Description

Technical Field

[0001] This invention relates to the technical field of pipe production, and more specifically, to a pipe traction machine. Background Technology

[0002] During the pipe production process, a pipe traction machine is needed to pull the pipe. During the traction process, a certain clamping force is applied to the pipe. However, the freshly extruded pipe is prone to deformation or collapse due to excessive clamping force, resulting in a high defect rate. On the other hand, the existing pipe traction machine is prone to skewed stretching due to initial stretching position deviation, which in turn leads to pipe bending and damage.

[0003] Existing technology discloses a pipe traction machine, including a base, a guide rod on the base, and a mounting frame on the guide rod. A connecting sleeve is sleeved on the guide rod, and the mounting frame is fixed to the connecting sleeve. There are two sets of mounting frames and two sets of connecting sleeves, respectively located at the upper and lower parts of the guide rod. A conveyor belt is provided inside the mounting frame, and a first cavity is provided inside the conveyor belt. A first connecting plate is provided on the conveyor belt, and a second cavity communicating with the first cavity is provided inside the first connecting plate. An airbag is provided on the first connecting plate, and a first through hole communicating with the airbag is provided on the side wall of the second cavity. An air pump communicating with the first cavity is provided at the top of the mounting frame. By having the airbag contact the pipe, the airbag wraps around the side wall of the pipe, achieving curved surface contact between the conveyor belt and the pipe, increasing the contact area between the conveyor belt and the pipe, and providing reliable power for the conveying of the pipe. However, in this solution, the pipe is driven and clamped by the airbag at the same time, resulting in a large clamping force on the pipe, which can easily lead to pipe deformation or collapse, and a high scrap rate. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pipe traction machine that prevents pipes from deforming or collapsing due to excessive clamping force, ensures traction quality, and improves the yield of pipe products.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A pipe traction machine is provided, comprising two sets of traction mechanisms. Each traction mechanism includes a frame, a first drive motor, a drive wheel, a driven wheel, and a transmission belt. The transmission belt is wound between the drive wheel and the driven wheel. The drive wheel and the driven wheel are rotatably mounted on the frame. The output shaft of the first drive motor is connected to the drive wheel. The machine also includes drive blocks, adsorption seats, and an air supply pipe for an external air pump. A plurality of drive blocks and air supply pipes are disposed on the outer surface of the transmission belt. A plurality of adsorption seats are evenly spaced and are respectively connected to the air supply pipes.

[0007] The pipe traction machine of this invention uses two first drive motors to drive two transmission belts, which in turn move drive blocks. The drive blocks on the two sets of traction mechanisms cooperate to clamp the pipe, achieving pipe stretching. Simultaneously, an air pump evacuates the air supply pipeline, causing the adsorption seat to adsorb the pipe, which assists in clamping the pipe and prevents the pipe from shifting or misaligning during stretching. This invention can prevent the pipe from deforming or collapsing due to excessive clamping force during stretching, ensuring stretching quality and improving the pipe yield.

[0008] Furthermore, several driving blocks are respectively disposed between two adjacent adsorption seats. The driving blocks are used to clamp the driving tube, and the adsorption seats adsorb the tube to assist in the tube stretching. Multiple sets of adsorption seats can ensure the stability of adsorption. The driving blocks and adsorption seats are arranged in a cross manner to avoid interference between the driving blocks and adsorption seats, and at the same time to avoid excessive local clamping force on the tube.

[0009] Furthermore, one side of the drive block is fixedly connected to the transmission belt, and the other side of the drive block is detachably connected to an anti-slip pad. The anti-slip pad can, to a certain extent, restrict the pipe material, effectively solving the problem of accidental detachment of the pipe material during the drawing process, thereby facilitating the normal operation of the drawing process. When the anti-slip pad becomes severely worn due to prolonged use, resulting in low limiting effect and inability to support and limit the pipe material, the unusable anti-slip pad can be removed and a new anti-slip pad can be installed on the drive block.

[0010] Furthermore, the gas transmission pipeline is located in the middle of the transmission belt, and the drive blocks are located on both sides of the gas transmission pipeline.

[0011] Furthermore, the thickness of the drive block gradually increases from the end closest to the gas pipeline to the end furthest from the gas pipeline. This increases the contact area between the drive block and the pipe, which can, to some extent, restrict the drawn pipe, prevent the pipe from shifting position, and also prevent the pipe from slipping off.

