Description
Technical field
The present invention relates to underwater acrylic hemisphere manufacture technology fields, more specifically, are related to sub- gram of underwater uniform thickness
Power hemisphere production method.
Background technique
What the window of underwater equipment generallyd use at present is acrylic hemisphere, the production of current existing acrylic hemisphere
Method be usually blow or die casting.
The method of existing blowing is: by one piece of acrylic board, with an intensity by the annulus that calculates by acrylic board
It pushes down, one bulk strength of pressure is equal to the hard plectane of top pressure ring by the diameter met the requirements calculated below acrylic board, uses
Bolt or other tools are by annulus, and the plectane of acrylic and lower section is locked together, and one or more air inlets, lead among plectane
Air inlet is crossed to high-pressure hot gas is blown between acrylic layer and plectane, in this way under the action of hot gas, acrylic is heated to be softened,
Since air pressure is very high, the pressure that air pressure generates is enough to offset the tension of acrylic itself, sub- at this moment under the pressure of high pressure gas
Gram force gradually starts upward bulging, forms arc-shaped convex surface, and the sizes of air inflows and air pressure are controlled according to the difference of required shape,
When reaching required size, stop air inlet and keep air pressure, so that acrylic shape is maintained at current shape, after acrylic is cooling
Remove the plectane of pressure ring and lower section air inlet.
But above-mentioned the drawbacks of doing so is obvious, because blowing out, final arc acrylic is that have out
The one block of plate to begin is blown, so arc acrylic after molding top is the most weak place of integral thickness, and thickness
It is gradually thinning to cambered top end from annulus.In this way if expecting that top has certain thickness arc acrylic,
The acryl plates thickness for needing most to start is very big, has been far longer than the thickness of top acrylic.
The method of existing die casting: firstly the need of processing one set of die, the acrylic of required size can be formed
Mold, if it is desired to change acrylic size, then need to continue growing mold.Secondly an injection molding machine or casting machine are needed,
So that single injection or casting amount can satisfy the dosage of required acrylic.And the bubble that also control in production process is asked
Topic.The product size of die casting is more accurate, but higher cost, needs to customize the mold of size and the injection molding of large size
Or casting machine, the method higher cost of die casting.
Summary of the invention
The present invention is directed to solve at least some of the technical problems in related technologies.For this purpose, of the invention
One purpose is to propose underwater uniform thickness acrylic hemisphere production method.
The technical scheme to solve the above technical problems is that underwater uniform thickness acrylic hemisphere production method,
It includes the steps of determining that valve number required for acrylic hemisphere manufacturing process and size, determine the corresponding mold of acrylic valve
Size determines acrylic panel size, hot briquetting, splicing casting fusion seam according to acrylic valve number and die size.
The beneficial effects of the present invention are: a simple and practical method is provided to process the product of uniform thickness acrylic hemisphere,
It is all improved in terms of raw material, equipment, processing cost relative to traditional processing method, directly reduces and be processed into
This, is changed to spicing forming type for hemisphere acrylic one-pass molding, whole process is divided into several steps in this way, to make to form wind
Danger reduces, and processing cost reduces, and improves yield rate.
Based on the above technical solution, the present invention can also be improved as follows.
Further, valve number and size required for the determining acrylic hemisphere manufacturing process are specifically, determine Asia
After the thickness of gram force hemisphere, determines that the acrylic hemisphere production valve number to be divided into such as can choose and be divided into 4 valves, 6 valves, 8
Valve etc. selects suitable acryl plates, and plate thickness should be greater than the thickness equal to finished product acrylic hemisphere, according to acrylic point
At valve number and acrylic hemisphere internal diameter, plate is divided into the suitable acrylic block of size, adjacent acrylic block
Between have fusion seam.
Further, the corresponding die size of the determining acrylic valve is specifically, determine valve number that Ya Ke is divided into such as
It can choose after being divided into 4 valves, 6 valves, 8 valves etc. and the internal diameter of acrylic hemisphere, be divided into size suitable on mold
Mold block has fusion seam between mold block, and the size of general fusion seam is in 4~5mm.
Further, described that acrylic panel size is determined specifically, according to true according to acrylic valve number and die size
The size for the every valve arc acrylic determined, the size of every piece of acryl plates needed for calculating, and guarantee actually to be cut into
The size of the every piece of acryl plates come is greater than calculated board dimension.
Further, the hot briquetting has occurred specifically, the acrylic plate divided is placed in baking oven to it
Soften and do not melt, plate is taken out rapidly to the acrylic for being placed on the circular arc mold made, having softened at this time
Plate can be fitted in above arcuate die naturally under the effect of gravity, move into baking oven a period of time together for whole at this time,
So that acrylic is bonded with mold completely.The acrylic that the acrylic after waiting but has been changed to arc is taken out, it at this moment will be sub-
Gram force edge is modified and is polished according to die size, keeps arc acrylic consistent with die size.Similarly, each valve arc
Acrylic according to said method makes.
Further, the splicing casting fusion seam is specifically, the arc petaloid acrylic that will be fabricated to is fitted in advance
The smooth complete hemisphere surface in the surface made, the outer diameter of this hemisphere is identical as the internal diameter for the acrylic hemisphere to be made,
And it is uniformly distributed every valve acrylic, so that every fusion seam size is identical, is then stitched with the acrylic perfusion fusion of liquid, directly
It is full of completely by liquid acrylic to fusion seam, after liquid acrylic solidifies 48 hours in seam to be fused, and confirms that fusion has been stitched
The removable whole hemisphere acrylic spliced in all solidstate rear, stitches polishing for the fusion of surface bulge using milling tools at this time
It is equal to the curvature of acrylic valve, the acrylic hemisphere completion of processing of such a complete uniform thickness to smooth and curvature.
