Description

Technical field:

[0002] The invention relates to a high-efficiency energy-saving stone cutter and a working method thereof. Background technology:

[0004] A stone cutter is used for cutting stone. Currently, there are bridge-type or cantilever-type stone cutters. Although a stone cutter is a very mature mechanical equipment, it still has some problems: 1. When starting the spindle on which the stone cutting saw blade is installed, a large torque is required, so that the current of the starting motor is 5-6 times that of normal operation, which consumes a lot of energy and brings huge load pressure to the factory's electrical equipment, and also increases the construction cost of electrical equipment; 2. After the cutting saw blade processes a piece of stone rough material, it needs to be stopped to replace a new stone rough material, so it needs to be started and stopped repeatedly, which also increases the energy consumption of starting; 3. When cutting stone, it is necessary to continuously spray water on the tool and stone to avoid the phenomenon of burning the knife caused by excessive cutting temperature. At present, a water cover is usually covered on the cutting saw blade, and a water pipe with continuous water spraying is inserted into the water cover. The water cover serves to cover the splashing water and flying powder, but when the cutting saw blade is worn or damaged, it is necessary to stop the machine and replace the cutting saw blade. Because the water cover is relatively fixed to the spindle, the water cover must be disassembled and installed every time the cutting saw blade is replaced, which increases the replacement time.

[0042] The method of the present invention is further described in detail below in conjunction with the embodiments. It should be particularly noted that the protection scope of the present invention should include but is not limited to the technical content disclosed in this embodiment.

[0043] The high-efficiency and energy-saving stone cutting machine of the present invention comprises a machine platform A1 and a machine base A2 arranged on the machine platform A1, the machine base A2 is provided with a main shaft A4 for driving a stone cutting saw blade A3 to rotate, the main shaft A4 is provided with a pulley A5, a clutch A6 is provided inside the pulley A5, an active part A7 of the clutch is connected and fixed to the pulley A5, a driven part A8 of the clutch is connected and fixed to the main shaft A4, a clamping mechanism A9 for driving the active part and the driven part to engage and disengage is also provided on the clutch, a motor B and a pulley transmission mechanism B1 driven by the motor are provided on the machine base, and the pulley transmission mechanism B1 transmits power to the pulley A5 on the main shaft.

[0044] In the bridge-type stone cutting machine, the machine base A2 is two vertical seats arranged on the machine platform, a beam D is horizontally arranged on the two vertical seats, a slide D6 is slidably arranged on the beam D, the spindle A4 is installed on the spindle box, and the spindle box and motor B are installed on the slide D6; in the cantilever stone cutting machine, the spindle A4 is installed on the spindle box, and the spindle box and motor B are installed on the lifting seat A26 which can be raised and lowered on the cantilever A25.

[0045] Before work, the motor does not work and the clamping mechanism does not drive the clutch, so that the active part and the driven part of the clutch are in a disengaged state. During work, the motor starts working first, driving the pulley transmission mechanism and the pulley to rotate, and then the clamping mechanism drives the active part and the driven part from a disengaged state to a coupled state, and then drives the main shaft equipped with the stone cutting saw blade to start rotating, thereby transmitting the power of the motor to the main shaft. Since the clamping mechanism gradually clamps the active part and the driven part from a disengaged state to a coupled state, that is, the transmission of power is also a process, the previous problem of instantaneous high load will not occur.

[0046] The pulley transmission mechanism B1 includes a driving pulley fixed on the motor output shaft, and a belt A27 connected between the driving pulley and the pulley A5. The belt can be a V-belt, a parallel belt or a trapezoidal belt.

[0047] The above-mentioned clutch can be a friction clutch, a hydraulic clutch, an electromagnetic clutch, etc., wherein the clamping mechanism is a mechanism in the clutch that drives the active member and the driven member to separate and engage. The specific clutch structure of this application is described below.

