Description

Technical Field

[0001] This utility model relates to the field of steel pipe production technology, specifically a transfer device for the production of small-diameter seamless stainless steel pipes. Background Technology

[0002] Seamless stainless steel pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. It is a type of steel pipe that is resistant to corrosion from weak corrosive media such as air, steam, and water, as well as chemical corrosive media such as acids, alkalis, and salts. It is also known as stainless acid-resistant steel pipe. Seamless stainless steel pipe is not only used for transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts and containers, but it is also an economical steel material. Using seamless stainless steel pipe to manufacture building structural space frames, columns, and mechanical supports can reduce weight and enable factory-based mechanized construction. However, during the production of steel pipes, they need to be transferred between different processing equipment.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Existing steel pipe transfer devices typically stack steel pipes on transfer racks, causing collisions and friction between stainless steel pipes during transfer, which affects the precision of the stainless steel pipes. Therefore, we propose a transfer device for the production of small-diameter seamless stainless steel pipes to solve the above-mentioned problems. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a transfer device for the production of small-diameter seamless stainless steel pipes, including a base plate, a handle installed on one side of the base plate, a roller installed at the bottom of the base plate, and limit grooves opened at both ends of the inner wall of the base plate.

A second threaded rod is sleeved on the inner wall of the first threaded hole. Guide blocks are slidably connected inside the four sliding grooves. Upper pressure plate one and upper pressure plate two are installed on the inner side of the four guide blocks. Pipe groove two is opened at equal intervals at the bottom of upper pressure plate one and upper pressure plate two. The bottom of the second threaded rod is rotatably connected to the top of upper pressure plate two. Two connecting plates are installed at the top of upper pressure plate one and the bottom of upper pressure plate two.

[0007] Preferably, the adjusting mechanism includes a slider and two connecting blocks. The slider is slidably connected to the inner wall of the limiting groove, and the two connecting blocks are installed on the top of the slider. The inner wall of the slider is provided with a second threaded hole, which is sleeved on the outer wall of the first threaded rod.

[0008] Preferably, both the limiting groove and the slider are U-shaped, and the two support frames are installed on the top of the two connecting blocks.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a transfer device for the production of small-diameter seamless stainless steel pipes, including a base plate 1, a handle 2 installed on one side of the base plate 1, a roller 3 installed at the bottom of the base plate 1, and limit grooves 4 opened at both ends of the inner wall of the base plate 1. The inner walls of the two limit grooves 4 are rotatably connected to a first threaded rod 9, and the inner walls of the two limit grooves 4 are slidably connected to an adjustment mechanism. The top of the adjustment mechanism is equipped with two support frames 6, and the inner sides of the two support frames 6 are fixedly connected with two lower clamping plates 7. The tops of the two lower clamping plates 7 are equidistantly provided with multiple pipe grooves 71.

[0023] Two adjustment mechanisms can be installed through the two limiting grooves 4 opened on the inner wall of the base plate 1. Since the inner walls of the two limiting grooves 4 are rotatably connected with the first threaded rods 9, and the two support frames 6 are installed on the top of the adjustment mechanism, the two rotating first threaded rods 9 can drive the two adjustment mechanisms to slide along the inner walls of the two limiting grooves 4 under the action of the threads, so that the lower clamping plate 7 can store steel pipes of different lengths.

[0024] An arch frame 5 is fixedly installed at the center of the top of the base plate 1. Four sliding grooves 51 are opened at the left and right ends of the inner side of the arch frame 5. A first threaded hole 52 is opened at the top of the arch frame 5. A second threaded rod 17 is sleeved on the inner wall of the first threaded hole 52. Guide blocks 14 are slidably connected inside the four sliding grooves 51. Upper pressure plate 1 8 and upper pressure plate 2 81 are installed on the inner side of the four guide blocks 14. Pipe grooves 2 15 are opened at equal intervals at the bottom of upper pressure plate 1 8 and upper pressure plate 2 81. The bottom of the second threaded rod 17 is rotatably connected to the top of upper pressure plate 2 81. Two connecting plates 16 are installed at the top of upper pressure plate 1 8 and the bottom of upper pressure plate 2 81.

