The working principle of the invention is explained and illustrated below in connection with a first workflow:
Firstly, an external feeding mechanism 8 conveys a sheet from right to left, the sheet passes through the portal frame 11 and then is conveyed onto the upper pressing part 32 to be reset, then the upper pressing part 32 ascends and drives the sheet to ascend until the upper pressing part 32 and the lower pressing part 31 clamp the sheet together, at the moment, the two forming devices 4 are pressed on the upper surface of the sheet and are positioned at the inner corners of the barrel body, and finally, the two folding devices 5 fold the two ends of the sheet upwards along the corresponding forming devices 4 and then mutually overlap to form the barrel body, wherein buckling positions are prefabricated at the two end edges of the sheet, so that overlapping fixation can be realized after the two end edges of the sheet are contacted.
Therefore, compared with the traditional manual bending, the automatic bending mode of the invention improves the production efficiency, and simultaneously, the two groups of turnover devices 5 are matched with the two groups of forming devices 4 to bend the two ends of the sheet at the same time, thereby further improving the bending efficiency and leading the invention to have the advantages of high bending efficiency and low manpower resource cost.
It will be appreciated that in one embodiment, since the two ends of the sheet are folded over 180 ° at a time and then overlap each other, when the two folding devices 5 are reset, a large bending rebound occurs at the folded corner of the tub. In order to reduce the influence of bending resilience of the sheet on the shaping quality of the barrel, each end of the barrel should be divided into a plurality of corners to realize 180 DEG bending between the end edge of the sheet and the sheet main body.
Therefore, please continue to refer to fig. 3 and 4, each molding device 4 includes a molding member 41 and a first linear module 42, wherein the first linear module 42 is mounted on the gantry 11 of the frame 1, and the molding member 41 is mounted on the first linear module 42 and is driven by the first linear module 42 to move horizontally opposite to or opposite to the pressing member 31. Each turnover device 5 comprises a second linear module 51 and a turnover module 52, the second linear module 51 is arranged on the bearing platform 21, the turnover module 52 is arranged on the second linear module 51 and driven by the second linear module 51 group to horizontally move opposite to or back to the upper pressing part 32, and the turnover module 52 comprises a power device 521 and a bending part 522 driven by the power device 51 to rotate.
Further, the molding member 41 includes a molding column 411 and a second slide 412, the second slide 422 is slidably mounted on the gantry 11 through a third rail pair 413, the molding column 411 is disposed along a left-right direction for molding a bent round corner inside the barrel body, and a left end thereof is detachably connected to a shaft sleeve 414 of the second slide 412.
The following is explained and illustrated in connection with the second workflow:
Firstly, an external feeding mechanism 8 conveys a sheet material to the upper pressing part 32, then, the upper pressing part 32 moves upwards and drives the sheet material to move upwards until the upper pressing part 32 and the lower pressing part 31 clamp the sheet material together, at the moment, the two forming devices 4 are pressed on the upper surface of the sheet material and are positioned at the inner corners of the barrel body, then, the two folding devices 5 fold the two ends of the sheet material upwards by 90 degrees to form a semi-finished product with wing plates at the two ends, and reset, then, the two first linear modules 42 work and respectively drive the two forming parts 41 to gather, meanwhile, the two second linear modules 52 respectively drive the two turnover 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 the wing plates at the two ends of the semi-finished product are mutually overlapped to form the barrel body.
Of course, according to different demands of bending shapes of the barrel body, two ends of the sheet material can be overlapped after being bent for more than two times, and in addition, according to different hardness of the sheet material, the turnover angle of the sheet material is preferably 90-180 degrees each time. The bending member 522 may push the end of the sheet to adhere to the outer surface of the forming column 411 to complete the bending operation in the process of rotating the sheet from the lower side of the sheet, or the bending member 522 may absorb the sheet from the edge of the upper surface of the sheet by using a suction nozzle or the like and pull the end of the sheet to bend to adhere to the outer surface of the forming column 411 in the process of rotating the sheet.
With continued reference to fig. 5, it can be understood that in one embodiment, the bending member 522 bends by pushing a sheet, specifically, the power device 521 is a motor, a gear 523 is sleeved on an output shaft of the motor, and the folding module 52 includes a first slide seat 524, a mounting post 525, a gear shaft 526, a die mounting seat 527, and the bending member 522. The first sliding seat 524 is mounted 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, the sheet teeth of the gear shaft are meshed with the gear 523 to realize gear transmission, one end of the cutter die mounting seat 527 is fixedly connected to the mounting column 525, one end, close to the forming device 4, of the upper portion of the cutter die mounting seat 527 is provided with a mounting notch, and the bending part 522 is detachably mounted on the mounting notch through a bolt.
In this embodiment, the folding device 5 operates according to the principle that the motor is connected to an external power source 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 member 522 to rotate.
In addition, since the bending part 522 is detachably mounted on the mounting notch, the bending part 522 with different types can be flexibly replaced according to the material, the size and the thickness of the sheet material 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 large-sized barrels, and the power device 521 and the bending component 522 are packaged in a gear transmission mode, so that slipping caused by overlarge load of bending operation can not occur when the power device 521 and the bending component 522 are transmitted, and the invention has the advantage of stable and reliable work.
With continued reference to fig. 4, it will be understood that in other embodiments, the bending member 522 is not coaxial with the gear shaft 526, and the rotating path of the bending member 522 is coaxial with the corresponding forming device 4 when bending the sheet, so that the bending member 522 can rotate around the corresponding forming device 4 to further push the end of the sheet to be pressed against the corresponding forming device 4, and meanwhile, the bending member 522 has a plate-shaped structure, so that the bending member 522 can form a line contact with the sheet when rotating, so that the sheet can flow freely during bending, and the bending position 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 turndown devices 5 is provided with a first sensing component 53 for detecting whether the advancing direction of the sheet is wrong.
Specifically, the first sensing member 53 may be a micro switch or a touch switch, and in the actual use process, the feeding mechanism 8 sends the sheet to the upper surface of the pressing member 32 along the horizontal direction, and in order to avoid the error of the feeding position of the workpiece, the first sensing member 53 is used as a detecting device to determine whether the feeding mechanism drives the sheet to advance. Furthermore, in order to avoid the error of the horizontal placement angle of the sheet, the invention is provided with two first sensing components 53 at the same time, when the two first sensing components detect the sheet at the same time, an external industrial control system judges that the sheet is placed in place and has no error of the placement angle in the horizontal direction, and the subsequent operation is started, when only one of the first sensing components 53 detects the sheet, the external industrial control system judges that the feeding mechanism 8 feeds the sheet to the place, but the placement angle in the horizontal direction of the sheet is error, and at the moment, the feeding structure 8 brings the sheet back and rewinds the sheet.
With continued reference to fig. 1 and 5, it may be understood that in other embodiments, the positioning device 6 further includes a third linear module 61 disposed on the frame 1, and a positioning fork 62 driven by the third linear module 61 to move horizontally opposite to or opposite to the sheet on the pressing device 6, where at least two second sensing members 621 are disposed on the positioning fork 62, and the first sensing members 53 and the second sensing members 621 are respectively matched with two adjacent side edges of the sheet.
In a specific use, the first sensing component 53 only monitors the position of the sheet in the left-right direction and the placement angle of the horizontal plane of the sheet, and the sheet may still have a position deviation in the front-rear direction at this time, because the third linear module 61 drives the second sensing component 621 to move so as to detect the actual coordinates of the sheet in the front-rear direction, and after the actual coordinates are sent to the industrial control system, the industrial control system correspondingly adjusts the processing origin coordinates of the forming device 4 and the turnover device 5, thereby improving the precision of forming the barrel body and reducing the defective rate.
With continued reference to fig. 2, it will be appreciated that in other embodiments, in order to prevent the sheet from being displaced during the process of driving the sheet upward by the upper pressing member 32, the present invention further provides an adsorption device 7 for fixing the sheet to the upper pressing member 32 during the process of driving the upper pressing member 32 upward.

