Description

Technical Field

[0001] The present invention relates to the technical field of ton barrel frame processing equipment, in particular to an automatic long tube conveying and embossing device. Background Art

[0002] Ton-barrel frames are used to support and secure ton-barrel structures. They consist of a chassis and a frame. The frame is welded from steel pipes, while the chassis is made of galvanized steel sheet with rounded corners. The frame protects the ton-barrel from damage due to external impacts, so it requires high structural strength. Currently, frames are primarily categorized as circular tubular frames, made from round steel pipes, and square tubular frames, made from square steel pipes.

[0003] Before welding the long and short tubes of the circular tube frame, the welding parts of the long and short tubes need to be embossed first, that is, the welding parts of the long and short tubes are pressed inward to a certain depth so that the position is pressed into a flat structure, and then the long and short tubes are arranged into a set crisscross shape. At this time, the embossed part of the long tube and the embossed part of the short tube are aligned, and finally the embossed part of the long tube and the embossed part of the short tube are welded together.

[0004] However, the following problems exist in the transportation and embossing process of long tubes: 1. The long tubes are relatively long, and how to synchronously coordinate and efficiently transport the long tubes is a technical problem that needs to be solved; 2. Since the embossed part of the long tube needs to be arranged upward at the arrangement station, and the embossed part of the short tube needs to be set downward and the embossed part of the short tube needs to be aligned and fitted with the embossed part of the long tube, and the embossed part of the long tube after embossing by the embossing device is set downward, how to realize the automated transportation and transfer of the long tube and the flipping of the long tube after embossing is also a technical problem that needs to be solved.

The storage cavity 12 is used to store the long tubes. The storage cavity 12 is arranged in a V shape. The lower wall of the storage cavity 12 is provided with a guide portion arranged along the discharge direction of the storage cavity 12. The lifting component is a chain-type lifting structure. The lifting assembly 13 is used to lift the long tube at the discharge port at the lower end of the storage chamber 12 to the feed port position of the blanking track 14. The blanking track 14 has a track groove that limits the moving trajectory of the long tube. The blanking track 14 has a blanking port at the lower end of the track groove corresponding to the track groove. The long tube arranged in the track groove is discharged through the blanking port at the lower end of the track groove under the action of its own gravity.

[0043] The material receiving mechanism 20 includes a material receiving rack 21 and a driving member A that drives the material receiving rack 21 to move. The material receiving rack 21 is used to receive the long tube output from the blanking port of the loading mechanism 10. Specifically, the material receiving mechanism 20 is provided with a first connecting rack 22. The material receiving rack 21 is provided with multiple groups and is longitudinally installed on the first connecting rack 22. The driving member A drives the first connecting rack 22 to move laterally to drive multiple groups of material receiving racks 21 to move laterally synchronously. The right side of the material receiving rack 21 is provided with multiple placement openings arranged laterally at intervals. The upper end surface of the material receiving rack 21 can stop the long tube in the track groove from passing through the blanking port. The left side of the material receiving rack 21 is provided with a stop portion so that when the material receiving rack 21 moves to the right, the long tube at the blanking port is stopped by the stop portion.

[0044] The embossing mechanism 30 includes a lower die base 31, an upper die base cooperating with the lower film base, a pressure block that can be raised and lowered at the lower end of the lower die base 31, and a press that drives the pressure block to rise and fall. The upper die base can be raised and lowered so that the lower die base 31 and the upper die base cooperate to form a mold cavity. The lower die base 31 is provided with an avoidance channel 311 for the pressure block to extend into the mold cavity. Under the action of the press, the pressure block can extend into the mold cavity to flatten the long tube. Specifically, the lower die base 31 is intermittently arranged, that is, the lower die base 31 is only provided at the position where embossing is required. The upper die base matches the lower die base 31, and the lower die base 31 is arranged into an intermittent structure. The purpose is to avoid the reciprocating operation of the first feeding mechanism 40 and the first material picking mechanism 50.

[0045] The first feeding mechanism 40 includes a first feeding rack 41, a first lifting assembly 42 for driving the first feeding rack 41 to rise and fall, and a first driving assembly 43 for driving the first feeding rack 41 to move laterally. The first feeding mechanism 40 is used to transfer multiple long tubes placed on the receiving rack 21 to the lower mold base 31 of the embossing mechanism 30.

