Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment for ton barrel frames, and particularly to an automatic short pipe conveying and embossing device. Background Art

[0002] A ton barrel frame is a frame structure suitable for supporting and fixing a ton barrel. The ton barrel frame is composed of a chassis and a frame body. The frame body is welded by steel pipes, and the chassis is made of galvanized thin steel plates with rounded corners. Among them, the frame body is used to prevent the ton barrel from being damaged due to external impacts, so the frame body needs to have a relatively high structural strength. Currently, the frame bodies are mainly divided into round pipe type frames and square pipe type frames. The round pipe type frame is a frame made of round steel pipes; the square pipe type frame is a frame made of square steel pipes.

[0003] Currently, in the prior art, the production process flow of the frame body is mainly as follows: First, both ends of the horizontal steel pipes are respectively subjected to hole expansion and pipe shrinking treatments (specifically, reference can be made to a forming machine for realizing hole expansion and pipe shrinking of pipe fittings with a patent number of CN211489354U) to facilitate subsequent docking. Then, the horizontal steel pipes and vertical steel pipes are arranged horizontally and vertically in a cross pattern. For the sake of easy understanding, hereinafter, the horizontal steel pipes are collectively referred to as long pipes, and the vertical steel pipes are collectively referred to as short pipes. Welding and fixing are carried out at the joints of the long pipes and short pipes to obtain a metal grid. The metal grid is bent into a cylindrical structure. Then, the horizontal steel pipes that have completed the hole expansion and pipe shrinking treatments are butt-jointed at the head and tail through external equipment. Finally, punching and riveting are carried out at the butt-joint at the head and tail to obtain the frame body.

[0004] Before welding the long pipes and short pipes of the round pipe type frame, it is necessary to first emboss the welding parts of the long pipes and short pipes, that is, to press the welding parts of the long pipes and short pipes inward by a certain depth so that this position is pressed into a flat structure, thereby facilitating the welding of the long pipes and short pipes. However, the existing conveying and embossing of long pipes and short pipes have not realized a fully automatic systematic production line, and manual feeding, transfer, and material taking are required, which not only has low efficiency but also cannot guarantee the operation safety. The present invention improves the production line for automatic conveying and embossing of short pipes. Summary of the Invention

Detailed implementation manners

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] As Figures 1-11As shown in the figure, the short pipe automatic conveying and embossing device includes a feeding mechanism 10, a transition mechanism 20, an embossing mechanism 30, a material grabbing mechanism 40, and a material transporting mechanism arranged in sequence. The feeding mechanism 10 is used for sorting and feeding short pipes. The feeding mechanism 10 includes a frame, a storage cavity 12 arranged in a V shape, a lifting component 13 for lifting the short pipes at the discharge port of the storage cavity 12 to a certain height, and a blanking track 11 for guiding and sorting the short pipes. The storage cavity 12, the lifting component 13, and the blanking track 11 are arranged in sequence along the frame from right to left. The storage cavity 12 is used for storing short pipes. A guiding part is arranged on the lower wall of the storage cavity 12 along the discharge port direction of the storage cavity 12. The lifting component 13 is a chain-type lifting structure, and the lifting component 13 is used to lift the short pipes at the discharge port of the storage cavity 12 to the inlet of the track groove 111 of the blanking track 11. The short pipes arranged in the track groove 111 are discharged through the discharge port at the lower end of the track groove 111 under the action of their own gravity.

