Between the decline in factory orders and rising labor costs and energy companies that use metal plate in their manufacturing processes find their profit margins increasingly pinched.
However, still need to manufacturers investing in new production equipment - whether to replace obsolete equipment or to take advantage of new business opportunities - in order to survive in the competition.
Must conduct evaluations manufacturers cautious when evaluating the addition of new facilities for rolling plate. Debt capital is always available for the purchase of new machines, but to repay the loan will be no satisfactory return on investment unless the equipment adds value to the production. Unfortunately, many buyers end up buying equipment that does not have the ability and flexibility to meet production volume and endurance, because they simply do not understand all the available options and considerations.
In an effort to help manufacturers plate rolling process improvement, and suggests 5 key factors to select a plate bending machine suitable.
1. Factor in the properties of materials that rolled
Even if the graphics call to the plate rolling down to the same dimensions, and stronger materials require rolling machine much higher rated. In the absence of these considerations, it will result in defects in manufacturing and you will end up with excessive scrap.
Today much stronger than steel and requires more force to bend.These different pressures require steel to roll.
Character must be linked to a bright and return with the client application to correctly determine the specifications panel roll. This is particularly important because the steel properties has changed dramatically over the past two decades. What was known as Mild Steel no longer exists.
2. Working with an equipment dealer who is willing to discuss your specific needs rolling plates
Customers need to know the right questions to ask to get the right answers. Each product faces unique challenges, and the systematic interrogation of a smart salesperson to determine exactly what equipment will work best for the process.
You should also carefully consider manufacturers whether they want to publish a conical shape or equivalent to enjoy a wider market. Hydraulically controlled four-cylinder machines are ideal for this type of work by eliminating the scars surface, which reduces the need for grinding roll (bullnosing) on the edge of the small diameter cone.
And checks still hold tapered accurate through features such as torsion bar parallel, rather than electronic systems or systems relative values that maintain the balance is just a theory. Limited parallelism allowed to set the device to conical tent complete and return at the same time in only five seconds.
Customers need to discuss issues such as internal diameters, and the type of material, and endurance desired shape of the final product. For example, some products, such as those found in the pressure vessel industry, requiring a maximum of 1% of out of round or diameters are flawed. Panel can be used rotary power is low, a lot of the gun to make the impact of such products useless quickly erase any profit potential.
Plate Rolling corresponding to the specific needs of the product needs to take care of. It is imperative that you are working with an agent ready to sit with you and discuss the specific needs of your business. There are many issues that must be addressed, many purchasing managers could not provide.
3. Stay within the optimum operating parameters of the machine
It is advisable to determine the equipment manufactures and workload represents the largest fish. Then, (company) to provide a machine camber to these specifications, and preserve the value of production hours and the elimination of large amounts of waste.
And usually convex rolling machines quality of at least 50 percent of the nominal value of the whole machine. Thus, a convex 1 - inch roll 1/2-inch close to the edge of the plate perfection.
May, regardless of this fact is important cause outside the specifications of the product that the customer does not accept. The most common problems arise when rollers attempt to push the boundaries of their top of the roll. If you were to return to the panel 5/8-inch low-grade machine 1 inch nominal effect barrel is likely to happen. This may or may not be an acceptable margin of error.
However, when approaching the plate thickness upper end of the classification of the device, while severe defects may occur. Unless corrected with chips, and it will not be salable. On the contrary, when the material is very thin rolled through a rated very thick plate, and the final product can approach the center of the two sides. Again, time is needed to correct this timing "hourglass" effect.
4. Consider carefully bending diameters
Tightening diameter, high pressure bending. In cases in which the material is returned thick internal diameters of proof (ID), and Qatar can upper roller device and arrange to make the difference between a product that cylindrical edges meet and that do not close.
In general, most machines can roll plate 1 1/2 times the nominal diameter greater. Thus, given a roll of 10-inch diameters upper inner diameter and tight at the time and could get 15 inches. However, new machines include evidence of planets able to keep the area around 50 percent more plaque pressure on the steering wheel during the rolling process, and thus achieve ratios of 1.1 times the diameter of upper roller. This creates an advantage of 30 per cent reduced diameters.
All machines make accurate measurements to 50 per cent of the nominal full. Therefore, the device can be given roller Engineering 3/8-inch 1.1 with 10 - inch roll roll top panel always 3/16-inch barrel ID 11 - inch flawlessly.
5. Includes both sides and elbows vertical supports to prevent unwanted
Requires adequate support rollers carry all horizontal and vertical, as provided by the manufacturer of the device panel rolling. Once hired, plate rolling becomes the work of one man instead of two. This frees valuable manpower that can be redirected to other jobs.
Through the deployment of a cylinder, when the inner diameter is more than 200 times greater than the thickness of the material, and the weight of the material becomes sufficient to bend the cylinder to eject the upper roller, and away from the device. Without adequate support, which led to unwanted radiation.
Buy a machine with both sides vertical and roller supports easily solves this attempt to skimp manufacturers problem.Some auxiliary equipment through the use of the Mediterranean "improvised" such as crane or forklift. However, this shortcut linking the use of equipment that could be used better elsewhere. Because it can not adequately support the material may still show unexpected turns.
