Abstract
The utility model discloses a stamping and pre-breaking structure which comprises a bearing part and a forming part, a connecting part is integrally arranged between the bearing part and the forming part, a pre-breaking mark is arranged on the connecting part and is arranged at a place where the connecting part is connected with the forming part, and the depth of the pre-breaking mark is 1/3-1/2 of thickness of the connecting part. Through arranging the pre-breaking mark, when a material belt is bent, the forming part and the bearing part can be easily broken by a stamping machine without causing burrs and broken marks and influencing appeanrce and functions, is suitable for mass production, and can improve production efficiency.
Description
Technical field
The utility model relates to a kind of punching press pre-cutting structure.
Background technology
Existing impact style is that forming part and supporting part are directly fractureed; produce burr, slight crack at the cracking-off supporting part at the place of fractureing by often meeting; can affect the outward appearance of product; more serious; can affect the function of product; cause the subsequent treatment of product cumbersomely, increased operating personnel's workload, thereby reduced production efficiency.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of difficult affect product appearance with and the punching press pre-cutting structure of function.
The technical solution of the utility model is achieved in that a kind of punching press pre-cutting structure, it comprises supporting part, forming part, be integrally formed with connecting portion between described supporting part and the forming part, described connecting portion is provided with pre-mark of break, described pre-mark of break is positioned at the connecting position of described connecting portion and described forming part, the degree of depth of described pre-mark of break be connecting portion thickness 1/3 to 1/2.
Preferably, be integrally formed with a plurality of connecting portions between described supporting part and the forming part, at least one connecting portion is provided with described pre-mark of break.
The utility model has the advantages that: by the setting of pre-mark of break, when the bending strip, forming part and supporting part are easy to the machine of being stamped and fracture, and the trace that ruptures burr can not appear and, do not affect outward appearance and the function of product, be applicable to batch production, and improved production efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not consist of any restriction of the present utility model.
Fig. 1 is the structural representation of the present embodiment;
Fig. 2 is the structural representation after the punching press pre-cutting structure of the present embodiment is passed through punching press;
Fig. 3 is the partial enlarged drawing at A place among Fig. 2.
Among the figure:
The 1-supporting part; The 2-forming part; The 3-connecting portion; The pre-mark of break of 4-.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
Consult shown in Figure 1, the punching press pre-cutting structure of the present embodiment, it comprises supporting part 1, forming part 2, be integrally formed with connecting portion 3 between supporting part 1 and the forming part 2, connecting portion 3 is provided with pre-mark of break 4, pre-mark of break 4 is positioned at the connecting position of connecting portion 3 and forming part 2, wherein, the degree of depth of pre-mark of break 4 be connecting portion 3 thickness 1/3 to 1/2.
Be integrally formed with a plurality of connecting portions 3 between supporting part 1 and the forming part 2, at least one connecting portion 3 is provided with pre-mark of break 4, is provided with two connecting portions 3 between the supporting part 1 in the present embodiment and the forming part 2, is equipped with pre-mark of break 4 on each connecting portion 3.
Such as Fig. 2, shown in Figure 3, at first be under pressure through the pre-mark of break 4 on the connecting portion 3 after the stamping machine punching press, supporting part 1 at first misplaces along pre-mark of break 4 with forming part 2, and namely forming part 2 can be stepped with the lateral section of connecting portion 3 joints, then is easy to realize the work that fractures.
Above embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the people that is familiar with technique understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
Claims (2)
