Description

Technical Field

[0001] This invention relates to the field of heat exchanger copper tube manufacturing technology, and in particular to a heat exchanger copper tube end cutting device. Background Technology

[0002] In the manufacturing process of automotive air conditioning systems, heat exchange copper tubes, as core heat exchange components, directly affect the heat exchange efficiency and operational reliability of the air conditioning system due to their structural shape and processing quality. Because the interior space of a car is extremely limited, all components of the air conditioning system must strictly adhere to compact layout requirements. This often necessitates that heat exchange copper tubes exhibit irregular shapes in practical applications to adapt to the narrow and complex interior installation environment.

[0003] Irregularly shaped heat exchange copper tubes are typically formed by welding multiple copper tubes together. To facilitate the welding process and ensure the final irregularly shaped structure meets design requirements, the cut ends of the copper tubes usually need to be designed as irregularly shaped ports. However, in existing technologies, the processing of irregularly shaped ports mainly relies on a combination of traditional cutting techniques and manual grinding. Operators first use a cutting machine to roughly cut the ends of the copper tubes, initially forming a contour close to the target shape. However, due to the limitations of mechanical cutting precision and the characteristics of the copper tube material, the cut ends often have burrs, unevenness, or shape deviations, requiring subsequent manual grinding for fine processing to meet the requirements. When using the above processing method, the manual grinding process is time-consuming, requires a high level of skill from the operators, is labor-intensive, and has low operating efficiency.

[0004] Therefore, those skilled in the art are dedicated to developing a heat exchanger copper tube end cutting device that facilitates rapid cutting of irregular ends and improves the processing efficiency of heat exchanger copper tubes. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a heat exchanger copper tube end cutting device, which facilitates the rapid cutting of irregular ends and improves the processing efficiency of heat exchanger copper tubes.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a heat exchanger copper tube end cutting device, comprising... A first longitudinal clamping assembly and a second longitudinal clamping assembly are mounted on a frame and arranged opposite to each other, and a synchronization assembly is installed between the first longitudinal clamping assembly and the second longitudinal clamping assembly. A lateral clamping assembly, which is mounted on the frame and located on the sidewalls of the first longitudinal clamping assembly and the second longitudinal clamping assembly; A high-frequency vibration assembly is mounted on the frame, and the actuating end of the high-frequency vibration assembly is used to abut against the copper tube. A rotating assembly, on which the frame is mounted; A cutting assembly, which is mounted on a base and used to cut the ends of copper tubes.

[0007] The beneficial effects of adopting the above scheme are: by setting the first longitudinal clamping component and the second longitudinal clamping component relative to each other and cooperating with the synchronization component, it is possible to achieve stable central clamping and precise positioning of the copper tube; The lateral clamping assembly provides auxiliary clamping force from the side, forming multi-dimensional constraints to prevent the copper tube from shaking during the cutting process; The high-frequency vibration component acts on the copper tube through high-frequency vibration, which can significantly reduce cutting resistance and reduce burr generation; The rotating component drives the frame to rotate the copper tube, which, together with the cutting component, enables continuous forming and cutting of irregularly shaped ports, achieving automated processing of irregularly shaped ports and improving processing efficiency.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, both the first longitudinal clamping assembly and the second longitudinal clamping assembly include clamping wheels, each clamping wheel having a tapered clamping groove with anti-slip texture. The clamping wheels are mounted on the moving assembly via a mounting bracket, and a feeding servo power assembly is also mounted on the side wall of one of the clamping wheels.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the use of a clamping wheel with a conical clamping groove can adapt to the self-centering clamping of copper tubes of different diameters, and the conical structure facilitates the dual function of axial positioning and radial clamping. The anti-slip texture on the clamping groove enhances the clamping friction and prevents the copper tube from slipping during the rotary cutting process; The servo power unit drives the clamping wheel to rotate, which facilitates automatic feeding of copper tubes and improves the degree of automation and production efficiency.

