Description

Technical Field

[0001] The present invention relates to the field of metal hose cutting, and specifically relates to a metal hose cutting device. Background Art

[0002] Metal hoses are important components in the connecting pipelines of modern industrial equipment. Metal hoses are used as wire and cable protection tubes for wires, cables, and automated instrument signals, as well as civil shower hoses. Small-diameter metal hoses are mainly used for protecting the sensing lines of precision optical rulers and industrial sensor lines. Metal hoses need to be cut to different lengths in different scenarios. Manual measurement is time-consuming and laborious. At the same time, during the process of cutting the hose, it is easy to pull the metal wires, resulting in an uneven cutting plane. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is as follows: A metal hose cutting device described in the present invention includes a placement platform. The lower surface of the placement platform is fixedly connected with support legs. The upper surface of the placement platform is fixedly connected with a housing gasket. One end of the housing gasket away from the placement platform is fixedly connected with a device housing. One end of the device housing away from the housing gasket is fixedly connected with a housing cover. A tube placement hole is provided at one end of the housing cover away from the device housing. The upper surface of the housing gasket is fixedly connected with a pulling mechanism. The upper surface of the pulling mechanism is fixedly connected with a lifting mechanism. One end of the lifting mechanism away from the device housing is rotatably connected with a cutting mechanism. One end of the placement platform away from the housing gasket is fixedly connected with a collection box; The pulling mechanism includes a limiting mechanism, and a magnetic attraction mechanism is slidably connected to the inner surface of the limiting mechanism; The limiting mechanism includes a hanging plate one. One end of the hanging plate one away from the device housing is fixedly connected with a support plate one. One end of the support plate one away from the hanging plate one is fixedly connected with an arc shell. The upper surface of the arc shell is fixedly connected with an upper limiting plate. One end of the arc shell away from the upper limiting plate is fixedly connected with a lower limiting plate. The upper surface of the lower limiting plate is fixedly connected with a first telescopic spring. One end of the first telescopic spring away from the lower limiting plate is fixedly connected with a fixed block. The first telescopic spring pushes the fixed block to contact the lower surface of the sliding ring, thereby fixing the position of the metal hose. The upper limiting plate above also limits the upward movement distance of the sliding ring, thereby preventing the sliding ring from falling out of the device.

[0004] Preferably, the magnetic attraction mechanism includes a sliding ring. A support bar is fixedly connected to the inner surface of the sliding ring. An electromagnet is fixedly connected to the end of the support bar away from the sliding ring. A first pulling plate is fixedly connected to the lower surface of the sliding ring. A second telescopic spring is fixedly connected to the end of the first pulling plate away from the sliding ring. A second pulling plate is fixedly connected to the end of the second telescopic spring away from the first pulling plate. When the electromagnet is energized, the adsorption force firmly fixes the lower end of the metal hose. The second telescopic spring below the electromagnet pulls the sliding ring downward.

[0005] Preferably, the outer surface of the first hanging plate is fixedly connected to the inner surface of the device housing. The outer surface of the sliding ring is slidably connected to the inner surface of the arc-shaped housing. The lower surface of the second pulling plate is fixedly connected to the upper surface of the housing gasket.

[0006] Preferably, the lifting mechanism includes a first lead screw. The lower surface of the first lead screw is rotatably connected to the upper surface of the first hanging plate. The end of the first lead screw away from the first hanging plate is rotatably connected to a second support plate. A second hanging plate is fixedly connected to the outer surface of the second support plate. A first servo motor is fixedly connected to the end of the second support plate away from the first lead screw. A sliding piece is rotatably connected to the outer surface of the first lead screw. A groove block is fixedly connected to the outer surface of the sliding piece. The first servo motor drives the rotation of the first lead screw, so that the sliding piece drives the groove block to move along the direction of the lead screw, thereby driving the movement of the cutting mechanism, enabling the staff to control the cutting length and reducing the manual measurement process.

[0007] Preferably, the cutting mechanism includes a rotary cutting mechanism. A knocking mechanism is fixedly connected to the upper surface of the rotary cutting mechanism. A grinding and cleaning mechanism is fixedly connected to the inner surface of the rotary cutting mechanism.

[0008] Preferably, the rotary cutting mechanism includes a rotary disc. A fixing piece is fixedly connected to the inner surface of the rotary disc. A first fixing plate is fixedly connected to the upper surface of the fixing piece. A second lead screw is rotatably connected to the end of the first fixing plate away from the rotary disc.

