Abstract
The utility model discloses a dovetail-shaped corrugated plate at the bottom of a stainless steel railway passenger car. The corrugated plate comprises a body, wherein the upper end of the body is provided with dovetail-shaped slots which are continuously and uniformly arranged, and the width of the body is at least 800 meters and is specifically 845 meters. The dovetail-shaped corrugated plate at the bottom of the stainless steel railway passenger car is made of a sectional material of which width is at least 800 meters; the process engineering that two dovetail-shaped corrugated plates with the respective width no more than 500 meters are welded together is cancelled; the defects of edge warping, corrugating and reduced rigidity brought about in the process of the welding process are cancelled; in addition, the steps of the welding process as well as a raw material at the original welded overlapping part of the two corrugated plates are saved, the manufacture efficiency is improved, the production cost is reduced, the appearance quality is further improved, and the flatness is improved.
Description
Technical field
The utility model relates to the structure of a kind of corrosion-resistant steel trolley coach bottom dove-tail form corrugated plating, belongs to the carbody technical field of structures.
Background technology
The corrosion-resistant steel trolley coach has advantages such as in light weight, that antiseptic property good, service expenditure is low, and its market outlook are boundless.As shown in Figure 1, in the stainless steel car body structure, owing to receive the restriction of corrosion-resistant steel clod wash technical merit, traditional passenger vehicle bottom corrugated plating mechanism is that the dove-tail form corrugated plating 1 that every width is no more than 500 person of outstanding talent's rice is welded at the A place with another dove-tail form corrugated plating 2.In A place welding process, warpage and wave can appear at the welding end of dove-tail form corrugated plating 1 and dove-tail form corrugated plating 2, and mechanism's integral rigidity, outward appearance and planeness all are affected greatly.
Summary of the invention
The utility model technical matters to be solved provides a kind of ability solution original bottom corrugated plating because passenger vehicle bottom, the novel stainless rail road dove-tail form corrugated plating of mass defects such as the limit portion warpage that welding brings, wave, weldering trace.
The technical scheme of the utility model is:
A kind of corrosion-resistant steel trolley coach bottom dove-tail form corrugated plating comprises body, and the upper end of body is provided with and is evenly distributed dovetail furrow continuously, and the width of body is at least 800 millimeters.
The width of body can be 845 millimeters.
Beneficial effect: the corrosion-resistant steel trolley coach bottom dove-tail form corrugated plating employing width of the utility model is at least 800 millimeters a section bar; Cancel the process engineering that two width is no more than 500 millimeters dove-tail form corrugated plating weld together, eliminated the defective that the limit portion warpage that welding procedure is brought, wave, integral rigidity reduce; And save the welding process step and practiced thrift the raw MAT'L of former welding stack place, improve manufacturing efficient, practiced thrift productive costs.Also improve presentation quality, improved planeness.
Description of drawings
Fig. 1 is the structural representation for existing corrosion-resistant steel trolley coach bottom dove-tail form corrugated plating;
Fig. 2 is the structural representation of the utility model.
Among the figure: 1-dove-tail form corrugated plating, 2-another dove-tail form corrugated plating, 3-body, 4-dovetail furrow.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of corrosion-resistant steel trolley coach bottom dove-tail form corrugated plating comprises body 3, and the upper end of body 3 is provided with and is evenly distributed dovetail furrow 4 continuously, and the width of body 3 is at least 800 millimeters.
The width of body can be 845 millimeters.
As shown in Figure 2; The corrosion-resistant steel trolley coach bottom dove-tail form corrugated plating employing width of the utility model is at least 800 millimeters a section bar; Cancel the process engineering that two width is no more than 500 millimeters dove-tail form corrugated plating weld together, eliminated the defective that the limit portion warpage that welding procedure is brought, wave, integral rigidity reduce; And save the welding process step and practiced thrift the raw MAT'L of former welding stack place, improve manufacturing efficient, practiced thrift productive costs.Also improve presentation quality, improved planeness.
Deformation velocity slowed down when an independent width of the utility model needed moulding for the realization of at least 800 millimeters dovetail corrugated plating; And because fabric width is big, limit portion is bigger than middle part elastic recoil, and the dovetail furrow moulding of limit portion should be slower than the generation that the middle part dovetail furrow could be controlled limit portion wave preferably; Need more passage than existing dove-tail form corrugated plating during moulding; Shaping resistance is bigger; Requirement has sub-quantity to surpass 40 the shaping machine set and the driven by motor of corresponding enough power, can satisfy the requirement of this shaping machine set fully according to the manufacture level of domestic cold bending molding equipment now.
