It reduces the diameter of the end or specific part of the tube by applying radial force to achieve the desired shape and size. It is usually composed of a mold, a clamping mechanism, a power system and a control system. It is widely used in industries such as automobiles, aerospace, construction and home appliances.

[0027] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] Existing tube shrinking machines usually adopt a single-head processing mode, that is, only one end of the tube can be shrunk at a time. If both ends of the tube need to be processed, the position of the tube needs to be manually adjusted or the mold needs to be replaced, which leads to low processing efficiency. In fields such as automotive air-conditioning tubes that require high-precision and large-scale processing, the single-head processing mode is difficult to meet the needs of modern manufacturing for efficient production, and the tubes are prone to displacement or deformation when the position is manually adjusted, which makes it difficult to ensure the processing accuracy, affects the quality of the tube shrinkage, and even causes an increase in the scrap rate. In order to solve these problems, the present application proposes a copper tube automatic transposition and continuous tube shrinking device, which realizes efficient and precise operation of the copper tube in transposition and continuous tube shrinking processing through the coordinated work of a feeding mechanism, a tube shrinking mechanism, a grinding mechanism, a reversing mechanism and a control terminal.

[0030] See also Figure 1-Figure 6 The invention discloses an automatic position-changing and continuous shrinking device for copper tubes, comprising a feeding mechanism, a shrinking mechanism 1, a grinding mechanism 2, a reversing mechanism 3 and a control terminal. The feeding mechanism is used to transport the copper tube to the shrinking mechanism 1, the shrinking mechanism 1 is used to clamp and rotate the copper tube, the grinding mechanism 2 is connected to the control terminal for communication, and processes the end of the copper tube according to the instruction of the control terminal. The shrinking mechanism 1 is provided with a tube pushing assembly 5, the tube pushing assembly 5 is used to push the copper tube to the reversing mechanism 3, the reversing mechanism 3 is used to adjust the position of the copper tube, the reversing mechanism 3 is provided with a visual detection unit, the visual detection unit is connected to the control terminal for communication, and the visual detection unit is used to obtain the center line information of the copper tube.

[0031] The visual inspection unit is usually composed of a camera or an image sensor. First, the image of the copper tube needs to be collected in real time. These cameras can use different light sources (such as white light, infrared light, etc.) to ensure that clear images can be obtained even under different lighting conditions; the collected images will be transmitted to the processing unit, and the image will be analyzed using image processing software. This step may include image denoising, contrast enhancement, edge detection, etc., in order to extract the contour information of the copper tube; through image processing technology, the system will identify the edge of the copper tube, and usually use edge detection algorithms (such as Canny edge detection) to find the boundary of the tube. Then, the center line of the tube is determined by a circular or elliptical fitting algorithm; after identifying the tube contour, the system will further calculate the geometric center or best fit line of the contour, which represents the center line of the copper tube. This calculation process may involve geometric operations and coordinate transformations to ensure the accuracy of the center line; the processed center line data will be sent to the control terminal to guide subsequent processing or adjustment. These instructions can ensure that the tube shrinking mechanism 1 or the reversing mechanism 3 can be adjusted in real time according to the actual position and direction to achieve precise processing. Through the above steps, the visual inspection unit can effectively obtain the centerline information of the copper tube, realize accurate control of the processing process, and ensure that the size and shape of the final product meet the requirements. This automated measurement and adjustment greatly improves production efficiency and product quality.

[0032] The automatic transposition and continuous shrinking device for copper tubes solves the problems of low efficiency and poor precision in the transposition and continuous shrinking of copper tubes in the prior art through the coordinated work of the feeding mechanism, the shrinking mechanism 1, the grinding mechanism 2, the reversing mechanism 3 and the control terminal. The feeding mechanism transports the copper tube to the shrinking mechanism 1, the shrinking mechanism 1 clamps and rotates the copper tube, the grinding mechanism 2 grinds the end of the copper tube under the command of the control terminal, the pushing assembly 5 pushes the copper tube to the reversing mechanism 3, the reversing mechanism 3 adjusts the position of the copper tube, and the visual inspection unit obtains the center line information of the copper tube and feeds it back to the control terminal. In this way, efficient and precise operation of the copper tube in transposition and continuous shrinking is achieved.

