Description

Technical Field

[0001] This utility model relates to the field of sleeve equipment, specifically a semi-automatic sleeve insulation pipe device. Background Technology

[0002] The metal connecting pipes used in refrigeration equipment to connect the outdoor and indoor sections need to be wrapped with insulated pipes (usually polyethylene pipes or rubber-plastic foam pipes). Traditionally, the process of fitting insulated pipes to these metal connecting pipes involves manually measuring the required length of the metal pipe, manually cutting the material, manually measuring the required length of the insulated pipe, manually cutting the material, and finally manually fitting the insulated pipe onto the metal connecting pipe. This entire process is laborious, time-consuming, and inefficient. When fitting the insulated pipe onto the metal pipe, as the length of the insulated pipe increases, the friction between the insulated pipe and the metal pipe also increases, making it more difficult and slower to fit. In some cases, after a section of insulated pipe is fitted onto the metal pipe, it may even clump together due to resistance, requiring manual extension and smoothing to continue fitting the remaining insulated pipe. At the same time, due to the twisting and swaying of the insulation pipes, care must be taken at all times when installing the insulation pipes to avoid puncturing the insulation pipes at the ends of the metal pipes. Utility Model Content

[0003] This invention provides a semi-automatic device for installing insulation pipes, which solves the problem of high frictional resistance between metal pipes when manually installing insulation pipes on them in the existing technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A semi-automatic insulation pipe fitting device includes a feeding device, a first linear motion platform, and a core (24); the core (24) is tubular, the core (24) is installed on the first linear motion platform, the first linear motion platform drives the core (24) to perform linear reciprocating motion, and the axial direction of the core (24) is parallel to the linear motion path of the first linear motion platform; The feeding device delivers metal pipes to the core (24) on the first linear motion platform. One end of the core (24) faces the metal pipe delivered by the feeding device, and the other end of the core (24) serves as a sleeve. The sleeve is used to attach one end of the insulation pipe (47). The core (24) is coaxial with the metal pipe delivered by the feeding device. The core (24) is also provided with several air passages in the tube wall. One end of each air passage is provided as an air outlet on the end face of the sleeve of the core (24), and the other end of each air passage is provided as an air inlet on the outer circumferential side of the core (24). An inflation device is provided at one side of the first linear motion platform. When the core (24) moves to the position of the first linear motion platform corresponding to the inflation device, the inflation device supplies air to each air passage in the core (24) through the air inlet of each air passage.

[0005] Furthermore, in the core (24), the air inlets of each air passage are respectively located on the same circumferential direction on the outer side of the core (24). A sealing ring (25) is installed on the outer side of the core (24) corresponding to the circumferential position. An air nozzle is installed on the sealing ring (25). One end of the air nozzle is used to connect to the inflation device, and the other end of the air nozzle is connected to the air inlet of each air passage in the core (24) through the air hole in the sealing ring (25).

[0006] Furthermore, a claw (26) is rotatably installed on the outer circumferential side of the core (24) near the sleeve interface, and the insulated pipe (47) sleeved to the core (24) is clamped by the claw (26).

[0007] Furthermore, a first cutting device is provided on the side of the first linear motion platform. The first cutting device is used to cut the entire pipe after the metal pipe is inserted into the heat insulation pipe (47).

[0008] Furthermore, a second cutting device is provided on the side of the first linear motion platform, which is used to cut the heat-insulating pipe (47) sleeved on the core (24).

[0009] Furthermore, it also includes a clamshell cylinder located on the side of the first linear motion platform, wherein the cylinder axis is parallel to the linear motion path of the first linear motion platform, and one end of the cylinder opening faces the metal pipe being conveyed by the feeding device. The cylinder includes a cylindrical bottom (11) and a cylindrical cover (12), both of which are semi-cylindrical. The cylindrical bottom (11) and the cylindrical cover (12) are rotatably connected on one side by a hinge (13), thereby allowing the cylindrical cover (12) to be closed on the cylindrical bottom (11), and when the cylindrical cover (12) is closed on the cylindrical bottom (11), there is a gap between the other side of the cylindrical cover (12) and the cylindrical bottom (11); The core (24) is housed in the cylinder, and the first linear motion platform is connected to the core (24) through a bracket (20) that passes through the gap between the cylinder cover (12) and the bottom of the cylinder (11).

