Service Hotlinedouble-headed pin puller includes a slider hammer and a sliding rod, two ends of the sliding rod are respectively provided with different types of pin-pulling parts, the pin-pulling parts are threadedly connected with the sliding rod, and the sliding rod is also provided with There is a sliding rod limit block, and the sliding rod is slidably connected with the slider hammer. The double-headed pin puller can install two types of pin-pulling heads at the same time, and can pull out two different types of pins. It is easy to use and has high work efficiency. Disadvantage: Single function, cannot be used to install pins.
Two combination screws are also called two combination screws. As the name suggests, it consists of a screw with a spring washer or only a flat washer. After the thread rolling, the two components are combined together. Two combination screws are available in iron and stainless steel. For iron, there are screw materials such as screw wire 1010, 1018, 10B21, etc. The general iron pier needs to be electroplated, and electroplating is divided into environmental protection and ordinary. For example, there are environmentally friendly color zinc, environmentally friendly blue zinc, white zinc, color zinc, white nickel and other electroplating. Stainless steel two combination screws. The material is stainless steel 304.
Bearings are an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Every time the locomotive is repaired, the end cover of the axle box needs to be disassembled, the axle head is tested for flaws and the bearing is supplemented with grease, which involves the disassembly and assembly of the axle box bearing retaining ring. The existing disassembly method is to use the traditional method of inserting two tongue pins into the gap between the bearing retaining ring and the axle box to pry left and right, and slowly separate it from the axle head. Because the clearance between the bearing retaining ring and the shaft head is small, and the adhesive force generated by the grease in the axle box is large, if the disassembly method is not appropriate or the force is not uniform, it will cause certain damage to the axle box body and the bearing retaining ring or jam. It is easy to cause damage to the bearing, and there is also the possibility of damage to the disassembly and assembly tools, so the safety risk is high, and each disassembly and assembly of the bearing retaining ring is time-consuming and laborious, labor-intensive, low-efficiency, and increased maintenance costs.
The main operation method of the embedded knurled copper nut of the lock nut is injection molding. After heating, it is embedded into the plastic part or directly injection molded. If injection molding is used, the melting point of P/NYLOY/PET is above 200°C. , After the embedded nut is hot melted into the plastic part, the temperature rises rapidly. After injection molding, the plastic body rapidly cools and crystallizes and hardens. If the embedded nut temperature is still at a high temperature, it may fall to the place where the copper nut contacts the plastic part. Start to loosen or crack. Therefore, copper nuts are used instead of carbon steel nuts in the injection molding of embedded nuts.
The anchor bolts of some metallurgical industrial equipment are detachable, that is, the anchor bolts are not directly anchored in the foundation concrete, but anchored in the T-bolt sleeve (T-bolt sleeve hereinafter referred to as sleeve) , The sleeve is constructed together with the foundation and anchored directly in the foundation. The T-bolt is inserted into the sleeve when the equipment is installed, and the T-bolt can be removed from the sleeve when the equipment is replaced.
