Embodiment 1

[0045] to combine figure 1 , figure 2 with image 3 , a kind of cutting edge cutter with arc-shaped cutting edge in this embodiment includes a cutting blade body, such as figure 1 As shown in , the upper surface of the cutting blade body is an arc surface, which can be processed into an arc surface, and the cutting edge surface 13 of the cutting blade body is a spiral arc surface, that is, the cutting edge surface 13 is a smooth transition of the arc surface, because the cutting edge surface 13 The two sides are not in the same section, forming a certain spiral angle, forming a spiral arc surface. Such as figure 2 , image 3 As shown in , the bottom surface 14 of the scissors is connected with the side 11 of the scissors with a scissors protrusion 17, which is easy to snap into the installation groove during installation, so as to limit the displacement of the scissors body and make the fixation more reliable; The junction of projection 17 and the bottom surface of the cu...

Embodiment 2

[0048] A kind of cutting edge cutting tool processing method of arc-shaped cutting edge of the present embodiment, refer to Figure 4 , its processing technology is:

[0049] 1) For blanking, plane milling, leaving a margin of 2.5-3mm; milling the side, leaving a margin of 2.5-2.8mm; during milling, correct the angle between the upper and lower planes and the side to 90°.

[0050] 2) Roughly grind the plane and side of the blank, the plane allowance is 2.0-2.5mm, the side allowance is 1.5-2.0mm, and the verticality is corrected; the end face is milled and ground, and the angle between the end face, the plane and the side is corrected to 90° °, leaving a margin of 1mm.

[0051] 3) Mark the bolt hole 15 and the thread hole 16 of the shearing blade to be processed, and reserve the amount of grinding, reserve 1mm margin from the side, and reserve 0.25mm margin from the end face, and determine the drilling center point after marking; Reason, to wire hole 16 marking positioning, t...

Abstract

The invention discloses a machining method of a smashing cutter with an arc-shaped cutting edge, and belongs to the field of cutter machining. The upper surface of a shear blade body is an arc surface, a cutting edge surface of the shear blade body is a spiral arc surface, and the bottom surface and the side face of the shear blade body are connected with shear blade bumps. During machining, milling is performed, a plane is grinded, and then drilling is performed to machine bolt holes and screw holes. A blank is subjected to heat treatment, tempering is performed for three times after quenching, and fitness reaches 56-58HRC. The shear blade bumps are machined by linear cutting after fine grinding, the arc surface of the shear blade body is machined after grinding, and finally, a cutting edge surface is machined at a machining center. The structure and the machining process of the smashing cutter are improved, internal toughness of the shear blade body is enhanced, so that the shear blade body can bear larger shear force and cannot be easily peeled off, and the service life of the shear blade body is prolonged.

Description

technical field [0001] The invention relates to the technical field of cutting tools, and more specifically, relates to a cutting edge cutting tool processing method with an arc-shaped cutting edge. Background technique [0002] The chipping cutter, also known as the chipping shear, is the core equipment of the medium and heavy plate rolling production line, and can replace the roll-cut double-sided shear in the medium and heavy plate production line. For medium and heavy plate production lines of small and medium iron and steel enterprises, the use of chipping shears can bring considerable economic benefits to the enterprise. The chipping shears are located behind the disc shears in the medium and heavy plate production line, and are used to cut the waste edges cut by the disc shears, which is beneficial to the collection and recycling of waste edges. [0003] The scraper scissors blade is the core part of the scraper shears, usually used in pairs, it can complete the shea...
