Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically a hydraulic stamping device that facilitates loading and unloading. Background Technology

[0002] Stamping is a process in which external force is applied to metal parts such as sheet metal, strip metal, tubing, and profiles using a press and dies, causing plastic deformation or separation to obtain workpieces of the required shape and size. Flanging of stamped parts refers to the stamping process of using dies to turn the edges of holes or outer edges of workpieces into vertical straight edges. This process is very common in metal processing and is used to increase the strength and rigidity of workpieces or to meet specific assembly requirements. Because non-standard parts vary in shape, size, and performance requirements, specific dies and stamping processes are required for their production.

[0003] Chinese Patent No. CN218425250U discloses a stamping device that facilitates loading and unloading, including a worktable. Mounting plate A and mounting plate B are welded on the worktable. A loading mechanism is mounted on the worktable via mounting plate A, and a stamping mechanism is mounted on the worktable via mounting plate B. A feeding mechanism is provided at the lower end of the loading mechanism, and a conveyor belt is driven within the feeding mechanism. The conveyor belt is closely attached to the surface of the worktable.

[0004] The above technical solution has the following drawbacks: the above technical solution uses a collection box to collect the stamped workpiece. If the stamped workpiece is not properly buffered or supported when it falls into the collection box, it may be damaged due to impact or mutual squeezing. When the workpiece needs to be operated on for the next step, it cannot be operated continuously, which reduces the convenience. Utility Model Content

The back of the mounting plate is fixedly connected to the rear of the upper surface of the workbench. A through groove is opened in the middle of the mounting plate, and both ends of the lead screw are connected to the inside of the through groove. The output end of the motor is connected to the lead screw through a coupling. Nut one and nut two are respectively connected to the lead screw.

[0026] Example 1:

[0027] A hydraulic stamping device for easy loading and unloading includes a worktable 2 and a hydraulic mechanism 3 mounted above the worktable 2.

The loading and unloading mechanism includes a workpiece moving unit and a synchronous loading and unloading unit.

[0028] The synchronous loading and unloading unit includes a mounting plate 4, a motor 401, a lead screw 402, a first nut 403, a second nut 404, a first connecting rod 405, a second connecting rod 406, an air pump 601, a first connecting pipe 602, a connecting hose 603, a second connecting pipe 604, a suction cup 605, a movable seat 701, a slide 702, an electric push rod 703, and a gripper 8. The back of the mounting plate 4 is fixedly connected to the rear of the upper surface of the workbench 2, providing a mounting base for components such as the motor 401 and the lead screw 402, ensuring their stable operation. A through slot is opened in the middle of the mounting plate 4, and both ends of the lead screw 402 are connected inside the through slot. The output end of the motor 401 is connected to the lead screw 402 through a coupling. By realizing the forward and reverse rotation of the motor 401, the lead screw 402 is driven to rotate, realizing the reciprocating movement of the first connecting rod 405 and the second connecting rod 406.

[0029] Nut 1 403 and Nut 2 404 are respectively connected to the lead screw 402. The back sides of connecting rod 1 405 and connecting rod 2 406 are respectively slidably connected to the slide groove 702. The slide groove 702 is opened on the front side of the movable seat 701. The back side of the movable seat 701 is fixedly connected to the front side of the connecting plate. Nut 1 403 and Nut 2 404 are fixedly connected to the back side of the connecting plate. There are two electric push rods 703, and their output ends are respectively connected to the bottom of connecting rod 1 405 and connecting rod 2 406.

[0030] Example 2:

[0031] Based on Embodiment 1, the workpiece moving unit includes a support frame 1, a conveyor belt 101, a limiting block 102, a placement platform 103, a second support frame 5, and a second conveyor belt 501. Support frame 1 and second support frame 5 are fixedly connected to both sides of the worktable 2, providing support for conveyor belts 101 and 501 to ensure their stable operation. Conveyor belt 101 is located in the middle of support frame 1. The limiting block 102 is fixedly connected to the front and rear sides of the right side of conveyor belt 101, limiting the range of the workpiece and ensuring that the workpiece can accurately reach the designated position. The bottom of the placement platform 103 is fixedly connected to the bottom of the limiting block 102, and the bottom right side of the placement platform 103 overlaps the worktable 2, providing a temporary parking platform for the workpiece and facilitating the loading operation of the suction cup. Conveyor belt 501 is located in the middle of support frame 2. Both conveyor belt 101 and conveyor belt 2 501 are driven by variable frequency speed control motor 401, and the surfaces of conveyor belt 101 and conveyor belt 2 501 are provided with anti-slip stripes, which increases the friction between the workpiece and the conveyor belt and prevents the workpiece from slipping or moving.

[0032] The lifting assembly includes a placement frame 202, a cylinder 203, and a top plate 204. The placement frame 202 is fixedly connected to the top surface inside the worktable 2, providing support for the cylinder 203 and ensuring its stable operation. The cylinder 203 is located in the middle of the placement frame 202, and the bottom surface of the top plate 204 is connected to the output end of the cylinder 203, providing power to drive the top plate 204 to move up and down. The bottom of the lower mold 201 has a through hole, through which the top plate 204 lifts the workpiece.

[0033] Working principle: The synchronous loading and unloading unit drives the lead screw 402 to rotate via the motor 401, causing nuts 403 and 404 to move on the lead screw 402. When the motor 401 rotates forward, the connecting plate drives connecting rods 405 and 406 to move in one direction; when the motor 401 rotates in reverse, they move in the opposite direction. The suction cup 605 on connecting rod 405 can adsorb the workpiece, while the gripper 8 on connecting rod 406 can grasp the workpiece. The suction pump 601 provides suction to the suction cup 605, enabling it to stably adsorb the workpiece, while the gripper 8 adjusts the air pressure to clamp and release the workpiece.

[0034] After the workpiece completes the stamping process, cylinder 203 is activated, extending the cylinder and lifting the workpiece through the through hole at the bottom of the lower mold 201 via the top plate 204. Electric push rod 703 is then activated, causing connecting rod 405 and connecting rod 406 to descend. At this time, suction cup 605 adsorbs the workpiece, while gripper 8 holds it. Cylinder 203 retracts, and the top plate 204 descends.

[0035] Then, the electric push rod 703 drives the connecting rod 1 405 and the connecting rod 2 406 to rise, starts the motor 401, drives the connecting plate to move to the right, and then starts the electric push rod 703 to drive the connecting rod 1 405 and the connecting rod 2 406 to fall. Then the gripper 8 and the suction cup are released. At this time, the workpiece that has been adsorbed is placed in the lower mold 201, and the clamped workpiece is conveyed by the conveyor 2 501.

[0036] The workpiece moving unit achieves continuous workpiece transport via conveyor belt 101 and conveyor belt 501. Both conveyor belts are driven by variable frequency speed control motors 401, allowing speed adjustment to meet different production needs. Limit blocks 102 restrict the workpiece's movement range on conveyor belt 101, ensuring accurate arrival at the designated position. A placement table 103 provides a temporary parking platform for the workpiece, facilitating loading operations by the suction cups 605.
