Description

Technical Field

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

[0002] In the field of refrigeration technology, it is common practice to process different tooth shapes on heat exchange tubes to increase the heat exchange area and enhance the heat exchange effect by increasing the disturbance to the medium during heat exchange. The equipment used to process the tooth shape on the heat exchange tube is a tooth rolling mill. The tooth rolling mill 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 mill and tooth rolling method. The pre-processing module is mainly responsible for conveying the mandrel to ensure that the mandrel can be inserted into the tube to be processed to support the toothed tube. The post-processing module is mainly responsible for feeding the tube to be processed and unloading the tube after tooth rolling.

[0003] Gear rolling mills use an automatic feeding section to feed pipe fittings. When the feeding section is short of fittings, it needs to supply more fittings for processing. Manual feeding is inefficient and physically demanding. Therefore, currently, overhead cranes supply fittings to the feeding mechanism from above the gear rolling mill. While this method of supplying fittings from above significantly improves feeding efficiency compared to manual feeding, matching the automated processing pace of the gear rolling mill, it also has drawbacks: Firstly, it requires a higher building height than standard to accommodate installation and operation, leading to higher construction costs. Secondly, fittings may detach during transport, posing a risk of injury to equipment and personnel below. These safety hazards not only affect production efficiency but may also cause additional economic losses for the company. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a transverse conveying device for pipe fittings.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: a pipe fitting transverse conveying device, including a pipe fitting conveying mechanism disposed on the feeding side of a gear rolling mill, the pipe fitting conveying mechanism including a conveying frame, a plurality of conveying rollers disposed on the conveying frame, a conveying roller driving mechanism for driving the conveying rollers to rotate, a transverse conveying mechanism disposed on one or both sides of the conveying frame, and a lifting mechanism for lifting the pipe fittings on the conveying rollers.

[0006] Multiple conveying rollers are longitudinally distributed on the conveying frame; the transverse conveying mechanism includes a conveying arm shaft, multiple transverse conveying arms disposed on the conveying arm shaft, and a rotation drive mechanism for driving the conveying arm shaft to rotate, wherein the conveying arm shaft is rotatably disposed on the conveying frame;

[0007] The conveyor frame is also provided with a guide mechanism for guiding the pipe fittings to the transverse conveyor arm. The guide mechanism includes multiple guide plates, which are arranged along the length of the conveyor frame. The bearing surface of the guide plates is inclined with the inner side higher than the outer side.

[0008] The beneficial effects of this invention are as follows: the pipe fittings to be processed can be longitudinally conveyed into position by the conveying rollers, and then laterally conveyed to the gear rolling mill by the transverse conveying mechanism. The guiding mechanism ensures the conveying path of the pipe fittings, and its inclined design (higher inside and lower outside) guides the pipe fittings to slide smoothly and steadily into the transverse conveying arm. The cooperation between the conveying rollers and the transverse conveying arm allows the pipe fittings to enter the processing area of ​​the corresponding gear rolling mill quickly and accurately, meeting the rhythm requirements of automated pipe fitting production. This transverse pipe fitting conveying device can effectively solve the problems existing in the aerial transport of pipe fittings in the prior art. Firstly, the overall layout of the device is compact, eliminating the need to adjust the workshop height, thereby reducing the cost of workshop construction and renovation. Secondly, the pipe fittings remain stable throughout the entire conveying process, avoiding the risk of falling and ensuring the safety of equipment and personnel. Thirdly, the pipe fitting conveying process is simple to operate, requiring no complex control by professional technicians, reducing labor costs and the possibility of operational errors. In addition, gear rolling mills can be arranged on one or both sides of this transverse pipe fitting conveying device, which can supply pipe fittings to a gear rolling mill on one side or convey pipe fittings to gear rolling mills on both sides. The pipe fitting transverse conveying device has a simple structure, occupies a small area, allows for a more compact layout of the gear rolling mill, and has a high workshop utilization rate.

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

[0010] Furthermore, it also includes a pipe fitting transition mechanism, which is disposed between the pipe fitting conveying mechanism and the gear rolling mill. The pipe fitting transition mechanism includes a transition frame, a transition conveying shaft rotatably disposed on the transition frame, a plurality of transition conveying arms disposed on the transition conveying shaft, and a transition shaft drive mechanism for driving the transition conveying shaft to rotate.

