Embodiment Construction
[0011] see figure 1 with figure 2 As shown, the present invention includes a driving cylinder (1), a sliding seat (2), and a plurality of finger pieces (5) symmetrically arranged left and right. The sliding seat (2) can slide axially under the drive of the driving cylinder. The fingers (5) and torsion springs (3) are circumferentially arranged on the sliding seat (2) through the finger mounting seat (4). When the rod of the driving cylinder (1) is retracted, the finger piece (5) is in a retracted state under the action of the finger piece guide wheel (9) installed on the inner circle of the claw seat (8). Steel ring support claws (10) are made up of 10 arc-shaped claw blocks, driven by the support claws to drive the cylinder (6) to drive the drive disc (7) to expand and contract radially to facilitate the installation of the steel ring. During the packing process, the driving cylinder (1) pushes the sliding seat (2), and the finger piece (5) is in an open state under the ac...

The invention relates to a forward packing structure of a steel cord. The structure comprises a frame, finger-type plates, a driving cylinder, a sliding seat, a supporting claw cylinder and a steel ring supporting claw; the upper part of the frame is provided with a crossbeam, the supporting claw cylinder is arranged in the middle position of the frame crossbeam, one end of the crossbeam is installed with a driving disc, the driving disc is provided with a supporting claw base, and a push rod on the supporting claw cylinder and the center of the driving disc are connected; the steel ring supporting claw comprises ten arc shaped claw blocks, and each claw block is installed on the claw base equidistantly; the supporting claw cylinder drives the driving disc to expand and shrink radially in order to facilitate installation of steel rings. The structure has the superiority that the finger-type plates are non-deformable with special structures and performance, the forward packing structure can be specially used for secondary building machines of all-steel radial tires, and can provide forward packing of steel cords with stability and reliability.
Description
technical field [0001] The invention relates to a tire building machine, in particular to a steel cord wrapping structure. Background technique [0002] At present, the wrapping device of the semi-steel secondary forming machine uses finger-shaped pieces to fold up to complete the wrapping of the cord. The finger-shaped pieces are made of spring steel (generally 65Mn), with a thickness of about 1mm, and rely on their elasticity to open naturally. The skeleton of the semi-steel radial tire cord is cord, and the thickness of the rubber material is thin, and the whole is relatively soft. The existing finger-shaped piece can meet the positive wrapping process. The frame of all-steel radial tire cord is steel wire, which has high hardness and elasticity, and the finger-shaped piece made of spring steel has poor rigidity and is easily deformed and damaged, so it cannot be used for steel cord wrapping. Contents of the invention [0003] In order to overcome the limitations of th...
