Description

Technical Field

[0001] This utility model relates to the technical field of wood carving art production tools, specifically to a wire cutting carving device. Background Technology

[0002] In the field of wire cutting and carving wood, wire saws use the reciprocating motion of a saw wire (cutting line) to cut and carve wood, and are widely used in crafts, furniture decoration, and other applications. Among existing wire saw equipment, manual wire saws rely on human power to drive the reciprocating motion of the saw wire, resulting in low efficiency, high labor intensity, and poor cutting accuracy. While electric wire saws improve efficiency through motor drive, most use a crank-slider or direct linkage structure to achieve the reciprocating motion of the saw wire, which has the following shortcomings:

[0003] Poor motion stability: Traditional drive structures are prone to causing additional vibrations in the reciprocating motion of the saw wire. Especially during high-speed cutting, the vibration will affect the cutting accuracy, causing burrs or line deviations on the wood surface and reducing the carving quality.

[0004] High structural complexity: Some drive mechanisms contain multiple gears or transmission components, which not only increases the size of the equipment, but also increases the difficulty of assembly and maintenance. Furthermore, transmission backlash is prone to occur after the components wear out, which further affects the motion accuracy.

[0005] Inconvenient saw wire replacement: The saw wire (cutting wire) of existing equipment is usually fixedly connected to the installation structure. When changing saw wires of different specifications (such as thickness and material), multiple parts need to be disassembled, which is cumbersome, affects processing efficiency, and makes it difficult to flexibly adapt to the needs of different wood hardness or carving precision.

[0006] Therefore, there is an urgent need for a wire cutting and engraving equipment with a compact structure, smooth movement, and convenient saw wire replacement to improve the accuracy, efficiency, and operational flexibility of wire cutting and engraving of wood. Utility Model Content

[0019] The wire cutting engraving equipment provided by this utility model has at least the following beneficial effects:

[0020] I. Significantly Improved Motion Stability: Utilizing a cam-connecting rod assembly as the core transmission component of the reciprocating drive mechanism, the rotation of the wire-cutting power component is converted into the vertical reciprocating motion of the mounting component via the cam-connecting rod assembly. The cam-connecting rod structure provides smooth transmission and minimal impact, effectively reducing vibration of the tangent line during reciprocating motion, ensuring a stable tangent line position during cutting, thereby improving the line accuracy of wood carving, reducing burrs and line deviation, and enhancing the surface quality of the carving.

[0021] II. Compact structure and long service life: Compared with the traditional multi-gear or crank-slider structure, the cam connecting rod assembly has fewer parts and a more compact layout, reducing the overall size of the equipment; at the same time, the simplified transmission structure reduces wear points, lowers maintenance difficulty, and extends the service life of the equipment.

[0022] 3. Flexible and efficient replacement of cutting wires: The cutting wires are detachably mounted on the installation components. When it is necessary to change to different specifications of cutting wires according to the hardness of the wood or the carving precision, there is no need to disassemble the complex transmission components. Only the cutting wires need to be directly disassembled and installed, which greatly shortens the replacement time and improves the operational flexibility and processing efficiency of the equipment.

[0023] IV. Strong adaptability: The mounting components can be moved vertically. Combined with the transmission characteristics of the cam connecting rod assembly, the reciprocating frequency and stroke of the tangent can be flexibly adjusted by adjusting the output speed of the wire cutting power component or the cam parameters, so as to adapt to the cutting needs of different types of wood (such as softwood and hardwood) and expand the applicability of the equipment.

[0024] In summary, by optimizing the drive structure and tangent installation method, this equipment improves operational convenience and equipment adaptability while ensuring carving accuracy, making it suitable for wire cutting carving scenarios of various types of wood.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] This utility model provides a wire cutting engraving device, such as... Figures 1 to 8 As shown, the wire cutting engraving equipment includes a support mechanism 1, a wire cutting mechanism 2, and a reciprocating drive mechanism 3.

[0038] The wire cutting mechanism 2 includes an installation component and a cutting wire 21. The installation component is movably mounted on the support mechanism 1 in the vertical direction, and the cutting wire 21 is detachably mounted on the installation component and moves synchronously with the installation component.

