闭式框架液压机制造技术
Closed frame hydraulic press
The invention relates to a closed frame hydraulic press. The object of the invention is to solve the problem that the traditional hydraulic press has an oil cylinder which produces little pressure and can not meet the requirement of greater pressure. The purpose of the invention is: the bottom of the oil cylinder and the closed frame is fixedly connected with the piston is connected with the closed sliding frame, the piston is connected with the closed sliding frame, the piston in the cylinder piston is connected with the lower sliding block is fixedly connected with the closed frame is connected with the sliding piston. The internal piston is fixedly connected with the slide block. The upper frame is provided with an upper exhaust port, a lower exhaust port is arranged on the lower piston, and a cylinder is provided with a cylinder to block the oil inlet, and the inner cylinder is blocked with an inner cylinder to block the oil inlet. The present invention installs a lower piston under the piston, and at the same time, the two pistons act at the same time, so the total pressure is doubled as compared with the traditional hydraulic press with only one piston.

闭式框架液压机
：本专利技术涉及一种闭式框架液压机。
技术介绍
；传统的液压机通常在机架孔内设置一个油缸一个活塞，压机的工作压力只是一个油缸的压力，由于一个油缸的压力小，不能满足工艺的需要更大压力的要求。
技术实现思路
：一种闭式框架液压机，包括闭式框架[1]，滑块[2]，活塞[10]，活塞下密封圈[8]，油缸底[13]，活塞上密封圈[11]油缸底螺栓[12]油缸底[13]，油缸底进油口[14]，油缸底密封圈[15]，其特征是：闭式框架[1]内部有通油孔[16]，活塞[10]下面装有下活塞[7]，下活塞[7]内装有内活塞[3]。本
技术实现思路
是这样实现的：油缸底[13]通过油缸底螺栓[12]与闭式框架[1]固定连接，油缸底[13]上装有油缸底密封圈[15]，活塞[10]与闭式框架[1]滑动连接，下活塞[7]与闭式框架[1]滑动连接，内活塞[3]与下活塞[7]滑动连接，缸堵[21]通过缸堵螺钉[20]与闭式框架[1]固定连接，内缸堵[25]通过内缸堵螺钉[24]与下活塞[7]固定连接。内活塞[3]与滑块[2]固定连接。在缸堵[21]上装有下活塞[7]的下密封圈[5]，下...
