Fire damper making machines are widely used in construction engineering to manufacture products for ventilation, air conditioning and fire extinguishing systems. By mass-producing the dampers, production was greatly increased. Guarantee the progress of the project. Due to the high cost of welded fire valve frame, complex process, high requirements for workers and low yield. We adopt modular design...
Automatic pipe welding machines are used in industry to connect two pipe fittings. The welding process involves complex joining operations. The reproducibility of welding is one of the key parts of product manufacturing. Compared with manual pipe welding machine, automatic pipe welding machine welding speed is faster. In addition, they provide more consistent welding and fewer process and product ...
Our company has successfully developed and manufactured a fully automatic production line for fire damper frames. The fire damper production line series consists of functional components such as uncoiler, roll forming host, and fixed-length cutting. It can be combined according to customer requirements to meet the requirements of different types of valve bodies. In order to meet different producti...
There are many types of roll forming machines, which can be distinguished according to their structure. Commonly used are cantilever roll forming machines, double-end roll forming machines, standard roll forming machines, double-layer roll forming machines, Quick change roll forming machine. Let's take a look at their respective structural characteristics and what are their advantages and disadvan...
Cut to length machines are used for uncoiling, straightening, cutting to length and stacking sheet metal. Cut to length machines process metal coil rolls that come from metal mills. Metal coil rolls are unusable in the form that they are shipped in, which is why manufacturers value cut to length machines so highly. A cut to length machine offers automation that can make sure of accurate feeding, s...
Cut to length line is typically used for unwinding, straightening, measuring, cross-cutting rulers and stacking of a variety of materials, such as cold-rolled or hot-rolled carbon steel, tinplate, stainless steel, and other surface-coated metals. This series of production lines has an efficient automatic sizing function, which can trip a variety of different specifications of coils through unwindi...
Pipe welding machines are increasingly used in the construction industry, and some large factories have introduced pipe welding machines: for example, square pipe welding machines and pipe welding machines with different functions. Now welded pipe equipment has become one of the indispensable equipment in welding plants. In terms of application, high-frequency pipe welding machines are mainly used...
Design and selection of fire dampers produced by fire damper production lines The smoke and fire dampers are now analyzed in combination with the specific ventilation system: the air supply fans in the underground garage should be equipped with electric air volume control valves or fire control valves (automatically closed at 70°C). If the air supply system needs to be shared with the fire-fightin...
There are four points that need to be paid attention to in the production process of automatic pipe welding machine: 1. First of all, the elongation of the pipe is longer than that of manual welding. Generally, 4-5mm is better. If it is too long, the penetration depth of the weld will be reduced, and the weld will not be beautiful; if it is too short, undercut and nozzle damage will occur. and oth...
