Description

Technical Field

[0001] This invention relates to the field of pipe conveying technology, specifically to a conveying device for pipe processing. Background Technology

[0002] The cold rolling production line for pipe fittings is the core equipment for manufacturing high-precision, high-performance seamless steel pipes. Its core process is cold rolling, which involves rolling hollow blank pipes through an annular die without heating, thereby reducing the wall thickness, diameter, and length, and significantly improving the material properties.

[0003] Currently, in the cold rolling process of pipe fittings production lines, a combination of chucks, feed boxes, body boxes, and rolling boxes is used for clamping and positioning, first conveying, second conveying and rolling preparation, and final rolling, ultimately resulting in thinner, longer, and more precise finished pipes. The chuck typically consists of 2-4 jaws, a hydraulic or servo drive mechanism, a high-precision guide rail, and a position detection system, performing initial positioning and clamping as well as preparing for the first conveying. The feed box pushes the pipe along the production line axis and moves it to a preset position. The conveying box mainly provides stable support for the conveyed pipe along its entire length, ensuring the straightness of the movement and transitioning to subsequent chucks and conveying boxes. Subsequent chucks and conveying boxes perform feeding cycles and cooperate with rolling to provide stable tension during the rolling process.

[0004] However, during the cold rolling process, the part that has entered the deformation zone is in a completely different mechanical and physical state from the tube body that has not yet entered the deformation zone. If the surface of the unrolled part of the tube is not properly treated or is in poor condition, it will seriously affect the final cold rolling quality. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying device for pipe processing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a conveying device for pipe processing, comprising a chuck assembly, a conveying box, and a feeding box arranged sequentially along a straight direction, a cold rolling box arranged on the other side of the feeding box, a set of conveying shafts arranged inside the conveying box, a conveying trolley connected to the surface of the set of conveying shafts, conveying holes on both sides of the conveying box facing the pipe conveying direction, a pipe body detection assembly arranged between the conveying box and the feeding box, the pipe body detection assembly including an auxiliary wheel and a second support ring arranged in parallel, and an auxiliary wheel fixedly installed inside the auxiliary wheel. The detection unit is used to scan and obtain the wall thickness parameters of the pipe. The second support ring is aligned with the transmission hole. A set of pressure sensors is uniformly penetrated and fixedly connected to the outer surface of the second support ring. The signal input end of the pressure sensor is fixedly connected to a pressure sensing unit. Several pressure sensing units form a ring structure around the outer ring of the pipe. The center line of the ring structure formed by the pressure sensing units coincides with the center line of the preset pipe position. The inner wall of the pressure sensing unit and the outer wall of the pipe form a transmission reserved area. The transmission device also includes a data processing end, which is signal-connected to the auxiliary detection unit and the pressure sensing units.

[0007] The present invention further illustrates that a drive wheel and a support wheel are respectively meshed and connected on the lower two sides of the auxiliary wheel. A rotating shaft is connected through the middle of both the drive wheel and the support wheel. A second fixed frame is connected to each end of the rotating shaft by bearings. A second drive motor is fixedly connected to the second fixed frame connected to the drive wheel.

[0008] The present invention further illustrates that the outer wall of the second support ring is fixedly supported by a third fixing frame, and the bottom of the conveying box and the feeding box is fixedly installed with a second base box. The second fixing frame and the third fixing frame are fixedly connected to the second base box through a frame plate.

[0009] The present invention further describes that the chuck assembly includes a chuck box, the bottom of which is supported and connected to a base box. A first drive motor is installed on the side wall surface of the chuck box perpendicular to the pipe conveying direction of the conveyor box. The output end of the first drive motor is fixedly connected to a driving bevel gear through a coupling. A driven bevel gear is driven and connected to one side of the driving bevel gear. A hollow rod is connected through the middle of the driven bevel gear. A set of spur gears is driven and connected to the side of the driven bevel gear away from the pipe feeding direction. The set of spur gears is driven and connected to the conveyor shaft through a shaft.

[0010] The present invention further describes that a clamping assembly is installed on the outer ring of the conveying hole near the side of the feeding box. The clamping assembly includes a first support ring fixedly connected to the outer ring of the conveying hole. A set of first fixing frames is fixedly installed on the outer ring of the first support ring. The first fixing frames are U-shaped. A telescopic part is installed inside the first fixing frame. The output end of the telescopic part passes through the frame of the first fixing frame and is fixedly connected to a slider.

