Description

Technical Field

[0001] This invention relates to the field of brass flat wire production technology, and more specifically to a universal rolling mill suitable for brass flat wire production. Background Technology

[0002] The production of brass flat wire involves processing brass billets into rectangular cross-section metal wire products through a series of rolling, drawing, and heat treatment processes.

[0003] In the brass processing, rolling rollers are used. However, current rolling rollers have simple structures and are generally set up independently, making it impossible to coordinate with the take-up reel. After rolling, the brass is usually directly wound into the take-up reel. This structure requires two motors, one for the take-up reel and one for the rolling roller, which increases the operating cost. Furthermore, after winding, there is a lack of external protection, making it easy for external dust, impurities, and rainwater to come into contact with the brass, affecting its subsequent use. In addition, brass will spring back after being flattened, and the thickness after springback will exceed the design value, further affecting its later use. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a universal rolling device suitable for the production of brass flat wire, in which the rolling roller and winding function are integrated, and the rotation of the central shaft enables both winding and rolling, thereby solving the problems mentioned in the background art.

[0005] This invention is achieved through the following technical solution: a universal rolling device suitable for the production of brass flat wire, comprising a central shaft, a housing, and a processing material. Thickened portions are protruded from the center of both sides of the housing. An installation groove extending into the thickened portion is provided at the center of the inner side of the housing. The central shaft is located at the center of the housing, with both ends installed in the installation groove. An externally sealed winding groove is formed between the outer ring of the central shaft and the inner wall of the housing. A fixing portion is thickened on the inner ring surface of the housing, and a fixing channel communicating with the winding groove is provided on the fixing portion. Multiple rolling rollers are provided in the fixing channel, forming an extrusion channel between the rolling rollers. An arc-shaped groove is recessed on the bottom surface of the fixing channel, and a cover plate is slidably installed in the arc-shaped groove. The processing material is coiled around the outside of the central shaft through the extrusion channel.

[0006] As a preferred technical solution, sealed bearings are installed in the mounting slots, and both ends of the central shaft are installed in the inner rings of the sealed bearings. A shaft hole communicating with the mounting slot is provided on the thickened part on one side. A shaft rod is installed at one end of the central shaft facing the shaft hole, and the other end of the shaft rod extends through the shaft hole to the outside.

[0007] As a preferred technical solution, a retaining ring is installed on the thickened part on the side with the shaft hole. The retaining ring is located outside the shaft and has multiple first screw holes. The exposed part of the shaft has multiple second screw holes in a ring structure. Each of the first screw holes is threaded with a screw rod. One end of each screw rod is threaded into the corresponding second screw hole, and the other end is equipped with a handle.

[0008] As a preferred technical solution, positioning grooves are provided on both sides of the arc-shaped groove, one end of the positioning groove extends into the fixed channel, the positioning groove and the cover plate are arranged in an arc-shaped structure, the degree of arc of the positioning groove and the cover plate matches the degree of arc of the outer ring of the outer shell, and the two sides of the cover plate are slidably arranged in the positioning groove.

[0009] As a preferred technical solution, the cover plate is provided with a third screw hole, the end of the arc groove facing the fixed channel is provided with a fourth screw hole, and the end away from the fixed channel is provided with a fifth screw hole. A hand-tightening bolt is threaded into the third screw hole, and one end of the hand-tightening bolt is threaded into the fifth screw hole.

[0010] As a preferred technical solution, the outer shell is circular in shape, and the bottom surface of the outer shell forms a parallel surface.

[0011] As a preferred technical solution, the end of the processed material located outside the rolling wheel is not rolled or deformed. This structure is the end, and the width of the remaining section of the processed material matches the width of the winding groove.

[0012] As a preferred technical solution, the central axis is hollow in the middle.

[0013] As a preferred technical solution, the outer end face of the hand-tightened bolt does not protrude beyond the outer ring surface of the outer casing.

[0014] As a preferred technical solution, ball bearings are embedded on both sides of the fixed channel, directly opposite the rolling wheel, and rollers are installed at both ends of the rolling wheel, with the other end of each roller installed in a ball bearing.

