Description

Extrusion Burr Die

technical field

The utility model relates to the technical field of molds, in particular to an extrusion burr mold.

Background technique

In the processing of metal products, die stamping is mostly used to complete the punching of the shape, but the shape of the product stamped by conventional dies always has burrs, which cannot be removed. Small parts can be removed by grinding and corrosion processes, and large parts cannot be processed. For this reason, only The traditional manual grinding method can be used to remove burrs, which is not only cumbersome to operate, but also has low work efficiency and high work intensity.

Utility model content

In view of the above shortcomings, the purpose of this utility model is to provide an extrusion burr die with ingenious and reasonable structural design, which can effectively reduce the scratches on the product surface.

In order to achieve the above purpose, the technical solution provided by the utility model is: an extrusion burr mold, which includes an upper mold base, an upper backing plate, an upper template, a lower template, a lower backing plate, a lower mold base, a lower pad and a lower The supporting plate, the upper mold base, the upper backing plate and the upper formwork are stacked in order from bottom to top to form the upper mold group, and the lower formwork, lower backing plate, lower mold base, lower feet and lower supporting plate are stacked in order from bottom to top The upper die set and the lower die set are matched through the guide column assembly; the surface of the lower die plate opposite to the upper die set is provided with a cavity matching the contour of the workpiece. The side wall is arranged at an inclination angle a, and the inclination angle a is 84-86 degrees; the corners of the cavity are rounded with a radius of 0.5 mm.

As an improvement of the utility model, the inclination angle a is 85 degrees.

As an improvement of the present utility model, the guide column assembly includes a guide column and a guide sleeve adapted to the guide column, the guide column is vertically arranged on the lower mold base, and the guide sleeve is fixed on the upper mold base , and set on the guide column.

The beneficial effects of the utility model are: the utility model has an ingenious and reasonable structural design, puts the workpiece to be deburred into the cavity of the lower template, and then squeezes the workpiece through the upper template to make the burr of the workpiece become Smooth R angle, so as to achieve the purpose of deburring, high production efficiency, low cost, and very little product deformation, can meet the deburring requirements of high-precision products, greatly improve work efficiency, and ensure product quality, which is conducive to widespread promotion application.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

Detailed ways

Referring to Fig. 1 and Fig. 2, a kind of extruding burr mold provided in this embodiment comprises an upper mold base 1, an upper backing plate 2, an upper template 3, a lower template 4, a lower backing plate 5, a lower mold base 6, a lower Feet 7 and lower supporting plate 8, upper mold base 1, upper backing plate 2 and upper formwork 3 are stacked in order from bottom to top to form an upper mold group, lower formwork 4, lower backing plate 5, lower mold base 6, and lower footing 7 and the lower supporting plate 8 are sequentially stacked from bottom to top to form a lower die set, and the upper die set and the lower die set are matched through the guide post assembly 9; There is a cavity 41 matching the outline of the workpiece 10, the side wall of the cavity 41 is set at an inclination angle a, and the inclination angle a is 84 to 86 degrees; the corners of the cavity 41 are provided with a radius The round corners R1 and R2 are 0.5mm. Preferably, the inclination angle a is preferably 85 degrees.

Specifically, the guide column assembly includes a guide column and a guide sleeve adapted to the guide column, the guide column is vertically arranged on the lower mold base 6, the guide sleeve is fixed on the upper mold base 1, and is sleeved on the guide post.

When working, put the workpiece 10 that needs to be deburred into the cavity 41 of the lower template 4, and then squeeze the workpiece 10 through the upper template 3 at one time, so that the burrs of the workpiece 10 become smooth R angles, thereby realizing removal The purpose of deburring is high production efficiency, low cost, and very little product deformation, which can meet the deburring requirements of high-precision products, greatly improve work efficiency, and ensure product quality.

According to the disclosure and teaching of the above specification, those skilled in the art to which the present utility model belongs can also change and modify the above embodiment. Therefore, the utility model is not limited to the specific implementation manners disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model.