[0011] The beneficial effect of adopting the above-mentioned further solution is that for gear rolling mills that are far from the transverse conveying device of the pipe fitting, the pipe fitting cannot be transversely conveyed to the loading position of the gear rolling mill when the transverse conveying arm is extended. If the length of the transverse conveying arm is forcibly extended, there is a problem that the transverse conveying arm cannot stably support the pipe fitting. Therefore, a pipe fitting transition mechanism can be added. The pipe fitting that has passed through the transverse conveying arm can smoothly enter the transition conveying arm. Then, through the extension of the transition conveying arm, the pipe fitting can be smoothly supplied to the relatively far gear rolling mill. This allows the transverse conveying of pipe fittings to not only meet the pipe fitting needs of the nearby gear rolling mill, but also meet the pipe fitting needs of the relatively far gear rolling mill.

[0012] Furthermore, the pipe fitting transition mechanism also includes a deceleration conveying mechanism, 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 pipe fitting under the action of the deceleration drive mechanism.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the deceleration baffle can effectively control the speed of the pipe during the transition conveying process under the drive of the deceleration drive mechanism, avoid positional deviation or impact damage caused by the pipe moving too fast, and enable the pipe to be smoothly conveyed laterally to the feeding part of the gear rolling mill, thereby improving the stability of pipe conveying. The introduction of the deceleration conveying mechanism can automatically decelerate the pipe and reduce manual intervention.

[0014] Furthermore, it also includes a speed reducer, which is fixedly connected to the transition conveyor shaft, and the speed reducer shaft is rotatably connected to the speed reducer. The transition conveyor arm is provided with a shaft hole for the speed reducer shaft to pass through, and the speed reducer shaft is rotatably connected to the transition conveyor arm.

[0015] The beneficial effects of adopting the above-mentioned further solution are that when the reduction shaft rotates, the reduction baffle can block the pipe fitting, causing the pipe fitting to decelerate. The reduction frame can meet the rotation requirements of the reduction shaft on the one hand, and on the other hand, the conveying angle of the transition conveying arm needs to 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 pipe fitting transition mechanism, providing reliable support for the reduction shaft, and meeting the needs of pipe fitting transition conveying.

[0016] Furthermore, it also includes a pipe receiving mechanism installed on the discharge side of the gear rolling mill, the pipe receiving mechanism including a receiving frame, a receiving assembly installed on the receiving frame, and a discharge assembly;

[0017] 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.

[0018] 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.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the pipe fittings are cleaned by soaking them in the dilution tank of the gear rolling mill for a certain period of time. The pipe fittings coming out of the dilution tank will carry a certain amount of liquid. If they are directly sent to the unloading line in the workshop, the liquid will cause the liquid to spill around in the workshop. Therefore, a pipe fitting receiving mechanism is added to the discharge side of the gear rolling mill. After the pipe fittings are processed by the gear rolling mill, they are discharged into the receiving arm. The receiving arm can be adjusted in tilt under the action of the receiving drive mechanism, so that the pipe fittings can pass through the receiving arm smoothly 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 pipe fittings can pass through the pipe fitting receiving mechanism smoothly. There is a liquid receiving tray on the pipe fitting receiving mechanism. The liquid receiving tray can collect the dripping liquid and keep the workshop floor clean.

[0020] Furthermore, the pipe 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.

[0021] The beneficial effects of adopting the above-mentioned further solution are that the receiving baffle shaft can rotate under the action of the baffle shaft drive mechanism, and the receiving baffle block can rotate with the receiving baffle shaft, allowing the blocking position and angle to be adjusted according to actual needs. The receiving baffle assembly can block the pipes entering the pipe receiving mechanism, reducing the impact of the pipes on the unloading line. In addition, it can also make the liquid stains on the surface of the pipes drip onto the liquid receiving tray and liquid discharge tray for easy collection, thereby ensuring the dryness and cleanliness of the workshop floor.

