Twisting mold of fat steel and flat steel twisting method

Abstract

The invention discloses a twisting mold of flat steel and a flat steel twisting method. The twisting mold of the flat steel comprises a base, a supporting seat I, a supporting seat II and a rotating block, the supporting seat I and the supporting seat II are fixedly arranged on the upper surface of the base in a face-to-face mode, the rotating block is arranged between the supporting seat I and the supporting seat II, and the rotating block is rotatably and movably connected with the supporting seat I; the rotating block is provided with an inserting groove I, the supporting seat II is provided with an inserting groove II, the inserting groove I and the inserting groove II are arranged in a fact-to-face mode, and the shape and the size of the inserting groove I and the inserting groove II are matched with the size and shape of the portion to be clamped of the flat steel to be processed; a rotating and driving unit drives the rotating block to rotate relative to the supporting seat I; a distance which matches with the length of the flat steel is reserved between the rotating block and the supporting seat II. The twisting mold of the flat steel has a simple structure and guarantees the twisting accuracy through the structure of the twisting mold of the flat steel. According to the flat steel twisting method, a mechanical cold working mode is utilized, material damage caused by uneven heating is avoided, meanwhile, the labor intensity of workers is reduced and the processing efficiency is improved.

Description

technical field [0001] The invention relates to a flat steel torsion mold and a method for torsion flat steel. Background technique [0002] A commonly used connector on a transmission tower, such as figure 1 As shown, it is made by bending flat steel. Due to connection requirements, part B must be twisted 90 degrees relative to part A. o , so that the surface of part B is perpendicular to the surface of part A. [0003] The method for realizing the twisting of the above-mentioned angle steel usually adopts oxy-acetylene flame heating or heating in a heating furnace, and after reaching a certain temperature, twisting is manually performed by using simple tools. The disadvantages of this processing method are as follows: [0004] (1) The heated joints are manually twisted and formed, which has high working strength, low processing efficiency, large dust in the working environment, and serious harm to the workers' bodies; [0005] (2) Partial heating of the connecting part...
