[0002] Wire drawing equipment, also commonly known as wire drawing machine or wire drawing machine, is a kind of mechanical equipment widely used in industrial production. It is mainly used to stretch and refine metal materials such as steel wire, aluminum wire, etc. By applying traction, the metal material passes through a series of dies or rollers, thereby undergoing plastic deformation, and the rough metal material is stretched to achieve the required diameter and surface finish. It is widely used in the metal processing industry. The existing wire drawing machines are all used to draw the steel wire through the wire drawing die by traction and winding during production, and the roller structure is a fixed structure. The tension of the steel wire during transportation due to stretching is fixed, and the dynamic tension cannot be adjusted according to different production requirements, which is easy to affect the quality of wire drawing production. The number of grooves of the conveying roller is fixed, and it cannot be adjusted according to production requirements during production. The conveying roller needs to be disassembled and replaced, which affects the efficiency of wire drawing production. In addition, due to the different sizes of steel wires produced by wire drawing production, smaller steel wires will shake when conveyed on large-size guide wheels, causing the steel wire to stretch and easily break.

DETAILED DESCRIPTION

[0036] Example 1: Please refer to Figure 1-6 , a wire drawing process based on a dynamic tension control method, characterized in that it comprises the following steps:

[0037] S1. Multiple rollers are arranged on the wire drawing equipment, and the conveying is monitored and controlled synchronously by the multiple rollers. The steel wire to be drawn is conveyed through the conveying rollers with multiple guides, and the real-time dynamic tension is numerically monitored with the tension sensor, and the tensile force on the conveyed object is adjusted according to the conveying situation on the rollers;

[0038] S2. When the steel wire is conveyed by the conveying roller, it can be known that the pressure on the roller is the same as the tension but in the opposite direction, so the pressure value on the roller can be obtained by real-time monitoring of the tension;

[0039] S3, and convert the dynamic tension value by the formula of converting pressure to tension, and convert it into tension data according to the dynamic pressure value on the roller using the formula T=Q / 2cosα to realize dynamic real-time tension monitoring, and adjust the tension on the roller according to the dynamic tension monitoring data;

[0040] S4. According to the production requirements, the conveying speed of the steel wire is accelerated or decelerated, and the conveying roller is driven to move and adjust through the adjustment structure, so as to adjust the tension value and change the pressure between the conveying roller and the steel wire, so as to realize dynamic tension control and adjustment.

[0041] A wire drawing device, comprising: an equipment base 1, a wire drawing machine 2, a pair of support frames 3, a traction winding roller 4, a pair of drive motors 5, a fixing frame 6, two pairs of dynamic adjustment roller wheel assemblies and a lubrication assembly;

[0042] The wire drawing machine 2 is installed on the right side of the wall of the equipment base 1, a pair of the support frames 3 are installed on the right side of the wire drawing machine 2, the traction and winding rollers 4 are installed on the pair of the support frames 3, a pair of the drive motors 5 are installed on the front and rear walls of the pair of the support frames 3, a pair of the drive motors 5 are connected to the traction and winding rollers 4, the fixed frame 6 is installed on the left side of the wire drawing machine 2, two pairs of the dynamically adjustable roller assemblies are installed on the fixed frame 6, and the lubrication assembly is installed in the middle of the wire drawing machine 2 and the fixed frame 6.

[0043] It should be noted that when using the wire drawing equipment, the wire drawing production raw materials are monitored and conveyed by the monitoring and conveying structure composed of the fixed frame 6 and the dynamically adjustable roller assembly installed thereon, and then guided and conveyed to the lubrication assembly through the guide wheel 29 to lubricate the wire drawing raw materials, and then pulled through the wire drawing machine 2 installed on the equipment base 1 for variable diameter wire drawing production and fixed to the traction and winding roller 4. During the wire drawing production, the driving motor 5 rotates to drive the traction and winding roller 4 connected to it to rotate on the support frame 3, so that the traction force is used to move the steel wire raw materials for wire drawing production. During the wire drawing production, the steel wire tension is monitored and controlled in real time through the dynamic adjustment roller assembly, thereby realizing wire drawing production based on dynamic tension control.

