Embodiment Construction

[0011] The following will be attached Figure 1 The present invention is described in further detail.

[0012] as attached figure 1 As shown: the whole electromagnet is supported by the armature jacket 1, and after a retaining ring is press-fitted at both ends of the coil sleeve 5, an electromagnetic coil is wound on the outer wall of the coil sleeve, and after winding, it is fixed together in the armature jacket, and impacts the base 3 and the lower end of the armature jacket 1 are screwed together, and the buffer spring 8 is first placed in the shaft hole of the impact base 3, and then the upper end of the armature 4 and the lower end of the impact pin 6 are screwed together so that the lower end of the armature 4 passes through The inner hole of the coil sleeve 5 is placed on the buffer spring 8 in the shaft hole of the impact base 5, so that the armature 4 moves axially relative to the coil sleeve 2 in the axial direction, and the impact cover 2 passes through the shaft h...

Abstract

The invention relates to an impact type electromagnet, belonging to the technical field of electromagnet. The impact type electromagnet is comprised of an armature coat, an impact lid, an impact base, an armature, a coil sleeve, an impact pin, an offsetting spring, a buffer spring, a retaining ring and a coil. The electromagnet is capable of instant impact. The electromagnetic device is provided with an impact pin which is connected to the moving armature by a whorl. The moving armature is direct pushing type. Acceleration force can be exerted upon the electromagnet by running the current through the winding coil. At the same time, the impact pin is kept in acceleration motion until the pin hits on an object at the maximum velocity when the impacted object receives the maximum force, thus ensuring a good impacting effect. The invention differs from other existing electromagnet in that the invention takes full advantage of the stability of the concerted force of magnetic leakage which enables a massive resultant force with slow reduction, so that the purpose of a long-term, high-velocity, and massive impact is realized. The mechanism of the invention is fast in response, simple and delicate in structure, and easy to use.

Description

technical field [0001] The invention belongs to the technical field of electromagnets, and in particular provides an impact electromagnet with instantaneous impact capability. Background technique [0002] At present, when the existing electromagnet is energized and closed, its armature has a short stroke, and the acceleration is small and the speed is slow. The existing electromagnet obviously cannot meet this requirement in the occasions where it is large and requires instant start and stop. Contents of the invention [0003] The object of the present invention is to provide an impact electromagnet. The principle of the electromagnet is to increase the acceleration force for the full movement of the armature by reasonably adjusting the main magnetic flux force and the leakage flux force, thereby generating a large impact force. [0004] The electromagnet is equipped with an impact pin, the impact pin is made of high hardness steel, and its length can be determined acco...
