Mechanical design, according to the requirements of use, conceive, analyze and calculate the working principle, structure, movement mode, force, and energy transmission mode, material and shape size of each part, lubrication method, etc. and convert it into a specific description to The working process as the basis for manufacturing.
1. Multifunctional design of components
The so-called multifunctional component means that a component has multiple functions. Multiple useful actions can be generated during the operation of the mechanism.
For example: in the feeding mechanism, the pushing member has both the function of pushing the material in place and the function of positioning and clamping. In the clamping mechanism, the pressing member has both the function of pressing and the function of positioning; the mechanism is in a reciprocating motion. In, the trip switch touches the member. It not only plays the role of triggering the mechanism for reverse movement, but also has the function of pushing the counter to record.
The design of multi-functional components can make the structure simple, compact and dexterous, and make the mechanism run stably and reliably.
2. The movement exchange mechanism is simple and reliable
In the design of the motion conversion mechanism, a reasonable mechanism should be selected according to the functional requirements and technical conditions used, and the mechanism can be simple and reliable to realize the conversion of the movement form and direction and facilitate the adjustment of the force and the working position.
The selection of the mechanism type should consider its inherent characteristics, for example, the deceleration mechanism must have the function of saving effort and running smoothly. On the contrary, the speed-increasing mechanism does not save effort nor is stable, but it has the effect of increasing the stroke (or increasing the angle of rotation) and delay.
The service area of mechanical engineering is broad and multi-faceted. Any department that uses machinery, tools, and even energy and material production needs mechanical engineering services.
In a nutshell, modern mechanical engineering has five major service areas: development and provision of energy conversion machinery, development and provision of machinery for the production of various products, development and provision of machinery for various services, development and provision of applications in home and personal life The machinery, development and supply of various mechanical weapons.
No matter which field it serves, the work content of mechanical engineering is basically the same, mainly including:
Establish and develop the engineering theoretical foundation of mechanical engineering. For example research on engineering mechanics and fluid mechanics of force and motion; research on the properties of metal and non-metal materials and engineering materials science of their applications; research on thermodynamics of heat generation, conduction, and conversion; research on various mechanical components with independent functions The working principle, structure, design, and calculation of mechanical principles and mechanical parts; research on metal and non-metal forming and cutting of metal technology and non-metal technology, etc.
Research, design and develop new mechanical products, continuously improve existing mechanical products and produce new-generation mechanical products to meet current and future needs.
The production of mechanical products includes planning and realization of production facilities; formulation and production scheduling of production plans; preparation and implementation of manufacturing processes; design and manufacture of tools and molds; determination of labor quotas and material quotas; organization of processing, assembly, test run and packaging Shipment; effective control of product quality.
Operation and management of machinery manufacturing enterprises. Machinery is generally a complex product assembled from many precision parts with unique forming and processing processes. There are single and small batches in production batches, as well as medium batches and large batches, up to mass production.
The sales targets cover all industries and individuals and families. Moreover, the sales volume may fluctuate greatly under the influence of social and economic conditions. Therefore, the management and operation of machinery manufacturing enterprises are particularly complicated, and the research on production management, planning and operation of enterprises also originated in the machinery industry.
The application of mechanical products includes selection, ordering, acceptance, installation, adjustment, operation, maintenance, repair and transformation of machinery and complete sets of mechanical equipment used in various industries to ensure the reliability and economy of mechanical products in long-term use.
Research the problems of environmental pollution and excessive consumption of natural resources during the manufacturing process of mechanical products, especially in use, and their treatment measures. This is a particularly important task of modern mechanical engineering, and its importance is increasing day by day.
