The specific embodiment
The complex-curved disposal molding equipment of a kind of roll, comprise frame, motor, traffic cycle, blank workbench, cutter feeding device and servo-drive system.Described frame is provided with traffic cycle 3, and traffic cycle drives rotation by spindle motor 2 by gear train, for fixing and drive blank workbench 6 rotations.The rotating shaft 10 of two synchronous rotaries is installed, for secured blank on described blank workbench.Described cutter feeding device, comprise guide rail 9, slippage supporting plate 8, slippage supporting plate 7, knife bar 5.Supporting plate 7 is fixedly connected with knife bar 5, and its inside is provided with the power conveying mechanism in addition, and the power conveying mechanism is servomotor.Described slippage supporting plate 8 inside are provided with the power conveying mechanism, and the power conveying mechanism can be servomotor, cylinder or hydraulic cylinder etc.Described servo-drive system servo drive control spindle motor drives turntable rotation, controls the cutter feeding device servo feed, and controls rotating shaft rotation on the blank workbench.
Based on the said equipment, for thering is complex-curved roll, the invention discloses a kind of effective method for processing forming.As shown in Figure 2, its effective working portion is formed by a positive circular arc and two anti-circular arc smooth connections the cross sectional shape of roll, whole roll have ，Ge Duan cross section, 3 sections variform cross sections camber line to form and radius of curvature different.At first, the roll finished product of standard is surveyed and drawn, be take the roll geometric center as initial point, with certain angle [alpha], the standard roll is divided to n cross section as shown in Figure 3, and each cross section is got to the point of some, meter is calculated the coordinate of each point.For example as shown in Figure 4, get the i point, measure i point coordinates (x

set up fitting surface, form a some curved surface of (continuous also referred to as G0), i.e. C level curved surface continuously.Again C level curved surface is carried out to the differential processing, obtain point coordinates and obtain discrete data, discrete data is carried out to curved surface by least square method to it and approach matching, form the tangential curved surface of (continuous also referred to as G1), i.e. a B level curved surface continuously.Obtain again curved surface being divided and with differential form, its curved surface being carried out to the discretization processing by less angle after the B level curved surface of roll rolling workspace.By again discrete data importing computer data, finally by computer, the data of lane database are converted into to programmed instruction and transfer to control system.
The instruction of control system fetch program, the control appliance operation.Wherein traffic cycle drive blank workbench rotates around the y axle with a fixed angular speed.The cutting main motion of cross section circular curve profile is as shown in Figure 4 controlled in the rotation of traffic cycle, and its velocity of rotation has determined the cutting rate of cross section circular curve profile.Rotating two roll blanks of drive by rotating shaft rotates around the z axle with certain speed simultaneously in opposite directions.The forming and cutting campaign by the workpiece circular order profile shown in Fig. 3 dotted line is controlled in the rotation of rotating shaft, and its velocity of rotation has determined the speed of forming and cutting and the switching of the adjacent processing of workpiece cross section of workpiece circular order profile.Drive feed box by mounting plate and drive knife bar and cutter, make the enterprising assigned address that is given to of cutter x direction of principal axis cut out first paragraph circular arc R 1 as shown in Figure 4.After traffic cycle forwards respective angles to, feed box is done the feeding on x axle opposite direction with respect to mounting plate with certain speed.The cutting feed motion of the Y0 direction of the Feed Motion Control of feed box cross section curve profile as shown in Figure 4, its feed speed affects the radius of curvature size of second segment circular arc R 2 curves.Three-shaft linkage has formed the generate processing and forming to the three-dimension curved surface of two symmetrical roll blanks.
After by computer, data being transported to control system, the operation of control system control appliance forms the curved surface generate cutting to workpiece.The method of this generating motion can be that the double bracket plate motion addition method can be also single mount plate software control method.Wherein the double bracket plate motion addition method is as follows: after clamping workpiece, thereby the power conveying mechanism of control system drives bottom plate 8 to make the mounting plate 9 of connection on bottom plate 8 and the position of feed box arrival appointment make cutter arrive initial processing position.Control the drives spindle motor running by control system again and drive traffic cycle and rotate to drive the blank worktable rotary, thereby the pair cross-section formed the roll top pass curved surface of paired processing is cut.The rotating shaft of simultaneously controlling on the blank workbench turns round with certain speed, makes the roll top pass curved surface of paired processing can complete 360 degree ring cuttings.When rotating shaft drive changing of workpieces is crossed certain angle, the power conveying mechanism of control system drives mounting plate 9, thereby the cutter that makes to be fixed on feed box changes roll top pass curved surface master circular arc R 1 size shown in amount of feeding change Fig. 4.When forwarding control system in certain angle to, traffic cycle sends data signals to the servomotor of controlling feed box, make feed box 7 direction feeding along the track on mounting plate 9 with certain speed, thereby the reverse circular arc (R2 section circular arc as shown in Figure 4) be controlled to the roll top pass curved surface of processing generates.Now, the equipment three-shaft linkage has formed the generate processing and forming to the three-dimension curved surface of two symmetrical roll blanks.Single mount plate software implementation method is as follows: remove mounting plate 9, feed box 7 is connected with bottom plate, thereby control with software program the feed motion forward or backwards that the feed box servomotor is controlled feed box x direction, now, rotating shaft is rotated the roll top pass curved surface master circular arc R 1 bring and is changed and need the change of tool feeding amount and traffic cycle to forward the cutting of the anti-circular arc R 2 of roll top pass curved surface after certain angle to need the change of tool feeding amount all to be realized by the stack of feed box servomotor controlled motion.The superimposed motion obtained is superimposed around rotatablely moving of Y-axis with traffic cycle again, has formed the complex-curved stretching cutting processing of breaker roll groove.
Derivative embodiment:
As shown in Figure 5, set up coordinate system, this coordinate system X-axis, Y-axis are fixed, and the normal direction of blank worktable upper surface of take is Z-direction, and Z axis vertical Y axle also rotates around Y-axis.Wherein traffic cycle rotates around Y-axis, and rotating shaft drives workpiece and rotates around Z axis, and feed box 7, mounting plate 9 can be along the X-direction rectilinear motions, and bottom plate 8 moves up and down along Y-direction.
This example basic structure is identical with the basic example scheme, and different is this equipment to be made to vertical structure adopt 13 end face bearings, has reduced the rotating disk height, makes more compact structure, and clamping workpiece is more convenient, has reduced the task driven moment of traffic cycle.
