Description

Technical Field

[0001] This utility model relates to the field of forging production technology, specifically to a forging processing pick-up device. Background Technology

[0002] Forgings are workpieces or blanks obtained by forging and deforming metal billets. By applying pressure to the metal billet, plastic deformation is caused, which can change its mechanical properties. In the forging process, a forging removal device is usually used to pick up and put down the forgings.

[0003] As in the patent with publication number CN222242496U, the part-retrieving platform first enters the interior of the ring forging, then the electric telescopic rod is activated to drive the inflatable suction cups to move outward. The inner end of the forging is limited by the inflation of multiple inflatable suction cups. Then the pad is unfolded, and finally the inflatable suction cups are slowly deflated, which can reduce the clamping force and allow the forging to slide onto the surface of the pad and finally fall onto the surface of the pad. At this time, when transporting the forging, the clamping time and force of the clamping device can be reduced, which can play the role of limiting the forging. However, this structure relies on gravity to allow the forging to slide down by slowly releasing air, which is relatively unstable. Due to uneven friction on the contact surface, the inner wall of the forging is not absolutely smooth or has oxide scale, it cannot slide down smoothly. Moreover, at a certain critical point, the friction is instantly overcome, and the forging will slam onto the pad. For forgings with precision or machined surfaces, this impact can cause bumps, scratches or even deformation. Therefore, a forging removal device for forging processing is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a part-removing device for forging processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a forging processing pick-up device, comprising a base, a frame slidably mounted on the top of the base, a movable frame slidably mounted on the surface of the frame, and a first hydraulic cylinder fixedly mounted on the top of the movable frame; The bottom of the mobile frame is provided with a gripper mechanism, which includes a bracket, a sliding rod, two connecting rods, and two grippers. The bent end of the connecting rod is rotatably connected to the inner side of the bracket, the grippers are fixedly connected to one end of the connecting rod, and the sliding rod is slidably connected to the inside of the sliding grooves of the two connecting rods. A support mechanism is provided at the bottom of the frame and near the gripper mechanism.

[0006] Preferably, the connecting rod has a V-shaped structure with a large opening, and the two connecting rods are staggered.

[0007] Preferably, the gripper mechanism further includes a lifting seat and a second hydraulic cylinder; The lifting seat is fixedly connected to the output end of the first hydraulic cylinder, and the second hydraulic cylinder is fixedly installed on one side of the bottom of the lifting seat.

[0008] Preferably, the bracket is fixedly connected to the other side of the bottom of the lifting seat, and the output end of the second hydraulic cylinder is fixedly connected to the slide rod.

[0009] Preferably, the support mechanism includes a fixed housing, a connecting frame, a motor, a tray, a lifting frame, and a spring; The fixed housing is fixedly connected to the bottom of the frame, the connecting frame is fixedly connected to the outside of the lifting seat, the lifting frame is slidably connected to the inside of the fixed housing, the motor is fixedly installed on the outside of the lifting frame, the tray is rotatably connected to the inside of the lifting frame, and the spring is fixedly installed on the inside of the fixed housing.

[0010] Preferably, the output shaft end of the motor is fixedly connected to the tray, and the tray, when rotated to a horizontal position, is located below the gripper.

[0011] Preferably, the connecting frame is fixedly connected to the outer side of the lifting frame, and the spring is fixedly connected to the top of the lifting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the gripper mechanism causes the second hydraulic cylinder to drive one end of the two connecting rods to retract inward at the same time, thereby driving the two grippers to clamp the inner or outer wall of the forging smoothly and synchronously. This process is an active and controllable clamping force, thus avoiding the sudden slippage caused by uneven friction in the traditional structure. This support mechanism operates simultaneously with the downward movement of the gripper mechanism, which performs the clamping action. This allows the support tray, rotated to a horizontal position, to provide synchronous support or protection below the forging, forming a dynamic safety platform. This dual action of clamping and supporting ensures that the forging remains under control throughout the entire process of being clamped, moved, and lowered, thereby completely eliminating the risk described in the background art of "at a certain critical point, the frictional force is instantly overcome, and the forging crashes down."

