Description

Technical Field

[0001] This utility model relates to the technical field of welded pipe roller bending forming device, specifically a welded pipe roller bending forming flat roller anti-scratch adjustment mechanism. Background Technology

[0002] The anti-scratch adjustment mechanism for the flat roller in welded pipe bending forming is a specialized component adapted to the welded pipe bending forming process and applied in welded pipe production scenarios. Its core functionality is adapted to the requirements of steel strip bending forming in welded pipe production, fitting the flat roller installation structure, welded pipe forming process parameters, and steel strip material characteristics. It enables precise adjustment of the flat roller spacing, angle, and contact pressure. Simultaneously, it adapts to the surface protection requirements during the contact process between the flat roller and the steel strip, connecting the flat roller adjustment and steel strip anti-scratch functions. It provides adaptive support for continuous and diversified welded pipe production and is a key mechanism for ensuring the forming accuracy of welded pipe and the surface quality of the steel strip.

[0003] The feeding section of some existing welded pipe bending forming flat rollers lacks effective protection. During feeding, the welded pipe position often needs to be manually adjusted to align with the flat roller. This not only increases the safety hazard of human hands touching the machine's operating area but also may cause the welded pipe to shift due to human error, resulting in friction and scratches against the edge of the flat roller. Therefore, we propose a scratch-resistant adjustment mechanism for welded pipe bending forming flat rollers. Utility Model Content

[0004] The purpose of this utility model is to provide a scratch-resistant adjustment mechanism for the flat roller of welded pipe bending forming, so as to solve the problem that the feeding part of some existing flat rollers of welded pipe bending forming lacks effective protection. When feeding, it is often necessary to manually adjust the position of the welded pipe to align with the flat roller. This not only increases the safety hazard of human hands touching the machine's operating area, but may also cause the welded pipe to deviate due to human operation error, which in turn causes friction and scratches on the edge of the flat roller.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welded pipe roll forming flat roll anti-scratch adjustment mechanism, comprising: a bending machine, a fixed plate fixedly connected to the outer surface of the bending machine, a support seat fixedly connected to the outer surface of the fixed plate, a support plate fixedly connected to the upper surface of the support seat, an adjusting seat movably connected to the upper surface of the support plate, a limit groove opened inside the adjusting seat, a movable groove opened at the top of the support plate, a fixed block fixedly connected inside the movable groove, damping springs fixedly connected to both sides of the fixed block, a limit ring fixedly connected to the outer surface of the damping spring, and a limit block fixedly connected to the outer surface of the limit ring.

[0006] The outer surface of the fixed plate is movably connected with a connecting bolt, and the fixed plate is fixedly connected to the outer surface of the bending machine through the connecting bolt.

[0007] The outer surface of the adjusting seat is fixedly connected to a pressing plate, and the top of the adjusting seat is fixedly connected to a clamping assembly.

[0008] The limiting block is movably connected to the inside of the limiting groove, and the limiting block and the limiting groove are arranged in two symmetrical sets at the connection between the adjusting seat and the support plate.

[0009] The clamping assembly includes an I-beam guide plate, a movable block is movably connected to the upper surface of the I-beam guide plate, and a guide plate is fixedly connected to the upper surface of the movable block.

[0010] The outer surface of the movable block is fixedly connected to a guide seat, and the inside of the guide seat is movably connected to a screw.

[0011] The screw is fixedly connected to a rotating handle at the end away from the guide seat, and the screw is movably connected to the side surface of the I-beam guide plate through the rotating handle.

[0012] The movable block and the guide plate are connected in two sets to the upper surface of the I-beam guide plate, and the guide plate is crescent-shaped.

[0013] This utility model has at least the following beneficial effects: 1. In use, this utility model achieves smooth buffering and safety protection during the feeding process through the setting of an adjusting seat, damping spring, and limiting block. The adjusting seat, together with the pressing plate, allows for remote adjustment of the welded pipe height, eliminating the need for manual contact with the machine's flat roller area and preventing safety hazards. The limiting groove and limiting block precisely constrain the movement trajectory, preventing deviation and jamming; the damping spring buffers the impact force of lifting and lowering through elastic deformation, preventing rigid collision between the welded pipe and the flat roller. This effectively reduces scratches on the welded pipe surface, ensures the safety and stability of the feeding operation, provides a precise alignment basis for subsequent forming processes, and improves the overall safety factor and ease of operation.

