Description

Technical Field

[0001] The invention belongs to the field of quenching equipment, and in particular relates to a wear-resistant steel ball impurity removal quenching device. Background Art

[0002] Wear-resistant steel balls need to be quenched and tempered at a certain temperature to improve their strength, hardness, wear resistance, fatigue strength and toughness. The temperature of the quenching liquid and the uniformity of the temperature distribution have a great influence on the quenching effect of the wear-resistant steel balls. If the temperature of the quenching liquid is too high, the cooling rate will be significantly reduced and the quenching effect cannot be achieved. It is very necessary to use cooling equipment to cool the quenching liquid. At present, green silicon carbide uses wet ball milling to grind the coarse material into fine material by grinding steel balls. The most important link in the production of grinding steel balls is quenching. The quality of quenching determines the quality of the steel balls. The temperature of the water in the sink will rise after a period of use, which will cause the steel balls to be more brittle and less tough, thus affecting the grinding effect. Therefore, the sink will cooperate with the heat dissipation system. However, in actual use, the iron filings that fall from the steel balls are mixed in the water, and these iron filings will enter the heat dissipation system, causing damage to the heat dissipation system.

[0003] The utility model "A steel ball quenching device for silicon carbide production with impurity removal" with patent number CN214218809U includes a water tank, a feed pipe, a material conveying mechanism, a bracket assembly, a discharge channel, a drive device, a water pump assembly and a heat dissipation assembly; the bracket assembly is connected to the side of the water tank, and the drive device is arranged on the bracket assembly; the material conveying mechanism is inclined and the surface is water-permeable, the bottom end of the material conveying mechanism is rotatably connected to the water tank, and the drive device is driven and connected to the top of the material conveying mechanism; the feed pipe is fixed to the inner wall of the water tank and the bottom end leads to the feed end of the material conveying mechanism, and the discharge channel is connected to the bracket assembly at the discharge end of the material conveying mechanism; the water pump assembly is connected to the water tank through a water suction pipe, and the heat dissipation assembly is connected to the water pump assembly through a water inlet pipe; and also includes an impurity removal mechanism arranged between the water pump assembly and the water tank. The utility model can remove iron filings or other impurities mixed in the water tank, thereby effectively protecting the heat dissipation system.

[0004] The above scheme adds a filter at the liquid outlet of the cylinder to remove impurities other than iron filings and further protect the heat dissipation system. However, after the steel ball is quenched, the iron filings first enter the quenching liquid. The iron filings have a certain weight, and some of the iron filings are difficult to enter the cylinder. They exist in the quenching liquid, which still affects the quenching effect. For this reason, we propose a wear-resistant steel ball impurity removal quenching device. Summary of the invention

[0005] The purpose of the present invention is to provide a wear-resistant steel ball impurity removal and quenching device, which can effectively solve the problem in the existing quenching device proposed in the background technology that after the steel ball is quenched, the iron chips first enter the quenching liquid. The iron chips have a certain weight, and some of the iron chips are difficult to enter the cylinder. They exist in the quenching liquid, which still affects the quenching effect.

[0013] Preferably, the quenching part includes a quenching frame fixed to the bottom of a fixed frame, a box cover hinged to the top of the quenching frame, a screen embedded in the quenching frame, and a sealing door arranged on one side of the quenching frame, wherein the sealing door is located below the screen, and the quenching frame is located in the quenching chamber.

[0014] Preferably, the quenching part also includes a feed pipe fixedly arranged at the bottom of the quenching frame and a third solenoid valve arranged at one side of the feed pipe. The bottom wall of the inner cavity of the quenching frame is inclined, and the interior of the feed pipe is connected with the interior of the quenching frame.

[0015] Preferably, the debris collecting member comprises a connecting frame movably arranged at the bottom of the quenching frame, and a mounting plate is fixedly arranged on the outer side of the connecting frame.

[0016] Preferably, the top of the mounting plate is located outside the quenching frame, and a screw rod is provided on the outside of the mounting plate, and one end of the screw rod passes through the mounting plate and extends into the quenching frame.

[0017] Preferably, the sundries collecting component further comprises a filter screen movably arranged in the connecting frame, and a placement rack fixedly arranged on the top of the filter screen, a placement slot adapted to the placement rack is opened on the top of the connecting frame, and the placement rack is movably arranged in the placement slot.

A waste discharge pipe is fixedly provided at the bottom of the connection frame, and a fourth electromagnetic valve is provided on one side of the waste discharge pipe.

[0019] The present invention has the following beneficial effects:

[0020] 1. The present invention introduces quenching liquid into the quenching box, opens the box cover, puts a plurality of steel balls into the quenching frame, drives the piston rod downward through the hydraulic cylinder, thereby drives the fixing frame and the quenching part to move downward, so that the quenching frame is in the quenching liquid, and the quenching liquid enters the quenching frame through the screen. The steel balls contact the quenching liquid, and the iron filings generated on the surface of the steel balls fall off. Under the action of the gravity of the iron filings, the iron filings move downward. Since the bottom wall of the inner cavity of the quenching frame is inclined, the iron filings all fall into the feeding pipe, thereby reducing the impact of the iron filings on the quenching box. The quenching liquid is contaminated. When quenching, the temperature of the quenching liquid continues to rise. A first liquid pump is provided on one side of the output pipe, and a second liquid pump is provided on one side of the input pipe. By starting the second liquid pump, the quenching liquid in the quenching box is sucked into the refrigeration box, and its heat is absorbed to the outside of the refrigeration box through the refrigeration plate, thereby cooling the liquid in the refrigeration box. After cooling, the first liquid pump is started to transfer the cooled quenching liquid in the refrigeration box to the quenching box. The circulation unit continues to work, thereby continuously ensuring the temperature range of the quenching liquid in the quenching box.

[0021] 2. The present invention provides a debris collection piece so that all iron filings fall into the feed pipe, the third solenoid valve is opened, and the electromagnetic rod is started, so that the iron filings in the feed pipe fall on the filter screen. The electromagnetic rod has a downward adsorption force on the iron filings, so that when the quenching frame shakes up and down, the iron filings are difficult to surge upward. The hydraulic cylinder drives the piston rod, the supporting frame, the fixing frame and the quenching frame to move up and down, thereby improving the quenching effect of the steel ball. After the quenching is completed, the fixing frame, the quenching frame and the debris collection piece are driven by the hydraulic cylinder to move upward to the top of the quenching box, and then the fourth solenoid valve is opened, and the quenching liquid in the quenching frame and the connecting frame is discharged from the waste pipe into the quenching box, the sealing door is opened, the steel ball is taken out, and then the screw is removed, the connecting frame is removed from the quenching frame, the electromagnetic rod is closed, the filter screen is taken out upward, the iron filings are processed, and the quenching and debris removal of the wear-resistant steel balls are completed, and the debris removal effect is good.
