Description
Technical Field
The invention relates to the field of automobile tire molding equipment, in particular to a tire bead presetting device used on an all-steel radial tire molding machine.
Background
The tire bead is an important component of the tire and is a stressed part of the tire, and the acting force between the tire and a rim is firstly born by the tire bead and is transmitted to other parts of the tire. The tyre bead is a composite product formed by two parts, the inner side is a steel wire ring formed by winding and weaving a whole steel wire, and the outer side is attached with a triangular rubber. In the tire forming process, the tire bead is conveyed to a preset position by a presetter, then is clamped and conveyed by a pick-up device, and finally is combined with the tire body cord thread component.
The tire bead presetting device of the existing all-steel two-drum forming machine works by adopting a supporting frame group which is driven by a cylinder-connecting rod and is divided into six equal parts in the circumferential direction, and the working part is of a right-angle structure similar to the shape of the reversed U. The left side of the supporting frame is provided with a linear sliding block, and the bottom plate is provided with a guide rail matched with the linear sliding block, is of an umbrella-shaped structure and is radially arranged. When the cylinder rod extends out, the sliding sleeve is driven to be away from the bottom plate of the presetter along the main shaft, and the six support frames can be simultaneously pulled to the main shaft through the connecting rod, so that the radial contraction motion of the support frame group is realized. Conversely, the set of struts will effect an expansion movement, which locks the bead in place.
The pre-setter is installed on the swing arm, and the distance between the support frame and the axis of the pre-setter is adjusted by adjusting the length of the connecting rod of the support frame, so that the position of the circle center of a virtual circle formed on the outer surface of the support frame is adjusted. If the relative position of the tire bead and the main shaft of the forming drum needs to be changed, the coaxiality is in an error range, the lengths of the six connecting rods can only be adjusted in sequence, time is consumed, and the forming drum is quite inconvenient. And because the movable parts are more, the precision of the tire bead presetting position is easy to change, the holding time is short, and frequent calibration is needed.
