Description

Technical Field

[0001] This utility model relates to the technical field of steel ball quenching equipment, and in particular to an oil tank for steel ball quenching with a lifting function. Background Technology

[0002] To improve the hardness and wear resistance of steel balls, heat treatment is required during the manufacturing process. Conventional heat treatment consists of two parts: quenching and tempering. These methods achieve the required mechanical properties of the steel, such as hardness and toughness. Quenching refers to the process where the workpiece is heated in a furnace to a temperature above its phase transformation temperature and held for a certain time, causing a transformation in the material's microstructure. It is then rapidly cooled in a coolant to obtain martensite.

[0003] Because a large number of steel balls are poured into the cooling medium during industrial production, prolonged use can lead to localized oil temperature changes, resulting in poor quenching and cooling uniformity of the steel balls, which in turn leads to poor uniformity of hardness. Utility Model Content

[0004] To address the aforementioned technical problems, an oil tank with lifting function for quenching steel balls is provided.

[0005] To achieve the above objectives, this utility model discloses an oil tank for quenching steel balls with a lifting function, including a main furnace foundation and an oil tank set inside the main furnace foundation. A leveled concrete foundation is set on one side of the top of the main furnace foundation, and a periodic furnace body is installed on the top of the concrete foundation. The periodic furnace body is offset towards one side of the oil tank. A discharge port located inside the oil tank is set below the discharge port of the periodic furnace body. An inclined lifting component is installed in the oil tank on the side of the discharge port. A discharge component is set at a position above the oil tank of the lifting component. A temperature control system is set inside the oil tank.

[0006] Furthermore, the lifting assembly includes an inclined lifting frame, a pulley frame is installed on the top of the lifting frame, a winch is welded and fixed to the top of the oil tank, and the output end of the winch is provided with a cable that passes around the pulley frame and is connected to the lifting bucket. The lowest point of the lifting assembly is located directly below the material discharge port.

[0007] Furthermore, the lifting bucket includes a lifting bucket body and lifting handles movably installed on both sides of the lifting bucket body. A pulley is installed on the side of the lifting handle away from the lifting bucket body, and a cable is connected to the pulley. Rollers are installed at the bottom of the lifting bucket body.

[0008] Furthermore, the main body of the lifting bucket is a trapezoidal open barrel structure formed by welding bent parts, and a number of rectangular through slots arranged in an array are opened on the end face of the main body of the lifting bucket near the lifting frame and perpendicular to the lifting frame.

[0009] Furthermore, the discharge port is welded and fixed to the side wall of the oil tank by channel steel. The discharge port includes two sliding plates close to the side wall of the oil tank and a side plate opposite to the sliding plates. Both the sliding plates and the side plates are made of bent steel plates with a bending angle of 135°. The inclined edges of the two sliding plates are parallel to each other, and the inclined edges of the sliding plates and the inclined edges of the side plates are perpendicular to each other. The lower sliding plate points to the opening at the lowest point of the lifting bucket body.

[0010] Furthermore, the discharge assembly includes a notch located on the lifting frame above the oil tank cover, a discharge slide plate is installed on the side of the notch away from the main body of the lifting bucket, and a collection hopper is provided below the discharge slide plate.

[0011] Furthermore, the temperature control system includes a heater frame installed on the top of the oil tank. The heater frame is fixed to the inner wall of the oil tank by welding steel plates. Several equally spaced heating tubes are installed at the bottom of the steel plates, and the heating tubes are installed below the liquid surface.

[0012] Furthermore, the temperature control system includes oil circulation pumps installed on both sides of the oil tank. The oil circulation pumps are connected to both sides of the discharge port through pipelines. A plate heat exchanger is installed between one set of oil circulation pumps and the pipelines, and extends to the bottom of the oil tank through the pipelines.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, a leveled concrete foundation 3 is provided on one side of the top of the main furnace foundation 1. An oil trough pit for fixing the oil trough is provided inside the main furnace foundation. The bottom is a concrete pad, and the side walls are brick structures. The ground and the inner walls of the pit are smoothed with cement mortar. The oil trough includes an oil trough frame and an oil trough cover set on top of the oil trough frame. The oil trough frame is fixed by welding. Galvanized plates are riveted to the edges of the oil trough, and mineral wool insulation material is filled inside the galvanized plates to improve the insulation performance of the main furnace foundation. A periodic furnace body 4 is installed on top of the concrete foundation 3, facing the oil trough 2. With one side offset, a discharge port 5 is set below the discharge port of the periodic furnace body 4, located in the oil tank 2. An inclined lifting component 6 is installed in the oil tank 2 on the side of the discharge port 5. A discharge component is set at a position of the lifting component 6 above the oil tank 2. A temperature control system is set in the oil tank 2. By increasing the height of the oil tank and extending the length of the lifting frame, the time that the steel ball spends in the oil tank is increased, ensuring that the surface of the steel ball is in full contact with the cooling oil. The temperature control system in the oil tank monitors the oil temperature in real time to ensure that the oil temperature is uniform throughout the oil tank, avoid affecting the quenching effect, and improve product quality.

