Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, specifically to a device for equal-quantity cutting of steel pipes for scaffolding processing. Background Technology

[0002] Scaffolding is a working platform used in construction. It is generally used for exterior walls, interior decoration, or places where the floor height is too high for direct construction. Because steel pipes have advantages such as light weight, high strength, corrosion resistance, and wear resistance, they are often used to make scaffolding. Before making scaffolding, steel pipes are cut into appropriate sizes using professional cutting equipment. Then, the cut steel pipes are welded and assembled according to requirements to obtain the scaffolding.

[0003] Current steel pipe cutting devices have the following drawbacks: After the steel pipe is cut, debris remains at the cut edge. This debris is usually cleaned manually or by setting up an additional cleaning device, which not only complicates the mechanism but also makes the operation cumbersome. If the steel pipe material is not derusted or degreased before cutting, it will not only affect the cutting effect but also produce harmful fumes. In addition, it will contaminate the cut edge of the steel pipe and affect its service life.

[0004] To address the above issues, a device for equal-quantity cutting of steel pipes for scaffolding processing is proposed. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This solution utilizes a cleaning component to remove contaminants from the steel pipe before cutting, ensuring a high-quality cut. Furthermore, removing contaminants prevents the generation of harmful fumes due to oxidation during the cutting process, thus avoiding any impact from contaminants on the cutting. Simultaneously, after cutting, the solution automatically cleans up debris from the cut surface, eliminating the need for manual debris removal, reducing labor costs, and improving work efficiency.

[0018] 2. By combining the cleaning and spraying components, the solvent contained in the storage tank is sprayed onto the annular brush. While cleaning debris from the surface of the steel pipe cutting area, the annular brush also coats the surface of the steel pipe cutting area with solvent for further cleaning. This helps maintain a better cutting effect and reduces the probability of contamination of the steel pipe cut section, thus not affecting the service life of the steel pipe.

[0019] 3. By combining the cutting component, cleaning component, and connecting component, this invention allows for switching between single and multiple cleaning cycles based on varying amounts of rust and oil residue. This not only achieves better cleaning results but also improves cutting performance. Furthermore, the multiple cleaning cycles are not achieved through the reciprocating rotation of the cutting machine, which helps reduce equipment wear. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To address the technical issues of residual debris at the cut edge of steel pipe 20, and the fact that steel pipe 20 was not derusted or degreased before cutting, thus affecting cutting results and the service life of steel pipe 20, such as... Figures 1-8 and Figure 11 As shown, the following preferred technical solutions are provided:

[0035] A scaffolding processing steel pipe equal-quantity segment cutting device includes a workbench 1 and a feeding assembly 2 mounted on the workbench 1. A pair of clamping assemblies 3 are fixedly mounted on the feeding assembly 2, and a pair of clamping assemblies 4 are mounted on the workbench 1. Steel pipes 20 are clamped on the clamping assemblies 3 and 4. The feeding assembly 2 and clamping assemblies 3 cooperate to convey the steel pipes 20 forward, enabling continuous cutting of the steel pipes 20 without manual feeding, saving manpower. A cutting assembly 5 is mounted on the workbench 1, capable of cutting the steel pipes 20 into multiple segments as required. A support assembly 6 is fixedly mounted on the workbench 1, and a cleaning assembly 7 is slidably mounted on the support assembly 6. The support assembly 6 limits the movement of the cleaning assembly 7, allowing it to clean along a preset trajectory. A pair of liquid sprayers are mounted on the cleaning assembly 7. Component 8, a liquid storage tank 10 is fixedly installed on the workbench 1. The liquid storage tank 10 is connected to a pair of spraying components 8 through liquid pipes. The liquid storage tank 10 contains rust-removing oil or degreasing solvent or other solvents. The appropriate solvent can be selected according to the actual production process. During the operation of the cleaning component 7, it will drive the spraying component 8 to operate. The spraying component 8 draws out the solvent contained in the liquid storage tank 10 and sprays it on the cleaning part of the cleaning component 7 to remove rust or dirt from the surface of the cutting part of the steel pipe 20, which is beneficial to the subsequent cutting operation. A connecting component 9 is fixedly installed on the cutting component 5, and the end of the connecting component 9 away from the cutting component 5 is movably installed on the cleaning component 7. An electric telescopic column 30 is also fixedly installed on the workbench 1, and the electric telescopic column 30 is located directly below the cleaning component 7.

