Description

Technical Field

[0001] The invention relates to the technical field of metal bellows processing, and in particular to a continuous shape correction method for online detection of metal bellows compensators. Background Art

[0002] There are two main forming methods for metal bellows compensators: mechanical bulging and hydraulic forming. Affected by the elastic properties of the material, after the metal bellows undergo mechanical bulging and hydraulic forming, there is actually a certain difference between the waveform (wave height, wave pitch) of the metal bellows and the designed waveform size. The waveform (wave height, wave pitch) size has an important influence on the stiffness and fatigue life of the metal bellows. Therefore, after the primary forming, secondary forming is often required (i.e., the metal bellows after the primary forming is calibrated) to make the metal bellows waveform (wave height, wave pitch) size meet the requirements, thereby ensuring that the performance indicators of the metal bellows meet the requirements.

[0003] At present, most of the existing metal corrugated compensators are calibrated by a driving mechanism to drive the main shaft to rotate. A supporting wheel is fixed on the main shaft and is coaxial with the main shaft. The supporting wheel has only one supporting tooth. The supporting tooth is used to support a waveform of the metal compensator to be tested, so that the top of the inner side wall of one of the corrugations of the metal compensator just touches the top of the supporting tooth of the supporting wheel and reshapes one of its waveforms. See the attached figure of the specification. Figure 1 As shown. When correcting the waveform of the metal corrugated compensator, if the metal corrugated compensator is long and has many corrugations, there will be many waveforms to be corrected. Once there are multiple waveforms that need to be corrected, each waveform needs to be corrected in turn. After each waveform is corrected, the metal corrugated compensator is manually lifted up and the waveform to be corrected is moved to the corresponding position of the support wheel and then dropped. Then, each waveform to be corrected is corrected in turn. After correction, the waveform after correction is manually measured with a vernier caliper to determine whether it is qualified. If it is unqualified, the waveform of the metal corrugated compensator that has just been corrected is manually placed on the support teeth of the support wheel for re-correction. As a result, a lot of manpower and material resources are wasted, as well as correction time, which reduces the correction efficiency. Summary of the Invention

[0004] (1) Technical issues to be resolved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a continuous shaping method for online detection of metal corrugated compensators, which solves the problem in the prior art that once there are multiple waveforms that need to be shaped, each waveform needs to be shaped in turn. After each waveform is shaped, the metal corrugated compensator is manually lifted up in turn and the waveform to be shaped is moved to the corresponding position of the support wheel and then dropped down. Then, each waveform to be shaped is shaped in turn. After the shaping, the waveform after the shaping is manually measured with a vernier caliper to determine whether it is qualified. If it is unqualified, the waveform of the metal corrugated compensator that has just been shaped is manually placed on the support teeth of the support wheel for re-shaping. As a result, a lot of manpower and material resources are wasted, and the shaping time is wasted, which reduces the efficiency of the shaping.

[0006] (2) Technical solution

[0007] In order to achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] The embodiment of the present invention provides a continuous shape correction method for online detection of metal corrugated compensators.

[0009] The continuous shaping method is based on shaping equipment;

[0010] The shape correction device includes a support frame, a drive assembly, a shape correction assembly, a detection assembly and a controller, wherein the drive assembly and the controller are arranged on the support frame, the shape correction assembly and the detection assembly are movably connected to the support frame, and the drive assembly, the detection assembly and the shape correction assembly are all in communication connection with the controller;

[0011] A support wheel is sleeved and fixed on the driving assembly, and the driving assembly is capable of driving the support wheel to rotate. The outer portion of the support wheel is used to sleeve the metal corrugated compensator, and a plurality of support teeth are arranged on the outer peripheral wall of the support wheel at intervals along the axial direction of the support wheel;

[0012] The shape correction method comprises the following steps:

[0013] S1. Installation of the metal corrugated compensator: installing the metal corrugated compensator on the support wheel, wherein the multiple waveforms of the metal corrugated compensator are respectively engaged with the multiple supporting teeth on the support wheel;

[0014] S2. Initial inspection of the metal corrugated compensator: the controller drives the detection component to start, and after the detection component moves to the detection position, it performs a preliminary inspection on the metal corrugated compensator to obtain an initial inspection signal, and sends the initial inspection signal to the controller;

