Abstract
The invention discloses a method for controlling a cycloid motor in the coiling device of multi-line cutter, while steel wire is uniformly distributed on the coiling wheel. the invention is characterized in that when the coiling wheel coils wire to two ends and steers section, in each cutting period, the cycloid motor drives block straightly with reduced displacement and increased end stop time, until the coiled wire reaches end, and the cycloid motor steers coiling direction. The invention can uniformly distribute the steel wire on the coiling wheel, to reduce more than 80% of broken wires, with high stability and the replacement on servo motor.
Description
Technical field:
The present invention relates to a kind of multi-line cutting machine, the control method of cycloidal generator in specifically a kind of multi-wire saw take-up unit.
Background technology:
When utilizing the multi-line cutting machine cut workpiece, because the steel wire institute's high speed reciprocation cycle of doing motion in the cutting process, steel wire is evenly closely arranged particularly important on take-up pulley.When cycloidal generator in the take-up adopts ordinary gear deceleration buncher, because of its braking and instantaneous reverse poor-performing, so can cause on the take-up pulley wire to be spindle arranges, under this situation, linear velocity unanimity and tension dynamic balance require and the footpath short time variation in a big way of take-up pulley line makes take-up servomotor rotating speed that adjustment by a relatively large margin must be arranged, so, in line cutting machine runs up cutting, very easily cause broken string, use to line cutting machine and bring unnecessary loss.As adopt servomotor to control take-up side-sway line, then cost height.
Summary of the invention:
It is low to the purpose of this invention is to provide a kind of use cost, the control method of cycloidal generator in the multi-wire saw take-up unit that steel wire is evenly closely arranged on take-up pulley.
The present invention adopts following technical scheme to realize its goal of the invention, the control method of cycloidal generator in a kind of multi-wire saw take-up unit, when take-up pulley take-up to end positions commutates section, cut in the cycle each time, cycloidal generator drives the displacement of pulley rectilinear motion and successively decreases one by one, the end position time of staying increases progressively one by one, directly causes take-up and approaches the end position, the commutation of cycloidal generator take-up direction.
The present invention controls cycloidal generator and drives pulley rectilinear motion take-up displacement from holding the position less than 3-5mm
The time, the commutation of cycloidal generator take-up direction.
Owing to adopt technique scheme, the present invention has realized goal of the invention preferably, arrange evenly through using the take-up pulley steel wire, cause broken string to reduce more than 90% because of take-up is uneven, and it is very easy to adjust maintenance, improved the machine reliability, can replace the effect of servomotor fully, had high performance price ratio in same position.
Description of drawings:
Fig. 1 is the time-displacement diagram that is connected pulley in the prior art with cycloidal generator;
Fig. 2 is a prior art take-up pulley take-state schematic diagram;
Fig. 3 is time-displacement diagram that cycloidal generator of the present invention connects pulley;
Fig. 4 is a take-up pulley take-state schematic diagram of the present invention.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing.
As seen from Figure 1, Figure 2, the prior art cycloidal generator adopts ordinary gear deceleration buncher, with servomotor relatively, have with low cost, easy to maintenance, advantage such as control is reliable convenient.But its braking and instantaneous reverse poor-performing are arranged so can cause on the take-up pulley wire to be spindle.
As shown in Figure 3, the control method of cycloidal generator in a kind of multi-wire saw take-up unit, when take-up pulley take-up to end positions commutates section, cut in the cycle each time, cycloidal generator drives the displacement of pulley rectilinear motion and successively decreases one by one, the end position time of staying increases progressively one by one, directly causes take-up and approaches the end position, the commutation of cycloidal generator take-up direction.The present invention controls cycloidal generator and drives pulley rectilinear motion take-up displacement when holding the position less than 3-5mm (present embodiment is 3mm), the commutation of cycloidal generator take-up direction.Pulley of the present invention moves forward and backward by the operation particular requirement, and steel wire is evenly closely arranged on take-up pulley (as shown in Figure 4).
Claims (2)
