The combined grinding wheel device breaks through the traditional thought that the integrity of the grinding wheel needs to be guaranteed in the grinding wheel structure design, and the excircle surface of the grinding wheel is provided with through holes and a groove. Grinding fluid enters a radial groove via the upper through holes; then the grinding fluid enters a periphery groove via a gap between the periphery structural part I and the periphery structural part II and flows in the groove so as to strengthen heat transfer for a grinding arc area; the grinding fluid enters a side surface grinding arc area via side through holes; and integral heat transfer effect can be improved by 50% so as to better lighten grinding burn of material hard to process.
Description
Technical field
The present invention relates to a kind of combinated grinding wheel device for strengthening heat convection.
Background technology
The energy that grinding consumes enters workpiece surface in the mode of grinding heat, causes the variations in temperature on top layer, if the grinding fluid cooling is insufficient, can cause workpiece surface to produce Grinding heat injury, serviceability and the life-span of infringement workpiece.Say from grinding wheel structure, present most of grinding wheel cylindrical surface is a complete cylindrical surface, at grinding arc area grinding wheel cylindrical surface and surface of the work close contact, so that grinding fluid can't fully enter into grinding arc area and carries out the Convective heat tranfer cooling workpiece in grinding process.
For improving the heat convection effect, publication number is that the patent " intermittent grinding ceramic abrasive wheel " of CN201098848 is provided with the radial opening groove at the peripheral position of emery wheel, and the change continuous grinding is intermittent grinding; Publication number is that the patent " Discontinuous Grinding Wheel with Multi-porous Grooves " of CN2355847Y has many skewed slots wide at the top and narrow at the bottom at grinding wheel cylindrical and abrasive wheel end face.Although open the heat convection effect that radial slot can appropriateness increases grinding fluid at wheel face, but for guaranteeing grinding efficiency, radial slot small-sized, grinding fluid flows insufficient in groove, when the grinding wheel cylindrical zone between radial slot entered grinding arc area simultaneously, grinding fluid still can't enter grinding arc area.
For pottery or resin bond wheel, fluting has destroyed the integrality of emery wheel at grinding wheel cylindrical surface fluting, can cause the loss of grinding process medium plain emery wheel to increase, even the fragmentation of emery wheel; But along with the use of Metal Substrate plating and soldering superabrasive wheel, grinding wheel base body intensity obtains greatly to improve, and therefore need to break through the traditional design thinking of grinding wheel structure integrality.Present grinding wheel base body and cylindrical are as a whole in addition, and along with abrasive wear in the emery wheel use procedure arrives limiting value, emery wheel needs integral body to scrap replacing, but grinding wheel base body is intact; Integral body is scrapped will increase the emery wheel cost.
Summary of the invention
The present invention is for alleviating Grinding heat injury in the grinding process, strengthen the heat convection of grinding arc area, reduce the manufacturing cost of Metal Substrate emery wheel, a kind of combinated grinding wheel device for strengthening heat convection is provided, this has installed in Metal Substrate grinding wheel cylindrical surface design complicated trench structure, both guarantee grinding efficiency, increased again the convection current cooling effect of grinding fluid; And this device with grinding wheel base body and excircle part separately is designed to unified structure with excircle part, thereby when abrasive wear during to limiting value, only needs replacing cylindrical structure and needn't change grinding wheel base body, has reduced cost, has improved efficient.
Purpose of the present invention adopts following technical proposals to realize:
A kind of combinated grinding wheel device for strengthening heat convection, it comprises grinding wheel base body, and grinding wheel base body is installed outer rim structural member I and outer rim structural member II from inside to outside successively, and outer rim structural member I is connected hinged bolts to connect with outer rim structural member II.
Described outer rim structural member I bottom surface is distributed with at least one circumferential slot and many radial slots or skewed slot, and the upper surface both sides are provided with the upper through hole that radial slot or skewed slot with the bottom surface link, and the side has side through hole, and electroplate or the soldering super-hard abrasive bottom surface and side.
Described outer rim structural member II bottom surface is distributed with at least one circumferential slot and many radial slots or skewed slot, and the upper surface both sides are provided with the upper through hole that radial slot or skewed slot with the bottom surface link, and the side has side through hole, and electroplate or the soldering super-hard abrasive bottom surface and side.
The circumferential slot of described outer rim structural member II bottom surface and the circumferential slot of outer rim structural member I bottom surface are interspersed.
Beneficial effect: the present invention has broken through the conventional thought that needs to guarantee the emery wheel integrality in the grinding wheel structure design, at grinding wheel cylindrical surface design through hole and groove.Grinding fluid enters radial slot by upper through hole, enter circumferential slot by the space between outer rim structural member I and the outer rim structural member II, and in groove, flow, thereby grinding arc area is carried out enhanced heat exchange, grinding fluid also enters the side grinding arc area by side through hole, the overall heat exchange effect can improve more than 50%, alleviates preferably the grinding burn of difficult-to-machine material.

Wherein: 1 outer rim structural member I, 2 outer rim structural member II, 3 grinding wheel base bodies, 4 hinged bolts, 5 articulation holes, through hole on 6,7 side through hole, 8 radial slots, 9 circumferential slots, 10 workpiece, 11 front jet pipes, 12 lateral jet pipes.
The specific embodiment
Be described further below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of combinated grinding wheel device for strengthening heat convection, it comprise be provided with articulation hole 5 grinding wheel base body 3(as shown in Figure 2), grinding wheel base body 3 is installed outer rim structural member I 1 and outer rim structural member II 2 from inside to outside successively, and outer rim structural member I 1 is connected with outer rim structural member II and is adopted hinged bolts 4 to connect.
There is 1 circumferential slot 9 described outer rim structural member I 1 bottom surface central authorities both sides, the bottom surface is distributed with many radial slots 8, and the upper surface both sides have upper through hole 6 and the radial slot 8 of bottom surface to link, and the side has side through hole 7, electroplate or the soldering super-hard abrasive bottom surface and side, such as Fig. 3 (a) with (b).
There are 2 circumferential slots 9 in described outer rim structural member II 2 bottom surface central authorities, the bottom surface is distributed with many radial slots 8, and the upper surface both sides have upper through hole 6 and the radial slot 8 of bottom surface to link, and the side has side through hole 7, electroplate or the soldering super-hard abrasive bottom surface and side, such as Fig. 4 (a) with (b).
In use, wheel grinding processing work 10, as shown in Figure 5, front jet pipe 11 sprays grinding fluid to grinding arc area, the grinding fluid that front jet pipe 11 sprays can enter into grinding arc area along circumferential slot 9 by the gap of outer rim structural member I and II, carries out heat convection.Simultaneously, lateral jet pipe 12 sprays grinding fluid to the upper through hole 6 of outer rim structural member I and II, grinding fluid enters radial slot 8 by upper through hole 6, at the grinding arc area heat convection, and grinding fluid enters the side grinding arc area by side through hole 7 and carries out heat convection, thereby strengthen the heat convection effect of grinding arc area, alleviate Grinding heat injury.
After super-hard abrasive reaches wear limit rating, can change outer rim structural member I and II, and need not to change grinding wheel base body, thereby reduce use cost.
