[0031] The following is the specific embodiment of the present application and in conjunction with the accompanying drawings, the technical scheme of the present application is further described, but the present application is not limited to these embodiments. In the following description, specific details such as specific configuration and assembly are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.
[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.
[0033] The present application provides a movable blade holder for a shearing machine, and a scrap steel shearing machine equipped with the movable blade holder. The scrap steel shearing machine is provided with a fixed fixed blade and a movable movable blade holder, and the movable blade holder cooperates with the fixed blade to shear the material through up and down reciprocating motion. The movable blade holder provided in the present application uses blades of the same shape and size specifications, which improves the convenience of after-sales spare parts. The following is a detailed description with reference to the accompanying drawings.
[0034] like Figure 1 and Figure 2 As shown, the movable blade holder 100 for shearing machine comprises: a movable blade seat 10, on which a plurality of blades 20 are mounted, and the plurality of blades 20 have the same shape and size. The plurality of blades 20 are arranged alternately vertically and horizontally, and the projection formed by projecting downward along the moving direction of the movable blade seat 10 into the horizontal plane is bent.
[0035] Figure 2 The projection formed by projecting the multiple blades 20 of the movable tool holder 100 downward into the horizontal plane along the moving direction of the movable tool holder 10 is shown. Along the extension direction K of the projection from the first end to the second end, at the corner position, the end of the previous blade is located outside the end face of the next blade and covers the end face of the next blade, so that the multiple blades are alternately arranged head to tail to make the projection bend. It should be understood that the projection formed by the multiple blades 20 can extend in two directions, and the extension direction K refers to only one direction.
[0036] Figure 3 Shows three consecutive blades on the moving tool holder, Figure 4 The corresponding figure shows three consecutive blades on the projection of the moving tool holder. Figure 3 and Figure 4 The three blades are marked as A1, A2, and A3, respectively, and the A2 blade is located between the A1 blade and the A3 blade. Figure 4 In the projection structure shown, the thickness of the blade is h, the length of the blade is s, the A1 blade, the A2 blade, and the A3 blade correspond to the three cutting edges a1, a2, and a3 on the movable tool holder respectively, and the lengths of the cutting edges a1, a2, and a3 are p1, p2, and p3 respectively.
[0037] For the A1 blade and the cutting edge a1 corresponding to the A1 blade, the length of the cutting edge a1 is p1. Since the cutting edge a1 is composed of the cutting edge in the length direction of the A1 blade alone, the length p1 of the cutting edge a1 is exactly the blade length s, p1=s.
[0038] For the A2 blade and the corresponding cutting edge a2 of the A2 blade, the length of the cutting edge a2 is p2. On the side close to the A3 blade, the end of the A2 blade is located outside the end face of the A3 blade and covers the end face of the A3 blade. On the side close to the A1 blade, the end of the A1 blade is located outside the end face of the A2 blade and covers the end face of the A2 blade. According to the geometric relationship, the cutting edge a2 is composed of a cutting edge in the length direction of the A2 blade and a cutting edge in the thickness direction of the A3 blade. The lengths of the two are s-h and h respectively. Therefore, the length calculation formula of the cutting edge a2 is as follows: p2=s-h+h=s, which is exactly the blade length s.
[0039] For the A3 blade and the cutting edge a3 corresponding to the A3 blade, the length of the cutting edge a3 is p3. Since the cutting edge a3 is composed of the cutting edge in the length direction of the A3 blade alone, the length p3 of the cutting edge a3 is exactly the blade length s, p3=s.
[0040] It can be seen that when the A1 blade, the A2 blade, and the A3 blade have the same size specifications, the lengths of the corresponding three sections of the cutting edge a1, a2, and a3 are all s. Therefore, under the blade arrangement form of the present application, the movable tool holder uses a single specification blade, and the lengths of the cutting edges on it are kept roughly the same. Therefore, the blades at different positions on the movable tool holder can be used interchangeably, and the blades can be universal, and only one after-sales spare part needs to be prepared, thereby improving the convenience of after-sales spare parts and reducing the customer's maintenance costs.
