It is shaped as sheet material.
Aluminum current based ceramic powder end strengthens composite and mainly uses the method for extruding metal and rolling to produce this kind of sheet material
For nuclear industry, this type of sheet material of China is substantially from imported from America, and price is extremely expensive, therefore in the urgent need to this kind
The extruding method of material.
Summary of the invention
The purpose of this utility model is to provide one can improve production efficiency and yield rate, reduces the aluminum base of production cost
Ceramic powders strengthens coextrusion apparatus.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is:
Al-base ceramic powder strengthens coextrusion apparatus, including frame and master cylinder component and mounted thereto
Pressure ram, is set with the recipient placing Al-base ceramic powder enhancing composite ingot blank on pressure ram, recipient
End is provided with on extrusion die assembly, described recipient and extrusion die assembly and is separately installed with recipient temperature control
Device processed and extrusion die temperature control equipment.
Described pressure ram end is also equipped with fixation extrusion pad.
It is as follows that this utility model Al-base ceramic powder strengthens composite pressing method: before extrusion process, first, will
Recipient and Al-base ceramic powder strengthen composite ingot blank and are heated to 500 DEG C, simultaneously by pressure ram and fixation extrusion pad
Preheat in recipient, and utilize recipient temperature control equipment to control recipient temperature at 500 ± 10 DEG C；
Secondly, extrusion die assembly 1 is heated to 550 DEG C, utilizes die temperature control device to extrusion die simultaneously
Assembly carries out temperature control so that it is temperature stabilization at 550 ± 10 DEG C,
Finally, the extrusion speed making extruder is maintained at 0.5～2mm/s to carry out extrusion process and obtains Al-base ceramic powder
Strengthen composite.
Described recipient temperature control equipment when recipient temperature is more than 510 DEG C, recipient temperature control equipment pair
Recipient carries out cooling to 500 DEG C, and when temperature is less than 490 DEG C, recipient temperature control equipment is by recipient
It is heated to 500 DEG C.
Described die temperature control device is when extrusion die assembly is more than 560 DEG C, and die temperature control device is to squeezing
Compression mould assembly carries out cooling to 550 DEG C, and when temperature is less than 540 DEG C, die temperature control device will extruding
Die assembly is heated to 550 DEG C.
Die temperature control device of the present utility model is fixed on extrusion die assembly, and die temperature control device is with crowded
Pressure cylinder temperature control equipment all has the functions such as heating, cooling and temperature detection.
Owing to Al-base ceramic powder enhancing composite is more sensitive to the change of temperature and speed in extrusion process, pass through
Test and simulation found that: when recipient temperature controls to control in the temperature of 500 ± 10 DEG C He extrusion die
Under conditions of 550 ± 10 DEG C, and keeping extrusion speed when 0.5～2mm/s, its extruding metal mobility is best, has most
Being beneficial to its extrusion process molding, when the temperature is too low, metal fluidity is deteriorated, and easily causes vexed car and product to ftracture
Phenomenon, when temperature is too high, the aluminum matrix composite that the ceramic particle owing to using strengthens, easily cause material to flow
Uneven, make extruded after organizational structure and mechanical heterogeneity and become waste product；Same extrusion speed is too fast
Or cross and the material of product all can be caused slowly uneven or the defect such as cracking.The motorisation unit utilizing extruder completes
Aluminum base strengthens composite ingot blank feeding action, and recipient lock onto die surface, utilizes the speed of extruder to regulate system
System, keeps extrusion speed to carry out extrusion process in the range of 0.5～2mm/s.
When extrusion process, due to the shadow of the factor such as frictional force of be squeezed power change and ingot blank and recipient and mould
Ringing, in extrusion process, the temperature of recipient and extrusion die can change, and controls dress now by recipient temperature
Put and respectively the temperature of recipient and extrusion die is adjusted with die temperature control device, make recipient temperature control
At 500 ± 10 DEG C, the temperature of extrusion die controls 550 ± 10 Celsius, to ensure that aluminum base strengthens composite ingot blank
The metal fluidity of extrusion process.
The aluminum base produced by this utility model strengthens the part of composite, and at material mechanical performance, material structure causes
The aspects such as close property are obviously enhanced.Produced by pressing method simultaneously and can effectively reduce production cost, and pass through mould
Tool technology, can produce complicated and diversified aluminum base and strengthen composite material parts.
