Description

Flap wheel and manufacturing have the method for the flap wheel of disc-shaped carrier
Technical field
The present invention relates to the method that a kind of manufacturing has the flap wheel of disc-shaped carrier, wherein the overlapping abrasive sheet of many shide shapes sticks on the carrier section section of annular, this carrier section section concentrates on the rotation of flap wheel, wherein this carrier section section is made of amorphous thermoplastic plastic, especially is made of ABS.In addition, the invention still further relates to such flap wheel.
Background technology
Known flap wheel has the fin carrier, and it is made of fabric or fibre-reinforced synthetic timberland usually, or is made of the thermoplastic's material that does not strengthen.On carrier, the abrasive sheet shide shape that is made of abrasive media sticks on the base overlappingly.Be known that the carrier section section of carrying abrasive sheet is mostly perpendicular to rotation.In order more flatly to grind, carrier section section tilts in a kind of special flap wheel, so that when the abradant surface that tilts keeps flat, stretching screw to a certain extent can be outstanding from the surface to be processed.
Will give much attention to when using flap wheel, carrier and/or the adhesive that is positioned at the abrasive sheet below do not contact with workpiece.This can pollute and damage workpiece to be processed.As long as stick on abrasive sheet on the carrier section section in the radial direction from the outer cover upper process of carrier, then it firmly shielding tool contact with carrier preventing.Certainly, the wearing and tearing of abrasive sheet can make the reduced of flap wheel, so that the outer cover of carrier can be exposed below abrasive sheet.Therefore in practice, mostly can only use 1/3rd of fin covering.
Described shortcoming overcomes in practice in the following manner, namely by carrier is remained on the suitable edge rotatably, in order to scalp outstanding material from the carrier.Be known that this way is that carrier is repaired or pruned.By remove the part of projection with cutting way, can realize again grinding, and needn't worry that carrier contacts with workpiece.Can the obvious larger part of fin covering be used by this way.Be known that in order to realize defined finishing, and obtain the carrier edge of clean turning, use thermoplastic (especially amorphous thermoplastic is such as ABS) as carrier, to replace fibre-reinforced plastics
But, when pasting this carrier that is consisted of by amorphous thermoplastic, can only use the adhesive that makes two hardenings by cooling in a plurality of, because these adhesive can guarantee that abrasive sheet remains on the carrier especially goodly.But it is relatively low that the shortcoming of these abrasive sheets is viscosity, if adhesive is not fully sclerosis also, its meeting is so that slippage occurs in new stick-on abrasive sheet easily when mechanical load or wrong supporting, on the other hand, hardly may be with viscosity adjustment to enough high, because adhesive must transport and mix with curing agent.In order better to aspirate and dosage, can not reduce this viscosity also by heated nozzle, because improve temperature sclerosis is accelerated.
In other words, if be to paste the carrier that amorphous thermoplastic consists of, and use the system of heat hardening on the basis of epoxy resin, then the adhesion meeting on carrier of adhesive and abrasive sheet is very poor.This can make sticking water layer and abrasive sheet and carrier get loose, thereby increases accident hazard.Therefore, the adhesive of heat hardening still is not suitable for making the flap wheel that can prune so far.
Summary of the invention
Thus, the objective of the invention is, propose a kind of method of making described type flap wheel, wherein abrasive sheet can be fixed on the carrier with simple and reliable mode and method.In addition, the objective of the invention is, propose a kind of corresponding flap wheel.
These purposes are achieved by the method with claim 1 feature and the device with claim 6 feature.Other especially preferred structural scheme of the present invention is illustrated in the dependent claims.
Basic concept of the present invention is, changes the surface of carrier section section before being stained with, with the firm stop of the adhesive of guaranteeing heat hardening.Described change is called activate, and can realize in a different manner.According to activate of the present invention, the adhesive of heat hardening spreads upon on the activate surface of carrier section section.Then, the abrasive sheet placement with by being pressed on the carrier section section that is provided with adhesive.
