Description
Technical field
The utility model relates to a kind of mould, especially a kind of compound die processing valve rocker pin-and-hole.
Background technology
In the prior art, known technology is the develop rapidly along with Domestic Automotive Industry, valve rocker is as one of automobile engine vital part, more and more receive the concern of Ge great producer, particularly roller class rocking arm, because it has the features such as combination property is high, rotary inertia is little, coefficient of friction is little, so be subject to the special attention of rocking arm manufacturer.
External interior roller rocker arms of producing is made up of two parts at present, and main body is rocker body, and another part is needle bearing; Assembly needs rocker body and needle bearing to be connected as a single entity, this just needs rocker body to process the pin shaft hole that can assemble with needle bearing, the serviceability of the processing precision direct influence Rocker arm assembly of pin shaft hole, existing process technology production efficiency is not high, and production precision and uniformity poor, this is the weak point existing for prior art.
Utility model content
The purpose of this utility model, be exactly for the deficiency existing for prior art, and provide a kind of technical scheme of processing the compound die of valve rocker pin-and-hole, program precision is high, compact conformation, is applicable to produce roller rocker arms pin shaft hole in enormous quantities.
This programme is achieved by the following technical measures: a kind of compound die processing valve rocker pin-and-hole, includes part of the upper die and part of the lower die; Part of the upper die comprises cope match-plate pattern, is arranged on the top shoe of cope match-plate pattern both sides, binder block and spring; Upper padding plate is provided with below the middle part of cope match-plate pattern; Patrix fixed block is provided with below upper padding plate; Concentric circle holes is had in the middle part of upper padding plate, patrix fixed block and cope match-plate pattern; Binder block is provided with in circular hole; Binder spring is provided with between binder block and cope match-plate pattern;
Part of the lower die comprises lower bolster, is arranged on lower bolster, the guide holder being arranged on lower bolster both sides, drift guide pad, drift, cylinder, the ejector beam of top in the middle part of lower bolster; The two ends, left and right of lower bolster are provided with guide holder and baffle plate; Guide holder has square hole, is provided with sliding block and is connected with top shoe in square hole; Sliding block has the screwed hole coordinated with drift; Drift guide pad is arranged on above lower bolster, and is provided with back-moving spring between drift guide pad and drift; Cylinder is arranged on below the middle part of lower bolster; Cylinder is connected with stripper; Stripper another side is connected with lower bolster; Ejector beam is connected with stripper through lower bolster; Lower bolster is provided with button and R face locating piece.
Preferred as this programme: cope match-plate pattern two ends are provided with the guide pillar be connected with lower bolster; The guide pin bushing that guide pillar is provided with.
Preferred as this programme: the quantity of ejector beam is at least one.
The beneficial effect of this programme can be learnt according to describing of such scheme, and due to rocking arm both sides punching in this scenario, blanking once completes, and production efficiency is high, reduces production difficulty, more easily ensures the size of pin shaft hole.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.

Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by a detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
This programme as shown in the figure, a kind of composite die processing roller rocker arms body pin shaft hole, comprise part of the upper die and part of the lower die, wherein part of the upper die comprises: cope match-plate pattern 1, top shoe 2 is separately installed with on this upper left right side of cope match-plate pattern 1, middle part is provided with upper mould fixed plate 11 and upper padding plate 12 simultaneously, be connected with cope match-plate pattern 1 by screw, circular hole is had in the middle part of cope match-plate pattern 11 and upper padding plate 12, binder block 10 is provided with in circular hole, binder spring 13 is arranged at bottom, product is caused to weigh wounded to avoid compaction process, at cope match-plate pattern two ends, guide pin bushing 17 is also installed, to ensure the positioning precision of the course of work.
Part of the lower die comprises: lower bolster 9, on this lower bolster 9, the left and right sides is provided with guide holder 3 and baffle plate 8, guide holder 3 has square hole, sliding block 16 is provided with in square hole, sliding block 16 has screwed hole and coordinates with drift 15, the stroke of drift 15 is regulated by adjusting nut 5, drift guide pad 6 is arranged between middle part and drift 15 and is provided with back-moving spring 14, initial position can be recovered after drift 15 is worked, middle part is also provided with lower bolster 7 simultaneously, with the ejector beam I 20 that leads, ejector beam II 23, ejector beam III 24, ejector beam IV 25, lower bolster 7 is provided with location button 19 and R face locating piece 22, to ensure the accurate positioning of product, thus raising machining accuracy, stripper 26 connects lower bolster 9 and cylinder 27 respectively by screw,
The process of work is that forcing press is connected with cope match-plate pattern 1, cope match-plate pattern 1 drives top shoe 2, by oblique angle, power is changed on sliding block 16, because drift 15 and sliding block 16 are for being fixedly connected with, therefore the drift 15 that can promote both sides works, and completes punch work simultaneously, the compressed air that punching terminates rear connection removes waste material, cylinder 27 promotes each ejector beam work, removal converted products simultaneously.
Above-described embodiment of the present utility model is only used to the utility model example is described, and is not the restriction to embodiment of the present utility model.To those of ordinary skill in the art, also can make multi-form change and variation on the basis of the above description, cannot give all embodiments exhaustive here.
Every belong to the technical solution of the utility model the apparent change of amplifying out or variation be still in the row of protection domain of the present utility model.
