Abstract
The invention provides a pressing part structure for a bent plate of a crane, which can prevent a lower die from separating and reciprocating due to unbalanced stress in a pressing process, thereby ensuring the bearing strength of the die and prolonging the service life of the die. The structure comprises a lower die body and a lower die holder welding part structure, wherein the lower die holder welding part structure comprises a base plate, a base upper plate and a base. The structure is characterized in that: the lower die body is a whole embedded lump; the base plate and the base are mounted and fixed by virtue of bolts and pins; and the base and the base upper plate are connected by virtue of welding.
Description
Technical field
the present invention relates to the die apparatus of crane tailstock part deformation, are specially a kind of crane bent plate and press shape part structure.
Background technology
crane tailstock part is generally bent plate spare, and making bent plate spare need be with the sheet material of definite shape through a kind of distortion die apparatus press forming.The die apparatus of the crane tailstock part deformation of present domestic employing; Its structure: asymmetric, the spliced counterdie split of workpiece, die shoe weldment structural design adopt the conventional design mode of welding assembly order from top to bottom; Be the welding of bedplate, base and then be connected through screw with the base upper plate; This structure exists discontinuity equalization to be easy to generate counterdie split play, and a little less than the mould bearing strength, influences the defective of die life.
Summary of the invention
There is above-mentioned defective in
to the die apparatus of existing crane tailstock part deformation; The invention provides a kind of crane bent plate and press shape part structure; Can prevent to press in the shape process and produce counterdie split play because of discontinuity equalization; Guarantee the mould bearing strength, prolong the service life of mould.
its technical scheme is such: it comprises lower mold body and die shoe weldment structure, and described die shoe weldment structure comprises bedplate, base upper plate, and base is characterized in that: described lower mold body adopts integral body to insert; Described bedplate and base are installed and fixed by screw and pin, and base and base upper plate are through being welded to connect.
It is further characterized in that
: described lower mold body and die shoe weldment structure are through eight positioning key location.
the present invention adopt after the said structure, and lower mold body adopts whole inserting to replace original counterdie split, prevented to produce counterdie split play because of discontinuity equalization in the pressure shape process; Die shoe weldment structure adopts bedplate and base to be installed and fixed by screw and pin, and base and base upper plate have changed original welding sequence through being welded to connect, and have increased bulk strength; Lower mold body and die shoe adopt the positioning key location, have promptly guaranteed the mould bearing strength, have prolonged the service life of mould, are convenient for changing again.
Description of drawings
Fig. 1 is a partial sectional view of the present invention.
The specific embodiment
Fig. 1 is seen in
; The present invention includes and comprise lower mold body 6 and die shoe weldment structure, die shoe weldment structure comprises bedplate 3, base upper plate 2, base 1; Bedplate 3 is installed and fixed by screw 4 and pin 5 with base 1; Base 1 and base upper plate 2 are through being welded to connect, and lower mold body 6 adopts integral body to insert, and lower mold body 6 is located (not expressing other four positioning keys among the figure) with die shoe weldment structure through eight positioning keys 7.
