5G communication connector copper-nickel-silicon alloy strip preparation system and method

Abstract

The invention relates to the technical field of longitudinal shearing of copper-nickel-silicon alloy strips, and discloses a preparation system and method for a copper-nickel-silicon alloy strip of a 5G communication connector. When no alloy metal plate is subjected to longitudinal shearing treatment, the disc blade moves upwards to be separated from the longitudinal shearing treatment position, and the dust suction pipe opening is synchronously controlled to deflect to be away from the longitudinal shearing treatment position along with the upward movement of the disc blade, so that the dust suction pipe opening deflects to be away from the position of the disc blade, and the disc blade is convenient to disassemble, assemble and maintain; when the alloy plate is conveyed again, the disc blade moves downwards again to the position of longitudinal shearing treatment, the disc blade synchronously controls the dust suction pipe opening to deviate to the position facing the position of longitudinal shearing treatment, and when the dust suction pipe opening conducts longitudinal shearing treatment on the position of longitudinal shearing treatment, dust removal treatment is directly conducted on the position where metal dust is generated; and therefore, metal dust generated when the alloy plate is subjected to longitudinal shearing treatment can be subjected to dust removal treatment at the same time, and potential safety hazards caused when workers carry out longitudinal shearing treatment on the alloy plate are reduced.

Description

Technical Field

[0001] This invention relates to the field of slitting technology for copper-nickel-silicon alloy strips, specifically to a system and method for preparing copper-nickel-silicon alloy strips for 5G communication connectors. Background Technology

[0002] A slitting machine, also known as a slitting line, longitudinal cutter, or strip cutter, is a type of metal slitting equipment. It is primarily used to uncoil, slit, and rewind metal coils into strips of the required width. However, in the processing of copper-nickel-silicon alloy strips, small, precision slitting machines are required for accurate slitting of the alloy.

[0003] In existing slitting machines, such as the Chinese patent CN118254003B, a limiting component is used. The higher end of the strip is on the support component, while the middle of the strip is suspended and the bottom end is supported by the base plate. The support component positions the bottom support point of the strip at the end of the base plate closest to the support component. In this way, the weight of the strip itself will press the strip against the base plate, ensuring that the part of the strip above the base plate is tightly against it. The weight of the strip itself is used to compress the strip, thus limiting its position. For ultra-thin strips, since the weight of ultra-thin strips is relatively small, the compression force on the strip on the base plate is also small, so it will not bend due to excessive compression force. A grinding component, in conjunction with the support component, cleans the burrs at the bottom of the strip. The burrs generated during the cutting process are cleaned from multiple directions in two steps, which can prevent the burrs from being pushed to other directions and not being cleaned properly.

[0004] However, the following problems still exist: In order to facilitate the replacement of disc blades, there are often no other structures near the shaft roller where the disc blades are installed, which means that the metal dust generated when shearing copper-nickel-silicon alloy strips will not be treated, posing a significant safety hazard to the health of workers. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a system and method for preparing copper-nickel-silicon alloy strip for 5G communication connectors. This system features simultaneous dust removal of metal dust generated during the slitting process of the alloy sheet, reducing safety hazards for workers during slitting and indirectly improving equipment safety. It also solves the problem that the lack of other structures near the rollers where the disc blades are installed often results in the metal dust generated during the shearing of copper-nickel-silicon alloy strips not being treated, posing a significant health hazard to workers.

A side shaft is provided between the gear distribution box and the upper guide roller, one end of the side shaft being poweredly connected to the gear distribution box and the other end being poweredly connected to the upper guide roller.

[0011] Preferably, a conveyor frame is fixedly arranged next to the base. The conveyor frame has an arc-shaped structure, with the top of the conveyor frame facing the position of the longitudinal cutting process. Multiple conveyor rollers are rotatably fitted on the conveyor frame, and the conveyor rollers are evenly distributed on the conveyor frame. The upper guide roller is located between the conveyor rollers and the cutter shaft.

[0012] Preferably, the auxiliary mechanism further includes a connecting pipe, which is provided on the base and is adjacent to the cutter shaft. Multiple dust extraction ports are fixedly installed on the connecting pipe, which are evenly arranged adjacent to each other and all connected to the connecting pipe. Two bearing seats are fixedly installed on the base, each bearing seat being adjacent to a vertical rail on one side.

