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

[0020] 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.

[0022] In order to solve the problem of long turn-up time of engineering tire in the prior art, the utility model provides an engineering tire one-step forming turn-up device and an engineering tire one-step forming machine, wherein the engineering tire one-step forming machine includes the following engineering tire one-step forming turn-up device.

[0023] like Figure 1 The device for forming and turning up an engineering tire in one step as shown includes a forming drum 10, a turn-up capsule 20 and a booster assembly 30. The turn-up capsule 20 is inflatably arranged on the side of the forming drum 10, and the booster assembly 30 is located on the axial side of the forming drum 10. At least a part of the booster assembly 30 is axially movable relative to the forming drum 10 and can move in a direction close to the turn-up capsule 20 to squeeze the turn-up capsule 20 to turn up the sidewall.

[0024] In this embodiment, the booster assembly 30 is provided to squeeze the turn-up capsule 20, so that the turn-up capsule 20 completes the turn-up action, thereby improving the turn-up efficiency. Specifically, the booster assembly 30 can move axially along the forming drum 10 to approach and squeeze the turn-up capsule 20, so that the turn-up capsule 20 is deformed to complete the turn-up action. Compared with the traditional method of using the booster capsule to deform and squeeze the turn-up capsule 20, this method of the booster assembly 30 directly acts on the turn-up capsule 20, which can quickly turn up the sidewall, shorten the turn-up time, and improve work efficiency. In addition, compared with the booster capsule, the booster assembly 30 has a longer service life. At the same time, the turn-up process of the engineering tire one-step forming turn-up device of this embodiment can be automatically realized, with a low degree of manual participation, reducing manual operations, reducing operating intensity, improving the accuracy and efficiency of tire forming, and improving the level of intelligent manufacturing.

[0025] It should be noted that the axial direction of the forming drum 10 refers to Figure 1 The left and right direction in .

[0026] In this embodiment, the boosting assembly 30 includes a boosting plate 31, which is movably arranged along the axial direction of the forming drum 10 and can squeeze the turn-up capsule 20. The boosting plate 31 has a boosting surface facing the turn-up capsule 20, and the boosting surface has an arc-shaped surface that is concave in the direction away from the turn-up capsule 20. In this way, when the boosting plate 31 moves along the axial direction of the forming drum 10 to approach the turn-up capsule 20, the boosting surface squeezes the turn-up capsule 20 to deform it, and the arc-shaped surface can fit the expanded shape of the turn-up capsule 20 to improve the turn-up accuracy of the sidewall. Preferably, the edge of the boosting surface is rounded to better match the expanded shape of the turn-up capsule 20 and improve the turn-up accuracy.

[0027] In this embodiment, the boosting surface also has a plane, the arcuate surface is located at the edge of the boosting surface and extends along the circumference of the boosting surface, and the plane is located on the inner side of the arcuate surface. In this way, on the one hand, the plane is located at the center of the boosting surface, so that as the boosting disk 31 extends toward the forming drum 10, the plane can quickly form a large-area contact with the turn-up capsule 20, so that the turn-up capsule 20 can be quickly deformed. On the other hand, when performing the turn-up action, the boosting surface cooperates with the turn-up capsule 20 after inflation to deflate and squeeze, and the plane can evenly squeeze the turn-up capsule 20, thereby reducing the thickness of the turn-up capsule 20 along the axial direction of the forming drum 10, so that the circumferential position where the turn-up capsule 20 contacts the arcuate surface has more gas, that is, there is more gas at the edge of the turn-up capsule 20, and the shape of the arcuate surface makes the edge of the sidewall receive a greater extrusion force, thereby realizing the turn-up of the sidewall, thereby improving the turn-up effect.

[0028] Preferably, the plane is a circular surface, the arcuate surface is an annular surface, and the centers of the plane and the arcuate surface are the same as the center of the boosting surface, that is, the boosting surface is divided into an inner circle and an outer circle, the inner circle is a plane, and the outer circle is an arcuate surface. In this way, when the boosting surface squeezes the turn-up capsule 20, the annular arcuate surface matches the shape at the edge of the sidewall, thereby ensuring the turn-up effect of the sidewall. At the same time, the force applied to the turn-up capsule 20 at each circumferential position of the arcuate surface is the same, so that the deformation of the turn-up capsule 20 is consistent, thereby ensuring the turn-up effect of the sidewall.

[0029] In this embodiment, there are multiple booster assemblies 30, and booster assemblies 30 are arranged on both sides of the axially opposite sides of the forming drum 10, and the booster assemblies 30 on both sides act synchronously. Specifically, there are two booster assemblies 30 in this embodiment, which are symmetrically arranged on both sides of the forming drum 10, and can move synchronously in the direction of approaching and moving away from the forming drum 10, so as to synchronously squeeze and move away from the reversed capsule 20, so as to complete the reversed packaging on both sides at the same time, ensure the reversed packaging effect and improve the work efficiency.

