Flange is a disc-shaped part, which is most common in boiler and pipeline engineering. Flange is mainly used for pipeline connection. At the interface of the pipeline that needs to be connected, a flange is installed. Low-pressure pipelines can use threaded flanges, and welding flanges are used for pressures above 4 kg. Add a seal between the two flanges and then tighten them with bolts. Flanges of different pressures have different thicknesses and use different bolts. When water pumps and valves are connected to pipelines, parts of these equipment are also made into corresponding flange shapes, also known as flange connections. The connection parts that are closed at the periphery of two planes using bolts are generally called “flanges”, such as the connection of ventilation ducts. This type of parts can be called “flange parts”.
Flange is a device used for connection between pipes, flange molding machine manufacturers in the design of the flange, need to solve two basic problems: connecting elements with sufficient strength and stiffness; to ensure that the bolted connection sealing structure does not produce leakage (not exceeding the permissible leakage value) within the specified operating period, flange machinery, theoretically, flange connectors can be solved by calculating the strength of the flange connection, while the bolted flange connection sealing Performance is largely dependent on the material properties of the connecting elements and quality consciousness, manufacturing precision and assembly level.
The equipment for making flanges is called flange machine. When the flange machine makes flanges, the first thing to consider is the size specification of the flange, according to our needs to make the size selection, in general, we need to consider from several aspects, first of all, the thickness of the material, if it is too thin, the rolling will also have problems, if it is too thick, we need to choose the right flange machine. In addition to the flange material, flange diameter size is also what we need to pay attention to, too small, we can’t roll, big can be unlimited. Therefore, we can conclude that for the mean flange small is required, large is not required, I hope that when we roll the flange, choose the right flange machine.
Product features of flange forming machine:
1. The equipment adopts straight line angle forming and cutting off, single flange forming and cutting off.
2. It is mainly used for the outer roll rounding of angle iron, also can roll flat iron ring, round pipe ring, square pipe round ring, but need to order special roll.
3. According to different needs to replace the roll, can be rolled angle iron, flat iron, three rolls in the work of the roll gap can be adjusted to save materials.
4. Processing without front and rear end straight loss of material, high efficiency, reduce costs.
Working principle of automatic flange machine.
High-pressure oil output from the electric oil pump is sent into the working cylinder or motor through the high-pressure oil pipe, and the high-pressure oil pushes to persuade the plunger in the working cylinder or motor, generating thrust and torque, and bending the profile through the mold parts.
This product is widely used in fan. Bridge formwork. Chemical equipment. Cable wire frame. Mining explosion-proof switch. Centrifuge and other mechanical equipment industry applications. Also suitable for external processing. The flange forming machine is mainly used to roll all kinds of profiles, fans, bridge templates, chemical equipment, cable wire racks, mining explosion-proof switches, centrifuges and other machinery and equipment industry applications. Flange forming machine using three rollers on the mold will be a variety of profiles such as: flat steel, channel steel, round pipe or other shaped cross-section profiles rolled and bent into a certain curvature of the round, arc, spiral. The machine mold for the combination, change the combination can be applied to a variety of profiles.
