Embodiment Construction

[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.

[0029] Figure 2 to Figure 7 Together, it shows the thermoforming closing device provided by the embodiment of the present invention, which is used to close the workpiece under high temperature, and can automatically support the inner wall of the workpiece and automatically withdraw the workpiece, effectively ensure the safety of the operator, improve the processing efficiency, and ensure the closing precision.

[0030] exist figure 1 shows a kind of closing change process of the workpiece 2 suitable for the thermoforming closing device, the thickness of the workpiece 2 is 0.8mm, and the material is martensitic stainless steel. Since the material has a large rebound when forming, the shape is not easy Control, in order to control the springback of the workpiece ...

Abstract

The invention discloses a thermal forming closing-in device which comprises a lower die provided with a workpiece mounting groove, an upper die provided with a closing-in inclined plane, a driving seat used for driving the upper die to press downwards and closing in a workpiece in the workpiece mounting groove, a conical guide block and an inner supporting mechanism used for abutting against the inner wall of the workpiece. The inner supporting mechanism comprises a connecting base used for being driven by the driving base to ascend and descend, a plurality of inner supporting blocks connected with the connecting base in a sliding mode and arranged around the conical guide block, and an elastic reset assembly used for pushing the inner supporting blocks to the conical guide block, and the inner supporting blocks are used for being pushed by the conical guide block to be in the state of abutting against the inner wall of the workpiece during descending. According to the thermal forming closing-in device, when the driving base drives the upper die to descend for closing in, the inner supporting mechanism can be synchronously driven to descend, the multiple inner supporting blocks are gradually opened through the guiding effect of the conical guiding block, the inner wall of a workpiece is automatically abutted against before the closing-in procedure, and the closing-in effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of aero-engine sheet metal sheet metal processing, in particular to a thermoforming closing device for aero-engine sheet metal sheet metal processing. Background technique [0002] At present, for the closing process of aero-engine sheet metal and sheet metal workpieces, when the material used for the workpiece is relatively elastic, in order to control springback, the thermoforming method of heating the material or the material and the mold at the same time is usually used for closing, such as heating the workpiece to About 900°C, and then put it into the mold for closing and forming. [0003] However, when the outer wall of the workpiece is squeezed to close, it is also necessary to fill the inner wall of the workpiece with blocks for support. In order to enable the workpiece to be removed from the mold normally, it is necessary to set the blocks into a block-inlaid structure, resulting in the need for ope...
