Description

Technical Field

[0001] This invention relates to an automated production line for copper tube gear rolling, belonging to the field of copper tube gear rolling technology. Background Technology

[0002] In the field of refrigeration technology, it is common practice to process different tooth shapes on copper tubes to increase the heat exchange area of ​​the tubes. The equipment used to process the tooth shape on the tubes is a tooth rolling machine. The tooth rolling machine includes a pre-processing module, a main module, and a post-processing module. The main module is located between the pre-processing module and the post-processing module. For example, Chinese invention patent with authorization announcement number CN119216435B discloses a tube tooth rolling machine and tooth rolling method. The pre-processing module of the tooth rolling machine is mainly responsible for conveying the mandrel to ensure that the mandrel can be inserted into the tube to be processed and to support the tube to be toothed. The post-processing module is mainly responsible for feeding the tube to be processed and unloading the tube after tooth rolling.

[0003] Existing tube rolling mills typically have three rolling mills positioned at the front and two at the back of the production line. For example, Chinese invention patent CN114734268B discloses an automated production line and method for heat exchanger tubes, where loading and unloading of the rolling mills is accomplished by a conveying device positioned above the rolling mills. However, this layout has the following drawbacks: First, this layout, with three rolling mills in a row, occupies a significant amount of space in the factory. If a loading line were set up on the first floor of the workshop, more than one loading line would be needed, further increasing the space requirement. Therefore, currently, only an overhead conveying device can be used for loading and unloading. Second, the overhead conveying device above the rolling mills... During loading and unloading, the pipe fittings gripped by the handle may fall and impact the gear rolling mill or operators, posing a safety hazard. The loading and unloading of the handling device also involves the downward and upward movements of the handle, affecting the loading and unloading rhythm of the gear rolling mill. Finally, the existing pipe fitting gear rolling lines have some low capacity requirements. For example, a steel pipe gear rolling line only needs five gear rolling mills to meet its capacity requirements. However, for copper pipe gear rolling lines, the capacity requirements are high, and up to 30 gear rolling mills are needed to meet the capacity requirements. The workshop of a copper pipe gear rolling production line is generally built to be relatively long, but its width is limited. If three gear rolling mills are arranged in a row, the length space is not fully utilized, while the width space is very tight, resulting in the inefficient use of factory space. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing an automated production line for copper tube gear rolling.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: An automated production line for copper tube gear rolling includes multiple gear rolling mills for copper tube gear rolling. Each gear rolling mill includes a gear rolling main module, a pre-processing module located in front of the gear rolling main module, and a post-processing module located behind the gear rolling main module. It also includes a feeding line for feeding tube material to the multiple gear rolling mills. The feeding line includes multiple feeding conveying mechanisms, which are connected end-to-end or spaced apart. The multiple gear rolling mills are symmetrically arranged on both sides of the feeding line.

[0006] It also includes a feeding assembly for supplying tubes to the feeding line; the feeding assembly includes a feeding conveying mechanism, a lifting and distributing mechanism, a feeding buffer mechanism, and a longitudinal conveying mechanism; the feeding conveying mechanism includes a feeding frame and multiple feeding conveying units disposed on the feeding frame, each feeding conveying unit includes a feeding conveying chain and multiple conveying accessories disposed on the feeding conveying chain, the conveying accessories forming a conveying storage area for storing copper tubes; the feeding buffer mechanism includes a feeding buffer frame, the feeding buffer frame is provided with a buffer section and a discharge guide section, the bearing surfaces of the buffer section and the discharge guide section are both inclined with the discharge side lower than the inlet side;

[0007] The lifting and distributing mechanism includes at least one lifting and distributing unit, which includes a primary lifting frame and a secondary lifting frame. The bearing surfaces of both the primary and secondary lifting frames are inclined so that the discharge side is lower than the infeed side. The primary lifting frame can lift the copper tubes in the adjacent conveying and storage area to the buffer section. The secondary lifting frame can lift a single copper tube located in the buffer section to the discharge guide section. The single copper tube is conveyed to the longitudinal conveying mechanism through the discharge guide section. The longitudinal conveying mechanism is arranged in a straight line with the feeding line. The longitudinal conveying mechanism receives the copper tube and can longitudinally convey it to the feeding conveying mechanism. Under the action of the feeding conveying mechanism, the copper tube can be longitudinally conveyed to the corresponding gear rolling mill that is short of material, and can also be transversely conveyed to feed the gear rolling mill that is short of material.

