Linear cutting machine with steam dispersion prevention protective cover

Technical Field

The utility model belongs to the technical field of the technique of wire cut electrical discharge machining bed and specifically relates to a wire cut electrical discharge machining bed with prevent steam dispersion protection casing is related to.

Background

The basic working principle of the wire cut electric discharge machine is that a workpiece is subjected to pulse spark discharge to remove metal by using a continuously moving electrode wire, so that the aim of cutting and forming is fulfilled. When the distance between the workpiece and the electrode wire is small enough, spark discharge is generated between the workpiece and the electrode wire, and an instantaneous high-temperature heat source is formed in an electrode gap to melt and gasify local metal. The special wire cutting working fluid is used for removing the scraps generated in the machining process. The vaporized working fluid and the steam of the workpiece material expand instantaneously, and the melted and vaporized workpiece material is thrown out of the discharge channel under the combined action of the thermal expansion and the stamping of the working fluid. In this process, part of the working fluid and the metal chips may be splashed onto the ground around the machine tool, contaminating the ground, resulting in deterioration of the working environment of the operating worker. In order to solve the above problems, a protective cover is usually disposed on the working table to prevent the working fluid and the metal chips from splashing.

The implementation principle of the embodiment is as follows:

after a worker installs a workpiece to be cut on the worktable surface 21, since the height of the blocking cover 4 is lower than that of the fixing plate 51, the suction cover 52 does not interfere with the blocking cover 4 in the process of placing the blocking cover 4 into the collecting tank 24, which is convenient for the worker to operate. When the linear cutting machine starts to cut and process the workpiece, the working fluid is sprayed on the workpiece and the electrode wire. The splashed working fluid is blocked by the barrier cover 4, and the working fluid in contact with the high-temperature workpiece is vaporized into steam. When the air extraction equipment works, the suction hood 52 generates suction force, and because the suction hood 52 is positioned above the workpiece and the suction hood 52 is aligned with the collection tank 24, the generated steam is all sucked away by the suction hood 52, so that the possibility of dispersion of the steam in a workshop is greatly reduced, the humidity of the air in the workshop is reduced, and other equipment in the workshop is effectively protected;

when the lower supporting plate 23 and the middle supporting plate 22 drive the workpiece to move, the suction hood 52 and the first connecting pipe 53 synchronously move along with the collecting tank 24, the corrugated pipe 6 is telescopically deformed along with the movement of the suction hood 52, and two ends of the corrugated pipe 6 are always kept to be communicated with the first connecting pipe 53 and the second connecting pipe 71. Before the steam enters the rotary pipe 72, condensed water formed by the condensation of the steam flows into the collection tank 24 along the suction hood 52. The steam entering the rotary pipe 72 condenses inside the rotary pipe 72, thereby reducing the steam entering the third connecting pipe 73. After the steam entering the third connecting pipe 73 is condensed in the third connecting pipe 73, the condensed water in the third connecting pipe 73 flows into the rotary pipe 72 along the third connecting pipe 73 which is obliquely arranged. The condensed water in the rotary pipe 72 is gathered at the bottom of the rotary pipe 72 under the action of gravity, flows into the drain pipe 74 under the action of gravity, and flows into the water receiving barrel 75 along the drain pipe 74;

when the time of use of the wire cut electrical discharge machine is short, the amount of condensed water flowing into the drain pipe 74 is small, and a water column having a sealing function to prevent air from entering the rotary pipe 72 from the end of the drain pipe 74 cannot be formed in the trap 743 of the drain pipe 74, and at this time, the opening at the lower end of the drain pipe 74 needs to be closed by the sealing plug 742. When the amount of water stored in the trapway 743 is sufficient, a worker can see through the sight glass 741, pull out the sealing plug 742, and the drain pipe 74 can continuously drain the condensed water into the water receiving bucket 75.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
