The transmission shafts 33 are rotationally connected to the interiors of the No.2 mounting frames 32. Each pair of transmission wheels 34 is fixedly installed on the outer side of one transmission shaft 33. The driving end of the driving assembly 31 is in transmission connection with one end of the transmission shaft 33. The two pairs of transmission wheels 34 are each provided with a guide slot 341 on one side. One end of the lifting transmission rod 35 and the pushing transmission rod 37 is rotationally connected to one side of the No.2 mounting frame 32. The other end of the lifting transmission rod 35 and the pushing transmission rod 37 is respectively arranged in the interior of the guide slot 341. The pushing plate 38 is slidably connected to the bottom end of the interior of the No.2 mounting frame 32. One side of the lifting plate 36 is slidably connected to one side of the pushing plate 38. The other side of the other end of the lifting transmission rod 35 is slidably connected to the other side of the lifting plate 36. The other side of the other end of the pushing transmission rod 37 is slidably connected to the other side of the pushing plate 38. One side of the lifting plate 36 is fixedly connected with a material pushing rod 39. One end of the material pushing rod 39 is fixedly connected with a pushing cross plate 391.

[0035] The driving assembly 31 drives the transmission shafts 33 to rotate. The transmission shafts 33 drive the two pairs of transmission wheels 34 to rotate. The pushing transmission rod 37 drives the pushing plate 38 to reciprocatingly push. The lifting plate 36 reciprocatingly rises and falls on one side of the pushing plate 38 under the transmission of the lifting transmission rod 35. The lifting plate 36 drives the material pushing rod 39 and the pushing cross plate 391 to push the plate to be bent to one side of the conveying assembly 6.

[0036] In this embodiment, during the reciprocating feeding operation of the automatic feeding assembly 3, the action flow and component linkage logic are as follows:

[0037] Plate pushing stage

[0038] The driving motor in the driving assembly 31 is started, and the transmission is operated at a preset transmission ratio. The power after the transmission treatment is transmitted to the transmission shaft 33, and the transmission shaft 33 is uniformly rotated around its own axis. The transmission shaft 33 synchronously drives the two pairs of transmission wheels 34 assembled at both ends to synchronously rotate. One of the transmission wheels 34 is provided with a guide groove 341 on one side, and the guide groove 341 guides one end of the pushing transmission rod 37, and the other end of the pushing transmission rod 37 slides along the track of the guide groove 341, so that the pushing transmission rod 37 rotates around the hinge point. The other end of the pushing transmission rod 37 applies a driving force to the pushing plate 38, drives the pushing plate 38 to move in the horizontal direction towards the plate to be sent, and synchronously drives the pushing plate 391 to move forward, so as to jointly complete the pushing action of the plate. In this process, one end of the lifting transmission rod 35 is in contact with the pushing plate 38, but only slides along the horizontal contact surface on the other side of the pushing plate 38, and does not rotate around the hinge point, so it will not drive the lifting plate 36 to realize the lifting action, and its state corresponds to Figure 4 The middle right upper part flow.

[0039] The pushing plate 38 is pushed to the lifting plate 36, and the lifting plate 36 is lifted to the position above the plate to be bent.

[0040] After the plate pushing action is completed, the driving assembly 31 maintains power output, and the other transmission wheel 34 drives one end of the lifting transmission rod 35 through the guide groove 341 of the transmission wheel 34, and the other end of the lifting transmission rod 35 slides along the track of the guide groove 341, so that the lifting transmission rod 35 rotates around the hinge point. The other end of the lifting transmission rod 35 drives the lifting plate 36 to slide upward along the vertical guide surface on one side of the pushing plate 38, and synchronously drives the pushing plate 391 to vertically rise, until it moves to the upper region of the plate to be bent, and completes the lifting reset. In this stage, the pushing transmission rod 37 does not rotate around the hinge point, so the pushing plate 38 does not displace in the horizontal direction, and its state corresponds to Figure 4 The middle right lower part flow.

[0041] The pushing plate 38 is pushed to the lifting plate 36, and the lifting plate 36 is lifted to the position above the plate to be bent.

[0042] After the lifting reset is completed, the transmission shaft 33 continues to drive the transmission wheel 34 to rotate, and the transmission wheel 34 drives the pushing transmission rod 37 to rotate again through the guide groove 341. The other end of the pushing transmission rod 37 drives the pushing plate 38 to slide in the horizontal direction away from the plate, and the pushing plate 391 is synchronously reset with the pushing plate 38, and the horizontal reset of the pushing component is completed. In this process, one end of the lifting transmission rod 35 still slides along one side of the pushing plate 38, and the lifting plate 36 remains in a fixed state, and its state corresponds to Figure 4 The middle left lower part flow.

[0043] The pushing plate 38 is pushed to the lifting plate 36, and the lifting plate 36 is lifted to the position above the plate to be bent.

