Abstract
An apparatus of asynchronous electric discharge machine for wire cut adopted for use in machine industries employs a first electric discharge machine unit and a second electric discharge machine unit to provide electric energy to a cutting wire to generate alternate ignition and discharge on a work piece. The asynchronous operation uses two different discharge circuits in two different time sequences to reduce the probability of occurring discharge at the same spot and effectively reduce pause time, and prevent the cutting wire from rupturing, thereby to reduce production cost and improve operation efficiency.
Claims15
An apparatus of asynchronous electric discharge machine for wire cut for machining a work piece, comprising:
- a cutting wire;
- a first electric discharge machine unit including an upper machine guide connecting to one end of the cutting wire to generate an ignition discharge to perform cutting machine for the work piece;
- a second electric discharge machine unit including a lower machine guide connecting to another end of the cutting wire to generate another ignition discharge to perform cutting machine for the work piece;
- and
- an ignition power supply device connecting to the first electric discharge machine unit and the second electric discharge machine unit to provide energy required for generating ignition operation;
- wherein the first electric discharge machine unit and the second electric discharge machine unit alternately perform machine for the work piece to prevent the ignition discharge from occurring on a same spot of the work piece and resulting in rupturing of the cutting wire;
- wherein at least one of the first electric discharge machine unit and the second electric discharge machine unit further includes a first ignition module which has one end connecting to the ignition power supply device and another end connecting to the upper machine guide to generate an ignition.
A method of asynchronous electric discharge machine for wire cut accomplished through a cutting wire anchoring on an upper machine guide and a lower machine guide for machining work piece, comprising steps of:
- a. providing a first ignition energy to the upper machine guide;
- b. processing electric discharge cutting machine on the work piece through the upper machine guide and the cutting wire;
- c. suspending operations for a preset time period;
- d. providing a second ignition energy to the lower machine guide;
- e. providing both a DC power supply and a AC power supply;
- and
- f. processing electric discharge cutting machine on the work piece through the lower machine guide and the cutting wire;
- wherein the ignition power supply device is selected from the DC power supply or the AC power supply.
