Abstract
The utility model is related to one kind being used for the molding decompressor of steel pipes with straight, including support base and punch rod, support base is located at the underface of punch rod, boss is equipped in the middle part of the punch rod bottom, both sides form the step surface being recessed inwardly, and the boss bottom both ends are fixed with a shrapnel respectively, and shrapnel one end is connect with boss, the other end is connect by spring with step surface, which can be alleviated or avoided and cause impression to steel plate.
Description
Technical field
The utility model is related to one kind being used for the molding decompressor of steel pipes with straight, belong to steel pipes with straight manufacturing technology neck
Domain.
Background technology
Steel pipes with straight needs to carry out multiple stepping punching press to steel plate using decompressor during being made, so that steel plate is curved
Bent camber, since punch rod bottom is mostly fixed plane or arc surface.Punching press is carried out using the punch rod that bottom surface is plane
When, punch rod both sides easily to the steel plate of bending formed impression, and use bottom surface be arc surface punch rod carry out punching press when, circular arc
Impression easily is caused to the steel plate of plane in the top in face.
Utility model content
In order to solve the problems in the existing technology the utility model, provides a kind of can be reduced or avoided and is caused to steel plate
Impression is used for the molding decompressor of steel pipes with straight.
In order to achieve the above object, the utility model proposes technical solution be：One kind being used for the molding punching of steel pipes with straight
Pressure device, including support base and punch rod, support base are located at the underface of punch rod, are equipped among the punch rod bottom convex
Platform, both sides form the step surface being recessed inwardly, and the boss bottom is fixed with a shrapnel, is connect with boss in the middle part of shrapnel,
Both ends are connect by spring with step surface respectively.
Above-mentioned technical proposal is further designed to：When spring is in relaxation state, shrapnel is located at boss bottom surface
In same plane.
The boss bottom surface is in downwardly projecting arc-shaped.
When spring-compressed to limiting condition, the shrapnel is located at boss bottom surface in same arc surface.
The diameter of boss bottom surface circular arc is identical as steel pipes with straight diameter.
The spring is equipped with multiple, and is uniformly arranged along shrapnel length direction in boss both sides.
The beneficial effects of the utility model are：
Punch rod bottom is shrapnel in the utility model, and in punching course, with the bending of steel plate, shrapnel can be also bent
The shape moment of deformation, punch rod bottom surface keeps consistent with the shape at steel plate punched position, can effectively mitigate rushing for fixed shape
Compression bar causes impression to steel plate.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific implementation mode
Below in conjunction with the accompanying drawings and the utility model is described in detail in specific embodiment.
Embodiment one
As shown in Figure 1, a kind of decompressor of the present embodiment is used to carry out multiple stepping punching press, including support base to steel plate
With punch rod 1, support base is located at the underface of punch rod 1, boss 2 is equipped among 1 bottom of punch rod, and both sides form and are recessed inwardly
Step surface 3,2 bottom of boss is fixed with a shrapnel 4, and 4 middle part of shrapnel is connect with boss 2, both ends respectively by spring 5 and
Step surface 3 connects, and middle spring 5 uses high-strength spring in the present embodiment.
When spring 5 is in relaxation state, shrapnel 4 is generally aligned in the same plane the decompressor of the present embodiment with 2 bottom surface of boss
It is interior, since punch rod bottom is strip, so in order to enhance the elasticity of shrapnel 4, spring 5 is equipped with multiple, multiple springs
It is uniformly arranged along shrapnel length direction.
Embodiment two
The decompressor structure and embodiment one of the present embodiment are essentially identical, the difference is that boss 2 in the present embodiment
Bottom surface is downwardly projecting arc surface.
When spring 5 is in relaxation state, shrapnel 4 is parallel with steel plain, when spring 5 is compressed to limiting condition, bullet
Piece 4 is located at 2 bottom surface of boss in same arc surface.
The diameter of 2 bottom surface circular arc of boss is identical as steel pipes with straight diameter in the present embodiment.
In punching course, shrapnel gradually reduces spring the decompressor of above-described embodiment under the reaction of steel plate, and
Keep punch rod bottom shape consistent with steel plate punched position shape, to mitigate the impression caused by steel plate.
The utility model is not limited to the various embodiments described above for the molding decompressor of steel pipes with straight, all using equivalent
The technical solution that alternative obtains is all fallen in the range of the requires of the utility model protection.
