Service Hotlinescrew is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the parts of the object step by step. Since the parts to be fixed are different, different types of screws are required for different applications. Press screw is a new type of fastener applied to thin plate or sheet metal. The principle is to press the embossed teeth into the preset holes of the sheet metal. The diameter of the general preset holes is slightly smaller than the outer diameter of the pressure riveting screw. The periphery of the hole is plastically deformed, and the deformed object is squeezed into the guide groove, thereby producing a locking effect. However, the existing pressing screws are easy to loosen due to long use time or frequent vibrations, which is prone to certain hidden dangers.
In response to the above situation, Yueluo uses various methods to fasten the locked nuts and bolts in actual operation, such as super glue, electric welding, secondary reinforcement by perforation, etc., but there is still no way to get it right Solve the phenomenon that the nut is loose and displaced.
Rivets for blind holes, including a cap head and a hole post, the cap head is fixed on one end face of the hole post, a tip is formed on the other end face of the hole post, and the end of the hole post close to the cap head is along its side circumference An annular groove is formed concave inward. After the hole column of the blind hole is placed in the blind hole position of the metal piece, the tip of the end face of the hole column is squeezed into the metal material under the end face of the hole column under the action of external force, and the metal material on the side of the hole column is also affected by the hole. The extrusion of the side of the column makes part of the metal material completely squeezed into the annular groove, so that the annular groove is filled more firmly, and at the same time, the tip is squeezed into the metal material, which can double-position the rivet. Therefore, the self-riveting of the rivet is realized. The rivet also has the advantages of simple structure, simple and fast installation, and no cracking caused by impact and other undesirable phenomena.
In the prior art, the hardware and the handle are generally assembled and connected by means of rivet riveting; in the process of assembling the hardware and the handle, the prior art adopts manual operation to realize the riveting and assembling process, which is time-consuming and labor-intensive. and low productivity.
rivet automatic feeding device comprises a feeding installation frame, the upper end of the feeding installation frame is provided with a horizontally arranged receiving block mounting plate, the upper surface of the receiving block installation plate is provided with a rivet receiving block, a rivet The upper surface of the receiving block is provided with a receiving block movable groove that opens upward and completely penetrates left and right. The left movable receiving rod can be embedded in the receiving block movable groove relatively movably, and the right movable receiving rod is located on the right end side of the left movable receiving rod. The receiving rod, the right end of the left movable receiving rod is provided with a left receiving groove that opens upward, and the left end of the right movable receiving block is provided with a right receiving groove that opens upward;
