Superhard material electroplating grinding wheel abrasive rearrangement uniform distribution sanding device and method

Abstract

The invention provides a device and method for rearranging and evenly distributing sand on super-hard material electroplated grinding wheel abrasives, which includes support plates and cover plates correspondingly arranged up and down, upper sand shafts are arranged between the support plates, and the upper sand shafts are fixed A grinding wheel base is provided, a sand cover is provided between the supporting plate and the cover plate, superhard abrasives are arranged between the sand covers, and the grinding wheel base is placed in the superhard abrasives. The invention can improve the consistency of the abrasive density, realize the quantitative addition of abrasives by specifying the amount of abrasives, ensure the consistency of the pressure in the jig each time the sand is applied, and realize the rotation and downward movement of the grinding wheel through the characteristics of thread matching, so that it will be close to the surface of the grinding wheel base The abrasives are rearranged to ensure the uniformity of abrasive distribution, and the consistency of the abrasive density of each grinding wheel is controlled under the premise that the total power remains unchanged. At the same time, the method can realize the success of one-time sanding, realize the single-time sanding requirement of the electroplated grinding wheel profile, eliminate the impact of sand filling on the plated size of the grinding wheel, and can effectively reduce the runout of the plated profile of the grinding wheel.

Description

technical field [0001] The invention relates to the technical field of superhard material electroplated abrasive tool manufacturing, in particular to a superhard material electroplated grinding wheel abrasive rearrangement uniform distribution sanding device and method. Background technique [0002] In the manufacturing process of electroplated abrasives, the electroplated abrasives with coarse grain abrasives (grain size above 0.1mm) usually adopt the "buried sand method", that is, use less than 0.3-0.6A / dm 2 The current density of the grinding wheel is directly buried in the abrasive, and it is kept for a certain period of time for sand electroplating, and then the excess abrasive is washed away for thickening electroplating. For grinding wheels whose dimensional accuracy is required to be less than 0.005mm and the particle size of electroplated abrasives to be more than 0.1mm, the existing sand embedding method has the following problems: the amount of embedding sand is u...

Problems solved by technology

For grinding wheels whose dimensional accuracy is required to be less than 0.005mm and the particle size of electroplated abrasives to be more than 0.1mm, the existing sand embedding method has the following problems: the amount of embedding sand is uncontrollable, and the density of abrasives electroplated in different batches of the same electricity has large fluctuations; It is difficult to fill evenly during the addition process, and the accumulation density of abrasives at each position is different, which leads to the problem of abrasive agglomeration in the abrasive layer of the grinding wheel; it is difficult to successfully apply sand at one time, and it is necessary to fill the sand-deficient position several times, resulting in large fluctuations in the beating of the grinding wheel profile after plating ; It is difficult to effectively control the consistency and stability of the abrasive layer thickness of the grinding wheel

The above problems have restricted the technical progress of electroplated grinding wheels with high precision and complex profiles, and become a difficult problem in the industry
