Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically an auxiliary tooling for improving the coaxiality of the tire tread transfer ring blocks in a tire forming machine. Background Technology

[0002] During tire molding, various components need to be bonded and assembled in a specific order and method. Common molding methods include drum molding and semi-drum molding. Drum molding involves bonding tire components sequentially onto a molding drum, using the drum's expansion and contraction to achieve component positioning and bonding. Semi-drum molding combines the advantages of drum molding with other molding methods, better adapting to the production of tires of different specifications. During molding, it is crucial to ensure a tight bond between components, free of air bubbles and wrinkles, to guarantee the overall performance of the tire.

[0003] The existing patent (authorization announcement number: CN213006683U) discloses a pneumatic locking device for clamping the belt layer transfer ring of an all-steel forming machine. The key technical points are: the two-position three-way single-electromagnetic valve that controls the locking action of the pneumatic lock cylinder is energized to supply air to the lock head, the lock head opens and releases the cylinder rod, and at the same time the two-position five-way double-electromagnetic valve is energized to supply air to the lower chamber of the pneumatic lock cylinder, the cylinder rod extends and pushes the moving ring to rotate a certain angle, the positive and negative thread adjusting rod drives the rotating arm to rotate around the fixed axis of the rotating arm, and drives the other end of the rotating arm to retract the pad and clamp the tire tread cylinder via the connecting pin.

[0004] However, the above technical solution still has certain defects. When it is necessary to adjust the coaxiality of the forming drum and the tread composite, the position of the entire auxiliary drum transfer ring needs to be adjusted. It is not possible to adjust the coaxiality by adjusting the length of the extended pad. Therefore, an auxiliary tooling for improving the coaxiality of the tread transfer ring pad of the forming machine is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary tooling for improving the coaxiality of the tread transfer ring blocks of a molding machine, so as to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An auxiliary tooling for improving the coaxiality of the tire tread transmission ring pads of a molding machine includes a cylinder, the output end of which is fixedly connected to a drive plate, and the bottom of the drive plate is fixedly mounted with a driven assembly for driving the tire to the shaft.

[0008] The driven component consists of a driven ring fixedly installed at the bottom of the drive plate. A limit plate is fixedly installed on the inner wall of the driven ring. A fixed ring is slidably installed on the inner wall of the limit plate. A fixing member is fixedly installed on the inner wall of the driven ring. One end of the fixing member is rotatably connected to one end of a rotating rod. The other end of the rotating rod is rotatably connected to a first telescopic block. The outer wall of the first telescopic block is slidably connected to the inner wall of a second telescopic block. One side of the second telescopic block is fixedly connected to one end of a connecting rod. A drive rod is fixedly installed on one end of the connecting rod. The other end of the connecting rod is rotatably connected to the fixed ring. An adjustment component is also provided on the other end of the drive rod.

[0009] As a further embodiment of this utility model: the adjustment component includes a torsion spring fitted on one end of the drive rod, a connecting block fitted on the other end of the torsion spring, a fixing block installed at the bottom of the connecting block, and a pressing block installed at the bottom of the fixing block.

[0010] As a further embodiment of this utility model: the fixing block consists of a nylon block fixedly installed at the bottom of the connecting block, a pin passing through the nylon block and the pressing block, and a limiting rod inserted at the center position on both sides of the nylon block, and the limiting rod also passes through the center position on both sides of the pressing block.

[0011] As a further embodiment of this utility model: the nylon block is 155.08mm long, 75mm wide, and 10mm thick; there are two holes with a diameter of 16mm at the center of both sides of the nylon block, and the holes with a diameter of 8mm at the four corners of the nylon block.

[0012] As a further embodiment of this utility model: the fixing member, rotating rod, first telescopic block, second telescopic block, connecting rod, driving rod, and adjusting assembly are all arranged in a circular array of thirteen groups along the center of the driven ring.

