Description

Technical Field

[0001] This invention relates to the field of forging processing technology, and in particular to a descaling device for large flat billets. Background Technology

[0002] Before forging mechanical parts, steel billets need to be heated, usually to a red-hot state. After the red-hot billets are taken out of the heating furnace, a layer of oxide scale will form on the surface of the billets. The oxide scale is loosely connected to the main body of the billets and can easily peel off under the action of external force. In order not to affect the subsequent processing of parts, the oxide scale on the surface of the billets must be peeled off after they are taken out of the furnace, that is, the billets must be descaled.

[0003] For large flat billets (referring to iron discs with a diameter of 400-800mm), existing descaling devices generally use high-pressure nozzles installed above a conveyor belt. The large flat billets are transported by the conveyor belt and descaled by the high-pressure nozzles. However, when the large flat billets are placed onto the conveyor belt by a robotic arm, the center of the billets often deviates from the axis of the conveyor belt, making it difficult for the high-pressure nozzles to be properly aligned. Furthermore, the high-pressure nozzles are generally fixed in place. To ensure thorough descaling, i.e., to cover the large flat billets completely with the nozzles, it is necessary to increase the number of high-pressure nozzles and the power of the high-pressure pumps connected to the nozzles, resulting in increased energy consumption. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dephosphorization device for large flat blanks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Hydraulic telescopic rods are evenly distributed and at least three are fixedly installed on the upper end of the mounting plate. The projection of the axis of the hydraulic telescopic rod passes through the center of the rotating disk. An electric push rod is also fixedly installed on the upper end of the mounting plate and is horizontally arranged. The output end of the electric push rod is connected to a horizontally arranged distribution pipe. The projection of the axis of the distribution pipe is close to the center of the rotating disk. One end of the distribution pipe is connected to a water inlet pipe, and the lower end of the distribution pipe is provided with evenly distributed nozzles.

[0007] It also includes a control mechanism for the distribution pipe adapter, which controls the length of the distribution pipe connection.

[0008] Preferably, the control mechanism includes an electromagnet, an iron ring, a sealing ring, an elastic tube, and a fixing ring. The fixing ring is fixedly installed on the inner wall of the inlet end of the distribution pipe. The iron ring is located inside the distribution pipe. A sealing ring adapted to the inner wall of the distribution pipe is installed on the outer wall of the iron ring. An elastic tube is sealed between the end face of the iron ring and the end face of the fixing ring. The electromagnet is located inside the distribution pipe and attracts the iron ring to change its position inside the distribution pipe.

[0009] Preferably, a fixing block is fixedly installed on the rod body of the electric push rod, and a movable rod is inserted into the fixing block. The movable rod is arranged along the length direction of the electric push rod, and the end of the movable rod is fixedly connected to an electromagnet. A screw hole is provided on the fixing block 8, and a screw is installed in the screw hole. The end of the screw abuts against the movable rod 9. Loosening the screw allows the movable rod 9 to move freely, and tightening the screw fixes the movable rod 9.

[0010] Preferably, the outer side of the iron ring is covered with polytetrafluoroethylene (PTFE), which improves the corrosion resistance of the iron ring 11 and prevents the iron ring 11 from being corroded.

[0011] Preferably, the bottom end of the base plate is provided with a water outlet, and the top end of the base plate is rotatably installed with a cover plate. The cover plate reduces water splashing, ensures the cleanliness of the site environment, and saves water resources.

[0012] Preferably, a water tank is installed at the lower end of the base plate, a filter plate is installed on the inner wall of the water tank, the lower end of the side wall of the water tank is connected to the inlet end of the high-pressure pump, and the outlet end of the high-pressure pump is connected to the water inlet pipe.

[0013] Preferably, a sealing plate is installed on the side wall of the water tank, the sealing plate is located above the filter plate, and the sealing plate is sealed to the water tank.

[0014] Preferably, a raised ring is installed on the upper end of the mounting plate near the edge of the through groove.

[0015] Preferably, a geared motor is fixedly installed at the lower end of the base plate, and the output shaft of the geared motor is connected to the rotating disk.

[0016] Preferably, the output shaft of the hydraulic telescopic rod is provided with scale lines, which facilitates the determination of the elongation of each hydraulic telescopic rod 7 and facilitates the rapid centering of the large flat blank. In this embodiment, the number of hydraulic telescopic rods 7 is 4.

