Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] refer to figure 1 , a fiber-reinforced resin-based composite sheet hot stamping forming device, including die assembly, punch assembly, blank holder and support device, hot oil heating system, mold water spray cooling system, in order to facilitate cooling water in Flow out from the mold under the action of gravity. In the present invention, the mold adopts an inverted form. The die assembly is connected with the slider of the press, and the press drives the die assembly to move downward to realize the stamping action. The punch assembly is installed on the base 2-7, fixed, the center line of the die assembly, the punch assembly and the base 2-7 is the same center line A-A, the blank holder and the supporting device are installed on the base 2-7, surrounding the punch 3 -1 Evenly distributed.

[0026] The die assembly includes a die 1-1, the die 1-1 ...

Abstract

The invention relates to a device and a method for forming a fiber reinforced resin-based composite material plate through hot stamping. The device comprises a female die component, a male die component, a blank holder, a supporting device, a hot oil heating system and a die water spray cooling system, wherein the female die component is connected with a sliding block of a press; the male die component is arranged on a pedestal; and the blank holder and the supporting device are arranged on the pedestal. The forming method comprises the following steps: placing a plate material on the surface of the blank holder; starting the hot oil heating system to heat a female die, a male die and the blank holder to the set temperature; starting the press; driving the female die to move close to and contact with the plate materials; suspending operation; heating the plate material to the softening temperature of a resin matrix through contact heat transfer of the female die, the male die and the blank holder; continuously operating the press; descending a nitrogen cylinder; adjusting the nitrogen cylinder to obtain the proper blank holder force; and gradually forming the plate material. By the device and the method, the fiber reinforced resin-based composite material plate can be formed through hot stamping and formation efficiency and quality are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of composite material forming, and in particular relates to a hot stamping forming device and method for a fiber-reinforced resin-based composite material plate. Background technique [0002] Fiber-reinforced composite materials have excellent properties such as light weight, high specific strength, large specific modulus, high temperature resistance, corrosion resistance, fatigue resistance and good damping performance. As structural parts, they have been widely used in aerospace, automobile manufacturing and other fields. However, due to the complex forming process of traditional composite materials, expensive equipment and long production cycle, it is difficult to meet the large-volume demand for composite structural parts in civilian industries such as automobile manufacturing. Especially in recent years, the country's requirements for structural lightweight, energy saving and emission reduction, how to ...
