Description

Technical Field

[0001] The invention relates to the field of automatic cutting equipment, in particular to automatic feeding and cutting equipment for quenching tubes. Background Art

[0002] In the process of automatic fixed-length cutting of long workpieces such as steel bars and pipes, it is necessary to set up a detection mechanism to detect whether the workpiece is completely cut, so as to determine whether the next feeding can be carried out based on the detection result. In the prior art, a photoelectric sensor of the opposite beam type is often used to sense whether the workpiece is cut; for example, Chinese utility model patent CN219634495U discloses a large-diameter pipe uncut detection device based on a pressure-feeding mechanism, which can realize the traction, cutting and pressure-feeding of the pipe after cutting by setting the pipe traction mechanism, cutting detection mechanism and pressure-feeding mechanism, wherein the cutting detection mechanism includes a corresponding opposite beam grating, which can detect whether the pipe cutting is completed, so as to avoid the pipe surface damage and the damage of the rear-end automatic detection and packaging device due to the pipe not being cut during the extrusion production process.

[0003] Since the quenching tube has the characteristic of high hardness, water or other coolants need to be added for cooling during the cutting process. The quenching tube will produce dust, water or other coolants, sand and other substances during the cutting process, resulting in a relatively harsh environment of the entire cutting chamber. Therefore, it is difficult to sense whether the quenching tube is cut using the through-beam photoelectric sensor in the prior art, and it is easy to make a misjudgment, thereby affecting the automatic feeding and cutting of the quenching tube.

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

[0008] The cutting device is arranged at the discharge end of the feeding device, and the cutting device comprises a second frame, and a cutting mechanism for cutting the quenching tube is arranged on the second frame, and the cutting mechanism comprises a grinding wheel;

[0009] The cutting detection mechanism includes a driven detection pressure wheel, a detection block and a proximity switch, the driven detection pressure wheel is rotatably arranged 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 pressure wheel, the proximity switch is arranged opposite to the outer peripheral side surface of the detection block, the driven detection pressure wheel can contact the surface of the quenching tube and the quenching tube can drive the driven detection pressure wheel and the detection block to rotate, and the minimum distance between each position of the outer peripheral side surface of the detection block and the proximity switch is at least partially different.

[0010] Furthermore, the cut-off detection mechanism includes a bracket, and both ends of the driven detection pressure wheel are rotatably connected to the bracket via a rotating shaft, one of the rotating shafts extends to the outside of the bracket and is fixedly connected to the detection block, and the proximity switch is fixed on the bracket.

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

[0012] Furthermore, a protective cover is provided on a side of the bracket close to the detection block, and the detection block and the proximity switch are both arranged in the protective cover.

[0013] Furthermore, the cut-off detection mechanism also includes a third driving component, the third driving component is connected to the bracket, and the third driving component is used to drive the bracket to move away from or close to the quenching tube.

[0014] Furthermore, the cutting device also includes a bearing mechanism arranged on the second frame for supporting the quenching tube, and the bearing mechanisms are two and are respectively located on both sides of the grinding wheel; the bearing mechanism includes a supporting base and two supporting rollers rotatably arranged on the supporting base.

[0015] Furthermore, the cutting device also includes a bearing plate for placing the quenching tube, two ends of the bearing plate are respectively arranged on the two bearing mechanisms, and two supporting rollers in the bearing mechanisms pass through the bearing plate to contact the quenching tube.

[0016] Furthermore, the feeding mechanism also includes a supporting seat, a slider is slidably arranged in the supporting seat, the fixing assembly and the second driving assembly are both arranged on the slider, and a fourth driving assembly for driving the slider to move up and down is arranged on the supporting seat.

