Industrial washing machine washing internal cylinder with non-welded structure and manufacturing method thereof

Abstract

The invention discloses an industrial washing machine washing internal cylinder with a non-welded structure and a manufacturing method thereof. Assemblies of the washing internal cylinder comprise a machined cylindrical net sheet, wherein meshes are formed on the net sheet uniformly; a front end cover and a rear end cover of the internal cylinder are fixedly connected with both ends of the cylindrical net sheet; a plurality of lifting tendons are arranged on the inner wall of the net sheet at intervals; flangings overturning outwards are arranged on edges at front and rear ends of the net sheet; hemmings overturning outwards are arranged on edges of the front and the rear end covers; the lifting tendons are attached to the inner wall of the net sheet closely, and both ends of the lifting tendons are clamped between the front and the rear end covers closely; and the hemmings on the front and the rear end covers are mutually meshed with the flangings on the net sheet. In the washing internal cylinder, the net sheet, the lifting tendons and the front and the rear end covers are integrated by a stamping connection forming method; and the assemblies of the integral internal cylinder avoid welding and internal stress at joints, so that the internal cylinder has small deformation, good quality and long service life, and does not damage linen.

Description

technical field [0001] The invention relates to the technical field of industrial washing machines, in particular to an inner drum of an industrial washing machine, in particular to an inner drum of an industrial washing machine with a welding-free structure and a manufacturing method thereof. Background technique [0002] At present, the laundry inner tub of industrial washing machines on the market is mainly composed of several main components such as inner tub mesh, lifting ribs, front and rear end covers, and most of the components are fixedly connected by welding. Including the welding of the lifting rib and the inner wall of the mesh, the welding of the front and rear end covers and the two ends of the mesh, etc. However, practice has shown that the laundry inner tub of this traditional connection method has many defects during use: [0003] 1. The welding scars formed at the welding place between the components are very obvious, and its appearance is very unsightly; ...

AI Technical Summary

Problems solved by technology

[0003] 1. The welding scars formed at the welding place between the components are very obvious, and its appearance is very unsightly;

[0004] 2. There is a large internal stress at the welding place between components, which will deform after a period of use, thus reducing the service life of the whole machine;

[0005] 3. Due to the burrs that are difficult to polish on the welding surface of the inner and outer walls of the washing machine, the linen will be severely strained during the washing process;

[0006] 4. Ordinary electric welding equipment is used for welding, with low processing accuracy and serious influence of human factors, so that the overall quality of the equipment cannot be effectively guaranteed;

[0007] 5. Its quality is not easy to control in the production process, and the production process is relatively poor, and the production efficiency is low, so it is not easy to produce in large quantities
