Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgy, and in particular relates to a high alloy online quenching device. Background Art

[0002] Quenching is a heat treatment method in metallurgical processing. Quenching can transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure, which is then combined with tempering at different temperatures to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the steel. Quenching can also meet the special physical and chemical properties requirements of certain special steels such as ferromagnetism and corrosion resistance.

[0003] In conventional metal hot rolling production lines, the heated metal wire needs to be quenched. Currently, quenching is generally done by workers manually pulling the wire. Due to the heavy weight of the metal coils, manual pulling is labor-intensive and has low production efficiency. At the same time, due to the high temperature during the quenching process, there are certain safety hazards when workers manually quench the wire. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Reference Figure 1-2 A high-alloy online quenching device includes two groups of bases 1, and gantries 3 are mounted on the two groups of bases 1. Pulley blocks 8 are provided on both sides of the top of the gantry 3, and a guide pulley 9 is provided at the middle of the top of the gantry 3. A lifting cylinder 10 is provided on the base 1 on the left side of the gantry 3, and a lifting frame 2 is provided on the inside of the gantry 3. The lifting cylinder 10 is connected with a lifting steel cable, and the lifting steel cable is connected to the lifting frame 2 in turn through the pulley block 8 and the guide pulley 9. A conveying roller 4 is provided at the bottom of the lifting frame 2, and a first transmission gear 5 is provided on the side of the conveying roller 4. A traveling motor 6 is installed on the base 1 on the right side of the gantry 3, and a second transmission gear 7 is connected to the output shaft of the traveling motor 6.

[0017] In view of the problem that the existing hot-rolled wire requires workers to manually control the pulling and quenching, which is labor-intensive and has safety hazards, the present technical solution proposes an online quenching device, which includes two groups of bases 1. The two groups of bases 1 are installed above the water pool used for quenching. A gantry 3 is set between the two groups of bases 1. A lifting frame 2 is set on the inner side of the gantry 3, and a lifting cylinder 10 is set on the left side of the base 1. A lifting steel cable is set on the lifting cylinder 10. The lifting steel cable is connected to the lifting frame 2 after being guided by the transmission of the pulley group 8 and the guide pulley 9. The lifting frame 2 is driven to move up and down by the lifting cylinder 10. When the high-temperature wire passes through the lifting frame 2, the lifting cylinder 10 drives the lifting frame 2 to descend, thereby placing the high-temperature wire into the water pool for quenching. After quenching is completed, the lifting cylinder 10 can drive the lifting frame 2 to rise and reset. After the lifting frame 2 is reset, the traveling motor 6 is started to drive the conveying roller 4 to rotate, and the wire on the lifting frame 2 is automatically transferred out.

[0018] Furthermore, the first transmission gear 5 is meshedly connected with the second transmission gear 7 .

[0019] Through this technical solution, the first transmission gear 5 of the conveying roller 4 can engage with the second transmission gear 7 of the traveling motor 6. After the quenching reset is completed, the traveling motor 6 can drive the conveying roller 4 to rotate, thereby realizing online transportation of the quenched wire. This technical solution can be directly connected to the production line automation, thereby greatly improving the production and processing efficiency.

[0020] Furthermore, a lifting groove is provided in the gantry 3, and a limiting guide wheel is provided on the lifting frame 2, and the limiting guide wheel is stuck in the lifting groove.

[0021] Through this technical solution, the limiting guide wheel on the lifting frame 2 is stuck inside the lifting groove, thereby limiting the movement of the lifting frame 2, so that the lifting frame 2 can stably perform lifting and lowering movements along the lifting groove; the lifting frame 2 is stably lifted and lowered, and the immersion and lifting of materials are more stable. The movement of the lifting frame 2 is limited, so that after the lifting frame 2 is lifted, the first transmission gear 5 can be engaged with the second transmission gear 7.

[0022] Furthermore, a counterweight block 11 is connected to the pulley block 8 on the right side via a counterweight steel cable.

[0023] The counterweight block 11 can provide an upward pulling force to the lifting frame 2, thereby making the driving of the lifting cylinder 10 more labor-saving. The counterweight block 11 can also make the lifting movement of the lifting frame 2 more stable and have a better use effect.

[0024] Furthermore, the pulley block 8 on the left side is provided with three sets of pulleys, and the pulley block 8 on the right side is provided with two sets of pulleys.

[0025] Through this technical solution, the pulley group 8 on the left is provided with three groups of pulleys, and the pulley group 8 on the right is provided with two groups of pulleys, among which the middle group of pulleys in the middle left pulley group 8 is arranged side by side with the guide pulley 9. Similarly, four hooks are provided at the four corners of the top of the lifting frame 2, which are respectively connected to the remaining four groups of pulleys on the left and right sides. Specifically, the steel cables of the two groups of pulleys on the left are grounded, which are used to limit the lowest position of the lifting frame 2, and the two groups of pulleys on the right are connected to the counterweight block 11 through the counterweight steel cable.

[0026] Working principle: A lifting cylinder 10 is provided on the left side of the base 1, and a lifting steel cable is provided on the lifting cylinder 10. The lifting steel cable is connected to the lifting frame 2 after being guided by the pulley group 8 and the guide pulley 9. The lifting frame 2 is driven to move up and down by the lifting cylinder 10, and then the high-temperature wire is driven to move up and down, and the high-temperature wire is automatically placed in the water pool to complete quenching. A conveying roller 4 is provided at the bottom of the lifting frame 2, and the conveying roller 4 can be driven to move by the travel motor 6 to transfer the quenched metal wire out; this technical solution not only realizes the automatic immersion and lifting of the high-temperature wire, completes the automatic quenching of the high-temperature wire, but also realizes the online transportation of the wire after quenching is completed. This equipment automatically completes the quenching and transportation of the wire, saves manpower and material resources, improves production and processing efficiency, and at the same time reduces production safety risks, and has a better use effect.
