Embodiment Construction

[0018] Such as figure 1 , figure 2 and image 3 The upper part of the shot blasting device in the illustrated embodiment is provided with a horizontal rail 2, which can bear the load caused by the suspension of the workpiece W. The track 2 extends from above a working area S where the workpiece W is wound on and released from a chain sling 1 to above an enclosure B. The enclosure B defines a projection chamber 5 .

[0019] The track 2 is provided with two lifts 3 (vertical moving devices) that can move along the track 2 , and the lifts 3 can also move vertically through, for example, steel wires 31 . Suspended on each wire 31 of each elevator 3 is a reversing machine 4 . The reversing machine 4 includes a chain sling 1 , an annular member formed by end-to-end chains, and a sending mechanism for sending out the chain sling 31 . The length of the chain sling 1 is such that it can at least partially wrap around the circumference of the workpiece W. When both ends of the wo...

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 movedalong 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.

Description

technical field [0001] The invention relates to a shot blasting device, in particular to a shot blasting device suitable for processing large metal products. Background technique [0002] Japanese Patent No. 9-047966 owned by the assignee of the present application discloses a conventional shot blasting apparatus for processing large metal products as workpieces, which apparatus has a turntable. In this apparatus, the workpiece is placed on a turntable so as to be rotated so as to be polished. [0003] However, in this shot blasting device with a turntable, when a large metal product is to be polished, since the workpiece is located on the turntable, the turntable will cause blind spots in the projection toward the workpiece (for example, the bottom surface of the workpiece, or the workpiece falls within the shadow of the turntable itself). Therefore, it is not possible to completely polish the entire surface of the workpiece to be treated. In particular, if the workpiece...
