility Model Content

[0006] Furthermore, the mounting assembly includes a first mounting rod, a second mounting rod, a connecting platform and a second receiving groove, the second receiving groove is opened on one side of the punch mounting seat, the second receiving groove is communicated with the first receiving groove, the second mounting rod is slidably arranged in the second receiving groove, the connecting platform is fixedly arranged at the top end of the first receiving groove away from the second receiving groove, and a compression spring is fixedly arranged at one end of the connecting platform close to the second receiving groove, and the other end of the compression spring is connected to the second mounting rod.

[0007] Furthermore, the first mounting rod is vertically fixed above the punch end, an L-shaped fixing rod is provided at the bottom of one end of the second mounting rod located in the first accommodating groove, and a mounting groove for inserting the L-shaped fixing rod is opened on the first mounting rod, and the L-shaped fixing rod can be slidably inserted into the mounting groove.

[0008] Further, the top end of the first mounting rod is arranged in a trapezoidal shape, and the first mounting rod is vertically arranged on the right side above the punch end.

[0009] Furthermore, the protection component is fixedly arranged at the bottom of the punch mounting seat, and the protection component includes a threaded connection sleeve and a limiting ring. The limiting ring is fixedly arranged at the bottom of the punch mounting seat, and the threaded connection sleeve is threadedly arranged on the outside of the limiting ring.

[0010] The beneficial effects of the utility model are:

[0011] The utility model can fix the punch end in the first receiving groove by arranging a mounting assembly in the first receiving groove, and the mounting assembly includes a first mounting rod, a second mounting rod, a connecting platform and a second receiving groove. When the punch end needs to be inserted, at this time, since the top end of the first mounting rod is set in a trapezoidal shape, the L-shaped fixing rod can be pushed open, so that the first mounting rod can be smoothly inserted into the first receiving groove. At the same time, after the first mounting rod is inserted, the L-shaped fixing rod will also be inserted into the mounting groove on the first mounting rod. When the punch is working, the L-shaped fixing rod will be fastened in the mounting groove on the first mounting rod under the action of centripetal force to prevent the punch end from falling off. When the operator needs to replace the worn punch end, he only needs to press the second mounting rod exposed outside the second receiving groove. At this time, the L-shaped fixing rod moves synchronously with the second mounting rod, and the bottom end of the L-shaped fixing rod will be taken out of the mounting groove on the first mounting rod, and the worn punch end can be removed at this time. The utility model is simple to operate, saves time and labor, improves the work efficiency of workers, and has high practicality. BRIEF DESCRIPTION OF THE DRAWINGS
