Description
Technical field
The utility model belongs to a kind of Machining of Connecting Rod instrument, specifically a kind of mould for connecting rod blank pressure-sizing shaping,
It is mainly used in the cold-coining correction of connecting rod blank angularity.
Background technology
Because engine link forging warpage easily occurs in punching, trimming, heat treatment and removing surface, cause connecting rod hair
The faces parallel of base, flatness and symmetry are overproof, in order to ensure connecting rod forging higher form and position tolerance and technical requirements, one
As after removing surface process carry out cold-coining correction.
Connecting rod blank（See Fig. 1,2）Cold-coining correcting process, be controls connecting rod blank quality one of critical process, one
As require that angularity size of the connecting rod blank in all directions of end face is no more than 0.3mm, can be right when angularity is overproof
Follow-up machining processes produce large effect and bury hidden danger of quality.The cold-coining correction of blank be typically in smoothing press or
Carried out on hydraulic press or friction press, coining die used is mostly heavier, is overall or inserted, except mould
It is high outer to have cost, die change, debugging are wasted time and energy, and the connecting rod of every kind of model is required to whole set replacement in pressure-sizing timing, and
And connecting rod blank positioning is also not accurate enough, during operation, because the different connecting rod blanks of the custom of each operator are placed in die location
On situation it is also variant, often there is the problem of connecting rod pressure-sizing vestige position and inconsistent pressure-sizing amount, cause unqualified, user
It is unsatisfied with cooperation unit.Other mould fatigue stress often occur in blank coining process, change is easily worn in mould bottom surface
Shape, whole crack of die is caused to scrap.For these reasons, it is necessary to the pressure-sizing Correction Die is improved, to adapt to connecting rod
Large-scale production.
Utility model content
The utility model technical issues that need to address and purpose are, according to the mould of existing connecting rod blank pressure-sizing shaping
Existing deficiency, design a kind of universal mold for connecting rod blank pressure-sizing shaping.Fundamentally overcome the pressure-sizing of connecting rod blank
Correction qualification rate is low, die cost is high phenomenon, reach the pressure-sizing correction mass for effectively ensureing connecting rod blank, reduce mould into
This, improves production efficiency, meets the needs of large-scale production.
Main technical schemes of the present utility model：Universal mold include die holder, V-arrangement regulating block, small end of connecting rod face location-plate,
Connecting rod bar portion locating piece, big end face location-plate, alignment pin, limited block, bolt, screw, concrete structure：At the middle part of die holder
Position, by alignment pin and screw installing connecting rods bar portion locating piece, against the right of connecting rod bar portion locating piece, installed by screw
Small end of connecting rod face location-plate, a V-arrangement regulating block is installed on the location-plate of small end of connecting rod face, and V-arrangement regulating block passes through screw and die holder
It is fixed, the left side of connecting rod bar portion locating piece, by alignment pin and the big head location-plate of screw installing connecting rods, the two of rip fence
End, a limited block is respectively installed by bolt.
The utility model is proved by practical application：Purpose of design is fully achieved, the mold design is reasonable, accurate positioning,
Connecting rod blank pressure-sizing correction qualification rate brings up to more than 98% by 75%；By changing individual part, you can suitable for a variety of rule
The connecting rod blank pressure-sizing shaping of lattice, has saved substantial amounts of Making mold expense, and cost drops to original less than 10%；Installation is adjusted
Examination is simple, quick, overcomes that original mould installation and debugging are cumbersome and the phenomenon of low production efficiency, disclosure satisfy that the need of large-scale production
Ask.
Brief description of the drawings
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in further detail.