[0010] When this utility model is in operation, a plug is inserted into the end of the metal pipe facing the core, and the end of the insulation pipe is manually fitted onto the sleeve of the core away from the metal pipe. At this time, the air outlet of each air passage in the core is connected to the inside of the insulation pipe.

[0011] Next, the first linear motion platform drives the core to move towards the end corresponding to the inflation device until the core and inflation device are aligned. Then, the feeding device feeds the metal tube into the core but not into the insulation tube. Furthermore, the second cutting device cuts the insulation tube fitted onto the core, leaving the designed length of insulation tube at the core's fitting interface. After cutting, a cap is inserted into the end of the insulation tube away from the core.

[0012] At this point, the inflation device supplies air into the insulation pipe through the various air channels of the core. Since the end of the metal pipe facing the core is sealed with a plug, the gas entering the insulation pipe will not flow into the metal pipe through the core; the gas can only continuously enter the insulation pipe. Furthermore, because the end of the insulation pipe away from the core is also sealed with a plug, the interior of the insulation pipe is approximately sealed.

[0013] Subsequently, the metal tube continues to be pushed through the core and gradually penetrates into the insulation tube by the feeding device. During the tube insertion process, since the air outlets of each air passage in the core are located on the end face of the core's sleeve interface, the airflow entering the insulation tube will form an air film between the metal tube and the insulation tube. This air film can cause the insulation tube to expand radially, and it can also reduce the frictional resistance between the metal tube and the insulation tube, thereby allowing the metal tube to smoothly penetrate into the insulation tube.

[0014] When the metal pipe is inserted into the insulation pipe to the designed length, that is, when the end of the metal pipe with the plug is aligned with the end of the insulation pipe with the plug, the end of the metal pipe with the plug pushes out the plug of the corresponding end of the insulation pipe. At this point, the inflation device stops working, and the first cutting device cuts the insulation pipe and the metal pipe together at the position corresponding to the core sleeve interface. After cutting, a metal pipe with the insulation pipe sleeved on the outside is obtained. Then, the plug in the metal pipe is removed, and the finished product is obtained, completing this sleeve operation.

[0015] Finally, reset the feeding device and the core, and manually remove the remaining insulation pipe end from the core's sleeve interface to proceed with the next sleeve operation.

[0016] Compared with existing technologies, this utility model can automatically measure and cut metal pipes and insulation pipes according to the required length, realizing a semi-automatic function of fitting insulation pipes onto metal pipes. It can replace most manual operations, with the advantages of saving time and labor, high efficiency, and good product quality. The sealing ring and air passage on the core can realize radial air intake and axial air exhaust, ensuring that there is always an air film between the metal pipe and the insulation pipe during the pipe insertion process, which greatly reduces the resistance during the pipe insertion process and improves the pipe insertion speed.

[0017] Furthermore, because the clamshell shell provides a stable binding effect, the insulated pipe will not swing or twist after inflation, thus preventing it from being punctured by the metal pipe during the installation process. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-10 As shown in the figure, this embodiment discloses a semi-automatic insulation pipe fitting device, including a feeding device, a first linear motion platform, a clamshell cylinder, a core 24, an air filling device, a first cutting device, and a second cutting device.

[0032] The first linear motion platform is a screw-slider mechanism, comprising a first guide rail 21, a first motor 18, a first screw 19, a first slider, a first limit switch A23, and a first limit switch B22. The first guide rail 21 is fixed to the ground or a support platform and extends horizontally in the front-to-back direction. The first slider is slidably mounted on the first guide rail 21. The first limit switch A23 is located outside the front end of the first guide rail 21, and the first limit switch B22 is located outside the rear end of the first guide rail 21. The first motor 18 is located outside the front end of the first guide rail 21. The first screw 19 is rotatably mounted above the first guide rail 21, and the axis of the first screw 19 is horizontal in the front-to-back direction. The first slider is assembled to the first screw 19 through a central threaded hole. When the first motor 18 drives the first screw 19 to rotate, the first slider performs a linear reciprocating motion in the horizontal front-to-back direction on the first guide rail 21, and the first limit switches A23 and B22 detect whether the first slider has reached the limit position of the linear motion.

[0033] The clamshell cylinder is mounted on the left side of the first linear motion platform via support legs. The cylinder's axial direction is horizontal, meaning it is parallel to the linear motion path of the first slider on the platform. The cylinder's front and rear ends are both openings.

