Description
Technical field
The utility model relates to rail parts technical field, particularly relates to rail hook tongue.
Background technology
Existing lorry coupler tongue is owing to requiring and tension the connectivity of its structure, the performance requriementss such as Resisting fractre are stronger, so in the process of producing it, the first roughcast of general employing, and through heating for multiple times, the method of forging again is forged,---heating---base---post bake---preform---trimming---polishing---three heating---finish-forging shaping---trimmings that concrete processes process is: blanking, the method is that process is comparatively complicated, operation is various, intermediate link is many, the factor of behavior adjustment management and control is larger, manufacturing schedule is difficult to ensure, and because the planform of hook tongue is comparatively complicated, higher to the technical requirements of workman, roustabout is in manufacturing engineering, fraction defect is higher.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides rail hook tongue, its object is to the production process and its structure that improve simplification hook tongue, to reduce its manufacture difficulty and to shorten the manufacturing cycle, and ensure its intensity, facilitate it to install when connecting and using, but ensure again the requirement of its functional intensity, stretch-proof performance simultaneously.
The technical scheme that the utility model adopts is: rail hook tongue, comprises insertion section and connecting portion, be provided with fixed part between insertion section and connecting portion, connecting portion is crotch shape, fixed part is cylindrical, and fixed part center position also arranges porose, thus provides the attachment point of hook tongue; Insertion section is connected to the periphery perpendicular to fixed part, and connecting portion is bent to form hook part to fixed part direction, and the curved chamber of hook part provides the connection space of the part be connected with hook tongue.The hook tongue portion of being fixed of the present utility model is arranged between insertion section and connecting portion, hook tongue is fixed therein on a joint train case, then corresponding site insertion section being stretched into again this joint train railway carriage is fixed further, plays good fixation, enhances the intensity of himself; Finally connecting portion structure is lived an other joint train railway carriage, and to connect, because connecting portion is bent to form hook part to the direction of fixed part, there is stronger containing performance, and structure is simple, easily forges.Hook tongue structure of the present utility model, be made up of simple three stage structure, the planform of each section is regular shape, when forging and molding, is shaped and repeatedly forges without the need to heating for multiple times, after only needing blanking, carry out preliminary profile blocking, and the finish-forging in later stage, the hook ligulate that can be shaped shape, operation is simple, and is shaped without the need to heating for multiple times.
Preferably, hook part position is also provided with connecting bore, thus convenient hanger tongue can place attaching parts, is linked together by two joint train railway carriages.
Preferably, the outside face of hook part is also provided with lightening hole, thus under the prerequisite ensureing hook tongue Functional Requirement, alleviates its weight.
Preferably, the position, both ends of fixed part is also provided with groove, thus stay hook tongue easily.
Preferably, insertion section is fan-shaped, and its covering of the fan both sides are also provided with jut, to strengthen insertion section.
Compared with prior art, the beneficial effects of the utility model are: the hook tongue portion of being fixed of the present utility model is arranged between insertion section and connecting portion, hook tongue is fixed therein on a joint train case, then corresponding site insertion section being stretched into again this joint train railway carriage is fixed further, play good fixation, enhance the intensity of himself; Finally connecting portion structure is lived an other joint train railway carriage, and to connect, because connecting portion is bent to form hook part to the direction of fixed part, there is stronger containing performance, and structure is simple, easily forges.Hook tongue structure of the present utility model, be made up of simple three stage structure, the planform of each section is regular shape, when forging and molding, is shaped and repeatedly forges without the need to heating for multiple times, after only needing blanking, carry out preliminary profile blocking, and the finish-forging in later stage, the hook ligulate that can be shaped shape, operation is simple, and is shaped without the need to heating for multiple times.Further, during fabrication, only need follow following technique can obtain qualified hook tongue to hook tongue of the present utility model: blanking, heating, blocking, finish-forging, trimming.
The utility model improves the production process and its structure that simplify hook tongue, to reduce its manufacture difficulty and to shorten the manufacturing cycle, and ensure that its intensity, facilitate it and install when connecting and using, but in turn ensure that the requirement of its functional intensity, stretch-proof performance simultaneously.
