Problems solved by technology

[0003] The traditional method of forming large-sized U-shaped structural parts is pultrusion molding. The advantage of pultrusion molding method is that it can be produced continuously, but there are other problems: because pultrusion molding uses glass fiber filaments impregnated with resin glue, and then solidified and formed , because the lateral bonding force is mainly provided by the resin adhesive, the shear strength of the parallel layer of the structural part is not ideal due to pultrusion

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0020] Such as figure 1 Shown is a schematic cross-sectional view of a trapezoidal large-size U-shaped piece. The trapezoidal large-size U-shaped piece is a U-shaped groove structure in cross section, the cross-section of the large-size U-shaped groove is an isosceles trapezoid, and the width of the opening of the large-sized U-shaped piece is larger than the bottom. The width of the sides. In actual production, the structure of the mold can be changed according to the demand, and then the shape of the large-size U-shaped part can be changed.

[0021] Such as figure 2 Shown is a schematic cross-sectional view of a rectangular large-size U-shaped piece. The rectangular large-size U-shaped piece is a U-shaped groove st...

Abstract

The invention discloses a device for manufacturing a large-size U-shaped part. As a hot pressing forming process is adopted, tension of the large-size U-shaped part in a traditional pultrusion process is avoided, and the parallel layer direction shearing strength of the large-size U-shaped part meets the requirement. As a sliding block spliced structure is adopted, the top, the left side and the right side of the large-size U-shaped part are stressed simultaneously during the mould pressing forming process; the stress on all the surfaces is gradually increased, so that the forming process requirements of thermosetting compound materials are met. Meanwhile, automatic demoulding of products is achieved, and the obtained products are stable and uniform in size and consistent in appearance color.

Description

technical field [0001] The invention relates to the technical field of forming non-planar thermosetting composite materials, in particular to a device for manufacturing large-sized U-shaped parts. Background technique [0002] In UHV power transmission and transformation projects, electrical engineering, construction, and other fields, thermosetting composite structural parts are more and more widely used, and they mainly play the role of supporting and bearing loads. Due to the harsh application environment, higher requirements are put forward for the mechanical properties of its products. [0003] The traditional method of forming large-sized U-shaped structural parts is pultrusion molding. The advantage of pultrusion molding method is that it can be produced continuously, but there are other problems: because pultrusion molding uses glass fiber filaments impregnated with resin glue, and then solidified and formed , because the lateral bonding force is mainly provided by ...
