Description

Technical Field

[0001] This utility model relates to the field of cutting devices, and more specifically, to a steel pipe cutting device. Background Technology

[0002] Steel pipes have a hollow cross-section, and their length is much greater than their diameter or circumference. After the steel pipes are produced, they need to be cut into pipes of the same length. The existing steel pipe cutting is mostly done by a person holding a cutting knife and moving it along the side wall of the steel pipe to cut it. This can easily lead to different lengths of steel pipes being cut and low cutting efficiency. To address this, we have proposed a steel pipe cutting device. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a steel pipe cutting device that uses a clamping block to push the steel pipe to move, thereby facilitating the movement of the steel pipe by the same length, which in turn facilitates the cutting blade to cut the steel pipe into the same length, improving cutting efficiency. At the same time, it is convenient to adjust the height of the cutting blade, thus making it easy for the cutting blade to adapt to the diameter of the steel pipe.

[0005] 2. Technical Solution

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A steel pipe cutting device includes a pushing tube, two symmetrically arranged mounting plates mounted on the side wall of the pushing tube, and mounting blocks mounted on the side walls of both mounting plates. A first electric push rod is mounted on the upper end of the mounting blocks and the upper end of the mounting plates. A sliding plate is mounted on the output end of the first electric push rod. A second electric push rod is mounted on the upper end of the sliding plate. An auxiliary block is mounted on the output end of the second electric push rod. A clamping block is mounted on the side wall of the auxiliary block. A support frame is mounted on the upper end of the pushing tube. A fixing plate is mounted on the side wall of the support frame. A third electric push rod is mounted on the side wall of the fixing plate. A mounting box is mounted on the lower end of the third electric push rod. A servo motor is mounted on the inner wall of the mounting box. A drive shaft is mounted on the output end of the servo motor via a coupling. A cutting blade is mounted on the side wall of the drive shaft.

[0008] Furthermore, the side wall of the pushing tube is provided with an auxiliary groove, and the height of the side wall of the clamping block is adapted to the height of the inner wall of the auxiliary groove, so that the clamping block can pass through the auxiliary groove to clamp the steel pipe.

[0009] Furthermore, the lower end of the inner wall of the push tube is set in an arc shape, and the axis of the cutting blade and the axis of the push tube are on the same vertical horizontal plane, which makes it convenient for the clamping block to clamp the steel pipe, thereby making it easier to keep the steel pipe stable.

[0010] Furthermore, the side wall of the mounting box is connected to a side cover by bolts and threads. Both the side cover and the side wall of the mounting box have threaded holes. The side wall of the bolt and the inner wall of the threaded hole are provided with matching threads. The side wall of the mounting box is provided with an exhaust groove, which facilitates opening the inner cavity of the mounting box, thereby facilitating the maintenance of the servo motor and facilitating heat dissipation of the mounting box through the exhaust groove.

[0011] Furthermore, the push tube includes two inclined plates and an arc-shaped plate. The two inclined plates are respectively installed on the upper end of the arc-shaped plate to facilitate the pipe falling into the arc-shaped plate, thereby facilitating the pipe to fall into the lower end of the inner wall of the push tube.

[0023] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 A steel pipe cutting device includes a push tube 1, two symmetrically arranged mounting plates 2 installed on the side wall of the push tube 1, mounting blocks 3 installed on the side wall of each mounting plate 2, a first electric push rod 4 installed on the upper end of the mounting block 3 and the upper end of the mounting plate 2, a sliding plate 5 installed on the output end of the first electric push rod 4, a second electric push rod 6 installed on the upper end of the sliding plate 5, an auxiliary block 7 installed on the output end of the second electric push rod 6, a clamping block 8 installed on the side wall of the auxiliary block 7, a support frame 9 installed on the upper end of the push tube 1, a fixing plate 10 installed on the side wall of the support frame 9, a third electric push rod 11 installed on the side wall of the fixing plate 10, a mounting box 12 installed on the lower end of the third electric push rod 11, a servo motor 13 installed on the inner wall of the mounting box 12, a transmission shaft 14 installed on the output end of the servo motor 13 through a coupling, and a cutting blade 15 installed on the side wall of the transmission shaft 14.

[0024] The side wall of the push tube 1 is provided with an auxiliary groove, and the height of the side wall of the clamping block 8 is adapted to the height of the inner wall of the auxiliary groove, so that the clamping block 8 can pass through the auxiliary groove to clamp the steel pipe.

[0025] The lower end of the inner wall of the push tube 1 is set to be arc-shaped, and the axis of the cutting blade 15 is on the same vertical horizontal plane as the axis of the push tube 1, which makes it convenient for the clamping block 8 to clamp the steel pipe, thereby making it easier to keep the steel pipe stable.

[0026] The side wall of the mounting box 12 is connected to a side cover by bolts and threads. Both the side cover and the side wall of the mounting box 12 have threaded holes. The side wall of the bolt and the inner wall of the threaded hole are provided with matching threads. The side wall of the mounting box 12 is provided with an exhaust groove, which makes it easy to open the inner cavity of the mounting box 12, thereby facilitating the maintenance of the servo motor 13 and facilitating the heat dissipation of the mounting box 12 through the exhaust groove.

[0027] The push tube 1 includes two inclined plates and an arc plate. The two inclined plates are respectively installed on the upper end of the arc plate to facilitate the pipe falling into the arc plate, thereby facilitating the pipe to fall into the lower end of the inner wall of the push tube 1.

[0028] In use, a technician in the field places the pipe on the inner wall of the push tube 1. Then, the second electric push rod 6 and the first electric push rod 4 are activated. The second electric push rod 6 pushes the clamping block 8 to the steel pipe through the auxiliary block 7, and the first electric push rod 4 pushes the second electric push rod 6 to move, thus facilitating the movement of the second electric push rod 6 towards the push tube 1, and thus facilitating the clamping block 8 to clamp the pipe. Then, the third electric push rod 11 is activated, which pushes the mounting box 12 to move and activates the servo motor 13. The servo motor 13 drives the cutting blade 15 to rotate through the transmission shaft 14, thus facilitating the cutting blade 15 to cut the steel pipe. The above actions are repeated to facilitate the cutting of the steel pipe. This utility model uses the clamping block 8 to push the steel pipe to move, thus facilitating the movement of the steel pipe by the same length, thus facilitating the cutting blade 15 to cut the steel pipe to the same length, improving cutting efficiency. At the same time, it is convenient to adjust the height of the cutting blade 15, thus facilitating the cutting blade 15 to adapt to the diameter of the steel pipe.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
