Description

Technical Field

[0001] This invention relates to the technical field of pipe conveying equipment, and in particular to an automatic pipe straightening device. Background Technology

[0002] Pipe conveying devices are one of the core equipment in pipe processing and production. Their application greatly improves the production efficiency of pipe processing. Automated and continuous conveying methods reduce manual intervention and shorten the production cycle. At the same time, precise conveying and positioning functions ensure the high quality of the finished products. From the perspective of industrial upgrading, the technological progress and upgrading of steel pipe conveying devices are of great significance to promoting the overall development of the pipe processing industry. With continuous technological innovation and market expansion, the performance and functions of these devices have been further improved and perfected, providing more efficient and intelligent solutions for the pipe processing industry.

[0003] A pipe conveying device with anti-deviation function, Chinese patent application number CN202411789615.7, includes a pipe hopper, a transport correction component, a pipe clamping component, a support, a feeding gripper, a feeding device, and a loading component. The invention converts the deformation of the pipe into the displacement of a first transmission rod through a concave measuring wheel. The first transmission rod converts the displacement into a squeezing force on a first piezoelectric element through a first contact. The first piezoelectric element converts the squeezing force into a recognizable electrical signal.

[0004] A fully automatic self-cleaning progressive conveying device for pipes, Chinese patent application number CN202210485874.5, includes a working box, a conveying mechanism at the top and inside of the working box, an outer wall cleaning mechanism on one side of the working box, an adjusting mechanism on the side of the outer wall cleaning mechanism away from the working box, and a pipe body at the top of both the adjusting mechanism and the outer wall cleaning mechanism. The conveying mechanism is used to transport the pipe body.

[0005] Before being placed into the pipe storage area, the pipes often need to be cut. After cutting, the pipes are cleaned of surface oil, scale, and moisture to ensure the effectiveness of subsequent induction heat treatment. However, dust or other impurities inevitably float in the heat treatment workshop, making the pipe surface susceptible to contamination during storage. Furthermore, when drying the moisture on the pipes, the inner center often experiences poor drying, leading to moisture residue. Additionally, the neatness of the pipe stacking is affected during rolling, impacting the accuracy of subsequent feeding and ultimately the effectiveness of induction heat treatment. For example, pipes may enter the heat treatment process prematurely without induction heating being activated, or induction heating may be activated but the pipes are not fed into the heat treatment process. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides an automatic pipe material handling device.

[0016] When the material preparation unit approaches the pipe, the airflow inside the material preparation tube can precisely dry the inside of the pipe to be lifted and blow out impurities. When the mating tube is close to the pipe, the material preparation tube, with the assistance of the first and second protrusions, can make the mating tube rotate intermittently, thereby causing the pipe to rotate intermittently and vibrate, causing the pipe to rub against the adjacent pipe, thus cleaning the external attachments of the pipe.

[0021] 2. By setting up components such as lifting units, material-forming pipes, inner fan blades, and outer fan blades, when the material-forming unit is not close to the pipe, the rotation of the material-forming pipe, with the assistance of the inner and outer fan blades, generates airflow, allowing the hot air from the heat treatment process area to be blown towards the pipe placement area, thereby achieving overall auxiliary drying and dust removal of the pipe.

[0022] 3.

Detailed Implementation

[0025] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0026] like Figures 1 to 4As shown, the present invention provides an automatic pipe material handling device, including a pipe placement rack 1 and pipes 4. The pipe placement rack 1 is provided with a feeding unit 2 and a lifting unit 3. A mesh plate 6 is provided on the side of the pipe placement rack 1. The pipes 4 are placed on the pipe placement rack 1. The mesh plates 6 on both sides are used to limit the position of the pipes 4, so that the pipes 4 are stored in an orderly manner. Then, with the assistance of the lifting unit 3, the pipes 4 can enter the feeding unit 2. Then, with the assistance of the feeding unit 2, the pipes 4 are transported to the heat treatment position. Each lifting of the lifting unit 3 can only feed one pipe 4 into the feeding unit 2.

