Ring-removing mechanism for single-head large-cylinder-diameter nodular cast iron piston ring

Abstract

The invention discloses a ring-removing mechanism for a single-head large-cylinder-diameter nodular cast iron piston ring, and belongs to the technical field of piston ring machining. A workbench is vertically provided with at least three supporting rods in a fixed manner, and the supporting rods support one horizontal cover plate. The center of the cover plate is connected with a telescoping rod which passes through a vertical impact cylinder in a central hole of the cover plate. An inner side of a space formed by the enclosing of the supporting rods is provided with a rear baffle plate in a vertical manner. The workbench is also fixedly provided with a horizontal clamping cylinder, and the tail end of the telescoping rod is fixedly connected with a front baffle plate. When the horizontal clamping cylinder shrinks, the front baffle plate and the rear baffle plate surround a piston ring blank disposed between the front and rear baffle plates. The mechanism provided by the invention can enable the ring removal of the single-head large-cylinder-diameter nodular cast iron piston ring to be completed conveniently and reliably, reduces the rejection rate, and reduces the labor intensity of workers.

Description

technical field [0001] The invention belongs to the technical field of piston ring processing, in particular to a mechanism for separating a piston ring blank from a runner therein. Background technique [0002] At present, after the general piston ring casting process, the operator can easily separate the piston ring blank from the runner by hand or auxiliary tools, but for the single-head large-bore ductile iron piston ring, the traditional ring removal scheme cannot or is not easy The blank and the runner are separated, and the staff generally use special methods to carry out the de-ring work of such piston ring castings, such as hitting with a sledgehammer. The biggest disadvantage of this method is that it is easy to cause deformation of the piston ring blank, resulting in high waste products rate, while the labor intensity of workers is relatively high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the pri...
