Description

Technical Field

[0001] This utility model belongs to the field of electrical technology, specifically an automatic oxide scale removal device for high-temperature billets. Background Technology

[0002] In forging production, a hard and brittle oxide scale forms on the surface of the metal billet heated to high temperatures. If not removed before forging, this scale will not only severely reduce the quality and dimensional accuracy of the forgings by being pressed into the workpiece surface, but will also rapidly wear down expensive dies like an abrasive. Traditional methods of removing oxide scale by manual hammering or wire brushing are inherently limited by low efficiency, uneven cleaning, high labor intensity, and inability to adapt to the pace of automated production lines. Therefore, developing a dedicated oxide scale removal device that can operate efficiently, stably, and in an automated integrated manner has become a key technological step in improving forging quality, ensuring production cycle time, and reducing die wear and production costs.

[0003] In view of this, an automatic oxide scale removal device for high-temperature billets is proposed. Utility Model Content

[0033] Example, refer to Figures 1 to 3 An automatic oxide scale removal device for high-temperature billets includes a base plate 3, a water storage mechanism, an energy storage mechanism, a water spraying mechanism, and a water spraying box support 56.

[0034] The water storage mechanism includes a water tank 7, a motor 9, a coupling 4, and a high-pressure water pump 1. Each of the motor 9, coupling 4, and high-pressure water pump 1 forms a loop assembly. The water storage mechanism contains one or more loop assemblies. One loop assembly can work normally, while the other loop assemblies serve as supplementary pressure loops. They can be used for rapid energy replenishment and release when the production cycle speeds up. In this embodiment, two assemblies are used as an example. The high-pressure water pump 1, coupling 4, water tank 7, and motor 9 are all installed on the base plate 3. The front end of the water tank 7 is equipped with an inlet filter element 12, a level switch 16, and a water pipe A connected to an external water source. The inlet filter element 12 is used to filter external water. There are three sets of level switches 16, which respectively detect the lowest level, the highest level, and the replenishment level in the water tank 7.

[0039] Safety valve 35 is connected to high-pressure water control valve 24, which is installed on base plate 3. Safety valve 35 has a set value. If the set value is exceeded, the water will be automatically drained back into water storage tank 7 for protection.

[0040] The energy storage mechanism includes an accumulator 2, a one-way valve 30, and a hydraulic control valve 39; the accumulator 2 and the hydraulic control valve 39 are fixedly installed on the accumulator bracket 8, and the accumulator bracket 8 is installed on the base plate 3, wherein the accumulator 2 is used to store energy.

[0041] One end of the check valve 30 is connected to a water pipe leading to the accumulator 2, and the other end of the check valve 30 is connected to the high-pressure water control valve 24.

[0042] The accumulator 2 is also connected to the water tank 7 via a water pipe C. A high-pressure ball valve 46 is installed on the water pipe C. The high-pressure ball valve 46 is mainly used to release the energy in the accumulator 2 back to the water tank 7 when the accumulator is shut down for maintenance.

[0043] The accumulator 2 is also equipped with a water pipe D that is connected to the high-pressure water control valve 24 in the water spraying mechanism. The water pipe D is equipped with a pressure switch 45, a pressure sensor 59 and a pressure gauge 60, which facilitates the observation of the pressure value and comparison with the pressure value in the human-machine interface control box 61.

[0044] The water storage mechanism and energy storage mechanism are placed on the base plate 3. Adjustable feet 10 are provided below the base plate 3. The water spraying mechanism is placed next to the base plate 3.

[0045] The water spraying mechanism includes a water spraying tank 6, a water spraying ring 5, a slide rail 54, and a temperature measuring probe 58; the water spraying tank 6 is fixedly installed on the water spraying tank bracket 56, and the slide rail 54 passes through the water spraying tank 6; the temperature measuring probe 58 is fixedly installed outside the water spraying tank 6 to detect the temperature of the billet passing through the slide rail 54; the water spraying ring 5 is placed in the water spraying tank 6 and surrounds the slide rail 54.