[0012] Furthermore, the adsorption seat is connected to the gas supply pipeline via a branch pipe, and the branch pipe is equipped with a valve. By controlling the opening and closing of the valve, the adsorption seat can be controlled to adsorb or detach the pipe. When the pipe enters between the two transmission belts, the valve is in the open state. Under the suction action of the air pump, the adsorption seat adsorbs and limits the pipe from the upper and lower sides. Driven by the first drive motor, the driving wheel drives the driven wheel to rotate through the transmission belt. At the same time, the transmission belt moves the pipe from one end of the frame to the other end of the frame. After a certain period of traction, the valve is closed, so that the adsorption seat stops adsorbing the pipe, thereby facilitating the unloading of the pipe.

[0013] Furthermore, it also includes a plurality of support rollers, which are disposed between the driving wheel and the driven wheel, and are rotatably mounted on the frame. When the first drive motor drives the transmission belt, the plurality of support rollers assist in supporting and tensioning the transmission belt to prevent deformation of the transmission belt from causing unstable clamping of the pipe.

[0014] Furthermore, it also includes a fixed frame and an adjusting frame, the adjusting frame being slidably connected to the fixed frame, and the two sets of frames being connected to the fixed frame and the adjusting frame respectively. Specifically, the top of the fixed frame has an equipment slot, and a hydraulic cylinder is installed in the equipment slot. The bottom of the hydraulic cylinder is connected to the top of the adjusting frame. In practice, the adjusting frame is driven to rise and fall by the hydraulic cylinder, thereby adjusting the distance between the two sets of traction mechanisms to accommodate the drawing of pipes of different sizes.

[0015] Furthermore, the fixed frame is equipped with a control box, a timer, and several monitoring probes. The timer, monitoring probes, and valves are electrically connected to the control box. The monitoring probes are used to check the condition of the pipe before and after stretching. The control box controls the opening and closing of the valves, thereby improving the automation and intelligence level of the traction process.

[0016] Furthermore, it also includes a pretreatment seat located at one end of the frame, the pretreatment seat being provided with an adjustment component for adjusting the position of the pipe.

[0017] Furthermore, the adjustment assembly includes a second drive motor, a lead screw, a first guide plate, and a second guide plate. Both ends of the lead screw are rotatably connected to the pretreatment seat. The two ends of the lead screw are provided with a first screw and a second screw with opposite thread directions. The first guide plate is connected to the first screw, and the second guide plate is connected to the second screw. The second drive motor is connected to one end of the lead screw. The second drive motor drives the lead screw to rotate, thereby causing the first and second guide plates to move closer to or further apart from each other, adjusting the distance between the first and second guide plates. This allows for the compression adjustment of the position of the pipe entering the inner side of the transmission belt, preventing the pipe from becoming misaligned due to initial drafting position deviation and avoiding bending damage to the pipe as a result.

[0018] Furthermore, protective pads are provided on the opposite sides of the first guide plate and the second guide plate to prevent wear on the pipe when adjusting its position.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This invention can prevent the pipe from deforming or collapsing due to excessive clamping force during the stretching process, ensuring stretching quality and improving the yield of pipe products; the pipe position can be adjusted by adjusting the component, which can prevent the pipe from stretching skew due to the initial stretching position deviation, and avoid the pipe bending and damage caused by this.

[0032] Example 1

[0033] A pipe traction machine, such as Figures 1 to 4 and Figure 7 As shown, it includes two sets of traction mechanisms 2. Each set of traction mechanisms 2 includes a frame 21, a first drive motor 22, a drive wheel 23, a driven wheel 24, and a transmission belt 25. The transmission belt 25 is wound between the drive wheel 23 and the driven wheel 24. The drive wheel 23 and the driven wheel 24 are rotatably mounted on the frame 21. The output shaft of the first drive motor 22 is connected to the drive wheel 23. It also includes drive blocks 4, adsorption seats 3, and an air supply pipe 6 for an external air pump 26. Several drive blocks 4 and air supply pipes 6 are arranged on the outer surface of the transmission belt 25. Several adsorption seats 3 are evenly spaced and are connected to the air supply pipes 6.

