Description

MARBLE BLOCK SAWING MACHINE WITH COAXIAL BLADES DRIVE SYSTEM Technical Field

The present invention relates to a hive system in the marble block cutting machines, which enables the marble and similar structures to be cut and carries out the cutting procedure, enables the activity of the two cutting parts with different diameters that are arranged side by side with certain spaces between them.

The said invention relates to a hive system which has the quality of adjusting the cutting speeds and/or cycles of the cutting parts that are arranged side by side with different diameters, in a way independent from each other, and which provokes these cutting parts that have the variable cycles on the same axis and direction and enables the machine to work at high performance.

The Background of the Invention

The marble block cutting machine used nowadays is, as a basic principle, a machine that carries out the cutting process on a stable marble block on the ground within the requested measures, as a result of the rotation of one or two circular saws through an electric engine and bell-wheel mechanism and of the activity of this system horizontally on a register called "bridge".

Present marble block cutting machines are composed of a bridge connected to the columns and a cabin moving in "x" direction and a hive connected to the cabin and the cutting parts connected to the hive which carry out the cutting process. (See Fig. 1 and 2)

The arrangement called as cabin in the said marble block cutting machines moves linearly in "x" direction laid through a linear laying system on the bridge. The cabin is moved back and forth with an engine-redactor group. The hive that the cutting parts are connected is connected to the cabin. The said hive arrangement is illustrated in the Fig-lc. In the present marble block cutting machines, the hive is a system that enables standard circular motion where a crowbar is lied in a machine part produced from steel or foundry that has connection legs in the shape of pipe, that to one of its ends the cutting parts or saws are connected, on the other end of it is the provoking wheel. On the moving crowbar, generally a single cutting part is connected. Normally two cutting parts can be connected. Two different cutting parts are rotated by a single crowbar. The peripheral speeds of the cutting parts which rotate with the same circular speed and which have different radius are different.

The cutting ability that is cutting performance is dependant directly on the cutting speed, cutting efficiency, the cutting speed of the cutting part compatible with marble and/or natural stone. Thus, when the peripheral speed is done in accordance with the cutting part of any diameter, the^' second cutting part or saw do not have the compatible cutting speed. In practice, the speed of the two cutting parts is determined by taking the medium of the cutting parts that have low and high speed. That appears as a serious problem that we face in the marble cutting technology.

Because of the different peripheral speeds of the cutting parts that have different diameters, by using two cutting parts, the cutting capacity can be increased very little. Because of the difficulty in the change of the cutting part and adjustment, it is not applied.

In a marble block cutting machine, one of the most significant reasons that reduce the cutting speed affecting the cutting process is the cutting depth. For example; while cutting a marble block of 3 m. in two minutes in the depth of 300 mm before, if the cutting depth is increased to 600 mm, the cutting process lasts for 3-4 minutes. As the depth increases, the weight on the saw is increased as well and thus the linear motion of the saw is disturbed. So the cutting process is fulfilled by reducing the progress speed.

In the present machines, to raise the capacity and the speed, double-cutting part is used and a diameter difference between the cutting parts is created and the cutting depth is divided among the two cutting parts, but the capacity improvement is very low because of the diameter differences, different peripheral and cutting speeds of the saws and cutting machines.

To write down the negative sides of the marble cutting machines used today;

• The capacity can not be raised to a level above a certain value, no matter how much increased the power of the engine. • The saw loses its linearity, and is damaged at high cutting, progressing speeds.

• The speed has to be very low especially at the deep (65 cm.) cutting processes.

• When the double-saw or in other terms double-cutting parts are used, the saws rotate at the same turnover and because of the difference in the diameters, a different peripheral cutting speed is created. This makes it inevitable for the saws to be converted from their ideal cutting speeds.

• At the deep cutting processes with one saw, as enough coolant fluid can not come into contact with the saw, the life of the saw is shortened.

• While using two saws, the thickness of the marble and/or stone to be cut is adjusted hardly.

Explanation of the Invention

The aim of the invention is that, different from the negative situations explained above, the saw and/or the cutting parts that carry out the cutting procedure fulfil the cutting procedure by rotating at different circulations in the same axis direction thus a high performance and efficiency are obtained.

