Description

Technical Field

[0001] The utility model relates to the technical field of screw production equipment, in particular to a quenching and cooling device for the production of hydraulic oil pipe screws. Background Art

[0002] Hydraulic oil line screws are essential components in hydraulic systems, primarily used to connect oil lines, oil circuits, and other hydraulic components. They ensure smooth and sealed oil circuits, preventing leakage and air ingress, thereby ensuring the proper functioning of the hydraulic system. Hydraulic oil line screws come in a variety of types, including but not limited to hexagonal hollow bolts, diesel engine bolts, and oil line joint screws. These screws typically feature single, double, triple, quad, or even six holes to accommodate diverse connection requirements. They are typically made of carbon steel or stainless steel, offering excellent corrosion resistance and mechanical strength.

[0003] At present, hydraulic oil pipe screws often need to be quenched during the production process to improve their strength. However, after quenching, the surface of the hydraulic oil pipe screws will be stained with quenching coolant, resulting in a waste of quenching coolant and making the screws more prone to rust. Therefore, the utility model proposes a hydraulic oil pipe screw production quenching cooling device that is different from the prior art to solve the above technical problems. Utility Model Content

After quenching is completed, the driving component is started to drive the installation component and the screen frame to rotate synchronously. Under the action of centrifugal force, the quenching coolant attached to the surface of the hydraulic oil pipe screws is drained out through the screen frame.

Under the action of the second gear, the first gear can be driven to rotate in the opposite direction, and then the vertical shaft, the inclined rod and the screen frame can be driven to rotate synchronously. Under the action of centrifugal force, the quenching coolant attached to the surface of the hydraulic oil pipe screw is drained out through the screen frame.

[0019] In summary, the present invention has at least one of the following beneficial effects:

[0020] Starting the forward and reverse motors drives the rotating shaft and the second gear to rotate synchronously, thereby driving the first gear to rotate in the opposite direction, and then driving the installation vertical shaft, the installation inclined rod and the mesh frame to rotate synchronously.
