Description

(54) AUTOMATIC SYSTEM FOR MANUFACTURING FLAT METAL METALS 3 The drive mechanism for opening and closing the strip 21 consists of a lever 23 mounted on the shaft 24, a hinge coupling 25 sliding on the shaft 26 on which the cutting mechanism is mounted. The control mechanism of the stop 22 contains a pneumatic cylinder 27, a rod 28 of the combined lever 29 with stops ZO and 31, an automatic check valve 32 and an adjustable stop 33. The movement of the feed mechanism is sr 34, and with it the operation of all mechanisms is performed by means of a pneumatic cylinder 35 with a rod 36 , a piston 37 and a spring 38. A pneumatic cycling is connected pivotally to a plate 39, with which two guide rods 4O are rigidly connected. The guiding rods 4O, in turn, are rigidly connected to the ridge-shaped plate 19. Me: xx the slot formation consists of racks 41, shaft 42, brackets 43 and n-set probes 44. A mechanism to prevent the grid web from shifting randomly, ensuring uniform pressing of the guide bar to The net consists of a rubberized drum 4S, a brake wheel 46, a band brake 47, a pressure shaft with concentric streams 48, and levers with sockets 49 for the selection of pressing force. When working on 4 | or yuvannye rods and singing welded seki, they are positioned along the rubberized drum, and the rubber surface (even with light pressure), try to fill the grid slots, securely holding the web of the grid in a single position. From the electric motor 7, through the clutch 8, the coupling 15 is transmitted to the plate chain 2. Through the entire length of the chain 2, at certain intervals, are mounted hg 5, representing cams with levers and rollers 6 on them. F olices roll along the walls of the 5 O bed and, the raid on the plates 51, press the grippers 5, press them to grip the transverse wire, and the runaway from the plates 51, the grips 5 are removed and tied. The extractable wire enters through wiring 52 into wiring 53 and, reaching contact 54, clamps it and feeds a pulse to the coil of the solenoid 55 after which the -th (1de; solenoid pin switches off the spacer Plate 56, and the spring 57 when the Moiiiif spring 58 disconnects gear Myijiiy 8, and feeding npoBOjjoKU kinovno ((rec.111111 shetts. When disconnecting the gear Myil) 8, a signal is given to compress compressor101-0: air in the pneumatic cylinder 35 Ponmotsilipdr 35 acts on the platform 39 and has corrected sources 6 of these rods mech.nizm filing produces the following work : a) by means of the shaft 26, a section of the rod 34 of profiled lead filed in the wiring 53 is produced; b) a comb-shaped plate 19, moving in the direction indicated by the arrow B, the shaft 26 mounted under it and the hinged coupling 25 acts on the lever 23 and turning the shaft 24 raises the bar 21 of the wiring 53 for free movement of the rod 34 under the electrodes; II c) simultaneously with the raising of the bar 2.1 and cutting. the rod clamping mechanism is activated; the spring in the cavity of the pneumatic cylinder 27, pressing on the piston, draws into itself a rod 2B connected to the lever 29, and this lever rotates the shaft 26. The shaft, turning, with the stops 22 mounted on it, presses the rod 34 to the profile ruler 2O and in the enclosed state, the rod leads to the probes 44. After that, clamped the rod, the web of welded mesh is squeezed one step, and the rod 34 stands in the center of the electrodes 13 and 16. At the end of the stroke, the plate 19 feeds a pulse to the solenoid coil 59. The coil core holds the with him plate 6O, and lever g 61 using a spring includes a drum 62, which is paired with drum 03. Pa contacts 63 and a figurine plate 64 are mounted on drum 63. A drum core 63 is fed under electrodes. The latter, turning, sends a signal for air inlet to the pneumatic cylinder 10 and compresses the electrode wire crossing points. After a complete build-up of pressure in the 1O cylinders, a powerful impulse is produced on welding Tpciiti i | H) (JMa.tor 65 and contact curing of the compressed wire crossing points takes place. After welding, compression of the electrodes continues for a while. 1.; pressure drop in the pneumatic cylinder lU by means of the spring 15, the electrodes 13 are iodine-free, releasing the profile ruler 2O. Then the feed mechanism of the rod B03ii jiiina returns to its original position. At this time, the cycle of feeding and welding of one wire rod ends . Returning to the starting position, the feed mechanism of the negative rod pushes a pulse to the solenoid P (), which includes mu ((| that 8, and the start of the next feed of the fi rg) (t, c.
