Detailed Implementation

[0035] 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.

[0036] An installation and cooling system for an enameled flat wire drawing die, such as Figure 1 and Figure 2 and Figure 3 and Figure 4 The device includes a box 2 installed on the wire drawing machine 1 and filled with wire drawing liquid. A fixing box 21 is provided above the opposite sides of the box 2. An installation bucket 3 is provided on one side of the fixing box 21. A mold 31 located in the installation bucket 3 is snapped onto the installation bucket 3 by a snap-fit ​​mechanism. Both the box 2 and the fixing box 21 are provided with an inlet 22 and an outlet 23. The outlet 23 on the fixing box 21 is connected to the bottom of the installation bucket 3.

[0037] The housing 2 is equipped with a lubrication and cooling mechanism, which is used to cool the opposite sides and the periphery of the mold 31 in the mounting bucket 3 through the drawing fluid in the housing 2, and at the same time lubricate the metal wire entering the mold 31.

[0038] like Figure 1 and Figure 2 and Figure 3 and Figure 4The installation bucket 3 fixes the mold 31 through a snap-fit ​​mechanism, which realizes the quick installation and disassembly of the mold 31 without the need for multiple sets of bolts. The lubrication and cooling mechanism circulates the wire drawing fluid in the box 2 into the mold 31 in the installation bucket 3, which improves the cooling effect of the mold 31. At the same time, the lubrication and cooling mechanism lubricates the metal wires that pass through the wire drawing fluid, which improves the processing quality and the life of the mold 31.

[0039] like Figure 2 and Figure 3 and Figure 4 The mold 31 is circular in shape. The locking mechanism includes a screw cap 32 threaded to the opening of the mounting barrel 3 and a pad 33 located at the bottom of the mounting barrel 3. The pad 33 is connected to the outlet 23 on the fixing box 21. The mold 31 is coaxially located in the mounting barrel 3 and abuts against the pad 33. The screw cap 32 closes the opening of the mounting barrel 3, and the screw cap 32 has a connecting groove 321 corresponding to the mold 31. Several liquid channels 34 are provided on the inner wall of the mounting barrel 3 along the length of the mounting barrel, and each liquid channel... The channels 34 are evenly distributed around the circumference of the mounting barrel 3. The cap 32 is provided with a retaining ring 322 that abuts against the opening of the mounting barrel 3. Each liquid channel 34 is connected to the inner side of the retaining ring 322. A threaded cylinder 323 is threadedly connected in the connecting groove 321. Several pressure plates 324 that abut against the mold 31 are provided on the side of the threaded cylinder 323 near the mold 31. Each pressure plate 324 is evenly distributed around the circumference of the threaded cylinder 323. The lubrication and cooling mechanism is used to introduce the drawing liquid between the mold 31 and the bottom of the mounting barrel 3.

[0040] like Figure 2 and Figure 3 and Figure 4 When in use, the circular mold 31 is coaxially placed into the installation barrel 3, so that its bottom is in close contact with the pad 33 at the bottom of the installation barrel 3. Then, the screw cap 32 is threaded onto the opening of the installation barrel 3 until the retaining ring 322 on the screw cap 32 is pressed against the end face of the opening of the installation barrel 3. At this time, several liquid channels 34 evenly distributed circumferentially on the inner wall of the installation barrel 3 are connected to the inner space of the retaining ring 322, forming an annular cavity for the flow of drawing liquid. Then, the threaded cylinder 323 is screwed into the connecting groove 321 on the screw cap 32 until each pressure plate 324 on the threaded cylinder presses against the side of the mold 31 away from the pad 33, so as to achieve radial fixation and centered clamping of the mold 31 in the installation barrel 3. At this time, the installation of the mold 31 is completed.

[0041] When the lubrication and cooling mechanism is working, the lubrication and cooling mechanism pumps the drawing fluid from the box 2 into the space between the mold 31 and the bottom of the mounting barrel 3 inside the mounting barrel 3. Then the drawing fluid is discharged into the inner side of the retaining ring 322 through the circumferential liquid channel 34 on the inner wall of the mounting barrel 3. After that, the drawing fluid enters the threaded cylinder 323 from between two adjacent pressure plates 324 and is discharged into the fixed box 21 through the threaded cylinder 323. When the liquid level of the drawing fluid in the fixed box 21 is higher than the outlet 23 on the fixed box 21, the drawing fluid will flow back to the box 2 to form a cycle.

