Description

Technical Field

[0001] The utility model relates to the technical field of wire saws, in particular to a novel wire saw. Background Art

[0002] Marble looks very beautiful after being polished. It is mainly used to be processed into various shapes and plates for the walls, floors, platforms and columns of buildings. It is also often used as a material for memorial buildings such as monuments, towers and statues. Marble can also be carved into arts and crafts, stationery, lamps, utensils and other practical art products.

[0003] When cutting large pieces of marble, a pull saw is generally used for cutting. When using a pull saw for cutting, the pull saw makes a reciprocating motion, and the large buried stone slowly rises. The saw blade is usually thick, usually 3 to 5 mm. This cutting method is not only slow in cutting speed, but also produces thick marble slices after cutting, and has low cutting efficiency. It also causes a waste of raw materials, obvious knife marks on the surface of the marble, and subsequent surface processing is more complicated. When using a wire saw for cutting, the existing usage method is mostly to fix the marble and use a wire saw with diamond wire to move up and down for cutting. Since the diamond wire is relatively soft, it is easy to deflect during cutting, resulting in cutting errors. Therefore, this technical solution is proposed for improvement. Utility Model Content

[0006] Furthermore, the bottom of the mounting frame is fixed on the base, and the lifting frame includes a screw rod arranged at the bottom of the mounting frame, and the screw rod is provided with four ends respectively connected with the four corners of the lifting frame.

[0007] Furthermore, the screw rods rotate synchronously through a connecting device.

[0008] Furthermore, an inspection platform is provided in the middle of the mounting frame, and a staircase is provided on one side of the inspection platform.

[0009] Furthermore, both ends of the roller are provided with bearing seats connected to the mounting frame, one end of the roller is provided with a driving motor, the installation position of the roller is rectangular, and the two rollers below the cutting part are arranged inside the mounting platform.

[0010] Furthermore, a protective plate is provided on the side of the roller.

[0011] Furthermore, a wire-taking device is provided on the inner side of the protective plate, and the wire-taking device includes a wire roller, and the wire roller is connected to a motor, and the wire roller is arranged parallel to the roller. An adjusting wheel and a tightening wheel are also provided above the wire roller, and the tightening wheel is connected to a tightening motor, and a rocker arm is provided at the output end of the tightening motor and connected to the tightening wheel.

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] See also Figures 1 to 5 The embodiment of the utility model discloses a new type of wire saw, which is mainly composed of a mounting frame 1, a lifting frame 3, a cutting part, a base, an inspection platform 101 and an auxiliary device. The mounting frame 1 serves as the supporting frame of the entire equipment and is welded with high-strength steel to ensure a stable structure. When in use, a base can be set at the bottom of the mounting frame 1. The base can be a cement or metal base, which can be installed according to the use environment, and a plurality of guide grooves are opened on the upper surface of the base to drain the coolant and residue during the cutting process, thereby improving stability and use effect.

[0022] The bottom of the mounting frame 1 is designed as an open frame, which is convenient for maintenance and observation of the cutting process. The top and bottom are provided with reinforcing ribs to enhance the overall rigidity and ensure that the mounting frame 1 is installed horizontally during installation. A horizontal mounting surface is provided on the upper part of the mounting frame 1 for installing cutting components such as rollers 2. A cutting part is provided on the upper part of the mounting frame 1 for cutting marble. The cutting part consists of four rollers 2 parallel to each other. The installation positions of the rollers 2 are arranged in a rectangular layout. The two rollers 2 at the bottom are arranged inside the inspection platform 101 to improve the compactness of the equipment. A plurality of precisely machined grooves are provided on the surface of the rollers 2 to accommodate and guide the diamond wire for cutting, thereby forming an effect of simultaneous cutting of multiple working surfaces and improving cutting efficiency. The distance between the upper roller 2 and the lower roller 2 is large to prevent the upper diamond wire from affecting the cutting effect after the marble is cut by the lower diamond wire, thereby ensuring safety in use and improving production quality. A protective plate 103 is set on the side, and the protective plate 103 can be removed to prevent debris generated during the cutting process from splashing and injuring people, while protecting the roller 2 from external interference to ensure production safety. A wire taking-up device is installed inside the protective plate, including a wire roller 4, which is connected to a motor. The wire roller 4 is arranged horizontally, and the diamond wire is wound on the wire roller 4. An adjusting wheel 401 and a take-up wheel are also arranged above the wire roller 4. The take-up wheel 403 is connected to a take-up motor 402, and the take-up motor 402 drives the rocker arm 404 to swing to achieve the tensioning and relaxation of the diamond wire. The adjusting wheel is connected to a telescopic rod, and the tensioning degree of the diamond wire is adjusted by adjusting the length of the telescopic rod in conjunction with the take-up wheel. The adjusting wheel 401 keeps the output direction of the diamond wire stable, and the take-up wheel 403 adjusts the tensioning degree of the diamond wire by adjusting the relative position. The diamond wire is tightened by the cooperation of the adjusting wheel and the take-up wheel, and the auxiliary roller keeps the diamond wire running stably.

[0023] At the same time, standing on the inspection platform 101 can also increase the operating space. The stairs 102 on one side are convenient for people to go up and down, and the entire mounting frame 1 and the inspection platform 101 can be selected in different sizes according to different marble production specifications. The four rollers 2 are equipped with drive motors 201 to provide sufficient power for the diamond wire to ensure production results.