[0034] The cylinder body is composed of a cylinder bottom 11 and a cylinder cover 12, both of which are semi-cylindrical and have horizontal axes in the front and rear directions. The left side of the cylinder bottom 11 and the cylinder cover 12 are rotatably connected by a hinge 13, so that the cylinder cover 12 can be closed on the cylinder bottom 11, and there is a gap between the right side of the cylinder cover 12 and the cylinder bottom 11 when the cylinder cover 12 is closed on the cylinder bottom 11.

[0035] A flared opening 43 is coaxially provided at the rear end of the cylinder, and the flared opening 43 is fixed to the bottom 11 of the cylinder. A straight opening is provided on the radial left side of the flared opening 43, the right end of the straight opening is connected to the inside of the flared opening, and the left end of the straight opening faces outward to the left side of the flared opening 43. Several rotary drive devices are located on the left side of the cylinder. Each rotary drive device includes a rotary drive motor 17, a worm gear 16, a worm wheel 15, and a connecting rod 14. The drive motor 17 is axially horizontal. One end of the worm gear 16 is fixedly connected to the output shaft of the drive motor 17, and the worm wheel 15 is axially horizontal. The worm gear 16 and the worm wheel 15 are connected by a transmission connection. One end of the connecting rod 14 is connected to one side of the worm wheel 15, and the other end of the connecting rod 14 is connected to the cylinder cover 12 of the cylinder.

[0036] When the drive motor 17 drives the worm gear 16 to move linearly in the left and right horizontal direction, the worm wheel 15 rotates, which in turn drives the cylinder cover 12 in the cylinder to close to the bottom 11 of the cylinder through the connecting rod 14, or the cylinder cover 12 opens from the cylinder 11.

[0037] The core 24 is tubular, and its axial direction is horizontal. The core 24 is coaxially arranged inside the cylinder. The axial rear end of the core 24 serves as a sleeve interface for the axial front end of the insulation pipe 47 to be sleeved.

[0038] The core 24 also has several air passages in its tube wall. One end of each air passage serves as an air outlet on the end face around the sleeve of the core 24, while the other end serves as an air inlet on the outer circumferential side of the core 24. Furthermore, the air inlets of each air passage are located on the same circumferential direction on the outer circumferential side of the core 24. A sealing ring 25 is fitted around the outer circumferential side of the core 24 at the corresponding circumferential position. An air nozzle is mounted on the sealing ring 25. One end of the air nozzle is used to connect to an inflation device, and the other end of the air nozzle communicates with the air inlets of each air passage in the core 24 through an air hole in the sealing ring 25.

[0039] Several locking claws 26 are provided on the outer circumferential side of the core 24 near the sleeve interface. One end of each locking claw 26 is rotatably connected to the outer circumferential side of the core 24 via a rotating shaft perpendicular to the axis of the core 24. The other end of each locking claw 26 extends outward from the core 24. Each locking claw 26 can be rotated to fit tightly against the core 24 and can also unfold from the core 24. A torsion spring 27 is respectively fitted on the corresponding rotating shaft on the outer circumferential side of the core 24 for each locking claw 26. One end of the torsion spring 27 is fixed to the corresponding rotating shaft, and the other end is fixed to the outer circumferential side of the core 24. The insulating pipe 47 sleeved on the sleeve interface of the core 24 is secured by the locking claws 26.

[0040] A first support 20 is fixedly connected to the first slider in the first linear motion platform. The first support 20 extends upward and then to the left, passing through the gap between the right side of the cylinder cover 12 and the cylinder bottom 11 and entering the cylinder body. The first support 20 is fixedly connected to the right side of the core 24. When the first slider in the first linear motion platform moves horizontally in the back-and-forth direction, it can drive the core 24 to move horizontally in the back-and-forth direction along the cylinder body.

[0041] A receiving tube 10 is provided outside the front of the axial front end opening of the cylinder body. The receiving tube 10 is coaxial with the cylinder body and has the same inner and outer diameters. There is a gap between the axial rear end opening of the receiving tube 10 and the axial front end opening of the cylinder body. In addition, there is a gap on the right side of the receiving tube extending horizontally in the front-rear direction. This gap is on the same straight line as the gap between the cylinder cover 12 and the right side of the cylinder bottom 11.

