Description

Technical Field

[0001] This utility model relates to the field of steel ball processing, and in particular to a steel ball cooling device that can ensure uniform cooling. Background Technology

[0002] After heat treatment, steel balls need to be poured into water for rapid and uniform cooling. Existing devices use a receiving hopper placed in the water, where the balls directly enter after falling in. However, the steel balls move vertically after falling into the water, and the straight-line distance from the water surface to the bottom of the receiving hopper is relatively short. This means that after a steel ball enters the hopper and stops moving, subsequent steel balls may not be fully cooled before merging with the preceding ones. This prevents the steel balls from cooling completely in a short time, or only achieves partial cooling, affecting their hardness and wear resistance. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a steel ball cooling device that can ensure uniform cooling. By dispersing the steel ball and extending the path of the steel ball in the water, the steel ball is cooled uniformly, thus ensuring the hardness of the steel ball.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A steel ball cooling device that ensures uniform cooling includes a support frame placed in water, a hopper installed on one side of the support frame, a ball flow channel fixed at the discharge port at the lower end of the hopper, and a ball collection box placed on the other side of the support frame.

[0006] The hopper is equipped with an inverted conical slope, which is fixed in the hopper by a support rod. An annular channel is reserved between the inner wall of the hopper and the edge of the inverted conical slope.

[0007] The central axis of the inverted conical slope coincides with the central axis of the hopper.

[0008] The ball-holding box includes a box body, with a hanging ring at the top of the box body that extends above the water surface; and an opening on one side of the bottom of the box body, with a vertically slidable pull-out plate at the opening.

[0009] An inclined plate is installed inside the box, with the inclined plate lower on the side facing the pull-out plate, and the lower end of the inclined plate in contact with the bottom of the box.

[0010] The cross-section of the flow channel is U-shaped.

[0011] The support frame, hopper, ball flow channel, and ball collection box are all made of stainless steel.

[0012] This invention provides a steel ball cooling device that ensures uniform cooling, with the following technical effects: By setting up a hopper with an inverted conical slope, the steel balls can be dispersed after entering the water, and the vertical movement of the steel balls can be changed to an inclined movement. After passing through the annular channel, the steel balls enter the inclined ball flow channel and finally fall vertically into the ball collection box. Compared with the traditional method of directly pouring the steel balls into the water and letting them fall into the collection box, this device changes the straight trajectory of the steel balls into a broken line and changes the closed state of the steel balls into a dispersed state, thereby extending the trajectory and breaking up the steel balls, so that the steel balls can fully contact the water and the contact time is extended.

[0018] like Figure 1-3 As shown, a steel ball cooling device that ensures uniform cooling includes a support 1. A hopper 2 is fixed to one side of the support 1. The hopper 2 has an inverted conical slope 3 inside, which is fixed in the hopper 2 by a support rod 4. An annular channel 5 is reserved between the edge of the inverted conical slope 3 and the side wall of the hopper 2. The bottom side of the hopper 2 is connected to a ball flow channel 6, and the other side of the ball flow channel 6 points downward toward the other side of the support 1. A ball holding box 7 is placed at the lower part of the other side of the support 1, and the outlet of the ball flow channel 6 points toward the upper opening of the ball holding box 7.

[0019] The ball-holding box 7 includes a box body 7.1, with a lifting ring 7.2 on the upper part of the box body 7.1. An opening is located on one side of the bottom of the box body 7.1, and a slide rail 7.3 is provided on the outer side of the opening. A pull-out plate 7.4 is slidably disposed within the slide rail 7.3. The opening of the box body 7.1 can be opened when the box is moved upwards, facilitating the removal of the steel balls.

[0020] Preferably, a sloping plate 7.5 is installed inside the housing 7.1. The side of the sloping plate 7.5 facing the pull-out plate 7.4 is lower, and the bottom end of the sloping plate 7.5 contacts the bottom of the housing 7.1. The other side of the sloping plate 7.5 away from the pull-out plate 7.4 is higher.

[0021] Preferably, the flow channel 6 has a U-shaped cross-section, including left and right side plates and a bottom plate. Since this device is placed in water, setting the flow channel 6 as an open structure allows for faster heat exchange with the external water flow.

[0022] Working principle and process:

[0023] This device is placed in a water tank. After the steel balls in the furnace are heat-treated, they are continuously discharged into the water through the feed inlet. The steel balls falling into the water gradually enter the feed hopper 2, are dispersed by the inverted conical slope 3, and then enter the ball flow channel 6 through the annular channel 5. After flowing through the ball flow channel 6, they enter the ball collection box 7. Because the steel balls pass through the inclined conical slope and the inclined ball flow channel 6 before finally reaching the ball collection box 7, the entire process involves a longer journey of the steel balls in the water, resulting in a longer cooling time. At the same time, the conical slope also disperses the steel balls, which is beneficial for each individual steel ball to fully contact the water and cool completely and evenly within a certain period of the feeding process, ensuring hardness.
