Description

Technical Field

[0001] The invention belongs to the technical field of metallurgical equipment, and particularly relates to an aluminum alloy wire rolling machine and an operating method thereof. Background Art

[0002] Rolling is a metalworking process that refers to a pressure processing method in which a metal billet is passed through the gap between a pair of rotating rollers, where the compression of the rollers reduces the cross-section of the material and increases its length.

[0003] Chinese patent application number CN201510504808.8 discloses a continuous casting and rolling system for aluminum alloy wires, which includes a tundish for transferring aluminum alloy melt, a crystallizer connected below the tundish, and a twin-roll caster below the crystallizer. The continuous casting and rolling system for aluminum alloy wires also includes a seeding mechanism located below the twin-roll caster. Before casting begins, the seeding mechanism sends a seeding head into the crystallizer through the twin-roll caster. After the aluminum alloy melt is poured into the tundish and cooled by the crystallizer, a solidified shell is formed above the seeding head. The solidified shell enters the casting rolls of the twin-roll caster under the pulling action of the seeding mechanism, and is formed into the desired shape after cooling and rolling by the rolls.

[0039] Example 1

[0040] like Figure 1 As shown, the present invention provides an aluminum alloy wire rolling mill, comprising a melting tank 1, a crystallizer 2 arranged below the melting tank 1, and a seeding rod 3 arranged below the crystallizer 2, wherein the seeding rod 3 is located directly above the middle position of the rolling mechanism, and the rolling mechanism is composed of two integrated rolling assemblies 4 symmetrically mounted on a vertical plate, and a comprehensive winding assembly 7 is located outside one side of the rolling mechanism and mounted on the vertical plate.

[0041] Please focus on Figure 2The integrated rolling assembly 4 includes a front plate 404 and a rear plate 403. The two ends of the rolling roller 402 are movably mounted on the front plate 404 and the rear plate 403 respectively through bearings, and the rolling rollers 402 of different models are evenly distributed between the front plate 404 and the rear plate 403 around the axis of the front plate 404. At the same time, a micro motor 2 is installed on each rolling roller 402, and the micro motor 2 is used to drive the rolling roller 402 to rotate and roll; the rotating shaft connects the front plate 404 and the rear plate 403, and the rotating shaft is located at the front plate 404 and the rear plate 403. In the middle position of the plate 404, the outer fixed shell 401 is sleeved on the outside of the front plate 404 and the rear plate 403. At the same time, both ends of the rotating shaft are movably mounted on the outer fixed shell 401 through bearings, and one end of the rotating shaft passes through the outer fixed shell 401 and is mounted with gear 2 409. Gear 1 408 is mounted on motor 1 406, and gear 1 408 is engaged with gear 2 409. Motor 1 406 is mounted on the outer fixed shell 401 through a motor fixing base 407, and the outer fixed shell 401 is mounted on the vertical plate.

[0042] When it is necessary to switch to rolling different types of wires, motor 1 406 is turned on. Motor 1 406 drives the front plate 404 and the rear plate 403 to rotate, so that the rolling roller 402 corresponding to the specified model is stopped directly under the seeding rod 3, so that different types of aluminum alloy wires can be produced; wherein the motor 1 406 is a servo motor, so that the accuracy of the rotation stop position can be ensured.

[0043] The design of the comprehensive rolling assembly 4 enables the device to roll aluminum alloy wires of different models and cross-sections, and has wide applicability.

[0044] Please focus on Figure 3 and Figure 4 The comprehensive winding assembly 7 includes a fixed plate 707 installed on the vertical plate, a motor 2 702 installed on the fixed plate 707, a rotating disk 701 installed on the motor 2 702 through an axis 705, and a winding roller 703 movably installed on the rotating disk 701. The winding rollers 703 suitable for different types of wires are evenly distributed on the rotating disk 701 around the axis of the rotating disk 701. A micro motor 1 704 is installed at one end of the winding roller 703, and the micro motor 1 704 is used to drive the winding roller 703 to rotate and wind; a limiting device 706 is installed in the middle position of the rotating disk 701, and the limiting device 706 is used to limit the wire wound on the winding roller 703 to prevent the wire from falling off the winding roller 703.

[0045] The limiting device 706 includes a fixed shaft 7061 installed on the rotating disk 701, a sliding seat 7062 sleeved outside the fixed shaft 7061 and a cylinder 2 7063 installed on the rotating disk 701, and a limiting plate 7064 is installed on the cylinder 2 7063, and the limiting plate 7064 is installed on the sliding seat 7062.

