Abstract
The utility model discloses a kind of hollow type sheet stamping die structure, comprise upper die and lower die, described patrix is provided with standard punch, and described counterdie is provided with punch die material-dropping hole, described standard punch is provided with hollow out cell body, and described standard punch is in the random uniform balance distribution of patrix.When the utility model carries out punching press, hollow out in the middle of standard punch, the a bit of participation compacting in marginal portion is only had to contact punching press with drawing quality steel sheet, less with the area of sheet contacts, thin plate compressive deformation is little, ram ratio comparatively steadily balanced, save stamping press, the defect such as to weigh, damaged surfaces, surface abnormalities, surface adhesion force are not enough after avoiding and decrease a large amount of punch dies wounded, significantly improve punching press yields and punching press economic benefit.
Description
Technical field
The utility model relates to sheet stamping forming field, is specifically related to a kind of hollow type sheet stamping die structure.
Background technology
In existing punch die manufacturing technology, thin plate punching is completed by common flat plate mold, and its product quality can not get management and control, and disqualification rate is more, and after punching press, sheet stamping product often occurs that product weighs wounded, damages, the bad phenomenon such as surface abnormalities.
Utility model content
The purpose of this utility model is the above problem overcoming prior art existence, a kind of hollow type sheet stamping die structure is provided, when the utility model carries out punching press, hollow out in the middle of standard punch, the a bit of participation compacting in marginal portion is only had to contact punching press with drawing quality steel sheet, less with the area of sheet contacts, thin plate compressive deformation is little, ram ratio is balanced, saving stamping press comparatively steadily, the defect such as to weigh, damaged surfaces, surface abnormalities, surface adhesion force are not enough after avoiding and decrease a large amount of punch dies wounded, significantly improve punching press yields and punching press economic benefit.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of hollow type sheet stamping die structure, comprise upper die and lower die, described patrix is provided with standard punch, described counterdie is provided with punch die material-dropping hole, described standard punch is provided with hollow out cell body, described standard punch is in the distribution of patrix random uniform balance, and thin plate to be thickness be 0.5-1.8mm's can pressing sheet material.
Further, the hollow out cell body hollow out degree of depth that described standard punch is arranged is 0.15-0.2 mm.
Further, the Edge Distance of the Edge Distance standard punch of the hollow out cell body of described setting is 0.5-3 mm.
The beneficial effects of the utility model are:
When the utility model carries out punching press, hollow out in the middle of standard punch, the a bit of participation compacting in marginal portion is only had to contact punching press with drawing quality steel sheet, less with the area of sheet contacts, thin plate compressive deformation is little, ram ratio comparatively steadily balanced, save stamping press, the defect such as to weigh, damaged surfaces, surface abnormalities, surface adhesion force are not enough after avoiding and decrease a large amount of punch dies wounded, significantly improve punching press yields and punching press economic benefit.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is overall structure schematic diagram of the present utility model.
Number in the figure illustrates: 1, patrix, 2, counterdie, 3, standard punch, 4, hollow out cell body, 5, punch die material-dropping hole.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Fig. 1, a kind of hollow type sheet stamping die structure, comprise patrix 1 and counterdie 2, described patrix 1 is provided with standard punch 4, described counterdie 2 is provided with punch die material-dropping hole 8, described standard punch 4 is provided with hollow out cell body 7, and described standard punch 4 is in the random uniform balance distribution of patrix 1, and thin plate to be thickness be 0.5-1.8mm's can pressing sheet material.
Further, the hollow out cell body 4 hollow out degree of depth that described standard punch 3 is arranged is 0.15-0.2 mm.
Further, the Edge Distance of the Edge Distance standard punch 3 of the hollow out cell body 4 of described setting is 0.5-3 mm.
The operation principle of the present embodiment is as follows:
When making patrix of the present utility model, the end face of all standard punch 4 has all carried out hollow out and has added groove, and the degree of depth of hollow out is between 0.15-0.2 mm, and the Edge Distance of criterion distance drift 3 is 0.5-3 mm.Counterdie of the present utility model is identical with the structure of common diel, when punching press, hollow out in the middle of standard punch, the a bit of participation compacting in marginal portion is only had to contact punching press with drawing quality steel sheet, less with the area of sheet contacts, thin plate compressive deformation is little, and ram ratio is balanced, saving stamping press comparatively steadily, the defect such as to weigh, damaged surfaces, surface abnormalities, surface adhesion force are not enough after avoiding and decrease a large amount of punch dies wounded, significantly improve punching press yields and punching press economic benefit.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
