Description

Technical Field

[0001] This utility model belongs to the field of parts processing technology, specifically relating to a parts bending and unloading mechanism. Background Technology

[0002] A parts bending and stripping mechanism is a specialized piece of equipment used in the processing of metal parts. It is primarily used to bend and shape metal materials and then effectively strip them. It is commonly used in equipment such as stamping presses and bending machines to improve production efficiency and processing accuracy.

[0003] Chinese Patent Publication No. CN212822236U discloses a bending device for processing hardware parts, including a bending device body and an asynchronous motor. The surface of the bending device body has a bending groove, and a pressing rod is hinged to the surface of the bending device body. A rotating block is hinged to the front of the pressing rod, and a locking block is fixedly connected to the surface of the rotating block. The bending device body has a locking groove, and a support base is fixedly connected to the right side of the bending device body. The top of the support base is fixedly connected to the asynchronous motor. This patent includes a turntable and a connecting rod. The asynchronous motor drives the turntable to rotate, and the turntable drives the connecting rod to perform piston-like motion on the pressing block, causing the pressing block to slide up and down in the groove, thereby quickly pressing the part in the bending groove to bend the part. Through pressing and a water tank, the pressing rod is pulled, causing the pressing rod to press an air chamber. The air chamber adds air to the water tank, causing the coolant in the water tank to spray out from the nozzle, thereby reducing the heat at the bending point.

[0004] However, this bending device does not have an automatic unloading mechanism for hardware parts. In actual operation, workers need to manually remove the bent parts, which poses a certain safety hazard. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a part bending and unloading mechanism to solve at least one of the above problems, thereby solving the problem that parts cannot be automatically unloaded after bending by the bending mechanism and require manual operation in the prior art. It realizes automatic unloading of bent hardware parts after bending, saving operating costs.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] The technical solution of this utility model is to provide a part bending and unloading mechanism, which includes a bending component and an unloading component;

[0008] The bending assembly includes a cylinder, a bending head, and a bending table; the cylinder is positioned directly above the bending table, and the cylinder output end is fixedly connected to the bending head; the shape of the bending head matches the shape of the bending table.

[0009] The output end of the cylinder is also fixed with a connecting plate. The connecting plate is connected to one side of the bending table through a stripping assembly. When the output end of the cylinder retracts upward, the stripping assembly supports one side of the bending table, allowing the bent part to come out on its own.

[0010] Furthermore, the stripping assembly includes a threaded rod, a movable plate, a connecting plate, gears, and a toothed plate;

[0011] The connecting plate is connected to the bending table and the moving plate at both ends respectively; the moving plate is sleeved on the outside of the threaded rod; a gear is keyed to one end of the threaded rod, and the gear meshes with the gear plate.

[0012] Furthermore, the inner side of the movable plate is provided with threads, and the threads on the inner side of the movable plate mesh with the threads on the surface of the threaded rod. When the threaded rod rotates, the movable plate slides along the threaded rod.

[0013] Furthermore, the two ends of the connecting plate are respectively hinged to the bending table and the moving plate.

[0014] Furthermore, the toothed plate slides up and down along the direction of movement of the cylinder output end.

[0015] Furthermore, a counterweight is fixedly installed at the bottom of the toothed plate, and the bottom of the connecting plate is located directly below the counterweight.

[0016] Furthermore, the distance that the cylinder output end extends is greater than the distance between the connecting plate and the counterweight.

[0017] Furthermore, after the bending head of the cylinder output end extends downward and bends, the output end retracts upward, the connecting plate moves upward and lifts the counterweight, causing the toothed plate to slide upward.

[0018] Furthermore, the bending table is installed on the upper part of the table surface, and a guide plate is fixedly installed at the bottom end of the bending table. A guide groove is opened on the inner side of the table surface, and the guide plate is slidably connected to the guide groove.

[0019] Furthermore, the threaded rod is rotatably connected inside the table, and the movable plate is slidably connected inside the table.

[0020] Furthermore, the gear meshes with the toothed plate, the threaded rod meshes with the moving plate, the moving plate, the connecting plate and one side of the bending table are hinged in sequence, and the guide plate is slidably connected to the guide groove. Therefore, during the sliding process, the toothed plate drives the gear to rotate through the meshing action, which in turn drives the threaded rod to rotate. The threaded rod drives the moving plate to slide inside the table through the meshing connection. During the sliding process, the moving plate cooperates with the connecting plate to drive the bending table and the guide plate to slide along the guide groove, thereby lifting one side of the bending table and automatically unloading the hardware parts processed inside the bending table.

[0021] Furthermore, the cylinder is mounted on the top plate, the top plate is mounted on the top of the connecting column, and the connecting column is fixedly installed on the top of the platform.

[0022] Furthermore, a horizontal plate is fixedly installed at the bottom of the connecting plate, and the horizontal plate is located directly below the counterweight.

[0023] Furthermore, a pressure sensor is installed at the contact position between the bending head and the part. The start and stop of the cylinder are controlled by the controller, and the pressure sensor is electrically connected to the controller. When the bending pressure is detected to reach the set critical value, the controller commands the cylinder to stop pressing down and bending, and the cylinder output end retracts upward, thereby causing one side of the bending table to tilt upward, and the bent part can be removed.

[0024] Furthermore, this invention is mainly used for bending and stripping precision hardware parts.