[0022] Furthermore, the discharge shaft is also provided with a support frame, the other end of which is rotatably connected to the receiving stop shaft. The stop shaft driving mechanism is disposed on the support frame, and the driving end of the stop shaft driving mechanism is connected to the receiving stop shaft through the stop shaft connecting rod.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the receiving stop shaft is connected to the discharge shaft through the support frame. When the discharge shaft rotates, the support frame can rotate with the discharge shaft. The setting of the support frame can reduce the force on the end of the discharge arm.

[0024] Furthermore, the lifting mechanism includes a lifting beam, multiple lifting plates disposed on the lifting beam, and a lifting drive cylinder for driving the lifting beam to move up and down. The bearing surface of the lifting plate is inclined with the inner side higher than the outer side. The guide plate includes a vertical plate and an inclined plate. The vertical plate can limit the pipe fitting during the lifting process, and the inclined plate can guide the lifted pipe fitting to the transverse conveying arm.

[0025] The beneficial effect of adopting the above-mentioned further solution is that the lifting beam can move up and down under the action of the lifting drive cylinder, and multiple lifting plates move synchronously with the lifting beam, which can smoothly lift the pipe from a low position to a high position. During the process of the pipe rising, the vertical plate of the guide plate can limit the pipe until the lifting plate is raised to the point where the pipe can be smoothly moved to the transverse conveying arm through the inclined plate of the guide plate. The lifting mechanism lifts the pipe from the longitudinal conveying and puts it into the transverse conveying, thereby improving the conveying efficiency and reducing the risk of pipe slippage.

[0026] Furthermore, the conveying roller drive mechanism includes two transmission gears mounted on the roller shaft of the conveying roller, a drive motor mounted on the conveying frame, and a drive gear mounted on the output shaft of the drive motor. The drive gear is connected to one of the transmission gears of one of the conveying rollers via a drive chain, and adjacent conveying rollers are connected by a transmission chain.

[0027] The beneficial effect of adopting the above-mentioned further solution is that the drive motor can transmit power to one of the conveying rollers through the drive gear and drive chain. The adjacent conveying rollers can be driven to rotate through the cooperation of the transmission gear and transmission chain. The drive motor provides power, and through the transmission of the drive gear, transmission gear and transmission chain, the rotation of the conveying rollers is realized, thereby realizing the smooth operation of the longitudinal conveying of the pipe.

[0028] Furthermore, it also includes a pipe positioning mechanism, which is used to position the pipes longitudinally conveyed by the conveying roller. The pipe positioning mechanism includes a positioning plate and a positioning drive cylinder. The positioning drive cylinder is mounted on the conveying frame, and the positioning plate moves up and down under the action of the positioning drive cylinder.

[0029] The beneficial effect of adopting the above-mentioned further solution is that when the positioning drive cylinder is activated, the positioning plate can be raised and lowered, the pipe is longitudinally conveyed by the conveying roller, and the pipe positioning mechanism can limit the longitudinal position of the pipe. That is, when the piston rod of the positioning drive cylinder extends and the positioning plate rises, it can act on the end of the pipe conveyed by the conveying roller to block the pipe, so as to ensure that it corresponds to the feeding part of the gear mill of the required pipe, and ensure the stability and accuracy of the transverse conveying of the pipe.

Detailed Implementation

[0052] The principles and features of the present invention are described below with reference to examples. The examples are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0053] Example 1

[0054] like Figures 1-8 As shown, a pipe fitting transverse conveying device includes a pipe fitting conveying mechanism 100 disposed on the feeding side of a gear rolling mill 500. The pipe fitting conveying mechanism 100 includes a conveying frame 101, a plurality of conveying rollers 102 disposed on the conveying frame 101, a conveying roller drive mechanism for driving the conveying rollers 102 to rotate, a transverse conveying mechanism disposed on one or both sides of the conveying frame 101, and a lifting mechanism for lifting the pipe fittings 400 on the conveying rollers 102.

[0055] The plurality of conveying rollers 102 are longitudinally distributed on the conveying frame 101; the transverse conveying mechanism includes a conveying arm shaft 103, a plurality of transverse conveying arms 104 disposed on the conveying arm shaft 103, and a rotation drive mechanism for driving the conveying arm shaft 103 to rotate, wherein the conveying arm shaft 103 is rotatably disposed on the conveying frame 101;

[0056] The conveyor frame 101 is also provided with a guide mechanism for guiding the pipe 400 to the transverse conveyor arm 104. The guide mechanism includes a plurality of guide plates 105, which are arranged along the length of the conveyor frame 101. The bearing surface of the guide plate 105 is inclined with the inner side higher than the outer side.

