Description

Technical Field

[0001] This invention relates to the field of automated cutting equipment, and in particular to an automated feeding and cutting equipment for quenched tubes. Background Technology

[0002] In the automated fixed-length cutting process of long strip workpieces such as steel bars and pipes, a detection mechanism is needed to detect whether the workpiece has been completely cut. Based on the detection result, it is determined whether the next feeding can proceed. In the existing technology, through-beam photoelectric sensors are often used to sense whether the workpiece has been cut. For example, Chinese utility model patent CN219634495U discloses a large-diameter pipe uncut detection device based on a pressure feeding mechanism. Through the set pipe traction mechanism, cutting detection mechanism and pressure feeding mechanism, the device can realize the traction, cutting and pressure feeding of the pipe after cutting. The cutting detection mechanism includes a through-beam grating that can detect whether the pipe cutting is complete, avoiding damage to the pipe surface and the downstream automated detection and packaging device caused by the pipe not being cut during the extrusion production process.

[0003] Because quenched tubes have high hardness, water or other coolants are needed to cool them down during the cutting process. During the cutting process, dust, water or other coolants, sand and other substances are generated, resulting in a harsh environment in the entire cutting cavity. Therefore, it is difficult to detect whether the quenched tube has been cut using existing through-beam photoelectric sensors, which can easily lead to misjudgments, thus affecting the automated feeding and cutting of quenched tubes.

[0004] Therefore, it is necessary to provide a technical solution to address the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automated quenching tube cutting device and an automated feeding and cutting method, which can solve the technical problem that the existing through-beam photoelectric sensor cannot accurately determine whether the quenching tube has been cut, thus affecting the automated feeding and cutting of the quenching tube.

[0006] To solve the above-mentioned technical problems, the present invention provides an automated feeding and cutting equipment for quenched tubes, including a control system, a feeding device, a cutting device, and a cutting detection mechanism, wherein the feeding device, the cutting device, and the cutting detection mechanism are all connected to the control system.

[0007] The feeding device includes a first frame, on which a feeding mechanism and a first driving component are provided. The first driving component is used to drive the feeding mechanism to move back and forth along the first frame. The feeding mechanism includes a fixing component for fixing the quenching tube and a second driving component for driving the fixing component to rotate.

[0008] The cutting device is located at the discharge end of the feeding device. The cutting device includes a second frame, on which a cutting mechanism for cutting the quenched tube is provided. The cutting mechanism includes a grinding wheel.

[0009] The cutting detection mechanism includes a driven detection roller, a detection block, and a proximity switch. The driven detection roller is rotatably disposed on the side of the grinding wheel away from the feeding device. The detection block is fixedly connected to one end of the driven detection roller. The proximity switch is disposed opposite to the outer peripheral side of the detection block. The driven detection roller can contact the surface of the quenching tube, and the quenching tube can drive the driven detection roller and the detection block to rotate. The minimum distance between each position on the outer peripheral side of the detection block and the proximity switch is at least partially different.

[0010] Furthermore, the cutting detection mechanism includes a bracket, and the two ends of the driven detection pressure roller are rotatably connected to the bracket via a rotating shaft, one of the rotating shafts extending to the outside of the bracket and fixedly connected to the detection block, and the proximity switch is fixed on the bracket.

[0011] Furthermore, the detection block includes an annular portion, on which a plurality of protrusions are evenly arranged on the circumferential side surface, and the annular portion is sleeved on the rotating shaft.

[0012] Furthermore, a protective cover is provided on the side of the bracket near the detection block, and both the detection block and the proximity switch are disposed inside the protective cover.

[0013] Furthermore, the cutting detection mechanism also includes a third driving component, which is connected to the bracket and is used to drive the bracket away from or closer to the quenching tube.

[0014] Furthermore, the cutting device also includes a support mechanism mounted on the second frame for supporting the quenched tube. There are two support mechanisms, which are located on both sides of the grinding wheel. The support mechanism includes a support base and two support rollers rotatably mounted on the support base.

[0015] Furthermore, the cutting device also includes a support plate for placing the quenching tube, with both ends of the support plate respectively disposed on the two support mechanisms, and two support rollers in the support mechanisms passing through the support plate and contacting the quenching tube.

[0016] Furthermore, the feeding mechanism also includes a support base, in which a slider is slidably disposed. The fixing component and the second driving component are both disposed on the slider, and a fourth driving component is disposed on the support base to drive the slider to move up and down.

