A large-scale steel bending equipment and bending process
The invention relates to a large-scale steel bending equipment and a bending process, comprising a bottom frame, a guiding mechanism, a bending mechanism and a shaping mechanism. The present invention can solve the following problems in the steel processing process: a. During the bending process of most steel materials, the steel materials are moved and the processing equipment is fixed. For large steel products, the existing equipment is used for processing The required site is large, and the realization process is relatively difficult. b. Most steel materials adopt a one-time forming method during the bending process. The stress generated during the bending process is relatively large, and it is easy to break just now. Insufficient treatment leads to uneven distribution of materials near the bending point, which affects subsequent use.
