Description

Technical Field

[0001] The utility model relates to the technical field of tire forming equipment, and particularly relates to a disc device for a semi-steel tire forming machine. Background Art

[0002] A tire is a component of an automobile that directly contacts the ground, and the quality of its performance directly affects the safety of the automobile. Forming is a very important process in tire production. During the tire forming process, a tire forming machine is required. In the prior art, such as the patent CN202826442U, a nylon sleeve disc device for a semi-steel forming machine is disclosed, which includes a disc body and a nylon sleeve. The disc body is provided with a central hole, and an inlay groove is provided on the central hole. The nylon sleeve is inlaid on the inlay groove. The device has a simple structure, which can prevent metal iron filings from entering the tire interior due to the wear of the disc during long-term use, ensure the quality of the tire, and improve the safety performance of the tire. However, the edge surface of the disc and the matching surface of the tailstock of the forming machine are aligned for installation. In actual use, due to reasons such as tooling processing errors and manual installation errors, there is likely to be a height difference between the edge surface of the disc and the matching surface of the tailstock of the forming machine. During the process of the spring pressing the apex strip, passing through the uneven installation matching surface will cause jamming and non-smooth phenomena, which are likely to cause deformation of the apex strip pressing, resulting in a decline in tire performance. Summary of the Utility Model

The spring member 3 is movably installed on the platen outer edge plane 11 through a limiting device. The spring member 3 moves on it to press the apex rubber. The spring member 3 contacts the platen outer edge plane 11 through the limiting device, and it moves to the forming drum during the pressing process of the apex rubber. There is no height step difference during the movement of the spring member 3 on the platen outer edge plane 11. Therefore, during the process of transitioning from the platen outer edge plane 11 to the forming drum to press the apex rubber, it can be smooth and without jamming, avoiding the deformation of the apex rubber during pressing, improving the service life of the spring member 3, and ensuring the tire performance.

[0031] As an implementation manner, the platen outer edge plane 11 is arranged on the outside of the platen body 1.

The spring member 3 is arranged in the receiving groove. The receiving groove is used to limit and position the spring member 3. There is an installation spacing between the baffle portion 4 and the platen outer edge plane 11.

[0034] It can be understood that the diameter dimension of the spring member 3 is not greater than the dimension of the receiving groove.

[0035] As an implementation manner, the platen body 1 is installed on the tailstock 5 of the forming machine through a fastener 14, making the installation more stable and firm. It can be understood that the platen body 1 and the tailstock 5 of the forming machine are aligned and installed.

[0036] As an implementation manner, the platen body 1 is provided with a number of positioning holes 12 for connecting the fastener 14, and the fastener 14 is installed in the corresponding positioning holes 12.

[0037] As an implementation manner, an installation recess 13 is provided on the side surface of the platen body 1 corresponding to the tailstock 5 of the forming machine, which is convenient for the fixed installation of the platen body 1. The positioning holes 12 are evenly distributed in the installation recess 13.

[0038] It is understandable that the inlay part 10 is located inside the collision disc body 1, and the nylon sleeve 2 is arranged inside the collision disc body 1. The installation recess 13 is located on the left side surface of the collision disc body 1.

[0039] As an implementation manner, the number of the positioning holes 12 is 4 - 8. Preferably, the number of the positioning holes 12 is 6.