[0030] In this embodiment, the boosting assembly 30 includes a boosting plate 31, a driving member 32 and a transmission assembly 33, and the transmission assembly 33 is drivingly connected to the driving member 32; the boosting plate 31 is connected to the transmission assembly 33, and the driving member 32 drives the boosting plate 31 to approach and move away from the reversed capsule 20 through the transmission assembly 33. The driving member 32 and the transmission assembly 33 are arranged on the side of the boosting plate 31 away from the forming drum 10 to avoid the movement of the boosting plate 31. When performing the reversed action, the driving member 32 drives the transmission assembly 33 to drive the boosting plate 31 to approach the reversed capsule 20 and squeeze the reversed capsule 20 to complete the reversed action. After the reversed action is completed, the driving member 32 drives the transmission assembly 33 to drive the boosting plate 31 away from the reversed capsule 20 to make the reversed capsule 20 return to the initial position.

[0031] Optionally, the driving member 32 may use a motor, a cylinder, etc., and the transmission assembly 33 may use a chain, a lead screw, a screw, etc., so that the driving member 32 can drive the booster plate 31 to perform linear motion through the transmission assembly 33.

[0032] In this embodiment, the transmission assembly 33 includes a chain assembly 331 and a ball screw assembly 332, the chain assembly 331 is drivingly connected to the driving member 32; the ball screw assembly 332 is drivingly connected to the chain assembly 331 and connected to the boosting plate 31, so that the driving member 32 drives the boosting plate 31 to approach and move away from the reversed capsule 20 through the chain assembly 331 and the ball screw assembly 332. Of course, the transmission assembly 33 can also use other transmission components as needed.

[0033] In this embodiment, the engineering tire one-step forming and turning-up device further includes a first box assembly 40, the first box assembly 40 has an output shaft 41, the forming drum 10 is sleeved on the output shaft 41, and rotates under the drive of the output shaft 41, and the boosting assembly 30 is arranged on the first box assembly 40. Specifically, considering the action of avoiding the boosting plate 31, in addition to the output shaft 41, the first box assembly 40 is arranged on the side of the boosting plate 31 away from the forming drum 10, the driving member 32 and the transmission assembly 33 are also arranged in the first box assembly 40, and the output shaft 41 passes through the side of the first box assembly 40 close to the boosting plate 31 to connect with the forming drum 10, so that, on the one hand, the output shaft 41 can drive the forming drum 10 to rotate, and on the other hand, the output shaft 41 can simultaneously support the boosting plate 31 and the forming drum 10, so that the boosting plate 31 and the forming drum 10 are located on the same axis to improve the turning-up accuracy.

[0034] In this embodiment, the first box assembly 40 includes a rotating expansion and contraction assembly 42, which is driven and connected to the forming drum 10. The rotating expansion and contraction assembly 42 may include two sub-components, which can respectively drive the forming drum 10 to rotate and flatten to ensure the reverse packaging effect.

[0035] In this embodiment, the engineering tire one-step forming and turning-up device further includes a second box assembly 50. The first box assembly 40 and the second box assembly 50 are respectively located on two axially opposite sides of the forming drum 10. The second box assembly 50 mainly plays the role of auxiliary support. Since two booster assemblies 30 are provided in this embodiment, one of the booster assemblies 30 is provided on the first box assembly 40, and the other booster assembly 30 is provided on the second box assembly 50. At the same time, one end of the output shaft 41 extending out of the first box assembly 40 is supported on the second box assembly 50, thereby improving the reliability of the output shaft 41 and extending its service life. The second box assembly 50 may not be provided with a rotating expansion and contraction assembly 42, or a rotating expansion and contraction assembly 42 may be provided as required.

[0036] The operation process of the engineering tire one-step forming and reverse packaging device is as follows:

[0037] 1. After the pre-inversion process is completed, the inversion capsule 20 is inflated, and the driving member 32 drives the chain assembly 331 to drive the ball screw to rotate, thereby driving the booster plate 31 to extend to the specified position;

[0038] 2. After the inflation of the turn-up capsule 20 is completed, the booster plate 31 moves forward to squeeze the turn-up capsule 20, and at the same time, the turn-up capsule 20 is deflated to cooperate with the turn-up sidewall. After the turn-up is completed, the turn-up capsule 20 is quickly deflated, and the driving member 32 drives the chain assembly 331 to drive the ball screw to rotate, thereby driving the booster plate 31 to quickly return, and the booster plate 31 retreats to the initial position.
