Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamps for air hammers, and specifically discloses a forging flipping clamp for air hammers. Background Technology
[0002] Air hammer clamps are crucial tools in the forging process for securing and turning forgings, and their design directly impacts operational efficiency, forging quality, and operational safety. Most clamps employ a hinged design between the first and second clamp bodies, maintaining the clamping state through locking devices such as screws or springs. For example, a double-clamp hinge design connects the first and second clamp bodies via a hinge shaft. The clamping block surface is designed with a mating surface adapted to the forging's shape, such as an arc-shaped jaw. Clamping is achieved by applying pressure through the handle.
[0003] However, the manual gripping operation undoubtedly increases the workload of the operator. Manual pressure requires repeated adjustments of grip strength, especially when gripping heavy forgings. The operator needs to expend extra physical strength to counteract inertial forces, and prolonged forceful gripping will lead to a decrease in overall work efficiency. In addition, the forging needs to be flipped during the forging process. However, flipping the forging during manual gripping is very easy to cause the forging to slip or deviate in positioning due to manual operation coordination errors. It is impossible to guarantee the stability of the gripping and the accuracy of the forging. At the same time, the forging falling during manual gripping can easily cause safety hazards. Utility Model Content

Detailed Implementation
[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0027] This specific embodiment provides a forging flipping clamp for an air hammer, such as... Figures 1-6As shown, the device includes a handle 1 for easy gripping by the operator. A support rod 2 is connected to the top of the handle 1. The support rod 2 has a cylindrical structure. A first fastener 3 is mounted on the top of the support rod 2. The first fastener 3 also has a cylindrical structure. A second fastener 5 is arranged above the first fastener 3. A rotating shaft 4 is arranged between the upper bottom surface of the first fastener 3 and the lower bottom surface of the second fastener 5. A rotating platform 6 is rotatably connected to the rotating shaft 4. A fifth opening with a circular structure is opened at the bottom of the rotating platform 6. A thread is provided in the fifth opening. A connecting part 7 is fixedly connected to the top of the rotating platform 6.
[0028] The connecting part 7 has a first circular opening, and a support shaft 8 is fastened into the first opening. The support shaft 8 has a first protrusion 9 and a second protrusion 10 at each end, both of which are cylindrical. A first rotating arm 11 is rotatably connected to the first protrusion 9 via a bearing, and a second rotating arm 12 is rotatably connected to the second protrusion 10 via a bearing. A first clamping arm 13 is fastened to the first protrusion 9 and is positioned above the first rotating arm 11. On the inner side, a second clamping arm 14 is fastened to the second protrusion 10. The second clamping arm 14 is arranged on the inner side of the second rotating arm 12. Meanwhile, the first clamping arm 13 and the second clamping arm 14 are arranged above the first rotating arm 11 and the second rotating arm 12. A stop ring 22 is fixedly installed on both the first protrusion 9 and the second protrusion 10. The stop ring 22 is arranged on the outer side of the first rotating arm 11 and the second rotating arm 12 to prevent the first rotating arm 11 and the second rotating arm 12 from falling off the first protrusion 9 and the second protrusion 10.
[0029] A limiting part 15 is arranged between the first rotating arm 11 and the second rotating arm 12 near their ends. The limiting part 15 has a second opening with a circular structure and a thread inside the second opening. A fixed seat 16 is arranged between the first clamping arm 13 and the second clamping arm 14. The fixed seat 16 has a third opening with a circular structure, and a threaded rod 17 is rotatably installed in the third opening through a bearing. A handle 23 is installed at the end of the threaded rod 17 away from the fixed seat 16.
