[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 and Figure 2 As shown, a pipe cutting device for building HVAC construction includes a control console 1, a matching component 2 is fixedly connected to the rear end of the control console 1, a cutting component 3 is fixedly connected to the rear end of the matching component 2, two support components 1 5 arranged in a mirror image are fixedly connected to the upper end of the matching component 2, a support component 2 6 is slidably connected to the upper part of the matching component 2, and cleaning components 4 are fixedly connected to the left and right sides of the cutting component 3.

[0033] First, by adjusting the specific parameters of the control console 1, and then by controlling the control console 1, the two matching components 2 can be moved to the left and right sides. At this time, the operator can insert the HVAC pipe to be cut into the left and right sides of the two support components 1 5, and then place the HVAC pipe to be cut on the upper surface of the support component 2 6, so that the HVAC pipe to be cut will cause the support component 2 6 to drop by its own weight, and then during the process of the support component 2 6 dropping, it will cooperate with the internal components of the support component 1 5, so that the two support components 1 5 close to each other support the inner wall of the HVAC pipe to be cut. Secondly, the operator can control the cutting component 3 to drive the cleaning component 4 to move left and right, so as to reach a suitable cutting position, and then cut the HVAC pipe to be cut;

[0034] Furthermore, by setting up a support component 1 5 and a cleaning component 4 for cooperation, the surface of the HVAC pipe to be cut can be cleaned, and then by cleaning the oil, dust and other impurities on the surface, the cutting device in the cutting component 3 can be better in contact with the pipe surface, reducing the cutting deviation and ensuring that the cutting line is straight and smooth. Further, by setting up a support component 1 5 and a support component 2 6 for cooperation, it can be automatically adjusted according to the specific size of the HVAC pipe, thereby ensuring the positioning of the HVAC pipe during the cutting process, avoiding the traditional manual measurement and adjustment of the pipe size which requires a lot of time and effort, and speeding up the entire construction process.

[0035] The control console 1 mentioned above is a mature control technology means and equipment in the prior art. In this solution, the controllable functions thereof are utilized, and its structure, connection mode and principle are not further elaborated.

[0036] For details, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the cutting assembly 3 includes a support block 31, an adjusting assembly 33 is fixedly connected to the middle of the upper end of the support block 31, a protective plate 32 is fixedly connected to the rear of the upper end of the support block 31, the adjusting assembly 33 includes a hydraulic cylinder 331, a matching block 332 is fixedly connected to the bottom end of the hydraulic cylinder 331, a sliding column 333 is slidably connected to the upper front end of the hydraulic cylinder 331, a motor 334 is fixedly connected to the front end of the sliding column 333, a cutting blade 336 is fixedly connected to the transmission shaft through a coupling at the output end of the motor 334, and a protective shell 335 is fixedly connected to the left side of the motor 334.

[0037] For further information, see Figure Figure 2 , Figure 3 , Figure 4 and Figure 6 In this embodiment, after the HVAC pipe to be cut is placed on the outer surface of the two support components 1 5, the operator can then control the power source inside the support component 1 5 to start through the console 1, so that the cleaning component 4 can clean the surface of the pipe, and then control the motor 2 43 to rotate, so that through the cooperation of the motor 2 43 and the threaded rod 44, the matching block 332 can be controlled to move left and right, so that its cutting position can be adjusted. After further position adjustment, the hydraulic cylinder 331 will push the sliding column 333 to move in the direction of the HVAC pipe to be cut, and then start the motor 1 334, thereby driving the cutting blade 336 to rotate, so that the HVAC pipe can be cut;

[0038] By setting the motor 2 43 to drive the threaded rod 44 to rotate during the rotation process, the threaded rod 44 cooperates with the bottom end of the matching block 332, so that the device can adjust the cutting size at any time according to the actual situation;

[0039] In addition, the motor 2 43 mentioned above is of conventional design in the prior art, and in this solution, only its transmission function is utilized, and its working principle will not be elaborated in detail.

[0040] For further information, see Figure 3 , Figure 4 , Figure 5As shown, the cleaning component 4 includes a fixed block 41, the left side of the fixed block 41 is fixedly connected to the right side of the hydraulic cylinder 331, the left side of the hydraulic cylinder 331 is fixedly connected to a fixed block 2 42, the fixed block 41 and the front side of the fixed block 2 42 are slidably connected with a wiping component 45, the inner cavity of the matching block 332 is threadedly connected with a threaded rod 44, the left side of the threaded rod 44 is fixedly connected with a motor 2 43, the wiping component 45 and the inner cavity of the fixed block 41 both include a sliding rod 451, the front ends of the outer surfaces of the two sliding rods 451 are fixedly connected to a fixed plate 452, the front sides of the two fixed plates 452 are fixedly connected to a spring 453, the front ends of the two sliding rods 451 are movably connected to a connecting shell 454, and the front ends of the two connecting shells 454 are commonly fixedly connected with an arc-shaped wiping plate 455.

[0041] For further information, see Figure 3 , Figure 4 , Figure 5 As shown in FIG. 2 , in this implementation process, when the operator places the HVAC pipe to be cut on the upper side of the support assembly 2 6 , the HVAC pipe to be cut will slide backwards due to its own gravity, and the spring 453 provided at the front of the fixing plate 452 will make the arc-shaped wiping plate 455 always press against the HVAC pipe to be cut due to its own resilience, thereby continuously cleaning the HVAC pipe to be cut;

[0042] In addition, it should be noted that the arc-shaped wiping plate 455 should be moistened during use so as to achieve the purpose of cleaning or clearing the surface of the HVAC pipe to be cut. The moistening liquid can be a special detergent, alcohol or water for cleaning to ensure that the pipe surface is clean. Subsequently, when cutting, the moistened HVAC pipe surface can also reduce the heat generated by the cutting blade 336 during cutting, reduce the thermal impact during cutting, and avoid deformation, burning or uneven cutting surface of the pipe material caused by excessive temperature;

[0043] Secondly, the front ends of the two sliding rods 451 mentioned above are movably connected to a connecting shell 454. The movable connection here can be understood as a semi-rotating connection, which means that after the arc-shaped wiping plate 455 is against the HVAC pipe to be cut, it can be slightly adjusted to make the contact area between the arc-shaped wiping plate 455 and the HVAC pipe to be cut larger. There is a certain resistance at the connection, and it only needs to be able to achieve slight adjustment while resisting the HVAC pipe to be cut.

