AI Technical Summary

Benefits of technology

This technology combines both blanking/laying with heat treatment (taping) to improve productivity while reducing costs compared to conventional methods such as casting or die forming. It also allows for more flexibility when designing different types of laminated elastic materials that require specific properties like compression force at room temperature. Overall, this new combination improves manufacturing efficacy by making it faster and easier to produce various products from these materials.

Problems solved by technology

This patented method for producing complex laminated elastic structures involves multiple steps that require significant effort or equipment investment during each step. These technical problem addressed through this patents includes lower productivity due to slow manufacturing times caused by current methods such as cutting up layers from large sheets beforehand, placing them onto smaller forms manually with less than 10 minutes per hour, and waiting at room temperature until they cure properly.

Abstract

The invention belongs to the technical field of preparation of resin matrix composite materials and relates to a production process method for die pressing composite material leaf springs. The production process method comprises the following production steps: a, blanking: laying prepreg on a laying die and then cutting the prepreg to form a whole blank; b, cutting the whole blank: cutting the whole blank along the length direction of the leaf springs to form a plurality of single blanks, wherein the width of single blank is that of each leaf spring; c, moulding: putting cut single blanks intoa performing mold for in-advance compaction to form preformed leaf springs; d, preheating a baking oven: sequentially putting the preformed leaf springs into the baking oven, and heating to predetermined temperature required by the process; e, die pressing and curing: putting the preformed leaf springs heated to the predetermined temperature into a pressing machine for heating, pressurizing and curing; f, demolding: removing the cured leaf springs from the die. According to a process method disclosed by the invention, the time for producing one leaf spring can be shortened within 30 minutes.The batch production of the leaf springs can be realized.