[0015] S3. Preparation of the shape correction component: The controller receives the initial detection signal in S2 and compares the initial detection signal with the signal of the normal waveform to find out the unqualified waveform on the metal corrugated compensator as the waveform to be corrected. The controller controls the shape correction component to move to the waveform to be corrected, and the shape correction component can press the waveform to be corrected in turn;

[0016] S4. Correction of the metal corrugated compensator: the controller drives the driving assembly to start, thereby driving the support wheel to rotate. Under the pressure of the correction assembly, the waveform to be corrected rotates along a circle tangential to the support wheel to form the corrected waveform;

[0017] S5, detection after correction: the controller drives the detection component to start again, moves the detection component to the detection position again to re-detect the waveform after correction, and sends a secondary detection signal to the controller;

[0018] S6, determination of waveform correction: the controller receives the secondary detection signal in S5, compares it with the signal of the normal waveform and makes a determination;

[0019] If the secondary detection signal is the same as the signal of the normal waveform, the correction is completed;

[0020] If the secondary detection signal is different from the signal of the normal waveform, the above steps S4 to S6 are repeated until the secondary detection signal received by the controller is the same as the signal of the normal waveform.

[0021] Optionally, the following steps are further included before S1:

[0022] S0. Selection of parts: According to the specifications of the metal corrugated compensator to be shaped, select a support wheel that matches the metal corrugated compensator so that the supporting teeth of the support wheel correspond one-to-one with the waveform of the metal corrugated compensator, and select a shaping component that matches the corrugation of the metal corrugated compensator for shaping.

[0023] Optionally, the detection component is a laser detector.

[0024] Optionally, in S2: the detection component can move left and right along the support frame so that there are multiple detection positions, and each detection position can detect multiple waveforms, and the detection signals of the multiple waveforms are respectively transmitted to the controller, and the sum of the waveforms corresponding to the multiple detection positions is equal to the sum of the waveforms of the metal corrugated compensator.

[0025] Optionally, in S2: the detection component is capable of moving up and down relative to the support frame.

[0026] Optionally, S3 includes the following steps:

[0027] S31, the shaping component can be moved left and right along the support frame so that the shaping component moves to the top of the corrugated metal compensator to be shaped;

[0028] S32. The shape correction component slides up and down relative to the support frame to press the metal corrugated compensator on the support wheel onto the drive component.

[0029] Optionally, if S2 detects that multiple waveforms are unqualified, S3 and S4 are repeated for each of the multiple unqualified waveforms in sequence.

[0030] Optionally, the primary detection signal and the secondary detection signal are both wave height and wave distance parameters of the waveform.

[0031] Optionally, after S6, the following steps are further included:

[0032] S7. Disassembly of the metal corrugated compensator: remove the metal corrugated compensator that has passed the S6 shape adjustment to wait for the subsequent shape adjustment of the metal corrugated compensator.

[0033] Optionally, before the detection component detects the metal corrugated compensator in S2, data of a standard waveform of the metal corrugated compensator is recorded as a signal of a normal waveform.

[0034] (3) Beneficial effects

[0035] The beneficial effects of the present invention are as follows: a continuous shaping method for online detection of a metal corrugated compensator of the present invention improves the support wheel structure so that it can fully match the waveform on the metal corrugated compensator. During shaping, the shaping method can fully match the waveform on the metal corrugated compensator with the support teeth on the support wheel. After each waveform on the metal corrugated compensator is detected by the detection component, after an unqualified waveform is detected, the shaping component is controlled by the controller to shape the unqualified waveforms on the metal corrugated compensator in turn. After shaping, the shaping component is again tested to determine whether it is qualified, so as to ensure that the overall waveform after shaping is a qualified waveform. Compared with the existing technology, this method saves manpower and material resources for shaping, while improving shaping efficiency and shaping quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation of is used as a reference. Figure 1 The side where the middle support box seat 21 is located is defined as the "left" side, and the horizontal position of the cross beam 22 at the side plate 23 is defined as the "upper" side.

[0047] See also Figure 2-4 As shown, an embodiment of the present invention proposes a continuous shaping device for online detection of metal corrugated compensators, and the shaping device includes a base 1, a support frame 2, a drive component 3, a shaping component 4, a rotating unit 5, a detection component 6 and a controller 7.

