Description

Technical Field

[0001] The present invention belongs to the technical field of rolling, and in particular relates to a high-capacity casting and rolling device and a method of using the same. Background Art

[0002] The planetary rolling mill of the casting and rolling method is an efficient rolling method that generates deformation heat through a single large deformation to make the temperature of the ingot and the environment reach 700-800°C, thereby realizing the recrystallization of the deformation structure of the copper tube;

[0003] The conventional casting and rolling process adopts a cycle mode of: billet positioning → core rod → trolley feeding → secondary feeding → rolling → rolling end → core rod withdrawal → trolley withdrawal → billet positioning;

[0004] In the operation process of the traditional casting and rolling method, the actual rolling stage accounts for 80%-85% of the entire process, and the remaining auxiliary materials account for 15%-20%; during the auxiliary time stage, the rolling environment temperature changes from high to low, and during the rolling process, the ambient temperature changes from low to high; the fluctuation of the rolling environment temperature has an adverse effect on the product grain size, the final product quality and the equipment life;

[0005] The existing process uses a core rod. The insertion and withdrawal of the core rod in each cycle is a necessary process, and the withdrawal of the core rod in the first rolling cycle must be completed before the second rolling cycle begins. The withdrawal of the core rod is related to the length of the billet. The longer the length, the longer the withdrawal of the core rod.

[0006] In order to reduce the proportion of auxiliary time of core rod action, the industry currently generally adopts the method of increasing the length of the billet. This method reduces the proportion of core rod action time, but increases the single core rod action time;

[0007] To this end, the present invention designs a high-capacity casting and rolling device and a method of using the same, which are used to solve the technical problem that the core rod withdrawal action is related to the length of the ingot, and the longer the length, the longer the core rod withdrawal time.

The movable plate 28 are slidably connected to the guide column 29, two vertical plates 30 are fixed on one side of the movable plate 28, a pinch roller 31 is rotatably connected between the two vertical plates 30 located at the top through a bearing, and a pinch roller 31 is rotatably connected between the two vertical plates 30 located at the bottom through a bearing, a fourth motor 32 is fixed on one side of one of the vertical plates 30 located at the top, and a fourth motor 32 is also fixed on one side of one of the vertical plates 30 located at the bottom, and the output end of the fourth motor 32 passes through one of the vertical plates 30 and is fixed to the pinch roller 31. When the first core rod 3 is retracted, the third motor 26 is started, and the output end of the third motor 26 drives the first bidirectional screw rod 27 to rotate, so that the two movable plates 28 move in a direction away from each other, so that the outer sides of the two movable plates 28 are no longer in contact with the first core rod 3;

[0050] A second rough casting blank 37 is arranged on one side of the second guide groove body 6, a second core rod 38 is penetrated on the inner side of the second rough casting blank 37, and a turning mechanism is installed on one side of the second guide groove body 6, and the turning mechanism is used to turn over and load the second rough casting blank 37 and the second core rod 38;

When the first rough tube billet 4 is rolled and material preparation is required, the second core rod 38 is inserted into the second rough tube billet 37, and the second rough tube billet 37 is placed between the two extrusion plates 42, and then the sixth motor 40 is started. The output end of the sixth motor 40 drives the second bidirectional screw 41 to rotate, thereby causing the two extrusion plates 42 to move in a direction close to each other, so that the extrusion plates 42 clamp and fix the second rough tube billet 37, and the material preparation is completed;

[0052] A method for using a high-capacity casting and rolling device comprises the following steps:

[0053] S1: During processing, the first core rod 3 is inserted into the first rough casting billet 4;

[0054] S2: When the first rough tube casting billet 4 has 0.5-1m left at the rolling tail, the car body 7 is withdrawn in advance;

[0055] S3: After the rolling of the first rough casting slab 4 is completed, the clamping and conveying mechanism is started to quickly withdraw the first core rod 3 from the bottom of the vehicle body 7;

[0056] S4: After the first core rod 3 is retracted, the second rough casting 37 and the second core rod 38 are simultaneously transferred into the guide roller 25 under the action of the turning mechanism;

[0057] S5: The vehicle body 7 is fixed with the second core rod 38 by the clamping mechanism and is advanced synchronously with the vehicle body 7;

[0058] S6: Start rolling, and then cycle S1 again.

