Description
Technical field
The utility model relates to the Technology of Plastic Processing field, the mould pressing equipment of particularly a kind of triangular-section part.
Background technology
Traditional spin forming method can be divided into two classes, i.e. conventional spinning (not flow turning) and shear spinning (flow turning).When carrying out conventional spinning or shear spinning, workpiece is installed on the machine tool chief axis, and rotates with the lathe main shaft, and spinning roller radially reaches axial feed motion along axis of workpiece, thereby is processed into the axial symmetry thin-walled hollow parts (single shaft spinning part) of different shape.
A kind of new spin forming method had appearred in recent years, when mould pressing, workpiece is installed on one can carry out at the same time or separately that vertical, horizontal moves and do in horizontal plane on the workbench of yaw motion along machine tool chief axis, and spinning roller is made revolution and spinning motion around workpiece, and can do feed motion along the revolution radial direction simultaneously, thereby process the non-axisymmetric parts (multiaxis spinning part) that is parallel to each other between the each several part axis or tilts.
But because in the above-mentioned spin forming method, the spinning roller device all is that the electric rotating machine of common stepper motor or servomotor and so on is realized by driving moving of ball screw assembly, along the horizontal feed motion of lathe, because the acceleration that electric rotating machine can produce is less relatively, thereby spinning roller all is static along the feed motion of workpiece radius direction, the commutation that is feed speed and speed is all relatively slow, so each cross section of the part that processes all is circular.And be the shaping of the sheet metal part of triangle or other shape for the cross section, if adopt spinning forming process, then need spinning roller to form bigger acceleration with respect to the rotary speed of workpiece self along the feed motion of workpiece radius direction, promptly along with the rotation of machine tool chief axis, spinning roller can commutate fast along the horizontal feed motion of lathe, adopt common electric rotating machine can't realize this requirement at all, so since spinning forming process comes out, also be not used in the shaping of on-circular cross-section sheet metal part.The general employing of this class part processes complex-shaped punch-die earlier, and the method for drawing, or employing then earlier is divided into several block-shaped simple parts with part and is formed separately, and then the processing of integrally welded method.This has not only increased operation, has prolonged the process-cycle, and to the situation of multi-varieties and small-batch, must make that production cost is too high, if adopt welding method, also can reduce the mechanical property of material, influences the normal use of part.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the mould pressing equipment of a kind of triangular-section part is provided, and this device structure is simple, the process-cycle is short, machining accuracy is high.
The utility model is achieved through the following technical solutions: the mould pressing equipment of a kind of triangular-section part, by main spindle box, lathe bed, vertically move platform, tail ejection device, servomotor feed arrangement, Hydraulic Station, linear electric motors feed arrangement, spinning roller device and console and form; Wherein main spindle box places the lathe bed left end, the tail ejection device place the lathe bed right-hand member and with the coaxial setting of main spindle box, Hydraulic Station is connected with the tail ejection device by oil pipe, be used to control and vertically move platform servomotor feed arrangement of lengthwise movement in lathe bed and place the lathe bed right-hand member, the platform that vertically moves that two ends are provided with vertical line slideway places in the lathe bed, the linear electric motors feed arrangement is installed on and vertically moves platform one side, the spinning roller device places the side of linear electric motors feed arrangement towards the lathe bed center, and the console that is used to control each mechanism kinematic is connected with each mechanism by control line.
