Description

Technical Field

[0001] The invention relates to the field of silver-plated copper wire processing equipment, in particular to a silver-plated copper wire auxiliary stretching equipment. Background Art

[0002] Silver-plated copper wire is a thin wire made by silver-plating oxygen-free copper wire or low-oxygen copper wire and then drawing it through a wire drawing machine. This wire has excellent electrical conductivity, thermal conductivity, corrosion resistance and high-temperature oxidation resistance, and is widely used in electronics, communications, aerospace, military and other fields. The silver-plated layer can reduce the contact resistance of the metal surface and improve the welding performance. At the same time, silver has high chemical stability and can resist corrosion from alkali and some organic acids. It does not react with oxygen in general air. In addition, silver is easy to polish and has a strong reflective ability. Therefore, the silver-plated layer is also often used in the decoration of tableware, musical instruments, jewelry and various crafts.

[0003] After the silver-plated copper wire is stretched, its diameter decreases, its length increases, and its surface finish and internal structure are improved, which is beneficial to reduce resistivity and improve signal transmission efficiency and quality. For different usage requirements, the diameter of the silver-plated copper wire is different, so it is necessary to replace the mold for stretching. Moreover, for some smaller diameter requirements, a single stretching cannot directly obtain the target diameter. Multiple stretchings are required, which requires multiple replacements of the mold. Moreover, the silver-plated copper wire needs to be lubricated before stretching. The current stretching equipment soaks the silver-plated copper wire in lubricating liquid, and there is enough lubricating oil attached to the surface after passing through. However, the silver-plated copper wire may have impurities. After processing for a period of time, the lubricating oil is contaminated. When passing through the mold, impurities may damage the surface of the silver-plated copper wire, affecting the performance of the silver-plated copper wire, and the consumption of lubricating oil is large.

DETAILED DESCRIPTION

[0026] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0027] Embodiment: A silver-plated copper wire auxiliary stretching device, such as Figure 1-Figure 4 As shown, it includes a workbench 1, a motor 11, a winding roller 12, a winding wheel 13 and a sleeve plate 14. The motor 11 is installed at the rear end of the workbench 1. The output shaft of the motor 11 is connected to the winding roller 12. Three winding wheels 13 are slidably connected to the winding roller 12, which can stretch three silver-plated copper wires at the same time. The sleeve plate 14 is clamped at the rear end of the workbench 1. The sleeve plate 14 is hinged to the other end of the winding roller 12. For details, refer to Fig. 9 The winding roller 12 is provided with a convex rod, and the winding wheel 13 is provided with a matching groove to limit the winding wheel 13 from rotating on the winding roller 12, so that when the winding roller 12 drives the winding wheel 13 to rotate, no deflection occurs. However, the end of the winding roller 12 connected to the sleeve plate 14 is not provided with a convex rod, and can be used for hinge connection. It also includes a replacement mechanism 2, a lubricating mechanism 3 and a fixing mechanism 4. A replacement mechanism 2 for replacing the stretching mold 221 is provided on the workbench 1, a lubricating mechanism 3 for applying oil is provided at the front end of the workbench 1, and a fixing mechanism 4 for limiting the replacement mechanism 2 from replacing the mold is provided on the workbench 1.

[0028] like Figure 3-Figure 5As shown, the replacement mechanism 2 includes a support frame 21, a mold wheel 22, a stretching mold 221 and a rotating wheel 23. Two support frames 21 are connected to the left and right sides of the workbench 1. Four adjacent support frames 21 are grouped in pairs. A mold wheel 22 is rotatably connected between two support frames 21 with the same front and rear positions. Twelve stretching molds 221 are installed on the mold wheel 22, and the apertures of the stretching molds 221 on the front mold wheel 22 are larger than the apertures of the stretching molds 221 on the rear mold wheel 22. Rotating wheels 23 are connected to both ends of the mold wheel 22.

