Abstract
The invention relates to a fan-shaped support with a thin wall, a frame, multiple bosses and a platform structure and an aluminum alloy die-casting technology; in order to improve the textural structure and solve the product and the technological process with low cost, high qualified rate and small workload, an aluminum alloy is taken as a product material in the technology, a plurality of processing procedures are replaced by improving the shaping degree of a mold by designing a new blank and a new mold, and a small number of follow-up processing procedures are combined for completing the technology, thereby improving the product performances, reducing the technological difficulty, reducing the workload and solving the bottleneck problem in batch production.
Description
Technical field
The present invention relates to a kind of aluminum alloy die-casting technological method for fan-shaped support, especially thin-walled, framework, many boss, planar structure fan and manufacturing process thereof.
Background technology
Such fan that is assemblied on certain important equipment electrocircuit composite slab belongs to thin-walled, fan-shaped, many boss, planar structure at present, restrict harsh requirement in assembly environment, can not rely on the raising wall thickness enhances product performance, owing to thin-walled, fan-shaped, many boss, planar structure belong to asymmetric obform body, adopt very easily product thermal stress deformation of forging type simultaneously.In research and production for many years, what all adopt is that the magnesium alloy plate engraving forms, and its shortcoming is that production process control is complicated, and easy firing, allowance are big, production cycle is long, the finished product cooperative rate is low, and according to industry statistic, yield rate is at 30%-50%, not only make waste of material serious, outside the production cost height, have a strong impact on delivery date simultaneously, become such industry technology and production bottleneck; And the utilization rate about 10% of material, cost height, easy firing in the production process.Because adopt the processing method of whole magnesium alloy plate engraving, the size distortion after the processing is bigger like this, the finished size instability causes workload big, and production efficiency is extremely low.
Summary of the invention
For this reason, we need design low cost of manufacture, and the flame resistant performance is good, yield rate height, product that the machined workload is little and technological process.
The technical solution adopted for the present invention to solve the technical problems is: adopt aluminium alloy as product material, by design novel die and product blank, replace whole magnesium alloy plate, multi-step process with the mould molding degree, do not finish in conjunction with a small amount of following process.Aluminum alloy materials is lower than magnesium alloy materials cost, and the flame resistant performance is good, can satisfy requirements such as harsh temperatures, fusing point.We adopt the high die casting mode of moulding degree to reduce dependence to following process at process aspect, so just can improve the qualification rate of product, can reduce workload simultaneously.
Beneficial effect of the present invention is that the employing aluminium alloy can enhance product performance, and moulding technology can reduce workload as product material, improves product percent of pass.
The specific embodiment
At design aspect, we have adopted the A380 aluminium alloy to replace magnesium alloy materials, have designed new-type blank and aluminum alloy die-casting technological rules, and procedure parameter is developed, and have determined the technological feasibility of the employing new material of product.
In the concrete manufacture process, we can adopt following design:
One, special die casting and casting technique.
We improve properties of product by design novel die realization die casting new technology, adopt following scheme:
Because product belongs to thin-walled, framework, many boss structures, with traditional blank design, very easily distortion, can't adopt the die casting mode to realize, we adopt the reinforcement mode that increases at the blank design for this reason, will link to each other in twos with reinforcement between many boss, make product form solid, network structure by plane, frame structure, improve the rigidity of blank moulding, thereby realized product extrusion process route, solved the technological difficulties of this extrusion process of this series products.
Feed solutions adopts trumpet assembly, multiple feed all around.This mode can solve the flowability of improving molten metal, and the technological difficulties of the difficult moulding of implementation framework thin-wall product keep the cooling velocity unanimity of product in addition, have guaranteed that organizing of product is more even, have reduced the die casting thermal stress deformation.
Two, a spot of process for machining
At the characteristics of fan handling ease distortion, in the design process, we have adopted the little machining allowance of trying one's best, process for machining rules and frock clamp reasonable in design, thereby the distortion of avoiding machined to cause influences the finished product accuracy of fan, satisfies matching requirements.
Claims (4)
1. the fan and the extrusion process thereof of a thin-walled, framework, many boss, planar structure, it is characterized in that adopting aluminium alloy as product material, replace original magnesium alloy materials, by designing new-type blank and mould, improve the mould molding degree and replace whole magnesium alloy plate Carving Machining operation, finish in conjunction with a spot of following process.
2. according to claim 1, it is characterized in that and will link to each other in twos with reinforcement between many boss.
3. according to claim 1, it is characterized in that the blank of the fan of thin-walled, framework, many boss, planar structure is designed to thin-walled, solid, network structure.
4. according to claim 1, it is characterized in that feed solutions is to adopt trumpet assembly, multipoint mode charging all around.
