Abstract

The utility model discloses a kind of wire cutting working solution reflux, including：Tank, water tank and tapping pipe, one end of the tapping pipe are connected with tank, and the other end is connected with water tank, and the tapping pipe is one time punching molded, and it includes：Body, the first bending part positioned at the body top, the second bending part positioned at the body bottom, passage is being offered on the body tube wall of first bending part, unidirectional air pressure valve is installed on the passage, when reflux does not work, the unidirectional air pressure valve is closed to cover in the passage.Through the above way, the utility model is simple in construction, can effectively exclude in tapping pipe by the air of embolism, makes working solution backflow smooth, no longer blocks, while provided with unidirectional air pressure valve, being avoided that dust blocks passage.

Description

A kind of wire cutting working solution reflux

Technical field

The utility model is related to wire cutting machine accessory field, more particularly to a kind of wire cutting working solution reflux.

Background technology

The principle of wire cutting machine is suitably to be tensioned wire electrode, and with certain speed and pressure, relative to cut Workpiece is reciprocating, during cutting on line, makees to ensure that cutting processing process can continuously and effectively produce spark discharge With, and in time from machining area galvanic corrosion product and heat are excluded, it is necessary to continuous fully in cutting processing region Wire electrode rushes cleaning liquid（Generally water）, the working solution after flushing flow back into water by tapping pipe from the tank of cutting machine again In case, but be due to the architectural feature of wire cutting machine, tapping pipe is unavoidably provided with bending part, tapping pipe bending part usually Working solution deposition is had, and the junction working solution flow of tank and tapping pipe is big, therefore easily cause in tapping pipe " stifled Gas ", the working solution in tank is prevented because of air embolism from the inlet water tank that smoothly flows down, and then working solution is overflow cutting machine lathe Upper pollution lathe, or even flow to the serious consequence such as initiation fire on electrical equipment.

Utility model content

The utility model can solve the problem that existing mainly solving the technical problems that provide a kind of wire cutting working solution reflux With the presence of the defect of wire cutting return duct.

In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of wire cutting work is provided Liquid reflux, including：Tank, water tank and tapping pipe, one end of the tapping pipe are connected with tank, and the other end connects with water tank Connect, the tapping pipe is one time punching molded, and it includes：Body, the first bending part positioned at the body top, positioned at institute The second bending part of body bottom is stated, passage, the ventilation are being offered on the body tube wall of first bending part Unidirectional air pressure valve is installed, when reflux does not work, the unidirectional air pressure valve is closed to cover in the passage on hole.

In one preferred embodiment of the utility model, the unidirectional air pressure valve includes valve rod and on the valve rod Door, the lower end of the valve rod is stretched into the passage, when reflux does not work, and the door is closely knit to be covered On the passage.

In one preferred embodiment of the utility model, the tapping pipe is one time punching molded using 304 stainless steels.

The beneficial effects of the utility model are：A kind of wire cutting working solution reflux of the utility model, by sluicing First bending part annex of pipe opens up passage, for excluding in tapping pipe by the air of embolism, makes working solution backflow smooth, no Block again, while being provided with unidirectional air pressure valve on passage, when reflux does not work, unidirectional air pressure valve is closed to be covered in The passage, it is to avoid dust blocks passage.

Brief description of the drawings

Fig. 1 is a kind of structural representation of the preferred embodiment of wire cutting working solution reflux one of the utility model；

Fig. 2 is the structural representation of unidirectional air pressure valve shown in Fig. 1；

The mark of each part is as follows in accompanying drawing：1st, tank, 2, water tank, 3, tapping pipe/body, 4, passage, 5, unidirectional gas Pressure valve, the 31, first bending part, the 32, second bending part, 51, valve rod, 52, door.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite Define.

Fig. 1 and Fig. 2 are referred to, the utility model embodiment includes：

A kind of wire cutting working solution reflux, including：Tank 1, water tank 2 and tapping pipe 3, one end of the tapping pipe 3 It is connected with tank 1, the other end is connected with water tank 2, the tapping pipe 3 is, through one time punching molded, to have using 304 stainless steels Good intensity and service life；The tapping pipe 3 includes：Body 3, the first bending part 31 positioned at the top of body 3, position The second bending part 32 in the bottom of body 3, sets two bending part structures, can make the compact conformation of reflux, fits It is advantageously mounted in wire cutting machine tool；Passage 4 is being offered on the body tube wall of first bending part 31, for excluding By the air of embolism in tapping pipe, make working solution backflow smooth, no longer block, unidirectional air pressure valve is installed on the passage 4 5, when reflux does not work, the unidirectional air pressure valve 5 is closed to cover in the passage 4, it is to avoid dust blocks passage 4, it is ensured that reflux uses reliability.

Wherein, the unidirectional air pressure valve 5 includes valve rod 51 and the door 52 on the valve rod 51, the valve rod 51 Lower end stretch into the passage 4, when reflux works, the air pressure risen in tapping pipe 3 pushes up the valve rod 51 Go out, door 52 is separated with passage 4, the air in tapping pipe 3 is discharged from passage 4, so that working solution backflow is smooth；When When reflux does not work, the door 52 is closely knit to be covered on the passage 4, it is to avoid dust blocks passage 4.

The utility model discloses a kind of wire cutting working solution reflux, passes through the first bending part annex in tapping pipe Passage is opened up, for excluding in tapping pipe by the air of embolism, makes working solution backflow smooth, no longer blocks, while in ventilation Unidirectional air pressure valve is installed, when reflux does not work, unidirectional air pressure valve is closed to cover in the passage on hole, it is to avoid ash Dirt blocks passage.

Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in Other related technical fields, are similarly included in scope of patent protection of the present utility model.