[0029] like Figure 3 , Figure 4 and Figure 6 As shown, the lubrication mechanism 3 includes a support rod 31, an oil tank 32, an oil inlet nozzle 321, an oil outlet nozzle 322, a rotating shaft 33, a belt 34, a pulley 35, a limiting roller 36 and a lubricating sleeve 37. The support rod 31 is connected to the left and right sides of the front end of the workbench 1, and the oil tank 32 is connected between the two support rods 31. The top of the oil tank 32 is provided with an oil inlet nozzle 321, and the bottom of the oil tank 32 is provided with an oil outlet nozzle 322. Both ends of the rotating shaft 33 are rotatably connected to the support rod 31, and the middle of the rotating shaft 33 passes through the oil tank 32. The limiting roller 36 is rotatably connected to the oil tank 32, and the limiting roller 36 is connected to the rotating shaft 33. Pulleys 35 are connected to both sides of the rotating shaft 33. The pulleys 35 are located on the outside of the oil tank 32. There is a pulley 35, and a belt 34 is wound between the two pulleys 35 aligned in front and back positions. The limiting roller 36 is provided with oil holes 361 of different sizes, and the oil holes 361 are aligned with the oil nozzle 322. The lower end of the oil nozzle 322 is connected with a lubricating sleeve 37. The diameter of the opening at the front end of the lubricating sleeve 37 is smaller than the silver-plated copper wire, and it is squeezed with the silver-plated copper wire to clean the surface of the silver-plated copper wire. The diameter of the opening at the rear end is slightly larger than the silver-plated copper wire, which can ensure the thickness of the surface lubricating oil and will not be scraped off by the lubricating sleeve 37, so that the lubricating oil can be evenly applied. A waterproof sticker is attached to the bottom of the lubricating sleeve 37, which does not absorb the lubricating oil and is used to block the passage of the lubricating oil, so that when the work stops, the lubricating oil will not drip directly from the bottom of the lubricating sleeve 37.

[0030] like Figure 3-Figure 5 As shown, the fixing mechanism 4 includes a slide rail 41, a pull rod 42 and a limiting frame 43. The slide rail 41 is connected to the workbench 1 and is located at the bottom of the mold wheel 22. The pull rod 42 is slidably connected to the slide rail 41. The top of the pull rod 42 is connected to the limiting frame 43. The limiting frame 43 is used to prevent the stretching mold 221 from rotating.

[0031] After the staff passes the silver-plated copper wire to be stretched through the lubrication mechanism 3 and the replacement mechanism 2 in turn, it is connected to the winding wheel 13 and the silver-plated copper wire is fixed. Then the motor 11 is turned on to drive the winding roller 12 to rotate, so that the silver-plated copper wire is wound around the winding wheel 13, and the silver-plated copper wire is pulled to move backward. In the middle, it passes through the replacement mechanism 2 and the lubrication mechanism 3. The lubrication mechanism 3 oils the surface of the silver-plated copper wire so that the surface can be lubricated before stretching, making the stretching process smoother. Then, through the replacement mechanism 2, according to the diameter to be stretched, a suitable mold is selected, so that it is selected through the replacement mechanism 2 and the fixing mechanism 4. The replacement mechanism 2 is fixed to prevent it from moving during the stretching process, and the stretching process is completed smoothly. When the mold needs to be replaced, the restriction on the replacement mechanism 2 needs to be released through the fixing mechanism 4. When the mold is replaced, the lubricating mechanism 3 will also follow the adjustment of the replacement mechanism 2 to change the oil output, thereby saving the use of lubricating oil while ensuring the lubrication of the silver-plated copper wire. After the stretching is completed, the motor 11 is turned off, the sleeve plate 14 is removed, and the winding wheel 13 is taken out. Since a convex rod is provided on the winding roller 12, when the winding roller 12 drives the winding wheel 13 to rotate, no deflection will occur, thereby ensuring the effectiveness of power transmission;

