Description

Technical Field

[0001] The invention relates to the technical field of stainless steel fine wire die drawing, and more particularly to a stainless steel fine wire die drawing process and a wire drawing machine. Background Art

[0002] Stainless steel drawing is a common metal processing process. Its basic principle is to use a drawing machine to stretch stainless steel materials into the required shape and size. During the drawing process, the stainless steel material will be subjected to tensile force, resulting in plastic deformation and eventually forming the desired product.

[0003] In the prior art, after some drawing machines have produced a product with the same ring diameter, they need to manually remove the mold from the mold frame, and then install the mold of the subsequent required ring diameter in the mold frame. During this period, the entire equipment has to stop for a long time and wait for the new mold to be installed before it can be started, which is time-consuming and labor-intensive. In addition, since the end face of one end of the product is round or oval, it is not convenient to directly pass through the mold for drawing. Manual hard squeezing and pulling will cause greater friction and damage to the mold, thereby reducing the service life of the mold. For this reason, a stainless steel fine wire die-through drawing process and a wire drawing machine are proposed to improve the existing problems. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a steel wire continuous drawing and forming equipment and a production process thereof.

[0005] To achieve the above object, the present invention provides the following technical solution: a stainless steel fine wire die drawing process, comprising the following steps:

[0006] S1. Before drawing, the staff needs to install the pay-off wheel wrapped with the undrawn stainless steel wire on the pay-off shaft, and install the take-up wheel without the stainless steel wire on the take-up shaft. Then, pour the electrolyte whose main components are water and salt into the reaction tank, and fill the lubricant into the lubrication tank;

[0007] S2. Subsequently, the staff pushes the telescopic rod in the reaction tank upward, thereby driving the sealing waterproof plate upward, so that the electrolyte in the reaction tank reaches the same level as the wire hole in the reaction tank, and then waits for pulling;

[0008] S3. Then, the staff selects the mold that needs to be drawn and places the mold between the limit blocks in the slot. On the one hand, the edge of the mold fits the curved surface of the limit block to prevent the mold from shaking during drawing. On the other hand, due to the extrusion elasticity of the spring sheet itself, the spring sheet squeezes the mold into the slot, thereby achieving the purpose of fixing the mold.

[0009] S4. During drawing, the driving mechanism installed inside the pay-off machine starts, driving the pay-off shaft, the No. 1 rotating shaft and the No. 2 rotating shaft to start rotating, thereby driving the pay-off wheel, the No. 1 wheel and the No. 2 wheel to rotate, and the stainless steel wire enters the wheel groove of the No. 1 wheel and moves along the rotation direction of the wheel groove, and then enters the No. 2 wheel and also moves along the rotation direction of the wheel groove of the No. 2 wheel;

[0010] S5. Subsequently, the stainless steel wire passes through the third cross incision and the third silicone protrusion, enters the wire hole at one end of the reaction tank, and enters the reaction tank along the wire hole. When the stainless steel wire enters the reaction tank, on the one hand, the stainless steel wire contacts and immerses in the electrolyte, and reacts chemically with it, thereby achieving the purpose of burning the end of the stainless steel wire to a point. On the other hand, when the end of the stainless steel wire is burned to a point, the staff pulls out the telescopic rod in the reaction tank downward, causing the sealing and waterproof plate to move downward, thereby causing the electrolyte to drop to a level below the wire hole, preventing subsequent stainless steel wires from continuing to contact the electrolyte;

[0011] S6. Next, the sharpened stainless steel filament passes through the first cross-cut, through the first silicone protrusion, and into the waterproof hole. During this process, the stainless steel filament and the first silicone protrusion are tightly fitted together, and the first cross-cut scrapes the electrolyte remaining on the surface of the stainless steel filament back into the reaction tank, thereby preventing the electrolyte from entering the subsequent process. If a small amount of electrolyte flows into the waterproof hole, it will flow along the waterproof hole into the first return channel, and then flow back into the reaction tank through the first one-way water inlet valve in the first return channel;