[0017] Furthermore, the cutting mechanism also includes a fifth drive assembly for driving the grinding wheel to rotate and a sixth drive assembly for driving the grinding wheel to move up and down.

[0018] On the other hand, the present invention also provides an automatic feeding and cutting method for quenched tubes, which is performed using the automatic feeding and cutting equipment for quenched tubes described in any of the above embodiments; the automatic feeding and cutting method includes the following steps:

[0019] S1: The quenched tube to be cut is fixedly installed on the fixed component of the feeding mechanism. After installation, the control system controls the first drive component to move, and the first drive component drives the feeding mechanism to move a certain distance in the direction of the cutting device.

[0020] S2: After the feeding mechanism is in place, the control system controls the second drive component to move. The second drive component drives the fixed component to rotate. The quenching tube rotates synchronously with the fixed component. At the same time, the control system controls the driven detection roller in the cutting detection mechanism to move downward until it contacts the outer surface of the quenching tube. The driven detection roller rotates synchronously with the quenching tube.

[0021] S3: Next, the control system controls the grinding wheel in the cutting mechanism to cut the quenched tube. When the quenched tube is not cut, the quenched tube located on the side of the grinding wheel away from the feeding device still rotates with the fixed component. The driven detection pressure wheel rotates synchronously, and the detection block also rotates synchronously with the driven detection pressure wheel. Since the minimum distance between each position on the outer periphery of the detection block and the proximity switch is at least partially different, the proximity switch can continuously detect the signal of distance change. The proximity switch does not send a "cut-off" signal to the control system.

[0022] S4: When the quenching tube is cut off, the quenching tube located on the side of the grinding wheel away from the feeding device cannot rotate with the fixed component. The driven detection pressure roller stops rotating synchronously, and the detection block also stops rotating synchronously. At this time, the proximity switch cannot detect the signal of distance change, and the proximity switch sends a "cut-off" signal to the control system.

[0023] S5: When the control system receives the "cut-off" signal, the control system controls the first drive component to move again. The first drive component drives the feeding mechanism to move a certain distance in the direction of the cutting device. Steps S2-S5 are repeated in sequence until all the quenched tubes to be cut on the fixed component are cut, so as to realize the automated feeding and cutting of the quenched tubes.

[0024] The beneficial effects of the present invention are as follows:

[0025] By incorporating a driven detection roller capable of contacting the surface of the quenched tube within the cutting detection mechanism, and with one end of the driven detection roller fixedly connected to a detection block, the driven detection roller is positioned on the side of the grinding wheel furthest from the feeding device. When the grinding wheel does not completely cut the quenched tube, the quenched tube on the side furthest from the feeding device continues to rotate along with the fixed assembly, simultaneously driving the driven detection roller and the detection block to rotate synchronously. Since the minimum distance between various positions on the outer periphery of the detection block and the proximity switch is at least partially different, the proximity switch can continuously detect distances. When the distance changes, the proximity switch does not send a "cut-off" signal to the control system. When the quenching tube is completely cut off, the quenching tube located on the side of the grinding wheel away from the feeding device cannot rotate with the fixed component. The driven detection roller and the detection block stop rotating synchronously. At this time, the proximity switch cannot detect the distance change signal, and it is determined that the cut product has been completely cut off. The proximity switch then sends a "cut-off" signal to the control system. When the control system receives the "cut-off" signal, it controls the feeding device to feed for the next cut, thereby realizing automated feeding and cutting of the quenching tube. By setting a cutting detection mechanism instead of the through-beam photoelectric sensor in the existing technology, the detection block and proximity switch in the cutting detection mechanism can be set away from the cutting cavity or isolated from the cutting cavity. This ensures that dust, water, or other impurities such as coolant and sand generated during the cutting of the quenching tube will not affect the detection of the proximity switch, guaranteeing the accuracy of the quenching tube cutting detection, realizing automated feeding and cutting of the quenching tube, improving production efficiency, and saving labor costs.

Detailed Implementation

[0035] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0036] Example 1

[0037] like Figures 1 to 7 As shown in the figure, this embodiment provides an automated feeding and cutting equipment for quenched tubes, including a control system (not shown in the figure), a feeding device 1, a cutting device 2, and a cutting detection mechanism 3. The feeding device 1, the cutting device 2, and the cutting detection mechanism 3 are all connected to the control system.

