Abstract

The invention relates to a sheet metal edge knurling device and method of sheet metal. By adopting a rolling bending technology, a side edge of the sheet metal is rolled in an asymptotic manner through the linear movement of a plurality of groups of rollers, on the premise of not forming the damaging, the accuracy in edge folding can be realized according to a predetermined direction and a predetermined angle, so that the edge folding precision and the appearance quality of the sheet metal surface can be improved. The sheet metal edge knurling device comprises an edge folding die, a press plate and a roller assembly, wherein the edge folding die is used for carrying the sheet metal which is transported to the edge folding die; the press plate is used for fixing the sheet metal onto the edge folding die along the vertical direction; and the roller assembly is provided with a roller support which is provided with at least two groups of rollers. All rollers are sequentially arranged along the linear direction which is vertical to the fixed position of the sheet metal. The roller support drives the rollers to sequentially roll the same side edge of the sheet metal along the linear direction, since the advancing direction of the rollers is vertical to the side edge of the sheet metal extending out of the edge folding die, the rollers sequentially rolls the same side edge one by one, and the side edge bending angle can be in an asymptotic form.

Description

Metal blank binding device and method thereof

Technical field

The present invention relates to a kind of side rolling contour machining equipment for sheet metal and rolling processing method thereof, belong to Machine Design and industrial automation.

Background technology

The equipment and control technique that is used at present the metal blank flanging both at home and abroad, adopt comparatively at large one-step moulding method, sheet metal for sheet metal thickness＜1mm then more adopts multistation flanging technique, be that plate is sequentially finished the multiple tracks bending operation and the final flanging that forms than wide-angle between a plurality of stations, otherwise more easily form crack or angle and cross curved phenomenon, thereby cause plate loss, increase production cost.

Formerly applying for a patent of following content and for example disclosed, application number ZL01808009.X, name is called crimping unit, its scheme is that crimping unit comprises an adjustable shelf (3) that is provided with flanging hyoplastron (32) and pre-flanging hyoplastron (31), a pedestal (5), the balladeur train (4) that adjustable shelf (3) are installed on it, and at least one motor (M1, M2), motor (M2) links with balladeur train (4).Balladeur train (4) when motion by at least one linear guide (50) guiding, to guaranteeing the rectilinear motion of adjustable shelf (3) when flanging and the pre-flanging.

Above-mentioned formerly utilization and application are flanging shaped device and technique, for sheet metal and inapplicable, have traced it to its cause two.The one,, the thin plate pliability is relatively poor, and directly bending is easy to injury, such as diffraction shape crackle; The 2nd,, be difficult for to aim at the plate center and form the bending scale error, have influence on plate following process quality and result of use.

In view of this, the special present patent application that proposes.

Summary of the invention

Metal blank binding device of the present invention and method thereof, its purpose is to solve the problem of above-mentioned prior art existence and takes roll extrusion bending technique, the asymptotic expression roll extrusion plate side by the Linear-moving of many groups roller, under the prerequisite that does not form damage, realize accurate flanging by predetermined direction and angle, to improving the presentation quality of flanging accuracy and panel surface.

Another goal of the invention is, forms the accurate location of plate before the bending, thus improve fixed in precision, improve the flanging quality further.

For achieving the above object, described metal blank binding device mainly includes:

Hemming die is used for carrying the metal blank that is transferred so far;

Pressing plate is fixed in metal blank on the hemming die along vertical;

The roller set assembly has the rolling wheel support of installation at least two group rollers.

Wherein, whole roller is along being arranged in order with metal blank bearing perpendicular linear direction.

Based on such scheme, when metal blank be transferred and by pressing plate along vertical be fixed on the hemming die after, under the driving of drive unit, rolling wheel support drives the in turn same side of roll extrusion metal blank of many group rollers property along the line direction, because roller direct of travel and metal blank bearing are perpendicular, namely to extend the side of hemming die perpendicular with metal blank, organizes roller more and carry out successively for the roll extrusion of same side, and the side edge bending angle can be gradual.

For the sheet metal of thickness＜1mm, the process of roll extrusion bending progressively occurs, and the bending program is accumulated step by step, can better protect plate injury-free.

And pressing plate is fixing more firm for plate, vertically carries out the accidental movement that roll extrusion also is difficult for causing plate, and accuracy of alignment is higher.

For embody better progressively, the effect of roll extrusion flanging gradually, the following further improvement project that can take:

Described roller is installed on the longitudinal center line of rolling wheel support, angle gradual change with metal blank, the setting angle variation that is the two adjacent groups roller is certain value, thereby the bending angle of organizing roller formation is to accumulate equably more, be easier to form exactly interim bending effect, and finally form not damaged, accurate flanging.

For implementing simultaneously the dual-side flanging operation of same plate, can symmetrically arranged 2 row rollers be installed at rolling wheel support, when same rolling wheel support moves, 2 row rollers respectively for the plate dual-side along its vertical direction, side by side carry out same degree, ground roll backfin limit gradually.

Based on above-mentioned design concept, after using above crimping unit, the present invention has also realized following metal blank edge covering method simultaneously:

Metal blank is transported on the hemming die, and at least one side extends hemming die;

Pressing plate is fixed in hemming die along vertical with metal blank;

Driving rolls group assembly moves along the perpendicular linear direction of metal blank bearing, at least two group rollers same side of roll extrusion metal blank in turn in this process, thus it is rolled into the flanging of setting bending angle.

More refinement is to organize roller for the roll extrusion flanging angle gradual change of the same side of metal blank with preferred corrective measure more.

For improving flanging production efficiency, can symmetrical be installed on 2 row rollers of rolling wheel support, the dual-side for metal blank carries out the roll extrusion flanging respectively.

Content to sum up, metal blank binding device of the present invention and method has the following advantages and beneficial effect:

1, realize a kind of roll extrusion bending technique, under the prerequisite that does not form damage, realize accurate flanging by predetermined direction and angle, the presentation quality of flanging accuracy and panel surface is all higher.

2, by locating accurately, can improve further surely middle precision and flanging quality.
