First, it adopts an open-and-close structure. When the equipment is blocked or the ingot needs to be removed from the center line, the linear drive mechanism drives the open and close end of the mounting frame to move in the direction of the conveying surface away from the straightening conveyor device, and the two notching and beveling units open in an eight-shaped shape. At this time, the notching mechanism and the beveling mechanism are away from the ingot, and the space above the conveying surface is fully opened, that is, the space above the ingot is fully opened, making room for the removal of the waste ingot, making it easier to lift and remove the waste ingot.

Third, it has a fast and accurate return function.

Description

Technical Field

[0001] The invention belongs to the technical field of nonferrous metal continuous casting, and particularly relates to a notching and beveling device for a straightening machine. Background Art

[0002] Rod casting production lines for non-ferrous metals such as copper alloys, aluminum alloys, magnesium alloys, and zinc alloys typically include a melting furnace, a temperature-equalizing device, a continuous casting machine, a bridge approach, a haul-off machine, a shear, a straightening machine, and a rolling mill, arranged in sequence along the direction of billet conveyance. Specifically, solid non-ferrous metals are melted into liquid form in the melting furnace. The liquid non-ferrous metal is then transported to the temperature-equalizing device via chutes or pipes. The liquid metal then flows through the diversion holes in the temperature-equalizing device into the continuous casting machine for casting to form billets. The billets pass through the bridge approach and enter the haul-off machine. After exiting the haul-off machine, the billets are conveyed to the shear, which shears off the poorly crystallized front section to form an ingot. The ingot then enters the straightening machine for straightening, notching, beveling, and roughening before entering the rolling mill for rolling.

[0003] The reason for notching and beveling is that during the casting process, sharp corners and flash are easily formed on the edges of the ingot. Sharp corners, in particular, can lead to faster cooling, poor crystallization, and increased hardness. To ensure ingot quality, these sharp corners and flash must be planed away. This process is accomplished using the notching and beveling device in the straightening machine.

[0004] The existing notching and beveling device of a straightening machine includes a fixed frame, a notching mechanism, and a beveling mechanism. The fixed frame is mounted on the frame of the straightening conveyor device across its width and located above the conveying surface of the straightening conveyor device. The notching mechanism and the beveling mechanism are mounted on the fixed frame and arranged sequentially along the ingot conveying direction. The notching mechanism includes a rotating base mounted on the fixed frame via a first linear motion guide structure. The rotating base is driven by a first drive mechanism to perform linear motion in an upward or downward direction toward or away from the conveying surface. The rotating base is mounted on a notching wheel located above the conveying surface, with the axial direction of the notching wheel perpendicular to the ingot conveying direction. The beveling mechanism includes a knife holder mounted on the fixed frame via a second linear motion guide structure. The knife holder is driven by a second drive mechanism to perform linear motion in an upward or downward direction toward or away from the conveying surface. The knife holder is mounted on a planer located above the conveying surface, with the blade of the planer perpendicular to the ingot conveying direction. The first and second drive mechanisms can be hydraulic cylinders, pneumatic cylinders, electric push rods, etc., with pneumatic cylinders being preferred. The ingot is conveyed via a straightening conveyor. A scoring wheel rolls along the top edge of the ingot, creating multiple cuts spaced two-by-two along its length. A planer then bevels the top edge of the ingot, allowing the cut scrap to fall naturally into segments, preventing scrap from piling up. It's important to note that the planer's feed rate matches the scoring wheel's.

[0005] The existing notching and beveling devices have the following problems in actual use:

[0006] First, during production, when the equipment experiences a rod jam, waste ingots entering the straightening machine need to be removed. Because the fixed frame is installed across the straightening conveyor frame and above the conveyor surface, removing the waste ingots is difficult. Specifically, the scoring and beveling mechanisms must first be activated, and then the waste ingots must be cut into small sections before removal. This process significantly increases processing time and reduces work efficiency.

[0007] Secondly, after the notching and planing mechanisms are opened and then reset, the first and second drive mechanisms need to be adjusted again during use to ensure that the planer blade's cutting distance is consistent with the notching wheel's cutting distance. This operation is dangerous, cumbersome, and difficult to ensure accuracy. Summary of the Invention

[0033] First, the device utilizes an open-and-close structure. If a rod jam occurs or an ingot needs to be removed from its centerline, the linear drive mechanism drives the open end of the mounting frame away from the conveyor surface of the straightening conveyor. The two notching and beveling units open in a figure-eight configuration. At this point, the notching and beveling mechanisms move away from the ingot, completely opening the space above the conveyor surface. This allows for easy removal of the scrap ingot, reducing processing time and improving efficiency.

