Description

Technical Field

[0001] The present application relates to the technical field of steel bar welding, and in particular to a steel bar electromagnetic hot-melt upsetting and lengthening device. Background Art

[0002] Rebar extension usually refers to the situation during the construction process where the length of the rebar is not enough to meet the requirements of the structural components, and two or more rebars need to be connected to meet the length requirements.

[0003] There are three main methods of extending steel bars: binding overlap, mechanical connection and welding.

[0004] The main reinforcement used in existing construction reinforcement projects is mostly 9-12m fixed-length bars, and the diameter of the steel bar material is relatively large. A single steel bar needs to be cut to form a length that meets the actual construction needs. A large amount of surplus material will be generated in the cutting process, which is difficult to use. After the surplus material is reused, it will still produce tailings, which is still a loss and waste, increasing the cost of the reinforcement project.

[0005] In addition, the conventional method of steel bar welding is to heat the ends of the steel bars to melt them, and then cool and solidify them to form a connection. The welded connection has high strength, but has high requirements on the construction process and slow work efficiency. The welding slag generated during welding requires additional cleaning, and the cleaning effect is poor, which affects the subsequent construction process. Summary of the invention

At the same time, when the steel bar 10 is subsequently cooled from 1400° to 500° to 600°, its cooling speed is accelerated, shortening the cooling time.

[0080] See also Figure 1 The electromagnetic hot-melt upsetting and lengthening device for reinforcing bars also includes a control area 13, which is arranged on the base 1 and located in front of the processing area 12.

[0081] In summary, when it is necessary to weld two steel bars 10, firstly, the two steel bars 10 are placed in the clamping scraper assembly 5, and the two steel bars 10 are clamped and fixed by the clamping scraper assembly 5, and at the same time, the clamping scraper assembly placed on the movable plate 3 is pushed toward the fixed plate 4 by the jacking device 2, so that the welding surfaces of the two steel bars 10 are in contact with each other, and at the same time, the electromagnetic hot-melt welding part 8 is turned on to heat and melt the welding part of the two steel bars 10. After reaching the specified temperature, the movable plate 3 is driven to move by the jacking device 2 again, so that the movable plate 3 is set on the movable plate 3. The steel bar 10 on the upper side moves toward the other steel bar 10, and the two steel bars 10 are squeezed against each other to improve the bonding force. When the top forging welding is completed, the clamping and scraping assembly 5 slightly loosens the steel bar 10, and first uses the clamping cylinder 64 to drive the clamping block 63 to clamp one end of the welded steel bar 10, and then uses the moving cylinder 65 to drive the entire moving plate to move, thereby pulling the steel bar 10 to move. In the process of the mobile clamping assembly 6 clamping and pulling the steel bar 10, when the welding slag on the surface of the steel bar 10 passes through the two clamping blocks 53, due to the two arc-shaped depressions 531, the welding slag on the surface of the steel bar 10 is pressed against the two clamping blocks 53. The welding slag on the outside of the steel bar 10 can be squeezed by the side wall of the arc-shaped depression 531, and finally scraped off by the clamping block, so that the welding slag on the steel bar 10 can be initially scraped off, and the scraped steel bar 10 can continue to move under the traction of the mobile clamping assembly 6, passing through the rotating pipe formed by the deflection arc plates 742 inside the two scraping pieces, because the deflection roller 744 with a rotation direction at a certain angle to the traveling direction of the steel bar 10 is set on the inner wall of the deflection arc plate 742, so that the steel bar 10 During the relative displacement with the deflection roller 744, the deflection roller 744 can move in a spiral manner along the outer surface of the steel bar 10, thereby driving the two deflection arc plates 742 to rotate around the steel bar 10, so that the welding slag remaining on the steel bar 10 after the initial scraping can be completely scraped off during the rotation and movement of the two deflection arc plates 742, and the secondary scraping assembly 7 is used to perform secondary scraping on the moving steel bar 10, thereby improving the scraping efficiency and thoroughness of the steel bar 10 to ensure the smooth progress of subsequent processes.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