[0013] As a further embodiment of this utility model: the inner wall of the fixing ring is fixedly connected to one end of the fixing rod, and a limit ring is fixedly installed on the other end of the fixing rod.

[0014] As a further improvement of this utility model: the surface of the limiting ring is provided with a driving groove, the driving groove is provided with thirteen sets, and the outer wall of the driving rod slides within the inner wall of the driving groove.

[0015] As a further improvement of this utility model, the pressing block is a tile and is made of carbon steel.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model constructs a stable circumferential support system by setting multiple sets of components in a circular array around the center. Regardless of which direction the external force disturbs, the synergistic effect of the multiple sets of components can buffer and resist it. When the equipment vibrates during operation, the thirteen sets of components can absorb and disperse the vibration from different directions, avoiding structural damage caused by uneven local stress.

[0018] 2. This utility model allows for the insertion of a shim between the nylon block and the tile block to adjust the extension distance of the tile block, improve radial runout or uniformity, and avoid precision deviations that may be caused by adjusting the position of the auxiliary drum transmission ring.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-5As shown, an auxiliary tooling for improving the coaxiality of the tire tread transmission ring blocks of a molding machine includes a cylinder 1, a drive plate 2 fixedly connected to the output end of the cylinder 1, and a driven assembly 3 for driving the tire to the shaft fixedly installed at the bottom of the drive plate 2.

[0030] In this embodiment, the cylinder 1 performs a telescopic movement, which drives the drive plate 2 to move, thereby causing the driven component 3 to move as a whole, and forming and pressing the tire.

[0031] In one embodiment, such as Figure 2 and Figure 3 As shown, the driven component 3 consists of a driven ring 31 fixedly installed at the bottom of the drive plate 2. A limit plate 32 is fixedly installed on the inner wall of the driven ring 31. A fixing ring 4 is slidably installed on the inner wall of the limit plate 32. A fixing member 33 is fixedly installed on the inner wall of the driven ring 31. One end of the fixing member 33 is rotatably connected to one end of the rotating rod 34. The other end of the rotating rod 34 is rotatably connected to the first telescopic block 35. The outer wall of the first telescopic block 35 is slidably connected to the inner wall of the second telescopic block 36. One side of the second telescopic block 36 is fixedly connected to one end of the connecting rod 37. A drive rod 38 is fixedly installed on one end of the connecting rod 37. The other end of 7 is rotatably connected to the fixed ring 4, and the other end of the drive rod 38 is also provided with an adjustment component 8; the drive plate 2 is driven by the cylinder 1, and the output end of the cylinder 1 generates a horizontal thrust on the drive plate 2. The driven ring 31 will move together with the drive plate 2. At this time, due to the movement of the driven ring 31, the fixing part 33 will move accordingly, and the fixing part 33 will drive the first telescopic block 35 to rotate. At the same time, the first telescopic rod will drive the second telescopic rod to rotate along the connecting rod 37, and will also drive the connecting rod 37 to rotate on the fixed ring 4, so that the drive rod 38 on the other side of the fixed ring 4 will also rotate with the connecting rod 37, in order to drive the tile to press the tire.

[0032] In one embodiment, such as Figure 4 As shown, the adjustment assembly 8 includes a torsion spring 81 fitted on one end of the drive rod 38, a connecting block 82 fitted on the other end of the torsion spring 81, a fixing block 83 installed at the bottom of the connecting block 82, and a pressing block 84 installed at the bottom of the fixing block 83. When the drive rod 38 rotates, it will drive the torsion spring 81 to rotate accordingly. At the same time, the connecting block 82 presses the pressing block 84, applying pressure to the tire. When the output end of the cylinder 1 returns to its original position, the elastic force generated by the torsion spring 81 after being twisted will drive the pressing block 84 to return to its original position, so that the fixing block 83 stops pressing the tire surface and releases the tire.

