Referring to fig. 1-5, a fully automatic bending mechanism for a barrel includes: the top of the frame 1 is provided with a portal frame 11 arranged along the front-back direction; the lifting device 2 is arranged on the rack 1 opposite to the portal frame 11 and drives the bearing platform 21 to move upwards; a pressing device 3 including a pressing member 31 and a pressing member 32; the pressing component 31 is long and is arranged along the left-right direction, and the right end of the pressing component is arranged on the portal frame 11; the upper pressing component 32 is also long, is arranged along the left-right direction, and the left end of the upper pressing component is fixedly arranged on the bearing platform 21 and can move upwards along with the bearing platform 21 to cooperate with the lower pressing component 31 to press the sheet; the two groups of forming devices 4 are respectively arranged on the portal frame 11, are positioned on the front side and the rear side of the lower pressing part 31 and are matched with the bending angle inside the barrel body; and the two groups of turnover devices 5 are arranged on the bearing platform 21, correspond to the two groups of forming devices 4 one by one, and can rotate to bend the sheet into a barrel body by matching the corresponding forming devices 4.

The working principle of the invention is explained and illustrated below with reference to a first workflow:

firstly, the external feeding mechanism 8 conveys the sheet from right to left, and the sheet passes through the portal frame 11, is conveyed to the upper pressing component 32 and then is reset; then, the upper pressing part 32 moves upwards and drives the sheet to move upwards until the upper pressing part 32 and the lower pressing part 31 clamp the sheet together, and at the moment, the two forming devices 4 are pressed on the upper surface of the sheet and are positioned at the inner corner of the barrel body; finally, the two folding devices 5 fold the two ends of the sheet upwards along the corresponding forming devices 4 and then are mutually overlapped to form a barrel body; wherein, the both ends reason of sheet material is equipped with the lock joint position in advance, so can realize the overlap joint after its both ends reason contacts and fix.

Therefore, compared with the traditional manual bending mode, the automatic bending mode improves the production efficiency; meanwhile, the two groups of folding devices 5 and the two groups of forming devices 4 are matched to simultaneously bend the two ends of the sheet, so that the bending efficiency is further improved, and the sheet bending machine has the advantages of high bending efficiency and low human resource cost.

It will be appreciated that in one embodiment, as the two ends of the sheet material overlap after being folded by more than 180 ° at one time, the folded corners of the tub will have a large bending spring back when the two folding devices 5 are reset. In order to reduce the impact of the bending spring back of the sheet material on the forming quality of the tub, each end of the tub should be bent 180 ° between the end edge of the sheet material and the main body of the sheet material with a plurality of corners.

Therefore, please continue to refer to fig. 3 and 4; each forming device 4 comprises a forming part 41 and a first linear module 42, wherein the first linear module 42 is installed on the portal frame 11 of the rack 1; the forming member 41 is mounted on the first linear module 42 and is driven by the first linear module 42 to move horizontally toward or away from the pressing member 31. Each of the folding devices 5 includes a second linear module 51 and a folding module 52; the second linear module 51 is mounted on the bearing platform 21; the turnover module 52 is installed on the second linear module 51, and is driven by the second linear module 51 to move horizontally toward or away from the upper pressing part 32; the folding module 52 includes a power unit 521 and a folding member 522 driven by the power unit 51 to rotate.

Further, the forming part 41 includes a forming column 411 and a second sliding seat 412; the second sliding seat 422 is slidably mounted on the gantry 11 through a third guide rail pair 413 in a front-back manner; the forming column 411 is arranged along the left-right direction and used for forming a bending fillet inside the barrel body, and the left end of the forming column is detachably connected to the shaft sleeve 414 of the second sliding seat 412.

The following is explained and illustrated in connection with the second workflow:

first, the external feeding mechanism 8 conveys the sheet material to the upper pressing member 32; then, the upper pressing part 32 moves upwards and drives the sheet to move upwards until the upper pressing part 32 and the lower pressing part 31 clamp the sheet together, and at the moment, the two forming devices 4 are pressed on the upper surface of the sheet and are positioned at the inner corner of the barrel body; then, the two folding devices 5 fold the two ends of the sheet upwards by 90 degrees to form a semi-finished product with wing plates at the two ends, and then reset; then, the two first linear modules 42 work to respectively drive the two forming parts 41 to gather together, and meanwhile, the two second linear modules 52 respectively drive the two turning modules 52 to synchronously move along with the corresponding forming parts 41; and finally, the two folding devices 5 fold the two ends of the semi-finished product upwards by 90 degrees, so that wing plates at the two ends of the semi-finished product are mutually overlapped to form a barrel body.

Of course, according to different requirements of the bending shape of the barrel body, two ends of the sheet material can be lapped after being bent for more than two times; further, each folding angle of the sheet is preferably 90 ° to 180 °, depending on the hardness of the sheet. The bending component 522 may push the end of the sheet to be attached to the outer surface of the forming column 411 to complete the bending action in the process of rotating upward from the lower side of the sheet; the bending member 522 may be a suction nozzle or the like that sucks the sheet from the edge of the upper surface of the sheet and pulls the end of the sheet to be bent to be closely attached to the outer surface of the forming post 411 during the rotation process to complete the bending operation.

