Summary of information:We have more than ten years of production experience in the screw industry. The main products are: stainless steel adjus...

The embedded nut proposed by Guangdong Yueluo Hardware Industry Co., Ltd. is used to be embedded in an injection molded part. The embedded nut is arranged in a column shape and has a screw hole inside. The embedded nut includes an outer peripheral surface and is formed in the inner nut. The upper end surface and the lower end surface of the two ends of the embedded nut are provided with knurling on the outer peripheral surface, and a guide surface is formed at the connection between the outer peripheral surface and the lower end surface.

High-strength bolt connection has the advantages of simple construction, good mechanical performance, disassembly and replacement, fatigue resistance, and no loosening under dynamic load. It is a promising connection method. High-strength bolts use a special wrench to tighten the nut, so that the bolt generates a huge and controlled pre-tension. Under the action of pre-pressure, a large frictional force will be generated along the surface of the connected parts. Obviously, as long as the axial force is less than this frictional force, the components will not slip and the connection will not be damaged. This is the high-strength bolt connection. principle. High-strength bolted connections rely on the friction between the contact surfaces of the connectors to prevent them from sliding each other. In order to make the contact surfaces have sufficient friction, it is necessary to increase the clamping force of the components and increase the friction coefficient of the contact surfaces of the components. The clamping force between the components is achieved by applying pretension to the bolts, so the bolts must be made of high-strength steel, which is why it is called high-strength bolted connections. In high-strength bolted connections, the friction coefficient has a great influence on the bearing capacity. Tests show that the coefficient of friction is mainly affected by the form of the contact surface and the material of the components. In order to increase the friction coefficient of the contact surface, methods such as sandblasting and wire brush cleaning are often used to treat the contact surface of the components within the connection range during construction.

The t-bolt can be directly put into the groove of the aluminum profile. It can be automatically positioned and locked during the installation process. It is often used in conjunction with the flange nut. profiles to choose from. T-bolts are movable anchor bolts. Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread) that needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. There are hexagonal head, round head, square head, countersunk head and so on. Among them, the hexagonal head is commonly used. Generally, the countersunk head is used in places where the surface is required to be smooth without protrusions, because the countersunk head can be screwed into the part. Round heads can also be screwed into parts. The tightening force of the square head can be larger, but the size is large.

The development of a structure with simple production, reasonable structure and stable feeding is of great significance to the field of riveting automation. Technical realization elements: The purpose of this utility model is to overcome the deficiencies in the prior art, and to provide an automatic feeding device for pressure riveting nuts, which has a compact structure and a reasonable design, and can realize the automatic conveying of the pressure riveting nut on the pressure riveting die. Reduce the use of space, improve work efficiency and save labor costs. According to the technical scheme provided by the utility model: the automatic feeding device for riveting nuts, which is characterized in that: it includes an installation bracket, a connecting frame, a flap bracket, a material pushing cylinder, a material pushing block and a flap; the flap bracket is arranged on the installation Below the bracket and attached to the mounting bracket through the connecting bracket.

Gaskets are mechanical seals between two objects, usually used to prevent pressure, corrosion, and natural thermal expansion and contraction of pipes between two objects and leakage. Since machining the surface is not possible, irregularities can be filled with spacers. Gaskets are usually made from sheet materials such as pad paper, rubber, silicone rubber, metal, cork, felt, neoprene, rubber, fiberglass or plastic polymers such as Teflon. Gaskets for specific applications may contain asbestos. The existing gasket is easily deformed for a long time in use, and the gasket cannot play the role of making up the difference. In addition, during the use process of the gasket, the adhesion between the gasket and the nut or the mechanical surface becomes poor, resulting in a poor sealing effect.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: A-type flat key construction pins, countersunk head hexagon socket nuts, blind hole pressure riveting studs, aluminum pull rivets and other products, we We can provide you with the right fastener solution for you.
