Description
Technical field
The present invention relates to the non-round moulding and special-shaped bloated type and the correction of sealing of sheet metal component.
Background technology
Engine combustion tube changeover portion is owing to be after panel beating divides the semi-stamping moulding, to be welded again, so deflection is big, in order to guarantee the square opening shape, need proofread and correct square opening.Because the wall thickness of part is big, square opening is shaped as waist shape, the shape more complicated, and manual difficulties of calibration is big, and workman's working strength is high.And on punch press, proofread and correct with mould, need the complicated mould of a cover, both guaranteed not quality, efficient is also low.Adopt common hydraulic system, because system pressure is big, equipment volume is huge, poor reliability, and generally can only be to the bloated type of circular pieces.This has influenced the processing of many kinds.
Summary of the invention
The object of the present invention is to provide that a kind of correction mass is good, the high bloated type device applicable to multiple product of efficient.
The present invention provides a kind of irregular part type device that expands, and it is characterized in that: mainly comprise framework, workbench, feed mechanism, stationary table is on framework; Feed mechanism is contained on the framework, and the bloated piece more than 2 or 2 of ability horizontal slip is arranged on the workbench, and these are bloated, and piece is formed the block assembly that expands; The profile of bloated block assembly is the special mouth of part; There is bellmouth at bloated block assembly center, matches with center wedge, and center wedge is contained on the output shaft of feed mechanism.
During work, the part special mouth is placed on downwards on the block assembly that expands.When the output shaft of feed mechanism drives center wedge when the sharp direction of awl moves, the outside expansion of piece of expanding is proofreaied and correct the special mouth of part.
The irregular part provided by the invention type device that expands can be to each packaged bloated block reset jacking block that bloated piece guide pad is arranged and/or have back-moving spring that expands on its workbench, guarantee to expand the piece glide direction with reset.
The irregular part provided by the invention type device that expands, outer can the overlapping of its center wedge has lining, to increase the service life of center wedge.
The irregular part provided by the invention type device that expands; Its feed mechanism can be a hydraulic system; Hydraulic system mainly comprises pressurized strut, three position four-way directional control valve, hydraulic pump and fuel tank; The oil-in of three position four-way directional control valve is connected with fuel tank through hydraulic pump or the gas-liquid pressure-boosting pump that is connected to source of the gas, and the oil return opening of three position four-way directional control valve directly is connected with fuel tank, and two oil-outs of three position four-way directional control valve are connected with the piston both sides of pressurized strut respectively.
In the irregular part provided by the invention type device that expands, the oil-out of its three position four-way directional control valve and pipeline that the piston upside of pressurized strut is connected pressure regulator valve can be housed, with the operating pressure of the piston upside of suitable raising pressurized strut.
In pressure regulator valve and the pipeline that the piston upside of pressurized strut is connected Pressure gauge can be housed in the irregular part provided by the invention type device that expands, the oil-out of the piston upside three position four-way directional control valve of its pressurized strut and pipeline that the piston upside of pressurized strut is connected.
The irregular part provided by the invention type device that expands is equipped with positioning and clamping mechanism on its framework, to guarantee the part thick precision of type that expands.
The irregular part provided by the invention type device that expands, its advantage is: parts fixation is convenient with the location, and the precision of part processing is good, efficient is high, through changing module and suitable adjustment, applicable to multiple product.
