Abstract
The utility model discloses an automatic air pressure adjusting device, which comprises an air storage tank, and an inlet pipe, an exhaust pipe, an air supply pipe and a pressure sensor arranged on the air storage tank, wherein a reversing valve and a check valve are arranged on the inlet pipe; a reversing valve is arranged on the exhaust pipe; and the two inversing valves and the pressure sensor are controlled by a host control system. The host control system of the utility model can conveniently change the internal pressure of the air storage tank in an electric control manner in the use process of a press by monitoring the air pressure in the air storage tank in real time and controlling the air suction and the exhaust of the air storage tank according to the air pressure, thus achieving setting of different tonnages for a balancer or an air cushion and achieving real-time monitoring of the air pressure.
Description
(1) technical field
The utility model relates to a kind of punching machine Pneumatic controller, particularly a kind of air pressure automatic regulating apparatus.
(2) background technology
In the course of work of punching machine, the balancer balanced capacity is different equilibrant force to be set according to concrete patrix weight, the air cushion tonnage is also because need be provided with different air cushion power according to the requirement of Sheet Metal Forming Technology, so the air pressure of its compressed air reservoir needs often to regulate.General employing is on the air inlet pipeline of air accumulator pressure-reducing valve to be installed at present, realize by manual adjustment of press operation personnel, though this method is simple, cheap, obviously can not adapt to of the requirement of large-scale stamping line to aspects such as increasingly automated, high efficiency and monitoring in real time.
(3) summary of the invention
In order to overcome the limitation that air accumulator air pressure is manually adjusted, the utility model provides a kind of air pressure automatic regulating apparatus, makes its air pressure that can realize compressed air reservoir control automatically and regulate.
In order to solve the problems of the technologies described above, the utility model comprises air accumulator, described air accumulator is provided with air inlet pipeline, gas exhaust piping, aspirating pipeline and pressure sensor, air inlet pipeline is provided with reversal valve and ball-and-seat, gas exhaust piping is provided with reversal valve, and two reversal valves and pressure sensor are controlled by engine control system.
In order to control conveniently, described two reversal valves are 2/2-way gas circuit reversal valve.
Described air inlet pipeline is provided with oil sprayer, and the effect of its oil sprayer is for the gas circuit reversal valve provides lubricated, thereby improves the condition of work of gas circuit reversal valve, prolongs its life-span.
The beneficial effects of the utility model are, the utility model engine control system is controlled the air inlet and the exhaust of air accumulator by real-time monitoring air accumulator air pressure, according to air pressure, in the forcing press use, can change the internal pressure of air accumulator very easily by the mode of electrical control, realize the setting of the different tonnages of balancer or air cushion, and can accomplish real-time monitoring air pressure.
(4) description of drawings
Fig. 1 is this practical new construction schematic diagram;
Among the figure: 1, oil sprayer, 2, reversal valve, 3, reversal valve, 4, check valve, 5, air accumulator, 6, air cushion, 7, pressure sensor.
(5) specific embodiment
A kind of specific embodiment as shown in Figure 1, comprise air accumulator 5, described air accumulator 5 is provided with air inlet pipeline, gas exhaust piping, aspirating pipeline and pressure sensor 7, be provided with oil sprayer 1, reversal valve 2 and ball-and-seat 4 from the air inlet mouth of pipe successively to air accumulator 5 on the air inlet pipeline, gas exhaust piping is provided with reversal valve 3, two reversal valves 2,3 are 2/2-way gas circuit reversal valve, and two reversal valves 2,3 and pressure sensor 7 are by engine control system control, and aspirating pipeline inserts air cushion 6 or balancer.
From the compressed air of workshop primary air pipeline, enter air accumulator 5 through oil sprayer 1, reversal valve 2, check valve 4, and provide compressed air for air cushion 6 or balancer by air accumulator 5.
When needs improved air accumulator 5 pressure, reversal valve 2 energisings were connected, and were that air accumulator 5 replenishes high pressure air by air inlet pipeline.
When needs reduced air accumulator 5 pressure, reversal valve 3 energisings were connected, and reach the step-down purpose by the discharging of air accumulator 5 compressed airs.
The effect of pressure sensor 7 is to monitor the internal pressure of air accumulator 5 in real time and electric signal is sent to engine control system, is moved by specifically controlling two 2/2-way gas circuit reversal valve switchings respectively by engine control system.
