Bending and forming die for automobile hollow lifting hook

Abstract

The invention aims to provide a bending and forming die for an automobile hollow lifting hook. The bending and forming die comprises two pairs of forming dies. One pair of the forming dies comprises a left die and a right die, and the left die and the right die are arranged on the left side and the right side of a hollow pipe fitting respectively. The other pair of the forming dies comprises a front die and a back die, and the front die and the back die are arranged on the front side and the back side of the hollow pipe fitting respectively. The shape of the back end surface of the front die and the shape of the front end surface of the back die are identical with the bent shape of the needed lifting hook of left view. The left die and the right die are of plate structures identical with the bent shape of the needed lifting hook of left view. The shape of the right end surface of the left die and the shape of the left end surface of the right die are identical with the bent shape of the needed lifting hook of principal view. Grooves of the same shape are formed in the end surfaces, close to the hollow pipe fitting, of the left die, the right die, the front die and the back die in the vertical direction. Due to two pairs of the forming dies, the hollow lifting hook of any continuous curvature can be machined and formed at a time. The arc-shaped grooves are formed in the forming dies, and therefore bad deformation of the hollow pipe fitting in the forming process is eliminated, the bending accuracy is guaranteed, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a mold for rapid bending and forming of an automobile hollow hook. Background technique [0002] There are all kinds of hollow hooks on the car. Due to their special needs, one end of the hook needs to be in a continuous certain angle or curved arc. Since there is no special tooling mold for this continuous bending process at present, in order to meet the bending requirements, the operator can only bend and correct the shape multiple times, the process is complicated, and the work efficiency is low; and due to the particularity of the hollow hook , so that the hardness of the pipe fittings is not enough, the roundness of the pipe fittings is easily deformed during the processing process, and the bending accuracy is not high. The pipe fittings with serious deformation can only be scrapped, causing economic losses and affecting work efficiency. Therefore, it is neces...