[0036] When the cutting component 5 starts cutting, it drives the cleaning component 7 to operate on the support component 6 via the connecting component 9. This pre-treats the surface of the steel pipe 20 to be cut, removing rust or dirt. Then, the cutting component 5 cuts the steel pipe 20 to ensure a good cutting effect. This not only reduces the amount of harmful fumes generated but also prevents the cut of the steel pipe 20 from being contaminated, minimizing the possibility of situations affecting the service life of the steel pipe 20. If the rust or oil on the surface of the steel pipe 20 is thick and cannot be treated in one go, the cutting component 5 does not need to drive the cleaning component 7 to reciprocate on the support component 6. Instead, the electric telescopic column 30 drives the cleaning component 7 to reciprocate on the support component 6 multiple times until it is clean before cutting, ensuring good cutting quality.

[0037] The feeding assembly 2 includes a bracket 21 fixedly installed on the top surface of the workbench 1. A bracket 22 is also fixedly installed on the top surface of the workbench 1. A pair of limiting rods 23 are symmetrically fixedly installed on the bracket 21 and the bracket 22. A slide table 24 is slidably installed through the pair of limiting rods 23. A pair of clamping assemblies 3 are symmetrically fixedly installed on the slide table 24. An electric telescopic column 25 is fixedly installed on the bracket 21, and the output end of the electric telescopic column 25 is fixedly connected to the side wall of the slide table 24.

[0038] In actual production, the steel pipe 20 is placed on a bracket (not shown in the figure). After one end of the steel pipe 20 is clamped by the two clamping components 1 3, the electric telescopic column 25 is extended. The electric telescopic column 25 pushes the slide table 24 to slide on the limit rod 23. During the sliding of the slide table 24, the two clamping components 1 3 and the steel pipe 20 will move synchronously with the slide table 24 until the end of the steel pipe 20 is clamped by the two clamping components 2 4. The electric telescopic column 25 stops extending, and then the steel pipe 20 is cut. After the cutting is completed, the worker removes the clamping components. The cut workpiece is removed from part 24, and then the two clamping components 13 are released and detached from the steel pipe 20. The electric telescopic column 25 drives the slide table 24 and the clamping components 13 to retract. When it retracts to the appropriate position, the two clamping components 13 clamp the steel pipe 20 again. The electric telescopic column 25 is activated again to extend and transport the steel pipe 20 to the clamping component 24 for clamping. This process is repeated to continuously extract the steel pipe 20 from the bracket (not shown in the figure), realizing continuous feeding operation without the need for manual feeding. This not only has high efficiency but also saves manpower.

[0039] The cutting assembly 5 includes a mounting base 51 fixedly installed on the top surface of the workbench 1. A cutting machine 52 is rotatably mounted on the mounting base 51. An electric telescopic column 3 53 is also fixedly installed on the top surface of the workbench 1. The output end of the electric telescopic column 3 53 is rotatably connected to the cutting machine 52. When cutting the steel pipe 20, the cutting machine 52 is started and then the electric telescopic column 3 53 controls the cutting machine 52 to rotate, so that the blade on the cutting machine 52 contacts the steel pipe 20, thereby achieving the cutting effect. After the cutting is completed, the electric telescopic column 3 53 can also control the cutting machine 52 to rotate and reset for the next cutting operation.

[0040] The support assembly 6 includes a mounting frame 61 fixedly installed on the top surface of the workbench 1. The two inner side walls of the mounting frame 61 are respectively provided with vertical sliding grooves 62, and the crossbeam plate of the mounting frame 61 is provided with vertical sliding grooves 64.

[0041] The cleaning assembly 7 includes a U-shaped frame 71 slidably mounted on a slide rail 62. The bottom surface of the U-shaped frame 71 is elastically connected to the side wall of the inner cavity of the slide rail 62 by a spring 63. The spring 63 can realize the reset operation of the U-shaped frame 71. Compression rods 72 are fixedly installed on the two side walls of the upper part of the U-shaped frame 71, and the two compression rods 72 are symmetrically arranged. The compression rods 72 have compression properties and can be compressed during the cleaning process to adapt to the apparent shape of the steel pipe 20. An annular brush 73 is rotatably installed in the end of the compression rod 72 away from the U-shaped frame 71. A motor 74 is fixedly installed on the side wall of one end of the frame 71. The output end of the motor 74 is fixedly connected to the side wall of the annular brush 73. The motor 74 is used to drive the annular brush 73 to rotate at high speed to achieve a cleaning effect. A spray nozzle 75 is fixedly installed on the top surface of the end of the compression rod 72 away from the U-shaped frame 71. The spray nozzle 75 and the spray assembly 8 are connected by liquid pipes. The spray nozzle 75 can spray the solvent in the spray assembly 8 onto the annular brush 73. During the cleaning process, it can effectively remove rust and dirt from the surface of the cut part of the steel pipe 20 to ensure a good cutting effect.

