Description

Double-blade eight-shaped cutting machine

The present invention relates to a cutting machine for building material panels, and in particular, to a cutting machine that cuts specific grooves on building material panels so that they can be combined with connectors on walls or ceilings.

In the prior art, when installing building material panels on the wall, dry construction is often used to fix the building material panels if the building material panels are heavy (such as stone) or when safety is of great concern. The common dry construction method is to use two L-shaped plates between the wall and the building material plate. The upright plates of the two L-shaped plates are locked on the wall and the building material plate respectively, and the horizontal plates of the two L-shaped plates are locked up and down. After stacking and abutting, a carriage bolt is used to vertically penetrate 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 later a figure-eight iron piece was developed. Please refer to Figure 10. The inner side of the building material plate 91 is formed with two figure-eight grooves 911, and the figure-eight iron piece 92 is It snaps into the eight-shaped groove 911, thereby quickly and conveniently fixing the building material board 91.

However, the aforementioned problem is that the eight-shaped groove 911 is difficult to cut and form quickly. In the prior art, workers directly hold a handheld grinder to cut and form the groove on the inner side of the building material plate 91 . However, the handheld grinder has a high rotational speed and is prone to shaking during cutting. It is very laborious to hold the grinder manually and it is difficult to accurately control the posture of the grinder, making it difficult to control the position, inclination angle and cutting depth of the eight-shaped groove 911. In particular, if the angle, spacing, and depth of the two eight-shaped grooves 911 do not accurately correspond to each other, it will be difficult for the eight-shaped iron piece 92 to engage therein.

In addition, multiple sets of eight-shaped grooves 911 are often provided on the building material plate body 91. The angles, spacing, and depths of different groups of eight-shaped grooves 911 need to be the same, otherwise it will be difficult for the eight-shaped iron parts 92 to engage therein.

Furthermore, because there are multiple splayed grooves 911 on the building material board 91 that need to be processed, it is very time-consuming to move the grinder from one splayed groove 911 to another splayed groove 911 , resulting in a slow operation. Slowly. Moreover, in order to minimize errors in the spacing, inclination angle and cutting depth of the eight-shaped grooves 911, workers need to carefully control the grinder, resulting in slower operation.

Finally, manpower can only hold and operate one grinder at a time, so it can only cut half of the eight-shaped groove 911 at a time, so the operating efficiency is seriously insufficient.

At present, the whole world is facing related problems such as labor shortage, insufficient manpower and technical proficiency. If the efficiency of cutting and forming the figure-eight groove 911 cannot be improved, it will be difficult to effectively use the figure-eight iron piece 92 to quickly fix the building material plate 91 The advantages.

In view of the above-mentioned shortcomings and shortcomings of the prior art, the present invention provides a double-blade eight-shaped cutting machine that can easily and quickly cut eight-shaped grooves on building material panels.
