A kind of door plate hinge die punching structure

Technical field：

This practicality is related to a kind of die punching structure, more particularly to a kind of door plate hinge die punching structure, belongs to machinery Equipment technical field.

Background technology：

Hinge is also known as hinge, is for connection to two solids and allows the mechanical device to rotate between the two.Hinge can It can be made of moveable component or be made of folding material.Flap is usually stamping parts, by press machine punching press It is made, generally the front end of one block of long and narrow plate to be punched is placed at by press machine workbench using continuous punching during production Lower mold in, moved by mold relative lower dies and complete punching press, the good hinge of punching press is taken out, continues to move to plate to be punched The i.e. lower mold in front end to operating position in, punching press again, and so on, a long and narrow sheet forming is gradually gone out into multiple hinges Carrier bar.The problem is that needing operating personnel that plate to be punched is moved to operating position manually, control accuracy is not high, raw simultaneously It is low to produce efficiency.

Utility model content：

The purpose of the utility model is to overcome in place of the deficiencies in the prior art, a kind of door plate hinge die punching knot is provided Structure, can disposable punching, from error caused by secondary punching, scale is more accurate, wherein cut mold with 4 guide posts, grinds Tool is more more stable durable, solves the problems of the prior art.

To achieve the above object, the utility model provides following technical solution：A kind of door plate hinge die punching structure, packet Back-pressure side plate is included, is distributed in four guide posts in lower mold, the upper mold seat moved up and down along ram axle, ram axle, guide plate, lower die Seat, workbench, punching press machine base, lower mold, the back-pressure side plate are mounted in ram axle, are the parts of single load bearing；It is described It is fixed on back-pressure side plate along the upper mold seat that ram axle moves up and down, is moved up and down with back-pressure side plate stress；The ram axle is consolidated It is scheduled on punching press machine base, accurate guiding is provided for upper and lower die holder；The guide plate is in die holder die surface, guarantee upper and lower mould Tool is mutually aligned, while takes out the blank that punching terminates；The die holder, inside have four guide posts, the workbench is located at On punching press machine base, die holder support；The lower mold is fixed in die holder, there is all holes that hinge needs rush on mold Mouthful.

Preferably, there are all apertures that hinge needs punching on the lower mold.

Preferably, there are four cutting guide posts in the lower mold.

Compared with prior art, the beneficial effects of the utility model are as follows：A kind of door plate hinge die punching structure, upper mold Seat is fixed in back-pressure side plate, and back-pressure side plate by being moved up and down after ram axle stress, fix on the table by die holder, it is impossible to It moves up and down, the mold in die holder, there is all holes of hinge punching, convenient for one-off hole-piercing, its internal distribution four in addition is led very much Column, in the case of the pressure by upper mold seat, uniform force will not cause die holder stress to shift.

Description of the drawings：

Fig. 1 is a kind of door plate hinge die punching structure diagram of the utility model；

Fig. 2 is a kind of door plate hinge die punching structure sectional view of the utility model.

Figure label:1 be back-pressure side plate, 2 be in the lower mold of distribution four guide posts, 3 be moved up and down along ram axle it is upper Die holder, 4 be ram axle, 5 be guide plate, 6 be die holder, 7 be workbench, 8 be punching machine base, 9 be lower mold.

Specific embodiment：

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained shall fall within the protection scope of the present invention.

Please refer to Fig.1-2, a kind of door plate hinge die punching structure, four guide posts 2 in back-pressure side plate 1, the lower mold of distribution, Upper mold seat 3, ram axle 4, guide plate 5, die holder 6, workbench 7, punching machine base 8, the lower mold 9 moved up and down along ram axle, Back-pressure side plate 1 is mounted in ram axle 4, is the part of single load bearing；The upper mold seat 3 moved up and down along ram axle is fixed on back-pressure On side plate 1, moved up and down with 1 stress of back-pressure side plate；Ram axle 4 is fixed on punching press machine base 8, and precision is provided for upper and lower die holder Guiding；Guide plate 5 ensures that upper/lower die is mutually aligned, while take out the blank that punching terminates in 6 die surface of die holder；Under Die holder 6 has four guide posts 2 inside it, and workbench 7 is located on punching press machine base 8, supports die holder；Lower mold is fixed on lower die In seat 6, disposable punching is convenient in all apertures that having hinge on mold needs punching.

In summary：A kind of door plate hinge die punching structure when blank is placed in lower mold, has four in lower mold Guide post, correspondence want hole punched, when back-pressure side plate 1 is by pressure, is downwardly oriented and moves along ram axle, the mold in upper mold seat Veneer is touched, is continued to move to downwards along guide plate 5, after upper/lower die contact, the continuation stress of back-pressure side plate 1, and the four of lower mold Root guide post starts to cut hinge blank, while uniform force, does not complete all punchings only once, while improve safety, makes mould Have more stable durable.

The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession The technical staff of industry is described in the above embodiment and specification it should be appreciated that the utility model is not limited by above-mentioned implementation 1 Only illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model can also There are various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The utility model will Protection domain is asked to be defined by the appending claims and its equivalent thereof.