[0008] The beneficial effects of this invention are as follows: Multiple gear rolling mills can be symmetrically arranged on both sides of the feeding line along its centerline. A single feeding line located on the first floor of the workshop can supply copper tubes to these multiple mills. This rational arrangement of the mills efficiently utilizes factory space, resulting in high workshop utilization and meeting the copper tube gear rolling capacity requirements. Since both the feeding line and the gear rolling mills are located on the first floor of the workshop, there is no need for overhead truss transport of copper tubes, enhancing equipment and personnel safety. The copper tube supply to the feeding line can be achieved through the feeding assembly. Considering the relatively soft texture of copper tubes and their inability to be compressed, the storage of copper tubes is partitioned. Multiple conveying attachments on the feeding conveyor mechanism form multiple conveying and storage areas. Copper tubes can be stored in these areas. Under the action of the feeding conveyor chain, the conveying attachments carry the copper tubes towards the discharge side. When one of the conveying and storage areas moves to the point where it aligns with the lifting and distributing mechanism… When the material is in the correct position, the feeding conveyor chain stops conveying, the first-stage lifting frame is raised, and the copper pipe in the conveying storage area is moved upward. When the discharge side of the first-stage lifting frame moves to the position corresponding to the buffer section, the copper pipe at the lower position raised by the first-stage lifting frame moves to the buffer section. The second-stage lifting frame can lift the single copper pipe at the lower position on the buffer section. As the second-stage lifting frame moves upward, the copper pipe can smoothly enter the discharge guide section, and then smoothly enter the longitudinal conveying mechanism. The longitudinal conveying mechanism can longitudinally convey the copper pipe to the feeding line. According to the position of the material shortage gear rolling mill, the copper pipe entering the feeding line will continue to be longitudinally conveyed under the action of the feeding conveying mechanism until it reaches the corresponding material shortage gear rolling mill position. Then, under the action of the feeding conveying mechanism, the copper pipe can be transversely conveyed to the feeding section of the post-processing module of the material shortage gear rolling mill. After that, the copper pipe enters the processing area of ​​the gear rolling mill for gear rolling operation. In summary, the layout of the gear rolling mill of this invention is reasonable, making full use of the space in the factory workshop. The material supply assembly and one feeding line on the first floor of the workshop can meet the copper tube supply needs of multiple gear rolling mills. The automatic feeding and feeding of copper tubes is highly efficient and can meet the production rhythm of multiple gear rolling mills. The copper tube conveying process is stable and reliable, avoiding the risk of falling off during aerial conveying and ensuring the safety of equipment and personnel.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the feeding and conveying mechanism includes a feeding and conveying frame, a plurality of feeding and conveying rollers rotatably mounted on the feeding and conveying frame, a feeding and conveying roller drive mechanism for driving the feeding and conveying rollers to rotate, a transverse conveying mechanism mounted on both sides of the feeding and conveying frame, and a feeding and lifting assembly for lifting the copper tubes on the feeding and conveying rollers; the feeding and conveying frame is also provided with a discharge guide mechanism for guiding the copper tubes lifted by the feeding and lifting assembly to the discharge guide mechanism on the transverse conveying mechanism, and the transverse conveying mechanism is used to transversely convey the copper tubes to the feeding section of the post-processing module of the gear rolling mill.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the transverse conveying mechanism is set at the position corresponding to the post-processing module of the gear rolling mill. The copper tube can be longitudinally conveyed on the feeding conveying mechanism to the position corresponding to the gear rolling mill that is short of material, and then the transverse conveying mechanism sends the copper tube to the feeding section of the post-processing module of the gear rolling mill. After the copper tube is longitudinally conveyed to the position by the feeding conveying mechanism, the feeding lifting component can lift the copper tube, and with the help of the discharge guiding mechanism, the copper tube can smoothly enter the transverse conveying mechanism. The transverse conveying mechanism can transversely convey the copper tube to the feeding section of the post-processing module of the gear rolling mill, and then the copper tube can enter the processing area of ​​the gear rolling mill for gear rolling operation.

[0012] Furthermore, the transverse conveying mechanism includes a conveying arm shaft rotatably mounted on the feeding conveyor frame, a plurality of transverse conveying arms mounted on the conveying arm shaft, and a rotation drive mechanism for driving the conveying arm shaft to rotate.

[0013] The beneficial effects of adopting the above-mentioned further solution are that the transverse conveying arm can extend to the feeding section of the post-processing module of the gear rolling mill, ensuring that the copper tubes can be smoothly supplied to the gear rolling mill after transverse conveying. Under the action of the rotation drive mechanism, the transverse conveying arm can flexibly adjust its angle and position so that it can accurately connect to the feeding section of the post-processing module of the gear rolling mill. The stable rotation of the conveying arm shaft ensures the synchronous operation of multiple transverse conveying arms, thereby realizing the continuous and efficient transverse conveying of copper tubes. When it is not necessary to transversely convey copper tubes to the gear rolling mill, the transverse conveying arm can also be retracted into a vertical state under the action of the rotation drive mechanism, which can clear the passage and facilitate the operator to inspect and maintain the gear rolling mill.

[0014] Furthermore, the gear rolling mills located on one side of the feeding line are arranged in two rows, namely, the far-side gear rolling mills away from the feeding line and the near-side gear rolling mills close to the feeding line. The far-side gear rolling mills and the near-side gear rolling mills are arranged alternately. The pre-processing module of the gear rolling mill located on the same side and the post-processing module of the adjacent gear rolling mill are arranged horizontally in correspondence.

[0015] The beneficial effects of adopting the above-mentioned further scheme are that the post-processing module of the gear rolling mill is used for the feeding and unloading of copper tubes. Multiple gear rolling mills located on one side of the feeding line are arranged in two rows and staggered. For example, after the gear rolling mills on the far side are arranged in one row, the post-processing module of the gear rolling mill on the near side can be set up in a horizontal correspondence with the pre-processing module of the gear rolling mill on the far side, and the pre-processing module of the gear rolling mill on the near side can be set up in a horizontal correspondence with the post-processing module of the gear rolling mill on the far side. The staggered gear rolling mills will not interfere with each other. This can further shorten the length of the feeding line, shorten the longitudinal conveying distance of the copper tubes, improve the conveying efficiency of the copper tubes, further optimize the utilization of the length and width of the plant space, make the layout of the copper tube gear rolling production line more compact and reasonable, improve the continuity of the copper tube gear rolling production process, and further improve the production efficiency of copper tube gear rolling.

