[0033] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0034] A pipe material pulling device 100 according to an embodiment of the present application is described below.

[0035] Referring toFigures 1 to 7 The pipe material pulling device 100 of the embodiment of the utility model, including conveying frame 1, first pulling assembly 2 and second pulling assembly 3.

[0036] Conveying frame 1 is used to carry pipe material, and the pipe material can move on the conveying frame 1, so that the turnover of the rolled pipe material is realized, and subsequent cutting operation is facilitated.

[0037] The first pulling assembly 2 is located at the middle part of the conveying frame 1 to pull the pipe material to move along the conveying frame 1, and the first pulling assembly 2 comprises a first frame body 21, a first wheel body 22, a second wheel body 23 and a first driver 24, the first wheel body 22 and the second wheel body 23 are oppositely arranged in the first direction and are both connected to the first frame body 21, a gap is formed between the first wheel body 22 and the second wheel body 23, and the pipe material can pass through the gap. At least one of the first wheel body 22 and the second wheel body 23 is movable along the first direction on the first frame body 21. The first driver 24 is connected to the first frame body 21 and is in transmission connection with at least one of the first wheel body 22 and the second wheel body 23. For example, the first driver 24 is connected to both the first wheel body 22 and the second wheel body 23, and the first wheel body 22 and the second wheel body 23 are both driving wheels. For another example, the first driver 24 is connected to the first wheel body 22, and at this time, the first wheel body 22 is a driving wheel, and the second wheel body 23 is a driven wheel. It can be understood that after the pipe material on the conveying frame 1 is fed to the gap between the first wheel body 22 and the second wheel body 23, the first wheel body 22 and the second wheel body 23 are close to each other and clamp the pipe material, and under the action of the first driver 24, the first wheel body 22 and the second wheel body 23 rotate and exert a pulling force on the pipe material, so that the pipe material is pulled.

[0038] The second pulling assembly 3 is located at the discharging end of the conveying frame 1 to pull the pipe material away from the first pulling assembly 2. It can be understood that, as shown in Figure 1 The rolled pipe material moves on the conveying frame 1 from right to left, and the first pulling assembly 2 can continuously pull the pipe material to move to the left. When single rolling is finished, the second pulling assembly 3 can further convey the pipe material to the left side, so that the pipe material is separated from the first pulling assembly 2 and further moves to the left.

[0039] The second pulling assembly 3 comprises a second frame body 31, a third wheel body 32, a fourth wheel body 33 and a second driver 34. The third wheel body 32 and the fourth wheel body 33 are oppositely arranged in the second direction and are both connected to the second frame body 31. At least one of the third wheel body 32 and the fourth wheel body 33 is movable on the second frame body 31 in the second direction. The second driver 34 is connected to the second frame body 31 and is in driving connection with at least one of the third wheel body 32 and the fourth wheel body 33. For example, the second driver 34 is connected to both the third wheel body 32 and the fourth wheel body 33, and the third wheel body 32 and the fourth wheel body 33 are both driving wheels. For another example, the second driver 34 is connected to the third wheel body 32, and the third wheel body 32 is a driving wheel while the fourth wheel body 33 is a driven wheel. It can be understood that, after the pipe material on the pipe conveying frame 1 is fed between the third wheel body 32 and the fourth wheel body 33, the third wheel body 32 and the fourth wheel body 33 are close to each other and clamp the pipe material. Under the action of the second driver 34, the third wheel body 32 and the fourth wheel body 33 rotate and exert a pulling force on the pipe material, so as to realize pulling. In a normal case, the first pulling assembly 2 and the second pulling assembly 3 can simultaneously pull the pipe material. When the pipe material after rolling is finished and the tail of the pipe material passes through the gap between the first wheel body 22 and the second wheel body 23, only the second pulling assembly 3 pulls the pipe material, and the pipe material is separated from the first pulling assembly 2 and further moves to the left.

[0040] The first direction is orthogonal to the pipe conveying direction of the pipe conveying frame, and the second direction is orthogonal to the vertical direction and the pipe conveying direction of the pipe conveying frame. The first pulling assembly is located in the middle of the pipe conveying frame to pull the pipe material to move along the pipe conveying frame. The second pulling assembly is located downstream of the first pulling assembly to pull the pipe material to separate from the first pulling assembly.

