Roll-pressing narrow lap welding machine, welding process and moveable lining plates of roll-pressing narrow lap welding machine

Abstract

The invention provides a roll-pressing narrow lap welding machine and moveable lining plates thereof. The welding machine comprises a machine body, an inlet side lining plate assembly and an outlet side lining plate assembly, wherein the inlet side lining plate assembly consists of a first fixed lining plate, a first moveable lining plate and a first connecting piece; the outlet side lining plate assembly consists of a second fixed lining plate, a second moveable lining plate and a second connecting piece; the first moveable lining plate and the second moveable lining plate are provided with opposite first and second connecting side parts and opposite first and second non-connecting side parts; concavo-convex notches are formed in the first non-connecting side part and the second non-connecting side part; the first connecting side part and the second connecting side part are moveably connected with one side part of the first fixed lining plate and one side part of the second fixed lining plate through the first connecting piece and the second connecting piece; and the other side part of the first fixed lining plate and the other side part of the second fixed lining plate are fixedly connected with the inlet side and the outlet side of the machine body. The roll-pressing narrow lap welding machine and the moveable lining plates thereof have the advantages that the fact that the roll-pressing narrow lap welding machine equipment meets the processing and production requirements of hot-dipped aluminum zinc plates can be effectively guaranteed; spare part cost, processing cycle and processing difficulty are reduced; and the outage failure times are reduced and the waste defective rate is reduced.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanized plate processing equipment, in particular to a rolling narrow lap welder used as an inlet welder of a galvanized unit, a welding process and a movable liner. Background technique [0002] Usually, the galvanizing unit is one of the important equipment that constitutes the hot-dip galvanized sheet processing equipment. The rolling narrow lap welder is usually used as the entry welder of the galvanizing unit. [0003] In the prior art, the structure of the movable liner of the rolling narrow lap welder is unreasonable. Specifically, before the rolling narrow lap welder performs the welding task, it must first use the shear blade to cut off the head and tail of the reserved strip before welding. The cut off lead and tail will slide to the inlet and outlet chute of the rolling narrow lap welding machine through the movable liner of the rolling narrow lap welding machine, and then slide in...

AI Technical Summary

Problems solved by technology

However, due to the unreasonable structure, the movable liner of the rolling narrow lap welding machine in the prior art is often damaged or the swing is inflexible, resulting in the head and tail of the cut strip being stuck in the rolling narrow lap welding machine. In the frame, it hinders the normal welding of the rolling narrow lap welder

[0004] Due to the unreasonable structure of the existing movable liner of the rolling narrow lap welding machine, it is often damaged by cutting the leading and tail short plates during production and operation, causing the welding machine to fail to complete the welding process smoothly due to movement jams , which in turn leads to the deceleration or even shutdown of the galvanized unit

This seriously affects the normal continuous production of the galvanizing unit and causes a lot of waste and defective products
