Background

At present, a large part of processes for manufacturing bent parts in the manufacturing industry need to use stretch bending equipment to complete processing, stretch bending processing is not separated from development and manufacturing of stretch bending dies, and the processes are basically divided into two types according to the current die development processes in the industry: bakelite solid stretch-bending die and iron solid stretch-bending die. The solid bakelite plate stretch bending die has more disadvantages in the development process, (1) loss of materials is caused by the fact that a plurality of bakelite plates are needed to be spliced and manufactured by dies with larger sections due to the limitation of the thickness of the bakelite plates on the market, 2. Repeated die repair is caused by uneven verticality of the arc surface of the die due to the fact that radian is basically polished manually in the die development and manufacturing process, 3. Loosening and surface abrasion of the die are easily caused by long-time repeated use of the die spliced by the bakelite plates, the solid stretch bending die is the same as the solid stretch bending die in the development process, (1) cost increase is caused by the large waste of raw materials, 2. The solid iron die is too heavy in weight and is very heavy in the use process, and the safety of workers can be reduced correspondingly), and aiming at the defects of the two dies, a novel iron hollow stretch bending die is invented after continuous simulation and actual examination.