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

[0018] On the other hand, the present invention further provides a method for automatically feeding and cutting a quenching tube, which is performed using the automatic feeding and cutting device for quenching tubes described in any of the above embodiments; the automatic feeding and cutting method comprises the following steps:

[0019] S1: The quenching tube to be cut is fixedly installed on the fixed component of the feeding mechanism. After installation, the control system controls the first driving component to move, and the first driving 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 driving assembly to move, the second driving assembly drives the fixed assembly to rotate, and the quenching tube rotates synchronously with the fixed assembly. At the same time, the control system controls the driven detection pressure wheel in the cut-off detection mechanism to move downward until it contacts the outer surface of the quenching tube, and the driven detection pressure wheel rotates synchronously with the quenching tube;

Since the minimum distance between each position of the outer peripheral side of the detection block and the proximity switch is at least partially different, at this time, the proximity switch can continuously detect the signal of distance change, and 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 wheel 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 assembly to move again, and the first drive assembly 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 quenching tubes to be cut on the fixed assembly are cut, thereby realizing the automatic feeding and cutting of the quenching tube.

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

[0025] By arranging a driven detection pressure wheel capable of contacting the surface of the quenching tube in the cutting detection mechanism, and one end of the driven detection pressure wheel is fixedly connected to the detection block, the driven detection pressure wheel is arranged on the side of the grinding wheel away from the feeding device. When the grinding wheel does not completely cut the quenching tube, the quenching tube located on the side of the grinding wheel away from the feeding device still follows the fixed component to rotate, and can drive the driven detection pressure wheel and the detection block to rotate synchronously. Since the minimum distance between each position of the outer peripheral side of the detection block and the proximity switch is at least partially different, at this time, the proximity switch can continuously detect the distance 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, and the driven detection pressure wheel and the detection block stop rotating synchronously. At this time, the proximity switch cannot detect the distance change signal, and it is judged that the cut finished product part has been completely cut off, and the proximity switch 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 to feed the next cutting, thereby realizing the automatic feeding and cutting of the quenching tube. By setting a cut-off detection mechanism instead of the corresponding photoelectric sensor in the prior art, the detection block and the proximity switch in the cut-off detection mechanism can be set away from the cutting cavity or can be isolated from the cutting cavity, so that the dust, water or other coolants, sand and other impurities generated during the quenching tube cutting process will not affect the detection of the proximity switch, ensuring the accuracy of the quenching tube cut-off detection, realizing the automatic feeding and cutting of the quenching tube, improving production efficiency, and saving labor costs.

DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0036] Example 1

[0037] like Figures 1 to 7 As shown, the present embodiment provides an automatic feeding and cutting device for quenching tubes, comprising a control system (not shown in the figure), a feeding device 1, a cutting device 2 and a cutting detection mechanism 3, wherein the feeding device 1, the cutting device 2 and the cutting detection mechanism 3 are respectively connected to the control system;

[0038] The feeding device 1 includes a first frame 11, on which a feeding mechanism 12 and a first driving assembly 13 are provided, the first driving assembly 13 is used to drive the feeding mechanism 12 to move forward and backward along the first frame 11, and the feeding mechanism 12 includes a fixing assembly 121 for fixing the quenching tube 10 and a second driving assembly 122 for driving the fixing assembly 121 to perform rotational motion;

[0039] The cutting device 2 is arranged at the discharge end of the feeding device 1, and the cutting device comprises a second frame 21, and a cutting mechanism 23 for cutting the quenching tube 10 is arranged on the second frame 21, and the cutting mechanism 23 comprises a grinding wheel 231;

[0040] The cutting detection mechanism 3 includes a driven detection pressure wheel 32, a detection block 33 and a proximity switch 34. The driven detection pressure wheel 32 is rotatably arranged 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 wheel 32. The proximity switch 34 is arranged opposite to the outer peripheral side surface of the detection block 33. The driven detection pressure wheel 32 can contact the surface of the quenching tube 10 and the quenching tube 10 can drive the driven detection pressure wheel 32 and the detection block 33 to rotate. The minimum distance between each position of the outer peripheral side surface of the detection block 33 and the proximity switch 34 is at least partially different.

