Abstract
The utility model discloses a hydraulic servo battery pole piece rolling mill which comprises a base, a rack installed on the base, two pair of bearing seats fixedly arranged on the rack, milling roller main bearings assembled on the bearing seats, two large axial diameters respectively used for rolling upper and lower rollers and assembled in a milling roller bearing, a hydraulic system matched with the rolling mill and controlled by a computer, clearance adjusting bearings sleeved on two small axial diameters respectively used for rolling the upper and the lower rollers and installed in clearance adjusting bearing seats, and servo hydraulic cylinders used for rolling the upper and the lower rollers and providing vertical moving force and installed on the upper and the lower clearance adjusting bearing seats. After the structure is adopted, the hydraulic cylinders can be adjusted on line through the servo control valve controlled via the computer, and the purpose that the deflection deformation and the milling roller bearing clearance during the process of rolling the battery pole pieces through the milling rollers can be adjusted on line and at random can be achieved through applying certain pressure to the small axial diameters of the milling rollers.
Description
Technical field
The utility model relates to a kind of milling train of rolling battery pole piece, refers in particular to a kind of milling train by hydraulic way control battery pole piece precision.
Background technology
Battery pole piece is one of critical piece of battery, and the pole piece of its same thickness requires have the homogeneous thickness deviation, also requires even transition when connecting and make the pole piece of same thickness keep homogeneous thickness between the pole piece of different-thickness.Therefore require the rolling just relatively stricter of cell thickness, its milling train permissible accuracy is also than higher.
Milling train in the operation of rolling, the easy stressed generation deflection deformation of upper and lower roll, and again because there is the gap in the bearing of rolling mill roll, the thickness of rolling base material also thin and thick differs, thus influenced the precision of rolling pole piece.
The mode of regulating roll seam and deflection deformation now belongs to off-line and adjusts mode; promptly when adjusting gap between the upper and lower roll and deflection deformation, need shut down then and adjust; after finishing, adjustment is rolled the work of pole piece again; can't realize online adjusting; this has not only influenced the precision of rolling pole piece, has also influenced production efficiency.
The utility model content
The utility model technical issues that need to address provide a kind of milling train of controlling roll bending distortion and roll bearing gap by hydraulic way automatically.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of hydraulic servo battery pole piece rolling mill, comprise base, be installed in the frame on the base, installing two pairs of bearing blocks on the frame, on the bearing block respectively frame adorning the roll base bearing, in the roll bearing respectively frame adorning the large-diameter that rolls top roll and the large-diameter that rolls lower roll, with the supporting computer-controlled hydraulic system of milling train, at the small axle diameter that rolls top roll with roll on the small axle diameter of lower roll suit and accent crack bearing, transfer the crack bearing to be installed in and transfer in the bearing block of crack, last, install on the downward modulation crack bearing block promising roll top roll and roll lower roll the servo hydraulic cylinder that moves up and down strength is provided.
Further improvement of the utility model is: the base of servo hydraulic cylinder is installed on the bearing block of downward modulation crack, and the free end of hydraulic mandril is installed in and raises on the bearing block of crack.
Further concrete structure of the present utility model is: hydraulic system comprises the pilot valve that is connected between constant pressure oil source, hydraulic cylinder, constant pressure oil source and the hydraulic cylinder; Be provided with the pressure sensor of induction cylinder pressure between hydraulic cylinder and pilot valve in the fluid pressure line, pressure sensor is connected with computer.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
In the operation of rolling, because rolling base material uneven distribution is even, this can cause that roll produces different deflection deformation or roll bearing gaps and changes at random.After adopting the utility model, can pass through by the online regulator solution cylinder pressure of computer-controlled pilot valve, small axle diameter by breaker roll applies certain pressure, thereby reaches online deflection deformation and the roll bearing gap of roll when rolling battery pole piece of regulating at random.
Hydrauservo System is compared with the system of other type, has following advantage: the power-weight ratio and the moment-ratio of inertias of Hydraulic Elements are big, and the moment of transmission and power are very big.Therefore can form that volume is little, in light weight, acceleration capacity is strong and QA servo-drive system, control high-power and big load.The hydraulic actuator response speed is fast, and hydraulic actuating mechanism stable drive, antijamming capability are strong, and speed adjustable range is wide, the control favorable working performance under the special low cruise state.
