Description

Technical Field

[0001] The invention belongs to the technical field of cutting machine tools, in particular to a sewage steel pipe rapid cutting machine tool. Background Art

[0002] Sewage steel pipe is one of the indispensable pipe fittings in the drainage system of urban construction and housing projects. At present, in the processing and manufacturing process of sewage steel pipe, in order to facilitate the connection and installation of multiple sewage steel pipes, a cutting machine tool is usually used to cut a threaded connector on the outside of one end of the sewage steel pipe, and then a thread groove is cut on the inner wall of the other end of the sewage steel pipe, so that the sewage steel pipe can be threadedly connected with the thread groove inside another sewage steel pipe by using a threaded joint. This connection method of sewage steel pipe has higher sealing performance than that of butt connection with fastening bolts, and has a longer service life. In particular, sewage steel pipes used in housing construction projects are connected and installed using threads.

[0003] At present, when traditional cutting machine tools process threads on sewage steel pipes, they place the sewage steel pipe on a bracket, clamp the sewage steel pipe with a clamping and rotating device, and drive the sewage steel pipe to rotate at the same time. During the rotation of the sewage steel pipe, the cutting tool is controlled to approach the outer end of the sewage steel pipe. Then, during the rotation of the sewage steel pipe, the cutting tool is used to cut threads on the outer end of the sewage steel pipe to complete the rapid cutting of the sewage steel pipe.

[0004] There are still some problems in the actual application of the above scheme. During the rotation of the sewage steel pipe, after the cutting tool is controlled to approach one end of the outside of the sewage steel pipe, as the cutting tool continues to move, threads will be cut on the outside of the sewage steel pipe. However, in the process of using the cutting tool to cut threads on the sewage steel pipe, if the cut debris is not cleaned, the debris will be carried into the cutting place under the cutting action of the cutting tool. The cutting tool will squeeze the debris, causing friction between the debris and the threaded cut of the steel pipe, resulting in scratches and imprints on the newly cut thread groove, affecting the accuracy of the thread size.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Example:

[0036] like Figures 1 to 8As shown, a sewage pipe rapid cutting machine tool according to an embodiment of the present invention comprises a base 1, a slide groove 3 is provided on the upper end surface of the base 1, and grooves 31 are provided on both walls of the inner cavity of the slide groove 3, a fixing column 21 is fixedly connected to the inner cavity of the groove 3, an electric push rod 8 is slidably connected to the inner cavity of the slide groove 3, and a cutting and grinding component 9 is provided at the piston rod end of the electric push rod 8;

[0037] The cutting and grinding assembly 9 includes two first fixed blocks 26 fixedly connected to both sides of the piston rod end of the electric push rod 8, and L-shaped rotating blocks 901 are rotatably connected to the two ends of the first fixed block 26, and a rotating block 903 is rotatably connected to the inner cavity of the L-shaped rotating block 901, and multiple grinding blocks 904 are slidably connected to the outer part of the rotating block 903, and a cutting knife 902 is installed inside the piston rod end of the electric push rod 8;

[0038] A fixing seat 4 is fixedly connected to one side of the upper end surface of the base 1 , a slide rod 17 is slidably connected inside the upper end of the fixing seat 4 , an I-shaped support block 19 is fixedly connected to the upper end of the slide rod 17 , and the I-shaped support block 19 is used to place and support the sewage steel pipe 7 .

[0039] Specifically, in the prior art, during the rotation of the sewage steel pipe, after the cutting tool is controlled to approach one end of the outside of the sewage steel pipe, as the cutting tool continues to move, threads are cut on the outside of the sewage steel pipe. However, during the process of cutting threads on the sewage steel pipe using the cutting tool, if the cut debris is not cleaned, the debris will be carried into the cutting position under the cutting action of the cutting tool, and the cutting tool will squeeze the debris, causing friction between the debris and the threaded cut of the steel pipe, resulting in scratches and impressions on the newly cut thread groove, affecting the accuracy of the thread size.