[0041] The first direction and the second direction are orthogonal to the pipe conveying direction (the axial direction of the pipe material) of the pipe conveying frame 1. Therefore, the first direction and the second direction can be the front-back direction or the up-down direction. Specifically, the first direction and the second direction can be the same, for example, both the first direction and the second direction are the front-back direction. Preferably, the first direction and the second direction can be orthogonal. The first direction is parallel to the vertical direction, that is, the first direction is the up-down direction shown in the figure, and the second direction is the front-back direction shown in the figure. In the pulling process, the first wheel body 22 and the second wheel body 23 can clamp the pipe material in the up-down direction, and the third wheel body 32 and the fourth wheel body 33 can clamp the pipe material in the front-back direction, so as to ensure the stable movement of the pipe material in the pipe conveying frame 1.

[0042] It can be understood that, in order to avoid interference of the third wheel body 32 and the fourth wheel body 33 in subsequent operations, the third wheel body 32 and the fourth wheel body 33 are arranged in the front-rear direction instead of the up-down direction, facilitating the pipe to be taken out from the conveying frame 1. Since the pipe after rolling needs to be cut off, when the pipe is separated from the first pulling assembly 2, it can stably enter the next process, avoiding that the pipe is partially overlapped on the equipment of the next process and partially located between the first wheel body and the second wheel body of the first pulling assembly 2, causing failure of operation.

[0043] The pipe pulling device 100 in the embodiment of the utility model can realize effective connection of the pipe rolling process and the cutting process, improve the degree of automation, reduce the labor intensity of workers, and improve the production efficiency.

[0044] The pipe pulling device 100 of some specific embodiments of the utility model is described below.

[0045] Referring to Figures 1 to 7 A pipe pulling device 100 includes a conveying frame 1, a first pulling assembly 2, and a second pulling assembly 3.

[0046] The conveying frame 1 is used to carry the pipe, and the pipe can move on the conveying frame 1, thereby realizing turnover of the pipe after rolling and facilitating subsequent cutting operation.

[0047] The conveying frame 1 includes a support 11 and a support groove 12. The support 11 is telescopic in the vertical direction. For example, the support 11 includes an inner tube and an outer tube arranged coaxially, the inner tube can slide up and down in the outer tube, and a power component such as a pneumatic cylinder, a hydraulic cylinder, or an electric push rod is arranged between the inner tube and the outer tube, so that the height of the support groove 12 can be adjusted as needed. The number of supports 11 is multiple, and the multiple supports 11 are arranged at intervals along the length direction of the support groove 12. The support groove 12 is V-shaped, and when the pipe is placed in the support groove 12, the pipe and the support groove 12 are in line contact, which can reduce the friction coefficient. Of course, a coating with lubricating properties can also be applied to the inner surface of the support groove 12.

[0048] The conveying frame 1 in the embodiment is two, one of which is located on the feeding side of the first pulling assembly 2, that is, the right side of the first pulling assembly 2 shown in Figure 1 The other conveying frame 1 is located between the first pulling assembly 2 and the second pulling assembly 3, that is, the left side of the first pulling assembly 2 and the right side of the second pulling assembly 3 shown in Figure 1 .

[0049] The first pulling assembly 2 is located in the middle of the conveying frame 1 to pull the pipe to move along the conveying frame 1.

[0050] The first material pulling assembly 2 includes a first frame 21, a fixed plate 25, a movable plate 26, a first wheel 22, a second wheel 23, a first driver 24, and a slide rail 28. The fixed plate 25 is fixed to the first frame 21, and the movable plate 26 is movably disposed on the first frame 21. The movable plate 26 moves along a first direction on the first frame 21. Figure 1 and Figure 2 The slide rail 28 (shown in the up-down direction) is movable. The length direction of the slide rail 28 is parallel to the first direction. One end of the slide rail 28 is connected to the fixed plate 25. The movable plate 26 is provided with a sliding element that matches the slide rail 28. For example, a guide sleeve is provided on the movable plate 26, and the slide rail 28 serves as a guide rod; the guide sleeve and guide rod are slidably engaged together. This ensures smooth sliding of the movable plate 26. A third actuator 27 is provided between the fixed plate 25 and the movable plate 26.

[0051] In this embodiment, the first wheel 22 is mounted on the fixed plate 25, and the second wheel 23 is mounted on the movable plate 26. There are multiple first wheels 22 and multiple second wheels 23, with the first wheels 22 spaced apart along the left-right direction on the fixed plate 25, and the multiple second wheels 23 spaced apart along the left-right direction on the movable plate 26. The first wheels 22 and the second wheels 23 are arranged in a one-to-one correspondence. Both the fixed plate 25 and the movable plate 26 are equipped with a first driver 24, and each first wheel 22 and each second wheel 23 is connected to a first driver 24, thus making both the first wheels 22 and the second wheels 23 driving wheels, increasing the pulling force on the pipe.

