Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and in particular to a water jet cutting device for UPVC sleeves. Background Technology

[0002] The UPVC sleeve water jet cutting device is a specialized piece of equipment that uses high-pressure water jets mixed with abrasives (such as silica sand and garnet) to achieve efficient cold cutting. Its core structure includes a high-pressure power pump set, an abrasive mixing system, a gemstone or carbide nozzle, and a nozzle translation mechanism. By using the cold cutting characteristics to avoid thermal deformation of UPVC, combined with environmentally friendly designs such as noise reduction and protection, it achieves precise, safe, and low-consumption sleeve cutting operations.

[0003] Traditional nozzles (jewel or carbide nozzles) are directly mounted on the spray gun or mixing chamber via threads. Under high pressure, nozzles are consumable parts requiring frequent replacement. Existing methods involve cumbersome and time-consuming replacement processes, and the delicate internal seals or threads of the mixing chamber can be damaged during installation and removal, affecting system sealing and reliability. Frequent operation also increases the risk of human error, potentially leading to improper nozzle installation or tilting, affecting jet quality and cutting accuracy. Therefore, a water jetting and cutting device for UPVC sleeves is proposed to address these issues. Utility Model Content

[0005] Therefore, one objective of this utility model is to provide a water jet cutting device for UPVC sleeves to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of the present invention provides a water jet cutting device for UPVC sleeves, including a base, a bracket, and a track.

The guide wheels are movably connected to the outer surface of the synchronous belt. A crossbeam is fixedly connected between the sliding blocks, and a secondary seat is movably connected to the crossbeam; The position of the sub-seat on the crossbeam is adjustable; A pipe support is fixedly connected to the center of the top surface of the base, a mixing chamber is fixedly connected to the front of the sub-base, a feed pipe is fixedly connected to the top of the mixing chamber, an upper module is fixedly connected to the bottom of the mixing chamber, a lower module is detachably connected inside the upper module, and a nozzle is fixedly connected to the bottom of the lower module.

[0007] Preferably, in any of the above solutions, the base is welded to the bracket, and the track is made of aluminum alloy.

[0008] The above technical solution is adopted: This device is specially designed for water jet cutting of UPVC plastic pipes. The specific mechanism for performing the cutting work is the nozzle. At the same time, this device can perform vertical cutting at any point on the plastic pipe.

[0009] Preferably, in any of the above embodiments, the position of the slide on the track is adjustable, and the guide wheels are located on both sides below the drive wheel.

[0010] Brackets are fixedly connected to the four corners of the base's top surface, and rails are fixedly connected to the top of the brackets. Two parallel rails are movably connected to slides. A servo motor is fixedly connected to the back of the slides, and a drive wheel is fixedly connected to the front of the servo motor. Two sets of guide wheels are fixedly connected to the front of the slides. A timing belt is movably connected to the outer surface of the drive wheel, and both ends of the timing belt are fixedly connected to the two ends of the top surface of the rails. The guide wheels are movably connected to the outer surface of the timing belt. When the servo motor is started, the drive wheel rotates, driving the timing belt to move. With the assistance of the guide wheels, the slides move along the rails. A crossbeam is fixedly connected between the two slides, and a secondary seat is movably connected to the crossbeam.

Rotate the cam 20 to tighten the elastic section 17 inward to clamp the lower module 15, check the sealing performance, and ensure there is no leakage.

[0031] The UPVC plastic pipe to be cut is placed on the pipe support 11. According to the cutting requirements, the servo motor 5 is activated via the control system, adjusting the position of the slide 4 on the track 3 and the position of the auxiliary seat 10 on the crossbeam 9, so that the nozzle 16 is aligned with the part of the UPVC plastic pipe to be cut. A mixture of water and sand is fed into the mixing chamber 12 through the feed pipe 13.

The nozzle 16 is pre-installed within a standardized lower module 15, which contains a miniature Venturi tube and necessary sealing rings. This module, as a single unit, connects quickly to the upper module 14 via a quick-connect coupling. In actual production, when it's necessary to replace the nozzle 16 with a different specification or perform maintenance, simply rotate the cam 20 to loosen the elastic section 17, allowing for quick removal of the lower module 15. After replacing the lower module 15, rotating the cam 20 again tightens the elastic section 17, significantly reducing replacement time and improving production efficiency.