[0033] Compared with the prior art, the automatic transposition and continuous shrinking device for copper tubes has significant advantages. Through the coordinated work of the feeding mechanism, the shrinking mechanism 1, the grinding mechanism 2, the reversing mechanism 3 and the control terminal, the automatic transposition and continuous shrinking processing of the copper tubes are realized, the processing efficiency and accuracy are improved, the offset and deformation problems caused by manual position adjustment are avoided, and the demand for efficient production in modern manufacturing is met.

[0034] In order to provide uniform clamping force and avoid displacement and deformation of the copper tube, based on this, in one embodiment, the tube shrinking mechanism 1 includes a die sleeve assembly 11 and a driving assembly 12. The die sleeve assembly 11 includes a frame 111, a tube body 112, a clamp 113 and a push rod 114. The tube body 112 is arranged on the frame 111, and the clamp 113 is arranged at the end of the tube body 112 for fixing the copper tube. The clamp 113 is composed of a plurality of groups of tightly-fitting embracing mold bodies. The push rod 114 is arranged in the tube body 112 for abutting against the clamp 113. The driving assembly 12 includes a driving motor 121 and a pulley 122. The driving motor 121 is used to drive the pulley 122 to rotate, and the pulley 122 is used to drive the tube body 112 to rotate. The frame 111, the tube body 112, the clamp 113 and the push rod 114 in the die sleeve assembly 11 work together to ensure that the copper tube can be firmly fixed during the tube shrinking process. The clamping member 113 is composed of several groups of tightly fitting embracing mold bodies. This design can provide uniform clamping force to prevent the copper tube from being displaced or deformed during processing. The push rod 114 abuts against the clamping member 113, further enhancing the fixing effect. The driving motor 121 and the pulley 122 in the driving assembly 12 realize the stable rotation of the copper tube by rotating the tube body 112.

[0035] The design of the clamping member 113 can be implemented in a variety of ways. For example, a high-strength alloy material can be used to manufacture an embracing mold body to ensure that the shape and function can be maintained under high compression force. The push rod 114 can be hydraulically driven to provide greater thrust and more precise control. The present application effectively solves the problem of loose fixation and unstable rotation of the copper tube in the shrinking process in the prior art by adopting a combined design of the mold sleeve assembly 11 and the drive assembly 12. By using a close-fitting embracing mold body, a uniform clamping force is provided to avoid the displacement and deformation of the copper tube. The setting of the push rod 114 further enhances the fixing effect, and the coordinated use of the drive motor 121 and the pulley 122 realizes the stable rotation of the copper tube. Compared with the prior art, the present application not only improves the efficiency and stability of the shrinking process, but also ensures the processing accuracy and reduces the scrap rate.

[0036] In order to save time for replacing the chuck 115, reduce maintenance costs and difficulty, and ensure long-term stable operation of the equipment, based on this, in one embodiment, the mold sleeve assembly 11 also includes a chuck 115, a dovetail groove 116 is provided on the clamping member 113, and the dovetail groove 116 is provided along the axial direction of the copper tube. A limiter 117 is provided on the chuck 115, and the limiter 117 is plugged and matched with the dovetail groove 116. By providing the dovetail groove 116 on the clamping member 113 and the limiter 117 on the chuck 115, the limiter 117 can be plugged and matched with the dovetail groove 116, ensuring that the copper tube remains stable during the shrinking process and avoiding positional deviation; the dovetail groove 116 is formed into a specific shape on the clamping member 113, and cooperates with the limiter 117 on the chuck 115. This structure allows the copper tube to remain stable during the shrinking process and avoids positional deviation caused by mechanical reaction during the processing. Since the dovetail groove 116 can provide a larger contact area and better mechanical locking, the chuck 115 can firmly fix the pipe in the clamped state, reduce vibration and movement, and thus ensure processing accuracy; the design of the dovetail groove 116 makes the installation and removal of the chuck 115 easier and faster. When it is necessary to replace the chuck 115 of different specifications (for example, for copper tubes of different diameters or thicknesses), the worker only needs to pull out the limiter 117 from the dovetail groove 116 and reinsert the appropriate new chuck 115. This greatly saves the time of replacing the chuck 115 and improves production efficiency; the flexibility of the design of the dovetail groove 116 allows it to adapt to copper tubes of various specifications. By adjusting the position information of the chuck 115, the clamping requirements of different pipes can be better met, which is particularly important for small-batch production of multiple varieties. The length and angle of the dovetail groove 116 can also be customized according to actual production needs, providing greater design freedom; the combined structure of the dovetail groove 116 and the chuck 115 is relatively simple, making the maintenance of the equipment more convenient. When wear or damage occurs, the chuck 115 can be quickly disassembled for inspection or replacement, which can be easily completed by non-professionals, thereby reducing maintenance costs and difficulty and ensuring the long-term stable operation of the equipment.

