Description

Technical Field

[0001] This invention relates to a metal wire processing equipment, and more particularly to a metal wire cutting equipment. Background Technology

[0002] Metal wire is a fundamental material in fields such as power transmission, communication cables, precision electronics, fastener manufacturing, and building structures. Its fixed-length cutting or precision cutting is a key process for subsequent assembly and forming. The most common metal wire is stainless steel wire. In order to form a ring structure that matches the spiral skeleton, the filter material needs to be fixed by metal wire sheets. The existing processing method is to cut the whole roll of coiled metal wire into metal wire sheets of the corresponding shape.

[0003] Currently, there are two main methods for cutting metal wire: electrical discharge machining (EDM) and automated mechanical cutting. EDM is generally used in mold making and precision parts processing, and its application is relatively limited. Automated mechanical cutting, on the other hand, is more widely used. For example, in the process of cutting steel sheets for fixing filter elements, existing technology uses coiled feed, and after a series of tensioning rollers to adjust the tension of the wire, it is cut by an automated cutting structure. Using an automated mechanical structure to cut steel sheets can easily result in burrs. Although these burrs do not affect the use, they can easily injure the hands of assembly workers because the steel sheets need to undergo assembly and other manual processing steps afterward. This results in the metal wire needing to be polished separately after cutting, requiring an additional operation step, which not only extends the production time but also increases the processing cost of the wire.

[0004] Therefore, the purpose of this invention is to provide a metal wire cutting device that can pre-treat the wire before cutting and perform the pre-treatment process simultaneously with the cutting process, without the need for a separate processing step. This allows the cut wire to be burr-free, resulting in a low-cost, stable, and reliable product. Summary of the Invention

[0005] This invention provides a metal wire cutting device that can effectively solve the above-mentioned problems.

[0006] This invention is implemented as follows: A metal wire cutting device, comprising: A cutting table, on one side of which wire coils are stacked, and a sliding machine table is provided at the upper end of the cutting table; The guide structure includes a feed guide wheel frame disposed on one side of the cutting table, and a number of opposing guide wheels are disposed on the inner side of the sliding table, with a drive motor disposed at the rear end of the upper guide wheel; A cutting mechanism is disposed on the side of the cutting table away from the wire coil. The cutting mechanism includes a cutting seat disposed on the cutting table, a power structure disposed on the cutting seat, and a cutting blade connected to the lower end of the power structure. A pre-processing mechanism is disposed between the sliding table and the cutting mechanism. The pre-processing mechanism includes a guide seat for guiding the wire. Two opposing filing pieces are movably disposed on both sides of the top surface of the guide seat. A clamping piece is disposed on the top surface of the guide seat. The wire enters the guide seat after being guided by the guide wheel. When the cutting blade processes the subsequent section of the wire, the clamping piece presses against the top of the wire, and the filing piece cuts notches at the upper and lower ends of the wire on the side.

[0007] As a further improvement, the guide seat includes a square platform disposed between the sliding machine table and the cutting mechanism, and a movable platform is movably mounted on the inner side of the square platform, with an inwardly recessed receiving groove in the middle of the movable platform.

[0008] As a further improvement, the receiving trough extends outward with several air guide slits.

[0009] As a further improvement, the filing component includes a mounting base set on a square platform, on which two sets of cylinders are provided. Each cylinder is equipped with a signal element that is linked to the power structure. When the power structure is extended, the cylinder is extended synchronously. A filing blade is connected to the output end of the cylinder.

[0010] As a further improvement, the lower half of the middle section of the receiving groove is provided with an outwardly extending clearance channel, and the lower end of the file blade is flush with the clearance channel.

[0011] As a further improvement, the file includes a locking plate connected to the output end of the cylinder, the locking plate locking the main body of the tool, and the top of the main body of the tool integrally formed with a filing section.

[0012] As a further improvement, an outer reinforcing section is welded to one end of the blade body in the middle of the filing section.

[0013] As a further improvement, the clamping member includes a stamping cylinder connected to the outside of the cutting seat. The starting end of the stamping cylinder is connected in series with the starting end of the air cylinder. The lower end of the stamping cylinder is connected to a clamping seat. The inner side of the clamping seat is provided with a content receiving groove to make way for the wire.

[0014] As a further improvement, a lead screw is provided on the inner side of the cutting table, one end of which is driven by a motor, and a nut is provided at the lower end of the sliding table, which engages with the lead screw through the nut.

[0015] As a further improvement, the rear end of the cutting mechanism is provided with a material dropping structure. The material dropping structure includes a receiving platform located at the end of the cutting seat away from the pretreatment mechanism. The receiving platform is provided with a material dropping seat for accommodating wire. One end of the material dropping seat is connected to the material dropping motor, and the material dropping seat is spaced apart from the cutting mechanism.

