Description
Technical field
The invention belongs to aluminium and aluminium alloy and oppositely push the extrusion equipment of usefulness, particularly seamless aluminium tubing double-action reverse aluminum pressurizing unit and method.
Background technology
In existing aluminium extruding machine, the method for forward extrusion is adopted in the extruding of seamless aluminium tubing and aluminium bar material mostly, and the seamless aluminium tubing material that squeezes out causes yield rate low because there is very long macrostructure the rear end.
Summary of the invention
The purpose of this invention is to provide a kind of reverse aluminum pressing method,, improve the mechanical performance of seamless aluminium tubing material so that eliminate the defective of forward extrusion seamless aluminium tubing.
Technical scheme of the present invention is: double-action reverse aluminum and aluminum alloy extrusion device, it is characterized in that: left end has left extruder frame on slide rail, right-hand member has right extruder frame, and the extruder master cylinder is fixed on the left extruder frame, and mobile formwork is fixed on the right extruder frame; The extruder master cylinder connects left extrusion axis, and mobile formwork connects right extrusion axis, and right extrusion axis front end connects mould; Recipient is socketed on the left extrusion axis, and recipient connects the driving oil pump.
Main scissors is arranged on the described recipient.
The double-action reverse aluminum pressing method, recipient is moved to the left and overlaps to left extrusion axis by driving oil pump, the aluminium ingot base is delivered to the extruding centre bit by feeding mechanical hand, and the extruder master cylinder drives left extrusion axis and moves right, and the aluminium ingot base is pressed between mould and the left extrusion axis, recipient moves right afterwards, the driving oil pump of recipient drives recipient and is enclosed within the aluminium ingot base, and left extrusion axis and right extrusion axis clamping aluminium ingot base form hollow, and the aluminium ingot base is entangled, in this process, feeding mechanical hand withdraws from fast; After recipient moves into place, left side extrusion axis advances to jumping-up, pecker is after advancing on the mould mouth under the driving of perforation oil cylinder, the pressurization of extruder master cylinder, the aluminium ingot base begins crimp, flow out from the right by the slit between mould and the pecker,, become seamless aluminium tubing via right extrusion axis (mold shaft) and the discharging of extruder front-axle beam.
After the discharging of described extruder front-axle beam, the main scissors that is installed on the recipient is sheared defective material.
When described extruder master cylinder pressurizeed, recipient was relative with the aluminium ingot base motionless.
Characteristics of the present invention are: because left end has left extruder frame 3 on slide rail, right-hand member has right extruder frame 3, and extruder master cylinder 1 is fixed on left extruder frame 3, on the mobile formwork 11 fixing right extruder frames 3; Extruder master cylinder 1 connects left extrusion axis 4, and mobile formwork 11 connects right extrusion axis 10, and right extrusion axis 10 front ends connect mould 7; Recipient 9 is socketed on the left extrusion axis 4, and recipient 9 connects the driving oil pump.Can eliminate the defective of forward extrusion seamless aluminium tubing, improve the mechanical performance of seamless aluminium tubing material.
Description of drawings
The present invention will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, extruder master cylinder; 2, perforation oil cylinder; 3, extruder frame; 4, left extrusion axis; 5, pecker; 6, aluminium ingot base; 7, mould; 8, main scissors; 9, recipient; 10, right extrusion axis; 11, mobile formwork.
The specific embodiment
As shown in Figure 1, left end has left extruder frame 3 on slide rail, and right-hand member has right extruder frame 3, and extruder master cylinder 1 is fixed on the left extruder frame 3, on the mobile formwork 11 fixing right extruder frames 3; Extruder master cylinder 1 connects left extrusion axis 4, and mobile formwork 11 connects right extrusion axis 10 (mold shaft), and right extrusion axis 10 front ends connect mould 7; During the work beginning, recipient 9 is socketed on the left extrusion axis 4, and recipient 9 has the driving oil pump; During work, recipient 9 is moved to the left and overlaps to left extrusion axis 4 by driving oil pump, aluminium ingot base 6 is delivered to the extruding centre bit by feeding mechanical hand, extruder master cylinder 1 drives left extrusion axis 4 and moves right, aluminium ingot base 6 is pressed between mould 7 and the left extrusion axis 4, recipient 9 moves right afterwards, the driving oil pump of recipient 9 drives recipient 9 and is enclosed within aluminium ingot base 6, left side extrusion axis 4 and right extrusion axis 10 clamping aluminium ingot bases 6 form hollow, the aluminium ingot base is entangled, in this process, feeding mechanical hand withdraws from fast.After recipient 9 moves into place, left side extrusion axis 4 advances to jumping-up, pecker 5 is after advancing on 7 mouthfuls on the mould under the driving of perforation oil cylinder 2,1 pressurization of extruder master cylinder, the 5 beginning crimps of aluminium ingot base, flow out from the right by the slit between mould 7 and the pecker 5,, become seamless aluminium tubing via right extrusion axis 10 (mold shaft) and the discharging of extruder front-axle beam; After extruding finished, the main scissors 8 that is installed on the recipient 9 was sheared defective material, finishes an extrusion process.Because in extrusion process, recipient 9 is relative motionless with aluminium ingot base 6, zerofriction force between recipient 9 and the aluminium ingot base 6 becomes reverse extrusion process.
