Description

Technical Field

[0001] The utility model relates to a component structure of a tire building machine, in particular to a guide device for a steel ring on a giant tire building machine. Background Art

[0002] The buckle ring guide device of existing giant tire forming machines typically consists of two symmetrical guide rods on the turn-up mounting seat, driven by a pneumatic cylinder for guidance. At the same time, a square polytetrafluoroethylene slider is installed every 90 degrees along the circumference to reduce friction between the turn-up mounting seat and the buckle ring mounting seat. However, this guide device has the following disadvantages: 1. The sliders must be milled on the turn-up mounting seat before installation, and then the slider outer circle must be machined, which complicates the component structure and processing technology. 2. The four partially embedded sliders only occupy approximately 1 / 3 of the circumference of the turn-up mounting seat, making intermittent support prone to jamming. Furthermore, the guide rods are also arranged circumferentially, making concentricity adjustment difficult. This results in a left-right swaying and creeping phenomenon during buckling, causing the buckle ring to be loose and increasing the number of failure points. 3. The rotating disk is in direct contact with the buckle ring mounting seat, resulting in high steel-to-steel friction resistance. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a buckle ring guide device for a forming machine, which has the advantages of simple and reliable structure, fewer processing steps, and easy replacement and maintenance.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] The buckle ring guide device of the forming machine includes a turn-up mounting seat, a buckle ring mounting seat, a rotating disk, a wide wear-resistant belt, a narrow wear-resistant belt, a guide groove, a bolt roller needle bearing, a cylinder, and a double earring support. The wide wear-resistant belt is arranged in a ring shape between the turn-up mounting seat and the buckle ring mounting seat, and the narrow wear-resistant belt is arranged in a ring shape between the buckle ring mounting seat and the rotating disk. A guide groove is opened axially on the turn-up mounting seat, and a bolt roller needle bearing that can move along the guide groove is installed on the buckle ring mounting seat. The cylinder on the turn-up mounting seat can drive the buckle ring mounting seat to move axially through the double earring support to perform the buckle ring operation.

[0006] Furthermore, there are two wide wear-resistant belts, one of which is installed in the groove on the upper surface of the outer circle of the turn-up mounting seat, and the other is installed in the groove on the lower surface of the inner circle of the buckle ring mounting seat.

[0007] Furthermore, there are four guide grooves, which are evenly distributed along the circumference of the turn-up mounting seat.

[0008] Compared with the prior art, the advantages and effects of the present invention are:

[0009] 1. Installing a wide annular wear-resistant belt between the turn-up mounting seat and the buckle ring mounting seat can not only reduce friction resistance, but also provide continuous support for the entire circumference to avoid jamming. At the same time, the guide groove and the bolt roller needle bearing work together to provide axial guidance to prevent rotation or swinging of the buckle ring.

[0010] 2. Install an annular narrow wear-resistant belt at the joint between the buckle ring mounting seat and the rotating disk to reduce the relative wear between the components;

[0011] 3. The device has a simple structure, few processing steps, and is easy to replace and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below with reference to the following embodiments, but the present invention is not limited to these embodiments.

[0016] The buckle ring guide device of the forming machine described in this embodiment is as follows: Figure 1 and 2 As shown, it includes an inverted mounting seat 1, a buckle ring mounting seat 2, a rotating disk 3, a wide wear-resistant belt 4, a narrow wear-resistant belt 5, a guide groove 6, a bolt roller needle bearing 7, a cylinder 8, and a double earring support 9.

[0017] like Figure 1 and 2 As shown, a wide wear-resistant belt 4 is annularly disposed between the turn-up mounting seat 1 and the buckle ring mounting seat 2. Two belts are provided, one of which is mounted in a groove on the outer surface of the turn-up mounting seat 1, and the other is mounted in a groove on the inner surface of the buckle ring mounting seat 2. A narrow wear-resistant belt 5 is annularly disposed between the buckle ring mounting seat 2 and the rotating disk 3, specifically mounted in a groove on the outer surface of the buckle ring mounting seat 2.

[0018] like Figure 1 and 2 As shown, four guide grooves 6 opened in the axial direction are evenly distributed along the circumference of the turn-up mounting seat 1, and a bolt roller needle bearing 7 that can move along the guide groove 6 is installed on the buckle ring mounting seat 2.

[0019] like Figure 1 As shown, the cylinder 8 is fixed on the turn-up mounting seat 1, and the cylinder rod of the cylinder 8 is connected to the double earring support 14 on the buckle ring mounting seat 2.

[0020] like Figure 2 As shown, the pin shaft 10 provided with a guide sleeve 11 passes through the Archimedean spiral groove on the rotating disk 3 and is fixed to the buckle ring clamp 13 through the pressure cover 12. The front end of the buckle ring mounting seat 2 has a T-shaped slot, and the buckle ring clamp 13 can move in the slot. The buckle ring clamp 13 is tensioned by the transmission of the pin shaft 10. The steel ring 14.

[0021] The working principle of this embodiment is as follows:

[0022] 1. The cylinder 8 pushes the buckle ring mounting seat 2 forward through the double earring support 9, and the steel ring 14 tensioned on the buckle ring clamp 13 is buckled. The bolt roller needle bearing 3 moves along the guide groove 6 to provide axial guidance for forward movement. The two wide wear-resistant belts 4 installed between the turn-up mounting seat 1 and the buckle ring mounting seat 2 can provide continuous support on the circumference to prevent rotation or swinging during buckling.

[0023] 2. When the rotating disk 3 rotates, the pin 10 with the guide sleeve 11 drives the buckle ring clamp 13 to move, tightening or loosening the steel ring 14. The buckle ring mounting seat 2 and the rotating disk 3 are equipped with a narrow wear-resistant belt 5 to reduce friction.
