Description
Technical Field
[0001] The utility model relates to the technical field of improving the surface quality of dry-drawn steel wires, and more specifically, to an anti-shake rotary pressure roller for steel wire drawing. Background Art
[0002] Wire drawing is a metal plastic processing process in which a wire rod or wire blank is pulled out from the die hole of a wire drawing die under the action of a drawing force to produce a small-section steel wire or non-ferrous metal wire. Wires of different cross-sectional shapes and sizes made of various metals and alloys can be produced by drawing.
[0003] During the drawing process, the steel wire will produce intermittent bright spots due to shaking, which affects the surface quality of the steel wire. The existing tooling uses wool felt to press the steel wire to prevent the steel wire from shaking, but the wool felt can be easily cut by the high-speed running steel wire, thus losing its function. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model aims to provide a vibration-proof rotary pressure roller for wire drawing.
[0005] To achieve the above objectives, the utility model provides the following technical solutions: a wire drawing anti-shake rotating pressure roller, comprising a main body component and an anti-shake component and a support component installed on the top of the main body component, wherein the anti-shake component is located above the support component.
[0006] Among them, the main body component includes a base and a column inserted into the base, a first spring is installed between the outer wall of the column and the inner wall of the base, a connecting rod is horizontally passed through the outer wall of the column, a fixing plate is installed on the top of one end of the connecting rod, and a bracket is installed on the top of the fixing plate.
[0007] The anti-shake component includes a bearing seat, which is connected to the side wall of the bracket. A pressure roller is connected to the inside of the bearing seat, and the pressure roller is located above the supporting component. The top of the fixed plate is slidably connected to an adjustment component, the supporting component is passed through the inside of the adjustment component, and the adjustment component is located below the pressure roller.
[0008] The utility model is further configured as follows: the anti-shake component also includes a groove opened on the outer wall of the pressure roller and a pulley sleeved on the outer wall of the pressure roller, the inner wall of the pulley is connected to a slider, and the slider is slidably connected to the inside of the groove.
[0009] By adopting the above technical solution, a high-speed rotating pressure roller is added to the outlet of the steel wire drawing die. When the steel wire shakes during transportation, the pressure roller moves up and down under the influence of the shaking of the steel wire and the tension force, and the column, connecting rod, fixed plate and bracket move up and down synchronously, causing the column to slide up and down inside the base to pull the first spring. The reaction force of the first spring reversely offsets the shaking and tension force of the steel wire, so that the anti-shake component is always in contact with the outer surface of the steel wire, thereby achieving the purpose of preventing the shaking of the steel wire.
[0010] The utility model is further configured as follows: the adjustment assembly includes a slide table slidably connected to the top of the fixed plate and a vertical plate connected to the top of the slide table, the support assembly is located on one side of the vertical plate, and two cylinders are installed on the other side of the vertical plate, and the spacing between the two cylinder piston rods is the same as the length of the pulley.
[0011] The utility model is further configured as follows: the support assembly includes a fixed seat installed on the side wall of the connecting rod and a connecting plate connected to the side of the fixed seat away from the main body assembly, the side wall of the connecting plate is connected to a guide rod, one end of the guide rod away from the connecting plate is passed through the interior of the adjustment assembly, and the axis of the guide rod is arranged parallel to the axis of the pressure roller.
[0012] The utility model is further configured as follows: a guide seat is installed on one side of the vertical plate close to the guide rod, the end of the guide rod is inserted into the interior of the guide seat, two sets of guide rails are installed on the top of the fixed plate, and the slide is slidably connected above the two sets of guide rails.
[0013] The utility model is further configured as follows: a second spring is connected between the guide seat and the connecting plate, and the second spring is sleeved on the outer side wall of the guide rod.
