Abstract
The utility model relates to a cylinder component for a retarder in a railway yard of a marshalling yard, in particular to a piston blank with a two-body embedded type end surface welding structure for a retarder. The piston blank is characterized in that a piston head is welded with a piston handle; the piston head is provided with an annular groove and a center stem column; the piston handle is provided with a hollow back taper; outer end surfaces of the piston head and the piston handle are welded after the piston head and the piston handle are jogged. The piston blank has the advantage that a welding line keeps away from a retaining ring groove of a piston finished product. After the retaining ring groove is machined in the outer diameter, the welding strength in the position of the welding line can not be reduced, so that breakage can not occur in the position of the retaining ring groove when the piston blank is used, and a serious accident that the retaining ring groove is broken formerly is fundamentally avoided. The welding operation is more convenient, the quality is easier to guarantee, and the risk of infirm welding is also greatly reduced. In addition, as the operation is convenient, the production efficiency is greatly improved simultaneously.
Description
Technical field: the utility model relates to the oil cylinder assembly parts of the decelerating that uses on a kind of marshaling yard marshalling yard, is specially decelerating with the embedded end face welded structure of two bodies piston blank.
Background technique: high-load speed reducing support is a kind of for the hydraulic speed regulating device on the marshaling yard hump yard.When the target compartment acts on the oil cylinder assembly parts, relative movement by piston and oil cylinder, and the switch motion that is installed in the valve plate on its top, the fuel-air mixture of oil cylinder assembly parts inside concentrates in the axis hole of its underpart by six Kong Hui of piston, valve rod is produced pressure-acting and realizes speed-regulating function, thereby finish decelerating is put the compartment to sauntering expection speed governing effect.This piston is one of core part that affects product performance.It not only acts on important, and technical requirements is high, and complex structure, and manufacture difficulty is large.The former welded structure form of this piston is to be adopted the method for docking by piston head and piston handle, weld seam is placed on the external diameter surface of weld assembly.When assembly is processed as finished product, need at circlip groove of welding external diameter surface processing, because the physical dimension restriction, this circlip groove is very near apart from weld seam, a part of car of weld seam may be fallen during the processing circlip groove, reduced like this weld strength at weld bond place, and it is concentrated easily to produce stress.Frequently under the impact force action of heavy load, be everlasting weld joint or circlip groove place fracture cause security incident in marshalling yard.For example, at the Guangxi Yulin station many fractures occuring once, allows the lake way station also have fracture to occur in grand celebration.Therefore, the intensity that conscientiously improves this part just becomes very urgent.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, with low cost, working life of whole decelerating and performance are improved and the decelerating that improves with the embedded end face welded structure of two bodies piston blank.The purpose of this utility model realizes by following technological scheme: it comprises piston head, piston handle, it is characterized in that: described piston head and piston handle are to be welded to connect, piston head is provided with described annular groove, center stem post, piston handle is provided with hollow back taper, and the two is welded to connect described piston head and piston handle in the weld joint, exterior edge face after chimeric.Piston head is provided with described positioning spigot in the small end head place, and a mouthful end is designed to outside described groove; Piston handle is provided with the described locating shoulder that becomes Spielpassung with the piston head positioning spigot in large end, piston handle is provided with described inside groove in the outside, large termination.Beneficial effect of the present invention: 1, the utility model is innovated from weld assembly two body Placements and structure, weld seam is arranged on place, exterior edge face after the combination of piston head and piston handle, avoided the weakening effect of processing circlip groove butt welded seam, effectively strengthened the bulk strength of assembly, improve life-span and the safety reliability of whole decelerating, can thoroughly solve this piston at circlip groove place breakage problem.2, weld seam is opened at end face in the utility model, need not use the special fixture of spinfunction, and welding after can directly placing with the large end face location is highly stable reliable.Save clamping and take-down time, improved work efficiency.3, in the utility model weld seam is changed on the plane from the cylndrical surface, saved the time of rotational workpieces in welding process, more convenient operation welding.4, save material.
Figure of description: Fig. 1 is that the utility model structural principle section master looks schematic representation; Fig. 2 is the utility model piston head cross-section structure principle schematic; Fig. 3 is the utility model piston handle cross-section structure principle schematic.5 one circlip grooves.
Embodiment: it comprises piston head 1, piston handle 3, it is characterized in that: described piston head 1 and piston handle 3 are to be welded to connect, piston head 1 is provided with described annular groove 7, center stem post 6, piston handle 3 is provided with hollow back taper 4, and the two is welded to connect described piston head 1 and piston handle 3 in exterior edge face weld seam 2 places after chimeric.Piston head 1 is provided with described positioning spigot 8 in the small end head place, a mouthful end is designed to outside described groove 9; Piston handle 3 is provided with the described locating shoulder 10 with 8 one-tenth Spielpassung of piston head 1 positioning spigot in large end, piston handle 3 is provided with described inside groove 11 in the outside, large termination.The embedded welded structure of piston head two bodies, its assembly two bodies are: piston head 1, piston handle 3, piston head 1 are with annular groove 7 and center stem post 6, and piston head 1 processes positioning spigot 8 in the small end head design, and a mouthful end is designed to outside groove 9; Piston handle 3 is with hollow back taper 4, is processed into the locating shoulder 10 with 8 one-tenth Spielpassung of piston head 1 positioning spigot in its large end, and piston handle 3 its outsides also are designed to inside groove 11.After the two erection welding, form the cylindrical weld seam part of width 1mm in the weld seam bottom, add groove 9 weld seam parts, increased the area of weld seam 2, strengthened the bulk strength of assembly, and made weld seam 2 get out of the way circlip groove 5.Guaranteed that weldquality is not affected by circlip groove.
