Abstract
The utility model relates to a stamping die for removing current shunt mainline burrs, which comprises a T-shaped movable die (1) and a fixed die (6). The movable die (1) consists of a die body and a cylindrical steel column (2) in integration; the root of the steel column (2) is polished into a smooth arc chamfer angle (3); a cylindrical space is recessed in the middle of the fixed die (6); the diameter of the space is equal to that of the steel column (2); and the height of the steel column (2) is larger than that of the fixed die (6). A past burr removing method is improved, the stamping die is used for removing the burrs, production cost is reduced successfully, uniformity of burr removal is realized, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of diel that electric current shunting main line is criticized cutting edge of a knife or a sword of removing, and belongs to electronic information field.
Background technology
Electric current shunting main line is the tendency solution that present information electron trade solves big electric current, the distribution of high reliability electric current.In actual application, electric current shunting main line 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 influences the outward appearance of product on the one hand, and burr can influence the normal use of electric current shunting main line because the existence of voltage causes point discharge in the use of electric current shunting main line in addition.The way of before removing burr usually normally adopts artificial method that burr is polished off one by one, though 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 that electric current shunting main line is criticized cutting edge of a knife or a sword of removing, and by designing corresponding dynamic model and cover half, utilizes arc surface and extruding to get rid of burr, the efficient height, and effect is good.
In order to reach above-mentioned utility model purpose, the technical scheme that the utility model adopted is:
A kind of electric current of removing is shunted the diel that main line is criticized cutting edge of a knife or a sword, is made up of T type dynamic model and cover half, and dynamic model is made of die body and cylindrical steel column one, and the root polishing of steel column forms smooth arc surface chamfering.
Preferably, above-mentioned cover half intermediate recess has cylindrical space, and the diameter in space equals the diameter of steel column.
Preferably, the height of above-mentioned steel column is greater than the height of cover half.
Compared with prior art, the utility model patent is improved at 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, the utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
Shown in Fig. 1-4, the diel of the removal electric current shunting main line burr that the utility model provides is made up of T type dynamic model 1 and cover half 6.As shown in Figure 1, dynamic model 1 is made of die body and cylindrical steel column 2 one, and the root polishing of steel column 2 forms smooth arc surface chamfering 3.As shown in Figure 2, electric current shunting main line 5 is fixed on the cover half 6, and the burr 4 at hole edge is not removed as yet.As shown in Figure 3, shown the state behind the dynamic model 1 and cover half 6 matched moulds in the punching course, as seen from the figure, burr 4 is removed by arc surface chamfering 3 extruding of dynamic model 1.As shown in Figure 4, after dynamic model 1 and cover half 6 separated in the punching course, the burr 4 at hole edge was squeezed equably by steel column 3 and removes in the punching course, reaches the effect of removing burr.
Can draw from figure, cover half 6 intermediate recess have cylindrical space, and the diameter that the diameter in space equals steel 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 steel column 2 is greater than the height of cover half 6.The key position that the dynamic model 1 of whole stamping die is removed burr is a punching press steel column 3, and the structure of these steel columns is very simple, utilizes the more characteristic of stiffened of the relative copper material of steel, utilizes circular arc 2 parts of steel column bottom that the burr at hole edge is removed in punching course.
The removal electric current shunting main line that the utility model provides is criticized the diel of cutting edge of a knife or a sword, dynamic model and cover half part have been designed, cover half fixed current shunting main line, dynamic model utilizes the arc surface chamfering to squeeze burr in the process of punching press, this mould of can batch type operating has reduced the production cost of removing electric current shunting main line surface burr, improved productivity ratio, reduced number of workers and realized consistency of product.
The above, only be in order to concrete case study on implementation of the present utility model to be described, but be not in order 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 being finished under indicated spirit of the utility model and the principle or modifying.
Claims (3)
1. remove the diel that electric current shunting main line is criticized cutting edge of a knife or a sword for one kind, form by T type dynamic model (1) and cover half (6), it is characterized in that: dynamic model (1) is made of die body and cylindrical steel column (2) one, and the root polishing of steel column (2) forms smooth arc surface chamfering (3).
