Introduction to the overall installation case of the plum blossom cushion stamping die

The plum blossom cushion die can be assembled after the die base and the male and female dies are assembled. The stamping part die should be installed with the lower die first. The assembly process is as follows. ① Place the fixed plate of the assembled die on the lower die base, align the die 13 as the assembly reference position according to the center line, clamp it with a parallel chuck, and drill a cone on the lower die base through the screw holes. Remove the die fixing plate, drill the threaded bottom hole and tap the thread on the lower die seat according to the taper. Re-place the die fixing plate on the lower die seat, align it, and fasten it with screws. Drill the reaming pin hole and drive in the pin for positioning. ② Install the positioning plate on the fixed plate of the assembled die. ③ When drilling the unloading screw holes, put the unloading plate 14 on the punch 12 that has been installed in the fixed plate, and put a suitable height equal-height shim between the fixed plate and the unloading plate 14, and use parallel clamps. Clamp it with the head. Drill a conical socket on the fixing plate according to the screw holes on the unloading plate, and drill the screw holes on the fixing plate according to the conical socket after disassembly. ④ Insert the male mold 12 that has been installed in the fixed plate into the hole of the female mold. Padded an appropriate height of equal height pad iron between the concave mold 13 and the lower mold base 15, put the pad 7 on the punch fixing plate 8, install the mold base, and use the parallel chuck to connect the upper mold base 4 and the convex mold base. The mold fixing plate 8 is clamped. Drill a cone on the upper mold seat through the punch fixing plate, and then press the cone to drill holes after disassembling, and then use screws to slightly tighten the upper mold seat, backing plate, and punch fixing plate. ⑤ When adjusting the matching gap of the convex and concave molds, use the light transmission method to adjust the matching clearance of the convex and concave molds, use paper as the stamping material, hit the mold handle with a hammer, and perform a test punch. If the punched pattern has a neat outline , There is no burr or burr is uniform, indicating that the gap between the convex and concave molds is uniform. If there are only local burrs, the gap is uneven, and you should re-adjust until the gap is uniform. ⑥ After adjusting the gap, tighten the fastening screws of the punch fixing plate. Drill the reaming positioning pin hole and install the positioning pin. ⑦ Install the spring and discharge screw to check whether the movement of the discharge plate is flexible. When the discharge plate is in the lowest position under the action of the spring, the lower end surface of the punch should be shrunk in the hole of the discharge plate by about 0.5-1mm. ⑧ Before inserting the stamping part mold into the manual mold base, the mold should be inspected according to the design drawing in order to find the problem in time and reduce unnecessary repeated installation and disassembly. ⑨ Test punching under production conditions. Through the test punching, you can find the design and manufacturing defects of the stamping part die, find out the cause, make appropriate adjustments and repairs to the stamping part die, and then perform the test punching until the die can work normally , If the qualified parts are punched out, the assembly process of the mold ends.