[0032] The transition mechanism 20 is arranged between the feeding mechanism 10 and the embossing mechanism 30. The transition mechanism 20 includes a base 21, a first receiving component 22, and an alignment component 23 arranged on the base 21. The first receiving component 22 includes a first receiving frame 221 and a first driving mechanism 222 for driving the first receiving frame 221 to reciprocate between the alignment component 23 and the feeding mechanism 10. The first receiving frame 221 can receive multiple short pipes arranged horizontally at intervals. Further, the feeding mechanism 10 includes blanking tracks 11 arranged on both sides. The blanking tracks 11 have track grooves 111 for defining the movement trajectories of the short pipes. The lower ends of the blanking tracks 11 corresponding to the track grooves 111 have discharge ports. The first receiving frame 221 is provided with notches with open upper ends. A plurality of notches are arranged and spaced horizontally. The short pipes arranged in the track grooves 111 fall into the notches of the first receiving frame 221 through the discharge ports. The upper end surface of the first receiving frame 221 can block the short pipes in the track grooves 111 from falling through the discharge ports. A blocking part 2211 is arranged on the right side of the first receiving frame 221, so that when the first receiving frame 221 moves to the alignment component 23, the short pipes at the discharge ports are blocked by the blocking part 2211. The first receiving frame 221 moves to the left under the drive of the first driving mechanism 222, so that the short pipes arranged in the track grooves 111 are placed one by one into each notch of the first receiving frame 221 through the discharge ports until all the notches in the first receiving frame 221 are filled. The first receiving frame 221 moves to the position where the alignment component 23 is located under the action of the first driving mechanism 222. At this time, the discharge ports of the blanking tracks 11 are blocked by the blocking part 2211 to prevent the short pipes from falling from the discharge ports.

[0033] The alignment component 23 is used to align both ends of the short tube to the set positions. The alignment component 23 includes an alignment structure A231 arranged at the rear side of the base 21 and an alignment structure B232 arranged at the front side of the base 21 and facing the alignment structure A231. The alignment structure A231 includes a bracket A2311 fixedly connected to the base 21, a telescopic cylinder A2312 connected to the bracket A2311, and a positioning plate A2313 connected to the output end of the telescopic cylinder A2312. The alignment structure B232 includes a bracket B2321 connected to the base 21, a telescopic cylinder B2322 connected to the bracket B2321, and a positioning plate B2323 connected to the output end of the telescopic cylinder B2322. An adjusting mechanism 24 for adjusting the distance between the bracket B2321 and the bracket A2311 is arranged on the base 21. The adjusting mechanism 24 includes an adjusting cylinder fixedly arranged on the base 21. The bracket B2321 is vertically slidably arranged on the base 21 through a slide rail. The front and rear position of the bracket B2321 can be adjusted by the adjusting cylinder, so as to adjust the distance between the alignment structure B232 and the alignment structure A231. The longitudinal position of the short tube is calibrated and aligned through the cooperation of the positioning plate A2313 and the positioning plate B2323, that is, the front and rear position of the short tube is calibrated and aligned. In the automatic feeding and embossing device for short tubes of the present invention, by arranging the adjusting mechanism 24 at the alignment structure B232 of the alignment component 23, the position of the alignment structure B232 relative to the alignment structure A231 is adjusted according to the size of the short tube, so that the alignment component 23 can be adapted to short tubes of different sizes.

[0034] The embossing mechanism 30 is used to flatten the set positions of multiple short tubes placed in its mold cavity to the required flat-shaped structure. The embossing mechanism 30 is a conventional structure. Multiple bottom molds 31 arranged at longitudinal intervals are arranged in the embossing mechanism 30. The bottom mold 31 has a mold cavity with an upper opening. A top mold 32 matched with the base 21 and a press for driving the top mold 32 to move vertically up and down are arranged at the upper end of the embossing mechanism 30. The position where the bottom mold 31 is located is the position where the short tube needs to be embossed. The bottom mold 31 is arranged in multiple sections for the purpose of avoiding the horizontal movement of the feeding mechanism 60. Specifically, the feeding mechanism 60 needs to reciprocate between the alignment mechanism and the grasping mechanism 40.

[0035] The feeding mechanism 60 is arranged at the embossing mechanism 30. The feeding mechanism 60 includes a feeding frame 61, a driving member A62 for driving the feeding frame 61 to reciprocate horizontally, and a lifting assembly 63 for driving the feeding frame 61 to lift. The feeding frame 61 is provided with a first receiving portion 611 and a second receiving portion 612 for placing multiple short tubes. During the process of the first receiving portion 611 transferring the short tubes at the transition mechanism 20 to the embossing mechanism 30, the second receiving portion 612 can synchronously transfer the short tubes at the embossing mechanism 30 to the material grabbing mechanism 40. Specifically, when the first receiving portion 611 is receiving materials at the transition mechanism 20, the second receiving portion 612 is performing embossing operations at the embossing mechanism 30; when the first receiving portion 611 is performing embossing operations at the embossing mechanism 30, the second receiving portion 612 is discharging materials at the material grabbing mechanism 40.

