Description

Technical Field

[0001] The present invention relates to the technical field of multi-wire saw equipment, and in particular to a cutting device and a multi-wire saw equipment. Background Art

[0002] With the advancement of science and technology, cutting devices have gained widespread application in industrial production, particularly in the precision cutting of hard and brittle materials such as graphite and silicon crystals. Currently, common cutting devices primarily consist of a driving wheel, a driven wheel, and a cutting wire, which cuts the material through the high-speed motion of the cutting wire.

[0003] However, existing cutting devices still face several technical challenges in practical application. First, during multi-wire sawing, multiple pieces of material are cut simultaneously, requiring time for manual unloading. Existing multi-wire saws are unable to effectively stagger the completion times of the materials being cut, making it difficult for humans to remove all the material in a short period of time. Materials that are not removed promptly are prone to falling, which not only damages the material and affects product quality, but can also damage the equipment and increase maintenance costs.

[0004] Secondly, during the cutting process, the material to be cut is affected by various factors such as uneven weight distribution and uneven force during cutting, which can easily cause displacement and shaking, resulting in large deviations in the thickness of the cutting material and affecting the cutting accuracy. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a cutting device and a multi-wire saw device to solve the technical problems of the prior art cutting devices, such as inconvenient material cutting, large deviation in the verticality of the cutting line resulting in low cutting efficiency and poor cutting accuracy.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The present invention provides a cutting device, comprising a driving wheel, a driven wheel group, an auxiliary guide wheel assembly, and a cutting line, wherein the cutting line is wound between the driving wheel, the driven wheel group, and the auxiliary guide wheel assembly. The driven wheel group includes at least three driven guide wheels, the driving wheel and the three driven guide wheels are arranged in a rectangular array, and the auxiliary guide wheel assembly is disposed between two adjacent driven guide wheels. The auxiliary guide wheel assembly includes at least two auxiliary guide wheels, each of which is composed of a plurality of auxiliary wheels arranged along a first direction, each of which is provided with a guide groove, the cutting line being located within the guide groove, and the depth of the plurality of guide grooves arranged along the first direction increasing sequentially.

[0008] In a possible implementation, the plurality of auxiliary wheels are arranged at equal intervals.

[0009] In a possible implementation, the depths of the plurality of guide grooves arranged along the first direction increase according to an arithmetic progression.

[0010] In a possible implementation, the auxiliary guide wheel further includes a plurality of rolling bodies, two of the rolling bodies are disposed between two adjacent auxiliary wheels, and the two rolling bodies are disposed along the radial direction of the auxiliary wheels.

[0011] In a possible implementation, the two rolling elements are symmetrically arranged with the axis of the auxiliary wheel as the center of symmetry.

[0012] In a possible implementation, the diameter of the auxiliary wheel is smaller than the diameter of the driven guide wheel.

[0013] The present invention further provides a multi-wire saw device, comprising a base and the above-mentioned cutting device, wherein the cutting device is mounted on the base.

[0014] The beneficial effects of the present invention are that, compared with the prior art, firstly, the present invention sets an auxiliary guide wheel assembly, wherein the auxiliary guide wheel is composed of a plurality of auxiliary wheels, and the depth of the guide grooves on the plurality of auxiliary wheels increases successively. This setting form enables the auxiliary wheel with the shallowest guide groove to first contact the material to be cut and complete the cutting of the material to be cut first, and the auxiliary wheel with the deepest guide groove to last contact the material to be cut and complete the cutting of the material to be cut last, staggering the cutting completion time of each cutting line, providing sufficient operation time for manual unloading, thereby solving the problem of inconvenient unloading; secondly, the auxiliary wheel applies radial force to the cutting line, and the guide groove can limit the cutting line, so that the cutting line maintains a stable axis shape, ensuring the verticality accuracy during the cutting process, thereby reducing the verticality deviation of the cutting line. In summary, the technical solution of the cutting device provided by the present invention can solve the technical problems of the existing cutting device such as inconvenient unloading, large deviation of the verticality of the cutting line, low cutting efficiency, and poor cutting accuracy.

