Abstract:
A method of manufacturing a vehicle suspension component, such as a helical coil spring, includes the step of rotating a first impeller to project ceramic peening media in a first direction toward the vehicle suspension component to peen a surface section of the vehicle suspension component. In one example, the vehicle suspension component is peened with metal peening media before peening with the ceramic peening media. The resulting component has a surface section with a surface section with a surface roughness of /less than 0,025 micrometers.
Abstract:
A shot-blasting machine for shot blasting a workpiece is disclosed. The shot-blasting machine comprises a rail 2 mounted on an upper part of the shot-blasting machine and extending in a horizontal direction, one or two hoists movable along the rail, and two inverting mechanisms 4. Each inverting mechanism 4 includes chain slings 1 for supporting one workpiece W at one end or the other end such that the workpiece W is suspended therefrom and includes a feeder for feeding the chain sling 1. An enclosure B in the shot-blasting machine has an entrance at one side and defines a projecting chamber 5 therein. The upper surface of the enclosure B is provided with an elongated opening 51. The volume of the projecting chamber 5 is to allow the workpiece W supported by the chain slings 1 to be moved along the direction that the rail 2 extends by running the hoist 3, while the workpiece W can be rotated about a rotating axis that is parallel to the direction that the rail 2 extends. The upper surface of the enclosure B is provided with a sealing mechanism 6 for preventing the shots from dispersing from the opening 51 by closing the opening 51 in which the chain slings 1 are inserted.
Abstract:
The present invention aims to provide a shot-treatment apparatus which allows a high throughput of workpieces with the least possible idle time while achieving a uniform shot-treatment effect on workpieces. The shot-treatment apparatus of the present invention has a rotatable main table 30 located in the place where both a projection area to be projected upon by the shot from a projecting device and a non-projection area are included. A plurality of satellite tables 32 for placing workpieces 12 are rotatably mounted on the main table 30. Each satellite table 32 has a driven shaft 33 which is in parallel with a main shaft 31 of the main table 30. The shot is projected from the projecting device against the workpiece 12 that is placed on the satellite table 32. The workpiece 12 that is placed on the satellite table 32 is held down by a holding member 48 of a holding assembly 46. The holding member 48 rotates along with the workpiece 12.
Abstract:
An apparatus for stress shot peening of a coil spring is disclosed. The apparatus of the present invention is constructed such that coil springs, which are compressed and clamped by corresponding spring clamping units (20) facing each other, are rotated on their own axes and are simultaneously supplied into the shot room (10) for shot peening. Therefore, the present invention can markedly enhance the internal stress of the coil spring, compared to a coil spring treated by the conventional shot peening apparatus. Furthermore, in the present invention, because the coil springs are clamped by the corresponding spring clamping units facing each other and are simultaneously rotated and moved into the shot room for shot peening, various kinds of side load coil springs, as well as a typical cylindrical coil spring, can be evenly treated throughout the entire surface thereof by shot peening.
