A structurally stable rope saw cutting device

Abstract

This utility model relates to a structurally stable wire saw cutting device, comprising two columns, each column having a lifting and moving seat that can move up and down along the column. Each lifting and moving seat has a driving flywheel mechanism and a driven flywheel mechanism, respectively. A wire saw blade for cutting is fitted between the driving and driven flywheel mechanisms. The columns are rectangular, and the lifting and moving seats are rectangular frames fitted onto the rectangular columns. At least two symmetrical inner surfaces of the rectangular frame have several rolling wheels, which rest against the outer wall of the rectangular column. This utility model uses rolling wheels on four sides of the lifting and moving seat on the column, replacing the traditional guide rails and sliders, and using rolling friction instead of traditional sliding friction. This significantly reduces the sliding resistance of the lifting and moving seat during its up and down movement, lowers the moving load of the lifting and moving seat, and makes its movement more stable and smooth.

Description

Technical Field

[0001] This utility model relates to the field of wire saw cutting technology, and more specifically to a wire saw cutting device with a stable structure. Background Technology

[0002] A wire saw cutting machine utilizes the principle of wood cutting with a wire saw, employing the high-speed linear motion of a diamond wire saw to cut materials. It is commonly used for cutting various types of hard materials such as stone and slabs. A wire saw cutting machine typically includes a frame, a worktable, a flywheel drive, a wire saw blade, and an electrical control system. The worktable, mounted on the frame, supports the stone. The wire saw blade is wound around the pre-cut stone and forms a closed loop between the wire saw blade and the flywheel drive. The electrical control system controls the flywheel drive to move the wire saw blade linearly to cut the stone.

[0003] Among these, the worktable used to load the flywheel drive device and wire saw blade is equipped with a lifting mechanism that drives the worktable to move up and down, such as Chinese invention patent CN 115534133 B, a wire saw cutting device and cutting method; or Chinese utility model patent CN 215549853 U, a simple and lightweight wire saw machine. In these existing wire saw cutting machines, the lifting mechanism usually only includes a column, a lead screw mounted on the column, a drive component that drives the lead screw to rotate, and a lifting support connected to the lead screw transmission. The flywheel drive device is fixedly mounted on the lifting support and is driven to move up and down by the lifting support. Furthermore, such lifting mechanisms at most only have slide rails on both sides of the column between the column and the lifting support, and a slider that can move on the slide rails is installed on the lifting support to guide the operation. However, because the flywheel drive itself requires two large metal guide wheels to mount the diamond wire saw blade, and also requires a high-torque motor to drive it, the flywheel drive is under a very heavy load. Therefore, the traditional guide mechanism, which only has guide rails and sliders on both sides of the column, has high sliding friction resistance, and the power of the lifting mechanism is difficult to bear the load. This can easily lead to metal fatigue and wear of the guide rails and sliders, and the up and down movement of the worktable is not stable and smooth. Utility Model Content

[0004] In view of the above problems, this utility model provides a wire saw cutting device with stable structure.

[0005] The present invention adopts the following technical solution: A structurally stable wire saw cutting device includes two columns, each column having a lifting and moving seat that can move up and down along the column. The two lifting and moving seats are respectively provided with an active flywheel mechanism and a driven flywheel mechanism. A wire saw blade for cutting is sleeved between the active flywheel mechanism and the driven flywheel mechanism. The columns are rectangular columns, and the lifting and moving seats are rectangular frames sleeved on the rectangular columns. The rectangular frames have at least two mutually symmetrical inner sides with a plurality of rolling wheels, and the rolling wheels abut against the outer side wall of the rectangular columns.

[0006] Furthermore, each of the four inner sides of the rectangular frame is provided with a plurality of the aforementioned rollers.

[0007] Furthermore, the rolling pulley includes several horizontal rolling wheels and several vertical rolling wheels. The horizontal rolling wheels are horizontally arranged on the front and rear inner sides of the rectangular frame and roll against the front and rear outer side walls of the column respectively. The vertical rolling wheels are vertically arranged on the front and rear inner sides of the rectangular frame and are located on the left and right sides of the front and rear inner sides respectively. The vertical rolling wheels roll against the left and right outer side walls of the column respectively.

[0008] Furthermore, the wire saw cutting device also includes a lifting drive mechanism for driving the lifting moving seat to move up and down. The lifting drive mechanism includes two lifting screws respectively set in two columns, screw connectors that cooperate with the lifting screws to move up and down, and a power mechanism for driving the lifting screws to rotate. The two screw connectors are fixedly connected to the two lifting moving seats respectively.

[0009] Furthermore, the power mechanism includes a drive shaft mounted between the two columns and a servo motor for rotating the drive shaft. The two ends of the drive shaft are respectively connected to two lifting screws through a gearbox.

[0010] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: The lifting and moving seat on the column of this utility model uses rolling wheels arranged on four sides to replace the traditional guide rail and slider. Rolling friction replaces traditional sliding friction, which greatly reduces the sliding resistance of the lifting and moving seat when moving up and down, reduces the moving load of the lifting and moving seat, and makes its movement more stable and smooth.