[0040] The present invention places the sewage steel pipe 7 on the I-shaped support block 19, and moves one end of the sewage steel pipe 7 to the tail of one end of the slide 3, and uses an external clamping and rotating device to drive the sewage steel pipe 7 to rotate. During the rotation of the sewage steel pipe 7, the electric push rod 8 is started to drive the cutting knife 902 to move upward. During the upward movement of the cutting knife 902, the piston rod of the electric push rod 8 drives the first fixed block 26 to move upward, and drives the L-shaped rotating block 901 to move upward, so that the L-shaped rotating block 901 can be driven to rotate upward. 01 drives the rotating block 903 to open, and then makes the rotating block 903 fit with the outside of the sewage steel pipe 7 by means of the grinding block 904, and at the same time, the cutting knife 902 will fit with the surface of one end of the sewage steel pipe 7, and then drives the electric push rod 8 to move in the inner cavity of the slide groove 3, and during the movement of the electric push rod 8, it will drive the cutting knife 902 to move synchronously, and then use the cutting knife 902 to cut the sewage steel pipe 7 to reduce the diameter of the sewage steel pipe 7, and after the cutting is completed, the cutting knife 902 is driven by the electric push rod 8 to move upward, The cutting tool 902 is made to fit with the surface of the sewage steel pipe 7, and the electric push rod 8 is driven to move at a uniform speed in the inner cavity of the slide groove 3, so that the cutting tool 902 can cut the threads of the sewage steel pipe 7. In the process of cutting the threads on the surface of the sewage steel pipe 7 by the cutting tool 902, the grinding block 904 outside the rotating block 903 is used to grind the threads cut on the outside of the sewage steel pipe 7, and the grinding block 904 is used to clean the debris in the threads, so as to improve the quality of the threads cut on the outside of the sewage steel pipe 7. , avoiding the trouble of wasting a lot of time on grinding the threads of the sewage steel pipe 7 after cutting the threads, thereby solving the problem that when the existing sewage steel pipe rapid cutting machine uses a cutting knife to cut the threads of the sewage steel pipe, if the cut chips are not cleaned, these chips will be carried into the cutting place under the cutting action of the cutting knife, and the cutting knife will squeeze the chips, causing friction between the chips and the threaded incision of the steel pipe, resulting in scratches and impressions on the newly cut thread groove, affecting the accuracy of the thread size.

[0041] like Figure 1 , Figure 6 and Figure 7 As shown, a torsion spring mechanism is arranged inside the first fixed block 26, and the torsion spring mechanism includes a rotation groove 30 opened inside the first fixed block 26, and the inner cavity of the rotation groove 30 is rotatably connected to a rotation shaft 27, and both ends of the rotation shaft 27 pass through the first fixed block 26 and are fixedly connected to the L-shaped rotation block 901.

[0042] like Figure 1 , Figure 6 and Figure 7 As shown, the rotating shaft 27 is located outside the inner cavity of the rotating groove 30 and is fixedly connected to a fixed plate 28 . Both end surfaces of the fixed plate 28 are fixedly connected to torsion springs 29 . The end of the torsion spring 29 away from the fixed plate 28 is fixedly connected to the inner wall of the rotating groove 30 .

[0043] Specifically, when cutting the sewage steel pipe 7, the cutting knife 902 is driven to move upward by the electric push rod 8, and the piston rod of the electric push rod 8 drives the first fixed block 26 to move upward, and at the same time, the first fixed block 26 drives the L-shaped rotating block 901 to move upward, and during the upward movement of the L-shaped rotating block 901, it drives the rotating block 903 to move upward and fit with the surface of the sewage steel pipe 7, and as the first fixed block 26 continues to move upward, the L-shaped rotating block 901 drives the rotating block 903 to flip along with the surface diameter of the sewage steel pipe 7, and when the L-shaped rotating block 901 rotates During the process, the rotating shaft 27 will be driven to rotate, and the rotating shaft 27 will drive the fixed disk 28 to rotate, and the fixed disk 28 will drive the torsion spring 29 to twist, and then the rotational force of the torsion spring 29 will be used to twist the fixed disk 28, and the fixed disk 28 will drive the rotating shaft 27 to rotate, and the rotating shaft 27 will drive the L-shaped rotating block 901 to rotate, thereby ensuring that the L-shaped rotating block 901 drives the rotating block 903 to always fit with the surface of the sewage steel pipe 7, and then the rotating block 903 is used to grind the threads cut out of the sewage steel pipe 7 using the grinding block 904, thereby improving the practicability of the cutting machine tool.

