Description

Technical Field

[0001] This utility model relates to the technical field of tire production, and in particular to a vulcanizing machine for producing rubber aircraft tires with uniform pressure. Background Technology

[0002] Tire vulcanization is a core process in tire manufacturing. Through a chemical cross-linking reaction, it transforms plastic raw rubber into a highly elastic rubber material, giving tires the necessary mechanical strength, wear resistance, and high-temperature resistance, thus improving tire quality. In the prior art, a utility model patent with patent application number 202211629171.1 discloses a tire vulcanization device, mainly composed of a vulcanizing tank and a mold. During vulcanization, the tire is placed in the mold, then heated and compressed within the mold to vulcanize it. The tire is then removed from the mold. However, this device has the following problems: after vulcanization, the tire temperature is high, making it inconvenient to manually remove the tire from the mold. Therefore, a vulcanization device is needed to assist workers in removing the tire from the lower mold. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a vulcanizing machine for producing rubber aircraft tires that can assist workers in moving the tire blanks to a tray after vulcanization, thus avoiding burns to workers during tire removal, facilitating the handling of tire blanks, and providing high practicality and uniform pressure.

[0004] This utility model discloses a vulcanizing machine for producing rubber aircraft tires with uniform pressure. It includes a lower mold, a vulcanizing bladder, an air supply pipe, an exhaust pipe, an upper mold, and a base plate. The vulcanizing bladder is mounted on the lower mold. An air supply pipe is provided on the vulcanizing bladder and communicates with it. An exhaust pipe is provided on the air supply pipe and communicates with it. Valves are provided on both the air supply pipe and the exhaust pipe. The upper mold is located above the lower mold and has multiple heating plates, the heating ends of which are embedded in the inner wall of the upper mold. It also includes... The system comprises a tray, a lifting mechanism, a moving mechanism, and a tire-retrieving mechanism. The upper mold is mounted on the lifting mechanism, which is used to raise and lower the upper mold. The tray is mounted on a base plate. The lower mold is mounted on the moving mechanism, which is used to move the lower mold back and forth. The tire-retrieving mechanism is located in front of the lower mold and functions to pick up and place tires. During tire vulcanization, the tire blank is placed on the lower mold. Then, the lifting mechanism is opened, causing the upper mold to descend and rest on the lower mold, placing the tire blank between the two molds. An external steam delivery mechanism is then connected to a gas supply pipe, which delivers high-temperature steam into the vulcanizing bladder, causing it to expand and contact the inner wall of the tire blank. The heating plate on the upper mold is then turned on, heating the tire blank and vulcanizing it under high temperature and pressure. After vulcanization, the upper mold is raised using the lifting mechanism. Then, the valve on the exhaust pipe is opened, allowing the hot steam in the vulcanizing bladder to escape to the outside through the gas supply and exhaust pipes, causing the vulcanizing bladder to contract. Finally, the moving mechanism... The moving mechanism moves the lower mold forward to below the tire removal mechanism. Then, the tire blank is removed from the lower mold and placed on the tray by the tire removal mechanism. In this case, the lower mold and upper mold squeeze the outer wall of the tire blank, and the vulcanizing capsule squeezes the inner wall of the tire blank, so that both the inner and outer walls of the tire blank are subjected to pressure, and the pressure is uniform. After the tire blank is vulcanized, it can assist the workers to move the tire blank to the tray, avoid burns to the workers during the tire removal process, facilitate the handling of the tire blank, and has high practicality.

When adjusting the height of the upper mold, the hydraulic cylinder A is opened, and the hydraulic cylinder A adjusts the height of the upper mold through the push rod. This facilitates the adjustment of the height of the upper mold.

[0006] Preferably, the moving mechanism includes an electric slide rail A and a sliding block. The electric slide rail A is fixedly installed on the base plate, and the sliding block is installed on the electric slide rail A. The electric slide rail A is used to move the sliding block back and forth. The lower mold is fixedly installed on the upper end of the sliding block. After the tire blank is vulcanized, the upper mold is raised, and then the electric slide rail A is opened. The electric slide rail A drives the sliding block to move forward, thereby causing the lower mold to move the tire blank forward to below the tire removal mechanism. This facilitates the back and forth movement of the lower mold.

The electric three-jaw chuck is installed on the moving block through the height adjustment mechanism, which has the function of adjusting the height of the electric three-jaw chuck. The fixed frame B is fixedly installed on the support frame in the workshop. After the lower mold moves the tire blank to below the electric three-jaw chuck, the height adjustment mechanism is opened, causing the electric three-jaw chuck to descend and contact the upper part of the tire blank. Then, the tire blank is clamped and fixed by the electric three-jaw chuck. Then, the electric three-jaw chuck is raised, and then the electric slide rail B is opened, causing the moving block to move to the left. The moving block drives the height adjustment mechanism and the electric three-jaw chuck to move to the left above the tray. Then, the electric three-jaw chuck moves the tire blank down, causing the tire blank to contact the tray. Then, the electric three-jaw chuck is released, allowing the tire blank to fall onto the tray. This facilitates the picking and placing of the tire blank.

