[0039] To solve the defects in the prior art, the present application provides a brake clamp hanger processing device for automatically processing brake clamp hangers in batches. The brake clamp hanger is composed of thermoplastic fiber reinforced composite material, so that the brake clamp hanger has the characteristics of lightweight, corrosion resistance and fatigue resistance.

Among them, the brake clamp hanger 200 is composed of thermoplastic fiber reinforced composite material.

[0044] As shown in Figure 1 and Figure 2 , when processing the main body structure 13 of the brake clamp hanger 200, the inner side of the connecting handle 204 (i.e. the side away from the brake disc when the brake clamp hanger 200 is installed on the EMU train) is placed on the hot bending die 11, the upper layer plate 202 and the lower layer plate 203 are respectively clamped on the side of the hot bending die 11, the pressing tool 102 is attached to the outer side of the connecting handle 204 (i.e. the side close to the brake disc when the brake clamp hanger 200 is installed on the EMU train), and the first bending tool 101 and the second bending tool 103 are pressed to be attached to the surface of the lower layer plate 203 and the upper layer plate 202 respectively.