[0016] Furthermore, it also includes a feeding transition mechanism, which is disposed between the near-side gear mill and the far-side gear mill;

[0017] The feeding transition mechanism includes a transition frame, a transition conveying shaft rotatably mounted on the transition frame, multiple transition conveying arms mounted on the transition conveying shaft, and a transition drive mechanism for driving the transition conveying shaft to rotate. The copper tubes that are transversely conveyed by the transverse conveying mechanism can be fed to the gear rolling mill through the transition conveying arms.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the gear rolling mills on one side of the feeding line are arranged in two rows. When it is necessary to supply copper tubes to the gear rolling mills on the near side, the transverse conveying arm of the transverse conveying mechanism can directly extend to the feeding part of the post-processing module of the gear rolling mill. However, for the gear rolling mills on the far side, the length of the transverse conveying arm of the transverse conveying mechanism is limited. If its length is forcibly extended, there is a problem that the transverse conveying arm cannot stably support the copper tube. Therefore, a feeding transition mechanism can be added. In this way, the copper tubes that have passed through the transverse conveying can smoothly enter the transition conveying arm. The transition conveying arm can smoothly supply copper tubes to the gear rolling mills on the far side. The feeding line can not only meet the copper tube supply needs of the gear rolling mills arranged in close proximity, but also meet the copper tube supply needs of the gear rolling mills arranged in a relatively far distance.

[0019] Furthermore, the feeding transition mechanism also includes a deceleration conveying assembly, which includes a deceleration shaft rotatably mounted on the transition frame, a plurality of deceleration baffles mounted on the deceleration shaft, and a deceleration drive mechanism for driving the deceleration shaft to rotate. The deceleration baffles can block the copper tube under the action of the deceleration drive mechanism.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the deceleration baffle can effectively control the speed of the copper tube during the transition conveying process under the drive of the deceleration drive mechanism, avoid the copper tube position deviation or impact damage caused by the copper tube moving too fast, so that the copper tube can be smoothly conveyed laterally to the feeding part of the post-processing module of the gear rolling mill. The deceleration conveying component can automatically decelerate the copper tube, reduce manual intervention, reduce the impact of the copper tube, and improve the stability of the copper tube lateral conveying.

[0021] Furthermore, the deceleration conveying assembly also includes a deceleration frame, which is fixedly connected to the transition conveying shaft, and the deceleration shaft is rotatably connected to the deceleration frame. The transition conveying arm is provided with a shaft hole for the deceleration shaft to pass through, and the deceleration shaft is rotatably connected to the transition conveying arm.

[0022] The beneficial effects of adopting the above-mentioned further solution are that when the reduction shaft rotates, the reduction baffle can block the copper tube, thereby slowing down the copper tube and reducing the impact on the copper tube. On the one hand, the reduction frame can meet the requirements of the reduction shaft rotation, and on the other hand, the conveying angle of the transition conveying arm can be adjusted, specifically by the rotation of the transition conveying shaft. The reduction frame connects the reduction shaft and the transition conveying shaft as a whole. In this way, when the transition conveying shaft rotates, not only can the tilt angle of the transition conveying arm be adjusted, but the reduction frame and the reduction shaft also rotate together with the transition conveying arm, enhancing the structural stability of the feeding transition mechanism, providing reliable support for the reduction shaft, and also meeting the requirements of transverse transition conveying of the copper tube.

[0023] Furthermore, the secondary lifting frame is adjustablely positioned on the primary lifting frame, and an adjustment mechanism for assisting in adjusting the position of the secondary lifting frame is provided between the secondary lifting frame and the feeding buffer frame. The adjustment mechanism includes a first stop wheel and a second stop wheel that are adjustablely positioned on the feeding buffer frame, and an adjustment guide plate that is positioned on the secondary lifting frame. A guide plate limiting channel for positioning the adjustment guide plate is formed between the first stop wheel and the second stop wheel.

[0024] The beneficial effect of adopting the above-mentioned further solution is that, for copper pipes with different diameters, when the primary lifting frame carries a copper pipe from a conveying and storage area upwards, for small-diameter copper pipes, there may be more than one copper pipe entering the buffer section. The position of the secondary lifting frame can be adjusted according to the diameter of the copper pipe, thereby ensuring that the secondary lifting frame only lifts a single copper pipe into the discharge guide section during lifting. Specifically, the positions of the first stop wheel and the second stop wheel are adjusted according to the diameter of the copper pipe, thereby adjusting the position of the guide plate limiting channel. In this way, the position of the secondary lifting frame is adjusted by the adjusting guide plate that cooperates with the guide plate limiting channel, so as to achieve the purpose of the secondary lifting frame lifting a single copper pipe into the discharge guide section. The secondary lifting frame is installed on the primary lifting frame. When the primary lifting frame is lifted, it carries the copper pipes in the adjacent conveying and storage area upwards. When the primary lifting frame is raised to the position corresponding to its discharge side and the buffer section, the copper pipes at the lower position lifted by the primary lifting frame will smoothly enter the buffer section. The buffer section contains the copper pipes lifted by the primary lifting frame. Then the primary lifting frame is reset. After that, the primary lifting frame is raised again. The secondary lifting frame is higher than the primary lifting frame. As the primary lifting frame is raised, the secondary lifting frame lifts the single copper pipe on the buffer section. The single copper pipe is raised to the position corresponding to the inlet side of the discharge guide section and can smoothly enter the discharge guide section. The lifting of the primary lifting frame continues to move the copper pipes in the conveying and storage area upwards into the buffer section. Under the guidance of the discharge guide section, the single copper pipe will smoothly enter the conveying mechanism, realizing the feeding of single copper pipes.

[0025] Furthermore, it also includes multiple receiving mechanisms, which are correspondingly arranged on the discharge side of the post-processing module of the gear rolling mill;

[0026] The receiving mechanism includes a receiving frame, a receiving assembly mounted on the receiving frame, and a discharging assembly; the receiving assembly includes a receiving shaft rotatably mounted on the receiving frame, a plurality of receiving arms mounted on the receiving shaft, a liquid receiving tray mounted between the receiving arms, and a receiving drive mechanism for driving the receiving shaft to rotate.