[0041] Specifically, the first driving assembly 13 may include a servo motor and a transmission gear arranged on the feeding mechanism 12, the output end of the servo motor is drivingly connected to the transmission gear, and a rack meshing with the transmission gear is arranged 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 forward and backward on the first frame 11; of course, in some other embodiments, the first driving assembly 13 can also adopt a driving mechanism such as a telescopic cylinder, a motor screw nut, etc. ; The second driving component 122 can be a driving motor, which is connected to the fixed component by driving. The driving motor drives the fixed component 121 to rotate, thereby driving the quenching tube 10 to rotate; the fixed component 121 can adopt an inclined wedge-type internal support clamping mechanism, and the inclined wedge-type internal support clamping mechanism is inserted into the interior of one end of the quenching tube 10. The driving member in the inclined wedge-type internal support clamping mechanism drives the inclined 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 clamp.

[0042] In this embodiment, since the quenching tube 10 will rotate during the cutting process, a driven detection pressure wheel 32 capable of contacting the surface of the quenching tube 10 is provided in the cutting detection mechanism 3, and one end of the driven detection pressure wheel 32 is fixedly connected to the detection block 33, and the driven detection pressure wheel 32 is arranged 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, wherein the part away from the feeding device 1 is the cut product part, and the part close to the feeding device 1 is the main body, that is, the driven detection pressure wheel 32 contacts the surface of the cut product part, when the grinding wheel 231 does not completely cut the cut product part from the main body, driven by the fixing component 121, the cut product part will rotate with the main body, and the cut product part can drive the driven detection pressure wheel 32 to rotate while rotating, and the detection block 33 also follows the driven detection pressure wheel 32 The rotation movement is performed synchronously. Since the minimum distance between each position of the outer peripheral side surface of the detection block 33 and the proximity switch 34 is at least partially different, at this time, the proximity switch 34 can continuously detect the signal of distance change, and the proximity switch 34 does not send a "cut-off" signal to the control system; when the cut finished product part is completely cut off, that is, the cut finished product part is separated from the main body, the cut finished product part cannot rotate with the main body, and the driven detection pressure wheel 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, then it is judged that the cut finished product 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 next cutting, thereby realizing the automatic feeding and cutting of the quenching tube 10. By providing a cut-off detection mechanism 3 to replace the beam-type photoelectric sensor in the prior art, the detection block 33 and the proximity switch 34 in the cut-off detection mechanism 3 can be arranged away from the cutting cavity or can be arranged isolated from the cutting cavity, so that dust, water or other coolants, sand and other impurities generated during the quenching tube cutting process will not affect the detection of the proximity switch 34, thereby ensuring the accuracy of the quenching tube cut-off detection, realizing the automatic feeding and cutting of the quenching tube, improving production efficiency and saving labor costs.

[0043] Furthermore, the cut-off detection mechanism 3 includes a bracket 31, and both ends of the driven detection pressure wheel 32 are rotatably connected to the bracket 31 through a rotating shaft 35, one of the rotating shafts 35 extends to the outside of the bracket 31 and is fixedly connected to the detection block 33, and the proximity switch 34 is fixed on the bracket 31. Specifically, Figure 6-7As shown, a mounting groove is provided through one end of the bracket 31 close to the quenching tube 10, and both ends of the driven detection pressure wheel 32 are connected with a rotating shaft 35. The rotating shaft 35 is rotatably installed in the two side walls of the mounting groove through bearings, wherein 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, and the detection block 33 is installed on the end of the rotating shaft 35 away from the bracket 31. Such a configuration, on the one hand, facilitates the driven detection pressure wheel 32 to drive the detection block 33 to rotate, and on the other hand, the detection block 33 and the proximity switch 34 can be set away from the grinding wheel 231, thereby reducing the influence of impurities generated during the cutting process on the detection block 33 and the proximity switch 34.

[0044] Furthermore, if 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 of the annular portion 332, and 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 of the annular portion 332, the minimum distance between each position of the outer circumferential side of the detection block 33 and the proximity switch 34 can be 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 is cut off. Of course, in other embodiments, the detection block 33 can also adopt other shapes, such as gear shape, elliptical shape, etc.

