Description

Technical Field

[0001] The utility model relates to the technical field of steel ball feeding devices, in particular to an automatic feeding device for heat treatment of steel balls. Background Art

[0002] Steel ball heat treatment is an important process to improve the performance of steel balls. Steel balls usually need to be heat treated during the manufacturing process to achieve specific hardness and strength requirements. Heat treatment can optimize the performance of steel balls by changing their microstructure, such as improving wear resistance, pressure resistance and corrosion resistance.

[0003] During the heat treatment process, the transportation of steel balls is an indispensable part of the whole process. Directly transporting steel balls by dumping will cause collisions between steel balls. Especially the surface of steel balls after heat treatment is prone to deformation, so collisions between steel balls can easily cause deformation. Secondly, guide rails are used for guided rolling transportation of steel balls, and the guide rollers are adapted to the size of the steel balls. Steel balls that are too small or too large cannot roll on their tracks, resulting in reduced practicality. Utility Model Content

[0007] Preferably, a servo motor is fixed on the outside of the conveying platform and at a position corresponding to the driving shaft, and the output end of the servo motor is fixed on the driving shaft.

[0008] Preferably, a cover plate is fixed on the outer side of the upper end of the adapter tube, an upper groove is opened at the upper opening of the discharge hole, the size of the upper groove is matched with the size of the cover plate, and magnetic blocks are fixed at the four corners of the bottom of the upper groove and are adsorbed and fixed to the bottom of the cover plate.

DETAILED DESCRIPTION

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example

[0020] A pair of driving shafts 22 are rotatably connected in the mounting groove 12, a driving sprocket 23 is fixed on the driving shaft 22, the conveying chain 2 is installed between the driving sprockets 23, a servo motor 24 is fixed on the outside of the conveying platform 1 and at a position corresponding to the driving shaft 22, and the output end of the servo motor 24 is fixed on the driving shaft 22.

[0021] A rotating rod 32 is rotatably connected inside the material tray 3, a push plate 33 is fixed at the bottom of the rotating rod 32, a driving motor 34 is fixed at the center of the material tray 3 at the bottom of the push plate 33 and the bottom of the material tray 3, and the output end of the driving motor 34 is fixed at one end inside the rotating rod 32, and the horizontal cross-section of the push plate 33 is a triangular structure.

[0022] In this embodiment, the entire device is first connected to an external power supply, and then the steel ball is placed in the material tray 3. The driving motor 34 is used to drive the rotating rod 32 to rotate, so that the push plate 33 can push the steel ball to roll in the material tray 3. When the steel ball moves to a position aligned with the discharge hole 31, a single steel ball can enter the adapter tube 41 and finally fall into the guide groove 11.
