[0009] Preferably, the groove and the mounting seat are in sliding connection, and the screw rod is adapted to the mounting groove.

[0010] Through the above technical solution, the mounting seat is provided with the groove. When installing the mounting seat, insert the mounting seat from the lower end of the screw rod for quick installation. The screw rod is in threaded connection with the seat plate. When the stainless steel pipe needs to be straightened, according to the diameter of the stainless steel pipe, rotate the screw rod to drive the mounting seat to move along the groove until the first straightening wheel and the second straightening wheel are adapted to the stainless steel pipe, which is simple to adjust.

[0012] Through the above technical solution, the diameter of the first straightening wheel is larger than that of the second straightening wheel. When straightening, the stainless steel pipe is passed through between the first straightening wheel and the second straightening wheel and then passes through the straightening holes of the straightening plate. As the stainless steel pipe is pulled, the first straightening wheel and the second straightening wheel straighten the stainless steel pipe. The larger diameter of the first straightening wheel applies a greater pressure or force on the surface of the stainless steel pipe to initially straighten the pipe material, gradually flatten or adjust the irregularities or bends on the surface of the pipe material to make it more straight. The two first straightening wheels apply pressure from both sides to further refine the surface quality of the pipe material during the straightening process and make fine adjustments to the surface of the pipe material to ensure that the final form of the pipe material is as straight and precise as possible.

[0017] Preferably, the transverse groove is slidably connected to the guide rail, both sides of the guide groove are inclined structures, the guide groove is adapted to the second clamping block, and both ends of the spring are fixedly connected to the fixed column and the upright column respectively.

[0018] Through the above technical solution, when the stainless steel pipe is inserted into the guide groove, the stroke of the second cylinder is shortened to drive the moving block to move backward, and the second clamping block moves backward accordingly. The second clamping block is squeezed by the guide grooves on both sides, and the second clamping block moves from both sides to the center until the stainless steel pipe is clamped.

[0019] Preferably, both the second sliding rod and the second sliding rod are slidably connected to the pull rod, the long groove is slidably connected to the inclined block, and engaging teeth are provided on the inner sides of both the first clamping block and the second clamping block.

[0020] Through the above technical solution, while the clamp block 2 moves, the clamp block 1 is pulled by the pull rod to move along the long groove, and the two clamp blocks 1 move from top to bottom toward the center until the stainless steel pipe is clamped. The two clamping structures enable the stainless steel pipe to receive clamping forces in multiple directions, and the clamping effect is good. The biting teeth set in the clamp block 1 and the clamp block 2 bite the stainless steel pipe. As the stainless steel pipe is pulled backward, the biting effect of the biting teeth is better, thereby improving the stretching and straightening effect. Slide bar 2, slide bar 2 and pull rod are set, so that the movement of the clamp block 2 can drive the movement of the clamp block 1, and only a single cylinder is required for clamping, and the structure is simple.

[0021] Preferably, the slide rail and the slide groove are slidably connected, the chain and the fixed claw are fixedly connected, and the drive shaft and the chain are meshingly connected.

[0022] Through the above technical solution, after the stainless steel pipe is clamped, the reduction motor is started to drive the drive shaft to rotate, and the drive shaft drives the chain to rotate, thereby driving the clamping assembly and the stainless steel pipe to move backward for straightening operations.

[0023] Preferably, the collecting frame comprises a frame body, a handle and a pulley, the handles are fixedly connected to the front and rear ends of the frame body, the pulley is fixedly connected to the lower end of the frame body, and the frame body corresponds to the guide inclined surface.

[0024] Through the above technical scheme, a collection frame is set up. After the stainless steel pipe is straightened and cut, the second stroke of the cylinder is increased, and the spring drives the second and first clamps to reset. The clamping assembly is separated from the stainless steel pipe. Under the action of gravity, the stainless steel pipe falls into the collection frame along the guide slope. The handle can be pulled to transfer the straightened stainless steel pipe, which is very practical.