[0048] The pulley A5 comprises a cover-shaped wheel shell A10 having a pulley groove on its outer surface, and an active member A7, a driven member A8 and a clamping mechanism A9 covered in the cover-shaped wheel shell, wherein the active member and the driven member are a plurality of adjacently arranged circular active friction plates A11 and driven friction plates A12, wherein the outer periphery of the active friction plate A11 is provided with an outer convex tooth A13, and the periphery of the center hole of the driven friction plate A12 is provided with an inner concave tooth A14, and the shaft section of the main shaft A4 extending into the clutch is provided with a spline A15 corresponding to the inner concave tooth A14, and the inner peripheral wall of the cover-shaped wheel shell A10 is provided with a keyway A16 (the shape of the keyway A16 can be Rectangular, trapezoidal, etc.), the active friction plate and the driven friction plate can both move axially along the main shaft, that is, the active friction plate A11 and the driven friction plate A12 can slide on the shaft section of the main shaft A4 extending into the clutch and the cover-shaped wheel shell A10 (that is, the circular inner hole of the active friction plate is required to be larger than the outer diameter of the spline A15, and the circular outer edge diameter of the driven friction plate A12 is smaller than the inner circumferential wall of the cover-shaped wheel shell A10), and the clamping mechanism is at least one hydraulic cylinder (this application uses 6 evenly distributed around the circumference) provided on the side of the active friction plate and the driven friction plate. Through the extension of the hydraulic cylinder, each active friction plate and the driven friction plate can be pressed to generate friction, and the tighter the compression, the greater the friction force.

[0049] When the clamping mechanism drives the active member and the driven member to move from a disengaged state to a coupled state, the hydraulic cylinder extends, causing the adjacent active friction plates and driven friction plates to approach each other and generate friction, so that power is transmitted from the cover-shaped wheel shell to each active friction plate, each active friction plate to each driven friction plate, and each driven friction plate to the main shaft, thereby realizing the rotation of the main shaft.

[0050] The cover opening of the above-mentioned cover-shaped wheel shell is provided with a cover cover A17, and the cover cover is provided with a plurality of bearing groove holes A18, each bearing groove hole receives a stepped hydraulic cylinder housing A19, and the telescopic rod A20 of each hydraulic cylinder is pressed against the side of the active friction plate and the driven friction plate, and a support plate A21 can be provided on the side to make the thrust more uniform, and the hydraulic pipeline A24 of each hydraulic cylinder is connected in series and connected to the hydraulic main pipe A22 extending into the cover cover, and the hydraulic main pipe A22 penetrates from the central part of the removable cover plate A23 on the cover cover A17, and is hinged to the removable cover plate A23 of the cover cover A17, so that the hydraulic main pipe A22 will not rotate with the cover cover A17.

[0051] The high-efficiency and energy-saving stone cutting machine of the present invention has a clutch installed in the pulley on the main shaft. The clutch gradually develops from a clutch state to a clutch state, so that the force transmitted to the main shaft and the cutting saw blade on the main shaft by the motor is gradually increased, thereby avoiding the large current required for instantaneous starting of the motor, which is beneficial to reducing the load of electrical equipment, reducing construction costs, and greatly reducing energy consumption.

[0052] Furthermore, in order to save energy and reduce consumption, the above-mentioned motor is a high-low dual-power motor. The high-low dual-power motor C includes a casing C1 and a motor shaft C2 arranged in the casing. The motor shaft has two independent rotor windings C3. The casing is provided with a stator winding C4 corresponding to the two independent rotor windings. The two independent rotor windings C3 and stator windings C4 output high and low power respectively. The high-power rotor windings C3 and stator windings C4 are wound with more coils, and the low-power rotor windings C3 and stator windings C4 are wound with fewer coils. Of course, the motor that can output high and low dual power can also be an existing dual-power motor with other structures.