[0011] Furthermore, the moving component includes a slider mounted on the side wall of the mounting bracket, the frame having a vertical mounting plate, and a slide rail that mates with the slider mounted on the vertical mounting plate; A guide sleeve and a guide rod are also installed between the mounting bracket and the frame. A spring is sleeved on the guide sleeve and the guide rod, and the two ends of the spring abut against the mounting bracket and the frame, respectively.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the slider and the slide rail cooperate to realize the smooth movement of the clamping wheel, which is convenient to adapt to the clamping requirements of copper tubes of different specifications; The elastic guiding structure composed of the guide sleeve, guide rod and spring enables the clamping wheel to automatically adjust the clamping position according to the shape of the copper tube, realizing flexible adaptive clamping of the copper tube. At the same time, the preload provided by the spring ensures that the clamping force is stable and reliable.

[0013] Furthermore, the synchronization component includes a first synchronization rack and a second synchronization rack. The first synchronization rack is installed on the side wall of the first longitudinal clamping component, and the second synchronization rack is installed on the side wall of the second longitudinal clamping component. The first longitudinal clamping component is equipped with synchronization gears via a connecting arm, and the synchronization gears are meshed with the first synchronization rack and the second synchronization rack.

[0014] The beneficial effects of adopting the above-mentioned further solution are: through the meshing transmission of the first synchronous rack, the second synchronous rack and the synchronous gear, it is beneficial to make the first longitudinal clamping component and the second longitudinal clamping component move synchronously in opposite directions, ensuring that the clamping force of the clamping wheels on both sides of the copper tube is balanced and symmetrical, avoiding the copper tube from being deviated due to uneven force, and improving the clamping and positioning accuracy.

[0015] Furthermore, the lateral clamping assembly includes a first lateral rotating shaft and a second lateral rotating shaft, and a rotating sleeve is provided over the first lateral rotating shaft and the second lateral rotating shaft; The first lateral rotation axis and the second lateral rotation axis are mounted on the lateral synchronization assembly.

[0016] The beneficial effects of adopting the above-mentioned further scheme are: the first and second transverse rotation shafts cooperate with the rotating sleeve to provide rolling support from the side of the copper tube, which not only restricts the transverse displacement of the copper tube, but also reduces the resistance of the copper tube during rotational feeding through rolling friction. At the same time, the transverse synchronization component ensures the synchronicity of the transverse clamping on both sides, so that the copper tube maintains a stable posture during the cutting process.

[0017] Furthermore, the lateral synchronization component includes a first lateral rack and a second lateral rack arranged opposite to each other, the first lateral rack and the second lateral rack being engaged with the fixing block by a dovetail groove; A transverse synchronous gear is mounted on the frame, and the transverse synchronous gear meshes with a first transverse rack and a second transverse rack.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that the meshing transmission between the transverse synchronous gear and the transverse racks on both sides ensures that the first transverse rotating shaft and the second transverse rotating shaft move closer or further away synchronously, thereby realizing the self-centering clamping of the copper tube.

[0019] Furthermore, the sidewall of the first or second transverse rack is connected to the baffle via an elastic connector.

[0020] The beneficial effects of adopting the above-mentioned further solution are: the elastic connector provides flexible buffer for lateral clamping, so that the lateral clamping force can be automatically adjusted according to the shape of the copper tube, avoiding deformation or surface damage of the copper tube caused by rigid clamping.

[0021] Furthermore, the high-frequency vibration component includes an ultrasonic generator, the output end of which is connected to a transducer and a contact member, the contact member being arc-shaped and used to contact the copper tube. The ultrasonic generator is mounted on the frame via a telescopic device.

[0022] The beneficial effects of adopting the above-mentioned further solution are as follows: the ultrasonic generator converts high-frequency electrical energy into mechanical vibration through a transducer, which is then transmitted to the copper tube via an arc-shaped contact piece. This high-frequency vibration makes the separation process of the molten metal more thorough, reducing the re-solidification of slag at the copper tube end. The high-frequency vibration also helps to remove slag in a timely manner, reducing the obstruction of the electric arc and heat conduction caused by slag accumulation, thus making energy utilization more efficient. High-frequency vibration can not only reduce the width of the heat-affected zone, but also reduce residual thermal stress, reduce the deformation of thin-walled pipes and maintain the original properties of materials. High-frequency vibration can shake off the top molten metal before gravity acts or change its surface tension state, thereby obtaining a more angular and precise top edge. High-frequency vibration allows molten slag to be blown away quickly, reducing slag splashing and adhesion at the cutting tip. This can reduce the risk of the cutting tip being contaminated and clogged, which may indirectly extend the service life of the cutting tip. High-frequency vibration also helps to break the relatively static air layer above the cutting area, promoting the upward diffusion of smoke and dust.

