Description

Technical Field

[0001] The utility model relates to the technical field of engine connecting rod production, in particular to an engine connecting rod blank cooling device. Background Art

[0002] After forging, automotive engine connecting rod blanks require cooling. Currently, the most common cooling method involves placing the blank on a cooling rack and then using a fan to blow air through the blank. However, this cooling method has a drawback: the blank is often exposed to air from only one side during air cooling. This results in faster cooling on the windward side of the blank, while the leeward side struggles to cool effectively. This leads to uneven cooling throughout the blank, ultimately compromising the structural strength of the entire part. Utility Model Content

[0003] The purpose of the utility model is to provide an engine connecting rod blank cooling device in view of the above-mentioned shortcomings, which can make the connecting rod blank cooled more evenly and ensure the structural strength of the entire part.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A cooling device for an engine connecting rod blank comprises a base, a cover body with its bottom end fixed on the base and its opening facing forward, a bracket fixed at the opening of the cover body, a plurality of rotating seats equidistantly arranged on the bracket, a motor fixed on the bracket, a transmission structure used to connect the motor and the rotating seat, a hook fixed to the bottom of the rotating seat, a plurality of mounting openings provided on the back plate, a fan provided in each of the mounting openings, and an air outlet end of the fan arranged toward the bracket.

[0006] Furthermore, a rotating shaft is fixedly connected to the top of the rotating seat, a worm gear is fixed on the rotating shaft, and the rotating shaft is rotatably connected to the bracket; the transmission structure includes a reducer connected to the output shaft of the motor, a worm rotatably connected to the bracket, one end of the worm is connected to the output end of the reducer, and the worm is engaged with the worm gear.

[0007] Furthermore, a mesh plate is fixed in the cover body, a plurality of mesh holes are provided on the mesh plate, and the mesh plate is arranged facing the air outlet end of the fan.

[0008] Furthermore, the hook is covered with a non-slip rubber sleeve.

[0009] Furthermore, it also includes a controller fixed on one side of the cover body, and the motor and the fan are electrically connected to the controller.

[0010] The beneficial effects of the utility model are:

[0011] In actual application, the large-end holes or small-end holes of multiple connecting rod blanks to be cooled are hung on hooks respectively, and air is blown to the connecting rod blanks by a fan. At the same time, the motor drives the rotating seat to rotate through the transmission structure, so that the connecting rod blanks are evenly cooled. The utility model can make the connecting rod blanks cool more evenly, and ensure the structural strength of the entire part. BRIEF DESCRIPTION OF THE DRAWINGS