[0048] Support frame 2 is mounted on the top surface of base 1. Drive assembly 3, shape correction assembly 4, detection assembly 6, and controller 7 are all mounted on support frame 2. Shape correction assembly 4 and detection assembly 6 are removably connected to support frame 2. Drive assembly 3, shape correction assembly 4, rotation unit 5, and detection assembly 6 are all communicatively connected to controller 7.

[0049] Furthermore, the support frame 2 includes a support box seat 21, a crossbeam 22 and two side plates 23, and the driving body 31 includes a fixed end and a cantilever connected to each other, and the support wheel 8 is sleeved and fixed on the cantilever.

[0050] The support box seat 21 is arranged at one end of the top of the base 1 , and the fixed end of the driving body 31 is fixedly connected to the top end surface of the support box seat 21 .

[0051] The two side panels 23 are parallel to each other and are vertically disposed on the base 1 .

[0052] The crossbeam 22 is disposed between the two side panels 23 and can connect the two side panels 23 .

[0053] In this embodiment, both side plates 23 are L-shaped when viewed from the side, and the short flat ends of the side plates 23 are mainly used to support the main shaft 312 on the driving body 31. The end of the main shaft 312 away from the driving body 31 serves as a cantilever.

[0054] The two side plates 23 are each provided with a mounting slot 24 for use with the driving body 31 to support the cantilever of the driving body 31 .

[0055] Furthermore, the front end of the mounting groove 24 is provided with an opening, and a positioning pin 25 is provided at the opening. A positioning pin 25 is provided on the side plate 23 on the right side of the cantilever of the main shaft 312 to position the main shaft 312 to cooperate with the rotation function of the rotating unit 5, thereby facilitating the replacement of the support wheel 8.

[0056] The rotating unit 5 includes a rotating motor 51 and a turntable base 52 .

[0057] The rotating motor 51 is disposed in the supporting box seat 21 . The output end of the rotating motor 51 is perpendicular to the output end of the driving motor 311 . The output end of the rotating motor 51 passes through the supporting box seat 21 and is fixedly connected to the turntable base 52 .

[0058] It should be noted that the rotating motor 51 receives the signal sent by the controller 7 and starts and stops after the shape adjustment is completed, which can better realize automation and reduce human resources.

[0059] The turntable base 52 is rotatably connected relative to the supporting box base 21 , and one end of the driving body 31 is fixedly mounted on the turntable base 52 .

[0060] Specifically, when the support wheel 8 needs to be replaced, the drive body 31 stops operating, the rotary motor 51 rotates, driving the turntable base 52, which in turn drives the entire drive assembly 3, causing the drive body 31 to rotate along the vertical center axis of the turntable base 52. This facilitates the installation and removal of the metal corrugated compensator A and the support wheel 8. A round keyway is provided on the main shaft 312, and the support wheel 8 is connected to the main shaft 312 via a round key. The support wheel 3 supports the metal corrugated compensator A during the shaping process.

[0061] The driving assembly 3 includes a driving body 31 , and the exterior of the supporting wheel 8 is used for sleeve-fitting the metal corrugated compensator a.

[0062] Furthermore, the driving body 31 includes a driving motor 311 and a main shaft 312 .

[0063] The drive motor 311 is also electrically connected to the controller 7, and its start and stop are controlled by the controller 7. The drive motor 311 is fixedly mounted on the support box 21 as a fixed end. The output end of the drive motor 311 is arranged parallel to the crossbeam 22. The output end of the drive motor 311 is fixedly mounted to one end of the main shaft 312. The other end of the main shaft 312 passes through the two side plates 23 and is rotatably mounted on the side plate 23 away from the drive motor 311 via a rotating bearing. The support wheel 8 is sleeved and fixed to the main shaft 312. The drive assembly 3 is capable of driving the support wheel 8 to rotate.

[0064] Furthermore, the support wheel 8 includes a wheel body 81 detachably connected to the driving body 31, and support teeth 82 arranged along the circumferential side wall of the wheel body 81, and the support teeth 82 are engaged with the inner side wall of the metal corrugated compensator a. There are multiple support teeth 82, and the multiple support teeth 82 are equally spaced along the axial direction of the wheel body 81.

[0065] The shape correction component 4 can slide along the axial direction of the support wheel 8, and can also move toward or away from the metal corrugated compensator a along the radial direction of the support wheel 8 to press the metal corrugated compensator a on the support wheel 8 onto the driving body 31.

