Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, and in particular to a pipe necking processing system and method. Background Technology

[0002] In the process of pipe processing, in order to meet the process requirements, it is often necessary to reduce the diameter of the pipe material, such as copper pipe, so that the copper pipe reaches the outer diameter required by the process.

[0003] In related technologies, most pipe shrinking processing systems have low automation levels, requiring operators to manually insert the pipe into the shrinking machine. This processing method is time-consuming, labor-intensive, and inefficient. In some automatic pipe shrinking processing systems, the workpiece cannot be accurately pushed into the shrinker in a straight line, resulting in poor accuracy and stability, frequent failures, and affecting processing efficiency and quality, which is not conducive to automated continuous operation.

[0004] Therefore, how to improve the processing accuracy and efficiency of pipe shrinking processing systems is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a pipe necking processing system and method, which can effectively improve the efficiency and dimensional accuracy of pipe necking processing and increase the pass rate.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A pipe shrinking processing system and method includes: a shrinking machine having a shrinking processing cavity for inserting and shrinking pipes, the shrinking processing cavity extending along a first direction; a clamping mechanism having a clamping cavity extending along the first direction and clamping the pipes along a second direction, the first direction being perpendicular to the second direction; the clamping cavity includes a first cavity and a second cavity arranged sequentially along the first direction, the first cavity being located near the shrinking machine, and the pipes being placed in the first cavity; a correction and propulsion mechanism for pushing the clamping mechanism to move so as to drive the pipes into the shrinking processing cavity; the correction and propulsion mechanism includes a correction limiting component with an adjustable tilt angle, the correction limiting component being adapted to the size of the second cavity, and the correction limiting component being able to be inserted into the second cavity to adjust the tilt angle of the second cavity.

[0008] The present invention also provides a pipe necking process, comprising the following steps: determining the initial advancing distance L1 of the pipe based on the initial pipe diameter R0, the target pipe diameter r, and the position of the clamping mechanism; pushing the pipe into the necking machine for necking processing based on the initial advancing distance L1, and detecting the actual pipe diameter R of the processed pipe; determining the next advancing distance L of the pipe based on the actual pipe diameter R, the target pipe diameter r, and the processing inclination angle α of the necking processing cavity; L = L1 + L2, L2 = (R / tanα) - (r / tanα); pushing the pipe into the necking machine for necking processing based on the advancing distance L.

[0009] The pipe shrinking processing system provided by this invention has the following advantages: The pipe is fixed by a clamping mechanism, and power is provided by a correction and propulsion mechanism to move the clamping mechanism. The clamping mechanism drives the pipe to move, thereby inserting the pipe into the shrinking processing cavity of the shrinking machine, which is used to shrink the pipe. When the pipe and the shrinking processing cavity are not coaxial, the pipe diameter after shrinking is uneven. This application provides a clamping cavity within the clamping mechanism, comprising a first cavity and a second cavity arranged sequentially along a first direction. The first cavity clamps the pipe, while the second cavity serves a fine-tuning function. By inserting a correction and limiting component into the second cavity, when the tilt angle of the correction and limiting component changes, a slight change in the tilt angle of the extension direction of the second cavity occurs, thereby... This causes a slight change in the tilt angle of the first cavity's extension direction, thereby altering the pipe's tilt angle. This design allows for the correction of the pipe's tilt angle, ensuring its levelness and improving processing quality. Specifically, the pipe can be manually placed into the clamping mechanism, and then the correction and propulsion mechanism can be driven to allow the pipe to enter the shrinking processing cavity of the shrinking machine for processing. After processing, the pipe can be removed, and its shrinking processing status can be observed to determine if there is a deviation in the pipe's tilt angle. The corresponding correction limiting component can then be adjusted. The size of the second cavity should be compatible with the size of the correction limiting component. Since the pipe's tilt angle is fine-tuned, the second cavity should also be clamped along the second direction to ensure that it can swing with the correction limiting component.

[0010] The pipe shrinking processing system provided by this invention can adjust the tilt angle of the pipe, ensure the coaxiality of the pipe and the shrinking processing cavity, thereby improving the processing quality of the pipe, increasing the pass rate, and reducing the cost of pipe shrinking processing.

