Problems solved by technology

Due to the large number of blades and the heavy weight of the blades in this operation mode, the labor intensity of the operator is high; when welding, the ventilation effect inside the tank is poor, and more harmful gases and dust are likely to be generated during the welding process, and the working environment is harsh. The physical health of the operator is damaged, and other reasons have become the bottleneck restricting the improvement of the mixer truck production capacity

Abstract

The invention relates to an assembly and welding tool for the tank body of a concrete mixer truck and mixing blades and a welding process using the welding tool, by attaching the shaped large segmented mixing blades to the blades on an inner cone male mold one by one The mother board is butt welded and finally becomes a complete spiral blade in a segmented tank. Then push the inner cone male mold into the segmented tank body through the lifting device, make the spiral blade and the tank body fit together, and perform rapid welding to fill the gap. . Finally, by rotating the tank body where the segmented tank is placed, the base plate is rotated, and the lifting device shrinks, so that the blade motherboard on the inner cone male mold is separated from the large piece of segmented spiral blade, and the inner cone male mold is withdrawn from the segmented tank body. . The welding tool and the welding process of the present invention avoid welding inside the tank body, and because the operating space is small, harmful gas and dust will affect the health of the operating staff.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an assembly welding tool for a tank body of a concrete mixer truck and a mixing blade and a welding process using the welding tool. Background technique [0002] The reason why the concrete mixer truck can mix and transport concrete and prevent concrete from solidification and segregation during transportation is that the spiral blade inside the core technology tank plays a vital role. The spiral blades are arranged inside the tank of the mixer truck in a special helical manner. In the previous production process, the workers placed the tank body of the mixer truck in sections in specific jigs, and then manually placed the tank inside the tank. After special stamping and forming, the stirring blades divided into small sections are lapped and welded inside the tank body step by step along the positions marked in advance on the inner surface of the tank in a certain order. Due to...
