Description

Technical Field

[0001] The utility model belongs to the field of processing operations, and in particular relates to a carbon slide plate clamping device. Background Art

[0002] Carbon slide plates are important components of rail transit vehicles such as electric locomotives, EMUs, light rails, and subways. They are installed on pantographs and in direct contact with the contact network. After obtaining current from the contact network wire, they conduct the current to the train and provide electricity. The pantograph slide plate and the contact network wire form a special friction pair with mechanical and electrical coupling. The main failure mode of carbon slide plates is wear to the limit, and they may also have to be replaced due to breakage, falling off, and falling off. Once the carbon slide plate on the train fails, it will seriously endanger driving safety. Therefore, the various performances of the carbon slide plate must meet the design requirements to ensure the stable operation of the electric locomotive.

[0003] During the production process of carbon skateboards for rail vehicles, the aluminum bracket needs to be bonded to the carbon strip to ensure good conductivity and bonding shear strength. Bonding shear strength is related to the shear resistance of the carbon skateboard during operation and is a key performance of the carbon skateboard. During bonding, the carbon strip and the aluminum bracket need to be clamped and then sent to the heat treatment equipment for curing. Utility Model Content
