Introduction of New Aluminum Solar PV Panel Frames

L-shaped closed steel frame (photovoltaic panel frame), using the design and simulation module of Copra software, showing the powerful design and accurate simulation analysis functions, improving the design efficiency, and reducing the error costs.

Parameter of New Aluminum Solar PV Panel Frames

Copra software provides a variety of board width calculation methods (such as standard formula and DIN6935, both methods are used in this case). According to the final product section, the initial feed board width is 155.49mm.

 

The surface of the feed strip is galvanized magnesium-aluminum coating, the yield strength is 365MPa, the tensile strength is 490MPa, the elongation is 16%, the Poisson’s ratio is 0.3, and the Young’s modulus is 210GPa.

The knurled design of New Aluminum Solar PV Panel Frames

The number of roll forming passes of this section is 41.

The software provides a variety of unfolding forming methods for corner unfolding. This section adopts two methods: constant length of neutral layer and fixed radius.

The software provides a convenient roll design-spreadsheet function, which can help engineers to quickly develop and modify the section.

The Roller flower rationality verification  of New Aluminum Solar PV Panel Frames

The software provides a rapid verification tool for the rationality of the roll pattern design. The state of the strip after each pass is shown in the figure, and the longitudinal strain of the edge of the strip is displayed in different colors when it passes through each pass.

 

 

The longitudinal strain value of each pass is displayed in the form of a bar chart, which is used to verify whether the forming angle and forming number of each corner are reasonable. As shown in the figure, the forming longitudinal strain of each pass meets the design requirements.

Roll Design of New Aluminum Solar PV Panel Frames

The software provides a variety of roll design and correction functions, which can quickly obtain the matching roll drawings, and can quickly export the drawings and roll weights. As shown in the figure, the blank width and diameter can be quickly obtained. The blank weight is about 414.63Kg.

 

The software can quickly convert the designed two-dimensional graphics into three-dimensional entities, and quickly check whether the arrangement of the rolls is reasonable and the forming characteristics of the sheet, as shown in the figure below.

Simulation of New Aluminum Solar PV Panel Frames

Through Copra software, design drawing files can be quickly converted into finite element models, and calculations can be submitted quickly, reducing the operation process from design to simulation.

Simulation Results of New Aluminum Solar PV Panel Frames

The software provides a cross-section comparison function, that is, the cross-section of the simulated strip passing through each pass is compared with the cross-section of each pass designed by the user. The picture shows the cross-section comparison of the 5th pass. The red curve is the cross-section of the simulated strip, the blue is the cross-section designed by the user, and the green is the cross-section of the simulated strip after rolling out of the roll.

Users can check the transverse flow of the strip, the springback of the strip after it rolls out of the roll, and the shape of the strip at each moment, and can measure the extension distance and springback angle of the strip. Through the cross-sectional comparison, it can be seen that the R angle at A rolls back out of the roll.

When the profile is rolled out of the last pass, the cross section of the simulated strip (red) is extracted and compared with the design section of the last pass (blue). By comparison, it can be seen that the profiles in area A are well formed and meet the design requirements; the profiles in area B are slightly deviated from the design due to the springback and the forming force of other parts; the profiles in area C are not ideally formed, because the profiles are in The lateral flow of material occurs during the molding process, so the size of the profile at this position has deviated from the design size before the C area is formed, and further optimization of the design is required.

When the profile is rolled out for the last pass, the front end of the feed is cut off, leaving the profile as shown in the figure, showing the Y-direction cloud map (thickness direction). It can be seen that the middle position of the profile (indicated by the arrow) is bulging. Since the diameter of the lower roll in all passes is fixed, the profile may be longitudinally squeezed when entering the roll. In the later optimization, the method of increasing the diameter of the lower roller can be used to keep the profile in a stretched state.

When the profile is rolled out for the last pass, the front end of the feed is cut off, and the thickness variation curve of the profile is extracted. As shown in the figure, the thickness of the corner area is reduced, and the specific size can be viewed in the longitudinal coordinate value.

Through the Copra software, the force of the rollers in each pass can be viewed (all passes, up and down, left and right and inclined roller axes, different directions). As shown in the figure, it is the force in the Y direction (thickness direction) of the roller under all passes, which is also the maximum force direction of the roller. It can be seen that when the profile passes through 31 passes, the lower roller is the most stressed, and the force value is about 0.58 tons. The user can judge whether the roll shaft diameter meets the design requirements.

The wear of the profile after passing through the rolls can be viewed through the Copra software.

Section Description

3 T Manual decoiler

1.This part can manually tighten or shrink the core, so that the loading and unloading of the roll is very convenient.

