Yaokou, also known as bone reel machines, sewing bite, biting edge machine, duct Yaokou, duct reel bone machine. Is a versatile aircraft, mainly used for connecting plates and round duct connection closed The bite processing. various shapes of bone type manufactured to meet the duct. workpiece plate thickness of 0.4-1.5mm. all gears, shafts, rollers of the machine are made of high quality steel, heat rigorous process to ensure mechanical durability Duct production quality and stability, with easy installation, beautiful appearance, reasonable mechanical principles, mobile and flexible, easy operation and other characteristics, can meet the requirements of different users. Yaokou suitable for ventilation, air conditioning, purification and other means, according to the requirements, can be made into a variety of square, rectangular plate duct, a variety of sheet metal processing, duct production and other mechanized equipment indispensable.
Yaokou structure consists of three parts: the feed section; transmission parts; molding parts.
1, molded parts, mainly referring to host part of the core part of the roll. When the feed between the two pressure rollers excessive or enter the piece of metal, the hydraulic cylinder piston rod pressure overload, the pump will be shut down, the accumulator pressure change dampening effect, turn back to the oil spill, the piston rod displacement increasing the gap between the pressure roller so hard object by the pressure roller, the system pressure returned to normal, can protect the pressure roller is not damaged.
2, feeding part, is to achieve dosing to ensure uniform access to the material between rolls. Screw feed device by the electromagnetic speed motor drive pulley, worm reducer rotation will be pressure to force the material entered the inlet pressure Since the electromagnetic speed motor constant torque characteristics, when the pressure quantity and the amount of material equal to the desired host screw feeder, you can maintain a constant feed pressure to pellet quality and stability, such as excessive feeding, the feeding device The electrical overload, feed rate is too small is not a ball, so the operation of skilled technology is an important condition to ensure the normal work pressure the ball.
3, transmission parts, the main drive system are: a triangle with a motor - a reducer - an open gear - one rolls the host to provide power from the electromagnetic speed motor, the pulley, spur gear reducer, through the rod coupling. transmitted to the driving shaft. drive shaft and the driven shaft through the open gear to ensure synchronous operation. Passive bearing equipped with a hydraulic device behind the hydraulic protection device is a high-pressure pump oil into the cylinder, the piston displacement axial piston before the next head of the rod in the bearing housing pressure to meet production requirements.
