Automated technological complex for cutting shaped and long products contains a receiving rack 1, made in the form of a trolley with a drive mounted on the track.

Parallel to rack 1, a tilter 2 of workpieces is installed, made, for example, in the drive gear swivel 3. Parallel to tilter 2 is a feeding roller conveyor 4. Above the rack 1, tilter 2 and feeding roller conveyor 4 a ramp 5 is mounted on which the arm 6 is mounted with electromagnetic-type grippers 7 for single-piece disassembling of the bundle of original blanks located on rack 1, and placing them on tilter 2 and on the feeding roller table 4. A press 8 is placed along the axis of the feeding roller table 4, behind which the receiving roller table 9 is installed. Between the feed roller 4 and the press 8, a trolley 10 with a waste container is placed on the rollers, having the ability to move in a direction perpendicular to the axis of the feed roller table 4. A trolley 11 with a container for short cut parts is installed on the rollers 8, having the ability to move a direction perpendicular to the axis of the receiving roller 9. Next to the press 8, there is a shop of 12 interchangeable inserts, and to the side of the receiving roller 9 is a container 13 for long items. On the frame 14 of the supply i of the roller table 4, two-cylindrical guides 15 are installed, between which a rack and pinion 16 is placed. On the guides there is a carriage 17 moving along the rollers 18 from the drive 19, for example a hydraulic motor connected by a gear 20 with rail 16 and provided with a mechanism for measuring the path of its movement (not shown). A lever 21 is mounted on the carriage 17, carrying the gripper 22 and having the possibility of rotation from the actuator 23, for example a hydraulic cylinder, for lifting and lowering the gripper 22 relative to the feed roller 4. The gripper 22 is made in the form of two double-arm levers hinged in the housing 24 on the axis 25 26 and 27, installed with the possibility of rotation in the vertical plane.

One ends of the arms that have long slots are pivotally connected

four

by means of axes 28 with sliders 29 and 30 mounted in parallel on guides 31 rigidly fixed in housing 24. The slide 29 is connected to the brush 32 of the power cylinder 33, and the slide 30 is connected through the hooks 34 and bar 35 to the cylinder 33. the free ends of the levers 26 and 27 are articulated clamping jaws 36 in the form of two-prisms. The housing 24 of the gripper 22 is pivotally mounted by means of an axis 37 on the lever 21 of the carriage 17.. On both sides of the axis 37 springs 38 are placed, acting on the body 24 and the lever 21 and supporting the body 24 parallel to the support plane of the roller table 4. The feed roller table 4 is made as mounted on the frame

14 supporting drive rollers 39, placed at an angle of 30 to the horizontal plane. In the middle part of the rollers 39, annular slots are made for unhindered passage when

moving the carriage 17 of the lower clamping jaw 36, located in a number of cases when the workpiece is gripped below the support surface of the roller table 4. Each roller 39 has an additional roller 40 located at the level of its support surface, having a length that overlaps the width of the roller slot 39. The rollers 40 are mounted on the levers 41, one shoulder of each of which is associated with the rod of the power cylinder 42, and the other with the spring 43 for lowering the rollers 40 below the level of the annular slot of the roller 39. Between the rollers 39, perpendicular to them, are installed

- side drive rollers 44, having the ability to move, required when changing the type and size of the workpieces, along the axis of the support roller 39 from the drive, for example, running

screw (not shown), behind the press 8 on the axis of the feeding roller table 4, a receiving roller table 9 is installed. The frame 45 of the roller table 9 is mounted on rollers 46 on rails with the possibility of longitudinal movement from the power cylinder 47 mounted on the foundation.

On the frame 45 of the axis 48, the frame 49 (FIG. 8) is hinged with drive, for example, from hydraulic motors 50,

rollers 51 arranged parallel to rollers 39 of the feeding roller table 4. Frame 49 is connected to frame 45 by a shock absorber 52, for example, a spring one. When cutting the front end of the frame 49 utap515

is cast and returned by the shock absorber 52 to its original position. Between the rollers 51, lateral rollers 53 are arranged perpendicularly thereto. Rollers 53 are mounted on levers 34 gaternally mounted on frame 49 and mounted for movement along the axis of rollers 51 from an actuator, for example, a lead screw (not shown). The levers 54, in turn, are connected to the rod & m of the power cylinders 55, hinged on the frame 49 and turning the levers 54 with the rollers 53,. to the location of the latter below the level of the rollers 51. On the frame A9 an inclined tray 56 is mounted, along which from. the cut blanks are rolled into container 13,

Dp removing the dies 57 from the press 8 when they are replaced on the latter, cantilever guides 5.8 are mounted parallel to the axis of the receiving roller table 9 and located in the plane of movement of the stamp 57 on the press table 8. Each stamp 57 of the replaceable magazine 12 is provided with a locking element made, for example , as

 the tooth 59. The frame 45 is provided with a mating part of the locking connection, made in the form of, for example, two hinged levers 60, connected at one end to the power heading 61, and the other at engagement with the tooth 59. On the stamp 57 tray 62 is installed to remove short cut pieces.

