Abstract
The utility model relates to a forming pressure controller for a powder forming machine, which is composed of a slide block, a valve seat, a pressure speed changer and a control box which are connected together, wherein the slide block is fixed to the upper surface of a bottom plate through a cylinder body on the slide block; the valve seat is provided with a pressure transmitter, an oil inlet pipe and an oil outlet valve, is fixed to one side of the bottom plate, and is connected with a one-way valve of which one end is connected with the cylinder body through the valve seat, and the other end is connected with an air pressure regulating valve successively through the valve seat, the oil inlet pipe, an oil-gas converting cylinder and an air inlet pipe. By adjusting and controlling an air pressure regulator, inlet air pressure and outlet oil pressure of the oil-gas converting cylinder can keep unchanged in a certain range so as to ensure that oil pressure input to the pressure cylinder body via the oil pipe can keep stable and can not cause changes; the size of the air gap between a guide screw and a piston can not be suddenly changed and keep the stable state, and the guide screw can not seize. The controller ensures pressure stability born on pressed products in the whole pressing process, raises product qualification rate, reduces production cost and extends the service life of the powder forming machine.
Description
Technical field
The utility model relates to the vitals in the powder forming machine, and a kind of to be used for controlling stampings constant at the forming process pressure, thereby makes the stampings steady quality and the powder forming machine forming pressure controller that uses.
Background technology
Used powder forming machine, its forming pressure controller adopts the manual pump structure more, oil pressure is just used the manual operating manual pump less than operating pressure in cylinder body, increase the oil pressure in the cylinder body, if surpassing operating pressure, oil pressure then draws back the pump pressure release, supercharging that this is sudden or decompression, make the gap of screw mandrel and piston space become very little once or become very big once, if the gap can be killed when too minor leading screw is worked, job insecurity is easily rocked in its gap too big wire role, this kind controller had both influenced the crudy of product, influenced the service life of powder forming machine again.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of powder forming machine forming pressure controller is provided, be installed on the powder forming machine, make powder forming machine in the whole production pressing process, it is constant to remain pressure stability, thereby guarantee the stampings steady quality, improve the qualification rate of product, reduced production cost.
The present invention addresses the above problem the technical scheme that is adopted: powder forming machine forming pressure controller, be fixed on the upper surface of base plate by the cylinder body on it by slide block, the valve seat that pressure transmitter, oil inlet pipe, fuel outlet valve are installed is fixed on the side of base plate, pressure transmitter be connected with control cabinet form, also be connected with check valve on the described valve seat, one end of check valve is connected with cylinder body by valve seat, and end is connected with the air pressure regulator valve by valve seat, oil inlet pipe, oil gas changeover bobbin, air inlet pipe successively in addition.
Compared with prior art, advantage of the present utility model is: original pressure controller is to pressurize or reduce pressure with the manual operating manual pump, make like this enter the variation of oil pressure in the cylinder body be mutability once greatly, once little very inhomogeneous, inhomogeneous because of the pressure variation, can cause a lot of substandard products.And this pressure controller is to be regulated, controlled by air transformer, make the air pressure that enters the oil gas changeover bobbin and the oil pressure of outflow stablize constant within the specific limits, thereby guarantee through the oil pressure of oil inlet pipe input pressure cylinder body stable, can not undergo mutation, thereby the size of gaps of screw mandrel and piston space can not suddenlyd change yet, keep stable state, screw mandrel just can not killed, both guaranteed that the stampings pressure was stable in the whole pressing process, improved the qualification rate of product again, reduce production cost, and prolonged the service life of powder forming machine.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
In the cylinder body 7 in the middle of the slide block 1, being equipped with the piston 6 of band sealing ring, is hemispheric groove in the middle of the piston 6, and the positioning key 4 that two correspondences, centre have through hole is fixed in the both sides, upper surface.
The lower end of screw mandrel 2 is the middle ball petioliform that through hole is arranged, be fixed on two positioning keys 4 by bearing pin 5, and can be along the through hole on the positioning key 4, forward and backward swing in the groove in the middle of piston 6, lid 3 is screwed on the upper surface of cylinder body 7, the lower surface of cylinder body 7 is screwed on base plate 12, and the valve seat 9 that pressure transmitter 8, check valve 11, fuel outlet valve 10, oil inlet pipe 13 are installed is screwed on a side of base plate 12, as shown in Figure 1.
Screw mandrel 2 upper ends are connected with crankshaft-link rod 18 on the powder forming machine, and air pressure regulator valve 17 is installed in the Pneumatic controlled box 20, and Pneumatic controlled box 20, control cabinet 14 are installed on the frame 19 of powder forming machine, also are fixed with oil gas changeover bobbin 15 on frame 19 1 sides, as shown in Figure 3.
Gas pressure regulating valve 17 is connected with the upper end of oil gas changeover bobbin 15 by air inlet pipe 16, the lower end of oil gas changeover bobbin 15 is connected with valve seat 9 by oil inlet pipe 13, oil outlet on the valve seat is connected with fuel feed hole on the check valve 11, oil outlet on the check valve 11 is connected with valve seat, valve seat 9 is connected with cylinder body 7, pressure transmitter 8, fuel outlet valve 10, as shown in Figure 2.
During use, through adjusting, the control of air pressure regulator valve 17, the air pressure that remains its output is in 1～10 kilograms per centimeter
2In the scope, enter into gas, down in the oily oil gas changeover bobbin 15, and make the pressure oil of output in the oil gas changeover bobbin 15 also remain on 1～10 kilograms per centimeter
2Constant in the scope, can show or control from the display screen on the control cabinet on the powder forming machine 14, pressure oil is supplied with cylinder body 7 and is used through oil inlet pipe 13, check valve 11, in the process, if cylinder pressure surpasses pressing pressure, just can pass through fuel outlet valve 10 pressure releases, check valve 11 stops the high pressure oil returns in oil gas changeover bobbin 15, and it is stable to remain in the cylinder body 7 oil pressure.
