Description

Technical Field

[0001] The present invention relates to the technical field of metal cutting, and particularly to an equal-length cutting device for steel pipes used in scaffolding processing. Background Art

[0002] A scaffolding is a working platform for building construction, generally used for exterior walls, interior decoration, or places with high floors where direct construction is not possible. Since steel pipes have the advantages of light weight, high strength, corrosion resistance, and wear resistance, steel pipes are often used to make scaffolding. Before making the scaffolding, professional cutting devices are used to cut the steel pipes into appropriate sizes, and then the cut steel pipes are welded and assembled as required to obtain the scaffolding.

[0003] The current steel pipe cutting devices have the following defects: after the steel pipe is cut, there are residues at the cut of the steel pipe. Generally, the residues are cleaned manually or an additional set of cleaning devices is provided, which not only makes the mechanism complex but also makes the operation cumbersome; if the steel pipe material is not rust-removed or degreased before cutting, it will not only affect the cutting effect but also generate harmful fumes. In addition, it will pollute the cut of the steel pipe and affect the service life of the steel pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] To solve the technical problems that there are chips remaining at the cut of the steel pipe 20, and the steel pipe 20 is not rust-removed or degreased before cutting, which affects the cutting effect and the service life of the steel pipe 20, as Figures 1-8 and Figure 11 shown, the following preferred technical solutions are provided: A device for equally cutting steel pipes for scaffolding processing, including a workbench 1 and a feeding component 2 arranged on the workbench 1. A pair of clamping components one 3 are fixedly arranged on the feeding component 2. A pair of clamping components two 4 are arranged on the workbench 1. The steel pipe 20 is clamped by the clamping component one 3 and the clamping component two 4. The feeding component 2 is cooperatively arranged with the clamping component one 3 and can convey the steel pipe 20 forward to realize the continuous cutting operation of the steel pipe 20 without manual feeding, saving manpower. A cutting component 5 is arranged on the workbench 1. The cutting component 5 can cut the steel pipe 20 into multiple segments according to requirements. A supporting component 6 is fixedly arranged on the workbench 1. A cleaning component 7 is slidably arranged on the supporting component 6. The supporting component 6 is used to limit the cleaning component 7 so that the cleaning component 7 can be cleaned according to a preset track. A pair of liquid spraying components 8 are arranged on the cleaning component 7. A liquid storage tank 10 is fixedly installed on the workbench 1. The liquid storage tank 10 and the pair of liquid spraying components 8 are respectively communicated through liquid pipes. The liquid storage tank 10 contains rust-removing oil or a degreasing solvent or other solvents, and a suitable solvent can be selected according to the actual production process. During the operation of the cleaning component 7, it will drive the liquid spraying component 8 to operate. The liquid spraying component 8 pumps 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 on 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 arranged on the cutting component 5, and one end of the connecting component 9 away from the cutting component 5 is movably arranged on the cleaning component 7. An electric telescopic column one 30 is also fixedly arranged on the workbench 1, and the electric telescopic column one 30 is arranged directly below the cleaning component 7.

[0023] When the cutting assembly 5 starts cutting, it will drive the cleaning assembly 7 to operate on the support assembly 6 through the connecting assembly 9, pre-treat the surface of the cutting part of the steel pipe 20 to remove rust or dirt, and then cut the steel pipe 20 through the cutting assembly 5 to ensure good subsequent cutting effects. This can not only reduce the generation amount of harmful smoke, but also prevent the cut of the steel pipe 20 from being contaminated, and as much as possible avoid the situation that affects the service life of the steel pipe 20. If the rust on the surface of the cutting part of the steel pipe 20 is thick or there is a lot of oil stain and it cannot meet the requirements after one treatment, it is not necessary for the cutting assembly 5 to drive the cleaning assembly 7 to reciprocate on the support assembly 6. Instead, the electric telescopic column one 30 drives the cleaning assembly 7 to reciprocate on the support assembly 6 multiple times until it is cleaned and then cut to ensure good cutting quality.

[0024] The feeding assembly 2 includes a bracket one 21 fixedly installed on the top surface of the workbench 1. A bracket two 22 is also fixedly installed on the top surface of the workbench 1. A pair of limit rods 23 are symmetrically and fixedly installed on the bracket one 21 and the bracket two 22. A sliding table 24 is slidably installed through the pair of limit rods 23. A pair of clamping assemblies one 3 are symmetrically and fixedly installed on the sliding table 24. An electric telescopic column two 25 is fixedly installed on the bracket one 21, and the output end of the electric telescopic column two 25 is fixedly connected to the side wall of the sliding table 24.

