Abstract
The invention discloses a preparation method for a polishing and grinding integrated wheel comprising a fiber rope and abrasive material. The preparation method comprises the steps that a circle of adhesive coats the fiber rope in a rolling mode, the abrasive material coats the fiber rope in a rolling mode and in a gravity sand coating mode, a sand rope winds around a die according to needs and then is placed inside a die cavity, and then the steps of pressing, forming and the like are carried out.
Description
Technical field
The preparation method who the present invention relates to the rubbing down integrated wheel of a kind of fibre-bearing rope and abrasive material, belongs to grinding tool field.
Background technology
The various rubbing down grinding tools of current making mainly contain three large classes and have following defect: 1. resin wheel---due to close structure, weak heat-dissipating, oil pressure moulding, dense structure.General resin bond wheel (bonded abrasive tool) is mainly to be formed through mixing, compression molding, heat hardening by abrasive material, resin adhesive, and the use of this class emery wheel exists such as defects such as the heating of the large cutting force of needs, workpiece are serious.Pore in porous grinding wheel (bonded abrasive tool) be generally in cure process by fill can be at the temperature higher than more than 130 degree the filler (as walnut shell, refined naphthalene etc.) of burn off (being carbonization) burn and form.Thereby but natural fiber also can lose efficacy under this operating mode in carbonization.
2. fiber crops wheel---polishing efficiency is low, as (which floor sisal hemp is sewed together, and only has end face to participate in grinding).Chinese patent CN1238254A discloses a kind of sisal fiber polishing wheel, discloses its preparation method to be: adopt needing machine that sisal hemp short fibre is made to felted stock, then by layer 2-4 sisal hemp felted stock through superimposed, be stitched into a kind of sisal fiber polishing wheel.There is following shortcoming in the sisal fiber polishing wheel prepared by this kind of method: one, because used sisal fiber length only has 4-12cm, thereby polishing wheel in use sisal fiber easily come off, shortened the service life of polishing wheel; Two, because of the restriction of needling density, can not guarantee can to combine closely in any position of polishing wheel, thereby also can affect the result of use of polishing wheel.
3. nylon wheel---abrasive material utilization rate is not high, thereby because the low heating of TG of nylon can cause softening causing, abrasive material hold is declined, so that abrasive material does not fully participate in grinding, does not just come off and causes waste; Also likely because feeling like jelly, pollute grinding workpiece surface simultaneously.
Chinese patent CN200410029879.9 has disclosed a kind of manufacture method of sisal fiber polishing wheel, and it is after the sisal fiber prescinding, synthetic resin and optional other plant and inorganic compound are evenly mixed, are dried, hot-forming.The polishing wheel that this method is produced is owing to being mold pressing but thering is no that material with holes so that total are very fine and close does not have space, thereby easily causes emery wheel surface temperature rising bonding agent inefficacy surface blackening in whole grinding process, the waste of raw material breaking releasing; Thereby grinding workpiece also can cause greatly the concentrated grinding workpiece surface of also likely polluting of stress by surface temperature rise simultaneously.
