Description

Technical Field

[0001] The utility model belongs to the technical field of processing the cutting edge of a shearing blade, and more specifically relates to a rotary drum tooling for processing the cutting edge of a shearing blade. Background Art

[0002] The disc edge shear is a functional shear blade that is mostly used in hot-rolled medium and thick plate production lines to cut off the scrap material generated by the disc shear longitudinal cutting of the plate strip for easy collection. The disc edge shear is a consumable on the edge shear equipment, with a general life of 7-12 days and a large demand on the production line. During production and processing, the rest of the edge shear is easy to process, but the edge needs to be processed separately due to the special shape of its curved surface and the high quality requirements of the disc edge shear.

[0003] Existing processing methods often use wire cutting for processing. The edge arc surface accuracy of the broken edge shear blade produced by wire cutting is poor, and this method can only process the broken edge shear blade piece by piece, resulting in low production efficiency.

[0004] After searching, the application case with Chinese patent publication number CN 107336045 A discloses a tool for turning the transverse curvature of a scrap edge shear. The application case includes a mounting plate and a fixing seat, a fixing seat is provided on one side of the mounting plate, the fixing seat is provided with a screw hole, the mounting plate and the fixing seat are fixedly connected by studs, a mounting block is provided on the top of the fixing seat, the fixing seat and the mounting block are fixedly connected by fixing screws, two groups of protrusions are provided at the bottom of the mounting block, and a groove matching the protrusions is provided at the junction of the fixing seat and the mounting block. The application case fixes the fixing seat to the mounting plate by studs, fixes the mounting block to the fixing seat by fixing screws, mounts the workpiece to be processed on one side of the mounting block by using the fixing holes provided on the side of the mounting block, and mounts the mounting plate on the lathe by using the circular through hole, so as to realize the processing of the transverse curvature of the workpiece. Although the application case can effectively improve the processing efficiency. However, the turning tool of the application case needs to clamp the broken edge shear blade from the side, which makes the operation relatively inconvenient; at the same time, the turning tool of the application case needs to improve the clamping stability of the broken edge shear blade.

[0036] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0037] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0038] The utility model is further described below in conjunction with specific embodiments.

[0039] Example 1

[0040] like Figure 1 , Figure 2 As shown, a rotary drum tool for processing the edge of a shearing blade in this embodiment includes a fixed plate 1, and a plurality of mounting grooves 11 are provided in the circumference of the fixed plate 1.

[0041] The mounting groove 11 is a stepped groove, which includes a stepped low groove and a stepped high groove. The stepped low groove is used to accommodate the edge shearing blade 2 to be processed; the stepped high groove is equipped with a pressing block 3, which is aligned and pressed from one side of the edge shearing blade 2.

[0042] Compared with the traditional wire cutting technology, the rotary drum tooling of this embodiment can be directly fixed on the CNC lathe to turn the cutting edge, which effectively solves the problems of low traditional processing efficiency and poor arc surface processing quality.

[0043] Specifically, refer to Figure 3 , Figure 4 As shown, the pressing block 3 is a wedge-shaped block, and the pressing block 3 and the step high groove are provided with corresponding fastening holes 31, and the two are connected by fasteners.

[0044] In addition, in order to ensure the accuracy of the installation position of the scrap edge shearing blade 2 in the installation groove 11, a positioning pin 21 is provided on the scrap edge shearing blade 2, and a positioning hole 12 corresponding to the positioning pin 21 is provided in the step low groove. Through the mutual cooperation of the positioning pin 21 and the positioning hole 12, the accuracy of the position of the scrap edge shearing blade 2 in the installation groove 11 can be ensured.

[0045] Specifically in this embodiment, there are 10 installation grooves 11 , which are distributed on the outer circumference of the fixing plate 1 in an inclined manner and at equal intervals.

[0046] The fastener is a fastening bolt, and the fastening hole 31 provided on the step high groove is a threaded hole matched with the bolt.

