Description

Technical Field

[0001] The present invention relates to the technical field of metal wire cutting, and particularly to a wire rope cutting device. Background Art

[0002] A wire rope cutting device is a mechanical device specifically used for cutting wire ropes. Generally, it has the characteristics of high efficiency, precision and safety, and can work in various industrial environments.

[0003] The patent with the patent announcement number CN220092878U relates to a wire rope cutting device, belonging to the technical field of wire ropes. The patent includes an operation platform. Characteristically, mounting plates are fixedly installed on both sides of the operation platform. A limiting member is installed on one side of the mounting plate. The limiting member is used for limiting the wire rope. A cutting member is installed on the upper end of the operation platform. The cutting member is used for cutting the wire rope. The limiting member includes a bottom tube and a rotating cylinder. The bottom tube is fixedly installed on one side of the mounting plate. A sliding tube is slidably inserted into the inner wall of the bottom tube. This patent can clamp and limit multiple groups of wire ropes with different thicknesses, and can adjust the position of the cutting device according to the length of the wire rope that the user needs to cut, and is relatively flexible to use and has high practicability.

[0004] In the above patent, multiple groups of wire ropes with different thicknesses can be clamped and limited, and the position of the cutting device can be adjusted according to the length of the wire rope that the user needs to cut. It is relatively flexible to use and has high practicability. However, due to the relatively large hardness of the metal wire itself but with a certain elasticity, the metal wire may not be in a straightened state when cutting the metal wire, resulting in the cutting being affected and the cutting failing, thus affecting the efficiency. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a wire rope cutting device, which solves the problems put forward in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A wire rope cutting device includes a table board. A bottom board is fixedly installed at the bottom of the table board. A cutting wheel is arranged on the surface of the table board. An electric push rod is fixedly installed on the top of the bottom board. The output end of the electric push rod slidably penetrates through the inner and outer walls of the table board. A square base is fixedly installed at the top of the output end of the electric push rod. A feeding box is fixedly installed at the top of the output end of the electric push rod. A connecting cross bar is fixedly installed between the square base and the feeding box. A circular bracket is fixedly installed on the top of the square base. A rotating rod is rotatably installed on the surface of the circular bracket. A ring is rotatably installed on the side of the rotating rod away from the circular bracket. A wire reel is rotatably installed on the inner wall of the feeding box, and the wire reel is used to fix the metal wire entering the interior of the feeding box; A moving telescopic rod is slidably installed on the top of the square base. A driving device is arranged inside the moving telescopic rod. The output end of the moving telescopic rod is rotatably connected to a ring. The moving telescopic rod is used to drive the ring to rotate. The metal wire moves and contacts the cutting wheel and is cut off. Since the metal wire is squeezed by the arc-shaped clamping rod, the metal wire is limited during cutting.

[0007] According to the above technical solution, a receiving hopper is arranged on the surface of the table board. A concave block is slidably installed on the surface of the rotating rod. An arc-shaped clamping rod is rotatably installed on the inner wall of the concave block. An inclined panel is fixedly installed on the circumferential surface of the arc-shaped clamping rod. A moving rod slidably penetrates through the inner and outer walls of the concave block. The movement of the arc-shaped clamping rod drives the metal wire to move slightly, so that the metal wire is stretched while being limited. A buffer device for ensuring cutting accuracy and a protection device for improving safety during operation are arranged on the top of the bottom plate.

[0008] According to the above technical solution, a first torsion spring is arranged between the arc-shaped clamping rod and the concave block. The inclined panel contacts the moving rod. When the arc-shaped clamping rod no longer contacts the metal wire, the first torsion spring drives the arc-shaped clamping rod to reset.

[0009] According to the above technical solution, the buffer device includes: a hollow box, a sliding plate, a limiting plate, a reset telescopic rod, a sliding column and a brake lining. The hollow box is fixedly installed on the top of the bottom plate. The sliding plate is slidably installed on the inner wall of the hollow box. The limiting plate is fixedly installed on the top of the sliding plate. The reset telescopic rod is fixedly installed on the inner wall of the hollow box. The sliding column slidably penetrates through the inner and outer walls of the table board. The sliding column is fixedly installed at the bottom of the feeding box. The brake lining is slidably installed on the inner wall of the hollow box. The brake lining is fixedly connected to the free end of the reset telescopic rod. The reset of the reset telescopic rod drives the brake lining to move away from the sliding column, so that after the sliding column moves to the bottommost part, when the sliding column moves upward, it will not be restricted, so that when the metal wire moves downward and is cut, it can only move slowly downward.

