Abstract

A balance apparatus for lifting the large die from machine-tool in order to exchange die is composed of two lifting arms pivoted with each other to form a manipulator, and a cylinder whose telescopic rod has the nut for connecting the die. The weight of die can be balanced by said cylinder.

Description

technical field [0001] The invention relates to machine tool technology, especially the die changing and lifting technology of its large mold. Background technique [0002] In order to meet the needs of production and processing, the mold must be replaced, especially when replacing the large-caliber mold. In order to reduce the labor intensity, two reversing rollers are fixed on the existing machine tool, and the mold is lifted by the sling to leave the working position, and then Push it away manually to make it leave the mold positioning hole. This hoisting device still cannot break away from the operator from the strong labor intensity, and because the lifting stability of the sling is extremely poor, it also brings potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to design a stable and labor-saving machine tool mold lifting balance device for machine tools such as forming machines and presses. [0004] The present in...
