Description

Technical Field

[0001] The utility model relates to a special tool for cleaning aluminum stuck on a disc knife. Background Art

[0002] With the development of the metallurgical industry, disc shears are widely used in the shearing of sheet metal and aluminum strips. Shears are a very critical chess piece in the metallurgical industry. Common production line trimming shears are mainly composed of a base, two mobile frames, two turrets, a deburring roller and a knife disc adjustment mechanism. The turret is mounted on the mobile frame, and a shear blade bracket and a shear blade are mounted on it. When the disc shear is working, the equipment gap and overlap are set according to the rolling regulations. The dislocation shearing force of the upper and lower blades of the disc shear equipment acts on the edge of the strip, and the strip undergoes elastic deformation, plastic deformation, crack extension and material fracture. According to the viewpoint of modern metal physics, there are a large number of dislocations inside the metal. The essence of metal plastic deformation is the movement of dislocations. The yield limit of the material is the critical stress value required to start the dislocation to move. The lower blade is installed on the inside and mainly plays a supporting role, and the upper blade is installed on the outside and mainly plays a shearing role. At the beginning of shearing, the upper and lower surfaces of the strip undergo elastic deformation under the rolling action of the upper and lower shear blades of the disc shear. When the rolling force reaches the yield limit of the strip, plastic deformation occurs inside the metal, and at this time, there is a certain arc area at the edge of the upper shear blade. As the shearing continues, the upper shear blade continues to penetrate into the strip, and the strip will produce small cracks along the slip zone due to stress concentration at the edges of the upper and lower shear blades. Since there is a certain gap between the shear blades, a bending moment is formed on the strip between the shear blades under the action of the shear force. Under the action of this bending moment, the cracks at the blades will rapidly expand until the strip breaks, forming a fracture zone, and finally achieving precise shearing of the strip.

[0003] In the production process, in order to ensure that the strips provided to customers have good edge quality and fixed width, the strips need to be trimmed. The occurrence of quality defects not only damages the company's economic interests, but also has a negative impact on the corporate image. The edge quality problem after trimming directly affects the use of the client, and even causes damage to the customer's production equipment in serious cases. During the shearing process, due to the different alloy states of the aluminum strip, a layer of aluminum powder will accumulate on the disc knife, affecting the change of the disc knife side gap and resulting in unstable trimming quality. Summary of the invention

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0021] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0022] like Figure 1-3 As shown, a tool for cleaning aluminum stuck on a disc knife comprises a tool fixing handle 1, a blade 2 is installed on one end of the tool fixing handle, the tool fixing handle comprises a handle 3, a tool fixing disk 4 is installed on one end of the handle, the blade is installed on the side of the tool fixing disk away from the handle, when in use, the handle is held by hand, and the blade is driven by the handle to scrape the aluminum stuck on the cutting edge and the knife surface of the disc, and the aluminum stuck and the slight rust are scraped off to ensure that the cutting edge and the knife surface of the disc are smooth.

[0023] In this embodiment, for the sake of reasonable design, the body of the tool fixing disk is arc-shaped, that is, the body of the tool fixing disk has a small curvature, which is convenient for scraping off sticky aluminum and slight rust, and the blade can better fit the cleaning disc cutting edge and knife surface. A plurality of tool fixing fingers 5 for fixing the blade are spaced apart on the side of the tool fixing disk away from the handle, and there are gaps between the tool fixing fingers, which facilitate the removal of the blade when replacing the blade.

[0024] In this embodiment, in order to achieve the fixation of the blade, a horizontal branch fixing groove 6 is provided at the middle of the end of the tool fixing finger, and the branch fixing grooves of each tool fixing finger are on the same horizontal plane. The branch fixing grooves of each tool fixing finger constitute a tool fixing groove for fixing the tool, and the blade is fixed in the tool fixing groove. More specifically, the tool fixing finger is in the shape of a horizontally arranged strip, and the groove depth direction of the branch fixing groove is parallel to the plate length direction of the tool fixing finger, which facilitates the installation of the blade.

[0025] In this embodiment, in order to achieve a specific connection and fixation between the blade and the tool fixing groove, a through hole 8 connecting the branch fixing groove and penetrating the tool fixing finger is opened on the end of the tool fixing finger, and a through hole 9 is set on the blade corresponding to the through hole. A bolt 10 passing through the through hole is installed in the through hole, and the bolt head of the bolt abuts against one side plate of the tool fixing finger, and the threaded end of the bolt extends through the through hole. A nut 11 is screwed on the protruding end, and the nut abuts against the other side plate of the tool fixing finger. The blade is locked in the branch fixing groove by the cooperation of the bolt and the nut. Due to the presence of multiple branch fixing grooves, the overall connection is stable.

[0026] In this embodiment, in order to facilitate the blade to enter the branch fixing through slot, a chamfer 12 is provided on the notch edge of the branch fixing through slot.

[0027] In this embodiment, the outside of the tool fixing handle is coated with a wear-resistant layer. The tool fixing handle can be made of beech wood, because the texture and hardness of beech wood are relatively large. If an inappropriate blade is used, it is easy to cause breakage and cuts. Of course, it can also be made of other materials. At the same time, the wear-resistant layer can be an existing wear-resistant wood paint, or other coatings with similar functions.

[0028] In this embodiment, in order to facilitate hand holding and avoid injuries caused by friction between the operator's hand and the handle, the handle is covered with a foam layer 14.

[0029] In this embodiment, in order to prevent the installed blade from shaking, a cushion block 15 is sandwiched between the blades on one side of the groove wall of the branch fixing through groove, and a cushion block hole 16 is provided on the cushion block corresponding to the bolt.
