Technical Field

[0001] The utility model belongs to the technical field of stainless steel pipe straightening, and particularly relates to a stainless steel pipe straightening machine. Background Technique

[0002] Stainless steel pipes are a kind of hollow long round steel, which are mainly widely used in industrial conveying pipelines such as petroleum, chemical industry, medical treatment, food, light industry, machinery and instruments, as well as mechanical structure parts, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchen utensils, etc.

[0003] After the existing stainless steel pipes are manufactured, the pipes need to be straightened. However, the existing pipe straightening effect is poor. When the pipes are being straightened, there will still be a slight bend in the middle of the stainless steel pipes, resulting in a poor pipe straightening effect. Moreover, the existing stainless steel pipe correction does not have a guiding effect, so manual conveying and guiding are still required, further resulting in poor practicability.

[0004] Therefore, a stainless steel pipe straightening machine is needed to solve the problems of poor pipe straightening effect and the need for manual conveying and guiding in the prior art. Content of the Utility Model

Specific embodiments

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] Please refer to Figures 1-4 , the present utility model provides a stainless steel pipe straightening machine, including a support plate 1 and a bracket 3. A top plate 2 is arranged at the top end of the support plate 1. The support plate 1 and the top plate 2 are fixedly connected through the bracket 3. A servo cylinder 4 is fixed at the center of the top end of the top plate 2. The driving end of the servo cylinder 4 is fixed with a mounting piece 5. A straightening mechanism 6 is arranged at the bottom end of the mounting piece 5;

[0023] At both ends of the inner wall of the support plate 1, a plurality of movable grooves 7 are arranged in parallel. Movable blocks 8 are movably installed on the inner walls of the plurality of movable grooves 7. A threaded screw rod 11 is threadedly connected to the center of one of the movable blocks 8. A connecting rod 9 is rotatably installed on the opposite side of the movable block 8. A guiding roller 10 is fixed at the center of the connecting rod 9. A driving motor 13 is fixed on the outer wall of one side of the support plate 1. The driving end of the driving motor 13 is fixed with a mounting rod 14. The other end of the mounting rod 14 is provided with a transmission mechanism 15.

[0024] The straightening mechanism 6 can mainly straighten the stainless steel pipe, thereby improving the straightening effect of the stainless steel pipe.

[0025] The transmission mechanism 15 can mainly drive two mounting rods 14 to rotate simultaneously, thereby driving two guiding balls 16 to rotate, so as to guide the stainless steel pipe to move, and further improving the practicability of the straightening machine.

[0026] Furthermore, as Figure 2 shown, it is specifically noted that the straightening mechanism 6 includes two rotating rods 61. The two rotating rods 61 are rotatably installed on the inner wall of the mounting piece 5. The bottom ends of the rotating rods 61 are rotatably installed with rotating pieces 62. A transmission rod 63 is rotatably installed between the bottoms of the two rotating pieces 62. A straightening roller 64 is fixed in the middle of the transmission rod 63. Limiting pulleys 65 are arranged at both ends of the transmission rod 63.

[0027] First, the stainless steel pipe is conveyed from one end of the guiding ball 16 to the surface of the guiding roller 10 for preliminary conveyance. Meanwhile, by starting the servo cylinder 4, the mounting member 5 can be driven, and then the straightening mechanism 6 can be driven to operate. Meanwhile, by applying force to the rotating rod 61, the rotating member 62 can be driven to rotate and be stressed, thereby driving the transmission rod 63 to rotate towards both sides, enabling the straightening rollers 64 to be in contact with the surface of the steel pipe. Then, by applying force to the straightening rollers 64 towards both sides, the steel pipe can be straightened, thereby improving the straightening effect of the steel pipe. Meanwhile, to improve the practicality of steel pipe straightening, by rotating the threaded lead screw 11, the movable block 8 can be driven to move up and down. By the up and down movement of the movable block 8, the connecting rod 9 can be driven to move up and down and be stressed, thereby driving the guiding roller 10 to be adjusted up and down, enabling steel pipes of different diameters to be straightened.

[0028] Further, as Figure 1 shown, it is specifically noted that the transmission mechanism 15 includes a driving gear 151 and a driven gear 152. The driving gear 151 and the driven gear 152 are respectively fixed to one end of two mounting rods 14, and the driving gear 151 and the driven gear 152 are meshed with each other.

[0029] When the driving motor 13 is started, the mounting rod 14 can be driven to rotate. Then, mainly through the mounting rod 14, the driving gear 151 and the driven gear 152 can be driven to rotate, thereby driving the guiding ball 16 to rotate, and thus driving the steel pipe to be guided and straightened.

[0030] The working process of this solution is as follows: First, the steel pipe is conveyed from one side of the guiding ball 16 between the guiding roller 10 and the straightening rollers 64. Then, by starting the driving motor 13, the mounting rod 14 can be driven to rotate. Through the mounting rod 14, the driving gear 151 and the driven gear 152 can be driven to rotate simultaneously, and then the guiding ball 16 can be driven to rotate simultaneously, thereby guiding and conveying the steel pipe. Meanwhile, by starting the servo cylinder 4, the mounting member 5 can be driven, and then the rotating rod 61 can be driven to rotate, and then the rotating member 62 can be driven to rotate, thereby driving the transmission rod 63 to rotate. Further, the straightening rollers 64 can be made to fit more closely to the surface of the steel pipe, enabling the steel pipe to be straightened.

[0031] According to the above working process, it can be known that by rotating the threaded lead screw 11, the movable block 8 can be driven to move in a threaded manner. The movable block 8 can mainly drive the connecting rod 9 to move, and then drive the guide roller 10 to move up and down, so as to adjust the placement of the steel pipe, and thus improve the straightening effect of the steel pipe.

[0032] Furthermore, as Figure 1 shown, it is specifically noted that guide balls 16 are fixedly installed in the middle of the mounting rods 14.

[0033] The guide balls 16 can mainly guide and convey the steel pipe, thereby improving the conveying effect of the steel pipe and further improving the straightening effect of the steel pipe.

[0034] Furthermore, as Figure 1 、 Figure 3 and Figure 4 shown, it is specifically noted that limiting sliding grooves 12 are opened at both ends of the inner wall of the support plate 1, and limiting pulleys 65 are slidably installed on the inner wall of the limiting sliding grooves 12.

[0035] Furthermore, as Figure 1 、 Figure 3 and Figure 4 shown, it is specifically noted that support legs 17 are fixedly installed at the bottom end of the support plate 1.

[0036] In summary, the straightening mechanism 6 can mainly straighten the stainless steel pipe, thereby improving the straightening effect of the stainless steel pipe. The transmission mechanism 15 can mainly drive the two mounting rods 14 to rotate simultaneously, and then drive the two guide balls 16 to rotate, so as to guide the stainless steel pipe to move, and further improve the practicability of the straightening machine.

[0037] The drive motor 13 can be purchased on the market. The drive motor 13 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
