Abstract

The invention discloses a special arc traceless bending die, and relates to the technical field of bending dies. The special arc traceless bending die comprises an upper bending die, a polyurethane round bar and a lower die mounting seat; a mounting notch is formed in the upper part of the left side of the upper bending die; a bolt through hole is formed in the upper bending die, and an anti-skid layer is arranged on the outer surface of the lower end of the upper bending die. By means of the polyurethane round bar and the upper bending die which are distributed in parallel, the position accuracy between the polyurethane round bar and the upper bending die can be guaranteed, by combination with the bottom of the upper bending die of a V-shaped structure, the polyurethane round bar is well limited and effectively prevented from moving left and right, and the stability of the special arc traceless bending die in the actual bending process is improved; and polyurethane round bars with different sizes can be replaced conveniently according to the actual bending radian through connecting bolts and the polyurethane round bar connected with the upper bending die, the optimal bending effect is achieved, the situation that a product has tool marks is effectively avoided, and the actual use range of the bending die is widened.

Description

technical field [0001] The invention relates to the technical field of bending dies, in particular to a special circular arc traceless bending die. Background technique [0002] As we all know, with the continuous improvement of people's living standards and industrialization, people have higher and higher requirements for the appearance of sheet metal structural parts. At present, many sheet metal parts use a plate with a coating (plating) layer to bend it through a conventional arc bending die, and a bending die is required in the product bending process. [0003] Most of the bending molds on the market use standard arc molds when making prototypes or small batches of arc products, and some non-standard arcs are bent by single-knife feed, which has obvious bending Scimitar marks seriously affect the beauty of the product. Contents of the invention [0004] The purpose of the present invention is to provide a special circular arc traceless bending die to solve the probl...
