Description

Technical Field

[0001] The invention belongs to the technical field of pipe processing and production, and specifically relates to a full-automatic high-frequency pipe production line and an operation method thereof. Background Art

[0002] The pipes produced by the high-frequency pipe production line need to be manually polished on the unloading platform and then manually packaged. The packaged pipes are lifted by a crane to the punching and sawing platform. Workers then unpack the pipes and manually turn them onto a conveyor rack equipped with roller wheels. In order to improve processing efficiency, workers will stack several pipes and then saw and punch them at one time.

[0003] At present, the transportation of pipes in the entire production process relies on manual handling by workers. Not only is the labor intensity high, a large number of workers are required, and the transportation efficiency is low, but there is also the risk of pipes falling and injuring workers and equipment during transportation.

A plurality of pipes are neatly arranged by means of the material unloading station and transferred to the sawing station along the sawing conveying roller for sawing. The sawed pipes are transferred to the punching station along the punching conveying roller for punching.

[0007] The material turning device includes a material turning telescopic cylinder and a connecting shaft, the connecting shaft is hinged to the frame, a plurality of groups of spaced-apart shifting rods are arranged on the connecting shaft, the shifting rods are located between the conveying rollers of the loading conveying roller, the end of the connecting shaft is hingedly connected to the material turning telescopic cylinder by means of a rocker, the connecting shaft and the shifting rod rotate together with the rocker and form an inclination, and the pipe on the shifting rod moves to the material unifying station along the inclined surface formed by the shifting rod.

[0008] The material-forming station comprises a material-forming trough, a material-forming conveyor belt, and a rotating telescopic cylinder. The bottom of the material-forming trough is hinged to the frame. The bottom of the material-forming trough is also hinged to the rotating telescopic cylinder and has the freedom to swing in the vertical and horizontal directions. The pipe falls into the material-forming trough in the vertical direction with the help of a material turning device. When the material-forming trough is in the horizontal direction, the pipe contacts the material-forming conveyor belt and is transmitted out of the material-forming trough with the help of the material-forming conveyor belt.

[0009] The material trough is a U-shaped groove structure, and the two sides of the material trough along the length direction of the pipe are open. The material trough is located in the gap between the belt bodies on both sides of the material conveyor belt. When the material trough is horizontal, the pipe is exposed at both ends of the material trough and contacts the material conveyor belt.

[0010] The material-forming station is also provided with a buffer mechanism, which includes a floating plate located in the material-forming trough and multiple groups of counterweight rings located on a fixed rod, the fixed rod is located outside the material-forming trough, the counterweight ring has the freedom to slide along the fixed rod, multiple groups of retaining rings are arranged between adjacent counterweight rings, the retaining rings are sleeved on the fixed rod and fixedly connected with the fixed rod, the retaining rings prevent the upper-level counterweight ring from sliding downward, the diameters of the multiple groups of retaining rings increase from top to bottom, the inner diameters of the multiple groups of counterweight rings increase from top to bottom, the lower-level counterweight ring has the freedom to slide through the upper retaining ring and abut against the upper-level counterweight ring, the floating plate is connected to the bottom-level counterweight ring by a connecting rope, and the weight of a single counterweight ring is the same as that of a single pipe.

[0011] The limiting grooves are symmetrically arranged on both sides of the monolithic trough, and sliding blocks matching the limiting grooves are arranged on both sides of the floating plate. The floating plate forms a limit with the help of the sliding blocks and has the freedom to slide up and down along the limiting grooves.

[0012] A sliding groove is arranged on the fixed rod, and the retaining ring is a C-shaped ring structure. The opening of the retaining ring is located in the same straight line as the sliding groove and forms a limiting channel. The inner ring of the counterweight ring is provided with a limiting block matching the limiting channel. With the help of the limiting block, the counterweight ring has the freedom to slide along the limiting channel.

[0013] The feeding conveying roller is also provided with a baffle, which has the freedom of lifting and lowering by means of a lifting and telescopic cylinder. The pipe abuts against the baffle to stop moving forward and is transferred to the material sorting station by means of a material turning device.

