1. Product overview

According to the "Professional Teaching Standards for Higher Vocational Schools" and industry standards, the Machinery Installation Experiment Shelter combines "mechanical manufacturing and automation", "mechanical and electrical equipment installation and m--ntenance", "mechanical assembly", "mechanical equipment assembly and automatic control" "And" construction machinery use and m--ntenance "and other professional tr--ning goals. Through project tr--ning, we m--nly cultivate students' reading and matching pictures and components; the assembly and adjustment of mechanical parts; design and m--ntenance of electrical control lines; inverter, servo motor and drive, step motor and drive application; PLC control program writing and and Debug; mechanical equipment installation, adjustment of the whole machine operation, and other occupational capabilities, improve students in the first -tier process assembly and implementation of mechanical equipment, electromechanical equipment enterprises and related industries, mechanical and electrical equipment installation, commissioning and m--ntenance, mechanical equipment electrical control, mechanical processing quality analysis and control , Employment capacity of grass -roots production management and other positions.

2. Functional characteristics

1. High simulation device can simulate the real CNC punch processing parts. Through the combined action of feeding system, positioning system, stamping system, and cold stamping molds, it can be accurately processing aluminum plates below 5mm. After the programming is completed, it can be automatically processed by the parts, which is close to the actual operation of the industrial site.

2. Strong practical practice to set up various practical work tasks in accordance with relevant national occupational standards, industry standards and job requirements. Taking professional practice activities as the m--n line, through "doing middle schools", it truly improves students' hands -in skills and employment ability.

3. Modular design consists of a variety of mechanical parts. Each component can be tr--ned as an independent module, and each component can be composed of a comprehensive mechanical system for tr--ning.

4. Comprehensive strong device can complete typical work tasks such as mechanical equipment installation and adjustment, electrical design and line connection, PLC and touch screen preface, mechanical and electrical joint adjustment, assembly accuracy detection Essence