[0016] The beneficial effects of this invention are: 1) The present invention uses a pre-processing mechanism that is set between the sliding table and the cutting mechanism. After the wire is tensioned and cut, it can be guided by the guide seat. Then, the top of the wire is limited by the clamping component. Finally, the wire is notched on both sides by the filing component, so that the side has already been broken before cutting. This makes it less likely for burrs to appear on the side during cutting, so that the finished steel sheet will not cut your hands. It is easier to use. Since the above process is set before the cutting mechanism, the processing node is the stage of the previous section of wire being cut. Therefore, there is no waiting time or separate transition process, and it does not affect the normal processing progress.

[0017] 2) Since the wire undergoes separate actions on its sides during the pre-processing stage, the wire is prone to deformation or twisting. Therefore, this invention provides a guide seat with a movable and detachable platform inside. The platform can be changed to different specifications according to the wire's condition, and the inner side of the platform has a receiving groove for limiting the wire, making the wire less prone to deformation when subjected to external forces.

[0018] 3) When filing the wire, if the middle part of the wire is directly rubbed and pressed, burrs will still appear on the upper half of the steel during the cutting process, resulting in poor edge removal. Therefore, the filing device of this invention is equipped with two sets of cylinders and two sets of filing blades. The wire is processed by applying pressure at two points on one side and four points on both sides, so that the four corners of the wire can be pre-treated, thus making it less likely to produce burrs after cutting and less likely to be sharp to the touch.

[0019] 4) If an ordinary file is used, it is easy for the file to break due to insufficient rigidity when it comes into contact with the wire. Therefore, the file pressing tool used in this invention is firstly made of a main body with a thickness equal to the sum of the thickness of multiple files, which has strong rigidity. The other filing pressing sections that come into contact with the wire are also directly integrally formed with the main body of the tool, so that they are not easy to break off from the connection point. In addition, in order to avoid cracks in the filing pressing section during high-frequency contact, this invention also welds an outer reinforcing section to one side of the filing pressing section to the main body of the tool, thereby improving the durability of the filing pressing section.

[0020] 5) The guide seat is set at the bottom of the wire to limit the movement. At the top, the present invention uses a clamping component whose pressing cylinder is driven before the cylinder is driven, thereby fixing the top of the wire before the rubbing action. This ensures the clamping seat fixes the top of the wire, preventing the wire from jumping up and down during the rubbing process and ensuring its stability. Attached Figure Description

Detailed Implementation

[0028] All embodiments of the present invention are intended to fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating that the purpose, technical solution, and advantages of the method are clearer. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Reference Figures 1-5 As shown, a metal wire cutting device includes: a cutting table 10, on one side of which a coil of wire is stacked, and a sliding platform 11 is provided at the upper end of the cutting table 10; a guiding structure, including a feed guide wheel frame 21 provided on one side of the cutting table 10, and a plurality of opposing guide wheels 22 provided on the inner side of the sliding platform 11, with a drive motor provided at the rear end of the upper guide wheel 22; and a cutting mechanism 30, provided on the side of the cutting table 10 away from the coil of wire, the cutting mechanism 30 including a cutting seat 31 provided on the cutting table 10, and a power unit provided on the cutting seat 31. The power structure 32 is connected to a cutting blade 33 at its lower end. A pre-treatment mechanism 40 is disposed between the sliding table 11 and the cutting mechanism 30. The pre-treatment mechanism 40 includes a guide seat 41 for guiding the wire. Two opposing filing pieces 42 are movably disposed on both sides of the top surface of the guide seat 41. A clamping piece 43 is disposed on the top surface of the guide seat 41. The wire enters the guide seat 41 after being guided by the guide wheel 22. When the cutting blade 33 processes the downstream section of the wire, the clamping piece 43 presses against the top of the wire, and the filing piece 42 cuts notches at the upper and lower ends of the wire on the side.

[0031] The entire coil of wire is coiled and fixed by the feeding guide wheel frame 21 and guide wheel 22 in sequence. The wire is then driven forward at a constant speed by the drive motor and cut into steel sheets of the appropriate length by the uniformly moving cutting blade 33. The steel sheets are then fixed by the workers onto the material surrounded by the external oil filter.

[0032] Existing automated mechanical structures for cutting steel sheets often result in burrs. Therefore, this embodiment incorporates a pre-processing mechanism 40, which is positioned between the sliding table 11 and the cutting mechanism 30. After tension adjustment, the wire is guided by the guide seat 41 before cutting. The top of the wire is then limited by the clamping member 43, and finally, the edge filing member 42 files notches on both sides of the wire, creating a break on the side of the steel before cutting. This reduces the likelihood of burrs forming on the side during cutting, preventing the finished steel sheet from cutting into the hand and facilitating smoother use. Since this process is performed before the cutting mechanism 30, and the processing point is during the cutting of the previous section of wire, there is no need for waiting time or a separate transition process, thus not affecting the normal processing progress.

