Description

Technical Field

[0001] The invention relates to the technical field of hydraulic hose processing, in particular to a hydraulic hose steam vulcanization device and an operating method thereof. Background Art

[0002] In order to make the rubber structure more stable during the production process of hydraulic hoses, the hydraulic hoses need to be vulcanized. The vulcanization process of the hydraulic hoses needs to be carried out in a vulcanizing equipment.

[0003] When the existing vulcanization equipment is performing steam vulcanization of hydraulic hoses, a water film will be generated on the surface of the rubber material during the vulcanization process. The water film can prevent the vulcanization gas from contacting the rubber, thereby reducing the reaction efficiency of the vulcanization gas and the hydraulic hose. On the other hand, most hydraulic hoses are horizontal structures, and steam is sprayed on the hydraulic hose from bottom to top, so that the lower side of the hydraulic hose is sufficiently vulcanized while the upper side is insufficiently vulcanized. Moreover, the inner wall of the hydraulic hose is not easy to be contacted by steam, resulting in uneven vulcanization of the hydraulic hose, thereby reducing the vulcanization quality of the hydraulic hose.

[0004] For example, a hydraulic hose production vulcanization device disclosed in announcement number CN116352935A fixes the hose by means of a spiral fixation method, and mentions the influence of water droplets generated during the vulcanization process on the vulcanization reaction. This solution uses vibration to make the water droplets passively slide or fall by gravity, thereby solving the technical problem that the water film reduces the low efficiency of the reaction between the sulfide gas and the hydraulic hose. However, there is still the problem of uneven vulcanization of the hydraulic hose.

[0005] Based on this, the applicant proposes a hydraulic hose steam vulcanization equipment and its operation method Summary of the invention

The rotating gear is meshed and connected with one side of a bearing toothed disc, and the other side of the bearing toothed disc is meshed and connected with a fixed gear ring.

7. The hydraulic hose steam vulcanization equipment according to claim 1 or 6, characterized in that: The fastening structure in the bearing groove on the bearing toothed disc includes a fastening block, and a supporting structure is movably arranged on the bearing toothed disc, a fixing groove is arranged on the bearing toothed disc on the inner wall of the bearing groove, the fastening block is placed in the bearing groove, a spring is arranged on the outer side of the fastening block, and one end of the spring is inserted into the fixing groove.

8. The hydraulic hose steam vulcanization equipment according to claim 7, characterized in that: The inner surface of the fastening block is arranged as an arc-shaped structure.

9. The hydraulic hose steam vulcanization equipment according to claim 7, characterized in that: The supporting structure includes a fixing rod, the top end of which is movably mounted on the bearing gear disc. The fixing rod is arranged as a structure that can be replaced from the bearing gear disc. A supporting rod is arranged at the bottom end of the fixing rod, and the distribution of the supporting rod on the fixing rod is consistent with the distribution of the bearing groove on the bearing gear disc.

10. An operating method applicable to the hydraulic hose steam vulcanization equipment as claimed in claim 1, characterized in that: The described operating method adopts the following steps: First, check whether the circuit of the hydraulic hose steam vulcanization equipment is normal, and check whether the steam pump, hydraulic cylinder, motor and fan can work normally; Second, according to the size of the hydraulic hose to be steam-vulcanized, select a fixing rod with a width smaller than the inner diameter of the hydraulic hose, install the top of the fixing rod on the load-bearing toothed disc, insert the top of the hydraulic hose into the load-bearing groove, and place the bottom of the hydraulic hose on the fixing rod; Third, start the hydraulic cylinder. The hydraulic cylinder and piston rod push the connecting plate down. The connecting plate drives the fixed gear ring and the load-bearing gear plate to descend, driving the hydraulic hose in the load-bearing groove into the vulcanizer. The sealing ring on the connecting plate is inserted into the sealing groove at the top of the vulcanizer to seal the vulcanizer. Fourth, start the steam pump, which blows steam into the interlayer of the vulcanizer through the steam pipe, and sprays the steam into the vulcanizer through the steam spray pipe to steam-vulcanize the hydraulic hose placed on the load-bearing gear disc; Fifth, start the motor, the motor drives the transmission shaft and the rotating gear on the transmission shaft to rotate, the rotating gear drives the load-bearing gear plate to rotate on the fixed gear ring, so that the load-bearing gear plate drives the hydraulic hose to rotate in the vulcanization tank, and the hydraulic hose is vulcanized; Sixth, start the fan, the fan will make the airflow in the vulcanizer carry steam and flow into the ventilation chamber 1 through the air inlet pipe, the airflow and steam in the ventilation chamber 1 will enter the ventilation chamber 2 on the fixed gear ring, and return to the vulcanizer through the exhaust pipe, so that the airflow and steam will circulate in the vulcanizer, and the steam in the upward flow process will enter the hydraulic hose, and the inner wall of the hydraulic hose will be vulcanized by steam; Seventh, after the steam vulcanization of the hydraulic hose is completed, turn off the fan, steam pump, and motor, start the hydraulic cylinder, and the hydraulic cylinder and piston rod drive the connecting plate to rise. The connecting plate drives the bearing gear plate and the steam-vulcanized hydraulic hose to move upward and move it out of the vulcanization tank. Remove the bottom end of the hydraulic hose from the support rod, take out the hydraulic hose from the bearing groove, complete the hydraulic hose, clean the impurities generated during the steam vulcanization of the hydraulic hose, and cut off the power supply.