The operation of the automated process complex is as follows.

I

The complex provides for the operations of cutting and punching holes for shaped and special steel, as well as cutting for long products. The press equipment with a die tool is used as the process equipment.

On the complex you can handle everything. types and dimensions of shaped sections, special profiles that allow cutting in a stamp and having a horizontal shelf, for example, a carriage rack, as well as forty-rolled products of limited sizes (for example, a circle with a diameter of up to 30 mm).

Optimum cutting conditions for shaped steel on a press with a clamp tooling require wall positioning.

206

its sections are at an angle, for example 30, -. to the horizontal plane, for which the supporting rollers of the feed and receiving roller tables are located at the same angle to the horizontal plane. Optimum conditions for the cutting of rolled products require, in addition, a symmetrical arrangement of the stamp pins relative to the Q but also the press guides of the press, for which, when applying a standard size of rolled products to the press, it is necessary to center it in relation to the pliers. Dp this before

5 by processing each rolled size, the side rollers 44 and 53 of the feed and receiving roller tables 4 and 9 are moved from drives (not shown) along the axis of the support rollers 39 and 51,

0 so that the cross-section of the treated steel in contact with the side surface of the rollers 44 and 53 was centered with respect to the punch 57 knives. On the receiving rack 1, advanced

5 from under the bridge 5 of the manipulator torus 6, stack a pack of initial blanks with a workshop crane. Then the rack 1 is moved under the overpass 5 and before the gripping of the workpieces it is installed so

0 so that a pack of blanks (with the same length of blanks constituting a pack) or a captured billet (with different lengths of blanks constituting a pack) should be arranged symmetrically with respect to the manipulator along the length 6. Preparations from the pack are individually picked up by the electromagnetic grippers 7 of the manipulator 6. If billet 63 (from shaped or special rolled products) hangs on grippers 7, is incorrectly oriented relative to the position of its laying on live rolls 4, then billet 63 by means of manipulator 6 is placed on tilter 2, which is gray It closes it when the levers 3 are turned so that the profile section wall is horizontal (Fig. 9).

Then the workpiece 63 shift

Q with the manipulator 6 on the support rollers 39 of the feeding roller table 4. The additional rollers 40 in the initial position are located at the level of the support rollers 39 and form together with them

d a common bearing surface that overlaps the annular slots of the rollers 39, so that when the workpiece 63 slips off after detaching it from the grippers 7 of the manipulator 6 along the supporting po5

Cam 39 and additional rollers 40 before contact with the side rollers 44 make it impossible for the profile, especially the small one, to get stuck in the slots of the roller 39 (Figures 9 and 10) Drives of the support and side rollers 39 and 44 of the roller table 4 and the workpiece 63 are fed by the roller table 4 before the position of its rear end in the plane II fixed by the sensor (not shown) (FIG. P of the reference length of the cut part 64, then the drive of the rollers 39 and 44 are turned off, and the workpiece 63 by the carriage 17 is fed to the press 8. Dip this carriage 17 with open jaws 36, located in the initial position behind the plane 1-1, slides over the rear end of the blank 63, stops and seizes it behind the wall lying on the support rollers 39 of the roller table 4 (for corner or channel), or behind the wall they need (for an I-beam or special profile). For gripping the workpiece 63, a pressure is supplied to the piston cavity of the cylinder 33, while the rod 32 with the slider of the cylinder 33 is pressurized, while the rod 32 with the slider 29 is left to the left (FIG. 4), and the case of the cylinder 33 is the slider 30 is mixed right. Sliders 29 and 30 are similar. The hinged axes 28 of the ends of the levers 26 and 27 converge, the levers 26 and 27 rotate around the axis 25, and their second ends, the carrying prisms 36, also begin to approach each other.