[0011] The present invention further explains that a corresponding groove is provided at the position of the first support ring matching the slider, and a slide rail that is slidably connected to the inner wall of the groove is fixedly connected to the inner wall of the groove. A clamping part is fixedly connected to the side surface of the slider facing the center line of the conveying hole, and the clamping part is used to assist in contact with the surface of the pipe.

[0012] The present invention further illustrates that an anti-slip layer is fixedly connected to the surface of the clamping part facing the tube.

[0013] The present invention further explains that the tube detection component is used to detect the surface data of the tube in the cold rolling process. The surface data includes wall thickness parameters and pressure parameters. In the cold rolling process of the tube, the pressure sensing unit can perform vibration detection of the tube during the cold rolling process.

[0014] The present invention further explains that the positions and numbers of the clamping part and the pressure sensing part are consistent. When the outer wall of the pipe exceeds the conveying reserved area, the clamping part at the corresponding position is locked according to the position of the pressure sensing part with the measured pressure parameters. According to the locked position of the clamping part, the clamping part at that position pushes the surface of the pipe at the corresponding position under the action of the telescopic part until the outer wall of the pipe is within the conveying reserved area, and the telescopic part stops extending.

[0015] The present invention further explains that when the pipe is located within the reserved area for conveying, the auxiliary detection unit will perform wall thickness detection of the pipe under the action of the drive wheel, thereby obtaining the wall thickness parameters of the pipe section, forming a wall thickness parameter set, and using the variance calculation method to calculate the data dispersion of the wall thickness parameter set.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention uses a tube body detection component to detect the surface data of the tube during the cold rolling process, wherein the surface data includes wall thickness parameters and pressure parameters, thereby enabling effective adjustment of the process to improve the cold rolling quality of the tube.

[0028] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 9 The present invention provides a technical solution: a conveying device for pipe processing, used to assist in the cold rolling process of tube materials for continuous intelligent feeding. The conveying device includes a chuck assembly 4, a conveying box 1, and a feeding box 7 arranged sequentially in a straight line. The chuck assembly 4 is used to provide a clamping and rotating function for hollow rods. A cold rolling box is provided on the other side of the feeding box 7, which is not shown in the figure. A set of conveying shafts 2 are provided inside the conveying box 1. The surface of the set of conveying shafts 2 is provided with threads in the same direction of rotation, and a conveying trolley 3 is connected to it through a ball nut drive. The conveying trolley 3 on the conveying box 1 uses the chuck assembly 4 and the feeding box 7 to hug the tube material toward the cold rolling box. The rolling box is used to receive the hugged tube material and cold roll it.

[0030] Furthermore, the chuck assembly 4 includes a chuck box 41, with a base box 1 supported at the bottom of the chuck box 41. A first drive motor 42 is mounted on the side wall of the chuck box 41 perpendicular to the pipe conveying direction of the conveyor box 1. The output end of the first drive motor 42 is fixedly connected to a driving bevel gear 43 via a coupling. A driven bevel gear 44 is drivenly connected to one side of the driving bevel gear 43. A hollow rod is connected through the middle of the driven bevel gear 44. The hollow rod is used to place and convey the pipe. A set of spur gears 45 is drivenly connected to the side of the driven bevel gear 44 away from the pipe feeding direction. The set of spur gears 45 includes at least a first spur gear, a second spur gear, and a third spur gear. The first spur gear is fixedly connected to the driven bevel gear 44. The second spur gear and the third spur gear are respectively meshed and connected to the lower two sides of the first spur gear. The middle parts of the second spur gear and the third spur gear are respectively drivenly connected to the conveyor shaft 2 via shafts.

[0031] When the first drive motor 42 starts in the forward direction, the active bevel gear 43 will drive the driven bevel gear 44 to rotate. When the driven bevel gear 44 rotates, it drives the spur gear set 45 to rotate, which in turn drives the transmission shaft 2 to rotate. That is, through the use of the first drive motor 42, the rotation within the chuck assembly 4 and the transmission of the pipe by the transmission trolley 3 are realized. In addition, a hydraulic telescopic rod is installed on the top of the chuck box 41. The output end of the hydraulic telescopic rod is connected to the chuck through the rod transmission. The telescopic process is used to control the clamping and loosening of the chuck. This is existing technology and will not be described in detail here.

[0032] In addition, the conveyor trolley 3 can refer to the structural design of the chuck assembly 4. In addition to the conveyor pipe that is connected through the bearing inside, the conveyor pipe is used to place the pipe material transmitted by the chuck assembly 4. A hydraulic telescopic rod is installed on the top of the conveyor trolley 3. A chuck is supported and connected to the surface of the conveyor trolley 3 facing the feeding box 7 by a rod. The middle part of the chuck is used to pass through and clamp the pipe material. The output end of the chuck is connected to the output end of the hydraulic telescopic rod by a rod. Similarly, the output end of the hydraulic telescopic rod is connected to the chuck by a rod to control the clamping and loosening of the chuck. This will not be described in detail here.