[0025] Compared with the prior art, the utility model provides a stainless steel pipe straightening machine, which has the following beneficial effects:

[0026] 1. In the stainless steel pipe straightening machine, when the clamping assembly clamps the stainless steel pipe, when the stainless steel pipe is inserted into the guide groove, the stroke of the second cylinder is shortened, driving the moving block to move backward, and the second clamping block moves backward accordingly. The second clamping block is squeezed by the guide grooves on both sides, and the second clamping block moves toward the center from both sides until the stainless steel pipe is clamped. While the second clamping block moves, the first clamping block is pulled along the long groove by the pull rod, and the two first clamping blocks move from top to bottom to the center until the stainless steel pipe is clamped. The two clamping structures make the stainless steel pipe subject to clamping forces in multiple directions, and the clamping effect is good. The bite teeth set in the first clamping block and the second clamping block bite the stainless steel pipe. As the stainless steel pipe is pulled backward, the bite effect of the bite teeth is better, thereby improving the effect of stretching and straightening.

[0027] 2. For this stainless steel pipe straightening machine, the diameter of straightening wheel 1 is larger than that of straightening wheel 2. When straightening, the stainless steel pipe is passed through between straightening wheel 1 and straightening wheel 2 and then out through the straightening holes of the straightening plate. As the stainless steel pipe is pulled, straightening wheel 1 and straightening wheel 2 straighten the stainless steel pipe. With a larger diameter, straightening wheel 1 applies a greater pressure or force on the surface of the stainless steel pipe to preliminarily straighten the pipe material, gradually flatten or adjust the irregularities or bends on the pipe surface to make it more straight. Two straightening wheels 1 apply pressure from both sides to further refine the surface quality of the pipe material during the straightening process and make fine adjustments to the pipe surface to ensure that the final shape of the pipe is as straight and precise as possible. In cooperation with the straightening plate, the straightening effect is good.

[0028] 3. For this stainless steel pipe straightening machine, the mounting seat is provided with a groove. When installing the mounting seat, it is inserted and connected from the lower end of the screw, with a fast installation speed. The screw is threadedly connected to the seat plate. When the stainless steel pipe needs to be straightened, according to the diameter of the stainless steel pipe, the screw is rotated to drive the mounting seat to move along the groove until straightening wheel 1 and straightening wheel 2 are adapted to the stainless steel pipe, and the adjustment is simple.

[0029] 4. For this stainless steel pipe straightening machine, after clamping the stainless steel pipe, the reduction motor is started to drive the drive shaft to rotate. The drive shaft drives the chain to rotate, thereby driving the clamping assembly and the stainless steel pipe to move backward for straightening operations. A rotating seat and a cutting machine are provided. When the straightened stainless steel pipe reaches an appropriate length, the stroke of cylinder 1 is increased to drive the rotating seat to rotate until the blade of the cutting machine contacts the stainless steel pipe to cut the stainless steel pipe. The structure is simple and a conventional small cutting device can be used, which is convenient for production. A collection box is provided. After the stainless steel pipe is straightened and cut, the stroke of cylinder 2 is increased, and with the cooperation of the spring, it drives clamp block 2 and clamp block 1 to reset, separating the clamping assembly from the stainless steel pipe. Under the action of gravity, the stainless steel pipe falls into the collection box along the guiding inclined plane. The straightened stainless steel pipe can be transported by pulling the handle, which is very practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Specifically, the straightening assembly 3 includes a seat plate 301, a groove 302, a fixing plate 303, a screw 304, a mounting seat 305, a mounting groove 306, a first straightening wheel 307 and a second straightening wheel 308. The upper end of the seat plate 301 is provided with the groove 302. The upper end of the seat plate 301 is fixedly connected with the fixing plate 303. The two sides of the seat plate 301 are provided with the screws 304. The inside of the groove 302 is provided with the mounting seat 305. The upper end of the mounting seat 305 is provided with the mounting groove 306. The upper end of the mounting seat 305 is provided with the first straightening wheel 307 and the second straightening wheel 308. The advantage is that the straightening assembly 3 is provided to apply pressure to both sides of the stainless steel pipe to be straightened, improving the straightening effect.

