Detailed ways

The present invention will be described in further detail below with reference to the accompanying drawings.

As shown in Figures 1-6, the automatic pipe cutting machine of this embodiment includes a frame 11, a cutting mechanism 13, a traction mechanism 14, a stretching mechanism 15, and a positioning mechanism 17, and the stretching mechanism 15 and the positioning mechanism 17 are all installed on the frame 11, the stretching mechanism 15 is slidably mounted on the frame 11 and is between the cutting mechanism 13 and the positioning mechanism 17; 15 is driven to extend toward the positioning mechanism 17. When the stretching mechanism 15 or the pipe to be cut touches the positioning mechanism 17, the stretching mechanism 15 stops sliding and the cutting mechanism 13 will be cut. Pipe cut off. The structure of each part will be described in detail below.

The frame 11 is a metal structure with strong structural strength and deformation resistance, and can effectively bear the pressure and impact of the automatic pipe cutting machine during work.

One end of the frame 11 is equipped with a power distribution box 12, and a plate is fixedly installed on the top of the power distribution box 12, and the plate is also fixedly connected with the frame 11. The platen is horizontal, and a traction mechanism 14, a guiding mechanism and a cutting mechanism 13 are installed on the platen.

Traction mechanism 14 comprises a traction wheel, and the auxiliary wheel that is oppositely installed with traction wheel, traction wheel is driven and rotated by a drive mechanism, and drive mechanism is installed in the distribution box 12, and this drive mechanism can adopt prior art, as by motor Wait for the drive. The auxiliary wheel is movably assembled on a mounting part, and the mounting part is movably connected with the support, and two springs are pressed between the two. The support is fixed on the table, and the mounting part can move relative to the support. Therefore, when the pipe to be cut passes between the traction wheel and the auxiliary wheel, the pipe to be cut is pressed against the traction wheel by the elastic force of the two springs, so that the pipe to be cut is pressed against the traction wheel. The cutting pipe does not deviate during the movement.

A guide mechanism is also fixed on the platen. The guide mechanism is a guide pipe. The direction of the pipe hole of the guide pipe is on a straight line with the gap between the traction wheel and the auxiliary wheel, so that the pipe to be cut can be moved from the traction wheel to the auxiliary wheel. After the wheel comes out, it extends to the direction of the positioning mechanism through the guide pipe. The guide pipe can limit the motion track of the pipe to be cut, so that the pipe to be cut moves along a fixed track.

The cutting mechanism 13 of the present embodiment adopts an existing cutting machine, which includes parts such as a motor, a belt, a rotating shaft and a cutting piece, and the cutting piece can move up and down. Since the cutting mechanism adopts the prior art, it will not be described in detail. The cutting mechanism 13 is installed on the table, the pipe to be cut is directly under the cutting piece, and is perpendicular to the pipe to be cut.

A guide rail 16 is installed on the frame 11, and the length direction of the guide rail 16 is consistent with the moving direction of the pipe to be cut and is on the same straight line. One end of the guide rail 16 is fixed on the platform, and this end corresponds to the guide pipe.

A positioning mechanism 17 is installed on the guide rail 16 , and the positioning mechanism 17 is detachably assembled on the guide rail 16 . By adjusting the distance between the positioning mechanism 17 and the cutting piece of the cutting mechanism 13, the length of the cut pipe can be adapted, and the length can be determined according to actual needs.

The positioning mechanism 17 can adopt a photoelectric switch, a laser range finder, etc. When the stretching mechanism 15 slides and touches it, the positioning mechanism 17 can obtain a corresponding trigger signal and send it to the PLC programmable controller. After the PLC programmable controller receives the feedback signal, it controls the traction mechanism 14 and the stretching mechanism 15 to stop, and the cutting piece of the cutting mechanism 13 swings downward to cut off the pipe to be cut.

PLC programmable controller can adopt prior art, and it is installed in the distribution box 12, and it is used for carrying out general control to cutting mechanism 13, traction mechanism 14, stretching mechanism 15 and positioning mechanism 17 etc.

A sliding stretching mechanism 15 is assembled on the guide rail 16, and the stretching mechanism 15 includes a stretching cylinder, which is between the positioning mechanism 17 and the cutting mechanism 13, and can slide between the positioning mechanism 17 and the cutting mechanism 13. When the pipe to be cut is under the stretching cylinder, the stretching cylinder presses the pipe to be cut downwards and drives the pipe to be cut to translate in the direction of the positioning mechanism 17. When the positioning switch 17 is touched, the cutting mechanism 13 will move the pipe to be cut Cutting off, after cutting off the pipe fittings, the stretching cylinder releases the pipe fittings, and the pipe fittings automatically fall into the connecting groove at the lower part of the frame.

A slant plate is also arranged between the takeover groove at the bottom of the frame 11 and the guide rail 16, so that the cut pipe fittings can smoothly fall into the takeover groove.

The cutting mechanism 13 and the stretching mechanism 15 reset automatically after completing a cutting action.

In this embodiment, the control of the entire cutting process is completed by setting the parameters of the PLC programmable controller, and the automatic cutting of the pipe to be cut is realized. For example, the pressing speed of the cutting mechanism and/or the rotation speed of the cutting mechanism can be set to control the quality of the pipe obtained in a single cut; the cutting can also be controlled by setting the number of starts and stops of the cutting mechanism, traction mechanism and stretching mechanism. The number of times to obtain different numbers of cut pipes.

On the basis of ensuring sufficient supply of pipe fittings to be cut, the automatic pipe cutting machine in this embodiment can reach the non-stop working state after being turned on, and a plurality of machines are controlled by fewer equipment operators, further saving human resources and improving production efficiency. It also avoids the possibility of the operator suffering from work-related injuries.

As shown in Figure 4, the specific process of the automatic pipe cutting machine to complete a working cycle is as follows:

When the pipe to be cut is pulled by the traction mechanism 14 and reaches under the stretching mechanism 15, the stretching mechanism 15 automatically presses down and holds the pipe to be cut. After the pipe to be cut is fixed, as shown by the arrow in Figure 4, the stretching The mechanism 15 moves along the guide rail 16 toward the positioning mechanism 17, and drags the pipe to be cut to the positioning mechanism 17; when the stretching mechanism 15 or the pipe to be cut touches the positioning mechanism 17, the positioning mechanism 17 sends a trigger signal to the control device, the controller controls the traction mechanism 14 and the stretching mechanism 15 to stop working, and simultaneously controls the cutting mechanism 13 to press down on the pipe to be cut to cut. After the cutting is completed, the cutting mechanism 13 swings upwards to reset, and the stretching mechanism 15 moves and resets along the guide rail 16; Carry out traction and enter the next working cycle. Repeat the previous action process. Working repeatedly in this way, the automatic cutting of the pipe fittings to be cut is automatically realized. Equipment operators only need to pay attention to the supply of pipe fittings to be cut, which greatly saves the required human resources, achieves the purpose of reducing production costs, and avoids the occurrence of safety accidents in the production process. The cut pipes fall naturally, and there is no need for equipment operators to collect the cut pipes.

This embodiment uses mechatronics to control the steps of feeding, fixing and cutting in the pipe cutting process, which improves the cutting accuracy and safety; realizes the automatic cutting of pipes, improves work efficiency and reduces work costs.
