Problems solved by technology
This traditional formwork has the following disadvantages: First, the mold clamping force is limited, which will affect the geometric accuracy of the formed part due to insufficient clamping force when the billet is extruded; second, the working stroke is limited, and a large stroke will reduce the elastic element.

The present invention relates to a closed die forging hydraulic die carrier equipment, and is characterized by that the upper female die and upper punching head of said die equipment is connected with upper die plate by means of apper female die seat, its lower punching head is rigid-supported on the lower die plate by means of lower punching head bearer, the hydraulic cylinder cover-mounted on the periphery of lower punching head bearer is fixedly connected on the lower die plate, and its lower female die is supported on the piston by means of lower fermale die seat. When it is used, the upper die plate is connected on the upper pressure plate of press machine, and when the upper female die and upper punching head are driven by upper pressure plate or press machine and moved downward, the upper and lower female dies are closed.
Description
technical field [0001] The invention belongs to a mold frame for precision forging. Background technique [0002] Closed die forging precision forming usually connects the mold with a special mold base to the press, and combines the action of the press with the action of the mold base to realize the tight closing of the upper and lower dies and the insertion of the upper and lower punches to complete the die. The process of forging and pressing the blank in the cavity, opening the mold and ejecting the workpiece. However, the traditional block die forging frame devices all adopt elastic element structures (such as metal springs or polyurethane springs) to realize the mold clamping function. This traditional formwork has the following disadvantages: First, the mold clamping force is limited, which will affect the geometric accuracy of the formed part due to insufficient clamping force when the billet is extruded; second, the working stroke is limited, and a large stroke will...
