Swing cutting unit and wire cutting machine

Abstract

This invention provides a swing-type cutting unit and a wire cutting machine. The swing mechanism includes a support frame, two first rollers located at the top of the support frame, two second rollers located at the bottom of the support frame, and a lifting mechanism. At least one of the second rollers is connected to the support frame at both ends through a lifting mechanism, which drives the second rollers to adjust their height. The advantages of this invention are: the lifting mechanism can be used to adjust the height of the second rollers according to actual needs, allowing the cutting mesh surface formed between the bottoms of the two second rollers to swing at the required angle to form an inclined surface. This reduces the contact area between the cutting mesh surface and the stone, improving cutting sharpness and enabling more efficient cutting of hard materials.

Description

[Technical Field]

[0001] This utility model relates to the field of cutting machine technology, and in particular to a swing-type cutting unit and a wire cutting machine. [Background Technology]

[0002] Stone is widely used in construction. To turn a whole block of stone into slabs, it needs to be cut using cutting tools. Wire cutting machines are popular because of their advantages, such as a small kerf.

[0003] The wire cutting machine mainly consists of a support frame and a cutting assembly. The cutting assembly is equipped with two sets of rollers. There are two ways to connect the cutting assembly to the support frame: the first is to connect the cutting assembly to the support frame through a lifting device. During operation, the lifting device can be used to drive the cutting assembly to move up and down, such as the spray device for a wire cutting machine and a wire saw with the device disclosed in Chinese invention patent application No. CN202410796131.9; the second is to fix the cutting assembly to the support frame, and use a lifting device to lift the stone upwards during operation.

[0004] However, existing wire cutting machines have the following drawbacks in practical use: the cutting components can only perform flat cuts on stone, resulting in a large contact area between the cutting components and the stone, poor cutting sharpness, and making them unsuitable for efficient cutting of hard materials (such as granite). In view of the above-mentioned problems, the inventors of this case conducted in-depth research on this issue, leading to the development of this invention. [Utility Model Content]

[0005] The technical problem to be solved by this utility model is to provide a swing-type cutting unit and a wire cutting machine, which solves the problem that the cutting components of the existing wire cutting machine can only perform flat cutting on stone, resulting in a large contact area between the cutting components and the stone, poor cutting sharpness, and is not conducive to efficient cutting of hard materials.

[0006] This utility model is implemented as follows:

[0007] In a first aspect, a swing-type cutting unit includes a support frame, two first rollers located at the top of the support frame, two second rollers located at the bottom of the support frame, and a lifting mechanism. At least one of the second rollers is connected to the support frame at both ends through a lifting mechanism, and the lifting mechanism drives the second rollers to adjust their height.

[0008] Furthermore, both ends of the two second rollers are connected to the support frame via a lifting mechanism.

[0009] Furthermore, the lifting mechanism includes a first support base and a driving component. The first support base is mounted on the bearing frame, the driving component is disposed on the first support base, and the movable end of the driving component is connected to the second roller.

[0010] Furthermore, the lifting mechanism also includes guide columns, guide column cylinders, and a first connecting plate; the first support base is provided with guide column cylinders on both sides of the driving component, each guide column cylinder is movably provided with a guide column, the lower end of each guide column is connected to the second roller, and the upper end of each guide column is connected to the first connecting plate; the movable end of the driving component is connected to the first connecting plate.

[0011] Furthermore, the driving component is a telescopic cylinder or a lead screw drive assembly.

[0012] Furthermore, each of the second rollers is provided with a second connecting plate above it, and a second support seat is provided at both ends of the bottom of the second connecting plate. The two ends of the second roller are rotatably connected to the second support seat; the lifting mechanism is connected to the top of the second connecting plate.

[0013] Furthermore, both ends of the second connecting plate are formed with connecting portions, and the width of the connecting portions is greater than the diameter of the second roller, while the width of the portion of the second connecting plate located between the two connecting portions is less than the diameter of the second roller.

[0014] Secondly, a wire cutting machine includes a frame and the aforementioned oscillating cutting unit, which is mounted on the frame.

[0015] By adopting the technical solution of this utility model, at least the following beneficial effects are achieved: By connecting both ends of the second roller located at the bottom of the support frame to the support frame through a lifting mechanism, after the cutting line is wound onto the first roller and the second roller, during actual use, the lifting mechanism can be used to drive the second roller to be raised and lowered according to actual needs. This allows the cutting mesh surface formed between the bottoms of the two second rollers to swing at the required angle to form an inclined surface. In this way, the contact area between the cutting mesh surface and the stone is reduced, which can improve the cutting sharpness and enable more efficient cutting of hard materials (such as granite). At the same time, the wear on the cutting line is also relatively small, which helps to extend the service life of the cutting line. [Attached Image Description]

[0034] Example 1

[0035] Please see Figures 1 to 3As shown, this utility model discloses a swing-type cutting unit 100. The swing-type cutting unit 100 includes a support frame 1, two first rollers 2 located at the top of the support frame 1, two second rollers 3 located at the bottom of the support frame 1, and a lifting mechanism 4. At least one of the second rollers 2 is connected to the support frame 1 at both ends through a lifting mechanism 4, and the lifting mechanism 4 drives the second rollers 3 to adjust their height. In a specific implementation of this utility model, a drive motor 5 is provided at one end of each of the first rollers 2 and the second rollers 3. Cutting lines (not shown) are wound around the two first rollers 2 and the two second rollers 3, forming a cutting mesh between the bottoms of the two second rollers 3. When the drive motor 5 drives the first rollers 2 and the second rollers 3 to rotate, the first rollers 2 and the second rollers 3 can drive the cutting lines to transmit power, thereby enabling the cutting mesh to cut materials such as stone. Meanwhile, during the actual operation, the swing-type cutting unit 100 can drive the second roller 3 to adjust its height through the lifting mechanism 4, thereby changing the cutting mesh surface formed between the bottoms of the two second rollers 3 from a traditional plane to an inclined plane.

