Abstract
The invention provides a loader coaming profiling mold which has the advantages that a coaming is equally stressed in the shaping process, wrinkles and springback phenomena are eliminated and the profiling size meets design requirements. The profiling mold comprises a concave mold and a convex mold, wherein the convex mold comprises a shaping convex mold. The profiling mold is characterized in that the convex mold comprises a shaping guide convex mold; the convex mold comprises a convex mold fixing plate; the convex mold fixing plate is connected with a convex mold seat through a guide column and a spring; and the side edge of the shaping guide convex mold is designed to be matched with the shaping convex mold according to springback angles.
Description
Technical field
The present invention relates to the tooling structre of loading machine fuselage part, be specially loading machine coaming plate pressure-shaped mould.
Background technology
Loading machine coaming plate belongs to sheet parts, and workpiece is large and dark, uses traditional handicraft to add man-hour, easy resilience in coaming plate forming process, wrinkling, causes size not meet designing requirement, causes production efficiency low.
Summary of the invention
For the problems referred to above, the invention provides a kind of loading machine coaming plate pressure-shaped mould, can make coaming plate in forming process, stress equalization, eliminate wrinkling, rebound phenomenon, guarantee the designing requirement of swaging size conforms.
The technical solution adopted in the present invention is: it comprises die body and body of punch, described body of punch comprises forming terrace die, it is characterized in that: described body of punch comprises the guiding punch that is shaped, described body of punch comprises punch retainer, described punch retainer is connected with convex mould base with spring by guide pillar, and described shaping guiding punch side is designed to conform to forming terrace die by spring back angle.
It is further characterized in that: described forming terrace die is connected with described punch retainer by screw; Described shaping guiding punch is connected with described body of punch by screw; Described spring fitting is on described guide pillar.
After adopting design of the present invention, in the descending process of body of punch, described forming terrace die contact workpiece, spring-compressed, workpiece is descending, and described shaping guiding punch vertical direction plays blank holder effect, gives workpiece lateral pressure, effectively controls workpiece resilience.After component shaping terminates, body of punch is up, and under counter spring force effect, punch retainer homing, plays discharging effect.In component shaping process, the bounce of spring acts on body of punch, make die body steady, contact workpiece lentamente, slow down component shaping speed, in component shaping process, its periphery remains continuous uniform thrust, effectively prevents wrinkling, improve workpiece presentation quality, make it meet designing requirement.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, the present invention includes die body 8 and body of punch 2, body of punch 2 comprises guide pillar 3, spring 4, punch retainer 5, convex mould base 1, forming terrace die 6 and the guiding punch 7 that is shaped, punch retainer 5 is connected with convex mould base 1 with spring 4 by guide pillar 3, forming terrace die 6 is connected with body of punch 2 by screw 9, and the guiding that is shaped punch 7 is connected with punch retainer 5 by screw 10.
In the descending process of body of punch 2, forming terrace die 6 contacts workpiece, and spring 4 compresses, and workpiece is descending, and the guiding that is shaped punch 7 vertical direction plays blank holder effect, gives workpiece lateral pressure, effectively controls workpiece resilience.After component shaping terminates, body of punch 2 is up, and under the effect of spring 4 counter-force, punch retainer 5 homing, plays discharging effect.In component shaping process, the bounce of spring 4 acts on body of punch 2, make die body 8 steady, contact workpiece lentamente, slow down component shaping speed, in component shaping process, its periphery remains continuous uniform thrust, effectively prevents wrinkling, improve workpiece presentation quality, make it meet designing requirement.
