Abstract

The invention provides an equipment cabin pultrusion technology. The equipment cabin pultrusion technology comprises the steps that firstly, fiber yarn and fiber fabric are discharged at the same time, an equipment cabin body part is made of fiber fabric, and fiber yarn is adopted at the corner part or the thickened part; secondly, a pre-forming die is used for conducting pre-forming treatment onthe fiber yarn and the fiber fabric, the pre-forming die comprises a plurality of pre-forming plates, the pre-forming plates are provided with hollow grooves, the hollow grooves can gradually change,and finally the product shape is formed; thirdly, glue injection type pultrusion is conducted on the pre-formed fiber yarn and the pre-formed fiber fabric; fourthly, a curing die is used for conducting curing on the fiber yarn and the fiber fabric obtained after pultrusion; and fifthly, an automatic cutting machine is used for cutting the cured fiber yarn and the cured fiber fabric. Compared withthe prior art, the fiber fabric and fiber yarn mixed pultrusion manner is adopted, holes of the fiber fabric are filled, the fiber content reaches up to 80%, and the equipment cabin mass is further reduced.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a pultrusion process for an equipment cabin. Background technique [0002] The equipment cabin is a cabin space located at the bottom of the motor car for placing equipment. Its function is to protect the equipment from the collision and interference of foreign objects such as rain, snow, wind and sand. The acceleration and aerodynamic loads received by the train during operation also act on the equipment cabin. Therefore, the overall structural rationality and strength of the equipment compartment play a vital role in the operation safety of the train. [0003] Traditional equipment compartment brackets are mostly made of aluminum alloy or other metal materials, and the assembly method is welding, which has the disadvantages of heavy weight, high energy consumption for welding, labor-intensive, and high cost. Especially with the speed increase of high-speed rail, it has be...