[0019] In order to solve the above technical problems, the present invention provides a cutting device and a multi-wire saw device. The technical solutions and embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0021] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0022] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0023] like Figure 1 and Figure 2As shown, the present invention provides a cutting device 1, comprising a driving wheel 11, a driven wheel assembly 12, an auxiliary guide wheel assembly 131, and a cutting line 14. The cutting line 14 is wound between the driving wheel 11, the driven wheel assembly 12, and the auxiliary guide wheel assembly 131. The driven wheel assembly 12 includes at least three driven guide wheels 121. The driving wheel 11 and the three driven guide wheels 121 are arranged in a rectangular array, and an auxiliary guide wheel assembly 131 is provided between two adjacent driven guide wheels 121. The auxiliary guide wheel assembly 131 includes at least two auxiliary guide wheels 131. The auxiliary guide wheel 131 is composed of a plurality of auxiliary wheels 1311 arranged along a first direction. Each of the plurality of auxiliary wheels 1311 is provided with a guide groove 1313. The cutting line 14 is located within the guide groove 1313, and the depth of the plurality of guide grooves 1313 arranged along the first direction increases sequentially.

[0024] First, the present invention sets an auxiliary guide wheel 131 assembly 13, wherein the auxiliary guide wheel 131 is composed of multiple auxiliary wheels 1311, and the depth of the guide groove 1313 on the multiple auxiliary wheels 1311 increases successively. This setting form enables the auxiliary wheel 1311 with the shallowest guide groove 1313 to first contact the material to be cut and complete the cutting work of the material to be cut first, and the auxiliary wheel 1311 with the deepest guide groove 1313 to last contact the material to be cut and complete the cutting work of the material to be cut last, staggering the cutting completion time of each cutting line 14, providing sufficient operation time for manual unloading, thereby solving the problem of inconvenience in unloading.

[0025] Secondly, the auxiliary wheel 1311 applies radial force to the cutting line 14, and the guide groove 1313 can limit the cutting line 14, so that the cutting line 14 maintains a stable axis shape, ensuring the verticality accuracy during the cutting process, thereby reducing the verticality deviation of the cutting line 14.

[0026] In addition, since the cutting completion time of each cutting line 14 is staggered, the operator can remove the cut materials in an orderly manner, avoiding the falling phenomenon caused by the failure to remove the cut materials in time, greatly improving the convenience and safety of production operations, reducing the risk of damage to the cut materials, and improving the product qualification rate.

[0027] Specifically, if Figure 1 As shown, the number of auxiliary wheels 1311 can be five.

[0028] In actual production applications, the specific number of auxiliary wheels 1311 can be customized according to production needs.

[0029] It should be noted that the first direction is the axial direction of the auxiliary wheels 1311 , that is, the multiple auxiliary wheels 1311 are arranged in sequence along the same axis.

[0030] In an optional embodiment, multiple auxiliary wheels 1311 are arranged at equal intervals. This design allows the cutting line 14 to be evenly stressed when passing through the auxiliary guide wheel 131 assembly 13, reducing the risk of local stress concentration and thus reducing the breakage rate of the cutting line 14.

[0031] In an optional embodiment, the depths of the plurality of guide grooves 1313 arranged along the first direction increase in an arithmetic progression. That is, the depth tolerance of every two adjacent guide grooves 1313 is the same. This arrangement allows the cutting line 14 to experience a more gradual height change as it passes through the auxiliary guide wheel 131 assembly 13, thereby reducing vibration and deformation of the cutting line 14 during operation and improving the machining accuracy of the cutting line 14.

[0032] In an alternative embodiment, see Figure 1 The auxiliary guide wheel 131 further includes a plurality of rolling bodies 1312 . Two rolling bodies 1312 are disposed between two adjacent auxiliary wheels 1311 , and the two rolling bodies 1312 are disposed along the radial direction of the auxiliary wheels 1311 .

[0033] The configuration of the rolling elements 1312 significantly improves the synchronization of the rotational speeds of the auxiliary wheels 1311. Through the transmission function of the rolling elements 1312, the rotational speed deviations of adjacent auxiliary wheels 1311 are strictly controlled within the process tolerance range. This effectively suppresses friction loss and vibration caused by excessive speed differences between the auxiliary wheels 1311 during operation, reduces operational fluctuations, and provides a more reliable transmission foundation for the cutting line 14.

