[0025] Two pressing grooves 22 are provided on the end surface of the docking snap ring 21, and a positioning block 23 is fixedly connected to the surface of the end of the docking snap ring 21 adjacent to the pressing groove 22. A convex hole 26 used in conjunction with the positioning block 23 is provided on the outer surface of the sleeve 20, and an arc-shaped channel 25 communicating with the convex hole 26 is provided on the inner wall of the sleeve 20, and a positioning slide groove 24 communicating with the arc-shaped channel 25 is provided on the end surface of the sleeve 20. The positioning slide groove 24 is slidably connected with the positioning block 23. When installing, the docking snap ring 21 is pressed so that the positioning block 23 on the docking snap ring 21 squeezes the pressing groove 22, and the positioning block 23 is aligned with the positioning block 23. The position of the positioning groove 24 is aligned, the positioning block 23 and the positioning groove 24 slide against each other and reach the end of the positioning groove 24. By toggling the pressure seat 15, the rotation drives the positioning block 23 on the docking clamp ring 21 to slide in the arc channel 25 through the positioning groove 24 and reach the inside of the convex hole 26. At this time, the outer wall of the docking clamp ring 21 is in contact with the inner wall of the sleeve 20, and the installation of the docking clamp ring 21 and the sleeve 20 is realized. The pressure seat 15 cooperates with the profile or pipe to be pressed together, so that the pressure seat 15 can adapt to the pressing of products of different shapes, thereby improving the application range of cutting products and making the range wider.

[0026] A buffer pressing mechanism is installed on the top surface of the fixed plate 14, and the buffer pressing mechanism includes a connecting seat 12 fixedly installed on the bottom surface of the lifting plate 4, and a telescopic rod 13 is fixedly installed on the bottom surface of the connecting seat 12 and the top surface of the fixed plate 14.

Two movable rods 17 that are movable with each other are hinged on the slider 19. When cutting the profile or pipe, the lifting plate 4 is pushed downward by the hydraulic cylinder, and the pressure seat 15 contacts the top surface of the profile or pipe. With the continued downward movement of the lifting plate 4, the two movable rods 17 respectively drive the corresponding slider 19 to slide on the slide rail 18, and the telescopic rod 13 is retracted and squeezed The spring 16 shortens the distance between the connecting seat 12 and the fixed plate 14, the pressing effect is better, and the quality of the profile or pipe when cutting is improved.

[0027] Two groups of parallel rubber pads 5 are installed on the top surface of the conveyor belt 2, and a support seat 6 for carrying rectangular profiles or round pipes is installed on the top surface of each rubber pad 5.

When sawing the profile or pipe, the support seat 6 of different shapes is replaced according to the shape of the product to be sawed. By pressing the two docking protrusions 10 at the bottom of the support seat 6, the corresponding elastic pressure plate 9 and the reset cavity groove are activated, so that the elastic pressure plate 9 enters the rubber pad 5. When the docking protrusion 10 on the elastic pressure plate 9 is engaged with the docking groove 8, the connection between the support seat 6 and the rubber pad 5 is realized, which is convenient for replacing support seats 6 of different shapes, adapting to the placement of rectangular profiles or round pipes, and used in conjunction with pressure seats 15 of different shapes.

The sawing wheel 7 enters the wheel groove 11 to avoid damage to the surface of the support seat 6 caused by the sawing wheel 7.

[0029] When the present invention is in use, the positioning block 23 and the positioning slot 24 slide against each other and reach the end of the positioning slot 24. By toggling the pressing seat 15, the positioning block 23 on the docking clamp ring 21 is rotated to slide through the positioning slot 24 in the arc-shaped channel 25 and reach the inside of the convex hole 26. At this time, the outer wall of the docking clamp ring 21 fits with the inner wall of the sleeve 20, so that the installation of the docking clamp ring 21 and the sleeve 20 is realized. The pressing seat 15 cooperates with the profile or pipe to be pressed, so that the pressing seat 15 can adapt to the pressing of products of different shapes, thereby improving the application range of cutting products.
