Abstract

The invention discloses a continuous punching and nut riveting device for an automobile door lock catch, which is used for continuously punching and riveting nuts on a material tape in the process of manufacturing the door lock catch. A die body consists of upper and lower die assemblies; an automatic nut conveyor connected with an automatic nut conveying electric control cabinet is arranged on front and rear sides of a lower die holder; when the material tape is subjected to early-phase blanking, chamfering and molding for riveting, the die is opened, the material tape is floated, the nut conveyor automatically feeds nuts of which the riveting surfaces face upwards, and puts the nuts into a riveting female die positioning groove below the material tape; an upper slide block descends, a riveting male die extrudes the material tape, and a lock catch plate material flows to a nut riveting taper available part so as to realize riveting. By adopting a mode of combining the automatic nut conveyor with a continuous nut riveting die, the production efficiency is greatly improved; the actions of automatically feeding and automatically conveying nuts are accurate; the material tape is accurately guided and positioned; and the produced workpieces are attractive in appearance, high in accuracy, high in riveting strength without disordered wires, stable in quality and environmentally-friendly; the labor intensity of a worker is greatly reduced; and the device can be used for riveting other products in different specifications and types.

Description

technical field

[0001] The invention relates to the technical field of automobile manufacturing, and is a device for continuously punching riveting nuts on a material belt when making door lock buckles. Background technique

[0002] Image 6 Shown is a three-dimensional schematic diagram of the universal door lock catch of an automobile. The door lock catch is an assembly of a strike plate with a serial number of 34 and a nut shown in a serial number of 35, and is installed in the inner frame of the automobile door to fix the door lock. Automobile door locks are supplied to many models, with the same or similar structure and four pieces for one car with four doors. The market demand is huge. At present, the production of locks usually adopts the process scheme of stamping (blanking punching, forming, punching chamfering) + welding, which has the following shortcomings:

[0003] 1. The structure of the stamping die is simple, but three sets of dies are required for blanking ...
