| 1¡¢ The function of railway track fastener system railway rail fastener is a part used to combine rail and sleeper (or other types of under rail foundation) on track, also known as intermediate joint part. Its function is to fix the rail on the track pressing plate, adhere to the track gauge and prevent the rail from moving vertically and horizontally relative to the sleeper. The rail fastening system is divided into three parts: spring clip fastening system, fastening plate fastening system and spring strip fastening system. 2¡¢ Fastening system classification: fastening system is a kind of track fastening system. The track pressing plate manufacturer belongs to rigid fastening system. At present, KPO series are mainly used abroad, and there are mainly the following track fastening at home and abroad: At present, the fasteners used in China's concrete sleepers are all inseparable. Except for the bolt plate, 63 and 70 type plate fasteners developed in the early stage, they are all elastic fasteners. Due to the limited production level at that time, type 63 gusset plate fastener has no sulfur anchoring skills, so it can only embed wooden bolts in concrete sleepers, screw in bolt studs, and provide the combination of fasteners and sleepers. This type has been in the past and is now hard to see. The type 70 gusset plate fastener is of shoulder type, which is suitable for 50 and 43kg / M rails. The rail gauge can be adjusted by using gusset plate to press the rails and replacing gusset plates of different numbers. The combination of screw nails and sleepers adopts the sulfur anchoring form, and the wooden bolts are eliminated. At present, the newly-built railway is rarely laid and only used for maintenance of the existing line. The rigid gusset plate shall be used for the bolt gusset plate fastener, 63 type gusset plate fastener and 70 type gusset plate fastener. The concrete sleeper shall be provided with a shoulder. The bolt for fastening the gusset plate or the clamp plate fixed in the reserved hole of the concrete sleeper shall be screwed into the wooden sleeve embedded in the sleeper from the lower part, or the sulfur anchor shall be used to anchor into the reserved hole of the concrete sleeper. This kind of fastener has poor elasticity and large reduction of buckle pressure rate, which has been eliminated in the main line. 3¡¢ The production quality of fastening plate and fastener ensures that Changshu Sanyi metal products Co., Ltd. produces various track pressing plate manufacturers at home and abroad, mainly including die forging production process and casting production process.