[0042] In the first linear motion platform, the front end of the first guide rail 21 extends forward beyond the axial front opening of the receiving cylinder 10, and the rear end of the first guide rail 21 extends backward beyond the axial rear opening of the cylinder or is flush with the axial rear opening of the cylinder. Therefore, in the first linear motion platform, the forward limit position of the first slider can exceed the axial front opening of the receiving cylinder 10, and the rearward limit position of the first slider can exceed the axial rear opening of the cylinder or correspond to the position of the axial rear opening of the cylinder.

[0043] The feeding device is located outside the front end of the axial front end of the receiving cylinder 10. The feeding device includes a second linear motion platform, a first electromagnetic sleeve 5, and a second electromagnetic sleeve 9.

[0044] The second linear motion platform in the feeding device includes a second guide rail 4, a second motor 1, a second screw 2, a second slider, a second limit switch A6, and a second limit switch B7. The second guide rail 4 is located on the ground or support platform in front of the axial front end of the receiving cylinder 10, and extends horizontally in the front-back direction. The second slider is slidably mounted on the second guide rail 4. The second limit switch A6 is located outside the front end of the second guide rail 4, and the second limit switch B7 is located outside the rear end of the second guide rail 4. The second screw 2 is axially horizontal in the front-back direction and is rotatably mounted above the second guide rail 4. The output shaft of the second motor 1 is coaxially fixedly connected to the axial front end of the second screw 2, and the second slider is assembled to the second screw 2 through a threaded through-hole. When the second motor 1 drives the second screw 2 to rotate, the second slider performs a linear reciprocating motion in the front-back horizontal direction on the second guide rail 4, and the second limit switches A6 and B7 can detect whether the second slider has reached the limit position of the linear motion.

[0045] The first electromagnetic sleeve 5 is fixed to the second slider of the second linear motion platform by the second bracket 3, thereby the first electromagnet 5 moves linearly with the second slider. The first electromagnetic sleeve 5 includes a circular sleeve with an axially horizontal front-to-back direction. Several electromagnets are embedded and fixed in the inner wall of the circular sleeve. The inner diameter of the circular sleeve matches the outer diameter of the metal tube 48, and the circular sleeve is coaxial with the core 24.

[0046] The second electromagnetic sleeve 9 is fixed above the ground or support platform between the second linear motion platform and the axial front end opening of the storage cylinder 10 via the third bracket 8. The structure of the second electromagnet 9 is the same as that of the first electromagnet 5, both including a circular sleeve with an axially horizontal front-back direction, and several electromagnets embedded in the inner wall of the circular sleeve, and the circular sleeve is coaxial with the core 24.

[0047] The metal tube 48 passes through the circular sleeves of the first electromagnetic sleeve 5 and the second electromagnetic sleeve 9 and extends towards the axial front end of the receiving cylinder 10. The electromagnet in the first electromagnetic sleeve 5 is energized to attract and fix the metal tube 48, while the electromagnet in the second electromagnetic sleeve 9 is de-energized. If the second slider in the second linear motion platform moves backward at this time, the first electromagnetic sleeve 5 moves backward accordingly, thereby conveying the metal tube 48 towards the receiving cylinder 10 and the cylindrical section. When the tube is in place, both the electromagnets in the first electromagnetic sleeve 5 and the second electromagnetic sleeve 9 are energized to attract and fix the metal tube 48, thus achieving fixation of the metal tube 48.

[0048] The inflation device is located at the left front of the axial front end of the storage cylinder 10. The inflation device includes a first cylinder 28, whose air port is connected to an external air source via a drive solenoid valve 29. The piston rod of the first cylinder 28 extends horizontally to the right towards the axial front end of the storage cylinder 10, and an inflation nozzle 30 is inserted into the end of the piston rod. A guide sleeve 32, axially horizontal in the left-right direction, is fixed between the inflation device and the storage cylinder 10. The portion of the inflation nozzle 30 outside the piston rod of the first cylinder 28 passes through the guide sleeve 32. An inflation hose 34 is connected to the air inlet of the inflation nozzle 30 inside the piston rod of the first cylinder 28. The inflation hose 34 extends out of the piston rod of the first cylinder 28 and is connected to an external air source via an inflation solenoid valve 33. The end of the inflation nozzle 30 facing the storage cylinder 10 is the air outlet, and a sealing gasket 31 is installed at the outlet.

