Description

Technical Field

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

[0002] After being polished, marble is very beautiful and is mainly used for processing into various profiles and plates for use as the walls, floors, platforms, and columns of buildings. It is also commonly used as materials for commemorative buildings such as monuments, towers, and statues. Marble can also be carved into arts and crafts, stationery, lamps, utensils, and other practical artworks.

[0003] When cutting large pieces of marble, a saw is generally used for cutting. When using a saw for cutting, the saw makes a reciprocating motion, and the large marble slowly rises. The saw blade is usually relatively thick, generally 3 - 5 mm. This cutting method not only has a slow cutting speed, a thick marble slice after cutting, and low cutting efficiency, but also causes a large amount of waste of raw materials. The knife marks on the marble surface are obvious, and the subsequent surface treatment is relatively complex. When using a wire saw for cutting, in the existing wire saws, the roller drives the diamond wire to move up and down during the cutting process, which will cause errors during the cutting process. Therefore, the present technical solution is proposed for improvement. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiency in the prior art that the cutting error is relatively large due to the diamond wire being a moving part during the cutting process of marble, and to provide a wire saw with a lifting device.

[0005] In order to achieve the above purpose, the embodiments of the utility model specifically adopt the following technical solutions: A wire saw with a lifting device includes a mounting frame. A lifting frame for placing the to-be-cut body is arranged at the bottom of the mounting frame. A cutting part is arranged at the upper part of the mounting frame. The cutting part includes rollers horizontally arranged on the mounting frame around which a diamond wire is wound. Four rollers are arranged in parallel. The bottom of the mounting frame is fixed on a base. The lifting frame includes a lead screw arranged at the bottom of the mounting frame. Four lead screws are arranged and are respectively connected to the four corners of the lifting frame. The lead screws are synchronously rotated through a connecting device.

[0006] Further, the lead screws are connected to the same driving device.

[0007] Further, the connecting device includes an output shaft arranged at the output end of the driving device. Two intermediate shafts are arranged on the output shaft. A transmission shaft drive is arranged between the two lead screws. The output shaft is connected to the intermediate shaft through a connecting box. The intermediate shaft is connected to the transmission shaft through a connecting member.

[0008] Further, the output end of the connecting box is connected to the intermediate shaft. Both ends of the transmission shaft drive gear disks through two bevel gears to rotate the lead screws.

[0009] Further, an inspection platform is provided at the middle position of the mounting frame, and a staircase is provided on one side of the inspection platform.

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

[0011] The beneficial effects of the embodiments of the present utility model are as follows: The four lead screws are synchronously connected through the connecting device and driven by one motor, so that the four corners of the lifting frame can be lifted and lowered synchronously, reducing the error generated during the lifting of the lifting frame. During the cutting process, the roller and the diamond wire remain fixed, enabling the diamond wire to maintain a high rotational speed and greatly reducing the deviation generated when the diamond wire moves under a stressed state. During the cutting process, the marble moves, making the acting direction of the diamond wire basically consistent, greatly improving the cutting accuracy and enhancing the control effect.

Detailed Embodiments

[0017] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0018] See Figures 1 to 4, an embodiment of the present utility model discloses a diamond wire cutting machine, which mainly consists of a mounting frame 1, a lifting frame 3, a cutting part, a base, an inspection platform 101 and auxiliary devices. The mounting frame 1 serves as the support frame of the entire device 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, and can be selected for installation according to the use environment. Multiple diversion grooves are opened on the upper surface of the base to discharge the coolant and residues during the cutting process, improving stability and use effect.

[0019] The bottom of the mounting frame 1 is designed as an open-frame, facilitating maintenance and observing the cutting process. Reinforcing ribs are provided at both the top and bottom to enhance the overall stiffness. When installing, ensure that the mounting frame 1 is horizontally installed. 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 mutually parallel rollers 2. The installation positions of the rollers 2 are arranged in a rectangular layout. The two lower rollers 2 are arranged inside the inspection platform 101 to improve the compactness of the device. And there are multiple precision-machined grooves on the surface of the rollers 2 for accommodating and guiding the diamond wire for cutting. The distance between the upper roller 2 and the lower roller 2 is relatively large to prevent the upper diamond wire from affecting the cutting effect after the marble is cut by the lower diamond wire, ensuring safety in use and improving production quality. A protective plate 103 is provided on the side of the roller 2, and the protective plate 103 can be disassembled to prevent the debris generated during the cutting process from splashing and injuring people, while protecting the roller 2 from external interference and ensuring production safety. At the same time, standing on the inspection platform 101 also increases the operation space. The staircase 102 on one side facilitates personnel to go up and down. And the entire mounting frame 1 and inspection platform 101 can select different sizes according to different marble production specifications. Driving motors 201 are installed on all four rollers 2 to provide sufficient power for the diamond wire and ensure the production effect.

[0020] Both ends of the roller 2 are installed on the mounting frame 1 through bearing seats 202, and one end is connected to the driving motor 201. The high-speed rotation of the roller 2 is realized through the bearing seats 202, ensuring the stability in use, the use effect, prolonging the service life and reducing the failure rate.

[0021] 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 vertical lead screws 301 arranged at the lower part of the mounting frame 1. The brake system of the motor is used to prevent the lifting frame 3 from slipping uncontrollably. Each lead screw 301 is respectively connected to the four corners of the lifting frame 3 to ensure a stable lifting process without shaking. The four lead screws 301 are synchronously connected through a connecting device and are driven by the same motor to achieve the synchronous rotation of the four lead screws 301, reducing the error generated during the lifting process of the lifting frame 3. The connecting device includes an output shaft 302 arranged at the output end of the motor. Two intermediate shafts 303 are arranged on the output shaft 302. The output shaft 302 and the intermediate shafts 303 are connected through a connecting box 307 to change the transmission direction of the output shaft 302 and achieve synchronous rotation. A transmission shaft 304 is arranged between two lead screws 301. The intermediate shafts 303 and the transmission shaft 304 are connected through a connecting piece. The connecting piece can be one of a gear, a chain, etc. The two ends of the transmission shaft 304 are connected to the gear discs 306 arranged on the lead screws 301 through bevel gears 305. Through the positive thread fit between the bevel gears 305 and the gear discs 306, the rotation directions of the four lead screws 301 are the same, enabling the lifting frame 3 to move up and down synchronously, preventing errors generated during the lifting process, and placing the marble on the lifting frame 3. During the cutting process, the marble moves, making the acting direction of the diamond wire basically consistent, greatly improving the cutting accuracy and the control effect. The four lead screws 301 achieve the synchronous lifting control of the lifting frame 3, ensuring that the stone remains horizontal and stable during the cutting process, and can significantly improve the cutting efficiency and accuracy of hard materials such as marble, reducing production costs and raw material waste.

[0022] During the use process, place the marble body to be cut on the lifting frame 3, adjust the height of the lifting frame 3 so that the surface of the stone is at an appropriate distance from the diamond wire on the roller 2, start the driving motor 201 to make the roller 2 start to rotate. The diamond wire is tensioned and rotated at high speed through the grooves on the roller 2. As the lifting frame 3 slowly rises, the diamond wire gradually cuts into the interior of the stone, greatly improving the cutting efficiency and accuracy and reducing raw material waste. The operator can monitor the cutting process in real time through the inspection platform 101 and observe the quality of the stone cutting surface. If necessary, the speed of the lifting frame 3 or the rotation speed of the roller 2 can be adjusted in time to ensure the cutting effect. When the stone is completely cut into the required shape, turn off the driving motor 201 to stop the rotation of the roller 2. Take out the cut stone through the lifting frame 3 for subsequent processing.