[0037] In order to achieve accurate processing at different angles during the processing, so that the same equipment can adapt to a variety of processing techniques and requirements, based on this, in one embodiment, the tube shrinking mechanism 1 is also provided with a direction adjustment component 6, which includes a clamping seat 61 and a steering motor 62, the clamping seat 61 is fixed to the tube body 112, and the steering motor 62 is used to drive the clamping seat 61 to rotate. The core function of the direction adjustment component 6 is to be able to easily adjust the direction of the copper tube. This design allows the operator to flexibly adjust the positioning of the pipe according to specific processing requirements to ensure that it can be accurately processed at different angles during the processing; by driving the rotation of the clamping seat 61 by the steering motor 62, the copper tube can be fine-tuned before and after processing to adapt to the requirements of the tool or other processing equipment, thereby significantly improving the positioning accuracy of the processing and reducing the dimensional error caused by the direction deviation; the automated direction adjustment function can greatly reduce the need for manual operation, and the worker does not need to frequently manually adjust the position of the copper tube. This automated adjustment reduces the downtime during the processing and improves the overall production efficiency; the setting of the direction adjustment component 6 enables the same equipment to adapt to a variety of processing techniques and requirements. For example, different tube shrinking processes may require different angle settings for the tube, and the direction adjustment component 6 can quickly adapt to these changes to ensure the consistency and efficiency of the processing.

[0038] In order to achieve accurate adjustment of the position of the grinding mechanism 2 during the processing of the copper tube end and reduce the error of manual adjustment, based on this, in one embodiment, the grinding mechanism 2 includes a base 21, a screw assembly 22, a mounting seat 23 and a grinding wheel 24, the screw assembly 22 is arranged on the base 21, the screw assembly 22 is driven by a motor, the mounting seat 23 is threadedly mounted with the screw assembly 22, and the grinding wheel 24 is rotatably mounted on the mounting seat 23. The base 21 of the grinding mechanism 2 provides a stable installation foundation, the screw assembly 22 can achieve accurate linear motion through the motor drive, the mounting seat 23 is threadedly connected with the screw assembly 22 to ensure accurate adjustment of the grinding position, and the rotatable installation of the grinding wheel 24 enables it to effectively grind the copper tube end. Through the mutual cooperation of these technical features, the problem of position adjustment of the grinding mechanism 2 during the processing of the copper tube end is solved, and the grinding process is efficient and accurate; the screw assembly 22 can achieve accurate linear motion through motor drive, the mounting seat 23 is threadedly connected to the screw assembly 22 to ensure the accurate adjustment of the grinding position, and the rotating installation of the grinding wheel 24 enables it to effectively grind the copper tube end. The screw assembly 22 can adopt a ball screw or a trapezoidal screw, the motor can adopt a stepping motor or a servo motor, the mounting seat 23 can be made of aluminum alloy or steel, and the grinding wheel 24 can be selected from different materials according to different grinding requirements, such as an alumina grinding wheel 24 or a silicon carbide grinding wheel 24; the present application realizes the accurate adjustment of the position of the grinding mechanism 2 during the processing of the copper tube end by setting a base 21, a screw assembly 22, a mounting seat 23 and a grinding wheel 24, and solves the problem of inconvenient grinding position adjustment in the prior art. Compared with the prior art, the grinding mechanism 2 provided by the present application can effectively improve the efficiency and accuracy of grinding, reduce the error of manual adjustment, and ensure the processing quality.