[0027] The discharge assembly includes a discharge shaft rotatably mounted on the receiving frame, a plurality of discharge arms mounted on the discharge shaft, a liquid discharge plate disposed between the discharge arms, and a discharge drive mechanism for driving the discharge shaft to rotate, wherein the liquid discharge plate is located below the liquid receiving plate.

[0028] The beneficial effect of adopting the above-mentioned further solution is that after the copper tube completes the gear rolling process on the gear rolling mill, it is sometimes immersed in the dilution tank on the discharge side of the post-processing module of the gear rolling mill for a certain period of time. The copper tube coming out of the dilution tank will carry a certain amount of liquid. If it is directly discharged into the unloading line of the workshop, the liquid will drip into the workshop. Therefore, a receiving mechanism is added between the dilution tank on the discharge side of the post-processing module of the gear rolling mill and the unloading line. After the copper tube comes out of the dilution tank, it can enter the receiving arm. The receiving arm can be adjusted in tilt under the action of the receiving drive mechanism, so that the copper tube can pass smoothly through the receiving arm and move to the discharge arm. The discharge arm can also be adjusted in tilt angle under the action of the discharge drive mechanism, so that the copper tube can pass smoothly through the receiving mechanism. The receiving mechanism has a liquid receiving tray and a liquid discharge tray to collect the liquid dripping from the copper tube, which can keep the workshop floor dry and clean.

[0029] Furthermore, the receiving mechanism also includes a receiving blocking assembly, which includes a receiving blocking shaft, a plurality of receiving blocks disposed on the receiving blocking shaft, and a blocking shaft driving mechanism for driving the receiving blocking shaft to rotate. The receiving blocking shaft is rotatably disposed at the discharge end of the discharge arm.

[0030] The beneficial effect of adopting the above-mentioned further solution is that the receiving stop shaft can rotate under the action of the stop shaft drive mechanism, and the receiving stop block can rotate with the receiving stop shaft. The blocking position and angle can be adjusted according to actual needs. The receiving stop assembly can block the copper tube entering the receiving mechanism, reducing the impact on the copper tube. The receiving stop block of the receiving stop assembly can rotate down and no longer block the copper tube, so that the copper tube can smoothly enter the unloading line, ensuring the dryness and cleanliness of the workshop floor.

[0061] The lifting and distributing mechanism includes at least one lifting and distributing unit. The lifting and distributing unit is located on the discharge side of the feeding and conveying mechanism and between adjacent feeding and conveying units. The lifting and distributing unit includes a primary lifting frame 107 and a secondary lifting frame 108 mounted on the primary lifting frame 107. The bearing surfaces of both the primary lifting frame 107 and the secondary lifting frame 108 are inclined so that the discharge side is lower than the inlet side. The primary lifting frame 107 can lift the copper tubes in the adjacent conveying and storage area to the buffer section 105. The secondary lifting... The frame 108 can lift a single copper tube located in the buffer section 105 to the discharge guide section 106, and the single copper tube is conveyed to the longitudinal conveying mechanism through the discharge guide section 106. The longitudinal conveying mechanism is arranged in a straight line with the feeding line. The longitudinal conveying mechanism receives the copper tube and can convey it longitudinally to the feeding conveying mechanism 200. Under the action of the feeding conveying mechanism 200, the copper tube can be conveyed longitudinally to the corresponding tooth rolling mill 500 that is short of material, and can be conveyed laterally to feed the tooth rolling mill 500 that is short of material.

[0062] The conveying accessory 103 includes a base plate, a front baffle, and a rear baffle disposed on the feeding conveyor chain 102, and the base plate, the front baffle, and the rear baffle are respectively connected to the feeding conveyor chain 102.

[0064] The feeding assembly 100's feeding and conveying mechanism can store copper tubes. The first-stage lifting frame 107 of the lifting and distributing mechanism can lift the copper tubes near the discharge side of the conveying and storage area. Under the lifting action of the first-stage lifting frame 107, the lower-positioned copper tubes can be moved to the buffer section 105 on the feeding buffer frame 104. The second-stage lifting frame 108 can lift the lower-positioned single copper tubes on the buffer section 105 and can laterally convey the copper tubes to the longitudinal conveying mechanism. The longitudinal conveying mechanism is used for the longitudinal conveying of copper tubes and can convey the copper tubes to the loading conveying mechanism 200. The loading conveying mechanism 200 has a longitudinal conveying section. The longitudinal conveying section includes a longitudinal conveying roller 202 for conveying copper tubes longitudinally to ensure accurate arrival of the copper tubes at the corresponding position of the tooth rolling mill 500 when it is short of material. The transverse conveying section then transversely conveys the longitudinally conveyed copper tubes to the tooth rolling mill 500 when it is short of material. The loading lifting assembly, the discharge guiding mechanism, and the transverse conveying mechanism can all be installed on the transverse conveying section. The loading lifting assembly is used to switch the copper tubes from longitudinal to transverse conveying, which can complete the transfer process of the copper tubes in a short time. The discharge guiding mechanism is used to guide the copper tubes lifted by the loading lifting assembly to the transverse conveying arm 204.

