Preliminary recognition device of metal material

Abstract

The invention belongs to the technical field of machinery, relates to a preliminary recognition device of a metal material and solves the problem that existing metal material recognition methods are low in accuracy and efficiency. The preliminary recognition device comprises a platform, a grinding wheel is rotatably arranged at the front end of the platform, a first driving source capable of driving the grinding wheel to rotate is arranged on the platform, a clamp for clamping the metal material is arranged above the grinding wheel and arranged on the platform through a second driving source, and the second driving source can drive the clamp to move towards the grinding wheel to enable the metal material on the clamp to contact with the grinding wheel; a passage for spark generated when the metal material contacts with the grinding wheel is arranged on the platform, and an image collection system capable of performing photographing collection on the spark is arranged on the side face of the passage and is connected with an image recognition system capable of recognizing spark type. The preliminary recognition device can recognize the metal material accurately and quickly.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a preliminary identification device for metal materials. Background technique [0002] Metal materials are rich in sources and have excellent performance and processing performance. They are the most commonly used materials in mechanical engineering. They are often used to manufacture mechanical equipment, tools, and molds, and are widely used in engineering structures. Metal materials can be roughly divided into two categories: ferrous metals and non-ferrous metals. Ferrous metals usually refer to steel and cast iron; non-ferrous metals refer to metals other than ferrous metals and their alloys, such as copper alloys, aluminum and aluminum alloys. [0003] At present, when identifying metal types, metallographic analysis is usually used, and the steps of metallographic analysis are relatively cumbersome, usually requiring the following steps: [0004] 1. Select the sampling sit...