[0039] In order to accurately adjust the rotation of the screw assembly 22 and realize the accurate adjustment of the position of the grinding wheel 24, based on this, in one embodiment, a displacement detection unit is provided in the tube body 112, and the displacement detection unit is connected to the control terminal in communication. The displacement detection unit is used to detect the displacement of the copper tube in the tube body 112, and feed back the detected data to the control terminal. The control terminal performs position accuracy compensation calculation according to the fed-back displacement data, and instructs the rotation of the screw assembly 22 according to the accuracy compensation information to realize the position adjustment of the grinding wheel 24. By setting the displacement detection unit, the displacement of the copper tube in the tube body 112 can be detected in real time, and the detection data can be fed back to the control terminal in time. The control terminal performs position accuracy compensation calculation according to these displacement data, so that the rotation of the screw assembly 22 can be accurately adjusted to realize the accurate adjustment of the position of the grinding wheel 24. In this way, the problem of displacement detection and position accuracy compensation of the copper tube in the tube body 112 can be effectively solved, and the processing accuracy can be ensured while improving the processing quality; the displacement detection unit can be implemented in a variety of ways, for example, a photoelectric sensor, a laser rangefinder or an inductive sensor can be used to realize displacement detection. Specifically, the photoelectric sensor detects displacement changes by emitting and receiving light beams, the laser rangefinder calculates displacement by measuring the laser reflection time, and the inductive sensor determines displacement by detecting changes in electromagnetic induction. These implementation methods each have their own advantages and disadvantages, and the appropriate method can be selected according to specific application requirements; therefore, the present application sets a displacement detection unit in the tube body 112 and communicates with the control terminal to enable real-time monitoring of the displacement of the copper tube and accurate displacement compensation calculation. This technical solution can not only effectively solve the problems of displacement detection and position accuracy compensation of copper tubes in the prior art during processing, but also improve the processing accuracy and quality, reduce the scrap rate, and improve production efficiency.

[0040] In order to realize the real-time monitoring and early warning function of the temperature at the end of the copper tube and ensure the safety of the processing process and the product quality, based on this, in one embodiment, a temperature detection unit is also provided on the mounting seat 23, and the temperature detection unit is connected to the control terminal in communication. The temperature detection unit is used to detect the temperature at the end of the copper tube. The temperature detection unit feeds back the detected temperature information to the control terminal. When the temperature exceeds the preset temperature, the control terminal issues an alarm. The temperature detection unit is used to detect the temperature at the end of the copper tube in real time and transmit the detected temperature data to the control terminal. The control terminal analyzes the temperature data. When it is detected that the temperature exceeds the preset safety threshold, the control terminal will issue an alarm to remind the operator to take necessary cooling measures or suspend the operation. This technical feature effectively solves the problem of excessive temperature that may occur in the copper tube during the processing process through temperature monitoring and alarm mechanisms, and ensures the safety of the processing process and product quality; the temperature detection unit can use a thermocouple, an infrared temperature sensor or other temperature sensors suitable for high temperature environments. The thermocouple can be directly installed at the end of the copper tube to transmit temperature data through electrical signals; the infrared temperature sensor can measure the temperature non-contactly, avoiding the wear and pollution that may be caused by direct contact between the sensor and the copper tube. The control terminal can set multiple levels of temperature control thresholds, such as 200°C for the first-level warning, 250°C for the second-level speed reduction, and 300°C for the third-level shutdown, so as to take different countermeasures in different temperature ranges. The control terminal can remind the operator through a display screen, a sound alarm, or an online notification; the present application realizes the real-time monitoring and early warning function of the end temperature of the copper tube by setting a temperature detection unit on the mounting seat 23 and communicating with the control terminal. Compared with the prior art, the present application can issue an alarm in time when the temperature of the copper tube is too high, reminding the operator to take cooling or shutdown measures, avoiding processing quality problems and equipment damage caused by excessive temperature, and improving the safety and stability of the processing process.