[0011] In one embodiment, the correction and adjustment component includes an up-and-down adjustment component, which includes an up-and-down adjustment support base and a first adjustment member and a second adjustment member arranged sequentially along a first direction. The correction limiting component is mounted on the up-and-down adjustment support base via the first and second adjustment members, and the positions of the first and second adjustment members and the up-and-down adjustment support base are adjustable to change the up-and-down tilt angle of the correction limiting post. This configuration, by adjusting the up-and-down tilt angle of the correction limiting component using the up-and-down adjustment component, thereby changing the up-and-down tilt angle of the pipe; and by changing the position of the first and second adjustment members and the up-and-down adjustment support base, changing the tilt angle of the correction limiting component in the front-and-back direction, thereby changing the up-and-down tilt angle of the pipe; it is convenient to operate and has high position adjustment accuracy.

[0012] In one embodiment, the correction and adjustment component further includes a left-right adjustment component. The left-right adjustment component includes a left-right adjustment support base and a third and fourth adjustment member arranged sequentially along a second direction. The left-right adjustment support base and the upper-lower adjustment support base are arranged sequentially along a first direction, and the third and fourth adjustment members pass through the left-right adjustment support base and connect to the upper-lower adjustment support base. The positions of the third and fourth adjustment members and the upper-lower adjustment support base are adjustable to change the left-right tilt angle of the correction limiting post. This configuration, through the left-right adjustment component, enables adjustment of the left-right tilt angle of the correction limiting component. Specifically, the left-right adjustment support base provides stability, and the third and fourth adjustment members are both mounted on the left-right adjustment support base. By changing the swing angle of the upper-lower adjustment support base, the third and fourth adjustment members change the swing angle of the correction limiting component located on the upper-lower adjustment support base, thereby changing the left-right tilt angle of the pipe. Through the arrangement of the first, second, third, and fourth adjustment members, adjustment of the pipe at any tilt angle can be achieved, ensuring that the pipe is coaxial with the narrowing processing cavity and improving the processing accuracy of the pipe.

[0013] In one embodiment, the system further includes: an image acquisition component for acquiring the pipe diameter; a transport mechanism for acquiring the pipe and controlling its movement; and a controller, to which the clamping mechanism, image acquisition component, and correction and propulsion mechanism are all connected. The controller determines the propulsion distance of the correction and propulsion mechanism based on the pipe diameter and controls its operation based on the propulsion distance. This configuration, by using the image acquisition component to photograph the end face of the pipe after each processing step, allows for the determination of whether the processed pipe is qualified, facilitating subsequent material distribution. Simultaneously, acquiring the pipe diameter after processing provides a basis for correction in subsequent processing, improving the accuracy of subsequent pipe processing and preventing batch processing anomalies. The transport mechanism enables automatic pipe movement, increasing automation and reducing worker workload. The controller enables automatic adjustment and control, improving the accuracy of the propulsion distance determination.

[0014] The pipe necking processing method provided by the present invention includes the following steps: determining the initial advancing distance L1 of the pipe based on the initial pipe diameter R0, the target pipe diameter r, and the position of the clamping mechanism; pushing the pipe into the necking machine for necking processing based on the initial advancing distance L1, and detecting the actual pipe diameter R of the processed pipe; determining the next advancing distance L of the pipe based on the actual pipe diameter R, the target pipe diameter r, and the processing inclination angle α of the necking processing cavity; L = L1 + L2, L2 = (R / tanα) - (r / tanα); pushing the pipe into the necking machine for necking processing based on the advancing distance L. The pipe necking processing method provided by this invention involves correcting the advancing distance L1 of the advancing mechanism during the first pipe necking process. After completing the processing of the first pipe, a photograph is taken to obtain the actual pipe diameter R. Since the necking angle of the necking machine is α, the advancing distance L = L1 + L2 for the next step is calculated. L1 is the template standard value used to correct the advancing mechanism during the first necking process, and L2 = (R / tanα) - (r / tanα). L2 serves as the visual compensation value after each photograph and is used as the basis for correcting the advancing distance of the next pipe. The advancing distance L is adjusted in real time to ensure the processing quality of subsequent pipes and reduce the defect rate. Attached Figure Description

[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Please refer to Figures 1 to 5 In this embodiment, the pipe shrinking processing system includes a shrinking machine 2, a clamping mechanism 3, and a correction and propulsion mechanism 4.

