Service HotlineMost of the existing screws use an integral metal structure, and there are still some problems, such as large weight, high cost of materials, wear resistance, hardness, rust resistance, corrosion resistance, high and low temperature resistance, brittleness, toughness, etc. Many occasions cannot meet the needs of production, and further improvements are needed to improve production efficiency, reduce costs, improve safety, and prolong the service life of screws.
According to an aspect of Guangdong Yueluo Hardware Industry Co., Ltd., a rivet insertion mechanism is provided, including a pressure cylinder, a pressure shaft, an insertion nozzle, a bottom plate, a fixing block and a rivet fixing mechanism, wherein one end of the pressure shaft is connected with the pressure cylinder, and the other end is connected with the pressure cylinder. The insertion nozzle is connected, the fixing block is sleeved on the pressing shaft, and is fixedly connected with the bottom plate, the rivet fixing mechanism is installed on the bottom plate, and the insertion nozzle extends into the rivet fixing mechanism and can extend from the rivet fixing mechanism.
1. For the lock ring of the anti-dropping nut, snap the ring into the lock, tighten the lock claw, and the lock claw is fastened into the thread. The lock claw does not have thread characteristics, and it is difficult for the nut to be threaded during the vibration process of the machine. If it fails, the locking claw acts as a tightening nut, but it does not have the problem of loosening itself like the locking nut.
met a customer before, and the stainless steel screws needed by the company need to be prevented from loosening. Simply put, the stainless steel screw should be used on the product material so that the stainless steel screw will not fall off lightly. The screws are required to be more tightly connected with the product material. For the solution of stainless steel screw anti-loosening, there are two solutions. Next, the following two solutions to prevent loosening of stainless steel standard parts are presented. The first is to use the resilience of special materials, such as engineering resin materials, which have good resilience. Attach it to the stainless steel screw thread. Make it mechanically rub against the nut, or material product. Generate vibration and absolute resistance. Completely solve the problem of loose screws. The second, simply put, is to apply a layer of glue on the thread of the stainless steel screw, the so-called dispensing. This glue is called drop-resistant glue. This glue has good properties such as high stickiness and non-toxicity. This glue is applied to stainless steel screws, and when dry, it adheres extremely well. The stainless steel screw thread can be combined with the nut thread, or after the product threaded hole is joined, resulting in a super tightening effect. Play a super good anti-loosening effect.
Pins are widely used. In the connection of the rotating mechanism of two moving components, such as the crank mechanism, the turning mechanism, the connection between the hydraulic cylinder and the moving parts, the pins are used. kind. In order to ensure the normal use of the running equipment and prevent the cylindrical pin from slipping out and falling off during use, some anti-falling methods are usually used at the head of the pin, such as 1. Drill holes and insert cotter pins to prevent the pins from slipping out; 2. The external thread is tightened with a nut to prevent the pin from slipping out; 3. The slot is clamped with a circlip to prevent it from slipping out, etc. These measures make the cylindrical pin very practical in the case of infrequent disassembly and assembly, but in the actual use of the field, in order to prevent the collision of some equipment during each troubleshooting or maintenance, the pin needs to be pulled out and turned up, etc. After the failure or maintenance is completed, put down and then insert the pin to restore, this process will bring trouble to the actual operator. For example, special tools must be brought with you every time you disassemble and assemble the pin, and the split pin or the circlip is easily damaged after repeated disassembly and assembly. , In order to save trouble, the operator sometimes uses iron wire to thread or fasten it instead, and even does not remove the pin for the sake of speed and convenience, which is easy to cause damage to the equipment when dealing with faults.
