[0002] As train speeds increase, how to safely stop high-speed trains is an important issue related to the safety of life and property. Train braking includes resistance braking, magnetic rail braking, eddy current braking, friction braking and other methods, among which friction braking is indispensable.

[0003] Powder metallurgy brake pads can be divided into two types according to the type of brake caliper: dovetail type powder metallurgy brake pads and non-dovetail type powder metallurgy brake pads. Figure 1 and Figure 2 The figure shows an existing dovetail type powder metallurgy brake pad, which includes a steel back, a friction body fixedly mounted on the front of the steel back, and a dovetail plate fixedly mounted on the back of the steel back.

[0035] Embodiment 2:

[0036] like Figures 8 to 10 As shown, the difference between this embodiment and the first embodiment is that the paint spraying assembly includes a second spray gun rod 31, the second spray gun rod 31 is arranged horizontally front and back perpendicular to the moving direction of the stand 2, and a second spray gun 32 arranged downward is fixedly installed at the front end of the second spray gun rod 31; a rotary damper 33 is installed on the top rear side of the spray gun bracket 13, and the rotary damper 33 is provided with a first rotating part 34 and a second rotating part 35 which can rotate relatively, and the first rotating part 34 is fixedly installed on the spray gun bracket 13 by screws, and the second spray gun rod 31 passes through the first rotating part 34, the second rotating part 35 and the spray gun bracket 13, and the second The spray gun rod 31 is fixedly mounted on the second rotating part 35 by screws, and the axis of rotation of the second rotating part 35 coincides with the axis of the second spray gun rod 31; two ejector pins 36 are relatively fixedly mounted on the bottom plate 1 along the moving direction of the stand 2, specifically, ejector pin brackets 37 are respectively fixedly mounted on the two walking track template brackets 16 by bolts, and ejector pins 36 are respectively embedded in the two ejector pin brackets 37; a swing plate 38 is fixedly mounted on the rear end of the second spray gun rod 31, and a through hole is provided at one end of the swing plate 38, and the rear end of the second spray gun rod 31 is embedded in the through hole, and the swing plate 38 is located between the two ejector pins 36.

[0037] The swing plate 38 is biased to one side of the second spray gun rod 31. When there is no external force, the second spray gun 32 remains in a downward setting state, and the swing plate 38 is also biased to the bottom of the second spray gun rod 31; during the painting process, when the stand 2 moves left and right to drive the second spray gun to move to the top of the left or right end of the powder metallurgy gate 39, the swing plate 38 collides with the ejector pin 36 on the corresponding side, and then the ejector pin 36 reacts to the swing plate 38 and causes the swing plate 38 and the second spray gun rod 31 to rotate. The second spray gun rod 31 drives the lower end of the second spray gun 32 to rotate inward by a certain angle, so that the paint spraying mask of the second spray gun 32 always falls on the top of the powder metallurgy gate 39. When the ejector pin 36 acts on the swing plate 38 to rotate the second spray gun rod 31, the second spray gun rod 31 drives the second rotating part 35 to rotate relative to the first rotating part 34, so that the rotary damper 33 stores energy; when the swing plate 38 is separated from the ejector pin 36, the energy of the rotary damper 33 is released and the second spray gun rod 31 and the second rotating part 35 rotate in the opposite direction, so that the angle of the second spray gun 32 is reset, and the second spray gun 32 returns to the downward setting state.
