Abstract

The utility model relates to a gap-adjustable trimming die, which comprises an upper die plate and a lower die plate. A female die sleeve and a guide sleeve are arranged on the upper die plate. Four female die splits which form one group are arranged in the female die sleeve. The female die sleeve and the female die splits are respectively fixed on the upper die plate, a plurality of screw holes are arranged at the side of the female die sleeve, a gap is left between the female die sleeve and each female die split, the size of each gap is respectively adjusted though the screw holes which pass through the side of the female die sleeve and a plurality of adjusting screws which prop against each female die split. By adopting the gap-adjustable trimming die, the size of the female die can be adjusted according to the variation of the season temperature and the size, so that the gap between the female die and a die casting workpiece is in an optimal state at any time and the yield is improved.

Description

The edger of adjustable clearance

Technical field

The utility model relates to a kind of edger, specifically relates to a kind of edger of adjustable clearance.

Background technology

Edger is the diel that is used for excising die casting cast gate overflow lip and burr, is to make workpiece carry out plastic deformation along the closed outline of mould under the effect of pressure.But the edger of die casting is different in essence with stamping die in general sense, and the size of the die size of stamping die decision part, the working portion size of edger but are by the size decision of die casting.

Die casting takes off from mould, need just can excise cast gate, overflow lip and burr with edger after supercooling.And the die casting workshop has very big variation in different room temperatures in season, winter indoor temperature generally about 7 ℃, indoor temperature will reach about 37 ℃ when reaching 30 ℃ when outdoor temperature in summer.This environment temperature of room temperature has very big influence to the cooling velocity of die casting, and die casting generally need cool off and carry out punching and edge-cutting about one hour again.In the time of this hour, the variation meeting of environment temperature brings variation on the size to die casting, and the amount of contraction of same die casting can differ 0.3～0.5mm.

The edger die of die casting all is a monolithic construction at present, and promptly integral body four edge dies are directly installed on the cope match-plate pattern, and the die size of making after finishing cannot be regulated.Big or hour when pressur casting size, the gap is too small between diel die and the workpiece, occur easily pulling, misrun or depression, the problem such as residual excessive that cast gate place and overfall perhaps occur, thereby cause the mass defect of punching press, be difficult to guarantee the quality after the die casting punching press, percent defective is very high.

Summary of the invention

At the defective of prior art, the utility model provides the edger of a kind of die size adjustable, adjustable clearance that yield rate is high.

For reaching above-mentioned purpose, the utility model has adopted following technical scheme:

A kind of edger of adjustable clearance, comprise cope match-plate pattern and lower bolster, die case and guide pin bushing are installed on the cope match-plate pattern, establish one group of totally four cavity splits in the die case, die case and cavity splits are fixedly installed on the cope match-plate pattern respectively, a plurality of screws are established in the die case side, all leave the gap between die case and every cavity splits, and the size in this gap is regulated by screw, a plurality of adjustment screw of contact on every cavity splits of passing on the die case side respectively.

The utility model also can further be realized by following scheme:

The edger of described adjustable clearance, wherein, described cavity splits is made of jointly left piece, right piece, preceding piece and back piece, left side piece and right piece are processed with the inclined-plane respectively near the forward and backward two ends of die case one side, respectively install a corner block between inclined-plane and die case, adjustment screw and corner block are fixed together in order to regulate gap between left and right sides piece and die case.

The edger of described adjustable clearance, wherein, 45 ° of described inclination angle of inclined plane, the length 10～15mm of inclined-plane two right-angle sides.

The edger of described adjustable clearance, wherein, described forward and backward piece is regulated by the adjustment screw that is symmetricly set in die case center line both sides respectively.

The edger of adjustable clearance of the present utility model, adopt the design of assembled piece type die, with adjustment screw every cavity splits is regulated, to change the size of die, make it make the gap between die and the die casting workpiece be in optimum state all the time along with the variation of different seasonal temperatures and size is regulated.Efficiently solve the difference along with season, the difference of environment temperature and the variation that brings size have guaranteed the quality after the die casting punching press, improve yield rate.The utility model is simple in structure, and is easy to use, economical and practical, has preferable social economic value, suitable applying.

Description of drawings

Fig. 1 is the structural representation of the edger cope match-plate pattern of the utility model adjustable clearance;

Fig. 2 is the A portion enlarged diagram of Fig. 1;

Fig. 3 is the B-B portion sectional structure schematic diagram of Fig. 1.

The specific embodiment

As Figure 1-3, a kind of edger of adjustable clearance comprises cope match-plate pattern and lower bolster (not shown), and die case 2 and guide pin bushing 6 are installed on the cope match-plate pattern 1.Die case 2 is fixedly mounted on the cope match-plate pattern 1 by soket head cap screw.One group of cavity splits 3 is installed in the die case 2, and this group cavity splits 3 is made of jointly left piece, right piece, preceding piece and back piece, and left and right piece and forward and backward piece all are fixed on the cope match-plate pattern 1 with soket head cap screw 4.Cope match-plate pattern is provided with screwed hole, is through hole on the cavity splits, in the screwed hole of soket head cap screw by the screw-in of the through hole on the cavity splits cope match-plate pattern cavity splits is fixed on the cope match-plate pattern.Leave the gap of 1mm between through hole on the cavity splits and the soket head cap screw, so just can utilize adjustment screw to realize moving of cavity splits.All leaving the gap between the left piece of die case 2 and cavity splits 3, right piece, preceding piece and the back piece regulates with convenient.A plurality of screws are offered in die case 2 sides, adjustment screw pass each screw respectively contact on left piece, right piece, preceding piece and back piece, adjust the gap of 3 of die case 2 and cavity splitses by the flexible distance of regulating adjustment screw.

For the ease of adjusting, promptly the forward and backward two ends near a side of die case respectively process an inclined-plane in the outside of left piece and right piece, and inclination angle of inclined plane is 45 °, the length 10～15mm of inclined-plane two right-angle sides.And between left piece and right piece inclined-plane and die case 2, adding corner block 7, the inclination angle of corner block 7 and length and inclined-plane are suitable.Adjustment screw 5 is separately fixed on each corner block 7, drives corner block by left-handed or dextrorotation adjustment screw 5, left piece and right piece is laterally moved, to regulate the lateral clearance between left piece and right piece and the die case 2.Preceding piece 2 and back piece can directly move forward and backward with adjustment screw 5, and adjustment screw 5 is symmetricly set in die case center line both sides, the axial clearance before can regulating between piece and back piece and the die case 2.

The above is preferred embodiment of the present utility model only, is not that the utility model is done any pro forma qualification.Any change that is equal to, modification or differentiation etc. that all those skilled in the art utilize the technical solution of the utility model that the foregoing description is made all still belong in the scope of technical solutions of the utility model.