The top of the installation large plate 22 is fixedly connected with the frame 1. The bearing platform slide plate 23 is slidably mounted on the other side of the installation large plate 22 up and down through four sets of first guide rail pairs 232, the top of the bearing platform slide plate is fixedly provided with the bearing platform 21, and reinforcing ribs 231 are connected between the bearing platform 21 and the bearing platform 21, so that the installation stability of the bearing platform 21 and the rigidity during movement are improved. The side brackets are disposed on both sides of the installation large plate 22 opposite to the table slide plate 23. The auxiliary pressing pushing block 25 is slidably mounted on the side bracket 24 through a second guide rail pair 251, and the top end of the auxiliary pressing pushing block is fixedly connected with one end of the upper pressing member 32 away from the bearing platform 21.

The second screw pair 28 is in power connection with the servo motor 281 and drives the auxiliary pressing pushing block 25 to slide up and down.
Because the upper pressing part 32 is longer and only has the left end and the bearing platform 21, the right end of the upper pressing part 32 may droop during pressing operation, so that the problem of insufficient pressing force of the right end of the upper pressing part 32 finally results in sheet displacement and reduces bending quality of the barrel body, and therefore, the auxiliary pressing push 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 when clamping the sheet, and finally the reject ratio of the invention is reduced.
With continued reference to fig. 2, it can be appreciated that in other embodiments, the first pulley 271 and the second pulley 272 are sequentially sleeved on the bottom end of the first screw pair 27 from top to bottom.

The bottom end of the screw rod of the second screw rod pair 28 is sleeved with a fourth belt wheel 281, and the fourth belt wheel 281 and the second belt wheel 272 are the same in size and are in power connection through a second synchronous belt 274. The bottom of the side bracket 24 is further provided with a tensioning wheel 241 for adjusting the tension of the second synchronous belt 274. Due to the adoption of the structure that the servo motor 26 synchronously drives the bearing platform and the auxiliary pressing push block 25, the structure of the invention is more compact, and the manufacturing cost is reduced.
Finally, it should be further understood that the first, second and third linear modules 42, 51 and 61 may be directly selected from a commercial slipway cylinder, a ball screw linear module, a synchronous belt linear module, a linear motor, etc., and in this embodiment, the first, second and third linear modules 42, 51 and 61 are ball screw linear modules.