[0010] According to the above technical solution, the buffer device further includes: an L-shaped rotating rod, a fixed block, a connecting rotating rod and a retaining rod. The L-shaped rotating rod is rotatably installed on the inner wall of the hollow box. The fixed block is fixedly installed on the circumferential surface of the sliding column. The connecting rotating rod is rotatably installed at the end of the fixed block away from the sliding column. The retaining rod is fixedly installed at the bottom of the fixed block. The movement of the connecting rotating rod drives the L-shaped rotating rod to rotate upward. The rotation of the L-shaped rotating rod will contact the brake lining and drive the brake lining to move towards the sliding column.

[0011] According to the above technical solution, the limit plate is in contact with the brake pad, and a No. 2 torsion spring is arranged between the connecting rotating rod and the fixed block. The No. 2 torsion spring drives the connecting rotating rod to reset when the connecting rotating rod is no longer in contact with the L-shaped rotating rod.

[0012] According to the above technical scheme, the protective device includes: two buttons, a connecting block, a sloped block, two locking plates, an arc block, a long plate, a reset plate and a triangular block. The two buttons are arranged on the top of the table top, the connecting block is fixedly installed on the bottom of the button, a storage groove is opened inside the table top, the sloped block is fixedly installed on the surface of the connecting block, the two locking plates are slidably installed on the bottom of the inner wall of the storage groove, the arc block is fixedly installed on the top of the locking plate, a locking groove is opened on the surface of the output end of the electric push rod, and the locking plate no longer contacts the locking groove after moving, so that the output end of the electric push rod is no longer limited, the long plate is fixedly installed between the two locking plates, the reset plate is fixedly installed on the surface of the long plate, and the triangular block is fixedly installed on the circumferential surface of the sliding column.

[0013] According to the above technical solution, a reset spring is arranged between the positioning plate and the table top, and the arc block is in contact with the inclined block. The reset spring drives the positioning plate to reset when the arc block is no longer in contact with the inclined block.

[0014] The present invention provides a metal wire rope cutting device, which has the following beneficial effects: (1) The invention moves the metal wire to contact the cutting wheel and be cut. Since the metal wire is squeezed by the arc clamp rod, it is limited during cutting, which prevents the friction between the metal wire and the cutting wheel from being too large, causing the metal wire to be caught by the blades of the cutting wheel and unable to be cut. The cutting efficiency of the device is improved. The concave block moves to drive the arc clamp rod to move away from the circular bracket. The movement of the arc clamp rod drives the metal wire to move slightly, so that the metal wire is stretched while being limited, which prevents the metal wire from being in an unstraightened state during cutting, causing the cutting to be affected and resulting in cutting failure. The continuity of the cutting is ensured, and the production of defective products is reduced.

[0015] (2) The invention, after the sliding column moves to the bottom, is not restricted when the sliding column moves to the top, so that the metal wire can only move slowly to the bottom when it moves to the bottom and cuts, preventing the metal wire from moving too fast when it is not completely cut off, causing the cut surface to be too rough, thus affecting normal use, and improving the cutting accuracy of the device. By connecting the rotating rod to drive the L-shaped rotating rod to rotate toward the top, the L-shaped rotating rod will contact the brake pad and drive the brake pad to move in the direction of the sliding column, so that the device can be automatically reset and can be used multiple times, thereby improving the practicality of the device.

[0016] (3) In this invention, the movement of the arc-shaped block drives the clamping plate to move towards the button. After the clamping plate moves, it no longer contacts the card slot, so that the output end of the electric push rod is no longer limited. When the device is cutting, the operator needs to press the button with both hands at the same time to operate the device for cutting, ensuring the safety of the operator during operation. The movement of the reset plate drives the long plate to move away from the button, preventing the device from aging due to long-term use or being unable to reset when the device is damaged, ensuring the normal operation of the device and preventing the work efficiency from being affected.

Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0020] See also Figures 1 - 5 , one embodiment of the present invention is: a wire rope cutting device, comprising a table board 1, a bottom plate 2 is fixedly installed at the bottom of the table board 1, a cutting wheel 3 is arranged on the surface of the table board 1, an electric push rod 51 is fixedly installed on the top of the bottom plate 2, the output end of the electric push rod 51 slides through the inner and outer walls of the table board 1, a square base 52 is fixedly installed on the top of the output end of the electric push rod 51, a feed box 55 is fixedly installed on the top of the output end of the electric push rod 51, a connecting cross bar 54 is fixedly installed between the square base 52 and the feed box 55, a circular bracket 57 is fixedly installed on the top of the square base 52, a rotating rod 59 is rotatably installed on the surface of the circular bracket 57, and a ring 58 is rotatably installed on the side of the rotating rod 59 away from the circular bracket 57; A winding wheel 56, which is rotatably mounted on the inner wall of the feed box 55, and is used to fix the metal wire entering the feed box 55; The mobile telescopic rod 53 is slidably installed on the top of the square base 52. A driving device is arranged inside the mobile telescopic rod 53. The output end of the mobile telescopic rod 53 is rotatably connected with the circular ring 58. The mobile telescopic rod 53 is used to drive the circular ring 58 to rotate, so as to prevent the friction between the metal wire and the cutting wheel 3 from being too large, causing the metal wire to be caught in the blades of the cutting wheel 3 during cutting and making it impossible to cut, thereby improving the cutting efficiency of the device during cutting.