[0038] The feeding device 1 includes a first frame 11, on which a feeding mechanism 12 and a first drive assembly 13 are provided. The first drive assembly 13 is used to drive the feeding mechanism 12 to move back and forth along the first frame 11. The feeding mechanism 12 includes a fixing assembly 121 for fixing the quenching tube 10 and a second drive assembly 122 for driving the fixing assembly 121 to rotate.

[0039] The cutting device 2 is disposed at the discharge end of the feeding device 1. The cutting device includes a second frame 21, and a cutting mechanism 23 for cutting the quenched tube 10 is disposed on the second frame 21. The cutting mechanism 23 includes a grinding wheel 231.

[0040] The cutting detection mechanism 3 includes a driven detection pressure roller 32, a detection block 33, and a proximity switch 34. The driven detection pressure roller 32 is rotatably disposed on the side of the grinding wheel 231 away from the feeding device 1. The detection block 33 is fixedly connected to one end of the driven detection pressure roller 32. The proximity switch 34 is disposed opposite to the outer peripheral side of the detection block 33. The driven detection pressure roller 32 can contact the surface of the quenching tube 10, and the quenching tube 10 can drive the driven detection pressure roller 32 and the detection block 33 to rotate. The minimum distance between each position of the outer peripheral side of the detection block 33 and the proximity switch 34 is at least partially different.

[0041] Specifically, the first drive assembly 13 may include a servo motor and a transmission gear mounted on the feeding mechanism 12. The output end of the servo motor is connected to the transmission gear. A rack that meshes with the transmission gear is provided on one side of the first frame 11 along the conveying direction of the quenching tube 10. When the servo motor rotates, it drives the transmission gear to rotate, and the transmission gear meshes with the rack, thereby driving the feeding mechanism 12 to move back and forth on the first frame 11. Of course, in other embodiments, the first drive assembly 13 may also adopt a telescopic cylinder, a motor screw nut, or other drive mechanism. The second driving component 122 can be a driving motor, which is connected to the fixed component. The driving motor drives the fixed component 121 to rotate, thereby driving the quenching tube 10 to rotate. The fixed component 121 can be a wedge-type inner support clamping mechanism. The wedge-type inner support clamping mechanism is inserted into the interior of one end of the quenching tube 10. The driving component in the wedge-type inner support clamping mechanism drives the wedge to expand outward, thereby pressing against the inner wall of the quenching tube 10 to achieve clamping and positioning of the quenching tube 10. Of course, in some other embodiments, the fixed component 121 can also be a positioning claw.

[0042] In this embodiment, since the quenching tube 10 rotates during the cutting process, a driven detection roller 32 is provided in the cutting detection mechanism 3 to contact the surface of the quenching tube 10. One end of the driven detection roller 32 is fixedly connected to a detection block 33. The driven detection roller 32 is located on the side of the grinding wheel 231 away from the feeding device 1, and the grinding wheel 231 divides the quenching tube 10 into two parts: the part away from the feeding device 1 is the finished product part, and the part close to the feeding device 1 is the main body part. That is, the driven detection roller 32 contacts the surface of the finished product part. When the grinding wheel 231 does not completely cut the finished product part from the main body part, the finished product part will rotate along with the main body part under the drive of the fixing component 121. The rotation of the finished product part drives the driven detection roller 32 to rotate, and the detection block 33 also follows the driven detection roller 32. The rotational motion is synchronized. Since the minimum distance between the various positions on the outer periphery of the detection block 33 and the proximity switch 34 is at least partially different, the proximity switch 34 can continuously detect the signal of distance change. The proximity switch 34 does not send a "cut-off" signal to the control system. When the cut-off part is completely cut off, that is, the cut-off part is separated from the main body, the cut-off part cannot rotate with the main body. The driven detection pressure roller 32 stops rotating synchronously, and the detection block 33 also stops rotating synchronously. At this time, the proximity switch 34 cannot detect the signal of distance change, so it is determined that the cut-off part has been completely cut off, and the proximity switch 34 sends a "cut-off" signal to the control system. When the control system receives the "cut-off" signal, the control system controls the feeding device 1 to feed the material for the next cut, thereby realizing the automated feeding and cutting of the quenching tube 10. By setting a cutting detection mechanism 3 instead of the through-beam photoelectric sensor in the prior art, the detection block 33 and proximity switch 34 in the cutting detection mechanism 3 can be set away from the cutting cavity or isolated from the cutting cavity. This ensures that dust, water, or other impurities such as coolant and sand generated during the cutting of the quenched tube will not affect the detection of the proximity switch 34, thus ensuring the accuracy of the cutting detection of the quenched tube, realizing the automated feeding and cutting of the quenched tube, improving production efficiency, and saving labor costs.

