Description
Technical field
The utility model is related to auto industry technical field more particularly to a kind of trimming mould bases for being used to be driven forging shaft.
Background technology
Traditional trimming die carrier structure mainly includes top mold frame, lower mold holder, upper and lower drift, and top mold frame and lower mold holder are processed respectively
There is dovetail groove, trimming punch and trim die are machined with dovetail corresponding with mould bases dovetail groove respectively.When in use, trimming punch
It is fixed on upper and lower mould bases by dovetail and inclined wedge respectively with trim die.Traditional die carrier structure and installation have the following problems：
1. the active force that trimming punch is subject to when working is transmitted to top mold frame surface by dovetail bottom surface, due to dovetail bottom surface
Area be less than trimming punch work when forced area, can more be concentrated for delivery to the active force on top mold frame surface, cause
The abrasion of the top mold frame part and deformation velocity finally make top mold frame must because of local excessive abrasion deformation higher than other positions
It must be overhauled, reduce the service life of top mold frame.In the course of work, there is unbalance stress in trimming punch, due to
Dovetail floor space is less than trimming punch forced area, so trimming punch can be there are torsional deformation, after leading to trimming when serious
Forging bends or even scraps.
2. installation trimming punch and when trim die are fixed using drift mold, need repeatedly to adjust and assembly key
Iron can complete the installation of mold.Installation process is very high to the operation skill requirement of worker, and labor intensity is big and installation is fixed
Reasonability judged by rule of thumb by worker completely, it is too strong to the subjective operational capacity dependence of worker, assembling consistency cannot
Ensure.
3. being influenced by self structure, during the work time, drift can be because be loosened by impact force.Because edger is only
It fixes by the drift of side, so edger can also move after drift loosens, declines so as to cause forging trimming quality, sternly
The accident that trimming punch hits trim die occurs during weight, causes to damage to mold and equipment.In order to ensure to work normally, worker
Per tour needs multiple checks and fastening drift, increases labor intensity, reduces production efficiency.
4. it during the work time, can be sent out during the motion since there are gaps, sliding block between bead cutter sliding block and guide rail
It is raw to shake.Trimming punch is fixed on top mold frame on sliding block, so top mold frame and trimming punch also shake with sliding block.It is cutting
In crack approach, if trimming punch shakes seriously, mold cavity cannot coincide with forging, forging can be caused to be crushed out of shape.
5. when installation mold, need firmly to hit drift can just make it is close between drift and mold, drift and mould bases
Ground is bonded, and achievees the purpose that fixing mould.In this case, there is only stress for the dovetail groove of mould bases, mold dovetail and drift
Deformation can also have abrasion.Mold installation is not only influenced when formation abrasion is serious, production efficiency is reduced, has an effect on forging trimming
Quality.
Utility model content
In view of the deficiencies of the prior art, which provides a kind of for being driven the trimming mould bases of forging shaft, by trimming
Complete plane is processed at the back side of punch-pin and trim die, is fixedly connected by bolt with top mold frame and lower mold holder, is made trimming
The forced area stress that the contact area of punch-pin and top mold frame is more than when trimming punch works is more dispersed, mitigates the part of working face
Abrasion greatly prolongs the service life of mould bases.
To achieve these goals, which provides a kind of for being driven the trimming mould bases of forging shaft, including to
The top mold frame of trimming punch is installed, to install the lower mold holder of trim die and guidance set, the trimming punch with it is upper
The mounting surface of mould bases is plane, and more than the working face of trimming punch, and top mold frame and trimming punch opposite position offer
Positioning spline, top mold frame and trimming punch are located by connecting by positioning key；The lower mold holder offers to install trim die
Rectangular recess, the groove offers through-hole, and trim die offers tapped in the corresponding position of the through-hole
Slot, groove and trim die are bolted to connection, and the guidance set includes the guide post being arranged in top mold frame and sets
Put the guide sleeve on lower mold holder, the guide sleeve and lower mold holder offered with guide post opposite position it is consistent with guide post diameter
Endoporus.
Advantageous effect
1st, the utility model is a kind of for being driven the trimming mould bases of forging shaft, including installing the top mold frame of trimming punch
With to install the lower mold holder of trim die, and the mounting surface of trimming punch is plane, more than its working face, mitigates working face
Concentrated wear, greatly prolong the service life of top mold frame；
2nd, a kind of trimming mould bases for being used to be driven forging shaft of the utility model, top mold frame and the corresponding position of trimming punch
It processes positioning spline, positions and fixes connection using bolt during installation, it is not only easy for installation, consistency is good, it can also avoid
Trimming punch moves in the course of work；Lower die erection opens up groove, and each direction of groove sets two bolts to be used for adjusting
Whole and installation trim die, the installation and adjustment of bolt are more convenient, and two bolts in same direction have interlocked
It is more stable with trim die during, work, it is possible to reduce to the inspection number of trim die position, so as to improve production efficiency；
3rd, the utility model is a kind of for being driven the trimming mould bases of forging shaft, increases guide sleeve guide post knot on trimming mould bases
Structure improves guiding accuracy, avoids the excessive influence to trimming quality in equipment gap, improves the consistency of trimming quality.
