Description

A kind of upper sand device of electroplating extra hard material grinding wheel of manufacturing

Technical field

The utility model relates to a kind of upper sand device, relates in particular to a kind of upper sand device of electroplating extra hard material grinding wheel of manufacturing.

Background technology

Electroplate extra hard material grinding wheel and have the total serviceability of all hard grinding wheels, it is higher than bonded abrasive products processing grinding ratio that its general character shows, grinding force is few, and grinding heat is also little. Meanwhile, because of the existence form of its working lining individual layer abrasive material, comparing with ceramic bond super-hard material emery wheel, resinoid bond extra hard material grinding wheel, cutting is sharp, grinding efficiency is high, it is whole to be excused from a college course in grinding operation, be easy to chip removal; Electroplating technology can be manufactured the emery wheel of shape face complexity, abnormity, and conformality is good, machining accuracy is high. Therefore, electroplate extra hard material grinding wheel and be widely used at automobile, LED, glass industry, such as automobile engine crankshaft grinding, sapphire cut, hand-set lid glass processing etc. The technological equipment of electroplating extra hard material grinding wheel, generally only needs the mini-plant such as dc source, electroplating bath, and manufacturing process is simple, cost is low. But, adopt existing equipment and technique manufacture high accuracy, long-life plating extra hard material grinding wheel can not meet the demands, urgently develop new equipment and technique.

Upper sand is an important procedure in electroplating abrasion wheel manufacturing process, and upper sand method mainly contains sand etc. in stucco method, sand buring method, suspension. For emery wheel more than diameters 400mm, adopt sand buring method more. Sand buring method is existing super hard abrasive to be trapped among to the external arc surface of emery wheel, and then buries sand method in the one of the emery wheel profile that will electroplate. Bury the thickness that the floating sand that exists in sand process, folded sand phenomenon have changed abrasive material, individual layer abrasive material becomes multilayer. Floating sand, folded sand cause abrasive material surface rough and uneven in surface, and cylindrical, face size precision cannot keep. In addition, floating sand, folded sand can make grinding-wheel grinder bed of material surface occur high point, will cause the circular runout of grinding operation medium plain emery wheel if do not repair, and cause surface of the work to occur the grinding failure such as burn, shake line. Mostly the finishing of high point is to use diamond roller to carry out large-area finishing to grinding wheel cylindrical arc, is not singly the partial trim in high some region. Such finishing mode is not only repaiied the height point of the grinding-wheel grinder bed of material, and part abrasive particles of other non-high points also can " be scabbled ", and emery wheel has the risk being lowered service life. The current density that existing sand buring method allows is generally no more than 0.8A/dm², for up to 3h～4h. The conventional sand mode of unloading is to use deionized water or plating solution to rinse abrasive material surface, and the hand-held water ladle that fills with plating solution or deionized water slowly waters to abrasive material, to remove the abrasive material of the coating not being adsorbed on. Bury sand current density little, only tens microns of the nickel dams of grinding wheel base body surface deposition, nickel dam is only faint absorption to abrasive material, does not also plate. Therefore, the intensity of water ladle cast is unsuitable too high, otherwise abrasive material can come off. The time that in the production process of existing superhard material electroplating abrasion wheel, upper sand (burying sand) and thickening expend has occupied 70%～80% of whole activity time, the sand time in shortening or/and the thickening time be the key of raising electroplating abrasion wheel production efficiency.

Utility model content

In order to overcome the defect of prior art, the utility model provides a kind of upper sand device of electroplating extra hard material grinding wheel of manufacturing.

Based on above-mentioned purpose, the utility model is taked following technical scheme:

Manufacture and electroplate the upper sand device of extra hard material grinding wheel, comprise sand launder, motor frame and be positioned at sand launder and bottom is provided with the upper sand base plate of universal wheel; Wherein, upper sand launder is positioned at motor frame, and the center of upper sand launder is provided with slot; The top of motor frame is provided with motor, and upper sand base plate is provided with circular sand ring set, is provided with some vibrating heads in sand ring set, the center of upper sand base plate is vertically provided with rotating shaft, and upper sand base plate can rotate with rotating shaft, insert in slot the bottom of rotating shaft, and the top of rotating shaft is connected with motor.

The utility model is in upper sand process, and vibrating head keeps vibration, and upper sand base plate keeps rotation, greatly shortened the upper sand time, and the current density maximum allowing in upper sand process is 2A/dm²。
