For realizing above-mentioned purpose; The technical scheme that the utility model is taked is: the apparatus for bending of a kind of sheet metal that is provided; Comprise the support that is fixed in ground, described support comprises the vertical support bar that is fixed in ground with the girder two ends of the girder that is parallel to ground, and described girder is hung with jack; The upper end of the crossbeam that can slide along support bar that the base of jack is fixed in that support has, the both sides of jack are respectively arranged with the extension spring that connects girder and crossbeam; The lower end of crossbeam is provided with the punching press connecting rod, and the punching press connecting rod is connected with the patrix of stamping die, and the two ends of stamping die counterdie are connected with the support bar of both sides respectively.
Described support bar is symmetrically arranged with the connecting hole of the counterdie of stamping die, the counterdie of stamping die through connecting hole and support bar for removably connecting.
The patrix of described stamping die is provided with plush copper, and the counterdie of stamping die is provided with the groove adaptive with it.
The patrix of described stamping die and punching press connecting rod are for removably connecting.
Described crossbeam and punching press connecting rod are for removably connecting.
Adopt the technical scheme of the utility model, sheet metal places on the counterdie of stamping die, pushes jack; Move down drive punching press connecting rod with the affixed crossbeam of jack base along support bar and press down, the patrix of connected stamping die moves to stamping die counterdie direction thereupon, and the plush copper extrusion metal thin plate that patrix is provided with moves to the groove of counterdie; Accomplish sheet metal bending operation; The shape of mould is fixed, and the profile of the bending of sheet metal conforms to mould, has guaranteed its machining accuracy; After the plush copper bottom and the counterdie bottom portion of groove of patrix coincide; The bending operation is accomplished; The compression relief cock of twisting jack, whole base can be got back to original position under the effect of the pulling force of extension spring, and the hydraulic jack applied pressure is uniform; The size uniformity of sheet metal bending has overcome the defective that the manual machining accuracy of prior art is difficult to guarantee; This processing mode need not to drop into main equipment, has alleviated the input cost of manufacturer; The patrix of stamping die and punching press connecting rod are for removably connecting, and crossbeam and punching press connecting rod are for removably connecting, and be different according to machining shape, changes difform mould, makes things convenient for the processing of difformity bending workpieces.
Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.
