Description

Technical Field

[0001] The utility model relates to the technical field of tire processing, in particular to a tire bead ring clamping and transferring device and a molding machine. Background Art

[0002] In the past, the standard tire production process of radial agricultural tires was generally produced and processed in a two-step process. The carcass tube produced in the first stage needs to be unloaded from the bonding drum by workers using a sling and transferred to the second-stage forming drum. At the same time, the second-stage belt drum completes the forming process of the tread assembly, and then the processed tread is transferred to the outside of the processed carcass tube on the forming drum through the belt layer transfer ring, and the tread and carcass tube are roll-formed by a rolling device to form a tire embryo to be vulcanized. Because the size and weight of agricultural tires are usually large, it is very labor-intensive and complicated for workers to transfer large-sized and heavy carcass tubes.

[0003] A few high-end radial agricultural tire building machines are equipped with carcass transfer rings, which have the functions of completing the tire bead on the carcass tube before the turn-up and transferring the carcass tube and tire bead before the turn-up to the building drum. Such transfer rings are generally composed of four or more rings, occupying a large space and having complex rings. Since most of the components such as the inner liner and cord of agricultural tires do not have steel wires but softer wire harnesses, the carcass tube before the turn-up needs to be transferred by the sidewall expansion ring to open one end of the carcass tube and move it to the building drum so that the tube can be smoothly transferred to the building drum, and the risk of failure in transferring the carcass tube is high.

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0031] In order to solve the problem of high labor intensity of manually transferring tire body tubes in the processing of radial agricultural tires in the prior art, the utility model provides a tire bead ring clamping and transferring device and a molding machine. The molding machine has the following tire bead ring clamping and transferring device.

[0032] like Figures 1 to 8A tire bead ring clamping and transferring device is shown, comprising a plurality of tire bead clamping rings 10 and a center ring 20, wherein tire bead clamping rings 10 are arranged on both axial sides of the center ring 20, the tire bead clamping rings 10 comprise a supporting ring body 11, a plurality of clamping assemblies 12 and a clamping drive assembly 13, wherein the supporting ring body 11 is axially movable relative to the center ring 20; the clamping assembly 12 is circumferentially arranged on the supporting ring body 11, and the clamping assembly 12 is radially movable, the clamping assembly 12 comprises a clamping pad 121 for clamping a tire body tube and a tire bead adsorption plate 122 located on one axial side of the clamping pad 121, the tire bead adsorption plate 122 and the side surface of the clamping pad 121 form a tire bead clamping area for clamping the tire bead, and the clamping pad 121 is axially movable to adjust the size of the tire bead clamping area; the clamping drive assembly 13 is drivingly connected to the clamping assembly 12, and drives the clamping assembly 12 to move radially to clamp the tire body tube.

[0033] In this embodiment, the tire bead clamping ring 10 and the center ring 20 cooperate with each other. Since the tire bead clamping ring 10 is provided with a clamping assembly 12, the clamping assembly 12 can clamp the tire body tube and other components, and cooperate with the axial movement of the tire bead clamping ring 10 to transfer the tire body tube, so that the device can complete the transfer of the tire body tube after the reverse packaging. At the same time, the clamping assembly 12 adopts the structure of a clamping tile 121 and a tire bead adsorption plate 122. The tire bead adsorption plate 122 can adsorb the tire bead, so as to achieve preliminary fixation of the tire bead. After adsorption, the clamping tile 121 can move axially to clamp the tire bead together with the tire bead adsorption plate 122, so as to achieve clamping of the tire bead. In this way, the pre-clamped tire bead can be put on the tire body tube before the tire body tube is reversed, so as to achieve the action of clamping the tire bead to the tire body tube before the reverse packaging. The above arrangement can not only clamp the tire bead to the tire body tube before the tire bead is turned up, but also complete the transfer of the tire body tube after the tire bead is turned up. Moreover, since the clamping tile 121 has axial movement, it can move toward the center ring 20, so that it can adapt to the transfer of tire body tubes with smaller widths, saving space. At the same time, the entire process of laminating and transferring the tire body tube is fully automatic, and workers do not need to unload the tube and re-clamp it, which can improve production efficiency, improve tire quality, and reduce workers' labor intensity. In addition, the tire bead ring clamping and transferring device of this embodiment can adopt a structural form of two tire bead clamping rings 10 and one center ring 20, that is, a tire bead clamping ring 10 is respectively arranged on both sides of a center ring 20, so that the structure is more compact and occupies less space.

[0034] It should be noted that the axial, radial and circumferential directions mentioned in this embodiment are all in terms of the overall shape of the bead ring clamping and transmitting device, that is, in terms of the direction of the bead clamping ring 10, or the center ring 20. In this embodiment, the bead clamping ring 10 and the center ring 20 are arranged in parallel, and their axes coincide with each other.

