Abstract
Description
Technical Field
[0001] This utility model relates to the field of thin sheet cutting machine technology, and in particular to thin sheet cutting machines. Background Technology
[0002] A diamond wire cutting machine, as the name suggests, is a device that uses diamond wire as a cutting tool to precisely cut thin sheet materials. It is widely used for cutting various materials such as ceramics, crystals, glass, metals, rocks, thermoelectric materials, infrared optical materials, composite materials, and biomedical materials, and is especially suitable for the precision cutting of ultra-thin sheets.
[0003] When machining large workpieces, existing diamond wire cutting requires forming a wire mesh larger than the workpiece size. This results in an excessively large support frame for the mesh, making movement inconvenient, power consumption high, and control precision low during workpiece cutting due to its large size. Furthermore, the continuous diamond wire cannot control the torque of each wire, easily leading to wire breakage and impacting processing efficiency.
[0004] Therefore, we propose a thin-film cutting machine to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a thin-blade cutting machine. When using this machine, the problem of diamond wire cutting of large workpieces can be solved by eliminating the need to form a wire mesh larger than the workpiece size. Instead, the wire mesh only needs to be formed to an area equivalent to the cutting area, significantly reducing the height of the support frame. During workpiece cutting, the reduced height leads to a substantial decrease in power consumption and a significant improvement in control precision. The continuous diamond wire allows for the placement of a mechanism to control the torque of each wire, increasing the oscillation function during workpiece cutting and greatly improving the cutting conditions. This significantly reduces wire breakage, improves processing efficiency and precision, and solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A thin-blade cutting machine includes a foundation platform, with supports at both ends of the foundation platform. A lifting screw is installed in the inner wall of the supports, and a screw nut is installed on the outer wall of the lifting screw. A processing frame is installed on the outer wall of the screw nut, and a diamond wire is installed on the inner side of the processing frame. A conveying guide rail is also provided in the middle of the foundation platform, and a conveying platform is installed on the conveying guide rail. Swing shafts are provided on the front and rear sides of the conveying platform, and a swing platform is provided on the inner side of the swing shafts. A swing screw is provided on one side of the swing platform.
[0008] In a further embodiment, a flange is provided on the outer wall of the lead screw nut, and the flange is slidably disposed on the inner wall of the bracket, and the processing frame is fixedly installed on the flange.
[0009] In a further embodiment, the lower end of the oscillating screw is provided with a keyway for connection to a turbine, which is mounted on a conveying platform and driven by a stepper motor. The gearbox is lubricated with lithium-based grease.
[0010] In a further embodiment, multiple diamond wires are provided, and each diamond wire is equipped with a tension sensor and an electromagnetic brake at both ends. The central controller dynamically adjusts the brake pressure according to the sensor data to ensure that the tension of each wire is balanced at both ends. A pulley system is also provided for guidance.
[0011] In a further embodiment, the conveying guide rail uses a high-precision ball bearing slider.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention addresses the issue of using a thin-blade cutting machine when machining large workpieces with diamond wire. Instead of forming a wire mesh larger than the workpiece size, the machine only needs to form a mesh with an area equivalent to the cutting area. This significantly reduces the height of the support frame for the wire mesh. During workpiece cutting, the reduced height leads to a substantial decrease in power consumption and a significant improvement in control precision. The continuous diamond wire allows for the placement of mechanisms to control the torque of each wire, increasing the oscillation function during workpiece cutting and greatly improving the cutting conditions. This, in turn, significantly reduces wire breakage and improves processing efficiency and accuracy. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3The thin-film cutting machine includes a foundation platform 1, which is fixed to the bottom with anchor bolts and concrete, and a conveyor rail 6 is installed on the top. Supports 2 are installed on both sides of the foundation platform 1, and lifting screws 3 are symmetrically distributed on both sides of the processing frame 4. A servo motor drives the screws to rotate, which in turn moves the screw nuts 11 up and down, causing the processing frame 4, mounted on the screw nuts 11, to move up and down along the vertical guide rail. Multiple diamond wires 8 are arranged in equilateral triangles inside the processing frame 4. The cutting grid area is equivalent to a traditional rectangular layout, but the support frame height is reduced by 40%, and the overall height of the equipment is reduced to 1 meter. Within 0.5m, each diamond wire 8 is guided at both ends by a pulley system (φ20mm ceramic wheel). The tension sensor is installed at the midpoint of the line. The signal is converted by the AD module and input to the PLC. A conveying platform 5 is set on the conveying guide rail 6. The conveying platform 5 slides on the conveying guide rail 6 to move. A swing shaft 7 is installed on the upper end of the conveying platform 5. A swing platform 9 is installed on the inner wall of the swing shaft 7. A swing screw 10 is installed on one side of the swing platform 9. In use, the swing shaft 7 is rigidly connected to the swing platform 9 through a keyway. A worm gear reducer is installed at the end of the swing screw 10 to drive the platform to swing around the shaft. The swing frequency can be adjusted by PLC programming.
[0022] The working principle of this utility model is as follows: As shown in the figure, the workpiece is placed on the conveying platform 5 and positioned to the cutting area by the guide rail. The lifting screw 3 drives the processing body to descend to the initial cutting position. The diamond wire 8 starts high-speed reciprocating motion, and at the same time, the swing platform 9 swings at a preset frequency. Meanwhile, the tension control system monitors and adjusts the wire tension in real time. After each layer of cutting is completed, the lifting screw 3 rises by 0.1mm (adjustable), and the cycle continues until the workpiece is cut.
[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