[0036] In some embodiments of this utility model, both ends of the two second rollers 3 are connected to the support frame 1 through a lifting mechanism 4. In this way, during actual use, the lifting mechanism 4 can be used to drive any one or two second rollers 3 to be raised or lowered as needed, so that the cutting mesh surface formed between the bottoms of the two second rollers 3 can swing at the required angle to form an inclined surface.

[0037] This invention employs a method where both ends of the second roller 3 located at the bottom of the support frame 1 are connected to the support frame 1 via a lifting mechanism 4. This allows the second roller 3 to be raised and lowered as needed during actual use after the cutting line is wound onto the first roller 2 and the second roller 3. The lifting mechanism 4 can be used to adjust the cutting line between the bottoms of the two second roller 3, allowing the cutting mesh surface to swing at the required angle to form an inclined surface. This reduces the contact area between the cutting mesh surface and the stone, improving the cutting sharpness and enabling more efficient cutting of hard materials (such as granite). At the same time, it reduces wear on the cutting line, thus extending its service life.

[0038] In some embodiments of this utility model, the lifting mechanism 4 includes a first support base 41 and a driving component 42. The first support base 41 is mounted on the bearing frame 1, and the driving component 42 is disposed on the first support base 41. The movable end of the driving component 42 is connected to the second roller 3, so that the driving component 42 can drive the second roller 3 to perform lifting and lowering activities.

[0039] Furthermore, the lifting mechanism 4 also includes guide columns 43, guide column cylinders 44, and a first connecting plate 45; the first support base 41 has guide column cylinders 44 on both sides of the driving component 42, and each guide column cylinder 44 has a guide column 43 movably installed inside it. The lower end of each guide column 43 is connected to the second roller 3, and the upper end of each guide column 43 is connected to the first connecting plate 45; the movable end of the driving component 42 is connected to the first connecting plate 45. In specific operation, the lifting mechanism 4 of this utility model can use the driving component 42 to drive the first connecting plate 45 to move up and down. During the up and down movement of the first connecting plate 45, it will drive the two guide columns 43 to move up and down together, and the two guide columns 43 will drive the second roller 3 to move up and down.

[0040] This invention provides guide cylinders 44 and guide columns 43 on both sides of the drive component 42. The guide columns 43 are movably assembled inside the guide cylinders 44, and the upper ends of the two guide columns 43 are connected to the first connecting plate 45, while the lower ends of the two guide columns 43 are connected to the second roller 3. This allows the drive component 42 to drive the second roller 3 to adjust its height more smoothly during operation.

[0041] In a specific implementation of this utility model, the driving component 42 is a telescopic cylinder or a lead screw drive assembly.

[0042] In some embodiments of this utility model, in order to better connect the second roller 3 and the lifting mechanism 4 together, a second connecting plate 61 is provided above each second roller 3, and a second support seat 62 is provided at both ends of the bottom of the second connecting plate 61. The two ends of the second roller 3 are rotatably connected to the second support seat 62; the lifting mechanism 4 is connected to the top of the second connecting plate 61.

[0043] Furthermore, both ends of the second connecting plate 61 are provided with connecting portions 611, and the width of the connecting portion 611 is greater than the diameter of the second roller 3. The width of the portion of the second connecting plate 61 located between the two connecting portions 611 is less than the diameter of the second roller 3.

[0044] Because a cutting line needs to be wound on the second roller 3 during actual use, this utility model designs the second connecting plate 61 so that the width of the part between the two connecting parts 611 is smaller than the diameter of the second roller 3, which can effectively avoid the second connecting plate 61 interfering with the cutting line; at the same time, connecting parts 611 with a width greater than the diameter of the second roller 3 are set at both ends of the second connecting plate 61, which can facilitate the connection of the lifting mechanism 4 to the connecting parts 611.

[0045] Example 2

[0046] Please see Figures 1 to 4As shown, this utility model discloses a wire cutting machine 200, which includes a frame 7 and a swing-type cutting unit 100. The specific structure and technical effects of the swing-type cutting unit 100 are exactly the same as those in Embodiment 1. Please refer to the detailed description of Embodiment 1 for details, which will not be repeated here. In addition, the other structures of the wire cutting machine 200 of this utility model are the same as those of existing wire cutting machines and belong to the prior art, so they will not be described in detail here. The swing-type cutting unit 100 is installed on the frame 7. In specific implementation, the swing-type cutting unit 100 can be directly fixedly installed on the frame 7, in which case a lifting device (not shown) is needed to lift the stone upwards during operation; or the swing-type cutting unit 100 can be connected to the frame 7 through a lifting device 8, in which case the lifting device 8 can be used to drive the entire swing-type cutting unit 100 to move up and down during operation. In practical use, the wire cutting machine 200 of this utility model can be adjusted by using the lifting mechanism 4 to drive the second roller 3 to lift and lower according to actual needs. This allows the cutting mesh surface formed between the bottoms of the two second rollers 3 to swing at the required angle to form an inclined surface. This reduces the contact area between the cutting mesh surface and the stone, which can improve the cutting sharpness and enable more efficient cutting of hard materials (such as granite). At the same time, it also reduces the wear on the cutting wire and helps to extend the service life of the cutting wire.
