Description

A kind of for processing the drift of clutch shell fragment

Technical field

The utility model relates to blanking die, is specifically related to a kind of for processing the drift of clutch shell fragment.

Background technology

Stamping-out clutch shell fragment needs special drift, Fig. 5 is the structure of the drift of clutch shell fragment blanking die in prior art, the drift blade a of place, b, c, d place in tetra-consistent gaps, limit, and when press work, a, b, c tri-blade places, limit are stressed, d limit does not stress, cause its unbalance stress of drift, make drift towards d limit skew or crooked, affected the service life of mould, and drift skew can affect the degree of accuracy of stamping-out, and then affect the quality of product.

Summary of the invention

The purpose of this utility model be propose a kind of simple in structure, with low cost, can improve die life simultaneously and ensure product quality for processing the drift of clutch shell fragment.

Described in the utility model a kind of for processing the drift of clutch shell fragment, comprise the drift body that is tile, upper surface, lower surface, front side wall and the rear wall of described drift body are plane, the left side wall of described drift body is the inner arc surface caving in to the right, and the right side wall of described drift body is the exterior arc surface protruding to the right; The right edge of the lower surface of described drift body is provided with the jacking block that is tile, and the right side wall of described jacking block and described exterior arc surface are coplanar, and the thickness of described jacking block on left and right directions is less than the thickness of described drift body on left and right directions; On the lower surface of the left side wall of described jacking block and described drift body, left side wall, front side wall, rear wall, be equipped with alloy coat, the hardness of described alloy coat is greater than the hardness of described drift body, and the color of described alloy coat is different from the color of described drift body and described jacking block.

Further, described jacking block and the described drift body structure that is formed in one.

Further, described alloy coat is TiN coating.

Owing to having adopted said structure, drift described in the utility model in use, is put blade clearance according to mould itself, and on drift body lower surface, a side of outer arc surface is the cutter that keeps to the side, be not subject to blanking pressure, when drift declines, jacking block first inserts in die and holds out against, and then other three limits just start stamping-out, can effectively prevent that like this drift is to exterior arc surface skew or crooked, and then guarantee product quality, in the life-span of simultaneously improving mould, prevent from directly impacting below punch because drift skew causes drift. The utility model is also provided with alloy coat on drift on this basis, alloy coat portion has not only strengthened the hardness of punch head surface, extend the service life of drift, be different from the color of drift body and jacking block due to the color of alloy coat simultaneously, so in the time that alloy coat is worn through, staff can observe easily and judge, to change in time drift, ensures the quality of product.

Detailed description of the invention

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

As shown in Figures 1 to 4 a kind of for processing the drift of clutch shell fragment, comprise the drift body 1 that is tile, upper surface, lower surface, front side wall and the rear wall of drift body 1 are plane, the left side wall of drift body 1 is the inner arc surface 2 caving in to the right, and the right side wall of drift body 1 is the exterior arc surface 3 protruding to the right; The right edge of the lower surface of drift body 1 is provided with the jacking block 4 that is tile, and the right side wall of jacking block 4 and exterior arc surface 3 are coplanar, and the thickness of jacking block 4 on left and right directions is less than the thickness of drift body 1 on left and right directions; On the lower surface of the left side wall of jacking block 4 and drift body 1, left side wall, front side wall, rear wall, be equipped with alloy coat 5, the hardness of alloy coat 5 is greater than the hardness of drift body 1, and the color of alloy coat 5 is different from the color of drift body 1 and jacking block 4.

Further, jacking block 4 and drift body 1 structure that is formed in one.

Further, alloy coat 5 is TiN coating, and the Vickers hardness of TiN coating is in 2300HV left and right, and maximum operation (service) temperature, at 500 DEG C, is a kind of high performance-price ratio coating, and TiN coating is golden yellow, the convenient abrasion condition of observing and judging coating.
