Abstract
A shell of amplifier and its manufacturing process, in order to solve the low cost, the anti-combustion performance is good, the qualification rate is high, the product and technological process with little work load, the invention uses the aluminium alloy as the product material, replace the multiple processing procedure by improving the mould shaping degree, finish combining a small amount of subsequent processing, in this way, can improve the performance of the product, reduce the technological difficulty, reduce the work load.
Description
Technical field
The present invention relates to a kind of housing and manufacturing process thereof of amplifier housing, especially amplifier.
Background technology
Present amplifier all is thin, the rectangle closed-in construction of wall, restricts can not rely in the requirement of environment for use to improve wall thickness and enhance product performance.And case material is to adopt the magnesium alloy casting in conjunction with machine work, and its shortcoming is that production process control is complicated, and allowance is big, product percent of pass is not high, final according to statistics qualification rate can make waste of material serious only at 30-50% like this, brings long objective requirement of production cycle simultaneously; And the material cost height, easy firing.At process aspect is to adopt casting and following process to finish, and overall structures is that wall is thin, the rectangular frame structure, and the size instability after the processing causes workload big, inefficiency like this.
Summary of the invention
This shows that we need design low cost of manufacture, the flame resistant performance is good, qualification rate height, product that workload is little and technological process.
The present invention adopts aluminium alloy as product material, replaces multi-step process by improving the mould molding degree, finishes 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 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.
Adopt aluminium alloy as product material, can enhance product performance, and moulding technology can reduce workload, improve product percent of pass.
Embodiment
In design and concrete manufacture process, we can adopt special die casting and manufacturing process.
One, extrusion process
We come properties of product by improving mold design, and following two kinds of schemes are arranged:
1, inner chamber adopts the oblique top plate, inner chamber is divided into several, successively the demoulding; External form is loosed core with Four-slider and two.Can solve the difficult problem that inner chamber does not have draw taper like this.
2, inner chamber adopts overall structure; Feed solutions is for adopting trumpet assembly, multipoint mode charging all around, twice parting.Mirror finish that so just can be by adopting core surface and select for use rational release agent can allow inner chamber as far as possible reduce draw taper has solved the problem of the no draw taper of inner chamber; While trumpet assembly, the multipoint mode charging can improve the flowability of molten metal, realizes the difficulty of the difficult moulding of thin-wall product, and product cooling rate basically identical has guaranteed that organizing of product is more even in addition, has reduced deformation extent in follow-up adding.
Two, manufacturing process
A, maximum draw taper: length A=89 (calculating), the chi of concentric reducer with 0.5 monolateral allowance
Very little poor B=0.1 (that is: dimensional tolerance is 0.1).
α＝tg
-1((0.1/2)/90)＝0.032deg

Annotate: S
X: the stroke of slide block
S
Y: the core of slide block is deviate from the displacement 15 of shaping place fully
K: be coefficient of safety (getting 2mm)
Because 2S
XBe the spacing 44 between 34≤stagger angle, so the pit at stagger angle place can adopt the mode of slide block to be shaped.
C, put the allowance position: cylindrical is put 1.8mm, and both ends of the surface respectively put 0.5.
The making of d, mould and debugging:
In mold core processing, adopt the import silk cutting machine tool of being careful, inner chamber precision and the requirement of whose surfaces roughness are guaranteed in the time processing moulding, simultaneously to die casting system color center multipoint mode feeding structure, the color twice parting design of ejecting mechanism.Adopt powerful release agent in addition, can avoid product to pull and improve fineness.
Claims (5)
1. the housing of an amplifier and manufacturing process thereof is characterized in that adopting aluminium alloy as product material, replace multi-step process by improving the mould molding degree, finish in conjunction with a small amount of following process.
2. according to claim 1, it is characterized in that inner chamber adopts the oblique top plate, is divided into several with inner chamber, successively the demoulding.
3. according to claim 1, it is characterized in that external form looses core with Four-slider and two.