[0021] A material receiving hopper 4 is provided on the surface of the table top 1, a concave block 510 is slidably installed on the surface of the rotating rod 59, an arc clamping rod 511 is rotatably installed on the inner wall of the concave block 510, an inclined panel 512 is fixedly installed on the circumferential surface of the arc clamping rod 511, and a moving rod 513 is slidably penetrated through the inner and outer walls of the concave block 510 to prevent the metal wire from being in an unstraightened state during cutting, which affects the cutting and causes the cutting failure, thereby ensuring the continuity of the cutting and reducing the production of defective products.

[0022] A torsion spring No. 1 is arranged between the arc clamping rod 511 and the concave block 510, and the inclined plate 512 is in contact with the moving rod 513. The arc clamping rod 511 is driven to reset by the torsion spring No. 1 when the arc clamping rod 511 is no longer in contact with the metal wire.

[0023] When this embodiment is working: the metal wire is put into the feed box 55, the movement of the metal wire drives the winding wheel 56 to rotate, and the metal wire is affected by the gap between the winding wheels 56, so that the metal wire can only move in a straight line along the specified route, and then the driving device drives the movable telescopic rod 53 to move, and the movement of the movable telescopic rod 53 drives the circular ring 58 to rotate, and the rotation of the circular ring 58 drives the rotating rod 59 to rotate, and the rotation of the rotating rod 59 drives the concave block 510 to rotate, and the rotation of the concave block 510 drives the arc clamping rod 511 to rotate, and the rotation of the arc clamping rod 511 will contact the metal wire and apply pressure to the metal wire, and then the output end of the electric push rod 51 moves toward the bottom, driving the square base 52 and the feed box 55 to move toward the bottom, and the square base 52 and the feed box 55 move toward the bottom, driving the metal wire to move toward the bottom, and the metal wire moves to contact the cutting wheel 3 and is cut off. Because the metal wire is squeezed by the arc clamping rod 511, the metal wire is limited during cutting to prevent the metal wire from contacting the cutting wheel 3 The friction between them is too large, which causes the metal wire to be entangled in the blades of the cutting wheel 3 during cutting, making it impossible to cut, thereby improving the cutting efficiency of the device during cutting. After the arc clamping rod 511 contacts the metal wire, the arc clamping rod 511 rotates to drive the inclined plate 512 to rotate. The inclined plate 512 rotates and contacts with the moving rod 513. The inclined plate 512 rotates and drives the moving rod 513 to move in the direction of the circular bracket 57 and contact the circular bracket 57. After the moving rod 513 contacts the circular bracket 57, the moving rod 513 continues to move, causing the concave block 510 to move away from the circular bracket 57. The movement of the concave block 510 drives the arc clamping rod 511 to move away from the circular bracket 57. The movement of the arc clamping rod 511 drives the metal wire to move slightly, so that the metal wire is stretched while being limited, thereby preventing the metal wire from being in an unstraightened state when being cut, resulting in the cutting being affected and causing the cutting to fail, thereby ensuring the continuity of the cutting and reducing the production of defective products.

[0024] See also Figures 1 - 8 On the basis of the above embodiment, in another embodiment of the present invention, a buffer device for ensuring cutting accuracy and a protective device for improving safety during operation are provided on the top of the base plate 2, wherein the buffer device comprises: a hollow box 61, a sliding plate 62, a limiting plate 63, a resetting telescopic rod 64, a sliding column 65 and a brake pad 66, the hollow box 61 is fixedly mounted on the top of the base plate 2, the sliding plate 62 is slidably mounted on the inner wall of the hollow box 61, the limiting plate 63 is fixedly mounted on the top of the sliding plate 62, the resetting telescopic rod 64 is fixedly mounted on the inner wall of the hollow box 61, the sliding column 65 slides through the inner and outer walls of the table board 1, the sliding column 65 is fixedly mounted on the bottom of the feed box 55, the brake pad 66 is slidably mounted on the inner wall of the hollow box 61, and the brake pad 66 is fixedly connected to the free end of the resetting telescopic rod 64 to prevent the metal wire from moving when the cutting is not completely disconnected due to excessive cutting speed, resulting in the cutting surface being too rough, affecting normal use, thereby improving the cutting accuracy of the device.

