Metal sheet no-rivet connecting tool

Abstract

The invention provides a metal sheet no-rivet connecting tool. The metal sheet no-rivet connecting tool comprises a first tool assembly provided with a punch and a second tool assembly provided with apressing die, and an anvil and a pressing die body are detachably connected. An elastic regulating device is arrange between a movable pressing die element and an elastic element, an arc section of the lower portion of the outer side of the movable pressing die element is designed to be a cone portion, an elastic abuts against a compensation arm of an arc inclined wedge piece laterally, and the compensation arm of the arc inclined wedge piece abuts against the cone portion of the movable pressing die element to transmit elastic force to the movable pressing die element. The elastic regulatingdevice further comprises a worm wheel and a worm, the worm wheel is fixedly connected with a screw, the worm wheel is driven by the worm, and the screw is driven by the worm to move up and down. Diffident anvils can be replaced according to different process requirements, and the movable pressing die element is not required to be placed. The metal sheet no-rivet connecting tool realizes the technical effects of low cost, wide range of application and adjustable elastic force.

Description

technical field [0001] The invention relates to the technical field of riveting of plates, in particular to a rivetless connection tool for metal plates. Background technique [0002] A rivetless connection tool includes two separate tool parts that cooperate for creating a joint. The first tool part has the form of a punch, which is driven for linear movement in the direction of the coaxial second tool part, which is in the form of a die, with a die cavity at the top, arranged at the top There is an anvil. [0003] For the manufacture of the joint, the sheet metal member is positioned against a second tool part provided with a movable die element arranged slidingly laterally on the support surface, the force from the elastic element against the support surface. The elastic element may be an elastomeric ring or a helical tube formed metal spring around the movable die element. [0004] The approaching punch strikes the surface of one of the components to be joined. The ...

AI Technical Summary

Problems solved by technology

[0011] The invention provides a rivetless connection tool for metal plates, which solves the technical problem that the anvil of the rivetless connection tool for metal plates in the prior art is subjected to frequent impacts during the riveting process and is very easy to be damaged. The riveting of the thickness needs to control different riveting process parameters, and has different requirements for the model size of the anvil, as well as different requirements for the resilience of the elastic parts, which solves the defects of the single function of the metal plate riveless connection tool in the prior art and The defect of non-adjustable elastic force
