Tunnel type welding system and operation method thereof

Abstract

The invention discloses a tunnel type welding system and an operation method thereof. The tunnel type welding system comprises a movable welding gun device and at least two tunnel type weldment loadersets; and the tunnel type weldment loader sets comprise welding pressing mechanisms, welding supporting assemblies and positioning mechanisms, wherein the positioning mechanisms comprise positioningdevices, position adjusting devices and position pressing devices. The operation method of the tunnel type welding system comprises the steps that each tunnel type weldment loader set can be changed over to correspond to loaded workpieces and carries out position and fixation, then the movable welding gun device carries out welding correspondingly, and then the workpieces are moved out of the tunnel type weldment loader sets. The tunnel type welding system and the operation method thereof can efficiently carry out precise welding of workpieces in batches, can be changed over immediately completed according to the size of a workpiece, and the changeover can be automatically completed without manual operation, so that the production efficiency is greatly improved, the time consumption and manpower are reduced, and flexibly configuration can be realized and the occupied area is reduced.

Description

technical field [0001] The invention relates to welding equipment, in particular to a tunnel welding system and its operating method. Background technique [0002] The current hollow cylinder structural parts such as water storage water heater liner and gas storage tank are all rolled into a cylinder shape by metal sheet, and then welded by welding equipment. The rounded workpiece is placed on the simple and fixed welding equipment for alignment, fastening, welding and removal, etc., with low efficiency and precision. [0003] Some existing automatic welding equipment can partially or completely carry out the corresponding welding process, and there are corresponding mechanical mechanisms for auxiliary or main operations in the process of feeding, positioning, fastening, welding and unloading, thereby reducing the unnecessary Automatic processing equipment needs the inherent inefficiency, high cost, and low precision of manual operation. [0004] At present, these existing...

Problems solved by technology

[0003] Some existing automatic welding equipment can partially or completely carry out the corresponding welding process, and there are corresponding mechanical mechanisms for auxiliary or main operations in the process of feeding, positioning, fastening, welding and unloading, thereby reducing the unnecessary Automatic processing equipment needs the inherent inefficiency, high cost and low precision of manual operation.

[0004] At present, these existing automatic welding equipment need to be set according to the size of the cylinder to be welded before operation or before loading the workpiece for feeding. Therefore, it is necessary to adjust or change the workpiece positioning fixture of the welding equipment, or even select Or replace the corresponding applicable positioning mold, and then correct various parameters to match the workpiece. Therefore, when the size of the workpiece to be processed changes, it will take corresponding time and labor costs, and it is impossible to quickly change the size of the workpiece. ; Moreover, these automatic welding equipment are integral single-channel welding structures, and can only perform loading, positioning, fixing and welding operations on a workpiece in sequence during the welding process at the same time, wherein during the loading and unloading process, Especially when it is necessary to adjust and set the corresponding workpiece size, the positioning or fixing mechanism, welding torch mechanism and other mechanisms are all in an idle state, so the overall operation efficiency of welding is not high; in continuous mass production, only one Welding equipment will obviously restrict production efficiency, so it can only be used to process workpieces of different sizes at the same time, or multiple equipments can be used on one production line at the same time for welding process to improve production line efficiency , its flexibility is not high, and multiple equipment occupies a large area, the processing efficiency and flexibility of these welding equipment are quite limited
