Service HotlineGuangdong Yueluo Hardware Industry Co., Ltd. discloses a low-carbon steel rivet nut fastened to a thin-walled and thin-plate fastener. The rivet nut fastener is composed of a brim, a deformed skirt, and a threaded hole. Using low carbon steel cold extrusion, the brim is formed by cold heading, the deformed skirt is extruded in the concave die, and the thread hole of the nut tapping skirt is extruded at the lower end of the deformed skirt. It is characterized in that there are fish teeth under the brim; the outer side of the lower end of the threaded hole has a lead angle; the cross-section of the thread of the inner wall of the threaded hole is an isosceles trapezoid, and the upper bottom of the trapezoid is a concave solitary shape, and the fastener does not need to be welded. , Single-sided riveting, easy operation and firm connection.
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.
The hinge is a hinge, which is often composed of two folds. It is a part that connects the two parts of the object and can make it move. The hinge supporting screws are installed on the corresponding objects. For different use environments, the requirements for the supporting screws are also different. different. Most of the existing screws are set to a single-threaded structure. When used to cut into a wooden door, the cutting speed is slow, and the cutting effect is not ideal, which is not conducive to cutting into a hard wooden door, etc., and the commonly used screws are often made of iron materials. It is easy to rust after contact with water vapor, reducing the service life; in addition, when the screw is driven into the wooden door, the chips generated cannot be discharged in time, and stay inside the wooden door and surround the screw, forming expansion stress, thereby squeezing the wooden substrate, which is not conducive to the screw. The connection with the wooden door is stable, which easily affects the normal installation of the hinge, and the use effect is poor. To sum up, in order to solve the shortcomings of the existing screw structure for hinges, Guangdong Yueluo Hardware Industry Co., Ltd. designed a hinge screw with simple structure, convenient use, fast construction and good effect.
In the mechanical structure, the existing seals are used on the end face of the bolt or the end face of the oil joint. The copper washer is often used as the seal, and the copper washer can only be used once, and it will become hard after the second use, reducing its sealing performance. Especially when it is used on the oil drain bolt (also known as the oil drain plug) of the oil pan of the automobile engine, it is necessary to do a maintenance and replace a copper washer, otherwise it is easy to cause oil leakage. Even so, the wear of the screw hole of the engine oil pan is also very big. It is also difficult for ordinary auto repair shops to replace one copper washer at a time.
Generally, the most commonly used material on the market is iron. The iron one is known as carbon steel. It is punched out or turned. After being manufactured, it is in its natural color. In order to prevent rusting, it is necessary to Electroplated. The stainless steel rivet nuts do not need electroplating. In the case of iron, the color of electroplating is generally determined by the customer, and the color of the electroplating depends on what color the customer needs. There are also some requirements for salt spray time. Some electroplating colors have a higher salt spray time, and some electroplating, less rust in a few hours. Another point is to see whether the customer needs to export the product. Generally, the export needs to be environmentally friendly, and some domestic ones also need it, but most of them are not needed.
