Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific embodiment:

[0023] control image 3 as well as Figure 4 , an electromagnetic heating type FRP profile pultrusion machine, including a forming die 1, a die fixture 2, an electromagnetic coil 3 and a controller 4, the die fixture 2 includes two clamp bodies 2a, and the forming mold 1 is clamped between the two clamp bodies 2a, There is an extrusion processing space (not shown in the figure) inside the forming mold 1, and three sets of electromagnetic coils 3 are evenly set on the forming mold 1 and the mold fixture 2, corresponding to the three-stage temperature control and connected to the controller 4 respectively. The layer is wrapped with thermally insulating and nonmagnetic ceramic fiber paper (not shown in the figure), and the mold fixture 2 is made of non-metallic polyether ether ketone. Both sides of the molding die 1 are respectively provided with a material inlet 1a and a mat...

Abstract

The invention relates to an electromagnetic heating type pultrusion machine for FRP profiles, which includes a forming die, a die clamp, an electromagnetic coil and a controller. In the middle, the electromagnetic coil is sleeved on the forming mold and the mold fixture and connected to the controller, and the two sides of the forming mold are respectively provided with a material inlet and a material outlet. The present invention uses electromagnetic heating to heat only the mold, which has high thermal efficiency and remarkable energy-saving effect; the electromagnetic coil used in the present invention is subjected to heat insulation treatment, which will not age, and the maintenance cost is greatly reduced; the present invention uses electromagnetic heating, only the mold itself is heated, so It will not affect the equipment itself and the surrounding environment, can effectively reduce the room temperature, and improve the working environment; the heating method adopted in the present invention has a fast heating speed, and can easily control the temperature of the mold by controlling the number of coils or the power supply voltage. The control is simple, flexible and high precision.

Description

technical field [0001] The invention relates to an electromagnetic heating type pultrusion machine for FRP profiles. Background technique [0002] At present, the existing heating devices of FRP profile pultrusion equipment on the market are all heated by traditional electric heating tubes, such as figure 1 as well as figure 2 As shown, the heating is divided into three zones, front (A), middle (B), and rear (C). According to the process requirements, the temperature of each section can be adjusted by itself. The profile raw material enters the mold 6 from the material inlet 7 and is preheated. , heating, and shaping, the product is output from the discharge port 8. [0003] It can be seen that there are many disadvantages in this heating method: [0004] 1. This traditional heating method has a large heat loss, and the heat actually applied to the mold 6 is less than 50% of the heat generated by the heating tube 3, and the rest of the heat (greater than 50%) is dissipat...
