Description

Technical Field

[0001] This utility model relates to the production of steel balls, and in particular to a steel ball quenching device. Background Technology

[0002] In existing steel ball production processes, steel ball quenching equipment is required for quenching. Some existing steel ball quenching equipment includes a base and a collection box. The base is equipped with a quenching pool filled with quenching fluid, and the collection box is placed inside the quenching pool. In the steel ball production process, the previous step directly pours the steel balls into the collection box of the quenching pool, and then waits for a period of time for quenching. However, this direct pouring method results in insufficient movement time and distance of the steel balls within the quenching pool, easily leading to uneven quenching; the steel balls accumulate rapidly in the collection box without sufficient cooling, making it difficult for the internal steel balls to dissipate heat, and causing the temperature of the quenching fluid near the collection box to become too high, affecting the quenching effect of the steel balls.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Reference Figures 1 to 3 This invention relates to a steel ball quenching device, comprising a base 100, a ball guiding mechanism 200, and a collection box 300. The base 100 has a quenching pool 110 with its opening facing upwards. The ball guiding mechanism 200 is located on the base 100 and includes a guide frame 210 with a guide channel 211 located within the quenching pool 110. The guide channel 211 is inclined downwards along its length, and its lower end has a ball outlet 212. The collection box 300 is located on the base 100, allowing balls within the guide channel 211 to enter the collection box 300 through the ball outlet 212.

[0031] When the steel ball quenching device is working, the previous process sends the steel ball into the guide groove 211. The guide groove 211 is inclined downward along its length, allowing the steel ball to roll along the guide groove 211 under the action of gravity, and finally the steel ball enters the collection box 300. Since the guide groove 211 is located inside the quenching pool 110, the steel ball can roll a longer distance in the quenching pool 110, increasing the movement time and distance of the steel ball in the quenching pool 110, thereby improving the quenching uniformity. Furthermore, the steel ball dissipates heat more fully before entering the collection box 300, making it easier to disperse the heat to all parts of the quenching pool 110, avoiding the risk of the quenching liquid temperature being too high near the collection box 300, and improving the quenching effect.

[0032] In this embodiment, the sphere guiding mechanism 200 further includes a receiving tray 220, which is provided with a receiving groove 221. The receiving groove 221 is inclined downward along the length direction, and the width of the receiving groove 221 tends to decrease downward along the length direction. The lower end of the receiving groove 221 is provided with a discharge port 222, which is connected to the ball inlet of the guiding groove 211. The receiving tray 220 is provided with an opening facing upward.

[0033] A receiving tray 220 is provided, into which steel balls from the previous process can be poured. Since the receiving groove 221 of the receiving tray 220 is inclined downward along its length and has a narrowing tendency, when steel balls are poured in batches, the steel balls can gradually enter the ball inlet of the guide groove 211 in a queue from the narrower discharge port 222. This facilitates rapid material discharge from the previous process without affecting the quenching effect of the steel balls. It eliminates the need for the previous process to slowly discharge the steel balls into the guide groove 211, thereby improving the efficiency of steel ball transfer between processes.

[0034] In this embodiment, the receiving groove 221 and the guide groove 211 are arranged at an angle, with the receiving groove 221 located on one side of the guide groove 211 along the width direction. This is beneficial for making full use of the space in the quenching pool 110 for layout, making the structure of the steel ball quenching device more compact. It can also reduce the rolling speed of the steel ball when it enters the guide groove 211 from the receiving groove 221, which is beneficial for increasing the rolling time of the steel ball and improving the quenching uniformity and quenching effect.

[0035] Specifically, the receiving trough 221 is arranged inclined downwards in the front-to-back direction, and the guide trough 211 is arranged inclined downwards in the left-to-right direction.

[0036] In this embodiment, the receiving tray 220 is located inside the quenching pool 110, so that when the steel ball is in the receiving groove 221, it can also be immersed in the quenching liquid and undergo a certain degree of quenching, thereby improving the quenching effect of the steel ball.

[0037] Specifically, in this embodiment, the guide channel 211 is a structure formed by bending a plate, which has lower material costs and better processability. The receiving tray 220 is a structure formed by bending a plate, which has higher material costs but better processability.

[0038] Generally, lower quenching temperatures result in better quenching of steel balls, allowing them to form a more suitable metallographic structure. Therefore, the following improvements were made:

[0039] In this embodiment, a liquid conveying component 400 is also included. The liquid conveying component 400 is disposed on the base 100. The liquid conveying component 400 includes a pump body 410, a suction pipe 420, and a discharge pipe 430. One end of the suction pipe 420 is connected to the inlet of the pump body 410, and the other end of the suction pipe 420 is connected to the quenching tank 110. One end of the discharge pipe 430 is connected to the outlet of the pump body 410. The discharge pipe 430 is provided with a discharge port, which is opposite to and connected to the receiving trough 221, and opposite to and connected to the guide trough 211.

[0040] When the steel ball quenching device is working, the liquid transport component 400 can be started. The pump body 410 draws quenching liquid from the colder part of the quenching pool 110 through the suction pipe 420, and transports the colder quenching liquid to the receiving tank 221 and the guide tank 211 through the discharge pipe 430, thereby reducing the temperature of the quenching liquid at the receiving tank 221 and the guide tank 211, thereby improving the quenching effect and quenching stability.

