Plate multipoint forming device with crease resistant functions

Abstract

The invention discloses a plate multipoint forming device with crease resistant functions, relating to plastic processing equipment used for plate curved surface forming and belonging to the field of mechanical engineering. The device mainly comprises shape-adjusting units (1), clamping units (2), a unit fixing plate (4) and a loading mechanism and is characterized in that the shape-adjusting units (1) and the clamping units (2) are arranged in a staggering manner; enveloping surface shapes of the plurality of shape-adjusting units (1) with adjustable heights can be changed through a shape-adjusting mechanism; the traditional entity die is replaced; and the plurality of clamping units (2) which are shifted passively are used for clamping a plate through back pressure effects to replace a side-pressing mechanism. The device can be used for inhibiting creases and rebound when the plate is formed and used for forming complex outline curved surface members with different sizes, therefore, the step of cutting sides after forming is omitted, and the utilization rate of the plate is improved.

Description

technical field [0001] The utility model relates to a board multi-point forming device with anti-wrinkle function, which is used for curved surface plastic processing, and belongs to the field of mechanical engineering. Background technique [0002] At present, the three-dimensional surface forming of sheet metal is mainly realized by integral mold or multi-point digital mold. When forming thin plates or complex-shaped three-dimensional curved parts, edge-holding mechanisms are often required to prevent wrinkling, which leads to complex mold structures, reduces the utilization rate of sheet metal, and requires an additional trimming process after forming. In this way, for traditional overall molds, one or more sets of molds are often required to form a workpiece, which increases mold making costs and mold adjustment time; while for multi-point molds, although multiple regularly arranged, height-adjustable The basic body unit changes the shape of the forming surface to reali...

When forming thin plates or complex-shaped three-dimensional curved parts, edge-holding mechanisms are often required to prevent wrinkling, which leads to complex mold structures and reduces the utilization rate of sheet materials, and additional trimming processes are required after forming

In this way, for traditional overall molds, one or more sets of molds are often required to form a workpiece, which increases mold making costs and mold adjustment time; while for multi-point molds, although multiple regularly arranged, height-adjustable The basic body unit changes the shape of the forming surface to realize the multi-purpose function of one mold and reduce the cost of mold making. However, when forming a small-sized workpiece, it is necessary to use a larger size sheet than the actual required size to realize the blanking
