Channel steel plate manufacturing bending die and application method

Abstract

The invention provides a channel steel plate manufacturing bending die. The channel steel plate manufacturing bending die comprises an upper die and a lower die. The upper die is of a T-shaped structure, and comprises an upper die top plate, an extending section, a bending contact portion and a workpiece hole locating device. The extending section is arranged at the bottom of the upper die top plate, the bending contact portion is arranged at the bottom of the extending section, and the workpiece hole locating device is fixedly arranged at the bottom end of the bending contact portion. The lower die is of a U-shaped structure, and comprises a lower die bending base body, a lower die base plate, material removal compression springs, a material removal plate and a baffle. The lower die bending base body is arranged on the top of the lower die base plate, the material removal compression springs are arranged on the lower die base plate and located on the two sides of the lower die bendingbase body, the material removal plate is fixedly arranged on the tops of the material removal compression springs on the two sides, and the baffle is arranged on the side face of the lower die bending base body and connected with the lower die bending base body through bolts. The channel steel plate manufacturing bending die effectively accomplishes steel plate bending and effective material removal, eliminates the workpiece hammering taking mode, and is safe and efficient.

Description

technical field [0001] The invention relates to the field of steel plates for making foot nails for power transmission lines, in particular to a punching and bending die for making groove-shaped steel plates and a use method thereof. Background technique [0002] Due to the small size of the grooved foot nails, there is a certain strength and rebound coefficient when the steel plate is used for bending. It is difficult to take out the formed grooved workpieces from the bending mold. Usually, hammers are used to knock them out, which is inefficient and has potential safety hazards. To sum up, the existing molds cannot safely and efficiently produce channel-shaped steel plates that are actually required. It requires a lot of manpower, material resources and time investment to ensure quality, and the pass rate of workpieces is low. Therefore, a channel-shaped steel plate is needed to make punching and bending die Make channel steel plates. Contents of the invention [0003] ...