[0046] The water spray ring 5 is equipped with multiple nozzles 62, all of which face the slide rail 54; the part of the slide rail 54 located in the water spray ring 5 is hollow, which facilitates the billet to be sprayed from all directions.

[0047] A high-pressure water control valve 24 is provided above the water spray ring 5, which is connected to the water outlet pipe of the accumulator 2;

[0048] Below the spray tank 6 is a sedimentation tank 57, which is used to catch the oxide scale and water falling from the spray tank 6. The sedimentation tank 57 is equipped with a water-sludge separation device. The separated water is returned to the external circulation water circuit of the equipment for continued use. The oxide scale is cleaned regularly.

[0049] A human-machine interface control box 61 is installed on the accumulator bracket 8. The human-machine interface control box 61 is connected to each PLC and can set and display data such as pressure compensation value, safety valve 35, pressure switch 45 and pressure sensor 59, so that the operator can monitor the system operation status and make corresponding adjustments and processing.

[0050] In addition to the above, this device is equipped with multiple alarms and safety protections. Mechanically, both sets of pressure replenishment devices have two safety valves 35 for double protection. Electrically, the pressure sensor 59 has an internal maximum alarm value and is equipped with a pressure switch 45 for double protection. Furthermore, the pressure sensor 59 is equipped with a wire breakage protection alarm, and the motor 9 has overload protection and temperature detection probe alarm mechanisms.

[0051] The working principle of this utility model is as follows: (Reference) Figures 1-3When the temperature probe 58 detects that a high-temperature billet is sliding from the slide rail 54 to the water spray tank 6, the hydraulic control valve 39 is activated, which opens the high-pressure water control valve 24 above the water spray ring 5, releasing the pressure in the accumulator 2. Water is sprayed from the accumulator 2 through the water spray ring 5 from the nozzles 62 in four directions onto the high-temperature billet passing through the water spray ring 5, causing the oxide scale on the surface of the high-temperature billet and the sprayed water to fall into the sedimentation tank 57 for sedimentation and separation.

[0052] Pressure sensor 59 is connected to the PLC to detect real-time water pressure and displays the pressure data on the human-machine interface control box 61. It also automatically replenishes energy or pauses pressure replenishment based on set values. When the water pressure is lower than the set value, the accumulator hydraulic control valve 39 opens, causing the high-pressure water control valve 24 between the water storage mechanism and the energy storage mechanism to open. Motor 9 rotates, and coupling 4 drives the high-pressure water pump 1 to operate. The high-pressure water pump 1 draws water from the water storage tank 7. After flowing out of the high-pressure water pump 1, the water passes through the safety valve 35, the high-pressure water control valve 24, and the check valve 30 to replenish energy in the accumulator 2 until the set water pressure is reached. At this point, pressure replenishment stops, the high-pressure water control valve 24 closes, and the check valve 30 maintains pressure in the accumulator 2 circuit. The water pumped by the high-pressure water pump 1 returns to the water storage tank 7 for circulation. Simultaneously, pressure switch 45 is connected to the PLC and judges the pressure based on the set value. If the pressure exceeds the set value, all motors 9 are shut down, and pressure replenishment stops.

[0053] The water storage tank 7 is automatically replenished by a solenoid water valve 13 controlled by three high, medium, and low level switches 16. When the water level in the storage tank 7 reaches the highest level, the solenoid water valve 13 closes, stopping water replenishment; when the water level in the storage tank 7 reaches the replenishment level, the solenoid water valve 13 opens, automatically replenishing water; when the water level in the storage tank 7 reaches the lowest level, an alarm is triggered, and the high-pressure water pump 1 stops working to prevent it from burning out. Manual water replenishment can also be performed via ball valve A17.

[0054] Due to the adoption of the above technical solution, this utility model has at least the following beneficial effects: the system can be self-adjusted through pressure detection and the function of the accumulator; the slide is hollow and the nozzle arrangement direction can spray the billet in all directions, effectively removing the oxide scale, reducing the wear on the mold, and reducing the surface defects of the product, thus effectively controlling the scrap rate; the spraying time is short, improving production efficiency, and the billet temperature is not affected, thus reducing production costs.

[0055] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