[0034] The aforementioned pipe traction machine uses two first drive motors 22 to drive two transmission belts 25, which in turn move the drive blocks 4. The drive blocks 4 on the two sets of traction mechanisms 2 cooperate to clamp the pipe, achieving pipe stretching. Simultaneously, an air pump 26 evacuates air from the air supply pipe 6, causing the adsorption seat 3 to adsorb the pipe, which assists in clamping the pipe and prevents the pipe from shifting or misaligning during the stretching process. This invention can prevent the pipe from deforming or collapsing due to excessive clamping force during the stretching process, ensuring stretching quality and improving the pipe yield.

[0035] Among them, the gas transmission pipeline 6 is connected to the air pump 26 via the telescopic pipe 27, such as Figure 2 As shown, this ensures that the suction seat 3 can properly adsorb the pipe during the movement of the transmission belt 25.

[0036] like Figure 1 , Figure 2 and Figure 7 As shown, several driving blocks 4 are respectively arranged between two adjacent adsorption seats 3. The driving blocks 4 are used to clamp the driving tube. The adsorption seats 3 adsorb the tube and assist in the tube stretching. Multiple sets of adsorption seats 3 can ensure the stability of adsorption. The driving blocks 4 and adsorption seats 3 are arranged in a cross manner to avoid interference between the driving blocks 4 and adsorption seats 3, and at the same time to avoid excessive local clamping force on the tube.

[0037] like Figure 3 , Figure 4 and Figure 7 As shown, the gas transmission pipe 6 is located in the middle of the transmission belt 25, and the drive block 4 is located on both sides of the gas transmission pipe 6. Specifically, the thickness of the drive block 4 gradually increases from the end closer to the gas transmission pipe 6 to the end farther away from the gas transmission pipe 6, which can increase the contact area between the drive block 4 and the pipe, and can restrict the drawn pipe to a certain extent, prevent the pipe from shifting position, and also prevent the pipe from slipping.

[0038] The adsorption seat 3 is connected to the gas supply pipeline 6 via a branch pipe, and the branch pipe is equipped with a valve 28, such as... Figure 4 As shown. Specifically, the adsorption seat 3 can be controlled to adsorb or detach the pipe by controlling the opening and closing of the valve 28. When the pipe enters between the two transmission belts 25, the valve 28 is in the open state. Under the suction action of the air pump 26, the adsorption seat 3 adsorbs and limits the pipe from the upper and lower sides. Driven by the first drive motor 22, the drive wheel 23 drives the driven wheel 24 to rotate through the transmission belt 25. At the same time, the transmission belt 25 drives the pipe to move from one end of the frame 21 to the other end of the frame 21. After a certain period of traction, the valve 28 is closed, so that the adsorption seat 3 stops adsorbing the pipe, which facilitates the unloading of the pipe and prevents its position from shifting or misaligning during the stretching process.

[0039] like Figure 1 , Figure 2 As shown, it also includes several support rollers 29, which are disposed between the driving wheel 23 and the driven wheel 24, and are rotatably mounted on the frame 21. Specifically, when the first drive motor 22 drives the transmission belt 25, the several support rollers 29 assist in supporting and tensioning the transmission belt to prevent deformation of the transmission belt 25 from causing unstable clamping of the pipe.

[0040] Example 2

[0041] This embodiment is similar to Embodiment 1, except that one side of the drive block 4 is fixedly connected to the transmission belt 25, and the other side of the drive block 4 is detachably connected to an anti-slip pad 5, such as... Figure 1 , Figure 2 and Figure 4As shown. The anti-slip pad 5 can, to a certain extent, restrict the pipe material, effectively solving the problem of accidental detachment of the pipe material during the drawing process, thereby facilitating the normal progress of the drawing work. Specifically, as... Figure 5 As shown, the top of the drive block 4 is provided with several spaced protrusions 41, and the bottom of the anti-slip pad 5 is provided with several slots 51, and the protrusions 41 and the slots 51 are engaged one by one. When the anti-slip pad 5 is severely worn due to long-term use, resulting in low limiting effect and inability to support and limit the pipe, the unusable anti-slip pad 5 can be pulled out, so that the slots 51 are disengaged from the protrusions 41 on the drive block 4, and a new anti-slip pad 5 can be installed on the drive block 4.