[0039] The reciprocating drive mechanism 3 includes a wire cutting power assembly 31 and a cam connecting rod assembly. The rotation drive end of the wire cutting power assembly 31 is connected to the input end of the cam connecting rod assembly, and the output end of the cam connecting rod assembly is connected to the mounting assembly.

[0040] When wire cutting wood, the user places the wood on the support mechanism 1 and starts the wire cutting power assembly 31. The wire cutting power assembly 31 drives the mounting assembly to reciprocate in the vertical direction through the cam connecting rod assembly, and the cutting line 21 moves synchronously. During this process, the user can push the wood to be carved according to the specified trajectory according to the actual needs, so as to realize the cutting and carving of the wood.

[0041] In the aforementioned process, the cam linkage assembly is used as the power transmission structure, which can effectively convert the rotational motion of the drive end of the wire cutting power assembly 31 into the reciprocating motion of the mounting assembly, thereby driving the reciprocating motion of the cutting line 21. The transmission process is smooth, with little impact, which can effectively reduce vibration and thus ensure the cutting quality of the wood.

[0042] Furthermore, the cam connecting rod assembly has a simple and compact structure, which not only ensures the size of the equipment but also has a long service life.

[0043] The installation of the tangent wire using the aforementioned mounting components allows users to replace the corresponding tangent wire 21 according to actual needs, making the structure flexible and applicable to a wide range of applications. Moreover, when replacing the tangent wire 21, the tangent wire 21 can be directly replaced, making disassembly and assembly convenient.

[0044] As an optional implementation, the line-cutting power assembly 31 is configured as an electric power assembly.

[0045] The electric power assembly includes a servo motor and a reducer connected to the servo motor, with the rotation drive end of the reducer connected to the input end of the cam link assembly.

[0046] By using the aforementioned electric power component, the reciprocating frequency can be adjusted by changing the speed of the servo motor during practical applications, thus meeting the cutting requirements of different types of wood.

[0047] As an optional implementation, the cam link assembly includes a drive cam 32 and a drive link 33.

[0048] The rotation drive end of the wire cutting power assembly 31 is provided with an output shaft, which is the output shaft of the reducer. The transmission cam 32 is fixedly sleeved on the output shaft. An eccentric rod is provided on the transmission cam 32.

Specifically, it is rotatably connected to the lower connecting block 231 of the lower quick-connect assembly 23.

[0049] During operation, the wire cutting power assembly 31 drives the transmission cam 32 to rotate, thereby pushing the transmission connecting rod 33 to move, causing the mounting assembly and the tangent 21 to reciprocate in the vertical direction.

[0050] In practical applications, the reciprocating stroke can be adjusted by adjusting the parameters of the transmission cam 32, such as the eccentric distance of the eccentric rod.

[0051] As an optional implementation, the support mechanism 1 includes a frame 11 and a table 12 fixedly mounted on the frame 11. The table 12 is a work surface that provides a support platform for the wood. A relief groove 121 is provided through the table 12, passing through one side of the table 12, and a tangent 21 passes through the relief groove 121.

[0052] As an optional implementation, the mounting assembly includes an upper quick-connect assembly 22 and a lower quick-connect assembly 23. A suspension 13 is provided above the platform 12. The upper quick-connect assembly 22 is movably mounted on the suspension 13 in the vertical direction. The lower quick-connect assembly 23 is movably mounted on the frame 11 in the vertical direction. The top end of the tangent 21 is connected to the upper quick-connect assembly 22, and the bottom end of the tangent 21 is connected to the lower quick-connect assembly 23.

[0053] The upper quick-connect assembly 22 and the lower quick-connect assembly 23 work together to enable quick assembly and disassembly of the tangent 21, thus facilitating rapid replacement. On the other hand, they slide in the vertical direction with the suspension 13 and the frame 11 respectively, effectively limiting their movement trajectory and ensuring the stability of their movement.

[0054] As an optional implementation, the upper quick-connect assembly 22 includes an upper connecting block assembly and an upper quick-connect nut 221. An upper hanging ring 211 is provided at the top of the tangent 21. The upper connecting block assembly is slidably disposed on the suspension 13 in the vertical direction. An upper stud 2231 is provided on the upper connecting block assembly, and the upper hanging ring 211 is attached to the upper stud 2231.

