Electromagnetic rivetter

Abstract

An electromagnetic rivetter features that several 3-5 KV pulse capacitors are parallelly connected in its power supply system, the programmable controller and real-time digital display of voltage are used in its operating circuit, the overcurrent, overvoltage, overcharge and leakage monitor and protection are added to its control system and Its riveting hitter has dual damping layers. Its advantages are high capacitor capacity, low riveting voltage and loading rate, low recoil and noise, low cost and high riveting quality.

Description

(1) Technical field: [0001] The electromagnetic riveting equipment involved in the present invention is mainly used for riveting rivets of various materials in aviation, aerospace, automobile and bridge engineering, and is suitable for riveting rivets of difficult-to-form materials and large-diameter rivets. (two) background technology: [0002] In the manufacture of aviation and aerospace engineering products, a large number of rivets of various materials need to be riveted. Traditional riveting methods are: [0003] The hammer riveting method using compressed air as the power source is more commonly used. However, this riveting method produces large recoil and noise, poor working conditions, and workers are prone to fatigue. The quality of riveting is affected by human factors, and the recoil generated when riveting large-diameter rivets is difficult for workers to bear. [0004] The pressure riveting method with hydraulic pressure as the power source. The static pressu...

Problems solved by technology

This riveting method is inefficient and expensive

In order to avoid the difficulties encountered when riveting large-diameter rivets, sometimes screw connections have to be used instead of riveting in the design, which increases the structural weight and reduces the connection efficiency.
