Description
Technical Field
The utility model relates to a part of double-end spark-erosion wire cutting machine bed especially relates to a underarm subassembly of double-end structure.
Background
Electric discharge machining is machining by removing a workpiece by pulse discharge, and since a liquid dielectric does not contact the workpiece with a machining electrode, a hard and brittle conductor such as a metal or semiconductor material can be machined with a relatively soft electrode (tool). The cutting process with moving electrode wires is the most widespread in the electric discharge machining. The electrode wire cutting has two types of one-way wire (slow wire) and reciprocating wire (fast wire), wherein the reciprocating wire cutting is a self-developed electromechanical integration technology with complete intellectual property rights in China, is peculiar to China, and has the advantages of low equipment cost and repeated discharge use of the molybdenum alloy electrode wire (molybdenum wire). The method is particularly suitable for processing high-hardness, high-strength, high-melting point, high-toughness and high-brittleness materials (such as tungsten-molybdenum alloy, memory alloy, magnesium alloy, hard alloy, polycrystalline diamond, neodymium iron boron and the like) which are difficult to be processed by machinery, and is widely applied to processing and manufacturing of precise or special-shaped parts in various fields of die manufacturing, aerospace, medical instruments, instruments and meters, electronic and electrical appliances, mechanical manufacturing and the like.
At present, electrode wires (generally copper wires) cut by unidirectional wire feeding (slow wire feeding) wires are used in a one-pass mode, the electrode wires are led to a processing area from a wire storage cylinder, discharged once and then discarded after leaving the processing area, and particularly the electrode wires are seriously wasted during small-energy cutting; the electrode wire for the reciprocating wire-moving (fast wire-moving) wire cutting is repeatedly used for many times, but the electrode wire is subjected to discharge cutting in two directions of the reciprocating wire-moving, the length of the electrode wire is limited by a single wire cylinder structure (generally only 200-300 meters), the electrode wire is reversed for about 20 seconds to form frequent reversing stripes, and the processing precision is far inferior to that of the unidirectional wire-moving wire cutting.
For a double-head wire-cut electric discharge machine, a discharge pulse is sent to a discharge gap and innovative technological process control is implemented on the machine through an innovative double-frequency pulse power supply, so that the wire-cut electric discharge machine capable of simultaneously cutting and processing two workpieces by a double-head tool electrode can realize the unidirectional cutting of a filament (such as 10km), can eliminate the reversing stripes of reciprocating wire (fast wire) moving wire cutting, improves the processing precision of wire cutting, further can realize the effect of simultaneously cutting the two workpieces, and implements cutting processing when the electrode moves in any direction, thereby improving the working hour efficiency; the electrode wire is recycled, so that the electrode wire resource is saved compared with the electrode wire which is cut by a unidirectional wire (slow wire).
