Description

Technical Field

[0001] The utility model relates to the technical field of steel shot processing, and more specifically to a steel shot quenching device. Background Art

[0002] In the process of processing steel shots, in order to improve the hardness of the steel shots, a quenching device is usually used to quench the steel shots. However, the commonly used steel shot quenching device rotates the entire device to roll the internal steel shots during use to ensure comprehensive quenching. However, when the steel shot quenching device rolls as a whole, the steel shots will frequently collide with each other with great force, causing damage and reducing safety. In addition, when the steel shots are discharged, a motor is required to drive the discharge, which increases power consumption.

[0003] For example, announcement number CN212982990U discloses a steel shot quenching device, which includes a base, two sets of support frames extending from the edges of the upper end of the base, the ends of the support frames are connected to a flipping mechanism, the interior of the flipping mechanism is embedded with a device body, and a connecting pipe extends through the middle of the upper end surface of the device body.

[0004] It can be seen from the above-mentioned public scheme that during the quenching process, the steel shots need to be turned over by the servo motor to drive the flipping mechanism to flip the entire device. During the flipping process, the internal steel shots will frequently collide with each other or strongly collide with the H-shaped rolling groove and the inner wall of the device body, which will cause damage to the surface of the steel shots and reduce the quenching safety of the steel shots. In addition, when the quenched steel shots are discharged, the brake motor is required to drive the transmission rod to rotate, and then drive the feeding blades to rotate and feed, which increases the consumption of electricity.