[0025] The buffer device further includes: an L-shaped rotating rod 67, a fixed block 68, a connecting rotating rod 69 and a shifting rod 610. The L-shaped rotating rod 67 is rotatably installed on the inner wall of the hollow box 61. The fixed block 68 is fixedly installed on the circumferential surface of the sliding column 65. The connecting rotating rod 69 is rotatably installed at one end of the fixed block 68 away from the sliding column 65. The shifting rod 610 is fixedly installed at the bottom of the fixed block 68, enabling the device to automatically reset and be reusable multiple times, improving the practicality of the device.

[0026] The limiting plate 63 contacts the brake lining 66. A second torsion spring is arranged between the connecting rotating rod 69 and the fixed block 68. When the connecting rotating rod 69 no longer contacts the L-shaped rotating rod 67, the second torsion spring drives the connecting rotating rod 69 to reset.

[0027] The protection device includes: two buttons 71, a connecting block 72, an inclined plane block 73, two clamping plates 74, a cambered surface block 75, a long plate 76, a reset plate 77 and a triangular block 78. The two buttons 71 are both arranged on the top of the table board 1. The connecting block 72 is fixedly installed at the bottom of the button 71. A storage groove is formed inside the table board 1. The inclined plane block 73 is fixedly installed on the surface of the connecting block 72. The two clamping plates 74 are slidably installed at the bottom of the inner wall of the storage groove. The cambered surface block 75 is fixedly installed on the top of the clamping plate 74. A card slot is formed on the surface of the output end of the electric push rod 51. When the device is cutting, the operator needs to press the two buttons 71 simultaneously with both hands to operate the device to cut, ensuring the safety of the operator during operation. The long plate 76 is fixedly installed between the two clamping plates 74. The reset plate 77 is fixedly installed on the surface of the long plate 76. The triangular block 78 is fixedly installed on the circumferential surface of the sliding column 65, preventing the device from aging after long-term use or being unable to reset when the device is damaged, ensuring the normal operation of the device and preventing the work efficiency from being affected.

[0028] A reset spring is arranged between the clamping plate 74 and the table board 1. The cambered surface block 75 contacts the inclined plane block 73. When the cambered surface block 75 no longer contacts the inclined plane block 73, the reset spring drives the clamping plate 74 to reset.

[0029] During the operation of this embodiment: The movement of the feeding box 55 drives the sliding column 65 to move downward. When the sliding column 65 moves, it will contact and rub against the brake pad 66, restricting the speed of the sliding column 65 when it moves downward. After the sliding column 65 moves to the bottom, it will contact the sliding plate 62. The movement of the sliding column 65 drives the sliding plate 62 to move downward, and the movement of the sliding plate 62 drives the limiting plate 63 to move downward. After the limiting plate 63 moves, it no longer contacts the brake pad 66. Subsequently, the reset telescopic rod 64 resets and drives the brake pad 66 to move away from the sliding column 65, so that when the sliding column 65 moves to the bottom and then moves upward, it will not be restricted. When the metal wire moves downward for cutting, it can only move slowly downward, preventing the cutting speed from being too fast, which may cause the metal wire to move before it is completely cut off, resulting in a too rough cutting surface and affecting normal use, and improving the cutting accuracy of the device. The upward movement of the sliding column 65 drives the fixed block 68 to move upward, and the upward movement of the fixed block 68 drives the connecting rotating rod 69 to move upward. The movement of the connecting rotating rod 69 will contact the L-shaped rotating rod 67. Since the connecting rotating rod 69 is blocked by the stop rod 610, the connecting rotating rod 69 cannot rotate downward. The movement of the connecting rotating rod 69 drives the L-shaped rotating rod 67 to rotate upward, and the rotation of the L-shaped rotating rod 67 will contact the brake pad 66 and drive the brake pad 66 to move toward the sliding column 65, enabling the device to automatically reset and be used multiple times, improving the practicality of the device.

[0030] At the same time, press two buttons 71 downward. The downward movement of the buttons 71 drives the connecting block 72 to move downward, and the movement of the connecting block 72 drives the inclined plane block 73 to move downward. When the inclined plane block 73 moves, it will contact the arc-shaped block 75, and the movement of the inclined plane block 73 drives the arc-shaped block 75 to move toward the button 71. The movement of the arc-shaped block 75 drives the clamping plate 74 to move toward the button 71. After the clamping plate 74 moves, it no longer contacts the card slot, so that the output end of the electric push rod 51 is no longer limited. When the device is cutting, the operator needs to press the buttons 71 with both hands at the same time to operate the device for cutting, ensuring the safety of the operator during operation. The downward movement of the sliding column 65 drives the triangular block 78 to move downward. When the triangular block 78 moves, it will contact the reset plate 77 and drive the reset plate 77 to move away from the button 71. The movement of the reset plate 77 drives the long plate 76 to move away from the button 71, preventing the device from aging or being damaged after long-term use and being unable to reset, ensuring the normal operation of the device and preventing the work efficiency from being affected.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
