Description

A kind of Precision Machining mold of gear

Technical field

The utility model relates to fields in terms of the processing of gear, are mainly concerned with changing for the mold processing configuration aspects of gear Into and design, especially when be related to a kind of Precision Machining mold of gear.

Background technique

In the fast development of current industrial, the use of gear becomes especially frequently, almost can all use in all industries A large amount of various gear drives, current used gear is typically all to use in terms of the transmission of heavy industry, right The tooth accuracy of gear is more demanding, is typically all to carry out excision forming using to wheel blank in Gear Processing at this stage, Although being processed using the method for cutting, processing program is relatively simple, will cause the waste of material for beating beam, in high-volume It can lose more than gain when production, the serious production cost for increasing gear, while iron in processing workshop is also resulted in using cutting method It is excessive to consider Dust Capacity to be worth doing, seriously affects the safety of staff.

Therefore it provides a kind of Precision Machining mold of gear is led to by improving to gear working method and structure It crosses after high temperature heating and softening, is carrying out extrusion forming by gear teeth extrusion molding dies, can effectively reduce material Waste, reduces the production cost of gear, while realizing ELEMENTARY INTRODUCTION TO NON, can effectively reduce the Dust Capacity in processing workshop, drops Influence of the dust to staff in environment when low processing, just become those skilled in the art's urgent need to resolve the problem of.

Utility model content

The purpose of the utility model is to provide a kind of Precision Machining molds of gear, by gear working method and knot Structure improves, and after high-temperature heating softening, is carrying out extrusion forming, Neng Gouyou by gear teeth extrusion molding dies The reduction waste of material of effect, reduces the production cost of gear, while realizing ELEMENTARY INTRODUCTION TO NON, can effectively reduce in processing workshop Dust Capacity, reduce processing when environment in influence of the dust to staff.

To solve technical problem described in background technique, the utility model uses following technical scheme:

A kind of Precision Machining mold of gear, including wheel blank and processing mold, the processing mold are wrapped in gear The outer surface of base, processing mold are set as medianly zygomorphic two processing half module, process uniformly to be equipped on half module inner wall and use Slot is squeezed in the molding teeth of teeth, and by the way that the mold pressurizing unit of tightening can be connected step by step between two processing half modules, Mold pressurizing unit is set as two groups of both ends for being symmetrically fixed on processing half module, the mold pressurizing unit and two processing half modules Constitute the Precision Machining mold of gear.

Preferably, the mold pressurizing unit includes screwing bar, pushing block and screwing block, the pushing block and is screwed Block is separately fixed at two processing half module sides, screws bar one end and connect with the driving motor processed on half module, screws bar and wear separately One end, which is crossed pushing block and is embedded into, screws screwing in hole on block.

Preferably, described screw is connected between bar and pushing block by bearing.

Preferably, two groups of fixations for preventing processing mold spinning are symmetrically arranged on two sides before and after the upper processing half module Device, the fixation device include fixed link and fixing sleeve, and fixed link and fixing sleeve, which respectively correspond, is fixed on two processing half On mould.

Preferably, it is set on the processing half module anti-there are four being equipped with for squeezing the ventilation mouth taken a breath, and in mouth of taking a breath It slips through the net hole.

The beneficial effects of the utility model are:

1), after by high-temperature heating softening, extrusion forming, Neng Gouyou are being carried out by gear teeth extrusion molding dies The reduction waste of material of effect, reduces the production cost of gear.

2) it, realizes ELEMENTARY INTRODUCTION TO NON simultaneously, the Dust Capacity in processing workshop can be effectively reduced, when reducing processing in environment Influence of the dust to staff.

Detailed description of the invention

In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, below will be to institute in embodiment Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only to record in the utility model Some embodiments be also possible to obtain other drawings based on these drawings for those of ordinary skill in the art.