[0042] This clamping mechanism not only enables the quick clamping of the mold 31, but also, through the structural cooperation between the liquid channel 34 and the retaining ring 322, allows the drawing fluid to surround the mold 31, thereby improving the cooling effect.

[0043] like Figure 2 and Figure 3 and Figure 4 The lubrication and cooling mechanism includes a distribution box 4 and a nozzle 41. The distribution box 4 is hollow and located on one side of the inner wall of the fixed box 21. The nozzle 41 is located on the distribution box 4 and communicates with it, with the end of the nozzle 41 away from the distribution box 4 facing the mold 31. A conduit 42 is connected to the distribution box 4, with the end of the conduit 42 away from the distribution box 4 communicating with the mounting bucket 3. The end of the conduit 42 communicating with the mounting bucket 3 is located directly above the pad cylinder 33. A water suction pipe 43 is provided on the distribution box 4, with the end of the water suction pipe 43 away from the fixed box 21 passing through the fixed box 21 and located in the drawing liquid inside the box 2. A water pump 44 is provided on the water suction pipe 43. A filter mechanism is provided on the box 2. The filter mechanism is used for... The drawing liquid entering the water pumping pipe 43 is filtered by the filtration mechanism to reduce the amount of impurities in the drawing liquid entering the water pumping pipe 43, thereby preventing the nozzle 41 and the liquid channel 34 from clogging. The water pump 44 is started, and the water pump 44 draws the drawing liquid into the distribution box 4 through the water pumping pipe 43. Then the drawing liquid in the distribution box 4 flows out through the nozzle 41 and the guide tube 42. At this time, the nozzle 41 sprays the drawing liquid onto the metal wire entering the mold 31, which can lubricate the metal wire and facilitate the drawing operation of the metal wire through the mold 31. The guide tube 42 guides the drawing liquid in the distribution box 4 into the space between the mold 31 and the bottom of the installation tank 3.

[0044] like Figure 2 and Figure 3 and Figure 6 and Figure 7 and Figure 8The water pump 43 includes a flexible hose 431 and a vertical pipe 432 connected to the flexible hose 431. The flexible hose 431 is connected to the distribution box 4. The water pump 44 is installed on the vertical pipe 432. The filtration mechanism includes a filter box 5 installed in the housing 2 via a moving mechanism and several connecting holes 51 opened in the middle of one side of the filter box 5. The top of the filter box 5 is located above the surface of the drawing liquid in the housing 2. Each connecting hole 51 is located in the drawing liquid. The bottom end of the vertical pipe 432 passes through the wall of the filter box 5 and extends to the lower part of the filter box 5. The filter box 5 rotates... Four rotating rollers 52 are connected, and the four rotating rollers 52 are paired and located at the upper and lower ends of the filter box 5 respectively. The four rotating rollers 52 are connected by a filter belt 53. At this time, the filter box 5 is located in the filter belt 53. The filter belt 53 is in contact with the side of the filter box 5 where the connecting hole 51 is provided, and the filter belt 53 closes each connecting hole 51. The filter box 5 is provided with a drive mechanism for driving one of the rotating rollers 52 to rotate. The top of the filter box 5 is provided with a scraping mechanism for scraping impurities on the filter belt 53. The moving mechanism is used to drive the filter box 5 to move vertically up and down.

[0045] The drive mechanism includes a slide plate 542 and a mounting bracket 54 located at the top of the filter box 5. The mounting bracket 54 is inverted L-shaped and has two vertically mounted slide rails 541. The slide plate 542 is vertically slidably connected to the two slide rails 541. The bottom of the slide plate 542 has two side frames 543, and a pressure shaft 544 is rotatably connected between the two side frames 543. The pressure shaft 544 is located above one of the rotating rollers 52 and abuts against the filter belt 53. The pressure shaft 544 has two opposing limiting rings 545. The filter belt 53 is located between the two limiting rings 545 and in contact with the limiting rings 545. The top of the filter box 5 has a motor 55. The rotating shaft of the motor 55 is used to drive the rotating roller 52 located below the pressure shaft 544 to rotate. A tension spring 546 is provided between the bottom of the slide plate 542 and the mounting bracket 54. The filter box 5 has a pressure sensor 6, and the pressure sensor 6 controls the operation of the motor 55.