[0015] One method, using the aforementioned 5G communication connector copper-nickel-silicon alloy strip fabrication system, includes the following steps: S1: The alloy sheet is fed into the longitudinal shearing mechanism; S2: The alloy sheet is longitudinally sheared using the disc blade; S3: During the longitudinal shearing process, the dust extraction port removes the metal dust generated at the longitudinal shearing location.

[0016] Compared with the prior art, the present invention provides a 5G communication connector copper-nickel-silicon alloy strip preparation system, which has the following beneficial effects: 1. This 5G communication connector copper-nickel-silicon alloy strip preparation system feeds alloy sheets into a slitting mechanism, where a disc blade performs slitting. Simultaneously, a dust extraction port removes metal dust generated at the slitting location. When no alloy sheet is being slitting, the disc blade moves upwards to move away from the slitting position. This upward movement of the disc blade synchronously deflects the dust extraction port away from the slitting location, facilitating the disassembly and maintenance of the disc blade. When alloy sheets are being re-fed, the disc blade moves downwards back to the slitting position, and the dust extraction port is simultaneously deflected towards the slitting location. This allows the dust extraction port to directly remove dust at the point of metal dust generation during slitting, reducing safety hazards for workers and improving equipment safety.

[0017] 2. The 5G communication connector copper-nickel-silicon alloy strip preparation system, through the setting of spray tank and spray pipe, after the gas containing metal dust enters the spray tank, the spray pipe uses an external water supply system to send water to spray and remove the metal dust gas entering the spray tank, so as to send the metal dust into the water for discharge, thereby purifying the air quality near the longitudinal shearing process.

[0018] 3. The 5G communication connector copper-nickel-silicon alloy strip preparation system uses a U-shaped structure design for the drain pipe. This design allows some water to be retained in the U-shaped structure of the drain pipe during drainage, creating a water seal effect. This ensures that the generated airflow will only flow from the lower end to the upper end of the spray tank, preventing the drain pipe from affecting the airflow direction and thus ensuring the quality of the spray treatment.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a system and method for preparing copper-nickel-silicon alloy strip for 5G communication connectors.

[0023] Example 1, a typical implementation of this application, such as Figure 1As shown, a 5G communication connector copper-nickel-silicon alloy strip preparation system includes a base 1, a slitting mechanism 2 disposed on the base 1, and an auxiliary mechanism 3 disposed on the base 1. The slitting mechanism 2 uses a disc blade 25 to press against the conveying trajectory of the alloy sheet, so that the alloy sheet conveyed to the base 1 is slitted by the disc blade 25. The auxiliary mechanism 3 includes a dust extraction port 32, which is located next to the disc blade 25. The dust extraction port 32 is deflected toward the longitudinal shearing position by the downward movement of the disc blade 25.

[0024] When using this invention: The alloy sheet is fed into the slitting mechanism 2, where it is slitted by the disc blade 25. Simultaneously, the dust extraction port 32 removes metal dust generated at the slitting location. When no alloy sheet is being slitted, the disc blade 25 moves upward to move away from the slitting position. As the disc blade 25 moves upward, the dust extraction port 32 is simultaneously deflected away from the slitting position, facilitating the removal of the disc blade 25. During maintenance and when the alloy sheet is re-fed, the disc blade 25 moves down to the slitting position. Simultaneously, the disc blade 25 controls the dust extraction port 32 to deflect towards the slitting position. This allows the dust extraction port 32 to directly remove dust at the location where metal dust is generated during the slitting process. Consequently, the metal dust generated during the slitting of the alloy sheet is simultaneously removed, reducing safety hazards for workers and improving the safety of the equipment.

