Abstract
The invention discloses a process for producing a modular sleeper beam for a railway carriage, which comprises the following steps of: welding a lower cover plate of the sleeper beam, a web plate, an inner clapboard and an air seat into a whole; welding anti-snake movement damper mounting beams at left and right ends of the sleeper beam; welding first and second transverse beams behind the sleeper between the anti-snake movement damper mounting beams on the rear of the sleeper beam; turning the sleeper beam, and welding an air spring base plate, a center plate mounting base plate and a vertical damper seat on the lower cover plate of the sleeper beam; and conveying a sleeper beam module to a ,machining center, and machining an air spring mounting surface, a center plate mounting surface and an anti-snake movement damper mounting surface. The sleeper beam, the first and second transverse beams behind the sleeper and the anti-snake movement damper mounting beams are welded to form an integral module, the integration degree is high, and the production efficiency is improved. After the whole module is subjected to assembly welding, the air spring mounting surface on the lower cover plate of the sleeper beam, the center plate mounting surface and the anti-snake movement damper mounting surface are subjected to unified machining and molding in the sleeper beam machining center; therefore, the machining accuracy of various mounting surfaces is guaranteed.
Description
Technical field
The present invention relates to a kind of passenger train sleeper beam modular structure, belong to passenger train Undercarriage structure technical field.
Background technology
China railways underframe of coach steel construction generally adopts girder construction in the nothing at present; The sleeper beam module only comprises the sleeper beam part; Do not form an integral body with pillow floor side member and anti-snakelike damper mounting rail; Because anti-snakelike shock absorber bearing installed surface is higher with respect to the Geometrical Tolerance Principle of sleeper beam lower cover, it is higher therefore underframe always to be assembled welding requirements.Simultaneously; Because the existence of position longitudinal beam in the car of pillow back; After coupler force is delivered to sleeper beam along draw beam, can not be delivered to the underframe side bar smoothly along sleeper beam, but continues to transmit backward along resting the head on back car longitudinal beam; Thereby cause the terminal corrugated floor stress of longitudinal beam superelevation, and along with the longitudinal beam lengthening constantly transmits backward.For overcoming the above problems, need a kind of brand-new sleeper beam structure and processing technology thereof.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, and a kind of passenger train modularization sleeper beam production technology is provided; Its machining accuracy is high, and efficient is high, realizes the module suffixation of a nonsyllabic "r" of sleeper beam; Change the bang path of coupler force, solve the too high problem of pillow back corrugated floor stress.
In order to solve above technical problem, passenger train modularization sleeper beam production technology provided by the invention is characterized in that comprising the steps:
The first step, on formal dress welding tire, with sleeper beam lower cover, web, internal partition, gas seat form, assembly welding is integral;
Second step, at the anti-snakelike damper mounting rail of sleeper beam right ends welding;
The 3rd step, at the sleeper beam rear, welding pillow back first crossbeam, pillow back second crossbeam successively between the anti-snakelike damper mounting rail;
The 4th goes on foot, sleeper beam is overturn, and welding air spring backing plate, cartridge are installed the vertical shock absorber bearing of backing plate on the sleeper beam lower cover;
The 5th step, the sleeper beam module that assembly welding is good are delivered to the sleeper beam Mechanical Processing Center; Under anti-dress state; Air spring backing plate on the sleeper beam lower cover, cartridge are installed backing plate, the unified processing of vertical shock absorber bearing, process air spring installed surface, cartridge installed surface, anti-snakelike shock absorber bearing installed surface.
The present invention is fixing with anti-snakelike damper mounting rail welding with sleeper beam, pillow back first crossbeam, the pillow back second crossbeam three, forms a monoblock type module, and this module can be carried out Assembling Production under car, and modularization, integrated degree height have improved production efficiency.Whole module groups postwelding, air spring installed surface, cartridge installed surface, anti-snakelike shock absorber bearing installed surface are unified machine-shaping at the sleeper beam Mechanical Processing Center, thereby are guaranteed the machining accuracy of each installed surface on the sleeper beam lower cover.The modularization sleeper beam that the present invention produces has been cancelled the pillow floor side member; After coupler force is delivered to sleeper beam; Disperse to both sides along sleeper beam, anti-snakelike damper mounting rail is delivered to the underframe side bar behind bilateral pillow, changes the bang path of coupler force; Thereby solved the problem of pillow back corrugated plating stress superelevation, helped the body construction Intensity Design; Simultaneously also reduce underframe weight, helped light-weighted car body design.
It is thus clear that, ingenious conception of the present invention, assembly precision is high, and production efficiency is high, and can improve body construction intensity.The present invention will be widely used in field of track traffic, have good market prospects.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a passenger train modularization sleeper beam structural representation of the present invention.
The specific embodiment
The passenger train modularization sleeper beam production technology of present embodiment comprises the steps:
The first step, on formal dress welding tire, sleeper beam lower cover, web, internal partition, gas seat are formed assembly welding are integral;
Second step, at the anti-snakelike damper mounting rail 21,22 of sleeper beam 1 right ends welding;
The 3rd step, at sleeper beam 1 rear, anti-snakelike damper mounting rail 21, welding pillow back first crossbeam 3, pillow back second crossbeam 4 successively between 22;
The 4th goes on foot, sleeper beam is overturn, and welding air spring backing plate 61,62, cartridge are installed backing plate 7, vertical shock absorber bearing 81,82 on sleeper beam 1 lower cover 5, and vertical shock absorber bearing 81,82 is welded on the sleeper beam lower cover of anti-snakelike damper mounting rail 21,22 belows;
The 5th step, the sleeper beam module that assembly welding is good are delivered to the sleeper beam Mechanical Processing Center; Under anti-dress state; Air spring backing plate on the sleeper beam lower cover 61,62, cartridge are installed backing plate 7,81, the 82 unified processing of vertical shock absorber bearing, process air spring installed surface, cartridge installed surface, anti-snakelike shock absorber bearing installed surface.
Except that the foregoing description, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
