Description of drawings
Fig. 1 is the schematic block diagram of the step of manufacturing flow process of car load master cast cubing door module of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
Fig. 1 is the schematic block diagram of the step of manufacturing flow process of car load master cast cubing door module of the present invention.
With reference to Fig. 1, the manufacture method of car load master cast cubing door module of the present invention mainly comprises following step:
Step a: the aluminium alloy blank is carried out roughing, form the rough-wrought product of the workpiece of forming car load master cast cubing door module, and the rough-wrought product of above-mentioned workpiece is carried out Ageing Treatment.So-called roughing is exactly on the basis that keeps certain allowance, process according in advance design primary structure on the aluminium alloy blank with the CNC machining center in advance workpiece, and process the platform structure that being used to of needing in the subsequent step locate, support, lift accordingly, what need explanation here is that the platform structure that is used for locating, support, lifting is not exist at final product, but only be for the follow-up easy to process and intermediate structure of design, removal that can be in good time in follow-up procedure of processing.
As preferred version, the workpiece of the composition car load master cast cubing door module in of the present invention comprises door skin and car internal hilar plate.Below do not have specified otherwise, the workpiece of indication all describes as embodiment with door skin and car internal hilar plate.
In addition, below to the processing of workpiece, be meant and use the CNC machining center the processing that hockets of the tow sides of workpiece.
As a kind of preferred version, roughing and Ageing Treatment among the step a hocket at twice, carry out for the first time double-edged roughing, 5 millimeters surpluses are respectively stayed on the two sides, carried out natural aging treatment then 168 hours, carry out the double-edged roughing second time after the natural aging treatment, 3 millimeters surpluses are respectively stayed on the two sides, carry out artificial aging then and handle; Carry out in the roughing at the tow sides to the aluminium alloy blank, tow sides are all reserved the position of machining benchmark platform, and in addition, the locating platform that is used to lift and support also will be reserved.Described machining benchmark platform is meant the platform of the lathe tool processing dead-center position that is used for definite CNC machining center, and described locating platform is to be used for the follow-up man-hour that adds, in order not influence the structure of workpiece itself, some is suitable for the sufficient platform structure of surplus that stressed part processes at workpiece.
Artificial aging among the step a adopts following technical scheme: in temperature is that insulation was placed 6-10 hour in 180 degrees centigrade of (± 5 degrees centigrade) aging furnaces.
Step b: the corresponding machining benchmark platform of trimming on the rough-wrought product of workpiece.Because during the artificial aging in step a is handled, because the stress that roughing produces obtains discharging, and then processing deformation makes moderate progress, and the machining benchmark platform of processing among the step a may change, and therefore needs the corresponding machining benchmark platform of trimming.
Step c: the rough-wrought product to workpiece carries out semifinishing, and the control processing capacity keeps certain allowance, forms the semifinishing product of workpiece.So-called semifinishing is meant and further reduces allowance on rough machined basis, still keeps such as intermediate structures such as locating platforms simultaneously.
As a kind of preferred version, during semifinishing, the locating platform that is used to lift and support continues to keep, and controls the processing capacity of every cutter during processing in carrying out step c, and tow sides all keep 1 millimeter surplus.
Steps d: the semifinishing product to workpiece carries out Ageing Treatment.
As a kind of preferred version, the Ageing Treatment in the steps d is the natrual ageing in thermostatic chamber, and the time of natrual ageing is 72 hours, and the temperature range of thermostatic chamber temperature is 20 to 25 degrees centigrade, and as a kind of preferred version, temperature can be selected 22 degrees centigrade.
Step e: the semifinishing product to workpiece carries out the intensely processed products that fine finishining forms workpiece, and keeps certain allowance.
As preferred version, in step e, carry out the preceding machining benchmark platform finishing of fine finishining earlier, remove again and be used to the locating platform that lifts and support, carry out fine finishining, when carrying out fine finishining, remove the machining benchmark platform machining benchmark is transformed on the measuring basis hole that workpiece design itself has, control processing capacity, finally keep 0.3 millimeter surplus.
Herein, why carry out again the machining benchmark platform is revised, its reason as hereinbefore, promptly Zhi Qian step has been carried out Ageing Treatment, variation has taken place in the machining benchmark platform, in order to guarantee the accurately machined precision among the step e, so repair the machining benchmark platform again.
Step f: profile and machining benchmark platform to the intensely processed products of workpiece utilize three coordinate measuring machine (Coordinate Measuring Machining is abbreviated as CMM) to measure.
Step g: according to the concrete condition of the measurement result among the step f, carry out secondary fine finishining, profile is met the requirements, form the workpiece of required composition car load master cast cubing door module.
Allowance and intermediate structure are promptly no longer preserved in so-called secondary fine finishining, directly are machined to profile according to designing requirement.
In step g, if it is even to detect surplus among the step f, then the wherein one side of the semifinishing product of workpiece is carried out being refined to second time desired profile, no longer keep surplus and be used to the locating platform that lifts and support; For adding, reverse side still has the part that can support or lift man-hour, replace locating platform at the above-mentioned original position adhering resin material that is used to the locating platform that lifts and support that has been removed, the resin material of bonding is processed made it identical with the machining benchmark level.If it is inhomogeneous to detect surplus among the step f, then according to concrete error condition, 0.3 millimeter the surplus biasing allowance that utilizes reverse side to reserve carries out adequate compensation, carries out secondary fine finishining again.
After finishing final secondary fine finishining, remove the resin material that replaces locating platform, finish workpiece and finally process, form final products.Promptly meet door skin and inner plate of car door that precision and hardness require as previously mentioned.
Step h: assemble the workpiece of above-mentioned composition car load master cast cubing door module, form car load master cast cubing door module.
The workpiece that is about to final molding in the step g is assembled into whole car owner's model cubing door module, particularly is exactly that door skin and inner plate of car door assembling are become unified car load master cast cubing door module with regard to aforesaid preferred version, finishes whole manufacturing process.
In addition, as preferred version, the material that the aluminium alloy blank uses is that the material that workpiece uses is 6 series alloys materials.6 series alloys materials draw intensity can reach 265 MPas (Mpa), and the aluminium alloy tensile strength of technology use before has only 205 MPas (Mpa).
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
