The specifications of copper inserts are: internal thread specification 1/4-20, outer diameter 10mm, length 15mm mesh pattern copper nut, drawn from flower pull raw materials. The automatic lathe completes at one time: stocking → chamfering → drilling → hooking chamfering → tapping. Stable size, no eccentric internal thread. Material selection: copper C3604, Rohs PASS. The copper nut is used in injection molded parts.
At present, injection molding screws are widely used in various electronic and automotive components, including a body, the middle of which is provided with a through hole 3, the body head 1 has a hexagonal cross-section, and the tail 2 is provided with screw teeth. When in use, the middle through hole 3 of the main body will first put the wire harness, and then fix it by injection molding from the head I, and the threads of the tail 13 should be connected and installed with other components. Because the head I of the main body is hexagonal, the torque provided after injection molding is insufficient. Therefore, after the external thread is installed and connected with other components, the head is prone to slip, the installation is not reliable, and there is no push-pull force, resulting in product failure and increased safety hazards.
With the development of science and technology, human construction technology has also continued to improve. In terms of tools used in construction, it is constantly innovating and bringing forth new ideas, in order to enable personnel operating on construction sites to work more safely and efficiently; among them, screws The belt has become an indispensable auxiliary tool in the construction industry, especially for those who need to operate in a more dangerous high position. With the assistance of a nailing machine and a screw belt, it is quite convenient to screw together. Locked work to improve work safety and efficiency.
Riveting is the most traditional way of connecting metal parts. It has the advantages of easy operation, high reliability and not easy to deform. It is widely used in the skeleton of outdoor products such as tents and camp beds. Commonly used aluminum alloy rivets use their own deformation or interference to connect the parts of the riveted parts in the riveting process. Due to cost and functional considerations, the rivet and the riveted material are often different, which is easy to occur in outdoor high humidity. Electrochemical corrosion, and the commonly used high-strength thin-walled pipes have a large shear stress on the aluminum alloy rivets at the riveting point. Under the combined action of the above two factors, it is easy to cause deformation or even breakage at the riveting point, which affects the life of outdoor products. A kind of Corrosion and shear resistant aluminium alloy rivets.
In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. provides the following technical solution: a square nut, including a nut body, the nut body is in the shape of a cube, the side length is 7.6mm, the height is 2.4mm, and the nut body is up and down. Both ends are respectively provided with a circular protrusion and a circular protrusion with a height of 0.25mm, the circular protrusion and the circular protrusion are respectively tangent to the upper and lower surfaces of the nut body which are square, and the circular protrusion and the circular protrusion are respectively tangent to the square upper and lower surfaces of the nut body. The protrusion and the circular protrusion are provided with a through hole in the middle and penetrate through the nut body. The opening of the through hole is provided with a chamfer of 30°, and the inner wall of the through hole is provided with a thread. There are several strip-shaped protrusions from the circumference inward to the opening of the through hole, and a number of strip-shaped grooves are arranged from the opening of the through hole outward to the circumference of the circular protrusion. There is a chamfer of 15° extending outward to the prism of the nut body.
