Background technique

In construction engineering, it is common to paste cut and surface-treated stone slabs on the wall to decorate the wall or ground of the building. Most of these stone slabs are taken from natural raw stones after many times of cutting, and then It is made by surface treatment; or the above-mentioned stone slabs are manufactured by man-made methods, and a large area of stone slabs is firstly produced, and then cut to the required size as required.

In the manufacturing process of the above-mentioned stone slabs, the cutting methods adopted currently include sawing methods such as sawing with a water jet, sawing with a wire saw, sawing with a circular saw blade, or milling with a milling cutter, or grinding with a grinding wheel. method, the above-mentioned processing method has the following disadvantages in application:

1. The cutting stroke is extremely long, and the stroke feed is very slow, so the cutting operation is very time-consuming.

2. When cutting, a large amount of water must be used for cooling.

3. When milling, sawing and grinding, a large amount of dust will be generated, which will seriously pollute the air environment and damage the health of the operators.

4. Due to the extremely lengthy cutting time, the manufacturing cost is relatively increased.

5. Because the machining profile of the wire saw, milling cutter, and grinding wheel on the slate is long, that is, the cutting distance is very long, so the tool consumption is extremely large.

In recent years, it has been used to carry out up-and-down biting-type slow biting on both sides of stone slabs through a press, as shown in Figure 21 and Figure 22, the biting die set 50 includes a movable biting die 50a and a fixed biting die 50b, wherein the movable biting mold 50a and the fixed biting mold 50b are aligned with each other up and down, and its section is wedge-shaped. The movable biting mold 50a is driven by the biting actuating mechanism 53 to move up and down so as to approach or move away from the fixed biting mold 50b. The movable biting die 50 a and the fixed biting die 50 b of the biting die set 50 each have a biting edge 54 with the same profile as the predetermined cutting line T of the stone plate 52 .

The stone plate 52 is placed on the fixed biting mold 50b, and the movable biting mold 50a is provided with a biting actuating mechanism 53, so that the movable biting mold 50a is slowly approached towards the fixed biting mold 50b and the stone plate 52, and the The movable biting die 50a and the fixed biting die 50b are aligned up and down, and the upper and lower sides of the stone plate 52 are bitten, so that the stone plate 52 can be made to move along the upper and lower sides of the movable biting die 50a and the fixed biting die 50b. Broken at the tip.

The above processing method has the following disadvantages in application:

1. In the above method, when the movable biting die 50a and the fixed biting die 50b bite the stone plate 52 up and down slowly, the material of the stone plate 52 is extremely hard and brittle, and it is not easy to form a straight Therefore, the outline of the cut surface 52' of the bitten-cut stone plate 52 is extremely uneven, and its fragmentation shape cannot be predicted, so a jagged irregular outline is often produced.

2. No matter whether it is too thick or too thin, this method of biting up and down and biting slowly is not suitable. Because it cannot be bitten off when it is too thick; it is easy to be irregular and brittle when it is too thin.

3. Due to the extremely high failure rate in manufacturing, it is not widely used.