A second servo motor is fixedly connected to the end of the fourth support plate away from the second lead screw. A pushing plate is rotatably connected to the outer surface of the second lead screw. A cutting knife is fixedly connected to the side of the pushing plate close to the fourth support plate. The cutting knife rotates. During the rotation process, the second servo motor drives the rotation of the second lead screw, further driving the pushing plate to move along the second lead screw. When the cutting knife moves towards the metal hose, the cutting knife contacts the metal hose, thereby cutting the hose and rotating simultaneously, but the metal hose does not rotate, thus controlling the all-round cutting of the metal hose by the cutting knife.

[0009] Preferably, the knocking mechanism includes a second fixing plate. An extending plate is fixedly connected to the outer surface of the second fixing plate. A rotating shaft is fixedly connected to the end of the extending plate away from the second fixing plate. A knocking piece is fixedly connected to the outer surface of the rotating shaft. A third telescopic spring is fixedly connected to the end of the knocking piece away from the rotating shaft. An impact ball is fixedly connected to the end of the third telescopic spring away from the knocking piece. The polishing outer shell rotates as the rotating disc rotates. During the rotation, it will indirectly collide with the impact ball, causing the polishing outer shell to vibrate. During the vibration, impurities such as metal rubber on the polishing rod and the brush will be shaken off.

[0010] Preferably, the polishing and cleaning mechanism includes a polishing outer shell. A polishing chamber is arranged on the inner surface of the polishing outer shell. A third fixing plate is fixedly connected to the upper surface of the polishing outer shell. A brush plate is fixedly connected to the outer surface of the third fixing plate. A brush is fixedly connected to the lower surface of the brush plate. A fifth support plate is fixedly connected to the inner surface of the polishing chamber. A polishing rod is rotatably connected to the outer surface of the fifth support plate. During the cutting process, the cutting tool may be damaged and worn due to extrusion contact with the metal. When the cutting tool moves forward, it will contact the polishing rod, causing the polishing rod to rotate, further polishing the cutting edge and surface of the cutting tool. The upper brush will also contact the outer surface of the cutting tool to clean the metal impurities attached to the cutting tool.

[0011] Preferably, the outer surface of the polishing outer shell is fixedly connected to the end of the support table away from the fixing piece. The lower surface of the second fixing plate is fixedly connected to the upper surface of the groove block. The outer surface of the rotating disc is rotatably connected to the inner surface of the groove block.

[0012] The beneficial effects of the present invention are as follows: (1) By setting the battery iron in the present invention and utilizing the adsorption effect of the electromagnet on the metal hose, when the electromagnet is energized, the adsorption force tightly fixes the lower end of the metal hose. The second telescopic spring below the electromagnet drags the sliding ring downward, and further the first telescopic spring pushes the fixed block to contact the lower surface of the sliding ring, thereby fixing the position of the metal hose. At the same time, it drags the upper end of the metal hose to straighten the metal hose. The upper limit plate above also limits the upward movement distance of the sliding ring, thus preventing the sliding ring from falling out of the device.

[0013] (2) By setting the first lead screw in the present invention, the servo motor drives the rotation of the first lead screw, so that the sliding piece drives the groove block to move along the direction of the lead screw, thereby driving the movement of the cutting mechanism, enabling the staff to control the cutting length and reducing the process of manual measurement.

[0014] (3) In the present invention, by setting the rotating disc to rotate on the inner surface of the groove block, the cutting tool is driven to rotate. During the rotation, the servo motor two drives the lead screw two to rotate, further driving the pushing plate to move along the lead screw two. When the cutting tool moves towards the metal hose, the cutting tool contacts the metal hose, thereby cutting the hose while rotating, but the metal hose does not rotate. Thus, the cutting tool is controlled to cut the metal hose in all directions, preventing the cut from being uneven and the internal metal wires of the hose from being pulled out during cutting.

[0015] (4) In the present invention, by setting the grinding rod to contact the cutting tool to grind the cutting tool, during the cutting process, the cutting tool may be damaged and worn due to contact and extrusion with the metal. When the cutting tool moves forward, it will contact the grinding rod, causing the grinding rod to rotate, further grinding the blade and surface of the cutting tool. The brush above will also contact the outer surface of the cutting tool to clean off the metal impurities attached to the cutting tool. At the same time, during the rotation of the cutting mechanism, the grinding housing will rotate with the rotation of the rotating disc. During the rotation, it will indirectly collide with the impact ball, causing the grinding housing to vibrate. During the vibration, the metal, rubber and other impurities on the grinding rod and the brush will be shaken off, thereby improving the efficiency of grinding and cleaning.

