Flexible die mechanism for sheet metal pre-deformation

Abstract

The invention relates to a flexible mold pressing mechanism for plate predeformation. The flexible mold pressing mechanism comprises a support frame and pressing head components; the support frame consists of two roller way plates symmetrically arranged, and a cushion plate; the roller way plates take the shape of channel steel; notches of the two roller way plates are opposite; rollers are uniformly distributed in each roller way plate in the length direction; the cushion plate is a strip plate, is arranged in the two roller way plates in the length direction, and is positioned above the rollers; the top surface of the cushion plate is connected with channel steel upper flat plates of the two roller way plates; the pressing head components include slide frames and mold heads; the longitudinal sections of the slide frames are I-shaped; the mold heads take the shape of rectangular blocks, and are transversely connected to the bottom surfaces of the slide frames; more than one pressing head components are matched and mounted in the support frame; the slide frames of the pressing head components can move along the rollers; and the mold heads of the pressing head components are positioned below the support frame. The distance of the pressing head components is adjustable to realize predeformation treatment of plates with different lengths.

Description

Technical field [0001] The invention belongs to the field of welding auxiliary tools, and in particular relates to a flexible die mechanism for pre-deformation of sheet materials. Background technique [0002] At present, people often use the anti-deformation method to prevent the deformation of the sheet metal during welding, that is, first estimate the direction and size of the welding deformation of the sheet metal structure, and give the sheet material a deformation in the opposite direction before welding to make it comparable to the deformation after welding. Offset, so that the structural parts after welding maintain the design requirements. [0003] The pre-deformation of the plate material before welding can be completed by the die mechanism installed on the cylinder table of the press. In view of the pre-deformation of plates of different lengths, existing people use a rigid die mechanism. There are several sets of die heads on the rigid die mechanism, but the distance b...