[0035] like Figure 4As shown, in this embodiment, the clamping drive assembly 13 adopts a connecting rod transmission structure. Specifically, the clamping drive assembly 13 includes a plurality of swing rods 131, a plurality of connecting rods 132 and a clamping drive member 133. The swing rods 131 are rotatably arranged on the supporting ring body 11. The clamping assembly 12 has a track bearing. The swing rod 131 has a slide groove. The track bearing is movably arranged in the slide groove. In this way, when the swing rod 131 rotates, the clamping assembly 12 can be driven to move radially through the cooperation between the slide groove and the track bearing. Since the clamping assembly 12 is generally provided with a plurality of swing rods 131, a plurality of swing rods 131 are also provided, and preferably, the swing rods 131 are provided one by one with the clamping assembly 12. In order to ensure the uniformity of the actions between the clamping assemblies 12, a connecting rod 132 is provided. The two ends of the connecting rod 132 are rotatably connected to two swinging rods 131 adjacent to each other in the circumferential direction. In this way, the two adjacent swinging rods 131 are associated with each other through the connecting rod 132, so that all the swinging rods 131 are associated with each other. As long as any swinging rod 131 rotates, the rotation of the swinging rod 131 will be transmitted to other swinging rods 131 through the connecting rod 132, thereby driving all the swinging rods 131 to rotate, so that the rotation of one swinging rod 131 can drive the effect of synchronous radial movement of all the clamping assemblies 12. The clamping drive 133 can be a motor or a cylinder. Since the connecting rod 132 and the swinging rod 131 are mutually associated, the clamping drive 133 only needs to be driven and connected with any one of the swinging rods 131 or the connecting rod 132, so that the clamping drive 133 drives the clamping assembly 12 to move synchronously radially through the swinging rod 131 and the connecting rod 132, thereby achieving the clamping effect on the carcass tube.

[0036] In this embodiment, since the swing rods 131 are associated with each other through the connecting rods 132, each swing rod 131 is connected to two connecting rods 132, so that the swing rod 131 has a first connection point and a second connection point connected to the connecting rods 132, the first connection point and the second connection point are located at the same end of the swing rod 131, and the first connection point and the second connection point are respectively located at the two ends of the length direction of the swing rod 131. In other words, the first connection point and the second connecting member 124 are both located at one end of the swing rod 131, and the sliding groove is located at the other end of the swing rod 131, and the rotation axis of the swing rod 131 is located in the middle position, so that the forces of the two connecting rods 132 on the swing rod 131 are the same for the rotation direction of the swing rod 131, thereby ensuring the consistency of transmission. The swing rod 131 of this embodiment adopts a bent two-stage structure, and the rotation axis is located at the bent position between the two ends. Of course, the specific matching mode between the swing rod 131 and the connecting rod 132, the specific structure of the swing rod 131, etc. can be adjusted accordingly as needed, as long as it can achieve the radial movement of the clamping assembly 12.

[0037] In this embodiment, the support ring body 11 has a central area for accommodating the carcass tube and a plurality of radially arranged slide rails 111, each slide rail 111 is arranged on the peripheral side of the central area, and the clamping assembly 12 is movably arranged on the slide rail 111, thereby ensuring that the clamping assembly 12 as a whole can only move radially along the slide rail 111, thereby ensuring the stability of movement and the reliability of clamping.

[0038] like Figure 5 and Figure 6 As shown, in the present embodiment, the clamping assembly 12 further includes a radial slide 123, a connecting member 124 and a tire bead driving member 125. The radial slide 123 is the main part of the clamping assembly 12, and is radially movably connected to the slide rail 111 on the support ring body 11. The clamping pad 121 is installed on the radial slide 123 and is axially movably connected to the radial slide 123. In this way, on the one hand, the clamping pad 121 can cooperate with the tire bead suction plate 122 when clamping the tire bead to achieve the clamping of the tire bead. On the other hand, the clamping width can be further adjusted when clamping the tire body tube, so that a tire body tube with a smaller width can be clamped, which has higher applicability. One end of the connecting member 124 is connected to the radial slide 123, and the other end of the connecting member 124 is spaced apart from the clamping pad 121, where the tire bead adsorption plate 122 is located, so that the distance between the clamping pad 121 and the tire bead adsorption plate 122 can be changed when the clamping pad 121 moves axially, thereby adjusting the size of the tire bead clamping area, thereby achieving the clamping and releasing of the tire bead. The tire bead driving member 125 can be a motor, a cylinder or other components, which is connected to the clamping pad 121 and drives the clamping pad 121 to move relative to the radial slide 123. A plate-shaped clamping portion can be separately provided at the end of the clamping pad 121, so as to better cooperate with the tire bead adsorption plate 122.

[0039] The connecting piece 124 of the present embodiment includes a first section and a second section connected in sequence, wherein the first section extends axially and the second section extends radially, so that the connecting piece 124 as a whole forms an inverted L-shaped structure, wherein the first axial section is connected to the radial slide plate 123, and the tire bead suction plate 122 is located at the end of the second radial section, so that a distance can naturally be formed between the tire bead suction plate 122 and the clamping pad 121, thereby forming a tire bead clamping area of ​​adjustable size to achieve clamping of the tire bead.

