Description

Manufacturing device for wave-resisting plate of oil tank truck

Technical Field

The invention relates to an automatic production device, in particular to a device for manufacturing a wave-resisting plate of a tank truck.

Background

The wave blocking plate is a core part of the oil tank truck, is generally installed in the oil tank truck and is used for preventing liquid in the oil tank truck from generating waves when the oil tank truck runs and avoiding serious traffic accidents such as car turning, rear-end collision and the like caused by the waves. The production process of the wave-resisting plate of the oil tank truck at present comprises plate shearing, butt welding of flat plates, plasma cutting of inner circles, stamping forming, plasma cutting of outer circles, and welding of the wave-resisting plate and a coaming. The process flow of the welding process of the resistance plate and the enclosing plate comprises perimeter checking, splicing of the resistance plate and the enclosing plate, welding, cleaning of a welding seam, polishing, checking, acceptance checking and sequence transferring.

In the whole process, the welding process of the baffle and the coaming is difficult to realize, and on one hand, the size and the material of the baffle can be changed; on the other hand, the center of the baffle plate is required to be aligned with the center of the enclosing plate in the welding process of the baffle plate and the enclosing plate, and after the welding is completed, the perimeter error of the wave blocking plate is required to be in the range of-8 to +0 mm. At present, the process is basically finished by manual welding. Because the center of the baffle plate is required to be aligned with the center of the enclosing plate during welding, when the position of the baffle plate has a large error from the corresponding center line of the enclosing plate, welding personnel needs to knock and correct the baffle plate by visual inspection in the welding process, so that the distortion of the baffle plate and the enclosing plate is caused, the labor intensity of workers is increased, and noise is also generated. In the whole welding process of the baffle plate and the coaming, the manual welding can not ensure the continuity and uniformity of the welding, so that the machined baffle plate has random shapes and has great difference. And the manual welding efficiency is low, the welding quality depends on the welding process level of workers, and the influence dependence of production on human factors is larger.