[0012] S7. Next, the staff pushes the telescopic rod in the lubrication groove upward, thereby driving the sealing waterproof plate upward, so that the lubricant in the lubrication groove reaches a level with the wire hole in the lubrication groove;

[0013] S8. After that, the stainless steel filament continues to move, passes through the second cross incision, and enters the lubrication groove. When the stainless steel filament enters the lubrication groove, the surface of the stainless steel filament is evenly stained with lubricant, thereby achieving the purpose of all-round coating. Then, the stainless steel filament enters the wire hole at one end of the lubrication groove, passes through the third cross incision, and exits the processing box, thereby completing the preliminary processing of the stainless steel filament. If a small amount of lubricant flows into the waterproof hole, the lubricant will flow along the waterproof hole into the second return channel, and return to the lubrication groove through the second one-way water inlet valve in the second return channel.

[0014] S9. After leaving the processing box, the stainless steel filament passes through the wire insertion hole and enters the drawing box. The driving mechanism installed inside the main machine is started, which drives the transmission shaft to rotate, thereby driving the transmission wheel to start rotating. The stainless steel filament moves along the wheel groove on the surface of the transmission wheel. Then the stainless steel filament passes through the through groove and enters the mold. After drawing, the stainless steel filament moves along the micro groove to another transmission wheel and moves along the wheel groove on the surface of the transmission wheel. During this process, the supply pump is started. On the one hand, the lubricant flows into the connecting pipe along the three-way pipe through the main nozzle column, and flows into the channel and the card slot through the discharge hole, thereby completing the lubrication and cooling of the mold and the stainless steel filament; on the other hand, the lubricant flows into the long pipe along the two-way pipe through the secondary nozzle column, and lubricates and cools the transmission wheel through the spray hole;

[0015] S10. On the other hand, after the drawn stainless steel wire passes through the outlet tube and leaves the drawing box, the reel, the first rotating shaft, the second rotating shaft and the third rotating shaft start to rotate, thereby driving the reel, the first wheel, the second wheel and the third wheel to rotate, and the stainless steel wire moves along the rotation direction of the first wheel, and after passing through the second wheel and the third wheel, the stainless steel wire is wound onto the reel, thereby completing the reeling after drawing.

Then the stainless steel filament passes through the groove and enters the mold. After drawing, the stainless steel filament moves along the micro groove to another transmission wheel and moves along the wheel groove on the surface of the transmission wheel.

DETAILED DESCRIPTION

[0045] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] See also Figures 1-9 , the present invention provides the following technical solutions:

[0047] Example 1

[0048] A stainless steel fine wire die drawing process comprises the following steps:

[0049] Step 1: Before drawing, the staff needs to install the pay-off wheel 103 wrapped with the undrawn stainless steel wire on the pay-off shaft 102, and install the take-up wheel 2032 not wrapped with the stainless steel wire on the take-up shaft 2031, and then pour the electrolyte whose main components are water and salt into the reaction tank 2054, fill the lubricant into the lubrication tank 2055, and put the electrolyte and lubricant into the appropriate dosage.

[0050] Step 2. Subsequently, the staff pushes the telescopic rod 2057 in the reaction tank 2054 upward, thereby driving the sealing waterproof plate 2059 to move upward, so that the electrolyte in the reaction tank 2054 reaches a state flush with the wire hole 20510 in the reaction tank 2054. Due to the provision of the first silicone protrusion 20516 and the third silicone protrusion 20520, the electrolyte will not easily flow out of the reaction tank 2054, and then wait for pulling.

[0051] Step 3. Then, the staff selects the mold that needs to be drawn and places the mold between the limit block 3015 and the limit block 3015 in the slot 3014. On the one hand, the edge of the mold is fit with the curved surface 3016 of the limit block 3015 to prevent the mold from shaking when drawing. On the other hand, due to the extrusion elasticity of the spring sheet 30110 itself, the spring sheet 30110 squeezes the mold into the slot 3014, thereby achieving the purpose of fixing the mold.

