A steel strip bending device

Abstract

The invention discloses a steel strip bending device. The steel strip bending device comprises a bending fixed base fixedly connected with a frame, a bending rotating base connected to the frame through a rotating structure, and a second driving mechanism for driving the bending rotating base to move; the bending rotating base consists of an upper connecting block, a middle bending block and a lower connecting block connected together; an upper rotating shaft and a lower rotating shaft are respectively arranged at the upper end and the lower end of the bending fixed base; the upper rotating shaft extends into the upper connecting block to form rotary connection; the lower rotating shaft extends into the lower connecting block to form rotary connection; a fixed bending surface is arranged on the bending fixed base; a rotating bending surface is arranged on the bending rotating base; the fixed bending surface and the rotating bending surface are arranged in a manner of face to face; and a second steel strip conveying channel is formed between the fixed bending surface and the rotating bending surface. The steel strip bending device can bend end parts of steel strips, is convenient for clamping by a manipulator through the bent parts, and is convenient to pull the steel strips.

Description

technical field [0001] The invention relates to material bending equipment, in particular to a steel strip bending device. Background technique [0002] In the production process of the transformer, it is necessary to use a thin steel strip to spirally wind the three-dimensional wound core of the transformer. In actual production, the steel strip needs to be pulled out from the steel coil to a certain length and cut off, and then wound with the cut steel strip. In the operation of pulling the steel belt, since the friction force of the flat steel belt is small, it is easy to slip, so the pulling operation is difficult. In actual production, in order to solve the above problems, the method of increasing the clamping force of the mechanical arm is usually used to increase the pulling force to realize the pulling task of the steel strip. However, this method has high requirements on the performance of the mechanical arm, which is not conducive to the promotion in actual produ...
