Assembly jig of A and B station die head

Abstract

An assembly jig of A and B station die heads relates to a work jig for maintaining, assembling and disassembling the numerical control press top die. The invention provides an assembly jig of A and B station dies, which utilizes the self-positioning key of A and B station top dies to overcome the rotational degree of freedom, and jigs through surface contact, thus avoiding the damage to the outersurface. The assembly jig comprises a fixing seat, a movable seat hinged with the fixing seat, and a locking device, wherein the fixing seat and the movable seat are respectively provided with a semicircle; the fixing seat and the movable seat can form a round profile slightly smaller than the external circle profile when being folded; and one of the semicircle is provided with a groove for holding a B station die head positioning key. The invention utilizes a pair of fixing seat and movable seating with circular surfaces to jig the cylinder die, realizes the jig of surface contact, and effectively avoids the damage to the outer surface of the die. The invention has good use effect, avoids the damage to the die when in maintenance, and has strong adaptability, being capable of adapting totwo different dies.

Description

technical field [0001] The invention relates to a tooling fixture for maintenance, assembly and disassembly of a die on a numerically controlled punching machine, in particular to an assembling fixture which can be simultaneously applied to the upper die heads of stations A and B on a numerically controlled turret punching machine. Background technique [0002] The turret of the CNC turret punch press is equipped with mold stations in four different installation forms, A, B, C, and D. With the popularity of CNC turret punching machines, the molds for the above-mentioned stations have gradually become standard parts in the industry. During long-term use, the punch of the upper die will be worn and damaged, or the guide rod will be deformed and other failures, and the cost of replacement is very high. Many units with maintenance capabilities generally adopt maintenance methods to repair the faulty upper mold. During maintenance, it is necessary to clamp the upper mold assemb...

AI Technical Summary

Problems solved by technology

At present, vise is generally used to clamp the upper mold assembly during repair. The jaws of the vise have high hardness and friction surface, and are in line contact with the upper mold assembly, and it is easy to damage the outer surface of the upper mold assembly.

The outer surface of the upper die assembly and the mold sleeve of the CNC stamping machine have requirements for matching accuracy. After the internal failure of the upper die is repaired by the above method, external damage will occur