[0057] Under the action of the rotation drive mechanism, the conveying arm shaft 103 can rotate, and the transverse conveying arm 104 can be unfolded to supply tube material to the gear rolling mill 500. When no material is needed, the conveying arm shaft 103 rotates, and the transverse conveying arm 104 can be retracted, making it convenient for operators to inspect and maintain the equipment.

[0058] The lifting mechanism includes a lifting beam 106, a plurality of lifting plates 107 disposed on the lifting beam 106, and a lifting drive cylinder 108 for driving the lifting beam 106 to move up and down. The bearing surface of the lifting plate 107 is inclined with the inner side higher than the outer side. The guide plate 105 includes a vertical plate and an inclined plate. The vertical plate can limit the pipe 400 during the lifting process, and the inclined plate can guide the lifted pipe 400 to the transverse conveying arm 104. The lifting beam 106 can move up and down under the action of the lifting drive cylinder 108. Multiple lifting plates 107 move synchronously with the lifting beam 106, which can smoothly lift the pipe 400 from a low position to a high position. During the rising process of the pipe 400, the vertical plate of the guide plate 105 can limit the pipe 400 until the lifting plate 107 is raised to the point where the pipe 400 can be smoothly moved to the transverse conveying arm 104 through the inclined plate of the guide plate 105. The lifting mechanism lifts the pipe 400 that is transported longitudinally and puts it into the transverse conveying, thereby improving the conveying efficiency and reducing the risk of the pipe 400 slipping.

[0059] The conveyor roller drive mechanism includes two transmission gears 109 mounted on the roller shaft of the conveyor roller 102, a drive motor 110 mounted on the conveyor frame 101, and a drive gear mounted on the output shaft of the drive motor 110. The drive gear is connected to one of the transmission gears 109 of one of the conveyor rollers 102 via a drive chain, and adjacent conveyor rollers 102 are connected by a drive chain. When the drive motor 110 operates, it transmits power to one of the conveyor rollers 102 through the drive gear and drive chain. The adjacent conveyor rollers 102 can be driven to rotate through the cooperation of the transmission gears 109 and the drive chain. The drive motor 110 provides power, which, through the transmission of the drive gear, transmission gear 109, and drive chain, realizes the rotation of the conveyor rollers 102, thereby achieving smooth longitudinal conveying of the pipe fitting 400.

[0060] It also includes a pipe positioning mechanism, which is used to position the pipe 400 longitudinally conveyed by the conveying roller 102. The pipe positioning mechanism includes a positioning plate 112 and a positioning drive cylinder 113. The positioning drive cylinder 113 is mounted on the conveying frame 101. The positioning plate 112 moves up and down under the action of the positioning drive cylinder 113. When the positioning drive cylinder 113 is activated, the positioning plate 112 can rise and fall. The pipe 400 is longitudinally conveyed by the conveying roller 102. The pipe positioning mechanism can limit the longitudinal position of the pipe 400. That is, when the piston rod of the positioning drive cylinder 113 extends, the positioning plate 112 rises and can act on the end of the pipe 400 conveyed by the conveying roller 102 to block the pipe 400, so as to ensure that it corresponds to the loading part 501 of the gear mill 500 that requires the pipe 400, and to ensure the stability and accuracy of the transverse conveying of the pipe 400.

[0061] The rotation drive mechanism includes a rotation drive cylinder 111, the cylinder body of which is hinged to the conveyor frame 101. The piston rod of the rotation drive cylinder 111 is connected to the conveyor arm shaft 103 via a connecting arm. One end of the connecting arm is connected to the conveyor arm shaft 103, and the other end is hinged to the rotation drive cylinder 111.

[0062] The transverse conveying mechanism also includes a transverse extension arm 114, which is connected to the transverse conveying arm 104. This increases the support strength of the transverse conveying arm 104 and extends its length.

[0063] The conveying roller 102 has a V-shaped roller structure. The conveying of the pipe 400 on the conveying roller 102 is more stable and reliable.