[0015] The beneficial effects of this invention are: 1. The exposed shaft can be connected to an external drive mechanism, which can drive the rotation of the central shaft. The processed material can pass through the rolling rollers and be pressed to the designed thickness by the rolling rollers, and then coiled on the central shaft. One drive mechanism can directly realize the winding and pressing functions, reducing costs. 2. After pressing, the excess processing material is cut off. Since the excess end is not under pressure, it can be stuck on the outside of the rolling roller. The positioning of the shaft by the screw can tighten the rolled processing material, making the central shaft unable to rotate freely. This applies continuous tension to the rolled material, effectively preventing the roll from loosening. 3. When the coiled processing material is pulled out later, it can pass through the rolling rollers again for secondary rolling, which reduces the error caused by springback and increases the rolling accuracy. 4. After pressing, the cover plate can move upward along the positioning groove, covering the outer opening of the fixed channel, thus sealing the processed material in the shell as much as possible and avoiding contamination.

[0016] 5. The parallel surfaces allow the outer casing to be placed on the ground, making placement easier. Attached Figure Description

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a universal rolling device suitable for the production of brass flat wire includes a central shaft 15, a housing 1, and a processing material 3. Thickened portions 7 protrude from the center of both sides of the housing 1. An installation groove extending into the thickened portion 7 is provided at the center of the inner side of the housing 1. The central shaft 15 is located at the center of the housing 1, with both ends of the central shaft 15 installed in the installation groove. An externally sealed winding groove is formed between the outer ring of the central shaft 15 and the inner wall of the housing 1. A fixed portion 16 is thickened on the inner ring surface of the housing 1. A fixed channel 2 communicating with the winding groove is provided on the fixed portion 16. Multiple rolling rollers 4 are provided in the fixed channel 2, forming an extrusion channel between the rolling rollers 4. An arc-shaped groove is recessed on the bottom surface of the fixed channel 2, and a cover plate 5 is slidably installed in the arc-shaped groove. The processing material 3 is coiled around the outside of the central shaft 15 through the extrusion channel.

[0023] In this embodiment, a sealed bearing 18 is installed in each mounting groove, and both ends of the central shaft 15 are installed in the inner ring of the sealed bearing 18. A shaft hole 17 communicating with the mounting groove is provided on the thickened part 7 on one side. A shaft rod 9 is installed at one end of the central shaft 15 facing the shaft hole 17, and the other end of the shaft rod 9 extends through the shaft hole 17 to the outside.

[0024] In this embodiment, a fixing ring 8 is installed on the thickened part 7 on the side with the shaft hole 17. The fixing ring 8 is located outside the shaft 9. The fixing ring 8 has multiple first screw holes. The exposed part of the shaft 9 has multiple second screw holes in a ring structure. Each of the first screw holes is threaded with a screw rod. One end of each screw rod is threaded into the corresponding second screw hole, and the other end is equipped with a handle 10.

[0025] In this embodiment, positioning grooves 14 are provided on both sides of the arc-shaped groove. One end of the positioning groove 14 extends into the fixed channel 2. The positioning groove 14 and the cover plate 5 are arranged in an arc-shaped structure. The degree of arc of the positioning groove 14 and the cover plate 5 matches the degree of arc of the outer ring of the outer shell 1. The two sides of the cover plate 5 are slidably disposed in the positioning groove 14.

[0026] In this embodiment, the cover plate 5 is provided with a third screw hole, the end of the arc groove facing the fixed channel 2 is provided with a fourth screw hole 12, and the end away from the fixed channel 2 is provided with a fifth screw hole 13. A hand-tightening bolt 6 is threadedly connected in the third screw hole, and one end of the hand-tightening bolt 6 is threadedly connected in the fifth screw hole 13.

[0027] In this embodiment, the outer shell 1 is circular in shape, and the bottom surface of the outer shell 1 forms a parallel surface 11. An operation hole (not shown) communicating with the winding groove is provided on one side of the outer shell. A sealing plate (not shown) is installed on the operation hole by a torsion spring hinge. After opening the sealing plate, the winding situation inside can be clearly seen, and the processing material can be pulled by a tool so that the processing material can be coiled on the central shaft.