[0052] This embodiment, through the arrangement of multiple first wheel bodies 22 and second wheel bodies 23, can increase the pulling force on the pipe and reduce the load on a single first driver 24.

[0053] A gap is formed between the first wheel 22 and the second wheel 23, through which the pipe can pass. It is understood that after the pipe on the feeding frame 1 is fed between the first wheel 22 and the second wheel 23, the first wheel 22 and the second wheel 23 move closer together and clamp the pipe. Under the action of the first driver 24, the first wheel 22 and the second wheel 23 rotate and apply a pulling force to the pipe, thus achieving material pulling.

[0054] The second material pulling assembly 3 is located at the discharge end of the conveyor frame 1 to pull the pipe away from the first material pulling assembly 2. It is understood that, as Figure 1 As shown, the rolled tube moves from right to left on the feeder 1, and the first pulling assembly 2 can continuously pull the tube to the left. When a single rolling cycle ends, the second pulling assembly 3 can further convey the tube to the left, causing the tube to detach from the first pulling assembly 2 and move further to the left.

[0055] The second pulling assembly 3 comprises a second frame 31, a third wheel body 32, a fourth wheel body 33, a second driver 34, a fourth driver 35 and a mounting base 36. The third wheel body 32 and the fourth wheel body 33 are arranged oppositely in a second direction (the front-rear direction shown in the figure) and are both connected to the second frame 31. Specifically, the fourth driver 35 is connected to the second frame 31, the mounting base 36 is connected to the output end of the fourth driver 35, the third wheel body 32 is connected to the mounting base 36 through a connecting shaft 37 to drive the third wheel body 32 to move in the second direction by the fourth driver 35, and the second driver 34 is in driving connection with the fourth wheel body 33. Figure 1 and Figure 2 It can be understood that after the pipe material on the feeding frame 1 is fed between the third wheel body 32 and the fourth wheel body 33, the third wheel body 32 and the fourth wheel body 33 are close to each other and clamp the pipe material. Under the action of the second driver 34, the third wheel body 32 and the fourth wheel body 33 rotate and exert a pulling force on the pipe material to realize pulling. In normal cases, the first pulling assembly 2 and the second pulling assembly 3 can simultaneously pull the pipe material. When the rolled pipe material is finished rolling, the tail of the pipe material passes through the gap between the first wheel body 22 and the second wheel body 23, then only the second pulling assembly 3 pulls the pipe material, and the pipe material is separated from the first pulling assembly 2 and moves further to the left.

[0056] The first direction is orthogonal to the feeding direction of the feeding frame, and the second direction is orthogonal to the vertical direction and the feeding direction of the feeding frame. The first pulling assembly is located in the middle of the feeding frame to pull the pipe material to move along the feeding frame, and the second pulling assembly is located downstream of the first pulling assembly to pull the pipe material to separate from the first pulling assembly.

[0057] In the embodiment, the first direction and the second direction are orthogonal, the first direction is parallel to the vertical direction, that is, the first direction is the up-down direction shown in the figure, and the second direction is the front-rear direction shown in the figure. During the pulling process, the first wheel body and the second wheel body can clamp the pipe material in the up-down direction, and the third wheel body and the fourth wheel body can clamp the pipe material in the front-rear direction, thereby ensuring the stable movement of the pipe material in the feeding frame.

[0058] Since the rolled pipe material needs to be cut off, when the pipe material separates from the first pulling assembly 2, it can stably enter the next process, avoiding that the pipe material is partially overlapped on the equipment of the next process and partially located between the first wheel body and the second wheel body of the first pulling assembly 2, resulting in failure to work.

[0059] Since the rolled pipe material needs to be cut off, when the pipe material separates from the first pulling assembly 2, it can stably enter the next process, avoiding that the pipe material is partially overlapped on the equipment of the next process and partially located between the first wheel body and the second wheel body of the first pulling assembly 2, resulting in failure to work.

[0060] In the embodiment, the circumferential wall surface of the first wheel body 22, the second wheel body 23, the third wheel body 32 and the fourth wheel body 33 has an anti-skid layer. For example, a rubber layer is arranged on the surface of the wheel body, so that the clamping effect of the wheel body on the pipe material can be improved, the wheel body and the pipe material are prevented from slipping, and the pulling force is increased. The first driver 24 and the second driver 34 can be driving motors, and the third driver 27 and the fourth driver 35 can be air cylinders, hydraulic cylinders or electric push rods. The first frame body 21 and the second frame body 31 can also be arranged as frame bodies with a lifting function, for adjusting the height of the corresponding wheel body.
