Embodiment 1

[0023] S1. Disc shear edge treatment: Clean the disc shear edge with cleaning solution. After cleaning, use a dryer for wind intervention treatment. After air drying, polish, polish and sandblast the disc shear edge. , after the treatment is completed, use the cleaning solution again to clean the cutting edge of the disc;

[0024] S2. Inner coating coating: the inner coating adopts carbide coating, adopts Ti target, places the disc shears treated in step S1 in a vacuum furnace, evacuates to less than 5Pa, and heats the disc shears at the same time , so that the surface temperature of the disc shears is controlled at 300°C. At this time, argon and nitrogen can be introduced into the vacuum furnace, the bias voltage and ion source are turned on, and ion plating is performed to obtain an inner coating. The thickness of the inner coating is 0.2 μm. The bias voltage is 300V, the flow rate of argon gas is 20 sccm, the flow rate of nitrogen gas is 10 sccm, and the carbide coating is ...

Abstract

The invention discloses a cutting edge PVD coating method for a disc shear for high-strength steel plate shearing, and relates to the technical field of disc shear cutting edge machining. The method includes the steps of S1, disc shear cutting edge treatment, wherein a disc shear cutting edge is washed through washing liquid, the disc shear cutting edge is subjected to air-drying pretreatment through a dryer after being washed, the disc shear cutting edge is ground, polished and sand-blasted after being air-dried, and the disc shear cutting edge is washed through the washing liquid again afterbeing treated. According to the cutting edge PVD coating method for the disc shear for high-strength steel plate shearing, the disc shear cutting edge is coated with three coatings through a PVC process, on the premise of guaranteeing the ultrathin coatings, the hardness of the disc shear cutting edge is greatly improved, the disc shear cutting edge has good abrasion resistance, and meanwhile hasgood high-temperature resistance, the disc shear cutting edge has a low friction coefficient during shearing and good self-lubricating performance, and meanwhile the machining process is simple and easy to carry out, free of contamination and zero in emission in the machining process and convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of disc shear edge processing, in particular to a PVD coating method for disc shear edge cutting for high-strength steel plates. Background technique [0002] Disc shears are only used for edge trimming of strip steel in the transverse cutting unit, and can be used for longitudinal continuous shearing of narrow and wide strip steel in the longitudinal shearing unit. It can be used as raw material for cold-rolled strip The main equipment of the cold-rolled strip slitting and recoiling production line. [0003] At present, when the disc scissors are in use, in order to ensure the sharpness and wear resistance of the cutting edge of the disc scissors, it is necessary to use cemented carbide and powder metallurgy high-speed steel to make the disc scissors, but during the grinding process of the disc scissors due to The effect of grinding force will cause defects such as microscopic zigzag edge formed by microsc...
