Description
Technical field
The present invention relates to the tubing processing unit (plant) in machining, particularly a kind of hemmer.
Background technology
In practical operation, a flange usually need to be set at the port of tubing to satisfy the demand, particularly metal pipe material, if at pipe end welding one circle flange, cost is higher, and the bonding strength between flange and tubing is not high, also higher to operating personnel's specification requirement.
For solving above-mentioned deficiency, produced flanger, as the Granted publication number disclosed a kind of device for turning edge of pipe-mouth of utility model patent that is CN201997588U, it comprises mould, positioning sleeve, oil pipe, hydraulic hand-pump and hydraulic jack, hydraulic jack is comprised of cylinder body and piston rod, described hydraulic hand-pump is connected with hydraulic jack by two oil pipes, the cylinder body of described hydraulic jack is fixedly connected with positioning sleeve, the piston rod of described hydraulic jack is connected with mould through positioning sleeve, and the mouth of pipe of described positioning sleeve and parts to be processed is suitable; This kind of turn-up device machining accuracy is low.
The disclosed flanging mechanism for metal pipe of the utility model patent of and for example authorizing publication number to be CN201711440U, it mainly comprises frame, wind, multidiameter, ladder roller and oil cylinder, multidiameter is through frame, wind is fixed on an end of multidiameter, the ladder roller is by the parallel frame that is located at multidiameter top of bolt, oil cylinder is fixed on the top of frame, and its cylinder bar is stretched in frame and is fixedly connected with bolt, the concavo-convex ladder of multidiameter coordinates with the concavo-convex ladder of ladder roller and is axially gapped; This kind of flange body is by constantly pushing tube wall between multidiameter and ladder roller, thereby make the stressed and perk of pipe end, to realize flange, it is opposing that the perk direction of its pipe end and ladder roller impose on the pressure of metal tube, this flange is because metal pipe-wall is subject to after enough large radial pressure producing to extend axially causing, and its flange place is due to thin by compression and, thereby make the bonding strength of flange and body lower.
Summary of the invention
The purpose of this invention is to provide a kind of hemmer, utilize this kind of hemmer to carry out flange to workpiece, the bonding strength of flange and workpiece body is higher.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of hemmer, it comprises frame, workpiece wall to be processed is applied and tilts with plane, the former place of this wall or the module of parallel or the pressure that overlaps, be located on frame and drive workpiece and rotate and can apply at workpiece flange place the roller group that the less angle that acts on the azimuth that pressure forms of workpiece wall to be processed with module is more than or equal to the support force of 90 degree.
The power that gives workpiece when the roller group outside workpiece the time, coordinates roller group module to exert pressure to workpiece, and the present invention is applicable to the workpiece in-flanges, otherwise is applicable to the flanging of workpiece.
Technique scheme, when the roller group is that workpiece is after the flange place provides support, the pressure that module acts on workpiece wall to be processed is the power that directly realizes flange, compare in background technology and authorize the disclosed technical scheme of invention that publication number is CN201711440U, the effect of module of the present invention is similar to the effect of ladder roller, thereby, in the time of can carrying out flange to the workpiece of same equal-specification, module of the present invention should be less than the pressure of ladder pair of rollers workpiece to the pressure of workpiece, therefore, the present invention is more laborsaving, is conducive to reduce energy consumption.
And authorize the disclosed technical scheme of invention that publication number is CN201711440U in background technology, can compress workpiece flange place, thereby cause the bonding strength of flange and body lower; The workpiece of so processing through the present invention, the support force place that its flange place gives in the roller group owing to being subject to module pressure bends naturally, the radian of workpiece flange place inside and outside wall bending equates, and workpiece is the metalwork for having better ductility often, therefore, when the wall thickness at flange place and workpiece are undressed, the gap of the wall thickness at this place is less than the suppressed range of background technology, thereby, improved the bonding strength of flange and workpiece body.
And authorize the disclosed technical scheme of invention that publication number is CN201711440U in background technology, its flange principle is because metal pipe-wall is subject to after enough large radial pressure producing to extend axially causing, thereby visible, often be difficult to realize the processing to the larger flange width of needs, the distance that is workpiece bending place and workpiece perk end is larger, also often be difficult to realize the processing of the thicker workpiece to wall to be processed, therefore, this technical scheme is larger to the specification limits of workpiece, to the width of flange, also limits larger; So to act on the pressure of workpiece wall to be processed be the power that directly realizes flange to module of the present invention, and therefore, the present invention the gives workpiece size of power to module is less, thereby makes the present invention can be applicable to the workpiece of more specifications, also can realize the processing of larger flange width.
