Service HotlineShaft retaining ring (hereinafter referred to as retaining ring) is a very common part and is widely used in shaft parts. The existing solution for pressing the retaining ring is: place the retaining ring sleeve in the chamfering section or the guiding section of the shaft head, and then use an indenter whose inner hole diameter is larger than the diameter of the shaft head to press the retaining ring into the groove, and then press the retaining ring into the groove through the shaft head. The retaining ring is combined with the slot to prevent the indenter from continuing to move downward.
If you are installing rivet nuts specially, you can use a grinder, use a rivet machine, if you are a non-professional, you can directly install a few, and then tap with an awl. Rivet equipment (manual or pneumatic) cannot be used in the field of fastening using hammers to pull rivet nuts. It is widely used and is mainly used in the assembly of electromechanical and light industrial products such as aviation, furniture, automobiles, instruments, machinery, and decoration. Of course, it is more common than the rivet nut, and it is often difficult to distinguish.
Ordinary T-bolts, the bolt head is rectangular, the screw part and the bolt head are T-shaped, and the width of the head is smaller than the width of the opening part of the T-slot, so that the head of the T-bolt can extend from the length of the T-slot. Insert the T-slot into the T-slot at any position in the direction. When the workpiece needs to be fixed, turn the T-bolt 90 degrees so that the length of the head is perpendicular to the T-slot, hook the inside of the opening of the T-slot, and screw it by tightening The nut on the T-bolt threaded rod holds the workpiece in place. The T-bolt of this structure can easily connect the bolt and the base piece quickly, and is widely used, but there are also some shortcomings, due to the contact area between the head of the T-bolt and the inner side of the opening of the T-slot. If it is too small, the frictional resistance is correspondingly small. On the one hand, the bolts are easy to follow the rotation during the process of tightening the nut. Unreliable.
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.
Building aluminum alloy formwork is a new type of building formwork, which conforms to the four sections and one environmental protection policy. It is economical, fast, high-quality and environmentally friendly. Its application is of great significance to building energy conservation and environmental protection. The aluminum template is filled with aluminum template pins. However, the pins in the prior art have low connection strength during use, which is likely to cause the hole to be repaired weakly.
