Background technology
" acrylic " is a phonemic loans, and English is ACRYLIC, also known as " acrylic ".It is a kind of chemical material.Chemistry
Name is called " PMMA " category polyacrylate, " by the lucite of specially treated " is commonly called as, in the original of application industry acrylic
Material is general to be occurred in forms such as particle, sheet material, tubing.Acrylic, also known as the lucite of specially treated, is that lucite is changed
For product, the lamp box made of acrylic have good light transmission, pure color, rich color, it is attractive in appearance it is smooth, take into account night on daytime
Evening two kinds of effects, long service lifes, the features such as using is not influenceed, additionally, acryl plates and plastic-aluminum profile material, senior screen printing
Etc. the demand that with perfect adaptation, can meet businessman, acrylic plastic uptake is to improve business StoreFront class, and unified corporate image is best
Outdoor advertising form.Acrylic board is plane plate body, for product structure the need for, it usually needs by the face of acrylic board
Plate carries out bending process, is made into the acrylic board of curved face type, when bending process are carried out, it usually needs first counter plate
Heated at curved surface so that soften at curved surface, after then panel is bent, the cooling and shaping on platform.And in cooling
During sizing, if plate body is directly erected to cool down, the curvature portion of plate body is susceptible to collapse, and destroys the moulding knot of plate body
Structure；If the curvature portion of plate body is fitted in curved surface groove being shaped, because plate body is larger with curved surface groove contact area so that
Cooling effectiveness is significantly relatively low, and producing efficiency is not high.
The content of the invention
It is an object of the invention to provide a kind of reasonable in design, curved slab body-shaping effect is good, and cooling effectiveness is high, side
Just making, the method for shaping and its shaping equipment for curved surface acrylic board of sizing different size curved slab, above-mentioned to solve
The problem proposed in background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of method for shaping for curved surface acrylic board, method for shaping step is as follows：

The side of gram force plate two carries out clamping, after placement, is tentatively shaped, and preliminary shaping time is 2~4min；
D, cooling
The acrylic plate of preliminary sizing is taken out together with press plate mechanism, then, the curved face part of acrylic plate is placed upward
Placement cooling is carried out on the table, after cooling is finished, is got product.
A kind of shaping equipment for curved surface acrylic board, including workbench and shaping mechanism, on the workbench left side
Square installation settings has shaping mechanism, and the shaping mechanism includes shaped block, offered in the shaped block and curved surface acrylic board
The arc groove of cooperation, the arc groove is made up of the tapered plane of middle arcwall face and both sides, matches somebody with somebody in the arc groove
Conjunction is provided with press plate mechanism, and the press plate mechanism includes one group of pressing article be arrangeding in parallel and at least two connecting rods, the pressure
It is fixedly connected by connecting rod between lath, the connecting rod is the flexible body of rod, is provided with for fixing lock on connecting rod outer wall
The clamping screw of tight length, connecting rod outer wall is alongst provided with length scale line.
As further scheme of the invention：The workbench is mounted in frame.
As further scheme of the invention：The pressing article top is provided with horizontal pressing plate top surface, pressing article bottom
It is provided with the pressing plate inclined-plane for coordinating with the tapered plane of arc groove and contacting.
As further scheme of the invention：The pressing plate chamfered inside is offered matches somebody with somebody with curved surface acrylic board side
The pressing plate draw-in groove of conjunction.
As further scheme of the invention：The cushion fitted with curved surface acrylic board is equipped with the arc groove
Layer.
Compared with prior art, the beneficial effects of the invention are as follows：Plate body is placed on shaped block by plate body by after thermal softening
In arc groove, the side of plate body two is overlayed into conjunction by the pressing article of press plate mechanism is carried out tentatively on the tapered plane of arc groove
Cooling, has been effectively ensured the modeling structure of plate body, it is to avoid curvature portion is collapsed；After the completion of preliminary cooling, by plate body and pressure
Trigger structure is together taken out, and the pressing plate top surface of pressing article is fitted with workbench, and plate body curved surface is set upward, and the side of plate body two is still
It is assemblied in the pressing plate draw-in groove on pressing plate inclined-plane, because plate body inwall has been carried out preliminary cooling, therefore plate body in shaped block
Curved surface will not be collapsed again, so as to accelerate the quick cooling and shaping of plate body outer wall, substantially increase cooling effectiveness；Due to pressing plate
It is fixedly connected by the flexible body of rod between bar, therefore, it can the distance between regulation pressing article, so that convenient makes, shapes not
The curved slab of same specification size；After the completion of the regulation of the distance between pressing article, by screwing clamping screw, you can ensure pressing article
The distance between keep stabilization, can understand that to read the distance between pressing article big by the length scale line on connecting rod outer wall
Small, width adjusting is easy to operate, and size is held accurate.Reasonable in design of the present invention, curved slab body-shaping effect is good, cooling effect
Rate is high, convenient making, the curved slab of sizing different specification size.
