Abstract
The utility model relates to a heating split ring device of a double bearing outer ring. The output end of a high-frequency heater is connected with a closed heating coil; the heating coil is sleeved at a split opening of the double bearing outer ring; the split opening is electrified and heated so as to increase the brittleness; and the double bearing outer ring is split by a mechanical splitting tool at a preset temperature of 250-300 DEG C. The heating split ring device has the characteristics that a high-frequency heater is used for rapidly heating based on the property of blue brittleness of metal materials, and the ring is split under the condition that the hardness of materials is not changed; the working efficiency is improved, and the section of the ring is smooth and is unlikely to deform; and the qualified rate of the split ring is above 95%.
Description
Technical field
The utility model relates to a kind of process equipment of rolling bearing, specifically, is that coil apparatus is cutd open in the heating of a kind of double-row bearing outer ring.
Background technology
Rolling bearing is that the axle of running and the sliding friction between the axle bed are become rolling friction, thus the mechanical organ of a kind of precision of the loss of reducing friction.Rolling bearing generally is made up of inner ring, outer ring, rolling element and retainer four parts, and the effect of inner ring is to match to merge with axle to rotate together with the axis; The outer ring effect is to match with bearing block, plays a supportive role; Rolling element is uniformly rolling element to be distributed between inner ring and the outer ring by means of retainer, and its shape size and quantity directly affect the serviceability and the life-span of rolling bearing; Retainer can make rolling element evenly distribute, and prevents that rolling element from coming off, guiding rolling element rotation lubricate.NNC series bearing just can't carry out the routine assembling because Internal and external cycle all is two rib designs.In order to guarantee the precision of a whole set of bearing, in process of production, the outer ring is whole processing, just must the outer ring cut open and can assemble before the assembling again.Like Fig. 2, in cuing open the circle process, to utilize outmoded mechanical device to enclose from indentation, there and separate, this method of operating not only can make the circle groove place fluffing that obtains, and the section plane degree is bad, encloses yieldingly, and the one-tenth rheogameon qualification rate that obtains has only 70%, and production efficiency is low.When being warming up to 250 ~ 300 ℃, the plasticity of mild steel reduces.This phenomenon is called the blue shortness phenomenon.Utilize the blue shortness phenomenon, be equipped with thermatron again, the circle groove place of outer ring is heated, its fragility is increased with high frequency heating machine; Just can the outer ring of NNC series bearing be cut open from the circle groove.
Summary of the invention
The utility model relates to the heating of a kind of double-row bearing outer ring and cuts open coil apparatus, and its objective is provides a kind of time weak point, fast, the measured adding apparatus of matter of heating, and the ropy problem of circle is cutd open in the heating that solves the double-row bearing outer ring.
The technical scheme that the utility model adopts is: coil apparatus is cutd open in the heating of a kind of double-row bearing outer ring, comprises that double-row bearing outer ring, high frequency heating machine and machinery dissect instrument, and the circle groove place of double-row bearing outer ring is with heater coil; High frequency heating machine is placed in a side of double-row bearing outer ring; The output of high frequency heating machine connects heater coil, and the energising heating increases its fragility; Machinery dissects the outside that instrument places the double-row bearing outer ring, and the outer ring of double-row bearing is cut open.
Further improvement as the utility model; The double-row bearing outer ring is two rib structures; On the double-row bearing outer ring, be processed with inboard circle groove and outside circle groove, the V-shaped structure in cross section of inboard circle groove and outside circle groove, heater coil is enclosed within on inboard circle groove and the outside circle groove.
As the further improvement of the utility model, it is a kind of chisel with taper sword that machinery dissects instrument, and machinery dissects instrument and cuts the double-row bearing outer ring open through inboard circle groove and outside circle groove.
The advantage of the utility model is: utilize the high frequency heating machine Fast Heating, under the situation that does not change material hardness, circle is cut open; Both improved operating efficiency, can make again the circle section smooth, not yielding, cut open the circle qualification rate reach more than 95%.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the operational diagram of high frequency heating machine;
Wherein: 1-double-row bearing outer ring, the 2-heater coil, the 3-high frequency heating machine, 4-machinery dissects instrument, the inboard circle of 11-groove, 12-outside circle groove.
The specific embodiment
Give below and close accompanying drawing and embodiment is further described the utility model.
Embodiment is like Fig. 1, shown in 2, and present embodiment provides the heating of a kind of double-row bearing outer ring to cut open coil apparatus, comprises that double-row bearing outer ring 1, high frequency heating machine 3 and machinery dissect instrument 4; The circle groove place of double-row bearing outer ring 1 is with heater coil 2, and high frequency heating machine 3 and heater coil 2 are placed in a side of double-row bearing outer ring 1, and the output of high frequency heating machine 3 connects heater coil 2; The energising heating; When reaching 250 ~ 300 ℃ of predetermined temperature, the fragility of double-row bearing outer ring 1 increases, in other words; Inboard circle groove 11 strengthens with the notch sensitivity of outside circle groove 12, dissects instrument 4 with machinery and is easy to cut and do not damage them open other positions.On double-row bearing outer ring 1, be processed with inboard groove 11 and the outside circle groove 12 of enclosing, the V-shaped structure in cross section of inboard circle groove 11 and outside circle groove 12.
It is a kind of chisels with taper sword that machinery dissects instrument 4.
The beneficial effect of present embodiment is: under the situation that does not change material hardness, circle is cut open; Both improved operating efficiency, can make again the circle section smooth, not yielding, can make cut open the circle qualification rate reach more than 95%.
