AI Technical Summary
Technical Problem
Existing assisted drawing molding devices face challenges in controlling assist pressure effectively, leading to thinning and cracking of materials, especially when molding products with a high ratio of product width to product height, such as aluminum alloy throttle products.
Method used
The assisted drawing molding device incorporates a control system that adjusts assist pressure in real-time based on the position of the punch, using a pair of assist punches and a control device that acquires position and pressure information to maintain target assist pressures.
Benefits of technology
This solution enables the formation of deeper products with a high width-to-height ratio while preventing material thinning and cracking, achieving a simpler and cost-effective configuration.

Abstract
To provide an assist squeezing / molding device that can finely control an assist pressure during assist squeezing / molding, so that localized necking, cracking and the like can be suppressed and a product whose depth is deeper can be molded.SOLUTION: An assist squeezing / molding device 10 moves a punch 13 from a stroke starting-end toward a stroke ending-end in accordance with an instruction to a punch driving part from a control device 200, makes a blank holder 15 press a blank material M against a squeezing / molding die 14, when performing squeezing / molding in cooperation with the squeezing / molding die 14 and also performs assist squeezing / molding while making assist punches 32A and 32B press both end faces of the blank material M. The control device 200 comprises an assist pressure control part that controls the assist punch driving part so that the assist pressure of the assist punches 32A and 32B becomes equal to a target assist pressure corresponding to a position of the punch 13, when performing the assist squeezing / molding.SELECTED DRAWING: Figure 1