[0066] The driving body 31 can drive the support wheel 8 to rotate, and while driving the support wheel 8 to rotate, it is pressed together with the shape correction component 4 to drive the metal corrugated compensator a to rotate along the tangent circle between it and the support wheel 8.

[0067] It should be noted that the metal corrugated compensator a rotates by the friction between itself and the support wheel 8, and can rotate along the circle tangent to the metal corrugated compensator a and the support wheel 8. At the same time, it moves along the circumference of the support wheel 8, and the tangent point between the metal corrugated compensator a and the support wheel 8 is moving.

[0068] Furthermore, the shape correction component 4 includes a horizontal moving body 41 , a vertical moving body 42 , a shape correction wheel bracket 43 and a shape correction wheel 44 .

[0069] The horizontal moving body 41 is disposed on the crossbeam 22 and can slide left and right along the horizontal direction of the crossbeam 22 .

[0070] The vertical moving body 42 is disposed on the horizontal moving body 41 , and the vertical moving body 42 can slide up and down along the vertical direction of the horizontal moving body 41 .

[0071] The alignment wheel bracket 43 is fixedly connected to the vertical movable body 42 , and the alignment wheel 44 is rotatably installed via a rotating shaft 45 .

[0072] The shaping wheel 44 has shaping grooves corresponding to the corrugated tubes protruding outwards of the metal corrugated compensator a.

[0073] Furthermore, the horizontally movable body 41 includes a first motor 411 fixedly installed at one end of the beam 22, a screw mechanism 412 fixedly connected to the output end of the first motor 411, a first slide groove 413 opened on the beam 22, and the screw mechanism 412 is arranged in the first slide groove 413, and also includes a first slider 414 slidingly connected to the first slide groove 413 and a vertical plate 415 fixedly connected to the first slider 414.

[0074] The vertical plate 415 is slidably connected to the vertical moving body 42 .

[0075] Furthermore, the vertical moving body 42 includes a second motor 421 fixedly mounted on the vertical plate 415, a second slide 422 provided on the vertical plate 415, and a second slider 423 slidingly engaged with the second slide 422. The output end of the second motor 421 is fixedly connected to the second slider 423.

[0076] The second sliding block 423 is fixedly connected to the alignment wheel bracket 43 .

[0077] Specifically, by starting the second motor 421, the shaping wheel 44 on the shaping wheel bracket 43 can be moved in the vertical (perpendicular) direction. The shaping wheel 44 and the support wheel 8 can be replaced according to the specifications of the workpiece to be shaped, and are universal. Furthermore, when the metal corrugated compensator a is shaped, the shaping wheel 44 first drives the first slider 414 through the first motor 411, and then drives the vertical moving body 42 on the vertical plate 415 to slide in the left and right directions as a whole. When it slides to the top of the metal corrugated compensator a and the initial bellows, the second motor 421 is started again. The second motor 421 drives the second slider 423 to drive the shaping wheel bracket 43 to move down and engage with the support wheel 8. Then, by starting the main shaft 32 component of the driving component 3, the metal corrugated compensator a is driven to rotate, thereby realizing the shaping of the waveform of the metal corrugated compensator a. This device can realize the continuous shaping of the corrugation of the metal corrugated compensator a by loading and unloading the metal bellows in one go.

[0078] Further, see Figure 7 As shown, the detection assembly 6 includes a transverse movement assembly 61, a longitudinal movement assembly 62, and a laser detector body 63. The transverse movement assembly 61 is capable of moving left and right along the crossbeam 22. The longitudinal movement assembly 62 is fixedly connected to the transverse movement assembly 61 and is capable of moving up and down relative to the crossbeam 22. The laser detector body 63 is fixedly mounted on the longitudinal movement assembly 62.

[0079] Specifically, the lateral moving component 61 includes a third slider 611, and the third slider 611 is connected to the screw mechanism 412 driven by the first motor 411 of the horizontal moving body 42, and the third slider 611 performs left and right linear reciprocating motion along the first slide groove 413 under the drive of the screw mechanism 412.

[0080] The longitudinal movement assembly 62 includes a third motor 621, a longitudinal slide rail 622, and a fourth slider 623. The third motor 621 is fixedly mounted on the third slider 611 and can drive the fourth slider 623 to move up and down along the longitudinal slide rail 622, thereby driving the laser detector body 63 to move up and down.

