A method for forming a high-pressure forming device in a hand tool handle, wherein the high-pressure forming device in the hand tool handle is the high-pressure forming device in the hand tool handle selected from the group consisting of the following claims 1 to 9, and is characterized in that (1) a workpiece tube blank is placed on a lower die, and an upper die arranged on a pressure head of a press machine is closed along with the descending of the pressure head; (2) The oil cylinders of the two pressure devices drive the sliding seat and the pressure applying heads to move, so that two ends of the workpiece tube blank are correspondingly inserted between the accommodating counter bores and the positioning columns of the two pressure applying heads one by one; (3) Starting an oil pump, feeding hydraulic oil into an inner hole of a workpiece tube blank through an oil inlet hole for internal high-pressure forming, plastically deforming the workpiece tube blank to realize expansion, applying axial thrust to two ends of the workpiece tube blank one by pressure applying heads of two pressure applying devices for supplementing materials, and reversing a three-position four-way electromagnetic valve to a middle position for maintaining pressure after the hydraulic oil reaches a set pressure value; (4) The reversing of a first electromagnetic valve and a second electromagnetic valve of the pressurizing device enables the gas-liquid pressurizing cylinder to be repeatedly and circularly switched between a pressurizing state and a resetting state, so that the pressure of hydraulic oil in the inner hole of the workpiece tube blank fluctuates to carry out high-pressure shaping, the workpiece tube blank generates micro-deformation to be better attached to a cavity, and the workpiece blank is molded into a workpiece blank; (5) When the workpiece tube blank is made of a material with low room temperature plasticity and difficult forming, the hydraulic oil is heated by the electric heater, and the temperature is controlled by the temperature controller, so that the plasticity of the workpiece tube blank is improved and the forming is easy; (6) The three-position four-way electromagnetic valve is reversed to release pressure, hydraulic oil in the inner hole of the workpiece blank flows back to the oil tank through the oil return hole, and the upper die rises along with the pressure head of the press to open the die; (7) When a workpiece blank needs to be processed with a hole groove, the hole groove processing device drives the drilling and milling power head to move to process the hole groove; (8) And the oil cylinders of the two pressing devices drive the sliding seat and the pressing heads to move in the opposite directions, so that the two pressing heads are separated from the two ends of the workpiece blank respectively, and then the workpiece blank is taken out.