2.This device can tighten the stainless steel coil. Because the stainless steel coil is very narrow, the coil with a long outer diameter is easy to become loose during use. A longer tightening device can be customized for you to prevent the stainless steel coil from becoming loose , To prevent the interruption of the operation of the door frame equipment, causing danger!

3.The decoiler is equipped with a manual brake. Once a danger occurs during the operation of the equipment into the roll, the operation of the decoiler can be stopped immediately to prevent the occurrence of danger.

Roll forming system

1. The machine is equipped with lifting holes and has been reinforced. The loading and unloading of the machine is very easy, and the machine itself will not be damaged by loading and unloading the machine. As we all know, the machine is prone to loosening a part of the screw or violent packing during the loading and unloading process. The inevitable consequences of machine cracking, painting, bending, etc., will cause serious problems such as deviation and small sides after the machine is running.
2. The feed guide roller is made of Cr12 material and is chrome-plated to increase the hardness of the feed guide roller. Some manufacturers use other materials or paint, and there is no difference in appearance, but after a few months of use, the paint will be worn and dropped. , The original material is exposed, and it will rust or be damaged if used for a long time.
3. Several rows of such side rollers, also called vertical rollers, are added inside the forming machine. The function of this side roller is to prevent the sheet from deviating, and to make the small side of the sheet perfect, reduce the impact of small side springback, and consolidate Molding effect.
4. The machine uses 8.8 grade bolts, which have high tensile strength and yield strength, and have been boiled black, which has strong corrosion resistance. The service life can reach 10 to 15 years. The cost of a bolt is 2 to 3 for ordinary bolts. Double the price. If you use ordinary bolts and use them for a long time, the bolts are prone to loose or rust when the machine is running, which will cause inaccurate forming of the sheet or the machine will not run, damage and stop, which will hinder your business.

5.  The nuts for fixing the gantry wall panels are also boiled black and have high corrosion resistance. As we all know, when we adjust the machine or change the mold, we need to remove the nuts frequently. Once they are corroded and rusted, we need to replace the nuts. The cost is also very high, many manufacturers do not carry out this part of the process, our nuts are 2 to 3 times the price of ordinary nuts.

6.   The drum is made of Cr12 material, quenched and chrome plated. For galvanized materials, there are very high requirements on the rollers. Some manufacturers did not implement the correct process. In order to save costs, the chrome plating time is short or quenching is not performed, and sometimes only part of the roller is processed. As a result, the roller has a short service life and is easily damaged.

7.   The machine wall panel adopts a cast iron arch structure with a thickness of 28mm. This structure makes the machine run more stable.

8.Adopt Omron counter, this kind of counter has long service life and accurate automatic counting.

PLC control system

9.Manual touch screen, and all large screens are used. We use the Delta brand, which is easy to operate, fast and accurate, and can design a variety of parameters and functions.

10.For buttons, we usually use Schneider brand. Common electrical components have a short service life. Once broken, it is difficult to find matching repairs. However, Schneider is a global warranty and the after-sales service is very convenient.

11.Generally, the electric cabinet box in the factory is painted. After a long time, the paint is easy to fall off. The electric cabinet box we use is painted. For a humid environment, it has a long service life and will not lose the paint. Our electric cabinet box shell is more Thicker, reflected in the weight, and stronger.

12. The electric cabinet is equipped with an intelligent heat dissipation system, which can run for a long time and has a long service life. The electrical materials are also internationally renowned brands. The original electrical appliances can be purchased as accessories abroad, which are very durable and convenient.
13. Using this kind of aviation plug for wiring makes it easy to connect the electricity to the main engine, petrol station, and motor, so we won’t have installation and after-sales problems, and this wiring method is very safe.

Hydraulic oil pump station

14.  The hydraulic oil station is equipped with an air-cooled device, and the machine can run for multiple hours without stopping, which will continue to last for your business and have a long service life.

15.  The solenoid valve adopts the Japanese Yuken brand, which is durable and not easy to damage.

16.  The oil pump adopts new technology and produces very little noise.

17.  The tank is thickened and uses a large fuel tank to provide strong power for the operation of the machine, which is 2 to 3 times the price of an ordinary fuel tank. The ordinary fuel tank is prone to oil leakage and cannot be started. This is very durable.

cutting system

18.The cutting blade is made of Cr12 material and quenched. It has strong wear resistance, stability, compressive strength and other characteristics. Will not bend or crack after long time use. Galvanized material has better cutting effect and is very durable.

product collect table

19.This kind of material receiving rack can be manually packaged while receiving materials, which is convenient to operate and practical and stable.