[0043] Further, the cutting detection mechanism 3 includes a bracket 31, and the two ends of the driven detection pressure roller 32 are rotatably connected to the bracket 31 via rotating shafts 35. One of the rotating shafts 35 extends to the outside of the bracket 31 and is fixedly connected to the detection block 33. The proximity switch 34 is fixed to the bracket 31. Specifically, as shown... Figure 6-7As shown, a mounting groove is provided through one end of the bracket 31 near the quenching tube 10. Both ends of the driven detection pressure roller 32 are connected to a rotating shaft 35. The rotating shaft 35 is rotatably mounted in the two side walls of the mounting groove through bearings. The rotating shaft 35 on the side away from the grinding wheel 231 passes through the side wall of the mounting groove and extends to the outside of the bracket 31. The detection block 33 is installed at the end of the rotating shaft 35 away from the bracket 31. This arrangement facilitates the driven detection pressure roller 32 to drive the detection block 33 to rotate. On the other hand, it allows the detection block 33 and the proximity switch 34 to be positioned away from the grinding wheel 231, reducing the impact of impurities generated during the cutting process on the detection block 33 and the proximity switch 34.

[0044] Furthermore, such as Figure 7 As shown, the detection block 33 includes an annular portion 332, and a plurality of protrusions 333 are evenly arranged on the circumferential side surface of the annular portion 332. The annular portion 332 is sleeved on the rotating shaft 35. In this embodiment, by evenly arranging a plurality of protrusions 333 on the circumferential side surface of the annular portion 332, the minimum distance between each position of the outer circumferential side surface of the detection block 33 and the proximity switch 34 is at least partially different, so that the proximity switch 34 can sensitively detect whether the detection block 33 is rotating, thereby accurately and quickly determining whether the quenching tube 10 has been cut off. Of course, in other embodiments, the detection block 33 can also adopt other shapes, such as gear-shaped, elliptical, etc.

[0045] Furthermore, such as Figure 4 As shown, a protective cover 36 is provided on the side of the bracket 31 near the detection block 33, and both the detection block 33 and the proximity switch 34 are disposed within the protective cover 36. In this embodiment, by providing the protective cover 36, both the detection block 33 and the proximity switch 34 are disposed within the protective cover, which can effectively isolate the detection block 33 and the proximity switch 34 from the cutting cavity. On the one hand, this can protect the proximity switch 34 and extend its service life; on the other hand, it can isolate the influence of impurities generated during the cutting process on the detection of the detection block 33 and the proximity switch 34, ensuring the accuracy of the detection.

[0046] Furthermore, such as Figure 4 and 6As shown, the cutting detection mechanism 3 further includes a third driving component 37, which is connected to the bracket 31. The third driving component 37 is used to drive the bracket 31 away from or towards the quenching tube 10. Specifically, the cutting detection mechanism 3 also includes a mounting base 38, which is fixedly connected to one side of the bearing mechanism 22. The third driving component 37 can be a driving cylinder. The output end of the driving cylinder is rotatably connected to a driving connecting block 30. The end of the driving connecting block 30 away from the driving cylinder is fixedly connected to a transmission shaft 39. The transmission shaft 39 is parallel to the central axis of the driven detection pressure roller 32, and the transmission shaft 39 is rotatably connected to the mounting base 38. The end of the bracket 31 away from the mounting groove is mounted on the transmission shaft 39. When the output end of the driving cylinder performs a telescopic movement, it will drive the driving connecting block 30 to rotate, thereby driving the transmission shaft 39 to rotate, and finally driving the bracket 31 to rotate, so that the driven detection pressure roller 32 approaches or moves away from the surface of the quenching tube 10, so that the driven detection pressure roller 32 can contact the surface of the quenching tube 10.

