Description

Technical Field

[0001] This utility model relates to the field of steel ball cooling technology, and more specifically, to a steel ball cooling and quenching device. Background Technology

[0002] Steel balls are categorized by manufacturing process into ground steel balls, forged steel balls, and cast steel balls. They are also categorized by material into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, and alloy balls. During production, steel balls require quenching and cooling. Existing steel ball cooling and quenching devices are prone to damage from prolonged use in the ball-holding frames. Integrated designs result in high replacement costs, are inconvenient for disassembly and replacement, lack suitable quick-change mechanisms, and are susceptible to accidental movement of the steel balls after placement in the frames, leading to equipment or product damage. Furthermore, there is a lack of suitable safety limit mechanisms, and the drive motors used in these mechanisms are prone to damage from prolonged heat exposure. Finally, there is a lack of suitable drive adjustment mechanisms. Utility Model Content

[0005] The present invention is further configured such that each of the plurality of mounting rods is provided with a retaining ring corresponding to the mounting hole, thereby achieving initial positioning for installation.

[0006] The present invention is further configured such that a first connecting hole is provided on the locking plate, and a second connecting hole is provided at the front end of the support plate corresponding to the first connecting hole. The first connecting hole and the second connecting hole are connected by bolts to realize the locking operation.

[0007] The present invention is further configured such that a limiting ring is provided above the material frame, and L-shaped limiting rods are connected to both ends of the limiting ring. Limiting holes are provided on the support plate corresponding to the two L-shaped limiting rods. A limiting plate is connected to the upper end of the two L-shaped limiting rods. A threaded rod is rotatably provided on the upper surface of the support plate. A threaded hole is provided on the limiting plate corresponding to the threaded rod. The threaded rod and the threaded hole are threadedly connected to each other, which facilitates safe limiting after the steel ball is placed.

[0008] The present invention is further configured such that a fixing plate is provided on the rear side of the upper end face of the support plate, a drive motor is provided at the front end of the fixing plate, a drive rod is connected to the front end of the drive motor, and a transmission mechanism is provided between the drive rod and the threaded rod to achieve safe driving.

[0009] The present invention is further configured such that the transmission mechanism includes a first bevel gear and a second bevel gear, the first bevel gear is mounted on the drive rod, and the second bevel gear is mounted on the threaded rod, wherein the first bevel gear and the second bevel gear are meshed to ensure transmission effect.

[0010] The present invention is further configured such that a fixing hole is provided on the base plate, and multiple fixing holes are provided to achieve overall high-strength and stable locking.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a steel ball cooling and quenching device, which has the following beneficial effects: 1. The material frame design involves inserting the four corner mounting rods into the corresponding mounting holes on the support plate, where they are initially positioned by retaining rings. A locking rod, passing through the through hole and mounting hole, then engages with a locking plate for final fixation. This bolted connection ensures the stability of the material frame during vibration or movement. Furthermore, the entire material frame, including the mounting rods, can be easily removed and replaced simply by loosening the bolts and pulling out the locking rod. This convenient and quick operation allows for individual replacement of the material frame, reducing replacement costs.

[0012] 2. The design incorporates a limiting ring. This ring, positioned above the material frame, is connected to the limiting plate via L-shaped limiting rods on both sides that pass through limiting holes in the support plate. A threaded rod drives the limiting plate to raise and lower. When a steel ball is placed in the material frame, the limiting plate causes the limiting ring to press down smoothly, adhering tightly to the surface of the steel ball within the frame. This mechanical clamping and limiting mechanism effectively prevents accidental collisions between the steel ball and the overall equipment during quenching and cooling, significantly improving operational safety and the reliability of steel ball handling.

[0013] 3. Through the design of the drive motor, the drive motor and its transmission mechanism (drive rod, first bevel gear, second bevel gear) are arranged on the rear side of the upper surface of the support plate, rather than directly above the high-temperature quenching area. This layout keeps the critical power components away from the high-temperature steam, water mist, and heat radiation area generated by the quenching tank below the material frame. Power is transmitted from the horizontal drive rod to the vertical threaded rod via the bevel gear set, enabling drive operation from a safe position. This effectively avoids damage to the motor and transmission components caused by high-temperature and humid environments, significantly extends the equipment's service life, and reduces the risk of failure due to heat sources.

The first bevel gear 27 is installed on the drive rod 26, and the second bevel gear 28 is installed on the threaded rod 22. The first bevel gear 27 and the second bevel gear 28 are meshed.

[0027] Specifically, after the steel ball is initially placed into the corresponding material frame 9, the control device with its own control system starts the drive motor 25. The drive motor 25 drives the drive rod 26 to rotate. The first bevel gear 27 on the drive rod 26 and the second bevel gear 28 on the threaded rod 22 mesh to realize the rotation of the threaded rod 22. The threaded rod 22 and the threaded hole 23 of the limiting plate 21 are threaded together to realize the overall lifting and adjustment of the limiting plate 21, the L-shaped limiting rod 19 and the limiting ring 18.