[0025] Four guide blocks 14 can be installed through four sliding grooves 51 opened on the inner wall of the arch frame 5. Since upper pressure plate 1 8 and upper pressure plate 2 81 are installed on the inner side of the four guide blocks 14, and two connecting plates 16 are installed on the top of upper pressure plate 1 8 and the bottom of upper pressure plate 2 81, the second threaded rod 17 can be rotated. Under the action of the first threaded hole 52, the upper pressure plate 2 81, the two connecting plates 16 and the upper pressure plate 1 8 can be pushed, which will drive the four guide blocks 14 to move down along the four sliding grooves 51. In this way, the upper pressure plate 1 8 and the upper pressure plate 2 81 can fix the steel pipe and avoid impact and friction between the stainless steel pipes.

[0026] See Figure 1 , Figure 2 The adjustment mechanism includes a slider 11 and two connecting blocks 12. The slider 11 is slidably connected to the inner wall of the limiting groove 4. The two connecting blocks 12 are installed on the top of the slider 11. The inner wall of the slider 11 is provided with a second threaded hole 13. The second threaded hole 13 is sleeved on the outer wall of the first threaded rod 9. The limiting groove 4 and the slider 11 are both U-shaped. Two support frames 6 are installed on the top of the two connecting blocks 12. The multiple tube grooves 71 are all V-shaped. At the same time, the inner walls of the multiple tube grooves 71 are all equipped with rubber pads.

[0027] The two connecting blocks 12 in the adjustment mechanism can be used to install the two support frames 6. Since the inner wall of the slider 11 is provided with a second threaded hole 13, which is sleeved on the outer wall of the first threaded rod 9, the first threaded rod 9 is rotated. Under the action of the second threaded hole 13, the slider 11 can be driven, which in turn drives the two connecting blocks 12, the two support frames 6 and the two lower clamping plates 7 to slide along the inner wall of the two limiting grooves 4. This allows the two lower clamping plates 7 to store steel pipes of different lengths. At the same time, since the multiple pipe grooves 71 are all "V" shaped and the inner walls of the multiple pipe grooves 71 are all equipped with rubber pads, the "V" shape of the pipe grooves 71 can adapt to the shape of the steel pipe, enhance the stability of the connection, and the rubber pads can prevent the steel pipe from directly contacting the pipe grooves 71.

[0028] See Figure 1 , Figure 3 A bearing is installed in the middle of the top of the upper pressure plate 81. The bottom of the second threaded rod 17 is fixedly installed with the bearing. Multiple tube grooves 15 are opened at the bottom of both the upper pressure plate 8 and the upper pressure plate 81. The multiple tube grooves 15 are all in the shape of an inverted "V". Rubber pads are installed on the inner wall of the multiple tube grooves 15. The upper ends of the two connecting plates 16 are fixedly connected to the bottom of the upper pressure plate 81, and the lower ends of the two connecting plates 16 are fixedly connected to the top of the upper pressure plate 8.

[0029] The second threaded rod 17 can be installed through the bearing installed on the top of the upper pressure plate 2 81. Since the upper end of the connecting plate 16 is fixedly connected to the bottom of the upper pressure plate 2 81, and the lower ends of the two connecting plates 16 are fixedly connected to the top of the upper pressure plate 1 8, the second threaded rod 17 can be rotated. Under the action of the thread, the second threaded rod 17 can drive the upper pressure plate 2 81, the two connecting plates 16, the upper pressure plate 1 8, and the four guide blocks 14 to move down along the four sliding grooves 51. This allows the upper pressure plate 1 8 and the upper pressure plate 2 81 to fix the steel pipe on the top of the lower clamping plate 7, thereby avoiding impact and friction between the stainless steel pipes. Furthermore, since the multiple pipe grooves 2 15 are all inverted "V" shape, and the inner walls of the multiple pipe grooves 2 15 are all equipped with rubber pads, the inverted "V" shape of the pipe grooves 2 15 can provide uniform pressure to the steel pipe, and the rubber pads can prevent the steel pipe from being damaged due to friction or excessive pressure.

