Description

Technical Field

[0001] The invention belongs to the technical field of alloy resistance wire preparation, and in particular relates to a wire drawing device for preparing alloy resistance wire. Background Art

[0002] Alloy resistance wire is a resistance material made of an alloy composed of two or more different metal elements. This resistance wire usually has a higher resistivity than ordinary metals, so it can be used to make electronic components such as resistors. The resistivity of alloy resistance wire can be adjusted by the selection and proportion of alloy elements to meet the requirements of different circuit designs. As we all know, the resistance of a material is determined by the properties and cross-sectional area of ​​the material itself. Therefore, in order to achieve a suitable resistance value, the thickness of the alloy resistance wire is also crucial. In order to change the thickness of the alloy resistance wire, it needs to be processed by a wire drawing machine.

[0003] The main purpose of wire drawing is to precisely control the diameter and shape of alloy resistance wires, as well as to improve their mechanical properties and surface quality. Through wire drawing, the diameter of the alloy resistance wire can be precisely controlled to ensure that it meets the design requirements so that it can be used normally in electronic components. Wire drawing can make the metallographic structure of the alloy resistance wire more uniform, thereby improving the stability and consistency of its resistivity. At the same time, it can improve the surface quality of the alloy resistance wire, reduce surface defects and oxide layers, thereby improving its corrosion resistance and electrical conductivity. After wire drawing, the grains of the alloy resistance wire are refined and the structure is more compact, thereby improving its mechanical strength and ductility.

[0004] The existing wire drawing machines require the alloy resistance wire to be processed through several wire drawing dies, which can effectively avoid the metal wire breakage caused by excessive diameter reduction. However, when the alloy resistance wire passes through the wire drawing die, workers need to manually process the thickness of the alloy resistance wire with a file so that the alloy resistance wire can pass through the wire drawing die. Multiple wire drawing dies will lead to greater work intensity. At the same time, manual adjustment will result in too long preparation time before processing, which is not conducive to large-scale production. At the same time, since the wire drawing die reduces the diameter of the resistance wire through friction and extrusion, a large amount of heat will be generated. In order to avoid the heat from being unable to dissipate in time, the speed of the alloy resistance wire during the wire drawing process is slow and the production efficiency is low.

A sponge is placed in the fixed groove, so that the alloy resistance wire is cleaned by the sponge at the guide groove before drawing. The coolant accumulates in the water tank, and the excess liquid is discharged through the drain hole. The debris generated by the alloy resistance wire during the processing falls into the water tank. Due to the large density of the debris, it will settle in the collection box.

[0017] Furthermore, the transmission shaft passes through a sliding connection strip hole, and a driven synchronous wheel is fixedly connected to one side of the first driven roller, and a synchronous belt is sleeved on the outside of the driven synchronous wheel and the active synchronous wheel, and a third driven roller is rotatably connected between an end of the rotating frame away from the first driven roller, and a blocking rod is fixedly connected to both sides of the rotating frame, a shift rod is fixedly connected to one side of the rotating frame, and a second fixed rod is fixedly connected to one side of the rotating frame, and a first fixed rod is rotatably connected to one side of the second bracket, and a tension spring is fixedly connected to the first fixed rod, and an end of the tension spring away from the first fixed rod is fixedly connected to the second fixed rod, and a guide tube is fixedly connected to a side of the mounting plate close to the support frame, and sandpaper is provided on the outer sleeve of the third driven roller.

[0018] Through the above technical scheme, the active roller drives the active synchronous wheel to rotate, the active synchronous wheel drives the driven synchronous wheel to rotate through the synchronous belt, the driven synchronous wheel drives the first driven roller to rotate, the first driven roller drives the sandpaper to rotate, and the alloy resistance wire is polished by the sandpaper, so that the head of the alloy resistance wire can easily pass through the wire drawing die, and through the setting of the tension spring and the stop rod, the rotating frame can be fixed by the tension of the tension spring and the blocking of the stop rod when flipping up or down.

[0020] Through the above technical solution, when the cylinder drives the wire drawing drum to move outward, the second spring pushes the inner sleeve to move in the direction of the wire drawing die, so that the steel ball is limited by the wire drawing drum and pushed inward, and the steel ball moves inward to clamp the alloy resistance wire, so that the alloy resistance wire is pulled through the wire drawing die, and then the cylinder drives the second connecting rod to return, and the alloy resistance wire pushes the steel ball in the direction of the second spring, so that the inner sleeve compresses the second spring, and the steel ball is no longer restricted by the wire drawing drum, thereby releasing the lock on the alloy resistance wire, and this process is repeated, so that the alloy resistance wire is continuously pulled out.