[0045] Specifically, the groove 302 is slidably connected to the mounting seat 305, and the screw 304 is adapted to the mounting groove 306. The advantage is that the groove 302 is provided on the mounting seat 305. When installing the mounting seat 305, the mounting seat 305 is inserted and connected from the lower end of the screw 304, and the installation speed is fast. The screw 304 is threadedly connected to the seat plate 301. When the stainless steel pipe needs to be straightened, according to the diameter of the stainless steel pipe, the screw 304 is rotated to drive the mounting seat 305 to move along the groove 302 until the straightening wheel 307 and the straightening wheel 308 are adapted to the stainless steel pipe, and the adjustment is simple.

[0046] Specifically, the diameter of the straightening wheel 307 is larger than that of the straightening wheel 308, and the screw 304 is threadedly connected to the seat plate 301. The advantage is that the diameter of the straightening wheel 307 is larger than that of the straightening wheel 308.

The two straightening wheels 307 apply pressure from both sides, further refining the surface quality of the pipe material during the straightening process, making fine adjustments to the surface of the pipe material to ensure that the final shape of the pipe material is as straight and precise as possible. Cooperating with the straightening plate 7, the straightening effect is good.

[0047] Embodiment 2: As Figure 2-10 shown, as an improvement over the previous embodiment

[0048] Specifically, the rotating seat 13 is rotatably connected to the straightening seat 5, and the blade of the cutting machine 14 corresponds to the straightening plate 7. The advantage is that the rotating seat 13 and the cutting machine 14 are provided. When the straightened stainless steel pipe reaches an appropriate length, the stroke of the first cylinder 12 is increased to drive the rotating seat 13 to rotate until the blade of the cutting machine 14 contacts the stainless steel pipe and cuts the stainless steel pipe. The structure is simple, and a conventional small cutting device can be used, which is convenient for production.

[0049] Specifically, the telescopic rod 1506 is fixedly connected to the moving block 1524, and the telescopic rod 1506 is slidably connected to the clamping seat 1509. The advantage is that the telescopic rod 1506 and the moving block 1524 are provided. When the clamping assembly 15 clamps the stainless steel pipe, the stroke of the second cylinder 1505 is shortened to drive the moving block 1524 to move backward, converting the backward pulling force into lateral and vertical clamping forces, and the structure is reasonable.

[0050] Specifically, the horizontal groove 1525 is slidably connected to the guide rail 1522. Both sides of the guiding groove 1512 are inclined structures. The guiding groove 1512 is adapted to the second clamping block 1520. Both ends of the spring 1519 are fixedly connected to the fixed column 1518 and the upright column 1521 respectively. The advantage is that when the stainless steel pipe is inserted into the guiding groove 1512, the stroke of the second air cylinder 1505 is shortened, driving the moving block 1524 to move backward. The second clamping block 1520 moves backward accordingly. The second clamping block 1520 is squeezed by the guiding grooves 1512 on both sides, and the second clamping block 1520 moves from both sides to the center until the stainless steel pipe is clamped.

[0051] Embodiment 3: As Figure 2-10 shown, as an improvement over the previous embodiment.

[0052] Specifically, both the second sliding rods 1523 are slidably connected to the pull rod 1517. The long groove 1513 is slidably connected to the inclined block 1515. Biting teeth are provided on the inner sides of both the first clamping block 1514 and the second clamping block 1520. The advantage is that while the second clamping block 1520 moves, the first clamping block 1514 is pulled along the long groove 1513 through the pull rod 1517. The two first clamping blocks 1514 move from top and bottom to the center until the stainless steel pipe is clamped. With two clamping structures, the stainless steel pipe is subjected to clamping forces in multiple directions, and the clamping effect is good. The biting teeth provided on the first clamping block 1514 and the second clamping block 1520 bite the stainless steel pipe tightly. As the stainless steel pipe is pulled backward, the biting effect of the biting teeth is better, thereby improving the stretching and straightening effect. The second sliding rods 1523 and the pull rod 1517 are provided, enabling the second clamping block 1520 to drive the first clamping block 1514 to move while moving. Only a single air cylinder is required for clamping, and the structure is simple.

[0053] Specifically, the slide rail 9 is slidably connected to the chute 1502. The chain 16 is fixedly connected to the fixed claw 1503. The drive shaft 19 is meshed with the chain 16. The advantage is that after the stainless steel pipe is clamped, the reduction motor 18 is started to drive the drive shaft 19 to rotate. The drive shaft 19 drives the chain 16 to rotate, thereby driving the clamping assembly 15 and the stainless steel pipe to move backward for straightening operation.

