Space-saving elastic combined device

Abstract

The invention provides a space-saving elastic combined device. A bearing plate is mounted at the upper ends of tertiary elastic members and connected with the bottom of a draw piece; the tertiary elastic members are mounted on the support frame lower plate of a tertiary elastic member support frame; primary elastic member positioning posts are mounted on a support base; secondary elastic members are mounted on the support frame lower plate of a secondary elastic member support frame; the tertiary elastic member support frame is mounted between the tertiary elastic elements and the secondary elastic elements; the support frame upper plate of the tertiary elastic member support frame is pressed at the upper ends of the secondary elastic members; the secondary elastic member support frame is mounted between the secondary elastic members and the primary elastic members; the support frame upper plate of the secondary elastic member support frame is pressed at the upper ends of the primary elastic members; and the primary elastic members are mounted on the support base. According to the space-saving elastic combined device, process requirements of small continuous stress variation range and relatively large continuous stress stroke can be met better.

Description

technical field [0001] The invention belongs to an elastic device, in particular to a space-saving elastic combination device. Background technique [0002] In a mechanical device with a small range of continuous force changes and a large continuous force stroke, such as the elastic part that applies force to the blank holder in the large-depth calendering die, and the part that applies force to the bottom of the large-depth calender during the forming process Elastic parts are required to have a continuous elastic force with a small range of variation during the entire forming stroke. For the blank holder ring, at the beginning of forming, it is necessary to have a large blank holder force to press the deformation area of ​​the rolled part to prevent wrinkling in the deformation area. The edge force does not change much, which can meet the demand of blank holder. Currently used spring, rubber and other elastic member structures, at the beginning of forming, in order to me...
