Local loading forming method for single-action press and combined die

Abstract

The invention discloses a local loading forming method for a single-action press machine and a combined die thereof. The forming method comprises the following steps: firstly, a load is applied to anarea, corresponding to a heightened lower die I, in a combined lower die; secondly, a cushion block is removed, the lower die I moves downwards, and then the upper surface of the lower die I and the upper surface of the lower die II are located at the same horizontal position; and finally, a load is applied to an area corresponding to the lower die II. The die comprises a combined lower die, an upper die, a cushion block and a lock catch, wherein the lower die is composed of a lower die I and a lower die II, and the lower die I and the lower die II are connected through the lock catch; the cushion block is placed on the lower surface of the lower die I, so that the upper surface of the lower die I is higher than that of the lower die II. By means of the local loading forming method, the forming load of the overall complex-shaped component can be effectively reduced, and the forming capacity of press equipment in industrial production is improved; fixed connection of combined dies in different loading areas is achieved in the local loading forming process through a lock catch connection method.

Description

technical field [0001] The invention relates to a hot forging forming process in the field of metal forming, in particular to a forming method and a combined mold for realizing a partial loading process on a single-action press, and further realizing the forming and manufacturing of an overall complex-shaped component under the condition of labor-saving loading. Background technique [0002] Aerospace components increasingly require large-scale integration, thin-walled lightweight, complex, and increasingly demanding performance requirements. The use of high-performance lightweight alloy materials (such as titanium alloys) and lightweight structures (such as thin-walled, monolithic, and ribbed structures) is an effective way to improve the performance and reliability of parts and achieve lightweight equipment. However, light-weight and high-strength materials have high deformation resistance, poor plasticity, and narrow processing window, so they are hard-to-deform materials...

Problems solved by technology

In the combined lower die connection method used for single-action presses, fasteners are mostly used for fixed connection. During local loading, this method may cause gaps between the combined dies, or even separation from each other, resulting in the formation of formed components. defect
