Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] refer to Figure 1-Figure 4 , a wear-resistant steel ball constant temperature quenching device provided by the utility model includes a quenching pool 1, a constant temperature adjustment component is arranged in the quenching pool 1, and the constant temperature adjustment component includes a heating element 3, a cooling component 4, a temperature detection component 5 and a control component 6.

[0038] refer to Figure 1-Figure 4 The heating element 3 is used to heat the cooling water in the quenching pool 1 so that the temperature of the cooling water reaches the set range of the steel ball quenching. The heating element 3 includes at least two steam branch pipes 31 and a main steam pipe 32 for simultaneously introducing hot steam into the at least two steam branch pipes 31. The at least two steam branch pipes 31 are laid in the quenching pool 1 along the width of the quenching pool 1. The main steam pipe 32 is provided with a first pneumatic valve 33, which is used to automatically control the opening and closing of the main steam pipe 32.

[0039] refer to Figure 1-Figure 4When the temperature of the cooling water in the quenching pool 1 is higher than the quenching set temperature range, the cooling assembly 4 is used to pump cooling water into the quenching pool 1. The cooling assembly 4 cooperates with the heating element 3 to control the temperature of the cooling water in the quenching pool 1 within the set temperature range, thereby improving the quenching quality. The cooling assembly 4 includes a cold water branch 41 for pumping cold water into the quenching pool 1, a plurality of water outlet pipes 42 arranged along the length of the cold water branch 41, and a main water inlet pipe 43 for pumping cooling water into the cold water branch 41. The number of the cold water branches 41 is at least two and they are erected on the quenching pool 1 along the width direction of the quenching pool 1. A second pneumatic valve 44 is arranged on the main water inlet pipe 43.

[0040] refer to Figure 1-Figure 4 The lengths of the steam branch pipe 31 and the cold water branch pipe 41 are both less than or equal to half the length of the quenching pool 1, and the outer edges of the steam branch pipe 31 and the cold water branch pipe 41 are coated with an anti-rust layer. The anti-rust layer protects the steam branch pipe 31 and the cold water branch pipe 41 and prolongs their service life.

[0041] refer to Figure 1-Figure 4 The temperature detection component 5 is arranged at the discharge end of the quenching pool 1. The temperature detection component 5 includes a first temperature detector 51 and a second temperature detector 52. The first temperature detector 51 is used to detect the minimum temperature set in the quenching pool 1 and to control the start and stop of the first pneumatic valve 33. The second temperature detector 52 is used to detect the maximum temperature set in the quenching pool 1 and to control the start and stop of the second pneumatic valve 44.

[0042] refer to Figure 1-Figure 4 The first pneumatic valve 33 , the second pneumatic valve 44 , the first temperature detector 51 and the second temperature detector 52 are all connected to the control component 6 by signals.

[0043] refer to Figure 1-Figure 4When the quenching pool of this structure quenches the steel ball, due to the high temperature of the steel ball, after the steel ball is quenched for a long time, the second temperature detector 52 arranged at the discharge end of the quenching pool 1 detects that the water temperature at the discharge end of the quenching pool 1 is higher than the set temperature, then the temperature of the cooling water at the feed end of the quenching pool 1 is higher than the maximum quenching temperature. At this time, the control component 6 controls the second pneumatic control valve 44 to open automatically, and adds water to the quenching pool 1 through the cooling component 5 until the water temperature meets the process requirements. The second pneumatic valve 44 is automatically closed. Therefore, the temperature of the discharge end of the quenching pool is detected by the second temperature detector to determine whether the cooling water in the quenching pool meets the process requirements of the quenching treatment, and then the cooling component is controlled whether to add cooling water to the quenching pool for mixing. The entire quenching process does not require manual operation and has a high degree of automation. Among them, since the length of the quenching pool 1 is relatively long and the temperature of the steel ball to be quenched is relatively high, after the steel ball is quenched by the quenching pool 1, the temperature in the quenching pool 1 changes greatly, that is, the water temperature in the front half of the quenching pool 1 along the feeding direction is higher than that in the rear half. This temperature change will also affect the quenching quality of the steel ball. Therefore, by making the length of the steam branch pipe 31 and the cold water branch pipe 41 less than or equal to one-half the length of the quenching pool 1, in this example, the length of the steam branch pipe 31 and the cold water branch pipe 41 are both equal to one-half the length of the quenching pool 1. The setting of this structure can increase the supplementary area or heating area of ​​the cooling water in the quenching pool 1. Compared with the existing water adding component at the feed end of the quenching pool 1, the setting of this structure can make the added cooling water quickly mix with the cooling water in the quenching pool, so that the temperature of the cooling water quickly reaches the set temperature range, avoiding the occurrence of high or low local temperature in the quenching pool 1, affecting the quenching treatment of the steel ball.

[0044] However, if the temperature of the cooling water is lower than the set quenching temperature during a brief shutdown, hot steam can be introduced into the steam branch pipe 31 through the main steam pipe 32 to heat the steam branch pipe 31, thereby heating the cooling water in the quenching pool 1 until the first temperature detector 51 detects that the temperature of the cooling water in the quenching pool 1 reaches the quenching temperature range, and transmits a signal to the control component 6, which controls the first pneumatic valve 33 to close, thereby stopping the introduction of steam into the steam branch pipe 31 to heat the cooling water until the set temperature range is reached.

[0045] refer to Figure 1-Figure 4 The quenching pool 1 is provided with a plurality of stirring components 7 for stirring the cooling water along its circumference. The cooling water is stirred by the stirring components 7 so that the added cooling water is quickly blended with the cooling water in the quenching pool and adjusted to the quenching set temperature.

[0046] refer to Figure 1-Figure 4An overflow pipe 8 is provided at the upper part of the discharge end of the quenching pool 1, and a drain valve 9 is provided on the overflow pipe 8. A liquid level detector 10 for detecting the water level in the quenching pool 1 and controlling the start and stop of the drain valve 9 is provided at the discharge end of the quenching pool 1. The liquid level detector 10 and the drain valve 9 are both connected with the control component signal. Through the setting of this structure, the cooling water of the quenching pool 1 that exceeds the set liquid level can be automatically discharged from the overflow pipe 8 to the cooling water storage in time, so as to avoid the cooling water in the quenching pool 1 from overflowing along the circumferential edge of the quenching pool 1 to the bottom surface of the working environment.

[0047] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
