Description

Technical Field

[0001] The utility model relates to the technical field of quenching heat treatment, in particular to a steel ball quenching heat treatment device. Background Technique

[0002] In the process of steel ball processing, it is necessary to perform quenching treatment on the steel balls. The steel balls are placed in a heating furnace for carburizing treatment to form a carburized layer on the surface of the steel balls. Then, the steel balls are put into a tempering furnace for tempering to eliminate the brittleness of the carburized layer and improve the strength and toughness of the steel balls. Finally, the temperature of the steel balls is reduced by putting the steel balls into a quenching bath or salt water to complete the quenching process.

[0003] When the steel balls are put into the quenching liquid, since a carburized layer will be formed on the surface of the steel balls, when entering the quenching liquid or salt water, the carburized layer on the surface of the steel balls will condense into some black slag and break away from the surface of the steel balls. Over time, some black carburized slag will accumulate at the bottom of the cooling tank, and it will be inconvenient to clean when cleaning the cooling tank because the carburized slag precipitates at the bottom. Content of the Utility Model

[0004] The purpose of the utility model is to provide a steel ball quenching heat treatment device to solve the problem that some black carburized slag will accumulate at the bottom of the cooling tank and it will be inconvenient to clean when cleaning the cooling tank as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A steel ball quenching heat treatment device, the quenching heat treatment device includes a device main body, a cavity filtering structure and a connection structure. The cavity is opened inside the device main body. The filtering structure is movably disassembled at the bottom end of the device main body. The connection structure is fixedly arranged at four corner positions of the bottom wall of the cavity. The connection structure includes a fixed block fixedly arranged on the surface of the cavity, a telescopic rod fixedly arranged on the top surface of the fixed block, a torsion spring wound around the outer surface of the telescopic rod, a rotating plate fixedly arranged at the top end of the telescopic rod, and a docking block slidably connected to the fixed wall of the rotating plate. The top end of the docking block contacts the bottom wall of the filtering structure.

[0006] Optionally, the connection structure further includes a connection block fixedly arranged at one end of the torsion spring and a rectangular notch opened at the bottom of the connection block. The outer side wall of the connection block is fixedly connected to the bottom end of the docking block.

[0007] Optionally, the filtering structure includes a filter plate detachably arranged inside the device main body, leakage holes opened on the surface of the filter plate, and sliding circular discs fixedly arranged at the middle positions on both sides of the filter plate.

[0008] Optionally, the filtering structure further includes installation round holes opened at four corner positions of the filter plate. The inner side of the installation round holes abuts against the top end of the docking block.

[0009] Optionally, the quenching heat treatment equipment also includes a load-bearing plate fixed at the bottom end of one side of the device body, a combustion pump fixed at the top of the load-bearing plate, a tempering frame arranged at the top of the combustion pump, and a through net fixed on the bottom wall of the tempering frame, and a control panel is arranged on the outside of the device body.

[0010] Optionally, calibration bars are fixedly provided on both sides of the interior of the device body, a through groove is provided on the side wall of the calibration bar, and the calibration bar is slidably connected to the sliding disc.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

When the inner side of the device main body is precipitated due to carbonization, the precipitate can be deposited and accumulated on the outer surface of the filter structure. In this way, only the filter structure needs to be cleaned to clean the bottom wall of the device main body. At the same time, the filter structure is convenient to disassemble on the inner side of the device main body, so that the inner bottom wall of the device main body is easy to clean.

The cavity 4 is opened inside the device body 1, and the filtering structure 3 is movably disassembled at the bottom end of the device body 1. The connecting structure 10 is fixed at the four corners of the bottom wall of the cavity 4. The connecting structure 10 includes a fixed block 105 fixed on the surface of the cavity 4, a telescopic rod 104 fixed on the top surface of the fixed block 105, a torsion spring 103 wound on the outer surface of the telescopic rod 104, a rotating plate 101 fixed on the top of the telescopic rod 104, and a docking block 102 slidably connected to the fixed wall of the rotating plate 101. The top of the docking block 102 is connected to the bottom wall of the filtering structure 3. The connection structure 10 also includes a connection block 106 fixedly arranged at one end of the torsion spring 103 and a rectangular notch 107 opened at the bottom of the connection block 106. The outer wall of the connection block 106 is fixedly connected to the bottom end of the docking block 102. It can be further explained that during the assembly of the filtering structure 3, the torsion spring 103 wrapped around the outer side of the telescopic rod 104 is in a rotating state. The torsion spring 103 rotates around the telescopic rod 104 as the center of the circle, and drives the connection block 106 to rotate around the rotating plate 101 as the center of the circle during rotation. At this time, the connection block 106 drives the docking block 102 to slide on the side wall of the rotating plate 101, and docks with the four corner positions of the filtering structure 3 during the sliding process to complete the position limitation of the filtering structure 3.

[0033] The filter structure 3 includes a filter plate 31 that can be removed from the inner side of the device body 1, a leakage hole 32 opened on the surface of the filter plate 31, and a sliding disc 33 fixedly arranged at the middle position on both sides of the filter plate 31.

A through groove is arranged on the side wall of the calibration strip 2. The calibration strip 2 is slidably connected with the sliding disc 33. When the filtering structure 3 is initially assembled, the sliding disc 33 is allowed to fall from top to bottom along the through groove arranged on the side wall of the calibration strip 2 to the bottom of the device body 1.

[0035] Working principle: When the filter structure 3 is initially assembled, the sliding disc 33 is allowed to fall from top to bottom along a through groove provided on the side wall of the calibration strip 2 to the bottom of the device body 1. During the assembly of the filter structure 3, the torsion spring 103 wrapped around the outer side of the telescopic rod 104 is first in a rotating state, and the torsion spring 103 rotates around the telescopic rod 104 as the center of the circle, and drives the connecting block 106 to rotate around the rotating plate 101 as the center of the circle during the rotation. At this time, the connecting block 106 drives the docking block 102 to slide on the side wall of the rotating plate 101, and docks with the four corner positions of the filter structure 3 during the sliding process to complete the position limitation of the filter structure 3. The complete filter structure 3 is assembled on the inner side of the device body 1, and then the filter plate 31 and the leakage hole 32 opened on the filter plate 31 are used to filter the carbonized impurities, so as to facilitate the cleaning of the bottom end of the device body 1. The inner side of the device body 1 is filled with quenching liquid or brine, and the tempered steel ball is placed in the quenching liquid or brine inside the device body 1 to complete the cooling.
