Method for cutting sponge-liked sound-absorbing material for wall by hydraulic press

Abstract

The present invention discloses a method which uses a hydrostatic press to cut a spongy sound-absorbing wall material. The cutting of a spongy sound-absorbing wall material workpiece needing to be cut is programmed according to a required size; then concrete values on travel length, differential, blanking force and speed are determined; finally, a cutting procedure is started, so that the hydrostatic press can cut the workpiece according to the predesigned requirements into a workpiece meeting the requirements. The method improves material precision, and the cut surface is uniform and is not coarse; during processing, a spongy workpiece can be produced in the absence of pressure by adopting the electrohydraulic technology; moreover, characterized by high efficiency and low labor intensity, the method is adapted to mass mechanical production.

Description

technical field [0001] The invention relates to the technical field of electro-hydraulic cutting, in particular to a processing method for electro-hydraulic cutting of "sponge" wall sound-absorbing materials. Background technique [0002] At present, the cutting and processing of "sponge" wall sound-absorbing materials are still carried out by traditional manual methods, which have insufficient precision requirements, uneven cutting surface, and roughness; the "sponge" shape cannot be obtained without pressure during processing. In addition, due to the low efficiency and high labor intensity of traditional methods, it cannot adapt to large-scale mechanized production. Contents of the invention [0003] The object of the present invention is to provide a method for cutting "sponge" wall sound-absorbing material by using electric and hydraulic technology. [0004] In order to solve the above technical problems, a method of cutting "sponge" wall sound-absorbing materials wit...
