How is the stamping mold installed?

Avatar for ouzhongOuzhong
Installation of punching machine molds 1) Confirm whether the feeding holes of the mold and the cushion block are consistent. 2) After assembling the upper and lower molds, place them on the lower table, ensuring that the reference plane of the punching machine is parallel to the reference plane of the mold. 3) The lower mold should be completely fixed, and the upper mold should also be lightly fixed in advance. 4) Test punching the slider on the punching machine 20-30 times, confirm that the upper and lower molds are in a completely matching state, and then tighten the upper ...

What steel is used for stamping molds

Avatar for ouzhongOuzhong
The materials used for stamping molds include steel, hard alloys, steel bonded hard alloys, zinc based alloys, low melting point alloys, aluminum bronze, polymer materials, and so on. At present, the majority of materials used for manufacturing stamping molds are steel. The commonly used types of mold working parts materials include: carbon tool steel, low alloy tool steel, high carbon high chromium or medium chromium tool steel, medium carbon alloy steel, high-speed steel, matrix steel, as well as hard alloys, steel bonded hard alloys, and so on. 1. Carbon tool steel Carbon tool steels commonly used in molds are T8A, ... Read More

The difference between progressive die and composite die

Avatar for ouzhongOuzhong
1、 Different properties 1. Composite mold: A mold structure in which a punching machine completes multiple processes such as material cutting and punching in one stroke. 2. Progressive die: composed of multiple workstations, each of which is sequentially associated to complete different processing tasks. A series of different stamping processes are completed in one stroke of the punching machine. 2、 Different characteristics 1. Composite mold: (1) The workpiece has good coaxiality, a flat surface, and high dimensional accuracy. (2) High production efficiency, not limited by the accuracy of plate shape and size. Sometimes waste corners can also be used for ... Read More

Four maintenance precautions for continuous metal stamping dies

Avatar for ouzhongOuzhong
1. Maintenance and upkeep of convex and concave molds. When disassembling convex and concave molds, attention should be paid to the initial condition of the mold, which is beneficial for the repair of subsequent molds; If there are washers or offsets, the thickness of the washers should be engraved on the parts and noted. When disassembling and replacing the convex mold, check whether the concave mold of the material removal block is smooth, and whether the gap between the trial insertion and the concave mold is uniform; When disassembling and replacing the concave mold, is the gap between the trial ...