[0049] In the inflation device, the first cylinder 28 drives the inflation nozzle 30 to perform a linear reciprocating motion in the left and right horizontal direction, and the guide sleeve 32 plays a guiding role. An external air source supplies air to the air inlet of the inflation nozzle 30, and finally the gas flows out from the air outlet of the inflation nozzle 30.

[0050] The first cutting device is located outside the left side of the cylinder and is close to the axial front end of the cylinder opening. The first cutting device includes a third linear motion platform, a cutting motor 39, a cutting blade 40, a protective cover 41, and a third limit switch 42.

[0051] The third linear motion platform includes a third guide rail 37, a third motor 35, a third screw 36, a third slider, and a fourth bracket 38. The third guide rail 37 is fixed to the ground or support platform outside the left side of the cylinder, and extends horizontally in the left-right direction. The third slider is slidably mounted on the third guide rail 37. The third screw 36 is axially horizontal in the left-right direction and is rotatably mounted behind the third guide rail 37. The output shaft of the third motor 35 is coaxially connected to the left end of the third screw 36. The fourth bracket 38 is assembled to the third screw 36 through a threaded through-hole, and the fourth bracket 38 is fixedly connected to the third slider. When the third motor 35 drives the third screw 36 to rotate, it can drive the third slider to perform linear reciprocating motion in the left-right horizontal direction on the third guide rail 37.

[0052] The third limit switch 42 is fixed outside the right end of the third guide rail 37 and is used to detect whether the third slider has moved to the limit position.

[0053] The cutting motor 39 is fixed to the third slider of the third linear motion platform and reciprocates in a horizontal linear motion with the third slider. The axis of the cutting motor 39 is horizontal in the front-back direction. The cutting blade 40 is a circular cutting blade, which is coaxially fixed to the output shaft of the cutting motor 39. The cutting blade 40 is located outside the left side of the gap between the rear end opening of the receiving cylinder 10 and the front end opening of the cylinder body. The protective cover 41 is fixed to the cutting motor 39, covers the cutting blade 40, and has a notch on the right side to expose the right side of the cutting blade 40.

[0054] When the third slider moves to the right, the cutting motor 39 and the cutting blade 40 can move together towards the storage cylinder 10 and the cylinder body. When the right side of the cutting blade 40 moves to the gap between the rear end of the storage cylinder 10 and the front end of the cylinder body, if the cutting motor 39 drives the cutting blade 40 to rotate, the object in the gap can be cut.

[0055] The second cutting device is located outside the left side of the flared opening 43 at the rear end of the cylinder. The second cutting device includes a cutting cylinder 45, a blade 44, and a solenoid valve 46. The cutting cylinder 45 is fixed outside the left side of the flared opening 43, and its axial direction is horizontal. The cutting cylinder 45 is connected to an external air source via the solenoid valve 46. The piston rod of the cutting cylinder 45 points horizontally to the right towards the left end of the straight opening radially to the left of the flared opening 43. The blade 44 is a straight blade, with one end fixed to the end of the piston rod of the cutting cylinder 45. The blade 44 is sized to be able to extend into the straight opening radially to the left of the flared opening 43. When the cutting cylinder 45 drives the blade 44 to move to the right until it passes through the straight opening and enters the flared opening 43, it can cut the object inside the flared opening 43.

[0056] like Figure 11 , Figure 12 As shown, initially, in this embodiment, the first support 20 is located at the rear end of the first guide rail 21 in the first linear motion platform, thereby placing the core 24 at the rear end of the cylinder. The axial rear end of the core 24 passes through the flared opening 43 and exits from the large-diameter end of the flared opening 43. Furthermore, the cylinder cover is placed on the bottom of the cylinder, and the gap between the cylinder cover and the right side of the cylinder allows the first support 20 to pass through. Similarly, the gap on the right side of the storage cylinder 10 also allows the first support 20 to pass through.

[0057] During operation, the insulating pipe 47 is positioned horizontally along its axial direction, and the axial front end of the insulating pipe 47 is fitted onto the axial rear end of the core 24, i.e., the sleeve. Then, the core 24 is driven forward by the first linear motion platform. In the initial stage of the core 24's forward movement, the claws 26 on the outer circumference of the core 24 are abutted by the large-diameter end of the flared end 43, causing the claws 26 to rotate and retract towards the core 24, gripping the insulating pipe 47 as they retract. The core 24 continues to move forward, causing the entire core 24 to move along the inside of the cylinder, and the insulating pipe 47 fitted onto the core 24 gradually enters the cylinder. The first linear motion platform stops moving when the axial front end of the core 24 protrudes from the axial front end of the receiving cylinder 10, and the axial rear end of the core 24 enters the receiving cylinder 10 and is located in front of the gap between the receiving cylinder 10 and the cylinder.

