Description
Technical field
The present invention relates to machine components to use cold extruding formation process production field more particularly to a kind of cold-extruded of coupling yoke
Press processing method.
Background technology
Coupling yoke is a kind of widely applied standard component, is such as used in automobile, farm machinery, engineering machinery and mechanical equipment
Connection.Traditional coupling yoke is all made of cutting and the mode of die casting produces, and this mode is in processing and fusion-casting process
Energy consumption is higher, and pollution is higher, and in today that requirement of the country for environmental protection further increases, the production technology of coupling yoke is apparent
It urgently improves.
Invention content
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, a kind of connection of innovation is provided
Pitch processing method-cold extruding formation process.
The present invention is to be achieved by the following technical programs：
A kind of cold extruding processing method of coupling yoke, includes the following steps：
(1) shaping：By mold squeezing shaping it is square cylinder by round steel after cutting, and rectangular by round steel fixed length cutting
One end of cylinder is at hemispherical；
(2) shaping centers：By after workpiece turning made from step (1) by mold squeezing shaping, in square cylinder
Hemispherical one end squeezes out square central blind hole, and the other end squeezes out chamfering；
(3) square hole is squeezed in necking down：Workpiece made from step (2) is passed through into mold squeezing shaping so that chamfering one end of workpiece
Necking down is simultaneously stretched at cylinder, the other end side of squeezing out blind hole, and one group of square blind hole is thinner than another group to side wall to sidewall thickness
Thickness；
(4) threaded hole is squeezed：The workpiece of step (3) is put into mold and squeezes threaded hole at cylindrical member at one end in workpiece necking down；
(5) trimming：Relatively thin one group of the square blind hole that step (4) is made to workpiece cuts off side wall, forms straight slot；
(6) it perforates：The square central blind via bottom perforation of workpiece made from step (5) is got through.
The beneficial effects of the invention are as follows：
The coupling yoke prepared using above-mentioned production technology is had the following advantages that：
(1) use cold extrusion mode by the contours profiles extrusion forming of coupling yoke, coupling yoke after molding is by extruding
After reason, mass density higher, mechanical performance is more preferable.
(2) part raw material are lost in entire production process only in trimming and perforation procedure, the utilization rate of raw material is high,
Production cost can be reduced.
(3) production process uses cold extrusion mode completely, relative to traditional casting mode, saves the energy and not will produce
Pollution, it is environmentally protective.
(4) production efficiency is hundred times of traditional processing technology or more.

Specific implementation mode
In order to make those skilled in the art more fully understand technical scheme of the present invention, below in conjunction with the accompanying drawings and most
The present invention is described in further detail for good case study on implementation.
As shown in Figure 1, the present invention includes the following steps：
(1) shaping：Round steel is unreeled and fixed length cutting, by mold squeezing shaping is square cylinder by round steel after cutting；
Workpiece a after step (1) shaping, the crops for rotation blocked are shaped to regular hemispherical by cold extrusion；
(2) shaping centers：Workpiece made from step (1) is passed through into mold squeezing shaping, squarely cylinder, hemispherical one
End is squeezed into square central hole, squeezes square hole for subsequent processing and prepares.Workpiece b after step (2) shaping, another end margin are circle
Angle；
(3) oblong aperture is squeezed in necking down：Workpiece made from step (2) is extruded into cylinder by the necking down of mold one end, one end is logical
Cross extruding so that the square blind hole squeezed out in step (2) is further elongated, perforative one group of square blind hole to sidewall thickness as possible
Thin, workpiece c square blind holes in extrusion process are extruded depth and increase after step (3) shaping, and the surrounding hole wall height of square blind hole
Accordingly increase, and since one group of side wall will be removed, therefore the thinner thickness of the side wall so that it saves material convenient for cutting
Material, further increases materials'use rate, workpiece plan structure c1 after step (3) shaping, it is seen that one group opposite side side wall is relatively thin；
(4) threaded hole is squeezed, by workpiece made from step (3), mold is put into and squeezes threaded hole, form d1 workpiece, squeeze threaded hole
After overlook d1.
(5) trimming：By the relatively thin one group of side wall excision of the square blind hole of workpiece made from step (4), workpiece after step (5) trimming
E forms straight slot, workpiece plan structure e1 after step (5) trimming, it is seen that excision rear blind hole has been straight slot；
(6) it perforates：The circle blind via bottom perforation of workpiece made from step (5) is got through, the work after step (6) perforation has both been obtained
Part f also just completes the production for completing coupling yoke.
The coupling yoke prepared using above-mentioned production technology is had the following advantages that：
(1) use cold extrusion mode that the profile extrusion of coupling yoke is molded produced coupling yoke after extrusion process,
Its mass density higher, mechanical performance are more preferable.
(2) part raw material are lost in entire production process only in trimming and perforation procedure, the utilization rate of raw material is high,
Production cost can be reduced.
(3) production process uses cold extrusion mode completely, relative to traditional casting mode, energy conservation and environmental protection, energy consumption
More former technique saves 80% or more.
(4) production efficiency is hundred times of traditional handicraft or more.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
