Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a support tooling for steel pipe processing. Background Technique

[0002] A steel pipe refers to a steel product with a hollow cross-section, whose length is much greater than its diameter or circumference. Steel pipes are not only used for transporting fluids and powdered solids, exchanging heat energy, manufacturing mechanical parts and containers, but also an economical steel product. Using steel pipes to manufacture building structure grids, supports and mechanical brackets can reduce the weight, save 20 - 40% of metal, and can achieve factory mechanized construction. Using steel pipes to manufacture highway bridges can not only save steel, simplify construction, but also greatly reduce the area of the coating protection layer, saving investment and maintenance costs. During the production process of steel pipes, such as cutting, welding, painting, etc., it is necessary to support their positions, which can facilitate the operation during later processing, and such equipment is usually used to effectively support the steel pipes to ensure safety during transportation.

[0003] For example, the Chinese patent with the publication number CN218657856U discloses a support device for circular steel pipe processing, including a bottom plate and a sliding seat. On the upper surface of the bottom plate, side baffles are symmetrically and fixedly installed on the left and right by fixing rods. A servo motor is arranged at the rear end of the bottom plate. A limiting block is clamped and installed at the front end of the bottom plate. An arc-shaped clamp is rotatably installed on the upper part of the limiting block. The sliding seat is slidably installed on the upper part of the bottom plate. Two groups of inclined abutting blocks are symmetrically and movably installed on the upper part of the sliding seat. A number of rolling beads are rotatably installed on the inclined surfaces of the inclined abutting blocks.

[0004] In this patent, the movably installed arc-shaped clamp is used to limit one end of the circular steel pipe, and the servo motor controls the rotation of the lead screw, thereby driving the sliding seat to slide on the upper part of the bottom plate. The clamping grooves opened on the left and right sides of the sliding seat are fitted with the side baffles, which increases the stability of the sliding seat movement and avoids instability when the sliding seat moves and raises one end of the circular pipe, causing the circular pipe to shake. However, when it is necessary to support steel pipes of different specifications and sizes, it cannot be guaranteed that the arc-shaped clamp can fit on the surface of the steel pipe. If the arc-shaped clamp is to support steel pipes of different sizes, arc-shaped clamps of different sizes need to be matched, which results in certain limitations for the specifications and sizes of the steel pipes supported by this patent. Moreover, the specification size of the bottom plate in this patent is relatively long, the production cost is high, and it occupies a lot of space. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is: to overcome the defects of the prior art, provide a support tooling for steel pipe processing, which can adapt to steel pipes of different specifications and sizes and the heights required for processing, has a simple structure and does not occupy space.

[0006] To solve the above technical problems, the technical solution of the present utility model is as follows: A support tooling for steel pipe processing, which is installed on the corresponding steel pipe processing equipment, includes a base. Two groups of symmetrically arranged support members are provided on the base. Two mounting plates are fixedly provided on the base. The support member includes a support cylinder rotatably installed on the mounting plate and a support column slidably arranged in the support cylinder. A rotatable support roller is provided at the top of the support column.

[0007] Further, the two mounting plates are symmetrically arranged on the base, and the mounting plates are perpendicular to the base. The two support cylinders are respectively rotatably installed on one side of the two mounting plates close to each other.

[0008] Further, a mounting seat is fixedly provided on the mounting plate. Two connecting shafts are fixedly provided on both sides of the bottom of the support cylinder. The other ends of the two connecting shafts are rotatably installed on the mounting seat.

[0009] Further, a sliding groove is formed on one side of the support cylinder. A sliding strip matching the sliding groove is fixedly provided on the support column.

[0010] Further, a driving cylinder for driving the support column to slide relative to the support cylinder is provided on the support cylinder. The cylinder body of the driving cylinder is fixedly installed on the outer wall of the side of the support cylinder where the sliding groove is formed. The sliding strip on the support column passes through the sliding groove and extends outside the support cylinder. The output end of the driving cylinder is fixedly connected to the sliding strip.

[0011] Further, an electric push rod for driving the support cylinder to rotate relative to the base is fixedly provided on the mounting plate. The output end of the electric push rod is rotatably connected to the support cylinder through a connecting member.

