Abstract

A thermoplastic material flexible forming device, including a multi-point flexible mold, a locking device and a flexible edge-holding system, the multi-point flexible mold is embedded in the locking device, and a flexible edge-holding system is installed on the locking device; the multi-point flexible The mold consists of a square frame formed by connecting four pressure plates. The high temperature resistant rubber for sealing is arranged in the square frame. The high temperature resistant rubber for sealing is provided with multiple groups of square grids interspersed with carbon fiber filaments. The basic unit body, carbon fiber The end of the wire is fixed on the pressure plate with a wire clamp; the locking device includes an outer frame, and a locking hydraulic cylinder is fixed on the inner side of the outer frame, and the output shaft is in contact with the pressure plate; the flexible edge-holding system includes a column fixed on the outer frame. There is a blank-holding hydraulic cylinder, the piston of which is attached to the plate through the blank-holding ring, the plate is placed on the press plate, and the oil storage ring groove is embedded in the press plate; the invention can accurately control the forming process in real time, and has the advantages of low cost in mass production , short cycle and good flexibility.

Description

technical field [0001] The invention relates to the technical field of flexible forming, in particular to a thermoplastic material flexible forming device and method. Background technique [0002] Plastic parts are widely used in daily life. Traditional plastic processing and molding methods mainly include extrusion, injection molding, calendering, blow molding, molding, blister, thermoforming, etc., but there are generally high costs for small batch production and high sample trial production costs. , long cycle, poor flexibility and other shortcomings. [0003] Flexible manufacturing is the development trend of the manufacturing industry. Among them, "dieless multi-point forming technology" is an advanced manufacturing technology that integrates flexible forming technology and computer technology, and is a three-dimensional surface digital forming technology for sheet metal. [0004] The application of multi-point forming technology to the flexible forming of thermoplasti...
