The invention relates to a hot pressing device for high temperature adhesive curing. Including: end cover (1), bolt (2), force bar (3), base (4), magnet (5), high temperature rubber pad (7), electric heater (8), electrode (9), lead hole (10), bearing (11), mandrel (12); the base (4) is a cylindrical structure with an inverted "U" shape in cross section, and the upper bottom surface is provided with a through hole, and the inner wall of the through hole is provided with a thread; the base The seat (4) provides support, and the magnet (5), high-temperature rubber pad (7), and electric heater (8) are arranged inside it; the magnet (5) provides attractive force, and the upper end of the magnet (5) has an internal thread, and the direct core The mandrel thread (12c) of axle (12) connects. The advantage of the invention is that both the temperature and the applied force can be adjusted to meet the condition of multiple curing of the high-temperature glue. The device is simple in design, precise in control and easy to operate.
