Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass fiber reinforced plastic production, in particular to the technical field of a glass fiber reinforced plastic internal heating and curing device. Background Art
[0002] In the production of FRP, after FRP is formed in the mold, it needs to be cured to a certain strength before demoulding. The curing of resin is greatly affected by temperature. In order to save costs, the product is often cured at room temperature, which leads to slow curing speed and low production efficiency. At the same time, it also has a great impact on product strength, especially in winter when the workshop temperature is often below 15℃.
[0003] At present, most of the heating methods used are external baking. The curing order of the products is from the outside to the inside. When the FRP products are cured, the adhesive will shrink in volume. If the gel on the outside of the product is cured first, the adhesive inside will flow outward, causing the internal fibers to fail and cause defects. Since the curing of FRP is an irreversible reaction, strict control of the curing order and direction is crucial to improving product quality and reducing the risk of defects, especially for large cylindrical FRP products, which are always in a rotating state during production. Curing them has always been a difficult technical problem to solve. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a glass fiber reinforced plastic internal heating and curing device, which realizes heating inside the mold, especially inside the large rotating glass fiber reinforced plastic product, so that the product is cured from the inside to the outside, which can effectively reduce the defects of glass fiber reinforced plastic curing.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A tempered glass fiber reinforced plastic internal heating and curing device comprises a shaft, a fixed wheel and a heating lamp, wherein the fixed wheels are fixedly mounted on both sides of the shaft respectively, and rotating wheels are rotatably mounted on both sides of the shaft, and the rotating wheels are located on the inner side of the fixed wheels. A mounting frame is fixedly mounted on the shaft, the heating lamp is fixedly mounted below the mounting frame, and a wiring bracket is fixedly mounted on the mounting frame.
[0007] Preferably, the mounting frames and the heating lamps are arranged in a row on the axis, and wiring tubes are fixedly installed between the mounting frames arranged in a row, and wires are inserted into the wiring tubes, and both ends of the wires are electrically connected to the heating lamps respectively.
[0008] Preferably, a counterweight is fixedly mounted on the mounting frame.
[0009] Preferably, a wiring socket is provided at the upper end of the wiring bracket, and the wiring socket is electrically connected to the baking lamp.
[0010] The beneficial effects that can be achieved by the utility model using the above technical solution are:
[0011] 1. By rotating wheels installed on both sides of the shaft, and mounting frames and heating lamps fixedly installed on the shaft, the device is placed in a large cylindrical FRP product. When the large cylindrical FRP product rotates, the device, under the gravity of the mounting frame, heating lamp and counterweight, keeps the heating lamp in a downward position all the time, so that the FRP product is heated from the inside to the outside, and the curing sequence is more in line with the design requirements;
[0012] 2. By fixing fixed wheels on both sides of the shaft, when the device rolls inside the cylinder, the fixed wheels remain relatively still under the action of the heating lamp and the counterweight. When several groups of the devices are required to work together, the fixed wheels of two adjacent groups of the devices are in contact and remain relatively still, avoiding the possibility of interference between the two adjacent groups of the devices.
