Abstract

This creation is a double-knife eight-character cutting machine, which is used to cut a building material board, and includes a base and at least one cutting unit. The cutting unit includes two cutting machines. The two cutting machines are arranged horizontally and inclined to each other. The two blades are inclined towards the base. When in use, the building material board is placed on the base, and then the building material board is pushed toward the cutting unit, so that the top surface of the building material board faces the cutting unit, and a figure-eight groove is cut by the blades of the two cutting machines. When in use, it only needs to directly push the building material board, the action is simple and labor-saving and not easy to shake, and therefore the processing speed can be greatly increased. In addition, the relative positions and angles of the two cutting machines of the cutting unit are fixed, so the spacing, depth and angle of the figure-eight grooves cut each time are bound to be fixed, so that the figure-eight grooves of the same shape can be cut accurately.

Description

Double-knife figure-eight cutting machine

The invention relates to a cutting machine for building material boards, especially a cutting machine for cutting specific grooves on building material boards so as to be combined with connecting pieces on walls or ceilings.

In the prior art, when installing the building material board on the wall, if the building material board is heavy (eg, stone) or pays more attention to safety, dry construction is often used to fix the building material board. The common dry construction is to use two L-shaped boards between the wall and the building material board. The upright boards of the two L-shaped boards are respectively locked on the wall and the building material board, and the horizontal boards of the two L-shaped boards are up and down. After stacking and abutting, finally, a carriage bolt is used to vertically penetrate and lock the horizontal plate body of the two L-shaped plates, thereby fixing the building material plate body to the wall through the two L-shaped plates.

However, such an assembly method is very troublesome, so a figure-eight iron piece was developed later. Please refer to FIG. 10 . The inner side of the building material board 91 is formed with two figure-eight grooves 911 , while the figure-eight iron piece 92 is formed with two figure-eight grooves 911 . By engaging in the figure-eight groove 911 , the building material board 91 can be quickly and conveniently fixed.

However, the aforementioned problem is that the figure-eight grooves 911 are difficult to cut and form quickly. In the prior art, workers are required to directly hold a hand-held grinder to cut and form the inner side surface of the building material board body 91 . However, the rotating speed of the hand-held grinder is high, and it is easy to shake when cutting. It is very laborious to hold the grinder manually and it is difficult to accurately control the attitude of the grinder, which makes the position, inclination angle and cutting depth of the splay groove 911 difficult to control. In particular, if the angles, spacings and depths of the two figure-eight grooves 911 do not correspond to each other accurately, it is difficult for the figure-eight iron pieces 92 to be engaged therein.

In addition, multiple groups of figure-eight grooves 911 are often provided on the building material board 91 , and the angles, spacings and depths of the figure-eight grooves 911 in different groups must be the same, otherwise it is also difficult for the figure-eight iron pieces 92 to engage therein.

Furthermore, also because there are a plurality of figure-eight grooves 911 on the building material plate body 91 to be processed, it is very time-consuming to move the grinder from one figure-eight-shaped groove 911 to another figure-eight-shaped groove 911 , resulting in the speed of operation. slow. In addition, in order to minimize errors in the spacing, inclination angle and cutting depth of the figure-eight grooves 911, the worker needs to carefully control the grinder, resulting in slower operation.

Finally, manpower can only hold and operate one grinder at a time, so only half of the figure-eight grooves 911 can be cut at a time, so the operation efficiency is seriously insufficient.

Under the current situation that the whole world is faced with related problems such as lack of labor, lack of manpower and technical proficiency, it is impossible to improve the efficiency of cutting and forming the figure-eight grooves 911, and it is difficult to effectively use the figure-eight iron pieces 92 to quickly fix the building material plate body 91 advantages.

In view of the aforementioned shortcomings and deficiencies of the prior art, the present invention provides a double-knife figure-eight cutting machine, which can conveniently and quickly cut figure-eight grooves on a building material board.
