Description
Technical field
The present invention relates to carrier part forming mode structure, be specially the perpendicular coaming plate pressure-shaped mould structure of a kind of carrying vehicle frame.
Background technology
The characteristics of the perpendicular coaming plate part of carrying vehicle frame are: the big and thin thickness of appearance and size; Adopt traditional perpendicular coaming plate part of bending technique method preparation carrying vehicle frame at present; Its operation is many, workpiece is prone to resilience in the BENDING PROCESS, and production efficiency is low, and presses the dimensional requirement of shape to be difficult to guarantee.
Summary of the invention
To the problems referred to above, the invention provides the perpendicular coaming plate pressure-shaped mould structure of a kind of carrying vehicle frame, can when guaranteeing to press the shape dimensional requirement, overcome the workpiece resilience, realize the single use deflectable moulding.
Its technical scheme is such:
It comprises die, punch, and said die divides left die, right die to be fixedly connected with die shoe respectively, and the working face of said left die and said right die is a cambered surface; It is characterized in that: between said left die and the said right die top board is set; Said cover top surface is a cambered surface, with the complete cambered surface of the identical formation one side of the working face of said left die and said right die, push rod is set in the middle of the bottom of said top board; Said push rod upper surface contacts with said top board lower surface; Said push rod lower surface connects hydraulic cylinder, setting-in rotating shaft respectively on said left die and said right die, and said rotating shaft outer surface has the V-type notch; The inner bearing pin of installing of said rotating shaft; The outside of said rotating shaft is at the inner bearing pin of installing of said die, and the bearing pin center line of bearing pin center line that said rotating shaft is inner and said die inside is on same horizontal line, and the inner bearing pin of said rotating shaft is connected through extension spring with the inner bearing pin of said die.
It is further characterized in that: on said die shoe top board, open clear opening, said clear opening has three at least; Said top board bottom connects lead, and said lead passes said clear opening; Said lead quantity is at least two.
After the present invention adopted above-mentioned improvement structure, when workpiece was carried out brake forming, lathe work promoted push rod jack-up top board; Maintain an equal level when top board rises to the die top, this moment, the rotating shaft that is embedded on the left die was rotated counterclockwise owing to the effect of extension spring; The rotating shaft that is embedded on the right die turns clockwise, the descending contact top board of while punch, and punch is advanced into die an actor's rendering of an operatic tune under the top board clamping work pieces; The complete cambered surface that top board, left die, right die constitute and the working face one of punch react on workpiece, and when punch touches rotating shaft, along with pressure increases; The rotating shaft that is embedded on the left die turns clockwise; The rotating shaft that is embedded on the right die is rotated counterclockwise, and punch is pushed down the V-type notch place that workpiece is clamped on rotating shaft, to pressing shape to accomplish.Therefore in whole pressure shape process, rotating shaft and top board are all participated in forming process, and they give workpiece certain pressure shape power with punch, make the workpiece spring-go little, one-shot forming, and press the size of shape can satisfy technological requirement.
Description of drawings
Fig. 1 is the partial sectional view of front view of the present invention;
Fig. 2 is the A place enlarged drawing of Fig. 1.
The specific embodiment
See Fig. 1, the present invention includes die 1, punch 8,1 fen left die of die, right die; Be fixedly connected with die shoe 11 respectively, the working face of die 1 left die and right die is a cambered surface, between the middle part left side die of die 1 and the right die top board 3 is set; Top board 3 upper surfaces are cambered surface, and coincideing with the working face of the die 1 of left die and right die constitutes the complete cambered surface of one side, and push rod 2 is set in the middle of the bottom of top board 3; Push rod 2 upper surfaces contact with top board 3 lower surfaces, and push rod 2 lower surfaces connect hydraulic cylinder (hydraulic cylinder is expressed in the drawings), nested dress rotating shaft 5 respectively on die 1 left die and right die; Corresponding die 1, punch 8 matched moulds moulding place, rotating shaft 5 outer surfaces have V-type notch 12 (see figure 2)s, the rotating shaft 5 inner bearing pin 6-1 that install; The outside of rotating shaft 5 is at the die 1 inner bearing pin 6-2 that installs, and the bearing pin 6-2 center line of the bearing pin 6-1 center line of rotating shaft 5 inside and die 1 inside is on same horizontal line, and rotating shaft 5 inner bearing pin 6-1 are connected through extension spring 7 with die 1 inner bearing pin 6-2; On die shoe top board 10, open clear opening 13, clear opening 14; Clear opening 13 has two at least, and top board 3 bottoms connect lead 9, and lead 9 quantity are at least two.Die 1 uses the Cr12 material with punch 6, and punch 8 adopts the line cutting processing to accomplish.
Below in conjunction with Fig. 1 the course of work of the present invention is described:
When workpiece was carried out brake forming, lathe work hydraulic cylinder promoted push rod 2, and push rod 2 is up and pass the clear opening 14 in the middle of the die shoe top board 10; Jack-up top board 3 continues up, and the effect of the lead 9 of top board 3 bottoms can make top board 3 in uphill process, guarantee to move non-migration in same vertical direction, maintains an equal level when top board 3 rises to die 1 top; Extension spring this moment 7 effects cause the rotating shaft that is embedded on the left die to be rotated counterclockwise, and the rotating shaft that is embedded on the right die turns clockwise; While punch 8 descending contact top boards 3; Punch 8 is advanced into die 1 an actor's rendering of an operatic tune under top board 3 clamping work pieces, and when punch 8 touches rotating shaft 5, along with pressure increases; The rotating shaft that is embedded on the left die on die 1 left side turns clockwise; The rotating shaft that is embedded on the right die on die 1 the right is rotated counterclockwise, and punch 8 is pushed down workpiece and chucking, and workpiece is in the notch 12 places moulding of rotating shaft 5.Therefore in whole pressure shape process, rotating shaft 5 is all participated in forming process with top board 3, and they give workpiece certain pressure shape power with punch 8, make the workpiece spring-go little, one-shot forming, and press the size of shape can satisfy technological requirement.After workpiece presses shape to finish, punch 8 up returning, the pressure on the workpiece reduces until being 0, and rotating shaft 5 resets under the pulling force of extension spring 7 again, when extension spring 7 resets, can also play the material effect of taking off to workpiece.