[0052] Step 4. During pulling, the driving mechanism installed inside the pay-off machine 101 starts, driving the pay-off shaft 102, the No. 1 rotating shaft 1041 and the No. 2 rotating shaft 1043 to start rotating, thereby driving the pay-off wheel 103, the No. 1 wheel 1042 and the No. 2 wheel 1044 to rotate, and the stainless steel wire enters the wheel groove of the No. 1 wheel 1042 and moves along the rotation direction of the wheel groove, and then enters the No. 2 wheel 1044 and also moves along the rotation direction of the wheel groove of the No. 2 wheel 1044.

[0053] Step 5. Subsequently, the stainless steel filament passes through the third silicone protrusion 20520 through the third cross cut 20521, enters the wire hole 20510 at one end of the reaction tank 2054, and enters the reaction tank 2054 along the wire hole 20510. When the stainless steel filament enters the reaction tank 2054, on the one hand, the stainless steel filament contacts and immerses in the electrolyte, and reacts chemically with it, thereby achieving the purpose of burning the end of the stainless steel filament to a point. On the other hand, when the end of the stainless steel filament is burned to a point, the staff pulls out the telescopic rod 2057 in the reaction tank 2054 downward, so that the sealing waterproof plate 2059 moves downward, thereby causing the electrolyte to drop to a horizontal position below the wire hole 20510, preventing subsequent stainless steel filaments from continuing to contact the electrolyte.

[0054] Step 6. Next, the pointed stainless steel wire passes through the first cross cut 20517 and the first silicone protrusion 20516 and enters the waterproof hole 20511. During this process, the stainless steel wire fits tightly against the first silicone protrusion 20516, and the first cross cut 20517 will scrape the electrolyte remaining on the surface of the stainless steel wire back into the reaction tank 2054, thereby preventing the electrolyte from entering the subsequent process; if a small amount of electrolyte flows into the waterproof hole 20511, the electrolyte will flow into the first return channel 20512 along the waterproof hole 20511, and flow back to the reaction tank 2054 from the first one-way water inlet valve 20514 in the first return channel 20512.

[0055] Step 7. Next, the staff pushes the telescopic rod 2057 in the lubrication groove 2055 upward, thereby driving the sealing waterproof plate 2059 to move upward, so that the lubricant in the lubrication groove 2055 reaches a state flush with the wire hole 20510 in the lubrication groove 2055. Due to the provision of the second silicone protrusion 20518 and the third silicone protrusion 20520, the lubricant will not easily flow out of the lubrication groove 2055.

[0056] Step 8. After that, the stainless steel filament continues to move, passes through the second cross cut 20519 and the second silicone protrusion 20518 into the lubrication groove 2055. When the stainless steel filament enters the lubrication groove 2055, the surface of the stainless steel filament is evenly covered with lubricant, thereby achieving the purpose of all-round coating. Then the stainless steel filament enters the wire hole 20510 at one end of the lubrication groove 2055, passes through the third cross cut 20521 and the third silicone protrusion 20520 to leave the processing box 2052, thereby completing the preliminary processing of the stainless steel filament; if a small amount of lubricant flows into the waterproof hole 20511, the lubricant will flow into the second return channel 20513 along the waterproof hole 20511, and return to the lubrication groove 2055 from the second one-way water inlet valve 20515 in the second return channel 20513.

[0057] Step 9. After leaving the processing box 2052, the stainless steel filament passes through the wire insertion hole 2045 and enters the drawing box 204. The driving mechanism installed inside the main unit 201 is started, which drives the transmission shaft 3021 to rotate, thereby driving the transmission wheel 302 to start rotating. The stainless steel filament moves along the wheel groove 3023 on the surface of the transmission wheel 302, and then the stainless steel filament passes through the through groove 3013 and enters the mold. After being drawn, the stainless steel filament moves along the micro groove 3017 to another transmission wheel 302, and along the wheel groove on the surface of the transmission wheel 302. 3023 moves, and during this process, the supply pump 206 is started. On the one hand, the lubricant is flowed into the connecting pipe 3037 along the three-way pipe 3034 through the main nozzle column 3031, and flows into the channel 3012 and the card slot 3014 through the discharge hole 3019, thereby completing the lubrication and cooling of the mold and the stainless steel filament; on the other hand, the lubricant is flowed into the long pipe 3039 along the two-way pipe 3038 through the secondary nozzle column 3032, and lubricated and cooled the transmission wheel 302 through the nozzle hole 30310, thereby improving the service life of the transmission wheel 302.