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution for a forging processing pick-up device: a forging processing pick-up device includes a base 1, a frame 2 is slidably mounted on the top of the base 1, a movable frame 3 is slidably mounted on the surface of the frame 2, and a first hydraulic cylinder 4 is fixedly mounted on the top of the movable frame 3. The bottom of the movable frame 3 is provided with a gripper mechanism 5. The gripper mechanism 5 includes a bracket 502, a slide rod 505, two connecting rods 503 and two grippers 504. The bent end of the connecting rod 503 is rotatably connected to the inner side of the bracket 502. The grippers 504 are fixedly connected to one end of the connecting rod 503. The slide rod 505 is slidably connected to the inside of the sliding groove of the two connecting rods 503. A support mechanism 6 is provided at the bottom of the frame 2 and near the gripper mechanism 5; The gripper mechanism 5 also includes a lifting seat 501 and a second hydraulic cylinder 506; The lifting seat 501 is fixedly connected to the output end of the first hydraulic cylinder 4, and the second hydraulic cylinder 506 is fixedly installed on one side of the bottom of the lifting seat 501. The support mechanism 6 includes a fixed housing 601, a connecting frame 602, a motor 603, a tray 604, a lifting frame 605, and a spring 606; The fixed housing 601 is fixedly connected to the bottom of the frame 2, the connecting frame 602 is fixedly connected to the outside of the lifting seat 501, the lifting frame 605 is slidably connected to the inside of the fixed housing 601, the motor 603 is fixedly installed on the outside of the lifting frame 605, the tray 604 is rotatably connected to the inside of the lifting frame 605, and the spring 606 is fixedly installed on the inside of the fixed housing 601. Working principle: At the beginning of the device, the frame 2 is adjusted to a suitable height through its vertical sliding connection with the base 1. The moving frame 3 moves axially on the frame 2, driving the entire gripper mechanism 5 and the support mechanism 6 to move directly above the forging. At this time, the gripper mechanism 5 is in the open state (the distance between the two grippers 504 is relatively large), and the tray 604 in the support mechanism 6 is in the vertical state, making room for the lowering and picking up of the forging. When it is necessary to remove the forging, the first hydraulic cylinder 4 is activated, and its output end pushes the lifting seat 501 downward, thereby driving the entire gripper mechanism 5 to move downward, so that the gripper 504 enters the inner hole of the forging (such as a ring forging) or reaches the appropriate clamping position on its outer wall. Subsequently, the second hydraulic cylinder 506 is activated, and the piston rod of the second hydraulic cylinder 506 extends, pushing the slide rod 505 to move along the sliding grooves on the two V-shaped connecting rods (503). Since the bent ends of the two connecting rods 503 are fixed by the bracket 502, the linear motion of the slide rod 505 is converted into the relative rotation of the two connecting rods 503 around their axis, so that one end of the two connecting rods 503 (the end where the gripper 504 is installed) simultaneously retracts inward, thereby driving the two grippers 504 to move inward. 4. The inner or outer wall of the forging is clamped smoothly and synchronously. This process is an active and controllable clamping force, which completely avoids sudden slippage caused by uneven friction. At the same time as the gripper mechanism 5 moves down and performs the clamping action, the support mechanism 6 also starts to move. Since the connecting frame 602 is fixed on the lifting seat 501, when the lifting seat 501 is driven down by the first hydraulic cylinder 4, the connecting frame 602 will synchronously drive the lifting frame 605 to slide down in the fixed housing 601. After the lifting frame 605 moves down a certain distance, the motor 603 fixedly installed on it starts and drives the tray 604 to rotate to a horizontal state. At this time, the horizontally extended tray 604 is located directly below the clamped forging and maintains slight contact with the bottom of the forging to provide support. Then, the output end of the first hydraulic cylinder 4 is reversed to slowly lift the lifting seat 501 and the clamped forging. At the initial moment of lifting, even if the static friction between the gripper 504 and the forging changes slightly due to vibration or other reasons, the forging will not fall or be impacted because its bottom has been steadily supported by the horizontal tray 604.

[0017] Please refer to this carefully. Figure 3 The connecting rod 503 has a V-shaped structure with a large opening, and the two connecting rods 503 are staggered.

[0018] In this embodiment, one end of the two connecting rods 503 (the end where the clamping jaws 504 are mounted) retracts inward simultaneously, thereby driving the two clamping jaws 504 to smoothly and synchronously clamp the inner or outer wall of the forging.

[0019] Please refer to this carefully. Figure 2The bracket 502 is fixedly connected to the other side of the bottom of the lifting seat 501, and the output end of the second hydraulic cylinder 506 is fixedly connected to the slide rod 505.

[0020] In this embodiment: by activating the second hydraulic cylinder 506, the piston rod of the second hydraulic cylinder 506 extends, pushing the slide rod 505 to move along the grooves on the two V-shaped connecting rods (503).

[0021] Please refer to this carefully. Figure 4 The output shaft end of the motor 603 is fixedly connected to the tray 604, and the tray 604, which is rotated to a horizontal position, is located below the gripper 504.

[0022] In this embodiment, the horizontally extended tray 604 is positioned directly below the clamped forging, maintaining slight contact with the bottom of the forging to provide support. This design ensures that there is a safety net underneath the forging after it has been fully lifted.

[0023] Please refer to this carefully. Figure 4 The connecting frame 602 is fixedly connected to the outer side of the lifting frame 605, and the spring 606 is fixedly connected to the top of the lifting frame 605.

[0024] In this embodiment: during the process of the lifting frame 605 being driven to move up and down by the connecting frame 602, the lifting frame 605 will exert force on the spring 606, and the spring 606 will stretch or contract accordingly.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
