Description
Technical Field
The present invention relates to stone machining methods and apparatus, and more particularly to methods and apparatus for machining stone by sawing.
Background
The stone block is mined from a mine and then cut into boards, strips or block semi-finished products for subsequent processing. Cutting of stone blocks is currently performed by means of circular saws, wire saws and reciprocating wire saws. However, the cutting method still has various limitations on key problems such as cutting of large-size rough materials, cutting of hard and brittle stones, outturn rate of rough materials, machining efficiency, service life of cutters and the like. At present, the cutting method of the rough stone material is mainly four: (1) the swing type steel sand grinding and cutting method and the granite swing type steel sand saw equipment developed according to the method are generally used for processing granite plates with Mohs hardness of more than 5 degrees due to lower efficiency; the method utilizes the impact grinding of the saw blade and the prismatic steel sand to the granite material to realize the slitting function, which is the present large-scale granite plate slitting process equipment with the most use amount. (2) The wire saw rotary cutting method and the wire rope bead saw developed according to the method are recommended to be used in developed countries such as Europe and America in recent years, namely a certain amount of diamond cylindrical cutters are fixed on an annular thin wire rope, stone is cut by utilizing continuous high-speed rotation of the wire rope, and the process equipment has the advantages of simple structure and high cutting efficiency due to the fact that the very sharp diamond cutters are used. (3) The circular saw rotary cutting method and the circular saw blade sawing equipment developed based on the method adopt a large-diameter diamond circular saw blade rotating at a high speed to cut stone materials, and due to the limitation of the diameter of the saw blade, when the saw blade with the maximum diameter of 3000mm is used, only plates with the width size smaller than 1200mm can be processed, the surface quality of the plates is poor, and the problem that the saw gap is larger than 8mm also exists. The two sawing methods are characterized in that the continuous rotation scheme of the cutter is used, and the diamond cutter bears in one direction, so that the two sawing methods have the characteristics of high efficiency and long service life of the cutter; the defects of large saw kerf, low outturn rate and resource waste. (4) The cutting method of the reciprocating motion of the straight-line saw and stone gang saw machine developed according to the method, but the existing stone gang saw machine is generally only used for processing marble, limestone and other stones with Mohs' hardness of less than 5 degrees, the required cutting force is larger for granite, quartz, jade and the like with higher hardness, when the cutter teeth of the diamond saw blade of the existing stone gang saw machine reciprocate, the welding strength and the steel band saw blade are difficult to bear reciprocating alternating load, so the stone gang saw machine is not popularized and used; another reason that the cutting efficiency of the existing stone gang saw machine is low is that the linear velocity of the cutter is too low, the reciprocating motion mechanism of the crank connecting rod is adopted, the cutter is influenced by a saw frame with large mass, the reciprocating velocity is difficult to improve, the sawing frequency in unit time is less, the speed of the reciprocating cutter is not uniform, when the saw frame is reversed, the linear velocity is 0, stone continuously fed can form huge positive pressure on the cutter, and the effective use of the cutter is not facilitated.
In the Chinese patent database, the application parts related to stone sawing are as follows: 931096472 method for sawing thin stone sheets/plates from stone, ZL942367928 method for sawing reciprocating stone, ZL02206849X stone, 2011101016766 method for sawing novel stone, ZL2015105285030 chain saw cutter, 2015101208459 chain saw cutter, 2017111390531 method for cutting arc and oval profiles of stone by using circular saw, etc., which can not process granite plates by the unidirectional movement of saw blade and can not overcome the defects of the existing various cutting methods.
Disclosure of Invention
The invention aims to provide a stone sawing method with a saw blade rotating unidirectionally and continuously, which realizes the unidirectional movement of the saw blade to process granite plates, thereby overcoming the defects of various cutting methods.
The invention also aims to provide a stone plate gang saw machine with a rotary saw frame, which realizes a stone sawing method with a saw blade rotating in a unidirectional and continuous manner.
The inventor finds in practice that: the key point for overcoming the defects of various cutting methods is to solve the alternating stress condition of the saw blade of the stone gang saw machine, realize the unidirectional movement of the saw blade to process granite plates, greatly improve the stress condition of the diamond cutter teeth of the saw blade, and adopt the diamond cutter manufactured by the latest technology, thereby reducing the thickness of the saw blade, and changing the conditions of large saw gap, low efficiency and high energy consumption of the existing high-hardness stone sawing. And for marble stone with lower hardness, the service life of the saw blade is greatly prolonged, and the use cost is reduced.
Therefore, the stone sawing method with the saw blade rotating in a single direction and continuously provided by the inventor is a saw frame continuous rotating device using a double-crank quadrilateral mechanism principle, wherein a connecting rod of the saw frame continuous rotating device using the double-crank quadrilateral mechanism principle is a saw frame for mounting the saw blade; the main crank rotates continuously under the driving action of the power system to drive the driven crank to rotate synchronously, so that the saw frame is driven to do circular translation motion. When the rotary saw frame reaches a certain quadrant point in the feeding direction of the stone material, the group of saw blades in the saw frame collide with the stone material, the potential energy of the continuous rotary device of the saw frame does work to form a milling action, and therefore the stone material is cut; when the rotary saw frame leaves the stone, the continuous rotary device of the saw frame continuously rotates to store energy for the next period of milling action.
