Description

Technical Field

[0001] This utility model relates to the field of quenching and cooling technology, specifically to a novel cooling mechanism. Background Technology

[0002] In the heat treatment process of automotive wheel hubs, the quenching process is a key step that determines the mechanical properties of the product. Currently, the traditional quenching mechanism commonly used in the industry relies on the design of "guide wheel submersion," which guides the workpiece to complete the quenching action by immersing the guide wheel in the quenching liquid. However, this design has certain drawbacks in practical applications. The guide wheel is not only susceptible to corrosion and rust due to long-term immersion in the quenching water tank, but also prone to accelerated wear due to impurities in the quenching liquid, reducing the guiding accuracy and increasing production costs due to frequent replacements. Moreover, in order to facilitate the transportation of automotive wheel hubs, there is no protective obstruction during the quenching process, which makes them susceptible to the risk of displacement and falling due to external forces such as vibration. Therefore, a new type of cooling mechanism is urgently needed. Utility Model Content

[0032] Conveying rollers 9, there are several conveying rollers 9, which are rotatably mounted on several layers 6-1 of the multi-layer quenching frame 6 via bearings. The multi-layer quenching frame 6 is provided with a synchronous drive assembly 10 connected to several conveying rollers 9, and a guard assembly 11 is provided on the multi-layer quenching frame 6.

[0033] The synchronization drive component 10 includes:

[0034] Motor No. 3 10-1 is fixedly installed on the upper part of the multi-layer quenching rack 6. A vertical rod 10-2 is fixedly installed on the output shaft of motor No. 3 10-1.

[0035] Several worm gears 10-3 are fixedly sleeved on the left ends of several conveying rollers 9. A worm 10-4 is rotatably mounted on the left side wall of the shelf 6-1 via a bearing. The worm 10-4 meshes with the worm gears 10-3. The front end of the worm 10-4 is connected to the vertical rod 10-2 via a bevel gear 11-7.

[0038] Rotating rod 11-5, there are several rotating rods 11-5, which are respectively rotatably installed on the left and right sides of the front and rear side walls of several shelves 6-1 through bearings. A connecting rod 11-6 is fixedly sleeved on the rotating rod 11-5, and the upper end of the connecting rod 11-6 is hinged to the slider 11-2.

[0039] Gears 11-7, there are several gears 11-7, which are fixedly sleeved on one end of several rotating rods 11-5, and the gears 11-7 are located on the outside of the multi-layer quenching frame 6.

[0040] When using this invention, the vehicle wheel hub is placed on the conveyor roller 9. Then, the first motor 4 is started, which drives the first lead screw 17 to rotate, causing the internal thread block 5 to move the traveling frame 2 to the left, so that the traveling frame 2 moves above the quenching water tank 1. Then, the second motor 7 is started, which drives the second lead screw 8 to rotate, causing the multi-layer quenching frame 6 to move downward into the quenching water tank 1. The multi-layer quenching frame 6, through the conveyor roller 9, moves the vehicle wheel hub into the quenching water tank 1 for quenching. During the downward movement of the multi-layer quenching frame 6, the gear 11-7 meshes with the rack 11-8 in a fixed state and drives the rotating rod 11-5 to rotate. The rotating rod 11-5 drives the connecting rod 11-6 to flip, causing the slider 11-2 to slide to the other side in the slide groove 12 and push the crossbar 11-1 upward, thereby achieving the front and rear stops of the vehicle wheel hub on the conveyor roller 9. The limiting block 11-4 can be pushed into the groove 13 by the spring 11-3 to limit the slider 11-2 in this state. After the quenching of the vehicle wheel hub is completed, the second motor 7 drives the second lead screw 8 to rotate in the opposite direction, so that the multi-layer quenching frame 6 moves upward to the top of the quenching water tank 1. With the cooperation of gear 11-7, rack 11-8, rotating rod 11-5, connecting rod 11-6 and slider 11-2, the horizontal stop bar 11-1 moves downward to cancel the protection of the vehicle wheel hub. Then the third motor 10-1 can be started. The third motor 10-1 drives the vertical rod 10-2 to rotate. The vertical rod 10-2 drives several worm gears 10-4 to rotate through the bevel gear 11-7. The worm gears 10-4 drive the conveyor roller 9 to rotate through the worm wheel 10-3. The rotation of the conveyor roller 9 realizes the conveying of the vehicle wheel hub and transfers the vehicle wheel hub to the next process.

[0041] Compared with the prior art, the beneficial effects of this utility model are:

[0042] With the cooperation of No. 1 motor 4, internal thread block 5, multi-layer quenching frame 6, No. 2 motor 7, No. 2 lead screw 8, conveying roller 9 and synchronous drive assembly 10, not only can convenient conveying of vehicle wheel hubs be achieved, but also no parts need to be immersed in quenching liquid for a long time, effectively improving service life.

[0043] With the cooperation of the guard component 11, the horizontal bar 11-1 can provide protection for the vehicle wheel hub during the quenching process of the multi-layer quenching rack 6 moving down into the quenching water tank 1, thus preventing the vehicle wheel hub from shifting and falling off.

[0044] The bearing housing 16 can provide support for the left end of the first lead screw 17, thereby effectively improving the stability of the first lead screw 17.

[0045] The guide rail 14 can provide movement guidance for the guide wheel 3, preventing the movement of the traveling frame 2 from deviating in position.
