Description

Technical Field

[0001] The utility model relates to the technical field of forging, in particular to a forging sleeve rod that can increase friction force. Background Art

[0002] The statements in this part only provide background technical information related to the utility model, and do not necessarily constitute prior art.

[0003] In free forging, when forging large-mass components such as components weighing more than 10t, the traveling crane drives the tong handle (lifting tong for flipping) through the sleeve rod to clamp the forging and perform forging through the forging machinery. The inventor found that the existing forging sleeve rod uses an octagonal structure for anti-slip: when forging, the traveling crane chain is used to hold the sleeve rod, and the sleeve rod is driven to rotate by the rotation of the chain. However, when the traveling crane chain rotates, there is still a sliding phenomenon between the sleeve rod and the chain, resulting in a low rotation efficiency of the forging. Summary of the Utility Model

[0029] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present utility model. Unless otherwise specified, all technical and scientific terms used in the present utility model have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0030] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present utility model. As used herein, unless the present utility model clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof;

[0031] As introduced in the background art, in the prior art, there is a problem that slippage easily occurs between the sleeve rod and the chain used for forging large components. To solve the above technical problems, the present utility model proposes a forging sleeve rod that can increase friction.

[0032] Embodiment 1

[0033] In a typical embodiment of the present utility model, referring to Figure 1 As shown, a forging sleeve rod that can increase friction includes a sleeve body 3. The sleeve body 3 is a hollow rod or a solid rod. The sleeve body 3 has a multi-prismatic structure. Anti-slip members 2 are provided on some or all of the side surfaces of the sleeve body 3. The anti-slip members at multiple positions on the side surface of the sleeve body 3 are all arranged along the same axial direction of the sleeve body. The anti-slip members are arranged along the length direction of the sleeve body. Along the axial direction of the sleeve body 3, the range where the anti-slip members 2 are provided is greater than or equal to half of the length of the sleeve body, so that the anti-slip members 2 cover all areas where the chain contacts the sleeve rod.

[0034] It should be noted that along the axial direction of the sleeve body 3, the anti-slip member 2 is in a long strip shape. In this way, the anti-slip member is an anti-slip strip. The long-strip anti-slip member 2 effectively increases the friction between the sleeve rod and the chain, and the long-strip protective member is convenient to be fixed on the outer surface of the sleeve body.

[0035] Considering that the sleeve body 3 has a multi-prismatic structure, along the circumferential direction of the sleeve body 2, the adjacent two anti-slip members are arranged at an interval of a set angle. That is, in some examples, the anti-slip members 2 are provided on each side surface of the sleeve body, and in other examples, the anti-slip members can be arranged at intervals of the side surfaces of the sleeve body.

[0036] It is easily understood that the cross-section of the sleeve body 3 is an n-sided polygon, where n is greater than or equal to 6. Specifically, referring to Figure 2 As shown, the sleeve body (except for the first reduced-diameter section and the second reduced-diameter section) can be an octagonal prism. Of course, in other examples, the sleeve body can also be a prism structural member of other shapes. The anti-slip members 2 are provided in the middle of each side surface of the sleeve body. In this way, the anti-slip members are arranged between adjacent edges of the sleeve body and effectively cooperate with the edges to reduce the sliding phenomenon during chain transmission.

[0037] In this embodiment, along each side surface of the sleeve body 3, multiple anti-slip members are arranged in the same axial direction of the sleeve body. Along the longitudinal section of the sleeve body, one anti-slip member is arranged on each side surface of the sleeve body, and the distance between adjacent anti-slip members on each side surface is set at intervals, and the distance between adjacent anti-slip members on each side surface is set to be 1 / 10 - 1 / 6 of the length of the anti-slip member.

[0038] Considering the connection between the anti-slip member 2 and the sleeve body 3, at least three anti-slip members are arranged along each side surface of the sleeve body. In this embodiment, three anti-slip members can be arranged, and the length of each anti-slip member is 1 / 9 - 1 / 5 of the sleeve body, which is convenient for the installation of the anti-slip member; moreover, the lengths of the anti-slip members arranged on adjacent side surfaces of the sleeve body are the same.

[0039] Specifically, since the sleeve body is an integrally manufactured part and it is not easy to arrange the anti-slip member on the outer side surface of the sleeve body, the anti-slip member is welded to the sleeve body.

[0040] For the convenience of processing and manufacturing, the transverse section of the anti-slip member is rectangular, and the longitudinal section of the anti-slip member is also rectangular. In this way, it can be understood that on the premise of ensuring an increase in the friction between the anti-slip member and the sleeve body, damage to the anti-slip member is avoided, and the height of the anti-slip member is less than or equal to the thickness of the sleeve body.

[0041] In this embodiment, with reference to Figure 3 As shown, the length L of the anti-slip member ≥ 1000 mm, where the width of the anti-slip member is 40 - 60 mm, and the thickness of the anti-slip member is 40 - 60 mm, which is convenient for the processing and manufacturing of the anti-slip member and also convenient for welding the anti-slip member to the outer surface of the sleeve body.

[0042] In addition, a first reduced-diameter section 1 is arranged at one end of the sleeve body 3, and a second reduced-diameter section 4 is arranged at the other end. The length of the second reduced-diameter section 4 is greater than the length of the first reduced-diameter section 1. The first reduced-diameter section is used for connection with the counterweight, and the second reduced-diameter section is used for connection with the existing tongs (for clamping forgings); the longitudinal sections of the first reduced-diameter section 1 and the second reduced-diameter section 4 are specifically circular.

[0043] The sleeve rod provided in this embodiment, the sleeve body 3 is a multi-prismatic structure, that is, multiple edges are arranged on the outer side surface of the sleeve body 3. Coupled with the protective member 2 arranged on the circumferential surface of the sleeve body, when the sleeve body contacts the chain, the friction between the two is effectively enhanced, the sliding between the chain and the sleeve rod is effectively reduced, the chain transmission efficiency is improved, the forging time is reduced, the forging efficiency is improved, and the forging cost is reduced; by setting the sleeve rod as an octagonal prism, along the outer side surface of the sleeve rod in a circle, the anti-slip member and the eight edges of the sleeve rod form 16 anti-slip points, so as to play a role in reducing sliding when the chain drives the sleeve rod to rotate. Compared with the traditional sleeve rod structure, the chain transmission efficiency can be increased by 20 - 30%.

[0044] Embodiment Two

[0045] The difference between this embodiment and the first embodiment lies in that:

[0046] The lengths of the anti-slip members provided on two adjacent side surfaces of the sleeve body are different, that is, the anti-slip members on some side surfaces cover the space between two adjacent anti-slip members on the adjacent side surface; thus, in some examples, along the outer side surface of the sleeve body, from the first side surface to the last side surface, the lengths of the anti-slip members increase in sequence; or, along the outer side surface of the sleeve body, the anti-slip members on two adjacent side surfaces are arranged in a staggered manner, so that within the range where the sleeve rod contacts the chain during the rotation of the sleeve rod driven by the chain, anti-slip members are provided, effectively improving the transmission efficiency of the chain.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