With continued reference to FIG. 5, it will be appreciated that in one embodiment, the bending member 522 is configured to bend by pushing the sheet material, specifically: the power device 521 is a motor, and an output shaft of the motor is sleeved with a gear 523; the folding module 52 includes a first slide 524, a mounting post 525, a gear shaft 526, a cutter mounting seat 527, and the bending member 522. Wherein, the first slide carriage 524 is installed on the second linear module 51 and is driven by the second linear module 51 to move; the power device 521 is also fixed on the first sliding seat; the mounting column 525 is fixed on the first sliding seat 524, the gear shaft 526 is rotatably sleeved on the mounting column 525, and the plate teeth of the gear shaft are meshed with the gear 523 to realize gear transmission; one end of the cutting die mounting seat 527 is fixedly connected to the mounting column 525, an installation notch is formed in one end, close to the forming device 4, of the upper portion of the cutting die mounting seat 527, and the bending component 522 is detachably installed on the installation notch through a bolt.

In the present embodiment, the operation principle of the folding device 5 is as follows: the motor is connected to an external power supply and drives the gear 523 to rotate, the gear 523 drives the gear shaft 526 to rotate, and the gear shaft 526 drives the bending component 522 to rotate.

In addition, because the bending component 522 is detachably mounted on the mounting notch, the bending component 522 of different types can be flexibly replaced according to the material, size and thickness of the sheet and various processing requirements, so that the invention has the advantages of strong universality and low maintenance cost.

In addition, the invention is mainly used for bending and forming the large-size barrel body, and the power device 521 and the bending component 522 are packaged in a gear transmission mode, so that the phenomenon of slipping caused by overlarge bending operation load is avoided, and the invention has the advantage of stable and reliable operation.

With continued reference to fig. 4, it will be appreciated that in other embodiments, the bending members 522 are not coaxially disposed with respect to the gear shaft 526, and the rotational path of the bending members 522 is coaxial with the corresponding forming device 4 when bending the sheet material; therefore, the bending member 522 can rotate around the corresponding forming device 4, and then the end of the sheet is pushed to be pressed on the corresponding forming device 4, and meanwhile, the bending member 522 has a plate-shaped structure, so that the bending member can be in line contact with the sheet during rotation, the sheet can freely flow in the bending process, and the bending part of the sheet is not easy to break.

With continued reference to fig. 4, it can be understood that in other embodiments, each of the folding devices 5 is provided with a first sensing component 53 for detecting whether the forward direction stroke of the sheet material is incorrect during feeding.

Specifically, the first sensing part 53 may be a micro switch or a touch switch; in actual use, the feeding mechanism 8 feeds the sheet material to the upper surface of the upper pressing member 32 in a horizontal direction; in order to avoid errors in the loading position of the workpiece, the first sensing part 53 is used as a detection device to judge whether the sheet is driven by the feeding mechanism to move forward by an error. Furthermore, in order to avoid the error of the horizontal arrangement angle of the sheets, the invention is provided with two first sensing parts 53 at the same time; when the two first sensing parts detect the sheets simultaneously, an external industrial control system judges that the sheets are placed in place and have no horizontal placing angle error, and starts subsequent operation; when only one of the first sensing parts 53 detects a sheet, the external industrial control system judges that the feeding mechanism 8 feeds the sheet in place, but the placing angle of the sheet in the horizontal direction is wrong, and at the moment, the feeding mechanism 8 brings the sheet back and places the sheet again.

With continuing reference to fig. 1 and 5, it is understood that in other embodiments, a positioning device 6 is further included, and the positioning device 6 includes: the third linear module 61 is arranged on the rack 1; the positioning fork 62 is driven by the third linear module 61 to horizontally move towards or away from the sheet on the pressing device 6; wherein, at least two second sensing parts 621 are arranged on the positioning fork 62; the first sensing part 53 and the second sensing part 621 are respectively matched with two adjacent side end edges of the sheet.

In a specific use, since the first sensing part 53 only monitors the position of the sheet in the left-right direction and the arrangement angle of the horizontal plane of the sheet, the sheet may still have a position deviation in the front-back direction; in the present invention, the third linear module 61 drives the second sensing component 621 to move so as to detect the actual coordinates of the sheet material in the front-back direction, and after the actual coordinates are sent to the industrial control system, the industrial control system adjusts the coordinates of the processing origin of the forming device 4 and the folding device 5 accordingly, thereby improving the precision of barrel forming and reducing the defective rate.

