Abstract

The utility model relates to a die shank with a pressure device, which at least comprises a die shank main body, an elastic part, a top plate and a stop screw, wherein the die shank main body is fixed on an upper die base, a through hole is arranged in the die shank main body, and the upper end of the through hole is provided with a threaded hole for installing the stop screw; the top plate is movably arranged in the through hole, and the elastic piece is arranged between the top plate and the stop screw. The utility model has the advantages that: the elastic piece, the top plate and the set screw form a pressure device on the premise that the main body of the die handle is taken as a base body, the pressure device transmits pressure to the upper stripping plate through the dowel bar and transmits the pressure to form pressure force or stripping force and the like, and the problems that the existing pressure device is insufficient in installation space, insufficient in pressure occurs in production and the like are effectively solved; the die structure can be widely applied to die structures such as compound dies, bending dies and the like, and has the advantages of simple processing, lower cost and convenient maintenance or replacement.

Description

Die shank with pressure device

Technical Field

The utility model relates to the technical field of mold, especially, relate to a die shank with pressure device.

Background

In stamping die, the die shank is outstanding in the cylindrical stamping die part of upper die base top surface, the during operation die shank stretches into in the press slider hole and is pressed from both sides tightly fixed for being connected between stamping die and the press, and pressure device mainly used presses the material, take off the material, liftout etc. because pressure device special action in stamping die, often because of the interior position space of mould is not enough, must do simplification means such as reduce the stroke or reduce pressure to pressure device, cooperate it to install in narrow and small space, cause in the production can draw the material because of the not enough problem of pressure emergence, do not take off the condition such as material, influence the normal clear of production.

The conventional pressure supply device has 3 schemes: the first scheme is that a template is added or thickened to ensure that enough space is available for installing a pressure device, and the second scheme is that: a spring box is added on the upper die base, and the third scheme is as follows: a knockout pin of a press is utilized. However, these 3 solutions have the following disadvantages: first, the cost of the two solutions is greatly increased by increasing the amount of materials and processing. The second scheme can only provide a knockout force, does not provide a swaging force, and the product is not flat.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a die shank with pressure device to overcome not enough among the above-mentioned prior art.

The utility model provides an above-mentioned technical problem's technical scheme as follows: a die shank with a pressure device at least comprises a die shank main body, an elastic piece, a top plate and a set screw, wherein the die shank main body is fixed on an upper die base, a through hole is formed in the die shank main body, and the upper end of the through hole is provided with a threaded hole for mounting the set screw; the top plate is movably arranged in the through hole, and the elastic piece is arranged between the top plate and the stop screw.

The utility model has the advantages that: the elastic piece, the top plate and the set screw form a pressure device on the premise that the main body of the die handle is taken as a base body, the pressure device transmits pressure to the upper stripping plate through the dowel bar and transmits the pressure to form pressure force or stripping force and the like, and the problems that the existing pressure device is insufficient in installation space, insufficient in pressure occurs in production and the like are effectively solved; the die structure can be widely applied to die structures such as compound dies, bending dies and the like, and has the advantages of simple processing, lower cost and convenient maintenance or replacement.

On the basis of the technical scheme, the utility model discloses can also do following improvement.

Further: the elastic element is a nitrogen spring, a super glue or a spiral spring.

Drawings

Fig. 1 is a schematic structural view of a die shank with a pressure device according to the present invention.

In the drawings, the components represented by the respective reference numerals are listed below:

1-a die shank main body, 110-a through hole, 120-a threaded hole, 2-an elastic part, 3-a top plate, 4-a dowel bar, 5-a set screw, 6-an upper stripping plate and 7-an upper die holder.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Example 1

As shown in fig. 1, a die shank with a pressure device at least comprises a die shank main body 1, an elastic member 2, a top plate 3 and a set screw 5, wherein the die shank main body 1 is fixed on an upper die base 7, a through hole 110 is formed in the die shank main body 1, and a threaded hole 120 is formed at the upper end of the through hole 110 for installing the set screw 5; the top plate 3 is movably arranged in the through hole 110, and the elastic element 2 is arranged between the top plate 3 and the set screw 5.

Example 2

As shown in fig. 1, this embodiment is further optimized based on embodiment 1, and it specifically includes the following steps:

the elastic element 2 is a nitrogen spring, a super glue or a spiral spring.

In the specific implementation:

elastic component 2, roof 3 and stop screw 5 constitute a pressure device based on die shank main part 1 under the prerequisite of base member, and pressure device passes through dowel steel 4 again and gives pressure transmission and take off board 6 and pass and become pressure power or take off the material power etc. on, effectively solve current pressure device because of the installation space is not enough, appear the insufficient scheduling problem of pressure in the production.

Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the scope of the present invention.
