Rivets are mostly used for fixed riveting and movable riveting between parts. The rivets used for movable riveting are mostly cylindrical, and there is no size limit for riveted parts, which is easy to cause parts to be squeezed and deformed during riveting. For example, The parts are inserted into the parts for active riveting. When riveting, the riveting force can easily cause the parts to clamp the parts, which in turn causes difficulty in the movement of the parts and the parts, high operating force and noise problems, and the parts are easily damaged.

The common riveting techniques of non-blind rivets are divided into cold riveting and hot riveting. Cold riveting is a riveting method that uses a rivet rod to partially pressurize the rivet, and continuously swings around the center or the rivet is forced to expand until the rivet is formed. The common cold riveting methods are the pendulum riveting method and the radial riveting method. The pendulum rolling riveting method is easy to understand, and the rivet head only swings and rolls in the circumferential direction.

With the rapid development of China's machinery industry, especially the development of heavy industry, the demand for large-scale metal processing equipment is increasing; at the same time, higher requirements are also placed on the technical parameters of the equipment. For some large-scale CNC equipment, to ensure the machining accuracy of the whole product, it is not only necessary to rely on high-performance components such as full closed-loop control and precision transmission components, but also requires the positioning and stability of the joint surfaces between the large and medium-sized components of the equipment. The common positioning of the joint surface between large components adopts flat key positioning, and this method requires processing the keyway at the joint surface of the large components. Since the joint surface of large parts is affected by factors such as processing and splicing, it cannot guarantee that the keyways on the large parts combined can be matched according to the theoretical requirements. Therefore, the positioning flat key needs to press the flat key in the two parts of large parts. Different repair allowances Trim into a stepped shape. The height difference of this keyway in different large components makes a single flat key need to be repaired on four sides, which increases the difficulty of the key repair process and makes it difficult to improve work efficiency. Not only that, when the flat key is repaired and assembled, it must be in an interference fit with the keyway, which makes the disassembly and assembly of the flat key more laborious.

screw is a tool that uses the physical and mathematical principles of the circular rotation and rotation of the oblique surface of an object to gradually fasten the mechanism of the utensil. A screw is a common term for fasteners, an everyday colloquial language. Screws are indispensable industrial necessities in daily life: tiny screws used in cameras, glasses, clocks, electronics, etc.; general screws in televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large screws are used. Screws and nuts; transportation equipment, airplanes, trams, automobiles, etc. are used together with large and small screws. Screws have important tasks in industry. As long as there is industry on earth, the function of screws will always be important. The screw is a common invention in people's production and life for thousands of years. According to the application field, it is a great invention of human beings. At present, the head of the screw on the market is generally punched with a cross groove or a word groove, which is used for tightening or Remove the screw, but the cross slot or the slot is easy to deform after a long time, it is difficult to disassemble it with tools, and sometimes the tool of the corresponding size cannot be found and the disassembly cannot be carried out, and the disassembly is relatively inconvenient.

A screw suitable for a variety of tools is a single-structure threaded part, including a screw body and a screw head. The outer surface of the screw body is processed with an external thread 1, and the outer side of the screw head is formed by six screw heads. Prismatic, the top surface of each edge of the outer hexagonal prism is a boss, between each boss is an end face groove 4, and the middle of each boss is provided with an end face hole 3; the inner side of the screw head is formed by six screw heads. The side surface 5 forms an inner hexagonal prism hole, and the bottom of the inner hexagonal prism hole is processed with a cross groove 16 .

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: embossed nuts and nuts, extended full-tooth hexagon screws, large ear wing nuts, gasket box sets and other products, we can provide you with suitable products Your fastener solution.