[0036] A feeding mechanism 70 is arranged at one end of the material transporting mechanism 50 close to the embossing mechanism 30. The material grabbing mechanism 40 is used to grab and place the short tubes at the second receiving portion 612 one by one to the feeding mechanism 70. The material transporting mechanism 50 includes an endless conveyor belt 51 and a plurality of positioning portions 52 arranged on the endless conveyor belt 51. The feeding mechanism 70 can be lifted vertically to facilitate placing the short tubes at the feeding mechanism 70 at the positioning portions 52 of the endless conveyor belt 51. Specifically, the positioning portion 52 has a notch with an open upper end, and the notch of the positioning portion 52 is used to place the short tubes. The short tubes at the material transporting mechanism 50 are transferred to the turnover station through a turnover mechanism. Similarly, the material transporting mechanism for transporting long tubes also transfers the long tubes at the material transporting mechanism to the same turnover station through the turnover mechanism, and the long tubes and short tubes are discharged in a cross-shaped structure according to the set requirements at the turnover station.

[0037] In some embodiments, the feeding mechanism 60 further includes a connecting plate 64 fixedly connected to the embossing mechanism 30 and an intermediate support frame 65 slidably arranged at the upper end of the connecting plate 64. In this embodiment, the intermediate support frame 65 is in a square frame structure. The feeding frame 61 is horizontally slidably connected to the intermediate support frame 65. Specifically, a horizontally arranged linear guide rail is fixedly connected to the end face of the feeding frame 61 adjacent to the intermediate support frame 65, and the intermediate support frame 65 is slidably connected to the linear track through a slider, so that the feeding frame 61 and the intermediate support frame 65 are slidably connected as a whole. The driving member A62 is installed on the intermediate support frame 65 for driving the feeding frame 61 to move horizontally relative to the intermediate support frame 65, and the lifting assembly 63 is installed on the connecting plate 64 for driving the intermediate support frame 65 and the feeding frame 61 to lift synchronously.

[0038] In some embodiments, two sets of connecting plates 64 are arranged at intervals, and the two sets of connecting plates 64 are arranged at a lateral interval. A set of lifting components 63 are respectively configured at both ends of the connecting plate 64. The feeding mechanism 60 is provided with a synchronization mechanism 66, and a set of synchronization mechanism 66 is equipped at each connecting plate 64. The synchronization mechanism 66 includes a fixing plate 661 vertically connected to the connecting plate 64. Rack portions 6611 are arranged on both sides of the fixing plate 661. Gears 662 are rotatably connected to both ends of the middle support frame 65. The gears 662 are in meshing transmission with the corresponding rack portions 6611 on the side. By providing the synchronization mechanism 66, it can effectively ensure that both ends of the middle support frame 65 and the feeding frame 61 can be lifted and lowered synchronously, avoiding the problem of one end being high and the other end being low, thereby being able to solve the problems of unable to feed and discharge smoothly. Further, a plurality of hollow portions are provided on the fixing plate 661, and the quality of the fixing plate 661 can be effectively reduced through the hollow portions.

[0039] In some embodiments, the lifting component 63 includes a first cylinder 631 fixedly connected to the lower end of the connecting plate 64 and a guiding component 632 arranged on the connecting plate 64. The guiding component 632 includes guiding cylinders 6321 fixedly connected to the connecting plate 64 and located on both sides of the first cylinder 631, and guiding rods 6322 slidably arranged in the guiding cylinders 6321. The upper ends of the guiding rods 6322 are fixedly connected to the middle support frame 65. Through the guiding component 632, the stability of the synchronous lifting of the middle support frame 65 and the feeding frame 61 can be improved.

[0040] In some embodiments, rotating shafts 651 are respectively arranged at both ends of the middle support frame 65. A clamping block 663 is fixedly connected to the end face of the gear 662. The clamping block 663 is locked by a fastening member so that the gear 662 and the clamping block 663 are fixedly connected to the rotating shaft 651. Through the arrangement of the clamping block 663, the installation convenience of the gear 662 can be effectively improved, that is, it is convenient to install the gear 662 on the rotating shaft 651.