[0047] The fixing plate 1 is made of alloy structural steel, such as 42CrMo, which has excellent mechanical properties and high strength, good hardenability and machinability, and has high yield strength, tensile strength and hardness. Due to its high chromium and molybdenum content, it also has good wear resistance, high temperature resistance and corrosion resistance.

[0048] The rotary drum tooling for processing the edge of the scrap edge shearing blade of this embodiment first places the scrap edge shearing blade 2 in the corresponding installation groove 11, and ensures that the positioning pin 21 is inserted into the corresponding positioning hole 12, so as to complete the precision positioning of the scrap edge shearing blade 2;

[0049] Next, the wedge block is fixed in the installation slot 11 by means of bolts, and the wedge block is squeezed by adjusting the bolts, thereby applying a lateral squeezing force to the edge scraping shear blade 2 to fix the shear blade.

[0050] Then, the rotary drum fixture with the shear blade clamped is fixed on the CNC lathe to turn the cutting edge, so that 10 disc shear blades can be processed at one time. After turning, the processed shear blade can be removed by loosening the bolts, and a new batch of shear blades to be processed can be re-clamped. The rotary drum fixture can realize the rapid clamping and disassembly of the workpiece, greatly improving the processing efficiency.

[0051] Example 2

[0052] Since the drum tooling processes a large number of cutting edges at one time and the turning speed is high, a large amount of heat is generated during the processing. If this heat cannot be removed in time, it will cause burns and cracks on the workpiece surface, which is not conducive to ensuring the quality of the edge arc processing. Therefore, it is necessary to improve the heat dissipation effect of the drum tooling to further ensure the processing effect and surface quality.

[0053] like Figure 1 , Figure 2 As shown, a through hole is opened at the center of the fixing plate 1, and a plurality of heat dissipation holes 13 are arranged on the peripheral wall of the through hole. The heat dissipation holes 13 penetrate the peripheral wall of the fixing plate 1 and are connected with the step low groove.

[0054] like Figure 5 As shown, a heat dissipation mechanism 4 is also provided in the through hole, and the heat dissipation mechanism 4 includes a connecting plate 41, a rotating shaft 42 and a fan blade 43. The connecting plate 41 is provided on the end surface of the fixed disk 1. One end of the rotating shaft 42 is provided on the connecting plate 41, and the other end extends into the central through hole of the fixed disk 1. A plurality of fan blades 43 are provided along the axial direction of the rotating shaft 42.

[0055] Specifically in this embodiment, a slot 14 is provided on the end surface of the fixing plate 1, and the end of the connecting plate 41 is clamped in the slot 14, and the two are fastened by bolts. At the same time, each step low groove is equipped with two heat dissipation holes 13 (distributed along the axial direction), and are respectively located on both sides of the positioning hole 12.

[0056] The rotary drum tooling of the present embodiment is used for processing the cutting edge of the shearing blade. Through the arrangement of the heat dissipation holes 13 and the heat dissipation mechanism 4, the rotary force of the machine tool shaft is utilized to realize rotation during the processing, so as to generate wind force and cool the workpiece through the heat dissipation holes 13 of the tooling, thereby preventing thermal deformation and ensuring the processing quality of the arc surface of the cutting edge.

[0057] In addition, the iron filings cut off during the drum tooling processing are easy to splash, thereby posing certain safety hazards. For this reason, in the present embodiment, a protective cover 5 is also provided at the end of the fixed disk 1.

[0058] Specifically, refer to Figure 1 , Figure 6 As shown, the protective cover 5 is provided with a protrusion 51 with a hole, and the protective cover 5 is arranged on the end surface of the fixing plate 1 by bolts and is located on the outer side of the connecting plate 41. Through the arrangement of the protrusion 51, a certain gap is left between the protective cover 5 and the end surface of the fixing plate 1, which is also conducive to the heat dissipation of the workpiece.

[0059] In addition, the length of the outer edge of the protective cover 5 needs to be greater than the length of the scrap shear blade 2 extending out of the fixed plate 1 to ensure that the flying iron chips can be stopped.

[0060] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
