Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, specifically to a high-efficiency quenching device. Background Technology

[0002] Rolls need to be quenched by a quenching device during production.

[0003] Chinese Patent CN105112640B discloses a roll quenching device, comprising a roll, a worktable, an adjusting seat, a roll mounting seat, and a lifting bracket. The roll passes through the worktable, its top end is connected to the roll mounting seat via the adjusting seat, and its bottom end is connected to the roll mounting seat. The roll mounting seat is mounted on the lifting bracket. A roller-type cooling water tank surrounding the roll is arranged on the worktable, and a thermal induction coil surrounding the roll is arranged above the roller-type cooling water tank. The roll quenching device of this invention features uniform rotation of the roll during heating to ensure even heating; a temperature measuring instrument controls the descent speed of the roll mounting seat to ensure complete quenching; the roller-type cooling water tank can accommodate rolls of various sizes, saving resources and manpower; and a protective device effectively blocks coolant splashing during quenching, protecting the roll journal from damage.

[0004] The above structure involves hoisting the roll between the protection device and the motor using hoisting equipment. However, the upper end of the roll is not designed with a clamping structure. When the hoisting equipment is being removed, the part of the hoisting equipment that contacts the roll is directly below the motor. External support equipment is needed to support the upper end of the roll before the hoisting equipment can be removed and then docking can be performed. Since the roll is quite long, it is easy for people to cause safety issues when supporting it with support equipment.

[0005] Based on this, the present invention designs a high-efficiency quenching device to solve the above problems. Utility Model Content

[0039] The clamping assembly 7 includes an arc-shaped clamping plate 71, a support frame 72, a rack 73, a synchronization module 74, a gear ring 75, and a connecting plate 76. The support frame 72 is fixedly installed at the bottom of the horizontal rotating assembly 6. The synchronization module 74 is fixedly connected to the side wall of the upright part of the support frame 72. The output end of the synchronization module 74 is fixedly connected to the rack 73. The rack 73 is meshed with the gear ring 75. The gear ring 75 is rotatably connected to the front end of the support frame 72 through a connecting shaft. The gear ring 75 is fixedly connected to the connecting plate 76 through a connecting shaft. The arc-shaped clamping plate 71 is fixedly connected to the outer end of the connecting plate 76.

[0040] Synchronous Module 74 is a bidirectional double-slider precision linear module with forward and reverse toothed ball screws.

[0041] The back plate 1 is fixedly connected to the rotation drive assembly 4 below the second drive assembly 8. The drive end of the rotation drive assembly 4 and the rotation end of the horizontal rotation assembly 6 are both connected to the end insertion assembly 5 for the insertion of the roll end.

[0042] The first drive assembly 2 moves the heat treatment assembly 3 to the lowest position. The second drive assembly 8 moves the horizontal rotation assembly 6 upward. The synchronous module 74 of the clamping assembly 7 moves the rack 73 outward. The rack 73 rotates the gear ring 75, which in turn rotates the connecting plate 76.

The connecting plate 76 drives the arc-shaped clamping plate 71 to rotate outward and open, so as to avoid the arc-shaped clamping plate 71 from affecting the movement of the heat treatment component 3. This facilitates the installation of the roll between the two sets of end plug-in components. The rotating driving component 4 drives the lower end plug-in component 5 to rotate. The two sets of end plug-in components 5 cooperate to drive the roll to rotate. At the same time, the heat treatment component 3 heats the roll. After the current part is treated, the first driving component 2 drives the heat treatment component 3 to move to the next part for treatment, so as to achieve high-efficiency quenching treatment of the roll.