[0055] When installing the top of the tangent 21, the upper hanging ring 211 is attached to the upper stud 2231, and then the upper quick-connect nut 221 is rotated. The upper quick-connect nut 221 moves axially along the upper stud 2231, thereby pressing the upper hanging ring 211 onto the upper connecting block assembly.

[0056] The top of the tangent 21 adopts a combination of hanging structure and threaded structure, which not only makes disassembly and assembly convenient, but also ensures stable installation.

[0057] As an optional implementation, the upper connecting block assembly includes a guide block 222, a connecting tension block 223, and a tension nut 224.

[0058] The suspension 13 has an upper guide groove 131 that runs vertically through it. The guide block 222 is shaped to fit the upper guide groove 131 and passes through the upper guide groove 131 and slides with the upper guide groove 131.

[0059] The guide block 222 has a guide groove 2221 extending vertically; the upper section of the connecting tension block 223 is shaped to fit the guide groove 2221, and the upper section of the connecting tension block 223 is slidably inserted into the guide groove 2221. A tensioning stud 2232 is integrally provided on the top of the connecting tension block 223, and the top end of the tensioning stud 2232 extends out of the guide groove 2221. The tensioning nut 224 is threaded onto the tensioning stud 2232; the upper stud 2231 is provided on the lower section of the connecting tension block 223.

[0060] After the tangent 21 is installed, the tension nut 224 is rotated. The tension nut 224 abuts against the guide block 222 and drives the tension stud 2232 to move axially, thereby pulling the connecting tension block 223 to move axially along the guide groove 2221, thus achieving the tensioning of the tangent 21 and ensuring the cutting effect.

[0061] As an optional implementation, the line cutting mechanism 2 includes a buffer assembly 24, which includes an elastic element 241, which is a spring, and is disposed above the suspension 13. The two ends of the elastic element 241 abut against the guide block 222 and the suspension 13, respectively.

[0062] The buffer component 24 mainly serves a buffering function.

[0063] As an optional implementation, the buffer assembly 24 includes a guide rod 242, which is fixedly mounted on the guide block 222. A guide hole 132 is provided through the suspension 13 in the vertical direction. The guide rod 242 passes through the guide hole 132 and slides with the guide hole 132. An elastic element 241 is sleeved on the guide rod 242.

[0064] The guide rod 242 is used for the installation of the elastic element 241, making the structure more compact, and further limits the movement trajectory of the guide block 222.

[0065] As an optional implementation, the number of buffer components 24 and guide holes 132 is set to multiple.

[0066] Optionally, the guide block 222 is configured as an L-shape, including an integrally formed horizontal bar and a vertical bar connected to the end of the horizontal bar, and the guide rod 242 is disposed on the horizontal bar.

[0067] To further ensure the balance of force, the guide block 222 is set to T-shape. At this time, the top of the vertical rod is connected to the middle position of the horizontal rod, and all the buffer components 24 are symmetrically distributed on the horizontal rod relative to the vertical rod.

[0068] As an optional implementation, the lower quick-connect assembly 23 includes a lower connecting block 231 and a lower quick-connect nut 232. A lower hanging ring 212 is provided at the bottom end of the tangent 21. A lower guide groove 111 is provided vertically through the frame 11. The lower guide groove 111 is shaped to fit the lower connecting block 231. The lower connecting block 231 passes through the lower guide groove 111 and slides with the lower guide groove 111. A lower stud 2311 is provided near the top of the lower connecting block 231. The second end of the transmission connecting rod 33 is hinged to the lower connecting block 231 near the bottom.

[0069] When installing the bottom end of the tangent 21, hook the lower hanging ring 212 onto the lower stud 2311, and then rotate the lower quick-connect nut 232. The lower quick-connect nut 232 moves axially along the lower stud 2311, thereby pressing the lower hanging ring 212 onto the lower connecting block 231.

[0070] The bottom end of the tangent 21 adopts a combination of hanging structure and threaded structure, which not only makes disassembly and assembly convenient, but also ensures stable installation.

[0071] Optionally, the upper quick-connect nut 221, the lower quick-connect nut 232, and the tension nut 224 are all butterfly nuts for easy rotation.