[0032] When replacing the stretching die 221, the staff only needs to rotate the die wheel 22 through the rotating wheel 23. Four stretching dies 221 of different specifications are installed on the die wheel 22. Through two rows of die wheels 22, a smaller diameter can be stretched at one time, and the stretching speed of a large diameter can also be made faster. In subsequent improvements, more rows can also be added according to production needs. When the silver-plated copper wire passes through the stretching die 221, it is squeezed by the stretching die 221 and enters from the circular hole with a large diameter. The aperture of the rear end of the stretching die 221 is reduced, so that after passing through, the diameter of the silver-plated copper wire becomes smaller;

[0033] The oil inlet nozzle 321 at the upper end of the oil tank 32 is connected to an oil storage device, and the oil outlet nozzle 322 at the lower end of the oil tank 32 is connected to a lubricating sleeve 37. The silver-plated copper wire needs to pass through the lubricating sleeve 37, and a limiting roller 36 is provided in the oil tank 32. The lubricating oil in the oil tank 32 needs to reach the oil outlet nozzle 322, and can only pass through the oil through port 361 of the limiting roller 36 first. The lubricating sleeve 37 receives the lubricating oil flowing out of the oil outlet nozzle 322 to lubricate the surface of the silver-plated copper wire. At the same time, when rubbing against the silver-plated copper wire, some impurities on the surface of the silver-plated copper wire can be cleaned, thereby avoiding scratches on the surface of the silver-plated copper wire during the stretching process. When the staff adjusts the stretching die 221 by replacing the mechanism 2 , the belt 34 is driven to rotate by the pulley 35 on the die wheel 22, thereby pulling the rotating shaft 33 to rotate. Since the limiting roller 36 connected to the rotating shaft 33 is provided with four oil holes 361 of different diameters, corresponding to the four stretching dies 221, when the stretching die 221 with a larger aperture at the rear end is used for stretching, the oil hole 361 with a large diameter is downward, and when the stretching die 221 with a small aperture is used for stretching, the limiting roller 36 is driven to rotate by the belt 34, and the oil hole 361 with a small diameter is downward. Therefore, the oil output is limited by the size of the oil hole 361, thereby saving the use of lubricating oil while ensuring the lubrication of the silver-plated copper wire;

[0034] When the silver-plated copper wire is stretched, the limiting frame 43 is against the stretching die 221, and the limiting die wheel 22 cannot rotate, thereby ensuring the stability of the stretching process. Before replacing the stretching die 221, push the pull rod 42 to the left, and the pull rod 42 moves the limiting frame 43 to the left, so that the limiting frame 43 leaves the stretching die 221. After rotating the die wheel 22 to complete the adjustment, pull the pull rod 42 to the right, and the pull rod 42 moves the limiting frame 43 to the right. The limiting frame 43 is against the stretching die 221, and in the process of stretching the silver-plated copper wire, there is only backward pulling force, so the stretching die 221 will fit tightly with the limiting frame 43, and the limiting frame 43 will not separate from the stretching die 221, thereby ensuring the stability of the stretching process.

[0035] like Figure 8As shown, it also includes a cleaning mechanism 5, which includes a push rod 51, a guide rod 52, a connecting frame 53, a push block 54, an elastic member 55, a cleaning rod 56 and a cleaning block 57. The limiting frame 43 is connected with the push rod 51, and the workbench 1 is connected with a plurality of guide rods 52. The connecting frame 53 is slidably connected to the plurality of guide rods 52. The bottom of the connecting frame 53 is hinged with a plurality of cleaning rods 56, and the bottom of the cleaning rod 56 is connected with a cleaning block 57. The cleaning rod 56 is aligned with the circular hole in the middle of the stretching mold 221. The connecting frame 53 is connected with a push block 54, and the push block 54 is extruded and matched with the push rod 51 to push the connecting frame 53 to slide upward along the guide rod 52. An elastic member 55 is sleeved on the top of the guide rod 52, one end of the elastic member 55 is connected to the connecting frame 53, and the other end is connected to the guide rod 52. The elastic member 55 is used to push the connecting frame 53 to slide downward along the guide rod 52 and reset. The bottom of the cleaning block 57 is conical.

