JPS5927942Y2 - Jigs and tools for processing gutter holder hardware - Google Patents

Description

[Detailed Description of the Invention] This invention relates to processing jigs and tools used when performing various processing on a gutter holder, particularly in a pre-processing process for attaching the gutter holder, which supports eaves gutters, to a certain tree, for example.

Conventionally, when installing a gutter using a gutter bracket at the edge of an eaves, etc., in order to improve the flow of rainwater, the gutter bracket is shaped to have a height difference, thereby creating a height difference in the gutter.

When forming the minimum difference in each of these gutter holder metal fittings, normally the arm part of the gutter holder metal piece that is continuous with the gutter holder part is processed so that the gutter holder part becomes lower (higher) in sequence, but there are various methods. The above-mentioned processing is easy in a sheet metal workshop where all the tools are available, but at the site where it is actually carried out, there are only limited tools and it is difficult.

Therefore, the present invention is designed to bend a gutter holder having an arm with a rectangular cross section not only in the thickness direction of the arm part, but also in the width direction, which is difficult to bend, at the construction site. It is an object of the present invention to provide a processing jig and tool for gutter receiving metal parts that can be easily processed.

Embodiments of this invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a surface plate, 2 is an anvil member, and on the upper surface of one side of the surface plate 1, a pair of crane-shaped bending grooves 3 having a predetermined curvature and serving as a gauge are provided. , these bending grooves 3 that also serve as gauges are arranged in the direction of arrow A shown in FIG.
, can be opened and closed by a presser plate 5 that rotates in directions B.

The anvil member 2 is removably attached to the surface plate 1 by, for example, screwing a male threaded portion 6 protruding from its lower end into a female thread 7 formed on the surface plate 1. In addition to forming a contact surface 9 made of a straight line with the surface 8 (see FIG. 3), a recess 10 with an open upper surface is provided as shown in FIG. Slits 11a, 11b, 12a, 1
2b are provided, and these slits 11a, 1
1 b, 12 a, 12 b (7) depth 11 D, 12
D is formed to be shallower than the depth D of the recess 10, and the width W1 of one of the slits 11a and 11b is set to a size that allows fitting and clamping according to the wall thickness of the arm portion of the gutter holder, which will be described later. The width W2 of the other slit 12a and 12b is set to be somewhat larger than the width W1 of the one slit 11a and 11b based on the wall thickness of the other arm part. are doing.

FIG. 5 shows a handle 13, which consists of a gripping part 14 with a circular cross-section and a holding part 15 with a square cross-section connected to the gripping part 14, and an axis of the holding part 15. Grooves 16 and 17 are formed on both sides.

These grooves 16 and 17 are fitted with arms of a gutter holder to be described later, and have a width dimension W4. W5 is set to a size that allows fitting according to the width dimension of the arm.

Reference numeral 18 indicates a slider, which is externally fitted onto the holding portion 15 of the handle 13 so as to be able to move back and forth, and which is connected to a set screw 19.
By screwing in, it is possible to securely fix the holding part 15 at any position.

In the above configuration, when the arm 22 connected to the receiving plate 21 of the gutter receiving metal fitting 20 shown in FIGS. 6 and 7 is bent in the width direction to have a crane-neck shape, for example, the arm 22
By bridging the straight arm 22 over the slit (11a11b) in which it is held (Fig. 8a), and then pressing the arm 22 with a hammer or the like in the direction of arrow C, it can be bent into the state shown in Fig. 8b.

When curving in the imaginary line direction shown in Fig. 8b, the anvil member 2 is removed from the surface plate 1 and laid down on the surface plate 1, the arm 22 is brought into contact with the curvature contact surface 8, and a hammer or the like is used to The arm 22 is pressed and bent in the direction of the above-mentioned imaginary line, and the bending groove 3 which also serves as a gauge is bent in the state shown in FIG. 8b.
The slits 11 a , 11 b , 1 are used when the slits 11 a , 11 b , 1
Instead of bending the arm 22 using the grooves 2a and 12b, it is also possible to bend the arm 22 as shown in FIG. 8b using the new groove 3 that also serves as a gauge.

During the above bending process, the arm 22 is fitted into one of the grooves 16 and 17 formed in the holding portion 15 of the handle 13, the slider 18 is moved to a predetermined position, and the set screw 19 is tightened and fixed. Since the arm 22 is firmly held by the handle 13, the above-mentioned bending operation can be performed stably and easily.

In addition, the slits 11a, 11b, or 12
a, bridge the arm 22 to 12b, and handle 13
The arm 22 can be twisted into the state shown in FIG. 8C by fitting it into the groove 16 or 17 of the holding part 15 and fixing it with the slider 18, and rotating the handle 13 around the axis. .

The slits 11a, 11b and 12a, 12
b may be selectively used according to the wall thickness of the arm 22, and the grooves 16 and 17 of the handle 13 may also be selectively used according to the width dimension of the arm 22.

The abutment surface 8 of the anvil member 2 can of course be used for other curved configurations, and the abutment surface 9 and the upper surface of the surface plate 1 can be used to correct distortion in the thickness direction of the arm 22.

The depth D of the recess 10 can be adjusted by inserting one or more depth adjustment members (not shown) having an appropriate thickness into the recess 10 of the anvil member 2. , the curvature and arc length at the time of bending shown in FIG. 7b can be adjusted and set.

As explained above, this invention has the advantage that it is possible to easily bend the arm in the thickness direction, as well as bend it in the width direction, as well as other bending and twisting processes. .