[0033] The shrinking machine 2 is provided with a shrinking processing cavity 21 for inserting the pipe 100 and performing shrinking processing. The shrinking processing cavity 21 extends along the first direction.

[0034] The clamping mechanism 3 has a clamping cavity 31 inside. The clamping cavity 31 extends along a first direction and clamps the pipe 100 along a second direction. The first direction is perpendicular to the second direction. The clamping cavity 31 includes a first cavity 311 and a second cavity 312 arranged sequentially along the first direction. The first cavity 311 is located near the shrinking machine 2, and the pipe 100 is placed in the first cavity 311. Specifically, the clamping mechanism 3 includes a clamping power component and a clamping block. The clamping cavity 31 is located inside the clamping block. The clamping block consists of two separable clamping blocks that can clamp the pipe 100 and the correction and limiting component 41. The clamping power component drives the clamping block to move, thereby realizing clamping and release.

[0035] The correction and propulsion mechanism 4 is used to push the clamping mechanism 3 to move so that the pipe 100 is inserted into the narrowing processing cavity 21. The correction and propulsion mechanism 4 includes a correction limiting component 41 with an adjustable tilt angle. The correction limiting component 41 is adapted to the size of the second cavity 312 and can be inserted into the second cavity 312 to adjust the tilt angle of the second cavity 312.

[0036] Furthermore, it also includes a support body 1, which serves as the support structure for the entire device and can be made of a metal frame; a clamping mechanism 3 is movably mounted on the support body 1; and a correction and propulsion mechanism 4 is movably mounted on the support body 1.

[0037] Specifically, the correction and propulsion mechanism 4 serves both a propulsion function and a correction function, which is a mechanical correction. When processing the first pipe 100, the pipe 100 can be manually placed into the clamping mechanism 3, and then the correction and propulsion mechanism 4 can be driven to allow the pipe 100 to enter the shrinking processing cavity 21 of the shrinking machine 2 for processing. Then, the pipe 100 can be taken out, and the shrinking processing status of the pipe 100 can be observed to determine whether there is a deviation in the inclination angle of the pipe 100. Then, the corresponding correction limit component 41 can be adjusted. When changing different batches of pipe 100, a correction should be performed once, or if there is a deviation in processing accuracy, it can also be re-corrected.

[0038] The pipe shrinking processing system provided by this invention uses a clamping mechanism 3 to fix the pipe 100. Power is provided by a correction and propulsion mechanism 4 to move the clamping mechanism 3, which in turn moves the pipe 100, thus inserting the pipe 100 into the shrinking processing cavity 21 of the shrinking machine 2. The shrinking machine 2 is used to shrink the pipe 100. When the pipe 100 and the shrinking processing cavity 21 are not coaxial, the pipe diameter of the pipe 100 after shrinking is uneven. This application addresses this by providing a clamping cavity 31 within the clamping mechanism 3, and the clamping cavity 31 includes a first cavity 311 and a second cavity 312 arranged sequentially along a first direction. The first cavity 311 is used to clamp the pipe 100, and the second cavity 312 serves a fine-tuning function. This is achieved by using a correction and limiting component 4... Inserted into the second cavity 312, when the tilt angle of the correction limiting component 41 changes, it will cause a slight change in the tilt angle of the extension direction of the second cavity 312, thereby causing a slight change in the tilt angle of the extension direction of the first cavity 311, and thus changing the tilt angle of the pipe 100; in this way, the tilt angle of the pipe 100 can be corrected, ensuring the levelness of the pipe 100, thereby improving the processing quality of the pipe 100; the size of the second cavity 312 should be adapted to the size of the correction limiting component 41. Since the tilt angle of the pipe 100 is fine-tuned, in order to ensure that the second cavity 312 can swing with the correction limiting component 41, the second cavity 312 should also clamp the correction limiting component 41 in the second direction.