By using the adsorption effect of the electromagnet on the metal hose, when the electromagnet 723 is energized, the adsorption force firmly fixes the lower end of the metal hose. The second telescopic spring 725 below the electromagnet 723 pulls the sliding ring 721 to move downward. Further, the first telescopic spring 716 pushes the fixing block 717 to contact the lower surface of the sliding ring 721, thereby fixing the position of the metal hose. At the same time, the upper end of the metal hose is pulled to straighten the metal hose. The upper limiting plate 714 above also limits the upward movement distance of the sliding ring 721, thereby preventing the sliding ring 721 from falling out of the device.

The rotary disc 911 rotates on the inner surface of the groove block 806, thereby driving the cutting knife 919 to rotate. During the rotation, the second servo motor 917 drives the second lead screw 914 to rotate, further driving the pushing plate 918 to move along the second lead screw 914. When the cutting knife 919 moves towards the metal hose, the cutting knife 919 contacts the metal hose, thereby cutting the hose and rotating simultaneously, but the metal hose does not rotate, thus controlling the all-round cutting of the metal hose by the cutting knife 919, preventing the cut from being uneven and the internal metal wires of the hose from being pulled out during cutting.

[0025] The knocking mechanism 92 includes a second fixing plate 921. A protruding plate 922 is fixedly connected to the outer surface of the second fixing plate 921.

During the rotation of the cutting mechanism, the grinding housing 931 will rotate with the rotation of the rotating disc 911. During the rotation, it will indirectly collide with the impact ball 926, causing the grinding housing to vibrate. During the vibration, the impurities such as metal rubber on the grinding rod 937 and the brush 934 will be shaken off, thereby improving the grinding and cleaning efficiency.

[0026] The grinding and cleaning mechanism 93 includes a grinding housing 931. A grinding cavity 935 is arranged on the inner surface of the grinding housing 931.

A grinding rod 937 is rotatably connected to the outer surface of the fifth support plate 936. The grinding rod 937 contacts the cutting knife 919 to grind the cutting knife. During the cutting process, the cutting knife 919 may be damaged and worn due to contact with metal extrusion. When the cutting knife moves forward, it will contact the grinding rod 937, causing the grinding rod 937 to rotate, further grinding the blade edge and surface of the cutting knife 919. The upper brush 934 will also contact the outer surface of the cutting knife 919 to clean the metal impurities attached to the cutting knife.

[0027] The outer surface of the grinding housing 931 is fixedly connected to one end of the support platform 915 away from the fixing piece 912.

The outer surface of the rotating disc 911 is rotatably connected to the inner surface of the groove block 806.

[0028] The specific working process is as follows: During operation, first place the metal hose into the device. When the electromagnet 723 is powered on, the adsorption force firmly fixes the lower end of the metal hose. The telescopic spring two 725 below the electromagnet 723 pulls the sliding ring 721 downward, and further the telescopic spring one 716 pushes the fixed block 717 to contact the lower surface of the sliding ring 721, thereby fixing the position of the metal hose. At the same time, it pulls the upper end of the metal hose to straighten the metal hose. The upper limit plate 714 above also limits the upward movement distance of the sliding ring 721, thus preventing the sliding ring 721 from falling out of the device. After that, the servo motor one 804 drives the rotation of the lead screw one 801, so that the sliding piece 805 drives the groove block 806 to move along the direction of the lead screw one 801, thereby driving the movement of the cutting mechanism 9, enabling the staff to control the cutting length, reducing the manual measurement process. Subsequently, the rotating disc 911 rotates on the inner surface of the groove block 806, thereby driving the cutter 919 to rotate. During the rotation process, the servo motor two 917 drives the rotation of the lead screw two 914, further driving the pushing plate 918 to move along the lead screw two 914. During the process of the cutter 919 moving towards the metal hose, the cutter 919 contacts the metal hose, thereby cutting the hose. At the same time, the cutter rotates, but the metal hose does not rotate, thus controlling the all-round cutting of the metal hose by the cutter 919, preventing the cut from being uneven and the internal metal wires of the hose from being pulled out during cutting. Finally, during the cutting process, the cutter 919 may be damaged and worn due to contact with metal extrusion. When the cutter moves forward, it will contact the grinding rod 937, causing the grinding rod 937 to rotate, further grinding the blade and surface of the cutter 919. The brush 934 above will also contact the outer surface of the cutter 919 to clean the metal impurities attached to the cutter. At the same time, during the rotation of the cutting mechanism, the grinding housing 931 will rotate with the rotation of the rotating disc 911. During the rotation process, it will indirectly collide with the impact ball 926, causing the grinding housing to vibrate. During the vibration process, the metal, rubber and other impurities on the grinding rod 937 and the brush 934 will be shaken off, thereby improving the grinding and cleaning efficiency.