An aim of the present invention is to consume less energy and to present a more economical machine through the cutting parts that have different circulations for an ideal adjustable cutting speed. Another aim of the present invention is to carry out the work done by two or more machines, through a single machine or a single engine .

Another aim of the present invention is to reduce the costs of labour and production by making a single labourer do the job done by two or three labourers .

Another aim of the present invention is to divide the weights on the cutting parts through the cutting parts that have different circulations and thus to lengthen the life of the cutting parts.

Another aim of the present invention is to enable the production at high capacity, low cost and high quality.

Another aim of the present invention is to enable disposal of time by shortening the saw exchange time and easing the thickness adjustment.

DETAILED EXPLANATION OF THE INVENTION

The marble block cutting machine comprises, columns (1) , bridge (2), cabin (3), hive system (4), cutting parts (34-38), concrete ground (5), side bridges (6), sub saw group (9), belt (7), and engine (8) and subgroups of them. The columns (1) are a steelworks in the "U" shape to keep the system where the bridge

(2) , side bridges (6) and the cabin (3) are connected to each other at a certain level .

The side bridges (6) are the parts where the bridge (2) is moved, that enable the bridge move in the "y" and "z" direction and that are produced by steel welding means in various dimensions and shapes.

The bridge (2) is the machine part where the cutting group [cabin

(3), -hive system (4), cutting parts (34-38), belt-wheel group

(7), engine (8), sub saw group (9)] are lied on the said cutting part is enabled to move in the "x" direction and which is produced by steel welding means in various dimensions and shapes. The cutting group is a group of parts where the machine parts such as cabin (3), hive system (4), cutting parts (34-38), the belt (7), engine (8) and sub saw group (9) are connected to each other, of which motivation in ^λλx direction realizes the cutting process, and which is formed by bringing several machine parts together.

In the embodiment, at least two cutting parts (34-38) are positioned and these parts carry out the cutting process of the marble and natural stone. In the machine, also concrete grounds

(5) are structures with iron blockage that are placed in accordance with the soil ground that enable the machine to be mounted on the ground rigidly.

The hive system (4) of the machine according to the present invention is illustrated in the Figure-4 and 5 in a general perspective, in the Figure-6 and Figure-8 in cross-sectional view and perspective cross-sectional view. In the Figure-4 and 5, the outlook of the machine according to the present invention is given from the front and rear view. In the Figure-9, the blown up view that is, the disassembling perspective view of the hive system is illustrated.

Here, with a single engine (8) that is with a single impulse, two independent impulses are obtained. A single gradual wheel (45) that is, a single wheel of different two diameters is on the output crowbar of the engine (8) . The engine (8) is chosen among the standard engine circulations in accordance with the design. With the circular motivation of the engine (8) , the two different belts (7) are conveyed to the hive system (4) . As illustrated in the Figure-7 and 8, the main saw hive (10) is a machine part that makes the heat transmission through the foundry and steel easy, and that has a good endurance .

The main saw hive (10) is lied on the main saw hive (10) with the inner hive (16) produced from steel, the Cylindered Bearing of double park (17) and Ball Bearing with Conical Reels (11) . The main saw crowbar (22) is produced from a special steel-alloyed material. The main saw crowbar (22) is laid on the inner hive

(16) with the bearings (11 and 25) . Here, the inner hive (16) and the main saw crowbar (22) move independently of each other. The flange (32) is fixed on the inner hive (16) and the saw is fixed on the flange (32) . The saw is rotated by the wheel (27) . The wheel (27) is fixed on the inner hive (16) . The saw (38) is laid on the main saw crowbar (22) and the saw (38) is designed in a way to move in ^λ>x" direction .-

The saw (38) is rotated by the wheel (29) . The impulse taken from the engine (8) is conveyed to the hive system (4) through two different belts (7) . As the hive system (4) according to the present invention is comprised of two telescopic hives (10, 16) , the saws (34, 38) can move independently from each other. Thus; through the exchange of the wheel diameters (27, 29) compatible peripheral speeds for each saw (34, 38) can be obtained.

Besides that we obtain different circulations from the hive system (4) according to the present invention, one of the saws (34) can be fixed and the other (38) can move in the "x" direction. That is, the saw (38) as large as the stone to be cut, can move. So, the adjustable saw (38) allows the required stone thickness .