[0023] Furthermore, the rotating assembly includes a large rotating gear with a through cavity in the middle, and the frame is connected to the large rotating gear; The large rotating gear is uniformly meshed with multiple support gears on its outer circumference. The support gears are mounted on the housing, and one of the support gears is also connected to a servo power component.

[0024] The beneficial effects of adopting the above-mentioned further solution are: the servo power component drives the support gear to drive the large rotating gear to rotate precisely, thereby driving the frame and copper tube to rotate at a set angle, which, together with the cutting component, achieves precise contour forming of the irregular port, and multiple support gears mesh evenly to support the large rotating gear, distributing the load and improving rotational stability.

[0025] Furthermore, the cutting assembly includes a plasma cutter, which is installed at the output end of the robot arm.

[0026] The beneficial effects of adopting the above-mentioned further solutions are: using a plasma cutter for non-contact thermal cutting results in fast cutting speed, narrow kerf, and small heat-affected zone. Combined with the multi-degree-of-freedom motion of the robotic arm, it can flexibly achieve precise cutting of various complex irregular-shaped ports. Attached Figure Description

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a heat exchanger copper tube end cutting device includes... The first longitudinal clamping assembly 1 and the second longitudinal clamping assembly 2 are mounted on the frame 3 and are arranged opposite each other for longitudinal centering clamping of the copper tube. A synchronization assembly 4 is installed between the first longitudinal clamping assembly 1 and the second longitudinal clamping assembly 2. The synchronization assembly 4 ensures that the clamping assemblies on both sides move synchronously, avoiding the copper tube from shifting due to unilateral movement and keeping it always concentric. The lateral clamping assembly 5 is mounted on the frame 3 and located on the side walls of the first longitudinal clamping assembly 1 and the second longitudinal clamping assembly 2, forming a three-dimensional clamping structure with the longitudinal clamping assemblies to achieve multi-directional fixation of the copper tube. The high-frequency vibration component 6 is mounted on the frame 3, and the actuator of the high-frequency vibration component 6 is used to abut against the copper tube. The high-frequency vibration component 6 converts high-frequency electrical energy into mechanical vibration and transmits it to the copper tube. The high-frequency vibration improves the cutting conditions. After the copper tube is clamped and fixed, the actuator of the high-frequency vibration component 6 is attached to the outer wall of the copper tube. After starting, it generates high-frequency vibration, which acts on the cutting area, reduces cutting resistance and reduces burrs. The rotating component 7 and the frame 3 are mounted on the rotating component 7. The rotating component 7 drives the frame 3 to rotate at a set speed and angle, thereby driving the copper tube to rotate synchronously, and working with the cutting component to complete the irregular contour forming. Cutting component 8 is mounted on base 9 and is used to cut the ends of copper tubes.

[0034] like Figure 1 , Figure 2As shown, in some embodiments, both the first longitudinal clamping assembly 1 and the second longitudinal clamping assembly 2 include clamping wheels 10. Each clamping wheel 10 has a conical clamping groove 11. Utilizing the self-centering characteristic of the conical surface, it adapts to copper tubes of different diameters, simultaneously achieving the dual functions of radial clamping and axial positioning. The clamping groove 11 has anti-slip textures to increase the friction between the clamping surface and the outer wall of the copper tube, preventing relative slippage. The clamping wheels 10 are mounted on the moving assembly via mounting brackets. One of the clamping wheels 10 also has a feeding servo power assembly 12 mounted on its side wall. A servo motor drives the clamping wheel to rotate, using friction to drive the copper tube axially. Specifically, after the clamping wheel 10 clamps the copper tube, the feeding servo power assembly 12 drives the corresponding clamping wheel 10 to rotate at a constant speed. The friction between the anti-slip texture and the copper tube drives the copper tube to move axially, achieving automatic feeding without manual pushing, thus improving the degree of automation in the processing.