[0042] The compression rod 72 includes a fixed rod 721, with a slide rail 722 inside the fixed rod 721. A top rod 723 is slidably installed inside the slide rail 722. The side wall of the top rod 723 is elastically connected to the side wall of the inner cavity of the slide rail 722 by a spring 724. The annular brush 73, the motor 74, and the spray nozzle 75 are all mounted on the top rod 723.

[0043] The connecting component 9 includes a vertical connecting rod 91 fixedly installed on the cutting machine 52, a horizontal connecting rod 92 snapped onto the vertical connecting rod 91, and a collar 93 fixedly installed at the end of the horizontal connecting rod 92 away from the vertical connecting rod 91. The collar 93 is movably sleeved on the convex shaft on the side wall of the U-shaped frame 71, and the convex shaft is slidably disposed in the inner cavity of the slide groove 64.

[0044] Specifically, firstly, by cooperating with the feeding component 2 and the clamping component 3, the steel pipe 20 is conveyed forward to a suitable position, and the steel pipe 20 is clamped by the clamping component 4, thus fixing the steel pipe 20. When cutting the steel pipe 20 begins, the cutting machine 52 is started, and then the electric telescopic column 3 53 is extended. The electric telescopic column 3 53 will drive the cutting machine 52 to rotate on the mounting base 51 towards the steel pipe 20. During the rotation of the cutting machine 52, the cutting machine 52 will drive the U-shaped frame through the vertical connecting rod 91, the horizontal connecting rod 92 and the collar 93. 71 slides downward in the first slide groove 62. In the initial state, the two annular brushes 73 are located on the upper part of the steel pipe 20. Due to the curvature of the steel pipe 20, as the U-shaped frame 71 slides downward, the top rod 723 is pressed into the slide groove 722. Under the elastic force of the second spring 724, the annular brushes 73 on the top rod 723 are always in contact with the outer wall of the steel pipe 20. Then, the motor 74 drives the annular brushes 73 to rotate at high speed, which can remove rust or dirt from the surface of the cutting part of the steel pipe 20, prevent it from affecting the cutting effect, and help improve the cutting quality.

[0045] Furthermore, after the steel pipe 20 is cut, the two annular brushes 73 are positioned at the lower part of the steel pipe 20. The electric telescopic column 53 retracts and drives the cutting machine 52 to rotate and reset on the mounting base 51. During the reset process, the cutting machine 52 drives the U-shaped frame 71 to slide upward in the slide groove 62 through the vertical connecting rod 91, the horizontal connecting rod 92 and the collar 93. During the sliding process, the annular brushes 73 clean the debris at the cut, eliminating the need to reset the cleaning mechanism in subsequent sections or to perform manual cleaning.

[0046] As described above, before using the cutting machine 52 to cut the steel pipe 20, the present invention first removes rust or dirt from the surface of the steel pipe 20 to be cut. Then, the cutting machine 52 can immediately cut the cleaned part without the need for a separate cleaning process at the beginning. Even if a separate cleaning process is set up at the beginning, the surface of the steel pipe 20 will still be contaminated during the cutting process, resulting in repetitive work. The present invention, however, only cleans the cut part of the steel pipe 20. After the cutting is completed, a unified cleaning is performed, avoiding the phenomenon of repetitive work. Moreover, during the resetting process after cutting, the debris at the cut can also be cleaned. The present invention has a high degree of integration, simple structure, and strong practicality.

[0047] To address the technical problem that the annular brush 73 alone cannot quickly clean the oil and rust from the cut surface of the steel pipe 20, such as... Figures 6-7 As shown, the following preferred technical solutions are provided:

[0048] The spray assembly 8 includes a piston cylinder 81 fixedly mounted on the top surface of a fixed rod 721. A piston 82 is slidably mounted inside the piston cylinder 81. An L-shaped connecting rod 83 is fixedly mounted on the side wall of the piston 82. The end of the L-shaped connecting rod 83 away from the piston 82 is fixedly mounted on the top surface of a top rod 723. A one-way inlet valve 84 and a one-way outlet valve 85 are respectively fixedly mounted on the side wall of the piston cylinder 81. The one-way inlet valve 84 is connected to the liquid storage tank 10 through a liquid pipe, and the one-way outlet valve 85 is connected to the spray nozzle 75 through a liquid pipe.