[0046] The first material picking mechanism 50 includes a first material picking rack 51, a second lifting assembly 52 that drives the first material picking rack 51 to rise and fall, and a second driving assembly 53 that drives the first material picking rack 51 to move laterally. The first material picking mechanism 50 is used to transfer the long tube embossed by the embossing mechanism 30 out of the embossing mechanism 30.

[0047] The flipping mechanism 60 includes a bracket 61, a plurality of turntables 62 rotatably mounted on the bracket 61, and a driving member B63 for driving the turntable 62 to rotate. The outer peripheral end of the turntable 62 is provided with a plurality of groups of circumferentially spaced receiving grooves 621, and the inner end of the turntable 62 corresponding to the receiving grooves 621 is provided with a magnetic suction member 622 for adsorbing the long tube; specifically, the plurality of turntables 62 are fixed at intervals on a longitudinally arranged connecting shaft, and the connecting shaft is rotatably connected to the bracket 61. The driving member B63 drives the connecting shaft to rotate, thereby synchronously driving the plurality of turntables 62 to rotate.

[0048] The transfer mechanism 70 includes an endless conveyor belt 71 and a fixed seat 72 fixed on the endless conveyor belt 71. The fixed seat 72 is provided with a recess 721 for placing the long tube. The long tube in the receiving groove 621 can be transferred into the recess 721 through the side wall of the recess 721 of the fixed seat 72. The long tube is turned over from the time it enters the receiving groove 621 of the turntable 62 to the time it is transferred out of the receiving groove 621. Specifically, when the long tube in the receiving groove 621 is rotated to the position corresponding to the fixed seat 72, the long tube in the receiving groove 621 can be transferred into the recess 721 through the limiting means on both sides of the recess 721 of the fixed seat 72.

[0049] The long tube automatic conveying and embossing device of the present invention can not only realize the loading, feeding, embossing, taking, flipping and transferring of multiple long tubes, but also can efficiently operate the long tubes at each workstation, thereby greatly improving the processing efficiency of the long tubes.

[0050] In some embodiments, a second feeding mechanism 80 is further provided between the embossing mechanism 30 and the flipping mechanism 60. The second feeding mechanism 80 includes a second feeding rack 81 and a third driving assembly 82 that drives the second feeding rack 81 to move laterally. The long tubes at the first picking mechanism 50 are transferred to the second receiving rack 21. The third driving assembly 82 drives the second feeding rack 81 to move laterally to transfer the long tubes on the second receiving rack 21 one by one to the receiving slots 621 of the turntable 62. Specifically, the second feeding mechanism 80 also includes a second connecting rack. The second feeding rack 81 is provided in multiple groups and is longitudinally spaced apart on the second connecting rack. The third driving assembly 82 can drive the second connecting rack to move laterally, thereby driving multiple groups of second feeding racks 81 to move synchronously to synchronously transfer the long tubes. Through the setting of the second feeding mechanism 80, the material picking efficiency of the first material picking mechanism 50 and the flipping efficiency of the flipping mechanism 60 can be effectively matched, so as to better match the long tube processing and operation of each workstation. Specifically, the first material picking mechanism 50 is faster and the operation speed of the flipping mechanism 60 is relatively slow. The second feeding mechanism 80 can reduce the waiting time of the first material picking mechanism 50.

[0051] In some embodiments, the first feeding mechanism 40 includes a support frame A44, and the first drive assembly 43 includes a support base A431, a rotating shaft A432, and a feeding motor A433. The support base A431 is provided in multiple groups and spaced apart on the support frame A44. The rotating shaft A432 is rotatably mounted on the support frame A44. The feeding motor A433 is used to drive the rotating shaft A432. The first feeding frame 41 is provided with multiple groups and spaced apart and slidably mounted on the support frame A431. The lower end of the first feeding frame 41 is provided with a rack portion A411, and the rotating shaft A432 is provided with a gear A4321 that meshes with the rack portion A411. The first drive assembly 43 using the feeding motor A433, the rack portion A411, and the gear A4321 can effectively save space.