[0065] The feeding and lifting assembly includes a feeding and lifting beam 206, multiple feeding and lifting plates 207 mounted on the feeding and lifting beam 206, and a feeding and lifting drive cylinder 208 for driving the feeding and lifting beam 206 up and down. The bearing surface of the feeding and lifting plates 207 is inclined with the inner side higher than the outer side. Two sets of feeding and lifting assemblies are provided on the feeding conveying mechanism 200. One set can lift the copper tube and, guided by the discharge guide mechanism, feed it to the gear mill 500 on one side of the feeding line. The other set of feeding and lifting assemblies can lift the copper tube and, guided by the discharge guide mechanism on the corresponding side, feed it to the gear mill 500 on the other side of the feeding line. The feeding and lifting beam 206 can move up and down under the action of the feeding and lifting drive cylinder 208, and the multiple feeding and lifting plates 207 move synchronously with the feeding and lifting beam 206. The lifting mechanism can smoothly lift the copper tube from a low position to a high position. During the upward movement of the copper tube, the vertical plate of the discharge guide plate 205 can limit the copper tube until the loading lifting plate 207 is raised to the point where the copper tube can pass through the inclined plate of the corresponding discharge guide plate 205 and move smoothly to the transverse conveying mechanism on the corresponding side. The loading lifting assembly lifts the copper tube that is conveyed longitudinally and guides it through the discharge guide mechanism on the corresponding side before entering the transverse conveying, thereby improving the conveying efficiency of the copper tube and reducing the risk of slippage.

[0066] The transverse conveying mechanism includes a conveying arm shaft 203 rotatably mounted on the feeding conveyor frame 201, multiple transverse conveying arms 204 mounted on the conveying arm shaft 203, and a rotation drive mechanism for driving the conveying arm shaft 203 to rotate. The transverse conveying arms 204 can extend to the post-processing module 502 of the gear rolling mill 500, ensuring a smooth supply of copper tubes to the gear rolling mill 500. Under the action of the rotation drive mechanism, the transverse conveying arms 204 can flexibly adjust their angle and position to precisely align with the feeding section of the post-processing module 502 of the gear rolling mill 500. The stable rotation of the conveying arm shaft 203 ensures the synchronous operation of the multiple transverse conveying arms 204, thereby achieving continuous and efficient transverse conveying of copper tubes. When transverse conveying of copper tubes to the gear rolling mill 500 is not required, the transverse conveying arms 204 can also be retracted into a vertical position under the action of the rotation drive mechanism, freeing up a passage for operators to inspect and maintain the gear rolling mill 500.

[0067] The transverse conveying mechanism also includes a transverse extension arm, which is connected to the transverse conveying arm 204. This extension arm increases the support strength of the transverse conveying arm 204 and extends its length.

[0068] The rotation drive mechanism includes a rotation drive cylinder 211, the cylinder body of which is hinged to the feeding conveyor frame 201. The piston rod of the rotation drive cylinder 211 is connected to the conveying arm shaft 203 via a connecting arm. One end of the connecting arm is connected to the conveying arm shaft 203, and the other end is hinged to the rotation drive cylinder 211.

[0069] Both the feeding conveyor roller 202 and the supply conveyor roller 120 have a V-shaped roller structure. The conveying of copper tubes on the supply conveyor roller 120 and the feeding conveyor roller 202 is more stable and reliable.

[0070] The discharge guiding mechanism includes multiple discharge guide plates 205, which are arranged along the length of the feeding conveyor frame 201. The bearing surface of each discharge guide plate 205 is inclined with a higher inner surface and a lower outer surface. The discharge guiding mechanism is located on both sides of the feeding conveyor frame 201, and can laterally convey copper tubes from the gear rolling mills 500 located on both sides of the feeding line. Each discharge guide plate 205 includes a vertical plate and an inclined plate. The vertical plate can limit the movement of the copper tube during the lifting process, and the inclined plate can guide the lifted copper tube onto the transverse conveying arm 204. The inclined arrangement of the inclined plate of the discharge guide plate 205 better guides the copper tube to smoothly transition from longitudinal to transverse conveying. The multiple discharge guide plates 205 distributed along the length of the feeding conveyor frame 201 ensure that the copper tube receives effective guiding support, further improving the stability and efficiency of the copper tube conveying process.

[0071] The feeding conveyor roller drive mechanism includes two feeding transmission gears 209 mounted on the roller shaft of the feeding conveyor roller 202, a feeding drive motor 210 mounted on the feeding conveyor frame 201, and a feeding drive gear mounted on the output shaft of the feeding drive motor 210. The feeding drive gear is connected to one of the feeding transmission gears 209 of one of the feeding conveyor rollers 202 via a feeding drive chain, and the feeding transmission gears 209 between adjacent feeding conveyor rollers 202 are connected via a feeding drive chain. The copper tubes on the feeding line are conveyed by the feeding conveyor rollers 202. Even with the feeding conveyor mechanisms 200 set at intervals, the copper tubes must be stably conveyed between adjacent feeding conveyor mechanisms 200. The power of the feeding conveyor rollers 202 is provided by the feeding drive motor 210. When the feeding drive motor 210 is activated, it can transmit power to one feeding conveyor roller 202 of the feeding conveyor mechanism 200 through the feeding drive gear and feeding drive chain. The feeding conveyor rollers 202 adjacent to it can be driven to rotate through the cooperation of the feeding transmission gear 209 and the feeding transmission rack. The feeding drive motor 210 provides power, and through the transmission of gears and chains, the rotation drive of the feeding conveyor rollers 202 is realized, thereby realizing the smooth longitudinal conveying of the copper tubes on the feeding conveyor mechanism 200 of the feeding line.

