Problems solved by technology

[0003] The heating method of the temperature-controlled heating device of the existing glass hot-bending equipment is generally to heat the circular heating tube and transmit heat through a thin tungsten steel or alloy vapor chamber on the top. This heating method, due to the tungsten steel or The thermal conductivity of the alloy vapor chamber is low, and it is easy to oxidize and ash at high temperatures, resulting in a short service life, and it is also difficult to replace the heating body. In addition, the existing assembly and fixing methods also have shortcomings: One side of the heat conduction plate is fixed to the heating plate with a short screw, and another short screw is used to pass through the heat shield to fix it on the heating plate on one side of the support plate. Assembly positioning

Abstract

The invention discloses a temperature control heating device used for changing heating and assembly modes of glass hot bending equipment. The device comprises a supporting plate, a heat insulation plate and a heating body, wherein the heat insulation plate and the heating body are sequentially arranged on the supporting plate; the heating body is a ceramic heating body which is electrified and heated, and at least two through holes are formed in the supporting plate, the heat insulation plate and the functional ceramic heating body; screws are arranged in the through holes, and the screws downwards penetrate through the through holes in sequence from the functional ceramic heating body and are locked on the supporting plate through nuts. A traditional heating tube is replaced by the functional ceramic heating body, so that the heat conductivity is improved, the heat transfer speed is high, the heat conduction is uniform, oxidization and dust raising are not likely to happen at high temperature, the service life is prolonged, and the heating body can be replaced conveniently; besides, the heating body and the heat conduction plate can be integrated; the screws penetrate through thewhole plate layers to facilitate assembly and positioning between the plate layers, the plate layers are not easy to loosen, and the occurrence probability of the burst phenomenon of a common heatingbody is reduced.

Description

technical field [0001] The invention relates to the technical field of glass hot-bending equipment, in particular to a temperature-controlled heating device for glass hot-bending equipment that changes heating and assembly methods. Background technique [0002] Hot bending glass is a curved glass made of flat glass heated and softened, shaped in a mold, and then annealed. Hot bending glass can be made into glass with various radians, and is widely used in front and rear covers of mobile phones, car interiors, front and rear covers of electronic products, sightseeing elevators, lobby halls, rotating top floors, roof lighting, street passages, viewing windows, etc. occasion. The forming temperature of hot bending glass is generally around the softening transition point of the glass, about 800°C. The temperature is controlled by low temperature, medium temperature control, high temperature forming, annealing, and cooling forming. Precise control of molding temperature and s...