[0041] In this embodiment, the discharge port 222 of the receiving trough 221 is located at the middle of the guide trough 211 along its length, and the liquid outlet pipe 430 is provided with a first liquid outlet 431, which is connected to the upper end of the guide trough 211. The liquid outlet pipe 430 delivers low-temperature quenching liquid into the guide trough 211 through the first liquid outlet 431, which helps to keep the quenching liquid in the guide trough 211 at a relatively low temperature.

[0042] In this embodiment, the liquid outlet pipe 430 is provided with a second liquid outlet 432, which is connected to the upper end of the receiving tank 221. The liquid outlet pipe 430 delivers low-temperature quenching liquid into the receiving tank 221 through the second liquid outlet 432, which helps to keep the quenching liquid in the receiving tank 221 at a relatively low temperature.

[0043] Specifically, the other end of the suction pipe 420 can be connected to several points in the quenching pool 110 to better absorb the colder quenching liquid.

[0044] It is understood that in other embodiments, the liquid outlet pipe 430 may also be connected to one of the receiving tank 221 or the guide tank 211 through the liquid outlet.

[0045] In this embodiment, a control module and a temperature sensor are also included. The temperature sensor is disposed on the base 100 and located in the quenching tank 110. The temperature sensor is electrically connected to the control module, and the control module is electrically connected to the pump body 410.

[0046] The temperature sensor can detect the temperature of the quenching liquid at the receiving tank 221, the guide tank 211, or the collection box 300. The control module can control the opening and closing of the pump body 410 or the speed at which the pump body 410 delivers the quenching liquid based on the temperature of the quenching liquid, thereby improving the flexibility of the steel ball quenching equipment and saving energy.

[0047] Specifically, the control module can adopt structures such as microcomputers, single-chip microcomputers, or circuit boards with control circuits.

[0048] In this embodiment, the collection box 300 is provided with a collection trough 310 with the opening facing upwards. The collection box 300 can be raised and lowered and can enter or leave the quenching pool 110. The guide frame 210 includes a frame body 213 and an adjusting member 214. The ball guiding mechanism 200 also includes an adjusting drive member 230. The guide trough 211 includes an upper trough section and a lower trough section. The upper trough section is located in the frame body 213, and the lower trough section is located in the adjusting member 214. The lower end of the upper trough section is connected to the upper end of the lower trough section. The ball outlet 212 is located in the lower trough section, and the ball inlet is located in the upper trough section. The adjusting member 214 is rotatably mounted on the frame body 213 and can be rotated to a clearance position and a ball outlet position. In the clearance position, the guide frame 210 and the collection box 300 are horizontally offset. In the ball outlet position, the ball outlet 212 is located above the collection trough 310. The adjusting drive member 230 is connected to the adjusting member 214 and is used to drive the adjusting member 214 to rotate.

[0049] After the collecting box 300 is full of steel balls, it can rise and detach from the quenching tank 110 to facilitate the retrieval of quenched steel balls in the next process. The empty collecting box 300 can then be lowered back into the quenching tank 110 to continue collecting steel balls. The lower end of the guide frame 210 has a rotatable adjusting member 214. When the collecting box 300 is placed in the quenching tank 110, the adjusting member 214 can rotate to the ball-discharging position. At this time, the adjusting member 214 is above the collecting box 300, allowing the steel balls to fall stably into the collecting box 300. When the collecting box 300 needs to rise, the adjusting member 230 can drive the adjusting member 214 to rotate, avoiding the upward track of the collecting box 300, thus facilitating its ascent. The aforementioned guide frame 210 makes the steel ball quenching device more compact and allows the steel balls to enter the collecting box 300 more stably.

[0050] In this embodiment, the adjusting drive component 230 is a pull rod, one end of which is pivotally connected to the adjusting component 214, and the pull rod extends upward. By pulling the adjusting component 214 with the pull rod, the adjusting component 214 rotates. The driving structure is relatively simple and easy to implement.

[0051] Specifically, the lower end of the pull rod has a hook, and the adjusting member 214 has a through hole. The hook engages with the through hole, making the two pivotally connected. It is conceivable that in some other embodiments, the two could also be pivotally connected via a pivot.

[0052] Specifically, the lever can be pulled manually by the operator, or it can be pulled by a cylinder, electric cylinder, or hydraulic cylinder, etc. Those skilled in the art can choose appropriately according to actual needs.

[0053] It is conceivable that in other embodiments, the adjusting drive 230 may also be other structures, such as a pull rope, used in conjunction with a winch, etc., and those skilled in the art can make reasonable choices according to actual needs.

[0054] Specifically, the base 100 is provided with four guide rails 120 in the quenching pool 110. The guide rails 120 extend vertically, and the four sides of the collection box 300 are slidably connected to the four guide rails 120, so that the collection box 300 can move up and down along a fixed trajectory, with good stability.

[0055] Specifically, the steel ball quenching device is also equipped with a cover 500, which is detachably installed over the upper opening of the quenching pool 110. This prevents the quenching liquid from evaporating or splashing during conventional quenching, making it safer and more environmentally friendly. When it is necessary to remove the collection box 300, the cover 500 can be opened to facilitate its removal.

[0056] Specifically, the quenching fluid in the quenching pool 110 can be water or oil, etc., and those skilled in the art can make a reasonable selection according to actual needs.
