Circulating eccentric shaft type two-stage transmission high-speed precise warm die forging machine

Abstract

The invention relates to the technical field of hot die forging machine devices, and discloses a circulating eccentric shaft type two-stage transmission high-speed precise warm die forging machine which comprises a mounting shell, and a reverse assembly used for driving an upper die table and a lower die table to always keep reverse movement is arranged in the mounting shell. Wedging sliding tables matched with the two chamfers are further arranged in the mounting shell, and the bottoms of the two wedging sliding tables are fixedly connected to the mounting shell through corresponding supporting springs. The upper die table and the lower die table are close to each other or far away from each other, compared with a one-way casting extrusion mode of a traditional upper die table, a blank is placed on the lower die table, synchronous movement of the upper die table and the lower die table is matched, the forming rate of hot die forging can be increased, the time needed by unit casting times is effectively shortened, and economic benefits are improved; and supporting force can be provided for the lower die table, the tension effect borne by the fastening nut is reduced, the service life of the fastening nut is prolonged, and the practicability of the whole die forging machine is improved.

Description

technical field [0001] The invention relates to the technical field of hot die forging machines, in particular to a circulating eccentric shaft type secondary transmission high-speed precision warm die forging machine. Background technique [0002] Die forging presses are mainly used for hot forging and isothermal superplastic forming of difficult-to-deform materials such as aluminum alloys, titanium alloys, superalloys, and powder alloys. Its forging feature is that it can improve the density of the deformed material through large pressure, long holding time and slow deformation speed, improve the comprehensive performance of the forging by refining the material grains, and improve the deformation uniformity of the entire forging, so that Difficult-to-deform materials and complex structural forgings meet the design requirements through isothermal forging and superplastic deformation, which can save 40% of materials and achieve the goal of less machining or near-net shape. ...