[0046] like Figure 2 and Figure 3 and Figure 6 and Figure 7 and Figure 8 By starting the motor 55, the rotating shaft of the motor 55 can drive the rotating roller 52 located below the pressure shaft 544 to rotate, thereby driving the entire filter belt 53 to start circulating. When the filter belt 53 is pressed against the rotating shaft below the pressure shaft 544, the tension spring 546 is in a stretched state. At this time, by pressing the filter belt 53 against the rotating shaft below the pressure shaft 544, the slippage between the rotating shaft and the filter belt 53 when the rotating shaft of the motor 55 drives the rotating roller 52 located below the pressure shaft 544 to rotate can be reduced.

[0047] The filter box 5 is pre-filled with clean drawing liquid. When the water pump 44 is started, the pump can immediately draw liquid from the box. At this time, the drawing liquid in the box 2 flows into the filter box 5 through the connecting hole 51 on the side wall of the filter box 5 under the action of pressure difference. When the drawing liquid flows into the filter box 5 through the connecting hole 51, it first passes through the filter belt 53 wrapped around the box. The impurities in it are intercepted by the filter belt 53. The clean drawing liquid passes through the filter belt 53 and flows into the filter box 5 through the connecting hole 51. Under normal conditions, the motor 55 is in standby mode and the filter belt 53 remains stationary.

[0048] As impurities gradually accumulate on the outer surface of the filter belt 53, the permeability of the filter belt 53 decreases, resulting in a decrease in the internal pressure of the filter box 5. When the pressure sensor 6 installed inside the box detects that the pressure value reaches the preset blockage alarm threshold, it is determined that the filter belt 53 is blocked. The pressure sensor 6 then controls the motor 55 of the drive mechanism to start. After the motor 55 starts, the rotating shaft of the motor 55 drives one of the rollers 52 to rotate, causing the entire filter belt 53 to start cyclically moving until the blocked area of ​​the filter belt 53 is removed. The new clean filter belt 53 area moves to the position of the connecting hole 51, restoring the filtration capacity. At this time, the internal pressure of the filter box 5 gradually returns to the preset normal value. When the pressure sensor 6 detects that the pressure has returned to the preset normal setting range, it is determined that the blockage has been resolved. Then, it controls the motor 55 to stop working, and the filter belt 53 enters the static filtration state again. This cycle is repeated to achieve automatic intermittent operation of blockage-start-stop-blockage-start-stop.

[0049] When the filter belt 53 with impurities moves to the top of the filter box 5 and passes the scraping mechanism, the scraper 547 scrapes off the impurities, completing the self-cleaning process.

[0050] like Figure 8 The filter box 5 has two vertical strips 56 on the side wall with the connecting holes 51. The filter belt 53, which closes each connecting hole 51, is located between the two vertical strips 56 and in contact with the two vertical strips 56. The vertical strip 56 near the moving mechanism is fixedly connected to the filter box 5, and the other vertical strip 56 is detachably connected to the filter box 5. When the filter belt 53 needs to be replaced, the filter box 5 is moved upward out of the housing 2 by the moving mechanism. Then the detachable vertical strip 56 is removed from the filter box 5, and the sliding plate 542 is pushed upward to release the pressure of the pressure shaft 544 on the filter belt 53. After that, the filter belt 53 can be removed from the filter box 5 and the four rotating rollers 52 for replacement. The disassembly and assembly are simple.

[0051] like Figure 8 and Figure 9 A vertical groove 57 is used on one side of the filter box 5, and a slider 571 is vertically connected in the groove 57. The groove 57 is connected to the top of the filter box 5, and the detachable upright strip 56 of the filter box 5 is set on the slider 571. When disassembling, simply pull the upright strip 56 vertically upward.