[0027] The area where pipes 4 are stored on the pipe placement rack 1 is tilted. A diversion plate 7 is provided on the upper end of the pipes 4 on the pipe placement rack 1. Ball bearings are provided on the placement area of ​​the pipe placement rack 1. After the lifting unit 3 sends one pipe 4 to the feeding unit 2, the remaining pipes 4 will move to the upper end of the lifting unit 3 again because the area where the pipes 4 are stored on the pipe placement rack 1 is tilted, in preparation for the next lifting of the pipes 4. During the movement of the pipes 4 in the placement area, with the assistance of the diversion plate 7, the stacked pipes 4 are transformed into a single layer of pipes 4, ensuring the stability of subsequent lifting.

[0028] The lifting unit 3 includes a sliding plate 301, a slider 302 slidably mounted on the side of the sliding plate 301, a handle 303 for driving the slider 302 to move on the side of the sliding plate 301, a vertical hydraulic cylinder 304 on the side of the slider 302, and a lifting plate 305 at the output end of the vertical hydraulic cylinder 304. The upper end of the lifting plate 305 is inclined. In the initial stage of equipment installation, with the assistance of the handle 303, the position of the slider 302 is adjusted according to the diameter of the pipe 4, so that the lifting plate 305 is positioned closest to the pipe 4. Directly below the pipe 4 in the feeding unit 2, when the equipment is conveying the pipe 4, if the pipe 4 at the top of the lifting plate 305 needs to be lifted and conveyed, the vertical hydraulic cylinder 304 is activated. The output end of the vertical hydraulic cylinder 304 drives the lifting plate 305 to rise. When the lifting plate 305 rises, it will lift the pipe 4 upward. After the pipe 4 is lifted to the specified height, due to the structure of the placement area and the influence of the weight of the pipe 4, the pipe 4 will roll in the direction of the feeding unit 2, thereby completing the lifting and conveying of the pipe 4.

[0029] The feeding unit 2 includes a mounting plate 201, a driver 202 mounted on the mounting plate 201, a screw 203 mounted on the driver 202, and a mating rod 204 mounted on the driver 202. The mating rod 204 is threadedly engaged with the screw 203. A handle 205 is provided on the side end of the mating rod 204. A feeding wheel 206 is provided on the top of the screw 203, and a feeding motor is provided on the side end of the feeding wheel 206. In the initial stage of equipment installation, the height of the feeding wheel 206 is adjusted according to the diameter of the pipe 4. Adjustment is performed by rotating the mating rod 204 via the handle 205. When the mating rod 204 rotates, the feeding wheel 206 is raised or lowered by the drive 202 and the screw 203 to adjust the height of the feeding wheel 206. When the pipe 4 is fed to the upper end of the feeding wheel 206 by the lifting unit 3, the feeding wheel 206 is rotated with the assistance of the feeding motor. During the rotation of the feeding wheel 206, the pipe 4 is conveyed to the heat treatment process with the assistance of friction.

[0030] The mating rods 204 in multiple feeding units 2 are connected by couplings. The lifting and lowering of the feeding wheels 206 in multiple feeding units 2 is controlled by handle 205. The middle position of the feeding wheel 206 is recessed. Since there are multiple feeding units 2, the mating rods 204 in multiple feeding units 2 are connected by couplings, so that handle 205 can control all the mating rods 204 at one time. This allows the height of the feeding wheels 206 in multiple feeding units 2 to be adjusted in a coordinated manner. When the middle position of the feeding wheel 206 is recessed, it is beneficial to ensure the stable placement and conveying of the pipe 4 on the feeding wheel 206.

[0031] In the process of using this invention, when the pipe 4 is placed in the placement area on the pipe placement rack 1, the position of the lifting unit 3 and the height of the feeding unit 2 need to be adjusted according to the diameter of the pipe 4. When adjusting the position of the lifting unit 3, the position of the slider 302 is adjusted according to the diameter of the pipe 4 with the assistance of the handle 303, so that the lifting plate 305 is located directly below the pipe 4 closest to the feeding unit 2.

