Problems solved by technology

[0004] At present, the wheel set manufacturing process used by high-speed EMU trains at home and abroad is mainly cast steel and rolled steel wheels. In the subsequent heat treatment, machining and other processes, shot peening technology is not used to strengthen the contact surface between the wheel set and the rail. (tread) to strengthen

Embodiment Construction

[0036] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0037] Such as Figure 1-8 As shown, this embodiment discloses a rotary double-station high-speed train wheel shot peening machine, including a shot blasting chamber 1, a shot blaster 2, a shot separation and recovery device 3, a dust removal device 4, a rotary table 5 and a fixture Workbench6. One side of the shot blasting chamber 1 is provided with an observation port 11, so that the shot peening effect can be understood in time without stopping the vehicle during the shot peening process. A workpiece inlet is provided on a side adjacent to the viewing port 11 .

[0038] The rotary table 5 includes a power shaft 51 and a bearing seat 52, the power shaft 51 is installed on the bearing seat 52, and the bearing seat 52 is fixed on the foundation with anchor bolts 53, and there is a certain gap with the foundation. The motor 54 is instal...

Abstract

The invention discloses a shot peening strengthening device for a high-speed train wheel. The shot peening strengthening device comprises a shot-blast room, three shot blasters, a shot separation and recovery device, a shot storage and supply device, a dust removal device, a rotary worktable and a clamp, wherein the rotary worktable is positioned on one side of the shot-blast room and provided with two clamp worktables symmetrically arranged along the diameter; each clamp worktable can be equipped with six train wheel workpieces and rotates in a shot-blast process for strengthening the train wheel surface to be uniform; the rotary worktable can intermittently rotate and rotate 180 degrees each time; the three shot blasters are connected with six blast guns, and each blast gun corresponds to one train wheel workpiece; the shot separation and recovery device comprises a shot lifting machine and a shot separator, and is used for lifting and separating shots; the dust removal device is a dust remover, and the air suction hole of the dust removal device is connected with the shot separator and an air suction hole in the top end of the shot-blast room to guarantee indoor visibility and keep a certain negative pressure in the room. A shot-blast machine is high in processing efficiency and reliable in working.

Description

technical field [0001] The invention relates to the technical field of metal surface strengthening, in particular to a shot peening device for high-speed train wheels. Background technique [0002] The basic principle of shot peening technology is that compressed air is used as the power, and metal abrasives such as cast steel sand, cast steel shot, zinc shot are used as projectiles, and they hit the surface of the workpiece at a high speed, so that the metal surface is plastically deformed (at the same time accompanied by elasticity). Deformation), forming a certain thickness of compressive stress layer on the metal surface, thereby improving the fatigue resistance of parts and prolonging the service life of parts, and greatly improving the surface state of parts, thereby greatly improving the adsorption effect of spraying , improve the corrosion resistance of parts and save a lot of steel. [0003] Compared with ordinary wheels, the biggest difference between high-speed r...