Detailed Implementation

[0017] The specific implementation of the present invention will now be described with reference to the accompanying drawings.

[0018] Reference Figure 1 and Figure 2 A structurally stable wire saw cutting device includes two columns 10, each column 10 having a lifting and moving seat 20 that can move up and down along the column 10. The two lifting and moving seats 20 are respectively equipped with an active flywheel mechanism 31 and a driven flywheel mechanism 32. A wire saw blade for cutting is sleeved between the active flywheel mechanism 31 and the driven flywheel mechanism 32. The active flywheel mechanism 31, the driven flywheel mechanism 32, and the wire saw blade of this invention are basically the same in structure as existing wire saw cutting devices, and the cutting action and principle are also basically the same, so further details are omitted here.

[0019] Reference Figures 3 to 5 The lifting and moving seat 20 has several rolling wheels 40 on its inner side. The rolling wheels 40 abut against the outer wall of the column 10, and the lifting and moving seat 20 can move up and down on the column 10 via the rolling wheels 40. The wheel body of the rolling wheels 40 is covered with a shock-absorbing rubber sleeve 403. Specifically, the column 10 is a rectangular column 10, and the lifting and moving seat 20 is a rectangular frame fitted onto the rectangular column 10. The rectangular frame has several rolling wheels 40 on at least two mutually symmetrical inner sides, and the rolling wheels 40 abut against the outer wall of the rectangular column 10. The rolling wheel 40 includes a roller 401 and two bearings 402 fitted onto the roller 401. The rolling wheel 40 is mounted on the inner side of the lifting and moving seat 20 via the roller 401. The two bearings 402 are fitted with the aforementioned shock-absorbing rubber sleeve 403, which is made of shock-absorbing rubber material.

[0020] This invention can have several rolling wheels on each of the four inner sides of the rectangular frame, corresponding to the four outer walls of the column 10. Alternatively, a combination of several horizontal rolling wheels 41 and several vertical rolling wheels 42 can be used.

[0021] Reference Figure 4 and Figure 5 In this embodiment, a combination of several horizontal rolling wheels 41 and several vertical rolling wheels 42 is preferably used. Specifically, the horizontal rolling wheels 41 are horizontally arranged on the front and rear inner sides of the rectangular frame, and the horizontal rolling wheels 41 roll against the front and rear outer side walls of the column 10 respectively. The vertical rolling wheels 42 are vertically arranged on the front and rear inner sides of the rectangular frame, and are located on the left and right sides of the front and rear inner sides respectively. The vertical rolling wheels 42 roll against the left and right outer side walls of the column 10 respectively. This utility model adopts the design of horizontal rolling wheels 41 and vertical rolling wheels 42, so that the rolling wheels 40 only need to be installed on the two inner sides of the rectangular frame, while achieving rolling support with the four outer side walls of the column 10. This optimizes the assembly method of the rolling wheels 40, which not only makes it easier to reserve sufficient installation space in the rectangular frame for installing the active flywheel mechanism 31 and the driven flywheel mechanism 32, but also allows for better disassembly and maintenance during later maintenance.

[0022] Reference Figure 2 and Figure 3 The wire saw cutting device also includes a lifting drive mechanism 50 for driving the lifting moving seat 20 to move up and down. The lifting drive mechanism 50 includes two lifting lead screws 51 respectively set in two columns 10, lead screw connecting parts 52 that cooperate with the lifting lead screws 51 to move up and down, and a power mechanism for driving the lifting lead screws 51 to rotate. The two lead screw connecting parts 52 are fixedly connected to the two lifting moving seats 20 respectively. The power mechanism includes a drive shaft 54 ​​mounted between the two columns 10 and a servo motor 55 for rotating the drive shaft 54. The two ends of the drive shaft 54 ​​are respectively connected to the two lifting lead screws 51 through a speed change gearbox 53 for transmission.

[0023] Reference Figures 1 to 5When the wire saw cutting device of this utility model moves up and down to cut stone, the active flywheel mechanism 31 and the driven flywheel mechanism 32 operate, driving the wire saw blade to rotate at high speed; the servo motor 55 operates, synchronously driving the lifting screw 51 to rotate through the drive shaft 54 ​​and two speed gearboxes 53, thereby driving the lifting moving seat 20 to move up and down along the column 10. During movement, the lifting moving seat 20 uses rolling wheels 40 arranged on four sides to replace the traditional guide setting of slide rails and sliders, replacing the traditional sliding friction with rolling friction, which greatly reduces the load on the servo motor 55; at the same time, the rolling wheels 40 use the cooperation of bearings 402 and shock-absorbing rubber sleeves 403 to roll and support the column 10, which can play a shock-absorbing role, reduce the high-frequency vibration of stone cutting, and improve the durability of the equipment and the quality of stone cutting.

[0024] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