[0034] Specifically, the number of rolling elements 1312 may be eight.

[0035] In actual production applications, the specific number of rolling elements 1312 needs to be customized according to the specific number of auxiliary wheels 1311 .

[0036] In an optional embodiment, the two rolling bodies 1312 are symmetrically arranged with the axis of the auxiliary wheel 1311 as the center of symmetry.

[0037] This symmetrical structural design ensures that the auxiliary wheel 1311 maintains a state of dynamic vertical balance during operation. The symmetrically arranged mechanical transmission mechanism effectively offsets torque deviations caused by radial loads, suppressing axial movement or yaw of the auxiliary wheel 1311 during high-speed operation. This improves the stability of the transmission system, reduces mechanical wear caused by uneven force, and provides more reliable support for the smooth operation of the cutting line 14.

[0038] In an optional embodiment, the diameter of the auxiliary wheel 1311 is smaller than the diameter of the driven guide wheel 121 .

[0039] The diameter of the auxiliary wheel 1311 is smaller than the diameter of the driven guide wheel 121. This design can ensure that the auxiliary guide wheel can flexibly guide the cutting line 14, shorten the flexible length of the cutting line 14, and accurately control the running trajectory of the cutting line 14, thereby improving cutting accuracy, reducing processing allowances, and reducing equipment maintenance costs.

[0040] In an optional embodiment, the auxiliary wheels 1311 can be made of a high-hardness alloy material with a precision-machined surface. Each auxiliary wheel 1311 is provided with a guide groove 1313 whose width matches the diameter of the cutting line 14. The rolling elements 1312 can be made of high-precision bearing steel with a precision-ground surface to reduce friction when the rolling elements 1312 contact the cutting line 14, thereby improving the operating efficiency of the cutting device 1.

[0041] like Figure 3 As shown, the present invention further provides a multi-wire saw device 2 , comprising a base 21 and the above-mentioned cutting device 1 , wherein the cutting device 1 is mounted on the base 21 .

[0042] In an optional embodiment, the base 21 is made of metal, offering excellent stability and vibration resistance. A shock-absorbing pad is provided at the bottom of the base 21 to effectively reduce vibration during operation and improve cutting accuracy. A workbench is mounted on the base 21, which can be moved horizontally to adjust the position of the material to be cut. A fixture is provided on the workbench to secure the material to be cut. The driving wheel 11 of the cutting device 1 is driven by a motor, and the motor speed can be adjusted according to different cutting requirements.

[0043] In an optional embodiment, the multi-wire saw apparatus 2 may also be equipped with a cooling system to cool the cutting wire 14 and the material being cut during the cutting process, preventing overheating and resulting deterioration in cut quality. The cooling system includes a water pump, a water tank, a nozzle, and a recovery device. Coolant is sprayed onto the cutting area through the nozzle, then collected by the recovery device and returned to the water tank, forming a closed-loop circulation system.

[0044] In an optional embodiment, the base 21 can be designed with a modular structure, allowing for combination and expansion according to different cutting requirements. A multi-axis workbench can be installed on the base 21, enabling precise movement in the X, Y, and Z axes, as well as angle adjustment of the A and B rotation axes, to meet the needs of cutting complex three-dimensional shapes. The cutting device 1 can be mounted on the base 21 via precision slides, allowing for precise horizontal and vertical positioning.

[0045] In an optional embodiment, the multi-wire saw apparatus 2 may also be equipped with a laser positioning device for precisely positioning the material to be cut and previewing the cutting path before cutting. The laser positioning device projects the trajectory of the cutting line 14 onto the surface of the material to be cut, allowing the operator to visually visualize the cutting results, thereby avoiding cutting errors and improving cutting accuracy.

[0046] In an optional embodiment, the multi-wire saw device 2 can also be equipped with a waste recycling system for collecting waste and coolant generated during the cutting process. After filtering and treatment, the coolant can be recycled and the waste can be centrally processed, reducing environmental pollution.

[0047] The above description is merely a preferred embodiment of the present invention, and the above specific embodiment is not intended to limit the present invention. Various variations and modifications are possible within the technical scope of the present invention. Any modifications, alterations, or equivalent substitutions made by a person skilled in the art based on the above description are within the scope of protection of the present invention.
