Problems solved by technology

After the unqualified turn-up capsule is inflated, because of its uneven shape, it is easy to cause the tire carcass cord fabric to not be evenly turned up, so that some parts of the turned-up part are deformed due to excessive pressure, and some parts are too small to have pressure. Phenomena such as tightness, leading to problems such as tire scrapping or refurbishment

Embodiment 1

[0062] This embodiment provides a reverse-wrapped capsule pressure detection device, such as Figure 1 to Figure 14 As shown, the pressure uniformity detection device for the reversed capsule includes a frame 1 , a support cylinder 2 , a fixed component 3 for the reversed capsule, a pressure detection component 5 and a control unit 6 .

[0063] The support cylinder 2 is used to install the pressure detection assembly 5 and the fixed turn-up capsule fixing assembly 3. The turn-up capsule fixing assembly 3 is used to install the tested turn-up capsule. The compression degree of the body cord is displayed by the pressure value, and the control part 6 is used to control the action of the pressing plate assembly 4 and the pressure detection assembly 5, and detect the pressure on the pressure assembly, and display the detection result.

[0064] The pressure detection assembly 5 includes an outer large air bag 51 and a plurality of small air bags 52 arranged in the large air bag 51. ...

Embodiment 2

[0074] In addition to the content of the previous embodiment, this embodiment also provides a pressure uniformity detection device for an inflated turn-up capsule, such as Figure 15 As shown, the pressing plate assembly 4 is used to simulate the pushing effect of the finger plate on the molding machine on the turning-up capsule when the turning-up capsule is working. The pressing plate assembly 4 includes a cylinder 41 and a pressing plate 42. The pressing plate 42 includes a horizontal plate 421, a sleeve 422, The vertical plate 424 and the pressure ring 423, the cylinder 41 is installed above the beam 13, and its telescopic column passes through the beam 13 to connect with the pressure plate 42 below, the four corners of the horizontal plate 421 are provided with mounting holes, the bottom of the mounting hole is connected with the sleeve 422, and the pressure plate 42 is installed on the guide rod 14 through the sleeve 422 and can move up and down. The center of the horizon...

Abstract

The invention relates to the technical field of tire forming, in particular to a turn-up capsule pressure uniformity detection device and method. The turn-up capsule pressure uniformity detection device comprises a frame, a support cylinder, a turn-up capsule fixing assembly, a pressing plate assembly, a pressure detection assembly and a control part. The pressure detection assembly further comprises a large air bag on the outer layer and a plurality of small air bags arranged in the large air bag, and the small air bags are connected with valves and pressure sensors through external pipelines. By means of the device, whether a turn-up capsule is qualified or not can be detected, a defect area on an unqualified turn-up capsule can be found out, therefore, process personnel can be helped todiscover defects on a production process or equipment, an effect of defect early warning is achieved, and greater loss is avoided.

Description

technical field [0001] The invention relates to the technical field of tire building, in particular to a pressure uniformity detection device and detection method for a turn-up capsule. Background technique [0002] At present, the building drums used in radial tire building machines are mainly divided into two types: mechanical building drums and capsule building drums. The difference lies in the way the sidewall expands when the tire sidewall is turned up. The circumferential stretch of the sidewall of the bladder forming drum is more uniform than that of the mechanical forming drum. Therefore, most manufacturers use the bladder forming drum to manufacture the outer tire of the tire. The turn-up capsule used on the capsule forming drum can expand evenly under a certain air pressure, and the push plate of the forming machine will evenly turn up and compact the tire carcass cord cloth installed on the capsule forming drum through the capsule, so that the tire tire There is ...