[0032] When adjusting the height of the feeding unit 2, the handle 205 is used to rotate the mating rod 204. When the mating rod 204 rotates, the feeding wheel 206 is raised or lowered through the cooperation of the driver 202 and the screw 203, so as to adjust the height of the feeding wheel 206.

[0033] When the equipment conveys the pipe 4 to the next induction heat treatment process, the vertical hydraulic cylinder 304 is activated. The output end of the vertical hydraulic cylinder 304 drives the lifting plate 305 to rise. When the lifting plate 305 rises, it lifts the pipe 4 upward. After the pipe 4 is lifted to the designated height, due to the structure of the placement area and the influence of the weight of the pipe 4, the pipe 4 will roll towards the feeding unit 2. When the pipe 4 is sent from the lifting unit 3 to the upper end of the feeding wheel 206, the feeding motor is used to make the feeding wheel 206 rotate. During the rotation of the feeding wheel 206, the friction assists in conveying the pipe 4 to the induction heat treatment process. After the pipe 4 has completely moved to the induction heat treatment process, the equipment starts conveying the next pipe 4 to achieve continuous conveying of the pipe 4.

[0034] Before being placed into the placement area of ​​the pipe rack 1, the pipe 4 often needs to be cut. After cutting, the pipe 4 is cleaned of surface oil, oxide scale, and moisture to ensure the effectiveness of subsequent induction heat treatment. However, dust or other impurities inevitably float in the heat treatment workshop, making the surface of the pipe 4 susceptible to contamination during storage. Furthermore, when drying the moisture on the pipe 4, the inner center often experiences poor drying, leading to moisture residue. Additionally, the neatness of the pipe 4's stacking during rolling affects the accuracy of subsequent feeding, impacting the effectiveness of induction heat treatment. For example, the pipe 4 may enter the heat treatment process prematurely without induction heating being activated, or vice versa. To address these issues, the following improvement plan is proposed: like Figures 1 to 7 As shown, a material sorting unit 5 is also provided on the side of the pipe placement rack 1. The material sorting unit 5 is located on the side of the mesh plate 6. A transverse hydraulic cylinder 8 is provided on the side of the pipe placement rack 1 near the mesh plate 6. The transverse hydraulic cylinder 8 is used to move the mesh plate 6 laterally. The transverse movement of the mesh plate 6 can sort the pipes 4 in the placement area, making the stacking of the pipes 4 more orderly.

[0035] The material straightening unit 5 includes a material straightening tube 501. Inner fan blades 502 and outer fan blades 503 are respectively arranged on the inner and outer sides of the material straightening tube 501. A mating tube 504 is rotatably arranged on the side of the material straightening tube 501 near the tube 4. An annular groove 505 is provided on the side end of the mating tube 504. A first protrusion 506 is provided on the inner side of the annular groove 505, and a second protrusion 507 is provided on the outer side of the material straightening tube 501. When the material straightening tube 501 rotates, it drives the inner fan blades 502 and outer fan blades 503 to rotate, thereby causing the inner and outer sides of the material straightening tube 501 to produce… The system generates airflow to transport hot air from the heat treatment process to the pipe 4 placement area, thereby achieving a drying effect. With the assistance of the transverse hydraulic cylinder 8, when the mating pipe 504 is attached to the side of the pipe 4, the rotation of the material tube 501, aided by the first protrusion 506 and the second protrusion 507, also drives the mating pipe 504 to rotate, thus causing the pipe 4 to rotate. The rotation of the pipe 4 is intermittent, and the friction between the pipes during rotation helps to clean the deposits on the outside of the pipe 4.

