Description

A kind of anti-bending heading die

Technical field

The utility model belongs to forge die technical field, is specifically related to a kind of anti-bending heading die.

Background technology

Heading die belongs to the one in forge die, utilize patrix and counterdie matched moulds to pressurize, make the forging mold that the height of blank workpiece reduces, area of section increases, its upset ratio that can reach is general all below 2.5, so-called upset ratio refer to blank length before jumping-up thick with pier before the ratio of blank diameter, adopt existing heading die, upset ratio is once more than 2.5, blank workpiece easily produces twin drum distortion, if continue to exert pressure, also can produce Fold, thus cause scrapping of blank workpiece.

Utility model content

The purpose of this utility model is: for Problems existing in heading die in above-mentioned prior art, and provide a kind of anti-bending heading die, upset ratio can reach 2.5-3, and blank workpiece is not flexible.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of anti-bending heading die, comprise cope match-plate pattern, jumping-up upper die and lower die plate, jumping-up counterdie, counterdie backing plate is fixedly installed above lower bolster, described jumping-up counterdie is fixedly installed above counterdie backing plate, the centre of counterdie backing plate and jumping-up counterdie is provided with counterdie cushion block, be provided with ejector beam bottom counterdie cushion block, ejector beam is embedded in the middle of counterdie backing plate, is supported by counterdie backing plate; Between counterdie backing plate below ejector beam and lower bolster, liftout voussoir is installed; Jumping-up counterdie top is fixedly installed the fairlead that can hold jumping-up patrix.

Preferably, in the middle of counterdie backing plate and jumping-up counterdie, be also provided with the locating ring adjusting counterdie cushion block center, locating ring is placed on counterdie cushion block lower surface, and forms interference fit.

Preferably, jumping-up counterdie is made up of cylinder top and cube bottom, and fairlead is placed on cylinder top, and forms interference fit with cylinder top, and by cube lower support.

Owing to have employed technique scheme, the beneficial effects of the utility model are:

A kind of anti-bending heading die of the present utility model, fairlead is provided with between counterdie and patrix, when hydraulic press control cope match-plate pattern is descending, the contact site of upper die and lower die is all in fairlead, guarantee that blank workpiece easily produces diastrophic position in fairlead, limited by the guiding of fairlead, therefore can not produce flexural deformation; This heading die is also provided with liftout voussoir, and by hitting liftout voussoir, workpiece can be ejected fast, and structure is simple, easy to operate.

Accompanying drawing explanation

Fig. 1 is heading die structural representation of the present utility model.

Fig. 2 is the thick die cut view of pier of the present utility model.

Mark in figure: 1-cope match-plate pattern, 2-jumping-up patrix, 3-fairlead, 4-jumping-up counterdie, 5-counterdie backing plate, 6-lower bolster, 7-liftout voussoir, 8-counterdie cushion block, 9-locating ring, 10-ejector beam, 11-blank workpiece.

Detailed description of the invention

With reference to Fig. 1, Fig. 2, a kind of anti-bending heading die of the present utility model, comprise cope match-plate pattern 1, jumping-up patrix 2, lower bolster 6, jumping-up counterdie 4, above lower bolster 6, be fixedly installed counterdie backing plate 5, above counterdie backing plate 5, be fixedly installed described jumping-up counterdie 4, counterdie backing plate 5 is provided with counterdie cushion block 8 with the centre of jumping-up counterdie 4, be provided with ejector beam 10 bottom counterdie cushion block 8, ejector beam 10 is embedded in the middle of counterdie backing plate 5, is supported by counterdie backing plate 5; Between counterdie backing plate 5 below ejector beam 10 and lower bolster 6, liftout voussoir 7 is installed; Jumping-up counterdie 4 top is fixedly installed the fairlead 3 that can hold jumping-up patrix 2.The locating ring 9 adjusting counterdie cushion block 8 center is also provided with in the middle of counterdie backing plate 5 with jumping-up counterdie 4, locating ring 9 is placed on counterdie cushion block 8 lower surface, and formation interference fit, by locating ring 9, the centerline collineation of adjustable counter-die backing plate 5 and the thick counterdie of pier, bending when more effectively preventing jumping-up.

Jumping-up counterdie 4 is made up of cylinder top and cube bottom, fairlead 3 is placed on cylinder top, and form interference fit with cylinder top, and by cube lower support, guarantee that fairlead 3 is firmly fixed, and during jumping-up, during jumping-up, jumping-up patrix 2 can enter in fairlead 3 easily, with jumping-up counterdie 4 matched moulds.

Anti-bending heading die of the present utility model, when blank workpiece 11 jumping-up of upset ratio more than 2.5, need upset forging process to be divided into two steps, namely need two covers heading die of the present utility model, first set mould realizes pre-upsetting, and the second mold realizes complete jumping-up.

When first set mould jumping-up, when the slide block of hydraulic press drives the upper die component such as cope match-plate pattern 1 and jumping-up patrix 2 descending, the die cavity of jumping-up patrix 2 contacts hot blank workpiece 11, the blank workpiece 11 of heating is under pressure and starts distortion, when jumping-up patrix 2 lower plane touches plane on jumping-up counterdie 4, namely this heading die reaches closed height, due to the effect of fairlead 3, blank workpiece 11 can not produce flexural deformation, and hot blank workpiece 11 completes pre-upsets.Use the parts such as lance to knock liftout voussoir 7, utilize the inclined-plane of liftout voussoir 7 to make ejector beam 10 up, power is upwards delivered on blank workpiece 11 by counterdie cushion block 8, realize ejecting of blank workpiece 11.

Take out blank workpiece 11, utilize waste heat, and by the second cover heading die, repeat above upset forging process, make blank workpiece 11 be deformed into required shape.
