Abstract
The utility model discloses a new saw cover, which is suitable for sawing machines that are used for cutting and processing materials. The lateral stiffness of a saw blade is effectively improved by a vibration damper, a hydrodynamic pressure, and a lubricating film, wherein, the vibration damper is arranged on the cover casing of the saw blade, and the hydrodynamic pressure and the lubricating film are formed by the elastic blocks of the vibration damper and the surface of the saw blade; the transversal amplitude of the saw blade is decreased; noises which are produced by the saw blade are obviously reduced. The utility model is suitable for various disc sawing machines; particularly the disc sawing machines for hot-cutting metal.
Description
The utility model belongs to material and cuts off the saw cover that the process equipment territory is specifically related to sawing machine.
Cut off in the processing industry at material, saw blade all can produce oscillation crosswise and very big noise when garden disc type sawing machine sawing metal and nonmetallic materials.In order to address this problem.R.W.LLIS and C.D.MOTE, JR.(ASME, Journal of Dynamic Systems, Measuremsnts, and Control, VOL 101, and MARCH1979 PP44-49) has manufactured experimently a kind of vibrational feedback controller, the variation that it adopts vibrating sensor to record the saw blade amplitude signal, be arranged symmetrically in the active force of saw blade both sides electromagnet to saw blade by the feedback control system change then, reaching increases saw blade lateral stiffness and vibration damping, reduces the effect of saw blade oscillation crosswise.Yet the electromagnet of this feedback controller can magnetize saw blade, and saw blade absorption irony powder influences sawing normally to carry out, thus it should not be applicable to the sawing ferrous metal time to the control of saw blade.This feedback control system link is more in addition, and structure is complicated.
The utility model purpose provides a kind of lateral stiffness that can not only improve saw blade effectively, reduces the saw blade lateral amplitude of vibration, and can reduce the noise that saw blade produces, and is applicable to the Saw cover of various gardens disc type sawing machine.
On the case of saw blade, vibration damper is installed, the elastomer block (9) of this damper is arranged symmetrically in the saw blade both sides and presses close to saw blade (3), interstice coverage between elastomer block (9) and the saw blade (3) is at 0.02～0.2mm, elastomer block (9) surface that contacts with saw blade (3) is the stairstepping plane, and ladder height is 0.01～0.1mm.During saw blade (3) high speed rotating, form hydrodynamic pressure and lubricating film between elastomer block (9) and saw blade (3) surface, thereby improved the lateral stiffness and the vibration damping of saw blade, reduced the lateral amplitude of vibration of saw blade, reduced the noise that saw blade produces simultaneously.
The utility model is owing to arranged that in the saw blade bilateral symmetry elastomer block (9) has increased the lateral stiffness of saw blade (3), saw blade thickness can reduce 5～15%, can reach the saving sawn timber, reduce the effect of sawing force and sawing energy consumption, increased the saw blade vibration damping simultaneously, adopt diameter phi 500～1800mm, thickness is that the saw blade of 2.0～10.0mm is tested, and the saw blade rotating speed is between 500～1800 rev/mins.Press the method and the step of GB4215-84 regulation, adopt engineering method, measure respectively have, the idle operator lamp of sawing machine during the undamped device, the result shows that deoscillator can reduce by 5～10 decibels of noises (A).Saw blade (3) surface forms hydrodynamic pressure with elasticity (9) surface, the size of this pressure increases with the gap between saw blade (3) and the elasticity (9) and reduces or to reduce and increase with the gap, has realized the FEEDBACK CONTROL of saw blade oscillation crosswise so simply and effectively.
Fig. 1 is the front view of the utility model Saw cover.
Fig. 2 is the side view of the utility model Saw cover.
It is as follows to provide embodiment in conjunction with Fig. 1 and Fig. 2:
This device is formed with bolt (10) connection by left case (1) and right case (2).Left side cover is fixed on the base, and right case is a movable guard so that change saw blade (3).Saw blade (3) is fixed on the turning cylinder (5) by left and right sides chuck (4).The vibration damper of two groups of symmetric arrangement is housed on the case of the left and right sides, and each damper all is made up of damping wedge (7), elastomer block (9), adjustment bolt (8), fastening bolt (6), inlet tube (11) and outlet (12).Elastomer block (9) is fixed on the damping seat (7) with fastening bolt (6), so that change elastomer block (9), damping seat (7) is installed in the hole of case.When crack between saw blade (3) and the elastomer block (9) surpasses allowed band, can utilize adjustment bolt (8) and fastening bolt (6) to regulate.The surface that contacts between elastomer block (9) and the saw blade (3) is the ladder plane, and the height of ladder is 0.01～0.1mm, and has splitter box (13) and backflash (14) on this plane.Inlet tube (11) is transported to the liquid of certain pressure between saw blade (3) and the elastomer block (9) to form dynamic pressure and lubricating film through splitter box (13).Thereby increased the lateral stiffness and the vibration damping of saw blade, reduced the amplitude and the noise of saw blade, mobile lubricating film can reduce the friction between saw blade (3) and the elastomer block (9), can cooling effect be arranged to saw blade again.Outlet (12) passes through backflash (14) with liquids recovery.
Claims (3)
1, a kind of sawing machine saw cover, comprise case, saw blade (3), chuck (4) and power transmission shaft (5), it is characterized in that being equipped with on left and right sides case (1) (2) vibration damper of two groups of symmetric arrangement, this damper is made up of damping seat (7), elastomer block (9), adjustment bolt (8), fastening bolt (6), population pipe (11) and outlet (12).
2, be fixed on the damping seat (7) with fastening bolt (6) according to the damper in the described saw cover of claim 1, elastomer block (9), damping seat (7) is installed in the hole of case.
3, this contacts the surface and is the ladder plane according to the damper of the described saw cover of claim 1, elastomer block (9) and saw blade (3), and it highly is 0.01～0.1mm, and has splitter box (13) and backflash (14) on this plane.
