DE1627256C3 - Scrap shears with pre-compaction of the filled scrap - Google Patents

Description

ability is particularly beneficial in those cases where bulky and stiff scrap pieces are to be compacted.

After completion of the compression pivoting movement of the smooth side wall 4, the stepped Slide 3 moved by the hydraulic cylinder 8 in the feed direction, whereby the stepped with the Slide 3 toothed scrap in the direction of tamper 5 and knife 6 is moved. During the subsequent Return stroke, the slide 3 loses its engagement in the scrap located in the filling box. When the smooth side wall is pivoted again against the stepped slide 3, which has been held again the filled scrap then comes back in other places with the vertical working edges of the stepped slide 3 engaged.

Tamper and scissors located filling box, · Of the disadvantages mentioned above, the one long side can be limited by a smooth clamping in the guide after a known side wall and on the opposite side by a publication in the magazine »Scrap is a slide that is in one in Spit Age, October 1964, inside of the cover sheet arranged at an angle to the main inlet direction by avoiding the movable side guide by means of hydraulic cylinder sliding wall of the filling box at one end, characterized in that vertical axis rotatable
in a known manner, the smooth side wall (4) on The invention is based on the object the end of the scissors around a joint (11) with scrap shears of the type mentioned above vertical axis-swiveling and 15 power requirement for the pre-pressing of large sperridaß the slide (3) in the feed direction like scrap, such as B. pipes, and decrease step is the construction effort for the drive of the moving '· . borrowed to reduce the side wall of the hopper. This object is achieved according to the invention in that the smooth side wall is in a known manner at the scissors-side end pivotable about a joint with a vertical axis and that the Slide is graduated in the feed direction. The advantage achieved with the invention is ins-35 special in that the pre-compression force is locally applied The invention relates to scrap shears that can be brought forward, that is, the operator can compact the filled scrap in a bers with the vertical working edges bulky and filler box, which is on one long side through particularly stiff scrap objects, such as B. Pipes, a smooth side wall and this opposite 30 buckle locally, whereby the total power requirement is limited by a slide, which decreases in a force application that is arranged to compress compared to a multi-surface acute angle to the main inlet direction,
th guide, displaceable by means of hydraulic cylinders An additional advantage of the invention is. that when pre-pressing scrap with low During the pre-compression in the filling box, the 35 rer piece size takes the place of a batch-wise leg the most varied forms of storage Scrap can come up to the passage width of the dispatch, since during the cutting scrap shears compressed. dens the scrap shears through the filler box Known is a scrap shears with pre-compression pivoting the smooth side wall to open and to open the filled scrap, in which the in the opened pre-presses can be closed again,
th filler box filled scrap load by ■ An embodiment of the invention is shown in the closing of the filler box attached to the fixed longitudinal wall of the 'drawing in a top view, partially cut, and is described in more detail below. Clearance height of the scrap shears and. then the one in front of the knife guide frame 7, in which the by moving the movable side wall in 45 tamper and the knife 6 are guided vertically, in the direction of the fixed side wall on which the filling box 2 is compressed with a fixed side passage width of the scrap shears, and one at the end of the scissors side with the movable side wall is guided at its ends in a smooth side wall 4 arranged parallel to a joint with a vertical axis by means of a hydraulic cylinder 9 pivotable at an acute angle to the main inlet direction (German 50) Utility model 1 948 587). The fixed side wall 1 is at an acute angle to The disadvantage of this known design is that the main inlet direction (feed direction) is that when pre-compacting bulky scrap with scrap arranged during the 55 length of the fixed side wall extends and the stepwise advancement of the pre-pressed scrap feed direction in a tapering manner stepped strand for cutting no scrap is in the, the length of the individual stages of the same length filling box are refilled. Are more serious. The slide 3 stepped in this way, however, has the disadvantage with the Hyist that it can be moved back and forth with a handle of the sliding side wall along the stroke length, which is slightly shorter than a step length, due to the simultaneous hydraulic cylinder 8.
The stepped slide 3 is stationary while the large pipe must be pressed together smoothly over its entire length at the same time as the sealing pivoting movement of the pivotable one. For this purpose, a raised side wall 4 is still and then acts as a fixed rather force application, which is only due to a counter-bearing. The operator can shut down the stepped drive of the movable side wall of the filling cup 3 at any point within a correspondingly large construction effort for the displacement 65 of the stroke of the hydraulic cylinder 8 and thus the least can be covered. Another disadvantage is that the vertical step edges act on the protruding force from the fact that the scrap to be compacted is to be selected during the prepressing. This option
