Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of metallurgical forging material handling machine, and more specifically, it relates to a clamp structure for a metallurgical forging material handling machine. Background Technology
[0002] Existing material handling machine clamping devices can only stably clamp steel billets when positioned at the center of the billet, where its center of gravity is located. However, in actual production, the billet's center of gravity is not fixed, making it impossible to accurately determine the center of gravity each time before clamping. This results in poor adaptability of the clamping devices, failing to meet the clamping requirements of materials of different shapes and sizes. When clamping materials of different shapes or sizes, fixed-shape clamping devices often fail to locate the billet's center of gravity and maintain proper contact with the material surface, leading to unstable clamping or failure to clamp. Furthermore, existing clamping devices have a relatively simple structure, lacking flexibility and unable to adapt to complex material handling operations.
[0003] Existing technology includes a specification entitled "Clamping Structure on a Billet Clamp, Billet Clamp, and Loading / Unloading Machine," with publication number CN107116491A. This technology provides a clamping structure on a billet clamp, a billet clamp, and a loading / unloading machine. The clamping structure includes two clamping parts connected by clamping arms. Protrusions are provided on the inward-facing sides of the two clamping parts. Each clamping part has multiple protrusions. The connecting portion between adjacent protrusions is a V-shaped recess. Each pair of adjacent protrusions is arranged at a predetermined distance. When the clamping parts clamp the billet, the protrusions contact the outer surface of the billet. This invention can expand the range of billet specifications that the clamping structure can hold.
[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a metallurgical forging material handling clamp structure that is simple in structure, convenient and reliable in achieving billet clamping balance, completing billet grasping operation, and ensuring material handling safety and efficiency, in order to address the shortcomings of the existing technology.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model relates to a clamp structure for a metallurgical forging material handling machine, comprising a first clamp arm and a second clamp arm. A first stop component is provided at the rear of the first clamp arm, and a first downward bend is provided at the front of the first clamp arm. A first concave arc surface is provided on the inner side of the first downward bend. A second stop component is provided at the rear of the second clamp arm, and a second downward bend is provided at the front of the second clamp arm. A second concave arc surface is provided on the inner side of the second downward bend.
[0007] The first clamp arm and the second clamp arm are respectively movably connected to the lifting arm of the material handling machine. The rear part of the first clamp arm and the lifting arm of the material handling machine are connected through a first telescopic component, and the rear part of the second clamp arm and the lifting arm of the material handling machine are connected through a second telescopic component. The lifting arm of the material handling machine is connected to the main body of the material handling machine through a lifting component.
[0008] The first clamp arm and the first downward bend are L-shaped, and the second clamp arm and the second downward bend are L-shaped.
[0009] The steel billet held by the clamp structure of the metallurgical forging material handling machine is a cylindrical structure.
[0010] The point where the first concave arc-shaped surface of the first lower bend clamps the steel billet is the first clamping point. The distance l1 from the first clamping point to the rear end face of the first stop component is less than half of the length L of the billet to be clamped.
[0011] The point where the steel billet is clamped by the second concave arc surface of the second lower bend is the second clamping point. The distance l2 from the second clamping point to the rear end face of the second stop component is less than half of the length L of the billet to be clamped.
[0012] The first clamp arm and the first downward bend are an integral structure, and the second clamp arm and the second downward bend are an integral structure.
[0013] The first and second telescopic components are either pneumatic cylinders or hydraulic cylinders.
[0014] The distance between the inner side of the first stop component and the inner side of the second stop component of the first stop component is less than the diameter of the blank to be clamped.