[0039] The pipe necking processing system provided by the present invention can adjust the tilt angle of the pipe 100, ensuring the coaxiality of the pipe 100 and the necking processing cavity 21, thereby improving the processing quality of the pipe 100, increasing the pass rate, and reducing the cost of the pipe necking processing.

[0040] In some embodiments, the correction propulsion mechanism 4 further includes a correction propulsion frame 42, a correction adjustment component 43, and a propulsion power component 44. The correction adjustment component 43 and the correction limiting component 41 are both disposed on the correction propulsion frame 42. The propulsion power component 44 is disposed on the side of the correction propulsion frame 42 away from the reducing machine 2 and is used to drive the correction propulsion frame 42. The correction limiting component 41 includes a correction limiting post 411. The correction adjustment component 43 is used to adjust the tilt angle of the correction limiting post 411 to change the tilt angle of the clamping cavity 31. Specifically, the correction adjustment component 43 cooperates with the second cavity 312. The correction limiting component 41 includes a correction limiting block and a correction limiting post 411. The correction limiting post 411 is installed on the correction limiting block near the reducing machine 2. On one side, the correction limiting post 411 is suspended to facilitate insertion into the second cavity 312; since the adjustment is fine-tuning, during the process of the correction adjustment component 43 undergoing a slight deflection, it will drive the clamping mechanism 3 to undergo a slight deflection, thereby causing the pipe 100 to undergo a slight deflection; the clamping mechanism 3 can be installed on the correction propulsion frame 42, and the clamping mechanism 3 can move synchronously with the correction propulsion frame 42; the propulsion power component 44 can be fixed on the support body 1 to push the entire correction propulsion frame 42 module to move towards the shrinking machine 2; furthermore, the support body 1 is also provided with a track 47, and the correction propulsion frame 42 is slidably set on the track 47; the extension direction of the track 47 is parallel to the first direction to ensure the smooth sliding of the correction propulsion frame 42.

[0041] In some embodiments, a first blocking member 45 is provided on the support body 1, and a second blocking member 46 is provided on the correction and propulsion frame 42. The first blocking member 45 and the second blocking member 46 cooperate to limit the correction and propulsion frame 42 and avoid damage to the shrinking machine 2. The positions of the first blocking member 45 and the second blocking member 46 are adjustable to adapt to different pipe material 100 processing requirements.

[0042] In some embodiments, the correction adjustment component 43 includes an up-and-down adjustment component 431, which includes an up-and-down adjustment support 432 and a first adjustment member 433 and a second adjustment member 434 arranged sequentially along a first direction. The correction limiting component 41 is mounted on the up-and-down adjustment support 432 via the first adjustment member 433 and the second adjustment member 434, and the positions of the first adjustment member 433 and the second adjustment member 434 relative to the up-and-down adjustment support 432 are adjustable to change the up-and-down tilt angle of the correction limiting post 411. This configuration allows the up-and-down tilt angle of the correction limiting component 41 to be adjusted by the up-and-down adjustment component 431, thereby changing the up-and-down tilt angle of the pipe 100; the positional change between the first adjustment member 433 and the second adjustment member 434 and the up-and-down adjustment support 432 changes the tilt angle of the correction limiting component 41 in the front-and-back direction, thereby changing the up-and-down tilt angle of the pipe 100; it is convenient to operate and has high position adjustment accuracy. Furthermore, the number of the first adjusting member 433 and the second adjusting member 434 can be multiple. The first adjusting member 433 and the second adjusting member 434 are provided at both ends of the correction limiting member 41 along the first direction to ensure the stability of the correction limiting member 41. The first adjusting member 433 and the second adjusting member 434 can not only adjust the tilt angle of the correction limiting member 41, but also fasten the correction limiting member 41 to the upper and lower adjusting support 432, so that the correction limiting member 41 can be stably installed on the upper and lower adjusting support 432. The first adjusting member 433 and the second adjusting member 434 can be the same component, such as a stud.

