Description

Technical Field

[0001] This utility model relates to the field of clamping devices, specifically to a clamping assembly for forged round forgings. Background Technology

[0002] Forgings are workpieces that have undergone plastic deformation by applying pressure to metal billets using forging equipment (hammers, hydraulic presses, etc.) to obtain specific shapes and properties. Forged rounds refer to forged materials with a circular cross-section (such as round bars, discs, and annular billets). Therefore, forged round forgings refer to workpieces with a circular cross-section. After forged round forgings are formed, they need to be fixed and clamped before further processing. In existing technologies, forged round forgings are fixed and clamped using clamping mechanisms. However, most of these clamping mechanisms are manual. For example, one manual clamping mechanism includes a screw, two jaws, and a nut. The two jaws are pivotally connected to the nut, and the nut and screw are threaded together. When the screw is manually rotated, the nut moves on the screw, causing the two jaws to move closer or further apart. However, besides manual operation, the opening and closing of the two jaws requires a long time, resulting in low work efficiency. Secondly, if the clamping force of the two jaws is too small during manual operation, the forged round forging is very likely to fall off, posing a threat to the personal safety of the surrounding workers and the operator himself. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a clamping assembly for forged round forgings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a forging round forging clamping assembly, comprising:

[0005] First clamping arm, second clamping arm;

[0006] A drive cylinder having a piston rod;

[0007] A first connecting plate, a second connecting plate, a first support plate, and a second support plate are provided. The first connecting plate and the first support plate are fixedly connected together, and the second connecting plate and the second support plate are fixedly connected together. The first support plate and the second support plate are arranged longitudinally. A first clamping arm is pivotally connected to the first support plate and the second support plate via a first pivot axis, and the first clamping arm is located between the first support plate and the second support plate, thereby enabling the first clamping arm to pivot relative to the first support plate and the second support plate. A second clamping arm is pivotally connected to the first support plate and the second support plate via a second pivot axis, and the second clamping arm is located between the first support plate and the second support plate, thereby enabling the second clamping arm to pivot relative to the first support plate and the second support plate.

[0008] When the piston rod extends and retracts under the drive of the drive cylinder, it causes the first clamping arm and the second clamping arm to move closer to each other and further away from each other.

[0010] Preferably, the device further includes a first sliding sleeve and a second sliding sleeve. The first sliding sleeve has a first sliding through hole that extends through the first sliding sleeve and is adapted to the first clamping arm.

The second adapter block is fixedly mounted on the movable rod, and the second connecting rod is fixedly connected to the second adapter block, thereby fixing the second connecting rod and the movable rod together.

[0013] Preferably, the first clamping arm includes a first component segment, a second component segment, and a third component segment. The first component segment is fixedly connected to one end of the second component segment, and the other end of the second component segment is fixedly connected to the third component segment. The included angle between the first component segment and the second component segment is greater than 90 degrees and less than 180 degrees. The included angle between the second component segment and the third component segment is greater than 90 degrees and less than 180 degrees.

Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0020] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0021] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the objects being described and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0022] Please refer to Figure 1-2 This application provides a clamping assembly for forged round forgings (hereinafter referred to as "the clamping assembly"), the clamping assembly comprising:

[0023] First clamping arm 2, second clamping arm 3;

[0024] A drive cylinder 1, wherein the drive cylinder 1 has a piston rod 100;

[0025] A first connecting plate 4, a second connecting plate 5, a first support plate 13, and a second support plate 14 are provided. The first connecting plate 4 and the first support plate 13 are fixedly connected together, and the second connecting plate 5 and the second support plate 14 are fixedly connected together. The first support plate 13 and the second support plate 14 are arranged longitudinally. The first clamping arm 2 is pivotally connected to the first support plate 13 and the second support plate 14 via the first pivot shaft 15, and the first clamping arm 2 is located between the first support plate 13 and the second support plate 14, thereby enabling the first clamping arm 2 to pivot relative to the first support plate 13 and the second support plate 14. The second clamping arm 3 is pivotally connected to the first support plate 13 and the second support plate 14 via the second pivot shaft 16, and the second clamping arm 3 is located between the first support plate 13 and the second support plate 14, thereby enabling the second clamping arm 3 to pivot relative to the first support plate 13 and the second support plate 14.

[0026] When the piston rod 100 extends and retracts under the drive of the drive cylinder 1, it causes the first clamping arm 2 and the second clamping arm 3 to move closer and further apart. Thus, when the first clamping arm 2 and the second clamping arm 3 move closer together, the forged round workpiece is clamped; when the first clamping arm 2 and the second clamping arm 3 move further apart, the forged round workpiece is released. In this application, the first connecting plate 4 and the first support plate 13 can be fixedly connected together by welding or by bolts / screws. Similarly, the second connecting plate 5 and the second support plate 14 can be fixedly connected together by welding or by bolts / screws.