[0024] The two ends of the roller 2 are mounted on the mounting frame 1 through the bearing seat 202, and one end is connected to the drive motor 201. The high-speed rotation of the roller 2 is achieved through the bearing seat 202 to ensure the stability of use. The bearing seat 202 includes a shell 203. A cooling system for cooling the bearing and the rotating shaft 204 at both ends of the roller 2 is provided inside the shell 203. The rotating shaft 204 passes through the bearing seat 202. The rotating shaft 204 is provided with two sets of bearings 205 at both ends of the bearing seat 202 and is rotatably connected to the bearing seat 202. A blocking plate 206 is provided on the outside of the bearing 205. A spacer 208 is provided on the rotating shaft 204 between the two sets of bearings 205. A copper sleeve 207 is provided on the outer side of the spacer 208. A cooling chamber is provided between the copper sleeve 207 and the spacer 208. Convex ridges facing the spacer 208 are provided at both ends of the copper sleeve 207. A gap is left between the ridges and the outer wall of the spacer 208. Four through holes are provided on the outer wall of the copper sleeve 207. An oil inlet connector 2031 connected to the pump station is provided on the top of the bearing seat 202. A flow channel 209 is provided at the bottom of the bearing seat 202. The inlet of the flow channel 209 is provided at the plug. Between the plate 206 and the bearing, the outlet of the flow channel 209 is connected to the cooling box of the pump station through a pipeline. When the roller 2 rotates at high speed, high temperature is generated between the rotating shaft 204 of the roller 2 and the bearing seat 202. The hydraulic oil cooled by the cooling box in the pump station passes through the oil inlet joint 2031 on the top of the bearing seat 202 and abuts against the outer wall of the copper sleeve 207, and enters the cooling chamber through the four through holes on the outside of the copper sleeve 207. Under the action of oil pressure, the copper sleeve 207 is pushed outward, and the cooled hydraulic oil forms a stable support inside the cooling chamber, reducing the rotating shaft 20 During the rotation process, the hydraulic oil flows to the bearing 205 through the gap between the copper sleeve 207 and the spacer 208. The blocking plate 206 prevents the hydraulic oil from leaking out. The hydraulic oil that leaks out of the bearing flows into the flow channel 209 and flows to the bottom of the bearing seat 202 under the action of gravity and pressure. A circulation is formed through the pipeline to complete the cooling of the rotating shaft 204 and the bearing 205 of the roller 2, preventing the bearing 205 and the rotating shaft 204 from deformation or jamming under high-speed rotation, thereby ensuring the use effect, extending the service life, and reducing the failure rate.

[0025] The lifting frame 3 is located at the bottom of the mounting frame 1 and is used to carry and stabilize the marble body to be cut. The lifting frame 3 is driven by four screw rods 301 vertically arranged at the bottom of the mounting frame 1. The motor's brake system prevents the lifting frame 3 from sliding uncontrollably. Each screw rod 301 is connected to the four corners of the lifting frame 3 to ensure a smooth and shake-free lifting process. The four screw rods 301 are synchronously connected by a connecting device and driven by the same motor to achieve synchronous rotation of the four screw rods 301 to prevent the lifting frame 3 from generating errors during the lifting process. The connecting device includes an output shaft 302 arranged at the output end of the motor, and two intermediate shafts 303 are arranged on the output shaft 302. The output shaft 302 and the intermediate shaft 303 are connected by a connecting box. 307 connection, the connecting box 307 changes the transmission direction of the output shaft 302 to achieve synchronous rotation. A transmission shaft 304 is set between the two screw rods 301. The intermediate shaft 303 is connected to the transmission shaft 304 by gears or chains. The two ends of the transmission shaft 304 are connected to the gear plate 306 set on the screw rods 301 through the bevel gear 305. The orthogonal fit between the bevel gear 305 and the gear plate 306 ensures that the four screw rods 301 rotate in the same direction, allowing the lifting frame 3 to move up and down synchronously, preventing errors in the lifting process. When the marble is placed on the lifting frame 3, the marble moves during the cutting process, so that the direction of action of the diamond wire remains basically consistent, greatly improving cutting accuracy and enhancing control effect. Improve production efficiency. The four screw rods 301 realize the synchronous lifting control of the lifting frame 3, ensuring that the stone remains horizontal and stable during the cutting process, which can significantly improve the cutting efficiency and accuracy of hard materials such as marble, and reduce production costs and raw material waste.

[0026] During use, the marble to be cut is placed on the lifting frame 3. The height of the lifting frame 3 is adjusted to maintain an appropriate distance between the stone surface and the diamond wire on roller 2. The drive motor 201 is activated, causing roller 2 to begin rotating. The diamond wire is tensioned through the grooves on roller 2 and rotates at high speed. As the lifting frame 3 slowly rises, the diamond wire gradually cuts into the stone, greatly improving cutting efficiency and accuracy and reducing material waste. The operator can monitor the cutting process in real time through the inspection platform 101 to observe the quality of the cut surface. If necessary, the speed of the lifting frame 3 or the rotation speed of roller 2 can be adjusted to ensure the cutting effect. When the stone is completely cut into the desired shape, the drive motor 201 is turned off, stopping the rotation of roller 2. The cut stone is removed via the lifting frame 3 for subsequent processing.
