Embodiment
[0025] Such as Figure 1 to Figure 3 As shown, the heating recovery method of the steel deformed area of the present invention includes a support table 1, a first connecting rod 3, a cross bar 4 and a second connecting rod 15, and the support table 1, the first connecting rod 3, the cross bar 4 and The second connecting rod 15 is connected end to end in turn to form a closed structure. A rotating element 2 is arranged between the supporting platform 1 and the first connecting rod 3. Both the supporting platform 1 and the first connecting rod 3 can surround the rotating element 2. The supporting platform 1 Both the first connecting rod 3 and the first connecting rod 3 can rotate around the rotating element 2. The support platform 1 is in the shape of an arc, and the inner side of the arc of the support platform 1 is provided with a gasket 13. The gasket 13 is preferably made of rubber material and has a certain Elastic, and can protect the steel placed in the support platform...

The invention discloses a steel deformation zone heating type recovery method comprising the following specific steps that firstly, a nut is loosened, a threaded rod is pulled, to-be-machined steel is placed onto a support table, and the deformation zone of the steel is located under a welding block; the a rotary handle on a first movable rod is adjusted, thus a heating block tightly presses the outer wall of the steel, a rotary handle on a second movable rod is rotated, thus the welding block makes contact with the inward-concave deformation zone of the steel, and the welding block and the concave zone of the steel are welded together through electric welding; and finally, a heating wire is electrified, hear produced by the heating wire is transmitted to the steel through a thermal conductive layer and heats the steel, when the steel reaches certain temperature, the rotary handle on the second movable rod is rotated till the welding block stretches the concave zone to be flush with the outer wall of the steel, and recovery of the deformation zone of the steel is completed.
Description
technical field [0001] The invention relates to a steel processing device, in particular to a heating recovery method in a steel deformation area. Background technique [0002] Steel is widely used and has a variety of varieties. According to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products. Steel is an essential material for national construction and the realization of the four modernizations. It is widely used and has a wide variety. According to the different cross-sectional shapes, steel products are generally divided into four categories: profiles, plates, pipes and metal products. Section steel, small section steel, steel cold-formed section steel, high-quality section steel, wire rod, medium and thick steel plate, thin steel plate, silicon steel sheet for electrical purposes, strip steel, seamless steel pipe steel, welded steel pipe, metal products, etc. In the process of steel productio...
