[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a turntable assembly for cutting large-diameter elbows, including a turntable assembly 1, a cutting mechanism 2 and a slag collection tank 3. The turntable assembly 1 is used for feeding and discharging materials, the cutting mechanism 2 is used for cutting, and the slag collection tank 3 is used for collecting the remaining materials dropped during cutting. The turntable assembly 1 includes a rotary drive base 11 and a rotating disk 12. A plurality of positioning assemblies 13 are arranged on the rotating disk 12. The positioning assembly 13 is composed of a plurality of positioning pins 131. The cutting mechanism 2 is located on one side of the turntable assembly 1, and the slag collection tank 3 is located below one side of the turntable assembly 1.

[0024] Among them, a plurality of positioning assemblies 13 for fixing the elbows to be cut are provided on the turntable assembly 1. The rotating disk 12 of the turntable assembly 1 rotates a certain angle each time, moves the elbow to be cut into the cutting position, and at the same time moves the cut elbow out. By continuously rotating to move the elbow, the feeding and discharging of the elbow are realized, and then the continuous cutting of the elbow is realized through the cutting mechanism 2, improving the cutting efficiency of the elbow, replacing manual cutting, and being suitable for the efficient cutting of a large batch of elbows.

[0025] Among them, the rotation direction and rotation angle of the turntable assembly 1 are controlled by the rotation direction and the number of rotation turns of the rotation motor inside the rotary drive base 11.

[0026] Among them, a placement position is formed between a plurality of positioning pins 131, and the elbow body 4 is placed in the placement position.

[0027] Among them, the fixed positions of the plurality of positioning pins 131 are adapted to the bending arc of the elbow body 4. As Figure 4 shown, when the elbow body 4 is placed in the placement position, the plurality of positioning pins 131 are in close contact with the outer surface of the elbow body 4, so as to realize the positioning and fixing of the elbow body 4.

[0028] Among them, the cutting mechanism 2 includes a vertical frame 21, a first cutting assembly 22 and a second cutting assembly 23. Both the first cutting assembly 22 and the second cutting assembly 23 are connected to the vertical frame 21 through a fixing seat 24.

[0029] Among them, the first cutting assembly 22 cuts along the cutting line on one side of the elbow body 4, and the second cutting assembly 23 cuts along the cutting line on the other side of the elbow body 4.

[0030] Among them, the first cutting component 22 and the second cutting component 23 are respectively located on both sides of the lower end of the vertical frame 21. The two groups of cutting components can cut along the cutting lines on both sides of the elbow body 4 respectively, cut the elbow body 4 into a specified size, and the remaining materials cut off fall into the slag collecting tank 3 and are centrally collected by the slag collecting tank 3.

[0031] Among them, the cutting position of the cutting mechanism 2 can be adjusted accordingly according to the cutting requirements, and the installation positions of multiple groups of positioning pin shafts 131 can also be adjusted accordingly according to the cutting requirements, so as to meet various usage requirements.

[0032] Among them, both the first cutting component 22 and the second cutting component 23 include an electric cylinder 221, and one end of the push rod of the electric cylinder 221 is connected to a driving seat 222. A flame cutting gun 223 is fixedly arranged on the driving seat 222. When the electric cylinder 221 works, it drives the flame cutting gun 223 at one end thereof to move linearly.

[0033] Among them, the flame cutting gun 223 is connected to a torch assembly. Both the first cutting component 22 and the second cutting component 23 are flame cutting components. The first cutting component 22 and the second cutting component 23 use the heat generated by the combustion of oxygen to cut the elbow body 4. The cutting method is simple and suitable for the cutting process of large-diameter elbows.

[0036] Among them, the output shaft of the rotating motor is fixedly connected to the connecting shaft of the driving plate 14 through a coupling. When the rotating motor works, it drives the connecting shaft, drives the driving plate 14 through the connecting shaft, and drives the rotating disk 12 through the driving plate 14. When the elbow body 4 is placed in the positioning assembly 13 on the upper part of the rotating disk 12, the elbow body 4 moves synchronously with the rotating disk 12.

[0037] Working principle: A placement position is formed between multiple groups of positioning pin shafts 131, and the fixed positions of multiple groups of positioning pin shafts 131 are adapted to the bending radian of the elbow body 4, such as Figure 4As shown, the elbow body 4 is placed in the placement position and positioned and fixed by multiple groups of positioning pin shafts 131. The rotation motor built in the rotation drive base 11 works to drive the rotating disk 12. The rotating disk 12 of the turntable assembly 1 rotates a certain angle each time, and the elbow to be cut is moved into the cutting position. The electric cylinders 221 of the first cutting assembly 22 and the second cutting assembly 23 work to drive the flame cutting guns 223 at one end thereof to move linearly. The two cutting assemblies cut along the cutting lines on both sides of the elbow body 4 respectively, cutting the elbow body 4 into a specified size. The remaining materials cut off fall into the slag collection tank 3 and are centrally collected by the slag collection tank 3. After cutting is completed, the rotation drive base 11 drives the rotating disk 12 to rotate a certain angle, moving the elbow to be cut into the cutting position and at the same time moving out the cut elbow. The above actions are repeated for continuous cutting.