[0027] Please refer to some embodiments of this application. Figure 1-2 The clamping assembly further includes a movable rod 6, a first connecting rod 9, and a second connecting rod 10. One end of the first connecting rod 9 is connected to the first clamping arm 2, and the other end of the first connecting rod 9 is connected to the movable rod 6. One end of the second connecting rod 10 is connected to the second clamping arm 3, and the other end of the second connecting rod 10 is connected to the movable rod 6. The movable rod 6 is connected to the piston rod 100 of the drive cylinder 1, so that when the piston rod 100 extends or retracts, it drives the movable rod 6 to move. The movement of the movable rod 6 drives the first connecting rod 9 and the first connecting rod 10 to move, so that the first clamping arm 2 and the second clamping arm 3 move closer to or further away from each other.

[0028] Please refer to some embodiments of this application. Figure 1-2The clamping assembly further includes a first sliding sleeve 11 and a second sliding sleeve 12. The first sliding sleeve 11 has a first sliding through hole 110, which is through the first sliding sleeve 11 and is adapted to the first clamping arm 2. The first clamping arm 2 extends into the first sliding through hole 110, thereby allowing the first sliding sleeve 11 to slide on the first clamping arm 2. The second sliding sleeve 12 has a second sliding through hole 120, which is through the second sliding sleeve 12 and is adapted to the second clamping arm 3. The second clamping arm 3 extends into the second sliding through hole 120, thereby allowing the second sliding sleeve 12 to slide on the second clamping arm 3.

[0029] Please refer to some embodiments of this application. Figure 1-2 One end of the first connecting rod 9 is fixedly connected to the first sliding sleeve 11, and the other end of the first connecting rod 9 is fixedly connected to the moving rod 6; one end of the second connecting rod 10 is fixedly connected to the second sliding sleeve 12, and the other end of the second connecting rod 10 is fixedly connected to the moving rod 6. Thus, when the driving cylinder 1 drives the piston rod 100 to extend or retract, it causes the moving rod 6 to move. The moving rod 6 causes the first connecting rod 9 and the second connecting rod 10 to move. The first connecting rod 9 causes the first sliding sleeve 11 to slide on the first clamping arm 2. When the first sliding sleeve 11 slides on the first clamping arm 2, it forces the first clamping arm 2 to pivot relative to the first support plate 13 and the second support plate 14. Similarly, the second connecting rod 10 causes the second sliding sleeve 12 to slide on the second clamping arm 3. When the second sliding sleeve 12 slides on the second clamping arm 3, it forces the second clamping arm 3 to pivot relative to the first support plate 13 and the second support plate 14, thereby causing the first clamping arm 2 and the second clamping arm 3 to move closer to or further away from each other.

[0030] Please refer to some embodiments of this application. Figure 1-2 The clamping assembly further includes a first adapter block 7 and a second adapter block 8. The first adapter block 7 is fixedly mounted on the moving rod 6, and the first connecting rod 9 is fixedly connected to the first adapter block 7, thereby fixing the first connecting rod 9 and the moving rod 6 together. The second adapter block 8 is fixedly mounted on the moving rod 6, and the second connecting rod 10 is fixedly connected to the second adapter block 8, thereby fixing the second connecting rod 10 and the moving rod 6 together.

[0031] Please refer to some embodiments of this application. Figure 1-2The first clamping arm 2 includes a first component segment 21, a second component segment 22, and a third component segment 23. The first component segment 21 is fixedly connected to one end of the second component segment 22, and the other end of the second component segment 22 is fixedly connected to the third component segment 23. The included angle between the first component segment 21 and the second component segment 22 is greater than 90 degrees and less than 180 degrees. The included angle between the second component segment 22 and the third component segment 23 is greater than 90 degrees and less than 180 degrees.

[0032] Please refer to some embodiments of this application. Figure 1-2 The second clamping arm 3 includes a fourth segment 31, a fifth segment 32, and a sixth segment 33. The fourth segment 31 is fixedly connected to one end of the fifth segment 32, and the other end of the fifth segment 32 is fixedly connected to the sixth segment 33. The angle between the fourth segment 31 and the fifth segment 32 is greater than 90 degrees and less than 180 degrees, and the angle between the fifth segment 32 and the sixth segment 33 is greater than 90 degrees and less than 180 degrees. Thus, a clamping space 20 is formed between the first clamping arm 2 and the second clamping arm 3. The size of the clamping space 20 is variable; when the first clamping arm 2 and the second clamping arm 3 are close to each other, the clamping space 20 becomes smaller; conversely, when the first clamping arm 2 and the second clamping arm 3 are far apart, the clamping space 20 becomes larger.

[0033] Please refer to some embodiments of this application. Figure 1-2 The clamping assembly also includes a mounting bracket 17 on which the drive cylinder 1 is mounted.

[0034] The forging round forging clamping assembly provided in this application has the advantages of simple structure and easy assembly; secondly, given that a drive cylinder is provided, the drive cylinder provides a power source, which drives the first clamping arm and the second clamping arm to move closer and further away from each other, thereby clamping the forging round forging relatively quickly and with a large clamping force.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
