Problems solved by technology

In the prior art, its wear-resistant layer adopts hard alloy brazing layer or wear-resistant material surfacing layer, but both methods have its disadvantages. Although the hard alloy brazing layer has good wear resistance, its adhesion is small, Poor impact resistance; wear-resistant material surfacing layer adhesion or impact resistance is good but wear resistance is poor

Embodiment 1

[0013] Example 1: The wear-resistant layer is the electroplating processing method of the φ80 spectacle plate with the diamond composite coating inlaid with the nickel layer carcass:

[0014] 1. Soak the φ80 spectacle plate in sodium hydroxide aqueous solution, rinse with water, soak in 5% dilute sulfuric acid for 10 minutes, then soak in 30% concentrated hydrochloric acid for 5 minutes, take it out and perform ultrasonic cleaning.

[0015] 2. Plating a nickel bottom layer on the surface of the substrate: put the cleaned φ80 spectacle plate into the electrolytic cell as the cathode, and the anode uses pure nickel balls. The composition and ratio of the electroplating solution are: nickel sulfate 200 g / L, nickel chloride 40-60 g / L, boric acid 40-60 g / L, temperature 40-50°C, pH value kept at about 4, current density 10 ampere / square decimeter.

[0016] 3. Densely cover the coated diamond particles with a size of 35 meshes on the entire surface of the nickel bottom layer, perform...

Embodiment 2

[0020] Embodiment 2: the wear-resisting layer is the electroless plating processing method of the φ 80 spectacle plate of the cubic boron nitride composite coating of nickel layer carcass wrapping, except that following two points are different, the method step of embodiment 2 is all with embodiment 1 is the same.

[0021] First, the inlaid particles use cubic boron nitride instead of diamond or coated diamond; second, the nickel-plated bottom layer or nickel inlaid layer is electroless plating, or chemical immersion plating, and electroless nickel plating does not require external Electric current, the method of depositing a layer of nickel on the surface of metal parts by redox action. The composition and proportioning of electroless nickel plating solution in this example are: nickel sulfate 25-30 gram / liter, sodium hypophosphite 27-32 gram / liter, additive 65-75 gram / liter, and reaction temperature is 80-90 degree.

[0022] The main salt in the electroless nickel plating s...

Abstract

The invention discloses a cutting ring and a glasses plate, which comprise a cutting ring and a glasses plate matrix provided with an abrasion-resistant layer, wherein the abrasion-resistant layer is a diamond or cubic boron nitride composite plating layer wrapped by a nickel layer carcass. The processing method comprises the following steps of: cleaning a material by adopting layer-by-layer piling and ultrasonic wave, plating the material in one layer at every time with the thickness of only one diamond granule or cubic boron nitride granule, and piling the material layer by layer to form a composite plating layer so as to form the abrasion-resistant layer of the cutting ring and the glasses plate matrix. The abrasion-resistant layer not only has extremely excellent abrasion resistance, but also has the characteristics of good adhesiveness and strong impact resistance. Compared with the hard alloy abrasion-resistant layer, the service life of the plating layer with the same thickness under the same working condition is about 20 times longer; and the surface of the formed plating layer is uniform and flat so as to meet the requirement of workpiece cooperation or leak tightness of the cutting ring and the glasses plate.

Description

technical field [0001] The invention relates to a cutting ring and a spectacle plate of a concrete conveying pump. Background technique [0002] Among the components of concrete pump equipment, the cutting ring and the spectacle plate are a pair of relatively moving parts. The assembly gap between the two is between 0.1 and 0.2 mm. The surface of the cutting ring and the spectacle plate are welded with a layer of wear-resistant material. The cutting ring Cutting the concrete with high pressure with the spectacle plate, the working environment is harsh, and there are high requirements for the wear resistance and impact resistance of the wear-resistant layer; and as the main components, the service life of the cutting ring and the spectacle plate is determined Improve the working efficiency and service life of the concrete pump. In the prior art, the wear-resistant layer adopts a hard alloy brazing layer or a wear-resistant material surfacing layer, but both methods have thei...