[0064] Example 2

[0065] like Figures 9-14As shown, based on Embodiment 1, a pipe fitting transition mechanism 200 is also included. The pipe fitting transition mechanism 200 is disposed between the pipe fitting conveying mechanism 100 and the gear rolling mill 500. The pipe fitting transition mechanism 200 includes a transition frame 201, a transition conveying shaft 202 rotatably disposed on the transition frame 201, a plurality of transition conveying arms 203 disposed on the transition conveying shaft 202, and a transition shaft drive mechanism for driving the transition conveying shaft 202 to rotate. For the gear mill 500 which is far from the transverse conveying device for the pipe fitting, the extended transverse conveying arm 104 cannot transversely convey the pipe fitting 400 to the feeding position of the gear mill 500. If the length of the transverse conveying arm 104 is forcibly extended, there is a problem that the transverse conveying arm 104 cannot stably support the pipe fitting 400. Therefore, a pipe fitting transition mechanism 200 can be added. The pipe fitting 400 passing through the transverse conveying arm 104 can smoothly enter the transition conveying arm 203. Then, through the extension of the transition conveying arm 203, the pipe fitting 400 can be smoothly supplied to the relatively far gear mill 500. This allows the transverse conveying of the pipe fitting 400 to not only meet the needs of the nearby gear mill 500, but also meet the needs of the relatively far gear mill 500.

[0066] The transition shaft drive mechanism includes a transition drive cylinder 204. The transition drive cylinder 204 is mounted on the transition frame 201, and the piston rod of the transition drive cylinder 204 is connected to the transition conveying shaft 202 via a transition connecting rod.

[0067] The pipe fitting transition mechanism 200 also includes a deceleration conveying mechanism. This mechanism includes a deceleration shaft 205 rotatably mounted on the transition frame 201, multiple deceleration baffles 206 mounted on the deceleration shaft 205, and a deceleration drive mechanism for driving the deceleration shaft 205 to rotate. The deceleration baffles 206, under the action of the deceleration drive mechanism, can block the pipe fitting 400. Driven by the deceleration drive mechanism, the deceleration baffles 206 can effectively control the speed of the pipe fitting 400 during the transition conveying process, preventing positional deviation or impact damage caused by excessively fast movement of the pipe fitting 400. This allows the pipe fitting 400 to be smoothly conveyed laterally to the loading section 501 of the gear rolling mill 500, improving the stability of the pipe fitting 400 conveying. The introduction of the deceleration conveying mechanism can automatically decelerate the pipe fitting 400, reducing manual intervention.

[0068] The deceleration drive mechanism includes a deceleration drive cylinder 207, and the piston rod of the deceleration drive cylinder 207 is connected to the deceleration shaft 205 through a deceleration connecting rod.

[0069] It also includes a speed reducer 208, which is fixedly connected to the transition conveyor shaft 202. The speed reducer shaft 205 is rotatably connected to the speed reducer 208. The transition conveyor arm 203 has a shaft hole for the speed reducer shaft 205 to pass through, and the speed reducer shaft 205 is rotatably connected to the transition conveyor arm 203. The speed reduction drive cylinder 207 is mounted on the speed reducer 208. When the reduction drive cylinder 207 is working, it drives the reduction shaft 205 to rotate around its own axis, thereby driving the reduction baffle 206 to rotate and adjust its angle. The reduction baffle 206 can block the pipe 400, causing the pipe 400 to decelerate. The reduction frame 208 can meet the rotation requirements of the reduction shaft 205 on the one hand, and the conveying angle of the transition conveying arm 203 needs to be adjusted on the other hand. Specifically, it is adjusted by the rotation of the transition conveying shaft 202. The reduction frame 208 connects the reduction shaft 205 and the transition conveying shaft 202 as a whole. In this way, when the transition conveying shaft 202 rotates, not only can the tilt angle of the transition conveying arm 203 be adjusted, but the reduction frame 208 and the reduction shaft 205 also rotate together with the transition conveying arm 203, which enhances the structural stability of the pipe transition mechanism 200, provides reliable support for the reduction shaft 205, and can also meet the transition conveying requirements of the pipe 400.