[0046] When the second cylinder 7063 is turned on, the second cylinder 7063 drives the limiting plate 7064 to move along the length direction of the fixed shaft 7061. Therefore, the limiting device 706 can adapt to the winding roller 703 of different specifications.

[0047] At the same time, the motor 2 702 is also a servo motor. When the motor 1 406 is turned on, the motor 2 702 is turned on synchronously, and the motor 2 702 rotates the winding roller 703 corresponding to the specified model to the winding position.

[0048] The rolling mill disclosed in the first embodiment is capable of rolling and winding aluminum alloy wires of different models and cross-sections and has wide applicability.

[0049] Example 2

[0050] Please focus on Figure 2 The comprehensive rolling assembly 4 in the aluminum alloy wire rolling mill disclosed in the second embodiment further includes a limiting assembly 405, and other devices and their installation positions are the same as those in the first embodiment.

[0051] The limiting assembly 405 includes a cylinder 1 4052 mounted on the outer fixed housing 401 via a cylinder mounting seat. A guide shaft 4051 is mounted on the cylinder 1 4052. The guide shaft 4051 is located directly in front of a flange 2 4054. The flange 2 4054 is mounted on the outer fixed housing 401. The front plate 404 is mounted with a flange 1 4053 at a position corresponding to the flange 2 4054. At the same time, a plurality of flanges 1 4053 are evenly mounted on the front plate 404 around the axis of the front plate 404. Through holes are provided on the rear plate 403 at positions corresponding to the flanges 1 4053.

[0052] When the motor 406 is turned on and rotated to the rolling roller 402 corresponding to the specified model, the cylinder 4052 is turned on. The cylinder 4052 drives the guide shaft 4051 to pass through the flange 2 4054, the flange 1 4053 and the through hole in sequence, so that the rolling roller 402 can be firmly fixed in its position to avoid the rolling roller 402 from stopping in the wrong position. Inserting the guide shaft 4051 can eliminate looseness during rotation and enhance the load capacity of the integrated rolling assembly 4.

[0053] According to the model required by the staff, a servo motor is used to switch to the appropriate rolling roller 402. After the position of the rolling roller 402 of different models is changed, a cylinder 4052 is used to insert the guide shaft 4051 for fixing.

[0058] After the wire is discharged from the comprehensive rolling assembly 4, it passes through the bottom of roller 2 506, the top of roller 1 502, the bottom of roller 3 605 and the top of roller 4 606 in sequence, and finally reaches the comprehensive winding assembly 7 for winding. The function of the stabilizing roller assembly 1 5 and the stabilizing roller assembly 2 6 is to allow the formed wire to gradually stabilize before winding, while ensuring the tension of the wound wire.

[0059] The roller one 502, roller two 506, roller three 605 and roller four 606 are provided with different areas corresponding to different types of wires, and each area is provided with a groove that conforms to the corresponding model. Different types of wires pass through the corresponding area to facilitate subsequent winding.

[0060] Motor one 406, cylinder one 4052, motor two 702, and cylinder two 7063 are communicatively coupled to the controller.

The control system connects the various actuators, allowing them to move along logical paths. Programming controls the actuators to follow the desired steps.

[0062] Based on the above device, the third embodiment of the present invention further proposes an operating method using the above aluminum alloy wire rolling mill, comprising the following steps:

[0063] Step 1: The wire is formed by the melting tank 1, the crystallizer 2 and the seed rod 3. The wire is first rolled into shape by the comprehensive rolling assembly 4, and then passes through the stabilizing roller assembly 1 5 and the stabilizing roller assembly 2 6 in sequence, and finally coiled by the comprehensive winding assembly 7;

[0064] Step 2: When the wire type needs to be changed, the motor 1 406 is turned on to rotate the rolling roller 402 corresponding to the specified type, and then the cylinder 1 4052 is turned on. The cylinder 1 4052 drives the guide shaft 4051 to pass through the flange 2 4054, the flange 1 4053 and the through hole in sequence to fix the rolling roller 402;

[0065] Step 3: When the motor 1 406 is turned on, the motor 2 702 is turned on synchronously. The motor 2 702 rotates the winding roller 703 corresponding to the specified model to the winding position, thereby facilitating the winding of the specified model of wire;

[0066] Step 4: After the second cylinder 7063 is turned on, the second cylinder 7063 drives the limiting plate 7064 to move along the length direction of the fixed shaft 7061, so as to limit the wires wound by the winding roller 703 of different specifications.
