Sheet metal working machine

The price increase relates to a sheet metal processing machine for separating or trimming sick panels and for preparing the cut surface of the section of the sheet metal remaining on the system table by shaping the cutting edge accordingly for a weld to be made later, for example a Y-, X-9 Y- or Tulip seam.

To prepare the weld seams on metal sheets even in more recent times proceed in the manner that.'the sheet metal on a conventional. {guillotine 'or a distilling machine to the required level To be cut to size «Which type of guillotine shears is preferred here, that depends in the individual case on the operational circumstances. Should metal sheets only be trimmed table shears with circular knives can be used for Use it as it does this work

ISt _{5 is} irrelevant if the sloping sheet metal strip winds up in a helical manner. If, on the other hand, thicker metal sheets are to be separated into two further parts to be processed, the use of circular knife scissors becomes inefficient, at least with thicker sheets. As already stated, the falling piece of sheet metal with guillotine shears with circular knives suffers a relatively strong deformation and cannot be used for further use without the appropriate machining direction. As a rule, guillotine shears with knives that can be moved parallel to one another, so-called guillotine shears, are used for such work processes. In the case of the last-mentioned guillotine shears, the movable knife of which has a converging inclination of up to about 4 ° in relation to the fixed knife, the pieces of sheet metal experience practically no change in shape and can be used for further use without notification; after the cutting or trimming of the sheet metal, these are also used Time still from the guillotine to one. The bevelling machine moved to a different location. There the corresponding adjustment is made to the required seam shape. This way of working is extremely time-consuming, requires additional operating personnel, the use of transport and lifting equipment and the purchase of two tool machines.

To remedy this deficiency, guillotine shears with cutter bars in the table have already been proposed5 To train way that the same instead of the knife bar guided in vertical prisms or columns is designed as a segment of a roller, on the cylinder surface of which two fly blades are arranged one after the other are »The segment can be swiveled around two axes that are relatively far to the rear, so that at the cutting edge as a result of the relatively small portion of the circular movement, the cut surfaces each run almost tangentially., The lower The pivot axis is the lower knife, the cutting knife, and the upper pivot axis is the upper knife for the Machining of the welding edge assigned «, The swiveling movement of the upper knife runs approximately in a tangential plane inclined to the cutting surface «,» driving a pivoting movement, the segment changes its pivot axis. In this way, the lower knife is used to first cut or trim the Sheet metal and then using the upper knife to prepare the welding edge by making a bevel cut.

Another pair of guillotine shears is also known at

the guides for the cutter bar are more conventional Design can be inclined »After the shearing process, the guides are inclined towards the cutting surface Level brought and the movement of the cutter bar repeated »This creates an angled cut the welding edge ο

With the machines described above, Y or Y-S seams can be prepared very well »33a in The X-Uaht is just as often required in welding practice It’s like 7- or T-mowing, a must for such machines forced the pieces of sheet metal remaining on the system table turned and a new one Finishing process are supplied, however, tulip seams cannot be used with the facilities described be prepared -! "Not just this defect, but also the relatively very high acquisition costs the above-mentioned guillotine shears therefore prove to be a disadvantage that is particularly important in practice.

learners are familiar with table hairs with circular knives? which have a second circular knife that tracks the actual cutting knife and its The axis of rotation is inclined with respect to the cutting knife. on

In this way, the following circular knife with an inclined axis of rotation crops the upper cutting edge and creates Depending on the setting, a weld edge shape for a Y or Y seam. Also with this facility must the metal sheets are turned over when the welding edges are to be prepared for X-O seams. Even it is again not possible to prepare the welding edges of the metal sheets for a tulip seam. Ss from this G-round further developments have come onto the market instead of the following circular knife have a planing device with planing chisels that can be used in different ways «Since the separating Circular knife has to be guided in a carriage along the cutting edge anyway, this can be done in the same Slide arranged planing device can be seen as quite obvious, especially since it is by means of this It is now possible to set up the welded edges of the metal sheets for all common seam shapes to prepare »In practice, however, it turns out to be extremely disadvantageous that, as already mentioned above mentioned-, guillotine shears with circular knives a considerable Cause deformation of the sloping section of the sheet metal, panels and therefore aim such machines Separating and dividing sheet metal can only be found suitable with strong reservations.