[0025] Furthermore, the above-mentioned parts bending and unloading mechanism is used as follows: place the hardware parts on the bending table, start the cylinder, and the cylinder output end drives the bending head and connecting plate to move downward to bend. After the bending operation is completed, the cylinder output end drives the bending head and connecting plate to move upward, and the connecting plate drives one side of the bending table to shift upward, so that the bent hardware parts are automatically unloaded. During the next bending, the cylinder drives the connecting plate to descend, so that the bending table is reset.

[0026] Furthermore, the specific usage method includes: first, placing the hardware parts on the bending table, then starting the cylinder and driving the bending head down to bend the hardware parts; next, starting the cylinder and driving the bending head up, which in turn drives the connecting plate up, thereby driving the horizontal plate up; finally, the horizontal plate pushes the counterweight upward and drives the toothed plate to slide upward, which drives the gear to rotate under meshing action, thereby driving the threaded rod to rotate; under the action of the thread, the moving plate can slide along the table surface, thereby driving the connecting plate to change its angle and position; during this process, under the action of the connecting plate, the bending table and the guide plate will slide along the direction of the guide groove, thereby automatically unloading the bent hardware parts; then, when the cylinder drives the horizontal plate down, the toothed plate will slide down under the action of the counterweight, thereby allowing the bending table to reset.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. This utility model provides a guide plate, guide groove, threaded rod, moving plate, connecting plate, gear, toothed plate, counterweight, and connecting plate below the bending table. After the bending operation is completed, as the cylinder output end moves upward, the unloading assembly can drive the bending table and guide plate to move along the guide groove through a series of meshing connections, hinges, and other connection methods under the action of the transmission mechanism. This allows the bent hardware parts to be automatically unloaded, reducing safety hazards and eliminating the need for an additional power source, making it highly practical.

[0029] 2. This utility model, by setting a pressure sensor on the top of the bending head, allows the controller to instruct the cylinder to stop pressing down when the pressure reaches the set value during the bending process, making the bending force of the bending head on the hardware parts controllable and enhancing the precision of the hardware parts during the bending process.

[0030] 3. This utility model has a counterweight block set below the toothed plate, so that after the parts are automatically unloaded, the bending table can slowly return to its original position under the gravity of the counterweight block, thereby performing the bending operation of the next part, saving operating costs and simplifying the bending steps.

[0043] Please see again Figure 3 and Figure 4The unloading assembly includes a guide plate 7, a guide groove 8, a threaded rod 9, a moving plate 10, a connecting plate 11, a gear 12, a toothed plate 13, and a counterweight 14. The bottom end of the bending table 6 is fixedly installed with the guide plate 7, and the inner side of the table surface 1 is provided with the guide groove 8. The guide plate 7 and the guide groove 8 are slidably connected. The two ends of the connecting plate 11 are respectively hinged to the bending table 6 and the moving plate 10. The moving plate 10 is sleeved on the outside of the threaded rod 9. The inner side of the moving plate 10 is provided with threads, and the threads on the inner side of the moving plate 10 mesh with the threads on the surface of the threaded rod 9. When the threaded rod 9 rotates, the moving plate 10 slides back and forth along the threaded rod 9 on the inner side of the table surface 1. One end of the threaded rod 9 is keyed to the gear 12, and the gear 12 meshes with the toothed plate 13. The bottom of the toothed plate 13 is fixedly installed with the counterweight 14, and the bottom of the connecting plate 15 is located directly below the counterweight 14.

[0044] Please see again Figure 2 The output end of the cylinder 4 is also fixed with a connecting plate 15. The connecting plate 15 is connected to one side of the bending table 6 through a stripping assembly. When the output end of the cylinder 4 retracts upward, the stripping assembly supports one side of the bending table 6, so that the bent part comes out on its own.

[0045] Please see again Figure 3 The threaded rod 9 is rotatably connected inside the table 1, and the moving plate 10 is slidably connected inside the table 1; the toothed plate 13 slides up and down inside the table 1 along the movement direction of the output end of the cylinder 4; the distance extended by the output end of the cylinder 4 is greater than the distance between the connecting plate 15 and the counterweight 14; after the bending head 5 of the output end of the cylinder 4 extends downward and bends, the output end retracts upward, the connecting plate 15 moves upward and lifts the counterweight 14, so that the toothed plate 13 slides upward.

[0046] Please see again Figure 3 The gear 12 meshes with the toothed plate 13, and the threaded rod 9 meshes with the moving plate 10. The moving plate 10, the connecting plate 11, and one side of the bending table 6 are hinged in sequence. The guide plate 7 is slidably connected to the guide groove 8. Therefore, during the sliding process, the toothed plate 13 drives the gear 12 to rotate through the meshing action, which in turn drives the threaded rod 9 to rotate. The threaded rod 9 drives the moving plate 10 to slide inside the table 1 through the meshing connection. During the sliding process, the moving plate 10 cooperates with the connecting plate 11 to drive the bending table 6 and the guide plate 7 to slide along the guide groove 8, thereby lifting one side of the bending table and automatically unloading the hardware parts processed inside the bending table 6.

[0047] The bending head is equipped with a piezoresistive pressure sensor at the contact position with the part. The start and stop of the cylinder are controlled by the controller, and the pressure sensor is electrically connected to the controller. When the bending pressure is detected to reach the set critical value, the controller commands the cylinder to stop pressing down and bending, and the cylinder output end retracts upward, thereby causing one side of the bending table to tilt upward, and the bent part can be removed.