[0041] In order to ensure that the copper tube is always in the correct position during the processing and reduce the processing error caused by the offset, based on this, in one embodiment, a chute 7 is provided in the tube body 112, and a sliding block 4 is provided at the end of the push rod 114. The outer peripheral surface of the sliding block 4 slides along the chute 7, and the inner peripheral surface of the sliding block 4 abuts against the clamping member 113. The setting of the chute 7 realizes the smooth sliding of the push rod 114 in the tube body 112, so that the push rod 114 can move freely along the set trajectory. This design allows the operator or the control system to accurately adjust the displacement of the push rod 114 as needed, thereby adjusting the clamping force of the clamping member 113 on the copper tube, and realizing more precise control; the clamping force required for copper tubes of different specifications or materials during the processing will also be different. By adjusting the displacement of the push rod 114, it can be ensured that the clamping force matches the characteristics of the tube, thereby avoiding deformation caused by tube sliding due to insufficient clamping or excessive clamping; in the process of shrinking the tube, especially in high-speed processing, the copper tube may be displaced due to the action of the processing force in the clamping state. The design of the chute 7 enables the push rod 114 to stably abut against the clamping member 113, thereby effectively resisting any possible displacement. This ensures that the copper tube always remains in the correct position during the processing, reducing the processing error caused by offset; when the chute 7 is used in conjunction with the position detection unit, the system can monitor the position and clamping state of the push rod 114 in real time. The position detection unit can feedback the current position of the push rod 114 to ensure that the clamping member 113 is exactly in the required clamping position.

[0042] In order to reduce the thermal impact of the material and ensure the grinding quality, the copper tube will generate heat during the grinding process. Excessive temperature may cause deformation of the material or aggravation of the grinding wheel 24. Based on this, in one embodiment, the control terminal adjusts the rotation speed of the grinding wheel 24 according to the data obtained by the temperature detection unit and the preset tube shrinking instruction. By monitoring the temperature data through the temperature detection unit, the control system can adjust the rotation speed of the grinding wheel 24 in real time to avoid overheating, thereby effectively reducing the thermal impact of the material and ensuring the grinding quality; reasonable speed adjustment can prevent the grinding wheel 24 from wearing out quickly at too high a speed, extend the service life of the grinding wheel 24, reduce the replacement frequency, and thus reduce production costs; adjusting the rotation speed of the grinding wheel 24 can effectively prevent the grinding wheel 24 from overloading during operation, thereby reducing the risk of equipment failure. For example, if the rotation speed of the grinding wheel 24 is too fast, it may cause the grinding wheel 24 to break or damage the pipe. This risk can be reduced by real-time monitoring and adjustment; by dynamically adjusting the rotation speed of the grinding wheel 24 following the temperature change, the safety of the operation process can be ensured, and safety hazards caused by equipment abnormality or material loss of control can be avoided.

[0043] In order to change the orientation of the copper tube according to processing needs and enhance the flexibility of the production line, based on this, in one embodiment, the reversing mechanism 3 includes a mounting frame 31, a cylinder 32, a support plate 33, a steering groove 34 and a push rod 35. The cylinder 32 is arranged on the mounting frame 31, the support plate 33 is arranged on the telescopic end of the cylinder 32, the steering groove 34 is rotatably mounted on the support plate 33, and the push rod 35 is slidably mounted on the support plate 33. The push rod 35 is used to push the copper tube into the clamping member 113. The cylinder 32 is installed on the fixed mounting frame 31, which is the main power source of the reversing mechanism 3. Under the command of the control system, the air pressure change in the cylinder 32 causes the cylinder 32 to expand and contract, generating linear motion; as the cylinder 32 expands and contracts, its telescopic end is connected to the support plate 33, and the movement of the cylinder 32 will push the support plate 33 to move. When the cylinder 32 extends outward, the support plate 33 also moves accordingly, thereby achieving support and adjustment of the steering groove 34; the steering groove 34 is rotatably mounted on the support plate 33, and through the action of the cylinder 32, the movement of the support plate 33 enables the steering groove 34 to change its angle. This rotation allows the copper tube to enter the subsequent clamping mechanism in different directions to meet different processing requirements; the push rod 35 is slidably mounted on the support plate 33, usually based on the action of the cylinder 32. After the support plate 33 moves to the set position, the push rod 35 is designed to slide and push the copper tube forward. By controlling the movement of the push rod 35, the copper tube can be smoothly pushed out and accurately sent into the interior of the clamp 113, ready for the next step of processing.