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

[0046] Furthermore, if Figure 4 and 6As shown, the cut-off detection mechanism 3 further includes a third driving assembly 37, which is connected to the bracket 31, and is used to drive the bracket 31 away from or close to the quenching tube 10. Specifically, the cut-off detection mechanism 3 further includes a mounting seat 38, which is fixedly connected to one side of the bearing mechanism 22, and the third driving assembly 37 can be a driving cylinder, the output end of the driving cylinder is rotatably connected to a driving connection block 30, and the end of the driving connection block 30 away from the driving cylinder is fixedly connected to a transmission shaft 39, the transmission shaft 39 is arranged parallel to the central axis of the driven detection pressure wheel 32, and the transmission shaft 39 is rotatably connected to the mounting seat 38, and the end of the bracket 31 away from the mounting groove is installed on the transmission shaft 39; when the output end of the driving cylinder performs telescopic movement, it will drive the driving connection 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 wheel 32 is close to or away from the surface of the quenching tube 10, so that the driven detection pressure wheel 32 can contact the surface of the quenching tube 10.

[0047] Furthermore, if Figure 4-5 As shown, the cutting device 2 also includes a bearing mechanism 22 arranged on the second frame 21 for supporting the quenching tube 10, and the bearing mechanism 22 is two and respectively located on both sides of the grinding wheel 231; the bearing mechanism 22 includes a support base 221 and two support rollers 222 rotatably arranged on the support base 221. In this embodiment, by arranging the bearing mechanism on both sides of the grinding wheel 231, the quenching tube 10 located on both sides of the grinding wheel 231 can be supported during the cutting process of the grinding wheel 231, so as to prevent the quenching tube 10 from bending and deforming due to the force; in addition, the support roller 222 is arranged in the bearing mechanism 22, and during the rotation of the quenching tube 10, the support roller 222 will also rotate with it, so as to reduce the friction resistance between the quenching tube 10 and the bearing mechanism 22, and ensure the normal rotation of the quenching tube 10.

[0048] Furthermore, if Figure 4-5As shown, the cutting device 2 also includes a bearing plate 24 for placing the quenching tube 10, and the two ends of the bearing plate 24 are respectively arranged on the two bearing mechanisms 22, and the two support rollers 222 in the bearing mechanism 22 pass through the bearing plate 24 and contact the quenching tube 10. In this embodiment, by further arranging the bearing plate 24 above the two bearing mechanisms 22, the support effect on the quenching tube 10 is further increased, and when the length of the cut finished part of the quenching tube 10 is less than the distance between the two bearing mechanisms 22, when the end of the cut finished section away from the grinding wheel 231 cannot be supported on the bearing mechanism 22, the cut finished section can be supported by the bearing plate 24, thereby increasing the application range of the automatic feeding and cutting equipment for quenching tubes in this embodiment. On this basis, in order to ensure the function of the support roller 222, the bearing plate 24 is penetrated with an opening at the position corresponding to the support roller 222, and the support roller 222 can pass through the opening and contact the quenching tube 10.

[0049] Furthermore, if Figure 3 As shown, the feeding mechanism 12 further includes a support seat 123, a slider 124 is slidably disposed in the support seat 123, the fixing assembly 121 and the second driving assembly 122 are both disposed on the slider 124, and a fourth driving assembly 125 for driving the slider 124 to move up and down is disposed on the support seat 123. In this embodiment, by providing the slider 124 and the fourth driving assembly 125, the height of the fixing assembly 121 can be adjusted according to the diameter of the quenching tube 10 in actual production, so as to adapt to the processing of quenching tubes 10 with different diameters and improve applicability. Specifically, the support seat 123 includes a gantry frame, and the slider 124 is slidably arranged in the gantry frame. The fourth drive component 125 can adopt a drive mechanism such as a drive cylinder, a motor screw nut, etc. The fourth drive component 125 is installed on the top of the support seat 123, and its working end extends downward through the top of the support seat 123 and is connected to the top of the slider 124. A guide mechanism of the slide rail slider is arranged between the slider 124 and the two side walls of the gantry frame. The fixed component 121 is installed on one end face of the slider 124 close to the cutting device 2, and the second drive component 122 is installed on one end face of the slider 124 away from the cutting device 2. The output end of the second drive component 122 passes through the slider 124 and is connected to the fixed component 121.

