Abstract

The utility model relates to a stamping die for removing sharp burrs. The stamping die for removing sharp burrs consists of a T-shaped movable module (1) and a fixed module (6). The movable module (1) is a whole composed of a die body and a cylindrical metal post (2). The root of the metal post (2) is a smooth arc-surface chamfer (3) formed by polishing. A concaved cylindrical space is arranged in the middle of the fixed module (6), and the diameter of the space equals to the diameter of the metal post (2). The height of the metal post (2) is bigger than the height of the fixed module (6). The patent of stamping dies for removing sharp burrs process improvement to the existed manner of removing burrs, the production cost is reduced, the integrate of removing burrs is achieved, and production efficiency is improved when remove burrs with the stamping die for removing burrs..

Description

Remove the diel of sharp burr

Technical field

The utility model relates to a kind of diel piece of removing sharp burr, belongs to electronic information field.

Background technology

Main line of current shunting is the tendency solution that present information electronic industry solves large electric current, the distribution of high reliability electric current.In actual application, main line of current shunting has a lot of holes, and these holes are to adopt digital stamping to produce, and will produce burr inevitably around these holes.These burrs must be removed, and the existence of burr affects the outward appearance of product on the one hand, and burr can because the existence of voltage causes point discharge, affect the normal use of main line of current shunting in the use procedure of main line of current shunting in addition.The way of before usually removing burr normally adopts artificial method that burr is polished off one by one, although this method is simple, but speed is slow, and the reason because of the people causes the polishing degree to be difficult to unification in the bruting process, and in the high enterprise of human cost and difficult today of recruiting, this method has exposed serious defective.

The utility model content

The purpose of utility model has provided a kind of diel piece of removing sharp burr, by designing corresponding dynamic model piece and cover half piece, utilizes arc surface and extruding to get rid of burr, and efficient is high, and effect is good.

In order to reach above-mentioned utility model purpose, the technical scheme that the utility model adopts is:

A kind of diel piece of removing sharp burr is comprised of T-shaped dynamic model piece and cover half piece, and the dynamic model piece is made of die body and cylindrical metal post one, and the root polishing of metal column forms smooth arc surface chamfering.

Preferably, above-mentioned cover half piece intermediate recess has cylindrical space, and the diameter in space equals the diameter of metal column.

Preferably, the height of above-mentioned metal column is greater than the height of cover half piece.

Compared with prior art, the utility model patent is improved for the method for removing burr that adopts before, adopts a kind of diel to go the processing of burr, successfully will reduce production cost, has realized going the unified degree of burr, has improved production efficiency.

The specific embodiment

Understand and enforcement the utility model for the ease of those of ordinary skills, below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.

Shown in Fig. 1-4, the diel of the removal main line of current shunting burr that the utility model provides is comprised of T-shaped dynamic model piece 1 and cover half piece 6.As shown in Figure 1, dynamic model piece 1 is made of die body and cylindrical metal post 2 one, and the root polishing of metal column 2 forms smooth arc surface chamfering 3.As shown in Figure 2, main line of current shunting 5 is fixed on the cover half piece 6, and the burr 4 at hole edge is not yet removed.As shown in Figure 3, shown the state behind the dynamic model piece 1 and cover half piece 6 matched moulds in the punching course, as seen from the figure, burr 4 arc surface chamfering 3 extruding of passive module 1 is removed.As shown in Figure 4, after dynamic model piece 1 and cover half piece 6 separated in the punching course, the burr 4 at punching course Hole edge was squeezed equably by metal column 3 and removes, and reaches the effect of removing burr.

Can draw from figure, cover half piece 6 intermediate recess have cylindrical space, and the diameter that the diameter in space equals metal column 2 just can reach good squeezing effect, can the Liu Chu space.And burr 4 itself has certain thickness, and therefore, the height of metal column 2 is greater than the height of cover half piece 6.The key position that the dynamic model piece 1 of whole stamping die is removed burr is stamped metal post 3, the structure of these metal columns is very simple, utilize the more characteristic of stiffened of the relative copper material of steel, in punching course, utilize circular arc 2 parts of metal column bottom that the burr at hole edge is removed.

The diel piece of the removal point burr that the utility model provides, dynamic model piece and cover half piece part have been designed, cover half piece fixed current distributing main line, the dynamic model piece utilizes the arc surface chamfering to squeeze burr in the process of punching press, this mould that can batch type operates has reduced the production cost of removing main line of current shunting surface burr, improve productivity ratio, reduced number of workers and the uniformity that has realized product.

The above, only be that implementation case of the present utility model is described, but be not to limit practical range of the present utility model, such as those skilled in the art must be covered by the scope of the utility model claim not breaking away from all equivalence changes of finishing under the indicated spirit of the utility model and the principle or modifying.
