Description

[Detailed explanation of the invention] [Field of industrial application]
Regarding a jig suitable for use in a bending mold for making bent materials such as dovetail curved outer panels, in particular, an auxiliary member that can continuously create the connecting portion between the flat part and the bent part of the bent material. The present invention relates to a jig for creating a bending pattern.

[Prior art]

Generally, when building a ship, a large number of ship skins are required, and these skins include curved skins,
It is roughly divided into three types: flat skin and curved skin with flat skin.

Here, for the bent outer panel, a mold for bending the outer panel is made using a universal jig as shown in FIG. 3, and the bending work is performed.

As shown in Fig. 3, the universal jig consists of a jig body H and a free bending member (hereinafter referred to as "buttten") attached to the jig body H via an adjustment mechanism AJ.
By adjusting the adjustment mechanism AJ, a freely curved shape can be formed on the batten 1 and its edges, thereby creating a curved mold. In addition, the adjustment mechanism AJ is
a plurality of adjustment members 2 attached to the adjustment member 2; a lock mechanism R with a thumbscrew 3 that engages with the elongated hole 2a formed in each adjustment member 2 and the hole with the jig body H to fix the adjustment member 2; Consists of.

In addition, after marking and cutting, the Hiratan skin will become the ship's skin as it is. This is an exterior panel that does not require any bending work.

Furthermore, for the curved outer panel with a flat section, a wooden pattern W as shown in FIG. 6 is manually made and bent for the outer panel.

That is, when using the wooden pattern W, first draw a full-sized curved part on the film, set the universal jig on the line of the film, and then draw the wooden pattern W.
The actual product is then bent to fit the wooden pattern.

Here, the reason why the wooden pattern W is used to make the curved outer panel with a flat section is as follows. That is,
Universal jig Batsuten 1 can handle various bends, but it can handle a straight part SP and a curved part with point P as the boundary.
This is because it cannot be applied to curves that include CP. It is sufficient if the curve matches the desired curve as shown in Fig. 4, but normally, as shown in Fig. 5, the curve formed by the desired curve and the curve 1 (this is the curved part CP1 and CP2 bordering on point P). )
It doesn't overlap. In other words, the straight part is better than the curved part CP.
When creating an SP, it is possible to construct a straight line part SP using this jig, but it is difficult for the P point to be in the drawing shape. Therefore, a wooden mold W as shown in Fig. 6 is made of wood and used as a mold for bending the outer panel.

[Problem that the invention attempts to solve]

As described above, the conventional universal jig (bending mold making jig) has the following problems because it is necessary to make a wooden pattern W, especially when making an outer panel with a flat part.

(1) It takes a lot of materials and time to manually make a wooden pattern W for curved outer panels.

(2) A large space and carpentry tools are required to make the wooden pattern W.

(3) It is necessary to transport the wooden molds for bending from the place where the wooden molds are made to the work area for bending the outer panels.

The present invention aims to solve these problems, and by adding an auxiliary member for making flat shapes, it eliminates the time and effort of making wooden molds as in the past, and allows for the creation of curved molds. It is an object of the present invention to provide a jig for making a bending mold with an auxiliary member, which can shorten the time required and reduce costs.

[Means for solving problems]

For this reason, the jig for making a bending mold with an auxiliary member of the present invention is provided with a free bending member attached to the jig body via an adjustment mechanism, and a straight edge that can be connected to a curved edge of the free bending member is provided. Auxiliary parts equipped with
It is characterized by being attached so that its position can be adjusted.

[Effect]

In the above-mentioned bending mold making jig with auxiliary members of the present invention, for example, in order to make a skin with a flat part, the free bending member is bent and adjusted according to the curved part of the skin, and the free bending member is adjusted to fit the curved part of the skin. The attachment position of the auxiliary member is adjusted so that the straight edge of the auxiliary member is connected to the curved edge of the bending member. As a result, this jig will be created as a bent mold. After that, the above-mentioned outer panel is made using the main jig set in this way.

〔Example〕

Hereinafter, a bending mold making jig with an auxiliary member as an embodiment of the present invention will be explained with reference to the drawings. FIG. 1 is a configuration diagram of its main parts, FIG. 2 is a perspective view showing its auxiliary member, In Figures 1 and 2, 3rd~
The same reference numerals as in FIG. 6 indicate almost the same parts.

As shown in Fig. 1, this jig, like the conventional one, includes a jig main body H and a batten 1 attached to the jig main body H via an adjustment mechanism AJ. By adjusting AJ,
The edge of the batten 1 can be formed into a freely curved shape.

Note that the adjustment mechanism AJ is also composed of a plurality of adjustment members 2 and a lock mechanism R with a thumbscrew 3, as in the conventional case.

By the way, as shown in Figs. 1 and 2, there is a straight edge (a part forming a straight part SP) that can be connected to a curved edge (a part forming a curved part CP) of the batten 1.
An auxiliary tool (auxiliary member) 4 is provided, and an elongated hole 4a is formed along the longitudinal direction of the auxiliary tool 4.
so that the mounting position can be adjusted with a thumbscrew 5 (this thumbscrew 5 constitutes a locking mechanism R' for attaching the auxiliary tool 4 to the adjustment member 2 in a position-adjustable manner). It's getting old.

Note that in this embodiment, two auxiliary tools 4 are used.

With the above configuration, in order to use this jig to create the desired curved shape for the outer panel with a flat section, loosen the thumbscrews 3 and adjust each adjustment member 2 so that it matches the curved shape of the outer panel. is moved up and down in FIG. 1, and when the desired curved shape is obtained, the thumbscrew 3 is tightened and fixed. In addition, the lower edge of one of the auxiliary tools 4 is set at the boundary position P between the curved part CP and the straight part SP, and the thumbscrew 5 is set so that the straight part SP and the straight edge of the auxiliary tool 4 are aligned. With the auxiliary tool 4 loosened,
It is moved left and right in the figure, and when the desired position is reached, the thumbscrew 5 is tightened and fixed.

Furthermore, the mounting position of the other auxiliary tool 4 is adjusted in the same manner so that the straight edge of the other auxiliary tool 4 is located on an extension of the straight edge of one of the auxiliary tools 4.

In this way, the desired curved shape (including straight portions) is obtained, and after that, the present jig is used as a curved shape for the outer panel with a flat butt portion.

This provides the following effects or advantages.

(1) There is no need to make a wooden mold, which saves time.
