Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing equipment, in particular to a feeding mechanism and a sheet metal processing and bending equipment. Background Technique

[0002] A sheet metal bending machine is a machine that can bend workpieces into shape. It mainly consists of a bracket, a workbench and a clamping plate. Its function is to press the sheet into various shaped parts according to the process requirements. The sheet metal bending machine can meet the needs of various workpieces by replacing the bending die.

[0003] In the prior art, in order to avoid manual handling of sheet metal parts by workers onto the workbench for bending, generally a conveyor belt is used to feed the sheet metal parts, convey them to the bending equipment, and then transfer the sheet metal parts from the conveyor belt to the bending equipment for bending processing operations through a powerful pneumatic suction cup.

[0004] However, during the process of transporting and feeding the sheet metal parts on the conveyor belt, due to problems such as placement or vibration, the position of the sheet metal parts will shift during the feeding process on the conveyor belt, resulting in the inability to ensure accurate placement of the workpiece at the bending mechanism of the bending equipment when the pneumatic suction cup sucks the sheet metal parts. Therefore, manual adjustment is still required, which reduces the processing quality and processing efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide a feeding mechanism and a sheet metal processing and bending equipment to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A feeding mechanism includes a feeding mechanism body. A controller is arranged on one side of the feeding mechanism body. The controller is fixedly connected to the conveyor belt on one side. A cylinder is arranged on one side of the conveyor belt.

[0007] The output end of the cylinder is provided with a T-shaped block. A rotating plate is installed on the upper side of the T-shaped block. One end of the rotating plate is fixedly sleeved with a connecting shaft. The upper end of the connecting shaft is sleeved with a driven rod. One end of the driven rod is installed with a pushing plate.

[0008] Preferably, the controller is electrically connected to the conveyor belt. A limiting plate is fixedly connected to the upper surface of the conveyor belt. A moving object sensor is arranged on one side of the limiting plate.

[0009] Preferably, a set of two limiting plates and moving object sensors are arranged symmetrically about the central plane of the conveyor belt. The moving object sensor is electrically connected to the controller.

[0010] Preferably, the moving object sensor is electrically connected to the controller. The controller is electrically connected to the cylinder. A connecting seat is fixedly installed on one side of the cylinder. The moving object sensor is fixedly connected to the pushing plate.

[0011] Preferably, one side of the connecting seat is rotatably connected to the fixing plate through a fixing pin, and one side of the fixing plate is fixedly connected to the conveyor belt. A support plate is fixedly connected to the upper surface of the fixing plate.

[0012] Preferably, a ball eye joint is fixedly installed at the output end of the cylinder. The ball eye joint is rotatably connected to the T-shaped block through a connecting pin, and the T-shaped block is rotatably connected to the rotating plate through a limiting post.

[0013] Preferably, one end of the connecting shaft is fixedly sleeved in the rotating plate, and the other end of the connecting shaft is rotatably sleeved in the support plate. One end of the driven rod is fixedly sleeved on the connecting shaft, and the other end of the driven rod is rotatably connected to the pushing plate through a fixing shaft. A protective block is fixedly connected to one side of the pushing plate.

[0014] A sheet metal processing bending device includes the above-mentioned feeding mechanism.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] For the feeding mechanism proposed by the present utility model, the sheet metal part enters the conveyor belt from the side where the controller is installed for feeding. When the workpiece is about to be separated from the conveyor belt and is adsorbed by the pneumatic suction cup assembly for feeding, when the moving object sensor detects that there is a workpiece moving on the conveyor belt, at this time, a signal will be transmitted to the controller, and the controller will control the cylinder to contract. The contraction of the cylinder drives the T-shaped block to move through the ball eye joint installed at its output end under the connection of the connecting pin, so that the T-shaped block moves towards the side close to the conveyor belt. One end of the T-shaped block is rotatably connected to the rotating plate through a limiting post, and the other end of the rotating plate is fixedly sleeved with a connecting shaft. Thus, driven by the T-shaped block, one end of the rotating plate rotates around the limiting post, and the other end of the rotating plate drives the driven rod to rotate through the connection of the connecting shaft, so that the end of the driven rod far from the connecting shaft moves towards the direction close to the conveyor belt, and then drives the pushing plate to move towards the central plane direction of the conveyor belt through the rotational connection with the fixing shaft, so that the protective block on one side of the pushing plate pushes the workpiece to move. Finally, under the pushing action of a group of pushing plates, the position of the sheet metal part is adjusted so that it is always located in the middle of the conveyor belt, facilitating the re-adsorption and feeding by the pneumatic suction cup assembly, avoiding the trouble of manually adjusting the feeding position of the workpiece, and improving the processing efficiency and processing quality.