[0028] In this embodiment, the end of the processed material 3 located outside the rolling roller 4 is not rolled or deformed. This structure is the end. The width of the remaining section of the processed material 3 matches the width of the winding groove, so that the rolling width can be limited to meet the rolling quality.

[0029] In this embodiment, the central shaft 15 is hollow in the middle, which reduces the amount of material used and the cost.

[0030] In this embodiment, the outer end face of the hand-tightening bolt 6 does not protrude from the outer ring surface of the outer casing 1, thus avoiding collisions caused by the outer ring protruding and increasing safety.

[0031] In this embodiment, ball bearings are embedded on both sides of the fixed channel 2, directly opposite the rolling wheel 4. Rollers are installed at both ends of the rolling wheel 4, and the other end of the rollers is installed in the ball bearings, so that the rolling wheel can only rotate around the rollers, avoiding misalignment and swaying.

[0032] Working principle: During operation, one end of the brass billet to be processed (i.e., processing material 3) is first passed through the extrusion channel formed by multiple rolling rollers 4 in the fixed channel 2 and wound around the outer ring of the central shaft 15. Subsequently, an external drive mechanism (such as a motor) is connected to the shaft 9 to drive the central shaft 15 to rotate around its own axis under the support of the sealed bearing 18.

[0033] The rotation of the central shaft 15 generates traction force, which continuously pulls the processed material 3 through the extrusion channel between the rolling rollers 4. During this process, the rolling rollers 4 apply pressure to the processed material 3, causing it to undergo plastic deformation, thereby rolling it into a flat wire of a preset thickness and width (the width of the flat wire matches the width of the take-up groove). After the flat wire is rolled, it continuously enters the take-up groove formed between the central shaft 15 and the inner wall of the outer shell 1 under the action of traction force, and tightly winds itself onto the central shaft 15 layer by layer, realizing the take-up and rolling operations.

[0034] After the winding reaches the predetermined length, the operator cuts off the processed material 3, leaving a section of the end located outside the rolling roller 4 that has not been deformed by rolling. At this time, by rotating the screw on the fixing ring 8, one end of the screw is threaded into the corresponding second screw hole on the shaft 9, thereby locking the shaft 9 and the fixing ring 8 relative to each other.

[0035] This locking structure prevents the central shaft 15 from rotating freely, applying continuous tension to the wound processing material 3, effectively preventing loosening caused by the elastic recovery of the material, and ensuring the tightness of the roll.

[0036] When the wound brass flat wire needs to be removed from the device for use, rotate the hand-tightening bolt 6 in the reverse direction to disengage it from the fifth screw hole 13. Slide the cover plate 5 along the positioning groove 14 to the bottom of the arc groove to expose the opening of the fixing channel 2. Pull the end of the processing material 3 to release it outward. During the unwinding process, the material passes through the extrusion channel of the rolling roller 4 again. If the material after the previous rolling produces thickness springback due to the release of internal stress, it can be rolled and corrected again by passing through the rolling roller 4 a second time, so that the thickness of the final output brass flat wire accurately meets the design requirements, effectively solving the problem of springback affecting dimensional accuracy after rolling.

[0037] When not in operation or when long-term storage is required, slide the cover plate 5 upward along the positioning groove 14 to the opening position of the closed fixing channel 2, and fix the cover plate 5 by the cooperation of the hand-tightening bolt 6 and the fourth screw hole 13.

[0038] At this time, the processing material 3 in the take-up groove is completely sealed inside the outer shell 1, which can effectively isolate dust, impurities and rainwater in the external environment, avoid material surface contamination or oxidation, and ensure the quality of subsequent use. In addition, the parallel surface 11 provided on the bottom surface of the outer shell 1 can make the device stable on the ground or workbench after it is detached from the drive mechanism, which is convenient for transportation and storage.

[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
