Description
Technical Field
The invention belongs to the field of equal-curvature section pultrusion production equipment, and particularly relates to a pultrusion production line for equal-curvature sections.
Background
The pultrusion is to perform pultrusion on the composite material through a pultrusion die, and then to pull the pultruded profile through a pulling device, so as to be convenient for subsequent cutting treatment on the profile. During the production of pultrusion processes, it is often involved in the production of curved profiles, such as rear bumper beams for automobiles. When the arc-shaped section is subjected to pultrusion production, the arc-shaped section is clamped by the clamping blocks and then moves forwards, and when the arc-shaped section reaches a specified position, the clamping blocks are loosened, so that the traction of the section is realized. However, since the arc-shaped section has a certain radian, the traction is only carried out by clamping one end of the arc-shaped section, and the other arc-shaped section segments may have a certain drop due to no supporting point or clamping force point, which will affect the production quality of the arc-shaped section.
