Abstract
The invention belongs to the field of cold stamping process and in particular relates to a process for forming an inner automobile longeron plate and an outer automobile longeron plate at the same time. The process comprises the following steps of: firstly respectively falling materials for an inner frame longeron plate and an outer frame longeron plate; then welding the inner frame longeron plate and the outer frame longeron plate with materials fallen together according to an assembling position; and finally placing the inner frame longeron plate and the outer frame longeron plate which are welded together into a longeron forming die to be subjected to forming, wherein welding adopts resistance welding. The process disclosed by the invention can avoid the problem that assembling is difficult as respective forming hole positions of the inner longeron plate and the outer longeron plate are not aligned, and an assembly gap is small, thus bending strength of a longeron is improved, investment cost of the forming die is reduced and production cost is reduced.
Description
Technical field
The invention belongs to the cold punching technology field, relate in particular to a kind of automobile longitudinal girder inner and outer plates forming technology simultaneously.
Background technology
General traditional handicraft, automobile frame longeron inner and outer plates are blanking, shaping separately separately.Cause longeron inner and outer plates pilot hole hole site to misfit after the shaping easily, cause rivet welding assembling difficulty.And the inner and outer plates profile also can misfit and cause the fit-up gap big, and the bending strength of longeron is cut down in the fit-up gap conference.Shaping needs design two molds separately, needs to increase the production cost of investment.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of automobile longitudinal girder inner and outer plates forming technology simultaneously is provided.
In order to realize the object of the invention, technical scheme of the present invention is:
A kind of automobile longitudinal girder inner and outer plates is forming technology simultaneously, operates according to following steps:
The inside and outside plate of longitudinal beam that
will fall to getting well then separately welds together according to the position of assembling;
The inside and outside plate of longitudinal beam that
will weld together is at last put in the stringer forming mould and is shaped.
The said resistance welded that is welded as.
Beneficial effect of the present invention is: avoided the longeron inner and outer plates separately shaped hole not contraposition of position cause the problem of assembling difficulty, and the fit-up gap is also very little, improves the bending strength of longeron, reduces the shaping dies cost of investment and also reduces production costs.
Description of drawings
The longeron inner and outer plates sketch map of Fig. 1 for welding together by the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Embodiment: referring to Fig. 1.
A kind of automobile longitudinal girder inner and outer plates is forming technology simultaneously, operates according to following steps:
The inside and outside plate of longitudinal beam that
will fall to getting well then separately welds together according to the position of assembling;
The inside and outside plate of longitudinal beam that
will weld together is at last put in the stringer forming mould and is shaped.
The said resistance welding method that is welded as of step
.
Operating instruction: be superimposed upon good longitudinal beam inner panel 2 materials that fall on longitudinal beam outside plate 1 material, then through electric resistance welding, the several solder joints 3 of welding between the inside and outside plate of longitudinal beam are put into shaping together in the stringer forming mould then.
What embodiments of the invention were announced is preferred embodiment, but is not limited thereto those of ordinary skill in the art; Very easily, understand spirit of the present invention, and make different amplifications and variation according to the foregoing description; But only otherwise break away from spirit of the present invention, all in protection scope of the present invention.
Claims (2)
