Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
As shown in the figure: main shaft 1 the middle part the tapered cylinder 4 of outer surface is installed, and inwall is the slide block 5 of Wedge type, the Wedge type inner surface of the taper surface of cylinder 4 and slide block 5 is slidingly matched, the inwall of cylinder 4 cooperates with piston 3 on being fixedly installed in main shaft 1, the outer wall of slide block 5 is connected with rebound 6, cushion block 7 is installed on rebound 6, cushion block 7 is fixedlyed connected for bulging watt 8 with liner, outer wall at liner drum watts 8 has groove, extension spring 9 is installed in the groove, at liner drum watt 8 outer installation waistbands 10, bulging watt 11 and drum face rubber ring 12, guide pillar 13 is installed at two ends at rebound 6, a left side is installed respectively on the main shaft 1 of cylinder 4 both sides, right guiding attic base 14,15, the other end of guide pillar 13 is slidingly matched with the interior pilot hole of attic base that leads.When the cylinder 4 of taper moves right, under the driving of the conical surface, drum watts 11 is the drum type attitude that rises, and stretches at cord, the wire loop left and right sides, the back push rod 22 that puts in place successively releases, and receives cord, turns over bag, roll extrusion, finishes tyre carcass forming; When cylinder 4 moved to left, under the contraction of extension spring 9 and drum face rubber ring 12, drum watts 11 was the drum type attitude that contracts, and unloads the tyre carcase space and goes up the cord technological requirement to satisfy.When needs are adjusted the work external diameter of assembly drum, change the cushion block 7 of different-thickness and can realize.
During work, the air flue 26 of compressed air in main shaft 1 enters the rightward space of taper cylinder 4 and piston 3, taper cylinder 4 is moved right, slide block 5 radially outward moves in the driving lower edge of the conical surface, drive liner drum watts 8, drum watts 11 and guide pillar 13 etc. and expand outwardly together, make drum watts 11 be the drum type attitude that rises, when expansion is mobile, lead by the pilot hole on guide pillar 13 and the guiding attic base 14,15, guarantee that liner drum watt 8 grades radially outwards move; Even with air flue 26 to the left and right inboard air feed that turns over bag cylinder 17,19 and its piston 18, the left and right bag cylinder 17 that turns over is successively moved to the centre, promote strut 20, connecting rod 21, push rod 22, extension spring 23 and roller 24 actions, roller 24 on the push rod 22 is rolled to the centre on drum face rubber ring 12, cord is turned over bag, roll extrusion, finish tyre carcass forming; Otherwise compressed air enters the left side of taper cylinder 4 and piston 3, and taper cylinder 4 moves to left, under the contraction of extension spring 9 and drum face rubber ring 12, bulging watt 8 of liner and slide block 5 inwardly shrink, and being the drum that contracts and unloading the tire operating mode, are at this moment led by guide pillar 13 and pilot hole equally; Immediately to the outside air feed that turns over bag cylinder 17,19 and its piston 18, the left and right bag cylinder 17,19 that turns over is outwards moved, drive strut 20, connecting rod 21, push rod 22, extension spring 23 and roller 24 actions, the roller 24 on the push rod 22 is being rolled on bulging watt 11 to both sides on the bulging face rubber ring 12.Wherein, roller 24 is under the effect of its extension spring 23, and sliding in the surface that is close to bulging face rubber ring 12 and drum watts 11 all the time, finishes specified action.
Be the boundary with the spindle centerline among Fig. 1, be respectively two kinds of duties.Top is to turn over bag cylinder 17,19 to the centre is drawn close, taper cylinder 4 moves right state; The bottom is then for turning over the state that bag gas 17,19 cylinders are moved to the left to two side shiftings, taper cylinder 4.