[0043] In some embodiments, the correction adjustment component 43 further includes a left-right adjustment component 435. The left-right adjustment component 435 includes a left-right adjustment support 436 and a third adjustment member 437 and a fourth adjustment member 438 arranged sequentially along the second direction. The left-right adjustment support 436 and the up-down adjustment support 432 are arranged sequentially along the first direction, and the third adjustment member 437 and the fourth adjustment member 438 pass through the left-right adjustment support 436 and are connected to the up-down adjustment support 432. The position between the third adjustment member 437 and the fourth adjustment member 438 and the up-down adjustment support 432 is adjustable to change the left-right tilt angle of the correction limit post 411. The above-described configuration, through the left-right adjustment component 435, enables adjustment of the left-right tilt angle of the correction limiting component 41. Specifically, the left-right adjustment support 436 provides stability, and the third adjustment component 437 and the fourth adjustment component 438 are both mounted on the left-right adjustment support 436. The third adjustment component 437 and the fourth adjustment component 438 change the swing angle of the up-down adjustment support 432, thereby changing the swing angle of the correction limiting component 41 located on the up-down adjustment support 432, and consequently changing the left-right tilt angle of the pipe 100. Through the configuration of the first adjustment component 433, the second adjustment component 434, the third adjustment component 437, and the fourth adjustment component 438, adjustment of the pipe 100 at any tilt angle can be achieved, ensuring that the pipe 100 is coaxial with the necking processing cavity 21, thus improving the processing accuracy of the pipe 100. It should be noted that the left-right direction is parallel to the second direction, and the up-down direction is perpendicular to both the first and second directions.

[0044] In some embodiments, the first adjusting member 433 and the second adjusting member 434 are both studs, and the correction limiting member 41 is provided with a threaded hole. The first adjusting member 433 and the second adjusting member 434 pass through the threaded hole and are threadedly connected to the threaded hole. The first adjusting member 433 and the second adjusting member 434 can be loosened or tightened with a tool. By loosening or tightening the first adjusting member 433 and the second adjusting member 434, the correction limiting member 41 is deflected, which facilitates operation.

[0045] In some embodiments, the third adjusting member 437 and the fourth adjusting member 438 are both studs, and the side wall of the up-down adjusting support 432 is provided with threaded holes. The third adjusting member 437 and the fourth adjusting member 438 are respectively connected to the corresponding threaded holes. The third adjusting member 437 and the fourth adjusting member 438 both extend along the first direction. By tightening or loosening the third adjusting member 437 and the fourth adjusting member 438, the up-down adjusting support 432 can be driven to swing. The left-right adjusting component 435 also includes an elastic component 439 sleeved on the third adjusting member 437 and the fourth adjusting member 438. The two ends of the elastic component 439 abut against the left-right adjusting support 436 and the up-down adjusting support 432 respectively. The elastic component 439 can be a spring, which can drive the up-down adjusting support 432 to reset, so as to facilitate the adjustment of the deflection position of the up-down adjusting support 432.

[0046] In some embodiments, the first cavity 311 is connected to the second cavity 312, and a step is provided between them, with the step facing the second cavity 312; the correction limiting post 411 can be inserted into the second cavity 312 and abut against the step. The correction limiting post 411 drives the clamping mechanism 3 to move by pushing the step. In order to limit the pipe 100, the end of the pipe 100 away from the shrinking machine 2 can abut against the end face of the correction limiting post 411. That is, the pipe 100 is clamped by the clamping mechanism 3 in the first direction, and at the same time, it can also be abutted by the correction limiting post 411 in the first direction, so as to ensure that the pipe 100 is smoothly inserted into the shrinking processing cavity 21.

