Description

Technical Field

[0001] The present invention relates to the technical field of segment mold pouring vibration, and specifically relates to an automatic docking device for air nozzles of an air-vibrated segment mold. Background Art

[0002] Currently, when pouring and vibrating segment molds, there are mainly two methods: air vibration and vibration motor vibration. In the former method, an air vibrator is installed on the mold, and in the latter method, it is installed on a fixed vibrating table to vibrate the mold at a fixed work station. The former has gradually occupied the market due to its low vibration noise, more uniform vibration force, and low failure rate.

[0003] As the market share of the attached air-vibrated segment mold increases, most segment manufacturers consider using air-vibrated segment molds when designing the segment construction plan. However, currently, when most manufacturers vibrate and pour the mold, a high-pressure air hose of a certain size is used as the connector between the mold air nozzle and the compressed air connection valve. Each time the mold arrives, the mold air nozzle is manually docked. After docking, a special tooling is also required to fix the connection joint to prevent the joint from falling off and hurting people during the vibration process. Therefore, this air nozzle docking method has certain safety hazards, and its operation efficiency is not high. Whether the air nozzle docking and installation is firm is also affected by human factors.

[0004] The invention patent application with the application number CN202210140179.5 discloses an automatic air connection device for a segment mold pneumatic vibrator, belonging to the technical field of air connection devices. An automatic air connection unit is composed of a cylinder, a shock absorber, a pipe connection rack, a floating support, and an air pipe insertion tube. The piston telescopic movement of the cylinder is sequentially transmitted through the shock absorber and the pipe connection rack to drive the air pipe insertion tube to move back and forth, so that the air pipe insertion tube is inserted into or pulled out from the air receiving port on the segment mold. The air receiving port distributes compressed air to the pneumatic vibrator, realizing automatic air connection and disconnection of the segment mold pneumatic vibrator, completely replacing manual operation, greatly reducing the labor intensity of workers, and avoiding the harm of noise to operators; moreover, the front end of the piston rod of the cylinder is connected to the pipe connection rack through a shock absorber, and a floating support structure is arranged at the front end of the device. The shock absorber has a compression and torsion effect, and the floating support has a floating fine-tuning effect under the elastic action of the spring. The combination of the two effectively ensures that the air pipe insertion tube can be directly opposite to the air receiving port and accurately inserted into the interface of the pneumatic vibrator. The technical solution of this application realizes automatic air connection and disconnection of segment mold vibration, but due to the instability of the air connection port position, the problem of alignment connection of the air connection port cannot be effectively solved by the technical solution of this application. Summary of the Invention

[0005] At present, for the operation of manually docking the nozzle quick connectors of the mold, the efficiency of manual docking of the nozzles is relatively low, and the personnel move the air pipes frequently. Long-term movement is extremely likely to cause the air pipes to fall off, crack, etc. If the automatic docking of the mold nozzles is realized, the above situations can be effectively avoided.

[0006] The invention purpose of the present invention is to provide an automatic docking device for the nozzle of the pneumatic vibration segment mold aiming at the above problems, including the equipment main body structure. A hydraulic pump station, a pump station motor and a hydraulic electric valve are installed at the lower part of the equipment main body structure, and a hydraulic cylinder is installed at the upper part of the equipment main body structure. A quick female joint is connected to the hydraulic cylinder. The quick female joint includes a first quick female joint and a second quick female joint. The second quick female joint is arranged at the tail of the hydraulic cylinder and is connected to the air supply hose; the first quick female joint is arranged at the end of the hydraulic cylinder. The hydraulic pump station, the pump station motor and the hydraulic electric valve provide power for the hydraulic cylinder to adjust the position of the first quick female joint to accurately align and connect with the quick male joint of the mold. The present invention realizes the automatic vibration operation of the mold after the segment mold reaches the pouring station, the device automatically completes the docking of the mold nozzles and completes the vibration, greatly improving the vibration efficiency of the segment mold and reducing the potential safety hazards.

[0007] The technical solution adopted by the present invention is as follows:

[0008] At present, the transfer of the mold on the assembly line is realized by a conveying roller path, and the movement of the mold is controlled by an automated program. After the mold travels to the pouring station and completes the positioning, the subsequent operation is to dock the nozzle joint of the mold. After the docking and installation, the pouring and vibration operation of the mold can be carried out. Combining with the docking method of the mold nozzles, all the existing mold nozzle joints adopt quick joints. After the mold arrives, the worker inserts the female joint connected to the hose into the male joint and locks the locking buckle to carry out the vibration operation of the mold; this application mainly improves the automatic alignment method and equipment structure of the nozzle after the segment mold arrives.

[0009] The present invention discloses an automatic docking device for the nozzle of the pneumatic vibration segment mold, including the equipment main body structure.

The hydraulic cylinder slides up, down, left and right on the cross slide table. When the hydraulic cylinder is forced to lift, the docking position of the hydraulic cylinder relative to the quick male joint of the mold is automatically adjusted through the cross slide table.

[0012] Further, a stress spring is arranged on the main structure of the equipment. The stress spring is arranged circumferentially along the guiding slide plate. When the hydraulic cylinder is disconnected from the quick female joint and the quick male joint of the mold, the stress spring drives the hydraulic cylinder to automatically return to the initial working position.

[0013] Further, the hydraulic cylinder includes a cylinder body. A tail connection thread is arranged at the tail of the cylinder body. The cylinder body is connected to the second quick female joint through the tail connection thread. An end connection thread is arranged at the end of the cylinder body.

[0014] Further, a hollow shaft piston rod is arranged at the end of the cylinder body. The end connection thread connects the first quick female joint and the hydraulic cylinder, and sealing is achieved by installing a sealing ring at the end.