[0047] Furthermore, such as Figure 4-5 As shown, the cutting device 2 further includes a support mechanism 22 mounted on the second frame 21 for supporting the quenched tube 10. There are two support mechanisms 22, each located on one side of the grinding wheel 231. Each support mechanism 22 includes a support base 221 and two support rollers 222 rotatably mounted on the support base 221. In this embodiment, by providing support mechanisms on both sides of the grinding wheel 231, the quenched tube 10 located on both sides of the grinding wheel 231 can be supported during the cutting process, preventing the quenched tube 10 from bending and deforming under stress. Furthermore, the support rollers 222 in the support mechanism 22 rotate along with the quenched tube 10 during rotation, reducing the frictional resistance between the quenched tube 10 and the support mechanism 22, ensuring normal rotation of the quenched tube 10.

[0048] Furthermore, such as Figure 4-5As shown, the cutting device 2 also includes a support plate 24 for placing the quenching tube 10. The two ends of the support plate 24 are respectively mounted on the two support mechanisms 22, and the two support rollers 222 in the support mechanisms 22 pass through the support plate 24 and contact the quenching tube 10. In this embodiment, by further providing a support plate 24 above the two support mechanisms 22, the support for the quenching tube 10 is further increased. When the length of the cut finished section of the quenching tube 10 is less than the distance between the two support mechanisms 22, and the end of the cut finished section away from the grinding wheel 231 cannot be supported on the support mechanism 22, the support plate 24 can support the cut finished section, thereby increasing the application range of the automated feeding and cutting equipment for quenching tubes in this embodiment. Furthermore, to ensure the function of the support rollers 222, the support plate 24 has an opening at the position corresponding to the support rollers 222, allowing the support rollers 222 to pass through the opening and contact the quenching tube 10.

[0049] Furthermore, such as Figure 3 As shown, the feeding mechanism 12 also includes a support base 123, in which a slider 124 is slidably disposed. The fixing component 121 and the second driving component 122 are both disposed on the slider 124. A fourth driving component 125 is disposed on the support base 123 to drive the slider 124 to move up and down. In this embodiment, by setting the slider 124 and the fourth driving component 125, the height of the fixing component 121 can be adjusted according to the diameter of the quenched tube 10 in actual production, thereby adapting to the processing of quenched tubes 10 of different diameters and improving applicability. Specifically, the support base 123 includes a gantry frame, and the slider 124 is slidably disposed in the gantry frame. The fourth drive assembly 125 can be a drive mechanism such as a drive cylinder, a motor screw nut, etc. The fourth drive assembly 125 is installed on the top of the support base 123, and its working end extends downward through the top of the support base 123 and connects to the top of the slider 124. A guide mechanism for the slider is provided between the slider 124 and the two side walls of the gantry frame. The fixing assembly 121 is installed on the end face of the slider 124 near the cutting device 2, and the second drive assembly 122 is installed on the end face of the slider 124 away from the cutting device 2. The output end of the second drive assembly 122 passes through the slider 124 and is connected to the fixing assembly 121.

[0050] Furthermore, a guide rail 14 is provided on at least one side of the first frame 11. The guide rail 14 is parallel to the feeding direction of the quenching tube 10. A guide block 15 is provided at the bottom of the feeding mechanism 12, which slides with the guide rail 14. The movement direction of the feeding mechanism 12 is ensured by the cooperation between the guide block 15 and the guide rail 14.

[0051] Furthermore, such as Figure 3-4As shown, the cutting mechanism 23 further includes a fifth drive assembly 232 for driving the grinding wheel 231 to rotate and a sixth drive assembly 233 for driving the grinding wheel 231 to move up and down. Specifically, the fifth drive assembly 232 can be a drive motor, and the sixth drive assembly 233 can be a drive cylinder.

[0052] Example 2

[0053] This embodiment describes an automatic feeding and cutting method for quenched tubes, which is performed using the automated feeding and cutting equipment for quenched tubes described in any of the embodiments in Example 1. The automated feeding and cutting method includes the following steps:

[0054] S1: The quenched tube 10 to be cut is fixedly installed on the fixing component 121 of the feeding mechanism 12. After installation, the control system controls the first driving component 13 to move, and the first driving component 13 drives the feeding mechanism 12 to move a certain distance in the direction of the cutting device 2.

[0055] S2: After the feeding mechanism 12 is in place, the control system controls the second drive component 122 to move. The second drive component 122 drives the fixed component 121 to rotate. The quenching tube 10 rotates synchronously with the fixed component 121. At the same time, the control system controls the driven detection roller 32 in the cutting detection mechanism 3 to move downward until it contacts the outer surface of the quenching tube 10. The driven detection roller 32 rotates synchronously with the quenching tube 10.