[0047] In some embodiments, the system also includes an image acquisition component 5, a conveying mechanism 6, and a controller. The image acquisition component 5 is used to acquire the diameter of the pipe 100 and is mounted on the support body 1. The image acquisition component 5 can be a product camera. The conveying mechanism 6 is used to acquire the pipe 100 and control the movement of the pipe 100. The conveying mechanism 6 is mounted on the support body 1. The clamping mechanism 3, the image acquisition component 5, and the correction and propulsion mechanism 4 are all connected to the controller. The controller is used to determine the propulsion distance of the correction and propulsion mechanism 4 according to the pipe diameter and control the operation of the correction and propulsion mechanism 4 according to the propulsion distance. The above setup, using the image acquisition component 5 to photograph the end face of the pipe 100 after each processing, can determine whether the processed pipe 100 is qualified, facilitating subsequent material distribution. Simultaneously, by acquiring the pipe diameter of the processed pipe 100, it can serve as a calibration basis for subsequent processing, improving the accuracy of subsequent pipe 100 processing and preventing batch processing anomalies. The conveying mechanism 6 enables automatic movement of the pipe 100, increasing the degree of automation and reducing the labor intensity of workers. With the help of the controller, automatic adjustment and control can be achieved, improving the accuracy of judging the advance distance.

[0048] In some embodiments, before the necking process, the pipe 100 is first manually loaded into the clamping mechanism 3, and then a first trial processing is performed by the correction and propulsion mechanism 4 to obtain the pipe 100 after the trial processing. The end face shape of the pipe 100 after the first trial processing is acquired by the image acquisition component 5, compared with the end face shape of the standard part, and the comparison result is sent to the controller. The controller determines the positional offset direction of the pipe 100 based on the comparison result between the end face shape of the pipe 100 after the first trial processing and the end face shape of the standard part. For example, if the processing range of the upper part of the end face of the pipe 100 is significantly greater than that of the lower part, it indicates that the pipe 100 has a slight upward warping phenomenon, or the pipe 100... The machining range on the left side of the end face is significantly greater than that on the right side, indicating that the pipe 100 has a slight leftward deviation. Furthermore, it may also include a display. The controller determines the positional offset direction of the pipe 100 based on the comparison results, and then displays the positional offset direction of the pipe 100 on the display, so that the staff can adjust the first adjustment component 433 and the second adjustment component 434, or adjust the third adjustment component 437 and the fourth adjustment component 438 according to the display structure. This setting can reduce errors caused by human judgment, improve the correction accuracy of the correction propulsion mechanism 4, and thus improve the processing quality of the pipe 100. Of course, before processing the same batch, mechanical correction is generally only required once.

[0049] In some embodiments, the system also includes a feeding mechanism 7 and a material cutting mechanism 8. The feeding mechanism 7 is used to carry the pipe 100, and the material cutting mechanism 8 is used to cut the pipe 100. A vibratory feeder can be installed next to the feeding mechanism 7. During the automated production process, the operator puts the products into the vibratory feeder in batches. The vibratory feeder starts working normally and vibrates at a uniform speed to vibrate the products into the feeding mechanism 7 in sequence, which is convenient for feeding. The material cutting mechanism 8 can cut the processed pipe 100. At the same time, according to the detection results of the image acquisition component 5, qualified products and unqualified products are stored separately for easy retrieval later. Furthermore, the conveying mechanism 6 is also used to control the pipe 100 to move from the feeding mechanism 7 to the clamping mechanism 3, or from the clamping mechanism 3 to the material distribution and cutting mechanism 8. The conveying mechanism 6 includes an upper and lower cylinder and a clamping cylinder. The clamping cylinder is located on the upper and lower cylinder. The upper and lower cylinder drives the clamping cylinder to move up and down. The clamping cylinder is used to acquire or release the pipe 100. The feeding mechanism 7 and the material distribution and cutting mechanism 8 are both connected to the controller. The controller is also used to control the actions of the feeding mechanism 7 and the material distribution and cutting mechanism 8 to realize automated operation.