[0022] In order to clearly and completely describe the purpose, technical solution of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some embodiments of the present utility model, rather than all embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: including a feeding mechanism body 1, a controller 2 is arranged on one side of the feeding mechanism body 1, the controller 2 is fixedly connected to a conveyor belt 3 on one side, a cylinder 4 is arranged on one side of the conveyor belt 3, a T-shaped block 5 is arranged at the output end of the cylinder 4, a rotating plate 6 is installed on the upper side of the T-shaped block 5, a connecting shaft 7 is fixedly sleeved at one end of the rotating plate 6, a driven rod 8 is sleeved on the upper end of the connecting shaft 7, and a pushing plate 9 is installed at one end of the driven rod 8.

[0025] The sheet metal parts enter the conveyor belt 3 from the side where the controller 2 is installed for feeding. When the workpiece is about to be separated from the conveyor belt 3 and is adsorbed by the pneumatic suction cup assembly for feeding, by the contraction of the cylinder 4, the cylinder 4 drives the T-shaped block 5 to move towards the side close to the conveyor belt 3, thereby driving the rotating plate 6 to rotate towards the direction close to the conveyor belt 3. The rotating plate 6 drives the driven rod 8 to rotate towards the direction close to the conveyor belt 3 through the connection of the connecting shaft 7, and further indirectly drives the pushing plate 9 to move towards the central plane direction of the conveyor belt 3. There is a set of pushing plates 9, so that the two pushing plates 9 move towards each other, and then the pushing plates 9 are in contact with the side wall of the workpiece, so that the position of the workpiece is always in the middle of the conveyor belt 3, thus facilitating the accurate positioning of the sheet metal parts by the pneumatic suction cup assembly for picking up materials and avoiding the trouble of manual adjustment.

[0026] Embodiment 2

[0027] On the basis of the first embodiment, the controller 2 is electrically connected to the conveyor belt 3. A limiting plate 10 is fixedly connected to the upper surface of the conveyor belt 3. A moving object sensor 11 is arranged on one side of the limiting plate 10. One set of the limiting plate 10 and the moving object sensor 11, with a total of two, are symmetrically arranged with respect to the central plane of the conveyor belt 3. The moving object sensor 11 is electrically connected to the controller 2.

[0028] The conveyor belt 3 is controlled by the controller 2. A limiting plate 10 is fixedly connected to the upper surface of the conveyor belt 3. Under the limiting action of the limiting plate 10, the sheet metal part is prevented from deviating from the conveyor belt 3 during the feeding process. The moving object sensor 11 fixedly installed on one side of the pushing plate 9 facilitates the pushing action of the pushing plate 9 when the workpiece moves near the pushing plate 9, so as to ensure the position adjustment of each workpiece.

