Description

Technical Field

[0001] This utility model belongs to the field of pipeline laser cutting technology, and in particular relates to a cutting device for the production of anti-electric shock wall insulated water inlet pipes. Background Technology

[0002] The anti-electric shock insulated water inlet pipe is a type of pipe made of non-conductive materials. Its core function is to block the conduction of current through water flow, preventing the risk of electric shock or equipment damage caused by leakage. Through physical insulation and structural design, this pipe ensures "water and electricity separation" in water-related electrical appliances, meets electrical safety standards, and is widely used in high-safety scenarios such as homes, industries, and medical settings.

[0003] In the processing of insulated water inlet pipes for anti-electric shock walls, traditional laser cutting technology has the following problems: high laser temperature can easily cause carbonization, melting or micro-cracks at the pipe cutting location, damaging the integrity of the insulation layer and reducing the pressure resistance performance; local high temperature can cause pipe shrinkage or warping, affecting the sealing of the interface and assembly accuracy; thermal damage may form conductive channels, weakening the electrical isolation effect of the pipe and increasing safety hazards; existing equipment does not deeply integrate the pre-cooling module with the cutting process, resulting in uneven cooling or excessive energy consumption.

[0004] To address this issue, we provide a cutting device for producing anti-electric shock insulated water inlet pipes, thereby solving the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting device for the production of anti-electric shock wall insulated water inlet pipes. Through the cooperation of the drive mechanism and the pre-cooling mechanism, it solves the problems in the existing cutting devices, such as the high temperature of the laser causing carbonization, melting or micro-cracks at the pipe cutting position, which damages the integrity of the insulation layer, reduces the pressure resistance, and the local high temperature causing the pipe to shrink or warp, affecting the sealing of the interface and the assembly accuracy.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a cutting device for producing anti-electric shock wall insulating water inlet pipes, comprising a cutting box, a clamping and rotating mechanism on one side of the top of the cutting box, a laser cutter on the top of the clamping and rotating mechanism, a pushing mechanism on one side of the top of the cutting box, and a driving mechanism on the top of the cutting box. The driving mechanism includes a sliding cylinder on one side of the cutting box, a driving plate fixedly connected to the top of the sliding cylinder, and a precooling box at the bottom of the driving plate. The precooling box contains a precooling mechanism, which includes a precooling pipe fixedly connected to the inside of the precooling box, a precooling nozzle connected to the surface of the precooling pipe, a storage box on one side of the cutting box, and a booster pump connected to the top of the storage box.

[0008] The present invention is further configured such that a support plate is fixedly connected to one side of the cutting box, and the slide cylinder is fixedly connected to the top of the support plate.

[0009] The present invention is further configured such that a tube-through drag chain is fixedly connected to one side of the top of the support plate, and a conveying pipe is provided inside the tube-through drag chain.

[0010] The present invention is further configured such that a hydraulic cylinder is fixedly connected to the top of the drive plate, and the output end of the hydraulic cylinder is fixedly connected to the top of the precooling box.

[0011] The present invention is further configured such that the bottom of the precooling box is open, the interior of the precooling box has an arc-shaped groove, and the precooling pipe is semi-circular.

[0012] The present invention is further configured such that there are two precooling pipes, and the two precooling pipes are connected by a connecting pipe.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model utilizes a coordinated design of a pre-cooling mechanism and a drive mechanism, employing liquid nitrogen atomization spray technology for dynamic pre-cooling of the cutting area. The pre-cooling chamber incorporates a semi-annular pre-cooling pipe with a dual-nozzle layout, combined with the lateral positioning of the slide cylinder and the vertical adjustment of the hydraulic cylinder, achieving precise coverage of the cutting path. Pre-cooling liquid nitrogen is delivered from the storage tank to the pre-cooling pipe via a booster pump, instantly lowering the pipe surface temperature and creating a uniform low-temperature layer in the cutting area. This design effectively suppresses the thermal effects during laser cutting, preventing carbonization, melting, and micro-cracks in the insulation layer, ensuring a smooth and flat cutting surface, and avoiding interface sealing failure caused by pipe thermal deformation.