[0033] In the above structural configuration, after the previous top-feeding process, the pipe enters the chuck assembly 4. The previous top-feeding process can be performed by the top-feeding structure or manually. After the pipe enters the chuck assembly 4, the conveying trolley 3 is initially positioned adjacent to the chuck assembly 4. When the pipe is topped into the chuck assembly 4, one end of the pipe will also pass through the conveying pipe inside the conveying trolley 3 and the external chuck 1, with the chuck 1 remaining in a detached state. If the chuck is in a clamped state, the pipe conveying is paused. If the pipe needs to be conveyed in the conveying box 1, the chuck is adjusted to a detached state, and the chuck 1 is adjusted to a clamped state. The first drive motor 42 starts in the forward direction, and the conveying trolley 3 clamps the pipe and conveys it towards the feeding box 7 and the cold rolling box. After the pipe conveying and cold rolling are completed, the first drive motor 42 starts in the reverse direction, and the conveying trolley 3 is reset to its initial position to prepare for the clamping and conveying of the next pipe.

[0034] Furthermore, the conveying box 1 has conveying holes on both sides facing the pipe conveying direction. A clamping assembly 5 is installed on the outer ring of the conveying hole near the feeding box 7 to assist in clamping the pipe. Specifically, the clamping assembly 5 includes a first support ring 51 fixedly connected to the outer ring of the conveying hole. A set of first fixing frames 52 is fixedly installed on the outer ring of the first support ring 51. The first fixing frames 52 are U-shaped. A telescopic part 53 is installed inside the first fixing frame 52. The output end of the telescopic part 53 passes through the frame of the first fixing frame 52 and is fixedly connected to a slider 55. A corresponding groove 54 is provided on the first support ring 51 at the position matching the slider 55. A slide rail is fixedly connected to the inner wall of the groove 54 and slides slidably connected to the slider 55 to limit and stabilize the sliding direction of the slider 55. A clamping part 56 is fixedly connected to the side of the slider 55 facing the center line of the conveying hole. The clamping part 56 is used to assist in contact with the surface of the pipe. Figure 5 As shown, the clamping part 56 can be a ring structure that matches the surface of the pipe or a rod structure. The figure uses a ring structure as an example, and the specific shape of the clamping part 56 is not limited. An anti-slip layer is also fixedly connected to the surface of the clamping part 56 facing the pipe.

[0035] When the pipe has undergone a section of surface cold rolling, the conveying trolley 3 pauses conveying and the chuck remains clamped. When the pipe undergoes the next section of surface cold rolling, the conveying trolley 3 continues to convey a section of surface cold rolling and the chuck remains clamped. Then the above process is repeated to perform the surface cold rolling process of that section of pipe. During the cold rolling process, the cold rolling box will repeatedly perform surface cold rolling of the pipe. If it is necessary to improve the stability of the pipe during the cold rolling process, the clamping process of the clamping assembly 5 can be used to improve the cold rolling stability of the pipe.

[0036] Furthermore, a tube detection component 6 is provided between the conveyor box 1 and the feed box 7. The tube detection component 6 is used to detect the surface data of the tube during the cold rolling process. The surface data includes wall thickness parameters and pressure parameters, which can effectively adjust the process to improve the cold rolling quality of the tube. Specifically, a bottom box 2 is fixedly installed at the bottom of the conveyor box 1 and the feed box 7 to support the conveyor box 1 and the feed box 7 and to keep the tube conveyed in a straight line.

[0037] The pipe inspection assembly 6 includes an auxiliary wheel 61 and a second support ring 65 arranged side by side. A drive wheel 62 and a support wheel 63 are respectively meshed on the lower sides of the auxiliary wheel 61. A rotating shaft is connected through the middle of the drive wheel 62 and the support wheel 63. A second fixed frame 64 is connected to each end of the rotating shaft by bearings. The second fixed frame 64 is fixedly connected to the bottom box 2 by a frame plate. A second drive motor is fixedly connected to the second fixed frame 64 connected to the drive wheel 62. An auxiliary inspection unit 67 is fixedly installed inside the auxiliary wheel 61. The auxiliary inspection unit 67 is preferably an infrared scanner, which is used to scan and obtain the wall thickness parameters of the pipe.