[0042] Example 3

[0043] This embodiment is similar to Embodiment 1 or Embodiment 2, except that, as Figure 1 , Figure 2 and Figure 7 As shown, it also includes a fixed frame 11 and an adjusting frame 14. The adjusting frame 14 is slidably connected to the fixed frame 11, and the two sets of frames 21 are respectively connected to the fixed frame 11 and the adjusting frame 14. Specifically, the fixed frame 11 is provided with a top seat 12, and the top seat 12 has an equipment slot 121. A hydraulic cylinder 13 is provided in the equipment slot 121. The bottom of the hydraulic cylinder 13 is connected to the top of the adjusting frame 14. In practice, the adjusting frame 14 is driven to rise and fall by the hydraulic cylinder 13, thereby adjusting the distance between the two sets of traction mechanisms 2 to accommodate the drawing of pipes of different sizes.

[0044] like Figure 1 , Figure 2 As shown, the mounting bracket 11 is equipped with a control box 111, a timer 112, and several monitoring probes 113. The timer 112, monitoring probes 113, and valve 28 are electrically connected to the control box 111, as shown. Figure 6 As shown, several monitoring probes 113 are used to check the condition of the pipe before and after drawing. The valve 28 can be opened and closed at regular intervals by timer 112, which facilitates the normal feeding of the pipe and improves the automation and intelligence level of the drawing process.

[0045] Example 4

[0046] This embodiment is similar to Embodiment 1, except that, as Figure 1 , Figure 2 and Figure 7 As shown, it also includes a pretreatment seat 15 located at one end of the frame 21. The pretreatment seat 15 is provided with a treatment cavity, and an adjustment component 7 for adjusting the position of the pipe is provided in the treatment cavity.

[0047] like Figures 1 to 3 and Figure 7As shown, the adjustment assembly 7 includes a second drive motor 71, a lead screw 72, a first guide plate 73, and a second guide plate 74. The two ends of the lead screw 72 are rotatably connected to the pretreatment seat 15, respectively. The first guide plate 73 and the second guide plate 74 are located in the treatment cavity. The two ends of the lead screw 72 are provided with a first screw and a second screw with opposite thread directions. The first guide plate 73 is connected to the first screw, and the second guide plate 74 is connected to the second screw. The second drive motor 71 is connected to one end of the lead screw 72. Specifically, it also includes several traction rods 76 and several sliding sleeves. The two ends of the traction rods 76 are fixed to the pretreatment seat 15, and the traction rods 76 slide through the sliding sleeves. The sliding sleeves are respectively connected to the first guide plate 73 and the second guide plate 74. In practice, the second drive motor 71 drives the lead screw 72 to rotate. The sliding cooperation between the sliding sleeves and the traction rods 76 guides the first guide plate 73 and the second guide plate 74, thereby driving the first guide plate 73 and the second guide plate 74 to move towards each other or away from each other, so as to adjust the distance between the first guide plate 73 and the second guide plate 74. This allows for the squeezing and adjustment of the position of the pipe entering the inner side of the transmission belt 25, which helps to prevent the pipe from being skewed due to the initial stretching position deviation and avoids the pipe bending and damage caused by this.

[0048] like Figure 1 , Figure 7 As shown, protective pads 75 are provided on the opposite sides of the first guide plate 73 and the second guide plate 74 to prevent wear on the pipe when adjusting its position.

[0049] like Figure 1 To the diagram and Figure 8 As shown, the pretreatment seat 15 is provided with a maintenance plate 151 on the top, and the first guide plate 73 and the second guide plate 74 are provided with grooves on the top for accommodating the ball 8. The ball 8 is rolled in connection with the maintenance plate 151 to reduce wear during the movement of the first guide plate 73 and the second guide plate 74.

[0050] Specifically, such as Figures 1 to 3 and Figure 7 As shown, it also includes a base 1, a fixing frame 11 and a pretreatment seat 15 disposed on the base 1. There are two sets of fixing frames 11, which are respectively connected to both ends of the frame 21. Monitoring probes 113 are installed on the two sets of fixing frames 11, and the two monitoring probes 113 are respectively located close to both ends of the frame 21. The two monitoring probes 113 check the condition of the pipe before and after drawing.

[0051] like Figure 3 , Figure 4 and Figure 7 As shown, it also includes a device bracket 16 located on top of the base 1, a second drive motor 71 mounted on the device bracket 16, and a first drive motor 22 slidably mounted on the device bracket 16.

[0052] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