[0025] Example 2, as Figures 2-5 As shown, the difference from the above embodiment is that the slitting mechanism 2 includes a vertical rail 21. Two vertical rails 21 are provided on the base 1. The vertical rails 21 are symmetrically distributed at both ends of the slitting position. Each vertical rail 21 is slidably fitted with a bearing moving seat 22. The width of the bearing moving seat 22 is adapted to the width of the vertical rail 21. Multiple hydraulic rods 23 are fixedly installed on the base 1. Each hydraulic rod 23 is located above each bearing moving seat 22. The extension rods of the hydraulic rods 23 all pass through the base 1 and extend into the vertical rail 21. The extension rods of each hydraulic rod 23 are fixedly connected to each bearing moving seat 22.

[0026] Furthermore, a cutter shaft 24 is provided between the bearing moving seats 22. The two ends of the cutter shaft 24 are rotatably engaged with each bearing moving seat 22. Multiple mounting slots are provided on the cutter shaft 24. Multiple disc blades 25 are fixedly mounted on the cutter shaft 24. Each disc blade 25 is adapted to each mounting slot. A material support roller 26 is rotatably engaged on the base 1. The material support roller 26 is located directly below the cutter shaft 24. The size of the material support roller 26 is the same as the size of the cutter shaft 24.

[0027] Furthermore, an upper guide roller 27 is rotatably fitted on the base 1. The upper guide roller 27 is located on one side of the cutter shaft 24. Two lower guide rollers 28 are rotatably fitted on the base 1. The lower guide rollers 28 are symmetrically distributed on both sides of the cutter shaft 24. The lower guide roller 28 on one side of the cutter shaft 24 is located directly below the upper guide roller 27. The lower guide roller 28 and the material support roller 26 are at the same height. The lower guide roller 28 is adjacent to the upper guide roller 27.

[0028] Furthermore, a gearbox 29 is fixedly installed on the base 1. The gearbox 29 is used to control the output speed. A gear distribution box 210 is fixedly installed on the base 1. The gear distribution box 210 is poweredly connected to the gearbox 29 and is used to distribute power. A motor 211 is fixedly installed at the top of the gear distribution box 210. The motor 211 is poweredly connected to the gearbox 29. A universal joint 212 is provided between the gear distribution box 210 and the cutter shaft 24. One end of the universal joint 212 is poweredly connected to the gear distribution box 210, and the other end is poweredly connected to the cutter shaft 24. A side shaft 213 is provided between the gear distribution box 210 and the upper guide roller 27. One end of the side shaft 213 is poweredly connected to the gear distribution box 210, and the other end is poweredly connected to the upper guide roller 27.

[0029] Furthermore, the gearbox 29 is existing technology. Specifically, the gearbox 29 consists of multiple large gears and multiple small gears. The large gears and small gears are arranged in a certain size and mesh with each other to form a speed-changing structure.

[0030] Furthermore, the gear distribution box 210 is existing technology. Specifically, the gear distribution box 210 is composed of multiple gears that are arranged and meshed in an alternating manner, so that the power input to the gear distribution box 210 is distributed into multiple output power.

[0031] Furthermore, the middle connecting rod of the universal joint 212 is a telescopic connecting rod, so that when the positions of the two ends of the universal joint 212 change, the middle connecting rod of the universal joint 212 automatically adapts to the length.

[0032] Furthermore, a conveyor frame 214 is fixedly installed next to the base 1. The conveyor frame 214 has an arc-shaped structure, with the top of the conveyor frame 214 facing the position of the longitudinal cutting process. Multiple conveyor rollers 215 are rotatably fitted on the conveyor frame 214. The conveyor rollers 215 are evenly distributed on the conveyor frame 214, and the upper guide roller 27 is located between the conveyor rollers 215 and the cutter shaft 24.