[0015] Further, the first quick female joint is in the shape of a flared mouth. When the hydraulic cylinder lifts, the quick male joint of the mold is docked through the flared mouth-shaped first quick female joint.

The hydraulic pump station, the pump station motor, and the hydraulic electric valve provide power for the hydraulic cylinder to adjust the position of the first quick female joint to accurately align and connect with the quick male joint of the mold.

[0029] In this embodiment, a central hole is opened in the hydraulic cylinder to form a hollow shaft hydraulic cylinder with a hollow structure. The central hole of the hydraulic cylinder forms an air path conduction. The hydraulic cylinder is connected to the quick female joint and the quick male joint of the mold to realize the ventilation of the central hole of the hydraulic cylinder. Further, the hydraulic cylinder includes a cylinder block. A tail connection thread is provided at the tail of the cylinder block, and the cylinder block is connected to the second quick female joint through the tail connection thread; an end connection thread is provided at the end of the cylinder block, and the cylinder block is connected to the first quick female joint through the end connection thread.

[0030] In this embodiment, the hollow shaft hydraulic cylinder is the core component of the entire automatic docking device. The central hole of the hollow shaft is used for air path conduction. Both the end and the tail of the cylinder block are designed with connection threads for male and female joints. After the air path connection at the tail of the hydraulic cylinder is completed, by jacking up the hydraulic cylinder, the first quick female joint installed at the end is jacked up to the position of the quick male joint of the mold to realize the quick docking of the joints, and the air supply is automatically sealed through the sealing ring provided at the end. After the docking is completed, the air path can be conducted to carry out the mold pouring and vibration operation. This embodiment adopts the design of air path conduction of the hollow shaft hydraulic cylinder. By connecting the air path to the quick connection joint at the tail of the hollow shaft hydraulic cylinder, the female joint with a flared shape at the end automatically docks with the quick male joint of the mold, realizing the quick and automatic docking and sealing of the mold air nozzle.

[0031] In this embodiment, a hollow shaft piston rod is provided at the end of the cylinder block; the end connection thread connects the first quick female joint and the hydraulic cylinder, and the sealing is realized by installing a sealing ring at the end.

[0032] In this embodiment, the first quick female connector is in the shape of a flared mouth.

Through the guiding force generated during the lifting process, the hydraulic cylinder can achieve automatic and rapid adjustment in the up, down, left, and right directions on the slide rail. Further, in this embodiment, the first quick female connector is nitrided to improve the strength at the guiding friction position between it and the quick male connector of the mold, thereby extending its service life.

[0033] Embodiment 2

[0034] As Figures 1-4 shown, this embodiment provides an automatic docking device for the air nozzle of a pneumatic vibration segment mold, which includes a main equipment structure. A hydraulic pump station, a pump station motor, and a hydraulic electric valve are installed at the lower part of the main equipment structure, and a hydraulic cylinder is installed at the upper part of the main equipment structure. A quick female connector is connected to the hydraulic cylinder. The quick female connector includes a first quick female connector and a second quick female connector. The second quick female connector is arranged at the tail of the hydraulic cylinder and is connected to the air supply hose; the first quick female connector is arranged at the end of the hydraulic cylinder. The hydraulic pump station, the pump station motor, and the hydraulic electric valve provide power for the hydraulic cylinder to adjust the position of the first quick female connector to accurately align and connect with the quick male connector of the mold.

[0035] In this embodiment, in order to solve the problem that the error in the mold positioning process leads to inaccurate docking of the automatic docking air nozzle, a slide rail is installed on the main equipment structure, and the hydraulic cylinder is fixed as a whole by the slide rail. Preferably, a guiding slide plate is fixed on the main equipment structure through an HGH slide rail and a stress spring. During the process of the hydraulic cylinder docking the quick male connector of the mold through the first quick female connector in the shape of a flared mouth, due to the guiding force generated, the hydraulic cylinder can achieve automatic and rapid adjustment in the up, down, left, and right directions on the slide rail, thereby realizing the automatic and rapid accurate positioning of the air nozzle.

[0036] In this embodiment, preferably, the guiding slide plate and the slide rail form two sets of cross slide tables, and the hydraulic cylinder slides up, down, left, and right on the cross slide tables. During the process of the first quick female connector with a flared mouth at the front end of the hydraulic cylinder docking the quick male connector of the mold, due to a large error in the parking position of the segment mold, it is necessary to guide the first quick female connector during the docking process. By installing the hydraulic cylinder on the cross slide table that can slide up, down, left, and right, and utilizing the guiding force between the first quick female connector and the quick male connector of the mold, the position of the cylinder is adjusted, and then the quick and accurate positioning of the female connector and the male connector is realized. In this embodiment, by setting two sets of cross - intersecting guiding slide tables, the automatic guiding of the relative position of the central hole of the cylinder to the central hole of the mold air nozzle during the automatic docking of the air nozzle by the cylinder is realized, ensuring the sealing performance of the air nozzle after docking and the safety of the air circuit system during the vibration of the mold.

[0037] In this embodiment, in order to ensure that the hydraulic cylinder can return to the initial position after deviation, a stress spring is arranged on the main structure of the equipment. The stress spring is arranged along the circumferential direction of the guiding slide plate. The hydraulic cylinder is disconnected from the quick female joint and the quick male joint of the mold. The stress spring drives the hydraulic cylinder to automatically return to the initial working position.

[0038] Preferably, in this embodiment, the cross slide table adopts a spring prestress control setting scheme. Four groups of stress springs are arranged on the guiding slide plate where the hydraulic cylinder is installed. After the mold vibration is completed, the hydraulic cylinder is reset through the four groups of stress springs, and the automatic reset of the initial position of the hydraulic cylinder is completed, which is convenient for the next automatic docking vibration of the mold.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