[0014] By adopting the above technical solution, if the steel wire is offset, the pulley will slide on the outer wall of the pressure roller under the influence of the lateral offset force of the steel wire. At the same time, the pulley squeezes the piston rod of the cylinder, causing the cylinder to drive the vertical plate, the slide and the guide seat to move synchronously. The pulley remains in contact with the steel wire. During the sliding process of the guide seat following the slide, the guide rod slides inside the corresponding through hole, and the second spring is squeezed or pulled and deformed by the force. At the same time, the reaction force of the second spring is transmitted in the opposite direction and conflicts with the lateral offset force of the steel wire. The second spring has a buffering effect on the lateral offset force of the steel wire, which not only ensures that the pulley remains in contact with the steel wire and eliminates the high-frequency jitter of the steel wire, thereby avoiding intermittent bright spots caused by jitter during the pulling process, but also the pulley can be used to pull the steel wire back to the normal conveying direction, so that the steel wire can perform normal anti-shake operation.
[0015] In summary, the present application includes at least one of the following beneficial technical effects:
[0016] (1) A high-speed rotating pressure roller is added at the outlet of the wire drawing die. The pressure roller moves up and down under the influence of the vibration and tension of the wire, causing the column to slide up and down inside the base to pull the first spring. The reaction force of the first spring counteracts the vibration and tension of the wire. The pressure roller lightly presses the wire at the die outlet, and the wire drives the pressure roller to rotate at high speed to prevent the wire from vibrating, eliminate bamboo wire, and eliminate high-frequency vibration of the wire.
[0017] (2) By setting a pulley, when the steel wire is conveyed through the pulley, if the steel wire is offset, the pulley will squeeze the piston rod of the cylinder laterally, and the cylinder will drive the vertical plate, slide and guide seat to move synchronously. The second spring will buffer the lateral offset force of the steel wire, which not only ensures that the pulley and the steel wire maintain contact, but also eliminates the high-frequency jitter of the steel wire, thereby avoiding intermittent bright spots caused by jitter during the pulling process.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0029] See also Figure 1-5 , the utility model provides the following technical solutions:
[0030] For example, see Figure 1 , a wire drawing anti-shake rotary pressure roller, including a main body component 1, an anti-shake component 2 is installed on the top of the main body component 1, the main body component 1 is used to support the anti-shake component 2, and the anti-shake component 2 is used to press the conveyed steel wire, that is, when the steel wire passes the position of the anti-shake component 2, the anti-shake component 2 is pressed on the outside of the steel wire, and the steel wire drives the anti-shake component 2 to rotate highly, and at the same time, the anti-shake component 2 moves up and down under the influence of the tension of the steel wire, and the anti-shake component 2 applies the up and down movement force to the main body component 1, the main body component 1 and the anti-shake component 2 cooperate to achieve the purpose of preventing the steel wire from shaking, and eliminate the bamboo wire, the specific structure of the main body component 1 is as follows:
[0031] See also Figure 1 and Figure 4 The main component 1 includes a base 11 and a column 12 inserted into the base 11. The outer wall of the column 12 is horizontally penetrated with a connecting rod 13. A fixing plate 15 is installed on the top of one end of the connecting rod 13. A bracket 14 is installed on the top of the fixing plate 15. The base 11, the column 12 and the connecting rod 13 are used to support the fixing plate 15 and the bracket 14. The bracket 14 and the fixing plate 15 cooperate to support the anti-shake component 2, so that the anti-shake component 2 is in a suspended state, which is convenient for the steel wire to be moved from the anti-shake component 2. A first spring 16 is installed between the outer wall of the column 12 and the inner wall of the base 11, and when the anti-shake component 2 moves up and down due to the vibration and tension force, the column 12, the connecting rod 13, the fixing plate 15 and the bracket 14 move up and down synchronously, causing the column 12 to slide up and down inside the base 11 to pull the first spring 16. The reaction force of the first spring 16 reversely offsets the vibration and tension force of the steel wire, so that the anti-shake component 2 is always in contact with the outer surface of the steel wire, thereby achieving the purpose of preventing the steel wire from shaking.
