With reference to all accompanying drawings, in Fig. 1, be expressed as the dull and stereotyped A of gypsum and the B in cross section, before it is clamped between the former portion C of shaping press and the formpiston part D, accompany the ply of board 1 and 3 of gypsum plate 2 respectively by the centre, and middle ply of board 4 and 6 formation that accompany gypsum plate 5, by overlapping and compression, dull and stereotyped A of gypsum and B and vinyl glue or other suitable water base cementing agent extend in ply of board 3 or 4, that is, in the contact surface of connected two flat boards, extend.
Extending by flooding treated ply of board and it being become, their bendings are convenient in then such extension, and the gypsum plate 2 and 5 that is rigidity stands continuous radially cracking, according to bend radius, the thickness of described gypsum plate, and poor between the outermost of each sheet and inner periphery thereafter, they are more or less closely at interval.
In water base evaporation and adhesive cures in the needed time, continue always pressurization two arcs with overlapping dull and stereotyped A and B, thereby the stable formation press bending of being forced for good and all.This process be because: in each connected two gypsum flat board, gypsum plate radially ftractures, and the ply of board on the arc outside extends, and the compression of the ply of board on the inboard.Therefore, the bonding of the ply of board 3 of dull and stereotyped A and the ply of board 4 of dull and stereotyped B forces both to reach the permanent stable balance of relative separately crooked tension force, that is, and and the stretched tension of the shrink tension of ply of board 3 and ply of board 4.
By on bonded surface, pasting and the band of hot-melt adhesive or the band or the bar of the water base vinyl cementing agent that bar replaces, then the retention time of the paired arc flat board in shaping press can shorten significantly, thereby the time of speed production, described hot-melt adhesive is the urea resin in the aqueous solution for example, and it gets faster than vinyl adhesive cures.
Fig. 3 and 4 illustrates, if the curvature of giving by means of the former part F and the formpiston part G of moulding press especially significantly or obviously, then crooked simultaneously and bond dull and stereotyped A and B, after surface 3 and 4 is applied suitable cementing agent, laterally disposed abreast with its extension, and in the process in it is inserted in shaping press, adopt a flexible sheet metal E, it is placed on the outside of arc to be formed, in specific example, it contacts with the ply of board 6 of dull and stereotyped B, guarantees the bending that all plates are perfect, and the radially cracking in gypsum plate 2 and 5 distributes basically uniformly.
