Description

Technical Field

[0001] This utility model relates to the technical field of high-speed steel ingot processing equipment, and more specifically, it relates to a spray-type cooling device for expanding the shape of high-speed steel ingots. Background Technology

[0002] High-speed steel, a tool steel with high hardness, high wear resistance, and high heat resistance, is widely used in machinery manufacturing, mold processing, and other fields. During the production of high-speed steel ingots, their external dimensions and internal structure need to be adjusted through ingot expansion processes (such as forging and rolling). After ingot expansion, the temperature of the high-speed steel ingot is extremely high (typically reaching 800-1200℃), requiring timely cooling. If cooling is not timely or uneven, thermal stress will be generated inside the ingot, leading to defects such as cracks and deformation, severely affecting the subsequent processing quality and finished product performance.

[0003] Among existing cooling technologies, air cooling is inefficient and prone to local temperature differences (axial temperature difference can reach about 10°C), making it difficult to meet the needs of rapid cooling. Although traditional fixed spray devices have a faster cooling speed than air cooling, the nozzle angle and coverage area are fixed, making it difficult to achieve no dead angle spraying on irregularly shaped ingots after expansion. This results in significant differences in cooling rates in different areas of the steel ingot, which in turn causes thermal stress deformation. If the traditional spray cooling mechanism is rotated directly to improve the uniformity of spraying, the coolant delivery relies heavily on hoses, which can cause the hoses to become entangled and twisted as the mechanism rotates. This not only directly blocks the normal delivery of coolant but may also cause leakage problems due to damage to the pipes.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a spray-type cooling device for expanding the shape of high-speed steel ingots. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spray-type cooling device for expanding the shape of high-speed steel ingots.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spray cooling device for expanding the shape of high-speed steel ingots, comprising a high-speed steel ingot placement platform and a rotary spray cooling mechanism located above the high-speed steel ingot placement platform; The rotary spray cooling mechanism includes a top plate with an embedded liquid inlet pipe. A cylindrical liquid storage tank is rotatably connected to the bottom of the top plate, and a top pipe is interconnected to the top of the cylindrical liquid storage tank. The liquid inlet pipe is inserted into the top pipe, and the two are connected by a rotary sealing structure. The top of the liquid inlet pipe is connected to the coolant delivery pipe through a solenoid valve. Multiple electric spray nozzles arranged in a circular array are installed at the bottom of the cylindrical liquid storage tank.

[0007] Preferably, an annular guide rail is installed around the bottom of the top plate around the liquid inlet pipe, and multiple sliders arranged in a circular array are slidably connected to the bottom of the annular guide rail. The bottom of the sliders is connected to the cylindrical liquid storage tank through a vertical rod.

[0008] Preferably, the rotary sealing structure includes a rotating ring fixed on the inner wall of the top pipe and a stationary ring fixed on the outer wall of the inlet hard pipe, with the rotating ring and the stationary ring sealed by end face contact.

[0009] Preferably, a handle is fixedly connected to the outer wall of the cylindrical liquid storage tank and surrounds it.

[0010] Preferably, a support plate is fixedly connected to both sides of the bottom end of the top plate, and a base is fixedly connected to the bottom end of the support plate. The top end of the base is connected to the high-speed steel ingot placement platform through an electric hydraulic rod.

[0011] Preferably, it also includes a control device for controlling the solenoid valve to automatically replenish the liquid in the cylindrical liquid storage tank.

