Description
Technical field
IC engine link rod field is the utility model is related to, more particularly to a kind of compound trimming die tool for producing connecting rod.
Background technology
Connecting rod is used to connect piston and bent axle, and active force suffered by piston is transmitted into bent axle, and the reciprocating motion of piston is turned
It is changed into the rotary motion of bent axle, connection rod set is born the gas load that piston pin transmits and itself swung and piston group is back and forth used to
Property power effect, the size and Orientations of these power is all periodically variable, and the alternate loads such as connecting rod is compressed, stretched are made
With.Connecting rod must have enough fatigue strength and the rigidity of structure, fatigue strength deficiency, often cause gonnecting rod body or connecting-rod bolts
Fracture, and then produce the major accident that complete machine is destroyed.If insufficient rigidity, body of rod flexural deformation and the mistake of big end can be caused
Circle deformation, cause the eccentric wear of piston, cylinder, bearing and crank-pin etc..The production mould of connecting rod has very to the mechanical strength of connecting rod
It is big to influence, so Piston Rods Die is great to the Influence of production of connecting rod.
The A of Chinese patent notification number CN 105697529, publication date on June 22nd, 2016, a kind of connecting rod is disclosed, is had
The small rod hole that rotatably can be connected with piston, have separate type configuration, rotatably can be connected with crank it is big
Tie rod holes, the gonnecting rod body between connecting rod eye, Dalian rod aperture have the big end and energy quilt positioned at the connecting rod side
Connecting rod cap in twist-on to the big end, through hole is arranged in the both sides of Dalian rod aperture in connecting rod cap, in big end
Arrangement flushes with the through hole and penetrates the screwed hole of big end, screw penetrated through via holes and is screwed into screwed hole.According to
The present invention provides, and in the connecting rod of this type, big end deviates from side of connecting rod cap, in the region of each screwed hole at it
In have depression, depression point to Dalian rod aperture direction and relative to axis of thread eccentric setting.The connecting rod of this type makes
The last thread turn that may make each screwed hole region in point load minimize, and thus considerably increase the connecting rod
Service life.Traditional connecting rod production mould is separated, and trimming, punching and correction need three machine three process, work
Skill is cumbersome, and the utility model solves in connecting rod forging and stamping production in a procedure while carries out asking for trimming, punching and correction
Topic.
The content of the invention
The technical problems to be solved in the utility model is how to design a kind of compound trimming die tool for producing connecting rod to solve to connect
Carry out the problem of trimming, punching and correction in bar forging and stamping production simultaneously in a procedure.
The utility model is that technical scheme is used by solving the above problems：A kind of compound trimming die for producing connecting rod
Tool, it is characterised in that fixed including guide pillar guide pin bushing, upper bolster, die shoe, die shank, edger, edger stripper, edger
Mould, punch fixing plate, drift and upper push pedal, the top half of the composite die are sequentially connected from top to bottom on plate, shaping
Mould in die shank, upper bolster, upper push pedal, edger fixed plate, edger and shaping, the latter half of compound trimming die tool from
Top to bottm is sequentially connected edger stripper, drift, punch fixing plate and die shoe, the guide pillar guide pin bushing be located at upper bolster and
Between die shoe, the upper push pedal is connected on die shank by the circular hole at upper bolster center, and the edger fixed plate passes through cunning
Dynamic guide pillar is connected in push pedal, and mould is fixed on the lower section of edger fixed plate on the edger and shaping, and the drift is consolidated
Fixed board is fixed on die shoe by sliding guide column, and drift and the edger stripper is fixed on the top of punch fixing plate.
Preferably, the number of the guide pillar guide pin bushing is two.
Preferably, the guide pillar guide pin bushing includes center guide pillar and outside guide pin bushing.
Preferably, there is a rectangular recess in the section of the upper push pedal, the rectangular recess with the upside of edger fixed plate
Male cooperation.
Preferably, the center guide pillar is hydraulic pressure guide pillar.
The beneficial effects of the utility model are：In connecting rod forging process trimming, punching are completed using a kind of mould simultaneously
With the work of correction three process.
Brief description of the drawings
Fig. 1 is construction profile of the present utility model.
In figure：1st, guide pillar guide pin bushing, 2, upper bolster, 3, die shoe, 4, die shank, 5, edger, 6, edger stripper, 7, cut
Side mould fixed plate, 8, mould in shaping, 9, punch fixing plate, 10, drift, 11, upper push pedal.
Embodiment
Below by specific embodiment, and with reference to accompanying drawing, specific embodiment of the present utility model is made further specific
Explanation.
The utility model is that technical scheme is used by solving the above problems：Fig. 1 is that a kind of production of the utility model connects
Bar compound trimming die tool construction profile, the production connecting rod compound trimming die tool include guide pillar guide pin bushing 1, upper bolster 2, under
Die holder 3, die shank 4, edger 5, edger stripper 6, edger fixed plate 7, mould 8, punch fixing plate 9, drift 10 in shaping
With upper push pedal 11.The top half of composite die is sequentially connected die shank 4, upper bolster 2, upper push pedal 11, edger from top to bottom
Mould 8 in fixed plate 7, edger 5 and shaping, the latter half of compound trimming die tool are sequentially connected edger discharging from top to bottom
Plate 6, drift 10, punch fixing plate 9 and die shoe 3.Guide pillar guide pin bushing 1 between upper bolster 2 and die shoe 3, guide pillar guide pin bushing 1
Quantity is two, and guide pillar guide pin bushing 1 includes center guide pillar and outside guide pin bushing, and wherein center guide pillar uses hydraulic pressure guide pillar.Upper push pedal 11
It is connected to by the circular hole at the center of upper bolster 2 on die shank 4, there are rectangular recess, rectangular recess and edger in the section of upper push pedal 11
The male cooperation of the upside of fixed plate 7, the projection of the rectangular recess of upper push pedal 11 and edger fixed plate 7 when upper push pedal 11 pushes
It can fit together perfectly altogether, so upper push pedal 11 is more uniform to the pressure of edger fixed plate 7.Edger fixed plate 7
It is connected to by sliding guide column in upper push pedal 11, mould 8 is fixed on the lower section of edger fixed plate 7, drift on edger 5 and shaping
Fixed plate 9 is fixed on die shoe 3 by sliding guide column, and drift 10 and edger stripper 6 are fixed on the upper of punch fixing plate 9
Side.In forging process, die shoe 3 is fixed on the table, increases the hydraulic pressure below center guide pillar first so that composite abrasive
Top half lifting, then between blank is put into the top and the bottom of mould, then reduce the hydraulic pressure of guide pillar guide pin bushing 1, die shank 4 is solid
It is scheduled on stamping machine, stamping machine moment increases the pressure of die shank 4, blank is forged and pressed, pressure passes to upper push pedal from die shank 4
11, moment pressurization is carried out to mould 8 in edger 5 and shaping by upper push pedal 11, now drift 10 can produce moment punching to blank
Power, so as to go out the hole needed for connecting rod, the significant shear power between edger 5 and edger stripper 6 causes unnecessary blank
It is cut and, trimming clout can be stayed on edger stripper 6, and at the same time mould 8 can carry out shaping to blank in shaping.Institute
To pass through the once forging and stamping of composite die of the present utility model, it is possible to complete the three of trimming, punching and the correction of connecting rod blank
Procedure, reduce machine and artificial use, while greatly reduce the total energy consumption of three process.
Embodiment described above is a kind of preferable scheme of the present utility model, not the utility model is made any
Formal limitation, there are other variants and remodeling on the premise of without departing from the technical scheme described in claim.
