[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the cleaning effect of the above solutions is unstable in actual use. Since the above devices cannot make the pressing structure and the blade move with each other, the pressing structure cannot generate friction on the blade surface. The blade surface is only cleaned by adhesion and squeezing, which has a poor cleaning effect on stubborn stains and reduces the cleaning effect of the above devices on the blade surface.

[0025] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0026] Example 1: This example provides a chopping knife for a forging hydraulic press, such as... Figure 1-3 As shown, it includes a base 1, a support plate 2 connected to the top of the base 1, a top plate 3 connected to the top of the support plate 2, a lifting component 4 connected to the top of the top plate 3 for controlling the device to lift and cut, a swing component 5 connected to the lifting component 4 for driving the cleaning structure to swing, a rotating component 6 connected to the swing component 5 for driving the cleaning structure to rotate.

[0027] The lifting component 4 includes an electric telescopic rod 401 connected to the top plate 3. The bottom of the electric telescopic rod 401 passes through the top plate 3 and is connected to a lifting plate 404. The top of the lifting plate 404 is connected to a sliding rod 402.

[0028] The top plate 3 is provided with a through hole corresponding to the sliding rod 402. A sleeve 403 is provided at the top of the through hole. The bottom of the sleeve 403 is connected to the top of the top plate 3. The sliding rod 402 is slidably connected to the inner wall of the sleeve 403. A sliding stop is provided at the top of the sliding rod 402. The diameter of the sliding stop is larger than the inner diameter of the sleeve 403. A cutting blade 405 is connected to the bottom of the lifting plate 404. The sleeve 403 and the sliding rod 402 are used to limit the lifting and sliding movement of the lifting plate 404.

[0029] The swing component 5 includes a transmission rod 502 connected to the side of the lifting plate 404. The support plate 2 has a vertical waist-shaped hole. The inner wall of the waist-shaped hole is slidably connected to the transmission rod 502. The transmission rod 502 is rotatably connected to two sets of rotating connecting parts 503. The other end of the rotating connecting part 503 is rotatably connected to a rotating shaft 504.

[0030] The support plate 2 is provided with two sets of symmetrical arc-shaped through grooves 501. The inner wall of the arc-shaped through grooves 501 is slidably connected to the rotating shaft 504. The end of the rotating shaft 504 away from the rotating connector 503 is connected to a friction roller 505 for cleaning the cutting blade 405.

[0031] The rotating component 6 includes a drive shaft 601 connected to the side of the friction roller 505 away from the rotating shaft 504. The drive shaft 601 is slidably connected to the inner wall of the arc-shaped through groove 501, and a drive gear 602 is connected to the outer arc surface of the drive shaft 601.

[0032] The specific working principle is as follows: This device can improve the cleaning effect on the side of the cutting blade 405. After each cut, the two sides of the blade surface can be cleaned in time, extending the service life of the cutting blade 405. When this device is in use, the electric telescopic rod 401 drives the lifting plate 404 to move vertically and linearly, thereby achieving the cutting effect of the cutting blade 405. During the vertical moving linear sliding process, the combination of the sliding rod 402 and the sleeve 403 can limit the vertical moving linear sliding of the lifting plate 404, ensuring that the cutting section of this device is vertical and accurate.

[0033] During the vertical lifting and linear sliding process of the lifting plate 404, the transmission rod 502 is driven to perform vertical lifting and linear sliding. At this time, under the transmission of the rotating connector 503, the rotating shaft 504 is driven to swing in an arc shape inside the arc-shaped through groove 501, thereby achieving the effect of synchronous mirror symmetrical swing of the symmetrical friction roller 505 on both sides of the cutting blade 405.

[0034] During the oscillation process of the friction roller 505, the transmission shaft 601 performs arc-shaped oscillation motion under the drive of the friction roller 505. At this time, the transmission gear 602 is driven to rotate through the combination of the transmission gear 602 and the arc-shaped rack 604, thereby realizing the effect of the transmission shaft 601 oscillating and rotating at the same time, thus realizing the effect of the friction roller 505 rotating, which increases the relative friction between the friction roller 505 and the side of the cutting blade 405.

[0035] Example 2: This example provides a chopping knife for a forging hydraulic press, such as... Figure 1-3 As shown, an arc-shaped component 603 is connected to the side of the support plate 2 away from the rotating connector 503. An arc-shaped rack 604 is connected to the outer arc surface of the arc-shaped component 603. The arc-shaped rack 604 meshes with the transmission gear 602 and is used to drive the transmission shaft 601 to rotate during the swinging process.

[0036] The friction rollers 505 are symmetrically arranged on both sides of the cutting blade 405. The outer arc surface of the friction rollers 505 is provided with cleaning textures, and the cleaning textures contact and press with both sides of the cutting blade 405.

[0037] The specific working principle is as follows: by making the arc of the arc-shaped part 603 the same as the arc of the arc-shaped through groove 501 and coinciding with the center of the circle, it can be ensured that the transmission gear 602 is always in contact with the arc-shaped rack 604 during the swinging motion, thereby ensuring the effect of driving the transmission shaft 601 to rotate during the swinging process of this device, and increasing the relative motion speed between the friction roller 505 and the side of the blade.

[0038] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
