Description

Technical Field

[0001] This utility model relates to the field of ultra-high chromium alloy steel grinding ball processing technology, specifically to a quenching device for processing ultra-high chromium alloy steel grinding balls. Background Technology

[0002] The quenching device for processing ultra-high chromium alloy steel grinding balls refers to equipment used in heat treatment processes involving solution treatment or rapid cooling. Existing quenching devices generally lack a height adjustment structure, preventing arbitrary adjustment of the quenching height according to product specifications and reducing their flexibility in use. Furthermore, traditional quenching devices also lack a movable adjustment structure, making it impossible to flexibly adjust the quenching position of the ultra-high chromium alloy steel grinding balls.

[0003] In the prior art, Chinese patent document CN211897039U was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a quenching device for processing medium and high chromium copper grinding balls, including a box base, a sealed shell and a fixing rod; the quenching device for processing medium and high chromium copper grinding balls in this utility model has a quenching position adjustment structure, which allows it to perform lateral and longitudinal quenching position adjustment operations for high chromium copper grinding balls of different specifications, thereby improving its flexibility in use.

[0004] However, the above method will result in the high-temperature water vapor generated during quenching spreading everywhere, which will affect the surrounding environment of the processing and cause burns if it comes into contact with the human body. Utility Model Content

[0005] The purpose of this invention is to provide a quenching device for processing ultra-high chromium alloy steel grinding balls, so as to solve the problems mentioned in the background art.

[0030] The present invention will be further described in detail below with reference to embodiments:

[0031] Example 1

[0032] like Figures 1-6 As shown, this utility model provides a quenching device for machining ultra-high chromium alloy steel grinding balls, including a quenching box 1. An adjusting component 2 is provided on the surface of the quenching box 1. The adjusting component 2 includes two sets of electric actuators 21 (left and right). A limit frame 22 is fixedly installed on the top surface of the output rods of the two sets of electric actuators 21. A reduction motor 23 is fixedly installed on the right side of the limit frame 22. A lead screw 24 is fixedly installed at the output end of the reduction motor 23. The lead screw 24 is rotatably connected to the inner wall of the limit frame 22 via a bearing. Two sets of hanging ring rods 2 are threaded onto the surface of the lead screw 24. 5. The inner walls of both sets of hanging ring rods 25 are slidably connected to the surface of the middle rod of the limiting frame 22; a steam extraction component 3 is provided behind the quenching box 1, which includes a steam extraction unit and a filter unit; a rolling component 4 is provided on the top of the adjusting component 2, which includes a connecting unit and a rolling unit. By setting the steam extraction unit, the air extractor 31 can be started during quenching to work with the pipeline and the air guide hood 32 to absorb the scattered high-temperature water vapor, preventing a large amount of high-temperature water vapor from spreading around and affecting the surrounding environment and worker safety.

[0033] Example 2

[0034] like Figures 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the steam extraction unit includes a vacuum pump 31, which is fixedly installed on the back of the quenching box 1. A gas guide hood 32 is fixedly installed on the top surface of the quenching box 1. A groove 33 is opened on the bottom surface of the gas guide hood 32. The absorption pipe of the vacuum pump 31 is inserted into the gas guide hood 32. The exhaust pipe of the vacuum pump 31 is connected to a gas recovery device. The filtration unit includes two sets of filter plates 34. The sides of the two sets of filter plates 34 are fixedly connected to the inner wall of the gas guide hood 32. An activated carbon soft filter plate 35 is fixedly installed on the surface of the inner set of filter plates 34. By setting the filtration unit, water vapor can be filtered for solids under the action of the filter plates 34. At the same time, the activated carbon soft filter plate 35 can filter the water vapor for moisture and absorb the moisture it contains so that it can be recycled and reused under the action of the rolling part 4.

[0035] Example 3

[0036] like Figures 1-6As shown, based on embodiments 1-2, this utility model provides a technical solution: Preferably, the connecting unit includes an L-shaped telescopic rod 41, the L-shaped telescopic rod 41 includes an L-shaped inner rod threaded onto the surface of the lead screw 24, the inner wall of the L-shaped inner rod is slidably connected to the surface of the rod in the limiting frame 22, an outer rod is inserted and installed at the bottom of the L-shaped inner rod, the outer rod passes through the top of the air guide cover 32 vertically, and a spring 42 is fixedly installed on the surface of the outer rod. The rolling unit includes a mounting frame 43, and a compression spring 42 is fixedly installed vertically on the mounting frame 43. A limiting rod 45 is fixedly installed on the surface of the roller 44 and the mounting bracket 43. The rolling unit is set inside the air guide hood 32. The limiting rod 45 passes through the outer rod of the L-shaped telescopic rod 41 laterally and its surface is slidably connected to the inner surface of the L-shaped telescopic rod 41. By setting the rolling part 4, when the ultra-high chromium alloy steel grinding ball is quenched laterally, the extrusion roller 44 can move laterally along with it. Thus, under the action of the spring 42, the extrusion roller 44 can roll on the activated carbon soft filter plate 35, thereby squeezing out the water and returning it to the quenching box 1.

[0037] The working principle of the quenching device used for machining ultra-high chromium alloy steel grinding balls will be explained in detail below.

[0038] like Figures 1-6 As shown, this scheme uses a PLC as the core control component. The PLC is connected to the electric actuator 21, the geared motor 23, and the air extractor 31. When the quenching device is in use, the gas recovery equipment is connected through the air extractor 31 to introduce the processing water into the quenching box 1. The carrier containing the ultra-high chromium alloy steel grinding balls is hooked on the hanging ring rod 25. The PLC sends a descent command to the electric actuator 21, causing the limit frame 22 to move down and drive the carrier and ultra-high chromium alloy steel grinding balls into the water for quenching. At the same time, the PLC can also send a rotation command to the geared motor 23, causing the lead screw 24 to drive the hanging ring rod 25 to move laterally, thereby realizing the left and right movement of the carrier to promote the quenching efficiency of the ultra-high chromium alloy steel grinding balls.

[0039] During quenching, a strong absorption command can be sent to the vacuum pump 31 via PLC, allowing high-temperature steam to enter the air guide hood 32. Subsequently, the filter plate 34 and the activated carbon soft filter plate 35 can filter and remove moisture. Then, the gas can enter the gas recovery equipment through the vacuum pump 31.

[0040] When the lead screw 24 rotates, the L-shaped telescopic rod 41 moves laterally, so that the extrusion roller 44 can roll on the surface of the activated carbon soft filter plate 35 and squeeze it under the action of the spring 42, so that the filtered water can be squeezed out and discharged back into the quenching box 1 through the trough 33.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