Its major advantage is that the adhesive of heat hardening can stick on the surface of carrier better by activate.In the application's meaning, activate refer to machinery, physics and/or chemical aspect processing, make rough surface or coating be set by described processing, this coating can be improved the adhesiveness of the adhesive of heat hardening.The utilized contact surface of adhesive on carrier section section improved on coarse surface, and coating has changed its attribute.In addition, also can remove by activate and stick to lip-deep foreign matter.Can improve adhesive adhesiveness from the teeth outwards by activate.By by activate of the present invention, the surface of the carrier that is made of ABS is that the adhesive of application of heat sclerosis is prepared.
Therefore, the minimum explosion value (Mindestsprengwert) that has obvious raising by flap wheel of the present invention.For example when the diameter of flap wheel is 115mm, obviously surpassed the minimum explosion value of required 140m/s.Although used the adhesive of heat hardening, the abrasive sheet of stickup still can firmly remain on the carrier of activate.In addition, can not see again that or not smooth of adhesive and carrier peel off.When excess load, only have single abrasive sheet to get loose from carrier section section, this carrier section section is not almost damaged risk.
In addition, the adhesive of application of heat sclerosis also has obvious advantage in the production process of flap wheel.The adhesive of heat hardening hardens apparently higher than room temperature the time, especially hardens in 100 and 150 ℃ temperature range.The reaction of adhesive and its reaction time are relevant with temperature, and therefore can control by temperature.
Therefore, compare with the adhesive system of hardening by cooling, the adhesive system of heat hardening can be rendered in the production process with the mixed form that makes.Hybrid chamber then no longer needs.Can when making adhesive, (in first being processed) just can regulate required uniformity in suppliers, and can come adjusting viscosity by for example inserts and/or average molecular weight.
Since relatively high to the tolerance of heat, so also can regulate by temperature the expectation viscosity of adhesive.The adhesive of heat hardening can aspirate and dosage by this way without problems.By the quick cooling on the abrasive sheet carrier, can improve at short notice the viscosity of adhesive, so that abrasive sheet can be carried nondestructively placement and glue can not extend on the carrier.
Another advantage of the system of heat hardening is even that in process of production long-time shut-down, it can not harden in by the element of its infiltration yet.Therefore, after stopping work, production process do not need to change these elements, for example nozzle with wasting time and energy.
In a preferred embodiment, come the surface of activated carrier section section by grinding, chemistry melting or corrosion.Each activation method easily automation carries out, and therefore is fit to produce in batches flap wheel.
According to the present invention, the activation on surface is preferably directly in process of production integrated.But the activation automation ground on surface carries out, although so that the job step of additionally carrying out is arranged, still can avoid the minimizing of production output.
Present major advantage of the present invention is, by at first made by way of the present invention can prune, at the flap wheel that thermoplastic makes up, it has the carrier section section of inclination.In this flap wheel, carrier section section tilts with the angle between 50 to 85 degree towards the rotation of carrier, and this angle is especially between 60 to 80 degree.Now this point is feasible, because the adherence force of the adhesive of heat hardening under machining state enough has sufficiently high viscosity in the large situation, so the abrasive sheet of placement can be stayed on its position and can be from slippage on the slope.This flap wheel with inclination carrier section section has very large advantage, and namely the abradant surface by tilting towards rotation makes possible bearing-surface become especially large, and maximum material covering also becomes especially large thus.By inclined orientation and bearing-surface that may be higher, the flap wheel with inclined geometric shapes has more obvious increment for the user.
By pressing the higher adhesive of viscosity used in the present invention, single abrasive sheet can be carried nondestructively when placing and remain on the inclined-plane, and avoids adhesive to spread before sclerosis.With comparing by application of the present invention of the adhesive of heat hardening, be not suitable for abrasive sheet is sticked on the abrasive sheet carrier of inclined orientation for the material that is stained with the hardening by cooling that the carrier that is made of ABS uses so far.