[0035] In this embodiment, the moving component includes a slider 13 mounted on the side wall of the mounting bracket. The frame 3 has a vertical mounting plate, on which a slide rail 14 that cooperates with the slider 13 is mounted. The sliding pair structure enables the smooth movement of the mounting bracket, ensuring no deviation during the movement of the clamping wheel and providing adjustment space for clamping copper pipes of different diameters. A guide sleeve 16 and a guide rod 15 are also installed between the mounting bracket and the frame 3. The guide sleeve and guide rod provide precise guidance for the movement of the mounting bracket and prevent tilting during the movement. A spring 17 is sleeved on the guide sleeve 16 and the guide rod 15. The two ends of the spring 17 abut against the mounting bracket and the frame 3 respectively, using the elastic preload of the spring to provide a stable clamping force while achieving flexible clamping. When clamping copper tubes of different diameters, the mounting bracket moves along the slide rail 14 via the slider 13. The guide sleeve 16 and the guide rod 15 ensure accurate movement direction. The spring 17 is compressed or stretched to generate an adaptive preload, so that the clamping wheel 10 always fits against the outer wall of the copper tube, ensuring a firm clamping while avoiding deformation of the copper tube caused by rigid clamping.

[0036] The synchronization component 4 includes a first synchronization rack 18 and a second synchronization rack 20. The first synchronization rack 18 is mounted on the side wall of the first longitudinal clamping component 1, and the second synchronization rack 20 is mounted on the side wall of the second longitudinal clamping component 2. The first longitudinal clamping component 1 is equipped with a synchronization gear 19 via a connecting arm. The synchronization gear 19 meshes with both the first synchronization rack 18 and the second synchronization rack 20. Through the meshing transmission characteristics of the gears and racks, the movement on one side is transmitted to both sides, realizing the synchronous action of the clamping components on both sides. When the device needs to clamp or release the copper tube, the power mechanism drives the synchronization gear 19 to rotate. The synchronization gear 19 simultaneously drives the first synchronization rack 18 and the second synchronization rack 20 to move in opposite directions, thereby causing the first longitudinal clamping component 1 and the second longitudinal clamping component 2 to move closer or further away synchronously. This ensures that the clamping force on both sides is balanced, avoids the copper tube from shifting due to uneven force, and improves the clamping and positioning accuracy.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, in another embodiment, the lateral clamping assembly 5 includes a first lateral rotating shaft 21 and a second lateral rotating shaft 37. The first lateral rotating shaft 21 and the second lateral rotating shaft 37 are fitted with a rotating sleeve 22. The rotating sleeve converts sliding friction into rolling friction, reducing the resistance when the copper tube rotates, and at the same time avoiding scratching the surface of the copper tube. The first lateral rotating shaft 21 and the second lateral rotating shaft 37 are mounted on a lateral synchronization assembly. The lateral synchronization assembly is used to realize the synchronous movement of the rotating shafts on both sides, ensuring the symmetry of lateral clamping. Specifically, the transverse synchronization component includes a first transverse rack 38 and a second transverse rack 23 arranged opposite to each other. The first transverse rack 38 and the second transverse rack 23 are engaged with the fixed block 24 through a dovetail groove. The dovetail groove provides precise guidance for the movement of the racks and restricts the vertical displacement of the racks to ensure stable meshing transmission. A transverse synchronization gear 25 is installed on the frame 3. The transverse synchronization gear 25 meshes with the first transverse rack 38 and the second transverse rack 23. Through the meshing transmission of the synchronization gear, the racks on both sides move synchronously towards or away from each other, thereby driving the first transverse rotating shaft 21 and the second transverse rotating shaft 37 to move closer or further away synchronously. The sidewall of the first transverse rack 38 or the second transverse rack 23 is connected to the baffle 27 through an elastic connector 26 to provide flexible buffering and avoid deformation of the copper tube caused by rigid clamping. When the lateral clamping is started, the lateral synchronous gear 25 rotates, driving the first lateral rack 38 and the second lateral rack 23 to move synchronously along the dovetail groove, causing the first lateral rotating shaft 21 and the second lateral rotating shaft 37 to approach the copper tube. The rotating sleeve 22 fits against the outer wall of the copper tube, and the elastic connector 26 is adaptively compressed according to the shape of the copper tube to provide flexible clamping force. The baffle 27 serves to limit and install the elastic connector 26.

