Description

A type of downward-pressing oscillating wire saw Technical Field

[0001] This utility model is a downward-pressing oscillating wire saw, belonging to the field of stone cutting technology. Background Technology

[0002] A wire saw is a specialized device that uses a metal wire or diamond cutting wire to cut hard and brittle materials such as ceramics and stone in a high-speed reciprocating motion. It completes the cutting operation through the continuous friction between the cutting wire and the workpiece, and is widely used in the processing and production of various materials such as metal, wood, stone, and plastic.

[0003] Traditional wire saws mostly use a fixed pressing or single swing mode, which cannot flexibly switch between pressing and swinging cutting. They lack the dynamic response capability to changes in material hardness and thickness, which can easily lead to chipping of the cut surface or breakage of the wire saw, thus significantly affecting cutting efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a downward-pressing oscillating wire saw machine to solve the problems that traditional wire saw machines mostly adopt a fixed downward pressing or single oscillating mode, which cannot flexibly switch between downward pressing and back-and-forth oscillating cutting, lack the dynamic response capability to changes in material hardness and thickness, and are prone to chipping of the cut surface or breakage of the wire saw, which greatly affects the cutting efficiency.

The spool assembly and the tensioner are jointly installed on the spool base for adjusting and applying tension to the cutting wire. The take-up and undo spool assembly is located below the spool assembly and the tensioner for controlling the take-up and undo of the cutting wire.

[0019] The beneficial effects of this utility model are: In traditional fixed use, this utility model integrates a composite drive structure of pressing and swinging cutting, which can flexibly switch or superimpose the two modes according to parameters such as the hardness of the material and the cutting thickness. Pressing down and swinging reduce the arc length of the contact wire mesh during material cutting, significantly improving cutting efficiency and accuracy, and is more conducive to cutting high-hardness materials.

[0045] Example 2

[0046] For the sake of brevity, the parts that are the same as in Embodiment 1 will not be described again. The main focus here is on the structure that is different from Embodiment 1 of this utility model. The only difference between Embodiment 2 and Embodiment 1 is the driving structure 354.

[0047] Please refer to Figure 8. In this embodiment, to improve the stability of the drive structure 354, the drive structure 354 is specifically a worm gear drive, which includes a rocker gear rack 3541 and a worm 3543 and a worm wheel 3544 that drive the rocker gear rack 3541. The rocker gear rack 3541 is located on the end face of the rocker fixed frame 351 near the rocker movable frame 352. The worm 3543 and the worm wheel 3544 are located on the rocker movable frame 352. A motor for driving the worm 3543 is coaxially arranged on one side of the worm 3543. The worm gear drive achieves a larger transmission ratio and is a multi-tooth meshing transmission, resulting in smoother transmission and lower noise.

[0048] When the operator uses the device, the material is placed on the feeding platform 41. The feeding platform 41 moves along the trajectory of the feeding guide rail 42 to the bottom of the cutting frame 31. The device is then started, and the first reducer 231 drives the transmission shaft 232 to rotate, which in turn drives the second drive motor 33 to rotate. The second drive motor 33 drives the transmission screw 235 to rotate, thereby controlling the reciprocating motion of the lifting frame 22 on the lifting guide rail 21 via the lifting guide rail slider 24. The lifting frame 22 synchronously drives the cutting frame 31 to move, and the cutting frame 31 presses down to cut the material. When switching to the swing mode, the drive structure 354 drives the swing fixed frame 351 and the swing movable frame 352 to swing, thereby driving the cutting frame 31 connected to the swing movable frame 352 to swing and cut. During the cutting process, by integrating the composite drive structure of pressing and swing cutting, the two modes can be flexibly switched or superimposed according to the material hardness, cutting thickness and other parameters. This reduces the contact arc length between the wire mesh and the material during cutting, significantly improving cutting efficiency and accuracy, and is more conducive to cutting high-hardness materials.

It will be apparent to those skilled in the art that this utility model 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 basic characteristics of this utility model.