[0036] The material tube 501 is rotatably inserted into the annular groove 505. The first protrusion 506 and the second protrusion 507 are matched. The mating tube 504 is inclined on the side away from the material tube 501. A rubber sleeve is provided on the outside of the inclined end of the material tube 501. The mating tube 504 is rotatably engaged with the mesh plate 6 and passes through the mesh plate 6. When the mating tube 504 is not in contact with the tube 4, the rotation of the material tube 501 can stably drive the mating tube 501 with the assistance of the first protrusion 506 and the second protrusion 507. The rotation of the fitting tube 504, after the fitting tube 504 is tightly attached to the tube 4, the rotation of the integral tube 501, with the assistance of the first protrusion 506 and the second protrusion 507, can drive the fitting tube 504 to rotate intermittently. This is because after the fitting tube 504 is tightly attached to the tube 4, the force required to drive the fitting tube 504 to rotate stably increases, and the intermittent rotation of the tube 4 is beneficial to cooperate with other tubes 4 to produce a cleaning effect on the surface of the tube 4. When the fitting tube 504 is tightly attached to the tube 4, the tube 4 is protected by a rubber sleeve.

[0037] The material tube 501 is provided with a mounting hole 508, and a mounting arc plate 509 is provided inside the mounting hole 508. A mounting rod 510 is provided on the mounting arc plate 509. The inner fan blade 502 and the outer fan blade 503 are respectively provided on both sides of the mounting rod 510. The size of the inner fan blade 502 is smaller than that of the mounting hole 508. The mounting arc plate 509 is fixed to the material tube 501 by bolts and nuts. When installing the inner fan blade 502 and the outer fan blade 503, the inner fan blade 502 and the outer fan blade 503 are first installed on both sides of the mounting rod 510. Then, the mounting arc plate 509 with the inner fan blade 502 and the outer fan blade 503 is installed. During the installation process, the inner fan blade 502 passes through the mounting hole 508 and enters the interior of the material tube 501. Then, the mounting arc plate 509 is made to fit with the hole near the mounting hole 508. The mounting arc plate 509 is fixed to the mounting hole 508 with the help of bolts and nuts.

[0038] A first mounting bracket 511 is provided on the side of the pipe placement rack 1, and a stabilizing bracket 512 is provided on the upper end of the first mounting bracket 511. The material tube 501 is rotatably mounted on the stabilizing bracket 512. When the material tube 501 rotates, one end of the material tube 501 is assisted by the stabilizing bracket 512, and the other end of the material tube 501 is assisted by the mesh plate 6, so that the rotation of the material tube 501 is more stable.

[0039] A second mounting bracket 513 is provided on the side of the pipe placement rack 1. A drive motor 514 is provided on the second mounting bracket 513. A drive wheel 515 is provided at the output end of the drive motor 514. A driven wheel 516 is provided on the material tube 501. A transmission belt 517 is provided between the drive wheel 515 and the driven wheel 516. When the drive motor 514 is started, the output end of the drive motor 514 drives the drive wheel 515 to rotate. The rotation of the drive wheel 515 drives the rotation of the driven wheel 516 through the assistance of the transmission belt 517. The rotation of the driven wheel 516 can drive the rotation of the material tube 501. The drive motor 514 provides power for the rotation of the material tube 501, making the rotation of the material tube 501 stable and controllable.

[0040] The material straightening tube 501 corresponds to the position of the tube 4 near the side of the feeding unit 2. The tube placement rack 1 is rotatably provided with a driven plate on the opposite side of the material straightening unit 5. The driven plate matches the position of the material straightening tube 501. When the tube 4 rotates, it is assisted by the driven plate to reduce the friction between the tube 4 and the mesh plate 6 on the other side. The driven plate also has mesh holes.

[0041] During use, the horizontal hydraulic cylinder 8 is activated by the lifting unit 3.

[0042] After the equipment is started, the drive motor 514 remains running. After starting, the output end of the drive motor 514 drives the drive wheel 515 to rotate. The rotation of the drive wheel 515 will drive the driven wheel 516 to rotate through the transmission belt 517, thereby making the material tube 501 rotate stably. During the rotation of the material tube 501, the inner fan blade 502 and the outer fan blade 503 will generate wind near the material tube 501. Since the material unit 5 is located on the side close to the heat treatment process, the hot air from the heat treatment process will move towards the placement area of ​​the tube 4 under the action of the wind, so as to achieve the overall drying effect of all the tubes 4.

