Abstract

The invention relates to a bending die. The bending die comprises a male die body and a female die body. Supporting shafts which are used for supporting and bending a copper bar and matched with the male die body are arranged on the female die body. A first guide face for preventing the side wall of the copper bar from deforming and a second guide face corresponding to the first guide face are arranged on the female die body. An ejecting mechanism for ejecting the copper bar from the portion between the first guide face and the second guide face is arranged between the first guide face and thesecond guide face. The ejecting mechanism comprises swinging arms which are arranged on the supporting shafts in a sleeving manner and can rotate around the supporting shafts. According to the die, the groove matched with the copper bar for positioning is formed in the female die body. When the copper bar is bent, the first guide face and the second guide face can support the side wall of the copper bar, longitudinal bending and deformation of the copper bar are reduced effectively, and the copper bar is ejected upwardly through the ejecting mechanism after the copper bar is bent, so that thecopper bar can be formed at a time, the production efficiency is improved, the quality of products is guaranteed, and the safety is improved as well.

Description

technical field

[0001] The invention relates to a bending die. Background technique

[0002] Copper bars are very important in electrical equipment. During the installation of electrical equipment, copper bars often encounter connection problems. Because copper bars not only conduct electricity, but also play a role in installation, the processing of copper bars is particularly important, especially copper bars. row of bending work.

[0003] At present, copper bars are mostly bent by bending machines. The traditional vertical bending processing method is to manually bend copper bars on a bending machine with a hand-held copper bar. The existing copper bar bending mold has a simple structure, which is prone to bending deformation, or the copper bar is difficult to take out from the mold after bending the copper bar, which not only prolongs the production cycle, reduces production efficiency, but also improves product quality. not tall.