[0032] See also Figure 1 and Figure 2 The specific structure and usage of the anti-shake component 2 are as follows:
[0033] The anti-shake assembly 2 includes a bearing seat 21, which is connected to the side wall of the bracket 14. A pressure roller 22 is connected to the inside of the bearing seat 21. The bearing seat 21 is used to support the pressure roller 22, so that the pressure roller 22 is always in a horizontal state. The pressure roller 22 is used to contact the steel wire, and the pressure roller 22 can rotate synchronously with the transportation of the steel wire. A pulley 24 is sleeved on the outer wall of the pressure roller 22. Since the pressure roller 22 is long and no blocking and limiting mechanism is set at the end, in order to prevent the steel wire from being separated from the pressure roller 22 during transportation, the steel wire can be transported through the pulley 24, that is, the staff can make the steel wire on the outer wall or the outer wall of the pressure roller 22 according to needs. The belt pulley 24 is conveyed by the outer wall of the belt pulley 24, and both the belt pulley 24 and the pressure roller 22 can achieve the purpose of preventing the steel wire from shaking. In order to prevent the belt pulley 24 from being unable to rotate synchronously when the pressure roller 22 rotates, a groove 23 is opened on the outer wall of the pressure roller 22, and a slider is connected to the inner wall of the belt pulley 24, and the slider is slidably connected to the inside of the groove 23. Through this arrangement, the belt pulley 24 can only slide and adjust its position along the axial extension direction of the pressure roller 22, so as to adapt to the deviation of the steel wire during the conveying process. The belt pulley 24 is limited in the axial direction by the groove 23 and the slider, so that the belt pulley 24 can rotate synchronously with the pressure roller 22.
[0034] See also Figure 1-Figure 3 The top of the fixed plate 15 is slidably connected with an adjustment component 4, which is located below the pressure roller 22. The adjustment component 4 is used to limit the pulley 24 on the outer wall of the pressure roller 22, and the position of the pulley 24 sliding on the outer wall of the pressure roller 22 can be adjusted by the adjustment component 4. The specific structure and adjustment method of the adjustment component 4 are as follows:
[0035] See also Figure 1 and Figure 3 The adjustment assembly 4 includes a slide 42 slidably connected to the top of the fixed plate 15. Two sets of guide rails 41 are installed on the top of the fixed plate 15. The slide 42 is slidably connected above the two sets of guide rails 41. The slide 42 slides between the fixed plate 15 and the pressure roller 22 using the two sets of guide rails 41, and the sliding direction of the slide 42 is the same as the extension direction of the pressure roller 22. A vertical plate 43 is connected to the top of the slide 42. Two cylinders 44 are installed on one side of the vertical plate 43. The spacing between the piston rods of the two cylinders 44 is the same as the length of the pulley 24. When the slide 42 slides along the extension direction of the guide rails 41, the slide 42 is moved. The vertical plate 43 and the two cylinders 44 are driven to move synchronously, and the piston rods of the two cylinders 44 are in an extended state, that is, they extend to the two ends of the pulley 24 respectively. The pulley 24 is limited by the cooperation of the two cylinders 44. When the steel wire is conveyed through the pulley 24, if the steel wire is offset, the pulley 24 slides on the outer wall of the pressure roller 22 under the influence of the lateral offset force of the steel wire. At the same time, the pulley 24 squeezes the piston rod of the cylinder 44, causing the cylinder 44 to drive the vertical plate 43 and the slide 42 to move synchronously. This arrangement can keep the pulley 24 in contact with the steel wire.
[0036] See also Figure 1 The top of the fixed plate 15 is provided with a support assembly 3, the pressure roller 22 is located above the support assembly 3, the support assembly 3 is located on the side of the vertical plate 43 away from the cylinder 44, the side of the vertical plate 43 close to the support assembly 3 is provided with a guide seat 45, the support assembly 3 is penetrated inside the guide seat 45, the guide seat 45 is synchronously displaced while the slide 42 slides on the guide rail 41, so that the guide seat 45 slides on the support assembly 3, the support assembly 3 and the guide rail 41 can both guide the adjustment assembly 4, and the specific structure of the support assembly 3 is as follows:
[0037] See also Figure 1 and Figure 5 The support assembly 3 includes a fixed seat 31 installed on the side wall of the connecting rod 13 and a connecting plate 32 connected to the fixed seat 31 on the side away from the main assembly 1. The side wall of the connecting plate 32 is connected to a guide rod 34. The fixed seat 31 and the connecting plate 32 cooperate so that the axis of the guide rod 34 is parallel to the axis of the pressure roller 22, and the end of the guide rod 34 away from the connecting plate 32 is penetrated into the interior of the guide seat 45, that is, a through hole with the same diameter as the guide rod 34 is opened on the guide seat 45. When the guide seat 45 slides following the slide 42, the guide rod 34 slides inside the corresponding through hole, so that the guide rod 34 guides the guide seat 45.