[0072] The gear rolling mills 500 located on one side of the feeding line are arranged in two rows, namely, the far-side gear rolling mills away from the feeding line and the near-side gear rolling mills close to the feeding line. The far-side gear rolling mills and the near-side gear rolling mills are arranged alternately. The pre-processing module 501 of the gear rolling mill 500 and the post-processing module 502 of the adjacent gear rolling mill 500 are arranged horizontally in correspondence. The post-processing module 502 of the gear rolling mill 500 is used for feeding and unloading copper tubes. Multiple gear rolling mills 500 located on one side of the feeding line are arranged in two rows and staggered. For example, after the gear rolling mills on the far side are arranged in one row, the post-processing module 502 of the gear rolling mills on the near side can be set horizontally in correspondence with the pre-processing module 501 of the gear rolling mills on the far side, and the pre-processing module 501 of the gear rolling mills on the near side can be set horizontally in correspondence with the post-processing module 502 of the gear rolling mills on the far side. The staggered gear rolling mills 500 will not interfere with each other. This can further shorten the length of the feeding line, shorten the longitudinal conveying distance of the copper tubes, improve the conveying efficiency of the copper tubes, and further optimize the utilization of the length and width of the plant space, making the layout of the copper tube gear rolling production line more compact and reasonable, improving the continuity of the copper tube gear rolling production process, and further improving the production efficiency of copper tube gear rolling.

[0073] It also includes a feeding transition mechanism 300, which is disposed between the near-side gear mill and the far-side gear mill;

[0074] The feeding transition mechanism 300 includes a transition frame 301, a transition conveying shaft 302 rotatably mounted on the transition frame 301, a plurality of transition conveying arms 303 mounted on the transition conveying shaft 302, and a transition drive mechanism for driving the transition conveying shaft 302 to rotate. The copper tubes transversely conveyed by the transverse conveying mechanism can be fed to the gear rolling mill 500 through the transition conveying arms 303.

[0075] The transition drive mechanism includes a transition drive cylinder 304. The transition drive cylinder 304 is mounted on the transition frame 301, and the piston rod of the transition drive cylinder 304 is connected to the transition conveying shaft 302 via a transition connecting rod.

[0076] The feeding transition mechanism 300 also includes a deceleration conveying assembly, which includes a deceleration shaft 305 rotatably mounted on the transition frame 301, a plurality of deceleration baffles 306 mounted on the deceleration shaft 305, and a deceleration drive mechanism for driving the deceleration shaft 305 to rotate. The deceleration baffles 306 can block the copper tube under the action of the deceleration drive mechanism.

[0077] The deceleration drive mechanism includes a deceleration drive cylinder 307, and the piston rod of the deceleration drive cylinder 307 is connected to the deceleration shaft 305 through a deceleration connecting rod.

[0078] The deceleration conveying assembly also includes a deceleration frame 308, which is fixedly connected to the transition conveying shaft 302. The deceleration shaft 305 is rotatably connected to the deceleration frame 308. The transition conveying arm 303 is provided with a shaft hole for the deceleration shaft 305 to pass through, and the deceleration shaft 305 is rotatably connected to the transition conveying arm 303. When the reduction shaft 305 rotates, the reduction baffle 306 can block the copper tube, causing the copper tube to decelerate. The reduction frame 308 can meet the rotation requirements of the reduction shaft 305 on the one hand, and the conveying angle of the transition conveying arm 303 can be adjusted on the other hand, specifically by rotating the transition conveying shaft 302. The reduction frame 308 connects the reduction shaft 305 and the transition conveying shaft 302 as a whole. In this way, when the transition conveying shaft 302 rotates, not only can the tilt angle of the transition conveying arm 303 be adjusted, but the reduction frame 308 and the reduction shaft 305 also rotate together with the transition conveying arm 303, which enhances the structural stability of the feeding transition mechanism 300, provides reliable support for the reduction shaft 305, and can also meet the requirements of transverse transition conveying of the copper tube.

[0079] The secondary lifting frame 108 is adjustablely mounted on the primary lifting frame 107. An adjustment mechanism for assisting in adjusting the position of the secondary lifting frame 108 is provided between the secondary lifting frame 108 and the feeding buffer frame 104. The adjustment mechanism includes a first stop wheel 124 and a second stop wheel 125 that are adjustablely mounted on the feeding buffer frame 104, and an adjustment guide plate 126 mounted on the secondary lifting frame 108. A guide plate limiting channel for positioning the adjustment guide plate 126 is formed between the first stop wheel 124 and the second stop wheel 125.

[0080] The secondary lifting frame 108 is provided with an elongated through hole. The secondary lifting frame 108 is mounted on the discharge side of the primary lifting frame 107 via fasteners. The rod of the fastener passes through the elongated through hole and is threadedly connected to the primary lifting frame 107, thus achieving the installation and positioning of the secondary lifting frame 108. Loosening the fasteners allows adjustment of the position of the secondary lifting frame 108. The first stop wheel 124 and the second stop wheel 125 are rotatably mounted on the stop wheel mounting plate. The stop wheel mounting plate also has an elongated through hole and is connected to the feeding buffer frame 104 via fasteners. Adjusting the position of the first stop wheel 124 or the second stop wheel 125 requires loosening the corresponding fasteners.

[0081] The feeding and conveying unit also includes a drive sprocket 109 and a driven sprocket 110. The feeding and conveying chain 102 is wrapped around the drive sprocket 109 and the driven sprocket 110. The feeding and conveying chain 102 conveys copper tubes under the action of the chain conveying drive mechanism. The drive sprocket 109 rotates under the action of the chain conveying drive mechanism.

[0082] The chain drive mechanism includes a feeding conveyor shaft 111 and a feeding conveyor motor 112 for driving the feeding conveyor shaft 111 to rotate. The feeding conveyor shaft 111 is rotatably mounted on the feeding frame 101, and the drive sprocket 109 of the feeding conveyor unit is mounted on the feeding conveyor shaft 111.

[0083] The lifting and distributing unit also includes a lifting fixing frame 113. The primary lifting frame 107 and the secondary lifting frame 108 are movably mounted on the lifting fixing frame 113. The primary lifting frame 107 is provided with a lifting guide column 114 that cooperates with the lifting fixing frame 113. The lifting and distributing mechanism also includes a lifting drive mechanism, which is used to drive the lifting and distributing actions of the primary lifting frame 107 and the secondary lifting frame 108 of the multiple lifting and distributing units.