[0033] In one embodiment, such as Figure 5As shown, the fixing block 83 consists of a nylon block 831 fixedly installed at the bottom of the connecting block 82, a pin 832 passing through the nylon block 831 and the pressing block 84, and limiting rods 833 inserted into the center positions on both sides of the nylon block 831. The limiting rods 833 also pass through the center positions on both sides of the pressing block 84. Nylon is an engineering plastic with excellent comprehensive properties, possessing high strength, good wear resistance, self-lubricating properties, and a certain degree of toughness. These characteristics enable the nylon block 831 to withstand certain pressure and friction in the fixing block 83 structure. The nylon block 831 not only provides a basic platform for the installation of subsequent components but also buffers and disperses pressure from above or around to a certain extent, protecting other components from excessive impact and damage.

[0034] As a supplement: the connecting block 82 is driven by the drive rod 38, which transmits force to the nylon block 831. The nylon block 831 is tightly connected to the pressing block 84 through the pin 832 and the limiting rod 833, so that the force can be evenly distributed on the pressing block 84. Under the constraint of the nylon block 831 and the limiting rod 833, the pressing block 84 can accurately perform the corresponding actions to press the tire surface.

[0035] In one embodiment, such as Figure 5 As shown, the nylon block 831 is 155.08mm long, 75mm wide, and 10mm thick. There are two 16mm diameter holes at the center of both sides of the nylon block 831, and 8mm diameter holes at the four corners. The two holes are mainly used to install the limiting rod 833. The 16mm hole diameter needs to be precisely matched to the outer diameter of the limiting rod 833 to ensure that the limiting rod 833 can be tightly inserted and smoothly pass through the nylon block 831 and the pressing block 84. Simultaneously, a shim can be inserted between the nylon block 831 and the tile to adjust the extension distance of the tile, improve radial runout or uniformity, and avoid accuracy deviations that may be caused by adjusting the position of the auxiliary drum transmission ring.

[0036] In one embodiment, such as Figure 1 As shown, the fixing component 33, rotating rod 34, first telescopic block 35, second telescopic block 36, connecting rod 37, driving rod 38, and adjusting assembly 8 are all arranged in a circular array of thirteen groups around the center of the driven ring 31. These multiple groups of components form a stable circumferential support system. During mechanical operation, regardless of the direction of external force interference, the synergistic action of these multiple groups of components can buffer and resist it. When vibration occurs during equipment operation, the thirteen groups of components can absorb and disperse the vibration from different directions, preventing structural damage due to uneven local stress. This greatly improves the stability and reliability of the entire mechanical structure, enabling it to operate stably under complex working conditions.

[0037] In one embodiment, such as Figure 2As shown, the inner wall of the fixing ring 4 is fixedly connected to one end of the fixing rod 5, and the other end of the fixing rod 5 is fixedly installed with a limiting ring 6. The surface of the limiting ring 6 is provided with a driving groove 7, and the driving groove 7 is provided with thirteen sets. The outer wall of the driving rod 38 slides in the inner wall of the driving groove 7. The limiting ring 6 limits the range of movement of the driving rod 38 to prevent the driving rod 38 from moving beyond the range.

[0038] In one embodiment, such as Figure 5 As shown, the pressing block 84 is a tile made of carbon steel. During frequent use, there is continuous friction between the tile and the tire blank and the mold. The good wear resistance of carbon steel ensures that the surface wear of the tile is small after long-term operation, maintaining its original shape and dimensional accuracy.

[0039] The above embodiment discloses an auxiliary tooling for improving the coaxiality of the tire tread transmission ring pads in a molding machine. The driven ring 31 is driven by a cylinder 1, which simultaneously drives multiple sets of nylon blocks 831 and pads to press down and clamp the tire surface. At the same time, shims can be inserted between the nylon blocks 831 and pads to adjust the extension distance of the pads, improve radial runout or uniformity, avoid the accuracy deviation that may be caused by adjusting the position of the auxiliary drum transmission ring, and absorb and disperse vibrations from different directions through thirteen sets of components, thereby improving the stability of the equipment.

[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
