bending machine

When it comes to metal fabrication equipment, you may have heard of an angle roll bending machine. Some may refer to it as a section bending machine, but its purpose is still the same - form raw pieces of metal into desired shapes and sizes. If you have ever seen an angle roll bending machine, you would agree that most are constructed in a vertical steel frame. It is common that the bending portion of the machine is located on one side, with the power and drive of the machine on the opposite side. This writing is intended to educate and help the purchaser of Angle Bending Machines to ask the right questions when considering a purchase. Small units are powered by an electric motor with a reducer. The power transmission is accomplished by gear trains and or chains / sprockets Automatic Bending Machines. These are units used in small job shops and rod iron fabricating establishments. The new generation of the section bending machines is powered by hydraulic systems. These are used for bending from the smallest bars to very large wide flanged structural beams. The large hydraulic units have a double pump hydraulic system, with one providing the flow for the rotation of the rolls and the other for the extension and retraction of hydraulic cylinders attached to arms carrying the bending rolls. Some designs use one main hydraulic motor, usually mounted to an epicyclical in-line reduction gear, which imparts rotation to all three rolls. Another variation is each roll having its individual hydraulic motor/ reduction box combination directly driving it. The Bending Process: There are some terms used in the industry describing the capacities of Section Bending Machines and the process used, which the purchaser should become familiar with. Square and rectangular rods, round rods, square and rectangular tubing, round tubing, standard pipe, equal leg and unequal leg angles, "C" and "MC" channel, "S" and "WF" beams, "T" bars ...these are sections which can be rolled on section bending machines. "Leg out" means the leg of a section, like in angles will stick outward from the ring formed in a radial direction. "Leg in" means the leg of a section, like in angles will stick inward from the ring formed in a radial direction toward the center of the ring. "Leg out" is also known as "Easy way" and "Leg in "Hard way" There are exceptions to this terminology when it comes to channels, whereby one can bend a channel leg in, leg out and the hard way when bent on its side. Bending of round sections, pipes and round tubing require special tooling other than what is usually provided standard with section bending machines. In special cases with square and rectangular tubing where the wall thickness is low...the manufacturer should be consulted as to whether special all section enveloping tooling is required to avoid the section from collapsing under the bending forces. Bending Channels, S beams and WF beams the hard way, present a special challenge because the force of bending would sometimes collapse the web connecting the flanges. Most manufacturers of heavy section bending machines offer what is called a "Traction Tool", which holds the section back and supports the web so as to avoid collapse.

And Belgium LM series PLC in Hydraulic Bending Machine

1 Introduction Based Servo Motor CNC bending machine direct drive technology is the nineties developed high-tech, advanced manufacturing technology are cutting edge. Its research and development efforts for improving the general performance of domestically produced equipment, and to break foreign monopoly position in this technology is important. With PLC And touch screen technology, the application of the bending machine have been developed rapidly for the bending machine control system provides new ideas, new methods, but also for the improvement of production efficiency, productivity and living standards of humanity on the of great significance to improve. PLC and touch screen are used to open, for the bending machine flexibility and innovative control method provides the basis. 2 hydraulic press brake description 2.1 hydraulic press brake equipment structure Hydraulic press brake equipment form shown in Figure 1, is structured by frame, Foot switch , Bending angle and positioning mechanism, the level gauge positioning mechanism, bending under the pressure of institutions and electric control system, etc.. Bending angle positioning mechanism by the servo motor and chain drive mechanism composed of the bending angle can be fine-tuned according to the setting or the automatic height adjustment Bending Machines to ensure a high degree of positioning accuracy. Level gauge body from the servo motor and lead screw drive bodies, the width of the workpiece positioning for bending can be fine-tuned positioning can automatically locate, continuous bending can be automatically selected for multi-step, in turn achieve the positioning of multiple locations bending. Bending under the pressure of a hydraulic mechanism, in cooperation with foot switch can be inching, single and continuous three kinds of working conditions. 2.2 hydraulic press brake work process Bending machine work can be divided into inching. single and continuous three kinds of work. Point fixed: Select the operation to move the stalls, depresses the pedal slowly forward, bending under the pressure of auto body under pressure, hitting the next Travel switch Stop under pressure; under pressure into the process of slow foot loose and stopped running in the current location; under the pressure of the return process depresses the pedal, bending under the pressure to voluntarily return happens to stop the return trip; return process release the pedal return, stop return in the current location. Single: to set the holding time, unloading time, the level gauge into the retreat distance, adjust the level of gauge position; select a single operation stalls, bending under the pressure of body position switch is not on the trip, the first automatically switch back to the travel position; depresses the pedal slowly forward, bending under the pressure, under pressure to adopt voluntary; touch next trip switch, level gauge body set back distance, while automatic packing; holding time to unload automatically pressure, pressure relief agencies time to automatically return bend under pressure, while the level gauge body automatically advance to set distance; run into travel switch, single-end bending action. Continuous (process step): (1) to set the holding time, unloading time, the level of advance and retreat from the gauge, adjust the level of gauge position. ut

An overview of Hoover Washing Machines

The Hoover washing machine brand is very recognizable in Britain, Australia, and also the United States. They are known for their reliability, monetary value, and the vast range of different models to meet practically everyone's needs. On top of that, during the last 15 or so years, Hoover has changed their manufacturing strategy to save energy and water as well. Any Hoover washing machines are developed to meet rigorous and high standards. 10 kg, 9 kg, 8 kg Load Models Bending Machines Currently, the dynamic Hoover model range consists of 4 different versions that all have a 10 kg load capacity, 3 with a 9 kg capacity, and another 4 with an 8 kg capacity. The particular models were all developed for a customer base who need a large load capacity (perhaps large families), or maybe the coach of a football team. However, Hoover can very cleverly made sure that the outer size is still on par with some of the smaller machines, while just increasing the drum sizes within to create extra capacity.2 of the 10 kg models also have an extra energy conserving feature in that steam technology has been added in order to increase the water temperature to around 60 C. Most of the machines will never heat to above 40 C for the sake of energy conservation, however. Optima, one of the Hoovers premium lines, comes equipped with a six and seven kg load capacity total. This particular range is idea for anyone who needs to save some space but without having to downsize to a traditional 5 kg machine, which is significantly smaller in size. 2 of the 7 kg machines have been manufactured as "slim depth" for anyone who might have unusual space in which they need to fit the washer. The Optima range of washers usually offers a 20% increase in load capacity when compared to the 5 kg machines. Many hoover models come in the form of a washer and dryer combo model. This is extremely helpful when space is scare and there is no extra room for a dryer. Some customers of Hoover find it is of great value to get this combination because of the cost of a washer and dryer combo is significantly less than buying both separately. This is the dominating models of the Hoover washing machines. It is well designed and fits under bench tops, and provides the ideal energy conservation that many people desire. They are also well known for their excellent water conservation, conserving far less water than the top loading designs. Top Loaders These were primarily designed for those who just have a preference for this style. They also are very helpful to people that have a difficulty in bending over to use the front loading models. Hoover washing machines well cater to a diverse need of customers, but the bottom line when choosing a Hoover machine is always it's reliability, longevity, ease of repair and obtaining parts. These are going to be the features which will always lead to the best value in money in the long run. Additionally, the energy saving features you see make Hoover the leading brand, as usual.
