Technical Field
[0001] The utility model relates to the technical field of rolling rollers, in particular to an energy-saving rolling roller quenching device. Background Art
[0002] At present, the surface layer of the roller is subjected to higher stress than the core during operation. In the case of friction, the surface layer is constantly worn, so the surface layer of the roller is required to have high strength, high hardness, high wear resistance and high fatigue limit. Only surface strengthening can meet the above requirements. Surface quenching is widely used in production because of its advantages of small deformation and high productivity.
[0003] The existing quenching device can only perform quenching processing on the rollers one by one at a time, and cannot operate the rollers in batches at one time. Each single quenching results in low quenching efficiency of the rollers, and each single quenching of the rollers will also cause a large amount of heat resources to be wasted.
[0004] Therefore, we propose an energy-saving roll quenching device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-3The utility model provides a technical solution: an energy-saving roll quenching device, comprising a machine body shell 1 and multiple groups of rolls 2 arranged in the inner cavity of the machine body shell 1, a plurality of grooves adapted to the rolls 2 are opened on the surface of the connecting seat 8, multiple rolls 2 are clamped between two groups of connecting seats 8, multiple rolls 2 are locked and fixed, the electric guide rail 3 is started, and the slider of the electric guide rail 3 drives the lifting column 4 and the connecting plate 5 to move, when the two groups of connecting plates 5 move to the top of the heating shell 6, the lifting column 4 is started, and the lifting column 4 pushes the connecting plate 5 to When the connecting plate 5 moves downward, it also drives the rotating seat 11 and the connecting seat 8 to move downward. When the connecting seat 8 moves downward, it also drives the rollers 2 to move downward. Multiple rollers 2 enter the inner cavity of the heating shell 6. At this time, multiple groups of heating nozzles 9 fixedly connected to the inner wall of the heating shell 6 are started. The multiple groups of heating nozzles 9 heat the placed rollers 2 at high temperature. At the same time, the rotating seat 11 drives the connecting seat 8 to rotate and also drives the rollers 2 to rotate, so as to ensure that the rollers 2 are heated evenly and multiple rollers 2 can be heated at one time.
[0022] For details, please refer to Figure 1-3 After the heating of the rollers 2 is completed, the connecting plate 5 and the connecting seat 8 are moved again by the lifting column 4 and the electric guide rail 3. The connecting seat 8 is immersed in the coolant 10 set in the cooling pool 7, and the multiple groups of rollers 2 are also immersed in the coolant 10 to achieve cooling. The cooling pool 7 and the heat sink 12 are both set to heat-conducting materials to increase the contact area with the air, which can better discharge the heat and can reduce the temperature of the coolant 10 more quickly.
[0023] Working principle: The surface of the connecting seat 8 is provided with a plurality of grooves adapted to the rollers 2, and the plurality of rollers 2 are clamped between the two groups of connecting seats 8. After the plurality of rollers 2 are locked and fixed, the electric guide rail 3 is started, and the slider of the electric guide rail 3 drives the lifting column 4 and the connecting plate 5 to move. When the two groups of connecting plates 5 move to the top of the heating shell 6, the lifting column 4 is started, and the lifting column 4 pushes the connecting plate 5 to move downward. When the connecting plate 5 moves downward, it also drives the rotating seat 11 and the connecting seat 8 to move downward. When the connecting seat 8 moves downward, it also drives the rollers 2 to move downward, and the plurality of rollers 2 enter the inner cavity of the heating shell 6. At this time, the plurality of heating nozzles 9 fixedly connected to the inner wall of the heating shell 6 are started, and the plurality of heating nozzles 9 heat the placed rollers 2 at high temperature. At the same time, the rotating seat 11 drives the connecting seat 8 to rotate and also drives the rollers 2 The rollers 2 are rotated to ensure that the rollers 2 are heated evenly, and multiple rollers 2 can be heated at one time. After the rollers 2 are heated, the connecting plate 5 and the connecting seat 8 are driven to move again by the lifting column 4 and the electric guide rail 3. The connecting seat 8 is immersed in the coolant 10 set in the cooling pool 7, and multiple groups of rollers 2 are also immersed in the coolant 10 to achieve cooling. The cooling pool 7 and the heat sink 12 are both set to heat-conducting materials to increase the contact area with the air, which can better discharge the heat and reduce the temperature of the coolant 10 more quickly. This solves the problem that the existing quenching device can only perform quenching processing on the rollers 2 at a time, and cannot operate the rollers 2 in batches at a time. Each single quenching leads to low quenching efficiency of the rollers 2, and each time the rollers 2 are quenched individually, a large amount of heat resources are wasted.
