Description

[Detailed description of the invention] (Industrial application field) The present invention is a caulking machine used when forming a roof sheet by connecting the upper edges of folded plates formed in a V shape or a concave shape. It is related to.

(Prior art) In recent years, the roofs of station platforms, gymnasiums, factories, etc. have been formed into arbitrary shapes using folded plates as shown in Figure 5.
It is formed by connecting many M′.

Although this folded plate M' is convenient to transport, it is desired that the connecting and assembling can be performed easily and smoothly.

Thus, the inner ridge portion a′ and the outer ridge portion b′ formed at both upper ends of the folded plate M′ overlap the outer ridge portion of the adjacent folded plate M′.
b' and the inner rib part a', and the fitting recess m' is the fifth
They are connected by tightening using a tightening machine A' as shown in the figure.

This caulking machine A' includes a holder 2' having a fitting recess 5' attached to the tip of one gripping rod 1;
The gripping rod 1' has an engaging part 6' attached to the tip of the other gripping rod 1', and the engaging part 6' has a collar piece 6'a on the front side of the gripping rod 3'. It is formed to protrude.

To connect the folded plate M', the fitting recess 5 of the holder 2' is fitted into the outer rib part b' side of the fitting part m' formed by the inner rib part a' and the outer rib part b'. At the same time, the flange piece 6'a of the engagement part 6' of the clasp fastener 3' has an outer flange part.
The tip end b' ₁ of b' is engaged, and by closing the bar fastener 3' toward the holder 2', the tip b' ₁ of the outer bar b' is bent inside the inner bar a'. These are tightened and connected by being connected.

(Problems to be Solved by the Invention) However, in the above-mentioned tightening machine, since the engaging part of the locking tool is formed by a collar piece protruding from the front,
If the tip of the outer bar is engaged with the collar piece and bent, the upper end of the bar will come off from the engagement part when the bar fastener moves, making it impossible to tighten the bar easily and smoothly. There was a problem.

The present invention was made in view of the above problems, and its purpose is to provide a crimping machine that can easily and smoothly connect folded plates.

(Means for Solving the Problems) The means of the present invention for solving the above problems is to provide a fitting recess at one end of the gripping rod, which is formed to be able to open and close freely around the end. In the crimping machine, a folding plate to be crimped is attached to the engaging part of the staking tool, and a staking tool having an engaging part is attached to the other end of the staking tool. An engagement groove is provided in which the tip of the outer bezel engages, and the engagement groove is provided with an engagement groove in which the locking tool is closed toward the holder and the tip of the outer bevel is aligned with the inner surface of the fitting recess. The present invention is characterized in that it includes an inclined surface that receives the tip end surface of the tip portion when it is bent.

(Function) According to the above configuration, when connecting the folded plates, the fitting recess of the holder fits into the outer ridge part side of the fitting part formed by the inner ridge part and the outer ridge part. At the same time, the tip of the outer bezel is engaged with the engagement groove in the engagement portion of the locking tool, and when the locking tool is closed toward the holder, the tip end surface of the outer bevel is aligned with the slope of the engaging groove. Since it comes into contact with the surface and is locked, it can be bent inside the inner rib portion without coming off from the engaging portion.

(Example) An example of the present invention will be described below based on the drawings.

The crimping machine A of the present invention has gripping rods 1 and 1' formed to be freely openable and closable around the tip thereof;
Holder 2 and fastener 3 attached to the tip of 1'
It is composed of

The gripping rods 1 and 1' are provided with gripping parts 1a and 1'a at the upper part, and an inverted U-shaped connecting part 1 at the lower part.
b, 1'b are provided, and the connecting piece 1c of the connecting part 1b,
1'c are stacked on top of each other and rotatably connected by a rotating shaft 4, and a holder 2 and a fastener 3 are attached to the distal end sides of these connecting parts 1b and 1'b, respectively.

The holder 2 is attached to the tip of one of the gripping rods 1 at an appropriate distance from the rotating shaft 4 via a fixing piece 1d, and the outer edge of the fitting part m of the folded plate is attached to the front surface 2a, that is, the side surface of the rotating shaft. A curved fitting recess 5 that fits toward the b side is formed.

The holding tool 2 is for bending the tip b1 of the outer holding member b into the inner side of the inner holding member a, and is fixed to the tip of the other gripping rod 1' directly below the rotating shaft 4 in the same way as the holding tool 2. It is attached via piece 1d. Further, an engaging portion 6 is formed on the front surface of the fastener 3, that is, a surface facing the fitting recess 5 of the holder 2, and an engaging groove 7 is formed in the engaging portion 6.

The engagement groove 7 is engaged with the tip end b1 of the outer bar b, and is formed in a substantially V-shape or concave shape.
Further, the engagement groove 7 is formed such that the upper protrusion 7a projects more forward than the lower protrusion 7b, so that the tip b1 of the outer bar b can be easily hooked thereon.

Since the engaging portion 6 is formed with a V-shaped or concave engaging groove 7, when the distal end b1 of the outer bar b is engaged, the distal end surface b2 of the engaging groove 7 is aligned with the inclination of the engaging groove 7. Face 6
It is received by a and locked.

Therefore, even if the lock fastener 3 moves toward the holder 2, the tip b1 of the outer lock b will not come off the engaging portion 6.

Next, the connection of the folded plates M by the caulking machine A of the present invention will be explained.

First, the holder 2 and the fastener 3 are opened at appropriate intervals, and the fitting recess 6 of the holder 2 is opened so that the inner ridge part a and the outer ridge part b of the adjacent folded plate M are fitted. It fits into the outer rib part b side of the fitting part m formed by the above-mentioned.

Then, the tip part b1 of the outer bar part b is engaged with the engagement groove 7 in the engagement part 6 of the bar fastener 3.

At this time, the distal end surface b2 of the distal end portion b1 is received by the inclined surface 6a of the engagement groove 7.

Next, by closing the fastener 3 toward the holder 2, the tip b1 of the outer bead b is bent inside the inner bead a and tightened, and the folded plates M are integrally connected. Ru.

After the folded plates M are connected, the fastening tool 3 is separated from the holder 2 side again, the holder 2 is removed from the outer frame part b, and the crimping machine A is removed from the fitting part m of the folded plate M. remove.

(Effects of the invention) Since the invention has the above-described configuration, it has the following effects.

Since an engagement groove is provided in the engagement part of the locking tool, when the tip of the outer lock part is engaged with the engagement groove and bent,
Since the tip end surface is received and locked by the inclined surface of the engagement groove, the tip portion does not come off from the engagement groove, making the bending easy and smooth, and improving work efficiency. I can do it.
