Description

DETAILED DESCRIPTION OF THE INVENTION This invention, C, relates to a device for pulling out the end of a high-pressure hose. The entire blade is attached with a separating plate that can be moved in the pulling direction, and the blade is bitten into the blade. Move the flu plate and remove the end of the pressure hose?
By pulling out the end part from the iron core, the end part can be pulled out safely and with high efficiency without damaging the main body part and the iron core of the high pressure hose.

In general, a still-pressure hose is manufactured by coating an iron core (mandrellon) with tube rubber, a reinforcing layer of steel wire, cover rubber, etc., and vulcanizing it in this state. In order to pull out a high-pressure hose with an iron core inserted from the iron core, it is necessary to provide a flange allowance on the iron core, so the end of the high-pressure hose is cut off and only this end is pulled out and removed from the iron core. .

Conventionally, to pull out the entire end of a high-pressure hose with an iron core, the method was to clamp and fix the entire chamber pressure hose body near the end, and then gradually pull it out while hitting the end with a piece of iron you have. It is taken. However, with this method, there is a problem that the nailing easily damages the entire core, and the core cannot be reused unless it is repaired to smooth the surface. In addition, the clamp portion of the main body of the pressure hose is easily damaged, and there is a problem in that the cut-off portion, which cannot be used as a product, becomes stronger. Furthermore, in the work of nailing down iron pieces on hand, there is a problem that not only is there a risk that the worker may place the iron pieces, but also that favorable results cannot be obtained in terms of work efficiency.
