A high-frequency vertical-torsion compound vibration sponge strip-taking device and its application

Abstract

The invention particularly relates to a high-frequency longitudinal-torsional composite vibratory sponge bar taking device and application. The high-frequency longitudinal-torsional composite vibratory sponge bar taking device is mainly used for processing of an elastic layer on a transfer roller in a printing and copying machine. The high-frequency longitudinal-torsional composite vibratory sponge bar taking device comprises an ultrasonic generator, an ultrasonic transducer connected with the ultrasonic generator through a lead, at least one stage of a variable-amplitude pole connected with the ultrasonic transducer and a tubular cutter connected with the variable-amplitude pole, wherein the tubular cutter is in threaded connection with the connected variable-amplitude pole and comprises a connector connected with the variable-amplitude pole, a tube body with a cavity and a cutting edge, one end of the tube body is in threaded connection with the connector, the cutting edge is arranged at the other end of the tube body, and a circular-arc transitional structure is arranged at the connecting position of the tube body and the connector. A longitudinal-torsional composite vibratory transformational structure is arranged on the tube body. By the adoption of the technical scheme, bar taking on sponge is easily achieved in a high-frequency vibratory mode, the bar taking process is stable, the hole diameter accuracy is high, the wall surface of a hole is flat and damage-free, the product percent of pass is remarkably improved, and the production efficiency is obviously improved.

Description

technical field [0001] The invention belongs to the sponge processing technology, and in particular relates to a high-frequency longitudinal-torsion composite vibrating sponge strip-taking device and its application, which is mainly used for processing the elastic body layer on the transfer roller in a printing copier. Background technique [0002] In daily life or industrial products, there are many cases where chipping processing is required on elastic materials such as artificial sponge, foam rubber, etc., but the above materials are easily deformed under slight pressure or torsion and tend to resist movement through compression or deformation. cutting or drilling action. [0003] The transfer roller of a printer or copier generally includes a metal mandrel and an elastomer layer sleeved outside the metal mandrel. The elastomer layer is usually the above-mentioned elastic material. In order to set the inner mandrel, holes need to be opened on the elastic material. . The...
