机械压力机的大型化,是在被加工件的大型化和大型立式连续式自动压力机的实用化中发展起来的。被加工件的大型化:机械压力机在板材塑性加工方面,由于具有适应大量生产的时代特点,因此被加工件的范围扩大了,大型加工件成了它的加工对象。压制卡车底梁的大型钢梁压力机就是其中的代表。大型连续式自动压力机:它是把原来的在数台压力机组成的压机生产线上,逐个工序进行加工的方式改为由一台大型压力机完成全工序的加工方式,它是一台具有自动运
The enlargement of the mechanical press has been developed in the field of large-sized workpieces and the practical use of large-scale vertical continuous automatic presses. Large-scale processing of the workpiece: Mechanical presses in sheet metal plastic processing, due to the characteristics of the times to adapt to mass production, so the scope of the workpiece to be enlarged, large-scale processing has become its processing object. One of the representatives is the large steel beam press that presses the bottom beam of a truck. Large continuous automatic press: It is the original press in the press composed of the production line, the process of processing one by one to a large press to complete the whole process of processing, it is a set with Automatic transport