[0053] When the motor is started, the low-power windings of the motor work first, and then the high-power windings work. Then the clamping mechanism drives the active and driven parts from a disengaged state to a coupled state, and then drives the main shaft with the stone cutting saw blade to start rotating. When cutting stone, the high and low power parts of the motor work at the same time. When not cutting stone, only the low power part works to maintain the rotation speed of the main shaft and the stone cutting saw blade.

[0054] Through the above-mentioned motor working method, the current required for starting work can be reduced, the load pressure on electrical equipment can be reduced, the construction cost can be reduced, and energy saving and consumption reduction can be achieved; and when cutting with an empty knife, only a low-power motor is used to work, which reduces energy consumption.

[0055] At present, the main beam of the bridge-type stone cutter is made of steel as a whole, which is not only costly but also difficult to manufacture.

[0056] The present application provides a beam D on the machine base A2 (the beam D is only provided on the bridge-type stone cutting machine), and the beam D includes a closed metal outer shell D1 and a gel body D2 filled in the metal outer shell and solidified. The gel body D2 can be a polymer material such as plastic and resin, which is filled into the closed metal outer shell in a molten state and formed after solidification.

[0057] In order to achieve reasonable design and high strength, the gel is mixed with iron ore D3, and steel bars D11 are arranged in the gel. The iron ore is evenly mixed in the gel, and the volume of the iron ore accounts for 10-60% of the inner volume of the metal outer shell D1. The steel bars can be cross-bound horizontally and vertically to form a column cage shape.

[0058] Furthermore, in order to realize the movement of the spindle box on which the spindle is installed, the upper wall surface of the above-mentioned metal outer shell D1 is provided with two parallel guide rails D4 and a rack D5 arranged between the two guide rails. The spindle box is installed on a sliding seat, and the sliding seat D6 slides in cooperation with the guide rails, and a gear driven by another motor and meshing with the rack is provided on the sliding seat.

[0059] Furthermore, for the sake of reasonable design, the above-mentioned metal outer shell D1 includes an upper wall plate D7, a lower wall plate D8 and symmetrically arranged two side wall plates D9, and the middle part of the lower wall plate and the two side wall plates has an inner recess D10 that runs through the beginning and the end, and the cross-section of the inner recess is rectangular or trapezoidal.

[0060] The beam of the present application has the advantages of large load-bearing weight and good impact resistance, especially in stone cutting, it can resist deformation and improve stone cutting accuracy and work efficiency.

[0061] Furthermore, in order to facilitate the disassembly and assembly of stones without affecting the cutting process, the above-mentioned machine is provided with a support seat E1 for carrying the stone to be cut. The support seat E1 includes a slide seat E2 that can slide along the slide rail on the machine and a rotating table E3 arranged on the slide seat, and the stone to be cut is placed on the rotating table.

[0062] Furthermore, in order to reduce vibration, a rubber pad E4 is laid on the upper surface of the rotating table, and the stone to be cut is placed on the rubber pad. By setting the rubber pad E4, when the cutting saw blade is still cutting other stones on the rotating table E3, moving the cut stone will not affect the cutting process, which is conducive to ensuring the cutting quality.

[0063] The above-mentioned rotating table E3 can be a flat plate body, the bottom surface of the slide E2 has a guide groove, and the machine platform has a slide rail. The slide E2 can be driven to slide along the length direction of the slide rail by a screw nut mechanism, a synchronous belt and other mechanisms. The upper surface of the slide E2 is a plane, and a plane thrust bearing can be provided between the slide E2 and the rotating table E3 to realize the rotation of the two, and the rotation power of the rotating table E3 can be driven by a steering gear.

[0064] Furthermore, for the sake of reasonable design, the rubber pad is a long strip with a rectangular cross section, and a plurality of rubber pads are laid on the upper surface of the rotating table, with spacing between adjacent rubber pads.

