Description

Technical Field

[0001] This utility model belongs to the technical field of baking devices for aluminum-based silicon carbide materials, and in particular relates to a constant temperature baking device for aluminum-based silicon carbide materials. Background Technology

[0002] Aluminum-based silicon carbide (AlSiC) is a particle-reinforced metal matrix composite material. It uses aluminum alloy as the matrix and silicon carbide particles as the reinforcement to form a multi-phase composite material. It has comprehensive superior properties that a single metal does not have and is widely used in electronic packaging, aerospace, new energy vehicles and other fields.

[0003] When producing aluminum-based silicon carbide products, baking is often required. However, most existing baking equipment is static baking. During static baking, the hollow tubular aluminum-based silicon carbide material being baked is fixed in a certain position, which leads to uneven heat transfer and different parts of the material being heated differently. This not only affects the baking quality of the aluminum-based silicon carbide material and causes unstable product performance, but also reduces production efficiency and consumes more energy. Utility Model Content

[0004] The purpose of this invention is to provide a constant temperature baking device for aluminum-based silicon carbide materials. Specifically, during the baking of tubular materials, a motor starts and drives a rotating shaft to rotate. This rotating shaft causes the tray, transmission plate, and partition plate to rotate around the shaft, achieving a revolution of the placement tray. Simultaneously, the rotation of the transmission plate drives a gear to move via a rotating shaft. The gear meshes with an inner ring rack, forcing the placement tray to rotate, allowing the tubular material to receive heat from all directions and angles. This significantly improves baking efficiency and uniformity, solving the problem that most existing baking devices are static, where the hollow tubular aluminum-based silicon carbide material being baked is fixed in a certain position during static baking.

Several guide plates 314 are fixedly connected to the side of the heating box 311 away from the inner wall of the left side of the baking oven 1.

[0062] Several guide plates 314 are installed at a certain angle on the heating box 311.

[0063] The circulation assembly 32 includes a fan 321 installed on the rear side of the oven 1. The air inlet end of the fan is equipped with an exhaust pipe 322. The end of the exhaust pipe 322 away from the heating box 311 extends into the interior of the oven 1 and is fixedly connected to the top of the oven 1. The air outlet end of the fan 321 is fixedly connected to an air supply pipe 323. The air supply pipe 323 extends into the interior of the oven 1 and is fixedly connected to the left and right sides of the oven 1.

[0064] The exhaust duct 322 is connected to the fan 321 via a flange.

[0065] One specific application of this embodiment is: electric heating wire 312: the electric heating wire 312 is based on Joule's law and uses a high resistivity material. When energized, electrons collide to generate heat, which is regulated by a temperature control device to achieve efficient and stable heat energy conversion.

[0066] When using this device to bake aluminum-based silicon carbide tubular material 226, the tubular material 226 is first placed on the placement tray 224 and positioned by the positioning pin 225 to prevent displacement and falling during the rotation of the tubular material 226 during baking. During the baking of the tubular material 226, the motor 211 is started, driving the rotating shaft 212 to rotate through the coupling. The rotating shaft 212 drives the tray 221, transmission plate 222 and partition plate 227 to rotate around their own axis. The tubular material 226 on the placement tray 224 moves in a circular motion around the rotating shaft 212 together with the placement tray 224. During the revolution of the tray 221, the gear 233 fixed on the rotating shaft 223 meshes with the annular internal rack 231 on the fixed rod 11. 31 is fixed, and gear 233 is forced to rotate when it revolves with tray 221, thereby driving shaft 223 and placement tray 224 to rotate. This allows the tubular material 226 to rotate while revolving, enabling it to receive heat from all directions and angles, improving baking uniformity. Tray 221 needs to rotate before baking the tubular material 226 and during placement and removal after baking, making it easier to place and remove the tubular material 226. The motor 211 can control the tray 221 to a suitable rotation speed. The working principle is the same as that of starting the motor 211 to drive the tray 221 to rotate during baking. In this device, there are three sets of placement components 22 and transmission components 23. The working principle and components of the three sets of placement components 22 and transmission components 23 are exactly the same.

[0067] During the baking of the tubular material 226, the operator controls the electric heating wire 312 to heat the air inside the heating chamber 311 via the control unit, so that the temperature inside the baking chamber 1 reaches the set temperature. After comparing the temperature with the set temperature value in real time by the control unit, the control circuit adjusts the on / off state or power of the electric heating wire 312 to maintain the temperature within the set range, thereby baking the tubular material 226. At the same time, the fan 321 extracts the hot air from the baking chamber 1 through the exhaust pipe 322. The extracted hot air is pressurized by the fan 321 and then delivered to the heating chambers 311 on both sides through the air supply pipe 323. The electric heating wires 312 inside the heating chambers 311 heat the incoming air. The heated air is then discharged through the vent 313 after reheating. During this process, the inclined guide plate 314 changes the flow direction of the hot air, causing it to be sprayed evenly into the baking oven 1 at a specific angle. After the hot air exchanges heat with the material, it is drawn back into the oven by the fan 321 through the exhaust pipe 322, forming a closed loop. In this process, the heating box 311 acts as the core of heat exchange, continuously heating the circulating airflow to the set temperature. The guide plate 314 changes the airflow direction and, in conjunction with the revolution and rotation of the placement part 2, ensures that the hot air evenly impacts the surface of the material, avoiding airflow blind spots or local overheating, and ultimately achieving a highly efficient, uniform, and constant-temperature baking effect.
