Description

Technical Field

[0001] This utility model relates to the field of chains, specifically to a winding sleeve, chain and flat wire grooving machine with an oil groove. Background Technology

[0002] A chain is a mechanical component widely used in mechanical transmission, transportation and other fields. It typically includes inner chain plates, outer chain plates, sleeves and pins. Two inner chain plates are arranged opposite each other and connected by two sleeves to form an inner chain link. The inner chain links are distributed in sequence and connected in series by the outer chain plate and pins to form a chain. The pins pass through the sleeves.

[0003] During chain operation, the pin and sleeve oscillate back and forth, inevitably causing wear between them. To reduce wear, lubricating grease is usually filled between the pin and sleeve. The lubrication effect directly affects the chain's service life. However, in existing chains, the space between the pin and sleeve is limited, often resulting in insufficient lubrication and affecting the chain's overall lifespan. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a winding sleeve, chain and flat wire grooving machine with oil groove. By setting oil groove on the inner wall of the cylinder, the oil storage capacity can be effectively increased, the distribution of lubricating grease can be optimized, and thus the overall working life of the chain can be improved.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a rolled sleeve with an oil groove, comprising a cylinder body, wherein the inner wall of the cylinder body is provided with a first oil groove and a second oil groove; the first oil groove extends spirally along the axial direction of the cylinder body, and the second oil groove extends circumferentially around the axis of the cylinder body; the number of the first oil grooves is not less than two, and each of the first oil grooves is arranged relatively parallel to each other, and the second oil groove is connected to each of the first oil grooves.

[0006] The inclusion of a first and second oil groove increases the oil storage space between the pin and the sleeve, thereby increasing the oil capacity between them. The first oil groove improves the distribution of lubricating grease axially, while the second oil groove improves it circumferentially. By incorporating these grooves on the inner wall of the cylinder, the oil capacity is effectively increased, the distribution of lubricating grease is optimized, and the overall service life of the chain is improved.

[0007] Preferably, the cross-sections of the first and second oil grooves are arc-shaped; the depth of the first oil groove is denoted as t1, the depth of the second oil groove as t2, and the wall thickness of the cylinder as T, then: t1 = (0.2~0.3)T, t2 = (0.2~0.3)T; the helix angle of the first oil groove is denoted as α, then: α = 5°~10°; the length of the sleeve is denoted as H, and the extension length of the first oil groove in the axial direction is denoted as L, then L = (0.4~0.7)H. While increasing the oil storage space, the weakening of the sleeve structure strength is minimized, while simultaneously considering lubrication performance and mechanical properties.

[0008] Preferably, there are at least two second oil grooves, which are arranged relatively parallel to each other. This allows for the simultaneous distribution of lubricating grease in both the radial and axial directions.

[0009] A rolled sleeve with an oil groove includes a cylinder body, the inner wall of which is provided with a first oil groove, the first oil groove extending spirally along the axial direction of the cylinder body; the first oil groove includes a first segment and a second segment along the axial direction of the cylinder body, the first segment and the second segment having opposite spiral directions and being interconnected.

[0010] Preferably, the inner wall of the cylinder is also provided with a second oil groove, which extends circumferentially around the axis of the cylinder, and the second oil groove is connected to each of the first oil grooves.

The pre-rolling assembly, forming assembly, and finishing rolling assembly are respectively connected to the frame and are distributed in sequence.

[0013] The forming component includes a support wheel and a forming wheel. A forming punch is provided on the circumferential surface of the forming wheel. The forming punch includes a first punch and a second punch.

The two pre-rolling rollers in the pre-rolling assembly pre-shape the flat wire, ensuring its flatness during grooving and improving the grooving quality. The forming rollers in the forming assembly use forming punches to press oil reservoirs onto one side of the flat wire. The two finishing rollers in the finishing rolling assembly correct any deformation that occurs during grooving, preparing for subsequent sleeve winding operations. Simultaneously, the flat wire is continuously fed along with the pre-rolling, forming, and finishing rolling assemblies, ensuring continuous grooving processing.

[0016] The flat wire grooving machine of this application can automatically and efficiently perform grooving operations using flat wire as raw material, and has the advantage of high forming quality.

[0017] Preferably, the assembly also includes a material guiding component, which includes two guide wheels that are rotatably connected to the frame, and the axis of the guide wheels is perpendicular to the axis of the forming wheel.

[0018] The material guiding assembly can limit and guide the flat wire in the width direction, ensuring that the flat wire is aligned with the forming punch in width, and the forming position of the right groove is accurate and reliable.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example

[0034] like Figure 1 and Figure 2 As shown, a rolled sleeve with oil grooves includes a cylindrical body 1.

The first oil groove 21 extends spirally along the axial direction of the cylindrical body 1, and there are at least two first oil grooves 21 arranged relatively parallel to each other. The second oil groove 22 extends circumferentially around the axis of the cylindrical body 1, and is connected to each of the first oil grooves 21. The cylindrical body 1 is formed by rolling flat wire, and the end of the corresponding second oil groove 22 does not extend to the end of the flat wire.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, the cross-sections of the first oil groove 21 and the second oil groove 22 are arc-shaped; the depth of the first oil groove 21 is denoted as t1, the depth of the second oil groove 22 is denoted as t2, and the wall thickness of the cylinder 1 is denoted as T. Therefore, t1 = (0.2~0.3)T, t2 = (0.2~0.3)T. While increasing the oil storage space, the weakening of the sleeve structure strength is minimized, while simultaneously considering lubrication performance and mechanical properties.

[0036] Specifically, such as Figure 2 As shown, the helix angle of the first oil groove 21 is denoted as α, then α = 5°~10°; the length of the sleeve is denoted as H, and the extension length of the first oil groove 21 in the axial direction is denoted as L, then L = (0.4~0.7)H.

[0037] The oil grooves increase the oil storage space between the pin and the sleeve, thereby increasing the oil storage capacity between them. The first oil groove 21 improves the distribution of lubricating grease in the axial direction, while the second oil groove 22 improves the distribution in the circumferential direction. By providing oil grooves on the inner wall of the cylinder 1, the oil storage capacity can be effectively increased, the distribution of lubricating grease can be optimized, and the overall service life of the chain can be improved.

Specifically, along the circumferential direction, the forming punch includes several groups. The second punch in each group is integrally formed with the first punch. The number of second punches is not less than two, and the second punches in each group are discontinuous in the circumferential direction.

[0048] like Figures 8-10 As shown, it also includes a material guiding assembly 5, which includes two guide wheels. The guide wheels are rotatably connected to the frame 3, and the axis of the guide wheels is perpendicular to the axis of the forming wheel 81. The material guiding assembly 5 can limit and guide the flat wire in the width direction, ensuring that the flat wire is aligned with the forming punch in width, and that the forming position of the right groove is accurate and reliable.

[0049] During the grooving process, flat wire material 6 is selected as the raw material and processed sequentially through the pre-rolling assembly 9, the forming assembly 8, and the finishing rolling assembly 7. The two pre-rolling rollers 91 in the pre-rolling assembly 9 pre-shape the flat wire material, ensuring its flatness during the grooving process and improving the grooving quality. The forming rollers 81 in the forming assembly 8 press an oil reservoir on one side of the flat wire material using a forming punch. The two finishing rollers 71 in the finishing rolling assembly 7 are used to correct the deformation of the flat wire material during the grooving process, preparing it for subsequent sleeve winding operations.