[0081] It should be noted that the detection component 6 uses a line laser detector. The detection range of the line laser detector is in the shape of an isosceles trapezoid (see Figure 8As shown), that is, it is affected by the line width of the line laser detector. Once the waveform is not within the range of the online laser detector, the waveform cannot be effectively detected, resulting in low detection efficiency and poor detection effect. Moreover, even if the waveform is within the detection range of the online laser detector, the closer the probe of the offline laser detector is, the higher the detection accuracy, that is, the range of optimal detection accuracy can be formed. Once the metal corrugated compensator a is longer, the waveforms will also be more. If the laser detector cannot move left and right, the waveforms farther away from the laser detector cannot be detected. If the laser detector cannot move up and down, it cannot ensure that the waveform of the metal corrugated compensator a is within the optimal detection range, resulting in poor detection effect and poor detection accuracy of the line laser detector.

[0082] In other words, the lateral movement assembly 61 can be moved left and right to establish multiple different testing positions in the horizontal direction, accommodating the testing of metal corrugated compensator A waveforms of varying lengths, thereby ensuring that even longer waveforms can be fully inspected. Furthermore, when the online laser detector is not in use, the lateral movement assembly 61 avoids the need for the shape correction assembly 4, ensuring its proper function and thus not affecting the overall inspection of the metal corrugated compensator A. Furthermore, the straight edge sections at both ends of the metal corrugated compensator A can be inspected, providing more comprehensive inspection data for easier reference.

[0083] In this embodiment, the purpose of the laser detector body 63 being able to move up and down is to ensure that the waveform of the metal corrugated compensator a is within the detection range of the best detection accuracy, thereby improving the detection accuracy and detection effect.

[0084] It should be noted that in addition to the detection method of the laser detector body 63, other devices with detection functions, such as point laser detectors, ultrasonic ranging sensors, image measurement sensors, and contact sensors, are also within the scope of protection of this application.

[0085] In this embodiment, the detection component 6 only shows the detection function of the U-shaped waveform. Of course, it can also play a separate detection role for the Ω-shaped waveform and non-metallic corrugated compensator, thereby achieving better detection results.

[0086] It should be noted that the alignment assembly 4 achieves left-right movement on the crossbeam 22 via a horizontally movable body 41 and vertically moves up and down via a vertically movable body 42. Other mechanisms for achieving movement and adjustment, such as dovetail grooves, ball screws, and guide rails, are also protected. The same applies to the selection of the lateral and longitudinal movable assemblies 61 and 62 of the detection assembly 6.

[0087] The present invention provides a continuous shaping device for a metal corrugated compensator, wherein a support frame 2 is provided on a base 1, a drive assembly 3 is provided on the support frame 2, and a metal corrugated compensator a is sleeved on the drive assembly 3, with both ends of the drive assembly 3 being supported by the support frame 2. Moreover, the drive assembly 3 cooperates with the shaping assembly 4 to drive the metal corrugated compensator a to rotate while shaping its waveform. In addition, the shaping assembly 4 slides in the axial and radial directions relative to the metal corrugated compensator a to cooperate with the continuous shaping of multiple corrugated segments of the metal corrugated compensator a, thereby improving the shaping efficiency. In the prior art, when shaping metal bellows, it is impossible to shape any waveform individually, and for shaping of longer and thinner-walled bellows, the end farther from the clamping end is very likely to tilt downward, resulting in a technical problem of poor shaping effect.

[0088] The invention discloses a continuous shape correction method for online detection of a metal corrugated compensator. The continuous shape correction method is based on a shape correction device.

[0089] It should be noted that the following steps are also included before S1:

[0090] S0. Component Selection: Based on the specifications of the metal corrugated compensator A to be calibrated, select a support wheel 8 that matches the metal corrugated compensator A, ensuring that its supporting teeth 82 correspond one-to-one with the corrugated shape of the metal corrugated compensator A. Select the calibrating wheel 44 of the calibrating assembly 4 that matches the corrugation of the metal corrugated compensator A for calibration, and connect it to the calibrating wheel seat 43 via a connecting shaft. The first and third sliders 414 and 611 are positioned within the first slot 413 of the crossbeam 22.