[0034] Second, this device is flexible. The mechanism is supported by a cylinder. The cylinder model is designed according to actual conditions. During normal operation, the depth of the marks and the planing angle are consistent. When encountering abnormal conditions such as large burrs on the ingot, the thrust of the ingot on the mechanism is greater than the thrust set by the cylinder. The cylinder will retreat appropriately to avoid the ingot forcibly passing through the mechanism in abnormal conditions, causing damage to the mechanism.

[0035] Third, the device features a fast and accurate return function. After the scrap ingot is removed, the linear drive mechanism drives the opening and closing ends of the mounting frame toward the conveyor surface of the straightening conveyor. This closes the two notching and beveling units, quickly returning to their original positions to continue processing the incoming ingot. This eliminates the need to adjust the planer blade and scoring wheel feed rates, ensuring consistency and ultimately ensuring machining accuracy.

[0036] The device also has the advantages of simple operation, high efficiency, high processing precision and labor saving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1 、 2 , 3, 4 and 5, as well as examples, further illustrate the present invention.

[0045] The notching and beveling device of the straightening machine includes a notching and beveling unit 1, and two notching and beveling units 1 are provided. The two notching and beveling units 1 are respectively located on both sides of the conveying surface 3 of the straightening conveying device, and form an ingot conveying space with an opening facing upward; the notching and beveling unit 1 includes a mounting frame 104, a linear drive mechanism 101, a notching mechanism 105 and a beveling mechanism 106, and the notching mechanism 105 and the beveling mechanism 106 are installed on the mounting frame 104; the notching mechanism 105 and the beveling mechanism 106 are located obliquely above the conveying surface 3 of the straightening conveying device, and are arranged in sequence along the ingot conveying direction L; one end of the mounting frame 104 along the ingot conveying direction L is a mounting end, and the other end is an opening and closing end; the mounting end of the mounting frame 104 and the frame of the straightening conveying device are connected by a first hinge The linear drive mechanism 101 is installed on the frame of the straightening conveying device and is connected to the opening and closing end of the mounting frame 104 through a second hinge 103; the linear drive mechanism 101 drives the opening and closing end of the mounting frame 104 to move toward or away from the conveying surface 3 of the straightening conveying device; when the linear drive mechanism 101 drives the opening and closing end of the mounting frame 104 to move toward and away from the conveying surface 3 of the straightening conveying device, the two notching and beveling units 1 are opened, and the space above the conveying surface 3 is completely opened and is in the ingot taking position; when the linear drive mechanism 101 drives the opening and closing end of the mounting frame 104 to move toward and away from the conveying surface 3 of the straightening conveying device, the two notching and beveling units 1 are closed and are in the notching and beveling position.

[0046] The frame of the straightening conveyor provides mounting support for the first hinge 102 and the linear drive mechanism 101, while the mounting frame 104 provides mounting support for the scoring mechanism 105 and the beveling mechanism 106. The linear drive mechanism 101 drives the first hinge 102 and the second hinge 103 to rotate, driving the mounting frame 104 to rotate about the first hinge 102, causing the open and closed ends of the mounting frame 104 to move toward or away from the conveying surface 3 of the straightening conveyor. When the open and closed ends of the mounting frame 104 are close to the conveying surface 3 of the straightening conveyor, this is the scoring and beveling station; when the open and closed ends of the mounting frame 104 are away from the conveying surface 3 of the straightening conveyor, this is the ingot removal station. The ingot 2 is conveyed via a straightening conveyor. The scoring mechanism 105 rolls the top edge of the ingot 2, forming multiple cuts spaced two-by-two along its length. The beveling mechanism 106 then bevels the top edge of the ingot 2, allowing the cut waste to naturally separate into segments and fall, preventing waste from piling up. When the equipment becomes blocked, the linear drive mechanism 101 drives the opening and closing ends of the mounting bracket 104 toward the conveying surface 3 away from the straightening conveyor, causing the two scoring and beveling units 1 to open in a figure-eight shape. That is, the opening and closing ends of the mounting brackets 104 in the two scoring and beveling units 1 move away from each other. At this point, the scoring mechanism 105 and beveling mechanism 106 are spaced away from the waste ingot, completely opening the space above the conveying surface 3. This, in turn, means that the space above the ingot 2 is completely open, freeing up operating space for removing the waste ingot and facilitating its hoisting and removal. This reduces processing time and improves work efficiency. After the waste ingot is taken out, the linear drive mechanism 101 drives the opening and closing end of the mounting frame 104 to move toward the conveying surface 3 close to the straightening conveyor, that is, the two notching and beveling units 1 are closed to continue processing the conveyed ingot 2.
