Abstract
The invention discloses a polishing wheel containing fiber ropes. A polishing disk of the polishing wheel is composed of the fiber ropes, and the fiber ropes are bound by binder. By regulating the proportion between the fibers and the binder, the polishing effect and grinding efficiency of the polishing wheel can be controlled.
Description
Technical field
The present invention relates to a kind of polishing wheel of fibre-bearing rope, belong to grinding tool field.
Background technology
There is following defect in the various polishing wheels of current making: 1. polishing efficiency is low, as fiber crops wheel (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.
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 and 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.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of new polishing wheel.
Above-mentioned purpose of the present invention is achieved by the following technical solution: a kind of polishing wheel of fibre-bearing rope, and the polishing disk of described polishing wheel is comprised of cordage, and described cordage is bonding by binding agent.
Cordage in the present invention comprises conventional meaning line, the elongated thing that can be tortuous arbitrarily made from silk, cotton, fiber crops, glass fibre: silk thread.Cotton thread.Coil.Wire rod.Cotton rope.Also the rope that comprises conventional meaning, generally has the kinds such as plastic ties, the rope made of hemp, nylon rope, cotton cord.Along with industrial fast development, rope is turned round to knit by before several strands and is become two strands or two strands and turn round and be woven in together above, and material can be used, the fibers such as fiber crops, palm fibre, polypropylene fiber silk, dacron thread, cotton yarn, nylon yarn, glass fiber.Cordage in the present invention can be common commercially available cordage.
In the present invention, the fiber of described cordage can be natural fiber, and nature fiber original or that directly obtain on the plant of cultivation, on the animal of artificial feeding, includes but not limited to string, animal origin, mineral fibres.In concrete example of the present invention, described natural fiber is selected from seed fiber, as cotton, kapok etc.; Or leaf fibre, as sisal hemp, abaca etc.; Also or fasciated fiber, as ramie, flax, hemp, jute etc.In another example of the present invention, described natural fiber is selected from hair and silk, such as sheep's wool, goats hair, camel hair, the rabbit hair, yak hair or mulberry silk, tussah silk etc.Natural fiber described in the present invention can also be the recycled fiber of those Mian ﹑ Ma ﹑ Mao ﹑ silks.In the present invention, the fiber of described cordage can also be artificial fiber, includes but not limited to nylon fiber or glass fibre.
In the present invention, binding agent can be phenolic resins, urea aldehyde, melamine resin, epoxy resin or inorganic binder etc., also can be phenolic resin modified, the phenolic aldehyde that comprises the modifications such as urea aldehyde, melamine resin, epoxy, acrylic acid, consumption of binder is raw material gross mass 20-50%.
In the present invention, the mass fraction of cordage is 70-99%, and the mass fraction of binding agent is 1-30%.Within the scope of this, the mass fraction of cordage can be 75%, 80%, 85%, 90%, 95%, 99% etc., and the mass fraction of binding agent can be 1%, 5%, 8%, 10%, 15%, 20%, 25%, 30%.
In the present invention, adopt the benefit of cordage to be, the cordage blackout of can not feeling like jelly in the process of grinding; Cordage can strengthen structural strength as reinforcement again simultaneously.
The surface grooves that the favourable part of the present invention is to utilize the stereochemical structure of cordage itself to form is more conducive to grinding, moves back bits and heat radiation, simultaneously for new provides condition from sharp crazing development.Thereby the circular configuration of cordage itself allows again and between each root rope, is bound to form certain hole in forming process and forms being conducive to grinding, moving back the structure of bits and heat radiation of end face.In the present invention, can also in cordage, add sisal hemp crude fibre, not only increase rubbing down effect but also reduce costs.
Polishing wheel of the present invention can adopt two kinds of typical surface structures: plane polishing wheel and circumference polishing wheel.As described in Fig. 1 or 2.Fig. 3 illustrates the microstructure of polishing wheel.Binding agent combines cordage securely.Fig. 4 is the another kind of form microstructure schematic diagram of polishing wheel.During making plane polishing wheel, be simultaneously stained with back of the body lid, while making circumference polishing wheel, without the back of the body, cover.In the present invention, back of the body lid can be glass lid, sisal hemp etc.
