Description

Technical Field

[0001] The present application relates to the field of welding technology, and in particular to a large-size high-frequency straight seam welded pipe equipment. Background Art

[0002] The welding principle of high-frequency straight seam welded pipes is mainly to use the skin effect and proximity effect of high-frequency current to achieve welding. When high-frequency current passes through the weldment, the energy is mainly concentrated in the surface layer of the weldment. This characteristic can be used to quickly heat the surface metal of the weldment, thereby achieving welding. Specifically, the high-frequency current produces local heating in the weldment, heating the edge of the tube blank to a molten state, and then pressure welding is performed under the action of the extrusion roller, eventually forming a strong weld. The application fields of high-frequency straight seam welded pipes include civil construction, petrochemicals, light industry and other departments. High-frequency welded steel pipes have the advantages of no need for weld fillers, no welding spatter, narrow welding heat-affected zone, beautiful welding shape, and good welding mechanical properties. Therefore, they are widely used in these fields;

[0003] When high-frequency straight seam welding is performed on large-sized pipes, it is not convenient to adjust the position of the pipes. The welding position is adjusted by simply using a rolling roller to drive the placed pipes to rotate. However, the position in the welding direction is not convenient. At the same time, the pipes are fixed by upper extrusion and positioned on the upper end of the roller. Due to the instability of the roller, the placement of the pipes is unstable. Therefore, we have proposed a large-sized high-frequency straight seam pipe welding equipment. Summary of the Invention

When adjusting, the driving motor 13 is started to drive the roller body 81 to rotate, so that the welding pipe placed on the upper end can be rotated to adjust the welding position of the welding pipe. When the welding position of the pipe is adjusted, the pressure plate 11 does not squeeze the welded pipe.

[0047] Specifically, the slide rail 24 is the track along which the slide rod 21 moves.

[0048] like Figure 2 As shown: the inner side of the sliding rod 21 is fixedly connected to the motor 19, the transmission rod of the motor 19 is fixedly sleeved with a gear 20, the lower end of the gear 20 is meshed with a rack 25, and the rack 25 is fixedly connected to the upper end of the support plate 3.

[0056] Principle of use: When the equipment is in use, the spring 16 is always in an extruded state, and the top of the supporting wheel 8 at the upper end of the supporting connecting rod 7 is higher than the upper end of the elastic rubber pad 12. Then, the pipe to be welded is placed on the upper end of the two supporting wheels 8 on the left or right side, and then the welded pipe is pushed to the left or right to move, so as to move the welded pipe to a suitable position. Due to the setting of the ball 83, the displacement of the welded pipe is more convenient. Then, the first electric telescopic rod 10 is started to drive the pressing plate 11, so that the pressing plate 11 squeezes the welded pipe downward, so that the welded pipe squeezes the supporting wheel 8 and the supporting connecting rod 7 downward, so that the lower part of the welded pipe is supported on the upper end of the elastic rubber pad, so that the placement and positioning of the welded pipe is more stable.

[0057] After the welding pipe is placed stably, the second electric telescopic rod 23 is started, and the second electric telescopic rod 23 drives the support plate 3 to move up and down, thereby adjusting the position of the support plate 3 and the position of the welding head 22;

[0058] After adjusting the height of the welding head 22, the first adjusting screw 54 and the second adjusting screw 56 are manually rotated to adjust the inclination angle of the connecting column 52, thereby adjusting the inclination angle of the welding head 22, so that the welding head 22 is adjusted to a suitable welding angle.