[0059] A specific application of this embodiment is: the device is electrically connected to an external power source. When the first rough tube ingot 4 needs to be rolled, the core rod piercing and traction device is first started (the core rod piercing and traction device is a commonly used device that can penetrate the core rod into the rough tube ingot. It belongs to the existing mature technology, and its electrical connection relationship and specific circuit structure are not repeated here), and one end of the first core rod 3 is inserted into the first rough tube ingot 4. Then, the other end of the first core rod 3 is placed between the two clamping plates 17, and then the rolling machine 2 and the second motor 13 are started. The output end of the second motor 13 drives the diamond plate 14 to rotate, so that the first transmission rod 15 pushes the first movable arm 16 to rotate along the pin, and the second transmission rod 18 pulls the second movable arm 20 to rotate along the pin, thereby causing the two clamping plates 17 to rotate in a direction close to each other until the first core rod 3 is clamped and fixed;

[0060] Next, the advance amount of the power member 23 is set, and then the power member 23 is started. The output end of the power member 23 drives the balance plate 24 to move. When the balance plate 24 moves to the specified position, the power member 23 is closed, and then the first motor 11 is started. The output end of the first motor 11 drives the second gear 12 to rotate, so that the second gear 12 drives the first gear 10 to rotate through the chain, and then the rotating rod 8 rotates and the walking wheel 9 rotates. Under the action of friction, the vehicle body 7 moves forward at a uniform speed along the inner side of the first guide groove 5;

[0061] When the vehicle body 7 moves toward the second guide groove body 6, the vehicle body 7 drives the first core rod 3 to push the first rough tube casting 4, so that the first rough tube casting 4 moves along the inner side of the guide roller 25 until the first rough tube casting 4 enters the rolling mill 2. When the rolling tail of the first rough tube casting 4 has 0.5-1m left, the first motor 11 is controlled to rotate in the opposite direction, so that the vehicle body 7 returns to its original position in advance. When the first rough tube casting 4 is processed and discharged from one side of the rolling mill 2, the power member 23 and the third motor 26 are started at this time. The power member 23 drives the balance plate 24 to reset, and the output end of the third motor 26 drives the first bidirectional screw rod 27 to rotate. Because the moving plate 28 is threadedly connected to the first bidirectional screw rod 27, the threads at both ends of the first bidirectional screw rod 27 rotate in opposite directions, and the moving plate 28 is slidably connected to the guide column 29, so the two moving plates 28 move in a direction close to each other until the outer sides of the two moving plates 28 are in contact with the first core rod 3.

[0062] Then, the fourth motor 32 is started to control the output ends of the two fourth motors 32 to rotate in opposite directions, and the first core rod 3 is moved from the bottom of the vehicle body 7 in a direction away from the second guide groove 6 under the action of the friction between the first core rod 3 and the movable plate 28, until it is completely separated from the second guide groove 6;

[0063] After the first core rod 3 is retracted, the third motor 26 is started, so that the movable plate 28 drives the clamping roller 31 to reset, and then the fifth motor 36 is started, and the output end of the fifth motor 36 drives the cross bar 34 and the flip plate 35 to rotate. When the flip plate 35 rotates to 180° of the second transmission rod, the fifth motor 36 is turned off, and the sixth motor 40 is started at this time, and the output end of the sixth motor 40 drives the second bidirectional screw 41 to rotate, so that the two extrusion plates 42 move in a direction away from each other, so that the extrusion plates 42 no longer clamp and fix the second rough tube billet 37, and the second rough tube billet 37 falls into the guide roller 25 with the second core rod 38. At this time, the fifth motor 36 is started again, and the fifth motor 36 is controlled to rotate in the opposite direction to reset the flip plate 35, and the sixth motor 40 is controlled to rotate in the opposite direction to make the extrusion plate 42 fix the next second rough tube billet 37 and the second core rod 38;

[0064] Finally, the car body 7 fixes the second core rod 38 through the clamping mechanism, and the first motor 11 is started to advance synchronously with the car body 7 to roll the second rough casting 37, and this reciprocating cycle is repeated.
