Abstract
The utility model relates to milling and grinding machine tools, in particular to abrasive belt grinding devices of milling and grinding machine tools. An abrasive belt grinding contact wheel of a milling and grinding machine tool comprises a steel core wrapped by polyurethane rubber, the outer surface of the polyurethane rubber is provided with a helical groove, and the helical groove with a 60-degree lead angle is 15mm in width and 5mm in depth. By means of the abrasive belt grinding contact wheel of the milling and grinding machine tool, grinding efficiency of low-power sulfur printing plate blank can be effectively improved, machining cost is reduced, and surface quality of the plate blank is improved.
Description
Technical field
The utility model relates to milling machine tool working, relates in particular to milling machine tool working sbrasive belt grinding equipment.
Background technology
Numerical control low power sufur printing sample milling machine tool working is the specialized nc machine tool that low power sufur printing sample (slab) is processed; According to the program that configures, blank automatically carries out obtaining carrying out low power sufur printing test with the surface after milling and the grinding cutting after getting into lathe.Grinding is to accomplish through the abrasive band.Contact wheel tightly the abrasive band is pressed in surface of the work, accomplish grinding through the high speed rotary of self and the feeding of workpiece.Contact wheel is two material parts, and fuse is a steel, outsourcing one deck polyurethane rubber.
There is following shortcoming in being used of this contact wheel and abrasive band in the process:
When 1, work in the abrasive band is to make circular motion, and linear velocity can reach 35m/s.Because the surface of contact wheel is the plane, in the high speed rotary course, form the gas wedge between abrasive band and the contact wheel easily, the frictional force between abrasive band and the wheel face reduces, and causes the abrasive band unstable, has reduced the grinding drag in abrasive band simultaneously.
2, stainless steel is a difficult-to-machine material, and small iron filings can adhere between the particle in abrasive band during grinding, greatly reduces the grinding efficiency of abrasive band particle, produces a large amount of heat simultaneously.Because the contact area of abrasive band and contact wheel is very big, heat can't spread, and causes the abrasive band overheated, and broken belt takes place easily, and processing cost obviously rises.
3, grinding efficiency is poor, and each grinding thickness can only reach 0.02mm.
4, add the vibrations in man-hour greatly, vexed car phenomenon (motor rotation blockage or abrasive band and contact wheel skid) often occurs, increased fault handling time, prolonged the slab process-cycle.
5, the steel slab surface after the processing is of poor quality, occurs the calcination shape easily, influences the testing result of low power sufur printing.
Summary of the invention
The utility model is intended to address the above problem, and a kind of milling machine tool working sbrasive belt grinding contact wheel is provided.The utility model can effectively improve the efficient of low power sufur printing slab grinding, cuts down finished cost, and promotes the slab surface quality.
For addressing the above problem, a kind of milling machine tool working sbrasive belt grinding of the utility model contact wheel, it comprises the steel core of outsourcing polyurethane rubber, and said polyurethane rubber outer surface has the groove shape of spiral, and helicla flute is 60 ° of lift angles, groove width 15mm, dark 5mm.
The utility model with the polyurethane rubber plane surface of outsourcing instead with the surface configuration of the groove shape of spiral; In the process that the drive abrasive band rotates at a high speed; Can avoid the generation of gas wedge; And eliminate the problem that the abrasive band is unstable and the grinding drag reduces that causes by the gas wedge, in the process, abrasive band stability significantly strengthens.Helicla flute has not only changed contact wheel and has crossed surface configuration; Also improved the elastic deformation amount of polyurethane rubber in the process; Not only the stability in abrasive band has strengthened, and grinding efficiency increases substantially, but brings up at present each maximum grinding 0.06mm by the grinding thickness of each 0.02mm.The raising of grinding efficiency has not only improved operating efficiency, also aspect energy-saving and cost-reducing, remarkable result is arranged.Spiral fluted exists, and has reduced the contact area of abrasive band and contact wheel, has improved the heat-sinking capability in abrasive band, has reduced the possibility of broken belt, has practiced thrift production cost.Shake for a short time in actual use, eliminate vexed car phenomenon basically, simultaneously the steel slab surface steady quality after the processing.
Description of drawings
Below, in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the utility model sketch map.
The specific embodiment
As shown in Figure 1, a kind of milling machine tool working sbrasive belt grinding contact wheel, it comprises the steel core 1 of outsourcing polyurethane rubber 2, and said polyurethane rubber outer surface has helicla flute 3, and helicla flute 3 dimensional parameters are 60 ° of lift angles, groove width 15mm, dark 5mm.