[0015] The working principle and beneficial effects of this utility model are as follows: The metallurgical forging material handling machine clamp structure of this utility model includes a first clamp arm and a second clamp arm mounted on the material handling machine. The material handling machine can control the lifting and lowering movement and horizontal movement of the first and second clamp arms, which is a mature technology in existing material handling machines. The improvement of this utility model lies in the partial improvement of the clamp structure, while still achieving the lifting and lowering movement and horizontal movement of the first and second clamp arms. The first and second stop components cooperate to stop the rear of the billet. The first concave arc surface of the first downward bend and the second concave arc surface of the second downward bend cooperate to form an annular clamping cavity for reliably clamping the billet. When clamping and retrieving the billet, the first concave arc surface of the first downward bend and the second concave arc surface of the second downward bend clamp the two sides of the billet, and the clamping point is located behind the center of gravity of the billet, that is, the clamping point is located near the rear of the billet. At this time, when clamping and lifting the billet, the front part of the billet, due to its greater weight, falls downward, while the rear part of the billet, due to its relatively lighter weight, rises upward. It is constrained by the first and second stop components and will not continue to rise. In this case, the limiting points formed by the two clamping points and the stop components effectively constrain the billet, preventing it from easily falling from the first and second clamping arms, thus facilitating clamping and retrieving. When using this device, it is not necessary to accurately determine the center of gravity of the billet; it is sufficient that the clamping point is located near the rear of the billet. Therefore, it allows for quick and smooth retrieving, reducing the labor intensity of the operator; the retrieving operation time is reduced from 30 seconds to 8 seconds, improving production efficiency.

[0017] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 -Appendix Figure 3 As shown, this utility model is a clamping structure for a metallurgical forging material handling machine, including a first clamping arm 1 and a second clamping arm 2. A first stop component 3 is provided at the rear of the first clamping arm 1, and a first downward bend 4 is provided at the front of the first clamping arm 1. A first concave arc-shaped surface 5 is provided on the inner side of the first downward bend 4. A second stop component 6 is provided at the rear of the second clamping arm 2, and a second downward bend 7 is provided at the front of the second clamping arm 2. A second concave arc-shaped surface 8 is provided on the inner side of the second downward bend 7. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In the existing material handling machine, the first clamping arm 1 and the second clamping arm 2 are installed on the material handling machine, allowing the machine to control their lifting and horizontal movement. This is a mature technology in existing material handling machines. Therefore, the improvement of this utility model lies in making partial improvements to the clamping structure, while still enabling the lifting and horizontal movement of the first clamping arm 1 and the second clamping arm 2. The first stop component 3 and the second stop component 6 cooperate to stop the rear of the billet. The first concave arc surface 5 of the first lower bend 4 and the second concave arc surface 8 of the second lower bend 7 cooperate to form an annular clamping cavity for reliably clamping the billet. When clamping and lifting the billet, the first concave arc surface 5 of the first lower bend 4 and the second concave arc surface 8 of the second lower bend 7 clamp both sides of the billet, and the clamping point is located behind the center of gravity of the billet, that is, the clamping point is located near the rear of the billet. At this time, when clamping and lifting the billet, the front part of the billet falls downward due to its greater weight, while the rear part of the billet rises upward due to its relatively lighter weight. It is constrained by the first stop component 3 and the second stop component 6 and will not continue to rise. At this time, the limiting point formed by the two clamping points and the stop components is equivalent to constraining the billet. The billet 12 will not easily fall from the first clamping arm 1 and the second clamping arm 2, which facilitates clamping and lifting. Therefore, when using the device of this utility model, it is not necessary to accurately determine the center of gravity of the billet; it is only necessary for the clamping point to be located near the rear of the billet from the center of gravity. This allows for quick and smooth material handling, reducing the labor intensity of operators; the material handling time is reduced from 30 seconds to 8 seconds, improving production efficiency. The clamping structure of the metallurgical forging material handling machine described in this utility model is simple in structure, convenient and reliable in achieving billet clamping and balance, completing the billet grasping operation, and ensuring material handling safety and efficiency.
