METMAC Duct pittsburgh lock former, also known as duct seaming closing machine. It is a multi-functional machine type, mainly used for the Pittsburgh lock forming, drive cleat, seam cleat processing of rectangular duct connection and circular duct joint connection.
It can do other various types of joint for duct manufacturing. The thickness of the processed plate is 0.5-1.5mm. All gears, shafts, and rolls of the machine are made of high-quality steel. After strict heat treatment process, the machine is durable, stable in quality, easy to install and convenient in operation. The Pittsburgh lock former machine is suitable for the production of air ducts for ventilation, air conditioning, purification and other devices. According to requirements, it can be made into various square and rectangular galvanized steel air ducts. It is an indispensable mechanized equipment for various sheet metal processing and air duct production.
The structure of the Pittsburgh lock former machine is composed of three parts: feeding part; transmission part; forming part.
1. The forming part mainly refers to the main machine part, the core part is the roll. When there is too much feed between the two pressure rollers or the extrusion between the rollers.
2. The feeding part is mainly manual feeding, using the gap between the rolls to feed.
3. In the transmission part, the main transmission system is: a motor, a triangle belt, a reducer, an open gear, and a roller. The main engine is powered by an electromagnetic speed-regulating motor, which is transmitted to the driving shaft through a belt pulley, a cylindrical gear reducer, and a rod-pin coupling.
