The band bending is towards the diel of part
The utility model relates to a kind of diel, particularly a kind of have bending towards part diel.
Diel is called for short stamping machine, claims forcing press again, is material is carried out the equipment that pressure processing is used.Its operation principle generally is to drive the folding of patrix and counterdie and setting such as raw material between with it cut, punching, stretching under the effect of punching press power by mould, forms stamping parts.According to the operation principle of forcing press, can be divided into mechanical press and hydraulic press.Mechanical press is to finish punching course by the Motor Drive slide block movement; Hydraulic press is by hydraulic principle, drives the reciprocating motion of hydraulic pressure steel and finishes punching course.Mechanical press work reciprocating frequence is fast, speed height, efficient height, but the power that produces is less, generally is used for mini-type punching equipment, and punching, shearing technology.The force rate that the hydraulic pressure function produces is bigger, but speed is slower, generally is used for stretching, moulding production, also is used for the punching press and the shearing of heavy parts.
Existing stamping machine is when carrying out the process of punching, general can only shear at stamping machine, punching, operations such as stretching, and in a lot of occasions, again to these through shearing, punching press, stamping parts after operations such as stretching are finished also will bend according to the actual needs of product, so that reach the designing requirement of product, therefore existing diel often just can not be satisfied above-mentioned requirement, therefore must to carry out punching press to product earlier at every turn, take out separately again after to be punched the finishing and bend operation, troublesome poeration so not only, and because therefore many one operational sequences tend to waste the more time, production efficiency is low, and production cost is higher.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of stamping machine of new structure, and this diel is provided with a bending towards part, can bend stamping parts towards part by this bending.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of with the diel of bending towards part, comprise drive unit, upper die and lower die, described drive unit is connected with described patrix, described patrix is positioned at the top of described counterdie, described patrix is provided with at least one bending towards part, and described bending is provided with the arc convex that is used to bend stamping parts towards the lower end of part.
Preferably, comprise two bendings towards part, described two bendings are towards the part symmetric arrays.
Preferably, described bending also is connected with the limit for height post towards the part lower end.
Preferably, also be provided with on the described patrix and cut off the cutting off of stamping parts towards part.
Technique scheme has following beneficial effect: in this scheme, the patrix of stamping machine is provided with bending towards part, bending is provided with the arc convex that is used to bend stamping parts towards the lower end of part, when stamping machine is worked, when carrying out punching press, can bend stamping parts like this by the arc-shaped protrusions of bending towards part, stamping parts is promptly plastic through one-shot like this, need repeatedly not process, save the time, improve operating efficiency.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of the utility model embodiment bending towards part.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, this diel comprises drive unit, patrix 1 and counterdie 2, patrix 1 is connected (not shown) with drive unit, patrix 1 is positioned at the top of counterdie 2, patrix 1 is provided with two symmetrical mutually bendings towards part 3, bending is provided with the arc convex 31 (as shown in Figure 2) that is used to bend stamping parts towards the lower end of part 3, and bending also is provided with towards the lower end of part 3 and can be used for spacing limit for height post 5.Also be provided with on the patrix 1 and be used to cut off the cutting off of stamping parts towards part 4.
During this diel work, at first move downward and push down the product 6 that needs punching press by drive unit driving patrix 1, then this product is carried out punching press, when carrying out punching press, bending needs the part of bending to bend through arc convex 31 towards part to product 6, after cut off towards part the product that processes is cut off, product 6 just can one-shot forming so.Reduce operating procedure, saved the operating time, improved operating efficiency.
More than to a kind ofly being described in detail that the utility model embodiment is provided with the diel of bending towards part; for one of ordinary skill in the art; thought according to the utility model embodiment; part in specific embodiments and applications all can change; therefore this description should not be construed as restriction of the present utility model, and all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
