Description

Technical Field

[0001] The utility model relates to the technical field of quenching oil tanks, in particular to a quenching oil tank for bolts. Background Art

[0002] Quenching is a key metal heat treatment process used to improve the physical and mechanical properties of metal materials. The core of this process is to adjust the structure of the metal at the micro level by rapidly cooling the metal material heated to the appropriate temperature. The main purpose of quenching is to increase the hardness and wear resistance of the metal, while adjusting its internal lattice structure to adapt it to specific industrial application requirements. When producing bolts, thermal processing is required to increase the mechanical strength to meet the use requirements.

[0003] When high-temperature bolts are placed in a quenching oil tank for quenching, the temperature of the quenching oil will increase. However, the existing quenching oil tank usually uses air flow to dissipate heat, which has a poor heat dissipation effect and is difficult to quickly cool the quenching oil, thereby reducing the quenching efficiency. Utility Model Content

[0004] The utility model aims to provide a quenching oil tank for bolts which can quickly cool down the quenching oil and improve the quenching efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A quenching oil tank for bolts comprises a bottom plate, two oil tanks are installed on the upper surface of the bottom plate, an electric push rod is rotatably installed on the upper surface of the bottom plate, a mounting plate is installed at the end of the telescopic end of the electric push rod, an oil suction pipe and an oil outlet pipe are respectively connected to the lower surface of the mounting plate, and a rotating mechanism capable of driving the electric push rod to rotate is arranged on the upper surface of the bottom plate. A cooling tank is installed on the upper surface of the bottom plate, a refrigerator is installed on the outer surface of the cooling tank, a spiral tube is arranged inside the cooling tank, a circulating pump is installed on the top of the cooling tank, a first hose is connected to the suction end of the circulating pump, the end of the first hose is connected to the oil suction pipe, the output end of the circulating pump is connected to the spiral tube, the end of the spiral tube passes through the outer side of the cooling tank and is connected to the second hose, and the end of the second hose is connected to the oil outlet pipe.

[0007] It can be seen that by extending the oil suction pipe and the oil outlet pipe into the oil tank and starting the circulation pump, the circulation pump draws the quenching oil from the oil suction pipe, passes through the spiral tube, and then discharges it into the oil tank from the oil outlet pipe. Since the refrigerator cools the coolant in the cooling tank, the quenching oil can quickly cool down when it passes through the spiral tube. The two oil tanks are used alternately. While one oil tank is in use, the other oil tank can have more time to cool down, thereby ensuring that the quenching oil can reach a suitable temperature for quenching the bolts, and will not cause production pauses due to waiting for cooling, thereby achieving the purpose of continuous quenching of bolts and improving quenching efficiency.

[0008] Furthermore, the rotating mechanism includes a motor installed on the upper surface of the base plate, a gear is installed on the end of the motor output shaft, a gear ring is sleeved on the outer surface of the electric push rod, and the gear is meshed and connected with the gear ring.

[0009] By starting the motor to drive the gear to rotate, the gear and the gear ring are meshed with each other, so the electric push rod can be driven to rotate. The rotation of the electric push rod drives the position of the mounting plate to change, thereby achieving the purpose of alternating cooling of the two oil tanks.

[0010] Furthermore, an oil extraction hood is installed at the end of the oil suction pipe, and a filter is arranged inside the oil extraction hood.

[0011] Since the quenching oil contains impurities such as metal debris, these impurities can be filtered out through the setting of the filter to prevent them from entering the oil suction pipe and causing blockage of subsequent pipelines and damage to the circulating pump.

[0012] Furthermore, a filter cartridge is disposed inside the oil tank, and a handle is installed on the outer surface of the filter cartridge.

[0013] When the handle is lifted to drive the filter cartridge upward, impurities in the quenching oil can be filtered out, making it easier to clean.

[0014] Furthermore, a fixing plate is installed on the upper surface of the mounting plate, and the fixing plate is sleeved on the outside of the first hose and the second hose.

[0015] By setting the fixing plate, the first hose and the second hose can be fixed to prevent them from swinging randomly and causing wear.

[0016] Furthermore, the length of the oil suction pipe is shorter than the length of the oil outlet pipe.

[0017] When the electric push rod drives the mounting plate to descend, the oil suction pipe is located on the upper side of the quenching oil, and the oil outlet pipe is located on the lower side of the quenching oil. Therefore, the quenching oil with a higher temperature on the upper side is pumped away for cooling, and then flows back to the bottom side of the quenching oil after cooling, which makes it easier to form a circulating flow of the quenching oil and improve the uniformity of the quenching oil temperature distribution.

