Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, specifically a pipe cutting device for air conditioning insulation pipes. Background Technology

[0002] Air conditioning insulation pipes are an indispensable component of HVAC systems. Their main function is to wrap around the refrigerant pipes to reduce the loss of cooling or heating and prevent condensation from forming on the pipe surface, thereby saving energy and protecting the pipes. During the installation and manufacturing of air conditioners, the insulation pipes, whether rolled or in sections, need to be precisely cut according to the actual pipe length. To improve cutting efficiency and accuracy, some automated or semi-automated pipe cutting devices have appeared on the market to replace the traditional manual cutting method.

[0003] However, the clamping mechanism of some equipment has poor adaptability to pipe diameter, and unstable clamping can easily cause the pipe to tilt during transportation, resulting in a skewed cut and affecting the subsequent installation quality. At the same time, the accuracy and stability of the feeding mechanism directly affect the consistency of the cutting length. Traditional feeding methods are prone to slippage or error accumulation. In addition, the debris generated during the cutting process is difficult to collect and clean, affecting the cleanliness of the working environment. Therefore, an air conditioning insulation pipe cutting device is needed to solve the existing shortcomings. Utility Model Content

[0015] An upper clamping plate is disposed above the lower clamping plate;

[0016] The surfaces of the upper and lower clamping plates that face each other are V-shaped structures, together forming a clamping area for accommodating the tube.

[0017] A drive assembly, connected to the upper clamping plate, is used to drive the upper clamping plate to move vertically up and down relative to the lower clamping plate, so as to adjust the size of the clamping area.

[0018] Furthermore, the driving component includes:

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] like Figure 1-4 As shown, this utility model provides a technical solution: an air conditioning insulation pipe cutting device, including a stable base 1, which can be welded from steel plates to provide support for the entire device. A clamping mechanism is fixedly installed in the middle and rear part of the base 1. This clamping mechanism is the core of the device and is used to fix and transport the pipe body 2 to be cut. It includes a lower clamping plate 3 fixed to the top of the base 1 by bolts, and a V-shaped groove is machined on the top surface of the lower clamping plate 3. Directly above the lower clamping plate 3, a matching upper clamping plate 4 is provided, and the bottom surface of the upper clamping plate 4 also has a V-shaped groove. The V-shaped grooves of the upper clamping plate 4 and the lower clamping plate 3 face each other, together forming a variable clamping area for accommodating and clamping the cylindrical insulation pipe body 2.

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, in order to drive the upper clamping plate 4 to rise and fall, this embodiment provides four guide rods 5, which are fixed at the four corners of the lower clamping plate 3. The upper clamping plate 4 has through holes at corresponding positions, movably fitted onto the guide rods 5, ensuring that the upper clamping plate 4 can only move precisely vertically along the guide rods 5. Two hydraulic cylinders 6 are symmetrically fixed on both sides of the bottom of the lower clamping plate 3. The telescopic rods of these two hydraulic cylinders 6 extend upwards and are fixed to the bottom side of the upper clamping plate 4. When the telescopic rods of the hydraulic cylinders 6 extend, they push the upper clamping plate 4 upwards along the guide rods 5, increasing the clamping area; when the telescopic rods retract, they pull the upper clamping plate 4 downwards, adaptively clamping the tube 2. This V-shaped clamping structure can automatically center, thereby limiting the forward direction of tubes 2 of different sizes by controlling the size of the clamping area, allowing the tube 2 to move axially and preventing the tube 2 from tilting during forward movement, which would cause the cut surface of the tube 2 to also tilt.

[0048] like Figure 1 , Figure 2 and Figure 3As shown, elongated receiving grooves 10 are axially formed at the V-shaped inclined edges of the upper clamping plate 4 and the lower clamping plate 3. An auxiliary moving assembly is installed within each receiving groove 10. This assembly includes a pair of synchronous pulleys 11 mounted at both ends of the receiving groove 10 via bearings and a rotating shaft, and a synchronous belt 12 wrapped around the outside of the two synchronous pulleys 11. The outer surface (working surface) of the synchronous belt 12 is slightly higher than the surface of the V-shaped groove so that it can make close contact with the outer wall of the tube body 2 during clamping.

[0049] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment employs a built-in design to drive the synchronous belt 12. A servo motor 13 is fixedly mounted with screws inside one end of each receiving slot 10. The output shaft of the servo motor 13 is directly connected to the shaft of one of the synchronous pulleys 11 via a coupling. When the servo motor 13 starts, it drives the synchronous pulley 11 to rotate, thereby causing the entire synchronous belt 12 to circulate within the receiving slot 10. Because the synchronous belt 12 of the upper and lower clamping plates 3 tightly wraps around the tube body 2 from both sides, the friction generated when the synchronous belt 12 rotates drives the tube body 2 to move forward steadily and precisely along its axial direction until it is fed into the cutting position. By embedding the servo motor 13 within the receiving slot 10, the overall size of the device is greatly reduced, resulting in a more compact structure.