[0050] In some embodiments, the necking machine 2, clamping mechanism 3, and correction and propulsion mechanism 4 are arranged sequentially along a first direction to form a necking processing mechanism; the number of necking processing mechanisms is at least two, and they are arranged sequentially along a second direction; each necking processing mechanism is arranged adjacent to another, and the necking machine 2 in adjacent necking processing mechanisms is located on different sides of the corresponding clamping mechanism 3. That is, the necking machine 2 in two adjacent sets of necking processing mechanisms is located in different positions, and the propulsion direction of the pipe 100 is different, thereby realizing the separate processing of the two ends of the pipe 100; and the feeding mechanism 7 and the material cutting mechanism 8 are respectively located at Each necking processing mechanism is located on different sides of the second direction. Specifically, by setting up multiple sets of necking processing mechanisms, multi-station synchronous operation can be achieved. For example, two sets of necking processing mechanisms can be set up to achieve dual-station operation. At the same time, each set of necking processing mechanisms can share a feeding mechanism 7 and a material distribution and cutting mechanism 8 to improve efficiency. Placing the feeding mechanism 7 and the material distribution and cutting mechanism 8 on different sides of each necking processing mechanism along the second direction allows for better layout and full utilization of the surface space of the supporting body 1. Moreover, the direction of the pipe 100 does not need to be changed, and necking processing can be completed at both ends of the pipe 100. The necking machine 2, clamping mechanism 3, and correction and propulsion mechanism 4 in two adjacent sets of necking processing mechanisms can be arranged in opposite directions, so that the necking machine 2 in different necking processing mechanisms is located in opposite positions, making the layout more reasonable and reducing mutual interference. Furthermore, the image acquisition component 5 may include a first image acquisition component and a second image acquisition component, and the necking machine 2 includes a first necking machine and a second necking machine.

[0051] In addition to the pipe necking processing system described above, the present invention also provides a pipe necking processing method, which can employ the aforementioned pipe necking processing system; the pipe necking processing method includes the following steps.

[0052] Step S1: Determine the initial advance distance L1 of the pipe 100 based on the initial pipe diameter R0, the target pipe diameter r, and the position of the clamping mechanism 3.

[0053] Step S2: Based on the initial advance distance L1, push the pipe 100 into the shrinking machine 2 for shrinking processing, and check the actual pipe diameter R of the processed pipe 100.

[0054] Step S3: Based on the actual pipe diameter R and target pipe diameter r of pipe 100 and the processing angle α of the constriction processing cavity 21, determine the next advance distance L of pipe 100; L=L1+L2, L2=(R / tanα)-(r / tanα); By using the actual processing situation of the previous pipe 100 as the basis for judging the processing of the next pipe 100, timely adjustments can be made to improve the processing accuracy of pipe 100.

[0055] Step S4: Based on the advancing distance L, push the pipe 100 into the shrinking machine 2 for shrinking processing.

[0056] The pipe 100 necking processing method provided by this invention involves the following steps: After the correction and propulsion mechanism 4 completes the product processing, the transport mechanism 6 picks up the product and places it at the position of the image acquisition component 5 for photographic detection. The actual pipe diameter R after processing is detected, and the actual pipe diameter R is compared with the target pipe diameter r of the standard product. By correcting the propulsion distance L1 of the propulsion mechanism 4 during the first pipe 100 necking processing, after completing the processing of the first pipe 100, photographic detection is performed to obtain the actual pipe diameter R of the processed pipe 100. Since the necking angle of the necking machine 2 is α, the next propulsion distance L = L1 + L2 is calculated accordingly. L1 is the template standard value of the correction and propulsion mechanism 4 during the first necking processing, and L2 = (R / tanα) - (r / tanα). L2 serves as the visual compensation value after each photograph and is used as the basis for correcting the propulsion distance of the next pipe 100. The propulsion distance L is adjusted in real time to ensure the processing quality of subsequent pipes 100 and reduce the defect rate. Specifically, when the absolute value of L2 exceeds the alarm threshold, for example, if the absolute value of L2 is greater than 5, it indicates that the processing error of pipe 100 is too large. The equipment will immediately alarm and discard pipe 100. The staff will then reconfirm and correct the parameters of the propulsion mechanism 4 to prevent batch processing abnormalities of pipe 100. For the pipe diameter measurement of pipe 100, it can be either the inner diameter or the outer diameter, but the actual pipe diameter R and the target pipe diameter r should be consistent, i.e., both should be either the outer diameter or both should be the inner diameter.

