Description

Technical Field

[0001] This utility model mainly relates to the field of angle iron production technology, specifically to a punching and forming device for angle iron production. Background Technology

[0002] In the production of angle iron, punching is required in the product design. However, there is a discrepancy in the production cycle matching between the punching machine and the angle iron forming machine, which results in the steel strip being too long and dragging on the ground when it is conveyed from the punching machine to the angle iron forming machine.

[0003] The inventor proposes a punching and forming device for angle iron production, which sets up a lifting device between the punching machine and the angle iron forming machine to provide support and protection between the steel strip and the ground, so as to avoid the steel strip dragging on the ground or the steel strip bending too much between the punching machine and the angle iron forming machine, which is not conducive to subsequent forming processing.
