Specific embodiment

In order to make those skilled in the art more fully understand the technical solution of the present embodiment, with reference to the accompanying drawing and pass through tool Body embodiment further illustrates the technical solution of the present embodiment.

In the description of the present invention, it should be noted that term " on ", "lower", "left", "right", "vertical", " water It is flat ", "inner", the instructions such as "outside" orientation or positional relationship be to be based on the orientation or positional relationship shown in the drawings or this product The orientation or positional relationship usually put when use is merely for convenience of description the utility model, rather than indication or suggestion institute The device or element of finger must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this reality With novel limitation.

Existing display backplane is mostly sheet metal component, it usually needs carries out four sides bending technique, at present bending to sheet metal component Technique is mainly bilateral molding, and four sides bending then needs to carry out bilateral bending twice, be easy to cause produce discontinuous, work in this way Make the problems such as efficiency is lower.

Fig. 1 is the top view for the sheet metal component 200 processed in the present embodiment, and specific processing technology is, to metal plate Four sides of part 200 carry out bending simultaneously.

To solve the above-mentioned problems, as shown in figures 2-6, a kind of four sides Bending Mould 100 is present embodiments provided, including with In the upper mold group and lower die group of molding sheet metal component 200, wherein upper mold group includes upper clamp plate 1 and is arranged in convex on upper clamp plate 1 Mould 2, lower die group include lower clamp plate 5 and the lower cavity die 4 that is arranged on lower clamp plate 5, and lower cavity die 4 can be matched with upper male mould 2；Under Cavity plate 4 includes the first piece 41, the second piece 42, third piece 43 and the 4th piece 44, in the present embodiment, the first piece 41, the 44 rectangular cavity plate of splicing group of the second piece 42, third piece 43 and the 4th piece, so that lower cavity die 4 can be with upper male mould 2 It matches.In addition, being provided with beading formed punch 3 on upper male mould 2, the first piece 41, the second piece 42, third piece 43 and the 4th are spelled Beading groove 45 is provided on the position opposite with beading formed punch 3 of block 44, beading formed punch 3 can be matched with beading groove 45, The intensity of bending part can be improved to improve the stability of bending part in 200 bending part molding strengthening ribs of sheet metal component. Four sides Bending Mould 100 provided in this embodiment can be achieved at the same time four sides bending technique, and can enhance the strong of bending part Degree greatlys save time and cost while guaranteeing quality.

In addition, as shown in Fig. 2, four sides Bending Mould 100 provided in this embodiment further includes guidance set 7, including match The guide post and sleeve of conjunction, one in the two is arranged in upper mold group, another is arranged in lower die group.In the present embodiment, Guide post is arranged on upper male mould 2, and sleeve is arranged on lower cavity die 4, and guide post can be moved up and down along sleeve, on the one hand make upper male mould 2 can move up and down along sleeve, on the other hand make the up and down motion of upper male mould 2 more steady, to improve processing quality.At other In embodiment, it can also be that sleeve is arranged on upper male mould 2, guide post is arranged on lower cavity die 4, and guide post can move down along sleeve It is dynamic, also it is able to achieve said effect.

Specifically, in the present embodiment, the diameter of guide post is 20mm, and the length of guide post is 80mm, and guide post must be Punch die precision guide post.The quantity of guide post is 4, the quadrangle of upper male mould 2 is arranged in, preferably to support upper male mould 2.

Illustratively, as shown in figure 4, offering bending step along 41 length direction of the first piece, the setting of bending step In the side opposite with beading groove 45, further bending is carried out so as to the outer edge to sheet metal component 200, it is more to form A bending part improves working efficiency.
