Description

The invention relates to rolling equipment, in particular, to devices for holding, pressing, or supplying and rolling during its processing. A device for clamping a rental-on the basis of which a rotary lever with a pneumatic actuator and a plate tl is mounted is known. The disadvantage of this device is the difficulty of mechanizing end-trimming due to the need to rotate the roller conveyor. The purpose of the invention is to increase productivity by mechanizing end-trimming when cutting is not rolled with a disk cutting tool. This goal is achieved by the fact that in the pressing device, on the basis of which a rotary lever with a pneumatic actuator and a plate is mounted, the latter is equipped with a rotary axis with a scraper rigidly fixed on it and a double-shouldered lever with a drive for moving it while one arm is mounted with the possibility of interaction with the actuator, and the other with the locking bar inserted into the device, propagated in the vertical groove of the plate. FIG. 1 shows the proposed device, top view; in fig. 2 is a cross section A-L in FIG. one; in fig. Fig. 3 section bb in Fig. 1; fig. 4 - p-cut BB in FIG. one; in fig. 5 - fold cut GG in figure 1. . The rolling clamp device consists of a base plate 1, on which a four-section roller table is installed, consisting of two fixed sections 2 and 3 and two movable plates 4 and 5. Each move on the plate by rollers b rests on rails 7 fixed by racks 8 on the base plate, and bears the pivot axis 9, to which the scraper 10, tongs 11 and 12 are rigidly connected. The lever 11 is pivotally connected to the rod of the pneumatic cylinder 13, and on the lever 12 the lock bar 14 is mounted, which is installed in the vertical grooves of the Base plate plate 1 has Cuts 15 for locking slats, cuts 16 for lowering centering trim 17, cuts for roller 11gang 18, cutout for passing saw blade: 19, cuts for pivoting levers 20 and 21 that are hinged on the base plate and connected to a driving pneumatic cylinder 22 each. Under the notch 16 there is a sloped plate 23 and a conveyor of the end trim 24. A rolled strip 25 is supported on the rollers of the roller table. The device works as follows. The strip 25 rolled into the cutting zone of the saw blade 19 is fed by the rollers of the roller table 18, and the direction of the strip is provided by fixed sections 2 and 3 of the bead. The strip is clamped during cutting by the movable plates 4 and 5 and the pivoting levers 20 and 21. When the strip is clamped, the movable plates occupy the extreme right position (in this position the plate 5 is shown in Fig. 1 and Fig. 3). Cleaning the end trim 17 is carried out by moving the movable plate to the extreme left position (plate 4 is shown in this position in Fig. 2 by means of pneumatic cylinders 13. At the beginning of the work the movable plates 4 and 5 are in the extreme right position. For ETS5M axis 9 with scrapers 10 and levers 11 and 12 rotated by angle 9 (Fig. H.) With this position of the levers 12, the retainer bar 14 enters the notch 15 of the base plate 1 and fixes the position of the movable plate strictly. When moving the strip 25 along the roller conveyor, the swivel arms 20 and 21 occupy a position below the base level plates (Fig. 2). When these levers are rotated by means of pneumatic cylinders 22, they press the strip against the movable plates (Fig. 3). The forces that arise during this, as well as the forces that arise when cutting the strip, are perceived by the retaining strip 14 and transferred to the base plate 1.. When trimming, the front K-nipple of the strip is pressed against the plate 4 (not shown /. After the end of the cut, by turning on the pneumatic cylinder 22, the strip is released and the corresponding pneumatic cylinder 13 is turned on to move the plate 4 to the left. In this case, first, the axis 9 is rotated clockwise, which ensures that the scraper 10 is placed in a horizontal position and the locking bar 14 is withdrawn from the groove 15 of the base plate 1. Only after this the movement of the movable plate begins, at which the rollers 6. roll along the guides 7. At the same time, the scraper 10 captures the front end trim 17 and moves it along the base plate. When the plate 4 exits to the leftmost position, the trim 17 17 hits the inclined plate 23 and then the conveyor 24. After that, by reversing the air The cylinder 13 plate 4 returns to its rightmost position. When reversing, the axis 9 first rotates at an angle 3, and then the plate begins to move. This allows the scraper 10 to freely pass over the rental bar. When moving the movable plate to the right, the retainer plate 14 slides along the base plate 1, D In order to eliminate the locking in the middle part of the path, the right edge of the notch 16 is made under, upp (l (.tiKr. 2, which should be less than the calculated friction angle, determined from the conditions of the locking of the locking bar along the inclined loskosti.

When trimming the rear end, the strip presses against the plate 5 swivel

lever 21. Cleaning the rear end trim by moving the plate 5. The sequence of operations is the same as when cleaning the front end trim.

Thus, the application of the proposed device allows full. to mechanize end trimming.
