Description
Technical field
The invention belongs to advanced material forming technique field, be specifically related to a kind of spline roll forming equipment Worm-gear type diameter changing mechanism.
Background technology
Spline is to be used for the motion and the part of moment of torsion between transmitter shaft and the axle in the mechanical system; Splined is as a kind of linking intensity height, compact conformation, connecting mode that reliability is high; Have that contact area is big, bearing capacity is high, centering property is good, guidance quality is good, stress is concentrated advantages such as less, the axle and the strength reduction of hub be less; Be widely used in numerous mechanical industries, for example space flight and aviation, automobile, tractor, boats and ships, lathe, engineering machinery etc.
In recent years along with rapid development of automobile industry; Swift and violent increase of the demand of spline and instructions for use improve constantly; Processing technology and equipment to spline have proposed new challenge, shortcomings such as cut intensity is high, productivity ratio is low because the conventional spline cutting technology exists, mechanical performance and surface quality difference, and the Plastic Forming processing technology belongs to the ELEMENTARY INTRODUCTION TO NON category; Production efficiency is high, high, the good product performance of stock utilization, becomes the main flow processing technology of involute spline gradually.Spline rollforming technology is as important a kind of in the spline Plastic Forming processing technology, and it is high to have shaping splined surfaces quality, and performance is good; Mould is made, installs simple; Die life is long, the production efficiency advantages of higher, thereby this technology is widely used in the production reality of spline.
But spline rollforming technology exists processing spline modulus and problems such as the number of teeth is limited, mould versatility difference at present, and one of reason that these problems occur is whether the spline roll forming equipment possesses the reducing function.Reducing function for existing most of spline roll forming equipments mainly contains following several kinds: one, do not possess the reducing function, realize the rollforming of different size spline through changing rolling die; Two, through manual adjustment rolling die installing mechanism, be aided with bolt, realize reducing, this diameter changing mechanism adjustment difficulty, the adjustment precision is low; Three, promote the rolling die installing mechanism through traditional hydraulic cylinder, realize reducing, this diameter changing mechanism complex structure, the space is big.It is thus clear that there is the adjustment difficulty in existing spline roll forming equipment diameter changing mechanism, precision is low, complex structure, the problem that the space is big.
