Abstract
The invention relates to a mechanical drum for reverse rolling on a one-step forming machine of special equipment for all-steel radial truck tires. The main shaft device mainly comprises a main shaft device and a left side drum and a right side drum, wherein each side drum comprises a group of anti-wrapping rods which are uniformly distributed in the radial direction, the front end of each anti-wrapping rod is provided with a large roller and a small roller in a staggered mode, the large roller and the small roller can be arranged on an eccentric Y-shaped wheel seat, and the Y-shaped wheel seat is hinged with the front end of the anti-wrapping rod. Because the anti-package pole adopts two roller structures, and big gyro wheel and the crisscross setting of truckle, the truckle will be rolled in once more after big gyro wheel roll-in, and the side wall of messenger's child embryo is more abundant in the roll-in when the anti-package, and simultaneously, the truckle also will supply the roll-in to the roll-in blind area of big gyro wheel, eliminates or reduces the roll-in blind area, makes the child embryo impression of processing shallow, does not remain the bubble to shaping quality has been improved.
Description
Technical field:
The present invention relates to a kind of rubber tyre machinery, especially a kind of machinery drum that is used for the anti-package roll extrusion on the full steel wire meridian high-capacity tyre special equipment once time forming machine.
Background technology:
Continuous growth along with the domestic automobile sales volume, particularly the demand in all-steel radial tyre market is also increasing, therefore also more and more higher for the specification requirement of tire manufacturing, the domestic employed assembly drum of meridian high-capacity tyre once time forming machine mostly is inflatable capsule reverse wrap molding drum, it is in the forming process of tire, need make its expansion to the capsule inflation, finish the anti-package and the compacting at position, sidewall, then the gas in the capsule is discharged, make its reinstatement, carry out operation next time again, because capsule inflation anti-package belongs to the elasticity compacting, can not guarantee uniformity, the Forming Quality of green tyres is brought de-stabilising effect.In order to overcome the weak point of inflatable capsule reverse wrap molding drum, people's design provides anti-package roll extrusion machinery drum.
Existing anti-package roll extrusion machinery drum mainly is made of main shaft and two side drums being symmetrical set on main shaft, each side drum is mainly by the counter-wrapping rod assembly, fetus fastener and counter-wrapping rod drive cylinder and constitute, the counter-wrapping rod assembly then is made of one group of identical counter-wrapping rod of structure, and the front end of every counter-wrapping rod is only installed a rolling wheel, it is single pole single-wheel structure, because rolling wheel must be connected the front end of counter-wrapping rod by wheel seat, therefore, between rolling wheel and rolling wheel, certainly lead to the gap, especially in the rolling wheel roll extrusion during to the fetus exterior lateral area, gap between rolling wheel and the rolling wheel is bigger, there is the blind area in roll extrusion to fetus, will produce quality problems such as tangible roll extrusion impression and the residual bubble of fetus.
Summary of the invention:
The objective of the invention is to overcome the weak point that existing anti-package roll extrusion machinery rouses, provide a kind of and can eliminate or reduce the roll extrusion blind area, thereby eliminate or minimizing roll extrusion impression and residual bubble, improve the anti-package roll extrusion machinery drum of Forming Quality.
The present invention, comprise main shaft device and two side drums that on main shaft, are symmetrical set, main shaft device comprises hollow spindle, ring flange and end cap, in hollow spindle inside, be provided with left and right sides helical screw transmission, left-right symmetry is provided with two nut sleeve on the helical screw of the left and right sides, every nut sleeve passes chute on the hollow spindle by pin key and corresponding side drum connects, axle sleeve and the one group of radially equally distributed counter-wrapping rod that is sleeved on the hollow spindle drawn together in each side bulge, waist at counter-wrapping rod, at least be provided with an elastic rubber ring, the elastic rubber ring snare is on all counter-wrapping rods of homonymy, axle sleeve links to each other with nut sleeve by pin key, front portion at axle sleeve, be provided with the fetus fastener, rear portion at axle sleeve, be provided with counter-wrapping rod and drive cylinder, described driving cylinder is by fixed piston, active cylinder block is formed with drive end bearing bracket that is connected the active cylinder block two ends and rear end cap, fixed piston is fixedly connected on the axle sleeve, active cylinder block cooperates with fixed piston, the root of described counter-wrapping rod is hinged on the machinery adjacent with rear end cap and refers on the outer press ring, and the front end of every counter-wrapping rod is provided with a big roller and a trundle, and described big roller and trundle are crisscross arranged.
The present invention, described big roller and trundle can be installed on monaural off-centre " Y " the shape wheel seat, and the front end of " Y " shape wheel seat and counter-wrapping rod is articulated and connected.
The present invention, fetus fastener on described each side drum comprises a positioning cylinder, one group of radially equally distributed secter pat and a guide plate, positioning cylinder is made of cylinder body and piston, every secter pat is connected with piston by corresponding connecting rod, on secter pat, be provided with radial groove, groove is provided with sealed rubber ring, the inboard of sealed rubber ring is provided with the elasticity of extension edge, the elasticity of extension edge is stretched casing wall by the court of a feudal ruler of pressure ring and positioning cylinder body and is tightly connected, on sealed rubber ring, be provided with the curved grooves of wire loop location.
The present invention can be provided with the counter-wrapping rod position-arresting disk in the rear end of each axle sleeve.
Good effect of the present invention is: after fetus is finished typing, the sidewall anti-package roll-in of fetus is finished by two groups of rollers of counter-wrapping rod front end, because counter-wrapping rod adopts big roller and trundle two-wheel structure, and big roller and trundle are crisscross arranged, the roll-in effect of big roller is same as the prior art, trundle is owing to be arranged on the below of big roller and between two big rollers, trundle will roll-in once more after the big roller roll-in, make sidewall roll-in when anti-package of fetus more abundant, simultaneously, trundle also will replenish roll-in to the roll-in blind area of big roller, eliminate or minimizing roll-in blind area, make processed fetus impression shallow, not residual bubble, thereby improved Forming Quality, and reduced labor intensity of operating personnel.In addition, the sealed rubber ring in the fetus fastener is provided with curved grooves, and curved grooves has limited the free degree of fetus wire loop, makes it when operations for forming, and wire loop is unshift, guarantees Forming Quality.