[0044] Embodiment 2: This embodiment achieves the purpose of positioning and automatically adjusting the HVAC pipe to be cut while supporting it internally on the basis of Embodiment 1. For further information, please refer to Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the support component 1 5 includes a fixed block 3 51, the upper end of the fixed block 3 51 is fixedly connected to a motor 3 52, the output end of the motor 3 52 is fixedly connected to a connecting rod 53 through a coupling, the outer surface of the connecting rod 53 is slidably connected to an adjusting component 2 54, the middle part of the outer surface of the connecting rod 53 is slidably connected to a sliding block 55, the outer surface of the sliding block 55 is rotatably connected to three connecting strips 1 56, the right part of the outer surface of the connecting rod 53 is fixedly connected to a fixed block 4 58, the outer surface of the fixed block 4 58 is rotatably connected to three connecting strips 2 59, the intersection of the three connecting strips 2 59 and the three connecting strips 1 56 is rotatably connected to an arc-shaped supporting plate 57, the adjusting component 2 54 includes a calibration disk 541, the bottom of the outer surface of the calibration disk 541 is fixedly connected to a sliding rod 2 542, the front and rear sides of the bottom of the sliding rod 2 542 are fixedly connected to sliding bars 543, and the left side of the sliding rod 2 542 is fixedly connected to a pushing plate 544, and the support component 2 6 includes a telescopic component 61, and the bottom end of the telescopic component 61 is slidably connected to a box The box body 1 62 has three connecting tubes 63 fixedly connected to the bottom end thereof, and the other ends of the three connecting tubes 63 are fixedly connected to the box body 2 64. The telescopic component 61 comprises two sliding plates 1 611, and the upper ends of the two sliding plates 1 611 are fixedly connected to the support platform 1 612, and the sides of the two support platforms 1 612 close to each other are fixedly connected to the sliding groove 2 613, and the sides of the two sliding grooves 213 close to each other are slidably connected to the sliding plate 2 614, and the upper ends of the sliding plates 2 614 are fixedly connected to two support platforms 2 615, and the upper sides of the two support platforms 1 612 and the two support platforms 2 615 are rotatably connected to three balls 616. The matching component 2 comprises two fixed tables 21, and the sliding grooves 1 22 are provided on the front and rear sides of the middle parts of the inner surfaces of the two fixed tables 21, and the sides of the two fixed tables 21 close to each other are provided with loading grooves 23, and the left side of the right fixed table 21 is fixedly connected to the hydraulic rod 24, and the bottom left side of the right fixed table 21 is fixedly connected to two rails 25.

[0045] Specifically, in the present implementation process, when the operator inserts the HVAC pipe to be cut into the side where the two support assemblies 5 are close to each other, the ball 616 will be driven by the weight of the HVAC pipe to be cut to drive the two support platforms 1 612 and the two support platforms 2 615 connected at the bottom to move downward, and then the two sliding plates 1 611 will be driven to move downward in the process of the two support platforms 1 612 on the left and right sides moving downward, so that the two sliding plates 1 611 will squeeze the hydraulic oil in the inner cavity of the box body 1 62, thereby forcing the hydraulic oil to enter the corresponding inner cavity of the box body 2 64 through the three connecting pipes 63, and then the hydraulic oil will push the push plate 544, so that the two The sliding rod 2 542 moves toward the side close to each other, so that the two alignment disks 541 clamp the HVAC pipe to be cut. Further, when the two alignment disks 541 approach each other, they will push the sliding block 55 slidably connected to the outer surface of the connecting rod 53. When the two sliding blocks 55 slide toward the side close to each other, the three connecting strips 1 56 and the three connecting strips 2 59 will cooperate, so that the arc-shaped support plate 57 rotatably connected at the intersection of the three connecting strips 2 59 and the three connecting strips 1 56 is lifted up, so as to support the inner wall of the HVAC pipe to be cut. Then, the control console 1 will control the cutting blade 336 to cut the HVAC pipe to be cut.

[0046] Furthermore, by setting the telescopic component 61, after being subjected to the gravity of the HVAC pipe to be cut, the hydraulic oil in the inner cavity of the box 1 62 can be pushed to move, so that the two alignment plates 541 can clamp the two ends of the HVAC pipe to be cut, thereby reducing the dependence on manual operation. The operator only needs to place the pipe, and the device will automatically complete the clamping action, thereby improving work efficiency and reducing the risk of human error. Further, the inner cavity of the HVAC pipe to be cut is supported by three arc-shaped support plates 57, so as to avoid deformation or bending of the pipe due to excessive local force, and ensure that the pipe maintains its original shape and structure during cutting;

[0047] It should be further explained that the arc-shaped surfaces of the two support platforms 1 612 and the two support platforms 2 615 are each provided with three ball bearings 616. Thus, compared with the plane support in direct contact, the ball bearings 616 can reduce frictional resistance, reduce energy consumption, and reduce wear on the pipe surface. In this device, it is only necessary to avoid affecting the two motors 3 52 in driving the HVAC pipes to be cut for rotational cutting.

[0048] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