[0058] Step 10. On the other hand, after the drawn stainless steel filament passes through the outlet tube 2048 and leaves the drawing box 204, the winding shaft 2031, the first rotating shaft 2033, the second rotating shaft 2035 and the third rotating shaft 2037 start to rotate, thereby driving the winding wheel 2032, the first wheel 2034, the second wheel 2036 and the third wheel 2038 to rotate, and the stainless steel filament moves along the rotation direction of the first wheel 2034, and after passing through the second wheel 2036 and the third wheel 2038, the stainless steel filament is wound onto the winding wheel 2032, thereby completing the winding after drawing.

[0075] Among them, the staff holds the handle 2058 and pushes the telescopic rod 2057 in the reaction tank 2054 upward, thereby driving the sealing waterproof plate 2059 to move upward, so that the sealing waterproof plate 2059 gradually rises in the reaction tank 2054, and then drives the liquid level in the reaction tank 2054 to rise; the staff holds the handle 2058 and pushes the telescopic rod 2057 in the lubrication tank 2055 upward, thereby driving the sealing waterproof plate 2059 to move upward, so that the sealing waterproof plate 2059 gradually rises in the lubrication tank 2055, and then drives the liquid level in the lubrication tank 2055 to rise; both the reaction tank 2054 and the lubrication tank 2055 can be adjusted according to needs.

A second one-way water inlet valve 20515 is provided at the connection between the second return channel 20513 and the lubrication groove 2055.

[0077] Among them, the stainless steel wire enters the wire hole 20510 at one end of the reaction tank 2054, and enters the reaction tank 2054 along the wire hole 20510. When the stainless steel wire enters the reaction tank 2054, on the one hand, the stainless steel wire contacts and immerses in the electrolyte, and reacts chemically with it, thereby achieving the purpose of burning the end of the stainless steel wire. On the other hand, when the end of the stainless steel wire is burned, the staff pulls out the telescopic rod 2057 in the reaction tank 2054 downward, so that the sealing waterproof plate 2059 moves downward, thereby causing the electrolyte to drop to a horizontal position below the wire hole 20510, preventing subsequent stainless steel wires from continuing to contact the electrolyte.

[0078] The sharpened stainless steel wire enters the waterproof hole 20511. If a small amount of electrolyte flows into the waterproof hole 20511, the electrolyte will flow into the first return channel 20512 along the waterproof hole 20511, and flow back to the reaction tank 2054 from the first one-way water inlet valve 20514 in the first return channel 20512.

[0079] The staff pushes the telescopic rod 2057 in the lubrication groove 2055 upward, thereby driving the sealing waterproof plate 2059 to move upward, so that the lubricant in the lubrication groove 2055 reaches a state flush with the wire hole 20510 in the lubrication groove 2055; when the stainless steel filament enters the lubrication groove 2055, the surface of the stainless steel filament is evenly covered with lubricant, thereby achieving the purpose of all-round coating, thereby completing the preliminary treatment of the stainless steel filament.

[0080] See Figure 3-Figure 4 Furthermore, a first silicone protrusion 20516 is provided at one end of the waterproof hole 20511 near the reaction groove 2054, and a first cross cut 20517 is provided on the raised side wall of the first silicone protrusion 20516.

[0081] Among them, through the cooperation of the first silicone protrusion 20516 and the third silicone protrusion 20520, the electrolyte will not easily flow out of the reaction tank 2054; through the design of the second silicone protrusion 20518 and the third silicone protrusion 20520, the lubricant will not easily flow out of the lubrication groove 2055.