[0033] In the longitudinal shearing process, the alloy sheet is first conveyed onto the conveyor frame 214. The conveyor rollers 215 then continue conveying the alloy sheet into the longitudinal shearing mechanism 2. Before the alloy sheet is placed into the longitudinal shearing position, the hydraulic rod 23 is activated. The hydraulic rod 23 drives the bearing moving seat 22 to move within the vertical rail 21, causing the bearing moving seat 22 to move the cutter shaft 24 downwards. The cutter shaft 24 then drives the disc blade 25 to abut against the material support roller 26. Next, the motor 211 is activated, driving the gearbox 29 to operate. The gearbox 29 then drives the gear distribution box 210 to operate. The universal joint 212 is driven to rotate, which in turn drives the cutter shaft 24 to rotate, causing the cutter shaft 24 to drive the disc blade 25 to rotate. At the same time, the gear distribution box 210 drives the side shaft 213 to rotate, which in turn drives the upper guide roller 27 to rotate. This causes the alloy sheet on the conveying roller 215 to be conveyed between the upper guide roller 27 and the lower guide roller 28. The upper guide roller 27 and the lower guide roller 28 are used to convey the alloy sheet between the disc blade 25 and the support roller 26. Then, the disc blade 25 and the support roller 26 are used to perform longitudinal shearing on the alloy sheet. The longitudinally sheared alloy strip is then discharged from the lower guide roller 28.

[0034] Example 3, as Figures 6-10 As shown, the difference from the above embodiment is that the auxiliary mechanism 3 also includes a connecting pipe 31. The connecting pipe 31 is provided on the base 1 and is adjacent to the cutter shaft 24. Multiple dust extraction ports 32 are fixedly installed on the connecting pipe 31. The dust extraction ports 32 are evenly arranged on the connecting pipe 31 and are adjacent to each other. All dust extraction ports 32 are connected to the connecting pipe 31. Two bearing seats 33 are fixedly installed on the base 1 and are adjacent to the vertical rails 21 on each side. One end of the connecting pipe 31 is rotatably engaged with the bearing seat 33 on one side, and the other end of the connecting pipe 31 is rotatably engaged with the bearing seat 33 on the other side.

[0035] Furthermore, a spray tank 34 is fixedly installed on the base 1. The lower end of the spray tank 34 is connected to the other end of the connecting pipe 31. The spray tank 34 and the connecting pipe 31 are rotatably connected. A spray pipe 35 is fixedly installed on the spray tank 34. The spray pipe 35 penetrates the wall of the spray tank 34 and extends into the interior of the spray tank 34. The spray pipe 35 is connected to an external water supply system. The spray pipe 35 is located at the upper end of the spray tank 34. The spray pipe 35 sprays the gas. A drain pipe 36 is fixedly installed at the bottom end of the spray tank 34. The drain pipe 36 is connected to the spray tank 34. The drain pipe 36 has a U-shaped structure, which allows some of the discharged water to remain in the drain pipe 36. An air pump 37 is fixedly installed on the gear distribution box 210. The air pump 37's suction end is connected to the upper end of the spray tank 34.

[0036] Furthermore, a rail frame 38 is fixedly installed on the base 1. The rail frame 38 is adjacent to the connecting pipe 31. The length of the rail frame 38 is adapted to the length of the vertical rail 21. A rack 39 is fixedly installed on the bearing moving seat 22. The rack 39 slides with the rail frame 38. A toothed ring 310 is fixedly installed on the connecting pipe 31. The toothed ring 310 meshes with the rack 39.

[0037] During the slitting process, the air pump 37 is activated, drawing gas to create an airflow that enters the dust extraction port 32 from the slitting location. The airflow then enters the connecting pipe 31 from the dust extraction port 32, and finally enters the spray tank 34 from the connecting pipe 31. Simultaneously, the spray pipe 35 is activated, supplying water through an external water supply system to spray and remove dust from the gas entering the spray tank 34. The treated gas then enters the air pump 37 from the spray tank 34, and finally, the air pump 37 discharges the treated gas. The treated water flows into the drain pipe 36, which discharges the treated water. After the slitting process, the bearing moving seat 22... The shaft 24 and the disc blade 25 are moved upwards. The bearing moving seat 22 drives the rack 39 to move on the rail frame 38, causing the rack 39 to drive the gear ring 310 to rotate. The gear ring 310 drives the connecting pipe 31 to rotate, and the connecting pipe 31 drives the dust extraction port 32 to rotate, causing the dust extraction port 32 to deflect away from the slitting position. This ensures that the dust extraction port 32 is away from the disc blade 25, so that when there is no slitting, the dust extraction port 32 will not affect the position of the disc blade 25 during maintenance or replacement, facilitating the maintenance of the disc blade 25. During slitting, the dust extraction port 32 will also be close to the slitting position to remove dust from the area where metal dust is generated, effectively improving the health of workers.