[0038] In this embodiment, specifically: Figure 5 A second spring 33 is connected between the guide seat 45 and the connecting plate 32. The second spring 33 is sleeved on the outer wall of the guide rod 34. The steel wire is deviated during transportation in the pulley 24. The adjustment component 4 slides as a whole following the deviation of the pulley 24. During the sliding process of the guide seat 45 on the outer wall of the guide rod 34, the second spring 33 is squeezed or pulled and deformed. At the same time, the reaction force of the second spring 33 is transmitted in the reverse direction and conflicts with the lateral deviation force of the steel wire. The second spring 33 has a buffering effect on the lateral deviation force of the steel wire, which not only ensures that the pulley 24 maintains contact with the steel wire, but also uses the pulley 24 to pull the steel wire back to the normal conveying direction.
[0039] Specifically, the staff installs the rotating pressure roller 22 at the die mouth of the steel wire drawing. The steel wire will produce intermittent bright spots due to the shaking during the drawing process, which affects the surface quality of the steel wire. The previous tooling used wool felt to press the steel wire, but the wool felt can be easily cut off by the high-speed running steel wire and lose its function. In order to eliminate the shaking of the steel wire, the steel wire in the drawing process is fitted with the outer wall of the pressure roller 22, and the steel wire drives the pressure roller 22 to rotate synchronously during the transmission process. This setting can avoid the situation where the wool felt is easily cut off and loses its function by the high-speed running steel wire. When the steel wire shakes during the transportation process, the pressure roller 22 moves up and down under the influence of the shaking of the steel wire and the tension force, and the column 12, the connecting rod 13, the fixed plate 15 and the bracket 14 move up and down synchronously, causing the column 12 to slide up and down inside the base 11 to pull the first spring 16, and the reaction force of the first spring 16 reversely offsets the shaking and tension force of the steel wire, so that the anti-shake component 2 is always in contact with the outer surface of the steel wire, thereby achieving the purpose of preventing the steel wire from shaking.
[0040] When the steel wire is lightly pressed by the pressure roller 22 for anti-shake, the steel wire will also experience lateral displacement force. Since the pressure roller 22 is relatively long and no blocking and limiting mechanism is set at the end, in order to prevent the steel wire from being separated from the pressure roller 22 during transportation, the steel wire can be transported by the pulley 24. The staff can select the pressure roller 22 and the pulley 24 for anti-shake transportation as needed. Both transportation using the pulley 24 and transportation using the pressure roller 22 can achieve the purpose of preventing the steel wire from shaking.
[0041] When the steel wire is conveyed through the pulley 24, if the steel wire is offset, the pulley 24 slides on the outer wall of the pressure roller 22 under the influence of the lateral offset force of the steel wire. At the same time, the pulley 24 squeezes the piston rod of the cylinder 44, causing the cylinder 44 to drive the vertical plate 43, the slide 42 and the guide seat 45 to move synchronously. The pulley 24 maintains contact with the steel wire. During the sliding of the guide seat 45 following the slide 42, the guide rod 34 slides inside the corresponding through hole, and the second spring 33 is squeezed or pulled and deformed by the force. At the same time, the reaction force of the second spring 33 is transmitted in the reverse direction and conflicts with the lateral offset force of the steel wire. The second spring 33 has a buffering effect on the lateral offset force of the steel wire, which not only ensures that the pulley 24 maintains contact with the steel wire and eliminates the high-frequency jitter of the steel wire, thereby avoiding intermittent bright spots caused by jitter during the drawing process, but also uses the pulley 24 to pull the steel wire back to the normal conveying direction.
[0042] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
