Riveting-free connecting tool with synchronous elastic adjusting device

Abstract

The invention provides a riveting-free connecting tool with a synchronous elastic adjusting device. The connecting tool comprises a first tool component with a punch and a second tool with a pressingdie, and an anvil is detachably connected to a die pressing body; the synchronous elastic adjusting device is arranged between movable pressing die elements and an elastic element; arc-shaped sectionsat the lower parts of the outer sides of the movable pressing die element are designed into cone parts, elastic arms abut against compensation arms of arc-shaped inclined wedge pieces in a lateral direction, the compensation arms of the arc-shaped wedge pieces abut against the cone parts of the movable pressing die elements in a side-to-side mode so as to transfer elastic force to the movable pressing die elements; and the synchronous elastic adjusting device further comprises a left worm gear and a right worm gear, the left worm gear and the right worm gear are fixedly connected to a left screw rod and a right screw rod, a synchronous worm is further arranged and drives the worm gears on the two sides, and the left worm gear and the right worm gear drive the left screw rod and the rightscrew rod to move up and down. According to the connecting tool, different anvils can be replaced according to different process requirements, and meanwhile, the movable pressing die elements do not need to be replaced; and the technical effects that the riveting-free connecting tool is low in cost, wide in application range and adjustable in elastic force are achieved.

Description

technical field [0001] The invention relates to the technical field of plate riveting, in particular to a rivetless connection tool with a synchronous elastic adjustment device. 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 compon...

Problems solved by technology

[0010] The invention provides a rivetless connection tool with a synchronous elastic adjustment device, which solves the technical problem that the anvil of the rivetless connection tool in the prior art is subjected to frequent impacts during the riveting process and is very easy to be damaged. Riveting of different materials and different thicknesses requires control of different riveting process parameters, different requirements for the model size of the anvil, and different requirements for the resilience of the elastic parts, which solves the problem of single function of the riveted connection tool in the prior art.