[0014] An operating method of a fully automatic high-frequency pipe production line comprises the following steps:

[0015] S1. The pipe to be trimmed is transferred from the unloading platform to the loading conveyor roller, and is transferred to the upper-level punching unit along the loading conveyor track. The baffle at the upper-level punching unit is lowered, and the pipe to be trimmed stops moving forward with the help of the baffle. The pipe to be trimmed is transferred to the upper-level trimming trough with the help of the turning device;

[0016] S2, repeat step S1 until the pipes to be processed fill the previous processing tank;

[0017] S311, start the rotating telescopic cylinder to push the upper-level material trough to rotate and form a horizontal state, and the pipes in the upper-level material trough contact with the upper-level material conveyor belt and move along the upper-level material conveyor belt;

[0019] S313, the sawn pipe is conveyed to the punching station of the previous level by means of the punching conveying roller of the previous level for punching;

[0020] S321: While step S311 is being performed, the baffle plate at the upper punching unit is raised, and the baffle plate at the lower punching unit is lowered, and the pipe to be trimmed stops moving forward with the help of the baffle plate at the lower punching unit, and the pipe to be trimmed is trimmed, sawed and punched at the lower punching unit;

[0021] S4, after the tube processing of the previous punching unit is completed and the tube processing of the next punching unit is completed, the baffle at the next punching unit is raised again, and the baffle at the previous punching unit is lowered, and steps S1-S3 are repeated.

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention is provided with multiple groups of rollers and turning devices for transferring pipes. The pipes are automatically transported to the input ends of different punching units by the feeding conveying rollers, and then automatically turned by the turning device. The pipes are transferred from the feeding conveying rollers to the material-forming station.

DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0036] Specific embodiments, such as Figure 1-8 The present invention provides a fully automatic high-frequency pipe production line, comprising a frame 1 and a material unloading platform 2, a material loading conveying roller 3 and a plurality of punching units arranged on the frame 1. The pipes on the material unloading platform 2 are conveyed to the input end of the punching unit by means of the material loading conveying roller 3. The punching unit comprises a material unloading station, a sawing station 4 and a punching station 5. The material unloading station is the input end of the punching unit. The punching unit further comprises a sawing conveying roller 6, a punching conveying roller 7 and a material turning device. The pipes on the material loading conveying roller 3 are transferred to the material unloading station by means of the material turning device. Multiple pipes are neatly arranged by means of the material unloading station and transferred to the sawing station 4 along the sawing conveying roller 6 for sawing. The sawed pipes are transferred to the punching station 5 along the punching conveying roller 7 for punching.

[0037] At present, the transportation of pipes in high-frequency pipe production lines is mostly done manually, which not only has high labor intensity and requires a large number of workers, but also has low transportation efficiency. In addition, there is a risk of pipes falling and injuring workers and equipment during transportation.

[0038] Therefore, the present invention is provided with a plurality of rollers and a turning device for transferring pipes. The pipes are automatically transported to the input ends of different punching units by the feeding conveying roller 3, and then automatically turned by the turning device. The pipes are transferred from the feeding conveying roller 3 to the material sorting station. After being sorted at the material sorting station, the pipes are transported to the sawing station 4 for sawing by the sawing conveying roller 6. The sawed pipes are pushed to the punching conveying roller 7 by the cylinder, and transported to the punching station 5 for punching. The whole production line is formed into a fully automatic production line, which reduces the labor intensity of workers, reduces the unpredictable risks in the original pipe transportation, and improves production efficiency.

[0039] like Figure 3-4 As shown, the material turning device includes a material turning telescopic cylinder 8 and a connecting shaft 9, the connecting shaft 9 is hinged with the frame 1, and a plurality of groups of spaced levers 10 are arranged on the connecting shaft 9, the lever 10 is located between the conveying rollers of the feeding conveyor roller 3, and the end of the connecting shaft 9 is hingedly connected with the material turning telescopic cylinder 8 by means of a seesaw 11, the connecting shaft 9 and the lever 10 rotate and tilt along with the seesaw 11, and the pipe on the lever 10 moves to the material finishing station along the inclined surface formed by the lever 10. In the present invention, the material turning telescopic cylinder 8 is used to push the seesaw 11 to make the seesaw 11 swing, thereby driving the connecting shaft 9 to rotate, so that the lever 10 on the link shaft swings and moves the pipe on the feeding conveyor roller 3 to roll to the material finishing station.

