Abstract

PURPOSE:To miniaturize the titled apparatus, and to improve the work efficiency, by providing a punching member, etc., and constituting so that lock seaming of a small projecting piece part provided in a joining hole of a panel can be interlocked by one motion. CONSTITUTION:A titled device consists of a link mechanism 12 having a pair of punching members 18, 19 for bending small projecting parts a2, a3 which are left so as to be mutually opposed to joining holes a1, b1 of panels (a), (b), a link driving means 13 for operating this mechanism 12, and a base driving means 1 by which a base 6 for placing this means 13 is made to execute a reciprocating motion. Said panels (a), (b) are overlapped by matching the joining holes a1, b1, are set on a work receiver 24, and thereafter, by tip parts 18a, 19a of the punching members 18, 19, the small projecting piece parts a2, a3 are pushed into the other hole b1 and are bent, and are raised by 90 deg.. Subsequently, the panels (a), (b) are pressed against a clamping member (c), in front of a bracket 20, are further bent by 180 deg., and the panels (a), (b) are joined.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seam-folding device for joining two panels by overlapping nine joining holes of the same shape and size, and joining two panels by seam-folding.

The conventional seam folding method is to connect the two panels with the #1 holes of the same shape and size, and then insert the seam fold reference hole made in the joint hole of one panel. Two devices are required: a device that inserts the panel into the other joining hole at an angle of 90 degrees, and a device that bends the first folded seam portion outward by a further 90 degrees and joins both panels together. I blamed it.

However, in such a conventional seam folding method, a device that raises the seam folding part by 90 degrees, and a 90f,
In other words, since the equipment for bending into 1801i1 was separate, the equipment as a whole became larger, and there were problems in that not only did it require a large space for peace of mind, but it was also inefficient due to the need for double-layer work. Ta.

This invention was made by focusing on these conventional problems, and allows the first 90-degree bending of the seam and the subsequent bending to 180 tL to be performed continuously with one device. An embodiment of the present invention, which solves the above problems, will be described below with reference to the drawings.

First, to describe the structure, l is a base driving cylinder of a driving means fixed to the rear end of the pedestal 2 and rotatable by a pin 4 on the support metal fitting 3; The base 6 is reciprocated via a toggle mechanism 1 which is rotatably woven with a pin 5 and connected to the rear end of the base 6. In addition, the base 6 is erected on the pedestal 2 with nine pillars 8.9
are equipped with 91 pairs of guide rollers 10. It is held in a reciprocating manner by the lI, and a link drive cylinder 8, which is a drive means for operating the link mechanism 12, is mounted on the rear half. As shown in detail in FIG. 3, the link mechanism 12tf includes a pair of upper and lower intermediate links 16 and 17, each of which has one end attached to the clevis 15 attached to the piston rod of the link drive cylinder 18. Punch members 1B and 19 each having a rounded plane are sandwiched and connected to the end portions, and the punch members I8.19 have tip portions 18a and 19a having a P-shaped plane, and cross each other. It is rotatably attached to a bracket 20 erected at the end of the base 6 by means of fixed poles 21 and 22.

In front of the workpiece (referred to as work) W, two pieces of flannel a
, bFi, as shown in Fig. 4 1 (b), the joining holes aI and bI of the same shape and size are overlapped, and the clamping member C of the jig (see Fig. #!1←)) The front strut 8 is aligned with the folding hole hK drilled at the required location.
The clamp member CK is crimped and held by a work receiver 24 provided at the upper end of a moving surface metal fitting 23 fixed to the clamp member CK. In addition, small projecting pieces a-2 and a3 are left so as to face each other in the joining hole alKt'i of panel a (see Fig. 4).
.

Next, the effect will be described.

After setting the panel a1b to the clamping member C of the jig as described above (FIG. 4, 1(a)), the base driving cylinder (2) is operated to move the base 6 to the guide roller 1 via the toggle mechanism 1.
G, l If you move it forward along IK, from Figure 4 1 to 4
As seen in Figure IK, the punch member 1B in the closed state,
19, the tip part 188% 19a pushes the small projecting pieces a2 and a3 into the joining hole bl, bends it to stand up 90f, and stops when the panels a and b are pressed against the clamp member C in front of the bracket 20. (Image Otori (a)). Next, as shown in FIG. 3, when the link driving cylinder I3 is activated and its piston rod 14 moves forward, the intermediate link 16,
+7 is punch member heat 8.19! Since the IkI111 is opened outward, the punch members 1g and 19 are attached to the bolts 21 and 22.
The tip rotates outward using the
198 also rotates outward, so push down the small projecting piece a2sa8 to the left and right with its P-shaped central protrusion, and further attach it to the tip surface of the bracket 20 so as to wrap the periphery of the joining hole bl together with the panel a%b. For 90f folding and pressing, use both panels a,
Join b (■ (a) in the same figure).

At the end of the connection, the link driving cylinder 181-
When the piston rod I4 is moved backward, the punch members 18 and 19 are rotated inward by the intermediate links 16 and +7, and the tips 18a and 19aVi are closed. When the base 6 is moved backward via the link mechanism 12, the tips 18a, 19a
is the bonding hole b1. The nuki comes out from al and returns to the original position,
It is biased towards the next processing.

As explained above, according to the present invention, the small projecting pieces provided in the joining holes of the panels are folded in conjunction with each other in one movement using the link mechanism. As a result, the overall amount of iron can be reduced in size, and the flap can be folded sufficiently in a narrow space, and work efficiency can be improved.Also, since it can be performed by a series of operations, it can be automated. There is also an advantage.
