Description
Technical field
The utility model belongs to automobile differential assembly engagement applied technical field, and in particular to one kind is nibbled applied to slip
31 flute profile moulds are forged in the backward extrusion of trap, it is adaptable to which the backward extrusion that the tooth of vehicle transmission 31 slidably engages 31 tooth engaging tooths of set is high
Effect, stably, accurately in operations for forming.
Background technology
Engaging sleeve is mainly used in the gearbox selector of automobile, collar shift, due to transmission main shaft tooth
Wheel is in normal engagement with countershaft-gear, so mobile collar shift can be used, at this moment, is carried because bearing shifting shock simultaneously
The soldered tooth number of teeth of lotus is more, and the gear teeth are not involved in gear shift, and they can not eliminate shifting shock all without premature breakdown, right
The driving safety and riding comfort of automobile still have an impact, meanwhile, still require that driver has skilled operating technology, in addition,
Because being additionally arranged engaging sleeve and constant mesh gear, increase total the moment of inertia of speed changer rotating part, therefore, current this gear shift side
Method is only applied on some less demanding gears and heavy goods vehicles speed changer, because it is public smaller between heavy goods vehicles gear,
Angular velocity difference then between shifter connector is also small, therefore uses collar shift, and can also reduce manufacturing cost and
Reduce speed changer length.
In mould, industrial production to be molded, be blow molded, extrude, the method such as die casting or forging forming, smelting, punching press obtains
The various moulds and instrument of required product.In brief, mould is the instrument for making formed article, and this instrument is by various
Part is constituted, and different moulds are made up of different parts, and it is mainly realized by the change of institute's moulding material physical state
The processing of article profile, is widely used in punching, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and engineering plastic
In the forming of compression moulding or the injection of the products such as material, rubber, ceramics.
Such product that the country is used, common procurement external product, or using machining（Internal tooth）Production, this feelings
The product that condition is produced, because gear shaping needs blank Roughing and fine machining, the processing capacity of 31 teeth is very big, one work of an equipment
As can be only done a product day, work effect pole bottom, it is difficult to meet the wilderness demand in market, along with escape to be reserved, lacks
Support is lacked, product mechanical strength, the shock resistance produced be not good, and current, for cold warm extrusion technology manufacture 31
Tooth is slidably engaged for set, and also no mould is used for carrying out backward extrusion forging 31 flute profiles shaping.
Therefore, based on above mentioned problem, the utility model provides a kind of backward extrusion for being applied to slidably engage set and forges 31 flute profiles
Mould.
