Description

  The present invention relates to a sheet metal gripping tool.

  As a conventional sheet metal gripping tool, when each return part is opened, the pinion of the fulcrum meshes with the rack and rotates and moves away from each return part, making each return part easier to open and opening each return part. When closing, the pinion of the fulcrum meshes with the rack, rotates and moves in a direction approaching each return part, and makes it easy to apply a large force to each return part (for example, see Patent Document 1 or 2), and each return When the part is opened, it has a groove hole that opens from the tip of each return part, and by inserting the sheet metal up to the groove hole, it is possible to perform processing such as bending at a deep position of the sheet metal (for example, Patent Document 2 or 3) has been developed by the present inventors.

  When using a conventional sheet metal gripping tool as described in Patent Documents 1 to 3 to fold a sheet metal such as a roof tin plate, a skilled worker can fold the sheet metal at a predetermined position depending on intuition. it can. However, in order for an unskilled person to bend at an accurate position, it is necessary to perform work while measuring the length and determining the bending position, and there is a problem that time and labor are required for the work.

  The present invention has been made paying attention to such a problem, and provides a sheet metal gripping tool which can bend a sheet metal at an accurate position without requiring skill and can improve work efficiency. The purpose is that.

  In order to achieve the above object, a sheet metal gripping tool according to the present invention is a sheet metal gripping tool for folding a sheet metal between a pair of openable and closable return parts, and at least one of the return parts It has a scale on the outer side surface from the front end to the rear end.

  The sheet metal gripping tool according to the present invention can be bent at an accurate position even if it is not skilled, by aligning the edge of the sheet metal with a scale of a length to be bent and bending the sheet metal by sandwiching the sheet metal between the return portions. Thereby, work efficiency can be improved.

The scale may be provided on the outer surface of one return portion or may be provided on the outer surfaces of both return portions. The scale may be printed on the outer surface of the return portion, or may be composed of grooves or protrusions formed on the outer surface. The unit of the scale is, for example, the part of the shank method, mm, cm, or the like.
The sheet metal gripping tool according to the present invention may have a notch corresponding to the scale on the side edge of each return portion. The notch is formed by, for example, a cut or a step.

  According to the present invention, it is possible to provide a sheet metal gripping tool capable of bending a sheet metal at an accurate position without requiring skill and improving work efficiency.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a sheet metal gripping tool according to an embodiment of the present invention.
As shown in FIGS. 1 to 3, the sheet metal gripping tool 1 includes a first handle 2, a second handle 3, and a shaft member 4. The sheet metal gripping tool 1 is a tool commonly referred to as “tsukami”. For example, when rolling a tin roof, a plurality of stacked tin plates are crimped and bent at the end, and subjected to caulking, It is used when filing.

  As shown in FIGS. 1 to 3, the first handle 2 has a handle 21 on the rear end side and a return portion 22 on the front end side. The handle 21 is provided with a non-slip. The return portion 22 is formed so as to be wider than the length in the front-rear direction, and has a flat crimping surface 23 on the inner side. The first handle 2 is provided so as to continuously extend from the crimping surface 23 in the direction of the handle 21 and to extend from the central portion toward the distal end and face the groove 24. And a protruding portion 25. The protrusion 25 has a mounting hole penetrating in the width direction at the tip.

  The first handle 2 has a scale 26 on the outer surface of the return portion 22 and the outer surface of the handle 21 from the front end toward the rear end. The scale 26 is engraved with a line extending in the width direction corresponding to the distance from the tip. The scale 26 is provided from the tip of the return portion 22 to the position of the rear end of the slot 24 of the handle 21. As shown in FIG. 2, a numerical value indicating the length from the tip of the return portion 22 is displayed on the scale 26. The unit of the scale 26 is, for example, the scale method.

  As shown in FIGS. 1 to 3, the second handle 3 has a handle 31 on the rear end side and a return portion 32 on the front end side. The handle 31 is provided with a non-slip. The return portion 32 has the same width as the return portion 22 of the first handle 2 and is formed to be wider than the length in the front-rear direction, and has a flat crimping surface 33 on the inner side. The tips of the return portions 22 and 32 are perpendicular to the length direction of the first handle 2 and the second handle 3. The second handle 3 has a mounting hole penetrating in the width direction in the vicinity of the root of the return portion 32 on the tip side of the handle 31.

The shaft member 4 is inserted into the attachment hole of the first handle 2 and the attachment hole of the second handle 3, and rotatably attaches the first handle 2 and the second handle 3 to each other. As shown in FIG. 1, in the sheet metal gripping tool 1, when the handles 21, 31 are closed and the return portions 22, 32 are closed, the crimping surfaces 23, 33 of the first handle 2 and the second handle 3 are They overlap each other. Further, as shown in FIG. 3, in the sheet metal gripping tool 1, when each handle 21, 31 is opened and each return portion 22, 32 is opened, the slot 24 communicates from the tip of each return portion 22, 32. To open.
Note that the sheet metal gripping tool 1 may be a type in which the return portions 22 and 32 are inclined with respect to the length direction of the first handle 2 and the second handle 3 or a straight type.

Next, the operation will be described.
The sheet metal gripping tool 1 is configured such that a sheet metal such as a tin roof is sandwiched between the wide return portions 22 and 32 with the handles 21 and 31 opened, and the sheet metal is bent and subjected to a caulking process or a brazing process. It can be carried out. By inserting the sheet metal from the tip of each return portion 22, 32 to the slot 24, bending can be performed at a deep position of the sheet metal. At this time, since there is a scale 26 corresponding to the distance from the tip of the return portion 22 from the tip of the return portion 22 of the first handle 2 to the position of the rear end of the slot 24 of the handle 21, By aligning the edge 26 with the scale 26 of the length to be bent and bending the sheet metal between the return portions 22 and 32, the sheet metal can be bent at an accurate position even if it is not skilled, and work efficiency can be improved. I can do it.

  The scale 26 may be formed by notches formed on the side edges on both sides in the width direction corresponding to the distance from the tip of the return portion 22. The notch may consist of a V-shaped cut 51 as shown in FIG. 4 (a) or a step 52 as shown in FIG. 4 (b). In this case, by aligning the edge of the sheet metal with the notch 51 or the step 52 of the scale 26 having a length desired to be folded, the sheet metal is sandwiched between the return portions 22 and 32 to be folded at an accurate position even if not skilled. it can.
