Description

Technical Field

[0001] This utility model relates to the field of pipe cutting machine technology, and in particular to a round pipe cutting machine. Background Technology

[0002] With economic development, the equipment needed in industrial production is becoming more and more widespread. Among them, cutting machines are one of the most widely used, especially in the production of round tubes, where they are frequently used to cut round tubes to the required length.

[0003] However, the current round tube cutting machine has a relatively simple structure. It usually cuts tubes by laser cutting or cutting wheels, which results in low cutting efficiency and cannot meet higher production requirements. Therefore, it is necessary to improve it. Utility Model Content

[0004] This utility model provides a round tube cutting machine that is easy to operate and use, has high cutting efficiency, and can improve processing quality to a certain extent, thus meeting higher production demands. It solves the technical problems of existing round tube cutting machines having a relatively simple structure, low processing efficiency, and inability to meet higher production demands.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: A round tube cutting machine includes a base, a plurality of bearings are mounted on the front side of the base, and a tube is inserted through the bearings. A support is provided on the rear side of the base, and a cutting arm is rotatably mounted on the support. A cutting blade for cutting the tube is provided on one side of the cutting arm, and a pressing component for driving the tube to rotate is provided below the cutting arm. Before processing, the tube is inserted into the bearing on the front side of the base from one side. During cutting, the cutting arm is manually pressed down. When pressed down, the pressing component below the cutting arm first contacts the tube and drives the tube to rotate. Subsequently, the cutting blade on one side of the cutting arm contacts the tube and cuts it, thus achieving fast and stable tube cutting.

[0006] Preferably, the pipe-pressing fitting includes a pipe-pressing arm rotatably mounted in the middle of the support. Several pulleys are rotatably mounted on the outer side of the pipe-pressing arm, and a circular belt is fitted around each pulley. The pipe-pressing arm can press down with the cutting arm. During the pressing process, the circular belt first contacts the pipe fitting. Driven by the pulleys, the circular belt drives the pipe fitting to rotate. Combined with the cutting blade on the cutting arm, this allows for fast and efficient cutting of the pipe fitting, and can improve processing quality and efficiency to a certain extent.

[0007] Preferably, the inner side of the pressing arm is equipped with a pressing motor for driving the pulley. The pressing motor is connected to the inner pulley, driving the circular belt to rotate. The left and right adjacent pulleys are connected by a coupling rod to ensure that the circular belts on the left and right sides rotate synchronously.

[0008] Preferably, a connecting plate is provided between the pipe pressing arms, and a pipe pressing spring is provided between the connecting plate and the cutting arm. During processing, the cutting arm is pressed down by manually holding the handle, and the pipe pressing arm moves downward accordingly. The circular band on the outside of the pipe pressing arm is pressed against the surface of the pipe under the action of the pipe pressing spring, and the pipe will rotate under the action of the circular band.

[0009] Preferably, the inner side of the cutting arm is equipped with a pipe-cutting motor connected to the cutting blade. The drive shaft of the pipe-cutting motor is fixedly connected to the cutting blade, and the pipe-cutting motor drives the cutting blade to rotate at high speed to cut the pipe.

[0010] Preferably, a gas spring is provided between the cutting arm and the base. The function of the gas spring is to facilitate the fixing of the cutting arm after it is raised, thus simplifying operation and use.

[0011] Preferably, the cutting arm is equipped with a handrail and control buttons on its front side. During processing, the handrail can be held to raise or lower the cutting arm, while the control buttons on the handrail can control the start and stop of the pipe cutting motor, making it convenient for the operator to control.

[0012] Preferably, a coupling is fixed on the machine base, and several bearings are installed on the coupling at intervals. The function of the coupling is to facilitate the fixing and positioning of the bearings.

[0013] Preferably, the machine base is provided with support seats on both sides for supporting the pipe fitting. Before processing, the pipe fitting is inserted from the support seat on one side, passes through the bearing on the coupling, and then exits from the other side, allowing the pipe fitting to rotate within the bearing.

[0014] Therefore, the round tube cutting machine of this utility model has the following advantages: it is easy to operate and use, the round belt can drive the pipe to rotate, and the cutting blade can effectively improve the processing efficiency and improve the processing quality to a certain extent, thus meeting higher production needs.

Detailed Implementation

[0020] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] Example:

[0022] like Figure 1 and 2 As shown in Figures 3 and 4, a round tube cutting machine includes a base 1. A coupling 2 is fixedly installed on the front side of the base 1. Several bearings 3 are installed at intervals on the coupling 2. Support seats 4 are symmetrically installed on the left and right sides of the base 1. Bearings 3 are also installed at intervals on the support seats 4. The tube passes through the support seats 4 and the bearings 3 on the coupling 2.

[0023] A bracket 5 is fixedly installed on the rear side of the base 1, and a cutting arm 6 is rotatably installed on the top of the bracket 5. A gas spring 7 is installed between the cutting arm 6 and the base 1.

[0024] A cutting blade 8 is rotatably mounted on the outer side of the cutting arm 6, and a pipe cutting motor 9 connected to the cutting blade 8 is mounted on the inner side of the cutting arm 6.

[0025] A handrail 10 and control buttons are fixedly installed on the front side of the cutting arm 6.

[0026] Below the cutting arm 6 is a pipe pressing device for driving the pipe to rotate. The pipe pressing device includes a pipe pressing arm 11 rotatably installed in the middle of the bracket 5. Four pulleys 12 are symmetrically installed on the left and right sides of the pipe pressing arm 11, and a round belt 13 is installed on the outer sleeve of the pulleys 12.

[0027] A pressure motor for driving the pulley 12 is installed on the inner side of the pressure arm 11. The pulleys 12 on the left and right sides are connected by a connecting rod to ensure synchronous rotation of the pulleys 12.

[0028] A connecting plate is fixedly installed between the left and right pressure arms 11, and a pressure spring 14 is installed between the connecting plate and the cutting arm 6.

[0029] Before processing, the pipe is inserted from the support seat 4 on one side, passes through the bearing 3 on the coupling 2, and then comes out from the other side. During cutting, the pipe cutting motor 9 and the pipe pressing motor are turned on by the control button. The cutting arm 6 is pressed down by manually holding the handle 10. The pipe pressing arm 11 moves down accordingly. The circular belt 13 on the outside of the pipe pressing arm 11 is pressed against the surface of the pipe under the action of the pipe pressing spring 14. Under the action of the circular belt 13, the pipe will rotate. As the cutting arm 6 is pressed down, the cutting blade 8 contacts the pipe and cuts it. With the rotation of the pipe, the pipe can be cut quickly.

[0030] After the cutting is completed, the cutting arm 6 is lifted, and under the action of the pipe pressing spring 14, the pipe pressing arm 11 will also be raised and disengaged from the pipe fitting.
