Description
Technical Field
The invention relates to the technical field of metal wire drawing, in particular to an in-mold oil-gas lubricating mechanism of a WDC440301 type wire drawing machine.
Background
In the prior art, a wire drawing machine produces friction between a metal wire and a mould in the process of drawing the metal wire, so that a large amount of heat energy is generated, the temperature of the mould and the metal wire is increased, the current lubricating mode of the wire drawing machine to the mould is shower lubrication, the mode is that in the process of drawing the wire, a flywheel rotates to throw up wire drawing oil in a wire drawing cavity and splashes the wire drawing oil on the surface of the mould to cool the mould, the quantity of the wire drawing oil which can enter the inner friction surface of the mould is inaccurate, and the arriving position is uncertain, so that the condition that the wire is broken due to excessive heating of the mould is easily caused, and the service life of the mould is relatively short. Meanwhile, the consumption of the existing wire drawing machine to the wire drawing oil is large, and metal powder generated in the wire drawing process can enter the wire drawing oil, so that impurities in the wire drawing oil are more, the wire drawing quality of a die can be influenced, the service life of the wire drawing oil is short, and the waste oil is difficult to treat.
Disclosure of Invention
The invention aims to solve the technical defects and provide an in-die oil-gas lubricating mechanism of a WDC440301 type wire drawing machine, which can accurately supply oil to and cool a wire drawing inner die.
In order to achieve the purpose, the invention provides an in-mold oil-gas lubricating mechanism of a WDC440301 type wire drawing machine, which comprises an inner mold of the wire drawing machine and an oil-gas supply station, wherein the inner mold of the wire drawing machine is arranged in a wire drawing cavity of the wire drawing machine at intervals in a row through mold bases, a free-rotating flywheel is arranged in the wire drawing cavity between two adjacent mold bases, metal wires sequentially pass through the inner mold, and the metal wires between the adjacent inner molds are wound on the flywheel for one circle or a plurality of circles; and a nozzle is arranged on the side edge of each die holder and is connected with an oil-gas supply station through an oil-gas conveying pipeline, and oil gas sprayed by the nozzles is sprayed on the corresponding inner die or a metal wire before entering the corresponding inner die. The inner die is a wire drawing die arranged on the die holder, and a wire drawing hole is formed inside the inner die.
Above-mentioned technical scheme, in the in-service use process, the oil gas supply station passes through highly-compressed air with drawing oil and carries to every nozzle, the nozzle is glib talker promptly, can directly spray mixed oil gas on the wire before getting into the centre form for there is drawing oil at the friction surface of wire and centre form all the time, thereby cools off the centre form, also can directly spray mixed oil gas in centre form and wire contact department, is about to spray oil gas on the friction surface of wire and centre form, and its cooling effect is better. The inner die is cooled in the form, so that the wire drawing oil obtained by the inner die is fresh and clean, the oil consumption can be reduced, the use amount of the wire drawing oil used in the mode is about 10% of the oil consumption in the original process, and the wire drawing quality can be ensured. Wherein WDC440301 is the type of a wire drawing machine.
The nozzle is of a circular ring structure, an oil-gas channel communicated with an oil-gas conveying pipeline is arranged in the nozzle, and an outlet of the oil-gas channel is annularly arranged. The outlet of the oil-gas channel is of a flat annular structure or is independent nozzles arranged at intervals in an annular shape. According to the technical scheme, the mixed oil gas is sprayed from the annular outlet, so that the wire drawing oil can be sprayed to the whole annular direction of the friction surface of the metal wire or the inner die, the cooling performance of each direction can be ensured, and the wire drawing process is more stable.
And a metal powder collecting device is arranged in a wire drawing cavity of the wire drawing machine. Preferably, the metal powder collecting device is a pulse bag dust collector. Certainly, the device can also be a dust collecting device in other forms, and only metal powder generated in the wire drawing process needs to be collected in time, so that accidents such as dust explosion and the like are avoided.
And a cooling water channel is arranged in the die holder and is connected with a cooling water source through a pipeline and a water pump. Because the metal wire can produce a large amount of heat energy in the cold drawing process, the die holder and the inner die on the die holder are cooled by utilizing the circulating cooling water when the circulating cooling water passes through the cooling water channel.
According to the in-mold oil-gas lubricating mechanism of the WDC440301 type wire drawing machine, which is disclosed by the invention, through reasonable structural design, the accurate cooling of the inner mold of the wire drawing machine can be effectively realized, the wire drawing oil can be sprayed to the wire drawing friction surface of the inner mold, the cooling effect and the wire drawing effect are ensured, and meanwhile, the using amount of the wire drawing oil can be greatly reduced.