[0038] Working principle of the invention: The alloy sheet is fed into the slitting mechanism 2, where it is slitted by the disc blade 25. Simultaneously, the dust extraction port 32 removes metal dust generated at the slitting location. When no alloy sheet is being slitted, the disc blade 25 moves upward to move away from the slitting position. As the disc blade 25 moves upward, the dust extraction port 32 is simultaneously deflected away from the slitting position, facilitating the removal of the disc blade 25. During maintenance and when the alloy sheet is re-fed, the disc blade 25 moves down to the slitting position. Simultaneously, the disc blade 25 controls the dust extraction port 32 to deflect to the side of the slitting position. This allows the dust extraction port 32 to directly remove dust at the location where the metal dust is generated during the slitting process. As a result, the metal dust generated during the slitting of the alloy sheet is simultaneously removed, reducing safety hazards for workers during the slitting of the alloy sheet and indirectly improving the safety of the equipment. In the longitudinal shearing process, the alloy sheet is first conveyed onto the conveyor frame 214. The conveyor rollers 215 then continue conveying the alloy sheet into the longitudinal shearing mechanism 2. Before the alloy sheet is placed into the longitudinal shearing position, the hydraulic rod 23 is activated. The hydraulic rod 23 drives the bearing moving seat 22 to move within the vertical rail 21, causing the bearing moving seat 22 to move the cutter shaft 24 downwards. The cutter shaft 24 then drives the disc blade 25 to abut against the material support roller 26. Next, the motor 211 is activated, driving the gearbox 29 to operate. The gearbox 29 then drives the gear distribution box 210 to operate. The universal joint 212 is driven to rotate, which in turn drives the cutter shaft 24 to rotate, causing the cutter shaft 24 to drive the disc blade 25 to rotate. At the same time, the gear distribution box 210 drives the side shaft 213 to rotate, which in turn drives the upper guide roller 27 to rotate, so that the alloy sheet on the conveying roller 215 is conveyed between the upper guide roller 27 and the lower guide roller 28. The upper guide roller 27 and the lower guide roller 28 are used to convey the alloy sheet between the disc blade 25 and the support roller 26. Then, the disc blade 25 and the support roller 26 are used to slit the alloy sheet. The slit alloy strip is then discharged from the lower guide roller 28. During the slitting process, the air pump 37 is activated, drawing gas to create an airflow that enters the dust extraction port 32 from the slitting position. The airflow then enters the connecting pipe 31 from the dust extraction port 32, and then enters the spray tank 34 from the connecting pipe 31. Simultaneously, the spray pipe 35 is activated, supplying water through an external water supply system to spray and remove dust from the gas entering the spray tank 34. The treated gas then enters the air pump 37 from the spray tank 34, and finally, the air pump 37 discharges the treated gas. The treated water flows into the drain pipe 36, which discharges the treated water. After the slitting process, the bearing moving seat 22 drives... The cutter shaft 24 and the disc blade 25 move upwards, and the bearing moving seat 22 drives the rack 39 to move on the rail frame 38, causing the rack 39 to drive the gear ring 310 to rotate. The gear ring 310 drives the connecting pipe 31 to rotate, and the connecting pipe 31 drives the dust extraction port 32 to rotate, causing the dust extraction port 32 to deflect away from the longitudinal shearing position, so that the dust extraction port 32 is away from the disc blade 25. When longitudinal shearing is not performed, the dust extraction port 32 will not affect the position of the disc blade 25 during maintenance or replacement, which is convenient for the maintenance of the disc blade 25. When longitudinal shearing is performed, the dust extraction port 32 will also be close to the longitudinal shearing position to remove dust from the place where metal dust is generated, effectively improving the health of workers.

[0039] One method, using the aforementioned 5G communication connector copper-nickel-silicon alloy strip fabrication system, includes the following steps: S1: The alloy sheet is fed into the slitting mechanism 2; S2: Use disc blade 25 to perform longitudinal shearing on alloy sheet; S3: During the longitudinal shearing process, the dust extraction port 32 removes the metal dust generated at the longitudinal shearing location.
