Technical Field

[0001] The utility model relates to the technical field of HVAC engineering, and more specifically to a HVAC pipe cutting machine for HVAC engineering. Background Art

[0002] HVAC engineering refers to the design, installation and maintenance of heating, ventilation and air-conditioning systems inside buildings. These systems are designed to ensure comfort and air quality inside buildings to meet people's living and working needs. HVAC engineering usually involves knowledge in fields such as thermodynamics, fluid mechanics, aerodynamics, etc., and aims to provide buildings with suitable temperature, humidity and air flow. The pipes used for heating / cooling systems in HVAC usually transport media such as hot water, steam, and chilled water to deliver heat / cooling media to various parts of the building, ensuring that all areas inside the building can obtain proper heating, thereby providing a comfortable indoor environment.

[0003] The shortcomings of the existing technology: In the production process of HVAC pipes, the cutting link is crucial. The traditional pipe cutting method generally adopts manual operation, which is not only inefficient but also difficult to ensure accuracy. In the production process, workers need to hold a handheld cutting machine to cut along the length of the pipe. Due to the influence of factors such as the operator's skill level and work experience, the cutting accuracy and consistency often cannot reach the ideal state. In addition, the traditional method is also prone to scratches and damage on the surface of the pipe, thereby affecting the quality and service life of the pipe. Therefore, it is necessary to design a HVAC pipe cutting machine for HVAC engineering. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is provided with a placement mechanism, and the V-shaped bracket and the V-shaped connecting frame provide necessary support and stability for the pipe to be cut during the cutting process of the HVAC pipe workpiece, thereby ensuring the accuracy of the position and direction of the pipe during the cutting process.

The edge of the pipe after cutting is smooth and burr-free, which lays a good foundation for subsequent assembly work, reduces production costs, and ensures product quality.

The V-shaped bracket 501 and the V-shaped connecting frame 502 are used to place the HVAC pipe workpiece to be cut, which can provide the support and stability required for the pipe, while ensuring that the pipe maintains the correct position and direction during the cutting process. The V-shaped bracket 501 and the V-shaped connecting frame 502 can effectively fix the pipe, and the pad 503 helps to balance the weight of the pipe and provide additional support.

[0025] Furthermore, a flip bracket 504 is fixedly connected to the bottom of the front side of the V-shaped bracket 501, and the V-shaped bracket 501 is rotatably connected to the support frame 2 through the flip bracket 504. A flip cylinder 505 is fixedly connected to the bottom of the rear side of the middle V-shaped bracket 501, and the bottoms of the rear sides of the V-shaped brackets 501 on both sides are fixedly connected to limit seats 506. The bottoms of the limit seats 506 are correspondingly provided with shock-absorbing pads 507. When the cutting mechanism 6 completes the cutting of the HVAC pipe, the flip cylinder 505 is started to lift one side of the V-shaped bracket 501. With the cooperation of the flip bracket 504, the V-shaped bracket 501 can be flipped and The material unloading operation allows the cut pipe to be smoothly transferred to the next process. After the flipping is completed, the flipping cylinder 505 retracts, driving the V-shaped bracket 501 to fall, so that the limit seat 506 falls on the shock-absorbing pad 507. During the falling process, the shock-absorbing pad 507 can reduce the impact force to ensure the stability and safety of the falling process, and effectively avoid damage to the V-shaped bracket 501 due to excessive impact force.

[0027] Furthermore, a slide rail 605 is fixedly connected to the bottom of the base plate 603, and a cutting knife assembly 606 is slidably connected to the slide rail 605. The cutting knife assembly 606 corresponds to the V-shaped connecting frame 502. During the cutting process, the cutting knife assembly 606 can flexibly move back and forth on the slide rail 605, thereby improving the cutting range and accuracy, thereby improving the cutting efficiency.

[0028] Furthermore, the limiting mechanism 7 includes an electric telescopic rod 701 and an arc-shaped limiting plate 702. The electric telescopic rod 701 is fixedly mounted on the mounting plate 602. The telescopic end of the electric telescopic rod 701 is fixedly connected with the arc-shaped limiting plate 702. The arc-shaped limiting plate 702 corresponds to the V-shaped bracket 501. When cutting, the electric telescopic rod 701 drives the arc-shaped limiting plate 702 to move downward.
