Abstract
The utility model provides a wire-cutting electrode wire storage drum reversing control device. A cam connection rod mechanism is driven by forward rotation of a motor (1). The other end of a connection rod (3) of the cam connection rod mechanism is connected with a rack (7) which can be driven by the connection rod to do reciprocating movement periodically when a cam (2) of the cam connection rod mechanism rotates. A gear meshed with the rack is connected with an electrode wire storage drum (4) through a transmission mechanism (5). By means of the wire-cutting electrode wire storage drum reversing control device, a control circuit can be simplified, frequent braking, speed deceleration and stalling of the motor are avoided, the device failure rate is reduced, quick loss of electrode wires is reduced, the service life of the electrode wires is prolonged, and production efficiency can be improved.
Description
Technical field
The utility model relates to a kind of spark coil cutting processor bed, is a kind of line cutting wire storage cylinder control device for reversing of spark coil cutting processor bed specifically.
Background technology
The working method of the mechanical type wire storage cylinder control device for reversing of tradition Wire-cut Electrical Discharge Machining lathe is as follows: the wire electrode of the fast wire winding mechanism of spark coil cutting processor bed is entirely wound on wire storage cylinder with some tension, wire storage cylinder is connected with drive motors by yielding coupling, rotate, move vertically, wire travelling speed equals the linear velocity of wire storage cylinder periphery simultaneously.For reusing this segment electrode silk, need to pass through electrical control gear, control motor brake and slow down, stop, reversing, thereby control wire storage cylinder reversion, making becomes and receives silk end for silk end, and wire electrode oppositely moves, and so cycle alternation running, realizes and moving back and forth.
Existing problems: 1, commutate in order to control wire storage cylinder consecutive periods, need to control motor consecutive periods ground forward, brake deceleration, stall, reversion, brake deceleration, stall by electrical control gear, in deceleration, stalling, wire travelling speed alters a great deal, cause the quick loss of wire electrode, affected the service life of wire electrode.2,, under this electrical control working method, the braking of motor is very large to the influence of fluctuations of electric current with starting, to motor, control circuit, is all a kind of infringement, has improved equipment failure rate.3, during motor stalling, processing feed arrangement stops the feeding of cut direction, and electric discharge device stops electric discharge processing, thereby has affected production efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of in the situation that of the long-term normal forward of motor, can realize the forward and reverse of control wire storage cylinder, thereby realizes the reciprocating line cutting of wire electrode wire storage cylinder control device for reversing.
The line cutting wire storage cylinder control device for reversing that the utility model provides, cam link mechanism is driven by motor forward, can be by the reciprocating tooth bar of this connecting rod band action periodicity when the connecting rod other end of cam link mechanism is connected to a rotation of the cam at cam link mechanism, one is connected with wire storage cylinder by a transmission mechanism with tooth bar meshed gears.
This tooth bar is arranged on one on its reciprocating chute.
This transmission mechanism is belt gear or chain drive, or this transmission mechanism is for supplying gear and the coaxial mounted central shaft of wire storage cylinder.
The beneficial effects of the utility model:
Can simplified control circuit; in use; electric discharge device electric discharge does not need to suspend because of motor stalling; can realize processing feed arrangement cut direction continuous feed, avoid frequently braking deceleration, the stall operation of motor, more be conducive to the protection of motor and control loop; reduced equipment failure rate; reduced the quick loss of wire electrode simultaneously, extended the life-span of wire electrode, thereby can enhance productivity.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is the cooperation schematic diagram of rack and pinion part of the present utility model.
The specific embodiment
See figures.1.and.2, the line cutting wire storage cylinder control device for reversing that the utility model provides, cam link mechanism is driven by motor 1 forward, connecting rod 3 other ends of cam link mechanism are connected to when a cam 2 at cam link mechanism rotates can be with periodically reciprocating tooth bar 7 of action by this connecting rod 3, one is connected with wire storage cylinder 4 by a transmission mechanism 5 with tooth bar 7 meshed gears 8, this transmission mechanism 5 belt gear that large small belt pulley and belt form of serving as reasons, this tooth bar 7 is arranged on one on its reciprocating chute 6, above-mentioned all installation in same frame.
The utility model in use, motor 1 forward, by driving-belt driving cam 2 forwards, connecting rod 3 band carry-over bars 7 are done periodically to move back and forth on chute 6, tooth bar 7 rotates and reverse gear 8, then makes the wire storage cylinder 4 positive decommuntations in consecutive periods ground by transmission mechanism 5.
