Design of swing riveting machine

The wax thermostat for automobile produced by our factory has a process of riveting the bracket (H62) to the housing (Fig. 1). Technical requirements for riveting: not only must be solid, firm, but also beautiful and clean. For many years, the riveting method has been unidirectionally rotated and riveted. This riveting method is not only very noisy (nearly 70dB) due to the slamming impact of the boring wheel and the rivet point, but also the riveted pattern is smashed. Seriously affected the appearance quality of the product. In response to the above situation, we made a swing riveting machine (Fig. 2).

UCF Pillow Bearing

The UCF pillow block mounted bearing series has four bolt holes, and a set screw lock is designed for mounting onto bearing surfaces parallel to the shaft axis, such as conveyor belts. This ready-to-mount unit has solid base cast iron housing, chrome steel bearings, and is designed for efficient operation at a wide range of speeds. This one-piece pillow block housing allows for a stationary outer ring and rotating inner ring. Insert bearing maintains the separation between moving parts to reduce rotational friction, and to support radial and axial loads. The bearing is secured to the shaft with set screws to prevent slippage. This mounted bearing is used in food and beverage manufacturing, textile industry and many other industrial manufacturing.

Pillow blocks are usually referred to the housings which have a bearing fitted into them & thus the user need not purchase the bearings separately. Pillow blocks are usually mounted in cleaner environments & generally are meant for lesser loads of general industry. These differ from "plummer blocks" which are bearing housings supplied without any bearings & are usually meant for higher load ratings & corrosive industrial environments. However the terms pillow-block & plummer-block are used interchangeably in certain parts of the world.

However fundamental application of both types is the same which is to primarily mount bearings safely enabling their outer ring to be stationary while allowing rotation of the inner ring. The housing is bolted to a foundation through the holes in the base. Bearing housings are either split type or unsplit type. Split type housings are usually two piece housings where the cap and base can be detached. While certain series are one single piece housings. Various seals are provided to prevent dust and other contaminants from entering the housing. Thus the housing provides a clean environment for the expensive bearings to freely rotate hence increasing their performance and duty cycle.

Bearing housings are usually made of grey cast iron. However various different grades of metals can be used to manufacture the same.
