Description

2, the device according to claim 1, which is ticking by the fact that the retractable stops are made in the form of a fixed and movable wedges installed with the possibility of interaction with it,

3. The device according to claim 1, which is the fact that the regulation The invention relates to ancillary equipment, procured production of engineering enterprises and can be used in cutting devices for the step-by-step material feed.

The purpose of the invention is to increase productivity when cutting a set of blanks of various lengths.

FIG. 1 image of a device for the step-by-step material feed, general view; in fig. 2 is a view A of FIG. one; in fig. 3 - clean stop, general view; in fig. 4 - template general view.

On the basis of the proposed device, a trolley 2 is mounted with wheels 3 moving along a welder 4, a live roll with rollers 5, a retractable stop 6 and an adjustable stop 7. On the trolley 2, the rods 8 of two power cylinders -9 fixed on base 1 are attached. Base 1 is mounted two horizontal m. ix. screws 10, which can rotate synchronously due to two worm gears 11 connected by common shafts. 12. Worm pairs are mounted on two nuts 13 and 14. On base 1, support 15 and tangles 16 and 17 are fixed. Templates 16 and 17, have recesses 18 and 19, a bracket is fixed to cart 2 and suckers 21 An additional suction device 22 is installed in the center of trolley 2. Each abutment 6 consists of a housing 23 in which: a power cylinder 24 is placed, the stem of which is connected to a movable wedge 25 installed with the possibility of interacting with a fixed wedge 26. The base 1 is fixed. with to a bed of scissors 27 or to beds of other metalworking

machine tools. Scissors are equipped with clamps 28. An adjustable stop 29 is fixed to the clamp 28, which interacts with two microswitches

5 30 and 31. A microswitch 32 is placed above one of the suckers 21. Two microswitches are mounted in the lower part of the wedge 25. 33 and 34. The microswitch 34 interacts with the side front side of the template 17, the microswitch 33 with the top: its side 35 of the template 1 7. On the nuts 13 and 14 there are microswitches 36 and 37, which

5 interact with an emphasis 38 fixed on trolley 2. Metal sheet 39 is laid on rollers 5 of the roller table.

The device for the step-by-step material feed 20 operates as follows.

Suppose that you need to cut a sheet of metal with a length of 20QO mm into four lengths of 10, 100, 140 and 25 1750 mm. ;

The stop 7 is fixed on the base 1 so that the distance between the stop 7 and the cut line is 2300 mm. Then the sheet 39 30 is placed on the roller conveyor 5 against the stop 7. The space of 300 mm is formed between the edge of the sheet 39 and the cutting line. The templates 16, 17 are laid to the fixed stop 15, the length of which is respectively equal to 140 and 100 mm. Then, the screws 13 are moved by rotating the screws 12 so that the carriage 2 moves forward and a distance of 40 -310 mm is formed between the stop 17 and the rod 25, so that division and digital symbols are applied on the carriage. (not shown).

The adjustable stop is made in the form of a screw pair, the nut of which is installed with the possibility of interaction with the driving carriage.

4. The device according to claim 1, 1 and 2, is that the working surfaces of the templates are inclined.

The device is fully adjusted and ready to automatically cut the sheet into segments of 10,100, 140 and 1750 mm. To do this, include suckers 21, which are stuck to the metal sheet 39. Going down, the suckers by means of the microswitch 32 turn on the power cylinders 9. The rods 8 are swiveled and move the v carriage 2 (to the left in Fig. I) until the stop 17 meets microswitch 34. Together with cart 2, the suckers 21 move and the sheet 39 is moved by 310 mm. When the stop 17 is encountered with the microswitch 34, the scissors are turned on, which cut the metal sheet (10 mm) extended beyond the cutting line. When lowering the institute clamp 28 scissors down microswitch 30 is activated, which turns on the power cylinder 24. The cylinder rod raises the wedge 25.

At the same time, switch 30 turns on cylinders 9. When cylinders 28 are lifted, they are turned on by microswitch 31. Cart 2 is moving forward, template 17 communicates with micro switch 33, which turns on cylinder 24. Wedge 25 begins to descend, slides along template I7 surface and by-

10 falls into the recess 19 where it meets with the pattern 16. Together with the carriage 2, the metal sheet is advanced by 100 mm, since the length of the pattern 17 is 100 mm. Then the cycle is repeated and the device cuts a 140 mm cut, the remainder is equal to 1750 mm. Thus the whole program is executed-. on. Suction pad 22 serves to turn the sheet and nuts 14 to cut into

2Q equal billets (in this case they are set at the required distance from the side stand of trolley 2).
