Problems solved by technology

[0003] When the existing quenching device is in operation, when maintaining the quenching temperature, the temperature is maintained by adding fuel in a timely and appropriate manner. However, if the fuel is injected improperly, the temperature will rise rapidly, making it difficult to control the temperature, and then affecting the quenching effect. At the same time, a large amount of steam generated during cooling can not be well utilized, resulting in waste of energy

Embodiment 1

[0025] Example 1, such as figure 1 , Figure 3-4 , before quenching, start the furnace 2 for preheating, and at the same time, place the hubs that need to be quenched one by one on the disc 8 where the bumps are set, and through the intervals of the bumps, each hub can be placed on the circle at intervals Disk 8, when each wheel hub is quenched, it will not affect each other, which facilitates the loading and unloading of the wheel hub. When quenching, the wire roller 5 drives the supporting plate 6 to move upward under the drive of the motor 4. After the rectangular frame is placed inside the heating chamber 9, a closed space is formed between the heating chamber 9 and the supporting plate 6, and an insulation layer 16 is arranged inside the heating chamber 9 to ensure that the internal temperature of the heating chamber 9 is stable, and the wheel hub can be well maintained. Quenching treatment.

Embodiment 2

[0026] Example 2, such as figure 2, when the inside of the furnace 2 is heated, as the internal air pressure increases, when the air pressure reaches a certain value, the baffle plate 11 will be pushed away, and hot air will be sent out to heat the inside of the heating chamber 9, while part of the heat The air flow enters the heat recovery pipe 13, rotates by driving the fan wheel 14, and under the drive of the fan wheel 14, flows back into the furnace 2, so that the air pressure of the heating chamber 9 can be reduced, and at the same time, the returned hot air flow is generated on the inside of the furnace 2. The supercharging effect allows the fuel inside the stove 2 to be fully burned, improving the utilization efficiency of the fuel.

Embodiment 3

[0027] Example 3, such as figure 1 , when the pallet 6 descends, the heat-treated wheel hub contacts the cooling liquid inside the cooling pool 17 and generates a large amount of steam. Since the cooling pool 17 is set below the ground, the steam that escapes upwards is drawn out by the ventilation equipment 18 and sent to Cooperate with the outside, and then use it to improve energy utilization efficiency. At the same time, due to the influence of the location of the cooling pool 17, the ventilation equipment 18 will not be set at an excessively high position, which improves the safety and facilitates the installation of the ventilation equipment 18. overhaul.

[0028] Working principle: After the hubs to be quenched are placed equidistantly on the disc 8 through the bumps set on the disc 8, each hub can be placed on the disc at intervals through the bumps, so that each hub can be quenched. During quenching, they will not affect each other, which facilitates the loading and ...

Abstract

The invention discloses an automatic quenching device for a demolded motorcycle aluminum alloy hub. The automatic quenching device comprises a base, wherein a furnace is fixedly installed at the top of the base, a heating chamber is fixedly installed on one side of the furnace, a motor is fixedly installed at the top of an inner cavity of the heating chamber, and wire rollers are fixedly installedat the output end of the motor; a supporting plate is installed on the wire rollers through steel cables in a transmission manner, a supporting column is fixedly installed in the supporting plate, and discs are fixedly installed on the outer surface of the supporting column. According to the automatic quenching device, resistance is provided by arranging baffles and elastic force of springs, whenthe temperature in the furnace reaches a certain degree, the baffles can be burst through, it is ensured that fire power during quenching meets the process requirement, meanwhile, a heat return pipeline is connected between the furnace and a heating pipeline, hot air can flow back into the furnace, the temperature in the furnace can be stabilized, then the fuel consumption is effectively reduced,steam generated during cooling is fed in through ventilation equipment and used in cooperation with external equipment, and the energy utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to an automatic quenching device for an aluminum alloy wheel hub of a motorcycle after demoulding. Background technique [0002] The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), keep it warm for a period of time to make it fully or partially austenitized, and then cool it with a cooling rate greater than the critical cooling rate. Rapid cooling to below Ms (or near Ms isothermal) heat treatment process for martensite (or bainite) transformation, usually also solid solution treatment of aluminum alloy, copper alloy, titanium alloy, tempered glass and other materials or with The heat treatment process of rapid cooling process is called quenching. [0003] When the existing quenching device is in operation, when maintaining the quenching temperature, the temperature is maintained...