[0015] 2. This invention achieves full automation of the cutting pre-cooling process through the coordinated control of the sliding table cylinder, hydraulic cylinder, and pre-cooling chamber. The sliding table cylinder drives the pre-cooling chamber to move synchronously along the pipeline axis, the hydraulic cylinder adjusts the pre-cooling height in real time, the flexible delivery pipe built into the pipe-through drag chain ensures the stability of liquid nitrogen supply, and the dual pre-cooling pipes are connected by a connecting pipe to balance the pressure and ensure consistent flow rate of each nozzle. This dynamic following system controls the error between the pre-cooling area and the laser cutting trajectory within ±0.1mm, improving cooling uniformity. Combined with the circumferential positioning of the clamping and rotating mechanism, it eliminates the risk of localized overheating.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Please see Figures 1-4 This utility model is a cutting device for producing anti-electric shock wall insulated water inlet pipes, including a cutting box 1, a clamping and rotating mechanism 2 is provided on one side of the top of the cutting box 1, a laser cutter 3 is provided on the top of the clamping and rotating mechanism 2, a pushing mechanism 4 is provided on one side of the top of the cutting box 1, and a driving mechanism is provided on the top of the cutting box 1. The driving mechanism includes a slide cylinder 5 provided on one side of the cutting box 1, a driving plate 6 fixedly connected to the top of the slide cylinder 5, and a precooling box 7 provided at the bottom of the driving plate 6. The precooling box 7 is provided with a precooling mechanism, which includes a precooling pipe 8 fixedly connected to the inside of the precooling box 7, a precooling nozzle 9 connected to the surface of the precooling pipe 8, a storage box 10 provided on one side of the cutting box 1, and a booster pump 11 connected to the top of the storage box 10.

[0026] Specifically: Through the setting of the drive mechanism, the coordinated action of the slide cylinder 5 and the hydraulic cylinder 15 achieves precise positioning and dynamic following of the precooling box 7, ensuring strict matching between the precooling area and the cutting path. Through the setting of the precooling mechanism, liquid nitrogen atomization and uniform coverage technology are used to precool and cool the pipe cutting position, thereby avoiding rapid heating of the pipe during laser cutting and ensuring the insulation performance and geometric accuracy of the pipe. The combination of the drive mechanism and the precooling mechanism solves the insulation failure problem caused by heat effect in traditional laser cutting, providing a reliable solution for the high-quality production of anti-electric wall insulated water inlet pipes.

[0027] Example 2

[0028] Please see Figures 1-4 Based on embodiment 1, a support plate 12 is fixedly connected to one side of the cutting box 1, a slide cylinder 5 is fixedly connected to the top of the support plate 12, a tube drag chain 13 is fixedly connected to one side of the top of the support plate 12, a conveying pipe 14 is provided inside the tube drag chain 13, one end of the conveying pipe 14 is connected to the precooling pipe 8, and the other end of the conveying pipe 14 is connected to the booster pump 11. A hydraulic cylinder 15 is fixedly connected to the top of the drive plate 6, and the output end of the hydraulic cylinder 15 is fixedly connected to the top of the precooling box 7. The bottom of the precooling box 7 is an open design, and an arc-shaped groove is opened inside the precooling box 7. The precooling pipe 8 is semi-circular in shape, and there are two precooling pipes 8. A connecting pipe 16 connects the two precooling pipes 8.

[0029] Specifically: The support plate 12 is used to fix the slide cylinder 5 and the pipe drag chain 13. The pipe drag chain 13 is used to protect the delivery pipe 14 to prevent damage caused by continuous friction when adjusting the precooling position. The delivery pipe 14 is used to deliver liquid nitrogen to the precooling pipe 8. The hydraulic cylinder 15 is used to drive the precooling box 7 to move up and down. The precooling box 7 with its open bottom and arc-shaped groove allows the pipe to be cut to enter the precooling box 7 for precooling. The connecting pipe 16 connects the two precooling pipes 8 to facilitate the delivery of liquid nitrogen.

[0030] The working principle of this utility model is as follows: the pipe to be cut is placed inside the pushing mechanism 4, the pushing mechanism 4 pushes the pipe to the clamping and rotating mechanism 2 for clamping and limiting, the pipe cutting position is set in the external controller, the controller drives the slide cylinder 5 to move, the slide cylinder 5 drives the precooling box 7 to move towards the pipe cutting position, the hydraulic cylinder 15 drives the precooling box 7 to move downward, so that the precooling box 7 is located on the surface of the pipe cutting position, at which time the pipe is located inside the precooling box 7.

[0031] The booster pump 11 delivers liquid nitrogen stored in the storage tank 10 to the precooling pipe 8 through the delivery pipe 14. Liquid nitrogen is sprayed through the precooling nozzle 9 on the precooling pipe 8. The liquid nitrogen contacts the pipe and cools the pipe cutting position. The clamping and rotating mechanism 2 drives the pipe to rotate, so that the pipe circumference is cooled evenly. After the cooling is completed, the hydraulic cylinder 15 retracts and drives the precooling box 7 to move upward. At this time, the pushing mechanism 4 pushes the precooled pipe to the bottom of the laser cutter 3. The laser cutter 3 performs laser cutting on the precooled pipe. Since the pipe cutting position has been precooled, the temperature can be effectively prevented from rising rapidly during laser cutting, thus protecting the pipe cutting position.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
