Abstract
The utility model relates to a rotary forged steel car coupler yoke which comprises a frame body, a cylindrical chamber and a pin hole, wherein the frame body is composed by a U-shaped forged steel frame and two forged steel lateral plates; the two forged steel lateral plates are welded on the two lateral edges of the front end of the U-shaped forged steel frame, respectively; the cylindrical chamber is positioned in the inner cavity at the head part of the frame body; and the pin hole is arranged on the bottom edge of the frame body. Since the high-strength alloy steel blank is taken as forging raw material, the inherent defect of the rotary forged steel car coupler yoke is greatly reduced and the overall mechanical performance is greatly increased, as compared with the prior art using steel castings. Additionally, the material of car coupler yoke is processed in the full-fiber texture through the forging and press-molding processes, so that the strength and the service life of the car coupler yoke are doubled. According to the tests, the fatigue strength of the rotary forged steel car coupler yoke is increased by 80% than the prior cast car coupler yoke, and the service life of the rotary forged steel car coupler yoke is increased by 3 to 4 times than the prior cast car coupler yoke. The rotary forged steel car coupler yoke has the advantages of reasonable structure, high mechanical strength, easy assembly and disassembly and long service life.
Description
Technical field
The utility model relates to the connecting device of railway truck, and particularly a kind of mechanical strength Gao Bingneng can make the rotary dump coupler forged steel coupler yoke in the lorry connecting device of lorry upset unloading under coupled condition, belongs to the connecting device of rolling stock.
Background technology
Hitch hook tail frame is a key components and parts in the railway vehicle coupler connecting device, directly finishes the transmission of longitudinal force between the vehicle.The hitch hook tail frame that uses on the past rolling stock is a steel casting always.Because defectives such as there is pore unavoidably in steel casting, is mingled with, shrinkage porosites, intensity is difficult to improve.In recent years, because railway is implemented speed-raising, heavy duty for improving transport capacity, the defective that casting hook tail frame is existed has exposed, in use too early appearance endurance crack, the brisement accident that takes place frequently is brought potential safety hazard to railway transportation, the safety of railway transportation needs have been difficult to adapt to, especially can be implemented in the rotary dump coupler hook tail frame on the vehicle that upset is unloaded under the coupled condition, because every train pull weight surpasses 20,000 tons, its stressed other various hitch hook tail frames that substantially exceed.
Summary of the invention
The purpose of this utility model mainly is for overcoming the weak point of above-mentioned existing hook tail frame, design a kind of rational in infrastructure, mechanical strength is high, the rotary dump coupler forged steel coupler yoke of easy to loading and unloading, long service life.
Rotary dump coupler forged steel coupler yoke of the present utility model comprises framework, cylindrical cavity and pin-and-hole, wherein, described framework is made up of U font forged steel framework and two blocks of forged steel side plates, two blocks of forged steel side plates are welded on respectively on the dual-side of U font forged steel framework front end, cylindrical cavity is located in the inner chamber of framework head, and pin-and-hole is located on the base of framework.Described U font forged steel framework and two blocks of forged steel side plates select for use the high strength alloy steel steel billet for forging raw material.It is other model steel billet of 25MnCrNiMOA steel billet or similar quality that described high strength alloy steel steel billet is selected model for use.
It mainly is owing to adopt high-intensity alloy steel for forging raw material that rotary dump coupler forged steel coupler yoke of the present utility model has outstanding advantage than traditional casting hook tail frame, its latent defect significantly reduces than steel casting, comprehensive mechanical performance greatly improves, again by forging, press processing can make hook tail frame material form full fiber structure, its intensity and service life significantly improve, and through evidence: its fatigue ratio casting hook tail frame improves 80%.Improve 3-4 doubly than casting hook tail frame service life.Be a kind of rational in infrastructure, mechanical strength is high, the rotary dump coupler forged steel coupler yoke of easy to loading and unloading, long service life.
Description of drawings
Accompanying drawing 1 is a hook tail mount structure scheme drawing of the present utility model;
Accompanying drawing 2 is left TV structure scheme drawings of accompanying drawing 1;
Accompanying drawing 3 is plan structure scheme drawings of accompanying drawing 1;
Accompanying drawing 4 is perspective view of hook tail frame of the present utility model;
Accompanying drawing 5 is hook tail frame of the present utility model and hitch hook tail coupled condition structural representation.
The specific embodiment
Accompanying drawing is non-limiting to disclose a specific embodiment of the present utility model, is further described as follows in conjunction with the accompanying drawings.
Referring to accompanying drawing 1-3,1 among the figure is U font forged steel framework, the 2nd, and the forged steel side plate, the 3rd, the forged steel side plate is welded on the weld seam on the U font forged steel framework front end side, the 4th, cylindrical cavity, the 5th, pin-and-hole.The frame structure of hook tail frame of the present utility model mainly is made up of U font forged steel framework 1 and two blocks of forged steel side plates 2, two blocks of forged steel side plates 2 are welded on respectively on the dual-side of U font forged steel framework 1 front end, cylindrical cavity 4 is located in the inner chamber of framework head, and pin-and-hole 5 is located on the base of framework.
When making framework, should select 25MnCrNiMOA high strength alloy steel steel billet for use is raw material, through the pulling cogging, by base, forge into the rectangular material that two heads have moon type circular arc, simultaneously produce the blind hole of a circle with mould with three flanges of rectangular material, the side cut shaping bends to U font forged steel framework 1 then.
Be cambered surface with two inboards again, the outside is that mid-plane, both sides are that the forged steel side plate 2 on inclined-plane is welded on respectively on the dual-side of U font forged steel framework 1 front end, and the head of U font forged steel framework 1 is welded into an osed top hollow cylinder shape.In order to guarantee that product design meets the weld defect grade is the I grade standard, can adopt instruments such as super sonic to carry out carrying out flaw detection, guarantees welding quality.
By machine up cylindrical cavity 4 is processed in the position of framework head dress turning set then, and circle is processed as through hole with the blind hole of three flanges forms pin-and-hole 5.At last forging hook tail frame is carried out modified heat treatment.Its spatial structure as shown in Figure 4.
During use, with the structural relation of hitch hook tail and hook tail frame bonded assembly running condition as shown in Figure 5, turning set 7 among the figure is contained in the cylindrical cavity 4 of framework 1 head, the pin-and-hole 5 of round pin 8 through being located at the framework base is inserted in the pin hole of turning set 7 and coupler butt 6, hitch 6 and turning set 7 are become one, and pin-and-hole lid 9 lids are contained in round pin 8 can not dropped out from pin hole.Hitch 6 and turning set 7 can rotate in the cylindrical cavity 4 of framework 1 head but can not break away from hook tail frame, and hook tail frame is mounted on the car body, when connecting by hitch between the vehicle, can make and not separate the effect of playing transmitting tractive power between the vehicle, can be again that axle relatively rotates with the connecting device, realize under coupled condition, can making certain lorry upset unloading, and do not influenced other vehicle.
