Description
Technical field
The invention belongs to the hollow forming aluminium section implant of rail vehicle big cross section and its using method field, and in particular to
A kind of cavity filling device and its using method for hollow aluminium section bar bending process.
Background technology
As shown in Figure 1 to Figure 3, which includes the hollow molded cavity 1-1 of rectangle and many to the initiating structure of the hollow aluminium section bar of big cross section 1
Individual skirt border structure 1-2, hollow aluminium section bar 1 are needed through machining of bending, and are bent into the curved shape shown in Fig. 4 to Fig. 5.
To ensure that hollow molded cavity 1-1 keeps the cross-sectional outling of its rectangle in press bending process, need to fill to the inside of which
Molding implant.
At present, the hollow forming aluminium section implant of big cross section mostly is fluid corundum, using fluid corundum as filling
During thing, need hollow molded cavity 1-1 one end is closed using welding manner, corundum is inserted from the other end of hollow molded cavity 1-1, gold
Wedged the end of hollow molded cavity 1-1 after emery end-of-fill by operator with timber wedge so as to form near closed hollow ring, prevent Buddha's warrior attendant
Sand flow goes out, and timber wedge is pulled out after terminating by molding, then corundum is poured out.
However, one end that sealing is soldered on hollow molded cavity 1-1 need to also be beaten after press-bending by said method again again
Open, this process wastes time and energy, and be easily caused the welding deformation of 1 workpiece of hollow aluminium section bar.Additionally, by the experience of operator
Judge that the method for the wedging depth of timber wedge is difficult to accurately weigh the density of corundum implant in hollow molded cavity 1-1, to operator
Experience and skill set requirements are high, and personal error is larger, cause the packed density of corundum filling to be difficult to obtain reliable guarantee, and then
Cause the press-bending difficult quality precise control of sky aluminium section bar, defect rate and scrappage high.
The content of the invention
In order to solve the existing section bar bending process using fluid corundum as the hollow forming aluminium section implant of big cross section
Die cavity need to be sealed bending, and be opened die cavity sealed end time after press-bending terminates again by method, and its process steps is numerous
It is trivial, waste time and energy, and easily make the generation welding deformation of hollow aluminium section bar.And by operator experience to filling up Buddha's warrior attendant
In the die cavity of sand, the method personal error of the wedging depth of timber wedge is larger, and causing the packed density of corundum filling to be difficult to obtain can
By ensureing, the press-bending difficult quality precise control of sky aluminium section bar is in turn resulted in, the high technical problem of defect rate and scrappage, this