[0012] Preferably, the controller includes: Power module: Provides power to the electrical components on the liquid replenishment control device; The liquid level sensor is installed inside the cylindrical liquid storage tank to detect the liquid level inside the tank in real time and send the liquid level information to the microprocessor control module in the form of a signal. Microprocessor control module: Based on the liquid level signal transmitted by the liquid level sensor in the cylindrical liquid storage tank, the liquid level value is compared with the preset lower and upper threshold values. When the liquid level is lower than the set lower limit value, a signal to open the solenoid valve is sent to the drive module; when the liquid level reaches the set upper limit value, a signal to close the solenoid valve is sent to the drive module. Drive module: Drives the solenoid valve to open and close based on the signals transmitted from the microprocessor control module.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model allows the cylindrical liquid storage tank and top pipe to rotate stably relative to the top plate, inlet hard pipe, and coolant delivery pipe by manual pushing. The rotating sealing structure ensures that the coolant flows steadily from the inlet hard pipe into the cylindrical liquid storage tank and avoids leakage during rotation. This, in turn, drives the electric nozzles arranged in a circular array at the bottom to rotate synchronously. The electric nozzles spray the coolant in the cylindrical liquid storage tank. The rotation action achieves all-round, no-dead-angle spraying of high-speed steel ingots. This not only solves the problem of uneven cooling in traditional fixed spraying, but also effectively avoids the risks of pipe entanglement, twisting, and leakage because the coolant delivery pipe and inlet hard pipe remain stationary and do not need to rotate. This solves the problems in the background technology. 2. This utility model uses an electric hydraulic rod to raise and lower the high-speed steel ingot placement platform. The height of the high-speed steel ingot placement platform can be flexibly adjusted according to the actual situation of the high-speed steel ingot after the ingot shape is expanded, so that the high-speed steel ingot is always within the optimal spray range of the electric nozzle. 3. This utility model is equipped with a control device that uses a solenoid valve to automatically replenish the coolant in the cylindrical storage tank. On the one hand, it can completely replace manual replenishment, avoiding the problem of the coolant level in the storage tank being too low due to staff negligence, which could cause the electric nozzle to spray dry and be damaged or the cooling to be interrupted. It also prevents excessive manual replenishment from causing coolant overflow and waste, significantly reducing labor costs and material losses. On the other hand, the control device can dynamically adjust the opening and closing degree of the solenoid valve and the replenishment time according to the real-time liquid level in the storage tank, ensuring that the liquid level in the storage tank is always maintained in the optimal range. This allows the electric nozzle to maintain a stable spray pressure and flow rate, avoiding sudden changes in the cooling rate of the high-speed steel ingot due to liquid level fluctuations, thereby ensuring the uniformity of steel ingot cooling and reducing the risk of thermal stress deformation.

[0016] like Figure 1-5As shown, this utility model provides a spray cooling device for expanding the shape of high-speed steel ingots, including a high-speed steel ingot placement platform 1 and a rotary spray cooling mechanism 2 located above the high-speed steel ingot placement platform 1. The rotary spray cooling mechanism 2 includes a top plate 201, on which an inlet rigid pipe 202 is embedded and fixed. An annular guide rail 209 is mounted around the bottom of the top plate 201 and surrounding the inlet rigid pipe 202. Multiple sliders 210 arranged in a circular array are slidably connected to the bottom of the annular guide rail 209. The bottom of each slider 210 is connected to a cylindrical liquid storage tank 203 via a vertical rod 211 (to allow the cylindrical liquid storage tank 203 to rotate relative to the top plate 201). A top pipe 204 is interconnected to the top of the cylindrical liquid storage tank 203. The inlet rigid pipe 202 is inserted into the top pipe 204, and the two are connected by a rotary sealing structure 205 (the rotary sealing structure 205 includes components fixed to the inner wall of the top pipe 204). The rotating ring 2051 and the stationary ring 2052 are fixed on the outer wall of the liquid inlet hard pipe 202. The rotating ring 2051 and the stationary ring 2052 are sealed by end face contact. The top of the liquid inlet hard pipe 202 is connected to the coolant delivery pipe 207 through the solenoid valve 206. The bottom of the cylindrical liquid storage tank 203 is equipped with multiple electric nozzles 208 arranged in a circumferential array. The operator manually pushes the cylindrical liquid storage tank 203 to rotate (the outer wall of the cylindrical liquid storage tank 203 is fixedly connected to the handle 212 around it, which makes it easy for the operator to push it), which drives the electric nozzles 208 to rotate, thereby performing rotating spraying to spray and cool the high-speed steel ingots (after the ingot shape is expanded) placed on the high-speed steel ingot placement platform 1.

