The utility model provides a glass hot bending machine, and belongs to the technical field of hot bending forming machine equipment, the glass hot bending machine is provided with a heating assembly for providing heat for glass hot bending, the heating assembly comprises a ceramic plate, a metal plate and a connecting piece for connecting the ceramic plate and the metal plate, a heating unit is arranged in the metal plate, N kidney-shaped holes suitable for penetrating of the connecting piece are formed in the ceramic plate, and the N kidney-shaped holes are communicated with the metal plate. Wherein N is an integer greater than or equal to 3; a straight line passing through the geometric center and along the shortest line segment direction of the binding surface is taken as an X axis, and a straight line passing through the geometric center and perpendicular to the shortest line segment is taken as a Y axis; the long axis directions of the N kidney-shaped holes extend in the direction deviating from the geometric center, and the long axis directions of any two adjacent kidney-shaped holes deviate from each other; at least part of the kidney-shaped holes have projection components in the X-axis direction and projection components in the Y-axis direction in the long-axis direction at the same time. The interface thermal stress generated by thermal expansion mismatch of ceramic and metal is effectively released, and the flatness of the heating assembly is ensured.
