Description

Metal sheet stamping, bender

The utility model relates to a kind of punching press of metal blank, the device of brake forming.

Chinese patent has provided a kind of " sheet metal bender " for No. 92238094.5, and this machine is at the hinged bend bar in template side, and during bent plate, bend bar is that rotate and the brake forming of pushing sheet material at the center with the hinge.In the bending machining process, bend bar does not have relative sliding friction with sheet material, can avoid scratching in process plate surface.To the exigent casing deckle board of presentation quality, moulding perfection and plate surface have no damage with this machined refrigerator doors etc.

But, along with the variation of the market demand, some newly-designed product door-plate or casings not only require the perfection of material bending moulding, also require to stamp out on the plate face concavo-convex shape simultaneously, above-mentioned sheet metal bending make-up machine is difficult to finish punching press and crooked two procedures on a working face.

The purpose of the utility model is to provide a kind of metal sheet stamping, the bender that can successively finish punching press, bending on a working face.

Described metal sheet stamping, bender, there is main drive to be fixed on the back timber and can promotes the forcing press that walking beam moves up and down along guide pillar, the sheet bending mould is housed in the forcing press, walking beam has a floor stringer, assistant drive device can drive walking beam and move relative to floor stringer, the cope match-plate pattern of sheet bending mould is contained in the floor stringer bottom surface, lower bolster is contained on the base, and the stamping die of forming by the former and the formpiston of correspondence respectively on the bolster, one end and the walking beam of push rod are hinged, and the other end and bend bar are hinged.

When using described make-up machine to process plate, processed sheet material places on the lower bolster, and main drive promotes walking beam and moves downward, and floor stringer is synchronized with the movement with walking beam.When floor stringer moves downward the upper and lower template contact of mould is compressed, finish after the punching press, main drive stops action, the assistant drive device action, drive walking beam and move to the floor stringer direction, simultaneously, the push rod that is hinged on the walking beam promotes bend bar, and be that rotate at the center with the hinge of this module and cope match-plate pattern, finish the action of bent plate.This machine can successively be finished punch forming and brake forming on a working face.The precision height of moulding, efficient is high and can not damage the surface of processed sheet material.

Fig. 1 adopts the master of the described make-up machine of fluid pressure drive device to look schematic diagram

Fig. 2 adopts the master of the described make-up machine of fluid pressure drive device to look schematic diagram

Fig. 3 adopts the master of the described make-up machine of mechanical actuation device to look schematic diagram

Embodiment is just like Fig. 1

The hydraulic-driven forcing press that has base 1 guide pillar, 2 walking beam 10 back timbers, 13 master cylinders 12 and hydraulic system to constitute is equipped with the sheet bending mould in the forcing press, be prior art.Walking beam 10 has floor stringer 8, and main drive 12 is master cylinders 12, and its piston rod links to each other with walking beam 10, and assistant drive device 11 is an auxiliary oil cylinder, and auxiliary oil cylinder 11 is fixed on the walking beam 10, and its piston rod links to each other with floor stringer 8.When auxiliary oil cylinder 11 is failure to actuate, main drive 12 be master cylinder 12 when promoting walking beams 10 and move floor stringer 8 also be synchronized with the movement.The epicoele pressure release of auxiliary oil cylinder 11, the piston rod of master cylinder 12 continue to move downward can make walking beam 10 move to floor stringer 8 directions.The cope match-plate pattern 7 of bending mould is contained in below the floor stringer 8, and lower bolster 3 is contained on the base 1, the stamping die of being made up of the die 4 and the formpiston 5 of correspondence respectively on the bolster 3,7.One side and cope match-plate pattern 7 sides of bend bar 6 are hinged, and opposite side and push rod 9 are hinged, and the upper end of push rod 9 and walking beam 10 are hinged.When walking beam 10 when floor stringer 8 directions move, it is that rotate at the center with the hinge of itself and cope match-plate pattern 7 that push rod 9 can promote bend bar 6, finishes the action of crooked sheet material.

Embodiment two is as Fig. 2

Assistant drive device 11 is that to be enclosed within main drive 12 be on the piston rod in the master cylinder 12 to auxiliary oil cylinder 11, and at the piston back side and auxiliary oil cylinder 11 tops formation auxiliary oil cylinder epicoele 11A, auxiliary oil cylinder 11 bottoms link to each other with walking beam 10, the piston rod bottom links to each other with floor stringer, and the composite oil cylinder of formation is main drive and assistant drive device.When master cylinder 12 epicoeles are exerted pressure, its piston rod moves downward also is being with auxiliary oil cylinder 11 mass motions, promptly realizes being synchronized with the movement of walking beam 10 and floor stringer 8.Exert pressure in the epicoele 11A of auxiliary oil cylinder, can make walking beam 10 relative floor stringer 8 motions.All the other are identical with embodiment one.

Embodiment three is as Fig. 3

Main drive 12 is a driving screw 12, and its top fast pulley 15, assistant drive device 11 are sub-screw 11, and its top fast pulley 14 has screw shell 16 to be enclosed within outside the driving screw 12 within the sub-screw 11, and links to each other with major and minor screw rod 12,11 screw threads respectively.The lower end of screw shell 16 links to each other with floor stringer 8, and the lower end of sub-screw 11 links to each other with walking beam 10.Belt pulley 15 drive driving screws 12 rotations can drive the screw shell 16 that links to each other with its screw thread downwards promotion floor stringers 8, drive sub-screw 11 simultaneously and move downward, for being synchronized with the movement together with walking beam 10.Belt pulley 14 drives sub-screw 11 rotations, and sub-screw 11 moves relative to screw shell 16, and promptly walking beam 10 moves relative to floor stringer 8.All the other are identical with embodiment one.
