Abstract
The invention relates to nonferrous metal continuous extrusion forming equipment, in particular to cooling systems of continuous extrusion equipment and a cooling method thereof. The two cooling systems are connected to the continuous extrusion equipment; one cooling system is for a back area of a cavity plug of a continuous extrusion mold; and the other cooling system is for a cavity outlet of the extrusion mold. The cooling system for the back of the cavity plug of the continuous extrusion mold effectively decreases the temperature of the back area, which comprises the temperature of the plug and the temperature of an extrusion wheel. The cooling system for the cavity outlet of the continuous extrusion mold directly leads a cooling medium in a discharge port of the mold for uniformly spraying around a product, so that the temperature of the extrusion mold can be lowered, and the temperature of an extruded material is decreased to the normal temperature so as to prevent the oxidation. The cooling equipment is simple in structure, preferably cools the mold through timely uniform cooling, guarantees the strength and hardness of the mold during extrusion, and prolongs the service life of the mold. Cooling water circulates to take away heat in a boot base so as to guarantee stable operation of the equipment.
Description
Technical field
The present invention relates to non-ferrous metal plastic forming field, particularly non-ferrous metal continuously extruding and molding equipment.
Background technology
Continuous squeezing method is that the bar blank of cold conditions (as up-drawing method oxygen-free copper bar) is directly sent into continuous extruder, raw material bar base is subject to radial compression and friction in holddown groove, under huge extruding and frictional force, raw material produce certain temperature rise and reach recrystallization state, extrude and one-shot forming via cavity from the mould of speciality.Just because of produced very high temperature rise in extrusion process, while especially pushing high duty metal or metal alloy, owing to being extruded, metal deformation resistance is high, caloric value is large, makes squeegee roller, material blocking block and mould need to bear higher temperature.Therefore must carry out water-cooled to the core component for extruder.In traditional continuous extruder, squeegee roller water-cooled can take to carry out in squeegee roller inside the mode of water-cooled, or carries out water-cooled at the non-trench region of the side roller outer surface on squeegee roller side, also has the outer interior cold-peace cold water-cooling pattern mutually combining.Cooling to material blocking block, patent CN101623712, by liquid medium, directly carries out cooling to squeegee roller and material blocking block.Patent CN 101934299 adopts the atomization type of cooling, has also realized and has carried out cooling to squeegee roller and material blocking block.But no matter be interior cold or external cooling method, cooling medium is far away apart from extrusion die, can cause mold temperature to be difficult to be reduced in the temperature range that conventional mold materials can bear as H13 steel, and then the destruction that causes extrusion die, make extrusion process be difficult to continue, especially cavity plug region is the position that extrusion process temperature and pressure are the highest, and this region is the cooling dead angle of frock always, is difficult to obtain effective cooling.To cavity mold, too far away apart from cooling medium, substantially can not get effectively cooling.
Summary of the invention
For the deficiency of traditional continuous extruder cooling technology, cooling means and the cooling device of mould in a kind of continuous extrusion apparatus are provided, make continuous extrusion apparatus in the time of worked copper alloy or large interface copper products, can take away in time the heat producing because of distortion, reduce the temperature of warp tool, particularly effective cooling is played in cavity plug region and cavity mold, thereby extend the service life of extrusion die, enhance productivity and production control cost.
The technical scheme that the present invention adopted is for achieving the above object: on continuous extrusion apparatus, connect two line cooling systems, a road is for the cooling system at die for continuously extruding cavity plug back, and a road is for the cooling system in extrusion die cavity exit.
Described die for continuously extruding cavity plug cooling system is by die for continuously extruding cavity plug dorsal area is carried out, without oily anhydrous blast injection, effectively reducing the temperature of cavity body of mould plug dorsal area and squeegee roller groove.
The cooling system of described die for continuously extruding cavity plug, compressed air pressure scope used is at 0.4-0.6MPa.
The cooling system of described die for continuously extruding cavity plug, is connected to ball valve on compressed air pipe used.
The cooling system of described die for continuously extruding cavity plug, its using method is closes compression Air ball valve in the time of just start, in the time that extruded stock length arrives 8-10m, slowly opens ball valve to half-open position, maintains 30min; Then adjust ball valve opening amount until maximum.
Described continuous extrusion die cavity outlet cooling system, is by design, and cooling medium is directly introduced to mould discharging mouth, evenly sprays in product surrounding.
The cooling system of described continuous extrusion die cavity outlet, cooling medium is water or ethanol water.
The cooling system of described continuous extrusion die cavity outlet, cooling medium inlet temperature range is 20 to 50 DEG C.
The cooling system of described continuous extrusion die cavity outlet, enters on boots seat cooling water pipe and is connected to ball valve.
The cooling system of described continuous extrusion die cavity outlet, its using method is: in the time of just start, close ball valve; In the time that extruded stock length reaches 8 to 10m, slowly open ball valve to 1/2 opening, maintain 30min; Then progressively adjust ball valve opening amount until maximum.
The beneficial effect of the technical program can obtain by above-mentioned description: by evenly cooling in time, product surface quality and torsional deformation improve; Mouth spray, near die for continuously extruding cavity, obtains mould well cooling, and intensity and hardness while having ensured mould extruding, improved die life.Cooling water circulation is taken away heat in boots seat, reduces the thermal deformation of boots seat and frock, has ensured equipment stable operation.By cavity plug back pressure-air cooling, effectively reduce the temperature in this region, improve working strength and the service life of plug; Make to push simultaneously race also obtain cooling in time, avoid high temperature make race part metals premature aging lost efficacy.Extruding flash also obtains cooling in time indirectly, reduces flash degree of oxidation, melts down rear minimizing bar material oxygen content.
