The riveting process performed by press riveting machines offers several distinct advantages, notably in terms of consistent quality, superior surface finish, enhanced production efficiency, and the ability to prevent deformation. Thanks to these outstanding benefits, there are various types of press riveting machines designed using this method. The two most common types are portable and stationary models. Riveting is typically categorized into two methods: impact riveting and static-pressure riveting. However, static pressure is the preferred approach for most applications, and within this method, there are two primary techniques: riveting with a pin and riveting without a pin.
Riveting Press Riveting offers several distinct advantages, particularly in terms of consistent quality, superior surface finish, enhanced production efficiency, and effective prevention of deformation. Thanks to these outstanding benefits, there are many types of press riveting machines designed using this method. The two most common varieties are portable and stationary models. Riveting is typically categorized into two methods: impact riveting and static-pressure riveting. However, static pressure is the preferred approach in most applications, and it can be carried out in two primary ways—either with or without rivets.
Riveting with rivets on a press-riveting machine places high demands on both the quality of the rivet joint and the precision of the rivet holes. The primary manufacturing methods involve drilling, with punching and reaming being two commonly used drilling techniques.
1. The hole is roughly cross-shaped.
2. The quality of holes, such as broken edges, cracks, and other defects.
3. Issues such as aperture deviation, roundness, and internal burrs
Understanding riveting machines can be approached from multiple angles, as there are various methods for joining materials—such as screw fastening, adhesive bonding, and welding. Therefore, in many situations, a riveting machine isn’t the only viable option. This is not only due to the inherent advantages of different joining techniques but also because of the limitations and drawbacks associated with the riveting process itself.
Its major drawback is that it’s easily constrained by structural limitations, and riveting equipment comes with a relatively high price tag. That’s from the equipment perspective. As for the riveting process itself, riveting can reduce fatigue strength and also fails to provide adequate air tightness.
As it evolves, most press riveting machines now feature practical automatic control systems, with PLC-based control being particularly common.
At Riveting Press PLC control is used to generate instantaneous high-pressure riveting in the rivet head, enabling the entire riveting process to be completed. During operation, the upper and lower dies are controlled by the PLC, serving as the core component of the riveting mechanism.
Generally, two types of riveting control are common: manual control and PLC-based automatic control. Each has its own advantages and disadvantages. However, their functionality is essentially the same as that of up-and-down movement. Typically, the control method involves several dynamic riveting steps.
1. The rivet head rapidly moves downward within its stroke range to the selected position.
2. Lower the mold to the predetermined position.
3. Pressure Testing and Riveting
4. Relocate the rivet head and proceed with the next riveting operation.
5. After the riveting stroke is completed, return to the original position.
Typically, the process involves approaching quickly, slow riveting, gripping, and then returning.
PLC-controlled Riveting Press This method is generally suitable for riveting larger joints. Its advantages include consistent, reliable quality, high efficiency, and even load distribution. However, manually operating smaller machines lacks flexibility, so manual riveting still remains necessary in certain applications.
Like any ordinary machine, it requires attention to both operation and maintenance. Keeping it in proper working condition during use is the best way to maintain it effectively.
1. The riveting range is fixed: The parameters of the press-riveting machine are limited, and riveting any product outside this range will reduce its service life.
2. Rust prevention for riveting machines: Most riveting equipment is made primarily of steel, and rust can compromise the precision of the riveting process. Therefore, it’s important to clean them thoroughly as soon as possible.
3. Joint: The joint is a critical component that experiences frequent movement. It should be cleaned regularly. If effective cleaning isn’t possible during operation, you can clean it after disassembling the part. Be careful not to apply excessive force during disassembly, as this could lead to misalignment.
4. Lubricants: To understand the role of lubricants, a sufficient amount is needed here.
5. Try to avoid fatigue as much as possible, since under high pressure, fatigue can cause gaps between internal components.

Riveting Press: An Introduction to the Riveting Press
Rivets may seem unassuming in everyday life, yet they are widely used across society. From aerospace and aviation to office equipment, electronics, and even playground facilities—and even extending to items like leather bags and fashion accessories—rivets play a crucial role in countless applications. As society continues to evolve, press riveting machines have become increasingly diverse in design and functionality. Press riveting machines are primarily used for joining solid rivets, hollow rivets, and other types of fasteners. The solid end of a rivet can be shaped into either a flat head or a mushroom head, while hollow rivets can be crimped to create a flared effect.
