What is the formal principle of machining workshop layout?

According to the principle of workshop equipment layout, according to the divided production lines and parts process flow, the equipment layout generally has the following forms.

1. Arrange equipment according to the sequence of process flow, which is suitable for automatic production line and assembly line.

2. The equipment is relatively arranged according to the process flow, which is suitable for assembly line and batch production line.

The layout should try to avoid backflow and circuitous. The inlet end and outlet end of a production line with the above two arrangements are usually in two opposite directions.

3. u-shaped arrangement. U-shaped layout is a novel layout form, especially suitable for assembly lines managed by multiple machine tools.

4. Kneading production system. The kneading production system is generally composed of various CNC machine tools, machining centers, automatic shaft changing machine tools, automatic conveying devices, automatic detection devices, automatic warehouses and other auxiliary facilities. The whole system is controlled by computer, the system layout is very compact, and the related elements are closely combined to maximize the utilization rate of machine tools and labor productivity.

principle

1, principle of process specialization

According to the principle of process specialization, the production unit is formed. Because the same type of process assembly and the same type of processing methods are concentrated together, this layout is suitable for small-scale production and small-batch production.

2. Principle of object particularity

The principle of object-oriented specialty is to set up production units based on products (parts). In specialized production units, different types of production equipment and different types of workers are concentrated, and they are responsible for processing products with different technological methods. Each production unit can basically complete all or most of the process flow of the product independently without the help of other production units.

3, the principle of mixing

In order to concentrate the advantages of the above two principles and avoid their disadvantages, in actual production, we can combine them to foster strengths and avoid weaknesses, which is the so-called mixed principle. In such a workshop, some sections or teams may be established according to the principle of process specialization, while others may be established according to the principle of object specialization.

For some large or isolated forging press, electroplating and heat treatment equipment, it is necessary to adopt the organization form of process specialization, and for mass-produced parts, it is necessary to adopt the organization form of object specialization.

Extended data

Workshop layout refers to the overall arrangement of basic workshops, auxiliary workshops, production service departments, facilities, equipment, warehouses, passages and other mutual positions. In space and on the plane. Workshop layout aims to make the most effective use of workshop space, on the one hand, it is convenient for work and operation, and avoids the overcrowding of production equipment; On the other hand, pay attention to the ventilation, fire prevention and explosion prevention of the factory building to ensure safe production. Its specific contents include:

1. Layout of longitudinal span, span, high span and open-air span construction area;

2. Arrangement of workshop space stratification;

3. Layout in multi-storey buildings.

Workshop layout should be determined according to the production outline and division of labor table, production technology, process route, production organization form, types, models and quantities of mechanical equipment and lifting and transportation equipment. A good workshop layout should minimize the transportation distance, so that the materials will flow through each station in turn after entering the workshop, and then flow out of the workshop.