[0017] In use, the expanded high-speed steel ingot is placed on the high-speed steel ingot placement platform 1. Coolant is delivered to the inlet rigid pipe 202 via the coolant delivery pipe 207, and the flow of coolant is controlled by the solenoid valve 206. The inlet rigid pipe 202 is embedded and fixed on the top plate 201 and remains stationary. The coolant delivery pipe 207 connected to its top also does not need to rotate and is only responsible for stable delivery of coolant. The bottom end of the inlet rigid pipe 202 is inserted into the top pipe 20 at the top of the cylindrical liquid storage tank 203. Inside the coolant delivery pipe 207, the coolant enters the cylindrical reservoir 203 via the inlet hard pipe 202 and the top pipe 204. The cylindrical reservoir 203 is slidably engaged with the annular guide rail 209 at the bottom of the top plate 201 via the slider 210 connected by the vertical rod 211. The operator can manually push the cylindrical reservoir 203 and the top pipe 204 to make them rotate stably relative to the top plate 201, the inlet hard pipe 202, and the coolant delivery pipe 207. (During the rotation, the cylindrical reservoir...) The liquid tank 203 drives the slider 210 to rotate, and the slider 210 slides along the annular guide rail 209. The rotating sealing structure 205 (the moving ring 2051 on the inner wall of the top pipe 204 rotates with the cylindrical liquid storage tank 203, and the stationary ring 2052 on the outer wall of the liquid inlet hard pipe 202 remains fixed, and the two achieve dynamic sealing through end face contact) ensures that the coolant flows stably from the liquid inlet hard pipe 202 into the cylindrical liquid storage tank 203 and avoids leakage during rotation. This drives the electric nozzles 208 arranged in a circular array at the bottom to rotate synchronously. The electric nozzles 208 spray the coolant in the cylindrical liquid storage tank 203. The rotation action achieves all-round spraying of the high-speed steel ingot without dead angles. This not only solves the problem of uneven cooling of traditional fixed spraying, but also effectively avoids the risks of pipe entanglement, twisting and leakage because the coolant delivery pipe 207 and the liquid inlet hard pipe 202 always remain stationary and do not need to rotate. Finally, it achieves efficient and uniform cooling of the high-speed steel ingot after the ingot shape is expanded.

[0018] Furthermore, support plates 3 are fixedly connected to both sides of the bottom end of the top plate 201, and a base 4 is fixedly connected to the bottom end of the support plate 3. The top of the base 4 is connected to the high-speed steel ingot placement platform 1 via an electric hydraulic rod 5. The electric hydraulic rod 5 can be used to raise and lower the high-speed steel ingot placement platform 1. The height of the high-speed steel ingot placement platform 1 can be flexibly adjusted according to the actual situation of the high-speed steel ingot after the ingot shape is expanded (such as the difference in diameter and thickness of different specifications of ingots), so that the high-speed steel ingot is always within the optimal spray range of the electric nozzle 208. In addition, this utility model is also equipped with a control device for controlling the solenoid valve 206 to realize the automatic replenishment of liquid in the cylindrical liquid storage tank 203. On the one hand, it can completely replace the manual liquid replenishment operation and avoid the storage tank from being damaged due to the negligence of the staff. If the coolant level in the tank is too low, it can cause the electric nozzle 208 to spray dry and become damaged or interrupt cooling. It also prevents excessive manual replenishment from causing coolant overflow and waste, significantly reducing labor costs and material losses. On the other hand, the controller can dynamically adjust the opening and closing degree of the solenoid valve 206 and the replenishment time according to the real-time liquid level in the tank, ensuring that the liquid level in the tank is always maintained in the optimal range. This allows the electric nozzle 208 to maintain a stable spray pressure and flow rate, avoiding sudden changes in the cooling rate of the high-speed steel ingot due to liquid level fluctuations. This ensures the uniformity of steel ingot cooling and reduces the risk of thermal stress deformation. The following is the specific structure of the controller, which includes a power module, a liquid level sensor, a microprocessor control module, and a drive module.

[0019] In use, the power module provides stable power support to the electrical components (such as the level sensor, microprocessor control module, drive module, and solenoid valve 206) in the entire liquid replenishment control process. The level sensor detects the coolant level inside the cylindrical reservoir 203 in real time and converts the level information into an electrical signal, which is then transmitted to the microprocessor control module. After receiving the signal, the microprocessor control module compares the real-time level value with the preset lower and upper threshold values. If the level is lower than the lower threshold, it immediately sends a command to the drive module to open the solenoid valve 206. If the level reaches the upper threshold, it sends a command to close the solenoid valve 206. After receiving the signal from the microprocessor control module, the drive module converts it into a power signal that can drive the solenoid valve 206 to open or close, thereby realizing the automatic replenishment and cessation of coolant in the cylindrical reservoir 203 and ensuring that the level is always maintained within the set range.
