Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In actual use, because the existing device adjusts the cutting length of the blank through a screw and a screw barrel, the operator cannot accurately adjust the number of rotations of the screw, which leads to deviations in the cutting length of the nut blank and affects the quality of nut production.

[0019] In view of this, the present invention provides a hexagonal nut blank cutting device, which solves the problem that in actual use, the existing device adjusts the cutting length of the blank by means of a screw and a screw barrel. The operator cannot accurately adjust the number of rotations of the screw, which leads to deviations in the cutting length of the nut blank and affects the quality of nut production.

[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0021] Example 1: By Figure 1-4 It is known that a hexagonal nut blank cutting device includes a worktable 1, a placement platform 2 fixedly connected to the top of the worktable 1, a placement groove 7 opened on the top of the placement platform 2, a cutter 3 installed on one side above the placement groove 7, a servo motor 9 fixedly connected to the outer wall of the cutter 3, and the hexagonal nut blank cutting device also includes a pushing device 4, a moving component 5, and a collecting component 6. The pushing device 4 is installed on the top of the placement platform 2; the moving component 5 is installed on the outer wall of the cutter 3; and the collecting component 6 is installed on one side of the top of the worktable 1. The pushing device 4 drives the blank to move in the placement groove 7, the moving component 5 drives the cutter 3 to cut the blank, and the collecting component 6 collects the cut blank. In the specific implementation process, it is worth noting that the placement table 2 is fixedly connected to the top center of the workbench 1 by welding or bolting. A through-hole placement groove 7 is provided on its top, with a cross-sectional shape of the groove 7 matching the shape of the hexagonal nut blank in a regular hexagonal shape. The groove depth is slightly greater than the blank thickness, and the groove width is fitted with the blank width to ensure smooth movement of the blank while preventing deviation during movement. The placement table 2 is made of wear-resistant cast iron to extend its service life. The cutter 3 is made of high-speed steel in a disc shape with sharpened edges. Its central shaft is fixedly connected to the output end of the servo motor 9 via a coupling. The servo motor 9 is a high-precision servo motor with forward and reverse rotation functions, mounted on the moving component 5 via a motor bracket. When the motor is working, it drives the cutter 3 to rotate at high speed, realizing the cutting action of the blank. The model of the servo motor 9 is not limited, as long as it meets the actual use requirements. The pushing device 4 is used to cut the blank along the placement groove 7. Position pushing, the moving component 5 is installed on one side of the placement table 2, which is used to drive the cutter 3 to move in a direction perpendicular to the movement of the blank, that is, in the vertical or horizontal direction, to realize the cutting feed action. The collecting component 6 is installed on the top of the worktable 1 near the discharge end of the placement table 2, which is used to receive and collect the cut nut blanks. The cut blanks will slide out of the placement groove 7 and fall into the collecting component 6 under the push of the subsequent uncut blanks. The placement groove 7 is open on the side near the collecting component 6, which makes it easier for the blanks to slide down. Furthermore, the pushing device 4 includes a push rod 41, a bracket 42, an electric slider 43, and an electric slide bar 44. The push rod 41 is movably connected to the inner wall of the placement groove 7; the bracket 42 is fixedly connected to the top of the push rod 41 and its bottom is fixedly connected to the top of the placement platform 2; the electric slider 43 is fixedly connected to the bottom of the bracket 42; the electric slide bar 44 is movably connected to the inner wall of the electric slider 43 and is fixedly connected to the top of the placement platform 2; wherein, through the cooperation of the electric slide bar 44 and the electric slider 43, the bracket 42 and the push rod 41 push the billet to move. In the specific implementation process, it is worth noting that the push rod 41 is made of wear-resistant metal and is long and narrow. Its cross-sectional shape is adapted to the inner wall of the placement groove 7, such as a regular hexagon or rectangle, matching the shape of the billet. This ensures that the push rod 41 can slide smoothly along the inner wall of the placement groove 7 without shaking. The length of the push rod 41 is slightly longer than the distance from the feed end of the placement groove 7 to the cutting position. The end face of the push rod 41 closest to the billet is polished to ensure a tight fit with the end of the billet and prevent the billet from shifting during pushing. The end of the push rod 41 furthest from the billet is fixedly connected to the bracket 42. The movement of the bracket 42 drives the push rod to move synchronously. The electric slider 43 is a standard component that matches the electric slider 44. Its inner wall has a groove that matches the electric slider 44. Wear-resistant sliders or balls are installed in the groove to reduce friction during movement. The top of the electric slider 43 is fixedly connected to the bottom of the bracket 42 by bolts, and the bottom is movably fitted onto the outer wall of the electric slider 44. Driven by the electric slide bar 44, the device can reciprocate linearly along its length. The electric slider 43 has a built-in drive motor and transmission gears. It can start, stop and speed adjustment by receiving control signals. When the device is started, the control system sends a signal to the electric slider 43 according to the preset blank cutting length. Under the guidance of the electric slide bar 44, the electric slider 43 moves along the length of the electric slide bar 44. The push rod 41 moves synchronously through the bracket 42. The end of the push rod 41 that extends into the placement groove 7 pushes the blank along the inner wall of the placement groove 7 until the blank reaches the preset cutting position. At this time, the electric slider 43 receives a stop signal and maintains its position. After the cutter 3 finishes cutting, the electric slider 43 starts again and pushes the next section of blank to the cutting position to realize continuous pushing operation. Through the cooperation of the electric slide bar 44 and the electric slider 43, the pushing device 4 can realize the precise positioning and pushing of the blank, ensure the consistency of the cutting length, and improve the cutting accuracy and work efficiency. Furthermore, two fixing rings 8 are provided on both sides below the cutter 3. Both fixing rings 8 are located above the placement groove 7 and are fixedly connected to the top of the placement platform 2.