[0041] like Figure 2 As shown, in projection, an inner corner 21 that is concave relative to the movable blade seat 10 or an outer corner 22 that is convex relative to the movable blade seat 10 is formed between adjacent blades. At the position of the inner corner 21 of the part, for the B1 blade and the B2 blade that constitute the inner corner 21 and the end of the B1 blade is located outside the end face of the B2 blade and covers the end face of the B2 blade, the movable blade seat 10 is provided with an avoidance groove 11 on one side of the B2 blade along the end edge of the B1 blade to avoid the end of the B1 blade. Further, at the position of the inner corner 21 where the avoidance groove 11 is provided, the end of the B1 blade is higher than the end of the B2 blade. Further, at the position of the inner corner 21 where the avoidance groove 11 is provided, the B1 blade is deflected upward in the direction pointing to the inner corner 21.
[0042] In projection, the B1 blade and the B2 blade form an inner corner 21 at the transition position, and the outer side of the end face of the B2 blade covers the end face of the B2 blade. Figure 5 The movable blade holder 10 is provided with an escape groove 11 along the end edge of the B1 blade on one side of the B2 blade. The escape groove 11 is provided to facilitate the installation and removal of the B1 blade. In a specific structural example, as Figure 5 As shown, the end of the B1 blade is higher than the end of the B2 blade, and an avoidance groove 11 is arranged at the edge of the end of the B1 blade. Figure 5 As shown, the B1 blade is deflected upward in the direction pointing to the inner corner 21. Figure 1 As shown, in a specific structural example, the avoidance groove 11 is provided only at the position of one inner corner 21 .
[0043] like Figure 1 As shown, in one embodiment of the present application, at the position of the partial inner corner 21, for the B1 blade and the B2 blade constituting the inner corner 21, the end of the B1 blade is located outside the end face of the B2 blade and covers the end face of the B2 blade, the end of the B1 blade is lower than the end of the B2 blade and the end of the B1 blade is lower than the bottom of the movable blade holder 10 on the B2 blade side. At this type of inner corner position, there is no need to set an avoidance groove on the movable blade holder to avoid the blade end.
[0044] In one embodiment of the present application, at the position of the partial inner corner 21, for the B1 blade and the B2 blade constituting the inner corner 21, the end of the B1 blade is located outside the end face of the B2 blade and covers the end face of the B2 blade, and the end of the B1 blade is highly overlapped with the end of the B2 blade. At this type of inner corner position, there is no need to set an avoidance groove on the movable blade seat to avoid the blade end.
[0045] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, on a movable blade holder 100 for a shearing machine, a plurality of blades 20 are alternately arranged vertically and horizontally, and the projection formed by projecting downward along the moving direction of the movable blade holder 10 into a horizontal plane is in a step shape.
[0046] In one embodiment of the present application, a plurality of blades are alternately arranged vertically and horizontally, and the projection formed by projecting downward along the moving direction of the movable blade holder onto the horizontal plane is concave and convex.
[0047] The present application also provides a scrap steel shearing machine, referring to Figure 6 and Figure 7 The scrap steel shearing machine includes a gantry 300, a fixed fixed knife 30, and a movable knife holder 100 for the shearing machine provided in the previous part. The movable knife holder can make up and down reciprocating movements to make the movable knife holder 100 for the shearing machine combine or separate with the fixed knife 30 to shear the material. The scrap steel shearing machine is a multi-knife shear, and the fixed knife and the movable knife of the movable knife holder are both composed of multiple blades, and the fixed knife and the movable knife are both bent, forming a bent shearing line during shearing. In one embodiment of the present application, on the movable knife holder for the shearing machine, a plurality of blades are alternately arranged vertically and horizontally, and the projection formed by projecting downward along the moving direction of the movable knife holder into the horizontal plane is in a stepped shape. In another embodiment of the present application, a plurality of blades are alternately arranged vertically and horizontally, and the projection formed by projecting downward along the moving direction of the movable knife holder into the horizontal plane is in a concave and convex shape. The movable knife holder 100 uses blades with the same shape and size specifications.
[0048] In the technical solution of the present application, the movable knife holder for the shearing machine uses blades of the same shape and size specifications. The blades in different positions can be used interchangeably. The blades can be universal, and only one after-sales spare part needs to be prepared, thereby improving the convenience of after-sales spare parts and reducing customers' maintenance costs.
