Abstract
The utility model discloses Centering Roll lubrication system before a kind of punch machine of improvement, comprise roller and roll shaft, roller axis hole two ends are symmetrically arranged with recessed seam, from the inside to the outside spacer ring and gland are housed successively from recessed seam; The periphery of gland is provided with flange hole, and is connected with roller by bolt; The inner circle of spacer ring is provided with recessed seam, and from the inside to the outside graphite copper sheathing and back-up ring is housed successively, and roll shaft is installed in the axis hole of graphite copper sheathing and back-up ring.The utility model improves Centering Roll internal structure, uses graphite copper sheathing to replace bearing, makes the graphite in graphite copper sheathing play lubrication, significantly extends Centering Roll service life under the high temperature conditions.
Description
Technical field
The utility model relates to a kind of roll shaft lubrication system, is applicable to the lubrication of Centering Roll before punch machine, Centering Roll lubrication system before the punch machine of particularly a kind of improvement.
Background technology
Needing during existing seamless steel pipe operation, three row's Centering Rolls (often arranging 3) are set between punch to roll and supports and hold tightly push rod centering drilling/rolling steel pipe, in case eccentric during perforation.Centering Roll assembling rolling bearing, respectively assemble a set of circular cone roller bearing in the both sides of roll shaft, bearing inner ring is equipped with back-up ring, outside bearing, transparent cover is housed.Because centering roller device distance roll is near, temperature is high, and bearing is fragile, and cause roller not rotate, maintenance load is large.And frequently use high temperature resistant lubricating grease operating cost higher.
Utility model content
Technical problem to be solved in the utility model is the lubrication needs according to Centering Roll before punch machine, on the basis of high temperature resistant greasy property ensureing Centering Roll, extends the service life of Centering Roll.
For solving the problem, the technical solution adopted in the utility model is: Centering Roll lubrication system before a kind of punch machine of improvement, comprises roller and roll shaft, it is characterized in that, roller axis hole two ends are symmetrically arranged with recessed seam, from the inside to the outside spacer ring and gland are housed successively from recessed seam; The periphery of gland is provided with flange hole, and is connected with roller by bolt; The inner circle of spacer ring is provided with recessed seam, and from the inside to the outside graphite copper sheathing and back-up ring is housed successively, and roll shaft is installed in the axis hole of graphite copper sheathing and back-up ring.
Another technical scheme of the utility model is: Centering Roll lubrication system before a kind of punch machine of improvement, comprises roller and roll shaft, it is characterized in that, roller axis hole two ends are symmetrically arranged with recessed seam, installs spacer ring interference fit fix from two ends; The inner circle of spacer ring is provided with recessed seam, and from the inside to the outside graphite copper sheathing and back-up ring is housed successively, and roll shaft is installed in the axis hole of graphite copper sheathing and back-up ring.
The utility model has the advantages that and improve Centering Roll internal structure, reset spacer ring, and in spacer ring, arrange recessed seam, making graphite copper sheathing substitute bearing becomes possibility.In roller turn process, the phase mutual friction of graphite copper sleeve inner hole and roll shaft, the graphite flake that copper sheathing periphery is inlayed in many apertures plays lubrication, because graphite has heat-resisting quantity and good lubricity, significantly extends Centering Roll service life under the high temperature conditions.

Fig. 2 is the another kind of structure installment view of the utility model.
In figure: 1. roll shaft, 2. roller, 3. gland, 4. back-up ring, 5. graphite copper sheathing, 6. spacer ring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, see Fig. 1, Centering Roll lubrication system before a kind of punch machine of improvement, comprises roller 2 and roll shaft 1, the axis hole two ends of roller 2 are symmetrically arranged with recessed seam, from recessed seam, spacer ring 6 and gland 3 are housed from the inside to the outside successively; The periphery of gland 3 is provided with flange hole, and is connected with roller 2 by bolt; The inner circle of spacer ring 6 is provided with recessed seam, and graphite copper sheathing 5 and back-up ring 4 are housed from the inside to the outside successively, and roll shaft 1 is installed in the axis hole of graphite copper sheathing 5 and back-up ring 4.See Fig. 2, another technical scheme of the utility model is: Centering Roll lubrication system before a kind of punch machine of improvement, comprises roller 2 and roll shaft 1, and roller 2 axis hole two ends are symmetrically arranged with recessed seam, installs spacer ring 6 interference fit fix from two ends; The inner circle of spacer ring 6 is provided with recessed seam, and graphite copper sheathing 5 and back-up ring 4 are housed from the inside to the outside successively, and roll shaft 1 is installed in the axis hole of graphite copper sheathing 5 and back-up ring 4.
embodiment 1:now with Centering Roll lubrication system before 140 punch machines for example, describe in detail.As shown in Figure 1, a better embodiment of the present utility model, utilize roller 2 and the roll shaft 1 of former Centering Roll, cancel original bearing of assembling on roll shaft 1, the axis hole two ends symmetric extension of roller 2 is provided with two isometrical recessed seams, recessed seam internal diameter 20mm larger than shaft hole diameter, is convenient to spacer ring 6 and installs location.From recessed seam, spacer ring 6 and gland 3 are housed from the inside to the outside successively, spacer ring 6 periphery and roller 2 recessed seam inside diameter hoop face interference fit, in case spacer ring 6 and roller 2 relatively rotate; The interior fenestra of spacer ring 6 is provided with recessed seam, graphite copper sheathing 5 and back-up ring 4 are housed from the inside to the outside successively, the periphery of graphite copper sheathing 5 and the recessed seam inside diameter hoop face interference fit of spacer ring 6, in case graphite copper sheathing 5 and spacer ring 6 relatively rotate, keep and roller 2 synchronous axial system; The periphery of back-up ring 4 and the inside diameter hoop face interference fits of gland 3, and press close to graphite copper sheathing 5.The periphery of gland 3 is provided with flange circle, and flange circle is processed with flange hole, and bolt makes gland 3 and roller 2 be connected and fixed through flange hole.Roll shaft 1 is installed in the axis hole of graphite copper sheathing 5 and back-up ring 4, makes roll shaft 1 and graphite copper sheathing 5 and back-up ring 4 matched in clearance.Roll shaft 1 two ends are arranged on supporting plate, can use.After improving, before 140 punch machines, Centering Roll uses six months online, does not occur roller 2 stuck phenomenon, improves service life one times.
embodiment 2:as shown in Figure 2, during the Centering Roll adopting another Technical Design of the present utility model new, without gland 3, spacer ring 6 is lengthened, from the axis hole two ends of roller 2, spacer ring 6 interference fit is installed and fixes; The periphery of graphite copper sheathing 5 and back-up ring 4 and the recessed seam inside diameter hoop face interference fit of spacer ring 6, then roll shaft 1 is installed in the axis hole of graphite copper sheathing 5 and back-up ring 4, make roll shaft 1 and graphite copper sheathing 5 and back-up ring 4 matched in clearance, can use.
Graphite copper sheathing 5 described in the utility model is known public, can market purchasing or look for producer customized, repeats no more.
