专用多层液压机是生产鉋花板的主要自动化设备。目前,苏联已掌握了N P—6型鉋花板液压机的生产技术,而且还设计了结构更加完善的П763А和Д4743型大型多层液压机。但这些液压机液压系统工作时,其压板是自下而上依次闭合的,故总的团合时间需要30～60秒钟。由于受鉋花板生产工艺特点所限,这个时间不能再进一步缩短。因此,现有鉋花板液压机的压板闭合方式已不能满足鉋花板生产工艺过程的要求。近年
Specialized multi-layer hydraulic press is the main automation equipment for the production of particleboard. At present, the Soviet Union has mastered the production technology of N P-6 particleboard hydraulic press, and also designed a more complete structure of large multi-layer hydraulic press П763А and Д4743. However, these hydraulic machine hydraulic system work, the pressure plate is closed from bottom to top, so the total time required for the integration of 30 to 60 seconds. Due to the characteristics of the particle board production process is limited, this time can not be further shortened. Therefore, the existing particleboard hydraulic press plate closure method can not meet the particleboard production process requirements. in recent years