[0022] In the specific implementation process, it is worth noting that the inner wall of the fixing ring 8 is provided with a gasket, and the surface of the gasket is smooth. In this way, when the fixing ring 8 fixes the blank, it will not affect the movement of the blank in the placement groove 7, ensuring the stability of the blank during cutting.

[0023] Example 2: From Figure 1-4 It is known that the moving component 5 includes a mounting frame 51, an electric push rod 52, a mounting plate 53, and a limiting component 54. The mounting frame 51 is fixedly connected to the top of the placement platform 2; the electric push rod 52 is fixedly connected to the top of the inner wall of the mounting frame 51; the mounting plate 53 is fixedly connected to the bottom of the electric push rod 52, with its inner wall movably connected to the outer wall of the cutter 3, and its outer wall fixedly connected to the outer wall of the servo motor 9; the limiting component 54 is installed on the outer wall of the mounting plate 53; wherein, through the cooperation of the electric push rod 52 and the mounting frame 51, the mounting plate 53 drives the cutter 3 to rise and fall, and the limiting component 54 stabilizes the mounting plate 53 during movement; In the specific implementation process, it is worth noting that the mounting frame 51 adopts a frame structure welded from square steel or angle steel, and is generally in an inverted "U" shape spanning the top of the placement platform 2. The bottom is fixedly connected to the top of the placement platform 2 by bolts, and the connection part is reinforced with ribs to improve the overall stability. The top of the inner wall of the crossbeam of the mounting frame 51 has reserved mounting holes for the electric push rod 52, ensuring that the axis of the electric push rod 52 is perpendicular to the surface of the placement platform 2 after installation, providing a vertical guide foundation for the lifting of the cutter 3. The height of the mounting frame 51 must meet the maximum lifting stroke requirement of the cutter 3, and the distance between the crossbeam and the placement platform 2 must avoid the placement groove 7 and the fixing ring. 8. To avoid structural interference, the rated thrust and stroke of the electric push rod 52 are designed according to the weight of the cutter 3 and the required cutting depth, ensuring that it can stably drive the cutter 3 to complete the lifting action and has precise position control capability. The cutting depth can be set through the control system to meet the cutting requirements of blanks of different thicknesses. The two electric push rods 52 are connected together by a synchronizer to make the two electric push rods 52 stable when driving the mounting plate 53 to move. When the mounting plate 53 moves, the limiting component 54 can ensure that it moves stably and will not deviate. The model of the electric push rod 52 is not limited, as long as it meets the actual use. Furthermore, the limiting component 54 includes a slide groove 541 and a slide rod 542. The slide groove 541 is formed on the inner wall of the mounting bracket 51; the slide rod 542 is fixedly connected to the outer wall of the mounting plate 53 and slidably engaged with the inner wall of the slide groove 541; wherein, through the cooperation of the slide groove 541 and the slide rod 542, the mounting plate 53 is stabilized when it is raised and lowered. In the specific implementation process, it is worth noting that the size of the slide rod 542 is smaller than the inner wall of the slide groove 541. This ensures that the slide rod 542 moves stably within the slide groove 541 when it is raised or lowered, so that the mounting plate 53 is stable when it is raised or lowered. Furthermore, the collection component 6 includes a groove 61, a collection box 62, a limiting block 63, and a pin 64. The groove 61 is formed on the top side of the workbench 1; the collection box 62 is inserted into the inner wall of the groove 61; the limiting block 63 is disposed above the collection box 62 and is fixedly connected to the outer wall of the workbench 1; the pin 64 is inserted into the inner wall of the limiting block 63, and one end of the pin 64 is inserted into the inner wall of the collection box 62; wherein, through the cooperation of the limiting block 63 and the pin 64, the collection box 62 is fixed to the inner wall of the groove 61. In the specific implementation process, it is worth noting that the groove 61 is opened on the top of the workbench 1 near the discharge end of the placement table 2. It has a rectangular groove structure. The length and width of the groove 61 are slightly larger than the bottom size of the collection box 62. The depth is designed to be 5-10cm, which can not only ensure the stable placement of the collection box 62, but also facilitate the quick picking and placing of the operator. Through holes are opened on the surface of the limiting block 63 and the collection box 62, which can satisfy the insertion of the pin 64 into the limiting block 63 and the collection box 62 to fix the collection box 62 in the groove 61.