[0082] The burnt-pointed stainless steel filament passes through the first cross cut 20517 and the first silicone protrusion 20516 and enters the waterproof hole 20511. During this process, the stainless steel filament fits tightly against the first silicone protrusion 20516. The first cross cut 20517 will scrape the electrolyte remaining on the surface of the stainless steel filament back into the reaction tank 2054, thereby preventing the electrolyte from entering the subsequent process.

On the other hand, after the end of the stainless steel wire is burned to a point, the staff pulls out the telescopic rod (2057) in the reaction tank (2054) downward, so that the sealing waterproof plate (2059) moves downward, thereby causing the electrolyte to drop to a horizontal position below the wire hole (20510), preventing subsequent stainless steel wires from continuing to contact the electrolyte. S6. Next, the sharpened stainless steel wire passes through the first cross cut (20517) and the first silicone protrusion (20516) and enters the waterproof hole (20511). During this process, the stainless steel wire and the first silicone protrusion (20516) are tightly fitted, and the first cross cut (20517) scrapes the electrolyte remaining on the surface of the stainless steel wire back into the reaction tank (2054), thereby preventing the electrolyte from entering the subsequent process; if a small amount of electrolyte flows into the waterproof hole (20511), the electrolyte will flow along the waterproof hole (20511) into the first return channel (20512), and return to the reaction tank (2054) from the first one-way water inlet valve (20514) in the first return channel (20512); S7. Next, the staff member pushes the telescopic rod (2057) in the lubrication groove (2055) upward, thereby driving the sealing waterproof plate (2059) to move upward, so that the lubricant in the lubrication groove (2055) reaches a state flush with the wire hole (20510) in the lubrication groove (2055); S8. Afterwards, the stainless steel filament continues to move, passes through the second cross cut (20519), through the second silicone protrusion (20518), and enters the lubrication groove (2055). When the stainless steel filament enters the lubrication groove (2055), the surface of the stainless steel filament is evenly stained with lubricant, thereby achieving the purpose of all-round coating. Then, the stainless steel filament enters the wire hole (20510) at one end of the lubrication groove (2055), passes through the third cross cut (20521), through the third silicone protrusion (20520), and leaves the processing box (2052), thereby completing the preliminary processing of the stainless steel filament; if a small amount of lubricant flows into the waterproof hole (20511), the lubricant will flow along the waterproof hole (20511) into the second return channel (20513), and return to the lubrication groove (2055) from the second one-way water inlet valve (20515) in the second return channel (20513); S9. After leaving the processing box (2052), the stainless steel filament passes through the wire insertion hole (2045) and enters the drawing box (204). The driving mechanism installed inside the main machine (201) starts, and on the one hand, it drives the transmission shaft (3021) to rotate, thereby driving the transmission wheel (302) to start rotating. The stainless steel filament moves along the wheel groove (3023) on the surface of the transmission wheel (302). Then, the stainless steel filament passes through the through groove (3013) and enters the mold. After being drawn, the stainless steel filament moves along the micro groove (3017) to another transmission wheel (302), and along the transmission wheel (302 ) moves along the wheel groove (3023) on the surface. During this process, the supply pump (206) is started. On the one hand, the lubricant flows into the connecting pipe (3037) along the three-way pipe (3034) through the main nozzle column (3031), and flows into the channel (3012) and the card groove (3014) through the discharge hole (3019), thereby completing the lubrication and cooling of the mold and the stainless steel filament; on the other hand, the lubricant flows into the long pipe (3039) along the two-way pipe (3038) through the secondary nozzle column (3032), and lubricates and cools the transmission wheel (302) through the nozzle hole (30310); S10. On the other hand, after the drawn stainless steel filament passes through the outlet tube (2048) and leaves the drawing box (204), the reel (2031), the first rotating shaft (2033), the second rotating shaft (2035) and the third rotating shaft (2037) start to rotate, thereby driving the reel (2032), the first wheel (2034), the second wheel (2036) and the third wheel (2038) to rotate, and the stainless steel filament moves along the rotation direction of the first wheel (2034), and after passing through the second wheel (2036) and the third wheel (2038), the stainless steel filament is wound onto the reel (2032), thereby completing the reeling after drawing.
