Description

A rotary bottom collecting machine Technical Field

[0001] The utility model relates to the technical field of steel cylinder production, in particular to a rotary wheel bottom collecting machine. Background Art

[0002] When industrial gas cylinders are formed at the bottom (i.e., hot spinning of steel pipes), an external introduction device is usually used to guide the cylinder steel pipe into the body of the rotary bottom collecting machine. Inside the body, the cylinder steel pipe is stabilized by the cooperation of support rollers and pressure rollers. During introduction, the cylinder steel pipe will lift up the pressure roller, and the gravity of the pressure roller will press the cylinder steel pipe. However, the cylinder steel pipe will be subjected to various forces during the hot spinning process. It is not stable enough to rely solely on the pressure roller to press the cylinder steel pipe. The cylinder steel pipe is still prone to shaking or warping, which will affect the hot spinning uniformity of the cylinder steel pipe. In view of this, the present application is proposed.

[0004] The utility model proposes a rotary bottom collecting machine, in which a buffer mechanism is arranged at the upper end of a pressing roller. After the gas cylinder steel pipe is introduced, the gas cylinder steel pipe will lift up the pressing roller, and the pressing roller will squeeze the buffer mechanism. When the gas cylinder steel pipe receives various forces during the hot spinning process, the buffer mechanism can buffer the pressing roller, reduce the shaking degree of the gas cylinder steel pipe, and ensure the stable progress of the hot spinning process.

[0048] As shown in FIG1-6, a rotary bottom forming machine is used to perform hot spinning on a gas cylinder steel tube 4, including:

[0049] Machine body 1, spinning device 2, supplementary fire device 3;

[0050] The spinning device 2 is arranged on the outer side of the machine body 1;

[0051] The fire supplement device 3 is arranged on the side of the machine body 1 along the direction of introduction of the gas cylinder steel pipe 4;

[0052] The machine body 1 is provided with a support roller 12, a pressure roller 13, and a buffer mechanism 14;

[0053] The support roller 12 is provided at the lower end of the machine body 1 to support the introduced gas cylinder steel pipe 4;

[0054] The pressing roller 13 is provided at the upper end of the machine body 1 and cooperates with the supporting roller 12 to stabilize the cylinder steel pipe 4;

[0055] One end of the pressing roller 13 is a straight tube and the other end is a tapered surface;

[0056] A rotating shaft 131 is inserted into the interior of the pressing roller 13;

[0057] There is a gap between the rotating shaft 131 and the inner cavity of the pressing roller 13;

[0058] The buffer mechanism 14 is fitted on the upper end of the pressing roller 13 to further stabilize the pressing roller 13 and the cylinder steel pipe 4 .

[0059] Specifically, the gas cylinder steel pipe 4 is introduced into the interior of the machine body 1 through an external introduction device. During the introduction, the gas cylinder steel pipe 4 will squeeze one end of the conical surface of the pressing roller 13. Due to the gap between the rotating shaft 131 and the inner cavity of the pressing roller 13, the pressing roller 13 will be lifted up until the gas cylinder steel pipe 4 enters the straight pipe section of the pressing roller 13. The spinning device 2 will perform a spinning operation on the gas cylinder steel pipe 4, and the fire-adding device 3 will spray fire at the spinning position to achieve the purpose of fire-adding. During the spinning and introduction stage of the gas cylinder steel pipe 4, the pressure roller 13 will be lifted up, and by providing a buffer mechanism 14, the pressure roller 13 will be buffered, and can further stably press the gas cylinder steel pipe 4 to prevent the gas cylinder steel pipe 4 from excessive shaking during spinning, thereby maintaining the stability of spinning and fire-adding.

Buffer portion 142 is elastic, providing a cushioning and shock-absorbing effect. The specific structure of buffer portion 142 is not limited and can be made of a flexible material or a suitable elastic member.

[0064] In some embodiments, a controller 11 is provided on the side of the body 1;

The angle sensor 27 can detect the rotation angle of the rotating plate 22, facilitating the specific control of the re-firing device 3 by the controller 11.

[0075] In some embodiments, the body 1 is provided with an infrared temperature sensor 15;

[0076] The infrared temperature sensor 15 is electrically connected to the supplementary fire device 3 and the controller 11 .

[0077] By adopting the above technical solution, the infrared temperature sensor 15 can detect the temperature of the spinning area of ​​the cylinder steel tube 4 and feed it back to the controller 11 so as to control the specific re-fire operation of the re-fire device 3 through the controller 11.

[0078] In some embodiments, a rear end limiting plate 16 is provided inside the body 1 .

[0079] By adopting the above technical solution, the rear end limit plate 16 can limit the distance of introduction of the gas cylinder steel pipe 4, thereby achieving standardization of production.

[0080] In some embodiments, the supplementary fire device 3 includes a flamethrower 31, a limit block 32, and a guide rail 33;

[0081] The flamethrower 31 is in sliding engagement with the guide rail 33;
