Abstract
The invention relates to a numerical control medium-speed wire cut electrical discharge machine, which can effectively ensure machining stability and machining dimension accuracy and reduce the running cost. The numerical control medium-speed wire cut electrical discharge machine comprises a wire cut electrical discharge machine. Closed loop control is performed on a wire feeding wheel and a wire winding wheel in a wire feeding mechanism in the wire cut electrical discharge machine by a servo motor; a constant tension controller detects the tension of a wire electrode and controls the reversal of the wire feeding wheel and the wire winding wheel; the wire feeding wheel and the wire winding wheel form a U-shaped wire electrode tension traveling track by bottom guide wheels and a winding guide wheel; and a jewel positioner is positioned between the bottom guide wheel and the winding guide wheel at intervals. The machine has the advantages that: 1, the advantages of a step drive high-speed wire cut electrical discharge machine and a step drive low-speed wire cut electrical discharge machine are creatively designed, while the shortcomings of the step drive high-speed wire cut electrical discharge machine and the step drive low-speed wire cut electrical discharge machine are abandoned so as to realize the stable machining of machined work pieces and achieve high machining accuracy and low running cost; and 2, the jewel positioner effectively controls the running stability of molybdenum wires, and greatly improves the machining accuracy.
Description
Technical field
The present invention relates to a kind ofly can either guarantee the stability of processing and the precision of processing dimension effectively, can reduce widely again in a kind of numerical control of operating cost and walk wire cutting machine, belong to walking wire cutting machine and make the field.
Background technology
The wire cutting machine tool of Xiao Shouing in the market, its wire feeder has two kinds of modes on structural design: the one, the fast wire of stepper drive, the 2nd, a lathe of being careful.Its weak point: though the fast wire machine tool of the stepper drive in this dual mode price is low, operating cost is low, processing is unstable, the low precision of processing dimension; Though and a lathe price height of being careful, processing is stable, dimensional accuracy is high, the operating cost height.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design and a kind ofly can either guarantee the stability of processing and the precision of processing dimension effectively, can reduce widely again in a kind of numerical control of operating cost and walk wire cutting machine.
Design: in order to realize above-mentioned purpose of design.The application gets the length of the fast wire of stepper drive and a lathe of being careful on the basis of background technology, remove its weak point and design.1, adopts two-way long-time wire feeder, it supplies silk and receives independent silk and the receipts silk of supplying of silk difference, the purpose of doing like this is: owing to adopt the servomotor closed-loop control independently for silk and receipts silk respectively for silk and receipts silk, and closed loop servo control is made up of servomotor, alternative route, servo amplifying circuit, speed detector and the position detector that is installed on the workbench, workbench actual displacement amount is detected automatically in this control and the and instruction value compares, control with difference, so the positioning accuracy height; Secondly, closed loop servo control is examined the tension data that does not have according to constant tension controller, can control the tension force for wire electrode between silk wheel and the wire drawing wheel effectively, both can effectively solve the machine tooling dimensional accuracy of products, and operating cost is reduced widely; The 3rd,, under the effect of commutator, can exchange mutually for silk wheel and wire drawing wheel, promptly also can become wire drawing wheel, wire drawing wheel and also can become for silk and take turns for the silk wheel.2, wire electrode adopts jewel locator location, is two of technical characterictic of the present invention.The purpose of doing like this is: installing electrodes silk locator on wire cutting machine, and it not only can reduce the vibration of wire electrode effectively, the stability of effective control electrode silk operation, and can reduce machined surface roughness, and improve machining accuracy, boost productivity.3, adopting the design of constant tension controller detecting electrode thread tension, is three of technical characterictic of the present invention.The purpose of doing like this is: because constant tension controller can either be gathered the signal that tension pick-up feeds back, can handle the signal of being gathered again, and can also send instruction to execution unit according to these signals, reach the purpose of adjusting execution unit output, changing tension force.
Technical scheme: walk wire cutting machine in a kind of numerical control, it comprises the cabling wire cutting machine, describedly walk in the wire cutting machine adopting the servomotor closed-loop control respectively and take turns for silk and the commutation of wire drawing wheel in the wire feeder by constant tension controller detecting electrode thread tension, control for silk wheel and wire drawing wheel, for constituting U font wire electrode tension run trace by end directive wheel, receipts silk directive wheel between silk wheel and wire drawing wheel, jewel locator spacing is positioned at end directive wheel and receives between the silk directive wheel.
The present invention compares with background technology, the one, the fast wire lathe of stepper drive and the machine advantage separately of being careful have been carried out creationary design, escape to eliminate the shortcoming that it exists separately, not only realized stable processing, and machining accuracy height, operation cost are low workpiece to be machined; The 2nd, the stability that molybdenum filament moves is effectively controlled in the employing of jewel locator, has greatly improved machining accuracy.
