Abstract
The invention provides a drawing die structure for a bridge cover plate of a crane, which can avoid edge corrugation of a workpiece in the whole forming process so as to ensure the appearance quality of a drawn workpiece. The drawing die structure comprises a concave die body and a convex die body, wherein the concave die body and the convex die body form a stepped forming cavity when combined; the concave die body and the convex die body are connected through guide pillars and guide sleeves; and the concave die body is arranged on a concave die pedestal, and the convex die body is arranged on a convex die pedestal. The drawing die structure is characterized in that: grooves are formed symmetrically on the left side and the right side in the concave die body; elastic parts are arranged in the grooves; each elastic part consists of a plug screw, a spring and a pin; and the pins can extend out of the grooves and contact the workpiece.
Description
Technical field
The present invention relates to the shaping moudle structure of crane body part, be specially a kind of crane pontic cover plate drawing die structure.
Background technology
The characteristics of crane pontic coverplate parts are: outward appearance is irregular, and its forming process is the multilayer drawing and moulding, and the workpiece drawing depth is big.The forming die structure that adopts at present creases easily at mould intermediate cavity edge in the Workpiece shaping process, causes that to pull out the workpiece presentation quality poor, influence product next procedure installation..
Summary of the invention
There is above-mentioned shortcoming to prior art, the invention provides a kind of crane pontic cover plate drawing die structure, can avoid workpiece edge wrinkling in whole forming process, guarantee to pull out the presentation quality of workpiece.
Its technical scheme is such; It comprises die body, body of punch, constitutes stepped molding cavity when said die body and said body of punch matched moulds, and said die body, said body of punch are connected with guide pin bushing through guide rod; Said die body is installed on the die pedestal; Said body of punch is installed on the punch pedestal, it is characterized in that: the left side and the right in said die body are symmetrical set slotted eye, in said slotted eye, elastic component are installed; Said elastic component is made up of plug screw, spring, bullet pin, and said bullet pin can stretch out said slotted eye contact workpiece.
It is further characterized in that: said slotted eye is set to stairstepping; Said elastic component is installed in the said stairstepping slotted eye, and said plug screw places said stairstepping slotted eye bottom and is fixed on the said die pedestal, and said bullet pin spiral-lock press-fits said spring in said stairstepping slotted eye middle part between said plug screw, the said bullet pin; At least two of said elastic component quantity.
The present invention adopts after the said structure, and workpiece is placed on the body of punch, and body of punch is up; Bullet pin elder generation contact workpiece before die body and body of punch matched moulds; Along with the up bullet pin of body of punch workpiece pressing edge, when die body and body of punch matched moulds, bullet pin compression spring is along slotted eye little the moving that slowly make progress; Spring reaction simultaneously is in the bullet pin; All the time give edge of work thrust at the forming process pin of being hit by a bullet, make workpiece in whole forming process, not crease easily at the edge, thereby guaranteed to pull out the presentation quality of workpiece.
Description of drawings
Fig. 1 is the partial sectional view of front view of the present invention.
The specific embodiment
See Fig. 1, the present invention includes die body 1, body of punch 2, constitute stepped molding cavity 3 when die body 1 and body of punch 2 matched moulds; Die body 1, body of punch 2 are connected (not providing guide rod and guide pin bushing among the figure) through guide rod with guide pin bushing, die body 1 is installed on die pedestal 4, and body of punch 2 is installed on punch pedestal 5; The left side in die body 1 and the right are symmetrical set slotted eye 6, and slotted eye 6 is set to stairstepping; Elastic component is installed in the stairstepping slotted eye 6; Elastic component is made up of plug screw 7-1, spring 7-2, bullet pin 7-3; Plug screw 7-1 places stairstepping slotted eye 6 bottoms and is fixed on the die pedestal 4; Bullet pin 7-3 spiral-lock is in stairstepping slotted eye 6 middle parts, and bullet pin 7-3 can stretch out slotted eye 6 contact workpieces, press-fits spring 7-2 between plug screw 7-1, the bullet pin 7-3; At least two of elastic component quantity, 8 is workpiece among the figure.