[0044] like Figure 1 , Figure 6 and Figure 7 As shown, a plurality of T-shaped slots 905 are evenly arranged on the outside of the rotating block 903 , and a micro spring 906 is fixedly connected to the bottom of the inner cavity of the plurality of T-shaped slots 905 , and one end of the micro spring 906 is fixedly connected to the grinding block 904 .

[0045] Specifically, when the rotating block 903 uses the grinding block 904 to grind the threads cut by the sewage steel pipe 7, the micro spring 906 in the inner cavity of the T-shaped slide groove 905 is used to bounce the grinding block 904, and the grinding block 904 is inserted into the thread groove cut by the sewage steel pipe 7, and then the grinding block 904 can be used to grind the inner wall of the thread groove cut by the sewage steel pipe 7, and the thread protrusion cut by the sewage steel pipe 7 will squeeze the grinding block 904, and the grinding block 904 will slide into the inner cavity of the T-shaped slide groove 905, squeezing the T-shaped slide groove 905 at the same time. The micro spring 906 in the inner cavity is then used to push the grinding block 904, so that the grinding block 904 fits tightly with the threaded protrusions cut out of the sewage steel pipe 7, and then the grinding block 904 grinds the surface of the threaded protrusions cut out of the sewage steel pipe 7, thereby solving the problem that in the process of using a cutting knife to cut threads on the sewage steel pipe in the existing sewage steel pipe rapid cutting machine, it is inconvenient to grind the threads cut out of the sewage steel pipe, resulting in the surface of the threads cut out of the sewage steel pipe being not smooth enough, affecting the quality of the finished sewage steel pipe.

[0046] like Figure 1 , Figure 4 and Figure 5As shown, the inner cavity of the groove 31 is rotatably connected to a threaded rod 22, a servo motor 2 is fixedly connected to one side of the base 1, and the output shaft end of the servo motor 2 is fixedly connected to the threaded rod 22, the outer thread of the threaded rod 22 is threadedly connected to a slider 23, the outer side of the fixed column 21 is slidably connected to the slider 23, and the slider 23 is fixedly connected to the electric push rod 8.

[0047] Specifically, after placing the sewage steel pipe 7 on the I-shaped support block 19, the external clamping and rotating equipment is used to drive the sewage steel pipe 7 to rotate. During the rotation of the sewage steel pipe 7, the electric push rod 8 is started to drive the cutting tool 902 to move upward and fit the surface of one end of the sewage steel pipe 7. Then the servo motor 2 is started to drive the threaded rod 22 to rotate, and the threaded transmission slider 23 of the threaded rod 22 is moved along one end of the inner cavity of the groove 31, and the electric push rod 8 is driven to move at the same time. At the same time, the electric push rod 8 drives the slider 23 to move outside the fixed column 21, and the electric push rod 8 will drive the cutting tool 902 to move synchronously during the movement, and then the cutting tool 902 is used to cut threads on the sewage steel pipe 7, and the thread of the threaded rod 22 is used to drive the electric push rod 8 to move at a uniform speed, thereby improving the accuracy of cutting threads on the sewage steel pipe 7.

[0048] Example:

[0049] like Figure 1 and Figure 3 As shown, the inner cavity of the I-shaped support block 19 is rotatably connected to two rollers 20, and the outer parts of the two rollers 20 are both slidably connected to a plurality of balls 32.

[0050] Specifically, when the sewage steel pipe 7 is placed on the I-shaped support block 19, two rollers 20 in the inner cavity of the I-shaped support block 19 are used to lift the sewage steel pipe 7, and a plurality of balls 32 slide evenly on the outside of the rollers 20, so as to facilitate the movement of the sewage steel pipe 7 on the I-shaped support block 19, thereby preventing the problem that when the sewage steel pipe 7 needs to be adjusted after being placed on the I-shaped support block 19, it is difficult to push the sewage steel pipe 7 to adjust its position because the I-shaped support block 19 does not have a sliding component.

