Abstract
The utility model relates to a stamping die structure, and relates to the technical field of automobile design and manufacture. The stamping die structure comprises a pull rod bolt, an upper die base, a material pressing device, a pull rod bolt limiting structure and a trimming insert; the pressing device is matched with the trimming insert, the upper die base is arranged on the pressing device, a through bolt upper channel is arranged in the upper die base, a through bolt lower channel is arranged in the pressing device, the bolt lower channel is aligned with the bolt upper channel, and an internal cavity of the pressing device is communicated with the bolt lower channel; the bolt limiting structure is sleeved outside the pull rod bolt, and a cushion pad is arranged on the upper surface of the bolt limiting structure opposite to the upper wall of the inner cavity. The stamping die structure provided by the utility model has the advantages that the service life of the draw-bar bolt is prolonged, and the risk caused by the failure of the limit structure of the draw-bar bolt due to impact force in the stamping production process is avoided.
Description
Technical Field
The utility model relates to the technical field of automobile parts, in particular to a stamping die structure.
Background
In the prior art, the eccentric swage draw bar bolt structure directly acts on the draw bar bolt limiting surface, the connection of the type belongs to rigid contact, and in the long-term stamping process of a die, the reciprocating motion of the eccentric swage can cause the abrasion of the limiting end of the draw bar bolt, even the fracture failure caused by impact force is easy to occur, so that danger is easy to occur.
SUMMERY OF THE UTILITY MODEL
In order to solve the above technical problems in the prior art, the present invention provides a stamping die structure.
The stamping die structure comprises a pull rod bolt, an upper die base, a material pressing device, a pull rod bolt limiting structure and a trimming insert; the swaging device is matched with the trimming insert, the upper die base is arranged on the swaging device, a through bolt upper channel is arranged in the upper die base, a through bolt lower channel is arranged in the swaging device, the bolt lower channel is aligned with the bolt upper channel, and an internal cavity of the swaging device is communicated with the bolt lower channel; the bolt limiting structure is sleeved outside the pull rod bolt, and a cushion pad is arranged on the upper surface of the bolt limiting structure, which is opposite to the upper wall of the inner cavity.
The bolt limiting structure comprises a sleeve, and the sleeve is in threaded connection with the external thread of the pull rod bolt.
Wherein the cushion pad is a polyurethane cushion pad.
Compared with the prior art, the stamping die structure provided by the utility model has the following beneficial effects:
the stamping die structure provided by the utility model has the advantages that the service life of the draw-bar bolt is prolonged, and the risk caused by the failure of the limit structure of the draw-bar bolt due to impact force in the stamping production process is avoided.
Drawings
Fig. 1 is a schematic view of the structure of the stamping die of the present invention.
Detailed Description
The structure of the stamping die of the present invention will be further described with reference to specific embodiments to help those skilled in the art to more fully, accurately and deeply understand the technical solution of the present invention.
Example 1
As shown in fig. 1, the stamping die structure of the present embodiment includes a tie bolt 10, an upper die base 20, a swage 30, a tie bolt limiting structure 40, and a trimming insert 50. The swaging device 30 is matched with the trimming insert 50, the upper die holder 20 is arranged on the swaging device 30, a through bolt upper channel 21 is arranged in the upper die holder 20, a through bolt lower channel 31 is arranged in the swaging device 30, the bolt lower channel 31 is aligned with the bolt upper channel 21, and an internal cavity 32 of the swaging device 30 is communicated with the bolt lower channel 31. The bolt limiting structure 40 is sleeved outside the stay bolt 10, specifically, the bolt limiting structure 40 comprises a sleeve, and the sleeve is in threaded connection with the external thread of the stay bolt 10. A cushion 60, such as a polyurethane cushion, is provided on the upper surface of the bolt restraint structure 40 opposite the upper wall of the interior cavity 32.
Adopt the stamping die structure of this embodiment, normal during operation, the gravity action of eccentric swage 30 is on blotter 60, and the two flexonics has avoided eccentric swage gravity direct action on bolt limit structure 40, has avoided the production of impact force, has improved the life-span of stay bolt limit structure 40, can effectively prevent the risk hidden danger that leads to because of the stay bolt limit structure inefficacy in the stamping production.
It is obvious to those skilled in the art that the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the specific implementation of the present invention is not limited by the above-mentioned manner, and various insubstantial modifications made by the method concept and technical scheme of the present invention are within the protection scope of the present invention.
