Description

Technical Field

[0001] This utility model relates to the field of lower roller support technology for long tube rolling machines, specifically a lower roller support mechanism for long tube rolling machines. Background Technology

[0002] A plate rolling machine is a device that uses work rolls to bend sheet metal into various shapes, such as cylindrical and conical parts, making it a crucial processing equipment. The working principle of a plate rolling machine involves using hydraulic pressure, mechanical force, or other external forces to move the work rolls, thereby bending or rolling the sheet metal into shape. Long tube plate rolling machines, due to their considerable length, typically use a lower roll support mechanism to ensure the lower roll's stability. However, existing lower roll support mechanisms generally employ fixed supports, and the inability to adjust the roll height reduces flexibility. Therefore, an improved technology is urgently needed to address this problem in the current technology. Utility Model Content

A hydraulic cylinder is mounted on the upper surface of the base, with its piston rod pointing upwards and supported at the bottom of the lifting frame. Side guide blocks are mounted on both sides of the hydraulic cylinder, each with a guide groove extending vertically through it. The lifting frame includes side plates, longitudinal connecting plates, support plates, connecting sleeves, and rollers. There are two side plates, with several longitudinal connecting plates positioned between the two side plates and at their top. The longitudinal connecting plates connect two parallel support plates. Two connecting sleeves are positioned between the two support plates and above the longitudinal connecting plates. Rollers are coaxially mounted inside each connecting sleeve, with support rollers mounted at both ends of each roller. Each side plate corresponds to one side guide block. An extended guide section is provided at the bottom of each side plate, and the extended guide section guides and engages with the guide groove of the corresponding side guide block.

[0020] Please see Figures 1-4This utility model provides a technical solution: a lower roller support mechanism for a long tube rolling machine, including a base 1, a hydraulic cylinder 2, a side guide block 3, a lifting frame 4, and a support roller 5. The hydraulic cylinder 2 is mounted on the upper surface of the base 1, and a limiting ring 6 is provided on the upper surface of the base 1. The outer surface of the bottom of the hydraulic cylinder 2 is tightly connected to the inner wall of the limiting ring 6. The bottom of the hydraulic cylinder 2 is fastened to the base 1 by bolts. The limiting ring 6 further improves the stability of the connection between the hydraulic cylinder 2 and the base 1. The piston rod of the hydraulic cylinder 2 faces upward and is supported at the bottom of the lifting frame 4. Side guide blocks 3 are provided on both sides of the pressure cylinder 2. The side guide blocks 3 have guide grooves that run through them vertically. The lifting frame 4 includes side plates 401, longitudinal connecting plates 402, support plates 403, connecting sleeves 404, and rollers 405. There are two side plates 401. Several longitudinal connecting plates 402 are provided between the two side plates 401 and at the top. Reinforcing plates 407 are provided at the bottom of the longitudinal connecting plates 402 and at the connection points with the side plates 401 to ensure the connection strength of the side plates 401. The longitudinal connecting plates 402 are connected to two parallel support plates. 403. Two connecting sleeves 404 are arranged between the two support plates 403 and above the longitudinal connecting plate 402. Rollers 405 are coaxially arranged inside the connecting sleeves 404, and rollers 5 are provided at both ends of the rollers 405. Side plates 401 correspond one-to-one with side guide blocks 3. An extended guide section 406 is provided at the bottom of the side plate 401. The extended guide section 406 guides and engages with the guide groove of the corresponding side guide block 3. The thickness of the extended guide section 406 is less than the thickness of the side plate 401 to ensure that lifting is possible even if the hydraulic cylinder 2 leaks or is damaged. The frame 4 will not descend directly to the lowest position. A transverse connecting plate 408 is provided between the longitudinal connecting plates 402. The transverse connecting plate 408 ensures the structural stability of the entire lifting frame 4. A support block 409 is provided on the lower surface of the transverse connecting plate 408 at the bottom. The support block 409 is supported on the piston rod of the hydraulic cylinder 2. The support block 409 ensures that the piston rod of the hydraulic cylinder 2 does not directly press against the transverse connecting plate 408 at the bottom, thereby preventing deformation of the transverse connecting plate 408 at the bottom and ensuring the service life of the lifting frame 4.

[0021] Assembly method and operating principle: First, weld the lifting frame 4. Weld several longitudinal connecting plates 402 and transverse connecting plates 408 between the two side plates 401. Weld the two sides of the transverse connecting plates 408 to the longitudinal connecting plates 402. Then, install the support block 409 on the lower surface of the bottom transverse connecting plate 408 and the bottom of the longitudinal connecting plate 402. Before welding the support plate 403, weld two connecting sleeves 404 between the two support plates 403. Then, pass the roller 405 through the connecting sleeve 404 and install the end plate at both ends of the connecting sleeve 404, while limiting the roller 405. Then, install the support roller at both ends of the roller 405. Install the side guide block 3 on both sides of the hydraulic cylinder 2 by welding or bolting. Pass the extended guide section 406 at the bottom of the side plate 401 of the lifting frame 4 through the guide groove of the side guide block 3. At this time, the support block 409 at the bottom of the lifting frame 4 is supported on the piston rod of the hydraulic cylinder 2, completing the assembly. In use, the base 1 is bolted into the long tube rolling machine and positioned below the lower roller. The piston rod of the hydraulic cylinder 2 rises, thereby pushing the lifting frame 4 upward, which in turn supports the lower roller of the long tube rolling machine via the support roller, ensuring the support of the lower roller of the long tube rolling machine. Figure 5 As shown. The hydraulic cylinder 2 works in conjunction with the hydraulic pump station. This utility model has a reasonable structure. The piston rod of the hydraulic cylinder 2 is supported at the bottom of the lifting frame 4. The hydraulic cylinder 2 can drive the lifting frame 4 to rise and fall, thereby controlling the height of the roller 5. Compared with the traditional fixed support structure, the flexibility is greatly improved. Simultaneously, side guide blocks 3 are provided on both sides of the hydraulic cylinder 2. The bottom of the side plates 401 on both sides of the lifting frame 4 are guided and cooperated with the guide grooves of the side guide blocks 3 through extended guide sections 406, thereby ensuring the stability of the lifting frame 4 during lifting. Furthermore, the bottom of the side plates 401 is provided with extended guide sections 406 that are thinner than the side plates 401, cooperating with the side guide blocks to prevent the lifting frame 4 from falling directly to the bottom in the event of leakage from the hydraulic cylinder after a long period of time.
