The vibration component is driven by the eccentric circle to realize the rapid vibration of the hammer bar up and down to tamp the road surface; Features: It is a high-precision, high-strength shaft part with eccentric circle. The shaft has coaxial mounting circle (used for mounting bearings, oil seals, mounting to mounting seats, etc.) and eccentric circle. The requirements for items such as excircle roundness, cylindricity, size, roughness, eccentric circle position, etc. are very high. Process requirements: the blank is generally made of steel bars or forgings, the main processes include: roughing-heat treatment-semi-finishing-grinding and other processes; the main processing equipment is CNC lathe, CNC cylindrical grinder, quenching equipment and other equipment. Key testing items: surface roughness, roundness, cylindricity, coaxiality, hardness, metallographic and other items; Key testing equipment: large and medium-sized precision coordinate measuring machines, hardness testers, metallographic microscopes and other high-precision testing equipment.

Compaction paver accessories include supports, supports, arms, rims, grounding plates, counterweights, etc. They are used for compaction paver products of paving engineering machinery, mostly special and special-shaped casting parts, and are installed through processing and connecting surfaces and mounting holes. Features: It belongs to special casting parts, the processing parts mainly have surfaces and holes, and the non-mounting surfaces are casting surfaces; Process requirements: Blanks are generally cast from cast iron, the main process includes: casting-sandblasting-milling plane-drilling and other processes; the main processing equipment has processing center and other equipment. Key inspection items: surface roughness, hole position, flatness, symmetry and other items; Key inspection equipment: large and medium-sized precision coordinate measuring machine and other equipment.

Railway accessories hammer strip application: used for a paving engineering machinery compaction paver (also called vibratory roller, road roller, road paver, etc.) products, through rapid and repeated up and down vibration hammering, the road surface is flattened and compacted, belonging to a long plate-shaped part; Features: It belongs to a high-precision plate-shaped part, with thin and long workpieces, high straightness and flatness requirements, and high surface hardness and layer depth requirements; technical requirements for hammer bars for railway accessories: blanks are generally made of square steel. The main processes include: blanking-heat treatment pretreatment-milling (multiple planes and inclined planes)-induction quenching and tempering-straightening-grinding-milling groove-drilling, tapping-fine straightening and other processes. The main processing equipment includes processing center, straightening machine, quenching equipment, surface grinder and other equipment. Railway accessories hammer bar key testing items: surface roughness, surface hardness, hardened layer depth, flatness, straightness and other items.
