Abstract

The utility model relates to a stamping and drawing die for round covers. The die comprises a push rod, an upper die base, a lower die base, a female die and a male die, wherein two sides of the upper die base are sequentially connected with fixing plates and the female die downwards to form a cavity, the push rod penetrates through the upper die base to be connected with a push plate, the male die opposite to the cavity is arranged on the lower die base, a separation layer is arranged between the male die and the cavity, material press plates are arranged on two sides of the male die, positioning plates are arranged at upper ends of the material press plates, the material press plates are connected with the lower die base through guide posts, and sliding friction tapes are arranged in positions where the guide posts penetrate through the lower die base. According to the stamping and drawing die for the round covers, blanks are pressed consistently, and the product quality is improved.

Description

Dome punching stretch mould

Technical field

The utility model relates to a kind of cold punching technology processing technique field, is specifically related to a kind of dome punching stretch mould.

Background technology

Punching stretch mould is to utilize the mould being arranged on pressing equipment (being mainly forcing press) to exert pressure to blank, make it produce plastic deformation, utilize movably mode of mould part, by blank stretch forming, thereby obtain a kind of pressure processing method of required part (being commonly called as stamping parts), circular cover body is common a kind of converted products in cold punching die processing, the use of diel, working (machining) efficiency is improved, bring convenience to users, existing mould normally utilizes return spring to realize the movement of both mold ends position, but return spring is because compression is more, the resistance producing is larger, whole process is easily changed to the stressed of blank, make the intensity of the mechanical work that the each several part of blank is subject to inconsistent, affect the quality of product.

Utility model content

The purpose of this utility model is to provide the dome punching stretch mould that a kind of pressurized is consistent, improve product quality.

To achieve these goals, the utility model provides a kind of dome punching stretch mould, comprise push rod, upper bolster, die shoe, die and punch, described upper bolster both sides are connected with in turn fixed head downwards and die forms cavity, described push rod connects upper bolster and is connected with push pedal, on described die shoe, be provided with the punch relative with cavity, between described punch and described cavity, be provided with every dead level, described punch both sides are provided with holding pad, described holding pad upper end is provided with location-plate, described holding pad is connected with die shoe by guide pillar, described guide pillar is provided with sliding friction band by die shoe position.

Adopt a kind of dome of technique scheme to have following advantage with punching stretch mould: described blank is placed on holding pad, regulate location-plate that workpiece is fixed on die, when forcing press declines, die stamping blanks, die moves downward together with holding pad, because punch is fixed, poor with holding pad formation morpheme, thereby by blank stretch forming, owing to being provided with the sliding friction band that coefficient of friction is identical between guide pillar and lower bolster, so resistance can not change, the stressed processing intensity of blank is consistent, thereby has improved product quality.

As preferred version, consider and can change the push pedal of corresponding size according to the shape of product, between described push rod and push pedal for removably connecting.

As preferred version, consider better control guide pillar, make the movement locus of guide pillar consistent, described guide pillar is 2, and between guide pillar, is provided with balancing pole, and described balancing pole is arranged on guide pillar bottom, both be convenient to operating personnel's operation, and can have guaranteed again the pressure balanced that is subject to of workpiece.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model dome punching stretch mould embodiment;

Wherein: 1, push rod, 2 upper bolsters, 3, die, 4, holding pad, 5, die shoe, 6, guide pillar, 7, push pedal, 8, fixed head, 9, location-plate, 10, punch.

the specific embodiment

Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:

As shown in Figure 1, a kind of dome punching stretch mould, comprise push rod, upper bolster 2, die shoe 5, die 3 and punch 10, described upper bolster 2 both sides are connected with in turn fixed head 8 downwards and die 3 forms cavity, described push rod 1 connects upper bolster 2 and is connected with push pedal 7, on described die shoe 5, be provided with the punch relative with cavity 10, between described punch 10 and described cavity, be provided with every dead level, described punch 10 both sides are provided with holding pad 4, described holding pad 4 upper ends are provided with location-plate 9, described holding pad 4 is connected with die shoe 5 by guide pillar 6, described guide pillar 6 is provided with sliding friction band by die shoe 5 positions, in addition as preferred version, consider and can change the push pedal 7 of corresponding size according to the shape of product, between described push rod 1 and push pedal 7 for removably connecting, as preferred version, consider better control guide pillar 6, make the movement locus of guide pillar 6 consistent, described guide pillar 6 is 2, and is provided with balancing pole between guide pillar 6.

Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
