Why sheet metal parts need to be leveled

 If the sheet metal part is flat and stress free, the subsequent processing will be very smooth. Of course, to achieve this ideal effect, the sheet metal parts must be leveled. In this article, we will list 12 reasons why it is worth adding leveling.

  1. The sheet metal parts are of poor quality

At present, steel is more scarce than ever before. What if the warpage of the received sheet metal parts is far beyond the allowable tolerance? Returning materials can not solve the problem, because there is no material in hand, why processing? At this time, one of the most effective solutions is to flatten the sheet metal. The plate leveler flattens the bent plate, so the tolerance returns to the correct range.

  1. The customer complained that the sheet metal parts were seriously deformed

The stamped parts will be deformed, and the parts processed by thermal cutting processes such as laser cutting, plasma cutting and flame cutting are no exception. The reason is that processing releases the internal stress of the material. The deformation produced in the stamping process or the thermal effect in the cutting process aggravates the deformation of the material. Although the deformation is caused by the process, this does not mean that the customer will accept the deformed parts. One remedy: the MAHATMA leveler can level bent parts in seconds.

  1. Angle error often occurs after bending

Angle error after bending? This may be due to materials. Because the plate often has its own internal stress, although it is not visible to the naked eye and difficult to measure. If the springback during bending is different from the expected value, it may be caused by internal stress. Leveling can also help solve this problem. Leveling treatment can not only level the bent plate, but also reduce the internal stress of the plate to the greatest extent. This is conducive to all subsequent processing and allows you to obtain stable processing results. So as to reduce the defective rate, reduce the cost and improve the efficiency.

  1. The adjustment time of welding operation area is too long

Are there parts piled up in front of the welding operation area because the adjustment time of the actual operation is longer than planned? This may also be because the internal stress of sheet metal parts slows down the operation speed of employees. If the sheet metal parts cannot be clamped smoothly in the fixture as required, it will take time to make unnecessary adjustments. If the sheet metal parts sent for welding have been leveled, the welding speed will be much faster.

  1. The components after welding must be reworked

There seems to be no problem before welding, but the result after welding is unexpected! If the machining result does not meet the tolerance requirements, it must be reworked. Welded components are also affected by built-in internal stresses: invisible, but still present. The heat during welding aggravates the deformation and exceeds the tolerance limit. Therefore, it is best to carry out leveling treatment before welding to eliminate internal stress to the greatest extent.

  1. Tolerance accumulation exceeds the limit

In the processing process, each tolerance is qualified, but it is found that the tolerance is obviously unqualified after welding. One reason may be that each machining is too close to the tolerance limits of its process. Finally, the sum exceeds the allowable tolerance range. Therefore, it is best to produce as accurately as possible from the beginning. If the sheet metal is leveled, it is not difficult to do this.

  1. Quality problems of finished products

Even if the finished product looks good, the inner sheet metal parts may still have internal stress. Depending on the load on the component, the internal stress will be released at a later stage – which may damage the finished product. However, the quality problems complained by customers can be solved by flattening the parts.

  1. The stability of the shape of parts is affected

The setting of laser cutting machine is completely correct; Stamping abrasives are no problem. However, the shape of parts does not have its due stability. The internal stress of sheet metal can also be the reason. Therefore, it is best to carry out leveling treatment first to prevent trouble.

  1. The service life of the die is too short

Molds are expensive. They are even more annoying when they are used for a shorter time than expected. However, this can be avoided: compared with the sheet metal with large internal stress, the loss of the flattened sheet metal to the die is smaller. The most important thing is that there are fewer mold failures. Therefore, leveling treatment can improve productivity.

  1. The press faces the problem of increasing production capacity

The more strokes of the press, the more parts will be punched out. This can improve its productivity and economic benefits. But just setting a higher number of strokes on the machine is not enough. If the process is not further adjusted, there is a risk of damage to the mold or parts. One way to adjust the process is to use leveled materials. In this way, the number of strokes of the press can be increased – thus increasing the output.

  1. Too many rejected products are rejected by the full-automatic welding machine

Automatic welding machines are extremely strict in tolerance requirements. If the tolerance is too large, it will be classified as a rejected component. This in turn reduces the economy of the fully automatic welding machine. However, if the parts are leveled before being sent to the welding machine, their production capacity can be really fully utilized.

  1. The ejected sheet metal will damage the laser head

In the process of laser cutting, sometimes the internal stress of sheet metal will be released. At this time, if a cutting piece suddenly jumps up and pops up, it is likely to hit or even damage the laser head, resulting in subsequent unnecessary losses. In order to prevent the accident, the sheet metal parts should be leveled first.

Supplementary tips

To flatten sheet metal parts or plates, you do not have to purchase a flattening machine, but you can also choose to flatten outsourcing processing services. Mahatma processing suppliers can provide you with fast processing services: immediately understand the manufacturer’s requirements for sheet metal; Coordinate and determine the necessary tolerances and related workload and costs; It can also be responsible for arranging logistics and ensuring that there is no transportation damage or additional pollution.

PLATE LEVELING MACHINE

 Function of Leveling machine        Under the condition of large elastic-plstic bending, no mater how different the original bending degree, the CNC Sheet leveling machine uses the "Bauschinger effect" of the material to bend the plate repeatedly, gradually reduce the bending deflection, and gradually change the origina curvature into a single curvature, and finally level it to achieve the leveling accuracy required by the process.       After a series of alternating bending, the sheet metal is controlled by the motor and the PLC to accurately control the lower pressure of each leveling drum,elminating the internal stress, and fundamentally solving the unsatisfactory leveling effect caused by the different stress in each part of the sheet metal, thus achieving high precision leveling.       Compared with other leveling methods, the control system of the machine has the functions of sotring ,calling ,editing process and equipment p...
