Description

Technical Field

[0001] The utility model relates to the technical field of rivet stud assembly equipment, in particular to an online punching automatic rivet stud assembly equipment. Background Art

[0002] The punching process of hardware materials is widely used in the manufacturing industry. It is not limited to simple punching operations, but can also be used for multifunctional applications through specific punching designs, such as assembling rivet studs. As a connector, the rivet stud plays a vital role in the assembly of metal structural parts. It connects two or more workpieces tightly together through mechanical deformation, providing a strong and durable connection method.

[0003] In the traditional hardware manufacturing process, punching and rivet stud pressing are usually two separate steps. First, the hardware is punched on a punch press; then, the punched hardware is transferred to another workstation, where workers manually place the rivet studs and use a special riveting machine to press them. This secondary processing method is not only inefficient, but also requires more manpower, increasing production costs and the possibility of human error.

[0004] In order to overcome these problems, we propose an online punching automatic riveting column equipment. Utility Model Content

[0013] Furthermore, the upper die assembly includes an upper die plate, at the bottom of which a punch is fixed, and the punch is used to push the rivet column entering the perforation into the hole of the product.

[0014] Furthermore, limiting blocks are provided on the opposite surfaces of the lower template and the upper template, and the product is clamped between the two limiting blocks.

[0015] The utility model proposes an online stamping automatic rivet stud installation device, which has the beneficial effect that: in the utility model, a vibration plate is used to send the rivet stud to the upper part of the product rivet stud installation position of the lower die assembly through a track, and the punch is fixed below the upper die plate.