[0017] The beneficial effects of this invention are:

[0018] 1. In this device, a large flat blank is placed on a rotating disk, and the large flat blank is pushed by a hydraulic telescopic rod so that the center of the large flat blank coincides with the center of the rotating disk, achieving rapid centering. This allows the nozzle to be aligned with the large flat blank as much as possible, improving the utilization rate of the nozzle. To a certain extent, this can reduce the power of the high-pressure pump and achieve the purpose of energy saving.

[0019] 2. The descaling device for large flat billets is equipped with a control mechanism. The control mechanism controls the length of the distribution pipe connection, that is, according to the diameter of the large flat billet, the number of nozzles working on the distribution pipe can be adjusted in time, and nozzles that cannot descale the large flat billet can be shut off, thereby further improving the utilization rate of the nozzles.

[0020] 3. In this dephosphorization device for large flat blanks, a geared motor drives a rotating disc to rotate, thereby causing the large flat blank to rotate. With the nozzle in a fixed position, different areas of the large flat blank can be dephosphorized, improving the dephosphorization efficiency.

[0021] 4. The large flat billet dephosphorization device is equipped with a cover plate to reduce water splashing. A water tank is installed at the lower end of the bottom plate, and a filter plate is installed inside the water tank.

The lower end of the distribution pipe 6 is provided with evenly distributed nozzles 61.

[0029] It also includes a control mechanism adapted to the distribution pipe 6, which controls the length of the distribution pipe 6 connection.

[0030] The control mechanism includes an electromagnet 10, an iron ring 11, a sealing ring 12, an elastic tube 13, and a fixing ring 22. The fixing ring 22 is fixedly installed on the inner wall of the inlet end of the distribution pipe 6. The iron ring 11 is located inside the distribution pipe 6. The sealing ring 12, which is adapted to the inner wall of the distribution pipe 6, is installed on the outer wall of the iron ring 11. An elastic tube 13 is sealed between the end face of the iron ring 11 and the end face of the fixing ring 22. The electromagnet 10 is located inside the distribution pipe 6. The electromagnet 10 attracts the iron ring 11 and changes the position of the iron ring 11 inside the distribution pipe 6.

[0031] A fixing block 8 is fixedly installed on the rod body of the electric push rod 5. A movable rod 9 is inserted into the fixing block 8. The movable rod 9 is arranged along the length direction of the electric push rod 5. The end of the movable rod 9 is fixedly connected to the electromagnet 10. A screw hole is provided on the fixing block 8. A screw is installed in the screw hole. The end of the screw abuts against the movable rod 9. Loosening the screw allows the movable rod 9 to move freely. Tightening the screw fixes the movable rod 9.

[0032] The outer side of the iron ring 11 is covered with polytetrafluoroethylene (PTFE), which improves the corrosion resistance of the iron ring 11 and prevents it from being corroded.

[0033] The bottom plate 1 has a water outlet hole 16 at its lower end, and a cover plate 23 is rotatably installed on the upper end of the bottom plate 1.

[0034] A water tank 15 is installed at the lower end of the base plate 1. A filter plate 17 is installed on the inner wall of the water tank 15.

This allows the nozzle 61 to be aligned with the large flat blank as much as possible, improving the utilization rate of the nozzle. To a certain extent, this can reduce the power of the high-pressure pump 18 and achieve the purpose of energy saving.

[0040] The descaling device for large flat billets is equipped with a control mechanism. This mechanism controls the length of the distribution pipe 6, allowing for timely adjustment of the number of nozzles 61 operating on the distribution pipe 6 based on the diameter of the large flat billet. Nozzles 61 that cannot descal the large flat billet are shut off, preventing dry spraying. Specifically, the electromagnet 10 drives the iron ring 11 to move, which in turn causes the elastic tube 13 to contract or extend. A sealing ring 12, which is compatible with the inner wall of the distribution pipe 6, is installed on the outer wall of the iron ring 11, preventing water from entering the area between the iron ring 11 and the fixed ring 12. The nozzles between the iron ring 11 and the fixed ring 12 are in a closed state, further improving the utilization rate of the nozzles 6.

[0041] In this dephosphorization device for large flat blanks, the rotating disk 3 is driven to rotate by the reduction motor 2, thereby causing the large flat blank to rotate. With the nozzle 61 in a fixed position, different areas of the large flat blank can be dephosphorized, thus improving the dephosphorization efficiency.
