Description

The invention relates to the field of cold working pressure and can be used for processing strip material.

The purpose of the invention is to reduce the size and increase the reliability of the complex.

FIG. 1 shows an automated complex for processing strip material; in fig. 2 is a view A of FIG. one; in fig. 3 - section B — B in FIG. one; in fig. 4 — section B — B in FIG. 2; in fig. 5 is a view of FIG. four; in fig. 6 - section D - D in FIG. one; in fig. 7 is a view E of FIG. 6; in fig. 8 — node I in FIG. 1, the cut.

The automated complex contains a press 1, a conveyor 2 with a device 3 for separating the strips (blanks) 4 from the foot 5 and the mechanism 6 for laying the strips 4 on the rollers 7 of the conveyor roll 2. In the working area of the press 1 a stamp 8 is installed, and the press feed is mounted on the base of press 1 device 9.

In the press 1, a rejection mechanism 10 is installed (or made integral with it) and a waste treatment device is installed, comprising a waste cutting 11 mechanism, designed as a press and knife 13 mounted on a slider 12, and a device 14 mounted on a substamp plate 15 press 1.

The roller conveyor 2 comprises a frame 16 connected at one end with a press 1, and its other end is mounted on a support 17 having rollers 18. In the frame 16, shafts 19 are installed, carrying rollers 7 with annular projections 20. On support 17 an electric motor 21 is installed, resulting in movement using a chain drive (not shown) shafts 19. To adjust the position of the end of the frame 16 in height relative to the support 17, the frame contains screws 22. A device for separation. strips (blanks) 4 from the foot 5 contains a U-shaped frame 23 installed with the possibility of turning on the axes 24 fixed in the trunnions of the frame 16 of the roller table 2. Between the guides 25 to accommodate the strip 4 attached to the frame 23 and the guides 26 for moving the foot 5, a clearance is established sufficient to allow only one lane to exit. At the base of the frame 23, in the plane of separation from the foot 5 of the strip 4, the driving disks 27 are mounted on the shafts 28 with the pushers 29 interacting with the strip 4.

The mechanism 6 laying pole 4 on the carrier rollers 7 of the roller table 2 is made in the form of a pair of bars 30, arranged parallel to the longitudinal axes of the carrier rollers 7. One end of each bar 30 is connected via a bar 31 to a rod 32 of the power cylinder 33 fixed on the frame 16 of the roller table 2, and the other end through the earring 34 is connected to the frame 16. With its middle part, the bar 30 is pivotally connected to the height-adjustable guide columns 35. For pressing the strip blank 4 to the bearing rollers 7, the clamp 36 is mounted on the frame 16 of the roller table 2.

The roller feeder 9 for feeding the strip 4 into the stamp 8 of the press 1 is made in the form of rollers 38 and 39 mounted in the housing 37 fixed on the press stand 1, the gap between which is adjusted by means of threaded bushings screwed into the power cylinders (not shown) housing 37 with the ability to interact with their pistons. In the working area of the press, before the die 8, rolls spring-loaded lever 40 are mounted on the roller 8 and the carrier roller 41. A lever 42 is fixed on the lever 40 and communicates with the limit switch 43, which is electrically connected to the counter of the number of press strokes 1 installed separately (not shown). Under the stamp 8 of the press 1 for separating the stem of the products being processed (for example, unmeasured branches), a rejection mechanism 10 is placed, comprising a hollow body 44 in which a partition 45 is installed dividing the body 44 into two sleeves 46 and 47. A damper is fixed on the axis 48 in the body 44 49, made in the form of a wedge strip. The axis 48 of the lever 50, mounted on one of its ends, is connected with the rod 51 of the power cylinder 52, mounted on the table of the press 1 and connected with pipelines to the distribution mechanism 53.

A device for processing waste coming out of the stamp 8 in the form of a perforated strip, contains a knife 13 fixed on the slider 12 after the punch 54, cutting the products from the strip 4, in the upper plate 55 of the stamp 8 is formed an opening 56 into which the knife can enter 13. In the lower base of the knife 13, perpendicular to its cutting edge, windows 57 are made, through which the hook gripping bodies having thrust 58, equipped with hooks, are passed. Traction 58, installed with the possibility of free reciprocating movement, is pivotally connected with intermediate lever links 59, rigidly fixed on shaft 60. Shaft 60 is mounted in rolling bearings in bearings 61 on sub-die plate 15. With slide 12 of press 1, shaft 60 is connected through a damping the device 62, the adjusting screw with the nut 63 and the lever 64 rigidly fixed on its end. The position 65 designates the tray along which the cut waste 11 is removed into the container, the position 66 denotes the conveyor for moving the blanks cut to the hole. to their off-gage balances.