[0018] The first clamping arm 1 and the second clamping arm 2 are respectively movably connected to the lifting arm 9 of the material handling machine. The rear of the first clamping arm 1 and the lifting arm 9 are connected via a first telescopic component, and the rear of the second clamping arm 2 and the lifting arm 9 are connected via a second telescopic component. The lifting arm 9 is connected to the material handling machine body via a lifting component. In this structure, the lifting component achieves the raising and lowering of the lifting arm relative to the material handling machine body through telescopic movement, while the first clamping arm 1 and the second clamping arm 2 can move horizontally via their respective telescopic components, thereby enabling the first clamping arm 1 and the second clamping arm 2 to approach and open, clamping the billet when approaching and releasing the billet when opening.
[0019] The first clamping arm 1 and the first lower bend 4 are L-shaped, as are the second clamping arm 2 and the second lower bend 7. The steel billet clamped by the clamping structure of the metallurgical forging material handling machine is cylindrical. The clamping of the billet is achieved through the first concave arc surface 7 of the first lower bend 4 and the first concave arc surface 5 of the second lower bend 7.
[0020] The first concave arc-shaped surface 5 of the first lower bend 4 clamps the steel billet at the first clamping point 10. The distance l1 from the first clamping point 10 to the rear end face 11 of the first stop component is less than half the length L of the billet 12 to be clamped. The second concave arc-shaped surface 8 of the second lower bend 7 clamps the steel billet at the second clamping point 13. The distance l2 from the second clamping point 13 to the rear end face 14 of the second stop component is less than half the length L of the billet 12 to be clamped. With the above structure, the first clamping point 10 and the second clamping point 13 do not require time-consuming judgment during clamping; instead, they only need to be positioned close to the rear of the billet 12. The rear position of the billet is the position close to the direction where the billet contacts the stop component.
[0021] The first clamping arm 1 and the first downward bend 4 are integral structures, as are the second clamping arm 2 and the second downward bend 7. In this structure, the first clamping arm 1 and the second clamping arm 2 are each integrally machined, simplifying the manufacturing process and effectively ensuring overall strength.
[0022] The first and second telescopic components are either pneumatic cylinders or hydraulic cylinders.
[0023] The distance between the inner surface 15 of the first stop component 3 and the inner surface 16 of the second stop component 6 is less than the diameter of the blank 12 to be clamped. This structure ensures that when clamping the blank, the rear portion of the blank will not cross the distance between the inner surface 15 of the first stop component and the inner surface 16 of the second stop component 6, thus preventing it from falling off.
[0024] The clamp structure of the metallurgical forging material handling machine described in this utility model, while still enabling the lifting and horizontal movement of the first clamp arm 1 and the second clamp arm 2, has undergone partial improvements, namely, improvements to the clamp structure. The first stop component 3 and the second stop component 6 cooperate to stop the rear of the billet. The first concave arc surface 5 of the first lower bend 4 and the second concave arc surface 8 of the second lower bend 7 cooperate to form an annular clamping cavity for reliably clamping the billet. When clamping and retrieving the billet, the first concave arc-shaped surface 5 of the first lower bend 4 and the second concave arc-shaped surface 8 of the second lower bend 7 clamp both sides of the billet, and the clamping point is located behind the center of gravity of the billet, that is, the clamping point is located near the rear of the billet. At this time, when clamping and lifting the billet, the front part of the billet, due to its greater weight, falls downwards, while the rear part of the billet, due to its relatively lighter weight, rises upwards. It is constrained by the first stop component 3 and the second stop component 6 and will not continue to rise. At this time, the limiting point formed by the two clamping points and the stop components effectively constrains the billet, and the billet 12 will not easily fall from the first clamping arm 1 and the second clamping arm 2, which facilitates clamping and retrieving. Therefore, when using the device of this utility model, it is not necessary to accurately determine the center of gravity of the billet, but only that the clamping point is located near the center of gravity of the billet. Therefore, it is possible to quickly and smoothly retrieve the billet, reducing the labor intensity of the operator; the retrieving operation time is reduced from the original 30 seconds to 8 seconds, improving production efficiency.
