Embodiment Construction

[0014] Such as Figure 1 to Figure 4 As shown, a flexible hydraulic jaw is provided with a double-acting hydraulic cylinder in the middle of the clamp body 1, and the top end of the double-acting hydraulic cylinder piston 8 is movably connected to two symmetrically distributed guide rails 14 through a top block 9. The inner side of the guide rail 14 is provided with a wedge-shaped sliding block 12, and the inner side of the sliding block 12 is provided with a clamping washer 13, and the clamp body 1 is connected with a wedge-shaped fixed block 10 through a flat key 11, and the inclined surface of the fixed block 10 is connected with The inclined surfaces of the slider 12 are matched; the front and rear surfaces of the clamp body 1 are respectively provided with two parallel lugs 17, and a pin 15 is provided between the two lugs 17 on the rear surface. When a plurality of clamp bodies 1 are connected, the tabs 17 on the front surface and the tabs 17 on the back surface of the pr...

Abstract

The invention relates to a flexible hydraulic jaw. A double-acting hydraulic cylinder is arranged in the middle of a clamp body; the top end of a piston of the double-acting hydraulic cylinder is movably connected with two symmetrically distributed guide rails through an ejector block; the inner sides of the two guide rails are provided with wedged sliding blocks respectively; clamping pads are arranged on the inner side surfaces of the sliding blocks; the clamp body is connected with wedged fixing blocks through flat keys; the inclined surfaces of the fixing blocks are matched with the inclined surfaces of the sliding blocks; two parallel lugs are arranged on the front surface and the rear surface of the clamp body respectively; and a pin shaft is arranged between the two lugs on the rear surface. The flexible hydraulic jaw can be adjusted into shapes such as a linear shape, a curved shape and the like according to the shape of the section of a part on the basis of a stretching molding requirement, and has stretching molding functions of skin parts with stretching molding reverse curvatures and large curvature radiuses, and large-section profile parts.

Description

Technical field [0001] The invention relates to a flexible hydraulic jaw, which is used for clamping and fixing parts during skin stretching and forming, and is installed on a skin stretching machine. Background technique [0002] The hydraulic jaw is a key component of the skin stretching machine. Its function is to clamp and fix the sheet metal parts, and realize the stretching and forming of the sheet metal parts through various actions of the stretching machine. Double-curvature skin parts are generally stretched, that is, the two ends of the sheet are clamped under the hydraulic jaws of the stretching machine, and the sheet is contacted by the drawing die lifted by the worktable, resulting in uneven plane tensile strain. The sheet is deformed. With the development of anti-aircraft technology, there are more and more large-scale integral skin-like structural parts with different curvatures. The original hydraulic jaws can no longer meet the needs of skin processing. Summary...
