Assembly, system and method for replacing cold shearing tool of rod and wire cold shearing machine

Abstract

The invention provides an assembly, system and method for replacing a cold shearing tool of a rod and wire cold shearing machine, and relates to the field of rod and wire cold shearing production. The assembly comprises two bearing wheels and a lifting appliance, each bearing wheel is used for bearing the cold shearing tool and is in rolling contact with the cold shearing tool, the lifting appliance comprises a body, a locking piece and a lifting piece, the body comprises two clamping plates and two opposite and parallel claws connected through the clamping plate, each claw is provided with a limiting groove for clamping a limiting part, the lifting piece is connected with transverse plates of the two claws, the lifting piece is provided with a lifting hole used for installing a lifting rope, and the locking piece is in threaded connection with the transverse plates and used for selectively locking the cold shearing tool installed in the limiting grooves and the body. According to the assembly, on the premise that only one lifting appliance is installed on each cold shearing tool, the high levelness requirement during lifting can be met, the replacement difficulty is reduced, the lifting process is simplified, the working efficiency is improved, and the safety risk that a lifted object falls can be reduced.

Description

technical field [0001] The present application relates to the field of rod and wire cold shear production, in particular, to a component, system and method for replacing cold shears of a rod and wire cold shear. Background technique [0002] Cold shearing of rods and wires is a key process to improve the yield of products and ensure the quality of product cross-section shearing. Tool replacement is an item that must be completed for each maintenance. In the existing technology, steel wire ropes are used to lock the knife box and hang the chain hoist. Use a crane to lift and replace. [0003] Above-mentioned hoisting method causes each hoisting to be very loaded down with trivial details. 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 ...

Problems solved by technology

[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
