The device contains a frame 1, where on the top plate 2 are mounted

the mechanism for supplying 3 products to the treatment area and symmetrically on either side of the assembly 4 loading mechanisms 5, 6 removing armature from the surface; products and mechanisms 7 V exiting the armature from holes. The operation of the mechanisms is carried out by a three-way pneumatic tap 9 and pneumatic distributors 10 and 11). Q The mechanism 3 for supplying products to the treatment zone is made in the form of a movable carriage 12 with a rack 13 and. two spaced sockets on the ends of the carriage 14 15. The sockets are provided with under-; J5 is spring loaded with zipper frames 16, the top bar 17 of which is made with protrusions 18. The carriage 12 is moved by a pneumatic cylinder 19 through a rod 20 contacting 20 with a gear rack 21, and the gear 22 block, is rigidly fixed on one side The other side pneumatic cylinder stem 199 is mounted on the end of the rail 21 movably 25 with a gap between spring-loaded washers 23 i 24. End positions of caps. retractors 12 are fixed by stops 25, and removal of the pin-on strap from the socket to the loading position is provided by a pneumatic cylinder rod 26. The release mechanism is blocked from the reinforcement surface of the product as two blocks with a set of cutting tools located on both sides of the workpiece. Each block consists of a housing 27 with an axis 28, on which the holders 29 of the upper and lower knives are alternately mounted with the possibility of swinging. ; The holders on one side of the axis are spring-loaded spring 30, and on the other hand, abut against an adjustable stop 31, which provides the setting tool relative to. the treated surface of the product. Each holder 29 is provided with a tool socket 32, and a locking groove 33 is made on the rear side of the socket. The tool is manufactured in the form of an axis 34, on one side a working head with cutting elements is located on the one side. 35, sharpened at a sharp angle oi, and on the other hand, the hole for pin 36, Pin diameter 36 is smaller than the width of the locking groove 33, which ensures that the tool is shown in the holder slot around its own axis at an angle p,. The tool is installed in the deo30 sockets.

residents on both sides of the surface to be treated. Moreover, the cutting edge of each subsequent tool is installed with an offset in the horizontal plane. This allows you to expand the working area of the active KOH-I tact of the knives with the surface to be treated. If necessary, processing of the product only from the bottom side, instead of the cutting tool, you can install smec rollers 37 on top. The rollers provide rigidity during processing and do not damage the upper surface of the workpiece. In addition to a group of knives that are independent of each other, spring-loaded abrasive wipers 38 are installed on both sides of the casing at the ends of the axle, which increase the efficiency of removing the layer of scrap removed from the knives. The mechanism for extracting the flap from the grooves and the holes of the reinforcement is made in the form of a movable plate 39 mounted on the columns with punches, which provide extrusion of the flap while the plate is moving downwards. The lifting and lowering of the plate is provided by a pneumatic cylinder 40,,: The extrusion mechanism is positioned at the distance from the loading zone, each at a distance equal to the distance between the two carriage slots.

The machine works as follows. Workpiece 41 — A tape with transistors in a plastic case is loaded into the socket 14 of the carriage 12, which is in the leftmost position. When switching the pneumatic tap 9, the rod of the pneumatic cylinder 19 moves to the right. In this case, the rod 20 moves along the end of the rail 2.1 between the washers 23 jj 24 and turns off the pneumatic distributor 10, which gives a command to turn off the pneumatic cylinder 26, The rod of the pneumatic cylinder 26 under the action of springs descends and the pressure frame 16 presses the product in the socket. The protrusions 18 of the upper clamping bar 17 enter the gaps with the devices, fix the position of the tape and squeeze out the gap between the devices, which falls down into the pan along the bevels, and JipH pulls the rod 20 towards the next movement of the rod. with the washer 24, moves the toothed rack 21 and the gear block 22 and the rail 13 to the right of the carriage 12. The tape being processed is supplied to the mechanism for removing about 6 from the surface of the reinforcement:

tours. The knives 35 are worn out at the end of the band, unfurled in the sockets 32 of the holders 29 and, turning on the axis 28, overcoming the force of the spring 30, are applied to the surface being machined. ness During the course of the carriage 22 to the right, the front end of the cutting edge works with skin, which removes the splash from the surface of the product or breaks its adhesion to the metal.

The oblo layer is carried out by spring-loaded abrasive cleaners 38 .. After a partial removal of the block from the surface of the product, the tape slot fits into the position of the oblo from the holes and grooves. The carriage 12 abuts against the stop 25, and the pneumatic cylinder 19 while continuing to move to the right, it compresses the spring with the rod and switches on the pneumatic distributor t1, which commands the activation of the pneumatic cylinder AO and pneumatic cylinder 26, the rod of pneumatic cylinder 40 lowers the plate 39 with the punches down. At the same time, the punches enter into the holes and grooves in the reinforcement and squeeze the remaining bald in them. Simultaneously with this, the pneumatic unit 26 lifts the clamping seat on the second nest 15 of the carriage 12, which has approached the loading unit. The next tape is loaded into the second slot 15 and the pneumatic tap 9 is shifted. The pneumatic cylinder rod 19 moves to the left, retracts the rod from the pneumoregular limiter 11, thereby turning off the air supply to the pneumatic cylinders 16, returning the pneumatic cylinder 40, returning to its original position, raises the plate 39 up and removes the punches from machined rebar holes. The pneumatic cylinder rod 26 goes down, and the belt 41 then stops at the second nest 15. Further movement of the rod of the pneumatic cylinder 19 of the rod 20 rests on the cushion of the washer 23 and moves the gear unit 22 and the rail 13 of the carriage 12 through the rail 21 to the left in the iodine position. At the same time, the processing of the second grandfather; ali takes place according to the cycle previously described by the second mechanism 5 ni obli from the surface and, during the 7, extrusion oblo from the holes, located-1 to the left of the loading unit 4, And the first part re-passes under the knives. and abrasive cleaners.

Cushion around its own axis 34 and axis 28, overcoming the force of the springs 30, land on the surface to be machined and strip off the remains of the overhang with the rear end of the cutting edge. When the carriage 12 returns to its initial position, the pcs. 20 includes a pneumatic distributor 10, which controls the pneumatic cylinder 40 of the extrusion mechanism 7 and the pneumatic cylinder 26, the pneumatic cylinder rod 40 lowers the plate 39 of the second extrusion mechanism down and the pneumatic cylinder 26 raises the frame 16 with the presser bar 17 up, thereby freeing the treated tape. The treated tape is discharged from the socket 14, and the next one is installed in the socket. Further, after switching the pneumatic tap 9, the cycle is repeated.
