Pressing rivet die for hoist nameplate

Abstract

The invention discloses a pressing rivet die for a hoist nameplate and belongs to the technical field of hoist nameplate pressing rivet dies. The pressing rivet die comprises a bottom plate, a positioning plate fixed to the bottom plate, an upper die body arranged on the upper portion of the positioning plate, and a die shank fixedly connected with the upper die body. A hoist casing is provided with a casing end face and a casing brim provided with a pin hole. The casing end face is provided with a nameplate groove for accommodating the hoist nameplate. A positioning pin for positioning of thepin hole is arranged on the bottom plate. Two elastic ejection rods are symmetrically arranged on the positioning plate. At least two riveting rods are symmetrically arranged on the positioning plate. The riveting rods are lower than the two elastic ejection rods. The top end face of each riveting rod extends axially to form a small conical riveting head and a shallow groove surrounding the rootof the small conical riveting head. The small conical riveting heads are used for stretching a semi-hollow riveting body part. A complete and consistent riveting flange is formed at the end port of the semi-hollow riveting body part through the shallow grooves. Multiple positions of the nameplate can be simultaneously pressed and riveted by the die, the hoist nameplate and the hoist casing are riveted firmly, and the riveting quality coherence is high.

Description

【Technical field】 [0001] The invention relates to a mold for riveting a nameplate of a gourd, which is used for riveting and installing the nameplate of a gourd on a gourd casing, and belongs to the technical field of riveting molds for a nameplate of a gourd. 【Background technique】 [0002] The hoist nameplate is used by the hoist manufacturer to name and mark some main technical indicators required by the rated operating conditions of the hoist, in order to remind users in good faith that normal use will not damage the hoist due to operations such as overloading. The hoist nameplate is usually in the shape of a metal sheet. It is An indispensable accessory for lifting machinery. The gourd nameplate is placed on the surface of the gourd cover, and there are multiple through holes on the gourd nameplate, and the corresponding riveting holes are set on the gourd cover. After the hole and the riveting hole are connected by riveting, the knurled part of the flower rivet is tig...

AI Technical Summary

Problems solved by technology

[0003] Generally, only one flower rivet can be riveted at a time, that is, the flower rivets are riveted one by one. When riveting the second flower rivet, the gourd cover and the nameplate of the gourd need to be repositioned, which not only reduces the work efficiency, but also has different riveting quality;

[0004] Due to the different tightness between the knurled part and the riveting hole, when the hoist is used and placed, the hoist shakes and the cover bumps, etc., the nameplate of the hoist sometimes falls off, and the nameplate of the hoist also falls off due to vibration and bumps during transportation. , so that the hoist loses its indicating function, in view of this, it is necessary to improve the riveting quality of the existing hoist nameplate
