A high-frequency longitudinal-torsion compound vibration sponge drilling device and its application

Abstract

The invention particularly relates to a high-frequency longitrorse compound vibration sponge perforating device and application thereof; the device is mainly used for processing elastic layers of transfer printing rollers of printing and copying machines. The high-frequency longitrorse compound vibration sponge perforating device comprises an ultrasonic generator, an ultrasonic transducer connected with the ultrasonic generator via a lead wire, at least one stage of amplitude-variable rod connected with the ultrasonic transducer, and a tubular cutter connected with the amplitude-variable rod, wherein the tubular cutter is in threaded connection with the amplitude-variable rod; the tubular cutter comprise a connector connected with the amplitude-variable rod, a tube body with an inner cavity and a cutting edge; one end of the tube body is in threaded connection with the connector; the cutting edge is formed in the other end of the tube body; a longitrorse compound vibration conversion structure is arranged on the tube body. Through the technical scheme, holes are easily perforated in sponge; the aperture size accuracy is high; the surfaces of the holes are smooth and damage-free; the product qualification ratio is greatly improved; the production efficiency is significantly improved.

Description

technical field [0001] The invention belongs to the sponge processing technology, and in particular relates to a high-frequency longitudinal-torsion compound vibration sponge drilling device and its application, which are 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 tra...
