Abstract
The utility model provides a deep-U-shaped workpiece forming mold, which relates to forging and pressing machinery. The deep-U-shaped workpiece forming mold comprises an upper die and a lower die, particularly, the lower die is formed by a pair of fishhook-shaped movable dies, the two fishhook-shaped movable dies are oppositely placed in a groove of a lower die seat, and corners at both sides of the bottom of the groove of the lower die seat are designed into large circular-arc-shaped corners and are anastomotic with corners formed at the back parts of the two fishhook-shaped movable dies. The deep-U-shaped workpiece forming mold has the advantages that the structure is compact, the workpiece forming is standard, and the deep-U-shaped workpiece forming mold is particularly suitable for being used for processing and forming deep-U-shaped workpieces.
Description
The ㈠ technical field: the utility model relates to the metal forming machinery in the mechanical engineering, especially a kind of dark U-shaped Workpiece shaping mould.
The ㈡ background technology: at present dark U-shaped Workpiece shaping mode mainly contains following two kinds, and the one, with return flanging die molding mode at twice; The 2nd, with common flute profile counterdie structure, mainly be size and the bending degree of depth one-shot forming mode that changes upper and lower die clearance; Though above-mentioned dual mode all can reach certain molding effect, the former mainly is suitable for the big U-shaped Workpiece shaping of opening; The latter is when upper and lower die clearance is excessive, and the workpiece angle is greater than 90 ° after the bending, and when the gap was too small, the workpiece clamp mould of staying can't discharging, and the moulding angle can not meet the demands.
The ㈢ summary of the invention: the purpose of this utility model will solve existing dark U-shaped Workpiece shaping mould exactly, and Workpiece shaping is nonstandard, and the problem of discharging difficulty provides a kind of new moldeed depth U-shaped Workpiece shaping mould.
Concrete scheme of the present utility model is: a kind of dark U-shaped Workpiece shaping mould, include upper die and lower die, it is characterized in that: described counterdie is made up of the hook-shaped movable mold of a pair of fish, two hook-shaped movable mold of fish are staggered relatively in the groove of a die shoe, the both sides corner design of die shoe bottom portion of groove is the circular arc corner, matches with the back corner of two hook-shaped movable mold of fish.
Inboard, two fish hook-shaped movable mold upper ends described in the utility model is an arc chord angle, the outside is a ledge structure, and suitable for reading two inboard designs at the die shoe groove have ledge structure, step surface on the die shoe is higher than the step surface on the hook-shaped movable mold of fish, and adopts screw that at least two key pieces are installed on the die shoe step surface.
For solving dustproof problem, the utility model is equipped with dust excluding plate in two hook-shaped movable mold of fish and die shoe upper end joint.
Rotate when guaranteeing that two hook-shaped die workers of fish do flexibly, the utility model respectively is equipped with some lubricator cups in both sides before and after die shoe, and is communicated with the contact-making surface of two hook-shaped movable mold of fish and die shoe by oil circuit.
Be convenient processing, counterdie described in the utility model and die shoe length is to being divided into plurality of sections, and connects dress by a flute profile counterdie positioning seat and be one.
Operation principle of the present utility model is: during the firm moulding of workpiece is free bending, workpiece touches counterdie upper end roundlet nock, when patrix continues to press down, patrix contacts with two hook-shaped movable mold of fish and two hook-shaped movable mold of fish is rotated with the orthodrome corner, so workpiece is pressed to from both sides in two the hook-shaped movable mold of fish upper ends, thereby the moulding angle is less than 90 ° of U-shaped workpiece, after patrix withdraws from, the workpiece resilience becomes standard U-shaped workpiece, stroke by control bender or slider of hydraulic press, make the workpiece bent into shape at last, reach dark U-shaped Workpiece shaping purpose.
The utility model structure has possessed perfect craft performance and economy, compact conformation, and the Workpiece shaping standard, discharging is convenient.
The ㈣ description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is an A-A zoomed-in view among Fig. 1.
Among the figure: 1-die shank, 2-patrix, 3-screw, 4-lubricator cup, 5-die shoe, 6-counterdie positioning seat, 7-lock-screw, 8-workpiece, 9-dust excluding plate, 10-screw, 11-key piece, 12-screw, 13, the 14-ledge structure, the hook-shaped movable mold of 15-fish, 16-groove.
The ㈤ specific embodiment:
Referring to Fig. 1, Fig. 2, the utility model includes patrix 2 and counterdie, patrix 2 adopts a plurality of screws 3 to be connected with die shank 1, particularly: described counterdie is made up of the hook-shaped movable mold 15 of a pair of fish, two hook-shaped movable mold 15 of fish are staggered relatively in the groove 16 of a die shoe 5, the both sides corner design of die shoe groove 16 bottoms is the circular arc corner, matches with the back corner of two hook-shaped movable mold 15 of fish.Inboard, the hook-shaped movable mold of described two fishes 15 upper ends is an arc chord angle, the outside is a ledge structure 13, and suitable for reading two inboard designs at die shoe groove 16 have ledge structure 14, step surface on the die shoe 5 is higher than the step surface on the hook-shaped movable mold 15 of fish, and adopts screw 12 that 12 concrete numbers of key piece 11(are installed on the die shoe step surface and determine according to counterdie length).
Adopt screw 10 that dust excluding plate 9 is installed in two hook-shaped movable mold of fish and die shoe upper end joint in the present embodiment.And in both sides, die shoe 5 front and back 6 lubricator cups 4 are housed respectively, and are communicated with the contact-making surface of two hook-shaped movable mold of fish and die shoe by oil circuit.
Make for convenience processing, counterdie described in the present embodiment and die shoe length is to being divided into six sections, and connects dress by a flute profile counterdie positioning seat and a plurality of lock-screw 7 and be one.Promptly constitute preferred structure of the present utility model.
