Abstract
Disclosed is a hydraulic-drive automatic feeding system. A mold press automatic feeding system serves as an important constitution portion of the mold press, and the reasonability and the feasibility of the design guarantee the normal operation of the whole system. During mold pressing, the automatic feeding system replaces labor to complete feeding, so that the labor intensity and the labor danger coefficient are greatly reduced, and the work efficiency is greatly improved. The hydraulic system meeting particular requirements of the automatic feeding system is designed after synthesizing advantages and disadvantages at home and abroad, and scientific and rigorous calculation and analysis are performed on all parts of the system, so that the system feasibility is guaranteed theoretically. Started from the environment protection, the system oil pollution problem is analyzed, and corresponding solutions are put forward, so that the mold press is developed towards the green direction.
Description
Technical field
This product is a kind of hydraulic pressure feed system.
Background technology
In the pressing process of mould, consider the reason of labour intensity etc., should not be by manually realizing in the launch process of workpiece.Molding press certainly
moving feed system can replace and manually completes this process.Security, operating efficiency etc. improve greatly.Labour intensity reduces greatly.
Summary of the invention
The object of this invention is to provide a kind of hydraulic transmission that is best suited for feed system.
The object of the present invention is achieved like this:
Hydraulic system is mainly made up of fuel tank (1), oil filter (2), hydraulic pump (3), overflow valve (4), start-stop valve (5), choke valve (6), reversal valve (7), hydraulic cylinder (8) and oil pipe (9) piston (10), the workbench (11) that connect these elements.
Its operation principle is such:
Hydraulic drive carrys out transferring energy using liquid as working media;
Hydraulic drive carrys out transferring power with the pressure energy of liquid, and it is not identical with the hydraulic power that utilizes liquid kinetic energy;
Working media in hydraulic drive carries out work under controlled, modulated state, and therefore hydraulic drive and hydraulic control are usually difficult to well-separated.
Its operation acts process is such: hydraulic pump (3) by motor driven rotary after, oil suction from fuel tank (9).Fluid enters hydraulic pump (3) through oil filter (2), when it exports and enter after force pipe from pump, enters hydraulic cylinder (8) one chambeies by start-stop valve (5), choke valve (6), reversal valve (7), promotes piston (10) and workbench (11) motion.At this moment, the oil in another chamber of hydraulic cylinder (8) flows back to fuel tank (1) through reversal valve (7) and oil return pipe (9).
The invention has the beneficial effects as follows:
Under equal volume, hydraulic means can produce larger power than electric device, and the Comparision of hydraulic means is steady.Hydraulic means is realized stepless speed regulation in can be on a large scale, and hydraulic drive easily is automated, and controls or regulates because it is pressure, flow and flow direction to liquid, handles easily.When hydraulic control and electrical control or pneumatic control combine while using, can realize complicated sequentially-operating and Long-distance Control.Realize rectilinear motion more than simple by machine driving with hydraulic drive.

Detailed description of the invention
By be connected in series a check valve 6 in loop, thereby the in-line during by F.F. and oil return line cut off the mutual connection of in-line, oil return line while solving slide unit F.F., and problem that cannot build-up pressure, surges and change.On oil return line, be connected in series a hydraulic sequence valve 8, to stop fluid oil return line in the time that fast forward stage is returned to fuel tank and solved slide unit and advance fast to connect fuel tank, cannot realize the problem of the differential connection of hydraulic cylinder.Fluid in the time that the exit of electro-hydraulic reversing valve is set up a check valve 1 and solved that system quits work in system flows to fuel tank, causes air to enter system, affects the problem of slide unit robust motion.Must set up a pressure switch 14 at flow speed control valve output and be convenient to system and automatically send and return fast signal.The position of sequence valve 8 and counterbalance valve is exchanged, thereby the unloader at sequence valve and oil sources place is merged.
Claims (2)
1. a hydraulic-driven autoloader, it mainly comprises piston, hydraulic circuit, hydraulic pump, hydraulic cylinder, hydraulic valve, hydraulic pump provides power, and by fluid transmission pressure, hydraulic cylinder, hydraulic valves etc. carry out Artificial Control to hydraulic pressure, and pressure transmission, to piston, has piston to go to perform an action the most at last.
2. the hydraulic-driven autoloader requiring according to right 1, it is characterized in that: the power of this feed system is little, slide unit movement velocity is low, workload changes less, therefore adopt the speed governing form of inlet throttle, so the circulation of fluid must be open type in system, first from improving system effectiveness, save in the angle of energy, adopt domestic contrast maturation product---twin constant displacement pump is as oil sources, secondly select rapid movement and commutation loop, in system, adopt after throttling speed control circuit, no matter adopt any oil sources form all must have independent oil circuit directly to lead to hydraulic cylinder two chambeies, to realize rapid movement, in native system, single pole hydraulic cylinder will do differential connection, when slide unit transfer rewind down to by F.F. time, the flow passing through in loop is larger, in order to ensure the steady of commutation, adopt electro-hydraulic reversing valve formula changing-over loop, because the differential connection of hydraulic cylinder will be realized in this loop, reversal valve must be five-way, such hydraulic circuit system is very suitable for this pay-off.
