Description

Technical Field

[0001] This utility model belongs to the field of metal flat strip processing technology, specifically relating to an automatic chip removal and cooling device. Background Technology

[0002] Titanium flat bars are long, thin strips of titanium alloy that play an important role in various industrial fields. Rolling is a common forming process for titanium flat bars during their production. However, after rolling, the surface of the titanium flat bars oxidizes under the influence of air, affecting the appearance and strength of the finished product. Therefore, it is necessary to introduce an oxide scale removal device to remove the oxide scale from the surface.

[0003] In related technologies, utility model publication CN220387487U discloses an automatic oxide removal device for titanium flat bars, belonging to the field of titanium flat bar processing technology. It includes a traction wheel, a guide wheel assembly, and a descaling module. The traction wheel and guide wheel assembly work together to guide the titanium flat bar through the descaling module, which removes the oxide layer from the passing titanium flat bar. A spray assembly is provided above the descaling module to spray the titanium flat bar after passing through the descaling module. The descaling module is located between the traction wheel and the guide wheel assembly. The descaling module includes a descaling mold and a fixing plate, which are detachably connected. A pre-grinding machine is provided between the traction wheel and the guide wheel assembly to pre-grind the titanium flat bar before it passes through the descaling module. By setting up the spray assembly and guide wheel assembly, it reduces the temperature of the titanium flat bar after descaling and prevents the increased surface activity of the titanium flat bar from reacting with oxygen and causing secondary oxidation, while also improving the fixing effect. However, the waste chips (oxide layer debris) generated during the peeling process of the above-mentioned devices are easy to get tangled on the equipment parts, affecting the processing accuracy and the stability of equipment operation; the cooling devices mostly use low-pressure spraying, which has poor chip breaking effect and low cooling efficiency, making it difficult to meet the production requirements of high speed and high precision.

[0035] Please refer to Figure 1-4 As shown, this embodiment provides an automatic dander removal and cooling device, including a housing 10 and a traction wheel assembly 20, a peeling assembly 30, and a first guide wheel assembly 40 sequentially installed inside the housing 10 along the traveling direction of a metal flat bar 60 (such as a titanium flat bar). The traction wheel assembly 20 is configured to drive the metal flat bar 60 to feed towards the peeling assembly 30; the peeling assembly 30 is used to remove the oxide layer on the surface of the metal flat bar 60; the first guide wheel assembly 40 cooperates with the traction wheel assembly 20 to radially limit the metal flat bar 60.

[0036] It also includes a high-pressure spray assembly 50, which includes:

[0037] Water storage tank 51, water storage tank 51 is used to store coolant;

[0038] The inlet of the circulation pump 52 is connected to the water storage tank 51 through the first pipe;

[0039] The pressurizing device 53 has its inlet end connected to the outlet end of the circulating pump 52 via a second pipe. The pressurizing device 53 is used to pressurize the coolant.

[0040] Nozzle 54 is installed inside housing 10 and located directly above the chip removal end of peeling assembly. The inlet end of nozzle 54 is connected to the outlet end of pressurization device 53 through a third pipe. Nozzle 54 is configured to spray coolant at an angle of 45-90 degrees to the traveling direction of metal flat bar 60, so as to break up waste chips and cool down metal flat bar 60.

[0041] Based on the above structure, this device drives the metal flat strip 60 to feed towards the peeling assembly 30 via the traction wheel assembly 20, using the mechanical action of the peeling assembly 30 to remove the surface oxide layer. Simultaneously, the high-pressure spray assembly 50 forms a closed-loop cooling system: coolant from the water tank 51 is drawn by the circulating pump 52, pressurized by the booster device 53 (such as a booster pump), and then sprayed at a vertical angle by the nozzle 54 to the chip discharge end of the peeling assembly 30. The high-speed liquid flow breaks up the peeled oxide layer debris, preventing it from entanglement or accumulation, and reduces the processing temperature rise of the metal flat strip 60 through liquid flow heat exchange. The first guide wheel assembly 40 cooperates with the traction wheel 21, using radial limiting of the upper and lower wheel sets to constrain the movement trajectory of the metal flat strip 60, ensuring its linear feed. Thus, this invention integrates feeding, peeling, cooling, and limiting functions, forming a closed-loop processing system that replaces manual intervention and improves processing efficiency. At the same time, high-pressure spraying simultaneously removes debris and cools the surface, avoiding the problems of debris residue and thermal deformation associated with traditional mechanical peeling.

[0042] In a preferred embodiment of this invention, the pressurizing device 53 is configured to pressurize the coolant to 5-10 MPa. The pressurizing device 53 controls the coolant pressure within this range, achieving an outlet velocity of 50-100 m / s at the nozzle 54, forming a high-speed liquid flow with both kinetic energy and impact momentum, sufficient to cut off oxide layer debris. This avoids the insufficient impact force of low-pressure (<5 MPa) liquid flow leading to debris entanglement, or the splashing and energy waste caused by high-pressure (>10 MPa) flow, achieving an optimal balance between energy consumption and effectiveness. The high-speed liquid flow increases the contact area with the metal flat strip 60, enhancing convective heat transfer and improving the cooling rate compared to atmospheric pressure spraying.

[0053] In a preferred embodiment of the present invention, a constant temperature control device is also provided in the water storage tank 51 to maintain the temperature of the coolant within the range of 20-30°C.

[0054] Based on the above structure, the constant temperature control device in the water storage tank 51 maintains the coolant temperature at 20-30℃ (accuracy ±1℃) through the semiconductor cooling / heating module, ensuring that the temperature difference between the spray liquid and the surface of the metal flat strip 60 is ≥15℃ (the surface temperature of the metal flat strip 60 during processing is ≤50℃), thus forming stable heat exchange conditions.