[0030] The threaded rod 17 and the limiting part 15 are connected by a threaded rotation. The operator can rotate the threaded rod 17 to make the limiting part 15 move along the direction of the threaded rod 17. The movement of the limiting part 15 causes the first rotating arm 11 and the second rotating arm 12, which are fastened to it, to rotate on the first protrusion 9 and the second protrusion 10. When the threaded rod 17 is rotated clockwise, the first rotating arm 11 and the second rotating arm 12 also rotate clockwise. At this time, the first rotating arm 11 and the second rotating arm 12 are clamped with the first clamping arm 13 and the second clamping arm 14. At the same time, when the threaded rod 17 is rotated counterclockwise, the first rotating arm 11 and the second rotating arm 12 rotate counterclockwise. At this time, the first rotating arm 11 and the second rotating arm 12 are loosened from the first clamping arm 13 and the second clamping arm 14.
[0031] A first clamping part 24 is fixedly installed between the first rotating arm 11 and the second rotating arm 12, and a second clamping part 25 is fixedly installed between the first clamping arm 13 and the second clamping arm 14. Both the first clamping part 24 and the second clamping part 25 are provided with grooves 26 for increasing friction. A first support column 27 and a second support column 28 for fixed support are provided between the first rotating arm 11 and the second rotating arm 12.
[0032] The support rod 2 is fastened with an anti-rotation part 18 near the first fastener 3. The anti-rotation part 18 consists of a square structure and two arc-shaped structures. The square structure has a fourth opening with a circular structure. The anti-rotation part 18 is fastened to the support rod 2 through the fourth opening. The top of the square structure of the anti-rotation part 18 has two arc-shaped structures symmetrically arranged along the support rod 2. The arc-shaped structures have a first screw hole 19 and a second screw hole 20 respectively. A knob screw 21 is rotatably connected in the first screw hole 19. The knob screw 21 is rotatably connected to the fifth opening at the bottom of the rotating platform 6. The knob screw 21 is used to fix the clamp and prevent the clamp from flipping. The operator can unscrew the knob screw 21 from the bottom of the rotating platform 6 and the first screw hole 19, and then rotate the rotating platform 6 to flip the clamp. After that, the knob screw 21 is screwed into the bottom of the rotating platform 6 and the second screw hole 20 to fix it and prevent the clamp from flipping again.
[0033] The working principle of this utility model is as follows:
[0034] Before use, the operator screws the threaded rod 17 counterclockwise using the handle 23. At this time, the limiting part 15 moves away from the fixed seat 16 on the threaded rod 17, and the first rotating arm 11 and the second rotating arm 12 rotate counterclockwise. The first clamping part 24 and the second clamping part 25 move away from each other, and the clamp is in a loose state. At the same time, the operator screws the knob screw 21 into the bottom of the rotating table 6 and the first screw hole 19 to fix it and prevent the clamp from flipping.
[0035] During use, the operator places the forging between the first clamping part 24 and the second clamping part 25, and then screws the threaded rod 17 clockwise again. This causes the limiting part 15 to move along the threaded rod 17 towards the fixed seat 16. The first rotating arm 11 and the second rotating arm 12 rotate clockwise, bringing the first clamping part 24 and the second clamping part 25 closer together. The clamps are in a clamping state, securing the forging. At the same time, the grooves 26 on the first clamping part 24 and the second clamping part 25 prevent the forging from slipping and causing unnecessary safety hazards. During the forging process, if the forging needs to be flipped, the operator can unscrew the knob screw 21 from the bottom of the rotating table 6 and the first screw hole 19, and manually rotate the rotating table 6 by gravity to flip the forging in the clamps. Then, the knob screw 21 is screwed back into the bottom of the rotating table 6 and the second screw hole 20 for fixation.
[0036] After use, the operator can turn the threaded rod 17 counterclockwise again by using the handle 23. The limiting part 15 moves away from the fixed seat 16 on the threaded rod 17. The first rotating arm 11 and the second rotating arm 12 rotate counterclockwise. The first clamping part 24 and the second clamping part 25 move away from each other, and the clamp is in a loose state. At this time, the operator can take the forging out of the clamp.
[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