[0052] like Figure 2 and Figure 5 The moving mechanism includes a moving frame 58 set at the top of the filter box 5. The moving frame 58 is inverted U-shaped. An electric cylinder 24 is provided on one side of the outer wall of the box 2 to push the moving frame 58 to move vertically. By activating the electric cylinder 24, the piston rod of the electric cylinder 24 drives the filter box 5 to move upward through the moving frame 58 until the filter box 5 is moved out of the box 2. At this time, it is convenient to replace the filter belt 53.

[0053] like Figure 6 The scraping mechanism includes a scraper 547 and a placement frame 59 located at the top of the filter box 5. The placement frame 59 is located in the filter belt 53 and contacts the inner top of the filter belt 53. The scraper 547 is installed at an angle below the mounting frame 54 through an adjustment mechanism, and the bottom end of the scraper 547 contacts the outer top of the filter belt 53. A collection box 591 is placed at the top of the filter box 5. The scraper 547 is used to scrape impurities on the filter belt 53 into the collection box 591. When the part of the filter belt 53 with impurities moves to the top of the filter box 5 and passes through the scraping mechanism, the impurities on the filter belt 53 will be scraped off by the scraper 547 and collected in the collection box 591. The tilt angle of the scraper 547 on the filter belt 53 can be adjusted as needed through the adjustment mechanism. When the angle is steeper, the scraping force is stronger and it is suitable for removing firmly attached impurities. When the angle is gentler, the scraping is more gentle and helps to reduce wear on the filter belt 53 material.

[0054] like Figure 6 and Figure 10 and Figure 11The adjusting mechanism includes a threaded hole 548 on the mounting bracket 54 and a screw 5481 threaded into the threaded hole 548. The bottom end of the screw 5481 is rotatably connected to the top end of the scraper 547. An adjusting column 5471 is vertically provided at the top end of the scraper 547. The mounting bracket 54 has an arc-shaped groove 549 for the top end of the adjusting column 5471 to pass vertically through. When the scraper 547 rotates along the rotation point of the screw 5481 and the scraper 547, the adjusting column 5471 slides in the arc-shaped groove 549 along the arc direction of the arc-shaped groove 549. The mounting bracket 54 has a limiting member for restricting the sliding of the adjusting column 5471 in the arc-shaped groove 549. The limiting member includes a fixed seat 7. The slide 71 and several limiting rods 711 are provided on one side of the slide 71. Each limiting rod 711 is distributed at intervals along the length of the slide 71 and is integrally formed with the slide 71. The fixed seat 7 is set on the mounting bracket 54. The slide 71 is located on the side of the fixed seat 7 near the arc groove 549. Two sliding columns 712 are horizontally provided on the side of the slide 71 near the fixed seat 7. Two circular grooves 72 are provided on the fixed seat 7 for one end of each of the two sliding columns 712 to pass horizontally through. A compression spring 73 is provided between the slide 71 and the fixed seat 7. The top end of the adjusting column 5471 passes between two adjacent limiting rods 711. At this time, the adjusting column contacts the side wall of the limiting rod 711.

[0055] like Figure 6 and Figure 10 and Figure 11 When it is necessary to adjust the tilt angle of scraper 547, push slide 71 close to fixed seat 7 to compress compression spring 73 located between slide 71 and fixed seat 7. As slide 71 moves horizontally, several limit rods 711 fixed on slide 71 also move synchronously until adjustment column 5471 moves out from between two adjacent limit rods 711, so that the sliding path of adjustment column 5471 in arc groove 549 is released, releasing the mechanical lock on the rotation of scraper 547. Then, the tilt angle of scraper 547 on filter belt 53 can be adjusted as needed.

[0056] When the scraper 547 is adjusted to the correct angle and the adjusting column 5471 corresponds to two adjacent limit rods 711, the slide 71 is released. At this time, the compressed spring releases its elastic force, pushing the slide 71 to reset away from the fixed seat 7, so that the adjusting column 5471 can enter between two adjacent limit rods 711. It is simple and convenient to use.

[0057] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
