[0003] When a steel pipe is used in actual applications, it is sometimes necessary to drill multiple holes on its side, such as when installing multiple nozzles and faucets on a water pipe. However, the existing drilling device needs to fix the steel pipe first, drill the holes, move it, re-fix it, and then drill the holes again. As a result, the steel pipe needs to be fixed multiple times, which consumes a lot of time. Summary of the invention

[0035] like Figure 1-9 As shown, the steel pipe manufacturing device is described in detail:

[0036] A steel pipe manufacturing device comprises a main body frame 102, wherein two side plates 101 are symmetrically fixed to the lower end of the main body frame 102, a crossbeam 103 is fixed to the front and rear ends between the two side plates 101, two support plates 201 are connected through the two crossbeams 103, a middle tube 202 is fixed to the middle of the two support plates 201, and conical wheels 204 are rotatably connected to the opposite ends of the two middle tubes 202, a drill frame 401 is slidably penetrated through the middle of the main body frame 102, a drill seat 402 is provided at the lower end of the drill frame 401, an electric telescopic rod I 403 is installed between the drill frame 401 and the main body frame 102, main wheel frames 501 are slidably penetrated through the front and rear ends of the main body frame 102, driving wheels 502 are rotatably provided at the lower ends of the two main wheel frames 501, and electric telescopic rods II 503 are provided between the two main wheel frames 501 and the main body frame 102.

[0037] When drilling, first retract the electric telescopic rod I 403 and the two electric telescopic rods II 503; then insert the steel pipe to be drilled into the main frame 102 from front to back, and place it on the two conical wheels 204 on the two middle pipes 202, and support the steel pipe through the conical surfaces of the two conical wheels 204; thereby, the steel pipe will not roll left and right;

[0038] Then, the two electric telescopic rods II 503 are controlled to extend, and then the two driving wheels 502 are pressed on the steel pipe to be drilled. Since the two driving wheels 502 are respectively located at the front and rear ends of the two conical wheels 204, an inverted triangle fixing is formed to support the middle of the steel pipe and press the front and rear ends downward. At the same time, the steel pipe is in a horizontal state. At this time, when the two driving wheels 502 are not moving, the steel pipe cannot move forward and backward, thereby forming a fixed state of the steel pipe;

[0039] At this time, the drill seat 402 is started to drive the drill bit to rotate at high speed, and the electric telescopic rod I 403 is controlled to extend, so that the drill bit rotating at high speed on the drill frame 401 is lowered to drill the steel pipe; after the drilling is completed, the electric telescopic rod I 403 is controlled to retract to separate the drill bit from the steel pipe;

[0040] Then start the first motor installed on the main wheel frame 501 to drive the driving wheel 502 to rotate. Through the friction between the driving wheel 502 and the steel pipe, the steel pipe is kept in a horizontal state and moves axially. Then stop, fix the steel pipe again, control the electric telescopic rod I403 to extend again, drill again, and repeat the above steps to obtain a steel pipe with multiple circular holes.

[0041] In this process, it is only necessary to control the rotation of the driving wheel 502 to form the movement of the steel pipe, and when the driving wheel 502 stops, the steel pipe is fixed, thereby improving the fixing efficiency of the steel pipe and further improving the drilling efficiency of the steel pipe.

[0042] Further:

[0043] A bidirectional threaded rod 206 is rotatably passed through the middle of the two side plates 101 , and the two middle tubes 202 are respectively threadedly connected to the two ends of the bidirectional threaded rod 206 .

[0044] By rotating the bidirectional threaded rod 206, the two middle tubes 202 can be threadedly driven to move synchronously closer or farther, thereby adjusting the position between the two conical wheels 204 so that the device can adapt to the processing of steel tubes with different diameters.

[0045] At the same time, when the middle tube 202 moves, it drives the support plate 201 to move on the crossbeam 103 .

