Abstract
The invention discloses a high temperature steel ball quenching device which is used for cooling high temperature steel balls. The quenching device comprises a water tank, a feeding mechanism arranged at one end of the water tank, a discharging mechanism arranged at the other end of the water tank, and a roller arranged in the water tank and used for conveying the high temperature steel balls. The roller is arranged in the water tank can rotate in the axial direction of the roller, and the inner surface of the roller is provided with an inner thread spirally distributed in the length direction of the roller. The quenching device further comprises a driving mechanism used for driving the roller to rotate and a constant temperature system arranged in the water tank. According to the high temperature steel ball quenching device, the high temperature steel balls are conveyed through the roller provided with inner thread, and therefore the high temperature steel balls can be cooled evenly and entirely when rolling forwards. Through an inner circulating mechanism, water kept in a constant temperature through the constant temperature system in the water tank is thrown into the roller so that the water contained in the roller can stay in a constant temperature state when the roller conveys the high temperature steel balls. The cooling speed and cooling efficiency of the steel balls are improved, the cooling effect is good, and the Rockwell hardness of the cooled steel balls is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is further elaborated.
Shown in Figure 1, above-mentioned a kind of high temperature steel ball 1 quenching unit, for cooling down high-temperature steel ball 1.This quenching unit includes being that the tank 2 of cuboid, the feeding mechanism 3(that is located at this tank 2 right-hand member are right-hand member here referring to the right in Fig. 1, Fig. 1), be located at the discharging mechanism 4 of this tank 2 left end, be located in this tank 2 for the cylinder 5 in the Steel ball conveyor that will tumble in this feeding mechanism 3 to this discharging mechanism 4.
What this cylinder 5 rotated around Pivot Point Center line direction is located in this tank 2, and this cylinder 5 inner surface is provided with the female thread of Spiral distribution along its length, the constant temperature system that this quenching unit also includes the driving mechanism for driving this cylinder 5 to rotate, is located in this tank 2.In the present embodiment, the axial line of this cylinder 5 is distributed in the horizontal direction, and namely lying of this cylinder 5 level is located in this tank 2.This driving mechanism is servomotor.Carry high temperature steel ball 1 by arranging the female cylinder 5 of tool in tank 2, make high temperature steel ball 1 roll advance in can overall uniform decrease in temperature, improve cooling efficiency and cooling-down effect.
This constant temperature system includes for waterborne in this tank 2 being risen to the heating-up mechanism 6 of operating temperature, being used for entering at high temperature steel ball 1 being down to the cooling mechanism 7 of operating temperature after in this tank 2 under water.Before work, it is generally required to temperature is risen to operating temperature, it is typically in about 150 DEG C, now by heating-up mechanism 6, the water in tank 2 is heated；And the temperature of high temperature steel ball 1 is typically in about 830 DEG C, after entering tank 2, in tank 2, water temperature raises rapidly, now by cooling mechanism 7, the water temperature in tank 2 is down to operating temperature.
This quenching unit also includes the samming rabbling mechanism 8 being located in this tank 2.Owing to high temperature steel ball 1 enters from the right side of this tank 2, and the steel ball after cooling of quenching exports from the left side of this tank 2, and therefore the water in this tank 2 can produce the phenomenon of non-uniform temperature, the cooling efficiency of impact entirety and cooling-down effect.By arranging this samming rabbling mechanism 8, it is possible to make the water of optional position in this tank 2 not produce the temperature difference, improve cooling efficiency and cooling-down effect.
This quenching unit also includes the internal recycle mechanism 9 for squeezing in this cylinder 5 by the water in this tank 2 being located in this tank 2.Advancing owing to high temperature steel ball 1 rolls with female thread in cylinder 5, therefore the water temperature in cylinder 5 is higher than the water temperature in cylinder 5 external flume 2.By arranging this internal recycle mechanism 9, it is possible to make the water in this cylinder 5 and this tank 2 not produce the temperature difference, improve cooling efficiency and cooling-down effect.
Set forth the work process of lower the present embodiment in detail below:
Start driving mechanism and constant temperature system, after the heating-up mechanism 6 operating temperature by the water temp. heating in tank 2 to 150 DEG C, the high temperature steel ball 1 of 830 DEG C is sent in tank 2 by feeding mechanism 3, high temperature steel ball 1 enters after in cylinder 5, advance in cylinder 5 from right to left under the effect of female thread, entering after cooling in discharging mechanism 4, now the water temperature in tank 2 raises, and the water temperature in tank 2 is cooled and maintained at the operating temperature of 150 DEG C by cooling mechanism 7.
