预压增压器
本技术涉及增压器,特别是一种预压增压器。
技术介绍
增压器是冲压机床的执行机构,直压式增压器是使用纯净的压缩空气作为动力源,利用增压器内大小活塞截面比及帕斯卡能源守衡原理,将气压之低压提高数十倍供应油压工作缸使用,从而达到产品成型目的。现有的增压器主要为直压式增压器,这种直压式增压器采用全程高压式行程,接气后直接冲压成型,增压出力小,且冲压动作速度较快,作业不安全。
技术实现思路
本技术是为了解决上述技术问题,提供一种预压增压器,其可将冲压操作划分为预压和增压两段动作过程,提高增压出力,降低冲压动作速度,作业安全可靠。本技术的技术解决方案是:一种预压增压器,其特殊之处在于:包括上下布置的第一连接座、第二连接座、第三连接座和第四连接座,在第一、二连接座之间设置储油罐,在第一连接座上设有通入储油罐的预压进气孔,在第二、三连接座之间设置增压缸,所述增压缸是由缸筒和设置在缸筒内且下端敞口的活塞构成,在活塞上周向布置通油孔,且在缸筒上设有与活塞的通油孔对应的进油孔,在第二连接座上设有通入增压缸上腔的增压进气孔和通入储油罐的预压油道,且在预压油道和预压进油孔之间连接预 ...
