High pressure hoses (HPH) are part of the hydraulic system and represent a flexible pipeline equipped with end fasteners. Due to the specifics of their application, they are practically consumables and can fail in case of sudden pressure surges, mechanical damage and a number of other cases. In turn, a long downtime of equipment until a replacement is found is economically unprofitable. Enterprises that massively use RVD in hydraulic systems prefer to independently produce such parts. On the site http://rvd-stanki.ru/ you can familiarize yourself with the main types of machines that will be needed to make high pressure hoses. p>
Machine tools for the production of high pressure hoses
As mentioned above, a high-pressure hose is a flexible rubber or polymer hose with an internal metal winding or braid. The technology for obtaining high pressure hoses of the required design consists in obtaining a workpiece of the required length, its preliminary processing, installation of an end seal and its crimping. For this, the following types of machines are used.
Cutting machines
Used to obtain a sleeve of the appropriate length by cutting it crosswise with an abrasive disc. In addition, they are completed with a stand for the bay, measuring devices, a feeding table and a parts receiving tray.
Debarkers
They are used for gentle removal of the outer and inner layers of polymer or rubber up to the first fragment of the metal braid. This operation subsequently ensures full contact of the end-fitting elements with the hose, which is impossible in the presence of an outer and inner rubberized layer.
Swaging presses
End seal is a prefabricated element consisting of a fitting whose diameter corresponds to the inner section of the hose and a sleeve in diameter that coincides with the outer size of the hose after processing on a debarking machine. The working body of the press is a chuck with cams that evenly crimp the end seal sleeve after it is mounted on the hose.
In conclusion, we note that all of the above equipment, except for the stationary version, can be produced in a portable (manual) version, which is demanded by field repair teams.