[0070] Example 3

[0071] like Figures 15-21 As shown, based on Embodiment 1, the feed side of the gear rolling mill 500 only includes the pipe conveying mechanism 100, and also includes a pipe receiving mechanism 300 disposed on the discharge side of the gear rolling mill 500. The pipe receiving mechanism 300 includes a receiving frame 301, a receiving component disposed on the receiving frame 301, and a discharge component.

[0072] The receiving assembly includes a receiving shaft 302 rotatably mounted on the receiving frame 301, a plurality of receiving arms 303 mounted on the receiving shaft 302, a liquid receiving tray 304 disposed between the receiving arms 303, and a receiving drive mechanism for driving the receiving shaft 302 to rotate.

[0073] The discharge assembly includes a discharge shaft 305 rotatably mounted on the receiving frame 301, a plurality of discharge arms 306 mounted on the discharge shaft 305, a liquid discharge plate 307 disposed between the discharge arms 306, and a discharge drive mechanism for driving the discharge shaft 305 to rotate. The liquid discharge plate 307 is located below the liquid receiving plate 304.

[0074] After being processed by the gear rolling mill 500, the pipe fitting 400 is first immersed in the dilution tank 502 of the gear rolling mill 500 for a certain period of time to clean it. If a post-processing cleaning device is disclosed in Chinese invention patent CN116197186B, the pipe fitting 400 exiting the dilution tank 502 of the post-processing cleaning device will contain a certain amount of liquid, such as water or cutting fluid. If this liquid is directly transported to the unloading line 600 in the workshop, it will cause the liquid to flow everywhere in the workshop. Therefore, a cleaning device is added to the discharge side of the gear rolling mill 500. A pipe fitting receiving mechanism 300 is provided. After being processed by the gear rolling mill 500, the pipe fitting 400 exits into the receiving arm 303. The receiving arm 303, under the action of the receiving drive mechanism, can be adjusted in tilt to allow the pipe fitting 400 to pass smoothly through the receiving arm 303 and move to the discharge arm 306. The discharge arm 306, under the action of the discharge drive mechanism, can also adjust its tilt angle to allow the pipe fitting 400 to pass smoothly through the pipe fitting receiving mechanism 300. The pipe fitting receiving mechanism 300 has a liquid receiving tray 304 and a liquid discharge tray 307 to collect dripping liquid, keeping the workshop floor clean. Figure 15 and Figure 17 The structure of part of the liquid outlet tray 307 and liquid receiving tray 304 on the receiving rack 301 is shown.

[0075] The pipe fitting receiving mechanism 300 also includes a receiving blocking assembly, which includes a receiving blocking shaft 308, multiple receiving blocking blocks 309 disposed on the receiving blocking shaft 308, and a blocking shaft drive mechanism for driving the receiving blocking shaft 308 to rotate. The receiving blocking shaft 308 is rotatably disposed at the discharge end of the discharge arm 306. The receiving blocking shaft 308 can rotate under the action of the blocking shaft drive mechanism, and the receiving blocking blocks 309 can rotate with the receiving blocking shaft 308, allowing adjustment of the blocking position and angle according to actual needs. The receiving blocking assembly can block the pipe fittings 400 entering the pipe fitting receiving mechanism 300, reducing the impact of the pipe fittings 400 on the discharge line 600. Additionally, it allows liquid on the surface of the pipe fittings 400 to drip onto the liquid receiving tray 304 and the liquid discharge tray 307 for easy collection, thereby ensuring the dryness and cleanliness of the workshop floor.

[0076] The discharge shaft 305 is also provided with a support frame 310. The other end of the support frame 310 is rotatably connected to the receiving stop shaft 308. The stop shaft driving mechanism is disposed on the support frame 310, and the driving end of the stop shaft driving mechanism is connected to the receiving stop shaft 308 through the stop shaft connecting rod. The receiving stop shaft 308 is connected to the discharge shaft 305 through the support frame 310. When the discharge shaft 305 rotates, the support frame 310 can rotate with the discharge shaft 305. The provision of the support frame 310 can reduce the force on the end of the discharge arm 306.

[0077] The receiving drive mechanism includes a receiving drive cylinder 312, and the piston rod of the receiving drive cylinder 312 is connected to the receiving shaft 302 through a receiving connecting rod.

