Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating curing equipment technology, specifically to an internal cooling coating curing machine. Background Technology
[0002] Internally cooled drill bits are key tools in machining, and their internal cooling channels often require a wear-resistant or friction-reducing coating to improve performance. Traditional coating curing methods often involve external hot air heating or oven curing. However, due to the long and enclosed structure of the internal cooling channels, hot airflow cannot effectively penetrate into the channels, resulting in uneven coating curing, and even localized uncured or overheated areas, severely affecting the lifespan of the drill bit.
[0003] Existing equipment typically relies on fixed sealing structures or manual adjustment devices to address the issue of hot air introduction into the internal cooling channel. This results in problems such as insufficient sealing, unstable airflow, and difficulties in connecting the clamping structure with the air path. Furthermore, traditional ovens have a single hot air circulation path design, making it difficult to achieve directional and efficient heating of the internal cooling channel, leading to energy waste and high operational complexity. Therefore, there is an urgent need for an integrated device that can automatically adapt to internal cooling drill bits of different sizes, ensure stable hot airflow into the channel, and achieve efficient curing.

Since the second cavity 106 is separated from the first cavity 105 by the partition plate 501, the gas in the second cavity 106 can only be guided through the air guide hole 502 and the air guide groove to achieve the curing of the coating of the internal cold channel.

The hot drying chamber 102 of the oven structure 1 is equipped with a resistance heater, which can heat the air inside the hot drying chamber 102. The motor in the motor cover 104 introduces the gas in the hot drying chamber 102 into the air duct through the air inlet 109 via the centrifugal fan blades, and then through the first outlet of the air duct Air outlet 107 and second air outlet 108 are directed into the first cavity 105 and the second cavity 106. Since the second cavity 106 is separated from the first cavity 105 by the partition plate 501, the gas in the second cavity 106 can only be guided through the air guide hole 502 and the air guide groove to achieve coating curing of the internal cooling channel. The clamping structure 2 is a three-jaw chuck structure. The rotating pin 202 is inserted by a special tool to drive the rotating pin 202 to rotate. The rotating pin 202 drives the rotating chuck 203 to drive the transmission block 204 to perform centripetal linear transmission, thereby clamping and fixing the internal cooling drill bit 3. In this embodiment, the clamping end of the internal cooling drill bit 3 is mainly clamped and fixed, which makes it easier to connect the air guide groove of the contact pad 403 with the internal cooling channel of the internal cooling drill bit 3.