[0058] At this point, a certain length of insulated pipe 47 has passed through the flared opening 43 and entered the cylinder. Then, the second cutting device is activated, and the cutting cylinder 45 drives the blade 44 into the flared opening 43 from the straight opening on the left side, cutting the portion of the insulated pipe 47 inside the flared opening 43. Combined with manual rotation of the insulated pipe 47, the portion of the insulated pipe 47 located inside the flared opening is broken off, forming the axial rear end of the insulated pipe 47. A plug is then inserted into the axial rear end of the insulated pipe 47. The second cutting device is reset after cutting is completed.

[0059] Next, a plug is inserted into the rear end of the metal tube 48 on the feeding device, and the metal tube 48 is conveyed backward by the feeding device until the rear end of the metal tube 48 passes through the front end of the core 24 but does not reach the position of the sealing ring 25. At this time, the first cylinder 28 in the inflation device drives the inflation nozzle 30 to move towards the nozzle of the sealing ring 25 on the core 24 until the outlet of the inflation nozzle 30 is sealed to the nozzle of the sealing ring 25 through the sealing gasket 31. Then, the external air source supplies air to the various air passages in the core 24 through the inflation nozzle 30 and the nozzle of the sealing ring 25. Since the air outlets of each air passage of the core 24 are located at the end face of the sleeve port of the core 24, and the sleeve port of the core 24 is connected to the axial front end of the insulation pipe 47, and the axial rear end of the insulation pipe 47 is plugged with a cap, and the axial rear end of the metal pipe 48 entering the core 24 is also plugged with a cap, the core 24 and the insulation pipe 47 form an almost sealed structure. The airflow from each air passage of the core 24 continuously enters the insulation pipe 47, thereby achieving air inflation into the insulation pipe 47. Furthermore, since the insulation pipe is located inside the closed cylinder, the insulation pipe 47 will not swing or twist during inflation due to the restraint effect of the cylinder, thus preventing it from being punctured by the metal pipe 48 during subsequent pipe insertion.

[0060] When the inflation device is activated, the feeding device continues to convey the metal tube 48 backward, allowing it to pass through the core 24 and gradually penetrate into the insulation tube 47, thus achieving tube insertion. During the insertion process, because the insulation tube 47 is filled with gas, a circumferential gas film is formed between the inner wall of the insulation tube 47 and the outer wall of the metal tube 48. This gas film allows the insulation tube to expand slightly in the radial direction and reduces the frictional resistance between the metal tube 48 and the insulation tube 47, thereby enabling the metal tube 48 to smoothly penetrate into the insulation tube 47.

[0061] When the metal pipe 48 is inserted until its axial rear end is flush with the axial rear end of the insulation pipe 47, the axial rear end of the metal pipe 48 pushes out the plug inside the axial rear end of the insulation pipe 47. At this time, the inflation device closes and resets, and the first cutting device operates. The third linear motion platform in the first cutting device drives the cutting motor 39 and the cutting blade 40 to move to the right, so that the right side of the cutting blade 40 enters the gap between the axial rear end of the receiving cylinder 10 and the axial front end of the cylinder body. Then, the cutting motor 39 drives the cutting blade 40 to rotate, and in conjunction with the rightward feed motion, the cutting blade 40 cuts the metal pipe 48 and the insulation pipe 47 together in the gap between the receiving cylinder 10 and the cylinder body. After cutting, the metal pipe 48 with the insulation pipe 47 wrapped around it remains inside the cylinder body. After cutting, the first cutting device resets.

[0062] After cutting, the cylinder cover 12 is opened from the bottom 11 of the cylinder, allowing the metal pipe 48 with the insulating material to be removed. The plug inserted into the axial rear end of the metal pipe 48 is also removed, resulting in the finished product and completing this sleeve operation. Then, the remaining portion of the insulating material 47 at the sleeve joint of the core 24 is removed. The core 24 is reset via the first linear motion platform, and the feeding device is also reset, allowing for another sleeve operation.
