[Structure] The top plate and the bottom plate can be fixed in parallel to each other so that the distance between them can be adjusted, and a cutter that is slanted between the top plate and the bottom plate inserts and slides between the top and bottom plates to cut the backup material, etc. A cutter that cuts and cuts things.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cutter for a backup material, which is made of foamed urethane or the like, which is used by being attached to or interleaved with a building mold or the like.

[0002]

[Prior art]

 Conventionally, when cutting a backup material, etc., a curved scale is placed on the backup material, and the blade of a knife-shaped cutter is moved along the curved scale to perform the cutting.

[0003]

[Problems to be solved by the device]

 With the conventional cutting method, the length of the cutting is limited to the length of the curved scale, and it is difficult to adjust the cutting width. Also, when cutting a thick backup material, it is difficult to cut the cut section vertically, and it is also difficult to cut the cut surface into a clean flat surface.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention provides a device capable of vertically cutting an arbitrary width by sliding the inside of the cutter with a backup material of any thickness.

Therefore, the present invention comprises a cutting width adjusting part, a cutter blade holding part, and a thickness adjusting part. The width adjusting part is provided with a cutter blade holding part and slides in the guide groove to set the width. The cutter blade holding part has two parallel plates and fasteners such as bolts for tightening the two plates. I'm trying to stick to it. Then, the side edge of the upper plate having this width adjusting portion is made of an angle member bent at a right angle, and the angle member of the lower plate having the side edge part similarly bent is superposed on the lower portion. The screw fixed to the bent side surface of the lower plate is inserted into the vertical groove provided on the bent side surface of the upper plate, and the nut is tightened to the bent side surface of the upper plate. Further, the front end of the flat plate of the lower plate extends longer than the upper plate, and a guide groove for supporting and guiding the tip of the cutter blade held by the upper plate is provided.

[0006]

[Action]

 According to the thickness of the backup material to be cut, the gap between the upper and lower plates is adjusted by the thickness adjustment unit, the cutter blade is attached to the cutter holding unit, and the tip blade is supported in the guide groove at the front end of the lower plate. The cutting width adjustment part, which is formed integrally with the cutter blade holding part, is slid sideways in the guide groove to fix it, thereby adjusting the distance between the side surface of the upper plate and the cutter blade, and cutting. Adjust the width. After that, the back-up material is cut between the upper plate and the lower plate by advancing the back-up material toward the cutter blade to cut the back-up material with a width corresponding to the adjustment width.

[0007]

【Example】

 Next, an explanation will be given according to an embodiment shown in the drawing.

The upper plate 1 is an angle member, and the side end is bent at a right angle to form a side surface portion 2. The front end portion 1 a of the upper plate 1 is provided with a scale 3 and further, A guide groove 4 is provided along the scale 3. A cutting width adjusting portion 6 having a cutter blade holding portion 5 and capable of sliding and fixing in the guide groove 4 is engaged with the guide groove 4.

A lower plate 7 which is inwardly overlapped with the upper plate 1 in a plane parallel to the upper plate 1 has a side plate 8 whose side ends are bent at a right angle, like the upper plate 1. The protruding screw 9 is inserted into a vertical groove 10 formed in the side surface portion 2 of the upper plate 1 overlapping the side surface plate 8 of the lower plate 7 and fixed by a wing nut 11 or the like. The thickness adjusting portion 12 is configured to adjust the distance between the lower plate 7 and the lower plate 7.

This makes it possible to cope with various thicknesses of the backup material 16. Further, in the embodiment, the two thickness adjusting portions 12 are shown so that the lower plate 2 can be firmly fixed to the upper plate 1.

The cutter blade holding portion 5 is configured to clamp and hold the head of the cutter blade 14 with the two parallel plates 13, and the tip 14 a of the cutter blade 14 extends forward from the upper plate 1. It engages in a guide groove 15 provided at the front end of the lower plate 7 and supports the tip of the cutter blade so that it does not move when the backup material 16 is cut. The groove opening of the guide groove 15 is preferably formed obliquely in correspondence with the inclination of the cutter blade, and the vertical groove 10 of the thickness adjusting portion 12 also has a large thickness depending on the thickness of the backup material 16. The lower plate 7 extends from the front end of the upper plate, and the guide groove 15 for supporting the tip 14a of the cutter blade is provided so that the cutter blade 14 is more inclined when it is cut and can be cut with less force when cutting. It is advantageous that the vertical groove 10 of the thickness adjusting portion 12 is formed obliquely so that the lower part of the groove is inclined forward so that it also advances forward A.

[0012]

[Effect of device]

 According to the present invention, the presence of the thickness adjusting unit enables to cope with an object to be cut such as a backup material having any thickness, and the cutting can be easily performed simply by sliding in the cutter, and the cutting width can be arbitrarily set. Since the vertical groove of the thickness adjusting part is formed so that the angle of the cutter blade can be adjusted according to the thickness of the object to be cut, even a thick object can be cut with a weak force.
