Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a reverse-scratching cutter disc, a cutting tool and a processing device for a wind power casting product. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Reverse scoring tools are mainly used for milling operations in metal processing, especially when processing harder materials or when a good surface finish is required. Compared with traditional milling tools, reverse scoring tools can reduce burrs and tearing during the cutting process, thereby providing a better surface finish; since reverse scoring helps to better control cutting forces and usually produces lower cutting temperatures, it can reduce tool wear to a certain extent and extend tool life.

[0004] Traditional reverse scoring tools such as Figure 1-Figure 2 As shown, the triangular blade is installed. The four positions 01, 02, 03, and 04 are the inner slots for installing the triangular blade, which are mainly responsible for positioning the arc in the workpiece back-scratching area; the four positions 05, 06, 07, and 08 are the outer slots for installing the triangular blade, which are responsible for determining the relative length of the workpiece back-scratching area; 09 is the installation groove cross-section of the triangular back-scratching blade of the back-scratching tool. The blades are installed into the slots 01-08 in sequence to complete the back-scratching tool design. Due to the short edge line of the blade, the back-scratching area will be reduced accordingly. In order to increase the area of ​​the back-scratching area, the position of each slot needs to be changed accordingly, and the positioning is inaccurate; the blade contacts the workpiece vertically, and the cutting efficiency is low; the surface of the workpiece has a slope, and the cutting side of the blade needs to be ground. After changing the processing position, the blade cannot be used, which aggravates the waste of the blade. Summary of the invention

In this embodiment, the blade groove 3 is provided on a side end face of the branch 2 perpendicular to the circumferential direction of the cutter disc body 1, and the blade groove 3 matches the blade and is used to fix the blade. In this embodiment, along the radial direction of the cutter disc body 1, the inner end of at least one branch 2 is provided with a blade groove 3 for internal processing positioning of the counter-scratching area, and the outer end of at least one branch 2 is provided with a blade groove 3 for external processing positioning of the counter-scratching area, and the position between the inner end and the outer end of at least one branch 2 is provided with a blade groove 3.

[0029] In this embodiment, the cutter disc body 1 is provided with four branches 2 at equal intervals along the circumferential direction. Along the radial direction of the cutter disc body 1, a blade groove 3 is provided at the inner end of one of the branches 2, and blade grooves 3 are provided at the outer ends of two branches arranged at 90° to the branch. The last branch 2 is provided with a blade groove 3 at a set position between the inner end and the outer end.

[0030] In the present embodiment, the cutter disc groove 3 adopts a quadrilateral groove. Furthermore, the quadrilateral groove is a diamond groove, including a bottom groove surface 3-1, and the bottom groove surface 3-1 is a groove surface perpendicular to the circumferential direction of the cutter disc body 1. The three edges of the bottom groove surface 3-1 are connected with side groove surfaces, wherein, in the blade grooves located at the inner end and non-end positions of the branch 2, the two side groove surfaces radially distributed along the cutter disc body are respectively the first side groove surface 3-2 and the third side groove surface 3-3, wherein along the radial direction of the cutter disc body, the first side groove surface 3-2 is located on the inner side, close to the center of the cutter disc body 1, and the blade groove 3 located at the outer end of the branch is not provided with the third side groove surface 3-3, and the blade groove 3 directly extends to the outer end surface of the branch, and a second side groove surface 3-4 is provided between the bottom of the first side groove surface 3-2 and the third side groove surface 3-3.
