Description

Technical Field

[0001] The utility model relates to the field of copper rod processing equipment, in particular to a copper rod bending tool. Background Art

[0002] As a good conductive material, copper rods are widely used in the manufacture and maintenance of electrical equipment. For example, copper rods can be used for electrical grounding and wiring. Especially in the case of high current transmission, copper rods are a reliable conductive material. Therefore, copper rods are widely used in power systems, railway electrical equipment and other fields. During the processing and use of copper rods, they usually need to be bent into a set shape according to the use position. The bending process requires bending tooling. The current bending tooling can only bend one copper rod workpiece at a time, which has low production efficiency. At the same time, the bent copper rod cannot be placed stably and autonomously when one end is tilted, which makes the copper rod unable to be bent a second time, and has poor practicality.

Two sets of top molds and bottom molds are arranged in parallel, so that the bending process of two copper rods can be completed synchronously, thereby improving production efficiency. In addition, a baffle is added at the tail of the copper rod workpiece to support the raised part of the copper rod that is bent for the second time, so as to obtain a fixed tool that can bend copper rods with angles, thereby expanding the processing range.