[0051] like Figure 1 , Figure 3 and Figure 5 As shown, second fixing blocks 33 are fixedly connected on both sides of the fixing seat 4, a torsion spring mechanism is arranged in the inner cavity of the second fixing block 33, and clamping rods 5 are fixedly connected at both ends of the torsion spring mechanism, one end of the clamping rod 5 is rotatably connected to three rubber clamping rollers 6, and a plurality of balls 32 are evenly slidably connected to the outside of the three rubber clamping rollers 6.

[0052] Specifically, after the sewage steel pipe 7 is placed on the I-shaped support block 19, the clamping rod 5 is rotated closer to each other by utilizing the torsion spring mechanism, and at the same time, the clamping rod 5 drives the rubber clamping roller 6 to rotate synchronously, so that the rubber clamping roller 6 is fitted with the outer part of the upper end of the sewage steel pipe 7, so that the rubber clamping roller 6 presses the sewage steel pipe 7, and the sewage steel pipe 7 is fixed between the I-shaped support block 19 and the rubber clamping roller 6, so as to ensure the stability of the sewage steel pipe 7. A plurality of balls 32 are evenly slid inside the outer part of the rubber clamping roller 6, so that during the process of clamping and fixing the sewage steel pipe 7, the sewage steel pipe 7 can be conveniently adjusted to the cutting position, thereby improving the convenience and practicality of the cutting machine.

[0053] like Figures 1 to 4 As shown, a receiving groove 18 is formed at the upper end of the fixing seat 4 , a support spring 16 is fixedly connected to the bottom of the inner cavity of the receiving groove 18 , and one end of the support spring 16 is fixedly connected to the sliding rod 17 .

[0054] like Figures 1 to 4 As shown, a fixing cylinder 15 is fixedly connected to the bottom of the inner cavity of the receiving groove 18, and a T-shaped sliding column 14 is slidably connected to the inner cavity of the fixing cylinder 15. A rubber pad is arranged on the outer side of the lower end of the T-shaped sliding column 14, and fits with the inner wall of the fixing cylinder 15 to seal the inner cavity of the fixing cylinder 15.

[0055] like Figure 3 to Figure 4 As shown, an air guide cavity 13 is opened at the bottom of the inner cavity of the fixed cylinder 15, and the air guide cavity 13 is located at one end of the inner wall of the slide groove 3 and is fixedly connected to a folding conduit 12, and one end of the folding conduit 12 is fixedly connected to a cleaning nozzle 11, a fixed sleeve 10 is installed on the outside of the cleaning nozzle 11, and the fixed sleeve 10 is fixedly connected to the electric push rod 8, and two one-way valves are arranged in the inner cavity of the air guide cavity 13, and one one-way valve is used to control the air intake, and the other one-way valve is used to control the exhaust.

[0056] Specifically, in the process of cutting threads on the sewage steel pipe 7, the sewage steel pipe 7 is pressed by the rubber clamping roller 6 to fix the sewage steel pipe 7 between the I-shaped support block 19 and the rubber clamping roller 6. In the process of the rubber clamping roller 6 pressing the sewage steel pipe 7 to move downward, the sewage steel pipe 7 will press down to push the I-shaped support block 19 to move downward, and the I-shaped support block 19 pushes the slide bar 17 to move downward. At the same time, the slide bar 17 squeezes the support spring 16 to push the T-shaped slide column 14 to move downward, and the T-shaped slide column 14 slides downward in the inner cavity of the fixed cylinder 15, and then squeezes the air in the inner cavity of the fixed cylinder 15 into the air guide cavity 13. At the same time, the air squeezes to form a pressure to open the one-way valve and enter the inner cavity of the folding guide tube 12, and then enters the inner cavity of the cleaning nozzle 11 through the folding guide tube 12, and at the same time, passes through the cleaning nozzle 11. Blow and clean the debris generated by the cutting knife 902 to prevent the debris from sticking and accumulating on the cutting knife 902, and at the same time prevent the debris from sticking in the threads cut by the sewage steel pipe 7, causing the debris to be carried into the cutting area under the cutting action of the cutting knife, and the cutting knife will squeeze the debris, causing the debris to rub against the threaded cut of the steel pipe, affecting the accuracy of the thread size, thereby solving the problem that when the existing sewage steel pipe rapid cutting machine uses the cutting knife to cut the threads of the sewage steel pipe, if the cut debris is not cleaned, the debris will be carried into the cutting area under the cutting action of the cutting knife, and the cutting knife will squeeze the debris, causing the debris to rub against the threaded cut of the steel pipe, causing scratches and imprints on the newly cut thread groove, affecting the accuracy of the thread size.