The possibility of simultaneous movement of the rod 32 and the cylinder body 38 along the guides 31 provides, with increasing coaxing, the movement of one of the sliders and its stopping, further independent movement of the second slide, which in turn ensures asynchronous mixing;

levers carrying prisms. I

For example, the lever 27 (FIG. P), whose prism 36 rested against the lower surface of the profile wall (channel) being captured, stops, and the second lever 26 continues to rotate until it contacts, its prism 36 with the opposite side of the channel wall. When changing the type or size of the workpiece, for rolling a type of Havel lehr, a corner, a circle, a square or a strip, the final position of the lower jaw gripper 22 will coincide with the level of the support rollers 39 of the roller table 4, and the position of the upper jaw will vary, depending on wall thickness for structural steel or rolled steel itself.

When changing ke type or size of billet for rolling like i-beam

car rack and the like the position of both jaws 36 in the closed state will vary in height relative to the support rollers 39 (Fig. M).

Thus, without changeover and

change the elements of the grip 22 can be carried out reliable grip of various types of shaped and profile rolled products with sizes in the range.

After clamping the workpiece 63 in the carriage 17, the latter from the actuator 19 begins to move along the guides 15, feeding the workpiece 63 along the roller table 4 to the press 8. At the same time, along the movement of the carriage 17, each additional k 40, to which the gripper 22 fits, descends from the cylinder 42 N1 above the level of the slot of the roller 39, passes the levers 27 through the slot of the roller

39. As the remaining additional rollers 40, located between; press 8 and the gripper 22, lifts and overlaps the slits of the rollers 39

lies simultaneously on the rollers 39 and 40, which eliminates the possibility of a curved, long-length workpiece getting into the slots, especially small-sized sections with protruding ribs.

In the case of increased curvature of the workpiece 63 as it moves along the roller table 4, its end will move vertically. In this case, the vertical forces through the levers 26 and 27

will be transferred to the housing 24, which will rotate on the axis 37, compensate for the curvature of the workpiece, and then return to its original position under the action of the springs 38, without transmitting force to the lever 21 and the carriage

17

When moving the carriage 17, it reads the distance traveled by it and determines the length of the workpiece. Preliminary in the systems - CNC, which is equipped with a complex, lay the data on the range and volume of parts and, on the basis of this information, the CNC system gives the results of measuring the length of the workpiece9, 5

KI determines what parts and how much it requires to cut from this blank, based on the conditions for obtaining minimal waste, and gives the command to stop the carriage 17.

After the carriage 17 has stopped, the blank 63 is clamped in the die 57 of the press 8 and a cut occurs. If parts of a small length are cut off, then the receiving roller table 9 is retracted by the cylinder 47 to the rearmost position, the cart 1 1 with the container is fed to the press 8, and the cut piece 64 along the tray 62 falls into the container standing on the cart 11

When cutting lengthy parts, the trolley I1 rolls away to the side and the live rolls 9 are fed by the cylinder 47 to the extreme front position to the press 8, and the front part of its frame 49 enters between the cantilevers; Ravl Nlzimi 53 press 8.

The cut end of the workpiece is fed to the rollers 51. When cutting, the front end of the frame 49 of the roller table 9, turning on the axis 48 of the pnc joint, is lowered, and then the shock absorber 52 returns to its original position. The drive of the rollers 51 and 53 is turned on and the cut piece 64 is brought out by the roller table 9 from the zone of the press 8.

Further, the cylinders 55 (Fig. 8) lower the levers 54 with the rollers 53, which descend below the level of the rollers 51, the component 64 under the action of its own weight through the tray 56 falls into the container 13 for long items.

After cutting the last part in the gripper 22, the waste remains - the end of the original blank 63.

The carriage 17 is fed back, the levers 26 and 27 are opened and the waste falls into the container on the trolley 10. The carriage 17 returns beyond plane I-I and the cycle repeats. In this case, the gripper 22 to the: lever 21 is raised vertically by the cylinder 23. The space above the feed roller 4 is free, and the next billet 63 is laid on the roller 4, before the carriage 17 returns to its original position.

When changing the mix, the stamp change 57 is produced as follows. The roller conveyor 9 is fed by cylinder 47 to press 8. Levers 60 are opened by cylinder 61. After being covered with levers 60 (Fig. 7) of tooth 59 punch 57 cylinder 61 turns levers 60 which are gripping.

1020I)

, the tooth 59 is melted. The roller conveyor 9 is fed to cylinder cylinder 47 in the extreme right position of FIG. 7 by drawing the stamp 57 along the guides 58 from the press 8. The advanced stamp is removed to the magazine 12 by some lifting means, and in its place on the guides 58 set the desired stamp, which also rolls 9 when moving it to the extreme left position is pushed into the press 8.