[0056] S3: Next, the control system controls the grinding wheel 231 in the cutting mechanism 23 to cut the quenched tube 10. When the quenched tube 10 is not cut, the quenched tube 10 located on the side of the grinding wheel 231 away from the feeding device 1 still rotates with the fixed component 121. The driven detection pressure roller 32 rotates synchronously, and the detection block 33 also rotates synchronously with the driven detection pressure roller 32. Since the minimum distance between each position on the outer periphery of the detection block 33 and the proximity switch 34 is at least partially different, the proximity switch 34 can continuously detect the signal of distance change. The proximity switch 34 does not send a "cut-off" signal to the control system.

[0057] S4: When the quenching tube 10 is cut off, the quenching tube 10 located on the side of the grinding wheel 231 away from the feeding device 1 cannot rotate with the fixed component 121. The driven detection pressure roller 32 stops rotating synchronously, and the detection block 33 also stops rotating synchronously. At this time, the proximity switch 34 cannot detect the signal of distance change, and the proximity switch 34 sends a "cut-off" signal to the control system.

[0058] S5: When the control system receives the "cut-off" signal, the control system controls the first drive component 13 to move again. The first drive component 13 drives the feeding mechanism 12 to move a certain distance in the direction of the cutting device 2. Steps S2-S5 are repeated in sequence until the quenching tube 10 to be cut on the fixed component 121 is completely cut, realizing the automated feeding and cutting of the quenching tube 10.

[0059] The automatic feeding and cutting method for quenched tubes in this embodiment replaces the through-beam photoelectric sensor in the prior art with a cutting detection mechanism 3. The detection block 33 and proximity switch 34 in the cutting detection mechanism 3 can be set away from the cutting cavity or isolated from the cutting cavity, so that dust, water or other coolant, sand and other impurities generated during the cutting of the quenched tube will not affect the detection of the proximity switch 34, ensuring the accuracy of the cutting detection of the quenched tube, realizing the automatic feeding and cutting of the quenched tube, improving production efficiency and saving labor costs.

[0060] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

8. An automated feeding and cutting method using the automated feeding and cutting equipment for quenched tubes according to any one of claims 1-7, characterized in that: The automated feeding and cutting method includes the following steps: S1: The quenched tube (10) to be cut is fixedly installed on the fixed component (121) of the feeding mechanism (12). After installation, the control system controls the first drive component (13) to move. The first drive component (13) drives the feeding mechanism (12) to move a distance in the direction of the cutting device (2). S2: After the feeding mechanism (12) is in place, the control system controls the second drive component (122) to move. The second drive component (122) drives the fixed component (121) to rotate. The quenching tube (10) rotates synchronously with the fixed component (121). At the same time, the control system controls the driven detection roller (32) in the cutting detection mechanism (3) to move downward until it contacts the outer surface of the quenching tube (10). The driven detection roller (32) rotates synchronously with the quenching tube (10). S3: Then the control system controls the grinding wheel (231) in the cutting mechanism (23) to cut the quenching tube (10). When the quenching tube (10) is not cut, the quenching tube (10) located on the side of the grinding wheel (231) away from the feeding device (1) still rotates with the fixed component (121). The driven detection pressure roller (32) rotates synchronously, and the detection block (33) also rotates synchronously with the driven detection pressure roller (32). Since the minimum distance between each position of the outer periphery of the detection block (33) and the proximity switch (34) is at least partially different, the proximity switch (34) can continuously detect the signal of distance change. The proximity switch (34) does not send a "cut off" signal to the control system. S4: When the quenching tube (10) is cut off, the quenching tube (10) located on the side of the grinding wheel (231) away from the feeding device (1) cannot rotate with the fixed component (121). The driven detection pressure roller (32) stops rotating synchronously, and the detection block (33) also stops rotating synchronously. At this time, the proximity switch (34) cannot detect the signal of distance change, and the proximity switch (34) sends a "cut-off" signal to the control system. S5: When the control system receives the "cut off" signal, the control system controls the first drive component (13) to move again. The first drive component (13) drives the feeding mechanism (12) to move a distance in the direction of the cutting device (2). Steps S2-S5 are repeated in sequence until the quenching tube (10) to be cut on the fixed component (121) is completely cut, so as to realize the automated feeding and cutting of the quenching tube (10).
