First, the vertical clamp body adopts low alloy and high strength structural steel Q345B and adopts hollow structure, which is light and meets the strength requirements.
Secondly, on the premise of ensuring the ease of handling, the relationship between the coupling arm and the clamp tongue force arm is reasonably distributed, and the suitable tooth shape is designed at the contact part between the clamp tongue and the supporting table. Meanwhile, the contact surface between the clamp tongue and the supporting table and the steel plate is enlarged as far as possible, so as to increase the friction force and not damage the steel plate.
At last, the service life of the vertical pliers is greatly improved by proper heat treatment of the jaw and supporting table teeth.
