Description
Technical field
The invention belongs to field of metallurgical equipment, relate to a kind of extrusion technique in the aluminium extruding machine extrusion process, is a kind of aluminium extruding machine extruding room pressurizing unit and pressing method exactly.
Background technology
In the conventional forward extrusion device, because the relative motion that exists between blank and the extruding room inwall, the 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, and also larger pressure is remaining, the contracting tail so that forward extrusion exists simultaneously.And reverse extrusion, the pressure ram end has plug to drive the extruding room and blank together advances, and does not have the existence of frictional force between extruding room and the blank, although do not offset extruding force, but it is slower that the metal of extruding room inwall still flows, and the afterbody that pushes at tubing is prone to the draw.
Summary of the invention
The object of the invention provides a kind of metal fluidity that can improve recipient inwall district in the extrusion process, makes aluminium extruding machine extruding room pressurizing unit and the pressing method of the extruding room active movement that the extruded product performance is improved.
The purpose of this invention is to provide a kind of aluminium extruding machine extruding room pressurizing unit, it is characterized in that being: comprise at least: master cylinder, main plunger, moving beam, pressure ram, the 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 the main plunger outside is connected with moving beam, on the moving beam pressure ram is installed; Extruding room movable cylinder cylinder body is installed on the master cylinder, and extruding room movable cylinder plunger external part is installed on the extruding room, and the extruding room is concentric with pressure ram.
Described gland is between master cylinder and front-axle beam.
On the described gland checkout gear is installed, mold shaft is installed on the extruding center line of front-axle beam, and the mold shaft end is equipped with mould.
Checkout gear is photoelectric displacement formula speed detector.
Aluminium extruding machine extruding room pressing method, it is characterized in that: during extruding, blank the extruding room in by the pressure ram of cavity both sides, mould ante-chamber arm and middle pecker compacting, being filled with high pressure liquid force feed promotion pressure ram in the master cylinder moves on, and then the nib of extrusion billet by mould move right, and makes extruded product; The extruding room is by independently oil pump driving, the checkout gear that is positioned on the gland detects in real time to the speed of pressure ram with the extruding room, according to testing result, by HYDRAULIC CONTROL SYSTEM, so that the speed of extruding room remains the speed that equals or be slightly larger than pressure ram.
The extruding room produces frictional force towards the mould outlet direction all the time to blank under squeezed state, 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: the main plunger that is driven by master cylinder drives the pressure ram extrusion billet when the mold shaft direction motion of mould is housed, the recipient that is driven separately by the recipient movable cylinder travels forward synchronously, its speed keeps consistent with pressure ram or slightly exceeds, so that the recipient inwall is to the frictional force of blank generation towards the metal flow direction, utilize this frictional force effectively to improve the metal fluidity in recipient inwall district in the extrusion process, the extruded product performance is improved.
Description of drawings
The invention will be further described below in conjunction with example figure.

Recipient partial enlarged drawing when Fig. 2 is Fig. 1 extrusion process.
Among the figure, 1. punch block mechanism; 2. master cylinder; 3. main plunger; 4. push the room movable cylinder; 5. move beam; 6. extruding room; 7. pressure ram; 8. gland; 9. checkout gear; 10. mold shaft; 11. front-axle beam; 12. blank; 13. pecker; 14. mould; 15. extruded product.
The specific embodiment
As depicted in figs. 1 and 2, a kind of Novel extrusion device that pushes the room active movement comprises at least: 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 the moving beam 5 pressure ram 7 is installed; Extruding room movable cylinder 4 cylinder bodies are installed on the master cylinder 2, and extruding room movable cylinder 4 plunger external parts are installed on the extruding room 6, and extruding room 6 is concentric with pressure ram 7.
Checkout gear 9 is installed on the gland 8, and mold shaft 10 is installed on the extruding center line of front-axle beam 11, and mold shaft 10 ends are equipped 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, being filled with high pressure liquid force feed promotion pressure ram 7 in the master cylinder 2 moves on, and then the nib of extrusion billet 12 by mould 14 move right, and makes extruded product 15.
And when pressure ram 7 advanced, extruding room 6 initiatively advanced by independently the oil pump driving is synchronous.