[0014] 2. In use, this utility model achieves precise positioning and clamping of the welded pipe through its clamping components, screw, and crescent-shaped guide plate. Rotating the drive screw moves the movable block along the I-beam guide plate, flexibly adjusting the guide plate spacing to accommodate welded pipes of different diameters. The crescent-shaped structure conforms to the outer wall of the welded pipe, ensuring centered positioning while avoiding clamping and squeezing damage. No manual adjustment of the welded pipe position is required, achieving non-contact pre-positioning and reducing human error and the risk of scratches. It improves the positioning accuracy and feeding efficiency of the welded pipe, ensures the consistency of roll forming quality, enhances the adaptability of the mechanism to diverse workpieces, and reduces operational difficulty and labor intensity.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a welded pipe roller bending forming flat roller anti-scratch adjustment mechanism, including: a bending machine 1, a fixed plate 2 fixedly connected to the outer surface of the bending machine 1, a support seat 4 fixedly connected to the outer surface of the fixed plate 2, a support plate 5 fixedly connected to the upper surface of the support seat 4, an adjusting seat 6 movably connected to the upper surface of the support plate 5, a limiting groove 9 opened inside the adjusting seat 6, a movable groove 10 opened at the top of the inside of the support plate 5, a fixed block 11 fixedly connected inside the movable groove 10, damping springs 12 fixedly connected to both sides of the fixed block 11, a limiting ring 13 fixedly connected to the outer surface of the damping spring 12, and a limiting block 14 fixedly connected to the outer surface of the limiting ring 13.

[0019] During operation, the adjustable seat 6, damping spring 12, and limiting block 14 ensure smooth buffering and safety during the feeding process. The adjustable seat 6, in conjunction with the pressing plate 7, allows for remote adjustment of the welded pipe height, eliminating the need for manual contact with the machine's flat roller area and preventing potential safety hazards. The limiting groove 9 and limiting block 14 precisely constrain the movement trajectory, preventing deviation and jamming; the damping spring 12 buffers the impact force of lifting and lowering through elastic deformation, preventing rigid collisions between the welded pipe and the flat roller. This effectively reduces scratches on the welded pipe surface, ensuring the safety and stability of the feeding operation, providing a precise alignment basis for subsequent forming processes, and improving the overall safety and ease of operation.

[0020] A connecting bolt 3 is movably connected to the outer surface of the fixed plate 2, and the fixed plate 2 is fixedly connected to the outer surface of the bending machine 1 through the connecting bolt 3. A pressing plate 7 is fixedly connected to the outer surface of the adjusting seat 6, and a clamping assembly 8 is fixedly connected to the top of the adjusting seat 6. A limiting block 14 is movably connected to the inner side of the limiting groove 9, and the limiting block 14 and the limiting groove 9 are arranged in two symmetrical sets at the inner connection between the adjusting seat 6 and the support plate 5.

[0021] During use, the fixing plate 2 is firmly fixed to the outer surface of the bending machine 1 by the connecting bolt 3. The support base 4 and the support plate 5 form a stable double-layer support structure, providing a solid and stable lifting platform for the adjusting seat 6. Before loading, there is no need for direct contact with the machine's flat roller area. First, by pressing the pressing plate 7 on the outer surface of the adjusting seat 6, the adjusting seat 6 is driven to make precise lifting and lowering adjustments along the support plate 5. The two sets of symmetrical limiting grooves 9 on the inner side of the adjusting seat 6 and the limiting blocks 14 in the movable groove 10 of the support plate 5 form a bidirectional guiding cooperation, precisely limiting the movement trajectory of the adjusting seat 6 and avoiding deviation and jamming during the lifting process. The damping springs 12 on both sides of the fixed block 11 form a uniform elastic support for the limiting block 14 through the limiting ring 13. When the adjusting seat 6 drives the subsequently clamped welding pipe to approach the flat roller, the damping springs 12 can adaptively generate elastic deformation according to the lifting force, effectively buffering the lifting impact force and avoiding rigid collision between the welding pipe and the flat roller, which would cause scratches. At the same time, it provides a flexible buffer guarantee for the precise alignment of the welding pipe and the flat roller, eliminating the safety hazard of human hands touching the machine during feeding.

[0022] The clamping assembly 8 includes an I-beam guide plate 81, a movable block 82 movably connected to the upper surface of the I-beam guide plate 81, and a guide plate 83 fixedly connected to the upper surface of the movable block 82. A guide seat 84 is fixedly connected to the outer surface of the movable block 82, and a screw 85 is movably connected to the inside of the guide seat 84.

[0023] A rotating handle 86 is fixedly connected to the end of the screw 85 away from the guide seat 84. The screw 85 is movably connected to the side surface of the I-beam guide plate 81 through the rotating handle 86. The movable block 82 and the guide plate 83 are movably connected to the upper surface of the I-beam guide plate 81 in two sets. The guide plate 83 is crescent-shaped.

[0024] In use, after adjusting the position of the adjusting seat 6, the pre-positioning of the welded pipe is achieved through the clamping assembly 8 on its top: rotating the rotating handle 86 drives the screw 85 to rotate smoothly along the guide seat 84. The screw 85 drives the two sets of movable blocks 82 to move synchronously in opposite directions along the guide rail of the I-beam guide plate 81 through threaded transmission, thereby precisely adjusting the distance between the two sets of crescent-shaped guide plates 83. The arc-shaped structure of the crescent-shaped guide plate 83 is adapted to the contour height of the outer wall of the welded pipe, and can closely fit the surface of welded pipes of different diameters, achieving precise centering and positioning of the welded pipe, while avoiding squeezing damage to the surface of the welded pipe during clamping.
