The manufacturing process of the packaging steel strip sheet progressive horizontal
　　 Because the progressive die is more complicated than the general thin plate die, the manufacturing accuracy is higher. Especially when there are more jumps, the more difficult it is to manufacture. It is especially difficult to guarantee the matching accuracy of the male and female molds of the upper and lower molds.
　　 When using wire cutting to produce progressive dies, the punch fixing plate, the discharge (guide) plate and the concave template can be combined together, and the wire cutting process can be performed at the same time to ensure that the cutting edge of the concave die after the punch is fixed, The accuracy of the position between the holes of the discharge plate, the processing method is relatively simple. The manufacturing process is as follows: ① Make the punches and side blades; ② Fix the punch and side blades on the upper mold base with screws according to the layout size (sometimes a fixed plate can be processed according to the specific situation to fix the convex Mold, and then fasten the fixed plate with the punch on the upper mold base); ③put the four small guide posts of the discharge plate into the hole of the upper mold base; ④cast between the punch and the discharge plate Low melting point alloy; ⑤Sleeve the backing plate on the four small guide posts of the guide plate, and emboss the backing plate with a convex mold; ⑥Process the backing plate hole with the traces pressed by the fitter; ⑦Lay the concave mold on the hole with the hole ⑧Use the shim plate as the craft die, punch the concave model hole with the convex die; ⑨Remove the die, trim the cutting edge and deburr, ⑩Process unloading plate, install guide plate and concave template; ⑪Assemble test punch.
