Description

A kind of cupping tool

Technical field

This utility model is related to five metals thin plate processing technique field and in particular to a kind of cupping tool.

Background technology

Five metals thin plate this kind of five metals thin plate is in the operation of raising bag, downward because being acted on by the downward cold-stamped of pressure head Drawing, five metals thin sheet surface is formed the convex closure of certain depth by the position of drawing, and in drawing process, five metals thin sheet surface is drawn The material of deep position can flow, thus producing tension force, in the intersection of convex closure and five metals thin sheet surface, this tension force is particularly bright Aobvious, the convex closure in five metals thin plate is generally 3mm-1m by the depth of drawing, and the depth of convex closure is deeper, and the tension force of generation is bigger, example As the shell on the back of cathode ray tube display, its convex closure needs drawing to 1m, thus the tension force producing is particularly evident, and this tension force leads to Five metals thin plate sticks up distortion or concavo-convex arch camber out-of-flatness in this intersection.

Utility model content

In place of the purpose of this utility model is for the deficiencies in the prior art, and provide a kind of cupping tool so that making More smooth for the five metals thin sheet surface going out.

For achieving the above object, this utility model provides a kind of cupping tool, and including upper bolster and die shoe, upper bolster sets It is equipped with the pressure head for punching press five metals thin plate, die shoe is provided with the lower template for bearing five metals thin plate, the lower end tool of pressure head There is protuberance, the upper end of lower template has the groove adaptable with the shape of protuberance, and pressure head is to thin in five metals during five metals sheet stamping Plate surface forms convex closure, and outside pressure head, corresponding convex closure is provided with for entering to intersection with the position of the intersection of five metals thin sheet surface The flat configuration of the smooth process of row.

Wherein, described flat configuration includes smooth piece and for intersection carried out with the step of smooth process, step located at Smooth piece of bottom.

Wherein, described shoulder height is set to 0.2-0.5mm.

Wherein, described shoulder height is set to 0.3mm.

Wherein, flat configuration includes smooth piece and for intersection carried out with the wedge of smooth process, wedge located at Smooth piece of bottom.

Wherein, cupping tool also includes the fixed block for fixing five metals thin plate, and fixed block is fixedly connected on upper bolster Lower surface.

The beneficial effects of the utility model:

A kind of cupping tool of the present utility model, five metals thin plate is delivered in lower template, under extraneous downward power, on The whole structure of die holder band dynamic head peace moves down, and five metals thin plate is pressed in the groove of lower template the protuberance of pressure head, thus Five metals thin sheet surface forms a convex closure, and simultaneously or subsequently, flat configuration is entered to the intersection of convex closure and five metals thin sheet surface Row shear extrusion, thus eliminating intersection due to the flowing of material and the tension force that produces during drawing, effectively prevent this intersection Produce distortion or uneven whole so that processing after five metals thin sheet surface more smooth.

Brief description

Using accompanying drawing, the utility model is described in further detail, but the embodiment in accompanying drawing is not constituted to of the present utility model Any restriction, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to following attached Figure obtains other accompanying drawings.

Fig. 1 is a kind of generalized section of cupping tool of this utility model.

Specific embodiment

Below in conjunction with specific embodiment and accompanying drawing, this utility model is described in detail.

A kind of specific embodiment of cupping tool of the present utility model, as shown in figure 1, include upper bolster 1 and die shoe 4, upper bolster 1 is provided with the pressure head 2 for punching press five metals thin plate 7, and die shoe 4 is provided with the lower mould for bearing five metals thin plate 7 Plate 3, the lower end of pressure head 2 has protuberance (figure is not marked), and the upper end of lower template 3 has the groove (figure adaptable with the shape of protuberance Do not mark), pressure head 2 forms convex closure to during five metals thin plate 7 punching press on five metals thin plate 7 surface, and the corresponding convex closure in pressure head 2 outside is thin with five metals The position of the intersection on plate 7 surface is provided with the flat configuration for intersection is carried out with smooth process.

During use: five metals thin plate 7 is delivered in lower template 3, under extraneous downward power, upper bolster 1 carries dynamic head 2 He Flat configuration moves down, and five metals thin plate 7 is pressed in the groove of lower template 3 protuberance of pressure head 2, thus in five metals thin plate 7 table Face forms a convex closure, and simultaneously or subsequently, flat configuration carries out shearing and squeezes to the intersection of convex closure and five metals thin plate 7 surface Pressure, thus eliminating intersection due to the flowing of material and the tension force that produces during drawing, effectively prevent this intersection and producing distortion Or uneven whole so that processing after five metals thin plate 7 surface more smooth.

Specifically, as shown in Fig. 2 flat configuration includes smooth piece 5 and for intersection is carried out with the step of smooth process 51, step 51 is located at smooth piece 5 of bottom.

In order to adapt to the five metals thin plate 7 of different-thickness, the height of step 51 is set to 0.2-0.5mm.Using this height Step 51 carry out shear extrusion process when, can make to be extruded the thickness of 0.2-0.5mm positioned at five metals thin plate 7 surface of intersection Degree is such that it is able to preferably eliminate the tension force of this intersection, it is to avoid five metals thin plate 7 produces distortion or uneven whole.

Preferably, the height of step 51 is set to 0.3mm.

As shown in figure 3, another embodiment of flat configuration, including smooth piece 5 with for smooth place is carried out to intersection The wedge 52 of reason, wedge 52 is located at smooth piece 5 of bottom.

In order to prevent five metals thin plate 7 two ends from sticking up, also include the fixed block 6 for fixing five metals thin plate 7, fixed block 6 It is fixedly connected on the lower end of upper bolster 1.

For reduces cost, the side of smooth piece 5 lower surface being fixedly connected on upper bolster 1 or pressure head 2.

For reduces cost, the lower end of upper bolster 1 is fixedly connected with pressure head 2, and the upper end of die shoe 4 is fixing with lower template 3 Connect.

Finally it should be noted that above example is only in order to illustrating the technical solution of the utility model, rather than to this reality With the restriction of novel protected scope, although having made to explain to this utility model with reference to preferred embodiment, this area general Lead to it will be appreciated by the skilled person that the technical solution of the utility model can be modified or equivalent, without deviating from this The spirit and scope of utility model technical scheme.
