Control Method for Head and Tail Shearing of Rods and Wires

Abstract

The invention discloses a bar and wire head and tail shearing control method. The control method comprises the following steps that firstly, bars and wires are selected, and are placed on shearing equipment, and distance L of every two adjacent bars and wires is measured; then the travelling circumference C of the equivalent radii of shear blades of flying shears in the shearing equipment, the length L<1> of head shearing and the length L<2> of tail shearing are measured; and finally, the positions of the shear edges of the flying shears are judged, and head and tail shearing is conducted on the bars and wires. According to the bar and wire head and tail shearing control method, the problem that in the prior art, when bars and wires are rolled at a high-speed, the head and tail shearing through flying shears is disordered is solved.

Description

technical field [0001] The invention belongs to the technical field of rod shearing, and relates to a control method for head and tail shearing of rods and wires. Background technique [0002] Flying shears are commonly used equipment in steel bar and wire production lines. At the same time, if an accident occurs during production, the flying shears can also achieve the function of breaking to ensure production safety. [0003] With the upgrading of technology, the rolling speed of rods and wires is getting faster and faster. However, the traditional flying shears limit the further improvement of the rolling speed of steel bars and wires. In the existing rolling line production, the 1# and 2# flying shears often have the situation that the head cutting command and the tail cutting command overlap when the rhythm is too fast, which will be accompanied by cutting the tail without cutting the head or not cutting the head The phenomenon of not cutting the tail, especially the ...