[0043] When the output end of the vertical hydraulic cylinder 304 of the lifting unit 3 rises, the horizontal hydraulic cylinder 8 controls the straightening unit 5 to move away from the pipe 4. When the output end of the vertical hydraulic cylinder 304 of the lifting unit 3 falls, the horizontal hydraulic cylinder 8 controls the straightening unit 5 to move closer to the pipe 4. Through such control, the operation of the straightening unit 5 and the lifting unit 3 does not affect each other.

[0044] When the material preparation unit 5 moves toward the pipe 4, the mesh plates 6 on both sides cooperate to prepare the pipe 4 in the middle, making the placement of the pipe 4 more orderly.

[0045] As the material preparation unit 5 moves toward the pipe 4, the mating pipe 504 gradually approaches the pipe 4. During the process of the mating pipe 504 approaching the pipe 4, the airflow inside the material preparation pipe 501 gradually converges into the pipe 4, causing hot air to flow into the pipe 4 under the action of the airflow. As the hot air passes through the inside of the pipe 4, the inside of the pipe 4 is dried, reducing the residual moisture inside the pipe 4.

[0046] After the mating tube 504 is tightly attached to the pipe 4, the transverse hydraulic cylinder 8 stops operating. At this time, the rotation of the material tube 501, assisted by the first protrusion 506 and the second protrusion 507, will drive the mating tube 504 to rotate intermittently, thereby causing the pipe 4 to rotate intermittently. During the intermittent rotation of the pipe 4, it rubs against the nearby pipe 4, which cleans the impurities attached to the outside of the pipe 4. Furthermore, under the action of wind, it is beneficial to blow away the cleaned impurities, reducing the impurities on the outside of the pipe 4.

[0047] When the material tube 501 rotates, the rotation of the first protrusion 506 and the second protrusion 507 will generate vibration. The rotation of the material tube 501 can carry the second protrusion 507 across the first protrusion 506. Due to the contact vibration of the first protrusion 506 and the second protrusion 507, the tube 4 in contact with the mating tube 504 will also generate vibration. This is beneficial for cleaning the attached impurities on the outside of the tube 4 and improving the effect of subsequent heat treatment processing of the tube 4.

[0048] Then, when the output end of the vertical hydraulic cylinder 304 of the lifting unit 3 is lifted, the straightening unit 5 moves away from the pipe 4 with the assistance of the horizontal hydraulic cylinder 8. The lifting plate 305 lifts the cleaned pipe 4. When the pipe 4 is lifted, the wind force on the inside and outside of the straightening pipe 501 will supplement the air force to dry and clean the contact area between the pipe 4 and the adjacent pipe 4, so that the pipe 4 will have a better effect when it undergoes subsequent induction heat treatment.

[0049] The main function achieved by this invention is as follows: by setting up components such as lifting unit 3, material straightening pipe 501, inner fan blade 502, outer fan blade 503, and matching pipe 504, and through the coordinated control of lifting unit 3 and transverse hydraulic cylinder 8, the equipment performs a material straightening operation on the remaining pipe 4 each time it lifts and feeds it, ensuring the accuracy of pipe feeding. When the material straightening unit 5 is not close to the pipe 4, the rotation of the material straightening pipe 501, with the assistance of inner fan blade 502 and outer fan blade 503, generates airflow, allowing the hot air from the heat treatment process area to be blown toward the pipe. The placement area 4 enables auxiliary drying and dust removal of the entire pipe 4. When the material preparation unit 5 approaches the pipe 4, the airflow inside the material preparation tube 501 can precisely dry the inside of the pipe 4 to be lifted and blow out impurities. When the mating tube 504 is close to the pipe 4, the material preparation tube 501, with the assistance of the first protrusion 506 and the second protrusion 507, can make the mating tube 504 rotate intermittently, thereby causing the pipe 4 to rotate intermittently and generate vibration, so that the pipe 4 rubs against the adjacent pipe 4 to clean the external attachments of the pipe 4.

[0050] The automatic pipe material handling device of the present invention can be installed, connected or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.