[0029] Embodiment Three

[0030] On the basis of the second embodiment, the moving object sensor 11 is electrically connected to the controller 2, and the controller 2 is electrically connected to the cylinder 4. A connecting seat 12 is fixedly installed on one side of the cylinder 4. The moving object sensor 11 is fixedly connected to the pushing plate 9. One side of the connecting seat 12 is rotatably connected to the fixing plate 13 through a fixing pin 14. One side of the fixing plate 13 is fixedly connected to the conveyor belt 3. A supporting plate 15 is fixedly connected to the upper surface of the fixing plate 13. A ball eye joint 16 is fixedly installed at the output end of the cylinder 4. The ball eye joint 16 is rotatably connected to the T-shaped block 5 through a connecting pin 17. The T-shaped block 5 is rotatably connected to the rotating plate 6 through a limiting column 18. One end of the connecting shaft 7 is fixedly sleeved in the rotating plate 6, and the other end of the connecting shaft 7 is rotatably sleeved in the supporting plate 15. One end of the driven rod 8 is fixedly sleeved on the connecting shaft 7, and the other end of the driven rod 8 is rotatably connected to the pushing plate 9 through a fixing shaft 19. A protective block 20 is fixedly connected to one side of the pushing plate 9.

[0031] When the moving object sensor 11 detects that a workpiece is moving on the conveyor belt 3, it will transmit a signal to the controller 2 at this time. The controller 2 will control the cylinder 4 to contract. The contraction of the cylinder 4 drives the T-shaped block 5 to move under the connection action of the fish-eye joint 16 installed at its output end and the connecting pin 17, so that the T-shaped block 5 moves toward the side close to the conveyor belt 3. The T-shaped block 5 is rotatably connected to one end of the rotating plate 6 through the limit post 18. The other end of the rotating plate 6 is provided with a connecting shaft 7 through a fixed sleeve. Thus, driven by the T-shaped block 5, one end of the rotating plate 6 rotates around the limit post 18, and the other end of the rotating plate 6 drives the driven rod 8 to rotate through the connection action of the connecting shaft 7. As a result, the end of the driven rod 8 away from the connecting shaft 7 moves toward the direction close to the conveyor belt 3, and then drives the pushing plate 9 to move toward the central plane direction of the conveyor belt 3 through the rotational connection with the fixed shaft 19, so that the protective block 20 on one side of the pushing plate 9 pushes the workpiece to move. Finally, under the pushing action of a group of pushing plates 9, the position of the sheet metal part is adjusted so that it is always located in the middle of the conveyor belt 3, which is convenient for the pneumatic suction cup assembly to adsorb and load the material, and avoids the trouble of manually adjusting the position of the workpiece.

[0032] During actual use, the sheet metal part enters the conveyor belt 3 from the side where the controller 2 is installed for feeding. When the workpiece is about to be separated from the conveyor belt 3 and is adsorbed and loaded by the pneumatic suction cup assembly, when the moving object sensor 11 detects that a workpiece is moving on the conveyor belt 3, it will transmit a signal to the controller 2 at this time. The controller 2 will control the cylinder 4 to contract. The contraction of the cylinder 4 drives the T-shaped block 5 to move under the connection action of the fish-eye joint 16 installed at its output end and the connecting pin 17, so that the T-shaped block 5 moves toward the side close to the conveyor belt 3. The T-shaped block 5 is rotatably connected to one end of the rotating plate 6 through the limit post 18. The other end of the rotating plate 6 is provided with a connecting shaft 7 through a fixed sleeve. Thus, driven by the T-shaped block 5, one end of the rotating plate 6 rotates around the limit post 18, and the other end of the rotating plate 6 drives the driven rod 8 to rotate through the connection action of the connecting shaft 7. As a result, the end of the driven rod 8 away from the connecting shaft 7 moves toward the direction close to the conveyor belt 3, and then drives the pushing plate 9 to move toward the central plane direction of the conveyor belt 3 through the rotational connection with the fixed shaft 19, so that the protective block 20 on one side of the pushing plate 9 pushes the workpiece to move. Finally, under the pushing action of a group of pushing plates 9, the position of the sheet metal part is adjusted so that it is always located in the middle of the conveyor belt 3, which is convenient for the pneumatic suction cup assembly to adsorb and load the material again, and avoids the trouble of manually adjusting the feeding position of the workpiece, improving the processing efficiency and processing quality.