[0025] In the actual production process, the steel pipe 20 is placed on a bracket (not shown in the figure). After the two clamping assemblies one 3 clamp one end of the steel pipe 20, start the electric telescopic column two 25 to extend. The electric telescopic column two 25 pushes the sliding table 24 to slide on the limit rods 23. During the sliding process of the sliding table 24, the two clamping assemblies one 3 and the steel pipe 20 will move synchronously with the sliding table 24 until the end of the steel pipe 20 is clamped by the two clamping assemblies two 4. Then the electric telescopic column two 25 stops extending, and then the cutting operation is carried out on the steel pipe 20. After cutting is completed, the worker removes the cut workpiece on the clamping assembly two 4. Then the two clamping assemblies one 3 are loosened and separated from the steel pipe 20. The electric telescopic column two 25 drives the sliding table 24 and the clamping assembly one 3 to retract. When it retracts to a suitable position, the two clamping assemblies one 3 clamp the steel pipe 20 again. Start the electric telescopic column two 25 to extend again, and convey the steel pipe 20 to the clamping assembly two 4 for clamping. In this way, the steel pipe 20 on the bracket (not shown in the figure) can be continuously drawn out, realizing the operation of continuous feeding. There is no need for manual feeding, which is not only highly efficient but also saves manpower.

[0026] 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 installed on the mounting base 51. An electric telescopic column three 53 is also fixedly installed on the top surface of the workbench 1, and the output end of the electric telescopic column three 53 is rotatably connected to the cutting machine 52. When cutting the steel pipe 20, start the cutting machine 52 to operate, and then control the cutting machine 52 to flip through the electric telescopic column three 53, so that the blade on the cutting machine 52 contacts the steel pipe 20, thereby achieving the cutting effect. When the cutting is completed, the cutting machine 52 can also be controlled to flip and reset through the electric telescopic column three 53 for the next cutting operation.

[0027] The support assembly 6 includes a mounting frame 61 fixedly installed on the top surface of the workbench 1. A chute one 62 is vertically opened on each of the two inner side walls of the mounting frame 61, and a chute two 64 is vertically opened on the crossbeam plate of the mounting frame 61.

[0028] The cleaning assembly 7 includes a U-shaped frame 71 slidably installed on the chute one 62. The bottom surface of the U-shaped frame 71 is elastically connected to the side wall of the inner cavity of the chute one 62 through a spring one 63. The spring one 63 can realize the reset operation of the U-shaped frame 71. Compression rods 72 are respectively fixedly installed on the two side walls of the upper part of the U-shaped frame 71, and the two compression rods 72 are arranged symmetrically. The compression rod 72 has a compression performance and can be compressed during the cleaning process to adapt to the apparent shape of the steel pipe 20. A ring brush 73 is rotatably installed inside 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 the end of the compression rod 72 away from the U-shaped frame 71, and the output end of the motor 74 is fixedly connected to the side wall of the ring brush 73. The motor 74 is used to drive the ring brush 73 to rotate at a high speed to achieve the cleaning effect. A liquid spraying port 75 is fixedly installed on the top surface of the end of the compression rod 72 away from the U-shaped frame 71. The liquid spraying port 75 and the liquid spraying assembly 8 are respectively connected through a liquid pipe. The liquid spraying port 75 can spray the solvent in the liquid spraying assembly 8 on the ring brush 73, and can effectively remove rust and dirt on the surface of the cutting part of the steel pipe 20 during the cleaning process to ensure a good cutting effect.

[0029] The compression rod 72 includes a fixed rod 721. A slideway 722 is opened inside the fixed rod 721. A top rod 723 is slidably installed in the slideway 722. The side wall of the top rod 723 is elastically connected to the side wall of the inner cavity of the slideway 722 through a spring two 724. The ring brush 73, the motor 74 and the liquid spraying port 75 are all arranged on the top rod 723.

[0030] The connecting component 9 includes a vertical connecting rod 91 fixedly installed on the cutting machine 52. A horizontal connecting rod 92 is clamped on the vertical connecting rod 91. A collar 93 is fixedly installed at one 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 arranged in the inner cavity of the second chute 64.