[0012] Further, the connecting member includes a connecting seat fixedly installed at the output end of the electric push rod, a rotating seat fixedly installed on the side wall of the support cylinder, and a connecting rod. The two ends of the connecting rod are respectively rotatably connected to the connecting seat and the rotating seat.

[0013] Further, a mounting groove for installing the support roller is formed at the top of the support column. A mounting rod is fixedly provided in the mounting groove. The mounting rod is perpendicular to the axial direction of the support column. The support roller is rotatably sleeved on the mounting rod.

[0014] Further, mounting ears are fixedly provided on both sides of the base.

[0015] By adopting the above technical solution, the present utility model has the following beneficial effects:

[0016] 1. Through the coordinated action of the electric push rod and the driving cylinder, the support rollers at the tops of the two support columns are attached to the outer wall of the steel pipe to support the steel pipe. This enables the support rollers to always be attached to the outer wall of the steel pipe to support the steel pipe regardless of the size specifications of the steel pipe.

[0017] 2. The number and spacing of the supporting tooling installed on the processing equipment can be adjusted according to the length of the steel pipe to ensure the supporting strength and effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the content of the present utility model easier to be clearly understood, the present utility model will be further described in detail below according to specific embodiments and in conjunction with the accompanying drawings.

[0027] As Figures 1-4 shown, in this embodiment, a supporting tooling for steel pipe processing is provided, which is installed on the corresponding steel pipe 100 processing equipment, and includes a base 1. There are two sets of symmetrically arranged support members 2 on the base 1. The support members 2 are rotatable relative to the base 1. The support members 2 include a support cylinder 4 rotatably installed on the base 1 and a support column 5 slidably arranged in the support cylinder 4. A rotatable support roller 6 is provided at the top of the support column 5.

[0028] As Figures 1-4As shown in the figure, in this embodiment, two mounting plates 3 are fixedly provided on the base 1. The two mounting plates 3 are symmetrically arranged on the base 1. Two support cylinders 4 are respectively rotatably mounted on one side of the two mounting plates 3 close to each other. Specifically, the mounting plate 3 is perpendicular to the base 1. A mounting seat 31 is fixedly provided on the mounting plate 3. Two connecting shafts (not shown in the figure) are fixedly provided on both sides of the bottom of the support cylinder 4. The other ends of the two connecting shafts are rotatably mounted on the mounting seat 31, so that the support cylinder 4 can rotate relative to the mounting plate 3.

[0029] As Figures 1-4 shown in the figure, in this embodiment, a sliding groove 41 is provided on one side of the support cylinder 4. A sliding bar 51 matching the sliding groove 41 is fixedly provided on the support column 5, so that the support column 5 can slide in the support cylinder 4. The support column 5 is a cylindrical structure matching the support cylinder 4. The outer diameter of the support column 5 corresponds to the inner diameter of the support cylinder 4 to prevent the support column 5 from shaking when sliding due to the gap between the support column 5 and the support cylinder 4.

[0030] As Figures 1-4 shown in the figure, in this embodiment, a driving cylinder 7 for driving the support column 5 to slide relative to the support cylinder 4 is provided on the support cylinder 4. The cylinder body of the driving cylinder 7 is fixedly installed on the outer wall of the support cylinder 4. Specifically, the cylinder body of the driving cylinder 7 is located on the outer wall of the side of the support cylinder 4 where the sliding groove 41 is provided. The sliding bar 51 on the support column 5 passes through the sliding groove 41 and extends outside the support cylinder 4. The output end of the driving cylinder 7 is fixedly connected to the sliding bar 51 of the support column 5, so that the output end of the driving cylinder 7 can drive the support column 5 to move in the support cylinder 4 when it extends or retracts.

[0031] As Figures 1-4 shown in the figure, in this embodiment, an electric push rod 8 for driving the support cylinder 4 to rotate relative to the base 1 is fixedly provided on the mounting plate 3. The output end of the electric push rod 8 is rotatably connected to the support cylinder 4. The output end of the electric push rod 8 extending or retracting can drive the support cylinder 4 to rotate relative to the base 1, so that the support rollers 6 at the tops of the two support columns 5 approach or move away from each other, thereby adjusting the distance between the two groups of support members 2 to adapt to steel pipes 100 of different sizes.

