Description

[Detailed description of the invention] The present invention relates to a hydraulic wire drawing machine.

This hydraulic wire drawing machine extrudes the raw material wire from a die using the hydraulic pressure of high-pressure liquid in a pressure vessel (an auxiliary ζ-drawer may be added).

) is used for wire drawing.

This product has the effect of allowing a large extrusion ratio.

However, since this structure uses high-pressure liquid,
Dust such as dirt, textile scraps, metal powder, etc. mixed or floating in the high-pressure liquid could adhere to the inlet of the die, causing clogging of the die, resulting in poor wire drawing or wire breakage. .

For this reason, we pass the high-pressure liquid through a filter member at the stage of feeding it into the pressure vessel to prevent dust from entering the pressure vessel. At this time, dust enters the pressure vessel from the outside and adheres to the lid member of the opening, resulting in dust mixed in the high-pressure liquid. The above-mentioned problems caused by dust have not been eliminated.

The present invention aims to provide a dust removal device for a liquid wire drawing machine that can eliminate these disadvantages.

The invention will now be described with reference to the accompanying drawings.

In this device, a coil wire 2 is installed inside a pressure vessel 1, a die 4 is arranged in an opening 3 of the pressure vessel 1, and the coil wire 2 is connected to the pressure of the high-pressure liquid 5 in the pressure vessel 1. In a hydraulic wire drawing machine that draws wire by extruding it from the die 4, the coil material wire 2 is housed in the pressure vessel 1, and a filter cylindrical member 6 that covers the inlet portion 4a of the die 4 is installed inside the pressure vessel 1. The hydraulic expansion is characterized in that the filter cylinder member 6 is configured to remove dust and the like mixed in the high-pressure liquid 5 and prevent the dust and the like from flowing into the inlet portion 4a of the die 4. This is a dust removal device for line machines.

Further, this example will be specifically explained in detail.

The pressure vessel 1 of this embodiment consists of a base body 1a and a lid member 1b, a liquid feeding hole 7 is formed in the side, the lid member 1b is screwed, and a through hole 8 is formed in the center. There is.

Further, the die 4 of this embodiment has a holding piece 1 having a lead-out hole 9 at the center and a packing member 10 arranged on the outer peripheral surface.
1, and a pedestal 13 having a passage hole 12 is screwed onto this holding piece 11.

Further, the filter cylinder member 6 of this embodiment includes an outer cylinder 5a having a liquid passage port 14 and an inner cylinder 5b formed of a net member, and is attached to the pedestal 13.

Further, a guide roller 15 is located outside the lid member 1b.

Further, the coil material wire 2 of this embodiment is housed in a support tube 16, and the support tube 16 is housed within the filter tube member 6.

Since this embodiment has the above configuration, the coil material wire 2 is installed inside the filter cylinder member 6, and the coil material wire 2 is inserted into the die 4.
Pull it out (make the terminal part thin so that it can be pulled out).

) Hang it on the guide roller 15, screw the pedestal 13 onto the holding piece 11, insert the holding piece 11 into the opening 3, screw the lid member 1b onto the base 1a, and seal the inside of the pressure vessel 1. .

In this state, when high-pressure liquid (oil, water, etc.) is fed through the liquid feeding hole 7, the coil material wire 2 is pushed out from the die 4 by the hydraulic pressure of the high-pressure liquid 5 and drawn.

Further, dust and the like in the high-pressure liquid 5 are removed by the filter cylinder member 6, and are prevented from flowing into the inlet portion 4a of the die 4.

As described above, in this case, the coil material wire 2 is housed in the pressure vessel 1, and a filter cylinder member 6 that covers the inlet portion 4a of the die 4 is installed inside the pressure vessel 1. Since the structure is configured to remove dust mixed in and prevent the dust from flowing into the inlet portion 4a of the die 4, it is possible to prevent the dust from entering the pressure vessel 1 from the outside when replenishing the coil material wire 2, etc. Even if there is dust, the filter cylinder member 6 removes it, and it is possible to reliably prevent the dust from adhering to the artificial part 4a of the die 4 and from clogging the die 4 due to this. Wire drawing processing is possible and work efficiency can be improved.

As described above, the intended purpose can be fully achieved.
