DETAILED DESCRIPTION

[0023] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0024] Please refer to Figure 1 and Figure 2 , the embodiment of the present disclosure provides a segmented cutting device for hard abrasive wire, which comprises a base 1, a pushing mechanism, a vertical plate 3, a fixed knife 4, a knife disc 5 and a rotating rod 6. Among them, the telescopic rod 2 is installed on the base 1. The vertical plate 3 is fixed at one end of the base 1, and is provided with a through hole for the hard abrasive wire to pass through. The fixed knife 4 is installed on the cavity wall of the through hole. The knife disc 5 is arranged outside the fixed knife 4. The middle part of the rotating rod 6 is rotationally connected with the vertical plate 3 through a shaft, one end of the rotating rod 6 close to the through hole is connected with the outer ring of the thrust bearing 7, the inner ring of the thrust bearing 7 is coaxially connected with the knife disc 5, and the other end is rotationally connected with the output end of the pushing mechanism.

[0025] It can be understood that the hard steel wire is passed through the fixed knife 4 at the cavity wall of the through hole, the pushing mechanism is started, the pushing mechanism is elongated upward to push one end of the rotating rod 6 to move upward, so that the other end of the rotating rod 6 can drive the knife disc 5 to move downward to close to the hard steel wire, and the knife disc 5 cooperates with the fixed knife 4 to cut the hard steel wire. Further, the knife disc 5 is rotationally connected with the rotating rod 6 through the thrust bearing 7, the hard steel wire will give the knife disc 5 a tangential force in the cutting process, so that the knife disc 5 can rotate, the rotating knife disc 5 can give the hard steel wire fracture a certain friction force, so that the fracture is more smooth. At the same time, the hardness of the hard steel wire is positively related to the rotation angle of the knife disc 5, the rotation of the knife disc 5 makes the cutting part of the blade change constantly, the wear of the blade is more uniform, and the maintenance and replacement frequency is greatly reduced.

[0026] In one embodiment, the cutting device further includes a limiting component 8, which includes a fixed plate 81, a screw 82, a nut, and a baffle 83. The fixed plate 81 is rotatably connected to the upright plate 3. Further, the upright plate 3, which is connected to the rotating rod 6, extends axially outward to pass through the rotating rod 6 and is fixedly connected to the fixed plate 81. The screw 82 is threadedly connected to the fixed plate 81. The nut is sleeved on the outer periphery of the screw 82. The baffle 83 is fixed at the end of the screw 82 near the opening, meaning that the baffle 83 will not rotate synchronously with the rotating rod during rotation. When it is necessary to adjust the segment length of the hard steel wire, rotate the nut away from the fixed plate 81, then rotate the screw 82 to drive the baffle 83 forward or backward to a preset position, and finally rotate the nut closer to the fixed plate 81 to restrict the rotation of the screw 82 relative to the upright plate 3. The distance from the preset position of the baffle 83 to the upright plate 3 is the segment length of the hard steel wire.

[0027] In one embodiment, there are two nuts, which are respectively located on both sides of the fixing plate 81 to prevent the screw 82 from rotating relative to the upright plate 3 during the limiting process of the baffle 83.

[0028] In one embodiment, the actuating mechanism includes a foot switch 91, a motor 92, a hydraulic rod 2, a hydraulic pump, and a solenoid directional valve 93. The foot switch 91 is used to control the rotation of the motor 92. The rotating shaft of the motor 92 rotates with the pump wheel of the hydraulic pump. The hydraulic pump is used to provide power to the hydraulic rod. The output end of the hydraulic rod 2 is rotatably connected to one end of the rotating rod 6. The solenoid directional valve 93 is used to control the flow direction of the hydraulic oil.

[0029] In one embodiment, the cutting device further includes a first proximity switch 95 and a second proximity switch 96 respectively fixed to the vertical plate 3. The first proximity switch 95 and the second proximity switch 96 are electrically connected to the solenoid directional valve 93 and are used to control the rotation angle of the rotating rod 6. The solenoid directional valve 93 of the hydraulic mechanism is controlled by the change in distance from the two proximity switches to cause the piston of the hydraulic rod to reciprocate within a certain range.

[0030] In one embodiment, the cutting device includes a feed trough 10, which is installed on the base 1 near the vertical plate 3. The trough shape of the feed trough 10 is adapted to the outer periphery of the hard abrasive wire.

[0031] The operator places the bristles in the feed trough 10, adjusts the baffle 83 to the position of the upright plate 3 according to the required bristle length, and presses the foot switch 91. The motor 92 drives the hydraulic pump to pressurize and raise the hydraulic rod. The rotating rod 6 is pushed by the hydraulic rod and rotates around the fulcrum, causing the cutter head 5 to move downward to complete the cutting of the bristles. When one end of the rotating rod 6 reaches the position of the second proximity switch 96, the second proximity switch 96 closes, causing the solenoid reversing valve 93 to change the pressure direction, causing the hydraulic rod piston to move downward and drive one end of the rotating rod 6 back to the initial position (the position of the first proximity switch 95). The hydraulic mechanism stops running, and the equipment completes one cutting cycle.