[0036] If the stretching die 221 needs to be replaced, the limiting frame 43 needs to be moved, and when the pull rod 42 is pulled, the push rod 51 on the limiting frame 43 also moves accordingly. When the push rod 51 moves to the left, the push rod 51 squeezes the push block 54, causing the push block 54 to move upward, driving the connecting frame 53 to slide upward along the guide rod 52, compressing the elastic member 55, and the connecting frame 53 drives the cleaning rod 56 to move upward. The cleaning block 57 connected to the cleaning rod 56 passes through the through hole in the middle of the stretching die 221, thereby cleaning the stretching die 221, and at the same time cleaning all the stretching dies 221 in the horizontal position at the same time, removing the residual debris or burrs during the stretching process, and then rotating. When the mold wheel 22 and the stretching mold 221 come into contact with the cleaning rod 56, the cleaning rod 56 will be squeezed to rotate. Due to the gravity of the cleaning rod 56 itself, after the stretching mold 221 is replaced, the cleaning rod 56 can still maintain a vertical state, and then the pull rod 42 is pulled to the right, the push rod 51 leaves the push block 54, the elastic member 55 rebounds, the extrusion connecting frame 53 slides downward, and the cleaning rod 56 and the cleaning block 57 slide downward. Through the stretching mold 221 which is in a horizontal state at this time, if the stretching mold 221 is selected multiple times, it is rotated 180 degrees, then the 180 degrees is divided into two rotations, and the pull rod 42 is pulled twice respectively to clean all the stretching molds 221.

[0037] like Fig. 9 and Fig.10 As shown, it also includes a water frame 6, a water tank 61, a diverter pipe 62 and a nozzle 63. The water frame 6 is connected to the workbench 1, the water tank 61 is connected to the bottom of the workbench 1, the water frame 6 is connected to the diverter pipe 62, the diverter pipe 62 is connected to a plurality of nozzles 63, and the diverter pipe 62 is connected to an external water source.

[0038] like Fig. 9 and Fig.10As shown, it also includes a connecting rod 7, a connecting plate 71, a U-shaped frame 72, a rotating block 73 and a scrubbing roller 74. The connecting plate 71 is connected to the left and right sides of the top surface of the workbench 1, and the scrubbing roller 74 is rotatably connected between the connecting plates 71. The two connecting rods 7 are connected to one side of the top surface of the workbench 1, and the U-shaped frame 72 is connected to the other side of the top surface of the workbench 1. The two connecting rods 7 are rotatably connected to the rotating blocks 73, and one end of the scrubbing roller 74 is rotatably connected to the rotating block 73. The other end of the scrubbing roller 74 is supported by the U-shaped frame 72. The scrubbing roller 74 is heavy and can maintain the extrusion of the silver-plated copper wire.

[0039] When the stretched silver-plated copper wire passes through the water frame 6, the shunt pipe 62 of the external water source will spray liquid on the surface of the silver-plated copper wire through the nozzle 63 to clean the lubricating oil on the surface of the silver-plated copper wire. At the same time, chemical agents can be added to the water source to react with the lubricating oil during flushing and dissolve the lubricating oil. The chemical agents will not corrode the silver-plated layer or cause pollution to the environment. After being blocked by the water frame 6, the sprayed liquid is collected by the water tank 61. The liquid fused with the lubricating oil is then processed later to complete the cleaning. The silver-plated copper wire that has been cleaned continues to move backwards, and the silver-plated copper wire that has been cleaned passes through the scrubbing roller 74. The distance between the two scrubbing rollers 74 is smaller than the diameter of the silver-plated copper wire. When passing through the two scrubbing rollers 74, the upper scrubbing roller 74 is lifted. When the scrubbing roller 74 is lifted, the rotating block 73 rotates around the connecting plate 71, the bottom scrubbing roller 74 rotates on the connecting rod 7, and the top scrubbing roller 74 rotates on the U-shaped frame 72 and the rotating block 73 to clean the liquid remaining on the surface of the silver-plated copper wire.