[0032] As Figures 1-4As shown, in this embodiment, the output end of the electric push rod 8 is rotatably connected to the support cylinder 4 through a connecting member 9. The connecting member 9 includes a connecting seat 91 fixedly installed at the output end of the electric push rod 8, a rotating seat 92 fixedly installed on the side wall of the support cylinder 4, and a connecting rod 93. One end of the connecting rod 93 is rotatably connected to the connecting seat 91, and the other end of the connecting rod 93 is rotatably connected to the rotating seat 92. When the electric push rod 8 works, its output end drives the connecting seat 91 to extend or retract, causing the connecting rod 93 to rotate relative to the connecting seat 91 and the rotating seat 92. At the same time, the connecting rod 93 can drive the rotating seat 92 and the support cylinder 4 to rotate relative to the base 1.

[0033] As Figures 1-4 shown, in this embodiment, the top of the support column 5 is provided with an installation groove 52 for installing the support roller 6. An installation rod 53 is fixedly provided in the installation groove 52. The installation rod 53 is perpendicular to the axial direction of the support column 5. The support roller 6 is rotatably sleeved on the installation rod 53.

[0034] As Figures 1-4 shown, in this embodiment, the electric push rod 8 drives the support cylinder 4 to rotate relative to the base 1, causing the support rollers 6 at the tops of the two support columns 5 to approach or move away from each other. Driving the support column 5 to move in the support cylinder 4 by the driving cylinder 7 can also cause the support rollers 6 at the tops of the two support columns 5 to approach or move away from each other. At the same time, the height of the support rollers 6 at the tops of the two support columns 5 from the base 1 changes. Through the coordinated action of the electric push rod 8 and the driving cylinder 7, the support rollers 6 at the tops of the two support columns 5 can be attached to the outer wall of the steel pipe 100 to support the steel pipe 100, thereby adapting to steel pipes 100 of different specifications and sizes.

[0035] As Figures 1-4 shown, in this embodiment, mounting ears 11 are fixedly provided on both sides of the base 1 so that the base 1 can be installed on the corresponding steel pipe 100 processing equipment.

[0036] The working process and principle of the present utility model are as follows: When in use, one end of the steel pipe 100 needs to be fixed by a clamping mechanism on the corresponding processing equipment. Since the sizes of the steel pipes 100 are different, the height of the axis from the base 1 and the distance between the outer wall of the steel pipe 100 and the two supporting rollers 6 are different. This requires adjusting the two groups of supporting members 2 so that the two supporting rollers 6 can fit on the outer wall of the steel pipe 100 to support the steel pipe 100. Specifically, the base 1 is installed on the corresponding steel pipe 100 processing equipment, and one end of the steel pipe is fixed on the corresponding processing equipment. The electric push rod 8 works, and the output end of the electric push rod 8 extends or retracts to drive the support cylinder 4 to rotate relative to the base 1. Subsequently, the driving cylinder 7 works, and when the output end of the driving cylinder 7 extends or retracts, it drives the support column 5 to move in the support cylinder 4. When the support cylinder 4 rotates and the support column 5 slides, the support rollers 6 at the tops of the two support columns 5 approach or move away from each other. At the same time, the height of the support rollers 6 at the tops of the two support columns 5 from the base 1 changes. Through the coordinated actions of the electric push rod 8 and the driving cylinder 7, the support rollers 6 at the tops of the two support columns 5 are made to fit against the side wall of the steel pipe 100 to support the subsequent work of the steel pipe 100. This enables the support rollers 6 to always fit on the outer wall of the steel pipe 100 to support the steel pipe 100 regardless of the size specifications of the steel pipe 100. At the same time, the number and spacing of the supporting tooling installed on the processing equipment can be adjusted according to the length of the steel pipe 100 to ensure the supporting strength and effect.

[0037] In the specific embodiments described above, the technical problems solved, technical solutions, and beneficial effects of the present utility model are further described in detail. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