[0091] S1. Installation of metal corrugated compensator: First install the metal corrugated compensator a, start the control program of the rotating motor 51, and rotate the turntable base 52, so that the main shaft 32 on the driving body 31 rotates horizontally outward (perpendicular to the paper surface) with the turntable base 52 as the central rotation axis. When it rotates to a suitable angle, pause (such as Figure 5 ). According to the specifications of the metal corrugated compensator a to be calibrated, install (replace) the round head flat key and the support wheel 8 on the main shaft 312. After the metal corrugated compensator a is installed, the control program of the rotating motor 51 is adjusted on the control panel of the controller 7 to rotate the turntable base 52 back to the positioning groove 24, insert the positioning pin 25, and complete the installation of the metal corrugated compensator a (such as Figure 6 The metal corrugated compensator a is mounted on the supporting wheel 8 , and the multiple waveforms of the metal corrugated compensator a are respectively engaged with the multiple supporting teeth 82 on the supporting wheel 8 .

[0092] Furthermore, before the detection component 6 detects the metal corrugated compensator in S2, the laser detector body 63 scans the qualified waveform and converts it into an electronic signal and stores it in the controller 7. Specifically, the data of the standard waveform of the metal corrugated compensator is recorded, and the standard waveform is referenced to the normal tolerance range to obtain an electronic signal of the normal waveform for comparison with the initial detection signal collected in S2 or the secondary detection signal in S5.

[0093] S2. Initial Inspection of the Metal Corrugated Compensator: Controller 7 activates detection assembly 6. After detection assembly 6 moves to the inspection position, controller 7 controls detection assembly 6's longitudinal movement assembly 62 to move laser detector body 63 to a suitable vertical position and stop. Then, transverse movement assembly 61 moves laser detector body 63 horizontally to the inspection position. Laser detector body 63 performs a preliminary inspection of the waveform on metal corrugated compensator a at the inspection position, generates a preliminary inspection signal, and transmits the preliminary inspection signal to controller 7.

[0094] Furthermore, in S2: the detection component 6 can move left and right along the first slide groove 413 on the beam 22 of the support frame 2 through the fourth slider 611 of the transverse moving component 61, so that there are multiple detection positions, and each detection position can detect multiple waveforms, and transmit the detection signals of the multiple waveforms to the controller 7 respectively, and the sum of the waveforms corresponding to the multiple detection positions is equal to the sum of the waveforms of the metal corrugated compensator.

[0095] Specifically, if the axial length of metal corrugated compensator a is 2m and its outer circumferential sidewall is uniformly spaced with 50 corrugated teeth, the inspection positions are divided into five points from left to right: the first inspection position, the second inspection position, the third inspection position, the fourth inspection position, and the fifth inspection position. Furthermore, when the laser detector body 63 is in the first inspection position, it can inspect all 10 corrugated teeth. Similarly, all 50 corrugated teeth can accurately inspect the conformity of the waveform.

[0096] It should be noted that if S2 detects that multiple waveforms are unqualified, S3 and S4 are repeated for each of the multiple unqualified waveforms in sequence.

[0097] Furthermore, in S2: the detection assembly 6 can be moved up and down relative to the support frame 2 via the longitudinal movement assembly 62, in order to adjust the working range of the laser detector body 63 in the transverse direction.

[0098] Furthermore, in this embodiment, the initial inspection of the metal corrugated compensator a not only checks for acceptable waveforms but also measures the width and other dimensions between adjacent waveforms, ensuring that the calibrating wheels 44 of the calibrating assembly 4 accurately move directly above the waveform to be inspected when moving laterally along the crossbeam 22. If subsequent inspections of processed waveforms are required, the distance between adjacent waveforms can also be measured, allowing the calibrating assembly 4 to be moved to a more precise position.

[0099] S3. Preparation of the shaping component 4: The controller 7 receives the initial detection signal in S2, and compares the initial detection signal with the signal of the normal waveform, finds the unqualified waveform on the metal corrugated compensator a as the waveform to be shaped, and the controller 7 controls the shaping component 4 to move above the waveform to be shaped, and the shaping component 4 can press the waveform to be shaped in turn.

[0100] Furthermore, S3 includes the following steps:

[0101] S31. The shaping component 4 can move left and right along the supporting frame 2 so that the shaping component 4 moves to the top of the waveform of the metal corrugated compensator to be shaped.

[0102] S32 , the shape correction component 4 slides up and down relative to the support frame 2 , pressing the metal corrugated compensator on the support wheel 8 onto the drive component 3 .