[0044] After the horizontal reset of the pushing component, the other transmission wheel 34 again pulls the lifting transmission rod 35 to rotate through the guide groove 341, and the lifting transmission rod 35 drives the lifting plate 36 to slide downward along the vertical guide surface on one side of the pushing plate 38, and the top pushing rod 39 and the pushing cross plate 391 vertically descend synchronously with the pushing plate 38, and finally return to the initial feeding position on one side of the plate material to be sent, preparing for the next pushing action. In this stage, the pushing transmission rod 37 remains stationary, and the pushing plate 38 does not slide horizontally, and its state corresponds to Figure 4 The upper left part of the flow.

[0045] Through the reciprocating feeding of the automatic feeding assembly 3, the cyclic feeding operation can be completed without the cooperation of a group of lifting assemblies and a group of pushing assemblies, the mechanical transmission structure and the electric control coordination module required by the multi-component linkage are reduced, the overall layout of the feeding system is more compact, not only reduces the floor area of the equipment in the production workshop, but also provides convenience for subsequent equipment installation, debugging, daily maintenance and maintenance. Maintenance personnel do not need to repeatedly check linkage faults among multiple components, but can directly focus on the core components of the automatic feeding assembly 3 for maintenance, greatly shortening the maintenance working hours and improving the equipment operation and maintenance efficiency.

[0046] In addition, the single reciprocating operation of the automatic feeding assembly 3 can ensure that the starting point and the ending point position of each feeding remain highly uniform through the preset mechanical limit and electric control calibration program, reduce the error accumulation risk caused by multi-component cooperation from the source, and further guarantee the stability and accuracy of the feeding link.

[0048] In the embodiment, after the mechanical arm places the plate to be bent on one side of the automatic feeding assembly 3, the automatic feeding assembly 3 accurately pushes the plate to the bottom end of the conveying assembly 6, and resets immediately after the pushing action is completed, so as to prepare for the next feeding process. In this process, the visual monitoring assembly 4 captures and records the spatial position parameters of the plate in real time, and synchronously transmits the complete spatial data to the information processing terminal 5. Based on the received spatial position data of the plate, the information processing terminal 5 accurately analyzes through a preset algorithm, and respectively issues corresponding control instructions to the conveying assembly 6 and the bending assembly 2. Subsequently, the plate smoothly slides into the inside of the conveying frame 61, another driving motor built in the conveying assembly 6 starts to drive the conveying rollers 62 to rotate at a uniform speed according to the instruction speed, so as to accurately convey the plate to the specified processing position of the bending groove 63. Then, the electric telescopic rods 21 of the bending assembly 2 extend according to the preset stroke, drive the transmission frame 22 and the pressing plate 23 to vertically descend, the pressing plate 23 applies stable pressure to the preset processing point of the plate, and the accurate pressing and bending operation is completed.

[0049] The whole process does not need manual direct participation in the bending core link, fundamentally avoids the safety risks that may be faced in the manual operation process such as mechanical extrusion and plate springback, and significantly improves the safety protection level and overall operation efficiency of the bending process. Further, through the collaborative operation of the automatic equipment and the intelligent control system, the individual difference influence brought by manual operation can be effectively eliminated, the bending angle and size precision of each plate are kept highly consistent, the product failure rate is greatly reduced, and the production quality stability is improved.

[0050] Embodiment three: according to Figures 1-9 As shown in the figure, the metal plate bending machine based on unmanned operation in the application includes a processing table 1, the middle part of the processing table 1 is fixedly installed with a No. 1 mounting bracket 11, the inside of the No. 1 mounting bracket 11 is fixedly connected with a bending assembly 2, the bending assembly 2 applies pressure to the processing point of the plate to make it bend, the bending assembly 2 is provided below, the side of the processing table 1 is provided with an automatic feeding assembly 3, the automatic feeding assembly 3 and the conveying assembly 6 cooperate to transmit the plate to the below of the bending assembly 2, the side of the No. 1 mounting bracket 11 is provided with a visual monitoring assembly 4, the signal output end of the visual monitoring assembly 4 is connected with an information processing terminal 5, the signal output end of the information processing terminal 5 is connected with the signal input end of the bending assembly 2, the conveying assembly 6 and the automatic feeding assembly 3, the bending assembly 2 includes two groups of electric control telescopic rods 21, a transmission frame 22 and a pressing plate 23, the driving end of the two groups of electric control telescopic rods 21 is fixedly connected with one end of the transmission frame 22, the pressing plate 23 is fixedly connected with the other end of the transmission frame 22, the two sides of the transmission frame 22 are fixedly connected with sliding blocks 221, the inside of the No. 1 mounting bracket 11 is fixedly connected with sliding rails 111, the sliding blocks 221 are slidingly connected with the outside of the sliding rails 111, the side of the processing table 1 is fixedly connected with an auxiliary conveyor 7, the auxiliary conveyor 7 includes a mounting groove 71 and a plurality of conveying rollers 72, the plurality of conveying rollers 72 are rotatably connected with the inside of the mounting groove 71, and the outside of the plurality of conveying rollers 72 is movably sleeved with flexible sleeves.

[0051] In this embodiment, during the bending operation execution stage, the electric control telescopic rod 21 drives the transmission frame 22 and the pressing plate 23 to complete the precise height adjustment according to the control instruction issued by the information processing terminal 5.
