Abstract

The invention discloses hose assembly crimping equipment. A driving plate is connected on a driving shaft of a hydraulic cylinder and is provided with a fixture for fixing a slug, the front end of the slug is fixed on the fixture, the center of the driving plate is provided with a first through hole, the center of the fixture is provided with a second through hole, the first through hole, the second through hole and the slug are positioned on the same axis, one end of a pull rod is fixed on a fixing plate while the other end of the pull rod respectively penetrates through the first through hole and the second through hole, and an expanding bit is fixed at the other end of the pull rod and is positioned at the rear end of the slug. The hose assembly crimping equipment has the advantages that the expanding bit enables inner holes of a middle section and a rear section of the slug to be expanded, and the slug walls of the middle section and the rear section of the slug are deformed, so that an annular groove between an outer sleeve and the slug deforms to clamp and fix a hose; and compared with traditional crimping process, the hose assembly crimping equipment cannot enable the hole diameter of the slug to be diminished, and under the same liquid pressure, a hose assembly assembled by the hose assembly crimping equipment is longer in service life.
