Description

A kind of hard alloy top hammer mold

Technical field

The utility model belongs to hard alloy processing technique field, and in particular to a kind of hard alloy top hammer mold.

Background technology

Hard alloy top hammer at present（Hereinafter referred to as top hammer）Production relies primarily on die forming, and traditional die structure includes mould Set, upper punching, heelpiece, control block etc..During using mold production top hammer, to die sleeve and dividing valve bottom when due to die forming Pad will produce extruding force, when top hammer forming number reach one timing, extruding force can to die sleeve and divide valve heelpiece generate destruction so that Die sleeve and valve heelpiece is divided to occur rupturing or irregular deformation so that hard alloy top hammer needs to re-replace mold, causes into This waste, while can also influence the quality of top hammer production.

Utility model content

The purpose of this utility model is to provide a kind of hard alloy top hammer molds, to solve to propose in above-mentioned background technology The problem of.

To achieve the above object, the utility model provides the following technical solutions：A kind of hard alloy top hammer mold, including bottom Seat, die sleeve and the ring set for being set in die sleeve outer ring, the pedestal includes dividing valve heelpiece and square cushion block, described that valve heelpiece and side is divided to pad Block connection is integral, and the groove for offering circular ring shape on valve heelpiece, the groove setting is divided to divide valve heelpiece upper surface, groove Inside it is connected with cylindrical die sleeve, groove bottom end both sides offer endoporus to dividing in valve heelpiece, fixed setting in the endoporus There is horizontal positioned spring, top hammer to be processed, the top die of the top hammer to be processed are installed between pedestal in the die sleeve Upper punching is equipped in set, the upper punching and top hammer to be processed are adapted on the inside of cylindrical die sleeve, and the ring set is two and Ban Ring-like steel ring is mutually clamped composition, and ring set inner ring surface is connected with compatible rubber ring.

Preferably, the round and smooth processing in the bottom end of the die sleeve, the groove bottom end are provided with the arc to match with die sleeve bottom end Shape slot.

Preferably, the endoporus, which is opened in, groove and divides in the outside of valve heelpiece, in one end of the spring is fixed on Hole inner wall, the other end are extend out in groove.

Preferably, the both sides for two groups of semi-circular steel rings being mutually clamped on the ring set are arranged with connection sheet, two groups It is mutually fixed by the connection of bolts and nuts between the symmetrical connection sheet, the bolt passes through two groups of connection sheets, bolt The other end and by being screwed between nut and connection sheet.

The technique effect and advantage of the utility model：The hard alloy top hammer mold, by being provided with reeded point Valve heelpiece makes die sleeve be connected in point valve heelpiece, while die sleeve and valve heelpiece access section being divided to be provided with one end closely die sleeve, another The spring of valve heelpiece madial wall is closely divided at end, and die sleeve, when with dividing valve heelpiece to be clamped, spring is in compressive state so that die sleeve When interior top hammer to be processed carries out compression molding, the pressure for being molded generation acts on die sleeve, and die sleeve is by spring and divides valve bottom Pad carries out coming down in torrents for pressure, it is therefore prevented that die sleeve bottom end and the fragmentation condition for dividing valve heelpiece to be generated when passing through repeatedly molding are matched simultaneously The annular ring set being arranged on the outside of molding set upper side makes ring set can adapt to more by the fixation between the connection sheet of ring set both sides The different die sleeve of group diameter, while die sleeve upper end also being protected the phenomenon that damaging and dividing occur in molding, it improves Die sleeve and the access times for dividing valve heelpiece, reduce the consumption of cost, ensure the quality of production.
