Description

Technical Field

[0001] This utility model relates to the field of track structure technology, and more specifically, to a track structure for a lifting trolley of an uncoiler in a CNC stamping production line. Background Technology

[0002] A track structure is a rigid structure used to support and guide moving parts (such as vehicles, machine sliders, lifting equipment, etc.) along a predetermined path. It is typically made of metal and can be straight, curved, or a combination of straight and curved segments to accommodate different motion trajectory requirements. The design of a track structure needs to consider factors such as load capacity, wear resistance, stability, precision, and ease of maintenance to ensure smooth and accurate operation of the moving parts, while also having a long service life and low maintenance costs. In industrial applications, track structures are commonly found in railway systems, cranes, machine tools, and conveying equipment.

[0003] A search revealed an existing patent (publication number: CN217376084U) that discloses a KNS block sliding track structure with good wear resistance, including a feeding mechanism and a discharging mechanism; a block track is provided between the feeding mechanism and the discharging mechanism; the block track is provided with a U-shaped groove for the passage of KNS blocks; and the U-shaped groove is provided with an embedding groove for fixing hard alloy inserts. The beneficial effect of this technology is that by improving the internal structure of the track, the local wear resistance of the track is improved while controlling the manufacturing cost, thereby further extending the service life of the track.

[0004] However, the aforementioned device has been subjected to frequent operation and heavy load pressure from the uncoiler's lifting trolley over a long period of time, resulting in severe wear and tear. Furthermore, over time, the track has gradually deformed, which not only affects the accuracy and stability of the lifting trolley's operation but also brings serious safety hazards such as trolley derailment. It also leads to an increase in equipment failure rate, a significant increase in maintenance costs, and great disruption to normal production. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a track structure for the lifting trolley of the uncoiler in a CNC stamping production line, so as to solve the problem of track wear and deformation caused by high load, which endangers safety and increases costs.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lifting trolley track structure for an uncoiler in a CNC stamping production line, comprising: a moving track; a sliding block assembly mounted on the moving track, the sliding block assembly being used to drive the trolley to move; an auxiliary sliding assembly mounted at the bottom of the sliding block assembly, the auxiliary sliding assembly being used to assist in supporting and assisting in sliding; an upper ball bearing sliding assembly mounted on the moving track, the upper ball bearing sliding assembly being used to help reduce friction generated during sliding; and a lower ball bearing sliding assembly mounted on the moving track, the lower ball bearing sliding assembly being used to assist the sliding block assembly in sliding.

[0007] Preferably, the sliding block assembly includes: a main sliding block movably mounted on the moving track, an auxiliary sliding block body fixedly mounted on one side of the main sliding block, and a ball bearing sliding groove formed on the top of the auxiliary sliding block body.

[0008] Preferably, the auxiliary sliding assembly includes: a reinforcing rib fixedly installed at the bottom of the auxiliary sliding block body, a polytetrafluoroethylene block fixedly installed at the bottom of the reinforcing rib, multiple sets of the reinforcing ribs being provided, the multiple sets of the reinforcing ribs being equidistantly arranged on the polytetrafluoroethylene block, and connecting ribs fixedly installed on the multiple sets of the polytetrafluoroethylene block.

[0009] Preferably, the upper ball bearing sliding assembly includes: a mounting groove 1 formed inside the moving track, a ball bearing 1 movably mounted inside the mounting groove 1, an oil pipe formed inside the moving track, and a branch pipe formed on one side of the oil pipe.

[0010] Preferably, multiple sets of the mounting groove, ball bearing, and branch pipe are provided, and the multiple sets of the mounting groove, ball bearing, and branch pipe are equidistantly arranged on the moving track.

[0011] Preferably, the lower ball bearing sliding assembly includes: a second mounting groove formed on the moving track, wherein a second ball bearing is movably mounted inside the second mounting groove.

[0012] Preferably, multiple sets of the second mounting groove and the second ball bearing are provided, and the multiple sets of the second mounting groove and the second ball bearing are equidistantly arranged on the moving track.

[0013] Preferably, there are two sets of the moving track, auxiliary sliding component, upper ball sliding component, and lower ball sliding component, and the two sets of the moving track, auxiliary sliding component, upper ball sliding component, and lower ball sliding component are symmetrically arranged on the sliding block component.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a lifting trolley along with a main sliding block, which presses against the upper ends of two moving tracks. One ball bearing rolls within the upper ball bearing sliding assembly, while another ball bearing is simultaneously lifted within the lower ball bearing sliding assembly. The friction between the sliding block assembly and the tracks changes from traditional sliding friction to multi-point rolling friction, significantly reducing the coefficient of friction. Simultaneously, the PTFE block at the bottom of the auxiliary sliding block makes lateral contact with the tracks, providing self-lubricating guidance and sharing lateral loads. Multiple sets of reinforcing ribs and connecting ribs form a box-shaped structure that further suppresses deformation. Oil pipes continuously inject grease into the ball bearing area through branch pipes, maintaining a low-wear state. Throughout operation, the trolley moves smoothly and positions accurately, significantly reducing track wear and deformation caused by repeated high-load impacts, fundamentally suppressing the risk of derailment. Furthermore, the modular and quick-disassembly design of each component reduces maintenance time from several hours to just a few minutes, simultaneously lowering the failure rate and downtime costs, allowing the production line to operate continuously and efficiently.

[0028] Example 2

[0029] Based on Embodiment 1, a preferred embodiment of the CNC stamping production line uncoiler lifting trolley track structure provided by this utility model is, for example... Figures 1 to 5 As shown: The upper ball sliding assembly 4 includes: a mounting groove 401 opened inside the moving track 1, a ball 402 movably installed inside the mounting groove 401, an oil pipe 403 opened inside the moving track 1, and a branch pipe 404 opened on one side of the oil pipe 403.
