Abstract

The present invention provides a wide material saw guide for cutting a wide work plate material with a hand saw into a straight line. A square metal plate having an arbitrary thickness and size is bent at a right angle in a ratio of 1: 2 to form an L-shaped member, and a portion corresponding to the ratio of 1 is a bottom surface portion 4a fixed together with a work plate material, 2 is applied to the rising part corresponding to the ratio of 2 with the opening of the separately formed U-shaped member on the bottom, the outer side of the L-shaped member being in close contact with the rising part of the L-shaped member, and passing the bolt. The punching process of extending the left and right holes of the L-shaped member is made to make the U-shaped member movable forward and backward, and the other side of the U-shaped member is formed in a downward semicircular shape. The member formed separately in (2) was formed by fixing two semicircular members through a member formed separately having a narrow width close to the thickness of the hand saw.

Description

The present invention relates to an instrument for cutting a wide work board material linearly with a hand saw.

A conventional saw guide has a structure in which a member fixed in close contact with a work plate material and a hand saw sandwiching portion are integrated and fixed together with the work material plate. In the case of a wide work sheet material, the hand saw must be positioned as far forward as possible, and then only the tip of the hand saw must be moved in small increments to cut it. Although it is possible to change the position by loosening the fixed member, it takes time, and it is predicted that the cutting position is shifted, and there is a problem in accuracy. There is also a bearing type, but it does not support wide work plate materials.

When cutting a wide work plate with a conventional saw guide, it has to be cut only with the tip of the hand saw, which is time consuming and inefficient.

A square metal plate having an arbitrary thickness and size is bent at a right angle in a ratio of 1: 2, and 4b corresponding to a ratio of 2 becomes a rising portion. The other 4a is brought into close contact with the work plate and fixed together with the work table.

At a distance of 2 cm from the top of 4b, a horizontally long punching process having a width of 6 mm is performed.

The U-shaped members 1a, 1b, and 1c that are half the width of 4a and 4b are formed.

With the opening of the U-shaped member facing down, a horizontal long punching process with a width of 6 mm is performed at 2 cm from the top of 1a.

The lower part of 1c is cut into a semicircle.

The same shape as 1c is cut out from another plate to form 2, and a thin plate having an arbitrary material of about 0.7 mm is sandwiched between the upper parts and fixed with screws, and a movable hand saw is moved back and forth. Let it be a pinch part.

Cover the top so that the punched part of 4b and the punched part of 1a match, and pass the bolt through the bolt to slide it to any position to form a wide saw saw guide that can be fixed with a nut. .

As a result, when cutting a wide work sheet material, it is possible to move using the entire hand saw blade by moving the hand saw sandwiching part according to the cutting position, improving work efficiency and accuracy To do.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The wide guide saw guides 4a and 4b of the present invention are fixed to the center of the width of the wide workpiece plate material by a vise or the like.

Loosen the nut 6 to which the hand saw clip portion 1a, 1b, 1c and 4b are fixed, move the hand saw clip portion forward, tighten the nut 6, and sandwich the hand saw between 1c and 2 Start cutting with.

Depending on the progress of the cutting, the hand saw pinching portion is moved to the front, and cutting is started again.

The range of motion before and after the hand saw pinching portion is 30 cm, and the blade of the hand saw is located further forward than this, so that it is possible to cope with wider plate materials.

The present invention is used in the industry for manufacturing DIY articles.

Claims (1)

A member that can be fixed with a work table by bending a square metal plate having an arbitrary thickness and size at a right angle of 1 to 2, with 4b corresponding to 2 as the rising portion, and the other 4a being in close contact with the work plate material 2b from the top of 4b is subjected to a 6 mm wide punching process to form a U-shaped member of 1a, 1b, 1c that is half the width of 4a, 4b, and the opening of the U-shaped member 2cm from the top of 1a with a width of 6mm, cut the bottom of 1c into a semicircular shape, cut out the same shape as 1c from another plate, A 4b punching portion and a 1a punching portion are formed by forming a front and rear movable hand saw sandwiching portion formed by sandwiching a thin plate having an arbitrary material of about 0.7 mm between the upper portion and fixing with a screw. Cover the top with a bolt Te hand saw nip slide to an arbitrary position, saw guide wide material that can be fixed with a nut.