[0030] During operation, two adjustment mechanisms can be installed through the two limiting grooves 4 opened on the inner wall of the base plate 1. Since the inner walls of the two limiting grooves 4 are rotatably connected with first threaded rods 9, and the two support frames 6 are installed on the top of the adjustment mechanism, the two rotating first threaded rods 9 can drive the two adjustment mechanisms to slide along the inner walls of the two limiting grooves 4 under the action of the threads, so that the lower clamping plate 7 can store steel pipes of different lengths.

[0031] Four guide blocks 14 can be installed through four sliding grooves 51 opened on the inner wall of the arch frame 5. Since upper pressure plate 1 8 and upper pressure plate 2 81 are installed on the inner side of the four guide blocks 14, and two connecting plates 16 are installed on the top of upper pressure plate 1 8 and the bottom of upper pressure plate 2 81, the second threaded rod 17 can be rotated. Under the action of the first threaded hole 52, the upper pressure plate 2 81, the two connecting plates 16 and the upper pressure plate 1 8 can be pushed, which will drive the four guide blocks 14 to move down along the four sliding grooves 51. In this way, the upper pressure plate 1 8 and the upper pressure plate 2 81 can fix the steel pipe and avoid impact and friction between the stainless steel pipes.

[0032] The two connecting blocks 12 in the adjustment mechanism can be used to install the two support frames 6. Since the inner wall of the slider 11 is provided with a second threaded hole 13, which is sleeved on the outer wall of the first threaded rod 9, the first threaded rod 9 is rotated. Under the action of the second threaded hole 13, the slider 11 can be driven, which in turn drives the two connecting blocks 12, the two support frames 6 and the two lower clamping plates 7 to slide along the inner wall of the two limiting grooves 4. This allows the two lower clamping plates 7 to store steel pipes of different lengths. At the same time, since the multiple pipe grooves 71 are all "V" shaped and the inner walls of the multiple pipe grooves 71 are all equipped with rubber pads, the "V" shape of the pipe grooves 71 can adapt to the shape of the steel pipe, enhance the stability of the connection, and the rubber pads can prevent the steel pipe from directly contacting the pipe grooves 71.

[0033] The second threaded rod 17 can be installed through the bearing installed on the top of the upper pressure plate 2 81. Since the upper end of the connecting plate 16 is fixedly connected to the bottom of the upper pressure plate 2 81, and the lower ends of the two connecting plates 16 are fixedly connected to the top of the upper pressure plate 1 8, the second threaded rod 17 can be rotated. Under the action of the thread, the second threaded rod 17 can drive the upper pressure plate 2 81, the two connecting plates 16, the upper pressure plate 1 8, and the four guide blocks 14 to move down along the four sliding grooves 51. This allows the upper pressure plate 1 8 and the upper pressure plate 2 81 to fix the steel pipe on the top of the lower clamping plate 7, thereby avoiding impact and friction between the stainless steel pipes. Furthermore, since the multiple pipe grooves 2 15 are all inverted "V" shape, and the inner walls of the multiple pipe grooves 2 15 are all equipped with rubber pads, the inverted "V" shape of the pipe grooves 2 15 can provide uniform pressure to the steel pipe, and the rubber pads can prevent the steel pipe from being damaged due to friction or excessive pressure.

[0034] In summary, the two lower clamping plates 7 of this device can store steel pipes, and by rotating the second threaded rod 17, the upper pressure plate 2 81, the two connecting plates 16 and the upper pressure plate 1 8 are pushed, which drives the four guide blocks 14 to move down along the four sliding grooves 51, so that the upper pressure plate 1 8 and the upper pressure plate 2 81 can fix the steel pipes, thereby avoiding impact and friction between stainless steel pipes.