[0065] The rubber pad is provided with at least one stone block close to and far from the cutting saw blade (two blocks are shown side by side in the figure). The cutting work is only for the stone block close to the cutting saw blade, and the stone block far from the cutting saw blade is a preparation material. That is, after the cutting of the stone block close to the cutting saw blade is completed, the cutting saw blade and the support seat return to the original position, the cutting saw blade continues to rotate, the rotary table rotates 180 degrees, the stone block far from the cutting saw blade becomes close to the cutting saw blade, and the stone block can be processed. The cut stone block can be removed from the support seat and replaced with a new stone block to be processed. When replacing the material, the rubber pad can buffer the vibration generated when replacing the stone block to avoid affecting the cutting quality. The structure of the rotary table E3 and the like can replace the stone without stopping the machine, which greatly improves the efficiency and reduces the energy consumption of repeated shutdown and startup, killing two birds with one stone.

[0066] Furthermore, for the convenience of use, the above-mentioned machine base is provided with a water cover F1 that can be raised and lowered relative to the stone cutting saw blade on the main shaft. The above-mentioned lifting water cover is driven to rise and fall by an oil cylinder F2 arranged on the machine base A2 (for the bridge-type stone cutting machine, it is specifically the slide seat D6, and for the cantilever-type stone cutting machine, it is the lifting seat A26). Of course, the water cover can also be driven to rise and fall by a nut screw mechanism, a cylinder, etc. The water cover F1 can be raised and lowered, which is convenient for lifting when it is necessary to replace the worn or damaged cutting saw blade, thereby eliminating the need for manual disassembly and assembly, thereby improving efficiency.

[0067] In addition, the current position of the water cover and the main shaft is relatively fixed. The stone cutting saw blade cuts from the upper surface of the stone rough material to the lower surface. Since the cutting saw blade can only cut to a position below the lower end point of the main shaft, the lowest point of the water cover must be higher than the lower end point of the main shaft to ensure that the water cover will not interfere with the stone during the entire cutting process. However, under the current water cover with this structure, some water and stone powder will still splash during the entire cutting process.

[0068] When the stone cutting saw blade just starts to cut from the upper surface of the stone rough material, the oil cylinder drives the water cover to make the water cover closest to the lower end point of the stone cutting saw blade. As the stone cutting saw blade moves from top to bottom, the oil cylinder drives the water cover to gradually move away from the lower end point of the stone cutting saw blade. The lowest point of the water cover of the present application can pass below the main shaft axis and can reach a saw blade radius of two-thirds of the lower end point of the stone cutting saw blade, thereby further improving the existing effect of shielding splashing water and stone powder.

[0069] Therefore, the liftable water cover F1 of the present application can change the area of ​​shielding the saw blade according to different processing positions, thereby improving the effect of shielding splashing water and stone powder, while facilitating the disassembly and assembly of the cutting saw blade, thereby improving efficiency.

[0070] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.

That is, after the cutting of the stone block close to the cutting saw blade is completed, the cutting saw blade and the support seat return to the original position, the cutting saw blade continues to rotate, the rotating table rotates 180 degrees, the stone block far from the cutting saw blade becomes close to the cutting saw blade, and the stone block can be processed, and the stone block that has been cut can be taken off the support seat and replaced. When a new stone block to be processed is put on, the rubber pad can buffer the vibration generated when the stone block is replaced to avoid affecting the cutting quality; a water cover is provided on the machine base, which is lifted and lowered relative to the stone cutting saw blade on the main shaft, and the lifted water cover is driven and lifted by an oil cylinder provided on the machine base, and the stone cutting saw blade saws from the upper surface to the lower surface of the stone block. When the stone cutting saw blade just starts to cut from the upper surface of the stone block, the oil cylinder drives the water cover to make the water cover closest to the lower end point of the stone cutting saw blade, and as the stone cutting saw blade moves from top to bottom, the oil cylinder drives the water cover to gradually move away from the lower end point of the stone cutting saw blade.
