Technical Field

[0001] The utility model relates to the technical field of high-strength alloy steel production equipment, in particular to a high-strength alloy steel quenching device. Background Art

[0002] Low-alloy high-strength steel refers to low-alloy engineering structural steel that adds a small amount of alloying elements to low-carbon steel so that the yield strength in the rolled or normalized state exceeds 275MPa. This type of steel is mainly used to manufacture various engineering structures that require higher strength, such as bridges, ships, vehicles, high-pressure vessels, oil and gas pipelines, large steel structures, etc. When using high-strength alloy steel to prepare workpieces, the workpieces need to be processed, among which quenching is a more important process.

[0003] The existing high-strength alloy steel quenching device usually hoists the workpiece into a pool filled with water when quenching the workpiece, and uses the water temperature to cool and quench the high-strength alloy steel workpiece. However, during the hoisting process, the workpiece is prone to accidentally fall into the cooling pool, and it is not convenient to salvage the workpiece after falling into the cooling pool. In addition, the quenching position of the workpiece is mostly the same place in the cooling pool each time, which makes it easy for the water temperature at the quenching point to rise and affect the cooling effect. For this reason, we propose a high-strength alloy steel quenching device. Utility Model Content

[0025] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0026] Example:

[0027] like Figure 1-Figure 5 As shown, a high-strength alloy steel quenching device comprises:

[0028] A quenching tank 1, a support leg 2 for support is fixedly connected to the bottom of the quenching tank 1, a control box 6 is fixedly connected to the front side of the quenching tank 1, and a sewage pipe 5 for discharging impurities such as carbon slag is fixedly connected to the bottom of the quenching tank 1;

[0029] A lifting mechanism 3 is arranged inside the quenching pool 1 and is used to protect the high-strength alloy steel during quenching and cooling and to collect workpieces that have accidentally fallen;

[0030] The tumbling assembly 4 is arranged at the rear side of the quenching tank 1 and is used to stir the cooling water inside the quenching tank 1 so that the cooling water in the quenching tank 1 surges.

[0031] The working principle of the above technical solution is as follows:

[0032] The high-strength alloy steel workpiece is quenched and cooled under the action of the quenching pool 1. If the workpiece accidentally falls, the falling workpiece is blocked under the action of the grid 305, and then the double-axis motor 311 is started. The double-axis motor 311 drives the worm 310 to rotate through the output shaft, and the worm 310 drives the worm wheel 312 to rotate, thereby driving the winding roller 304 to rotate through the transmission rod 306, thereby driving the grid 305 to move upward through the rope 308 until the workpiece is exposed to the water surface, and the workpiece can be picked up at this time;

[0033] Under the action of the air compressor 403, air can be blown into the quenching pool 1 through the pipeline 402, the main pipe 401 and the branch pipe 404. Under the action of the gas, the water in the quenching pool 1 surges, and the water in the quenching pool 1 flows during the surge, so that the water temperature is more uniform.

[0034] In another embodiment, if Figure 2 As shown, the lifting mechanism 3 includes a grille 305, which is arranged on the inner side of the quenching pool 1, and ropes 308 are fixedly connected to the left and right sides of the top of the grille 305, and wheel grooves 307 are opened on the left and right sides of the top of the quenching pool 1. The inner side of the wheel groove 307 is movably connected to a transmission rod 306 through a bearing, and the outer side of the transmission rod 306 is fixedly connected to a winding roller 304.

[0035] The fallen workpiece is received under the action of the grid 305 , the grid 305 can be driven to move upward under the action of the rope 308 , and the winding roller 304 can be driven to rotate under the action of the transmission rod 306 to wind up the rope 308 .

[0036] In another embodiment, if Figure 3 As shown, a dual-axis motor 311 is fixedly connected to the rear side of the quenching pool 1, and the dual-axis motor 311 is fixedly connected to a worm 310 through an output shaft. The rear end of the transmission rod 306 passes through the wheel groove 307, and the rear end of the transmission rod 306 is fixedly connected to a worm wheel 312, and the outer side of the worm wheel 312 is meshed with the outer side of the worm 310.

[0037] Under the action of the dual-axis motor 311, the worm gears 310 on both sides can be driven to rotate at the same time, thereby driving the winding rollers 304 on both sides to rotate, winding the rope 308, and lifting the grille 305 upward steadily.

[0038] In another embodiment, if Figure 2 As shown, the rope 308 is fixedly connected to the outside of the winding roller 304 , and the two ends of the two worms 310 that are away from each other are movably connected to the L-shaped plate 303 through the bearing, and the L-shaped plate 303 is fixedly connected to the outside of the quenching pool 1 .

[0039] The winding roller 304 rotates to wind up the rope 308 , and supports the other end of the worm 310 under the action of the L-shaped plate 303 .

[0040] In another embodiment, if Figure 2 As shown, slide grooves 302 are provided on both sides of the quenching pool 1, and sliders 309 are fixedly connected to the left and right sides of the grille 305. The sliders 309 are slidably connected to the inner side of the slide grooves 302, and a stopper 301 is fixedly connected to the inner side of the quenching pool 1.

[0041] Under the action of the slider 309 and the slide groove 302 , the moving track of the grille 305 is limited, thereby ensuring that the grille 305 can only move in the up and down directions.

[0042] In another embodiment, if Figure 4 As shown, the tumbling assembly 4 includes a main pipe 401, which is fixedly connected to the rear side of the quenching tank 1, and a branch pipe 404 is fixedly connected to the front side of the main pipe 401. The front end of the branch pipe 404 passes through the rear side of the quenching tank 1 and extends into the interior of the quenching tank 1. Aeration heads 405 distributed at equal intervals are arranged on the top of the branch pipe 404, and an air compressor 403 is arranged on the left side of the quenching tank 1.

[0043] Air can be blown into the pipe 402 by the air compressor 403 , and the air blows the water in the quenching tank 1 through the main pipe 401 , the branch pipe 404 and the aeration head 405 , thereby causing the water to surge and flow.

[0044] In another embodiment, if Figure 3 As shown, the air outlet of the air compressor 403 is fixedly connected to a pipe 402 , the other end of the pipe 402 passes through the outside of the main pipe 401 and is fixedly connected to the outside of the main pipe 401 , and a filter screen 406 is arranged on the top of the branch pipe 404 .

[0045] The filter 406 can protect the aeration head 405, thereby preventing the aeration head 405 from being blocked by debris.

[0046] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
