The technical scheme that the utility model can also be taked is:
The dual-side of described U-shaped pressing plate is fixedly connected with by bearing pin is detachable with the two sides, front and back of lower module.
The advantage that the utility model has and good effect are:
This press-bending frock by arranging cancave cambered surface A and cancave cambered surface B, arranging the convex globoidal A and convex globoidal B that coordinate respectively on lower module on upper module, achieve the one time punching molded of two bendings on track beam backplate, its mode of overlapping bending tool compared to existing employing two and carrying out twice pressing and bending in front and back, decrease the quantity of frock on the one hand, improve working (machining) efficiency on the other hand, preresearch estimates working (machining) efficiency at least improves 2 times; This frock forms rigidity location by U-shaped pressing plate to plate, form frictional force by the rank difference of the surface roughness of two cancave cambered surfaces and two convex globoidals to locate, these two kinds of locate modes combine, thus ensure that workpiece obtains precise positioning in press bending process, compensate for the deficiency of positioning precision difference in existing press bending process, and then also improve the compact dimensions precision of workpiece.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-3, two bending track beam backplate one-shot forming press-bending frock, comprise installation lower module 1 on the table and the upper module 2 of Bonding pressure machine.The convex globoidal A1-1 consistent with the Internal periphery face of the first bending part on track beam the backplate to be processed and convex globoidal B1-2 consistent with the Internal periphery face of the second bending part is respectively equipped with in two upper corners positions of lower module.In the position of upper-end part of driving between convex globoidal A and convex globoidal B of lower module, U-shaped pressing plate 3 is installed, the dual-side of U-shaped pressing plate is fixedly connected with the two sides, front and back of lower module are detachable, the spacing consistent with curved track beam guard plate thickness is provided with between the upper base inner surface of U-shaped pressing plate and the upper surface of lower module, by U-shaped pressing plate, plate is pressed on the upper surface of lower module like this, make plate in bent into shape process, not run-off the straight misplaces.The lower surface of upper module is respectively equipped with the cancave cambered surface A2-1 corresponding with convex globoidal A near the position of dual-side and the cancave cambered surface B2-2 corresponding with convex globoidal B, described cancave cambered surface A and cancave cambered surface B are consistent with the outer surface of the first bending part on track beam backplate to be processed and the outer surface of the second bending part respectively.Slot to make way 2-3 is provided with between cancave cambered surface A and cancave cambered surface B, the width of slot to make way is more than or equal to the width of U-shaped pressing plate, the degree of depth of slot to make way is more than or equal to U-shaped pressing plate deducts track beam backplate one-tenth-value thickness 1/10 from the height that lower module upper surface is stretched out, like this, when in the descending process of upper module, the upper end of U-shaped pressing plate is inserted into slot to make way gradually, avoids the generation of interference.The surface roughness of two cancave cambered surfaces is higher than the surface roughness 1-2 grade of two convex globoidals, like this in track beam backplate bent into shape process, make plate keep static with lower module all the time, and with upper module relative sliding, thus further ensure the precise positioning of plate in press bending process.
In said structure, the dual-side of described U-shaped pressing plate is fixedly connected with preferably by bearing pin 4 is detachable with the two sides, front and back of lower module are logical.Concrete, the two sides, front and back of the upper and lower module of the dual-side of U-shaped pressing plate are provided with the pin-and-hole matched, realize connecting by the bearing pin be inserted in pin-and-hole, adopt bearing pin plug-in mounting connected mode, facilitate the installation of plate and taking off of bent into shape part, have easy to operate and labour-saving advantage, in addition, U-shaped pressing plate is connected with also adopting bolt between lower module.
Adopt this press-bending frock to process track beam backplate, first by plate 1
,the upper surface of lower module is placed on according to prior scribing position; Then U-shaped pressing plate is withheld on plate, and by bearing pin or bolt, U-shaped pressing plate is fixedly connected with lower module; Then starting pressure machine carries out punching press, make upper module descending, cancave cambered surface A on upper module and cancave cambered surface B makes the both ends bending gradually of sheet material, when cope match-plate pattern goes downwards to the consistency of thickness of the distance between cancave cambered surface A and convex globoidal A and the distance between cancave cambered surface B and convex globoidal B and sheet material, the both ends of plate form two bendings consistent with two bending angles set respectively, like this, a bent into shape of two places bending on track beam backplate is achieved; Horizontal reset on last upper module, unloads U-shaped pressing plate, will survive workpiece 2
,take off from lower module.
