Service Hotlinerivet dismantling method and a dismantling device thereof. The dismantling method firstly places a riveting piece with a failed rivet installed on a die having a blanking hole, and then uses a punch that coincides with the center line of the rivet on the riveting piece to impact the rivet. , the rivet falls into the blanking hole under the impact of the punch to complete the disassembly; the dismantling device includes a concave die for positioning and supporting the riveting piece installed with the failed rivet, and the concave die is provided with a blanking hole; The upper part of the die is provided with a punch for punching the rivet into the blanking hole, and the punch and the center line of the rivet are coincident; Yueluo adopts the punch to dismantle the failed rivet, which not only has high work efficiency, but also has high work strength. It is small, and does not damage the riveting parts on which the rivets are installed; the impact process will not cause the rivets to splash, and the safety is high; and the cost of dismantling equipment is low.
Use performance self-tapping screws for self-tapping screws with a diameter of 0.8mm to 12mm. For this type of screw, it generally has a high hardness. Self-tapping screws must be screwed into the test, that is, screw the screw into a test plate to check whether the hardness of the screw meets the standard. The shape of the drill tail, the hardness of this kind of screw is very strong. Compared with ordinary screws, it not only has better maintenance ability, but also has a very strong effect in connecting objects. For screws with this performance, it is generally not necessary. Auxiliary processing can directly drill a hole on the object and lock it into the object, which is not only very convenient to use, but also greatly improves work efficiency. This kind of drill screw can be said to be the first choice of the staff in various fields.
In order to prevent the waste of materials, those skilled in the art select steel wire as the processing material, and form an annular ring body by drawing the steel wire. Such as the announcement: CN103522009's invention name is a method of processing a retaining ring. The steel wire is used as the processing material, and the processing is carried out by drawing. After the steel wire is drawn and formed, annealing is performed. After the annealing is completed, the forming needs to bundle the steel wire. Since the cross section of the steel wire is rectangular, when it is drawn into the retaining ring base, the cross section changes due to the extrusion of the material, and the inner ring of the retaining ring base will be higher than the outer ring (forming a slope). The deformation is large. At this time, the punching of the opening of the retaining ring base body will produce a slump or cause greater material deformation; therefore, the retaining ring base body needs to be bundled. The bundling process is to prevent the material from being heated more during the quenching process. At the same time, it also has a certain adjustment effect during the quenching process, which makes the inclined surface smaller; but after the quenching is completed, the hardness of the retaining ring base increases, and the punching process for the upper opening will become more complicated.
The circlip is a common limiting element in the mechanical field, which is mainly used to limit the axial limit of mechanical parts. At present, the common circlips on the market are all circular rings with an opening. The circular ring has a certain elastic deformation capacity. When in use, the circlip can be detachably assembled to the mechanical on the part. However, the defect of the circlip adopting the one-piece ring is that the circlip is easily broken when frequently disassembled and used, and the service life is short.