[0046] Further:

[0047] By locating the drill seat 402 just above the two conical wheels 204, it is prevented that the drilling part is deformed by the downward pressure of the drill bit, thereby affecting the drilling.

[0048] At the same time, by providing an elastic anti-skid rubber layer on the outside of the driving wheel 502, when the driving wheel 502 presses down the steel pipe, it can be deformed, and better friction is generated between the steel pipe, ensuring that the steel pipe is in a fixed state and transmitting the steel pipe.

[0049] like Figure 4-6 As shown:

[0050] The front and rear ends of the support plate 201 are sleeved with support arm tubes 301 , and each support arm tube 301 is provided with a support arm shaft 302 at the end away from the middle tube 202 , and a conical wheel 204 is rotated on each support arm shaft 302 .

[0051] By setting the support arm tube 301, the front and rear ends of the support plate 201 are extended, and the conical wheels 204 on the two opposite support arm shafts 302 at the same end can form auxiliary support for the front and rear ends of the steel pipe, so that the device can adapt to the support of a long steel pipe and avoid bending of the steel pipe when it is too long;

[0052] Moreover, by sleeve-mounting the arm tube 301 on the support plate 201 , the conical wheel 204 on the arm tube 301 can move laterally synchronously with the conical wheel 204 on the middle tube 202 .

[0053] Further:

[0054] A cylindrical seat 203 is coaxially slidably disposed inside each conical wheel 204 , and the plurality of cylindrical seats 203 are respectively rotated on the support arm shaft 302 or the support arm tube 301 .

[0055] An adjusting screw 205 is rotatably mounted on the conical wheel 204 , and the adjusting screw 205 is threadedly connected to the cylindrical seat 203 .

[0056] By rotating the adjusting screw 205, the adjusting screw 205 can be moved axially on the cylindrical seat 203, thereby driving the conical wheel 204 to move axially on the cylindrical seat 203, so that the width between the two conical wheels 204 arranged opposite to each other can be adjusted in cooperation with the bidirectional threaded rod 206, further making the device adaptable to steel pipes of different diameters;

[0057] Moreover, by protruding the cylindrical seat 203 from the conical wheel 204 on the inner side, the two oppositely arranged cylindrical seats 203 can adapt to the support of square or rectangular steel pipes, and cooperate with the left and right limit of the conical wheel 204, so that the device can also perform drilling processing on square or rectangular steel pipes.

[0058] Further:

[0059] By threading the support arm tube 301 with a tightening screw 303, the inner end of the tightening screw 303 presses against the corresponding support plate 201, so that the support arm tube 301 and the corresponding support plate 201 can be relatively fixed to ensure auxiliary support;

[0060] Moreover, by axially sliding the arm tube 301 on the support plate 201, the device can expand its adaptability to steel tubes of different lengths, and can adjust the different distances between the auxiliary support positions at the front and rear ends.

[0061] like Figure 1-9 As shown:

[0062] A manufacturing process using the steel pipe manufacturing device includes:

[0063] S1, placing the steel pipe to be drilled between the two conical wheels 204 on the two middle pipes 202, and supporting the steel pipe through the conical surfaces of the two conical wheels 204;

[0064] S2, control the two electric telescopic rods II 503 to extend, so that the two driving wheels 502 are pressed on the steel pipe to be drilled, and the steel pipe is in a horizontal fixed state;

[0065] S3, controlling the electric telescopic rod I 403 to extend, so that the drill frame 401 drives the high-speed rotating drill on the drill seat 402 to descend, and drills a hole in the steel pipe;

[0066] S4, after the drilling is completed, the electric telescopic rod I 403 is controlled to retract, so that the drill bit is separated from the steel pipe, the driving wheel 502 is driven to rotate, and then the steel pipe is kept in a horizontal state and moves axially, and then step S3 is repeated again to obtain a steel pipe with multiple circular holes.

[0067] Further:

[0068] A steel pipe has a plurality of circular holes on its side.