[0103] S4. Shape adjustment of the metal corrugated compensator: the controller 7 drives the driving component 3 to start, so as to drive the support wheel 8 to rotate. Under the pressure of the shape adjustment component 4, the waveform to be shaped rotates along the tangent circle between it and the support wheel 8 to form the shaped waveform.

[0104] Specifically, after the horizontal moving body 41 cooperates to move to the appropriate position directly above the waveform of the metal corrugated compensator a to be shaped, the vertical moving body 42 makes the shaping wheel 44 contact with the rotating metal corrugated compensator a and press it on the support wheel 8, and the driving motor 311 makes the main shaft 312 drive the support wheel 8 and the metal corrugated compensator a to rotate to perform the first corrugation to be shaped. After the first corrugation to be shaped is completed, the horizontal moving body 41 and the vertical moving body 42 cooperate to continue working, driving the shaping wheel seat 43 and the shaping wheel 44 to move upward and leave the metal corrugated compensator a, and move to above the next designated shaping position of the metal corrugated compensator a to be shaped. The horizontal moving body 41 stops working, and the vertical moving body 42 continues to work to make the shaping wheel contact with the rotating metal bellows to perform the shaping process of the second corrugation to be shaped, and repeats in sequence until the last corrugation to be shaped is completed.

[0105] S5. Detection after correction: The controller 7 drives the lateral moving component 61 and the longitudinal moving component 62 of the detection component 6 to the appropriate detection positions again to start detection in sequence, moves the detection component 6 to the detection position again to re-detect the waveform after correction, and sends the secondary detection signal of the re-detection to the controller 7.

[0106] Furthermore, the primary detection signal and the secondary detection signal are both wave height and wave distance parameters of the waveform. Moreover, the primary detection signal can also be used to perform auxiliary detection of parameters such as the number of waves and the total length.

[0107] S6. Determination of waveform correction: The controller 7 receives the secondary detection signal in S5, compares it with the signal of normal waveform and makes a judgment.

[0108] If the secondary detection signal is the same as the normal waveform signal, the correction is completed.

[0109] If the secondary detection signal is different from the signal of the normal waveform, the above steps S4 to S6 are repeated until the secondary detection signal received by the controller 7 is the same as the signal of the normal waveform.

[0110] Furthermore, after S6, the following steps are also included:

[0111] S7. Disassembly of metal corrugated compensator: Remove the metal corrugated compensator that has passed the S6 calibration and wait for the subsequent calibration of the metal corrugated compensator.

[0112] After the metal bellows has been calibrated and qualified, remove the positioning pin 25 and activate the control program for the rotary motor 51 on the control panel of the controller 7 to rotate the turntable base 52, thereby causing the spindle 312 to rotate horizontally outward with the turntable base 52 as the center. When the rotation reaches the appropriate angle, remove the metal bellows compensator a. Once again activate the control program for the rotary motor 51 on the control panel of the controller 7 to return the spindle 312 to its original position, insert the positioning pin 52, and complete the workpiece removal.

[0113] The present invention provides a continuous shaping method for online inspection of metal corrugated compensators. By improving the support wheel structure so that it can fully match the waveform on the metal corrugated compensator a, the shaping method can fully match the waveform on the metal corrugated compensator a with the support teeth 82 on the support wheel 8 during shaping. Each waveform on the metal corrugated compensator a is inspected by the inspection component 6. After detecting an unqualified waveform, the controller 7 controls the shaping component 4 to sequentially shape the unqualified waveforms on the metal corrugated compensator a. After shaping, the unqualified waveforms are again inspected by the inspection component 6 to determine whether they are qualified, ensuring that the overall waveform after shaping is qualified. Compared with existing technologies, this method saves manpower and material resources for shaping, while improving shaping efficiency and quality. The invention solves the problem in the prior art that once there are multiple waveforms that need to be calibrated, each waveform needs to be calibrated in turn. After each waveform is shaped, the metal corrugated compensator is manually lifted up in turn and the waveform to be calibrated is moved to the corresponding position of the supporting wheel and then dropped. Then, each waveform to be calibrated is calibrated in turn. After the calibration, a vernier caliper is manually used to measure whether the calibrated waveform is qualified. If it is unqualified, the waveform that has just been calibrated by the metal corrugated compensator is manually placed on the supporting teeth of the supporting wheel for re-calibration. As a result, a lot of manpower and material resources are wasted, and the calibration time is wasted, which reduces the efficiency of the calibration.
