Abstract
The present invention relates to a kind of closed frame hydraulic press, the invention aims to solve the problem of traditional hydraulic press due to the small requirement for not being able to satisfy bigger pressure of pressure using an oil cylinder generation.The object of the present invention is achieved like this:Two pistons are provided in closed frame, i.e. upper piston and lower piston, oil cylinder bottom be fixedly connected with closed frame, and piston is slidably connected with closed frame, two pistons while giving power when work, making the pressure of the invention generated is twice of traditional hydraulic press.
Description
Technical field:
The present invention relates to a kind of closed frame hydraulic presses
Background technique:
One piston of an oil cylinder is arranged in traditional hydraulic press usually in machine frame hole, and the operating pressure of press is one
The pressure of oil cylinder is not able to satisfy the requirement of the bigger pressure of needs of technique since the pressure of an oil cylinder is small.
Summary of the invention:
A kind of closed frame hydraulic press, including closed frame [1], sliding block [2], lower piston [3], upper piston [8], cylinder bottom
[12], cylinder blocks up [15], cylinder bottom [12] is fixedly connected by screw I [10] with closed frame [1], upper piston [8] and lower piston [3]
It is slidably connected with closed frame [1], lower piston [3] is fixedly connected with sliding block [2], and sliding block [2] and closed frame [1] sliding connect
It connects, cylinder blocks up [15] and is fixedly connected by screw II [16] with closed frame [1], it is characterized in that having oil-through-hole inside enclosed [1]
[14]。
What the content of present invention was realized in:
On cylinder bottom [12] be equipped with cylinder bottom sealing ring [11], cylinder block up [15] on equipped with lower piston [3] lower seal [4] with
Cylinder blocks up sealing ring [5], and lower piston [3] is equipped with lower piston upper seal [6], and upper piston [8] is equipped with upper piston seal circle [9], closes
For formula frame [1] equipped with upper piston rod sealing ring [7] and oil-through-hole [14], cylinder, which blocks up on [15], lower oil inlet [17].
Detailed description of the invention:
Fig. 1 is overall construction drawing of the invention
Fig. 2 is hydraulic schematic diagram of the invention, is had in figure overflow valve [18], motor [19], hydraulic pump [20], check valve [21],
Hydralic pressure gauge [22], 3-position 4-way magnetic slide valve [23].F1, F2 are the left and right electromagnet of 3-position 4-way magnetic slide valve [25] respectively.
The present invention installs lower piston [3] below upper piston [8], and two pistons work simultaneously during the work time, so
The conventional hydraulic machine of only one piston of pressure ratio doubles.
Specific embodiment
To electricity, 3-position 4-way magnetic slide valve [23] is in left side working condition by motor [19] and electromagnet F2, and pressure oil is logical
The epicoele that cylinder bottom oil inlet [13] is admitted to the epicoele of upper piston [8] and is sent into lower piston [3] by oil-through-hole [14] is crossed, then
Two pistons while downlink, when lower piston [3] and sliding block [2] contact, the pressure of two pistons acts on sliding block [2] simultaneously
Sliding block [2] downlink is set to complete pressure process of the invention.When electromagnet F2 power-off and electromagnet F1 to electricity when, 3-position 4-way electromagnetism
The epicoele that slide valve [23] is in right side working condition upper piston [8] at this time leads to fuel tank, and pressure oil passes through under logical hydraulic fluid port [17] enter
The cavity of resorption of piston [3], lower piston [3] is so completed a job of the invention and is followed with upper piston [8] backhaul simultaneously at this time
Ring.
