Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention relates to a method for bending and pressing a decorative board made of stainless steel or the like to a base material such as a table, a bay window of a sink, or a department store counter. This relates to press machines.

(Prior art) Conventionally, for example, as shown in FIG. 11, in order to join a stainless steel decorative board P to a base material F of a bay window H, two strips were first placed on the surface of the flat base material F to be bent. Grooves m are formed parallel to each other, a decorative board P is joined to the back side of the base material F, and the ends thereof are nailed with an automatic nailer (not shown) to connect them, and the other end of the base material F, In other words, the side on which the groove m is provided is bent halfway by hand around the groove m as shown in FIG.
After placing the base material F on the support rail 62 at the lower end and clamping it with the clamp cylinder 64, the bending press body 63 is rotated to bend the base material F together with the decorative board P, and finally, the decorative board P is attached to the base material F. were fixed by nailing with an automatic nailer.

(Problems to be Solved by the Invention) However, since the conventional press machine requires a manual bending process, not only is the work efficiency low, but also the accuracy of adhering the decorative board is reduced due to manual work. There was a problem.

In addition, when joining the decorative laminate P to the surface of the base material F whose end face has an arc shape as shown in FIG. 13, the decorative laminate P is manually bent and pressed using a press machine as shown in FIG. The decorative board P was gripped and connected to the base material F using an automatic nailer, but this method also has the same drawbacks as those described above.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention includes: a table mounted on the upper part of a machine base on which a material to be bent is placed; and a material to be bent placed on the upper surface of the table. a clamp mechanism that presses and holds the material in a predetermined position; a pair of left and right elevating frames that are attached to side frames fixed on both left and right sides of the machine base so that their positions can be adjusted in the vertical direction by an elevating mechanism; and the elevating frame bodies. a pair of left and right rotation support shafts rotatably supported by a rotation mechanism; a bending press body that is installed on both rotation support shafts and bends a material to be bent placed on the table; It is composed of:

The decorative board P is bent in the same direction around the other groove m, and the base material F and the decorative board P are rotated 90 degrees around the groove m. , Therefore, the base material F is inverted 180 degrees with the groove m as a boundary, and is pressed and bonded with an adhesive (not shown). In this state, the decorative board P and base material F are connected by nailing with an automatic nailer.

As described above, the bending press working of the material W to be bent is completed.

In addition, using the press machine of the above example, the 13th
As shown in the figure, in order to bend and press the decorative board P on the round end surface of the base material F, the bending press body 4
4 may be rotated 180 degrees at once, but at this time, the lifting cylinder 13 is operated at the same time to hold the bending press body 44 at an appropriate height position.

Note that the present invention can also be embodied as follows.

A measuring mechanism (not shown) for measuring the thickness of the material to be bent W is provided, and the upper limit setting mechanism 26 of the lifting frame 12 can be automatically switched and adjusted based on the numerical value measured by this measuring mechanism. shall be configured.
