Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] Such as figure 1 As shown, the present invention includes a conveyor belt 1 , an ultrasonic machine 4 , a quality inspection device 5 , a first cleaning mechanism 3 and a second cleaning mechanism 6 . The transmission belt 1 passes through the ultrasonic machine 4; the ultrasonic machine 4 is provided with an ultrasonic generator 41 and a passivation solution 42, and the part of the conveyor belt 1 located in the ultrasonic machine 4 is immersed in the passivation solution 42. The passivation solution 42 is made by mixing abrasive grains and water. The abrasive grains are SiC grains with a diameter of 1 μm-3 μm, and the mass concentration is 15-20%. Ultrasonic microscopic explosion is used to promote the cutting effect of the abrasive particles of the passivation solution 42 on the workpiece to act on the cutting edge of the cemented carbide blade 2 to passivate it,...

Abstract

The invention provides an ultrasonic passivating device and method for a carbide blade. The ultrasonic passivating device for the carbide blade comprises a conveying belt, an ultrasonic machine, a quality testing device, a first cleaning mechanism and a second cleaning mechanism. The conveying belt penetrates the ultrasonic machine. An ultrasonic generator and a passivating solution are arranged in the ultrasonic machine. The part, located in the ultrasonic machine, of the conveying belt is immersed in the passivating solution. An inflation gas pipe is arranged on the ultrasonic machine. The first cleaning mechanism and the second cleaning mechanism are located above the conveying belt and arranged at the two sides of the ultrasonic machine. The quality testing device is arranged at the tail end of the conveying belt. According to the ultrasonic passivating device and method, ultrasonic microcosmic explosions are utilized for promoting the cutting effect of adhesive particles of the passivating solution on a workpiece to act on a cutting edge of the carbide blade, so that the cutting edge is passivated, and passivating is even; and the material of the cutting edge of the carbide blade is hardened through the cavitation effect of ultrasonic waves while the cutting edge is passivated, and the service life of the carbide blade is prolonged.

Description

technical field [0001] The invention belongs to the technical field of processing and surface treatment of superhard materials, and in particular relates to an ultrasonic passivation device and a passivation method for a cemented carbide blade. Background technique [0002] In the modern machining industry, the application of cemented carbide is more and more extensive, and the application of cemented carbide is a key factor to promote the development of cutting technology. When the tool has the following two conditions, it is necessary to passivate the edge of the tool to improve the condition of the edge of the tool: 1) There are microscopic gaps (micro chipping and sawing) on ​​the edge of the tool after pressing, sintering, and grinding; 2) When the cutting edge of the knife must be sharp and have sufficient strength. The edge passivation quality of the tool is an important factor in determining the quality of the cemented carbide tool. Therefore, the edge passivati...
