Description
Technical Field
The invention relates to the technical field of tire forming, in particular to a belt drum component of an agricultural radial tire forming machine and a method for laminating a belt layer by using the component.
Background
The agricultural tire is mainly installed on tractors, combine harvesters and agricultural implement vehicles, a green tire of the agricultural tire is composed of a tire tread and a tire body, the tire tread generally comprises a belt ply, a cap ply and a tire tread layer, and the tire body generally comprises an inner liner, a tire side layer, a tire bead and a cord fabric layer. Compared with tires of transport vehicles, the agricultural tires are characterized by intermittent operation and long service life, so that agricultural tire orders are not large-batch orders for tire manufacturers, and the types of agricultural vehicles are numerous, which requires the tire manufacturers to frequently change the specifications of production equipment when producing the agricultural tires.
The belt drum is a device for belt layer fitting, consists of a plurality of drum plates in the circumferential direction and has the functions of rotation and expansion. The rotating function is used for attaching the belt ply rubber material along the circumferential direction of the drum in the tire manufacturing process; the expansion and contraction function is to adjust the diameter of the belt drum by controlling the expansion and contraction of the drum plate, thereby realizing the purpose that the same belt drum can produce tires with various specifications and sizes. When the tire tread is formed, a belt ply is firstly arranged on the circumferential surface of a belt drum, a crown strip ply is arranged on the circumferential surface of the belt ply of the belt drum, and finally the tire is arranged on the circumferential surface of the crown strip ply of the belt drum.
The belt drum chassis is a device for providing support, movement and power for the belt drum.
The key point and difficulty of the design of the belt drum and the machine case of the belt drum are that the expansion and contraction and the stability of the diameter of the belt drum are accurately controlled, the diameter of the belt drum directly influences the diameter of a belt layer which is attached, the diameter of the belt layer directly relates to the specification and the size of a finished tire, and once the actual diameter of the belt drum is inconsistent with the required diameter when a tire factory produces a tire with a certain specification, mass production quality accidents can be caused.
Aiming at the problem, one existing solution is that when a belt drum is designed, an air cylinder is positioned in the drum, the air source power of the air cylinder is connected into the drum through a rotary seal or a rotary joint, the air cylinder is adopted to drive the expansion and contraction of the diameter of the belt drum, a mechanical limiting device is arranged at the diameter position of a corresponding specification in the expansion and contraction range of the diameter of the belt drum, and the expansion and contraction diameter of the belt drum is adjusted by manually adjusting the position of a limiting screw; the rotation of the belt drum is controlled by a servo motor of the belt drum chassis. This solution is time consuming, laborious when switching belt drum diameters and will lead to product quality accidents in case of operator adjustment errors. In addition, the sealing ring inside the cylinder is worn and torn after the belt drum expansion and contraction cylinder is used for a long time, the replacement is very inconvenient, meanwhile, the air source power of the cylinder needs to be connected into the drum through a rotary seal or a rotary joint because the cylinder is positioned in the drum, and the seal failure can also occur after the rotary seal or the rotary joint is used for a period of time.
In addition, there is an existing solution, for example chinese utility model patent publication No. CN211730346U, discloses a belted drum device, wear to be equipped with the push rod in the cavity drum axle, the push rod drives frustum axial displacement through the bearing subassembly, through radial clearance fit between push rod and the bearing subassembly, avoids belted drum to rotate the harm of in-process to the push rod, the actuating mechanism of push rod is the electric jar, and the push rod is the output of electric jar promptly. For example, chinese utility model patent publication No. CN211737922U discloses a belted drum driving device, which adopts the electric cylinder output shaft to move along the axial direction, drives the wedge frame to move axially through the connecting rod to complete the first expansion of the belted drum, and the gas enters the second air passage of the conversion head through the first air passage of the outer shaft, and then is supplied to the belted drum through the air cock and the air pipe, so that the belted drum can be pneumatically driven to realize the second expansion. In the above solution, only the electric cylinder output shaft is used, or the electric cylinder output shaft is combined with the gas drive to control the belt bundle drum to expand, only fixed specifications can be produced, and when the diameter specification of the belt bundle drum needs to be changed, the expansion and contraction diameter of the belt bundle drum still needs to be adjusted by manually adjusting the position of the limiting device.
How to overcome the deficiencies of the prior art schemes, improve the specification switching efficiency of the belt bundle drum, reduce the participation of human factors, improve the precision of the equipment and prolong the service life of the equipment by accurately controlling the expansion and contraction of the belt bundle drum, and become the subject to be solved urgently in the technical field.
