The invention relates to a forming machine of an all-steel heavy-duty radial truck tire, in particular to a two-drum forming machine. The invention relates to a two-drum forming machine for the magnetic positioning of a bead, comprising a left bead transferring ring and a right bead transferring ring; the left bead transferring ring and the right bead transferring ring respectively comprise a movable frame, a ring body, a synchronous ring, a bead sucker, an air cylinder and a swing arm, wherein the synchronous ring is movably arranged in a circular groove in the ring body, one end of the swing arm is articulated with the air cylinder, the other end of the swing arm is fixedly connected with the synchronous ring, a plurality of connecting rods are articulated with and arranged at the inner side of the synchronous ring, a plurality of radially arranged chutes are arranged on the synchronous ring, a connecting shaft is arranged in each chute and articulated with a connecting rod, a sliding seat is arranged at the other end of the connecting rod and arranged on a linear guide pair on the synchronous ring, and the bead sucker is arranged on the sliding seat and provided with a magnet. The invention realizes the concentric positioning of the bead on flatness and squareness, avoids deflection and displacement, effectively overcomes defects caused by inaccurate bead positioning, and improves the bead forming quality.
Description
technical field [0001] The invention relates to a molding machine for all-steel load radial tires, in particular to a two-drum molding machine. Background technique [0002] The structure of the bead clamping ring and the bead clamper of the existing all-steel radial truck tire one-step two-drum building machine is as follows: Figure 6 , 7 As shown, the structural principle is as follows: 4 small cylinders are used to respectively drive the clamping and opening of the corresponding claws, and a transmission chain is composed of 1 large cylinder, synchronous toothed belt and rack and pinion pair to realize the linear motion of the cylinder piston rod. It becomes the radial synchronous extension and retraction movement of 4 jaws. After the timing belt bypasses the timing pulley, it is turned up by the tensioner, and the timing belt meshes with the timing pulley of the next bead holder, and the bead holder on the entire ring is connected to a synchronous On the toothed belt,...
