A metal core sleeve can be embedded in manufacturing the emery roll of the present invention. The metal core sleeve can raise the machining accuracy of the emery roll to bring facility to installation and use.
Description
The present invention relates to a kind of rice milling resin roller that is suitable for using in the rice milling machine and preparation method thereof.
Rice-milling roller is to be used for rice milling machine to the cereal accurately machined important accessory of milling.Had ceramic rice-milling roller in the prior art, the pottery rice-milling roller is by clay, silicate starting materials such as feldspar are made wedding agent and are mixed mutually with abrasive material, drying, roughing, high temperature sintering forms, its main drawback is: the production cycle is long, the temperature height that burns till, energy consumption is big, the sand roller easily cracks and is out of shape when firing, scrap rate is higher, geometric accuracy is low, because the wedding agent processability is relatively poor, this sand roller fragility is big, and the moulding of sand roller need keep bigger roller wall thickness, so raw material consumption is many, and be difficult on the sand roller, offer hole slot and thread groove and since when making can not with the hardware connecting shaping, this sand roller installs also for processing and use has brought inconvenience.Also have resin wheel in fields such as mechanical workouts, resin wheel is that wedding agent and abrasive mixed system form with single resol, its toughness is low, poor impact resistance, because husk rice adds man-hour, grain is bigger to the surging force of sand roller, therefore exists rapid wear with this kind resin sand roller as rice-milling roller, the problem that work-ing life is too short.
The objective of the invention is to provides a kind of improved rice milling resin roller and preparation method thereof at the deficiency of above-mentioned existence, and this rice milling resin roller not only is easy to make and moulding, and excellent property, long service life.
Rice milling resin roller of the present invention is realized by following technical scheme: it is to be formed through mixing press process by following proportion raw material:
3～60 parts of 3～40 parts of Resins, epoxy of 100 parts of resol of abrasive material or urethane
1～100 part of terra alba, density 1.98～2.65 feeds intake.
In the above-mentioned prescription, abrasive material is a silicon carbide abrasive, i.e. C16～C120, and abrasive grain is 16～120 as requested, granularity commonly used is 24～60; Abrasive material also can be the compound of silicon carbide and brown corundum, and its blended proportioning is: 45～60 parts in silicon carbide, and 40～55 parts in brown corundum, wherein terra alba plays enhancement as filler; Resins, epoxy is used for modification, has the agglutinating of reinforcement function.
Optimum material proportion of the present invention is:
4.0～8.2 parts of 7～20 parts of Resins, epoxy of 100 parts of resol of abrasive material or urethane
3.0～7.0 parts of terra albas.
Making method of the present invention is finished by following scheme: get each raw material stirring by proportioning and mix, rescreen loose weighing and go into mould, compression moulding then, the hardening treatment of once heating after the demoulding, 110～130 ℃ of the temperature of heating, time is 7～9 hours, after the hardening treatment of once heating, the sand roller is carried out precision work, carry out the secondary heating hardening treatment after the precision work, 180～200 ℃ of the temperature of heating, 7～9 hours time.
The present invention compared with prior art has following positively effect: 1, added Resins, epoxy in wedding agent, the intensity and the anti-impact force performance of rice-milling roller are improved greatly, it is long service life not only, and sand roller wall is thin, saves abrasive material, and the self-sharpening of sand roller is good, it is strong to have the husk rice ability, the unit-hour output height, and processing quality is good, broken rice rate is low, the machining load features of smaller; 2, rice-milling roller of the present invention is only handled through twice low-temperature stiffening, not only energy consumption is low, and be difficult for cracking and being out of shape, yield rate height, especially this rice-milling roller can embed the metal core retainer plate of having processed in advance when making, and can be combined into one with rice-milling roller, the precision work that this both can be convenient to the sand roller makes it possess good geometric accuracy and balance quality, also is convenient to connecting of rice-milling roller and arbor, give to install and use and brought convenience, and make its operation safer reliable; 3, making method of the present invention adopts the mode of twice hardening treatment of heating, its special-effect is, the hardening treatment of once heating, make the resin of rice-milling roller be in semi-cured state, this moment its intensity, toughness, hardness is not very high, be easy to its cylindrical and end face are carried out precision work, and offer difform spiral slot or straight trough, after precision work, again it is carried out the secondary heating hardening treatment, make the wedding agent completely solidified of rice-milling roller, compare with the working method of the hardening treatment of once heating, the present invention can make processing intensity and amount of finish descend greatly, thereby has reduced the cost of producing rice-milling roller.

Fig. 2 is the side-view of metal core retainer plate among Fig. 1.
Fig. 3 is the full sectional view of another embodiment of the present invention.
Fig. 4 is the A-A sectional view among Fig. 3.
First embodiment proportioning raw materials of the present invention is:
6.0 parts of 12.6 parts of Resins, epoxy of 100 parts of resol of silicon carbide C36
6.4 parts of density 2.35 sand roller hardness N that feed intake of terra alba.
Working method as previously mentioned, the hardened temperature of wherein once heating is 110～120 ℃, the time is 8 hours, secondary heating hardened temperature is 190 ℃, the time is 8 hours.The shape of sand roller 1 is tubular, be inlaid with metal core retainer plate 2 in its endoporus, for the metal core retainer plate is combined firmly with the sand roller, on the cylindrical of metal core retainer plate, offer many grooves 3, and along circumferentially uniform, as shown in Figure 1, 2, in addition, according to the requirement of grain processing Technology, on the cylindrical of sand roller, can offer axial straight trough, or big helical pitch spiral slot.The another kind of structural shape of sand roller is shown in Fig. 3,4, and sand roller 1 is long tubular, and its endoporus two ends are inlaid with metal core retainer plate 2, offer longitudinal slot 4 on the sand roller, and this sand roller can use in jet-air rice polisher.
