Abstract

The invention discloses a horseshoe type high-strength link ring forging, bending and compression molding technology. The technology comprises the following steps that S1, material selection is conducted, specifically, a bar with the proper diameter is selected according to the design budget; s2, blanking treatment is conducted, specifically, the selected bars are cut; s3, heating treatment is conducted, specifically, the cut bar is heated to the required forging temperature; s4, pre-forging treatment is conducted, specifically, the bar is subjected to pre-forging preliminary forming on a matched press machine, and a long-strip forge piece is obtained; s5, trimming is conducted, specifically, redundant flashes are cut off from the long-strip forge piece subjected to pre-forging and preliminary forming; s6, bending and compression molding are conducted, specifically, the long-strip forge piece is subjected to rapid bending and shaping treatment, and a forge piece is obtained; s7, correction treatment is conducted, specifically, correction treatment is conducted on the press machine and the bent forge piece; and S8, natural cooling is conducted, specifically, natural cooling treatment is conducted on the bent and shaped forge piece. The horseshoe type high-strength chained ring prepared by the invention is relatively high in compression strength and relatively high in raw material utilization rate.

Description

technical field [0001] The invention relates to the technical field of link ring forging and processing, in particular to a horseshoe-type high-strength link ring forging, bending and die forming process. Background technique [0002] The horseshoe-type high-strength link ring forging, bending and pressing molding technology is a kind of mining equipment (material transmission machinery accessory production technology), and is an essential machine in the implementation of mining production activities. The role of the machine is to complete the transfer of ore materials to the designated location or provide convenience for the transportation of mineral materials. The main working principle of the transfer machine is that the motor drives the conveyor belt to rotate circularly, and the moving conveyor belt sends the mined ore materials to the designated location or In the carrying box of the transport vehicle. It is transported to places where it is needed to complete mining ...