[0038] like Figure 2 , Figure 3 As shown in the embodiment, the high-frequency vibration component 6 includes an ultrasonic generator 28. The output end of the ultrasonic generator 28 is connected to a transducer and a contact member 29. The contact member 29 is arc-shaped and used to contact the copper tube. The arc-shaped structure of the contact member 29 increases the contact area with the copper tube, ensuring stable vibration transmission and preventing excessive local force from damaging the copper tube. The ultrasonic generator 28 is mounted on the frame 3 via a telescopic device 30. Adjusting the fit between the contact member 29 and the copper tube ensures effective vibration transmission. After the copper tube is clamped, the telescopic device 30 pushes the ultrasonic generator 28 to move, causing the contact member 29 to fit tightly against the outer wall of the copper tube. The ultrasonic generator 28 starts, converting high-frequency electrical energy into high-frequency mechanical vibration through the transducer, which is then transmitted to the copper tube cutting area via the contact member 29. The high-frequency vibration makes the molten metal in the cutting area separate more thoroughly, reducing slag adhesion, while also reducing cutting resistance and improving cut quality.

[0039] like Figure 2 and Figure 3 As shown, in this embodiment, the rotating component 7 includes a large rotating gear 31. The large rotating gear 31 has a through cavity 32 in the middle, which provides space for the copper tube to pass through, avoiding interference between the component and the copper tube during rotation. The frame 3 is connected to the large rotating gear 31. Through the fixed connection, the rotation of the large rotating gear 31 is synchronously transmitted to the frame 3, thereby driving the copper tube to rotate. Multiple support gears 33 are evenly meshed around the outer circumference of the large rotating gear 31. The multiple support gears 33 evenly distribute the load of the large rotating gear 31, improve rotational stability, and avoid shaking caused by single gear support. The support gears 33 are mounted on the housing 35, and the housing 35 provides fixed support for the support gears 33 to ensure stable transmission. One of the support gears 33 is also connected to a servo power component 34. The servo power component 34 is electrically connected to the control component (not output in the figure), and provides precise rotational power through the servo motor to achieve precise control of speed and angle. During the actual cutting operation, the servo power component 34 is activated, driving the connected support gear 33 to rotate. The support gear 33 drives the rotating large gear 31 to rotate at a constant speed. The rotating large gear 31 drives the frame 3 and the clamped copper tube to rotate synchronously. The rotation speed and angle are precisely controlled by the servo system, which works in conjunction with the cutting components to complete the continuous forming of irregularly shaped ports.

[0040] The cutting assembly 8 includes a plasma cutter 36, which uses the high temperature of the plasma arc to melt the metal at the end of the copper tube to achieve non-contact cutting. It has the advantages of fast cutting speed, narrow kerf and small heat-affected zone. The plasma cutter 36 is installed at the output end of the robot arm, which provides multi-degree-of-freedom motion to adapt to the cutting trajectory of irregularly shaped ports with different degrees of complexity.

[0041] During the rotation of the copper tube, the robot arm drives the plasma cutter 36 to move according to the preset trajectory of the irregular port. The plasma cutter 36 starts to generate a plasma arc, which melts the metal at the end of the copper tube at high temperature, completing the cutting of the irregular port. At the same time, the high-frequency vibration component 6 can reduce slag accumulation and improve the surface finish and dimensional accuracy of the cut.

[0042] In other embodiments, a low-current, low-frequency (DC or AC near power frequency) current is additionally supplied to the copper tube via the clamping wheel 10, forming an electromagnetic force-assisted cutting structure. The Lorentz force generated by the current flowing through the molten pool area of ​​the copper tube cut actively intervenes in the processing, synergizing with ultrasonic vibration. First, the molten pool is directionally driven, strongly assisting in slag removal. Ultrasonic vibration loosens the slag, and the electromagnetic force can directionally discharge the slag, especially suitable for sticky slag, achieving near-slag-free cutting. Second, the magnetic compression effect stabilizes the plasma arc, making the arc more concentrated and the energy density higher, resulting in a narrower kerf and a smaller heat-affected zone. Furthermore, it improves energy utilization efficiency, reduces energy loss, and can increase cutting speed or improve the cutting ability of thick plates at the same power.