[0040] like Figure 3-6 As shown, the material sorting station includes a material sorting trough 12, a material sorting conveyor belt 13, and a rotating telescopic cylinder 14. The bottom of the material sorting trough 12 is hinged to the frame 1. The bottom of the material sorting trough 12 is also hinged to the rotating telescopic cylinder 14 and has the freedom to swing in the vertical direction and in the horizontal direction. The pipe falls into the material sorting trough 12 in the vertical direction with the help of a material turning device. When the material sorting trough 12 is in the horizontal direction, the pipe contacts the material sorting conveyor belt 13 and is transferred out of the material sorting trough 12 with the help of the material turning conveyor belt 13. The pipe in the present invention is a pipe with a square cross-section. The width of the material sorting trough 12 is slightly wider than the diagonal length of the cross-section of the pipe, so as to ensure that the pipe can roll into the sorting trough with the help of the material turning device. Under the action of the falling inertia and the deadweight of the pipe, one side of the pipe will inevitably be parallel to the floating plate 15, and multiple pipes are mutually attached. Under the restraining action of the material sorting trough 12, multiple pipes are located on the same vertical plane and stacked neatly.

[0041] like Figure 3-6As shown, the material trough 12 is a U-shaped groove structure, and the two sides of the material trough 12 along the length direction of the pipe are open. The material trough 12 is located in the gap between the belt bodies on both sides of the material conveyor belt 13. When the material trough 12 is in a horizontal direction, the pipes are exposed at both ends of the material trough 12 and contact the material conveyor belt 13. In the process of the material trough 12 swinging from a vertical state to a horizontal state, the two ends of the pipes located at the bottom layer in the material trough 12 will preferentially contact the belt bodies of the material conveyor belts 13 on both sides, and move forward under the drive of the material conveyor belt 13, and at the same time push the upper-level pipes in the material trough 12 to move forward, thereby ensuring that the multiple pipes in the material trough 12 remain in a close and neat state and move together along the material conveyor belt 13 and enter the sawing station 4.

[0042] like Figure 3-8 As shown, the material-forming station is also provided with a buffer mechanism, which includes a floating plate 15 located in the material-forming trough 12 and a plurality of groups of counterweight rings 17 located on a fixed rod 16, wherein the fixed rod 16 is located outside the material-forming trough 12, and the counterweight ring 17 has the freedom to slide along the fixed rod 16, and a plurality of groups of retaining rings 18 are arranged between adjacent counterweight rings 17, and the retaining rings 18 are sleeved on the fixed rod 16 and fixedly connected with the fixed rod 16, and the retaining rings 18 hinder the upper-level counterweight ring 17 from sliding downward, and the diameters of the plurality of groups of retaining rings 18 increase from top to bottom, and the inner diameters of the plurality of groups of counterweight rings 17 increase from top to bottom, and the lower-level counterweight ring 17 has the freedom to slide through the upper retaining ring 18 and abut against the upper-level counterweight ring 17, and the floating plate 15 is connected to the bottom-level counterweight ring 17 by means of a connecting rope 19, and the weight of a single counterweight ring 17 is the same as that of a single pipe. In the present invention, the upper surface of the floating plate 15 is connected to the upper surface of the bottom counterweight ring 17, and a fixed pulley is provided between the floating plate 15 and the counterweight ring 17. The fixed pulley is located above the floating plate 15 and the counterweight ring 17 and connected to the side wall of the sorting tank.

[0043] When the pipe rolls down to the monolithic tank 12, since the pipe has a certain initial speed, in order to avoid collision between the pipe and the bottom of the monolithic tank 12, a buffer mechanism is also provided in the present invention.

[0044] When in the initial state, there is no pipe in the monolithic tank 12. Since the weight of the floating plate 15 is less than the weight of a single counterweight ring 17, the floating plate 15 is located at the opening of the monolithic tank 12 under the pulling action of the counterweight ring 17.

[0045] When a pipe falls onto the floating plate 15, the weight of the pipe + the floating plate 15 is greater than the weight of a counterweight ring 17, so the pipe and the floating plate 15 descend, and the counterweight ring 17 rises under the pull of the pipe and the floating plate 15 and passes through the retaining ring 18 to abut against the next-level counterweight ring 17. At this time, the weight of the pipe + the floating plate 15 is less than the weight of the two weight rings, and the floating plate 15 and the pipe stop moving downward. At this time, the upper surface of the pipe is located at the opening of the monolithic tank 12;

[0046] When the N pipes on the floating plate 15 are removed, the counterweight ring 17 returns to its original position under the action of its own weight.

