一、概论锻压设备的种类和形式很多,如各种功率和轮廓尺寸的开式压力机和闭式单、双点压力机、空气锤、蒸汽锤、立式及卧式水压机和油压机以及平锻机、冷镦机、热模锻压力机和剪床等等。在我国,制造上述锻压设备,基本上是采用企业专门化,即按照机器结构一制造工艺特点的类似性,在某个工厂(或车间)只制造有限的机器类别。重型和大型锻压设备是单件和小批生产,中型和小型锻压设备则属于小批及成批生产的类型。生产类型不同,在生产组织、生产管 I. Introduction Forging equipment of many types and forms, such as a variety of power and contour dimensions of the open press and closed single, double point press, air hammer, steam hammer, vertical and horizontal hydraulic and hydraulic presses and forging Machine, cold heading machine, hot die forging press and shearing machine and so on. In our country, the above-mentioned forging equipment is basically manufactured using a specialization of the firm, that is to say, according to the similarities of machine structure-manufacturing process characteristics, only a limited number of machines are manufactured in one factory (or workshop). Heavy and large forging equipment is single and small batch production, and medium and small forging equipment is a small batch and batch production type. Different types of production, production organization, production management