[0078] The discharge drive mechanism includes a discharge drive cylinder 313, which is connected to the discharge shaft 305 via a discharge connecting rod.

[0079] The stop shaft drive mechanism includes a stop shaft drive cylinder 314. The cylinder body of the stop shaft drive cylinder 314 is mounted on the support frame 310. The piston rod of the stop shaft drive cylinder 314 is connected to the receiving stop shaft 308 through a stop shaft connecting rod.

[0080] The liquid discharge tray 307 has a material tray outlet 311 on its discharge side. Liquid can be discharged and collected centrally through the material tray outlet 311, which will not pollute the workshop environment and keep the workshop floor dry and clean.

[0081] Example 4

[0082] Based on Embodiment 2, a pipe fitting transition mechanism 200 is provided between the pipe fitting conveying mechanism 100 and the gear rolling mill 500. The pipe fitting 400 can enter the transition conveying arm 203 through the transverse conveying arm 104. The extension of the transition conveying arm 203 allows the pipe fitting 400 to be smoothly supplied to the relatively distant gear rolling mill 500. The feed side of the gear rolling mill 500 has the pipe fitting conveying mechanism 100 and the pipe fitting transition mechanism 200, and also includes a pipe fitting receiving mechanism 300 provided on the discharge side of the gear rolling mill 500. The specific structure of the pipe fitting receiving mechanism 300 is the same as that of the pipe fitting receiving mechanism 300 in Embodiment 3, and will not be described again here.

[0083] During operation, a toothed mill 500 can be installed on one side of the transverse conveying device for pipe fittings, or on both sides. The pipe fitting 400 can be transversely conveyed to the toothed mill 500 that is closer in distance via the pipe fitting conveying mechanism 100, or it can be transversely conveyed to the toothed mill 500 that is further apart via the cooperation of the pipe fitting conveying mechanism 100 and the pipe fitting transition mechanism 200. The pipe fitting 400 is conveyed to the transverse conveying mechanism by the conveying roller 102. After the pipe fitting 400 is in place, it is lifted... Under the action of the mechanism, the lifting plate 107 lifts the pipe fitting 400 upwards, and the guide plate 105 guides the pipe fitting 400, allowing it to move smoothly onto the transverse conveying arm 104. The transverse conveying arm 104 then transports the pipe fitting 400 laterally to the loading section 501 of the gear rolling mill 500. If the gear rolling mill 500 is relatively far away, the pipe fitting 400 also needs to pass through the pipe fitting transition mechanism 200. That is, the pipe fitting 400 transported from the transverse conveying arm 104 enters the transition conveying arm 203, where it is then transported by the transition conveying arm 203. The pipe fitting 400 is conveyed to the feeding section 501 of the gear rolling mill 500. The pipe fitting transition mechanism 200 has a deceleration baffle 206, which slows down the pipe fitting 400 to prevent it from impacting the gear rolling mill 500. After entering the feeding section 501, the pipe fitting 400 can enter the gear rolling mill 500 for processing. The pipe fitting 400 exits through the dilution tank 502 of the gear rolling mill 500 and then enters the pipe fitting receiving mechanism 300. Upon reaching the pipe fitting 400, the liquid on the pipe fitting 400 can drip onto the receiving tray 304 and the discharge tray 307 during the lateral conveying process. The receiving block 309 can block the pipe fitting 400, allowing it to remain on the discharge arm 306, ensuring that the liquid stains on the surface of the pipe fitting 400 can completely drip onto the discharge tray 307. The liquid dripping onto the receiving tray 304 and the discharge tray 307 can be discharged and centrally processed through the tray outlet 311. The pipe fitting 400 can then enter the subsequent unloading line 600 in the workshop through the discharge arm 306. The lateral conveying device for pipe fittings can be arranged on one or both sides of the device. The lateral conveying device for pipe fittings can provide the unprocessed pipe fittings 400 to the gear rolling machine 500 and laterally convey the processed pipe fittings 400 to the unloading line 600. The overall structure is simple, occupies a small area, and the layout of the gear rolling machine 500 can be more compact, improving the utilization rate of the workshop.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
