Abstract
The utility model discloses a vehicle longeron forming die, including upper die base (1) and die holder (2) die holder (2) on install die (3) upper die base (1) on install terrace die (4) terrace die (4) on be equipped with pilot pin (5) die (3) on be equipped with and lead positive hole (6) with pilot pin (5) complex die holder (2) and die (3) on all be equipped with the locating hole the locating hole in be equipped with locating pin (7) die (3) in be equipped with material returned board (8) and ejector beam (9) that are used for unloading, die holder (2) and die (3) between through the bolt fastening the opening of die (3) be two segmentation U type structures, this mould is because the opening part adopts two segmentation U type structures, improve equipment availability factor and life, realize longeron and lining roof beam while integrated into one piece.
Description
Technical field
The utility model belongs to mould, is specifically related to a kind of mould of vehicle rail.
Background technology
The mode that current longitudinal beam of automobile frame assembly structure generally adopts vertical lining beam to close beam increases the intensity of longeron assembly, and namely in order to improve the bearing capacity of automobile longitudinal girder, the lining beam increasing 1-4mm less of longeron thickness at side rail inner improves longeron intensity and bearing capacity.At present both at home and abroad manufacturing process is generally adopt longeron and the individually blanking of liner beam, punching, cutting deformation district, shaping, then by the plug welding of liner beam press-in longeron, thoroughly bores the scheme in lining beam hole finally by longeron.This scheme is a kind of scheme of maturation, therefore most widely used general.But the shortcoming of this scheme is: operation is many, and cost is high, and there is gap between vertical, lining beam, not only cause large beam strength to reduce, also for postorder production such as spot welding, open-work, ball blast, application etc. bring inconvenience.Take the one-body molded gapless production technology of longeron, liner beam, not only can eliminate between vertical, lining beam and there is gap and can also strengthen bearing capacity.Serve as a contrast beam hole was that the operation of boring changes numerical control punching into simultaneously originally, greatly improved production efficiency and product quality.Processing the mould that existing longeron uses is all traditional structure, and service life is short, and can only single processing longeron and lining beam.
Utility model content
In order to solve deficiency of the prior art, provide one can by longeron and lining beam time processing shaping, and long service life, the mould of stabilized structure.
The technical scheme that the utility model adopts is:
A kind of vehicle rail mould, include upper bolster and die shoe, described die shoe is provided with die, described upper bolster is provided with punch, described punch is provided with pilot pin, described die is provided with the correcting hole coordinated with pilot pin, described die shoe and die are equipped with locating hole, alignment pin is provided with in described locating hole, the stripper for discharging and ejector beam is provided with in described die, be bolted between described die shoe and described die, be the U-shaped structure of two-part at the opening of described die.
Described die shoe sidewall is provided with some screw holes, described die sidewall is provided with some fixing holes mated with screw hole.
The U-shaped structure of two-part is funnel-form and with radian.
Described two-part is U-shaped comprises pre-curved segment and bending segment.
Described die shoe and upper bolster are respectively equipped with and hang charge bar.
The beneficial effects of the utility model are:
This mould adopts two-part U-shaped structure due to opening part, and longeron and lining beam enter the die stage and first carry out pre-bending, thus reach the object of school type stage control resilience; Because longeron and lining beam first carry out pre-bending, and unconventional right angle is shaping, reduces operating pressure, thus improves equipment use efficiency and service life; Due to the shaping reduction operating pressure in unconventional right angle, also reduce tablet to the wearing and tearing at die mouth insert R angle simultaneously, improve die life, realize longeron and serve as a contrast beam simultaneously one-body molded; Due to longeron and lining beam simultaneously one-body molded, so the active force between part and mould is larger, link between die shoe and die with bolt, when preventing molding, die chunk is taken up by workpiece.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Fig. 2 is traditional structure sectional view.
Detailed description of the invention
The sectional view of the utility model mould as shown in Figure 1, include die shoe 2 and upper bolster 1, die shoe 2 is provided with die 3, upper bolster 1 is provided with punch 4, punch 4 is provided with pilot pin 5, die 3 is provided with the correcting hole 6 coordinated with pilot pin 5, die shoe 2 and die 3 are equipped with locating hole, alignment pin 7 is provided with in locating hole, the stripper 8 for discharging and ejector beam 9 is provided with in die 3, die shoe 2 and upper bolster 1 are respectively equipped with and hang charge bar 14, be conveniently arranged on die shoe 2 and upper bolster 1 be respectively equipped with and hang charge bar 14.The opening part of die 3 is the U-shaped structure of two-part, mould traditional as shown in Figure 2 adopts the U-shaped structure in right angle, owing to longeron and lining beam being processed respectively and then are grouped together in tradition processing, and the utility model is in order to realize longeron and the machine-shaping of lining beam one, the U-shaped structure of two-part is adopted at opening part, the U-shaped structure of this two-part includes pre-curved segment 12 and bending segment 13, be funnel-form with the U-shaped structure of opening part two-part of die traditional in Fig. 2 this utility model mutually and with radian, longeron and lining beam are introduced into pre-curved segment when entering die 3 and carry out pre-bending, thus reach the object of school type stage control resilience.Because longeron and lining beam first carry out pre-bending, and unconventional right angle is shaping, reduces operating pressure, thus improves equipment use efficiency and service life, thus realizes longeron and the integrated object of lining beam.And due to the shaping reduction operating pressure in unconventional right angle, also subtract longeron simultaneously and serve as a contrast beam to the wearing and tearing at die 3 mouthfuls of insert R angles, improve die life.Die shoe 2 sidewall is also provided with some screw holes 10, die 3 sidewall is also provided with some fixing holes 11 mated with screw hole 10, by bolt, die 3 is fixed on die shoe 2, due to one-body molded while of longeron and lining beam, so the active force between part and mould is larger, link with bolt between die shoe and die, when preventing molding, die chunk is taken up by workpiece.