For the system to operate effectively, the saws (34, 38) of two different diameters are chosen. Here, the aim is to load equal cutting works on each saw.

For example;

Let the diameter of the saw no: 38 be 1750 mm

And the saw no: 34 be 1100 mm.

1750-1100 = 650:2 = 325 mm is the odds between the two saws.

If we carry out the cutting process at a depth of 650 mm, the saw that has a diameter of 1750 mm will cut 325 mm and the saw that has a diameter of 1100 mm will cut 650-325 = 325 mm. Thus, each saw will cut at equal depths. Herein the saws (34, 38) will be exposed to equal weights. The ideal cutting conditions will be obtained as their cutting speeds can be adjusted.

The mathematical analysis of the present invention;

Let's suppose that, to cut a marble or a natural stone of any quality, the ideal cutting speeds will be as following, basing our criterions on the producers, practical experiments and experiences; the peripheral speed of a saw that has a diameter of 1750 mm being 55m/s is the ideal cutting speed. We will call it "Vgl750".

Let us suppose the peripheral speed of 63 m/s as the ideal cutting speed of a saw that has a diameter of 1100 mm. let us call it "VςllOO"

In order to carry out a cutting process at 650 mm; suppose that we choose The large saw -> 01750 = 1750 mm diameter

The small saw -> 01100 = 1100 mm diameter as the saw diameters, for a cutting process at a depth of 650 mm, it will cut 325 mm with the saw 01100, and while the saw 01100 is carrying out a second cutting process, the saw 01750 will enter to the channel that the saw 01100 has cut before, and cut the rest 325 mm of the 650 mm. That is the saw 01100 will always carry out the first cutting process and the saw 01750 will enter to the channel that the saw 01100 has cut and it will increase the cutting depth to 650 mm. After the peripheral speeds are chosen, let us calculate the circular speeds of the saws (34, 38; VςllOO -> the circular speed of the saw 01100 Vcl750 -> the circular speed of the saw 01750 nllOO -> the number of the circulations of the saw 01100 nl750 -> the number of the circulations of the saw 01750 = πxDxn/60xl000 -> n = Vςx60xl000/IIxD nllOO = 63x60x1000/3.14x1100 nllOO ~ 1094 d/d has to be. nl750 = 55x60x1000/3.14x1750 nl750 ~ 600 d/d is found.

As seen above, in order to obtain the ideal peripheral speeds, the circulations of the saws have to be very different from each other. Through the invention that we have created basing on the datum above, with a single impulse, the circulations we want can be obtained through two different belts and wheels. For sampling; the configuration of the wheel that performs the conditions above is such;

For the wheel that is connected to the engine (8) ; For the saw 01100, a double-degree wheel having a diameter of 0285mm For the saw 01750, a double-degree wheel that has a diameter of 0220mm has to be chosen.

The wheels those are connected with the hive (4)

For the saw 01100, a wheel of 0258 mm

For the saw 01750, a wheel of 0362 mm

The diameters of the wheels given above are calculated just for the aim of sampling. The wheel diameters may vary in accordance with the cutting speeds that vary according to the structure and hardness of the marble or natural stone.

As a result of the connection of the cutting saws (34, 38) at different dimensions on the same hive (4) , all the disadvantages that affect the cutting capacity are eliminated and among the similar systems that carry out the same work, a great success is obtained at capacity, fertility and the cost of the foundation.

The hive system (4) according to the present invention comprises a main saw crowbar (22) that enables the cutting parts (34, 38) to move at different circulations, which is positioned in a telescopic way on the same axis, an inner hive (16) that covers the said main saw crowbar (22) allowing its movement. To allow the rotating movements of the inner hive (22) that has the quality of rotating at different circulations and the main saw crowbar (22) , the saw wheels (27, 29) are positioned.

To fix and lay the cutting parts (34, 38) on the said inner hive (16) and the main saw crowbar (22) , the small saw flange (32) and the main saw flange (36) are positioned. Also, to fix the cutting parts (34, 38) on the inner hive (16) and the saw crowbar (22), the saw fixing flange (35) and the main saw fixing flange (44), and a main saw hive (10) where the said inner hive (16) and main saw crowbar (22) are positioned and which covers both two parts from the outside is positioned.
