Detailed description of the invention
Following according to Fig. 1 to Fig. 3, and embodiments of the present invention are described.This explanation is not restriction embodiments of the present invention, and is the one of embodiments of the invention.
As shown in Figure 1 to Figure 3, according to the manufacture method of a foaming emery wheel of the present invention, comprise: a foaming emery wheel raw material is positioned in an accommodation space of a constant voltage mould (step S10); By the constant voltage containment member in this constant voltage mould, constant voltage sealing is imposed to this accommodation space, and make this accommodation space be pressure constant state (step S20); And under this pressure constant state, maturation process given to this foaming emery wheel raw material in this accommodation space and form a foaming emery wheel (step S30).
Refer to Fig. 1, and Fig. 2 and Fig. 3 is consulted in cooperation, the detailed embodiment of one embodiment of the invention will be described below.
First, a constant voltage mould 100 is positioned in a baking oven (not shown) and gives pre-temperature process (step S05) with the temperature of 36 to 40 DEG C.Then, as shown in Figure 1, the emery wheel raw material M that foams (comprising the abrasive material, blowing agent etc. that mix) is positioned in an accommodation space S of this constant voltage mould 100 (step S10).Preferably, this foaming emery wheel raw material M comprises the blowing agent of two-liquid type polyurethane, and this blowing agent is solidified forming by cross-linking reaction.Due to the temperature process in advance of this constant voltage mould 100, therefore when the blowing agent in this foaming emery wheel raw material M is positioned over this constant voltage mould 100, the heat energy absorbing this constant voltage mould 100 is carried out cross-linking reaction lentamente, and abrasive material can be made to be uniformly distributed.
Then, as shown in Figure 2, by this constant voltage containment member 1, constant voltage sealing is imposed to this accommodation space S, and make this accommodation space S be pressure constant state (step S20).Specifically, this constant voltage containment member 1 comprises a seal 11 and and executes heavy mail 12.The seal 11 is seal up in this accommodation space S, is hedged off from the outer world to keep this accommodation space S and this foaming emery wheel raw material M.This is executed heavy mail 12 and is connected to the seal 11 and in order to provide fixed weight in the seal 11, and makes the seal 11 can impose constant pressure to this foaming emery wheel raw material M.Certainly, the present invention is not as limit, and this is executed heavy mail 12 and also can be combined as a whole with the seal 11, and imposes constant voltage sealing to this accommodation space S.Then, this constant voltage mould 100 being placed with this foaming emery wheel raw material M is given heat treatment (step S25) with the temperature of 30 to 50 DEG C.
Then, under this pressure constant state, hold temperature to this foaming emery wheel raw material M in this accommodation space S with 30 to 50 DEG C within 48 to 72 hours, carry out maturation process and form a foaming emery wheel (step S30), complete cross-linking reaction is produced to enable the blowing agent of the two-liquid type polyurethane in this foaming emery wheel raw material M, and abrasive material is uniformly distributed in blowing agent, emery wheel quality is easily controlled.Specifically, this constant voltage containment member 1 be along with the volume of this foaming emery wheel raw material M to expand with the growth of the time of maturation process produced a pushing force F and mobile (such as: move axially, as shown in Figure 3), to make this accommodation space S remain pressure constant state.
Finally, then this foaming emery wheel is taken out (step S40) in this constant voltage mould 100, and removed the peel process (step S45).After heat treatment, this foaming emery wheel can cool from outside to inside gradually, makes the outer surface of this foaming emery wheel produce one deck skinning and is unfavorable for grinding, the abrasive material of foaming emery wheel and pore can be made to expose and can play best grinding effect by peeling process.For example, peeling is treated to and is immersed in oil to make skinning be separated.
Specifically, this foaming emery wheel density can by blowing agent and abrasive material etc. foam the addition of emery wheel raw material M and this execute the weight that heavy mail 12 applies and adjust.Because blowing agent foams in this accommodation space S, when the addition of foaming emery wheel raw material M is fewer, the expansion rate in mould is just higher, and the pore of this emery wheel is therefore just large, and then the possibility of chip blocking pore when can reduce grinding.Otherwise if to execute the weight that heavy mail 12 applies heavier for this, M is larger in the oppressive force suffered by foaming process for this foaming emery wheel raw material, and the expansion rate in mould is just lower, and then can reduce the rate of wear of foaming emery wheel.
Via the technology used in the present invention means, in processing procedure, only need mix and blend and heat, therefore equipment cost can be reduced without the need to the mixing roll that uses the price used required for traditional emery wheel high and vulcanizer, and do not need to use extra equipment in standing process, thus can reach in enormous quantities, low-cost production.
Above describing is only preferred embodiment of the present invention and illustrates, is allly skillful in this those skilled in the art when can do other all improvement according to above-mentioned explanation, but these change and still belong in the spiritual and the scope of the claims that defines of invention of the present invention.
