Abstract

The utility model relates to an electric spark wire cutting machine tool, comprising a base; a wire runner which is composed of a pillar, an on-and-off wire arm with a guide wheel and a wire canister; a workbench and an electrode wire. The pillar, workbench, and wire canister are installed on the base. The on-and-off wire arm is fixed on the pillar. The workbench is composed of a mopping board in X direction, a mopping board in Y direction and a work support. The mopping board in X direction directly slides on the base. The mopping board in Y direction slides on the mopping board in X direction. The work support is installed on the mopping board in Y direction. The shape like the Chinese character 'hui' in the middle of the pillar. The electrode wire passes through the intermediate through hole in the 'hui' shape. The advantages of the electric spark wire cutting machine tool are that because a symmetrical structure of 'hui'-shaped pillar is adopted, the electric spark wire cutting machine tool assures the rigidity of the pillar and thus ensures the rigidity of entire machine. When installing the electrode wire, the electrode wire is carried by a wire-carrying carrier, which reduces labor intensity of wire-feeding and boosts work efficiency.

Technical field

The utility model relates to the electric spark linear cutting machine of a kind of electric spark linear cutting machine, particularly a kind of quick wire.

Background technology

The wire electrode of existing quick wire electrical discharge machine tool is got back to the silk tube from the silk tube to the workspace or from the workspace all need pass through column, the mode of passing column by wire electrode can be divided into two kinds: a kind of side from column is passed through, as in the quick wire electrical discharge machine tool of simple type, adopt wire electrode to pass through from the side of column, the column of such lathe is less, upper and lower silk arm sling arm is elongated, has a strong impact on the rigidity of lathe.The side of another kind of broken column and mistake, wire electrical discharge machine tool is like this mostly fast, its structure is general as Fig. 1, shown in Figure 2, it comprises base 1, by column 4, on the band guide wheel 10, following silk arm 6,7, the fortune guide frame that silk tube 5 is formed, workbench, wire electrode 8, described column 4, workbench, silk tube 5 is installed on the base 1, on, following silk arm 6,7 are fixed on the column 4, workbench 1 by X to planker 3, Y is to planker 2, work support 9 is formed, Y is to directly operation on base 1 of planker 2, X moves on planker 2 at Y to 3 of plankers, and work support 9 is installed in X on planker 3.Though such lathe has improved the elongated problem of upper and lower silk arm 6,7 cantilevers, increased the rigidity of lathe to a certain extent, the asymmetry of its column 4 is seen Fig. 3, Fig. 4, has influenced its rigidity, has also influenced the rigidity of complete machine.Simultaneously, such lathe needs when wearing thread all to adopt manually, has increased labour intensity, has reduced operating efficiency.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of electric spark linear cutting machine is provided, and to improve the rigidity of electric spark linear cutting machine, reduces the labour intensity when wearing wire electrode simultaneously, raises the efficiency.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of electric spark linear cutting machine comprises base, the upper and lower silk arm by column, band guide wheel, silk tin fortune guide frame, workbench, the wire electrode formed, and described column, workbench, silk tube are installed on the base, and upper and lower silk arm is fixed on the column; Described workbench is made up of to planker, work support to planker, Y X, and X directly slides on base to planker, and Y then slides on planker at X to planker, and work support is installed in Y on planker; Described column middle opening becomes " returning " shape, wire electrode to pass and " returns " intermediate throughholes of shape.

Increase guide wire apparatus in the above-mentioned electric spark linear cutting machine, guide wire apparatus is made up of the silk dolly that carries in motor, guide rail, belt driver, band mantle fiber hole, the silk dolly that carries of charged polar filament retaining mechanism is formed, carrying the silk dolly simultaneously is installed on the belt driver, another side is enclosed within on the guide rail, belt driver is by motor-driven, and whole guide wire apparatus is installed on column or the silk arm.By the driving of motor to belt driver, drive by belt driver again and carry the silk dolly, can realize carrying the silk dolly and on guide rail, backhaul row, promptly wire electrode can arrive another place from one along the guide rail direction automatically by carrying the guiding of silk dolly.

Above-mentioned guide wire apparatus has two up and down, can realize that wire electrode is connected to the silk process that goes up of another tube from a tube.

Compared with prior art, advantage of the present utility model is: because electric spark linear cutting machine adopts " returning " shape column of symmetrical configuration, guaranteed the rigidity of column, thereby guaranteed the rigidity of complete machine.When powering on polar filament, transport wire electrode, reduced the labour intensity of last silk, improved operating efficiency with carrying the silk dolly.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 5, shown in Figure 6, electric spark linear cutting machine, it comprises base 11, the upper and lower silk arm 16,17 by column 14, band guide wheel 11, the silk tube 15 fortune guide frames of forming, workbench, wire electrode 18, described column 14, workbench, silk tube 5 are installed on the base 11, upper and lower silk arm 16,17 is fixed on the column 14, workbench 11 is made up of to planker 12, work support 19 to planker 13, Y X, Y is to directly operation on base 11 of planker 12, X moves on planker 12 at Y to 13 of plankers, and work support 19 is installed in Y on planker 12.All there is wire electrode both sides, front and back by column 4, when wire electrode is got back to the silk tube through column 14 from the silk tube to the workspace or from the workspace, opening 141 are arranged in the middle of the described column, become " returning " shape, and wire electrode 18 passes back-shaped intermediate throughholes, sees Fig. 7, Fig. 8.
