Description

The automatic harder of dry powder

Technical field

The utility model relates to a kind of automatic harder with metallurgical part base substrate of dry powder pressed powder and electrotechnical ceramics spare base substrate.

Background technology

The press that is used for metallurgical part of dry powder pressed powder and electrotechnical ceramics spare base substrate at present has two big classes: a class is the mechanical transmission-type harder, be characterized in that precision is than the high efficiency height, but pressure is all below 20 tons, the height of pressing blank is less than 20 millimeters, increase press power and pressed compact height again, the harder structure will be too huge, and cost also is very expensive.Another kind of is to utilize general hydraulic press pressed compact, and production efficiency is low, complicated operation, and the mould guiding accuracy is poor, can only suppress the product of simple shape.

Summary of the invention

For improving the base substrate height and the precision of pressed compact, strengthen press power, realize automated production, the utility model provides a kind of automatic harder of dry powder that is exclusively used in metallurgical part of dry powder pressed powder and electrotechnical ceramics spare base substrate.

The technical scheme that its technical problem that solves the utility model adopts is: at one by support, demoulding oil jar, workbench, mould bases, column, guide plate, entablature, the compacting oil cylinder, fuel feed pump, electric control box, the oil pressure station, hopper, feed appliance, feeding oil cylinder, the mould bases seat, reinforced locator, the high locator of base, on the dry powder harder that demoulding locator is formed, to suppress oil cylinder is contained on the entablature lifting simultaneously and goes into column, feeding oil cylinder is contained in the support, demoulding oil jar is packed in the centre bore of workbench, driving force adopts hydraulic technology, controls the compacting oil cylinder respectively by three solenoid directional control valves in the oil pressure station, demoulding oil jar, feeding oil cylinder work; Utilize programmable controller, gather the duty of three solenoid directional control valves of each alignment sensor data centralization control, realize that harder is reinforced, compression moulding, demoulding automatic operating; Adopt special die carrier to make and touch tool manufacturing, installation codeization, standardization, adopt the adjustable locator of mechanical type, respectively to reinforced height, pressed compact height, pressing stroke, take off and touch the position and accurately locate.

The utility model has following effect: owing to adopted hydraulic transmission power, press structure is oversimplified, the volume of machine, weight are also corresponding dwindles, and press power and pressed compact height can increase substantially, cost with compare with tonnage mechanical type press imitate have only its 1/3rd; Owing to adopted control technology able to programme, this harder can be by the programming automation work of compiling and editing; Owing to adopted special die carrier, make the mould manufacturing, the energy standardization and normalization is installed; Owing to adopted the adjustable locator of mechanical type, make this harder pressed green body size, weight, density all secure.The utility model automaticity height, reliable operation can realize that a people manages multimachine, reduces production costs significantly.