[0047] Through the working process of the above-mentioned floating plate 15, it can be ensured that there are always pipes or floating plates 15 at the opening of the monolithic trough 12, reducing the falling height between the next-level pipe and the landing point of the monolithic trough 12, and playing a buffering role in the collision between the pipe and the monolithic trough 12 or the pipe.

[0048] like Figure 5-8 As shown, the limiting grooves 20 are symmetrically arranged on both sides of the monolithic trough 12, and sliders 21 matching the limiting grooves 20 are arranged on both sides of the floating plate 15. The floating plate 15 is limited by the sliders 21 and has the freedom to slide up and down along the limiting grooves 20. In order to prevent the floating plate 15 from shaking or deflecting during the lifting process, the side walls of the floating plate 15 are further provided with sliders 21, and the floating plate 15 is limited by the sliders 21.

[0049] like Figure 5-8 As shown, the fixing rod 16 is provided with a slide groove, the retaining ring 18 is a C-shaped ring structure, the opening of the retaining ring 18 and the slide groove are located in the same straight line and form a limiting channel 22, and the inner ring of the counterweight ring 17 is provided with a limiting block 23 matching the limiting channel 22, and the counterweight ring 17 has the freedom to slide along the limiting channel 22 with the help of the limiting block 23. In order to ensure that the counterweight ring 17 does not deviate during the lifting process and passes through the retaining ring 18 smoothly, the present invention further provides a limiting channel 22 to limit the counterweight ring 17, so that the counterweight ring 17 always slides in the vertical direction along the limiting channel 22.

[0050] like Figure 1-2 As shown, the feeding conveyor roller 3 is also provided with a baffle 24, and the baffle 24 has the freedom of lifting and lowering by means of a lifting and telescopic cylinder 25. The pipe material abuts against the baffle 24 to stop moving forward and is transferred to the material-forming station by means of a material-turning device. The baffle 24 blocks the pipe material on the feeding conveyor roller 3, so that the pipe material is turned over by the material-turning device of the corresponding punching unit and is transferred to the material-forming station of the punching unit.

[0051] The present invention also provides an operating method of a fully automatic high-frequency pipe production line, comprising the following steps:

[0052] S1, the pipe to be trimmed is transferred along the unloading platform 2 to the loading conveyor roller 3, and is transferred along the loading conveyor track to the upper-level punching unit, and the baffle 24 at the upper-level punching unit is dropped, and the pipe to be trimmed stops moving forward with the help of the baffle 24, and the pipe to be trimmed is transferred to the upper-level trimming trough 12 with the help of the turning device;

[0053] S2, repeat step S1 until the previous level of the whole material tank 12 is filled with multiple pipes to be whole material;

[0054] S311, start the rotating telescopic cylinder 14 to push the upper-level material trough 12 to rotate and form a horizontal state, and the pipes in the upper-level material trough 12 contact the upper-level material conveyor belt 13 and move along the upper-level material conveyor belt 13;

[0055] S312, the pipe on the upper-level material conveyor belt 13 is conveyed to the upper-level sawing station 4 by means of the upper-level sawing conveyor roller 6 and sawn to the required length;

[0056] S313, the sawn pipe is conveyed to the previous punching station 5 for punching by means of the previous punching conveying roller 7;

[0057] S321, while step S311 is being performed, the baffle 24 at the upper-level punching unit is raised, and the baffle 24 at the lower-level punching unit is lowered, and the pipe to be trimmed stops moving forward with the aid of the baffle 24 at the lower-level punching unit, and the pipe to be trimmed is trimmed, sawed and punched at the lower-level punching unit;

[0058] S4, after the tube processing of the previous punching unit is completed and the tube processing of the next punching unit is completed, the baffle 24 at the next punching unit is raised again, and the baffle 24 at the previous punching unit is lowered, and steps S1-S3 are repeated.

[0059] Since it takes a certain amount of time for the pipe to be sawed and punched in the previous punching unit, the feeding conveyor roller 3 cannot transfer the new pipe to be processed to the previous punching unit during this period. In order to realize continuous production and processing, multiple groups of punching units are provided in the present invention. When the previous punching unit is sawing and punching, the baffle 24 of the previous punching unit is raised, and the baffle 24 of the next punching unit is lowered, so that the new pipe to be processed is transferred to the next punching unit, thereby ensuring that the multiple groups of punching units are always processing and producing, ensuring the continuity of production, and improving production efficiency.
