It adopts hydraulic drive, with reliable safety performance, easy operation, no need of anchor screws for installation, and diesel engine can be used as power in places without power supply. Shearing machine is suitable for metal recycling processing plants, scrap car dismantling yards, smelting and casting industries. It can perform cold shearing and flanging of various shapes of steel and various metal materials, as well as press forming of powder products, plastics, fiberglass, insulating materials and rubber. Shearing machine is divided into different types: metal shearing machine, combined punching and shearing machine, hydraulic shearing machine and bar shearing machine. The most commonly used metal shearing machines are crocodile shearing machine and gantry shearing machine.
[0003] Gantry shears are a kind of mechanical equipment used for metal processing, usually used for cutting, trimming and processing large metal plates. Its working principle is similar to a pair of large scissors. It clamps the metal plate between two parallel moving scissors and then applies force to cut or trim. However, the shearing knives of the current gantry shears are mostly directly fixed on the tool holder by screws. After long-term use, the screws are prone to rust. It is not convenient to disassemble when replacing the scissors, resulting in inconvenience in replacement. For this reason, we propose a cold shear tool holder locking device that is easy to disassemble to solve the above problems. Utility Model Content