[0041] In some embodiments, the number and arrangement pitch of the notches of the first receiving portion 611 and the second receiving portion 612 match the number and arrangement pitch of the notches of the first receiving frame 221. The number and arrangement pitch of the notches of the first receiving portion 611 and the second receiving portion 612 match the number and arrangement pitch of the die cavities of the embossing mechanism 30. Through this setting, it is convenient for the first receiving portion 611 to smoothly move all the short tubes at the notches of the first receiving frame 221 into the die cavities of the embossing mechanism 30 synchronously. Similarly, it is also convenient for the second receiving portion 612 to synchronously move all the short tubes at the die cavities of the embossing mechanism 30 out of the embossing mechanism 30, thereby being able to effectively improve the feeding efficiency.

[0042] In some embodiments, the material grabbing mechanism 40 includes a fixed frame 41, a cross beam 42 slidably mounted on the fixed frame 41 in the horizontal direction, and a material grabbing frame 43 connected to the cross beam 42 in a liftable manner. A linear guide rail is horizontally arranged on the fixed frame 41, and the cross beam 42 is slidably connected to the linear guide rail through a slider. Rack bars are horizontally arranged at both ends of the fixed frame 41. A driving shaft and a driving motor for driving the driving shaft to rotate are arranged on the cross beam 42. Driving gears meshing with the rack bars are arranged at both ends of the driving shaft. The driving motor drives the driving shaft to operate, thereby driving the cross beam 42 to move along the length direction of the rack bar. A material grabbing cylinder 431 for driving the material grabbing frame 43 to lift is arranged on the cross beam 42.

[0043] The number and arrangement spacing of the notches provided on both sides of the material grabbing frame 43 match the number and arrangement spacing of the notches of the second material receiving portion 612. Adsorbing components for adsorbing the short tubes are arranged at the notches of the material grabbing frame 43. Preferably, the adsorbing components are magnetic blocks. Lower pushing components 44 are arranged on both sides of the fixed frame 41. The lower pushing components 44 are used to push the short tubes adsorbed on the material grabbing frame 43 down onto the material discharging mechanism 70. The lower pushing components 44 are lower pushing cylinders fixed at both ends of the fixed frame 41.

[0044] In some embodiments, a material placing frame 80 is arranged at the lower end of the material grabbing mechanism 40. The number and arrangement spacing of the notches on the material placing frame 80 match the number and arrangement spacing of the notches on the second material receiving portion 612. The second material receiving portion 612 is used to transfer the short tubes at the embossing mechanism 30 onto the material placing frame 80, and the material grabbing mechanism 40 grabs and places the short tubes on the material placing frame 80 one by one onto the material discharging mechanism 70.

[0045] In some embodiments, the material discharging mechanism 70 includes a second cylinder 71 fixedly connected to the fixed frame 41 and a material discharging frame 72 connected to the output end of the second cylinder 71. Notches with open upper ends are arranged on both sides of the material discharging frame 72. The second cylinder 71 drives the material discharging frame 72 to lift and lower to place the short tubes located on the material discharging frame 72 at the positioning portion 52 of the annular conveyor belt 51. When the positioning portion 52 of the annular conveyor belt 51 is about to move to the position where the material discharging frame 72 is located, the second cylinder 71 drives the material discharging frame 72 to move downward so that the short tubes at the notches of the material discharging opening can be exactly placed in the positioning portion 52 of the annular conveyor belt 51.

[0046] In summary, the present invention has the following beneficial effects: 1. The short tube automatic conveying and embossing device of the present invention can realize processes such as automatic feeding, alignment, feeding, embossing, and material taking of short tubes, greatly improving the transfer efficiency and embossing efficiency, and effectively improving the operation safety. 2. For the short tube automatic conveying and embossing device of the present invention, the feeding mechanism 60 can achieve synchronous feeding and discharging of short tubes, effectively saving the time for feeding short tubes into the embossing mechanism 30 and taking them out of the embossing mechanism 30, and greatly improving the embossing efficiency of short tubes. Specifically, when the first material receiving part 611 transfers the short tubes at the transition mechanism 20 to the embossing mechanism 30, the second material receiving part 612 can synchronously transfer the short tubes at the embossing mechanism 30 to the material grabbing mechanism 40.