[0054] Specifically, the collection box 20 includes a box body 2001, a handle 2002 and a pulley 2003. The handle 2002 is fixedly connected to the front and rear ends of the box body 2001. The pulley 2003 is fixedly connected to the lower end of the box body 2001. The box body 2001 corresponds to the guiding inclined plane 10. The advantage is that the collection box 20 is provided. After the stainless steel pipe is straightened and cut, the stroke of the second air cylinder 1505 is increased, and the second clamping block 1520 and the first clamping block 1514 are driven to reset in cooperation with the spring 1519. The clamping assembly 15 is separated from the stainless steel pipe. Under the action of gravity, the stainless steel pipe falls into the collection box 20 along the guiding inclined plane 10. The handle 2002 can be pulled to transfer the straightened stainless steel pipe, which is very practical.

[0055] Working principle: When in use, insert the mounting base 305 from the lower end of the screw 304 for connection. The installation speed is fast. The screw 304 is threadedly connected to the seat plate 301. When it is necessary to straighten the stainless steel pipe, according to the diameter of the stainless steel pipe, rotate the screw 304 to drive the mounting base 305 to move along the groove 302 until the straightening wheel one 307 and the straightening wheel two 308 are adapted to the stainless steel pipe. Pass the stainless steel pipe through between the straightening wheel one 307 and the straightening wheel two 308 and out through the straightening hole of the straightening plate 7. When the stainless steel pipe is inserted into the internal part of the guiding groove 1512, shorten the stroke of the cylinder two 1505 to drive the moving block 1524 to move backward, and the clamping block two 1520 moves backward accordingly. The clamping block two 1520 is squeezed by the guiding grooves 1512 on both sides, and the clamping block two 1520 moves from both sides to the center until the stainless steel pipe is clamped. While the clamping block two 1520 moves, the clamping block one 1514 is pulled along the long groove 1513 through the pull rod 1517, and the two clamping blocks one 1514 move from top and bottom to the center until the stainless steel pipe is clamped. The two clamping structures enable the stainless steel pipe to receive clamping forces from multiple directions, and the clamping effect is good. After clamping the stainless steel pipe, start the reduction motor 18 to drive the drive shaft 19 to rotate. The drive shaft 19 drives the chain 16 to rotate, thereby driving the clamping assembly 15 and the stainless steel pipe to move backward for straightening operation. The engaging teeth provided on the clamping block one 1514 and the clamping block two 1520 bite the stainless steel pipe tightly. As the stainless steel pipe is pulled backward, the engaging effect of the engaging teeth is better, thereby improving the stretching and straightening effect. As the stainless steel pipe is pulled, the straightening wheel one 307 and the straightening wheel two 308 straighten the stainless steel pipe. The diameter of the straightening wheel one 307 is larger, applying a greater pressure or force on the surface of the stainless steel pipe to initially straighten the pipe material, gradually flatten or adjust the irregularities or bends on the surface of the pipe material to make it more straight. The two straightening wheels one 307 apply pressure from both sides to further refine the surface quality of the pipe material during the straightening process, making fine adjustments to the surface of the pipe material to ensure that the final shape of the pipe material is as straight and precise as possible. Cooperating with the straightening plate 7, the straightening effect is good. When the straightened stainless steel pipe reaches an appropriate length, increase the stroke of the cylinder one 12 to drive the rotating seat 13 to rotate until the blade of the cutting machine 14 contacts the stainless steel pipe and cut the stainless steel pipe. The structure is simple and a conventional small cutting device can be used, which is convenient for production. After the stainless steel pipe is straightened and cut, increase the stroke of the cylinder two 1505, and cooperate with the spring 1519 to drive the clamping block two 1520 and the clamping block one 1514 to reset, and the clamping assembly 15 is separated from the stainless steel pipe. Under the action of gravity, the stainless steel pipe falls into the collection frame 20 along the guiding inclined plane 10. The straightened stainless steel pipe can be transported by pulling the handle 2002. It is very practical.
