Problems solved by technology

[0003] Existing FRP processing devices have certain disadvantages in use, and cannot realize the integrated operation of FRP winding and pultrusion. Traditional FRP processing devices can only achieve single winding or pultrusion. During the FRP pultrusion process The temperature change is single, there is no preheating function, and the pultrusion molding cannot be well realized. The pultrusion molding processing efficiency is low, which has a certain impact on people's use process. Therefore, we propose a FRP winding molding and pultrusion process

Embodiment 1

[0037] Such as Figure 1-9 As shown, a glass fiber reinforced plastic winding forming and pultrusion process includes steps 1) glass fiber reinforced plastic winding; step 2) preforming; step 3) primary heating pultrusion setting; step 4) secondary heating pultrusion setting.

[0038] Specific steps are as follows:

[0039] Step 1) FRP winding: Install the glass steel wire to be processed on the two sets of shafts (10), clamp one end of the glass steel wire inside the fastening ring (14) with a clamp, and control the control panel to make the No. 1 motor (7) ) Work, the No. 1 motor (7) rotates so that the No. 1 gear (12) drives the hollow gear (13) to rotate. The glass steel wires inside the two sets of fastening rings (14) are wound together to form. After winding for a certain period of time, the two sets of The glass steel wire at the shaft (10) end is cut off;

[0040] Step 2) Pre-forming: Put one end of the glass steel wire cut in step 1) into the silo (28), control the contro...

Abstract

The invention discloses a glass fiber reinforced plastic winding forming and pultrusion process. The method comprises the steps (1) installing a glass steel wire to be machined on two sets of sleeve shafts, wherein one end of the glass steel wire is clamped in a fastening ring through a clamp, a first motor rotates to enable a first gear to drive a hollow gear to rotate, the glass steel wires in the two sets of fastening rings are mutually wound and formed, and the glass steel wires at the ends of the two sets of sleeve shafts are cut off; 2) backwards extruding and conveying the wound glass steel wires to realize preforming; (3) carrying out primary heating pultrusion shaping, (4) carrying out secondary heating pultrusion shaping after carrying out primary pultrusion shaping on the glasssteel wires subjected to primary pultrusion shaping, and carrying out pultrusion on the glass steel wires subjected to secondary heating pultrusion shaping to sequentially realize primary heating pultrusion shaping and secondary heating pultrusion shaping so as to meet pultrusion shaping.

Description

Technical field [0001] The invention relates to the field of glass fiber reinforced plastic processing, in particular to a glass fiber reinforced plastic winding forming and pultrusion process. Background technique [0002] Glass fiber reinforced plastic (FRP) is also called GFRP, that is, fiber reinforced plastic, generally refers to the use of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, glass fiber or its products as a reinforced plastic, called glass fiber Reinforced plastic, or glass fiber reinforced plastic, is different from tempered glass. FRP products are mostly processed by winding and pultrusion during the production process. The pultrusion process is to impregnate a continuous twistless roving, felt, tape or cloth with glue. Under the action of traction, heating and pultrusion forming and curing of molds are used to continuously produce FRP profiles with unlimited length. The pultrusion process is a special process in the FRP f...
