Description
Technical field
The invention belongs to field of metallurgical equipment, relate to a kind of extrusion technique in aluminium extruding machine extrusion process, is a kind of aluminium extruding machine extruding room pressurizing unit and pressing method exactly.
Background technology
In conventional forward extrusion device, due to the relative motion existing between blank and extruding room inwall, extruding room has very large frictional force to blank, and this frictional force has been offset the extruding force of forward to a great extent, also makes forward extrusion have that larger pressure is remaining, contracting tail simultaneously.And reverse extrusion, pressure ram end has plug to drive extruding room and blank together to advance, and pushes and between room and blank, there is no frictional force, although do not offset extruding force, but it is slower that the metal of extruding room inwall still flows, and is prone to the draw at the afterbody of tubing extruding.
Summary of the invention
The object of the invention is to provide a kind of metal fluidity that can improve recipient inwall district in extrusion process, makes aluminium extruding machine extruding room pressurizing unit and the pressing method of the extruding room active movement that extruded product performance is improved.
The object of this invention is to provide a kind of aluminium extruding machine extruding room pressurizing unit, it is characterized in that being: at least comprise: master cylinder, main plunger, moving beam, pressure ram, extruding room that the back rest and master cylinder are made of one, push room movable cylinder, gland, checkout gear, front-axle beam, mold shaft, mould; Wherein, main plunger is in master cylinder, and main plunger outside is connected with moving beam, on moving beam, pressure ram is installed; Extruding room movable cylinder cylinder body is arranged on master cylinder, and extruding room movable cylinder plunger external part is installed on extruding room, and extruding room is concentric with pressure ram.
Described gland is between master cylinder and front-axle beam.
On described gland, checkout gear is installed, mold shaft is installed on the extruding center line of front-axle beam, and mold shaft end is provided with mould.
Checkout gear is photoelectric displacement formula speed detector.
Aluminium extruding machine extruding room pressing method, it is characterized in that: when extruding, blank extruding room in by the pressure ram of cavity both sides, mould ante-chamber arm and middle pecker compacting, in master cylinder, being filled with high pressure liquid force feed promotion pressure ram moves on, and then extrusion billet moves right by the nib of mould, make extruded product; Extruding room is driven by oil pump independently, the checkout gear being positioned on gland detects in real time to the speed of pressure ram and extruding room, according to testing result, by HYDRAULIC CONTROL SYSTEM, make the speed of pushing room remain the speed that equals or be slightly larger than pressure ram.
Extruding room produces all the time the frictional force towards mould outlet direction to blank under squeezed state, has promoted flowing of close extruding room inwall district metal, and compression blank metal, flows to mould outlet place, mold shaft end.
Advantage of the present invention is: when the main plunger being driven by master cylinder drives pressure ram extrusion billet to move to the mold shaft direction that mould is housed, the recipient being driven separately by recipient movable cylinder synchronously travels forward, its speed keeps consistent with pressure ram or slightly exceeds, make recipient inwall produce the frictional force towards metal flow direction to blank, utilize this frictional force effectively to improve the metal fluidity in recipient inwall district in extrusion process, extruded product performance is improved.
brief description of the drawings
Below in conjunction with example figure, the invention will be further described.
Fig. 1 is the front view of embodiment of the present invention structural representation;
Recipient partial enlarged drawing when Fig. 2 is Fig. 1 extrusion process.
In figure, 1. punch block mechanism; 2. master cylinder; 3. main plunger; 4. extruding room movable cylinder; 5. moving beam; 6. extruding room; 7. pressure ram; 8. gland; 9. checkout gear; 10. mold shaft; 11. front-axle beams; 12. blanks; 13. peckers; 14. moulds; 15. extruded products.
Detailed description of the invention
As depicted in figs. 1 and 2, a Novel extrusion device that pushes room active movement, at least comprises: master cylinder 2, main plunger 3, moving beam 5, pressure ram 7, extruding room 6, extruding room movable cylinder 4, gland 8, checkout gear 9, front-axle beam 11, mold shaft 10, mould 14 that the back rest and master cylinder are made of one; Wherein, main plunger 3 is in master cylinder 2, and main plunger 3 outsides are connected with moving beam 5, on moving beam 5, pressure ram 7 is installed; Extruding room movable cylinder 4 cylinder bodies are arranged on master cylinder 2, and extruding room movable cylinder 4 plunger external parts are installed on extruding room 6, and extruding room 6 is concentric with pressure ram 7.
Gland 8 is between master cylinder 2 and front-axle beam 11.
Checkout gear 9 is installed on gland 8, and mold shaft 10 is installed on the extruding center line of front-axle beam 11, and mold shaft 10 ends are provided with mould 14.
When extrusion process carries out, blank 12 is interior by the pressure ram 7 of cavity both sides, mould 14 ante-chamber arms and 13 compactings of middle pecker at extruding room 6, in master cylinder 2, being filled with high pressure liquid force feed promotion pressure ram 7 moves on, and then extrusion billet 12 moves right by the nib of mould 14, make extruded product 15.
And when pressure ram 7 advances, extruding room 6 initiatively advances by independently oil pump driving is synchronous.
