Background technology
The mode of cutting of banding machine is " roller shear ", and is used for two dise knifes up and down of roller shear, the precision of nominal clearance when static state and the dynamic clearance when rolling, and whether directly have influence on the limit portion of strip after cutting jagged.The main means of adjusting play have two kinds, and the one, use many dise knifes, cushion rubber that thickness is different and Bao Huan constitute the distance and the gap of going up between lower round knife; The 2nd, between cutter and cutter shaft, expansion set is installed, as removable tool rest.The former needs the instrument of a lot of different sizes, and downtime is very long when operation inconvenience and transposing product specification; The latter operates simple and easy, but the accuracy rating of product is decided by the accent crack precision of expansion set.At present, the domestic expansion set that uses is the needle-type ringfeder of import and homemade bikini ringfeder.The former precision is very high, but costs an arm and a leg; Latter's price is low, but precision is also low.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of fluid pressure type dise knife holder is provided, and simple in structure, easy to operate, can guarantee higher accent crack precision, price is also lower.
In order to address the above problem, the invention provides following technical proposals: a kind of fluid pressure type dise knife holder, by expansion set, pressure plunger and forcing screw constitute, wherein,
Interior oil pocket is contained in described expansion set inside;
Described pressure plunger is paired Φ 16 plungers;
Described pressure plunger is pressed into interior oil pocket by oil duct with pressure oil;
Described forcing screw is paired M20 screw, axially links to each other with pressure plunger.
On the such scheme basis, consider uniform two one-way pressure valves on described expansion set cylindrical, this check valve is located on the repairing hole of leading to oil pocket.
The utility model is to utilize the fluid power amplification principle, by locking a pair of forcing screw, promotes a pair of pressure plunger, sets up oil pressure in interior oil pocket, thereby makes the thin-walled distortion in the cover, and himself is fixed on the cutter shaft.
Superiority of the present utility model is: simple in structure, easy to operate, guarantee higher accent crack precision, because of hydraulic locking power much larger than various mechanical type tool rests, so precision is reliable.It is much lower that price is compared the needle-type expansion set of equal accuracy.

The specific embodiment
Partly cut open shown in structural representation and Fig. 2 the utility model work schematic diagram as Fig. 1 the utility model, a kind of Fluid pressure type dise knife holder, be enclosed within axle and banding machine lower shaft on the banding machine respectively, be used for fixing dise knife 8, by expansion set 2, pressure plunger 3 and forcing screw 5 constitute, wherein,
Interior oil pocket 1 is contained in described expansion set 2 inside;
Described pressure plunger 3 is paired Φ 16 plungers;
Oil pocket 1 in described pressure plunger 3 is pressed into pressure oil by oil duct 4;
Described forcing screw 5 is paired M20 screw, axially links to each other with pressure plunger 3.
The utility model is to utilize the fluid power amplification principle, by locking a pair of forcing screw 5, promotes a pair of pressure plunger 3, oil pocket 1 in pressure plunger 3 is pressed into pressure oil by oil duct 4, thus the inside and outside wall of oil pocket 1 deforms in making.Because of the thickness of outer wall, just its rigidity is more much bigger than inwall, and last distortion all concentrates on expansion set 2 endoporus, thereby allows expansion set 2 endoporus embrace cutter shaft, reaches expansion set 2 located and transmitted moment of torsion on cutter shaft purpose.Certainly, as long as unclamp forcing screw 5, interior oil pocket 1 reinstatement, expansion set 2 endoporus unclamp cutter shaft, thereby expansion set 2 can be displaced to any new position, restart work.
Consider the needs of repairing, uniform two one-way pressure valves on described expansion set 1 cylindrical, this check valve is located on the repairing hole 7 of leading to oil pocket.Repairing hole 7 described in the present embodiment is the shoulder hole at aperture band M12 screw thread, is placed with φ 8mm steel ball 6 in the macropore, and aperture leads to oil pocket, and the aperture is pushed down steel ball 6 backs with M12 holding screw (not shown) and constituted one-way pressure valve.
When using the utility model, dise knife or glue ring are contained in earlier on expansion set 2 flanges, place again on the axle of whetting a knife, go up grinding machine then blade is ground, grind to the end face run-out tolerance below 8 μ.Before handle component is put on the cutter shaft again.Essential cleaning expansion set 2 endoporus and cutter shaft cylindrical earlier; As required, adjust the position of expansion set 2 on cutter shaft, and then the forcing screw on the locking expansion set 2.Each expansion set 2 has a pair of forcing screw 5.In case when needing to lock after the position of tool rest on cutter shaft determined, just rotate a forcing screw 5 earlier with 10 person of outstanding talent's meter T-wrenches; When hand feels stressed, just stop operating.This illustrates that this forcing screw 5 shifted pressure plunger 3 onto bottom, and oil pocket 1 inner wall deformation in perhaps having made has been embraced cutter shaft, but embraces power not enough.At this moment, will rotate cutter shaft gently, be in the position of conveniently tightening up to second forcing screw 5.But never to make expansion set 2 displacements this moment.After checking that once more blade position is errorless, just begin to tighten second forcing screw 5.Approximately with 10 newton's pretightning force, be the degree that the ordinary people tightens, behind the locking forcing screw 5, blade can carry out work.
In the time of need unloading expansion set 2, also to unclamp a forcing screw 5 earlier, fall back on recess, up to till near the pin on the recess.Unclamped as expansion set 2, then needn't unclamp second forcing screw 5.Still do not unclamp as expansion set, then unclamp second forcing screw 5.
In the long-term process of using, pressure oil can be separated out little air, and original pressure oil volume is reduced, and influence is used, and it is not enough to be embodied in the coupling mechanism force of expansion set 2 on cutter shaft, at this time needs to discharge air, supplementary pressure oil.Must be placed on expansion set 2 on cutter shaft or the sharpening axle during filling pressure oil, prevent inner wall deformation.Its method is: unclamp two holding screws earlier, take out the grease nipple of screwing on behind two φ 8mm steel balls 6, use common grease gun fatten from a repairing hole, till grease is emerged in another repairing hole.Stuffing finishes and puts two φ 8mm steel balls 6 again into, locks two holding screws and gets final product.Behind the pressure oil of annotating once or twice, the phenomenon that expanding cover locking power descends just is difficult for taking place again.