With continued reference to fig. 2, it will be appreciated that in other embodiments, in order to prevent displacement of the sheet material during the upward movement of the sheet material driven by the upper pressing member 32, the present invention further provides suction means 7 for securing the sheet material to the upper pressing member 32 during the upward movement of the upper pressing member 32. The suction device 7 includes a connection member 71, a lifting member 72, and a suction member 73. The connecting member 71 is composed of a bottom plate 711 and a connecting column 712, the bottom plate 711 is located below the upper pressing member 32, and two ends of the bottom plate 711 are respectively connected and fixed with the upper pressing member 32 through one connecting column 712. The lifting component 72 comprises a cylinder 721; the cylinder body of the cylinder 721 is positioned below the bottom plate 711, and the piston rod of the cylinder is vertically arranged and fixedly connected with the bottom plate 711; the cylinder body of the air cylinder 721 is also connected with a push rod 722; the push rod 722 is in guiding fit with a guide sleeve 723 on the base plate 711. The adsorption part 73 comprises a pipe 731, an angle iron 732 and a vacuum nozzle 733; the pipe 731 and the push rod 722 are fixedly connected by penetrating through the end part of the bottom plate 711; one end of the angle bar 732 is connected to the pipe 731, and the other end is provided with the vacuum nozzle 733.

The working principle of the adsorption device 7 is as follows: first, the air cylinder 721 drives the vacuum nozzle 733 upward to be flush with the upper end surface of the pressing member 32; then, the feeding mechanism 8 conveys the sheet to the upper pressing part 32, and at this time, the vacuum suction nozzle 733 is connected to an external air source and sucks the sheet tightly, so that the sheet is fixed on the upper pressing part 32; next, the lifting device 2 drives the upper pressing component 32 to move upwards until the pressing device 3 presses the sheet; finally, the vacuum nozzle 733 releases the sheet, the air cylinder 721 drives the vacuum nozzle 733 to move down and reset, and the turnover device 5 starts to operate.

With continued reference to fig. 2, it is understood that in other embodiments, the lifting device 2 includes a mounting large plate 22, a bearing platform sliding plate 23, a side bracket 24, an auxiliary pressing push block 25, a servo motor 26, a first screw pair 27 and a second screw pair 28. The top of the large installation plate 22 is fixedly connected with the frame 1. The bearing platform sliding plate 23 is installed at the other side of the large installation plate 22 in a vertically sliding manner through four sets of first guide rail pairs 232, the bearing platform 21 is fixed at the top of the bearing platform sliding plate, and a reinforcing rib 231 is connected between the bearing platform 21 and the bearing platform, so that the installation stability and the rigidity during movement of the bearing platform 21 are improved. The side brackets are arranged on both sides of the mounting large plate 22 opposite to the bearing platform sliding plate 23. The auxiliary pressing and pushing block 25 is mounted on the side bracket 24 through a second guide rail pair 251 in a vertically slidable manner, and the top end thereof is fixedly connected with one end of the upper pressing member 32 far away from the supporting platform 21. The servo motor 26 is mounted on the mounting plate 22. The first screw pair 27 is mounted on the mounting plate 22, is in power connection with the servo motor 26, and drives the bearing platform 21 to slide up and down. The second screw pair 28 is in power connection with the servo motor 281 and drives the auxiliary pressing and pushing block 25 to slide up and down.

Since the upper pressing member 32 is long and has only the left end and the bearing platform 21, the right end of the upper pressing member 32 may droop during the pressing operation, so that the problem of insufficient pressing force of the right end of the upper pressing member 32 occurs, and finally, the sheet is displaced and the bending quality of the barrel body is reduced; therefore, the auxiliary pressing pushing block 25 is adopted to provide auxiliary pressing force from the right end of the upper pressing part 32, so that the pressing device 3 is more stable in clamping sheets, and the reject ratio of the invention is finally reduced.

With continued reference to fig. 2, it can be understood that in other embodiments, the first pulley 271 and the second pulley 272 are sequentially sleeved on the bottom end of the lead screw of the first lead screw pair 27 from top to bottom. The output shaft of the servo motor 26 is sleeved with a third belt wheel 261, and the third belt wheel 261 and the first belt wheel 271 are in power connection through a first synchronous belt 273. A fourth belt pulley 281 is sleeved at the bottom end of the screw rod of the second screw rod pair 28; the fourth pulley 281 is the same size as the second pulley 272 and is dynamically connected by a second timing belt 274. The bottom of the side bracket 24 is further provided with a tension pulley 241 for adjusting the tension of the second timing belt 274. Due to the adoption of the structure that the servo motor 26 synchronously drives the bearing platform and the auxiliary pressing and pushing block 25, the structure of the invention is more compact, and the manufacturing cost is reduced.

Finally, it should be understood that the first linear module 42, the second linear module 51, and the third linear module 61 may be directly selected from a commercially available sliding table cylinder, a ball screw linear module, a synchronous belt linear module, a linear motor, and the like, and in this embodiment, the first linear module 42, the second linear module 51, and the third linear module 61 are all ball screw linear modules.

The technical scope of the present invention is not limited to the above embodiments, and any modifications, equivalent variations and modifications made to the above embodiments according to the technical spirit of the present invention still fall within the technical scope of the present invention.
