Abstract

The utility model discloses a hard alloy pellet teeth pressing mold which comprises a limiter, an upper punch, a lower punch, protecting bushes and mold bushes, wherein the protecting bush is sheathed outside the mold bush, the top end of the upper punch is provided with the limiter, the mold bush comprises an upper mold bush and a lower mold bush, the upper mold bush is arranged above the lower mold bush, and the inner side of the bottom part of the upper mold bush is provided with a chamfer. The hard alloy pellet teeth pressing mold has the advantages that aiming at the pressing requirements of pellet teeth with a high chamfer and small conical degree, the forming area of the chamfer part of the pellet teeth is designed on the upper mold bush, so that the punches can be prevented from being damaged, and the service life of the mold can be greatly prolonged.

Description

A kind of hard alloy spherical-teeth compacting tool set
Technical field
The utility model relates to a kind of hard alloy spherical-teeth compacting tool set.
Background technology
In the drill bit manufacture process, for the ease of hard alloy spherical-teeth being pressed in the drill bit trousers body opening, ball tooth cylindrical base need design the chamfering of certain altitude and tapering, traditional compacting tool set with ball tooth chamfer design on mold and punching head, as Fig. 1, when the chamfering height of ball tooth higher and tapering hour, the shaping area of chamfering is the long drift cutting edge that approaches, at this moment cutting edge strength can be very poor, often because of holding the stressed premature breakage of can't stand in the pressing process.The utility model by improving method for designing, has been avoided the breakage of drift at this situation, and die life is improved greatly.
The utility model content
The purpose of this utility model is to provide a kind of hard alloy spherical-teeth compacting tool set, can effectively solve the easy premature breakage of hour cutting edge of the higher and tapering of the chamfering height of existing hard alloy spherical-teeth compacting tool set ball tooth, influences the product problem in service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of hard alloy spherical-teeth compacting tool set, comprise stop, upper punch, low punch, sheath, die sleeve, described sheath is set in outside the die sleeve, the top of described upper punch is provided with stop, described die sleeve comprises Upper Die-sleeve and lower die-sleeve, described Upper Die-sleeve is arranged on the top of lower die-sleeve, the bottom inside of described Upper Die-sleeve is provided with chamfering, described upper punch is arranged in the Upper Die-sleeve, the bottom of described upper punch is the plane, and described low punch is arranged in the lower die-sleeve.
Preferably, described sheath is cylindrical; Conveniently put into stamping machine.
Compared with prior art, the utility model has the advantages that: the utility model is at the pressing requirements of the little ball tooth of chamfering height and tapering, with ball tooth chamfer site forming area design at Upper Die-sleeve, thereby avoided the damage of drift, the service life of having improved mould greatly.
Description of drawings
Fig. 1 is existing hard alloy spherical-teeth compacting tool set structural representation;
Fig. 2 is the structural representation of a kind of hard alloy spherical-teeth compacting tool set of the utility model.
The specific embodiment
Consult the embodiment of Fig. 2 for a kind of hard alloy spherical-teeth compacting tool set of the utility model, a kind of hard alloy spherical-teeth compacting tool set, comprise stop 1, upper punch 3, low punch 5, sheath 2, die sleeve 4, described sheath 2 is set in outside the die sleeve 4, the top of described upper punch 3 is provided with stop 1, described die sleeve 4 comprises Upper Die-sleeve 41 and lower die-sleeve 42, described Upper Die-sleeve 41 is arranged on the top of lower die-sleeve 42, the bottom inside of described Upper Die-sleeve 41 is provided with chamfering, described upper punch 3 is arranged in the Upper Die-sleeve 41, the bottom of described upper punch 3 is the plane, and described low punch 5 is arranged in the lower die-sleeve 42, and described sheath 2 is cylindrical.
Bottom punch 5 is inserted in the lower die-sleeve 42, the filling carbide alloy mixture, upper punch 3 is inserted in the Upper Die-sleeve 41, put stop 1, on press, upper punch 3 depressed to stop 1 position, compound promptly is shaped to ball tooth 6 in cavity, take off stop 1 and bottom punch, and the upset mould is deviate from mould with ball tooth 6.The chamfered part of ball tooth designs the bottom inside at Upper Die-sleeve, rather than to the bottom surface of prior art design at upper punch, makes the life-span of mould improve greatly, and every secondary mould improved more than ten times in the normal following life-span of operating position, and product glossiness is better.
The above only is a specific embodiment of the utility model, but technical characterictic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
