Description

[Detailed explanation of the idea] The present invention relates to a multiple punch with a tape measure.

Generally, when punching a section steel such as an H section steel or a channel steel, punching is often performed at multiple locations on the same line in the width direction of the section steel.

In that case, first measure the distance from one end of the shaped steel with a tape measure, then measure the distance from the side edge in the width direction using a ruler and a ruler, and find the point where they intersect, that is, the punching point. After marking with a scribing needle, the final step is punching with a punch and hammer.

However, this method requires the use of multiple types of tools, which makes the work complicated and time-consuming, and the punching tends to be inaccurate, which has a negative impact on the accuracy of subsequent drilling operations. There is.

In view of these points, the present invention aims to provide a multiple punch with a tape measure that has a simple construction, yet allows anyone to perform the above-mentioned operations accurately and quickly.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
In the figure, reference numeral 1 denotes a guide that is slid along one side of the mA shape, and a holder 2 is attached to one side of the guide at right angles so that its lower surface is located above the lower surface of the guide 1.

This holder 2 has a long hole 3 in its center extending in the longitudinal direction.
In addition, grooves 4a and 4b are provided at appropriate positions on both side surfaces parallel to the grooves.

In the figure, reference numerals 5a and 5b are punch holders installed over the holder 2, and both ends thereof are bent inward, and the grooves 4a,
4b so that the punch holders 5a and 5b do not easily come off from the holder 2 and are smoothly attached to the holder 2.
It serves as a guide claw so that it can be slid on top.

In addition, punches 6a and 6b are placed in the center of the top plate of each of the punch holders 5a and 5b so that their tip portions are located within the space of the elongated hole 3 provided in the holder 2, and in parallel with the holder 2. In addition to being installed in a straight line,
Its head and punch holder 5a.

Is there a spring between it and the top plate part of 5b? av7b is fitted externally.

The punch 6a is activated by these springs 7a and 7b. 6b is always pushed upward so that its tip does not protrude below the bottom surface of the holder 2.

Note that the number of punches is not limited to the above, and may be only one, or three or more.

In addition, stoppers 8a and 8b are attached to the side plates of the punch holders 5a and 5b.
a, 5b can be securely fixed in a predetermined position of the holder 2.

Note that the stoppers 8a and 8b are not limited to the screw type shown in FIG. 2, and any means may be used as long as the punch holders 5a and 5b can be easily and firmly fixed to the holder 2. It may be attached not only to one side plate but also to both side plates, the top plate, or both the side plate and the top plate.

In the figure, 9 indicates a tape measure attachment piece 1 provided at one end of the holder 2.
A tape measure attached to the holder 2 via a 0.10 mm tape measure is used, and has an elastic body for rewinding the tape-like ruler 11 that has been pulled out.

The scale of the tape-like difference 11 does not start from O unlike a general one, and is located between the center of the tips of the punches 6a and 6b and the outlet 12 of the tape-like difference 11, that is, the tape-like difference 1
1 is started from a value equal to the distance from the tip 13 of the tape-like ruler 11 when it is completely wound.

Therefore, the tape-like ruler 11 is pulled out and its outlet 12 is pulled out.
Just by reading the scale at the point, you can instantly know the exact location of the pong.

Further, it is convenient if the tip 13 of the tape-like ruler 11 is hook-shaped so that it can be hooked onto one end of the shaped steel.

Note that the tape measure 9 is not limited to the one described above, and may be a hand-wound one, and it is convenient if it is detachably attached to the tape measure attachment pieces 10 and 10.

FIG. 3 shows another embodiment of the present invention, in which the holder 14 has a long hole as shown in FIG. Punch 16 on the extended part.
a, 16b, and 16c are provided through them.

In the figure, 17a, 17b, and 17c are stoppers for fixing the punch holders 15a, 15b, and 15c to the holder 14, respectively.
It is installed on the top plate.

However, in order to perform punching using the multiple punch with tape measure of the present invention constructed as described above, first the required number of punches are fixed in a predetermined position of the holder with a stopper, and then the guide is applied to one side of the section steel. At the same time, hook the tip of the tape measure to one end of the shaped steel and slide the guide along one side of the shaped steel.

At that time, read the scales on the tape-like rulers that are unrolled one after another at the drawer opening.

Then, when you reach your destination, stop there.
Hit the punch with a hammer.

This completes the required number of punches on the same straight line in the width direction of the shaped steel.

The present invention as described above has the following effects.

a) Since the tools necessary for punching work are combined into one, there is no need to use various tools interchangeably as in the past, improving work efficiency.

b) Accurate punching points can be obtained by simply setting the required number of punches in predetermined positions and then reading the scale on the tape-like ruler.

Furthermore, subsequent work such as drilling holes can be performed accurately.

d It is easy to handle and allows accurate punching, so even inexperienced workers can work with confidence.

e It has a simple structure and can be mass-produced at low cost.
