Heavy electromagnetic riveter

Abstract

The invention discloses a heavy electromagnetic riveter, and relates to the field of electromagnetic riveters. The heavy electromagnetic riveter comprises a riveter main body part, a driving part and a handle part, the riveter main body part comprises a shell, the driving part is arranged in the shell, the driving part comprises a first buffer mechanism, the handle part comprises an operation handle, the operation handle and the shell are of a split structure, and a second buffer mechanism is arranged between the operation handle and the shell. The heavy electromagnetic riveter is heavy in overall structure, a large primary coil can be installed, large electromagnetic force can be generated in the actual use process, the generated recoil force is small due to the large mass ratio, the operation handle and the shell are connected in a separated mode, the recoil force is prevented from directly acting on an operator in the operation process, meanwhile, a double-buffering structure is designed, 70%-90% of riveting recoil force can be consumed, and the operation safety is improved.

Description

technical field [0001] The invention relates to the field of electromagnetic riveting guns, in particular to a heavy-duty electromagnetic riveting gun. Background technique [0002] Electromagnetic riveting is a new type of riveting process. It uses pulsed magnetic field force to deform metal blanks with high-speed loading forming method. As a key technology to solve difficult-to-form material rivets, large-diameter rivets and composite material structure riveting problems, it has been applied in aviation. In the field of aerospace, it also has broad application prospects in automobiles, ships, and bridge engineering. [0003] At present, electromagnetic riveting equipment is generally a general-purpose structure, and there are many problems in practical applications. For example, the riveting ability cannot complete the forming of large-diameter rivets or the installation of large-diameter, thick interlayer and high-interference interference fit fasteners, and cannot solve ...

AI Technical Summary

Problems solved by technology

[0003] At present, electromagnetic riveting equipment is generally a general-purpose structure, and there are many problems in practical applications. For example, the riveting ability cannot complete the forming of large-diameter rivets or the installation of large-diameter, thick interlayer and high-interference interference fit fasteners, and cannot solve the problem of riveting gun level. The problem of overturning moment is easy to occur in the centering process. At the same time, when the recoil force is large during the riveting process, the riveting gun cannot provide a good damping and buffering function, resulting in unfriendly operation of the riveting operation and low riveting efficiency.