[0050] Furthermore, a guide rail 14 is provided on at least one side of the first frame 11, and the guide rail 14 is parallel to the feeding direction of the quenching tube 10. A guide block 15 that slides with the guide rail 14 is provided at the bottom of the feeding mechanism 12. 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, if Figure 3-4As shown, the cutting mechanism 23 further includes a fifth driving assembly 232 for driving the grinding wheel 231 to rotate and a sixth driving assembly 233 for driving the grinding wheel 231 to move up and down. Specifically, the fifth driving assembly 232 can be a driving motor, and the sixth driving assembly 233 can be a driving cylinder.

[0052] Example 2

[0053] The automatic feeding and cutting method for quenching tubes in this embodiment is performed by using the automatic feeding and cutting equipment for quenching tubes described in any one of the embodiments in Embodiment 1; the automatic feeding and cutting method comprises the following steps:

[0054] S1: The quenching tube 10 to be cut is fixedly installed on the fixing assembly 121 of the feeding mechanism 12. After installation, the control system controls the first driving assembly 13 to move, and the first driving assembly 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 driving assembly 122 to move, and the second driving assembly 122 drives the fixed assembly 121 to rotate, and the quenching tube 10 rotates synchronously with the fixed assembly 121. At the same time, the control system controls the driven detection pressure wheel 32 in the cutting detection mechanism 3 to move downward until it contacts the outer surface of the quenching tube 10, and the driven detection pressure wheel 32 rotates synchronously with the quenching tube 10;

[0056] 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 following the fixed component 121, the driven detection pressure wheel 32 rotates synchronously, and the detection block 33 also rotates synchronously following the driven detection pressure wheel 32. Since 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, at this time, the proximity switch 34 can continuously detect the signal of the distance change, and 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 wheel 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 the 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, and 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 looped in sequence until all the quenching tubes 10 to be cut on the fixed component 121 are cut, thereby realizing the automatic feeding and cutting of the quenching tube 10.

[0059] The automatic feeding and cutting method for quenching tubes in this embodiment, by providing a cutting detection mechanism 3 to replace the beam-type photoelectric sensor in the prior art, the detection block 33 and the proximity switch 34 in the cutting detection mechanism 3 can be arranged away from the cutting cavity or can be arranged in isolation from the cutting cavity, so that dust, water or other coolants, sand and other impurities generated during the quenching tube cutting process will not affect the detection of the proximity switch 34, thereby ensuring the accuracy of the quenching tube cutting detection, realizing the automatic feeding and cutting of the quenching tube, improving production efficiency and saving labor costs.

10. An automated feeding and cutting method using the automated feeding and cutting equipment for quenching tubes according to any one of claims 1 to 9, Features: The automatic feeding and cutting method comprises the following steps: S1: The quenching tube (10) to be cut is fixedly mounted on the fixing assembly (121) of the feeding mechanism (12). After the mounting is completed, the control system controls the first driving assembly (13) to operate, and the first driving assembly (13) drives the feeding mechanism (12) to move a certain distance in the direction of the cutting device (2); S2: After the feeding mechanism (12) is in place, the control system controls the second driving component (122) to move, the second driving component (122) drives the fixed component (121) to rotate, and the quenching tube (10) follows the fixed component (121) to rotate synchronously, and at the same time, the control system controls the driven detection pressure wheel (32) in the cut-off detection mechanism (3) to move downward until it contacts the outer surface of the quenching tube (10), and the driven detection pressure wheel (32) follows the quenching tube (10) to rotate synchronously; 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 follows the fixed component (121) to rotate, the driven detection pressure wheel (32) rotates synchronously, and the detection block (33) also rotates synchronously with the driven detection pressure wheel (32). Since the minimum distance between each position of the outer peripheral side surface of the detection block (33) and the proximity switch (34) is at least partially different, at this time, the proximity switch (34) can continuously detect the signal of distance change, and 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 along with the fixed component (121), the driven detection pressure wheel (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 the 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 operate again, and 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 fixing component (121) is completely cut, thereby realizing the automatic feeding and cutting of the quenching tube (10).
