[0002] After searching Chinese patents, the publication number is: CN103071725B, a flattening device for angle steel, which has a simple structure and can realize the mechanized operation of angle steel flattening operation. The flattening device includes a clamping mechanism, an induction heater and a flattening mechanism for heating and flattening the angle steel respectively, the induction heater heats the outer side of one side limb of the angle steel, the flattening mechanism is arranged on the outer side of the side limb, and the clamping mechanism clamps and fixes the other side limb of the angle steel so that the flattening mechanism squeezes the outer side of the heated side limb inward. The entire operation process is completed through mechanization, and its automation degree is relatively high, which is conducive to improving production efficiency; the flattening device includes a clamping mechanism, a heater and a flattening mechanism that cooperate with each other, and its structure is simple and the operation is flexible and convenient; the temperature and extrusion force required for flattening can be precisely controlled to improve the accuracy of flattening.

[0003] The existing flattening device does not have a punching function. Generally, the flattening device can only flatten the angle steel. During the production process, the flattened angle steel needs to be punched. Generally, the flattened angle steel is transported to a punching machine for punching, which increases the workload and reduces the production efficiency. The flattening length cannot be adjusted. Generally, the mold length of the flattening device is fixed. If the flattening length needs to be changed, the mold needs to be replaced, or a mark needs to be made on the angle steel before flattening. This is very troublesome, increases the workload, reduces the production efficiency, and is inconvenient to use.
