Lower die holder structure with self-adaptive bearing capacity

Abstract

The invention discloses a lower die holder structure with the self-adaptive bearing capacity. The lower die holder structure comprises a lower die holder main body; an adjusting assembly is arranged at the bottom of the inner end of the lower die holder main body; a female die assembly is connected to the upper end of the adjusting assembly in a telescopic mode; the female die assembly comprises afirst die set and a second die set; a first die set is arranged on one side of the inner end of the female die assembly; the side end of the first die set is rotationally connected with the second die set; the first die set comprises a first bearing frame, a first spring frame rod, a rotating shaft frame and a lantern ring; the first bearing frame is arranged in the center of the inner end of thefirst die set; the center of the first bearing frame is elastically connected with the first spring frame rod; the side end of the first bearing frame is rotationally connected with the rotating shaft frame; and the lantern ring is fixedly connected to the top of the rotating shaft frame in a sleeving mode. According to the lower die holder structure with the self-adaptive bearing capacity, through arrangement of the adjusting assembly, the purpose of inner end self-adaption is achieved.

Description

technical field [0001] The invention relates to the technical field of mold equipment, in particular to a lower mold base structure with self-adaptive bearing capacity. Background technique [0002] The lower die is the lower half of the entire punching die, that is, the die part installed on the working table of the press. The lower die seat is the part of the lower die that is in contact with the working table of the press. It is generally a plate, which is directly fixed on the press. The table top or backing plate plays the role of support and subsequent bearing. Through the deformation of the inner end mold, the implementation of stamping and other processes is realized, which is helpful for the overall processing and production, and through the design of the lower mold base structure, it can meet different The needs of component production provide guarantee for mechanized processing and production, but the current structure of the lower die base has the following probl...