The double-crank quadrilateral mechanism can be a parallelogram link mechanism with equal length of the driving crank and the driven crank which are preferentially used, and can also be a quadrilateral link mechanism with different lengths of the driving crank and the driven crank.
The driving power of the double-crank quadrilateral mechanism is arranged at the end of the driving crank, and when the saw blades are more, the driving power system capable of synchronously rotating is arranged at the end of the driving crank and the end of the driven crank.
The continuous rotation speed of the double-crank quadrilateral connecting rod saw frame is not lower than 100r/min when the double-crank quadrilateral connecting rod saw frame works, and the length of the driving crank is not lower than 50 mm.
The invention provides a saw frame rotary stone slab gang saw machine which is vertical and horizontal and comprises a power system, a circular translation link mechanism saw frame device and a stone raw material feeding device.
The power system consists of a motor, a transmission belt, a driving wheel, a driving shaft, a driven wheel, a driven shaft and a synchronous connecting rod, wherein the motor, the transmission belt, the driving wheel and a driving crank are arranged above the vertical saw frame rotary stone slab gang saw machine, the driven wheel and a driven crank are arranged below the vertical saw frame rotary stone slab gang saw machine, and the synchronous connecting rod connects the driving wheel and the driven wheel to run synchronously; the tail ends of the driving crank and the driven crank are connected with the saw frame.
The saw frame of the circular translation link mechanism uses the principle of a double-crank quadrilateral mechanism, the saw frame device consists of a saw frame and saw blades, two ends of the saw blades are respectively fixed at the upper end and the lower end of the saw frame, a plurality of groups of parallel saw blades are arranged in the saw frame, and the saw teeth on the saw blades are made of high-hardness diamond materials.
The stone block feeding device mainly comprises a stone trolley, wherein the stone block is fixed on the stone trolley and moves along the direction parallel to the rotation track of the circumferential translation link mechanism type saw frame device at a set speed under the action of a driving system to realize milling feeding, and can also quickly and reversely move along the feeding track to realize tool withdrawal and return to the initial position; the driving shaft and the driven shaft are provided with fan-shaped deflection weight parts. Under the action of a driving system, the driving crank of the double-crank quadrilateral mechanism drives the diamond sheet saw blades arranged in parallel in the saw frame to do rotary motion, and the driven crank of the double-crank quadrilateral mechanism synchronously rotates along with the main crank to keep the diamond sheet saw blades arranged in parallel in the saw frame to do translational motion.
The driving crank and the driven crank are respectively one and are arranged on one side of the saw frame; when the saw blade is more, the 2 cranks with the axes in the same straight line can also be respectively arranged at the two sides of the saw frame.
The operation principle of the saw frame rotary stone slab gang saw machine is as follows: the device is a device for continuously rotating a saw frame according to a double-crank quadrilateral mechanism, and a connecting rod of the device is the saw frame for mounting a saw blade. The main crank rotates continuously under the driving action of the power system to drive the driven crank to rotate synchronously, so that the saw frame is driven to do circular translation motion. When the rotary saw frame reaches one of the quadrant points in the feeding direction of the stone material, the group of saw blades in the saw frame collide with the stone material, the potential energy of the continuous rotary device of the saw frame does work to form a milling action, and therefore the stone material is cut; when the rotary saw frame leaves the stone, the continuous rotary device of the saw frame continuously rotates to store energy for the next period of milling action.
The inventor points out that: the double-crank quadrilateral mechanism can be a parallelogram link mechanism with equal length of a driving crank and a driven crank which are preferentially used, and can also be a quadrilateral link mechanism with different lengths of the driving crank and the driven crank; the driving power of the double-crank quadrilateral mechanism can be arranged at the end of the driving crank, and when the saw blades are more, the driving power system capable of synchronously rotating can be arranged at the end of the driving crank and the end of the driven crank.
The operation process of the saw frame rotary stone slab gang saw machine is as follows: the motor drives the driving wheel to rotate through the transmission belt, the driving wheel drives the driving crankshaft to rotate, the driving crankshaft drives the saw frame to rotate, the other 3 crankshafts rotate in a follow-up manner, and the saw frames connected to the driving shaft and the follow-up shaft synchronously rotate under the assistance of the synchronous connecting rod, so that the parallel rotation action is realized; the driving wheel drives one end of the crankshaft to rotate along the center of the bearing seat, and the other end of the crankshaft drives the saw frame to rotate by the designed eccentricity. The stone trolley moves oppositely at a low speed along the direction parallel to the motion trail of the diamond saw blade through the feeding driving device, and the saw blade rotates at a high speed under the drive of the saw frame. The cutting amount of the saw blade is as follows: the translation feeding amount of the trolley within the rotation time of the saw blade every time; each cut of the saw blade is completed only in a very short time in contact with the stone, and when the saw blade is rotated backward, the saw blade does not have any cutting impact with the stone. The diamond saw teeth are distributed at intervals, so that the profile of the cutting surface of the stone material is formed by continuously forming circular arc line segments instead of a straight line according to the size of the rotation circle of the saw blade. The eccentric balance weight arranged on the crankshaft is used for balancing the eccentric torque of the saw frame, so that basic dynamic balance is realized, the weakening of the service life of a bearing caused by the fact that the center of gravity deviates from the rotating axis is reduced, meanwhile, the eccentric balance weight and the centrifugal inertia generated by the saw frame during rotation effectively assist in resisting the cutting resistance of a saw blade, and the energy consumption is reduced. The saw blade in the saw frame cuts the stone block into thin plates with specified thickness, and the thin plates are ground and cut off to obtain the building stone plate with good decorative effect.