[0021] Furthermore, the wire drawing die includes a main body rotatably connected to a water tank, a groove is provided on the outside of the main body, a driven gear is fixedly connected to one end of the main body close to the groove, a plurality of fins are fixedly connected to the outside of the main body, a plurality of baffles are fixedly connected to the outside of the main body, and the driven gear and the transmission gear are meshed with each other.

[0022] Through the above technical solution, the transmission gear and the driven gear cooperate to drive the main body to rotate, and the main body rotates with the baffle, and the baffle drives the coolant in the water tank to be thrown up, so that the coolant covers the fins, thereby greatly improving the heat dissipation capacity of the wire drawing die.

[0023] The beneficial effects of the present invention are as follows: (1) The present invention uses a wire feeding pretreatment mechanism. When feeding the wire, the worker inserts the resistance wire between the active roller and the second driven roller, so that the resistance wire is clamped by the active roller and the second driven roller. Then the fifth motor drives the active roller to rotate, and the active roller drives the first driven roller to rotate, so that the resistance wire moves toward the wire drawing die, and the sandpaper rotates to grind the front section of the resistance wire, so that it is convenient for the resistance wire to be inserted into the wire drawing die. After the resistance wire is inserted into the wire drawing die, the rotating frame is flipped up by the lever so that the sandpaper no longer contacts the resistance wire. The setting of this mechanism can complete automatic wire feeding and pretreatment, reducing the labor intensity of workers; (2) The present invention uses the setting of the wire drawing mechanism. When the resistance wire passes through the wire drawing die, a pointed head will emerge, and this pointed head enters the inner sleeve. Then the cylinder drives the wire drawing drum to move outward, the second spring pushes the inner sleeve to move, and the inner sleeve drives the steel balls to move. The steel balls move inward under the restriction of the wire drawing drum, clamp the pointed head, and thus drive the resistance wire to pass through the wire drawing die. When the cylinder drives the wire drawing drum back to its original position, the pointed head pushes the steel ball to move, so that the steel ball drives the inner sleeve to move outward, so that the steel ball is not restricted by the wire drawing drum, and the pointed head can move in the inner sleeve. In this way, the resistance wire can be pulled out a long distance by reciprocating, which is convenient for workers to wind the wire on the guide roller. Compared with the existing method of clamping the wire with pointed pliers, the labor intensity is greatly reduced; (3) The present invention uses a support frame to drive the transmission gear to rotate through the third motor, so that the wire drawing die rotates, and the water storage tank can accumulate the coolant sprayed from the nozzle. When the wire drawing die rotates, the baffle throws the coolant up, so that the fins can fully contact the coolant, so that the wire drawing die can better dissipate heat during operation, thereby accelerating the movement speed of the resistance wire and improving work efficiency. At the same time, through the use of the bottom collection box, the debris generated during the wire drawing process can be collected and returned to the furnace for re-smelting, which effectively improves the utilization rate of the material and avoids waste.

Then the cylinder 72 drives the second connecting rod 73 to return, and the alloy resistance wire pushes the steel ball 78 in the direction of the second spring 75, so that the inner sleeve 76 compresses the second spring 75, and the steel ball 78 is no longer restricted by the wire drawing cylinder 74, thereby releasing the lock on the alloy resistance wire. This is repeated so that the alloy resistance wire is continuously pulled out.

[0050] like Fig.10 As shown, a plurality of wire drawing dies 8 are rotatably connected inside the support frame 5, and the wire drawing dies 8 include a main body 81 rotatably connected to the water storage tank 51, a groove 84 is provided on the outside of the main body 81, and a driven gear 85 is fixedly connected to one end of the main body 81 close to the groove 84, a plurality of fins 82 are fixedly connected outside the main body 81, a plurality of baffles 83 are fixedly connected outside the main body 81, the driven gear 85 and the transmission gear 513 are meshed with each other, and the main body 81 rotates with the baffle 83, and the baffle 83 drives the coolant in the water storage tank 51 to be thrown up, so that the coolant covers the fins 82, thereby greatly improving the heat dissipation capacity of the wire drawing die 8.

