Cone forming mold

Abstract

The invention discloses a taper tube molding die. The taper tube molding die comprises a vertically-arranged inner die column, a first molding outer die and a second molding outer die, the first molding outer die and the second molding outer die are folded to be used for clamping the inner die column, and the first molding outer die and the second molding outer die are arranged around a vertical fixed shaft in an opening and closing manner; and when the first molding outer die and the second molding outer die are folded to be used for clamping the inner die column, a molding ring cavity used for molding a taper tube is formed amount the outer ring face of the inner die column and the first molding outer die and the second molding outer die. A molding pressing block is further installed on the inner die column to be used for abutting against a top arc line of a fan-shaped material in the process that the fan-shaped material is molded into the taper tube so as to limit axial displacement of the fan-shaped material along the inner die column, and the fan-shaped material is prevented from moving out of the molding ring cavity. According to the taper tube molding die, the part machining time can be greatly shortened, the part molding efficiency is improved, the quality of molded parts is stable, the surface quality is obviously improved, the part roundness is good, the one-time submitting and checking yield is high, the part molding process is simple in operation, and the requirement for the technical ability of an operator is low.

Description

technical field [0001] The invention relates to the field of cone forming, in particular to a cone forming die. Background technique [0002] The flame tube is a key component of the engine for fuel-air mixing and combustion. The materials of the rings at the head of the flame tube are GH1140 and GH3044 respectively, and the thickness of the material is t1.5. After rolling, the diameters at both ends of the cone 10 are required to be φ105, φ49, and the height is 90, as shown in the attached picture figure 1 shown. [0003] At present, the existing round rolling machines on the market have relatively large specifications, and are used for rolling round and conical tubes 10 with a diameter of φ320-6000mm. Since the diameter of the cone tube 10 at the head of the flame tube is small, it is not suitable for the existing round rolling machines on the market. machine. In the prior art, the cone 10 of the flame tube head is formed by manual beating, that is, a fitter uses a simp...