[0040] Preferably, the tire bead absorption plate 122 of the present embodiment is a magnetic part, so that when the tire bead is placed on the side with the tire bead absorption plate 122, the tire bead can be automatically absorbed on the tire bead absorption plate 122, thereby realizing rapid placement of the tire bead, and after placement, further clamping is achieved by moving the clamping pad 121.

[0041] In this embodiment, the clamping assembly 12 further includes a suction cup 126, which is connected to the clamping tile 121. The suction cup 126 can suck air under negative pressure, thereby sucking the carcass tube under negative pressure when clamping the carcass tube, thereby achieving the function of assisting in clamping the carcass tube. Figure 7 and Figure 8 The number and specific location of the suction cups 126 can be adjusted accordingly as needed.

[0042] like Figure 1 and Figure 2 As shown, in the present embodiment, the tire bead ring clamping and transmission device also includes a base 30, and the center ring 20 and the tire bead clamping ring 10 are both arranged on the base 30, wherein the center ring 20 is fixedly arranged on the base 30 by means of bolts or the like, and the tire bead clamping ring 10 is movably arranged relative to the base 30, and the tire bead clamping ring 10 and the base 30 can also be matched by setting a track, so that the position of the tire bead clamping ring 10 can be adjusted, thereby changing the distance between the tire bead clamping ring 10 and the center ring 20, thereby achieving the clamping of the tire body tube and the adjustment of the position in some cases.

[0043] The tire bead ring clamping and transmission device of this embodiment also includes a guide member 40. The guide member 40 can be a column with a certain length. The guide member 40 is axially arranged and penetrates into the tire bead clamping ring 10, thereby guiding the axial movement of the tire bead clamping ring 10.

[0044] The bead ring clamping and transferring method corresponding to the bead ring clamping and transferring device of this embodiment is specifically as follows:

[0045] When the tire bead is transported to the tire bead clamping area by the tire bead presetting device, the tire bead suction plate 122 suctions the tire bead, the size of the tire bead clamping area is reduced, and the tire bead suction plate 122 and the clamping tile 121 clamp the tire bead together;

[0046] The bead clamping ring 10 moves axially and adjusts the distance between it and the center ring 20;

[0047] The bead ring clamping and transferring device moves as a whole and transfers the bead to a predetermined position on the bonding drum, the size of the bead clamping area increases and releases the bead, and the bead is transferred to the bonding drum;

[0048] The tire bead clamping ring 10 moves axially and positions the clamping assembly 12 toward the bonding tube formed by the bonding drum. The clamping assembly 12 contracts radially and clamps the carcass tube. The tire bead ring clamping and transferring device moves as a whole and transports the carcass tube to the forming drum.

[0049] In the above process, after the bead suction plate 122 suctions the bead, the clamping shoe 121 is driven by the bead driving member 125 to move toward the bead suction plate 122 to reduce the size of the bead clamping area.

[0050] After the tire bead is transferred to the bonding drum and the bonding roll forming is completed on the bonding drum to form the tire body tube after the forming, the clamping drive 133 drives the clamping assembly 12 to radially expand and contract to the diameter required for clamping the tire body tube through the swing rod 131 and the connecting rod 132, and the tire bead clamping ring 10 moves axially to the width required for clamping the tire body tube, or the tire bead clamping ring 10 moves axially and the clamping pad 121 moves relative to the radial slide 123 in the direction close to the center ring 20, so that the clamping assembly 12 is aligned with the tire body tube, the clamping pad 121 clamps the tire body tube, and the suction cup 126 adsorbs the tire body tube. Whether the tire bead clamping ring 10 only needs to move as a whole or both the tire bead clamping ring 10 and the clamping pad 121 need to move is selected according to the specific width of the carcass tube. When the tire bead clamping ring 10 moves as a whole so that the width between the clamping pads 121 can meet the needs of clamping the carcass tube, the clamping pad 121 does not need to be moved separately. When the tire bead clamping ring 10 moves as a whole so that the width between the clamping pads 121 can meet the needs of clamping the carcass tube, the clamping pad 121 needs to be moved axially separately to adapt to the carcass tube with a smaller width.

[0051] It should be noted that, the multiple in the above embodiments refers to at least two.

[0052] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0053] 1. It solves the problem of high labor intensity of manually transferring the tire body tube during the processing of radial agricultural tires in the prior art;

[0054] 2. It can not only clamp the tire bead to the tire body tube before turning up, but also complete the transfer of the tire body tube after turning up;

[0056] 4. The entire process of laminating and transferring the carcass tube is completed automatically, without the need for workers to unload the tube or re-install the card, which can improve production efficiency, improve tire quality, and reduce workers' labor intensity;

[0057] 5. The structure is more compact and occupies less space.
