Description
Technical Field
The invention belongs to the technical field of diamond roller manufacturing, and particularly relates to a high-precision sand feeding device and method for an electroplating diamond roller.
Background
The advent of various diamond rollers as a dressing tool necessary for form grinding has advanced the rapid development of the power grinding technology. The method has the advantages of short finishing time, long service life, high finishing precision, good consistency of processed parts and the like, and is widely applied to general industries such as automobiles, refrigeration, bearings, textile machinery, tools and the like and high-tech industries such as aerospace, ships, wind power, nuclear power, military industry and the like. With the continuous improvement of the complexity of the processed parts, more and more rollers with complex profiles, which are steep (the included angle between a tooth trace and a roller axis or a parallel line thereof is more than or equal to 72.5 degrees) and large fall (the tooth depth is 5mm-30 mm) are produced.
The common methods for manufacturing diamond rollers include electroplating and powder metallurgy, and the electroplating methods are divided into inner plating and outer plating. Patent publication No. CN112536737A provides a device and a method for rearrangement, uniform distribution and sanding of superhard material electroplating grinding wheel abrasive, which utilizes an outer plating method to deposit sanding on a grinding wheel matrix at one time. However, the plating method is difficult to achieve the consistency of the metal deposition rate at each part of the substrate, generally, the deposition rate at the convex part is high, and the deposition rate at the concave part is low, so the shape of the roller is changed after plating, and the precision is reduced.
The diamond roller manufactured by the inner plating method has the precision of 5 mu m, and is widely applied to the manufacturing of high-precision rollers. During inner plating, a sand cover with a proper size is placed in the center of the cavity, diamonds are filled into a gap between the inner wall of the cavity and the sand cover, and the diamonds are tamped to the greatest extent by using a sand tamping rod. For a common diamond roller, the tooth depth is shallow, the diamond is easy to cling to the surface of a cavity to enable the cavity to be completely sanded, and the precision of the roller can reach within 5 mu m. However, because the drop of the tooth form of the cavity with the complex profile is large and the tooth form is steep, it is difficult to ensure that the grinding material is fully filled into the tooth tip and other positions during sand tamping, the fit degree of the grinding material and the cavity wall is influenced slightly, the accuracy of the profile of the roller is poor, and the grinding material is lack at a certain position seriously, so that the roller lacks sand, which is an unacceptable defect in roller manufacturing.