[0057] The working principle is as follows: the sewage steel pipe 7 is placed on the I-shaped support block 19, and one end of the sewage steel pipe 7 is moved to the tail of one end of the slide 3, and the external clamping and rotating device is used to drive the sewage steel pipe 7 to rotate. During the rotation of the sewage steel pipe 7, the electric push rod 8 is started to drive the cutting knife 902 to move upward. During the upward movement of the cutting knife 902, the piston rod of the electric push rod 8 will drive the first fixed block 26 to move upward, and at the same time drive the L-shaped rotating block 901 to move upward, so that the L-shaped rotating block 901 can drive the rotating block 903 to open, and then the rotating block 903 is made to fit the outside of the sewage steel pipe 7 with the grinding block 904, and at the same time, the cutting knife 902 will fit the surface of one end of the sewage steel pipe 7, and then the electric push rod 8 is driven to move in the inner cavity of the slide 3. During the movement of the electric push rod 8, the cutting knife 9 02 moves synchronously, and then uses the cutting tool 902 to cut the sewage steel pipe 7 to reduce the diameter of the sewage steel pipe 7. After the cutting is completed, the cutting tool 902 is driven to move upward by the electric push rod 8, and the cutting tool 902 is fitted with the surface of the sewage steel pipe 7. At the same time, the electric push rod 8 is driven to move at a uniform speed in the inner cavity of the slide groove 3, so that the cutting tool 902 can cut the thread of the sewage steel pipe 7. In the process of using the cutting tool 902 to cut the thread on the surface of the sewage steel pipe 7, the grinding block 904 outside the rotating block 903 is used to grind the thread cut on the outside of the sewage steel pipe 7. At the same time, the grinding block 904 is used to clean the debris in the thread, so as to improve the quality of the thread cut on the outside of the sewage steel pipe 7 and avoid the trouble of wasting a lot of time on grinding the thread after the sewage steel pipe 7 is cut.

[0058] In the process of cutting the threads of the sewage steel pipe 7, the sewage steel pipe 7 is pressed by the rubber clamping roller 6, so that the sewage steel pipe 7 is fixed between the I-shaped support block 19 and the rubber clamping roller 6. In the process of the rubber clamping roller 6 pressing the sewage steel pipe 7 to move downward, the sewage steel pipe 7 will press down to push the I-shaped support block 19 to move downward, and the I-shaped support block 19 pushes the slide bar 17 to move downward. At the same time, the slide bar 17 squeezes the support spring 16 to push the T-shaped slide column 14 to move downward, and the T-shaped slide column 14 slides downward in the inner cavity of the fixed cylinder 15, and then squeezes the air in the inner cavity of the fixed cylinder 15 to be discharged into the air guide cavity 13, and at the same time, the air squeezes to form pressure to open the one-way valve and enter the inner cavity of the folding conduit 12, and then enters the inner cavity of the cleaning nozzle 11 through the folding conduit 12, and at the same time, the debris generated by the cutting of the cutting knife 902 is blown and cleaned through the cleaning nozzle 11 to prevent the debris from sticking and accumulating on the cutting knife 902, and at the same time prevent the debris from sticking to the threads cut by the sewage steel pipe 7, causing the debris to be carried into the cutting place under the cutting action of the cutting knife, and the cutting knife will squeeze the debris, causing the debris to rub against the threaded incision of the steel pipe, affecting the accuracy of the thread size.