[0052] In some embodiments, the first lifting assembly 42 includes a base A421 and a lifting cylinder A422 arranged on the base A421 for driving the support frame A44 to lift vertically. Guide sleeves A are fixedly provided on both sides of the base A421, and guide columns A guided by the guide sleeves are provided at both ends of the support frame A44. A first synchronization mechanism 45 is provided at both ends of the base A421. The first synchronization mechanism 45 includes a rack portion B451 vertically arranged on the base A421, and the two ends of the base A421 are rotatably connected with a gear B452 engaged with the corresponding rack portion B451. Through the setting of the first synchronization mechanism 45, it can effectively ensure that the support frames A44 at both ends can be lifted and lowered synchronously, and it can effectively ensure that the first feeding racks 41 at both ends of the support frame A44 maintain synchronous lifting and lowering, avoiding the problem of one end being high and the other end being low, thereby solving the problem of not being able to smoothly transport long pipes.

[0053] In some embodiments, the first material picking mechanism 50 includes a support frame B54, the second driving assembly 53 includes a support seat B531, a rotating shaft B532 and a material picking motor B533, the support seat B531 is provided with multiple groups and is arranged at intervals on the support frame B54, the rotating shaft B532 is rotatably mounted on the support seat B531, and the material picking motor B533 is used to drive the rotating shaft B532 to operate, the first material picking frame 51 is provided with multiple groups at intervals and is laterally slidably mounted on the support frame B531, the lower end of the first material picking frame 51 is provided with a rack portion C511, and the rotating shaft B532 is provided with a gear C5321 that meshes with the rack portion C511 for transmission. By adopting the second driving assembly 53 of the feeding motor B, the rack portion C511 and the gear C5321, it is possible to effectively save space and reduce the overall length of the long tube conveying and embossing device.

[0054] In some embodiments, the second lifting assembly 52 includes a base B521 and a lifting cylinder B522 mounted on the base B521 for driving the support frame B54 to vertically lift. A second synchronization mechanism 55 is mounted at each end of the base B521. The second synchronization mechanism 55 includes a rack portion D551 mounted vertically on the base B521. Both ends of the base B521 are rotatably connected to gears D552 that mesh with the corresponding rack portions D551. The provision of the second synchronization mechanism 55 effectively ensures that the support frames B54 at both ends can be raised and lowered synchronously, effectively ensuring that the first material retrieving racks 51 at both ends of the support frame B54 remain raised and lowered synchronously, avoiding the problem of one end being higher than the other, thereby resolving the problem of being unable to smoothly transport long pipes.

[0055] In some embodiments, the receiving rack 21, the first feeding rack 41 and the first material taking rack 51 are respectively provided with a plurality of placement openings spaced laterally apart, and the number and spacing of the placement openings on the receiving rack 21, the first feeding rack 41 and the first material taking rack 51 are consistent. Specifically, the number of mold cavities and the spacing of the mold cavities of the lower mold base 31 are the same as the placement openings of the first feeding rack 41 and the first material taking rack 51. Through this setting, it is possible to synchronously transfer multiple long tubes and synchronously emboss multiple long tubes, thereby effectively improving the transportation efficiency and embossing efficiency of the long tubes.

[0056] In some embodiments, the loading mechanism 10 is further provided with a stop mechanism 15 for limiting the single discharge quantity of the blanking port of the blanking track 14. The stop mechanism 15 includes a stop cylinder 151 and a stop block 152 connected to the output end of the stop cylinder 151. The stop cylinder 151 is fixedly connected to the frame 11. For example, the blanking port width of the blanking track 14 allows three long tubes to be discharged at a time. Depending on the product, sometimes only two are needed at a time. Then, by setting the stop mechanism 15, when three long tubes need to be discharged each time, the stop mechanism 15 retracts to the initial position. When two long tubes need to be discharged each time, the stop mechanism 15 drives the stop block 152 to extend to the stop position. By setting the stop mechanism 15, the feeding mechanism 10 is made more versatile.

[0057] In some embodiments, the angle of rotation of the turntable 62 from receiving the long tube on the second feeding rack 81 to transferring the long tube into the recess 721 of the fixed seat 72 is 180°. Of course, as an equivalent alternative, the angle of rotation of the turntable 62 from receiving the long tube on the second feeding rack 81 to transferring the long tube into the recess 721 of the fixed seat 72 can be close to 180°.

[0058] The long tube automatic conveying and embossing device of the present invention, through the design of the flipping mechanism 60, on the one hand plays the function of flipping the long tube so that the embossed part of the long tube is set upward, and on the other hand plays a storage function, that is, the long tube is stored in the accommodating groove 621 of the turntable 62, which can effectively save the length and space of the equipment.

[0059] The above description is only a preferred embodiment of the present invention.