Automated complex works as follows.

for separation of strip blanks from the foot. The frame 23 installed on the axes 24, fixed in the trunnions of the frame 16 of the roller table 2, is given the optimal angle of inclination to the roller table 2 based on the condition of ensuring the movement of the foot 5 and the minimum effort to separate the strip 4 from it. Pressing the "Start" button on the control panel drives the disks 27 mounted at the base of the frame 23 on the low-speed shafts 28 in the plane of the detachable strip 4. The disks 27, turning, turn the arc-shaped profiles of the pushers 29 to the lower foot strip of the workpieces 5, shift it and reset on the strips 30 of the mechanism for laying the strips on the rollers 7 of the roller table 2. The rods 32 of the power cylinders 3 are pulled out at the moment of separation of the strip 4 from the foot 5 and hold the strips 30 at an angle to the axes of the carrier rollers 7 of the roller table 2. The strip 4 after separation from the foot lies on the strips 30, resting on one of the annular projections 20 of the rollers 7, and is oriented relative to the working zone of the press 1. The power cylinders 33 operate, the rods 32 lower the strips 30, and with them the strip 4, which fits on the rollers 7 of the roll table 2. Include the electric motor 21 of the roller table 2, which drives the shafts 19 with the rollers 7 by means of a chain transmission. The strip 4 moves to the roller feed mounted on the press rack

1. To ensure more reliable adhesion of the rollers 7 to the transported billet, the clamp 36 presses it during movement to the rollers 7. The end of the strip 4 is inserted into the gap between the separated rollers 38 and 39 of the roller feed 9 into the die 8 until it stops. After filling the feed material in the rolls 38 and 39, the latter are closed under the action of power cylinders (not shown) and, upon command while the press is running, turn lane 4 to the feed step. When leaving the rolls 38 and 39 of the roller feed 9, the strip 4 in the working area of the press interacts with the roller 41 mounted on the swinging spring-loaded lever 40. The latter rises and acts by the bar 42 on the limit switch 43. The end switch is activated and gives a signal to turn on the stroke counter (not shown) and turning off the roller table 2. After a certain number of strokes of the slider 12 of the press 1, after processing the strip 4, one of the counters of the number of strokes sends a signal to turn on the device 3 to separate the strips from the foot of the mechanism 6 instructors adki strips on the roller table and the roller table 2 itself, which is fed next band to the rollers' roller 38 and the feed 39

9. After the specified number of working strokes of the press ram has been completed, another stroke number counter signals the distribution mechanism 53 of the device 10 for rejecting products for supplying the working medium to the power cylinder 52 and for switching on the third counter of the press strokes. The rod 51, moving, turns through the lever 50 and the axis 48 of the valve 49, which overlaps the sleeve 47. The oversized piece cut from the unmeasured end of the strip 4 is removed from the die area of the press along the sleeve 46. Full-sized products cut from the strip are removed from the die area along the sleeve 47 after the flap 49 overlaps the sleeve 46. Along with cutting punches 54 products from the strip 4, cutting of the waste (perforated strip 4) and its removal from the stamp 8 on the tray 65 into the container is performed. For each working stroke of the slider 12, the knife 13 fixed on it, cuts the waste in the area of jumpers into measuring strips, and the thrust 58 with hooks simultaneously with the movement of the knife 13 down through the opening 56 in the top plate of the stamp and sharp material of the waste make free movement through the windows 57 at the base of the knife 13 in the direction to the central axis of the stamp and in the final position of the stroke, hook the strip 4 by the holes left after cutting. During the course of the slider 12 upward, the lever 64, attached to the end of the shaft 60, under the action of the pulling force transmitted by the slider 12 through the damping device 62 and the screw with the nut 63, turns the shaft 60 in the supports 61, and the intermediate link links 59 displace the thrust 58 with hooks into the extreme right (Fig. 4) position, thereby setting the strip 4 in the zone of jumpers under the knife 13. During the slide 12 down, the punches 54 cut, the knife 13 cuts off the end of the waste, which is removed to the container 65 and the hooks 58 with hooks go through the window 57 at the base of the knife 13 in the stamp and hook E grasp strip 4. During upward withdrawal of the slide treatment cycle is repeated,

those. the knife goes up, and the thrust 58 tightens the strip 4 under the knife 13. After the specified number of working strokes has been completed, the slider 12 triggers a stroke counter (not shown), the rejection mechanism 10 closes the flap 49 sleeve 47 and removes the oversized parts “to failure” strip 4, under the stamp 8 on the conveyor 66, from where they are discharged into the container. The end of lane 4 is removed from the stamp, the stroke counter is triggered, and the cycle repeats. A device for separating the strip from the foot 3 and the mechanism for laying the strip on the rollers of the roller table 2 are turned on, after which the strip is fed to the rollers 38 and 39 of the roller feed, the slider 12 together with the strip movement makes a specified number of strokes, determined by the stroke counter and the strip length, the products are cut and the remaining waste is cut into pieces in die 8 and discarded into containers.
