Abstract

The invention provides an annular cutting and deburring die device, which comprises an upper template and a lower template, wherein the upper template is suspended directly above the lower template, and a male die is arranged on the lower template; a transmission mechanism is arranged below the upper template, and a female die is arranged below the transmission mechanism; an inwardly inclined cutting edge is arranged on the lower edge of the female die. Through the special processing of an ordinary annular cutting die, a novel process that burrs are prevented from being generated while the shape is cut off is provided. After the annularly cut and deburred product is added to be subjected to extrusion and deformation when the outer edge is cut off, the section of the final product has an C-corner effect, the section is smooth, and the deburring and the cutting are simultaneously carried out, so the working efficiency is improved.

Description

[0001] technical field [0002] The invention relates to a ring cutting and grinding device. [0003] Background technique [0004] The punching die is to bend the blade into the required shape, and "cut" the sheet through the punching or pressing equipment to obtain the product. The punching die device is exactly the stamping equipment. In the prior art, the punching die device includes an upper template and a lower template adapted to each other, the upper template and the lower template cooperate through guide posts and guide holes, and a single-piece cutter is provided on the upper template. Traditional shape punching needs to be carried out in sections, the process is cumbersome, and there will be unevenness and burrs on the cut surface of the shape. [0005] Patent document CN203002903U mentions "a punching die", which includes an upper die and a lower die. The upper die includes a punch and several guide sleeves arranged on the lower side of the upper die. Side fl...