[0031] Specifically, first, through the cooperation of the feeding component 2 and the first clamping component 3, the steel pipe 20 can be conveyed forward to a suitable position, and the steel pipe 20 is clamped by the second clamping component 4. At this time, the fixation of the steel pipe 20 is achieved; when starting to cut the steel pipe 20, start the cutting machine 52, and then start the electric telescopic column three 53 to extend. The electric telescopic column three 53 will drive the cutting machine 52 to turn towards the steel pipe 20 on the mounting seat 51. During the turning process of the cutting machine 52, the cutting machine 52 will drive the U-shaped frame 71 to slide downward in the first chute 62 through the vertical connecting rod 91, the horizontal connecting rod 92 and the collar 93. In the initial state, the two annular brushes 73 are located above the steel pipe 20. Due to the change in the curvature of the appearance of the steel pipe 20, during the downward sliding process of the U-shaped frame 71, the ejector rod 723 is pressed into the slideway 722. Under the elastic force of the second spring 724, the annular brush 73 on the ejector rod 723 always fits on the outer wall of the steel pipe 20. Then, drive the annular brush 73 to rotate at a high speed through the motor 74, and the rust removal or dirt removal of the surface of the cutting part of the steel pipe 20 can be realized, preventing the influence on the cutting effect and being beneficial to improving the cutting quality. Furthermore, when the cutting of the steel pipe 20 is completed, the two annular brushes 73 are located below the steel pipe 20. The electric telescopic column three 53 retracts and drives the cutting machine 52 to rotate and reset on the mounting seat 51. During the reset process of the cutting machine 52, the cutting machine 52 drives the U-shaped frame 71 to slide upward in the first chute 62 through the vertical connecting rod 91, the horizontal connecting rod 92 and the collar 93. During the sliding process, the debris at the cut is cleaned by the annular brush 73, eliminating the need to set up a cleaning mechanism in the subsequent process section and also eliminating the need for manual cleaning.

[0032] From the above description, it can be seen that before using the cutting machine 52 to cut the steel pipe 20, the surface of the cutting part of the steel pipe 20 will be rust-removed or dirt-removed first, and then the cutting machine 52 can immediately cut the cleaned part. There is no need to specifically set up a cleaning process in the previous section. Even if a cleaning process is specifically set up in the previous section, the surface of the steel pipe 20 will still be contaminated during the cutting process, resulting in repeated labor. However, in this invention, only the cutting part of the steel pipe 20 is cleaned, and after the cutting is completed, it is cleaned uniformly, without the phenomenon of repeated labor; moreover, during the reset process after cutting, the debris at the cut can be cleaned. This invention has a high degree of integration, a simple structure, and strong practicability.

[0033] In order to solve the technical problem that the oil stains and rust on the surface of the cutting part of the steel pipe 20 cannot be quickly cleaned only by the annular brush 73, as Figures 6-7 shown, the following preferred technical solutions are provided: The liquid spraying assembly 8 includes a piston cylinder 81 fixedly installed on the top surface of the fixed rod 721. A piston 82 is slidably installed inside the piston cylinder 81. An L-shaped connecting rod 83 is fixedly installed on the side wall of the piston 82. One end of the L-shaped connecting rod 83 away from the piston 82 is fixedly installed on the top surface of the ejector rod 723. A one-way liquid inlet valve 84 and a one-way liquid outlet valve 85 are respectively and fixedly connected and installed on the side wall of the piston cylinder 81. The one-way liquid inlet valve 84 is connected to the liquid storage tank 10 through a liquid pipe, and the one-way liquid outlet valve 85 is connected to the liquid spraying port 75 through a liquid pipe.

