SU84635A1 - Rubber Tube Making Machine - Google Patents

Description

The known machines for the manufacture of rubber rubber pipes by hand are low-yielded. The partial mechanization of this process (knitting) is also imperfect, since it only takes the final part of the process of manufacturing the tubing and also does not relieve the worker from having to do certain work manually.

Onysyvaemya mechanizes the manufacture of agricultural pipes and has the peculiarity that it is wicked in the form of a swinging arc in the horizontal plane of the trolley, above the platform of which the frame is hung at the hinge of the irizhna frame, nestus, and in its bearings the mandrel, the turnable axis of its axis the edges of the tube blank and the ejector of the finished tubes moving back and forth along the mandrel.

Figure 1 schematically shows a vertical section of the machine: H0 A-A on the fng. 2; in fig. 2-section io EB in FIG. one; in fig. 3-across Hbiii section BUT B-B in FIG. one; in fig. 4-horizontal section of G-d on f1: g. ; on fng. 5th part. but arrow A, side view.

The MaHJHi # i bed is a table with an upper flat plate in the form of a part of a ring. An irivod is mounted on the frame attached to the frame; 1e. It transmits motion from the electric motor U to the trolley and consists of gearbox 2, bevel gears 3 and 4, crank 6, rocker stone 7 and drove 5, pivoting around the axis 44 and connected to the cart.

On the frame bracket 26, a naft is mounted with a gear 28 and a large block 29 mounted on it, as well as a crown 31, on which

tray and rolls down the TJ counterfeit box. The extreme left position of the ejector corresponds to the extreme position of the trolley located in this moment on the opposite working part of the hundred

Nina.

During the reverse movement of the trolley in the direction of the worker, the cycle proceeds in the reverse order: the ejector moves to the right, roller 12 is in the nerve head, in which it props up the end of the doria with the sleeve, the mandrel 14 begins to rotate in the opposite direction, since . however, the holder begins to rotate and, thus, all working parts of the maschine return to their original position.

Subject and purpose of

Claims (2)

1. A machine for the manufacture of rubber pipes with the use of a dorn, from one to another with the fact that it is made in the form of a horizontal trolley swinging along the iB arc along the base plate above the base of the machine Izhna frame, not sui.1a, in its iodn ipniki, is an enemy of Dori, a Novurot holder of its own around the axis of the tube blank and a reciprocating-moving ejector of the finished tubes. 2. Forming a machine according to claim 1, characterized in that at the periphery the table is equipped with sector-mounted toothed racks of various lengths used for driving the mutually coordinated movement of the mandrel and the holder by means of mounted on crown | e machines of gear teeth and pusher by means of giesters and a system of blocks with cables. STI bogies so (Fig. 4) that its edge at 10-15 mm stands for the front edge of this plane. When the trolley moves in the direction away from the working top of the trolley, its bevel deflects the levers 35 in position, and the dotted line in FIG. 4, so that a gap of 3-4 mm is obtained between the i.e. ends and the surface of the mandrel 14, into which the projecting edge of the workpiece freely enters. At this moment, the first tooth of the lath 25 engages with the sows 24, as a result of which the darp l4 clashes, so that in any vertical section, there is a superperiodicle of the spindle axis, and the movement of the points of the mandrel surface and the plane of the carriage, as well as the equality of their speeds, as if the mandrel rolls along the cart without sliding. Consequently, during the filling between them, the workpiece does not experience the action of the tipping force. The next moment, the nerve tooth of the rail 20 engages with the bristles 19, as a result of which the holder begins to rotate in the same direction and with the same angular velocity as the mandrel. In this case, the carrier levers 35 no longer come into contact with the carriage, and the springs 37 rotate them around the roller 38 until the ends of the arms press the workpiece to the surface of the mandrel. In this way, when the blanks are pulled up onto the mandrel, to the position shown by flat black lines, the levers 35 hold it all the time. When this position is reached, the holder ceases to rotate, so that at this moment the rail 20 disengages from the gear 19, and the abrasive console-panel 36 abuts against the support 46 of the frame 13 with its sprout. Lever 5.9 roller 38, abutted against screw 41, somewhat shakes the roller 38, which, acting with scallops in the letter on the adjustable screw 40, deflects the levers so that their balls 3-4 mm away from the surface of the mandrel 14. At the same time, the levers 35 NO in one place do not touch below them are the planes. stitch 15. The counterweight 43 reliably fixes the holder, since the mandrel 14 continues to rotate and the carriage 15 moves, and the frame with the mandrel presses the workpiece to the carriage. The workpiece continues to be wrapped around the mandrel 14, the passage freely past the ends of the levers 35. and forms the second layer. The second layer of the workpiece under pressure of the mandrel 14 is glued to the first. With continued movement of the carriage 15, the workpiece is completely screwed onto the mandrel, the closing strip is rolled and glued, and the further auxiliary rolling of the sealed tube continues. Rolling continues until it leaves the gear 24 of the rails 25. At the next moment, the ball roller lever .9, still rolling along the arc-shaped groove of the link 8, the radius of which is described from a point lying on the axis of rotation, moves to the crankshaft section of the slot of the link, due to the chip, the lever 9 is deflected, acting through the pull 10 on the lever 7 /, which is turned to the right. Due to this, a space of 10-15 mm is formed between the roller 12 and the mandrel. The ball roller gets into the next, concentric to the first, arcuate groove of the link 8 and the position of the lever // until the end of the trolley travel remains unchanged. At this moment, the rake 27 engages with the bristles 28, and the wheel 29 tons is not a tr-axle. The latter moves the sleeve attached to it, and the latter in turn moves the ejector 45, which lifts the tube from the stationary still at that time. The tube falls on the slope 84635 Ordeactor P. B.