[0038] The second support ring 65 is aligned with the conveying hole. A set of pressure sensing units 68 are uniformly penetrated and fixedly connected to the outer surface of the second support ring 65. The signal input end of the pressure sensing unit 68 is fixedly connected to a pressure sensing unit 66. Several pressure sensing units 66 form a ring structure surrounding the outer ring of the pipe. The outer wall of the second support ring 65 is fixedly supported by a third fixing frame 69, which is also fixedly connected to the bottom box 2 via a frame plate. The center line of the ring structure formed by the pressure sensing units 66 coincides with the center line of the preset pipe position. Thus, a conveying reserved area is formed between the inner wall of the pressure sensing unit 66 and the outer wall of the pipe. When the pipe is continuously conveyed within the conveying reserved area, such as Figure 7 As shown, the surface of the pipe will not contact the inner wall of the pressure sensing part 66, and the pressure sensing part 68 will not receive a pressure signal. When the surface of the pipe contacts the inner wall of the pressure sensing part 66 and pressure occurs, the pressure sensing part 68 will receive a pressure signal, which will be converted into pressure parameters for transmission.

[0039] The conveying device also includes a data processing end, which is signal connected to the drive motor, the pump connected to the hydraulic telescopic rod, the pump connected to the telescopic part 53, the auxiliary detection part 67, and the pressure sensing part 68. On the one hand, it is used to receive the measured surface data, and on the other hand, it performs remedial measures or alarm measures based on the surface data to improve the cold rolling quality of the pipe.

[0040] In this embodiment, when the pipe is conveyed through the pipe detection component 6, the pressure sensor 68 monitors the pressure to ensure that the outer wall of the pipe does not exceed the conveying reserved area. When the outer wall of the pipe exceeds the conveying reserved area, the clamping part 56 at the corresponding position is locked according to the position of the pressure sensor 68 based on the measured pressure parameters. It should be noted that in this embodiment, the position and number of clamping parts 56 are consistent with those of the pressure sensor 68. Next, according to the locked position of the clamping part 56, the clamping part 56 at that position pushes the surface of the pipe at the corresponding position under the action of the telescopic part 53 until the outer wall of the pipe is within the conveying reserved area, at which point the telescopic part 53 stops extending.

[0041] like Figure 8 As shown, when the pipe is pressed against the two pressure-sensing parts 66, the telescopic parts 53 at the corresponding two positions are activated and push the clamping parts 56 until the outer wall of the pipe is within the conveying reserved area, and so on.

[0042] like Figure 9 As shown, when the outer wall of the pipe is located within the conveying reserved area but the external protrusion presses against the pressure sensing part 66, it indicates that the presence of the protrusion will affect the cold rolling effect of the pipe at that location. When this situation occurs, the data processing terminal will issue an alarm, the cold rolling process will be suspended, and the staff will be notified to inspect the pipe. If the situation is true, the cold rolling process of the pipe will be suspended.

[0043] When ensuring that the pipe is within the reserved conveying area, the auxiliary detection unit 67 will perform wall thickness detection on the pipe under the action of the drive wheel 62, thereby obtaining the wall thickness parameters of the pipe section and forming a wall thickness parameter set. Using the variance calculation method, the dispersion of the data in the wall thickness parameter set is calculated. When the dispersion is high, it indicates that the wall thickness is seriously uneven, which is not conducive to the quality of the pipe after cold rolling, and the cold rolling process needs to be suspended. When the dispersion is low, the cold rolling process of the pipe can continue.

[0044] In addition, during the cold rolling process of the pipe, when the pressure sensing unit 68 completes the detection of whether the outer wall of the pipe is located within the conveying reserved area, it can also perform vibration detection of the pipe during the cold rolling process. The vibration threshold Q of each pressure sensing unit 68 is set in advance in the data processing terminal, and the actual pressure detected by the pressure sensing unit 68 is qi, i is 1 to n, n is the total number of pressure sensing units 68, and i is the serial number of the pressure sensing unit 68.

[0045] When the pressure sensor 68 does not detect qi≥Q, it indicates that the vibration is normal and there is no need to adjust the process in the cold rolling process.

[0046] When the pressure sensor 68 detects that qi≥Q when the pressure is less than n / 2, it indicates that the vibration is slight. The clamping assembly 5 will further clamp the surface of the tube to improve the cold rolling quality of the front tube.

[0047] When the pressure sensor 68 detects qi≥Q at a pressure not less than n / 2, it indicates that the vibration is severe. The cold rolling parameters will be adjusted manually at the cold rolling box, such as slowing down the cold rolling speed, to ensure the cold rolling quality of the outer wall of the pipe.

[0048] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features, and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
