[0023] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0024] It should be noted that in the description of this utility model, the terms "lateral," "longitudinal," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] Reference Figure 1 and Figure 2 This utility model proposes a fixed-length flying shear device that can reduce the power of the fixed-length flying shear motor, including a servo motor 7, a transmission mechanism connected to the output shaft of the servo motor 7, a flying shear body 1 connected to the transmission mechanism, a fixed frame 2 supporting the flying shear body 1, and a first elastic buffer device 5 and a second elastic buffer device 6 located on both sides of the flying shear body 1.
[0026] Both the first elastic buffer device 5 and the second elastic buffer device 6 include a fixed plate fixed to the fixed frame 2, a buffer plate disposed opposite to the fixed plate, and an elastic element connecting the fixed plate and the buffer plate. When the servo motor 7 drives the flying shear body 1 to move between the first elastic buffer device 5 and the second elastic buffer device 6, the side of the flying shear body 1 can abut against the buffer plate of the first elastic buffer device 5 or the second elastic buffer device 6.
[0027] Furthermore, both sides of the flying shear body 1 are provided with buffer rods 11 for abutting against the buffer plate, and a buffer pad is installed at the head of the buffer rod 11. By setting the buffer rod 11 and the buffer pad to cooperate, the wear that may occur to the head of the buffer rod 11 due to impact is reduced.
[0028] In this embodiment, a groove is provided on the buffer plate, the shape of which is adapted to the end of the buffer rod 11. The free end of the buffer rod 11 is accommodated in the groove when the flying shear body 1 impacts the buffer plate. By providing a groove that matches the head of the buffer rod 11, the precise alignment of the buffer rod 11 is ensured.
[0029] Specifically, when the flying shear body 1 is stationary, the distance between the ends of the buffer rods 11 on both sides and the corresponding bottom wall of the groove is 5cm to 50cm.
[0030] In this embodiment, the elastic element is a spring. The flying shear body 1 is slidably connected to the fixed frame 2.
[0031] Furthermore, this embodiment proposes a specific structure for a sliding connection: a linear guide rail is fixed on the fixed frame 2, and a slider that can slide relative to the linear guide rail is installed on the linear guide rail. The bottom end of the flying shear body 1 is fixedly connected to the slider. The slider and the linear guide rail form a linear guide rail pair 4.
[0032] In this embodiment, the transmission mechanism includes a reducer 8 connected to the output shaft of the servo motor 7, a rack fixedly connected to the flying shear body 1, and a gear meshing with the rack. The fixed shaft of the gear is fixedly connected to the output shaft of the reducer 8. The rack and gear together form a rack and gear pair 3.
[0033] Furthermore, a brake 9 is installed on the low-speed shaft of the reducer 8. It is used in the initial position of the flying shear to overcome the elastic force of the initial position spring, so that the shear blade body 1 is in the initial position waiting for the next cut.
[0034] In this embodiment, the elastic element and the fixed plate are detachably connected. Therefore, when the elastic element malfunctions, it can be replaced. A snap-fit can be provided on the fixed plate, and the head of the elastic element is accommodated within the snap-fit to achieve a detachable connection.
[0035] The working process of this fixed-length flying shear device is as follows: The servo motor 7 drives the gear to rotate through the reducer 8 and coupling 10, thereby realizing the translation of the rack and pinion, which in turn drives the flying shear body 1 to translate. A brake 9 is installed on the low-speed shaft of the reducer 8, which is used in the initial position of the flying shear to overcome the elastic force of the second elastic buffer device 6, so that the shear body 1 is in the initial position waiting for the next cut. When the buffer rod 11 at the end of the flying shear body 1 hits the corresponding buffer plate, the spring effectively decelerates the flying shear body 1, and stores the kinetic energy of the flying shear body 1 as spring potential energy. Then, the spring potential energy is used to accelerate the flying shear body 1. The power of the servo motor 7 can be effectively reduced in both the acceleration and deceleration phases. Figure 3 As shown.
[0036] The fixed-length flying shear device proposed in this embodiment has the following beneficial effects:
[0037] 1. By setting a first elastic buffer device 5 and a second elastic buffer device 6 at both ends of the flying shear body 1, the first elastic buffer device 5 and the second elastic buffer device 6 effectively reduce the speed of the flying shear body 1, and at the same time store the kinetic energy of the flying shear body 1 as spring potential energy, and then use the spring potential energy to accelerate the flying shear body 1. The power of the servo motor 7 can be effectively reduced in both the acceleration and deceleration phases. On the one hand, it can achieve higher speed and smaller fixed length cutting, and on the other hand, it can reduce the power of the servo motor 7, thereby reducing the manufacturing cost of this fixed length flying shear device.
[0038] 2. This fixed-length flying shear device has the advantages of simple structure, stable and reliable operation, easy implementation and low cost.
[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model.