[0034] Specifically, when the ejector rod 723 retracts into the inside of the slideway 722, the ejector rod 723 will squeeze the solvent inside the piston cylinder 81 through the L-shaped connecting rod 83 and the piston 82. After being squeezed, the solvent will enter the inside of the liquid spraying port 75 through the one-way liquid outlet valve 85 and the liquid pipe, and finally be sprayed from the liquid spraying port 75 onto the annular brush 73. This enables the annular brush 73 to clean the surface of the cutting part of the steel pipe 20 while coating the solvent on the surface of the cutting part of the steel pipe 20 for cleaning the surface of the cutting part, which is beneficial to maintaining a good cutting effect and can reduce the probability of the cut section of the steel pipe 20 being contaminated, and thus will not affect the service life of the steel pipe 20; under the elastic force of the second spring 724, when the ejector rod 723 extends outward from the slideway 722, the ejector rod 723 will drive the piston 82 to move reversely in the inner cavity of the piston cylinder 81 through the L-shaped connecting rod 83, and draw the solvent contained in the liquid storage tank 10 into the piston cylinder 81 through the liquid pipe for the next use. By circulating the above operations, continuous and automatic liquid spraying operations can be achieved.

[0035] In order to solve the technical problem that the surface of the cutting part of the steel pipe 20 cannot be cleaned cleanly by the annular brush 73 after one cleaning, as Figures 9-12 shown, the following preferred technical solutions are provided: The vertical connecting rod 91 includes a vertical connecting rod main body 911 fixedly installed on the cutting machine 52. A third chute 912 is formed on the side wall of the vertical connecting rod main body 911. Installation grooves 913 are respectively formed on the opposite two side walls in the inner cavity of the third chute 912. A clamping block 914 is embedded and slidably installed in the inner cavity of the installation groove 913. The side wall of the clamping block 914 is elastically connected to the side wall of the inner cavity of the installation groove 913 through a third 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 clamping block 914 facing the electromagnet 916. The electromagnet 916 and the permanent magnet 917 are arranged in alignment. Circular grooves 918 are also respectively formed on the opposite two side walls in the inner cavity of the third chute 912.

[0036] The horizontal connecting rod 92 includes a horizontal connecting rod main body 921. The horizontal connecting rod main body 921 is fixedly connected to the collar 93. A clamping groove 922 is formed at one end of the horizontal connecting rod main body 921 close to the vertical connecting rod main body 911. A clamping connection can be formed between the clamping block 914 and the clamping groove 922. Rotating shafts 923 are respectively and fixedly installed on the outer walls of both sides of one end of the horizontal connecting rod main body 921 close to the vertical connecting rod main body 911. The rotating shafts 923 are rotatably arranged in the inner cavity of the circular groove 918.

[0037] Specifically, during the cutting process of the steel pipe 20, if the worker finds that there is a lot of rust or oil stain on the surface of the cutting part of the steel pipe 20, at this time, the electromagnet 916 is energized, so that the electromagnet 916 generates an attraction force on the permanent magnet 917, and the clamping block 914 is sucked into the inner cavity of the installation groove 913. At this time, the clamping connection between the clamping block 914 and the clamping groove 922 is released. Under the cooperative setting of the rotating shaft 923 and the circular groove 918, the collar 93 and the horizontal connecting rod 92 as a whole can rotate on the vertical connecting rod 91. At this time, the electric telescopic column 30 is started again to push the U-shaped frame 71 to reciprocate up and down in the first sliding groove 62. During the up and down reciprocating movement of the U-shaped frame 71, since the collar 93 and the horizontal connecting rod 92 as a whole can rotate on the vertical connecting rod 91, the horizontal connecting rod 92 and the collar 93 will not interfere with the operation of the U-shaped frame 71, and the surface of the cutting part of the steel pipe 20 can be cleaned multiple times by the annular brush 73 to ensure that the cutting part is smooth. When the cleaning is over, the electric telescopic column 30 resets, and the U-shaped frame 71 resets synchronously with the collar 93 and the horizontal connecting rod 92 as a whole. At this time, the electromagnet 916 is powered off. Under the elastic force of the third spring 915, the clamping block 914 is clamped into the clamping groove 922. At this time, the collar 93 and the horizontal connecting rod 92 as a whole cannot rotate on the vertical connecting rod 91, so that when the cutting machine 52 flips, the cleaning assembly 7 can still be driven by the vertical connecting rod 91, the horizontal connecting rod 92 and the collar 93.

[0038] Through the above settings, according to different amounts of rust residue and oil stain residue, the corresponding selection of the switch between single cleaning and multiple cleaning can achieve a better cleaning effect, which is beneficial to improving the cutting effect. Instead of realizing multiple cleaning by the reciprocating flipping of the cutting machine 52, it is beneficial to reduce the wear of the equipment.
