Heating and curing device for drawing and winding production of composite material

Abstract

The invention discloses a heating and curing device for composite material drawing and winding production, which comprises a plurality of drying ovens arranged along the bar drawing and winding feeding direction, and a preset distance is arranged between every two adjacent drying ovens so as to prolong the bar heating and curing time; each drying oven comprises an oven body, a heating pipe arranged in the oven body and used for heating the bar, and an intelligent temperature control system in signal connection with the control end of the heating pipe and used for correspondingly adjusting the heating temperature of the heating pipe in the oven body according to the heating curing stroke of the bar. Thus, by means of discontinuous arrangement of the multiple drying ovens, the heating and curing stroke and time of the bar are effectively improved, meanwhile, the intelligent temperature control system is used for independently controlling the temperature of the heating pipes in the drying ovens, and the influence of the spacing distance between every two adjacent drying ovens on the temperature of the bar is eliminated; therefore, the internal temperature is easy to control and tends to be average, the bar heating uniformity can be improved, and the forming quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of stretch-wrap forming technology, in particular to a heating and curing device for stretch-wrap production of composite materials. Background technique [0002] The composite material drawing and winding process refers to the method of making pultrusion products through the processes of threading, dipping, winding, curing and shaping, cutting and other processes under the traction of external force. Curing and setting is the key process, which has a direct impact on the mechanical properties and appearance of the product. [0003] At present, in the curing and setting process in the composite material stretching process, the heating and curing device commonly used is a continuous oven. Cover the entire bar. At the same time, heating components such as electric heating wires of equal length or slightly shorter are installed in the oven to continuously heat the bar during the drawing and feeding process, s...

Problems solved by technology

[0004] However, although the overall long oven structure in the prior art can directly cover the entire heating and curing process of the bar, the temperature distribution in the length direction of the oven is not uniform due to the excessively large length of the oven structure. In the case of high-speed production, the feeding speed of the bar is fast, the heating and curing time is short, and the heating of the bar is uneven, which easily affects the molding quality, and even the quality of the bar is not qualified due to incomplete curing and bending.
