Abstract
The utility model relates to a special local bending die for manufacturing automobile rear axle assembly front crossbeams. The automobile rear axle assembly front crossbeams which are bent and manufactured through the die have good performance and low cost. The special local bending die comprises an upper die structure and a lower die structure. The special local bending die is characterized in that a stationary barrier is installed on the lower die, a flap supporting frame is installed on the stationary barrier through a rotation shaft, a hydraulic core-pulling device is installed on the flap supporting frame, a core-pulling bar is connected with a piston rod of a hydraulic cylinder through a universal joint, a top board is arranged on the lower portion of the lower die, the top board is sleeved on a guide pad, the guide pad is installed on a lower template, the lower portion of the top board is connected with a push rod, and the push rod is threaded through the lower template.
Description
(1) technical field
The utility model relates to the mould correlation technique, belongs to the auto parts and components die for manufacturing in the mechanical processing industry, is specially vehicle rear axle assembly breast beam and makes special-purpose local bending mould.
(2) background technology
The vehicle rear axle assembly development difficulty is very big, the front beam tubular member in the assembly particularly, and shape is peculiar, and the position, hole is many, complex procedures, the shaping difficulty is big, and is with high content of technology, and domestic still do not have a successfully precedent of exploitation.Domestic manufacturer all is from external import usually, makes the manufacturing cost of automobile improve, and then adds large user's financial burden.
(3) summary of the invention
At the problems referred to above, the utility model provides vehicle rear axle assembly breast beam to make special-purpose local bending mould, by the bending machining of this mould to vehicle rear axle assembly breast beam, make the performance of workpiece good, service life is longer, and cost is low, has quickened the production domesticization of automobile.
Its technical scheme is such, it comprises mode structure, following mode structure, it is characterized in that: fixed support is installed on counterdie, and the turnover panel support is installed on described fixed support by rotating shaft, and the hydraulic pressure core-pulling device is installed on described turnover panel support, the rod of loosing core connects the piston rod of hydraulic cylinder by universal joint, the bottom of described counterdie is provided with top board, and described top board is placed in guide pad, and described guide pad is loaded on described lower bolster, the bottom of described top board connects push rod, and described push rod passes described lower bolster.
It is further characterized in that: the described two ends of baffle plate down are respectively arranged with down block, and the following block at described two ends is respectively the overturning pivot of described turnover panel support.
Adopt the vehicle rear axle assembly breast beam of above-mentioned Mould Machining, performance is good, and service life is longer, and cost is low, has realized the production domesticization of vehicle rear axle assembly breast beam, thereby has reduced user cost significantly.

Fig. 2 is a front view of the present utility model;
Fig. 3 is a vertical view of the present utility model.
(5) specific embodiment
See Fig. 1, Fig. 2, Fig. 3, the utility model comprises mode structure, following mode structure, fixed support 7 is installed on counterdie 8, and turnover panel support 6 is installed on fixed support 7 by rotating shaft 3, and the hydraulic pressure core-pulling device is installed on turnover panel support 6, the rod 5 of loosing core connects the piston rod of hydraulic cylinder 4 by universal joint, the bottom of counterdie 8 is provided with top board 11, and top board 11 is placed in guide pad 10, and guide pad 10 is loaded on lower bolster 13, the bottom of top board 11 connects push rod 9, and push rod 9 passes lower bolster 13.The two ends of lower bolster 13 are respectively arranged with down block 12, and the following block 12 at two ends is respectively the overturning pivot of turnover panel support 6, and 1 is that cope match-plate pattern, 2 is patrix.
Below in conjunction with accompanying drawing process of the present utility model is described, during the mould open mode, the preceding working procedure part is located by the profile of counterdie 8 earlier, hydraulic pressure core-pulling device in both sides is started working then, plug 5 inserts pipe two ends head, then patrix 2 is descending, promotes pipe fitting and counterdie 8, top board 11 toward pressing down.Turnover panel support 6 can 3 rotate in descending process around the shaft, during to bottom of stroke turnover panel support 9, turnover panel 14, plug 5 by original heeling condition along with pressing down of patrix 2 changes into level, thereby by patrix 2, turnover panel 14, plug 5 pipe is curved required angle.Plug 5 both can prevent the slight play of workpiece left and right directions in BENDING PROCESS, can prevent that again pipe fitting is not flat inwards when bending, and crooked position is full well-pressed.During die sinking, patrix 2 is up, counterdie 8 is being pushed away to up by top board 11 under the effect of lathe push rod 9, jack-up workpiece simultaneously, patrix 2 be during to the stroke end, and turnover panel support 6 and turnover panel 14 and hydraulic pressure core-pulling device recover heeling condition (plug 5 and hydraulic cylinder 4 position of loosing core is universal the connection, can be during die sinking) along with the up automatic adjustment angle of patrix 2, then start the hydraulic pressure core-pulling device, plug 5 is return, and takes out workpiece at last.
