Open-loop expanding machine suitable for flat conducting bar

Abstract

The invention discloses an open-loop expanding machine suitable for a flat guide bar, which comprises a first clamping device, a second clamping device and a radian clamping device, the first clamping device, the second clamping device and the radian clamping device are used for placing a workpiece, and the radian clamping device is arranged between the first clamping device and the second clamping device. The device comprises a first clamping device, a second clamping device, a radian clamping device, a central shaft, a left-right rotating power mechanism, a radian plate stabilizing motor, a reverse pulling mechanism and a control center, and the first clamping device, the second clamping device and the radian clamping device are all arranged at the axis position of the central shaft; the second clamping device is driven by the left-right rotating power mechanism to concentrically rotate around the center shaft so as to move towards the inner side, and the second clamping device limits the moving speed of moving towards the inner side under the reverse pulling force of the reverse pulling-in mechanism. The device solves the problem of consistent radian of the end part of the guide bar, is high in automation degree, is economical, can replace different dies, and greatly accelerates the processing period.

Description

technical field [0001] The invention relates to the field of new energy generator guide strip expansion equipment, in particular to an open-loop expansion machine suitable for flat guide strips. Background technique [0002] In the current new energy wind power industry, the motors for large-scale wind power generation generally use direct drive plus double-fed. Because double-fed can save a lot of raw materials, so now new energy wants to develop in double-fed, which can save raw materials. [0003] The guide bars used in the past were all round with a small diameter. They were all knocked out by molds and bent manually, resulting in large differences in the arc at the ends of the guide bars, low utilization of round wires, high groove fill rate, and poor heat dissipation. There are not many guide strips placed in wind power generation. The previous expansion machine is used to bend closed guide strips, and each coil of different brands and models (size and required arc sha...

Problems solved by technology

[0003] The guide bars used in the past were all round with a small diameter. They were all knocked out by molds and bent manually, resulting in large differences in the arc at the ends of the guide bars, low utilization of round wires, high groove fill rate, and poor heat dissipation. There are not many guide strips placed in wind power generation. The previous expansion machine is used to bend closed guide strips, and each coil of different brands and models (size and required arc shape) needs to be opened. Set of moulds, the process is cumbersome and takes up a lot of space;

[0004] Moreover, the technical disadvantage of the closed guide strip bending of the previous expansion machine is that the expansion arc of the guide strip needs to be composed of a supporting model arc die core and a bending fixing clip. During the bending process, the guide strip, arc die Between the core and the fixed clip, sometimes multiple adjustments and test lines are required, and it is difficult to remove and replace the mold. The whole process is mainly formed by manual beating and shaping, resulting in a large difference in the arc at the end of the guide bar. After embedding the inner and outer ring grooves low fit, poor stability

At the same time, the bending accuracy of the guide bar is prone to batch errors, and there is a lack of automatic bending devices and controls
