Description

Technical Field

[0001] The utility model relates to the technical field of annealing, and more specifically, to a stainless steel pipe annealing device. Background Art

[0002] Annealing is a metal heat treatment process, which means slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at a suitable temperature. The purpose is to reduce hardness, improve deep processing performance; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust structure, and eliminate structural defects.

[0003] At present, a Chinese patent with a publication (announcement) number of CN220468069U discloses a continuous annealing device for seamless steel pipes, which includes an annealing machine body, a supporting device is provided on one side of the outer surface of the annealing machine body, a cleaning device is provided on one side of the outer surface of the annealing machine body, the supporting device includes a rectangular block fixedly connected to one side of the outer surface of the annealing machine body, a rectangular groove is provided on the right side of the rectangular block, and a threaded rod is provided on the inner wall of the rectangular groove. When the above-mentioned continuous annealing device for seamless steel pipes is used, the motor is started to offset the support rods at both ends. Since the operating block and the support rod are fixedly connected, the operating block is adjusted according to the number of steel pipes, so that the operating blocks at both ends clamp the steel pipes, thereby achieving the effect of clamping the steel pipes to solve the problem that "slippage may occur between the steel pipe and the transmission shaft, causing the steel pipe to deviate, and then causing the steel pipe to be unable to enter the quenching room". However, the device realizes clamping and limiting the steel pipe through the force between the operating block and the transmission shaft, but since the clamping direction of the operating block is perpendicular to the transmission direction of the transmission roller, it is impossible to limit the steel pipe while it is being transmitted, resulting in poor practicality.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2 As shown, a stainless steel pipe annealing device of an embodiment of the utility model includes an annealing machine body 1 and a feeding channel 10 is formed in the annealing machine body. The annealing machine body 1 is provided with a conveying mechanism 2 at the inlet and outlet of the feeding channel 10. The conveying mechanism 2 is used to drive the stainless steel pipe in and out of the feeding channel 10 to realize annealing processing. The conveying mechanism 2 includes a support frame 3 and a plurality of power rollers 30 are installed side by side on the support frame 3 and are evenly distributed at equal distances. A limiting component is also provided on the support frame 3, and the limiting component is used to limit the stainless steel pipe above the support frame 3.

[0019] When in use, the stainless steel pipe to be annealed is placed above the conveying mechanism 2 on the inlet side of the feed channel 10, and the power roller 30 is connected to the driving mechanism to drive the stainless steel pipe along the support frame 3 to be conveyed to the feed channel 10 of the annealing machine body 1 and annealing is realized, and then it is transmitted to the outside of the annealing machine body 1 by the conveying mechanism 2 on the outlet side of the feed channel 10. A limiting component is arranged above the conveying mechanism 2, and the steel pipe on the conveying mechanism 2 is limited by the limiting component to avoid slipping between the steel pipe and the transmission shaft, causing the steel pipe to deviate and thus causing the steel pipe to be unable to enter the quenching room.

[0020] The limiting assembly includes two base plates 31 correspondingly arranged on the inner side of the support frame 3 , and a limiting baffle 32 is arranged on the upper end of the base plate 31 and between each adjacent power roller 30 , and the top surface height of the limiting baffle 32 is higher than the top surface height of the power roller 30 .

[0021] When in use, the top surface height of each limit baffle 32 is higher than the top surface height of the power roller 30 , thereby blocking the steel pipe and preventing the steel pipe from erroneously sliding or falling from above the support frame 3 .

[0022] An accommodating recess 33 is formed on the inner side of the limiting baffle 32 , and an auxiliary roller 34 is rotatably arranged in the accommodating recess 33 .

[0023] When in use, the auxiliary roller 34 is provided to reduce the friction coefficient between the limit baffle 32 and the contact side of the steel pipe, thereby avoiding the steel pipe from being stuck due to the existence of the limit baffle 32 and ensuring the smooth transmission of the steel pipe.

[0024] Two guide rods 35 are correspondingly arranged at the two base plates 31 on the inner side of the support frame 3 , and the two base plates 31 are slidably matched with the two guide rods 35 .

[0025] When in use, the two base plates 31 can slide toward or away from each other along the guide rod 35 to adjust the distance between the base plates 31 on both sides, and then adjust the limit interval formed between the limit baffles 32 above the base plates 31 on both sides to adapt to the transmission of different sizes or multiple steel pipes.

[0026] A screw rod 36 is rotatably arranged at the center of the two base plates 31 on the inner side of the support frame 3. The two ends of the screw rod 36 located on the inner side of the support frame 3 have two threaded sections 37 with opposite rotation directions. A nut piece 38 adapted to the two threaded sections 37 is arranged in the center of the two base plates 31; one end of the screw rod 36 extends through the outside of the support frame 3 and is connected to a rotating wheel 39.

[0027] During use, when it is necessary to adjust the spacing between the two side substrates 31, the rotating wheel 39 is rotated forward or reversely to drive the screw rod 36 to rotate. The screw rod 36 rotates through the threaded cooperation between the corresponding nut parts 38 on the two substrates 31 and the two threaded segments 37, as well as the guiding cooperation between the two substrates 31 and the guide rod 35, driving the two substrates 31 to move toward or away from each other to achieve position adjustment.

[0028] The support frame includes two bottom plates 4 , a plurality of support rods 40 equidistantly and spaced apart above the bottom plates 4 , and side plates 41 disposed above each support rod 40 . Each power roller 30 is installed together above the two side plates 41 .

[0029] When in use, the support rod 40 includes a bottom plate 4, a support rod 40 and a side plate 41, which effectively ensures its overall strength.

[0030] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