[0084] The lifting drive mechanism includes a lifting drive cylinder 115, which is mounted on the lifting fixed frame 113. The piston rod of the lifting drive cylinder 115 is connected to the first-stage lifting frame 107.

[0085] The lifting drive mechanism also includes a lifting transmission mechanism disposed between adjacent lifting and distributing units. The lifting transmission mechanism includes a lifting transmission shaft 116, a lifting transmission gear 117 disposed on the lifting transmission shaft 116, and a lifting transmission rack 118 meshing with the lifting transmission gear 117. The lifting transmission shaft 116 is rotatably disposed on the lifting fixing frame 113 of the plurality of lifting and distributing units, and the lifting transmission rack 118 is correspondingly disposed on the first-stage lifting frame 107 of each lifting and distributing unit. The lifting transmission mechanism can further ensure the synchronization between the lifting and distributing units.

[0086] The longitudinal conveying mechanism includes a longitudinal feeding conveyor frame 119, a plurality of feeding conveyor rollers 120 rotatably mounted on the longitudinal feeding conveyor frame 119, and a feeding conveyor roller drive mechanism for driving the feeding conveyor rollers 120 to rotate.

[0087] The feeding conveyor roller drive mechanism includes two feeding transmission gears 121 mounted on the roller shaft of the feeding conveyor roller 120, a feeding drive motor 123 mounted on the longitudinal feeding conveyor frame 119, and a feeding drive gear 122 mounted on the output shaft of the feeding drive motor 123. The feeding drive gear 122 is connected to one of the feeding transmission gears 121 of one of the feeding conveyor rollers 120 via a feeding drive chain. The feeding transmission gears 121 between adjacent feeding conveyor rollers 120 are connected via a feeding drive chain. When the copper tube enters the longitudinal conveying mechanism, it is longitudinally conveyed under the action of the feeding conveyor roller 120. The longitudinal conveying mechanism can be connected to the feeding conveyor mechanism 200 or there can be a gap. When the gap is set, it should be sufficient to ensure that the copper tube can be stably conveyed longitudinally from the longitudinal conveying mechanism to the feeding conveyor mechanism 200. The power of the feeding conveyor roller 120 is provided by the feeding drive motor 123. When the feeding drive motor 123 is activated, it can transmit power to one feeding conveyor roller 120 of the longitudinal conveying mechanism through the feeding drive gear 122 and the feeding drive chain. The adjacent feeding conveyor rollers 120 can be driven to rotate through the cooperation of the feeding transmission gear 121 and the feeding transmission chain. The feeding drive motor 123 provides power, and through the transmission of gears and chains, the rotation drive of the feeding conveyor rollers 120 is realized, thereby realizing the smooth operation of the copper tube in the longitudinal conveying mechanism.

[0088] Considering that some copper tubes, after being rolled into teeth, are first immersed in the dilution tank on the discharge side of the post-processing module of the gear rolling mill 500 for a certain period of time, as disclosed in Chinese invention patent CN116197186B, a tube cleaning device can be used to clean the copper tubes after rolling. The cleaned copper tubes then enter the unloading line 600 for subsequent processes. This tube cleaning device is already disclosed as prior art and will not be described further here. The copper tubes coming out of the dilution tank may contain certain liquids, such as water or cutting fluid. If they are directly discharged into the unloading line 600 in the workshop, the liquid will drip into the workshop. Therefore, a receiving mechanism 400 can be added between the dilution tank on the discharge side of the post-processing module 502 of the gear rolling mill 500 and the unloading line 600.

[0089] like Figures 23-26 As shown, it also includes multiple receiving mechanisms 400, which are correspondingly arranged on the discharge side of the post-processing module 502 of the gear rolling mill 500.

[0090] The receiving mechanism 400 includes a receiving frame 401, a receiving assembly disposed on the receiving frame 401, and a discharging assembly; the receiving assembly includes a receiving shaft 402 rotatably disposed on the receiving frame 401, a plurality of receiving arms 403 disposed on the receiving shaft 402, a liquid receiving tray 404 disposed between the receiving arms 403, and a receiving drive mechanism for driving the receiving shaft 402 to rotate;

[0091] The discharge assembly includes a discharge shaft 405 rotatably mounted on the receiving frame 401, a plurality of discharge arms 406 mounted on the discharge shaft 405, a liquid discharge plate 407 disposed between the discharge arms 406, and a discharge drive mechanism for driving the discharge shaft 405 to rotate. The liquid discharge plate 407 is located below the liquid receiving plate 404. Figure 23 To clearly demonstrate the material receiving arm 403 and the material discharging arm 406, only a portion of the structure of the liquid receiving tray 404 and the liquid discharging tray 407 is shown.

[0092] The liquid discharge tray 407 is provided with a material tray outlet 411 on the discharge side. Liquid can be discharged and collected centrally through the material tray outlet, which will not pollute the workshop environment and keep the workshop floor dry and clean.

[0093] The receiving mechanism 400 further includes a receiving blocking assembly, which includes a receiving blocking shaft 408, a plurality of receiving blocks 409 disposed on the receiving blocking shaft 408, and a blocking shaft driving mechanism for driving the receiving blocking shaft 408 to rotate. The receiving blocking shaft 408 is rotatably disposed at the discharge end of the discharge arm 406.

[0094] The discharge shaft 405 is also provided with a support frame 410. The other end of the support frame 410 is rotatably connected to the receiving stop shaft 408. The stop shaft driving mechanism is disposed on the support frame 410, and the driving end of the stop shaft driving mechanism is connected to the receiving stop shaft 408 through a stop shaft connecting rod. The receiving stop shaft 408 is connected to the discharge shaft 405 through the support frame 410. When the discharge shaft 405 rotates, the support frame 410 can rotate with the discharge shaft 405. The provision of the support frame 410 can reduce the force on the end of the discharge arm 406.

