Detailed description of the invention
The embodiment of the present application, by providing the manufacture method of circular orbit in a kind of rotary drum, solves manufacture method in prior art and requires very high to the working ability of equipment, and the technical problem of high expensive.
Technical scheme in the embodiment of the present application is for solving the problems of the technologies described above, and general thought is as follows:
A manufacture method for circular orbit in rotary drum, described manufacture method comprises: obtain two strip-shaped steel plates; Veneer reeling machine is adopted to be rolled by described two strip-shaped steel plates bent shaping, annulus and outer toroid in obtaining; Adopt hot charging mode to be assemblied in described outer toroid by described interior annulus, and described interior annulus is fixed in described outer toroid, obtain circular orbit in described rotary drum; Circular orbit in described rotary drum is eliminated stress process.
In above-mentioned rotary drum, the manufacture method of circular orbit is by being divided into two-layer making by circular orbit in rotary drum, roll bent shaping, annulus and outer toroid in being formed, circular orbit in described rotary drum is formed by processing after heat assembling, this manufacture method, without using large-scale former, reduces manufacturing cost, has ensured the result of use of product simultaneously, solving manufacture method in prior art requires very high to the working ability of equipment, and the technical problem of high expensive.
In order to better understand technique scheme, below in conjunction with Figure of description and concrete embodiment, technique scheme is described in detail.
Require very high in order to solve manufacture method in prior art to the working ability of equipment, and the technical problem of high expensive, the application provides the manufacture method of circular orbit in a kind of rotary drum.As shown in Figure 1, in described rotary drum, the manufacture method of circular orbit comprises the following steps:
Step 110, obtains two strip-shaped steel plates.In the present embodiment, can utilize the steel plate of 75 millimeters respectively blanking cut into described two strip-shaped steel plates, its length is long according to the expansion of annulus, and considers that the steel plate linear expansion coefficient of different-thickness is determined, and cuts bevel for welding, and width stays allowance.
Described two strip-shaped steel plates are rolled bent shaping, annulus 2 and outer toroid 1 in obtaining, as shown in Figures 2 and 3 by step 120.Particularly, rectangularly roll bent shaping respectively with veneer reeling machine by two, cavetto, is welded into two annulus, and annulus 2 and outer toroid 1 namely, seam inspection is qualified.