[0057] Specifically, in one embodiment, the pipe shrinking processing system is a dual-station automatic compensation shrinking mechanism, capable of precise control, automatic feeding, automatic adjustment of the shrinking size and speed of the pipe fittings, and uniform shrinking action; it includes a vibratory feeder, a conveying mechanism 6, a first image acquisition component, a first shrinking machine, a first correction and pushing mechanism, a second image acquisition component, a second shrinking machine, a second correction and pushing mechanism, and a discharge mechanism. After the operator places the product on the vibratory feeder, the vibratory feeder automatically transports the product to the inlet through vibration. Then, the upper and lower cylinders of the conveying mechanism 6 descend to clamp the product. First, the left side of the first image acquisition component takes a picture to detect the shrinking size of the product and determine whether the shrinking size is within the specified range. If not, it is directly transported to the discharge station. If it is within the specified range, the product is placed on the first correction and pushing mechanism. The first correction and pushing mechanism moves the product at a uniform speed according to the pushing distance calculated based on the size captured by the first image acquisition component, pushing the pipe 100 into the first shrinking machine, and then withdrawing it with the pipe 100. At this time, the conveying mechanism 6 picks up the pipe 100. The system automatically moves the product to the second image acquisition unit for a right-side image capture. After the image capture, it checks if the right-side necking is within the specified range. If not, it moves the product directly to the discharge station. If it is, the product is placed on the second correction and propulsion mechanism. The second correction and propulsion mechanism moves the product at a constant speed according to the propulsion distance calculated based on the size captured by the visual image, pushing the product into the second necking machine and then pulling it out. At this point, the transport mechanism 6 picks up the product and places it on the discharge conveyor rail. The side push cylinder pushes the product to the cutting station for cutting and separation, and then pushes it into the receiving box. This system can easily and quickly realize the automatic product feeding and automatic necking process.

[0058] Furthermore, the conveying mechanism 6 moves to the material picking position, and then the upper and lower cylinders descend to perform a clamping action. After clamping the product, it rises to the standby position. The conveying mechanism 6 carries the product to the imaging position of the first image acquisition component for imaging and detection. When creating a new model, a standard size value r is set according to process requirements. In batch automated production, when the deviation between the real-time detected product size R and the standard size r exceeds 5mm, the product is judged to be unqualified and directly ejected, without performing the product necking process, thus improving the precision level and production efficiency of the equipment. After clamping the product, the conveying mechanism 6 moves to the position of the first correction and pushing mechanism. The first clamping mechanism 3 first loosens, and then the conveying mechanism 6 places the product into the clamping mechanism 3. The first clamping mechanism 3 clamps again. At this time, if... Figure 7As shown, the electric cylinder of the first correction and propulsion mechanism moves to the left at a constant speed, sending the product into the first shrinking machine. The first shrinking machine performs the shrinking operation on the product. After the first shrinking machine completes its operation, the electric cylinder of the first correction and propulsion mechanism slowly retracts at a constant speed to the standby position. At this time, the conveying mechanism 6 descends again to remove the processed product. When making new product models, we need to manually place the product into the fixed block of the clamping cylinder first. By adjusting the tilt angle of the clamping cavity 31, we can ensure the processing level of the product and the shrinking processing cavity 21 of the first shrinking machine, ensuring the stability of the product's processing technology. If the product is tilted vertically, we adjust the first adjusting component 433 and the second adjusting component 434. If the product is tilted horizontally, we adjust the third adjusting component 437 and the fourth adjusting component 438. This ensures the fit between the product and the processing hole of the shrinking machine during mass production. When the first blocking component 45 contacts the second blocking component 46, the first correction and propulsion mechanism cannot continue to move, preventing the first correction and propulsion mechanism from colliding with the first shrinking machine and causing damage. The working principle of the second correction and propulsion mechanism, the second clamping mechanism 3, and the second shrinking machine is the same as above, but their movement directions are opposite.

[0059] This pipe shrinking processing system enables cyclic feeding of products and simultaneously completes the shrinking and cutting processes. It can efficiently perform the 100mm pipe shrinking process, ensuring the quality requirements of the pipe products before and after shrinking, improving equipment efficiency, meeting the increasing demands of production capacity, and significantly reducing the space required for mechanical work. This enhances the practicality and timeliness of the equipment, making it suitable for factory use and promotion. It can also reduce the labor intensity of operators, improve work quality, and increase employee job satisfaction.
