Auxiliary equipment capable of utilizing sound wave phase difference for hardware cutting

Abstract

The invention relates to the technical field of hardware cutting and discloses auxiliary equipment capable of utilizing the sound wave phase difference for hardware cutting. The auxiliary equipment comprises a support frame, wherein a shell is in sliding fit with the surface of the support frame; a clamping mechanism is movably connected with the lower side of the shell; a hollow passage is fixedly connected with the interior of the shell; an air hole is formed in the surface of the hollow passage; the surface of the air hole is movably connected with the clamping mechanism; the surface, on the two sides of the air hole, of the hollow passage is fixedly connected with a straight tooth rod; and the surface of the straight tooth rod is meshed with a gear. The shell slides on the support frame up and down; when the hollow passage is inflated, the airflow ejects out of the air hole and flows into the clamping mechanism; the flow velocity of the air flow is weakened along with increase of the distance, so that the extrusion force of the airflow to a spring is also reduced along with increase of the distance, and on the contrary, the extrusion force is increased along with decrease of the distance; and by utilizing the characteristic, the clamping intensity of a to-be-cut object can be controlled to realize the effect of precisely positioning the cutting position.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to an auxiliary device for metal cutting by using sound wave phase difference. Background technique [0002] Hardware: Refers to five metals including gold, silver, copper, iron and tin, which can be made into knives, swords and other works of art or metal devices through manual processing. With the formation of modern industrialized society, the metal hardware industry is developing rapidly. The industry has played an inestimable role in the development of the national economy, and hardware products have also become an indispensable part of industrial manufacturing. [0003] Due to the characteristics of metal, the following phenomena will occur when cutting and processing hardware materials: 1. The shape and size of the metal blank are not fixed, and it is not convenient to accurately locate the cutting position, and the metal debris generated by cutting is not processed in ...

[0003] Due to the characteristics of metal, the following phenomena will occur when cutting and processing hardware materials: 1. The shape and size of the metal blank are not fixed, and it is not convenient to accurately locate the cutting position, and the metal debris generated by cutting is not processed in time, which may easily lead to Damage to the internal parts of the device; 2. There will be a lot of noise when cutting, without noise reduction treatment, it is easy to cause harm to people's body and mind; therefore, an auxiliary equipment that uses sound wave phase difference for metal cutting came into being.
