Problems solved by technology

[0002] In the tire manufacturing process, the molding machine combines the semi-finished parts according to the process requirements to form the tire embryo. Among them, some semi-finished parts are combined by the molding machine to extrude the parts. After the extruded parts are pasted, they need to be used for pressing. The drum is used to press the combined parts. Poor pressing will cause discounts, bubbles and other hidden dangers.
In order to avoid the problem of poor pressing, the operator manually intervenes in the production process, and manually uses the pressure roller to press around the material. The labor intensity is high, and the uninterrupted production makes the staff very prone to fatigue and reduces work efficiency.

Embodiment 1

[0044] like figure 1 As shown, a method to solve the pressing and discounting of semi-finished parts includes the following steps:

[0045] S1. Determine the structure of the pressure roller used for lamination according to the lamination drop of the semi-finished parts.

[0046] S2. Select a location point and confirm the pressing track.

[0047] S3. After the pressure roller reaches the position point, a pretightening force is applied to the radial and / or axial direction of the pressure roller to improve the pressing effect, and the pressing is performed according to the pressing track and the position point.

[0048] The pressure roller includes a first pressure roller and a second pressure roller, and the width of the first pressure roller is greater than that of the second pressure roller. Considering the lamination efficiency and lamination quality comprehensively, the inventors preferably set the surface width of the first pressure roller to be 80-100 mm, and the surf...

Embodiment 2

[0056] The same part of this embodiment and Embodiment 1 will not be described again, the difference is:

[0057] In order to improve the pressing efficiency, two first pressing rollers are used to press the carcass with a width of 300mm, and the width of the roll surface of the first pressing roller is 100mm.

[0058] The starting point is the middle of the carcass (the middle position of the carcass can be obtained by visual inspection, and the center position of the carcass can also be accurately obtained by measurement, but the error caused by visual inspection and accurate measurement has negligible impact on the quality of product pressing), two The gap between the first pressing rollers is 0. Select the gap between the two first pressure rollers as 150mm as the middle point, and select the gap between the two first pressure rollers as 300mm as the end point, and the pressing track is as follows figure 2 shown.

[0059] The pressure at the starting point is 0Mpa, the ...

Embodiment 3

[0061] The same part of this embodiment and Embodiment 1 will not be described again, the difference is:

[0062] The second pressure roller is used to press the spout, and the width of the surface of the second pressure roller is 10 mm.

[0063] like image 3 As shown, the starting point 1 is the middle position of the spigot, the swing angle is 40°, the width of the semi-finished part between the first middle point 2 and the starting point 1 is 50mm, and the swing angle is 80°, and the second middle point 3 and the first The width of the semi-finished part between the middle point 2 is 50mm, and the swing angle is 120°; the width of the semi-finished part between the third middle point 4 and the starting point 1 is 50mm, and the swing angle is 160°; The width of the intermediate semi-finished parts is 50mm, the swing angle is 240°, and the pressing track is as follows: Figure 4 shown.

[0064] The pressure value from the starting point to the end point is 0.2MPa. After t...

Abstract

The invention relates to a method for solving a folding problem in pressing of a semi-finished part, and belongs to the technical field of tire production. According to the pressing fall of the semi-finished part, a press roll structure used for pressing is determined; a position point is selected, and a pressing track is confirmed; after a press roll reaches the position point, pre-tightening force is applied to the press roll in the radial direction and / or the axial direction, and therefore the pressing effect is improved; pressing is conducted according to the pressing track and the position point; the problems of folding, bubbles and the like of the semi-finished part in the pressing process can be avoided through the method; compared with a traditional auxiliary pressing mode using a hand pressing roller, the method has the advantages that the labor intensity is reduced, and the pressing efficiency and quality are improved; and the product stability is improved.
