Curved profile pultrusion production traction device and method

Abstract

The invention relates to a pultrusion production traction device and method of fiber reinforced composite material curved profiles. The traction device is provided with a rack platform; a rack is provided with two rows of slide rails distributed in a fan shape; each slide rail is provided with a vertical roller; the rollers can move along the slide rails; the two rows of rollers are arranged alongthe circular curve; two guide blocks are arranged between the rollers; and the guide blocks conduct plane movement along the track formed by the rollers under pushing of a jack. The guide blocks areconnected with a chuck through vertical connection shaft to form a traction portion jointly, the vertical connection shafts can drive the chuck to rotate, and the chuck is composed of an upper clamping board, a lower clamping board and a vertical guide rail. Through plane movement of the guide blocks and the rotation of the vertical connection shafts, the chuck can conduct plane rotation along thecircular curve. At the same time, by moving the two rows of rollers and the rotation speed of the vertical connection shafts, the radius of the circular curve track can be adjusted, and the effect offorming needed curved profiles through various uninterrupted circular curve profiles is achieved. The movement principle is clear, the applied production device is simple and convenient to use, and the pultrusion production traction device and method are suitable for pultrusion production of curved bent profiles of different types.

Description

technical field [0001] The invention relates to a traction device for pultrusion production of curved profiles of fiber-reinforced composite materials, belonging to the field of fiber-reinforced composite material structures. Background technique [0002] The application of steel structures in the field of civil engineering has been quite mature and common, but the shortcomings and deficiencies of this structure are increasingly exposed, such as steel corrosion affecting the durability and later reliability of the structure, and the ultra-high strength of building materials is difficult to achieve. Consumption is non-renewable, etc. For this reason, the engineering community has been seeking a material with ultra-high strength, low density (light weight), and good corrosion resistance to replace steel as structural profiles. Among the many new materials, the most promising is the new material fiber reinforced composite material (full name Fiber Reinforced Plastic or Fiber R...

Problems solved by technology

However, the traditional pultrusion production process is only suitable for the production of linear profiles with different cross-sections. With the gradual promotion of the application of FRP profiles in the field of civil engineering structures, the curved FRP profiles are gradually getting attention, which requires the traditional linear profiles. Based on the improvement of the pultrusion production process, the curved FRP profiles can be produced in the factory, so as to better promote the wider application of FRP profiles