[0033] Since the wire undergoes separate actions on its sides during the pre-processing stage, it is prone to deformation or twisting. Therefore, the guide seat 41 in this embodiment includes a square platform 411 disposed between the sliding table 11 and the cutting mechanism 30. A movable platform 412 is movably installed on the inner side of the square platform 411. The movable platform 412 has an inwardly recessed receiving groove 413 in the middle. Through the guide seat 41, a movable and detachable movable platform 412 is provided inside. The movable platform 412 can be replaced with different specifications according to the wire. The inner side of the movable platform 412 has a receiving groove 413 for limiting the wire, so that the wire is not easily deformed when subjected to external force.

[0034] During the rolling process, the wire is prone to heat up after being squeezed. Therefore, the receiving groove 413 in this embodiment extends outward with several air guide slits 414, and the air guide slits 414 are blown by a fan to reduce the temperature of the wire and prevent deformation.

[0035] If the filing component 42 directly presses the middle of the wire during the filing process, burrs will still appear on the upper half of the steel during the cutting process, resulting in poor edge removal. Therefore, the filing component 42 in this embodiment includes a mounting base 421 set on a square platform 411. The mounting base 421 is equipped with two sets of cylinders 422. The cylinders 422 are equipped with signal components that are linked to the power structure 32. When the power structure 32 is pushed out, the cylinders 422 are pushed out simultaneously. The output end of the cylinders 422 is connected to a filing blade 423. The filing component 42 is equipped with two sets of cylinders 422 and two sets of filing blades 423. The wire is processed by applying pressure at two points on one side and four points on both sides, so that all four corners of the wire can be pre-treated, thus making it less likely to have burrs after cutting and less likely to be sharp to the touch.

[0036] Since the wire is located in the inwardly recessed receiving groove 413, in order to make the file 423 fit, the lower half of the middle section of the receiving groove 413 in this embodiment is provided with an outwardly extending relief channel 415. The lower end of the file 423 is flush with the relief channel 415, so that the lower end of the file can contact the lower side of the wire.

[0037] If an ordinary file is used, it is easy for the file to break due to insufficient rigidity when it comes into contact with the wire. Therefore, the file pressing knife 423 in this embodiment includes a locking plate 4231 connected to the output end of the cylinder 422. The locking plate 4231 locks the knife body 4232. The top of the knife body 4232 is integrally formed with a filing pressing section 4233. The file pressing knife 423 used firstly has a knife body 4232 with a thickness equal to the sum of the thickness of multiple files, which has strong rigidity. Moreover, the filing pressing section 4233 that comes into contact with the remaining wire is also directly integrally formed with the knife body 4232, so it is not easy to break from the connection position.

[0038] Furthermore, to prevent cracks from appearing in the filing section 4233 during high-frequency contact, an outer reinforcing section 4234 is welded to one end of the blade body 4232 from the middle of the filing section 4233 in this embodiment, and an outer reinforcing section 4234 is also welded to one side of the filing section 4233 toward the blade body 4232, thereby improving the durability of the filing section 4233.

[0039] The guide seat 41 is designed to limit the bottom of the wire. At the top, the clamping member 43 in this embodiment includes a stamping cylinder 431 connected to the outside of the cutting seat 31. The starting end of the stamping cylinder 431 is connected in series with the starting end of the cylinder 422. The lower end of the stamping cylinder 431 is connected to a clamping seat 432. The inner side of the clamping seat 432 is provided with a content receiving groove 433 to make way for the wire. Through the clamping member 43, the stamping cylinder 431 is driven before the cylinder 422 is driven, thereby fixing the top of the wire before the twisting action. This ensures the fixing effect of the clamping seat 432 on the top of the wire, preventing the wire from jumping up and down during the twisting process and ensuring its stability.

[0040] In this embodiment, the cutting table 10 is equipped with only one set of sliding platforms 11. However, if other materials require a longer tension adjustment stroke, a lead screw is provided on the inner side of the cutting table 10 in this embodiment. One end of the lead screw is driven by a motor, and a nut is provided at the lower end of the sliding platform 11. The sliding platform 11 cooperates with the lead screw through the nut, and the position of the sliding platform 11 can be changed, and the length of the cutting table 10 can be extended, thereby increasing the number of sliding platforms 11 and thus increasing the number of guide wheels 22.

[0041] To facilitate material collection during the cutting process, the rear end of the cutting mechanism 30 in this embodiment is provided with a material dropping structure 50. The material dropping structure 50 includes a receiving platform 51 located at the end of the cutting seat 31 away from the pretreatment mechanism 40. The receiving platform 51 has a material dropping seat 52 for accommodating wire. One end of the material dropping seat 52 is connected to the material dropping motor 53, and the material dropping seat 52 is spaced apart from the cutting mechanism 30. The cut steel sheet is located on the material dropping seat 52, and then the material dropping motor 53 flips it to make the steel sheet fall off the material dropping seat 52 and into the material collection box below.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
