Summary of information:We have more than ten years of experience in screw industry production. The main products are: slotted and elongated rou...

When using a rivet nut, drill a hole corresponding to the outer diameter of the rivet nut on the thin wall, then place the rivet nut on the bolt of the special rivet gun, push the handle to screw in the rivet nut, and put it into the drilled hole. In the workpiece, squeeze the handle, the rivet nut expands, and the deformed skirt bulges and deforms. At this time, the workpiece is tightened. After riveting, the handle is pulled out, the bolt is released from the rivet nut, and the corresponding screw is screwed into the rivet nut threaded hole. , forming a tight riveted body.

As the preferred embodiment of the above-mentioned embodiment, the motor 41 is provided with a thruster 46 that moves the cutting wheel 42 toward the conveying device 3. When the screw needs to be slotted, the thruster 46 generates a thrust toward the screw, and the motor 41 generates a thrust in the direction of the screw. Under the action, the groove is moved along the track 47 toward the screw. The other end of the motor 41 is provided with a bearing 45, and the output end of the motor is provided with a special-shaped wheel 44. The special-shaped wheel 44 is geared to the bearing 45. The wheel 42 is close to or away from the conveying device 3. When the grooving is completed, the special-shaped wheel 44 rotates and drives the bearing 45 to generate the opposite force from the above-mentioned thrust, so that the motor 41 moves back to the original position along the track 52.

In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. provides the following technical solutions: an anti-drop screw structure, including a connecting bolt and a fastening screw, the connecting bolt includes a connecting screw and a connecting nut, one end of the connecting screw It is integrally connected with the connecting nut, the surface of the connecting screw is provided with an external thread, the connecting bolt is movably mounted with a matching nut, the matching nut and the connecting bolt are connected by thread, and the interior of the connecting screw is provided There is a screw hole along the axis of the connecting screw. The connecting screw is provided with a number of slots along the axis. The slot extends into the screw hole. The screw hole is provided with an internal thread, and the screw hole is movable in the screw hole. A tightening screw is installed, the tightening screw includes a tightening screw and a tightening nut, one end of the tightening screw is integrally connected with the tightening nut, and the tightening screw is connected to the tightening nut through a screw hole Bolted thread connection.

Combination bolts refer to a bolt with a spring washer and a flat washer, which are combined by rubbing teeth. Before the combination bolt is used, the bolt, the spring washer and the flat washer are generally combined by a specific machine. The combined production line mainly includes the processes of feeding, discharging, feeding, charging, screwing and tightening. The existing combined bolt production equipment mainly transmits the bolts to each process through the conveyor belt, and finally completes the combined assembly. The machines in each process are scattered and the space is occupied. The vibrating plate feeding generally puts the bolt head up, and its bolts, spring washers, etc. After the flat pad is assembled, the fixation is poor, and it is easy to fall off during the assembly process.

According to the properties of nuts, there are mainly national standard (GB), German standard (DIN), international standard (ISO), Japanese standard (JIS), American standard (ASTM/ANSI) and other standards. Among them, the national standard, German standard, and Japanese standard are represented by M (such as M8, M16), and the American system and the British system are represented by fractions or # (such as 8#, 10#, 1/4, 3/8). Commonly used national standard GB41 Ⅰ type hexagonal nut - C grade GB6170 Ⅰ type hexagonal nut - A, B grade GB6171 I type hexagonal nut - fine thread - A, B grade GB6172 hexagonal thin nut - A, B grade - chamfering GB6173 Hexagonal Thin Nut - Fine Thread - A, B Grade GB6174 Hexagon Thin Nut - B Grade - No Chamfer GB6175 II Hexagonal Nut - A, B Grade GB6176 II Type Hexagonal Nut - Fine Thread - A, B Grade GB6177 Hexagon Method Blue face nut - grade A GB55 hexagonal thick nut GB56 hexagonal super thick nut GB1229 large hexagonal nut (high strength for steel structure)
