Description

Technical Field

[0001] The utility model relates to the technical field of pultrusion dies, in particular to a preforming die carrier for composite material pultrusion dies. Background Art

[0002] In the fields of automotive, construction, energy, industry, and transportation industries, material solutions are gradually changing, that is, from traditional materials to high-performance composite materials, which provides market opportunities for the rapid popularization and use of high-performance composite materials.

[0003] Due to the fully automated control of the production process of composite material pultruded profiles, they have the advantages of high production efficiency and good quality uniformity. Therefore, more and more profiles are produced by the pultrusion process. However, during the pultrusion production process, due to factors such as die blockage and regular maintenance, the pultrusion die and the preforming die carrier need to be repeatedly disassembled and assembled. However, due to the large gap in bolt connection, the repeated installation position accuracy of the pultrusion die and the preforming die carrier is poor. After each die cleaning, the preforming die carrier needs to be repeatedly adjusted, which affects the straightness of the product, product quality, and production efficiency.

[0004] Therefore, how to provide a preforming die carrier for composite material pultrusion dies to improve the repeated positioning accuracy of the pultrusion die and the preforming die carrier has become an urgent technical problem to be solved. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a preforming die carrier for composite material pultrusion dies to improve the repeated positioning accuracy of the pultrusion die and the preforming die carrier.

[0006] The utility model is realized as follows: A preforming die carrier for composite material pultrusion dies, comprising:

[0007] A preforming die carrier body with clearance fit with the pultrusion die, provided with four long rods, several short rods, two flat plates, and several bolts; the long rods are parallel to each other, and the short rods are connected to the long rods by bolts, so that the four long rods enclose a rectangle; the two flat plates are respectively arranged on the left sides of the upper two long rods and the lower two long rods by bolts; two positioning holes are provided in the middle of each flat plate;

[0008] Four positioning pins are respectively arranged in one of the positioning holes.

[0009] Further, the positioning pins are internal thread positioning pins.

[0010] Further, the clearance allowance between the preforming die carrier body and the pultrusion die is 0.05 mm.

[0011] The advantages of the utility model are as follows:

[0012] By respectively arranging two positioning holes on the upper and lower flat plates of the preformed die carrier body, and respectively arranging an internal-thread positioning pin for positioning the pultrusion die in each positioning hole, since the preformed die carrier body and the pultrusion die are in clearance fit with a clearance allowance of 0.05 mm, combined with the limitation of the internal-thread positioning pin, the degrees of freedom of the pultrusion die and the preformed die carrier body can be effectively restricted, thereby greatly improving the repeat positioning accuracy of the pultrusion die and the preformed die carrier body, and ensuring the straightness of the product, the product quality and the production efficiency.
