Huoluo hemisphere type pressure head base body of multi-pressure-head sheet forming device

Abstract

The invention relates to a detachable hemisphere type base body of multiple pressure head board forming device, including a pillar (8), a pressure head (6); one end of the pillar (8) connects to the frame, the other end connects to the pressure head (6); the pressure head (6) is hemispheroid, the working face of the pressure head (6) is plane; a concave sphere support seat (7) is provided between the pillar (8) and the pressure head (6), the sphere portion of the pressure head (6) detachable connects to the concave sphere support seat (7). The pressure head (6) of the base body is not easy to incline when working, the pressing board surface is smooth with little impression.

Description

technical field [0001] The present invention relates to forming processing equipment for large-scale three-dimensional curved plate components, in particular to a multi-press plate forming device, such as a forming processing equipment for hull panels with arbitrary curved shapes, especially the basic body of the multi-press plate forming device. Background technique [0002] For some plate components that need to be pressed and formed by an integral mold, multi-head plate forming devices have been used to replace expensive mold processing, such as the multi-point plate forming press developed in China. Existing multi-head plate forming device includes: a movable upper frame, a plurality of upper basic bodies connected with the upper frame, a lower frame, and a plurality of lower basic bodies connected with the lower frame; each basic body includes a pillar, a pressure head , the pillar is connected with the frame, and the indenter is connected with the pillar.

Problems solved by technology

[0004] The multi-indenter plate forming device with a convex working surface of the indenter, also known as a multi-point plate forming device, has the disadvantage of its basic body: because the indenter mold is in a convex shape, when the mold and the plate are pressed and formed, the indenter and the plate The plate is in point contact. At this time, the concentrated force is easy to cause indentation on the plate; in addition, when processing curved plates, when some parts of the plate are inclined (as shown in Figure 9), the working surface of the indenter is convex. , the contact point between the upper basic body indenter 6 and the plate 18 and the contact point between the lower basic body indenter 6 and the plate 18 are not at the same point, and it is easy to cause local concave-convex indentation deformation of the plate 18, so it is difficult to meet the needs of large-scale hulls. Shipbuilding quality requirements for smooth outer plates and small indentations

The disadvantages of this basic body are: 1. Due to the high center of gravity, the indenter is prone to be in an unstable state, that is, the indenter is always inclined; Complicate adjustment control and cause inconvenience