[0095] The receiving drive mechanism includes a receiving drive cylinder 412, and the piston rod of the receiving drive cylinder 412 is connected to the receiving shaft 402 through a receiving connecting rod.

[0096] The discharge drive mechanism includes a discharge drive cylinder 413, which is connected to the discharge shaft 405 via a discharge connecting rod. The stop shaft drive mechanism includes a stop shaft drive cylinder 414, the cylinder body of which is mounted on the support frame 410, and the piston rod of which is connected to the receiving stop shaft 408 via a stop shaft connecting rod.

[0097] To meet the production capacity requirements of copper tube gear rolling and to efficiently utilize factory space, the automated copper tube gear rolling production line will rationally arrange multiple gear rolling mills 500. A possible layout is as follows: One feeding line, with 32 gear rolling mills 500 symmetrically arranged on both sides. Each side of the feeding line has 16 gear rolling mills 500, arranged in two staggered rows, with eight mills in the closer row and eight in the farther row. The gear rolling mills 500 on both sides are symmetrically arranged along the center line of the feeding line. The feeding end of the feeding line has a longitudinal conveying mechanism, with a feeder installed laterally corresponding to the longitudinal conveying mechanism. The material assembly 100, the post-processing module 502 of the staggered gear rolling mill 500, and the pre-processing module 501 of the adjacent gear rolling mill 500 are horizontally aligned, shortening the length and width of the copper tube gear rolling automated production line. The layout of the gear rolling mill 500 is more compact, with a smaller footprint and higher workshop utilization, solving the problem of the large footprint of the gear rolling mill 500. The gear rolling mill 500 only requires one floor of the workshop for layout, making the equipment and personnel in the workshop safer. Moreover, the gear rolling mills 500 do not affect each other, the cycle adjustment is more flexible, and they can be rotated for maintenance, reducing losses caused by equipment damage and downtime.

[0098] Considering the relatively soft nature of copper tubes, to avoid squeezing them during storage and affecting their quality, a zoned, small-batch storage method is adopted. This involves setting multiple conveying attachments 103 on the feeding and conveying mechanism, with each attachment forming a storage area capable of storing copper tubes. For example, each storage area can store 20 tubes. This ensures both the supply of copper tubes and their quality. Under the action of the feeding and conveying mechanism, the lifting and distributing mechanism, and the feeding buffer mechanism, a single copper tube can be moved to the longitudinal conveying mechanism. The longitudinal conveying mechanism then transports the copper tubes longitudinally to the feeding conveying mechanism 200. When one of the gear mills 500 experiences a shortage of material, the copper tubes are transported longitudinally by the feeding conveying rollers 202 of the feeding conveying mechanism 200. When the copper tube is conveyed to its designated position by the feeding action, that is, when it reaches the lateral position corresponding to the material-deficient gear rolling mill 500, the feeding conveying roller 202 stops conveying. Under the action of the feeding lifting assembly, the feeding lifting plate 207 lifts the copper tube upwards. The feeding lifting plate 207 is higher on the inside and lower on the outside, and under the action of the discharge guide plate 205 on the corresponding side, the copper tube is guided smoothly to the lateral conveying arm 204 on the corresponding side. The lateral conveying arm 204 then transports the copper tube laterally to the feeding section of the post-processing module 502 of the gear rolling mill 500. If the gear rolling mill 500 is a remote gear rolling mill, a feeding transition mechanism 300 can be added to extend the lateral conveying of the copper tube. The copper tube conveyed from the lateral conveying arm 204 first enters the feeding transition mechanism 300. The copper tube is then laterally conveyed by the transition conveyor arm 303 to the loading section of the post-processing module 502 of the gear rolling mill 500, which is experiencing a material shortage. The loading transition mechanism 300 also has a deceleration baffle 306, which can be raised to block and slow down the copper tube, preventing it from impacting the loading section of the gear rolling mill 500. After entering the loading section of the post-processing module 502 of the gear rolling mill 500, the copper tube can proceed to the processing stage of the gear rolling mill 500 until it passes through the discharge side of the post-processing module 502. The copper tube can then directly enter the unloading line 600. Some copper tubes, after passing through the gear rolling mill, will first enter the dilution tank on the discharge side of the post-processing module 502 of the gear rolling mill 500. After cleaning, the copper tubes will have liquids such as water and cutting fluid on their surface. Therefore, the cleaned copper tubes can be conveyed laterally into the receiving mechanism 400. After the receiving mechanism 400 receives the copper tubes, the liquid on the copper tubes can drip onto the liquid receiving tray 404 and the liquid discharge tray 407 during the lateral conveying process. The receiving baffle shaft 408 can block the copper tubes, reduce the impact on the copper tubes, and also allow the copper tubes to stay on the receiving mechanism 400. The liquid stains on the surface of the copper tubes drip onto the liquid discharge tray 407. The liquid dripping onto the liquid receiving tray 404 and the liquid discharge tray 407 can be discharged and centrally treated through the tray outlet 411. The copper tubes can then enter the subsequent unloading line 600 through the discharge arm 406, further ensuring the dryness and cleanliness of the workshop environment.This automated copper tube gear rolling production line has a high degree of automation, reducing manual intervention and meeting the material supply needs of multiple 500 gear rolling mills. It improves the operating efficiency of the automated copper tube gear rolling production line. The multiple 500 gear rolling mills are arranged in a reasonable and compact manner, which can make efficient use of factory space and meet the production capacity requirements of copper tube gear rolling, providing strong support for the company's large-scale production.
