Problems solved by technology
During the use of the equipment, there are often cracks in the welds between the support ring, connecting plate and cylinder, which directly affect the normal use of the mixing station. This phenomenon has become a common problem in this industry.
At present, most manufacturers do not use tooling when assembling welding support rings, connecting plates, and cylinders, and directly weld without taking any technological measures for the weld bead. The deformation after welding is large and the internal stress is too concentrated, which causes the equipment to work. When the radial runout exceeds the standard; after the weld bead is stressed, the stress releases to cause weld cracking

Embodiment Construction
[0020] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.
[0021] Such as figure 1 , figure 2 As shown, the technical solution of the present invention is: a method for manufacturing asphalt mixing equipment, the steps of which are as follows: during the assembly and welding process of an asphalt mixing equipment, the cylinder body 3 is first placed on the supporting wheel when assembling On the support tooling 4, draw the position lines of the support ring 1 and the connecting plate 2 on the surface of the cylinder body 3 according to the size of the drawing. Then, install the expansion tooling 6 in the cylinder at the position corresponding to the support ring 1 inside the cylinder body 3, and adjust the ...

The invention provides a method for nufacturing asphalt mixing equipment, which is characterized in that a positioned barrel, a positioned backing ring, and the joint of a connecting plate are preheated by utilizing an electric heating device before being welded, and the welded asphalt mixing equipment is subjected to heat insulation treatment. The method has the advantages and beneficial effects that due to adoption of the technological scheme, the accuracy of equipment groups is improved, the welding deformation is controlled, the weld joint quality is improved, technological requirements can be completely met, and the technical problems that the radial runout momentum exceeds the standard, and the weld joint is cracked can be thoroughly solved.
Description
technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a manufacturing method, in particular to a method of manufacturing asphalt mixing equipment. Background technique [0002] The present invention relates to an asphalt mixing equipment, the main structure of which is composed of a support ring, a connecting plate and a cylinder. During the use of the equipment, cracking of the welds between the support ring, connecting plate and cylinder often occurs, which directly affects the normal use of the mixing station. This phenomenon has become a common problem in this industry. At present, most manufacturers do not use tooling when assembling welding support rings, connecting plates, and cylinders, and directly weld without taking any technological measures for the weld bead. The deformation after welding is large and the internal stress is too concentrated, which causes the equipment to work. When the radial runout exce...
