Abstract

PURPOSE:To rationalize the manufacturing process of a sun visor and heighten its durability, by using an upper and a lower dies to press a pair of thermoplastic board materials containing a frame, to mold and fuse-bond the board materials to each other. CONSTITUTION:The mutually facing surface layers H of a pair of upper and lower board materials 1a, 1b are molten by a heater 10. A prepared frame 2 is put on the lower board material 1b. A movable ram 6 is moved down so that both the board materials 1a, 1b containing the frame 2 is pressed by an upper and a lower dies 8, 5. As a result, the mutually facing surface layers H are fuse- bonded to each other and the frame 2 is integrally pinch-held between the upper and the lower board materials 1a, 1b. After that, the ram 6 is operated for secondary pressing to move a cutter 7 down to trim the peripheral edges of the materials 1a, 1b outside the dies 8, 5. A sun visor S1 of prescribed form is thus manufactured.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a number visor for a vehicle, and its purpose is to provide a number pipe for a vehicle that can streamline the construction of the number visor and improve its durability. The purpose of this invention is to provide a manufacturing method for the present invention.Hereinafter, a first embodiment of the present invention will be explained with reference to the drawings.

First, the number visor 8sK formed in this example will be explained according to FIGS. 1 and 2.
is a substrate made of thermoplastic metal resin foam such as polypropylene foam in polyethylene foam, and includes a ring-shaped frame 2 formed of metal wire or the like along the vicinity of its periphery. I'm here.

Reference numeral 5 designates a bearing attached to the upper right corner Kl1 of the bone frame 20, and reference numeral 4 designates an Lll-shaped mounting shaft rotatably fitted into the bearing 3.

1113 for the finishing device used in the method of this example with wire i.
Figure 0) Kshiku explains with 1, 5 is tape μ! It is fixed on the top of the 9th lower metal, and the 1iK on top is no problem.
A recess 5a corresponding to am04'li is formed.

6. Can be moved up and down above the Hiro tape μT. It is.

8 Hiroshita gold xsso Opposed to the inner surface of the cutting blade 7, there is a round metal waterfall attached to the inner surface of the cutting blade 7 through the tongue body 9, and below it, there is a round gold metal waterfall on the half surface of the sun visor 81. Corresponding recess 8
m is formed.

The ninth heater 10 melts the surface of the molded object 13 before layering, and is placed horizontally so that it can be moved in and out of the upper and lower molds 118.5.Next, the above-mentioned Shiku1i! In order to explain how to mold the case Tenpaizu-81 using the lid device, first, let's look at the external shape of Tenpaizu-81.
The plate material 1alb is then held horizontally by a support frame (not shown) and moved to the lower metal 1115 and the upper movement position KTo.
At the same time, the heater 10 is inserted between both base composite materials 1aib, and both base material IL
1bO opposing surface layers H, H are melted (see Figure 3 (a))
・Next, when the heater 1o is removed from between the two substrate materials 1atIb, the nine-bone rod 2 prepared in advance is inserted into the lower substrate material 1b.
After placing it on top (see Figure 3 (b)), move the movable base 6 downward and pressurize both substrate materials 1m and 1b containing the bone frame 2 with the upper and lower metal fittings j18.5! (See Figure 113 (c)).

When this pressurized state is continued for a predetermined period of time, both substrate materials 1a and 1b are heated to a 118°50!
The part 8at5aPiK is in the #4-gre9 state and is formed under pressure, and the opposing surface layers H and III are attached to each other and integrated, and - the bone frame 2 is in the #4-gre9 state.
The integral Fc is clamped at 1bK, and on the other hand, the peripheral edge of both base composite materials 1alb is flattened by pressing the upper surface of the lower metal cover 5 and the rfJK under the stopper mso.

That firefly, Itsu9w body at Machikendai 602 next Gres! O
The cutting blade 7 is moved downward against the bullet hole to cut the periphery of the Ozeki board material 1as11sO that protrudes outside the upper and lower metal layers 8, 5, and then the movable table 6 is moved upward to form a predetermined shape and remove the 9 from the visor s1. can be obtained.

In addition, the mounting shaft 4 was replaced with the bearing 3 of the bone frame 2 after the construction of Tenbazu-81.

The operation and effects of the Odate 1 embodiment constructed as described above will now be explained.

Now, in this example, when molding a t-ton visor #violet, a pair of upper and lower substrate materials 1a*1bo and opposing surface layer
l! At the same time, attach the bone frame 2 using both substrate materials 1&, 1b.
It is possible to omit the adhesive application step in the rounded form in which the board materials are integrally sandwiched together, and the adhesive application process is omitted, and the board 1 can be firmly integrated through the welding interface, and different constituent materials can be laminated. In order to eliminate deformation over time that occurs due to uneven expansion/contraction behavior, the substrate 1 can be formed by integrally welding both the substrate materials 1m, 1b and the frame frame 2. It has the advantage that the durability performance of the sun visor 81 can be improved by significantly enhancing the reinforcing effect of the frame 2 against the sun visor 81.

Next, the second embodiment of the present invention will be explained with reference to FIGS. 4 and 5.
As shown in Fig. 114, the front and back surfaces of the substrate 1m containing the bone frame 2m are covered with an outer skin 13 made of cloth, synthetic resin film, etc.
m, 13b are shown in Table *-g.

When molding Nanvibe-81, the upper and lower metal chicks 8mm and 5mm are made of upper board material 1c and lower board material 1d.
and the upper board material 14! A torn heater 10mm to 1mm is inserted into the upper part, between the upper substrate material 1c and the lower substrate material 14, and the lower part of the lower substrate material 1d, and the upper and lower surfaces H' to H of the upper and lower substrate materials 1eeld are inserted.
' respectively #1 melt 1115 (see Fig. 0)), then k-/10jt, ial, while the upper substrate material 1
Insert the upper outer skin material 15a above aO, and insert the lower outer skin material 15b above the lower board material 110, and place the upper 1iK frame 2m on the lower board material 1a (first step). 5
(see figure)), when pressurized with upper and lower gold 118mm and 5mm, the upper and lower substrate materials 1, 14 can be welded and molded as one piece, and the lower substrate materials 1, 14 can be bonded and stopped. There is a hole that clamps the upper part of the body in one piece (see Figure JllI5 (c)).

Note that the functions and effects of the second embodiment are almost the same as those of the first Yoshikoji example, and the rounding and 70@mei are omitted.

That is, in the present invention, after melting the opposing surface layers of a pair of opposing substrate materials made of thermodustable synthetic resin,
A bone frame is inserted into the connection between the two board materials, and the edges thereof, enclosing the bone frame, and the round board materials are pressurized at the top and bottom o*m to weld them together to form a visor. Additionally, the manufacturing process for the visor can be streamlined.

By strengthening the integrated structure of the substrate and frame that make up the Tempizer, the durability of the Tenpipe can be significantly improved.This is an extremely excellent invention as a method of manufacturing Tenbaizu for vehicles.
