Description

A kind of tapered end face bulging by punch mould

Technical field

The utility model is related to a kind of expanding die, and in particular to a kind of tapered end face bulging by punch mould, belongs to machinery Technical field of mold.

Background technology

So-called bulging, is in the presence of mould, to force blank thickness thinning and surface area increase, to obtain part geometry The processing method for stamping of shape, bulging process is different from deep-drawing technique, and the plastically deforming area of blank is confined in the range of deformed area, Material is not shifted to outside deformed area, is not also externally entering deformed area, is thinning realizing by the local of blank.

The punch of solid soft mode bulging adopts rubber, polyurethane or PVC（Poly- ammonia ethene）Deng material, using soft convex during bulging Mould compressive deformation simultaneously forces sheet material to recline to concave die cavity.Because solid soft mode bulging can improve some deficiencies of firm mould bulging （Such as the uneven, mould structure of workpiece deformation is complicated）, therefore solid soft mode bulging has good application prospect.

The content of the invention

To solve the deficiencies in the prior art, the purpose of this utility model is the defect for overcoming prior art, there is provided a kind of Tapered end face bulging by punch mould, using expanding die of the present utility model, when outer cover class part is processed, mould structure is simple Rationally, it is easy to operate, it is adapted to produce in batch.

In order to realize above-mentioned target, the utility model is adopted the following technical scheme that：

A kind of tapered end face bulging by punch mould, including upper bolster, die shoe, pressing block, polyester ammonia block, die, push rod, It is characterized in that：Also include discharge arm, lock module, drift, the die includes the left die and right die of full symmetric mirror image, The die shoe top is provided with annular frustum, and its conical surface is contacted with left and right die and coordinates left and right die to position, the top Bar is arranged in die shoe, and the pressing plate is fixedly connected with upper bolster, and the lock module is flexibly connected by discharge arm with pressing plate, institute State drift to be fixedly connected with upper bolster, the pressing block is fixedly connected with the pressing plate, the polyester ammonia block is positioned over left and right die and closes In the inner chamber formed after mould.

A kind of aforesaid tapered end face bulging by punch mould, it is characterised in that：The drift lower end be male-tapered, the punching Briquetting upper end is provided with frustum inner chamber, and male-tapered is engaged with conical internal cavity.

A kind of aforesaid tapered end face bulging by punch mould, it is characterised in that：The discharge arm middle part is coated with spring.

A kind of aforesaid tapered end face bulging by punch mould, it is characterised in that：The inner chamber of the lock module is taper type.

A kind of aforesaid tapered end face bulging by punch mould, it is characterised in that：The push rod top is annular.

The beneficial effect that the utility model is reached：（1）Expanding die of the present utility model, in processing outer cover class part When, mould structure advantages of simple is easy to operate, is adapted to produce in batch.（2）The frustum inner chamber design of pressing block so that bulging Workpiece afterwards is uniform.

Description of the drawings

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

The implication of reference in figure：1st, left die, 2, workpiece, 3, polyester ammonia block, 4, lock module, 5, upper bolster, 6, punching Head, 7, pressing plate, 8, pressing block, 9, discharge arm, 10, right die, 11, die shoe, 12, push rod.

Specific embodiment

The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.

Participate in Fig. 1, expanding die of the present utility model, including upper bolster 5, die shoe 11, pressing block 8, polyester ammonia block 3rd, die, push rod 12, discharge arm 9, lock module 4, drift 6, die includes the left die 1 and right die 10 of full symmetric mirror image, The top of die shoe 11 is provided with annular frustum, and its conical surface is contacted with left and right die 1,10 and coordinates left and right die 1,10 to position, Push rod 12 is arranged in die shoe 11, and pressing plate 7 is fixedly connected with upper bolster 5, and lock module 4 is connected by discharge arm 9 with the activity of pressing plate 7 Connect, drift 6 is fixedly connected with upper bolster 5, pressing block 8 is fixedly connected with pressing plate 8, polyester ammonia block 3 is positioned over left and right die 1,10 In the inner chamber formed after matched moulds, for the ease of the workpiece 2 after shaping is taken out from die, die is divided into into two pieces of left and right.

The lower end of drift 6 is male-tapered, and the upper end of pressing block 8 is provided with frustum inner chamber, and male-tapered is engaged with conical internal cavity, 2 The individual conical design being engaged causes the workpiece for forming out more uniform.

The middle part of discharge arm 9 is coated with spring, the setting not only effect of reset of spring, it is often more important that, in punching press Cheng Zhong, applies pressure and promotes the firm left and right die 1,10 of locking of lock module 4.

The inner chamber of lock module 4 is taper type, and the design of taper type causes lock module 4 with left and right die 1,10 contacts area Increase, increasing friction force, it is often more important that because profile is back taper itself can be very good to play positioning action.

The top of push rod 12 is annular, and the push rod 12 of annular effectively can slightly eject left and right die 1,10, to go Except the workpiece 2 after bulging, at the same circulus material-saving and it is lightweight, intensity is exited in reduction.

Expanding die of the present utility model, its specific work process is as follows：

When upper bolster 5 is descending, band dynamic pressure plate 7 is descending, and die is depressed and locked by lock module 4, and upper bolster 5 is continued traveling downwardly, Drift 6 contact pressing block 8, and the frustum of the lower end of drift 6 slowly into pressing block 8 frustum inner chamber, compressed polyester ammonia block 3, into Workpiece 2 of the type wall portion with dome.After shaping, upper bolster 5 is up, and pressing plate is up, and push rod 12 slightly ejects left and right die 1,10, Subsequently the workpiece 2 after shaping is taken out.

The utility model the above be only preferred embodiment of the present utility model, it is noted that for this technology neck For the those of ordinary skill in domain, on the premise of without departing from the utility model know-why, can also make it is some improvement and Deformation, these are improved and deformation also should be regarded as protection domain of the present utility model.
