When welding a pair of elbows at their contact points, automatic rotation is required to ensure welding stability. However, traditional welding is mostly done manually with a handheld welding torch, which cannot achieve perfect automatic welding. Therefore, a ferrous metal smelting elbow welding equipment is needed. Utility Model Content

Therefore, this invention proposes a welding equipment for elbows in ferrous metal smelting.

A turntable is rotatably connected to the surface of the fixing ring. An annular corrugated groove is formed on the surface of the turntable. A ball head is fixedly connected to the surface of the L-shaped plate. The ball head is installed inside the annular corrugated groove and in close contact with the inner wall of the annular corrugated groove. A positioning welding mechanism is installed on the surface of the raised seats.

[0011] Preferably, a spur gear is fixedly connected to the output end of the motor, the spur gear meshes with an external gear ring, and a clearance hole is provided on the surface of the support plate.

[0012] The beneficial effects of this utility model are as follows:

[0021] By setting a fixed ring 4, the rotation of the turntable 5 is kept stable; by setting a guide plate 8, the sliding of the L-shaped plate 10 is kept stable; by setting friction pads 11, the clamping is kept stable; by setting an annular wave groove 7, the distance between multiple friction pads 11 is adjusted; and by setting a positioning welding mechanism, elbows of different diameters are clamped and welded, maintaining the stability of the automatic welding circle.

[0022] In this utility model, reference is made to Figure 3 The positioning welding mechanism includes a fixed box 12 fixedly connected to the surface of the lifting seat 2. A spring telescopic rod 13 is fixedly connected to the inner wall of the fixed box 12. A trapezoidal block 14 is fixedly connected to one end of the spring telescopic rod 13. The surface of the trapezoidal block 14 is slidably connected to the inner wall of the fixed box 12.

[0023] By setting the spring telescopic rod 13, the trapezoidal locking block 14 is driven to reset. By setting the trapezoidal locking block 14 to cooperate with the inclined groove 15, the angle of the turntable 5 is positioned.

[0024] In this utility model, reference is made to Figure 3 The surface of the turntable 5 is provided with multiple inclined grooves 15, the surface of the trapezoidal block 14 is adapted to the inner wall of the inclined groove 15, and the surface of the turntable 5 is fixedly connected to an adjusting sleeve 6, and the surface of the adjusting sleeve 6 is fixedly connected to an anti-slip sleeve 23.

[0025] By setting the anti-slip sleeve 23, the friction of the rotating adjusting sleeve 6 is increased. By setting the adjusting sleeve 6, the turntable 5 is driven to rotate for angle adjustment.

[0026] In this utility model, reference is made to Figure 4A support plate 3 is fixedly connected to the upper surface of the base 1, a protective ring 21 is fixedly connected to the upper surface of the support plate 3, a slider 22 is slidably connected to the inner wall of the protective ring 21, and a welding head 20 is fixedly connected to the surface of the slider 22.

[0027] By setting a protective ring 21, the slider 22 is kept stable within the protective ring 21. By setting a welding head 20, the elbow pipe within the protective ring 21 is welded in a circular motion.

During this process, the trapezoidal locking block 14 repeatedly compresses the spring telescopic rod 13, making it shorter. When the turntable 5 does not rotate, the trapezoidal locking block 14 engages with the inclined groove 15 to maintain stability. The turntable 5 rotates through the annular wave groove 7, which drives multiple L-shaped plates 10 to move closer to each other through multiple ball heads 9. The elbow pipes are positioned and clamped by the friction pads 11. Then, the motor 16 is started, which drives the spur gear 17 to rotate. The spur gear 17 drives the rotating ring 19 to rotate through the external gear ring 18. The rotating ring 19 drives the slider 22 and the welding head 20 to move together. The welding head 20 slides within the protective ring 21 to maintain stability. The welding head 20 rotates once to automatically weld a pair of elbow pipes. With the above structure, elbow pipes of different diameters can be welded into circles.
