When making the stair web, may further comprise the steps:

1. see Figure 14, adopt the blanket 5 by density board machine-shaping, the shape of the die cavity that the shape of blanket 5 forms during with above-mentioned patrix 1 and counterdie 2 matched moulds is corresponding, and the size of blanket 5 is corresponding with the size of mould.The length of blanket 5 is 2400mm.Blanket 5 is by consisting of by fixing upper substrate 51 and the lower body 52 of white glue with vinyl bonding.

Upper substrate 51 comprises that the cross section that sets gradually from left to right that is connected as a single entity is the extension 51-3 that the 51-1 of round end section of quadrant shape (also namely 90 degree fan-shaped), main part 51-2 that cross sectional shape is rectangle substantially and cross sectional shape are rectangle.The central angle of the 51-1 of round end section is 90 °, and radius is 12mm.The soffit of main part 51-2 and extension 51-3 at grade, main part 51-2 is than being 1.5mm in thick 1mm to the 3mm(present embodiment of extension 51-3, the length of the main part 51-2 among Figure 14 and the upward and downward of extension 51-3), the right side, top of the upper surface of main part 51-2 and the 51-1 of round end section is tangent.The upper right corner of main part 51-2 is compacting or cuts into the corner subsidence part 51-4 of fillet, and the radius of described fillet is 0.5mm to 10mm, and the length of corner subsidence part 51-4 upward and downward is 1.5mm, about the subsidence part 51-4 of corner to length be 1.95mm.The upper surface of main part 51-2 and corner subsidence part 51-4 are in smoothing junction.

Lower body 52 comprises that the cross section that is positioned at the left side that is connected as a single entity is that the 52-1 of round end section of quadrant shape and the cross sectional shape that is positioned at the right side are the extension 52-2 of rectangle, and the central angle of the 52-1 of round end section is 90 °, and radius is 12mm.The right side, below of the soffit of extension 52-2 and the 52-1 of round end section is tangent, about extension 52-2 to length be 8mm, increase according to actual needs or reduce.

The upper surface of lower body 52 is fixing from below and upper substrate 51 soffits bonding, with upper substrate 51 with lower body 52 with reference to round end section separately align again both are bonded and fixed at after, after linking to each other with the 52-1 of round end section of lower body 52, the 51-1 of round end section of upper substrate 51 forms complete continuous semicircle cylinder, and as the round end of blanket 5, the soffit of the extension 52-2 of lower body 52 is parallel with the upper surface of the main part 51-2 of upper substrate 51, the upright plane 52-2-1 of the extension 52-2 of lower body 52 and the soffit of extension 52-2 are perpendicular, and the upper surface of the upright plane 51-3-1 of the extension 51-3 of upper substrate 51 and the main part 51-2 of upper substrate 51 is perpendicular.

Present embodiment also can be with being the above-mentioned blanket 5 with the two boards Adhesion formation of integrated blanket replacement, but the integral type blanket is to obtain by cutting away a cuboid piece an integral plate, this mode in actual use material loss is larger, and cost is higher.

See Figure 11, the soffit of the upper substrate 51 of blanket 5 is leaned against on the elastomeric element 4 of counterdie 2 towards the lower left, and each rear and front end 50mm apart from counterdie 2 of the rear and front end of blanket 5; Because the supporting role of elastomeric element 4, the soffit of the upper substrate 51 of blanket 5 contacts with the right lower quadrant on the 3rd plane 22 of counterdie 2, the angle on the 3rd plane 22 of the soffit of upper substrate 51 and counterdie 2 is 15 °, thereby the acute angle ψ of the angle of the soffit of upper substrate 51 and horizontal plane is 45 °.The lower body 52 of blanket 5 is positioned at the upper right side of the head portion breach 21 of counterdie 2.The upright plane 51-3-1 of the extension 51-3 of upper substrate 51 contacts with the top of the second side 23 of counterdie 2, and the upper plane of the upper substrate 51 of blanket 5 is towards the upper right side.

Consider the weight of blanket 4 and the angle that blanket 5 need to be ejected, we can change the quantity of the position of quantity, mounting groove of mounting groove or spring or select the spring of varying strength or above-mentioned two kinds, two or more means share: behind the spring of selected a kind of intensity, can control the quantity of mounting groove 25, more mounting groove 25 is set placing spring providing larger elastic force supporting blanket 5, thereby blanket 5 can be ejected larger angle; And when not needing to eject blanket 5 than wide-angle, the quantity that reduces the spring of placing gets final product; When the quantity of mounting groove 25 and position have been determined, change different flexible springs to satisfy the support requirement to blanket.

2. see Figure 12, on the upper plane of the upper substrate 51 of blanket 5, place successively gum dipped paper 61a and abrasion-proof paper 62a, and so that the lower end abutment of gum dipped paper 61a and abrasion-proof paper 62a on the plane up and right side wall that stop breach 24 of counterdie 2; Wherein gum dipped paper 61a and abrasion-proof paper 62a's is big or small identical, gum dipped paper 61a and abrasion-proof paper 62a are referred to as decorative paper 6a, the gum dipped paper 61a that adopts in the present embodiment is the facing paper through resin-dipping, and various patterns can be printed in the facing paper surface, and described resin is melmac; Abrasion-proof paper 62a forms through the melmac dipping for the surperficial or inner wear-resisting body paper of having the cloth alundum (Al2O3).Used gum dipped paper 61a is that the article number that bold and unconstrained ornament materials Co., Ltd produces in the Changzhou is the woodgrained paper of H68168 in the present embodiment, and used abrasion-proof paper 62a is that every weight per square meter that bold and unconstrained ornament materials Co., Ltd produces in the Changzhou is the abrasion-proof paper of 33g.

