Device and method for on-line rapid calibration of composite material pultruded profile

Abstract

The invention provides a device and a method for on-line rapid calibration of a composite material pultruded profile. The device comprises a horizontal limiting device and a longitudinal limiting device; the horizontal limiting device comprises a left supporting plate, a right supporting plate, and more than two rollers I which are horizontally and oppositely arranged in parallel; the left supporting plate and the right supporting plate are each provided with a longitudinal strip-shaped hole; the two ends of each roller respectively pass through the strip-shaped holes and are fixed by nuts I; the longitudinal limiting device comprises an upper supporting plate, a lower supporting plate, and more than two rollers II which are longitudinally and oppositely arranged in parallel; the upper supporting plate and the lower supporting plate are each provided with a horizontal strip-shaped hole; the two ends of each roller II respectively pass through the horizontal strip-shaped holes and are fixed by nuts II. According to the device, two limiting devices are used for adjusting the angle of the center line of the profile and the towing center line, and the profile which is about to be cured and demolded is applied with an external force in a certain direction in order to counteract flexural deformation caused by reasons such as residual thermal stress during a curing process of the composite material profile, so the aim of calibrating the profile is realized.

Description

technical field [0001] The invention relates to an online rapid calibration device and method for pultrusion profiles of composite materials. Background technique [0002] At present, during the production process of composite pultruded profiles, bending deformation is caused by curing residual thermal stress and other reasons, which seriously affects product quality and product qualification rate, and increases production costs. At present, the commonly used devices and methods for calibrating profiles mainly include adjusting local fiber tension and adjusting molds, etc., but there are problems that the operation is cumbersome and the desired effect cannot be achieved. [0003] The above problems should be considered and solved in the process of profile calibration. Contents of the invention [0004] The purpose of the present invention is to provide a composite material pultrusion profile online rapid calibration device and method, to solve the calibration profile devi...
