Assembly, system and method for changing cold shears of rod and wire cold shears

Abstract

The present application provides a component, system and method for replacing cold shears of a rod and wire cold shear, relating to the field of rod and wire cold shear production. The assembly includes two support wheels and a spreader, each support wheel is used to support the cold scissors and is in rolling contact with the cold scissors, the spreader includes a body, a locking piece and a lifting piece, the body includes two splints, and Two opposite and parallel grippers connected by a splint, each gripper has a limit groove for clamping the limit part, the lifting parts are respectively connected with the horizontal plates of the two grippers, and the lifting parts are equipped with a rope for installing There are hoisting holes, and the locking piece is threadedly connected with the horizontal plate, which is used to selectively lock the cold shears installed in the limiting groove and the body. Under the premise that only one spreader is installed for each cold shear, this component can not only meet the high level requirements during hoisting, reduce the difficulty of replacement, simplify the hoisting process and improve work efficiency, but also reduce the safety risk of hanging objects falling.

Description

technical field [0001] The present application relates to the field of bar and wire cold shear production, and in particular, to an assembly, system and method for replacing cold shear tools in a bar and wire cold shear machine. Background technique [0002] Bar and wire cold shearing is a key process to improve the yield of products and ensure the cutting quality of product sections, and the replacement of tools is an item that must be completed for each maintenance. Lift and replace with a crane. [0003] The above hoisting method makes each hoisting very cumbersome. And the actual tool holder is long, which requires high level of hoisting, the level of the hoisting position of the wire rope is not easy to grasp, and the replacement is very difficult, and the position of the wire rope needs to be adjusted repeatedly for each hoisting, resulting in prolonged maintenance time, and during the hoisting process. It is easy to cause the risk of slipping and squeezing the opera...

[0003] The above-mentioned hoisting method makes each hoisting very cumbersome

In addition, the actual tool holder is relatively long, which requires high hoisting level, and the hoisting position of the wire rope is not easy to grasp, so it is very difficult to replace, and the position of the wire rope needs to be adjusted repeatedly for each hoisting, resulting in prolonged maintenance time, and during the hoisting process It is prone to the risk of slipping and extruding workers, and there are potential safety hazards, and because the blades of the cold scissors are very sharp, the above-mentioned hoisting method needs to wrap the angle when hoisting, resulting in great bending damage to the steel wire rope, and at the same time, the sharp blade does not wrap the angle and it is easy to cut the wire rope. Safety risk of falling hanging objects