[0008] Preferably, the height adjustment mechanism includes a rotating mechanism, a hydraulic cylinder B, and a lifting rod. The hydraulic cylinder B is fixedly installed at the lower end of the moving block, the lifting rod is installed at the output end of the lower part of the hydraulic cylinder B, the rotating mechanism is installed on the lifting rod, and the electric three-jaw chuck is installed on the rotating mechanism.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] like Figures 1 to 5The present invention relates to a vulcanizing machine for producing uniformly pressurized rubber aircraft tires, comprising a lower mold 1, a vulcanizing bladder 2, an air supply pipe 3, an exhaust pipe 4, an upper mold 5, a base plate 6, a tray 7, a lifting mechanism, a moving mechanism, and a tire-removing mechanism. The vulcanizing bladder 2 is mounted on the lower mold 1. An air supply pipe 3 is provided on the vulcanizing bladder 2 and communicates with it. An exhaust pipe 4 is provided on the air supply pipe 3 and communicates with it. Valves are provided on both the air supply pipe 3 and the exhaust pipe 4. The upper mold 5 is located above the lower mold 1 and is equipped with multiple heating plates. The heating ends of the plates are all embedded in the inner wall of the upper mold 5. The upper mold 5 is mounted on a lifting mechanism, which is used to lift and lower the upper mold 5. The tray 7 is mounted on the base plate 6. The lower mold 1 is mounted on a moving mechanism, which is used to move the lower mold 1 back and forth. The tire-removing mechanism is located in front of the lower mold 1 and has the function of picking up and placing tires. When vulcanizing the tire blank 22, the tire blank 22 is placed on the lower mold 1. Then, the lifting mechanism is opened to lower the upper mold 5, so that the upper mold 5 is lowered onto the lower mold 1, and the tire blank 22 is placed between the upper mold 5 and the lower mold 1. Then, external steam is supplied. The feeding mechanism is connected to the air supply pipe 3, which then supplies high-temperature hot steam to the vulcanizing bladder 2, causing it to expand and contact the inner wall of the tire blank 22. The heating plate on the upper mold 5 is then opened, heating the tire blank 22 and causing it to vulcanize under high temperature and pressure. After vulcanization of the vulcanizing bladder 2 is complete, the upper mold 5 is raised via the lifting mechanism. Then, the valve on the exhaust pipe 4 is opened, allowing the hot steam in the vulcanizing bladder 2 to escape to the outside via the air supply pipe 3 and the exhaust pipe 4, causing the vulcanizing bladder 2 to contract. Finally, the mechanism moves... The mechanism moves the lower mold 1 forward below the tire removal mechanism, and then the tire blank 22 is removed from the lower mold 1 and placed on the tray 7 by the tire removal mechanism. In this case, the lower mold 1 and the upper mold 5 squeeze the outer wall of the tire blank 22, and the vulcanizing capsule 2 squeezes the inner wall of the tire blank 22, so that both the inner and outer walls of the tire blank 22 are subjected to pressure and the pressure is uniform. After the tire blank 22 is vulcanized, it can assist the staff to move the tire blank 22 to the tray 7, avoid burns to the staff during the tire removal process, facilitate the handling of the tire blank 22, and has high practicality.

The electric three-jaw chuck 15 is installed on the moving block 23 through the height adjustment mechanism, which has the function of adjusting the height of the electric three-jaw chuck 15. The fixed frame B13 is fixedly installed on the support frame of the workshop. After the lower mold 1 moves the tire blank 22 to below the electric three-jaw chuck 15, the height adjustment mechanism is opened. The adjustment mechanism lowers the electric three-jaw chuck 15, bringing it into contact with the upper part of the tire blank 22. The electric three-jaw chuck 15 then clamps and fixes the tire blank 22. The electric three-jaw chuck 15 is then raised, and the electric slide rail B14 is opened, causing the moving block 23 to move to the left. The moving block 23 drives the height adjustment mechanism and the electric three-jaw chuck 15 to move to the left above the tray 7. The electric three-jaw chuck 15 then lowers the tire blank 22, bringing it into contact with the tray 7. Finally, the electric three-jaw chuck 15 is released, allowing the tire blank 22 to fall onto the tray 7. This facilitates the loading and unloading of the tire blank 22.