The stone sawing method with the saw blade rotating unidirectionally and continuously overcomes the fatal defect that the sawteeth of the existing stone gang saw machine are subjected to alternating fatigue stress to cause quick falling, greatly increases the cutting efficiency, and reduces the maintenance cost and the labor loss. It is suitable for processing various stone materials into thin plates.

Fig. 4 and 5 are schematic diagrams of a vertical stone slab gang saw machine using the stone sawing method of the invention. As shown in fig. 4, the vertical gang saw machine comprises a saw frame device of a vertically placed circumferential translation connecting rod 7 and a stone raw material horizontal feeding device 13, wherein the axes of a main crank 8 and a driven crank 9 of the circumferential translation connecting rod mechanism type saw frame device are arranged in the same vertical plane, under the action of a driving power system 5, diamond sheet saw blades 11 which are arranged in parallel in the saw frame of the connecting rod 7 perform vertical translation and rotation movement and form relative movement with the stone raw material 6 which is continuously fed in the horizontal direction, so that the stone is milled; the stone block feeding device 13 comprises a block trolley 14, a follow-up trolley 15, a traction trolley 16 and a conveying roller 15, one end of the stone block 6 is fixed on the block trolley 14 and the follow-up trolley 15, the other end of the stone block is erected on the conveying roller 17 right below the saw frame, the stone block is driven by the block feeding device 13 to continuously roll and feed along the horizontal direction, and the stone block is dragged by the traction trolley 16 after passing through the saw frame until the whole stone block traverses the saw frame and is cut into thin plates with set thickness. In fig. 5, a synchronous connecting rod 10 is also adopted, when the main crank 8 and the driven crank 9 synchronously rotate to the quadrant point, the driven crank 9 can turn to an unfixed point once, and the synchronous connecting rod 10 drives the driven crank 9 to smoothly pass through the unfixed point, so that the unidirectional translation continuous motion of the diamond saw blade 11 is realized.
Fig. 6 and 7 are schematic diagrams of a horizontal type stone slab gang saw machine using the stone sawing method of the invention. As shown in fig. 6, the horizontal gang saw machine comprises a horizontally arranged circular translation link mechanism type saw frame device 7 and a stone raw material lifting and feeding device 18, wherein the axes of a driving crank 8 and a driven crank 9 of the circular translation link mechanism type saw frame device 7 are arranged in the same horizontal plane, and under the action of a driving power system 5, diamond sheet saw blades 11 which are arranged in parallel in the saw frame of the link mechanism 7 perform left-right translation and rotation movement and form relative movement with the stone raw material 6 which is continuously fed in the vertical direction, so that the stone material 6 is milled; the stone block lifting and feeding device 18 comprises a block trolley 14 and a trolley driving system 13, wherein the stone block is fixed on the block trolley 14, and continuously ascends and feeds along the vertical direction under the action of the trolley driving system 13 until the whole stone block 6 vertically passes through the connecting rod 7 saw frame and is cut into thin plates with set thickness. In fig. 7, a synchronous connecting rod 10 is also adopted, when the driving crank 8 and the driven crank 9 synchronously rotate to the quadrant point, the driven crank 9 can turn to an unfixed point once, and the synchronous connecting rod 10 drives the driven crank 9 to smoothly pass through the unfixed point, so that the diamond saw blade 11 can move continuously in the same direction in a translation manner.
The two kinds of frame-sawing rotary stone slab gang saws illustrated in fig. 4 and 5, and fig. 6 and 7 both realize the circular translation motion of the connecting rod saw frame, so that the thin saw blades in the saw frame only bear the unidirectional cutting load. Because the saw gap is smaller, the sawing yield of the hard and brittle stone is improved, and the energy consumption is reduced. Furthermore, the stone slab gang saw machine of the two embodiments of the invention adopts the circular translation link mechanism type saw frame device, and the rotating centrifugal force of the large-mass saw frame can be reduced by the corresponding balancing weight, so that higher rotating speed can be obtained, the saw blade is ensured to be always in milling contact with the stone rough material at the highest linear velocity, the saw blade pressure in the period of lower linear velocity of the gang saw machine in the traditional technology is avoided, and the service life of the saw blade is prolonged.
