Accompanying drawing explanation
Accompanying drawing 1 is the utility model syndeton schematic diagram;
Accompanying drawing 2 is the cross-sectional view of upper guide in the utility model.
The specific embodiment
For the ease of those skilled in the art's understanding, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in accompanying drawing 1,2, a kind of line cutting automatic wire feed device, includes a wheels 16, and stringing device, device for fusing, upper guide 9 and lower guider 91; Stringing device comprises wire leading pipe 5 and linear cylinder 6, and wire leading pipe 5 is by contiguous block and 6 attachings of linear cylinder, and linear cylinder 6 two ends are all provided with positive stop 4, and wire leading pipe 5 tops are provided with wire feed pinch roller 3, and wire leading pipe 5 belows are provided with contact roller 8; Device for fusing is located at wire leading pipe 5 belows, and this device for fusing comprises fusing electricity-supplying piece 7 and driver, and fusing electricity-supplying piece 7 is connected with actuator electrical; Upper guide 9 and lower guider 91 are contained in fusing electricity-supplying piece below from top to bottom successively.Enter a wheels 16 and comprise a plurality of rollers, for carry electrode silk, this is conventional means, and in this not go into detail.Fusing electricity-supplying piece 7 arranges two conventionally, and is setting up and down, and the distance between two fusing electricity-supplying pieces is relatively near, can relatively move.The switch of linear cylinder is housed, the action of control cylinder on positive stop 4.Linear cylinder drive is led wire leading pipe and is slided up and down.Wire feed pinch roller place is also provided with pressure sensor, facilitates the pressure on detection senses wire electrode.
Described upper guide 9 comprises body, in this body, is provided with and wears a passage 17, is provided with mobile electricity-supplying piece 11 in body, is provided with and is positioned at the cone tank 14 of wearing a passage in body, and body top is provided with coolant intake 15.Wire electrode is out entered afterwards and is worn a passage through this upper guide by wire leading pipe 5.On body, be provided with water under high pressure inlet opening 13, this high-pressure water inlet hole 13 is by being located at intrinsic water under high pressure intake tunnel 18 and wearing a passage 17 and be communicated with, water under high pressure is limited in wire electrode within the scope of water column, improves and wears an accuracy rate, is convenient to wire electrode and enters in lower guider.The structure of lower guider is consistent with the structure of upper guide, at this, is no longer repeated in this description.In body, be also provided with sealing ring 12.Mobile electricity-supplying piece 11 is connected with the extraneous cylinder that drives, and realizes the movement to certain distance space.
When the utility model is worn silk beginning, fusing electricity-supplying piece moves out, and makes can not touch electricity-supplying piece from wire leading pipe wire electrode out.Wire electrode is interted in entering a wheels, make this wire electrode along entering a wheels transmission.Wire electrode enters into wire leading pipe by wire feed pinch roller, and along with the rotation of wire feed pinch roller, wire electrode is down driven, and because wire electrode enters into wire leading pipe, so is effectively limited during wire electrode motion, can not depart from, and improves and wears an accuracy rate.Wire electrode is through wire leading pipe and toward downward-extension.Put on silk good, fusing electricity-supplying piece moves to wire leading pipe below contact electrode silk, connects processing power source.Then start the wire electrode that fuses, when fusing starts, the contact roller 8 of wire leading pipe below and the wire feed pinch roller 3 of top be all near wire electrode, by wire electrode compression, with the wire feed pinch roller 3 of upper back, reverses and provide tension force to the wire electrode between upper lower whorl.Fusing electricity-supplying piece 7, near wire electrode, is connected fusing power supply.When a bit of wire electrode between fusing electricity-supplying piece 7 is fused, the long segment electrode silk in top can not fuse, and can be because the effect heat temperature raising of electric current, after ring current cuts off, wire electrode is cooling in air-flow, reach the object of annealing, complete the heat treatment to wire electrode, make more directly stiffened more of wire electrode.
By fusing electricity-supplying piece, wire electrode is fused, wire electrode breakpoint melts under hot conditions, and under tension force effect, fracture becomes taper, and end diameter diminishes, and is beneficial to and wears silk.Wire electrode is after Overheating Treatment, and linear cylinder drives wire leading pipe 5 to move down, and when the contiguous block of linear cylinder 6 and wire leading pipe 5 is encountered the positive stop 4 of linear cylinder bottom, touches switching cylinder, cylinder stop motion.Now wire leading pipe 5 under lead mouth and just in time stretch into upper guide 9 tops, wire electrode is limited in wire leading pipe while moving in wire leading pipe 5, can not depart from, the degree of accuracy is high, so just can make wholely to wear silk action and link up.Wire electrode enters in upper guide, and the mobile electricity-supplying piece 11 in upper guide is first removed, and makes wire electrode smoothly through upper guide, inserts the wearing in a passage of upper guide.Rotary action along with wire feed pinch roller, and under the impact forces of the water under high pressure in upper guide, wire electrode moves along the cone tank in upper guide, and finally through workpiece, be drawn out, upper guide move forward into electric block reset, the beginning following process that switches on power, so far a whole process of wearing finishes.
Those skilled in the art should know; the above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