[0051] The working principle of this embodiment is as follows: first, the hook 53 is separated from the post 54, the upper clamp block 52 is flipped up and opened, and the wire drawing die 8 is placed from the inside to the outside in the order of aperture from large to small, so that the groove 84 is aligned with the corresponding depression on one side of the water storage tank 51, and then the upper clamp block 52 is lowered, so that the hook 53 hooks the post 54 again, and then the staff loosens the fixing bolt 33, so that the sliding seat 32 drives the wire-releasing roller 34 to move on the support rod 31 and adjust it to a suitable position, and then tightens the fixing bolt 33, pulls out the alloy resistance wire on the wire-releasing roller 34, and sends it between the active roller 611 and the second driven roller 620, and the first spring 61 6 pushes the bottom plate 617 downward, and the bottom plate 617 drives the second driven roller 620 to press downward through the lifting frame 618, so that the second driven roller 620 and the active roller 611 clamp the alloy resistance wire, and the fifth motor 69 drives the active roller 611 to rotate through the transmission shaft 610, so that the alloy resistance wire moves toward the guide tube 628. At this time, the active roller 611 drives the active synchronous wheel 612 to rotate, and the active synchronous wheel 612 drives the driven synchronous wheel 614 to rotate through the synchronous belt 615, and the driven synchronous wheel 614 drives the first driven roller 613 to rotate, and the first driven roller 613 drives the sandpaper 629 to rotate, and the sandpaper 629 is used to press the alloy resistance wire. The resistance wire is polished so that the head of the alloy resistance wire can easily pass through the wire drawing die 8. After the head of the alloy resistance wire passes through the wire drawing die 8, the staff drives the rotating frame 621 to flip up through the lever 627. When the tension spring 624 rotates past the longest point, the tension spring 624 drives the rotating frame 621 to automatically flip up, and through the cooperation of the stop rod 622 and the second bracket 68, the rotating frame 621 is fixed in the flipped position to prevent the sandpaper 629 from continuing to polish the alloy resistance wire. After that, the head of the alloy resistance wire will enter the inner sleeve 76, and then the cylinder 72 drives the second connecting rod 73 to pull outward, so that the second connecting rod 73 drives the drawing die 76 to rotate. The wire drum 74 moves outwards. When the wire drawing drum 74 moves outwards, the second spring 75 pushes the inner sleeve 76 to move in the direction of the wire drawing die 8, so that the steel ball 78 is limited by the wire drawing drum 74 and pushed inwards. The steel ball 78 moves inwards to clamp the alloy resistance wire, so that the alloy resistance wire is pulled through the wire drawing die 8. Then, the cylinder 72 drives the second connecting rod 73 to return, and the alloy resistance wire pushes the steel ball 78 in the direction of the second spring 75, so that the inner sleeve 76 compresses the second spring 75, and the steel ball 78 is no longer limited by the wire drawing drum 74, thereby releasing the lock on the alloy resistance wire, and this is repeated, so that the alloy resistance wire is continuously pulled out;

[0052] Subsequently, the alloy resistance wire passing through the wire drawing die 8 is wound around the second guide roller 27 and rewound onto the first guide roller 26. The alloy resistance wire rewound onto the first guide roller 26 is aligned with the next wire drawing die 8 and inserted. This process is repeated. The alloy resistance wire processed by the wire drawing dies 8 with multiple different apertures passes through the fixing hole 45 and is knotted, so that the alloy resistance wire is fixed on the fixing plate 44. Then, the pipeline 24 is rotated to the top of the support frame 5. The coolant in the water tank 22 is pumped into the pipeline 24 by the water pump 23 and sprayed out through the nozzle 25 to cool the wire drawing die 8.

[0053] Afterwards, the fourth motor 62 drives the lead screw 63 to rotate, and the lead screw 63 drives the first connecting rod 65 to move outward along the guide rod 64, and a sponge is placed in the fixed groove 57, so that the alloy resistance wire is cleaned by the sponge at the guide groove 58 before drawing. During the wire drawing operation, the second guide roller 27 is driven to rotate by the first motor 28, and the winding roller 43 is driven to rotate by the second motor 42, so that the alloy resistance wire continuously passes through the wire drawing die 8 and is wound around the winding roller 43;

[0054] The coolant accumulates in the water tank 51, and the excess liquid is discharged through the drainage hole 59. The third motor 512 drives the transmission gear 513 to rotate, and the transmission gear 513 cooperates with the driven gear 85 to drive the main body 81 to rotate. The main body 81 rotates with the baffle 83, and the baffle 83 drives the coolant in the water tank 51 to be thrown up, so that the coolant covers the fins 82, thereby greatly improving the heat dissipation capacity of the wire drawing die 8, so that the wire drawing speed can be accelerated and the processing efficiency is improved. During the processing, the debris generated by the alloy resistance wire falls into the water tank 51. Due to the large density of the debris, it will settle in the collection box 55. After the processing is completed, the collection box 55 is pulled out by the handle 56, so that the coolant leaks out through the water leakage net 510, and all the outflowing coolant enters the water collecting tank 9, and then enters the drain port 10 and is discharged through the drain pipe 11.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