DETAILED DESCRIPTION

[0023] The utility model is described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a quenching oil tank for bolts includes a base plate 100, two oil tanks 101 are installed on the upper surface of the base plate 100, an electric push rod 102 is rotatably installed on the upper surface of the base plate 100, a mounting plate 103 is installed at the end of the telescopic end of the electric push rod 102, the lower surface of the mounting plate 103 is respectively connected to an oil suction pipe 104 and an oil outlet pipe 105, and a rotating mechanism 200 that can drive the electric push rod 102 to rotate is provided on the upper surface of the base plate 100. A cooling tank 106 is installed on the upper surface of the base plate 100, a refrigerator 107 is installed on the outer surface of the cooling tank 106, a spiral tube 109 is arranged inside the cooling tank 106, a circulating pump 108 is installed on the top of the cooling tank 106, a first hose 110 is connected to the suction end of the circulating pump 108, an end of the first hose 110 is connected to the oil suction pipe 104, an output end of the circulating pump 108 is connected to the spiral tube 109, an end of the spiral tube 109 passes through the outside of the cooling tank 106 and is connected to a second hose 111, and an end of the second hose 111 is connected to the oil outlet pipe 105.

[0025] When in use, first pour quenching oil into both oil tanks 101, then put the heated bolt into one of the oil tanks 101 for quenching, and use the two oil tanks 101 alternately. When quenching is completed, the electric push rod 102 can be driven to rotate by the rotating mechanism 200, so that the electric push rod 102 drives the mounting plate 103 to rotate to the top of the oil tank 101, and the electric push rod 102 drives the mounting plate 103 to descend, so that the oil suction pipe 104 and the oil outlet pipe 105 are both extended into the quenching oil, and then the circulating pump 108 is started, and the circulating pump 108 draws the quenching oil from the oil suction pipe 104 and passes through the first hose 1 10 enters the spiral tube 109. Since the refrigerator 107 cools down the coolant in the cooling tank 106, the quenching oil can be quickly cooled down when passing through the spiral tube 109. The cooled quenching oil flows back to the oil tank 101 from the second hose 111 and the oil outlet pipe 105, so that the quenching oil with increased temperature can be quickly cooled down. When the quenching oil in the current oil tank 101 is cooled down, the other oil tank 101 can carry out the quenching operation of the bolts, and the production will not be stopped due to waiting for cooling, so the purpose of continuous quenching operation of the bolts is achieved, and the quenching efficiency is improved.

[0026] Specifically, the rotating mechanism 200 includes a motor 201 installed on the upper surface of the base plate 100, a gear 202 is installed on the end of the output shaft of the motor 201, a gear ring 203 is sleeved on the outer surface of the electric push rod 102, the gear 202 is meshed with the gear ring 203, and the motor 201 is started to drive the gear 202 to rotate. Since the gear 202 and the gear ring 203 are meshed with each other, the electric push rod 102 can be driven to rotate. The rotation of the electric push rod 102 drives the position of the mounting plate 103 to change, thereby achieving the purpose of alternating cooling of the two oil tanks 101.

[0027] Specifically, an oil extraction hood 300 is installed at the end of the oil suction pipe 104, and a filter screen 301 is arranged inside the oil extraction hood 300. Since the quenching oil contains impurities such as metal debris, these impurities can be filtered through the setting of the filter screen 301 to prevent them from entering the oil suction pipe 104 and causing blockage of subsequent pipelines and damage to the circulation pump 108.

[0028] Specifically, a filter cartridge 400 is disposed inside the oil tank 101 , and a handle 401 is installed on the outer surface of the filter cartridge 400 . When the handle 401 is lifted to drive the filter cartridge 400 upward, impurities in the quenching oil can be filtered out, which is convenient for cleaning.

[0029] Specifically, a fixing plate 500 is installed on the upper surface of the mounting plate 103, and the fixing plate 500 is sleeved on the outside of the first hose 110 and the second hose 111. By setting the fixing plate 500, the first hose 110 and the second hose 111 can be fixed to prevent them from swinging randomly and causing wear.

[0030] Specifically, the length of the oil suction pipe 104 is shorter than that of the oil outlet pipe 105. When the electric push rod 102 drives the mounting plate 103 to descend, the oil suction pipe 104 is located on the upper side of the quenching oil, and the oil outlet pipe 105 is located on the lower side of the quenching oil. Therefore, the quenching oil with a higher temperature on the upper side is pumped away for cooling, and then flows back to the bottom side of the quenching oil after cooling, which makes it easier to form a circulating flow of the quenching oil and improve the uniformity of the temperature distribution of the quenching oil.

[0031] The above is a detailed description of the utility model in combination with specific embodiments, and it cannot be determined that the specific implementation methods of the utility model are limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, making several equivalent substitutions or obvious modifications without departing from the concept of the utility model, and having the same performance or use, should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
