Description

Technical Field

[0001] This utility model relates to the field of PVC pipe processing technology, specifically to a PVC pipe processing ring cutting device. Background Technology

[0002] Cutting is a crucial step in the production and processing of PVC pipes. Traditional cutting methods often suffer from problems such as low cutting precision, low efficiency, and complex operation. Therefore, it is particularly important to develop a device that can cut PVC pipes efficiently and accurately.

[0003] Referring to the PVC pipe circumferential cutting equipment disclosed in CN221249012U, it includes: a first frame assembly and a second frame assembly capable of being folded into a circle; the first frame assembly includes a first outer frame, and a second outer frame is mounted on the left side of the first outer frame via a pin; the second frame assembly includes a first movable frame and a second movable frame connected to each other via pins; a third movable frame is connected on the left side of the first movable frame via a pin, and the other end of the third movable frame is connected to the other end of the second outer frame via a pin; the outer walls of the first outer frame, the first movable frame, and the second movable frame are respectively equipped with a plurality of outer shells. This PVC pipe circumferential cutting equipment, in practical use, can perform circumferential cutting of PVC pipes, is easy to use, and can adjust the depth of the cutter according to different pipe wall requirements, thereby completely penetrating the pipe wall. However, as can be seen from the above, although this circumferential cutting equipment can be well applied, it is usually not convenient to limit the cut end of the pipe, making it prone to vibration during pipe cutting, thus affecting the cutting accuracy of the circumferential cutting equipment and often troubling users. Utility Model Content

[0004] The purpose of this utility model is to provide a PVC pipe processing ring cutting equipment to solve the problem mentioned in the background art that although the ring cutting equipment can be used well, it is usually not convenient to limit the cut end of the pipe, which makes the pipe cutting process prone to vibration, thus affecting the cutting accuracy of the ring cutting equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PVC pipe processing and ring cutting equipment, including a cabinet, an electrical control box on one side of the top of the cabinet, and a chassis on the other side of the top of the cabinet. A positioning plate is located on the top of the cabinet inside the chassis. A pipe body is movably installed inside the positioning plate, with one end of the pipe body extending to the outside of the chassis. A limit roller is rotatably mounted on the outer wall of the positioning plate below the pipe body via a bracket. First cylinders are rotatably mounted on the outer walls of the positioning plates on both sides of the pipe body. A drive arm is rotatably mounted on the bottom end of each first cylinder. The drive arm is positioned at a distance from... The inner wall at one end of the first cylinder is rotatably connected to the outer wall of the positioning plate. A cutter is installed on the outer wall of the drive arm. A second cylinder is installed on the outer wall of the positioning plate between the pipe body and the first cylinder. A limit roller is installed at the bottom of the second cylinder. A screw drive mechanism is provided inside the cabinet at the chassis position. A third motor is installed on the outer wall of one side of the screw drive mechanism. A nut seat is installed on one side of the bottom end of the screw drive mechanism. A component holder is provided at the top of the nut seat. The top of the component holder extends into the interior of the chassis and is equipped with a first motor. A three-jaw chuck is installed at one end of the first motor.

[0006] Preferably, a base is provided at the top of the cabinet between the chassis and the electrical control box, and a bidirectional lead screw is rotatably installed at the top of the base to facilitate the placement of the threaded cylinder.

[0007] Preferably, threaded cylinders are threadedly installed on the outer walls of both sides of the bidirectional lead screw. The top end of the threaded cylinder is provided with a V-shaped chuck, and the bottom end of the threaded cylinder is slidably connected to the top end of the base. The V-shaped chuck is used to clamp and fix the pipe body.

[0008] Preferably, a third cylinder is installed at the top of the cabinet on the side of the base away from the positioning plate. One end of the third cylinder is provided with a rack, and one end of the bidirectional lead screw is provided with a gear. The gear and the rack mesh with each other, so that the rack drives the gear to rotate when it moves.

[0009] Preferably, a second motor is mounted on the top of the cabinet in front of the base via a bracket, and one end of the second motor is equipped with a belt drive mechanism so as to drive the belt drive mechanism to rotate.

[0010] Preferably, a rotating shaft is provided on the outer wall of the upper end of the belt drive mechanism, and a grinding head is installed at the end of the rotating shaft away from the belt drive mechanism. The grinding head is provided to grind the cut end of the pipe body.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the PVC pipe processing ring cutting equipment not only ensures the cutting accuracy of the pipe body when the ring cutting equipment is used, but also improves the convenience of using the ring cutting equipment, and ensures the smoothness of the pipe body cut.

[0012] (1) The left end of the pipe body is clamped and fixed by the three-jaw chuck. Then the second cylinder drives the limiting roller to tilt downward and move so that the limiting roller moves down to contact the outer wall of the pipe body. The right end of the pipe body can be clamped and limited by the limiting roller, which can effectively reduce the vibration generated during the circumferential cutting of the pipe body, thereby ensuring the cutting accuracy of the pipe body when the circumferential cutting equipment is used.

[0013] (2) The screw transmission mechanism is driven by the third motor to operate, so that the screw transmission mechanism drives the placement seat to move horizontally through the nut seat, so that the placement seat drives the pipe body held by the three-jaw chuck to move horizontally smoothly. Then the first cylinder is started to drive the drive arm to rotate, so that the drive arm drives the cutter to rotate and fit against the outer wall of the pipe body. Then the pipe body is driven to rotate by the first motor through the three-jaw chuck, so that the cutter can cut the pipe body to a specified length, thereby improving the convenience of using the circumferential cutting equipment.

[0014] (3) The rack is driven to rotate by the third cylinder. Because the rack and gear mesh with each other, the rack drives the double-acting screw to rotate through the gear. At this time, the two threaded cylinders slide towards each other on the outer wall of the double-acting screw, so that the threaded cylinders drive the V-shaped chucks to move closer to each other. The two V-shaped chucks clamp and fix the cut pipe body, and make the cut end of the pipe body fit against the outer wall of the grinding head. Then, the belt drive mechanism is driven by the second motor to run, so that the belt drive mechanism drives the grinding head to rotate through the rotating shaft. The grinding head can then perform grinding operations on the cut end of the pipe body, thereby ensuring the smoothness of the cut end of the pipe body. Attached Figure Description