[0044] In a specific implementation, further, the two pairs of the dynamically adjustable roller assemblies each include: a first telescopic push rod 7, a first tension sensor 8, a first roller bracket 9, a first conveying roller 10, two pairs of embedding grooves 11, two pairs of adjusting rods 12, three adjusting roller walls 13, a connecting frame 14 and two pairs of second telescopic push rods 15;

[0046] It should be noted that when using the dynamic adjustment roller assembly, the wire drawing raw material bypasses the first conveying roller 10 installed on the first roller bracket 9, and the steel wire raw material is guided and conveyed by the rotation of the first conveying roller 10. While conveying, the first tension sensor 8 performs real-time data monitoring of the generated tension value. According to Newton's third law, it can be known that the pressure of the first conveying roller 10 is the same as the tension, and the actual tension is converted according to the conversion formula, and the first telescopic push rod 7 is controlled to retract and retract according to the change of dynamic tension, thereby adjusting the dynamic tension of the steel wire, thereby realizing dynamic tension control and ensuring the quality of wire drawing production. During production and transportation, the output end of the second telescopic push rod 15 installed on the first conveying roller 10 extends outward and moves outward through the adjustment rod 12 connected to it and installed in the embedded groove 11, driving the adjustment roller wall 13 located in the storage groove 16 to move to the middle of the conveying groove of the first conveying roller 10, thereby quickly adjusting the number of conveying grooves and quickly adjusting the conveying without disassembly and replacement, thereby ensuring the efficiency of wire drawing production.

[0047] In a specific implementation, further, three receiving grooves 16 are provided on the first conveying roller 10 .

[0052] It should be noted that when using the lubrication assembly, the steel wire raw material is guided by the guide wheel 29 and then passes through the lubrication sleeve 33 installed in the middle position of the lubricating tank 31. During the wire drawing production process, the switch valve 37 is opened to allow the lubricating oil in the oil storage tank 36 to be transported to the lubricating chamber 32 through the oil pipe 38, so that the lubricating cotton 34 in the lubricating chamber 32 is soaked with lubricating oil. When the steel wire is transported during production, the lubricating oil adheres to the outer surface of the raw steel wire through the lubricating hole 39 opened on the lubricating sleeve 33, thereby ensuring lubrication and cooling during the wire drawing production.

[0053] In a specific implementation, further, a plurality of lubrication holes 39 are provided on the lubrication sleeve 33 .

[0054] In a specific implementation, further, an observation window 40 is provided on the oil storage tank 36 .

[0055] Embodiment 2:

[0056] In a specific implementation, further, a wire drawing device may be equipped with a winding guide switching structure, the winding guide switching structure comprising: a guide bracket 18 and three reversing components, the guide bracket 18 is installed on the right side of the wire drawing machine 2, and the three reversing components are installed on the guide bracket 18;

[0057] The three reversing assemblies each include: a fixed block 19, a second roller bracket 20, a second conveying roller 21, a first conveying trough 22, a second conveying trough 23, a guide transposition groove 24, a pair of first mounting hinges 25, a pair of third telescopic push rods 26, a pair of second mounting hinges 27 and an adjusting guide tube 28;

[0058] The fixed block 19 is installed on the guide bracket 18, the second roller bracket 20 is installed on the fixed block 19, the second conveying roller 21 is movably installed on the second roller bracket 20, the first conveying groove 22 and the second conveying groove 23 are opened on the second conveying roller 21, the guide transposition groove 24 is obliquely opened at the middle position between the first conveying groove 22 and the second conveying groove 23, a pair of the first mounting hinges 25 are installed on the front and rear walls of the second roller bracket 20, one end of a pair of the third telescopic push rods 26 is installed on a pair of the first mounting hinges 25, a pair of the second mounting hinges 27 are installed on a pair of the output ends of the third telescopic push rods 26, and the adjusting guide tube 28 is installed on a pair of the second mounting hinges 27.

[0059] It should be noted that a winding guide switching structure can also be set on the right side of the wire drawing machine 2, and the guide bracket 18 installs and supports the entire reversing structure. After the steel wire is reduced in diameter through the wire drawing machine 2, it is conveyed through the second conveying roller 21 installed on the second roller bracket 20, and is reeled up by the traction reel 4 behind the conductor. The larger steel wire is guided and conveyed through the first conveying groove 22 with a wider spacing. In order to prevent the problem of shaking and stretching of the thin steel wire during guided conveying in the frame groove, the third telescopic push rod 26 installed on the second roller bracket 20 through the first mounting hinge 25 starts the output end for telescopic adjustment. The telescopic extension of the third telescopic push rod 26 will drive the adjustment guide tube 28 to move left and right, so that the steel wire located in the first conveying groove 22 moves from the guide transposition groove 24 set in the middle position to the second conveying groove 23 with a narrower size spacing, effectively preventing the steel wire from shaking during guided conveying, thereby ensuring the quality of wire drawing production.