[0024] The lifting assembly 6 includes an inclined lifting frame 61, with a pulley frame 62 mounted on the top of the lifting frame 61. A winch 63 is welded and fixed to the top of the oil tank 2. The output end of the winch 63 is provided with a cable that passes around the pulley frame 62 and is connected to the lifting bucket 64. The lowest point of the lifting assembly 6 is located directly below the discharge port 5. The lifting bucket 64 includes a lifting bucket body 641 and lifting handles 642 movably mounted on both sides of the lifting bucket body 641. A pulley is mounted on the side of the lifting handle 642 away from the lifting bucket body 641, and a cable is connected to the pulley. Rollers are mounted on the bottom of the lifting bucket body 641. The winch, as the driving structure, pulls the lifting handle through the cable. The lifting handle drives the rollers at the bottom of the lifting bucket body to rise along the lifting frame, ensuring that all surfaces of the steel balls are in full contact with the cooling oil.

[0025] The main body 641 of the lifting bucket is a trapezoidal open barrel structure made of bent parts welded together. Several rectangular through grooves are arranged in an array on the end face of the main body 641 near the lifting frame 61 and perpendicular to the lifting frame 61. The steel balls fall from the hopper and enter the main body of the lifting bucket through the opening, which prevents the steel balls from scattering and ensures concentration. After the lifting bucket leaves the oil tank, the cooling oil inside the main body of the lifting bucket flows out to the oil tank through the through grooves to achieve solid-liquid separation and prevent it from entering the collection hopper with the steel balls.

[0026] The discharge port 5 is fixed to the side wall of the oil tank 2 by welding channel steel. The discharge port 5 includes two sliding plates 51 close to the side wall of the oil tank 2 and a side plate 52 opposite to the sliding plates 51. Both the sliding plates 51 and the side plate 52 are made of steel plates bent at a bending angle of 135°. The inclined sides of the two sliding plates 51 are parallel to each other, and the inclined sides of the sliding plates 51 and the side plates 52 are perpendicular to each other. The lower sliding plate 51 points to the opening at the lowest point of the lifting bucket body 641. After the discharge port of the periodic furnace rotates, the steel balls are guided into the discharge port. The steel balls pass through the upper sliding plate, the side plate and the lower sliding plate in sequence and fall into the lifting bucket body located at the lowest point of the lifting frame.

[0027] The discharge assembly includes a notch located on the lifting frame 61 above the oil tank cover. A discharge slide plate 7 is installed on the side of the notch away from the lifting bucket body 641. A collection hopper 8 is located below the discharge slide plate 7. After the cooling oil drains out of the lifting bucket body, the lifting bucket body rotates around the bottom roller. Due to the steel balls loaded inside, the lifting bucket body rotates around the roller under its own weight. The opening of the lifting bucket body tilts onto the discharge slide plate, pouring the steel balls inside into the collection hopper.

[0028] The temperature control system includes a heater frame 9 installed on the top of the oil tank 2. The heater frame 9 is welded and fixed to the inner wall of the oil tank 2 by a steel plate 91. Several equally spaced heating tubes 92 are installed at the bottom of the steel plate 91. The heating tubes 92 are installed below the liquid surface. Angle steel frames are connected to the side of the steel plate and screws are connected at the top for easy disassembly and maintenance. The heating tubes adopt a U-shaped tube structure and are installed below the liquid surface to ensure electrical safety and prevent the heating position of the heating tubes from being higher than the liquid surface, otherwise it may cause a fire.

[0029] The temperature control system includes oil circulation pumps 93 installed on both sides of the oil tank 2. The oil circulation pumps 93 are connected to both sides of the discharge port 5 through pipelines. One set of oil circulation pumps 93 is equipped with a plate heat exchanger 94 between it and the pipeline, and extends to the bottom of the oil tank 2 through the pipeline. The temperature control system also includes a PLC-controlled temperature controller 95. The PLC controls the start-up of the oil circulation pumps and the over-temperature alarm. The temperature controller controls the heating tube and the oil circulation pumps. The temperature controller 95 is connected to a thermal resistor installed in the oil tank 2 to monitor the oil temperature changes in real time. When the oil temperature is too high, the oil circulation pump will cool the oil through the heat exchanger to lower the temperature. When the oil temperature is too low, the oil circulation pump will heat the oil through the heating tube to raise the temperature, so as to ensure that the oil temperature in the oil tank is within a range with small fluctuations.

[0030] The working principle of this embodiment is as follows: the periodic furnace body pours steel balls into the discharge port of the oil tank. The steel balls fall along the slide plate and side plate into the lifting bucket below. After the lifting bucket is fully loaded, the winch pulls the lifting bucket upward through the cable. During the upward process, the steel balls come into full contact with the cooling oil to complete the quenching. After leaving the oil tank, the lifting bucket rotates clockwise at the discharge slide plate, pouring the steel balls into the collection bucket along the discharge slide plate.
