DE3203165A1 - Shears for bar-shaped workpieces - Google Patents

Abstract

The invention relates to shears for bar-shaped workpieces, in particular billets. A chute is provided at the outlet of the shears. So that a blade change can be carried out, the invention provides for a table to be attached to the chute in such a way that it can be pivoted in a horizontal position and is also vertically adjustable so that, to fit the blades, the table merely needs to be pivoted into a position which is located in front of the shears and in which it can receive the removed blades. It can then be swung to the outside, and the used blades can be replaced by new blades, which can also be prepared for fitting. The table can then be swung in front of the shears again so that the blades can be fitted. The vertical adjustability permits access to both the bottom and the top blade. A displacing capacity in the horizontal direction permits further improvement in the setting-up of the table.

Description

DESCRIPTION:

The invention relates to scissors for rod-shaped workpieces of the type specified in the preamble of claim 1.

Such scissors are Taekdt l according to DE-GM 19 58 483. The slide can be derived from its operating position wn that running at Icl?, e of the machine frame Pivot the axis upwards, whereupon the space immediately in front of the scissors becomes accessible, so that you can change the scissors knife, for example but with regard to the weight of the scissors knife and the need to Treating the latter gently is difficult. This is the starting point for the invention the task is to further develop the scissors mentioned in the introduction, that they can be effortlessly changed without significant additional design effort the knife allows both the change of the lower as well as the change of the upper knife should be relieved.

This task is determined by the proposal according to the marking part of claim 1 solved, for which the proposals of the dependent claims 2 to 6 Provide advantageous further development.

In this way one comes to an effective support of the developed or the knife to be installed on the table top, thanks to its height adjustability allows access to both the lower and the upper knife, so that both knives can be changed with the adjustable table top. About that In addition, preparatory work can largely be carried out outside the scope of the Scissors are made because the table is mounted in the guide sleeve by means of the Pivot bolt seed.

This makes it possible to bring the table to the position that would normally be used is designed as an inlet for the slide and during a knife change of practically bridged the table is required after the change has been completed however, the title again revolves around the swiveling outwards to gain access to the slide so that the latter take up the sheared-off sections and merge them into one can transfer the container located at the lower end of the slide.

The table, which can be adjusted in height and swiveled in this way, can according to a further proposal of the invention still an additional degree of freedom in that it can be moved horizontally In particular, it is useful to if it, together with the bolt carrying it, is parallel to the longitudinal direction of the knife is movable.

In this way he can easily be converted into a position, in the other preparatory work, such as the removal of a 'dismantled knife, the support of a fresh knife and the adjustment can be carried out.

The proposed movability is particularly easily achieved in that the slide itself has a support guide at the top and bottom, which allows the slide to be displaced in the horizontal direction.

The lower support guide of the slide expediently consists of the Am The base of the scissor frame is provided with a horizontal axis in which the slide is normally located is pivotable by means of corresponding bearing eyes. If you have been trained for a correspondingly long time Axis can be the slide by means of the bearing eyes mentioned but also on the axis move.

There is no need for pivoting for the upper support guide is made. Therefore, the upper support guide is basically realized by that on the slide mounted rollers on a rail located on the scissor frame expire.

The horizontal axis of of such a length that the table is not only out of the immediate area the knife, but at least in an outwardly pivoted position also from the entire scissor area can be swung out, so that preparatory work can be carried out completely unhindered at the table mentioned. For such work the table has attached angles, which allow the delivery of the knives from one and enable them to be taken over in a tilted position so that 5 accidents can be avoided.

For a further illustration of the invention, reference is made to the Reference is made to drawings relating to an exemplary embodiment. In it show: figure 1 the scissors with attached carriage in a partially cut side view FIG. 2 shows a plan view according to FIG. 1 with an outwardly pivoted table and the like n d Figure 3 the table in a lower and in an upper mounting position for a Knife.

The scissors 6 are carried by the machine frame 11, the fli. "13 of which around The purpose of a stable support is widened. The foot,. / Carries the elongated one Axis 7 on which the eyes 8 located on the slide 1 are mounted as well as are moveable The movability is in the direction of the straight double arrow 14 possible, while the pivotability is illustrated by the curved double arrow 15 is. In the position pivoted out of the operating position, the slide takes the Position 1 on.

The slide 1 carries at its upper end the guide sleeve 2, in which the bolt 3 is pivotable and also adjustable in height, for the purpose of height adjustment the guide sleeve 3 can be provided by means of a hydraulic cylinder. Farther 1 rollers 9 are mounted at the upper end of the slide, which in turn are on rails 10 run, which latter is located on the scissor frame 11.

The pickling 3, which can be moved out of the guide sleeve 2, carries on its upper end the table 4, on which angle 12 are built, the one designated by 5 Allow knives to tialten in a tilted position. Such a knife can be used in this situation is easy to apply. or removed. This is conveniently done in the in 2, shown position 4 'of the table, which pivots outward is. You can get it völ i i q iius the area of the scissors when the slide 1 by means of their eyes 8 on the horizontal axis 7 in the corresponding direction is moved. When the appropriate support of a knife is made on table 4 became.

it is in the working position, weighting the curved double arrow 16 pivoted, in which, for example, a previously placed knife 5 on the knife holder is brought up to then be firmly embedded in the latter. This process Fig. 3 illustrates, after which the measuring device 5 is pivoted in the direction of arrow 17 will. Depending on whether a lower knife or an upper knife has to be selected the table 4 in its lower position .0) used or by actuating a no longer shown hydraulic cylinder of the guide sleeve in the direction of the arrow es 1i; qhnbn.

so that the table 4 then assumes the position 4 '.

The outwardly pivoted position t1 'of the table shown in FIG. 2 4 is not only required for the purpose of loading, but also required during noniia 1 operation so that slide 1 is freely accessible for sheared sections. The sheared sections can by means of the Soft 19 of the slide 1 optionally passed in one or the other way are by the switch 19 according to the curved double arrow 20 in the one or is brought into the other position 19 '.

If the change in position of the table is to take place without fü.i this purpose the slide is movable or should be moved, so offers This has the option of pivoting the table from one with the bolt 3 To develop the arm separately and to move it horizontally on such an arm to fix.

Line option for this is illustrated by the dashed or

Dot-dash representation in Fig. 2, in which the risch mi; the reference number 4 'is provided. In this representation he is from init your bolt 3 corresponding to the curved direction arrow 16 pivotable arm by a dash-dotted line Play line separately. The arm can be parallel to this line with an attachment rail be provided that an attachment of the table 4 i @ under different distances permitted.
