Embodiment 1

[0092] A method for processing the edge surface of a broken edge shearing edge, the steps are as follows:

[0093] 1. Turning: install the cutting edge to be processed on the turning and grinding fixture and then assemble it into the lathe, and the lathe will perform rough turning on the surface 103 of the cutting edge cutting edge to be processed;

[0094] 2. Milling: Install the broken edge cutting edge after rough turning in step 1 on the milling fixture and then assemble it into the milling machine, and the milling machine will perform milling processing on the broken edge cutting edge surface 103;

[0095] 3. Grinding: Install the broken edge shearing blade after milling in step 2 on the turning-grinding fixture and then assemble it into the grinding machine, and the grinding machine performs fine grinding processing on the broken edge shearing edge surface 103 .

[0096] like Figure 20 As shown in the figure, the cutting edge cutting edge processing method of the prese...

Embodiment 2

[0099] like figure 1 and Image 6 As shown, a method for processing the edge surface of a broken edge shearing edge in the present embodiment is further improved on the basis of Embodiment 1, and the turning and grinding fixture includes:

[0100] The base body 11, which is a columnar body;

[0101] an assembling table 110, which is arranged at the center of one end face of the base body 11, and is used for assembling the fixture on the machine tool;

[0102] The mounting surface 12 is a plane disposed on the side surface of the base body 11, and the mounting surface 12 is horizontal with the central axis of the base body 11;

[0103] a mounting hole 120, which is formed on the mounting surface 12, and whose shape matches the mounting hole 102 of the cutting edge shear;

[0104] The concave structure 13 is formed on one side of the mounting surface 12 along the central axis of the base body 11 , and is used for placing the lower eaves 101 of the broken edge cutting edge.

Abstract

The invention discloses a scrap cutter edge surface machining method, and belongs to the field of scrap cutter edge machining. The scrap cutter edge surface machining method comprises the following steps: (1) turning: scrap cutter edges to be machined are assembled in a lathe after installation on a turning and grinding fixture; and scrap cutter edge surfaces to be machined are roughly turned by the lathe; (2) milling: the scrap cutter edges roughly turned in the step (1) are assembled in a milling machine after installation on a milling fixture; and the scrap cutter edge surfaces are milled by the milling machine; and (3) grinding: the scrap cutter edges milled in the step (2) are assembled into a grinding machine after installation on the turning and grinding fixture; and the scrap cutter edge surfaces are finely grinded by the grinding machine. The edge surfaces of the scrap cutter edges to be machined are machined through the turning, milling and grinding steps, and all the steps can be performed at the same time, so that the machining method achieves higher overall efficiency; and through each step machining, the precision of the scrap cutter edge surfaces is continuously improved, and the scrap cutting effect and the service life of the scrap cutter edges are improved.

Description

technical field [0001] The invention belongs to the field of cutting edge cutting edge processing, and more particularly relates to a cutting edge cutting edge processing method. Background technique [0002] Shredding shears are commonly used equipment in material processing. They are used to cut the edges of materials to ensure the quality of the edges. There are shearing blades on the shearing shears. The shearing blades can cut the materials. The structure of the cutting edge of the cutting edge shears used is as follows, including: the cutting edge cutting base body 100, its bottom surface is a plane, the top surface is a curved surface; the top surface of the cutting edge cutting base body 100 is downwardly provided with a cutting edge cutting installation hole 102, which is Through holes; one side of the base body 100 of the broken edge shears is formed with a lower eave 101, and the other side is the broken edge cutting edge surface 103, and the broken edge cutting e...