Abrasion-proof paper 62a covers on the gum dipped paper 61a, and the bond length of gum dipped paper 61a equals or be slightly larger than the bond length sum of the soffit of the arc length of the 52-1 of round end section of the arc length of bond length, the 51-1 of round end section on upper plane of arc length, main part 51-2 of corner subsidence part 51-4 of upper substrate 51 of blanket 5 and lower body 52 and extension 52-2.

Above-mentioned gum dipped paper 61a and these two pieces of paper of abrasion-proof paper 62a also can be replaced by a spray drawing, described spray drawing has also played wear-resisting effect when playing decoration function, therefore the article number that also can produce with bold and unconstrained ornament materials Co., Ltd in the Changzhou of present embodiment be the spray drawing of H2232 as decorative paper 6a, overlay on the upper plane 72-1 and corner subsidence part 72-3 of outer peripheral face, main part 72 of the head 71 that covers substrate 7.

3. start press, make counterdie 2 upwards liftings, matched moulds is then hot-forming.Blanket 5, gum dipped paper 61a and abrasion-proof paper 62a form in the right side area of the section of overlaying 32 that is introduced into spring clip mould 3 behind the idiosome in company with the rising of counterdie 2, this moment gum dipped paper 61a and abrasion-proof paper 62a position, left side pressurized paste section 32 active force and to the round end bending of the blanket 5 that is positioned at the right side.Along with the further rising of blanket 5, the cavity surface of the section of the overlaying 32 contact counterdies 2 of spring clip mould 3; Counterdie 2 continues to rise, and idiosome enters in the die cavity of patrix 1, and the section of the overlaying 32 also soffit along the semi-cylinder surface of the round end of blanket 5 to the lower body 52 of blanket 5 is moved.

See Fig. 3, when putting in place to patrix 1 and counterdie 2 matched moulds, the part of blanket 5 fits tightly by the die cavity section 31 of decorative paper 6a and spring clip mould 3 and the section of overlaying 32 that has fitted tightly on counterdie 2, the remainder of the outer surface of blanket 4 directly and the 3rd plane 22 of counterdie 2 and the second side 23 of counterdie 2 fit tightly; Wherein: be in the first arc lamellar body 31-1 of spring clip mould 3 and the section of the overlaying 32 formed claddings with the extension 52-2 of the round end of the blanket 5 of decorative paper 6a and lower body 52 and also mutually fit tightly; The upper plane of the main part 51-2 of upper substrate 51 fits tightly mutually with the appropriate section of decorative paper 6a and the side plane section 31-2 of spring clip mould 3; The corner subsidence part 51-4 of blanket 5 fits tightly mutually with the appropriate section of decorative paper 6a and the second arc lamellar body 31-3 of spring clip mould 3; The part that is not covered by lower body 52 of the upper substrate 51 of blanket 5 fits tightly mutually with the 3rd plane 22 of counterdie 2; The second side 23 of the upright plane 51-3-1 of the extension 51-3 of the upper substrate 51 of blanket 5 and counterdie 2 fits tightly mutually.

Although the die cavity that forms when above-mentioned patrix 1 and counterdie 2 matched moulds and blanket 4 coincide, and formally add the size that spring clip mould 3 setting in man-hour has reduced die cavity, in theory so that the profile of blanket 4 greater than the size of die cavity; But because the blanket 4 of processing is by density board machine-shaping, has slight plasticity, and spring clip mould 3 0.5 millimeters thick only, almost can ignore, when therefore counterdie 2 made progress the lifting matched moulds, under external force, negligible slight compressive strain occured in blanket 4, still can in the mold cavity that comprises spring clip mould 3, hot pressing overlay, overlay effect and reach instructions for use fully.

In addition, the ending section 33 of spring clip mould 3 stops in the breach 24 that at counterdie 2 the unnecessary part of the bottom righthand side of gum dipped paper 61a and abrasion-proof paper 62a also is positioned at and stops breach 24 during matched moulds.Stop that breach 24 has also played gum dipped paper 61a and abrasion-proof paper 62a positioning action, prevents that it is to right-hand slip when 2. step places gum dipped paper 61a and abrasion-proof paper 62a.

Because the ending section 33 of spring clip mould 3 is level and smooth small round corners with the second arc lamellar body 31-3 connecting place of die cavity section 31, so counterdie 2 bottom righthand side that upwards can not occur patrix 1 during lifting cuts off the situation that the corner subsidence part 51-4 of decorative paper 6a so that blanket 5 can not be capped; The section 33 because if spring clip mould 3 does not finish up, the second arcwall face 13 connecting places of the right-hand member soffit of patrix 1 and mold cavity are equivalent to a sharp edge of a knife, when counterdie 2 upwards is raised to decorative paper 6a near the second arcwall face 13 connecting place of the right-hand member soffit of patrix 1 and mold cavity, decorative paper 6a is very easily cut off by connecting place, in case the words of cutting off, the bond length of paper is inadequate, and the corner subsidence part 51-4 of blanket 5 just can not be capped.
