Movable heating skin stretch forming device and method

Abstract

The invention relates to a movable heating skin stretch forming device and method. The device at least comprises a stretch forming die, stretch forming clamps, a movable heating unit and a pulling force immediate regulation unit, wherein the stretch forming die is fixed to a die installing seat; the stretch forming clamps are disposed on the two sides of the stretch forming die through ascending-descending clamp installing seats; the movable heating unit is disposed on the periphery of the stretch forming die and comprises a three-dimensional moving mechanism, heating elements and thermodetectors, the heating elements and the thermodetectors are installed on the three-dimensional moving mechanism; the three-dimensional moving mechanism can drive the heating elements and the thermodetectorsto move above and around the stretch forming die for heating and temperature collection during skin stretch forming; the heating elements and the thermodetectors are connected and are in data information transmission with the pulling-force immediate regulation unit; and the pulling-force immediate regulation unit is connected with the ascending-descending clamp installing seats and controls the ascending-descending clamp installing seats to ascend and descend.

Description

technical field [0001] The invention relates to the technical field of plate thermoforming, in particular to a mobile heating skin stretching equipment and a stretching method. Background technique [0002] Skin stretching technology is an important technology in the field of sheet metal forming. The main principle of drawing process is as follows: figure 1 shown. The drawing die is fixed on a pressure platform that can move up and down, and the clamps distributed on both sides hold the sheet, and the sheet is formed by moving the die upward. There is also another form, the drawing die does not move, and the hydraulic cylinders are distributed at the clamping ends on both sides. When working, the clamping ends move down and the sheet is formed. In order to improve the drawing precision and reduce defects, a series of studies have been carried out on the drawing loading trajectory and loading parameters at home and abroad in recent years. At present, the skin stretching t...
