Abstract
The utility model relates to a cylinder boosting hydraulic cylinder which is a main part on a flat die cutter. The utility model is composed of a series cylinder, a series cylinder piston, a booster rod, a hydraulic cylinder, a hydraulic cylinder piston and a controllable one-way valve. The die cutter using the utility model only uses compressed air as a power source to generate large die-cutting rules, cost is reduced, and investments are reduced.
Description
The utility model relates to a kind of flat-die die-cutting machine, belong to the light industry and machinery field.
During paper meal was produced at present, the side cut operation of cutlery box goods was to adopt mechanical crankshaft press and hydraulic pressure bead cutter, because side cut thickness has only about 1mm, thus require impulse stroke very short, and nominal pressure is also less.But present mechanical crankshaft press and hydraulic pressure bead cutter impulse stroke are all very long, incompatibility paper meal side cut operation, and structure and transmission system complexity are invested bigger.
The purpose of this utility model provides a kind of novel Hydraulic Station and motor transmission system of not needing, and is the hydraulic cylinder of power with compressed air only---the supercharge cylinders hydraulic cylinder, and as the driving mechanism of flat-die die-cutting machine.
The purpose of this utility model is achieved in that by two-stage cylinder and hydraulic cylinder to be formed.The two-stage cylinder is made up of two serial cylinders pistons and serial cylinders; The centre is divided into two sections by dividing plate; Hydraulic cylinder is made up of hydraulic cylinder and hydraulic cylinder piston and controllable check valve, hydraulic cylinder and serial cylinders coaxial arrangement, and be made of one.When compressed air entered the serial cylinders plunger shaft, piston produced thrust promotion booster rod and stretches out.The net sectional area of serial cylinders piston and booster rod is respectively A in the two-stage cylinder
1, A
2And A
3, the net sectional area of hydraulic cylinder piston is A
4, the gross area of serial cylinders piston upper chamber is A
1+ A
2, then the supercharging multiple of this system is
Promptly the gas pressure when the serial cylinders piston upper chamber is P
0The time, in-oil cylinder fluid pressure is
, by Pascal's law as can be known, the thrust of hydraulic cylinder piston rod output is
This shows, as gas pressure P
0(by compressed air unit decision) one regularly, the size of power output F is by the structures shape of this device, just by the size decision of the sectional area of serial cylinders piston, booster rod sectional area, hydraulic cylinder piston sectional area etc.
The utility model has the advantages that:
1. this device employing compressed air is power source, has reduced auxiliary equipment, has reduced cost.
2. adopt this device can obtain bigger multiplication factor, make power output reach the regulation requirement.
3. can obtain higher operating frequency, operating rate is fast.
Fig. 1 is the structural representation of supercharge cylinders hydraulic cylinder.
The utility model is described further with embodiment below in conjunction with accompanying drawing:
The supercharge cylinders hydraulic cylinder of the utility model design, by serial cylinders (1), serial cylinders piston (2), booster rod (3), hydraulic cylinder (4), hydraulic cylinder piston (5), controllable check valve (6) and on put fuel tank (7) etc. and form.
Serial cylinders (1) is made up of serial cylinders piston (2), booster rod (3), and is made of one with hydraulic cylinder (4) coaxial arrangement.At first in the plunger shaft of hydraulic cylinder (4), be full of oil, plunger shaft by pipeline and controllable check valve (6) with on put fuel tank (7) and communicate.Serial cylinders (1) is linked to each other with compressed air source by pipeline with the rod end chamber of hydraulic cylinder (4).When compressed air entered the plunger shaft of serial cylinders (1), the rod end chamber of serial cylinders (1) and hydraulic cylinder (4) communicated with atmosphere, and the gross thrust that at this moment acts on the serial cylinders piston is F=(A
1+ A
2) * P
0, then the thrust of booster rod (3) output is F=(A
1+ A
2) * P
0, because controllable check valve this moment (6) is in closed condition, the oil in the hydraulic cylinder (4) has produced pressure in the effect that is subjected to F power
The power that can be obtained acting on hydraulic cylinder (4) piston by Pascal's law is
The thrust output of hydraulic cylinder (4) piston rod is
According to the following formula result, it is suitable to select
Ratio reach the purpose of amplification power, and operating frequency is fast.The compressed air of serial cylinders (1) is imported and exported among a, b, c, the d, and a is communicated with c, and b is communicated with d, with the regular event of assurance device.Hydraulic cylinder piston (5) feeds compressed air by e when returning, and controllable check valve this moment (6) is opened, oil in the hydraulic cylinder (4) is got back to and is put fuel tank (7), b, d also feed compressed air, and a, c communicate with atmosphere, and booster rod (3) is return original position in the lump under the effect of serial cylinders piston (2).
The course of work of this device is as follows:
By on put fuel tank (7) and in hydraulic cylinder (4), inject hydraulic oil, controllable check valve (6) is closed, compressed air enters serial cylinders (2) plunger shaft by a, c, promoting booster rod (3) stretches out, sealing fluid is under the effect of booster rod (3) in the hydraulic cylinder (4), produce pressure, promote hydraulic cylinder piston (5) and stretch out.Then, controllable check valve (6) is opened, and b, d, e connect compressed air, a, c communicate with atmosphere, and under compressed-air actuated effect, hydraulic cylinder piston (5) and booster rod (3) shrink to be return, fluid in the hydraulic cylinder (4) is got back to and is put in the fuel tank (7), finishes an actuation cycle.Repeat above-mentioned action, can realize continuous operation.
Claims (1)