[0050] On the top front side of the base 1, directly opposite the discharge port of the clamping mechanism, a cutting mechanism is installed. This mechanism includes a U-shaped support frame 7, which is bolted to the base 1. Inside the support frame 7, a cutter 8 is movably mounted; the cutter 8 can be a sharp, straight blade. At the top of the support frame 7, a hydraulic cylinder 9 is fixedly installed, its telescopic rod passing downward through the top plate of the support frame 7 and fixedly connected to the top of the cutter holder of the cutter 8. When the tube 2 is delivered to the predetermined position, the telescopic rod of the hydraulic cylinder 9 quickly extends, driving the cutter 8 to cut vertically downward, completing the severing of the tube 2.

[0051] like Figure 1 , Figure 2 and Figure 3As shown, to solve the problem of cutting debris, this embodiment designs a debris collection mechanism. At the bottom of the V-shaped structure of the lower clamping plate 3, a through groove 14 is formed along its length. Debris generated by friction between the tube 2 and the timing belt 12 or the clamping plate during the tube's forward movement will slide down the inner wall of the V-shape of the lower clamping plate 3 due to gravity, eventually collecting at the bottom through groove 14 and falling down. At the bottom of the base 1, corresponding to the position of the through groove 14, a receiving box 15 is designed and detachably installed below the base 1. All debris falling from the through groove 14 will fall into the receiving box 15. When the debris accumulates to a certain level, the operator only needs to pull the receiving box 15 from the base 1 to easily dispose of the debris uniformly, achieving a clean and environmentally friendly production process.

[0052] The workflow is as follows:

[0053] First, the operator sets relevant parameters through the control system (such as a PLC or touch screen) according to the diameter of the insulated pipe 2 to be cut. Then, the control system drives the extension rods of the two hydraulic cylinders 6 to extend, pushing the upper clamping plate 4 vertically upward along the four guide rods 5, so that the V-shaped clamping area between the upper and lower clamping plates 3 opens to a sufficiently large size. Then, the operator places the pipe 2 to be cut from the rear end of the clamping mechanism, allowing it to fall naturally into the V-shaped groove of the lower clamping plate 3.

[0054] Secondly, after the tube body 2 is inserted, the control system activates hydraulic cylinder 6, whose telescopic rod retracts, pulling the upper clamping plate 4 down smoothly. Since both the upper and lower clamping plates 3 are V-shaped structures, during the descent of the upper clamping plate 4, the V-shaped surface automatically guides the tube body 2 to the center position, achieving automatic centering. When the upper clamping plate 4 descends to the preset position, the tube body 2 is appropriately clamped. This clamping method not only fixes the tube body 2, but more importantly, restricts its forward direction, ensuring that the tube body 2 can move strictly along its axial direction, effectively avoiding skewing during the feeding process and guaranteeing the perpendicularity of the subsequent cutting surface from the source.

[0055] Next, after the clamping action is completed, the control system issues a command to start the servo motor 13 installed in the receiving groove 10 of the upper clamping plate 4 and the lower clamping plate 3. The servo motor 13 drives the synchronous pulley 11 to rotate through the coupling, which in turn drives the synchronous belt 12 to rotate cyclically within the receiving groove 10. Since the working surfaces of the upper and lower synchronous belts 12 are tightly attached to the outer wall of the tube body 2 from both sides, the friction generated when the synchronous belts 12 rotate will drive the tube body 2 to move forward steadily and accurately along its axial direction until the part to be cut is delivered directly below the cutter 8. The servo motor 13 ensures high precision in the feeding length.

[0056] Next, when the tube 2 reaches the preset cutting position, the servo motor 13 stops rotating. The hydraulic cylinder 2 9, fixed to the top of the support frame 7, starts, and its telescopic rod quickly extends downward, driving the sharp straight blade to cut vertically downward, instantly completing the cutting of the tube 2.

[0057] Next, after the cutting is completed, the telescopic rod of hydraulic cylinder 2 9 immediately retracts, driving the cutter 8 to return to its initial high position. During this process, all debris generated by the friction between the pipe body 2 and the clamping plate will slide down the V-shaped inner wall of the lower clamping plate 3 due to gravity, eventually collecting at the bottom through groove 14 and falling into the detachable receiving box 15 below, achieving clean and environmentally friendly debris collection.

[0058] Finally, after resetting, the servo motor 13 restarts, driving the synchronous belt 12 to deliver the cut finished pipe segment, while simultaneously sending the next section to be cut to the cutting position. The device automatically returns to step two and begins the next cutting cycle until all set tasks are completed. When the debris in the receiving box 15 accumulates to a certain level, the operator can remove it from the base 1 at any time for unified cleaning.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
