Description

A kind of four corner pressure regulating device of upper hydraulic cushion on hydraulic machine
Technical field
The utility model belongs to the hydraulic press technical field, particularly relates to a kind of four corner pressure regulating device of upper hydraulic cushion on hydraulic machine.
Background technology
At present, along with the continuous development of science and technology, people are also improving constantly the requirement of hydraulic press, wish also can realize the irregular workpiece of complexity is carried out functions such as pre-binder, dnockout on general hydralic stamping press, want to realize these functions so, must regulate the pressure of hydraulic die cushion.Existing technology can't be carried out four jiaos by required pressure regulation, causes the binder difficulty, the percent defective height, and the hydraulic problems that can't satisfy production demand, particularly special workpiece is more outstanding.
Summary of the invention
The utility model provides a kind of four corner pressure regulating device of upper hydraulic cushion on hydraulic machine for solving the technical problem that exists in the known technology.
The purpose of this utility model provides that a kind of to have simple in structure, convenient, reliable and stable a, complete function of control, function admirable, operating cost low, is easy to realize the four corner pressure regulating device of upper hydraulic cushion on hydraulic machine of the characteristics such as compression moulding of complex part.
The utility model realizes that upward the control of four jiaos of pressure regulation of hydraulic die cushion is on four corner pistons cylinders of last hydraulic die cushion an independently hydraulic control system to be set.In the control system, last hydraulic die cushion cylinder participates in the binder technological action, is to overlap independently mini system; When last hydraulic die cushion cylinder is realized the dnockout technological action, be another set of independently mini system.By controlling the break-make of different magnetic valves, can select hydraulic die cushion whether to participate in work.The binder pressure of hydraulic die cushion is gone up in proportional pressure control valve control, by selecting the corresponding proportional pressure control valve of each hydraulic cylinder, controls the pressure of itself.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of four corner pressure regulating device of upper hydraulic cushion on hydraulic machine comprises conduit under fluid pressure and magnetic valve, it is characterized in that: the four corner pressure regulating device of upper hydraulic cushion on hydraulic machine is to go up hydraulic die cushion four corner pistons cylinders are set, and each piston cylinder is provided with an independently hydraulic control; Hydraulic control is independently controlled the hydraulic die cushion piston cylinder and is carried out binder and dnockout technological action.
The utility model can also adopt following technical scheme:
The four corner pressure regulating device of described upper hydraulic cushion on hydraulic machine is characterized in: hydraulic control is respectively the independently dnockout controlling organization that independently binder controlling organization that proportional pressure control valve and check valve connect and compose and inserted valve group constitute.
The four corner pressure regulating device of described upper hydraulic cushion on hydraulic machine is characterized in: hydraulic control is provided with Programmable Logic Controller and pressure sensor, and Programmable Logic Controller connects control ratio overflow valve, inserted valve group and pressure sensor.
Advantage and the good effect that the utlity model has are:
The four corner pressure regulating device of upper hydraulic cushion on hydraulic machine is owing to adopted the utility model brand-new technology scheme, compared with prior art, the utility model is applied in proportional pressure control valve on the hydraulic press can effectively regulate liquid working pressure, its control is stable, reliably, and after being applied in this technology on the hydraulic press, can make the type hydraulic press have stretching, crooked, in the time of technologies such as moulding, also has binder, functions such as dnockout, make the function of press more comprehensive, performance is more good, while is according to the profile difference of processing work, regulate four jiaos of pressure participations of hydraulic die cushion work of going up arbitrarily, reduce the operating cost of processing, be easy to realize the compression moulding of complex part.So this technology has highly application value.
Description of drawings
Fig. 1 is the four corner pressure regulating device hydraulic principle structural representation of the utility model upper hydraulic cushion on hydraulic machine.
Among the figure, the last hydraulic die cushion of 1-, the last hydraulic die cushion cylinder of 2-, 3-pressure measuring tie-in, 4-pressure sensor, 5-proportional pressure control valve, 6-check valve, 7-Pressure gauge, 8-inserted valve group, 9-manual pressure regulating valve, 10-oil pipe.
The specific embodiment
For further understanding technology contents of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Consult accompanying drawing 1.
Embodiment 1
A kind of four corner pressure regulating device of upper hydraulic cushion on hydraulic machine comprises conduit under fluid pressure and magnetic valve, it is characterized in that: the four corner pressure regulating device of upper hydraulic cushion on hydraulic machine is to go up hydraulic die cushion four corner pistons cylinders are set, and each piston cylinder is provided with an independently hydraulic control; Hydraulic control is independently controlled the hydraulic die cushion piston cylinder and is carried out binder and dnockout technological action.
Hydraulic control is respectively the independently dnockout controlling organization that independently binder controlling organization that proportional pressure control valve and check valve connect and compose and inserted valve group constitute.Hydraulic control is provided with Programmable Logic Controller and pressure sensor, and Programmable Logic Controller connects control ratio overflow valve, inserted valve group and pressure sensor.
The concrete course of work of present embodiment:
When upper hydraulic cushion on hydraulic machine is realized binder technology, go up hydraulic die cushion when starting working and be in lower dead point position, it is descending that the slide block band hydraulic die cushion, when running into workpiece, last hydraulic die cushion begins passive binder, proportional pressure control valve 5YAA, YAB, YAC, the binder pressure of hydraulic die cushion 1 is gone up in YAD and check valve 6 controls, pressure measuring tie-in 3 can record the pressure of hydraulic die cushion cylinder 2, pressure sensor 4BP1, BP2, BP3, what BP4 detected is the binder pressure of the last hydraulic die cushion 1 in the work, the data that record are fed back among the PLC, conversion process by data, be presented on the control box, the handled easily person reads and is provided with running parameter; When last hydraulic die cushion is realized dnockout technology, it is descending that electromagnet YA51, YA53 get electric last hydraulic die cushion in the inserted valve group 8, and inserted valve group 8 is connected oil pipes 10, and manual pressure regulating valve 9 is regulated the dnockout pressure, Pressure gauge 7 shows the dnockout pressure, and electromagnet YA52, YA54 get the electric hydraulic die cushion of going up and return in the inserted valve group 8.
