Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing, in particular to a hot-dip galvanizing pneumatic clutch centrifuge. Background Art

[0002] The currently used galvanizing technologies are mainly divided into electroplating and hot-dip galvanizing. Electro-galvanized coatings are thin and the zinc layer structure is not dense, so the durability is relatively low. Hot-dip galvanized coatings are thick, the zinc layer structure is dense, and the durability is relatively high, so it is widely used. Hot-dip galvanizing generally involves adding zinc ingots into a fixed galvanizing furnace, using gas or electricity to heat the galvanizing furnace to melt the zinc into a liquid state, then immersing the workpiece to be galvanized in the zinc liquid, taking out the workpiece after staying for a period of time, and cooling and forming it after removing the excess zinc liquid. The centrifuge is very commonly used during the zinc removal process. The main method is to spin off the excess zinc liquid on the surface of the parts by rotating centrifugally during hot-dip galvanizing production.

[0029] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with the drawings and specific embodiments.

[0030] As Figures 1 to 3 shown, a hot-dip galvanized pneumatic clutch centrifuge proposed by the present utility model includes a support unit, which has an installation space for providing support and fixation; a centrifugal unit, which is arranged on the support frame and is used for centrifuging the zinc liquid on the surface of the parts. During use, the parts to be hot-dip galvanized are placed in the centrifugal unit, and the rotation speed and angle of the centrifugal unit are adjusted to meet the specific requirements of the parts. Then the centrifugal unit is started to make it rotate at high speed to centrifuge the zinc liquid on the surface of the parts; a braking unit, which cooperates with the centrifugal unit and is used for braking the centrifugal unit to control the working state of the centrifugal unit. When it is necessary to stop the operation of the centrifugal unit, the braking unit will receive a control signal and start immediately, and make the centrifugal unit decelerate and stop quickly through friction or other mechanisms; a gear unit, the first end of which is connected to the centrifugal unit, and the power is transmitted to the centrifugal unit through the gear unit to drive the centrifugal unit to operate. During operation, the gear unit will maintain a stable transmission ratio and transmission efficiency to ensure that the centrifugal unit can operate at the set speed and angle; a transmission unit, the output end of which is connected to the gear unit, and the transmission unit is used for providing driving force. Before starting the centrifuge, first start the transmission unit and adjust it to the appropriate rotation speed and power. Then the transmission unit transmits the power to the centrifugal unit through the gear unit to drive it to start operating.

[0031] This centrifuge can meet the maximum centrifugal load of 1300KG in the field of hot-dip galvanizing centrifugal hot-dip galvanizing (clutch and brake torque range: 1NM - 13000NM), filling the blank of the load of the domestic clutch and brake centrifuge market. Under the load of 13000NM of the clutch and brake torque, and the rotational speed is high at 1 - 1000 r / min (revolutions per minute), the clutch and brake can be switched within 1 second: when the clutch starts, it only takes 0.5 seconds to reach a rotational speed of 1000 revolutions per minute from the "stop" state; when the clutch ends and the brake starts, it only takes 0.5 seconds to go from a rotational speed of 1000 revolutions per minute to the "stop" state.

[0032] In this embodiment, the support unit includes a support frame. A protective cover is provided on the support frame. The protective cover is hinged to the support frame. The protective cover is connected to the driving member, and the driving member can drive the protective cover to move, so as to facilitate discharging. The support frame is made of high-strength materials and can withstand the huge centrifugal force and vibration generated during the high-speed operation of the centrifuge, ensuring the stability of the entire device. A reasonable spatial layout is designed inside the support frame for accurately accommodating each component of the centrifuge, including the centrifugal unit, transmission unit, gear unit, and braking unit, etc., which not only ensures the close cooperation between components.

[0033] In this embodiment, the centrifugal unit includes a bearing seat. The bearing seat is arranged on a fixing plate, and the bearing seat is installed on the support frame through the fixing plate; a centrifugal shaft, one end of the centrifugal shaft is arranged on the bearing seat, and the other end of the centrifugal shaft is provided with a centrifugal component for installation. When the centrifugal shaft rotates, the centrifugal component will rotate accordingly, generating centrifugal force to perform centrifugal treatment on the zinc liquid on the surface of the part.

[0034] In this embodiment, the braking unit adopts a pneumatic clutch brake. The braking unit realizes the functions of clutch and brake through pneumatic drive. The structure and working principle of the braking unit are prior arts. To avoid text bloat, they are not described here. Preferably, this machine adopts a pneumatic clutch brake, which has better heat resistance, wear resistance, and dust resistance than an electromagnetic clutch brake.

[0035] In this embodiment, the gear unit includes a reversing gear set. Preferably, the reversing gear set uses helical gears. Compared with bevel gears, the gearbox design of helical gears can be more compact. The helical gear teeth of helical gears can withstand greater transmission forces, so they can transmit greater power. Helical gear reducers usually have high-precision transmission performance, and the transmitted torque and speed are stable and reliable. The first end of the reversing gear is connected to the power output end of the transmission unit, and the second end of the reversing gear is connected to the centrifugal unit. The driving force of the transmission unit is transmitted to the centrifugal unit through the reversing gear set. First, start the transmission unit to generate a driving force and transmit it to the reversing gear set. After receiving the driving force, the reversing gear set realizes the reversal of power through internal gear meshing and transmits the reversed driving force to the centrifugal unit. After receiving the driving force from the reversing gear set, the centrifugal unit starts to operate in a predetermined direction and speed to perform centrifugal treatment on the zinc liquid on the surface of the part.

[0036] In this embodiment, the transmission unit includes a transmission motor for providing a driving force. The output end of the transmission motor is connected to the gear unit through a transmission mechanism, and the transmission motor can drive the gear unit to operate. The transmission motor uses a servo motor or a stepper motor.

[0037] The usage process and principle of the present utility model are as follows: Place the parts to be hot-dip galvanized in the centrifugal unit, and adjust the speed and angle of the centrifugal unit according to the specific requirements of the parts; Start the transmission motor and adjust it to an appropriate speed and power. The transmission motor transmits the power to the gear unit through the transmission mechanism; After receiving the driving force of the transmission unit, the gear unit reverses the power through the reversing gear set and transmits it to the centrifugal unit. The centrifugal unit starts to operate in a predetermined direction and speed to perform centrifugal treatment on the zinc liquid on the surface of the part; During the centrifugal treatment process, monitor and adjust the speed and angle of the centrifugal unit in real time as needed to ensure the treatment effect; When it is necessary to stop the centrifugal treatment, the braking unit receives the control signal and starts quickly, and the centrifugal unit is quickly decelerated and stopped through the pneumatic clutch brake; After the centrifugal treatment is completed, perform the discharging operation through the movable protective cover, and regularly maintain and inspect the equipment to ensure its long-term stable operation.
