Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tire production, and in particular to an aircraft tire rubber core heat-bonding pre-bending device. Background Technology

[0002] In the production of aircraft tires, the left and right sides of the tire contain a rubber core with a triangular cross-section. Since the rubber core is purchased in rolls, it needs to be cut into a specified length during production. Then, the rubber core is wound into a mold and placed in a heating furnace to bend and shape the rubber core into a circle.

[0003] Existing pre-bending devices, such as the tire core heat-applied pre-bending device disclosed in utility model patent application number 201921894987.0, mainly include a base with a main shaft vertically mounted on its upper end. A rotating ring is rotatably mounted on the main shaft via bearings. The outer end of the rotating ring has a groove along the circumferential direction that matches the cross-sectional shape of the rubber core. The circumference of the arc-shaped groove matches the length of the rubber core. The heating wire is circular and located between the rotating ring and the main shaft. The heating wire is fixed to the main shaft via bracket I. In use, the cut end of the rubber core is fixed in the groove by the rubber core locking mechanism. Then, the pressing mechanism presses the rubber core into the groove. The rotating ring drive mechanism drives the rotating ring to rotate around the main shaft via bearings, thereby pressing the entire rubber core into the groove under the action of the pressing mechanism. When the heating wire is energized, it generates heat to heat the rubber core wound on the rotating ring, thus achieving bending and shaping.

[0004] However, after the rubber core is pre-bent by heat application, it still needs a long time to cool and set, which affects work efficiency. Moreover, the rubber core needs to be manually removed from the device after setting, which is very troublesome. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a heat-applied pre-bending device for aviation tire rubber cores that not only allows for timely cooling after heating and bending the rubber core, thus improving work efficiency, but also facilitates unloading the rubber core after shaping, thereby reducing the labor intensity of workers.

[0006] This utility model discloses a pre-bending device for heat-applying aviation tire rubber cores, comprising a feeding mechanism; it also includes a rotating mechanism, a clamping mechanism, two sets of pushing mechanisms, and a cooling mechanism. The rotating mechanism is mounted on the feeding mechanism and drives the rubber core to rotate and bend. The clamping mechanism is mounted on the rotating mechanism and cooperates with the rotating mechanism to fix the rubber core. Both sets of pushing mechanisms are mounted on the feeding mechanism and push the rubber core off the rotating mechanism. The cooling mechanism is mounted on the feeding mechanism and cools the rubber core. The operator inserts the first end of the rubber core into the slots of the rotating mechanism and the clamping mechanism, starts the rotating mechanism to drive the rubber core to rotate and bend, and heats the rubber core to maintain its bent state. Then, the cooling mechanism cools the rubber core, the clamping mechanism retracts, and the two sets of pushing mechanisms push the rubber core onto the feeding mechanism, which then drives the rubber core to be fed out.

[0007] Preferably, the feeding mechanism includes a worktable, a back plate, and a conveyor belt. The bottom end of the worktable is connected to the ground, the bottom end of the back plate is connected to the top end of the worktable, and the conveyor belt is installed on the worktable. Two sets of pushing mechanisms push the rubber core onto the conveyor belt, and the conveyor belt drives the rubber core to feed.

[0008] Preferably, the rotating mechanism includes a motor, a first reducer, a transmission shaft, a first fixed frame, and a heating plate. The motor is mounted on a back plate, the first reducer is mounted on the back plate, the transmission shaft is rotatably mounted on the back plate, the first fixed frame is mounted on the transmission shaft, and the first fixed frame has a feed notch, a discharge notch, and multiple sets of guide grooves. The heating plate is mounted on the first fixed frame. The operator inserts the end of the rubber core into the first fixed frame through the feed notch. The first fixed frame, in conjunction with the clamping mechanism, fixes the rubber core. The motor is started, and the motor drives the transmission shaft to rotate through the first reducer. The transmission shaft drives the first fixed frame to rotate, thereby making the rubber core tightly adhere to the first fixed frame. The heating plate heats the rubber core, keeping the rubber core in a bent state.

[0009] Preferably, the clamping mechanism includes a cylinder, multiple sets of piston rods, multiple sets of second fixing frames, and multiple sets of positioning strips. The cylinder is mounted on the first fixing frame, the multiple sets of piston rods are all mounted on the cylinder, the multiple sets of second fixing frames are respectively mounted on the multiple sets of piston rods, and the multiple sets of positioning strips are respectively mounted on the multiple sets of second fixing frames and are slidably mounted in multiple sets of guide grooves in the first fixing frame. The second fixing frames cooperate with the first fixing frame to fix the rubber core. When the rubber core is bent and shaped, the cylinder drives the multiple sets of piston rods to retract, and the multiple sets of positioning strips drive the multiple sets of second fixing frames to retract, which facilitates the two sets of pushing mechanisms to push the rubber core down. By setting multiple sets of positioning strips, it is convenient to guide the multiple sets of second fixing frames and ensure that the second fixing frames move smoothly.

[0010] Preferably, the pushing mechanism includes a hydraulic cylinder, a push plate, and a pressing roller. The hydraulic cylinder is mounted on the back plate, the push plate is mounted on the hydraulic cylinder, and the pressing roller is rotated and mounted on the push plate. The pressing roller presses the rubber core so that the rubber core is close to the heating plate to ensure the heating and shaping effect. When the clamping mechanism retracts, the two sets of hydraulic cylinders are activated. The two sets of hydraulic cylinders push the two sets of push plates close to the rubber core and push the rubber core off the first fixed frame through the discharge notch of the first fixed frame.

[0011] Preferably, the push plate is made of polyetheretherketone (PEEK); PEEK has low thermal conductivity and good heat insulation properties, and will not be heated by the heating plate, thus avoiding adhesion to the core when pushing it.

[0012] Preferably, the cooling mechanism includes a servo motor, a second reducer, a rotating shaft, a water tank, a water inlet pipe, a valve, and three sets of water-cooled rollers. The servo motor is mounted on the back plate, the second reducer is mounted on the back plate, the rotating shaft is rotatably mounted on the back plate, the water tank is mounted on the rotating shaft, the bottom end of the water inlet pipe is connected to the top of the water tank, the valve is mounted on the water inlet pipe, and the three sets of water-cooled rollers are rotatably mounted on the water tank and connected to the inside of the water tank. The operator opens the valve to deliver cooling water to the water tank through the water inlet pipe, starts the servo motor, and the servo motor drives the rotating shaft to rotate through the second reducer, causing the three sets of water-cooled rollers to press down on the rubber core. Cooling water flows into the three sets of water-cooled rollers to cool and shape the rubber core. After the rubber core is shaped, the servo motor is started to drive the water-cooled rollers to rotate in the opposite direction and tilt up, so that the cooling water can flow back into the water tank for circulation.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the operator inserts the first end of the rubber core into the slot of the rotating mechanism and the clamping mechanism, starts the rotating mechanism to drive the rubber core to rotate and bend, and heats the rubber core to keep it in a bent state. Then the cooling mechanism cools the rubber core, the clamping mechanism retracts, and the two sets of pushing mechanisms push the rubber core onto the unloading mechanism. The unloading mechanism drives the rubber core to be unloaded. Attached Figure Description
