Description

Technical Field

[0001] The utility model relates to the technical field of blank roll processing, in particular to an automatic annealing device for blank roll processing. Background Technique

[0002] A roll is the main working component and tool on a rolling mill that causes continuous plastic deformation of metal. It mainly consists of a roll body, roll necks, and shaft heads. Annealing is a metal heat treatment process, which means heating the metal slowly to a certain temperature, maintaining for a sufficient time, and then cooling at an appropriate speed. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize dimensions, reduce the tendency of deformation and cracks, refine grains, adjust the structure, and eliminate tissue defects. By performing the annealing process on the roll necks, the overall performance of the roll can be enhanced, which is beneficial to the stable use of the roll.

[0003] Currently, when annealing a blank roll, due to the high temperature during annealing, after the heating is completed, the common method is to let it cool naturally by leaving the heating chamber or to assist in cooling by means of a fan. Although the annealing cooling does not require a high speed, when using multiple fans for cooling, the time is still relatively long. Moreover, when annealing multiple rolls simultaneously, the fans cannot cool them evenly, resulting in uneven cooling of the inner and outer sides, thus affecting the overall cooling efficiency.

[0004] Therefore, we propose an automatic annealing device for blank roll processing to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic annealing device for blank roll processing. When using this automatic annealing device, first, it is placed on the table to be processed and transported to the heating box by a push plate for high-temperature heating. After the heating is completed, when the push plate reaches the limiting wall, the moving push plate is blocked by the built-in blocking block, and the heated roll is suspended in the adjusting wall. Then, it enters the pre-prepared cooling water tank through lifting for uniform cooling to ensure the synchronous cooling of multiple rolls, thereby improving the overall cooling efficiency, enabling multiple rolls to complete cooling simultaneously, and thus completing annealing, so as to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

An adjusting wall is arranged at the middle end of the outer groove, and a cooling water tank is arranged on the inner side of the adjusting wall. A placing plate is arranged at the upper end of the workbench to be processed.

[0008] In a further embodiment, the push plate is arranged in a U shape, and the outer walls on both sides are slidably arranged in the outer groove.

[0009] In a further embodiment, the bottom end of the placing plate is a hollow plate, and the blank roll is placed on the placing plate, and the placing plate is arranged between the two outer walls of the push plate.

[0010] In a further embodiment, the inner sliding groove and the outer groove have the same length and are simultaneously arranged in the side walls of the heating box, the limiting wall and the workbench to be processed.

[0011] In a further embodiment, a blocking block is arranged in the inner wall at the upper end of the limiting wall, and an electric push rod is installed at the upper end of the blocking block.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1-7 , an automatic annealing device for blank roll processing, including a heating box 1, which is an existing heating chamber. During heating, the internal temperature can be manually controlled at 50 - 100 °C. When in use, first place the rolls on the placing plate 14 in sequence and then put them into the notch of the workpiece table 4. The placing plate 14 is divided into upper and lower layers. The upper layer is for fixing the rolls, and the two sides of the lower layer are relatively prominent, and the width is exactly the length of the two outer grooves 8, so that it can be inserted into the outer grooves 8 and slide. The width of the placing plate 14 is determined by the length of the roll, but all widths are the same;

[0028] After placing the placing plate 14, start the electric screw rod 6 to drive the push plate 5 to move at this time. The placing plate 14 is placed in the middle of the U-shaped push plate 5. Therefore, when the push plate 5 moves, it can push the placing plate 14 to move. When moving, the connection between the push plate 5 and the electric screw rod 6 slides on the inner chute 7, and the front end slides in the outer groove 8. When the placing plate 14 slides into the heating box 1, it descends through the sliding threaded blocks arranged on both sides of the electric sealing door 2 to seal the front end, and then heating can start;

[0029] During the process, it is necessary to push the blocking block 12 to descend by the electric push rod 13 installed in the limiting wall 3. Then, after heating is completed, the push plate 5 will push the placing plate 14 to move in the reverse direction. When it moves to the position of the descended blocking block 12, it will be blocked and unable to move. At this time, after the electric lifting rod 11 arranged at the lower end of the adjusting wall 9, the placing plate 14 stopped here will follow the adjusting wall 9 to descend, so as to enter the cooling water tank 10 to be cooled evenly. When the cooling is over, raise the adjusting wall 9 and the blocking block 12, and then the push plate 5 can continue to drive the placing plate 14 to move forward to reach the position of the workpiece table 4.

[0030] The working principle of the present utility model is as follows: As shown in the figure, it includes a heating box 1, which is an existing heating chamber. During heating, the internal temperature can be manually controlled at 50 - 100 °C. When in use, first place the rollers on the placing plate 14 in sequence and then put them into the notch of the workpiece table 4. The placing plate 14 is divided into upper and lower layers. The upper layer is for fixing the rollers, and the two sides of the lower layer are relatively prominent, and the width is exactly the length of the two outer grooves 8, so that it can be embedded in the outer grooves 8 and slide. The width of the placing plate 14 is determined by the length of the rollers, but all widths are the same. After placing the placing plate 14, start the electric screw rod 6 to drive the pushing plate 5 to move. The placing plate 14 is placed in the middle of the U-shaped pushing plate 5. Therefore, when the pushing plate 5 moves, it can push the placing plate 14 to move. When moving, the connection between the pushing plate 5 and the electric screw rod 6 slides on the inner chute 7, and the front end slides in the outer groove 8. When the placing plate 14 slides into the heating box 1, it drops through the sliding threaded blocks arranged on both sides of the electric sealing door 2 to seal the front end, and then heating can start. During the process, it is necessary to push the blocking block 12 to descend by the electric push rod 13 installed in the limiting wall 3. Then, after heating is completed, the pushing plate 5 will push the placing plate 14 to move in the reverse direction. When it moves to the position of the dropped blocking block 12, it will be blocked and unable to move. At this time, after the electric lifting rod 11 arranged at the lower end of the adjusting wall 9, the placing plate 14 stopped here will follow the adjusting wall 9 to descend, so as to enter the cooling water tank 10 for uniform cooling. When the cooling is over, raise the adjusting wall 9 and the blocking block 12, and then continue to drive the placing plate 14 to move forward by the pushing plate 5 to reach the workpiece table 4.
