Description
Technical field
The utility model relates to a kind of metal forming machinery, specifically, relates to a kind of electro-hydraulic servo sealing workpiece dedicated numerical control bender that seals the workpiece bending automatically.
Background technology
The rectangle square tube of large-sized sealing can't obtain through cold drawing molding, generally will realize with bender processing.The sealing workpiece adopts bender processing, because the restriction of structure, bender can't directly process the rectangle square tube workpiece of sealing.Can not reach the slitless connection that seals workpiece according to conventional cooked mode, the workpiece after the bending has the slit that differs in size, and can only fold the workpiece of semi-enclosed shape of approximate drawing requirement, before being welded into the sealing workpiece, will carry out shaping.Shaping is exactly in the rigid sealing in the slit that stays on the workpiece after the bending before the weldering, welds after the shaping, accomplishes the workpiece of drawing requirement.This way can very easily be damaged surface of the work, and the result of shaping varies and cause the quality of workpiece processing uncontrollable.
Summary of the invention
The purpose of the utility model is the weak point that overcomes prior art, and a kind of electro-hydraulic servo sealing workpiece dedicated numerical control bender is provided.
The electro-hydraulic servo sealing workpiece dedicated numerical control bender of the utility model; Comprise fuselage part, be located at back Slipper, be fixed in the Slipper below patrix, be located at hydraulic system, the electro-hydraulic servo digital control system of the workbench part of underbelly, the counterdie that is fixed in the workbench top, charged hydraulic servo and be located at the back stock stop of underbelly; The C template is equipped with in said fuselage both sides; The grating chi is housed on the C template; Said Slipper comprises slide block and is fixed in the left and right sides oil cylinder of fuselage both sides, and the slide block left side is provided with the hollow out formula and connects template and connect template with the movable type that can pass in and out, and the fuselage left side is provided with into hull and pulp removing machine structure.
Preferably, said patrix is reinforced patrix, is used to compensate the deflection deformation that connects the patrix of template generation because of hollow out.
The electro-hydraulic servo sealing workpiece dedicated numerical control bender of the utility model is for realizing the slitless connection of workpiece; Adopt big stroke slider and hollow out formula anchor clamps and mould; Anchor clamps and mould produced and interfere the position to carry out hollow out when workpiece was docked; Simultaneously the profile and the condition of heat treatment of mould are carried out particular design, through intensity that improves mould and then intensity and the rigidity that improves complete machine.The ERROR CONTROL of final bending angle satisfies the requirement of processing sealing workpiece at 1 degree;
After the workpiece bending is accomplished,, can't take out, therefore design automatic demoulding and progressive die mechanism, adopt two cylinders to carry out translation and upset in equipment one side from processing stations because be close-shaped, and between move interlocking, the workpiece that assurance processes takes out smoothly.
But the length and width height of processing work dimensional requirement: 2mm below thick is at the sealing rectangle square tube of 1000mmX (100mm-300mm) X (200mm-460mm) scope (or in this scope other close-shaped), strength of materials δ b≤600Mpa.The workpiece of other sizes can be realized through same or analogous principle.
Specifeca tion speeification:
Nominal pressure 1000KN bending length 2500mm (sealing workpiece 1000mm)
A precision ± 0.03 mm repetitive positioning accuracy, 0.01 mm is anticipated in backstop
Back backgauge R axle positioning accuracy ± 0.03 mm repetitive positioning accuracy, 0.02 mm
Slide block positioning accuracy ± 0.01 mm repetitive positioning accuracy ± 0.01 mm.
The electro-hydraulic servo of the utility model sealing workpiece dedicated numerical control bender has following technique effect: the mode through Bending Processing realizes directly processing the sealing workpiece of the rectangle square tube and other the shape of sealing; Reaching the slitless connection of workpiece, and the finished product after the processing can conveniently take out from the bending position.
