Problems solved by technology

Some advanced carcass bonding drums are covered with a layer of rubber on the drum surface to make the drum surface approximate a full circle. There is a problem with this form. The carcass parts and drum tiles are well pasted, while the rubber on the drum surface The carcass parts are not sticky, so it is necessary to add a set of vacuum adsorption discs on the surface of the rubber. This form makes the structure of the carcass fitting drum more complicated, and each adsorption will generate energy waste.
[0003] The carcass fitting drum also needs to be installed on the all-steel radial truck tire secondary method building machine. If the carcass fitting drum on the primary method building machine is directly installed and used, the carcass parts that have been bonded will be damaged during the first stage of the forming machine.

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the body bonding drum of the present invention is described in detail.

[0018] figure 1 It is the structural diagram of the carcass fitting drum. The carcass fitting drum of the present invention is mainly composed of a main shaft 2 and a drum body.

[0019] A left support disc 3 and a right support disc 11 are fixed on the main shaft 2, a hidden cylinder 8 that can slide on the main shaft 2 is arranged in the middle of the two support discs, and a cone 6 is respectively sleeved on the outer edge of the two ends of the hidden cylinder 8. A sealed air chamber is formed between the middle part of the cylinder 8 and the main shaft 2, and the piston 7 is fixed on the main shaft 2 to divide the sealed air chamber into two parts. The main shaft 2 is processed with an air passage hole, and the two air passage holes are respectively connected to the two parts of the sealed air chamber ; One end of the main shaft 2 is equipped w...

Abstract

The invention provides a tyre body fitting drum. The tyre body fitting drum is composed of a main shaft and a drum body, wherein the main shaft is fixedly provided with a left supporting disc and a right supporting disc; a hidden cylinder which can slide on the main shaft is arranged between the two supporting discs, cone-shaped bodies are sleeved on the outer edges of the two ends of the hidden cylinder, and the middle part and the main shaft can form a sealing air chamber; a piston is fixed on the main shaft and can divide the sealing air chamber into two parts, two air channel holes are formed in the main shaft, and the two air channel holes are respectively connected to the two parts of the sealing air chamber; the drum body comprises an angle plate and drum tiles covered on the outer side surface of the angle plate, and the two ends of the angle plate are respectively connected with the left supporting disc and the right supporting disc through radial guide rails so as to enable the angle plate to slide along the radial guide rails; the inner side surface of the angle plate and the cone-shaped bodies are in movable fit through slant guide rails. The tyre body fitting drum provided by the invention has the advantages that the angle plate drives the drum tiles to realize the shrinking movement of the tyre body fitting drum, a gap is not generated among the drum tiles, the rolling effect is good, the structure is simple, the energy utilization rate is high, and the tyre body fitting drum is used in an all steel truck radical tyre secondary method type forming machine.

Description

technical field [0001] The invention belongs to the technical field of tire production machinery, in particular to an all-steel radial tire carcass bonding drum. Background technique [0002] At present, carcass fitting drums are widely used on one-step building machines for all-steel radial truck tires. The drum surface of this drum is a flat plate or the surface is covered with a layer of rubber. The opening or shrinking of the drum tile is realized by the inner mandrel of the main shaft driven by external force, which drives the carcass to fit the pull rod in the drum. After the carcass fitting drum is opened, there is a gap between the drum tiles, and the carcass parts fitted on the carcass fitting drum need to be rolled, and the gap between the drum tiles affects the rolling effect. Some advanced carcass bonding drums are covered with a layer of rubber on the drum surface to make the drum surface approximate a full circle. There is a problem with this form. The carcass...
