Abstract
The utility model discloses an insert type bending die structure of a shock absorber lining, and relates to a molding die structure. The insert type bending die structure comprises a side molding female die, wherein a channel for the up-and-down movement of a male die (4) and a lifting block (8) is formed in the side molding female die; the part, corresponding to the position where the male die (4) and the lifting block (8) form a sheet (10), of the wall of the channel integrally extends outwards to form a filleted corner (12) matched with and attached to a finally formed outer filleted corner of the sheet (10). By combining a bending molding function and a shaping destressing function, the insert type bending die structure of the shock absorber lining effectively eliminates the bending resilient stress on the sheet, saves an extra shaping procedure and further ensures the accuracy of the final size of a product.
Description
Technical field
The utility model relates to a kind of forming die structure, relates in particular to a kind of damper liner formula bending mould structure of inserting.
Background technology
The damper liner is the strength member that is connected with car load with carriage, oil storage cylinder welding back, and the liner opening size requires strict, to guarantee that the subsequent handling welding smoothly accurately.Because of plate panel beating bending springback stress, final dimensional accuracy guarantees comparatively difficulty in the liner forming process.In the present mould molding design, all be by the bull nose brake forming of side molding concave die top, only has the brake forming function, and there is not integer destressing function, there is cavity between the bull nose of side molding concave die inwall and ejection block and plate final molding, can't eliminates the bending springback stress at plate fillet place, can not guarantee the two ends symmetry, also need to increase by one integer operation and clap liner side assurance opening size, increased extra cost.
The utility model content
Problem at above-mentioned prior art existence, the utility model provides a kind of damper liner formula bending mould structure of inserting, and in conjunction with brake forming and integer destressing function, effectively eliminates sheet metal bending resilience stress, save extra integer operation, more guaranteed product final size precision.
The technical solution of the utility model is: a kind of damper liner formula bending mould structure of inserting, comprise the side molding concave die, be provided with the passage that can supply punch and ejection block to move up and down in the side molding concave die, corresponding punch and ejection block are extended to outer lug the position one of plate final molding on described conduit wall, and form a filleted corner of fitting with the bull nose coupling of plate final molding.
The beneficial effects of the utility model are: the moulding principle that eliminates stress according to panel beating, on the basis of common side molding concave die with top bull nose brake forming, at side molding concave die inwall, corresponding punch and ejection block are provided with a filleted corner to the position of plate final molding on the conduit wall that can move up and down for punch and ejection block, this filleted corner is consistent with the bull nose of plate final molding, guarantee in moulding moment punch, plate and side molding concave die applying pressure-bearing, and the cooperation of the arc surface of ejection block bat repoussage type, to remove stress.This mould structure is integrated moulding, integer design to finish, and the work that moulding before just having guaranteed in one-shot forming, two operations of integer just can be finished has more guaranteed product final size precision.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1 punch retainer, 2 upper padding plates, 3 knockout rods, 4 punch, 5 location-plates, 6 die blocks, 7 die plate inserts, 8 ejection block, 9 lower bolsters, 10 plates, 11 brake forming bull noses, 12 filleted corners
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of damper liner formula bending mould structure of inserting, comprise the side molding concave die that is embedded in the die block 6, the side molding concave die comprises two die plate inserts 7, the side molding concave die is subjected to bigger brake forming frictional force and integer power, material selectivity can require high, it is consumable accessory, insert structure can be saved the mold materials expense, die plate insert 7 tops are provided with brake forming bull nose 11, the passage that Gong punch 4 between two die plate inserts 7 in the corresponding formation side molding concave die and ejection block 8 move up and down, the position one of 8 pairs of plate 10 final molding of corresponding punch 4 and ejection block is extended to outer lug on described conduit wall, and forms a filleted corner 12. of fitting with the bull nose coupling of plate 19 final molding
Before moulding; ejection block 8 is pushed up peak (this point is a little more than the liner locating surface); plate 10 is between ejection block 8 and punch 4; along with mainly by upper padding plate 2; punch retainer 1; punch 4; the punch mechanism that knockout rod 3 is formed presses down dnockout to plate 10; contract under ejection block 8 is slided in passage and play elasticity binder positioning action; plate 10 is by brake forming bull nose 11 brake formings on die plate insert 7 tops; reach plate 10 final molding positions until ejection block 8 and punch 4; 10 final molding moments of plate this moment; filleted corner 12 is fitted with plate 10 bull noses coupling on the conduit wall; punch 4; plate 10 and die plate insert 7 applying pressure-bearings are to remove stress; the final bottom surface of 8 pairs of plates of ejection block 10 moulding moment carries out the big pressure of final bottom surface arc surface and claps the destressing of repoussage type; effectively reduce the resilience stress of arc surface, guarantee bottom surface circular arc and opening size.
Claims (1)
1. damper liner formula bending mould structure of inserting, comprise the side molding concave die, be provided with the passage that can supply punch (4) and ejection block (8) to move up and down in the side molding concave die, it is characterized in that: corresponding punch (4) and ejection block (8) are extended to outer lug the position one of plate (10) final molding on described conduit wall, and form a filleted corner (12) of fitting with the bull nose coupling of plate (10) final molding.