[0049] Specifically, as the push rod 723 retracts into the slide rail 722, it compresses the solvent inside the piston cylinder 81 via the L-shaped connecting rod 83 and the piston 82. The compressed solvent then enters the spray nozzle 75 through the one-way outlet valve 85 and the liquid pipe, ultimately being sprayed onto the annular brush 73. This allows the annular brush 73 to simultaneously clean the surface of the cut section of the steel pipe 20 and coat the surface with solvent, thus cleaning the cut surface and protecting it. It maintains a good cutting effect and can reduce the probability of contamination of the cut section of the steel pipe 20, thus not affecting the service life of the steel pipe 20; under the elastic force of the spring 724, when the push rod 723 extends outward toward the slide 722, the push rod 723 will move in the opposite direction in the inner cavity of the piston cylinder 81 through the L-shaped connecting rod 83, and draw the solvent contained in the storage tank 10 into the piston cylinder 81 through the liquid pipe for the next use. By repeating the above operation, continuous and automatic liquid spraying operation can be achieved.

[0050] To address the technical problem that the annular brush 73 cannot thoroughly clean the surface of the cut area of ​​the steel pipe 20 after a single cleaning cycle, such as... Figures 9-12 As shown, the following preferred technical solutions are provided:

[0051] The vertical connecting rod 91 includes a vertical connecting rod body 911 fixedly installed on the cutting machine 52. A sliding groove 912 is provided on the side wall of the vertical connecting rod body 911. An installation groove 913 is provided on two opposite side walls in the inner cavity of the sliding groove 912. A locking block 914 is slidably installed in the inner cavity of the installation groove 913. The side wall of the locking block 914 and the side wall of the inner cavity of the installation groove 913 are elastically connected by a spring 915. An electromagnet 916 is fixedly installed on the side wall of the inner cavity of the installation groove 913. A permanent magnet 917 is fixedly installed on the side wall of the locking block 914 facing the electromagnet 916. The electromagnet 916 and the permanent magnet 917 are aligned. A circular groove 918 is also provided on two opposite side walls in the inner cavity of the sliding groove 912.

[0052] The transverse connecting rod 92 includes a transverse connecting rod body 921, which is fixedly connected to a collar 93. A slot 922 is provided at one end of the transverse connecting rod body 921 near the vertical connecting rod body 911. A locking block 914 can be engaged with the slot 922. Rotating shafts 923 are fixedly installed on the outer walls of both sides of the transverse connecting rod body 921 near the vertical connecting rod body 911. The rotating shafts 923 are rotatably disposed in the inner cavity of the circular groove 918.

[0053] Specifically, during the cutting process of steel pipe 20, if the worker finds a lot of rust or oil on the surface of the cut part of steel pipe 20, the electromagnet 916 is energized, causing the electromagnet 916 to attract the permanent magnet 917 and pull the locking block 914 into the inner cavity of the mounting groove 913. At this time, the locking relationship between the locking block 914 and the locking groove 922 is released. With the cooperation of the rotating shaft 923 and the circular groove 918, the collar 93 and the transverse connecting rod 92 can rotate on the vertical connecting rod 91. Then, the electric telescopic column 30 is activated to push the U-shaped frame 71 to reciprocate up and down in the slide groove 62. During the reciprocating motion of the U-shaped frame 71, due to the collar 93 and the transverse connecting rod 917, the U-shaped frame 71 rotates up and down. 2. The entire assembly can rotate on the vertical connecting rod 91, so that the horizontal connecting rod 92 and the collar 93 will not interfere with the operation of the U-shaped frame 71. The surface of the steel pipe 20 cutting part can be cleaned multiple times by the annular brush 73 to ensure that the cutting part is clean. After cleaning, the electric telescopic column 30 is reset, and the U-shaped frame 71, the collar 93 and the horizontal connecting rod 92 are reset synchronously. At this time, the electromagnet 916 is de-energized. Under the elastic force of the spring 3 915, the locking block 914 is locked into the locking groove 922. At this time, the collar 93 and the horizontal connecting rod 92 cannot rotate on the vertical connecting rod 91. So when the cutting machine 52 is flipped, the cleaning assembly 7 can still be driven to operate through the vertical connecting rod 91, the horizontal connecting rod 92 and the collar 93.

[0054] By setting up the above, and selecting between single-cleaning and multiple-cleaning according to different amounts of rust and oil residue, a better cleaning effect can be achieved, which is beneficial to improving the cutting effect, rather than achieving multiple cleanings by repeatedly rotating the cutting machine 52, which helps to reduce equipment wear.
