DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The following are specific embodiments. For ease of understanding, the prior art is briefly introduced. Figure 3 As shown, the end of the pipe needs to be cut into several sharp teeth. If equipment is purchased for processing, but for small orders, purchasing different pipe cutting and processing equipment separately will increase the processing cost and the cost of subsequent maintenance. Therefore, the applicant designed a cutting equipment that can adapt to various pipe processing requirements.

[0021] For ease of description, Figure 1 The up and down directions are front and back, Figure 1 The left and right directions are left and right, and the direction perpendicular to the paper is up. Figure 1 and Figure 2 As shown, a new type of pipe cutting processing equipment includes a workbench 1, the workbench 1 is provided with a slide 2 that can move forward and backward, the slide 2 is detachably mounted with a knife seat 3, the knife seat 3 is provided with a cutting knife 4, one end of the slide 2 is provided with a driving cylinder 5 for driving the slide 2 to move forward and backward, the stroke of the driving cylinder 5 is not shorter than the front and rear length of the cutting knife 4, one side of the slide 2 is provided with a positioning frame 6, the positioning frame 6 is provided with a positioning seat 7 that can move up and down, a positioning shaft 8 that can be fitted on the relative inner side of the positioning seat 7 is rotatably mounted, the positioning shaft 8 is arranged above the knife seat 3, the axial direction of the positioning shaft 8 is arranged along the left and right direction of the knife seat 3, and the height difference between the axis of the positioning shaft 8 and the upper end face of the cutting knife 4 is not greater than the wall thickness of the pipe.

[0022] The upper end surface of the workbench 1 is provided with a plurality of front and rear slideways 9, the axial direction of which is arranged in the front-to-back direction. The arrangement of the plurality of slideways can be adjusted according to the actual installation position, facilitating the processing of a wider range of pipe materials. The lower portion of the slide 2 is provided with a slider 10, which is slidably mounted on the slideway. The combination of the slider 10 and the front and rear slideways 9 can limit the movement of the slide 2 to the front-to-back direction of the workbench 1.

[0023] A positioning threaded hole 11 is provided at a diagonal position on the upper portion of the slide 2. The tool holder 3 is provided with a positioning through-hole corresponding to the positioning threaded hole 11. The positioning through-hole is a stepped countersunk hole with a larger top and smaller bottom. A positioning bolt 12 is threaded through the positioning through-hole, which mates with the positioning threaded hole 11, thereby securing the tool holder 3 to the cutting blade 4. The positioning bolt 12 passes through the positioning through-hole and is threadedly connected to the positioning threaded hole 11, thereby securing the tool holder 3 to the slide 2. The positioning through-hole is a countersunk hole, which prevents the upper end of the positioning bolt 12 from affecting the flatness of the upper end surface of the tool holder 3.

[0024] The cutting blade 4 is arranged in a wavy shape when viewed from above and is embedded in the upper part of the blade holder 3. Because the pipe end needs to be processed into a sharp tooth shape, the wavy cutting blade 4 is used. As the cutting blade 4 moves and the pipe rotates, it can cut at different positions of the pipe end. The cutting blade 4 here can be used according to actual conditions. The blade holder 3 is made of wood and can be directly replaced according to the processing requirements to adapt to different processing requirements.

[0025] The positioning frame 6 includes a rectangular frame with relatively inner openings, and upper and lower slides 13 are provided on the relative inner walls of the rectangular frame. The positioning seat 7 is slidably installed on the upper and lower slides 13, and an adjusting screw rod 14 is rotatably installed in the upper and lower directions of the rectangular frame. The upper and lower parts of the rectangular frame are provided with screw rod seats, and the two ends of the adjusting screw rod 14 are respectively cooperated with the screw rod seats, that is, the rotation of the adjusting screw rod 14 is idling, and the positioning seat 7 is cooperated with the adjusting screw rod 14, and the upper end of the adjusting screw rod 14 extending out of the rectangular frame is provided with an adjusting handle 15. The upper part of the rectangular frame is provided with a limit seat 16 corresponding to the adjusting screw rod 14, and the limit seat 16 is provided with a limit bolt 17 for limiting the adjusting screw rod 14. The axial direction of the limit bolt 17 is arranged along the left and right directions of the knife seat 3, and the inner end of the limit bolt 17 cooperates with the adjusting screw rod 14, and the rectangular frame is convenient for processing. By turning the adjusting handle 15, the adjusting screw rod 14 is driven to rotate. Since the rotation of the adjusting screw rod 14 is idle, the upper and lower slides 13 can limit the positioning seat 7 to only move up and down on the adjusting screw rod 14, and the height of the positioning seat 7 is adjusted to achieve the height difference between the positioning shaft 8 and the cutting knife 4, thereby achieving adaptation to pipes of different outer diameters. When the position of the positioning seat 7 is adjusted, the limit bolt 17 is turned, and the axial direction of the limit bolt 17 is axially spirally rotated along the left and right directions of the knife seat 3. When it needs to be fixed, the inner end of the limit bolt 17 is against the adjusting screw rod 14, and the adjusting screw rod 14 cannot be rotated, thereby achieving the fixing of the height of the positioning seat 7.

[0026] When the utility model is in use, the pipe to be processed is firstly put on the positioning shaft 8, the operator selects the corresponding cutting knife 4 according to the actual pipe processing requirements, and then fixes the knife seat 3 provided with the cutting knife 4 on the slide 2, and then adjusts the upper and lower positions of the positioning seat 7 on the positioning frame 6 according to the outer diameter of the pipe, that is, adjusts the height difference between the positioning shaft 8 and the upper end surface of the cutting knife 4 to be not greater than the wall thickness of the pipe, to adapt to the processing of pipes with different outer diameters, starts the driving cylinder 5, and the piston rod of the driving cylinder 5 drives the slide 2 to move back and forth on the workbench 1, and the cutting knife 4 will abut the lower outer wall of the pipe so that the lower inner wall of the pipe abuts on the positioning shaft 8. The movement of the cutting knife 4 will drive the pipe to rotate. Since the lower inner wall of the pipe is abutted on the positioning shaft 8, the pipe and the positioning shaft 8 will rotate at the same time, thereby realizing the circumferential cutting processing of the pipe by the cutting knife 4, which can quickly process different pipes and reduce production costs.
