How To Improve Bending Efficiency Of Sheet Metal Cabinet Processing?

As we all know, the bending process is a key process in the sheet metal cabinet processing and forming process, and plays an important role in the entire sheet metal cabinet processing process.

The sheet metal bending process is still regarded as the "bottleneck process" in the sheet metal cabinet processing process in many factories. Because it seriously affects the rhythm balance between the upper and lower processes of the sheet metal pre-processing unit.


In the process of sheet metal cabinet processing, it is particularly important to improve the efficiency of the bending process. So do you know what is the production process of sheet metal cabinets? How to improve the bending efficiency of sheet metal cabinet processing?


1. Sheet metal cabinet production process

Sheet Metal Cabinet

Every product starts from scratch and goes through several processes before the finished product is finally displayed in front of everyone. So do you know the manufacturing process of the sheet metal cabinet that is the most common in our offices? Today, I will share with you the production process of sheet metal cabinets!


1) Cutting

We need to use a plate shearing machine to cut cold rolled steel plates into different sizes. According to different metal cabinet products and different cabinet panel positions (such as door panels, side panels, top panels, bottom panels, partitions, etc.), the size of the cut metal panels will also be different.


2) Dehorning

We use a punch press machine to remove the corners from the cut sheet metal. Different metal cabinet locations (such as door panels, side panels, tops, bottom panels, partitions, etc.) have different beveling styles. There are special molds for dehorning, and large factories generally use assembly line dehorning.


3) Bending

Use a plate bending machine to bend the metal plate with the corners removed. Depending on the location of the metal cabinet, the bending angle is also different.

4) Spot welding

After folding the side panels, top, middle panel, bottom panel, back panel, slides, partition beams, etc. of the metal cabinet, we need to use a spot welder to spot weld them. Different products are produced according to different metal cabinet styles. At this time, the entire metal cabinet is ready.


If you use a traceless spot welding machine for spot welding, the surface of the spot welded product will be smooth. No need to sand or putty.


5) Phosphating

Pickling and phosphating the spot-welded integral metal cabinet to remove grease and rust from the surface of the metal plate to prepare for the next steps.


6) Powder spraying

Put the cleaned metal cabinets into the spraying workshop for spraying. Nowadays, electrostatic powder spraying is generally used. The products produced have no pungent smell and are green and environmentally friendly.


The color of metal cabinets is generally gray and white. Each manufacturer uses different powders and different powder batches. Generally there will be some color difference. The sprayed product needs to be heated at a high temperature of 180-200 degrees Celsius.


7) Assembly

Then, we can transport the sprayed products to the assembly workshop for assembly. In the assembly workshop, we need to debug partitions, slides, upper drawers, door panels, etc.


After the assembly is completed and the quality inspector inspects it, it can be packaged. After packaging, the steel cabinet products can be sorted into the finished product warehouse.


2. Methods to improve the bending efficiency of sheet metal cabinets

Bending Efficiency Of Sheet Metal Cabinet Processing

1) Optimize the bending process

The bending process is a key factor in achieving high-efficiency processing. Optimizing the bending process of sheet metal cabinet processing includes adjusting the bending angle, selecting the appropriate bending sequence, optimizing the bending parameters, etc.


By adjusting the bending angle and selecting the appropriate bending sequence, we can mprove the bending efficiency and processing accuracy. Optimizing the bending parameters can improve the strength and stiffness of the bending and ensure the smooth progress of the bending process.


2) Use automated processing

Automated processing is an important way to achieve sheet metal cabinet processing and bending efficiency. An efficient and high-precision bending process can be achieved through automated processing.


Automated processing can use robots or automated production lines to achieve automation and intelligence in processing, improve production efficiency and reduce production costs.


3) Reasonably plan the processing process

Reasonable planning of the processing process is also an important means for the efficiency of sheet metal cabinet processing and bending. During the processing of sheet metal cabinets, reasonable arrangements and planning need to be made according to the processing needs of different needs. Ensure the smooth progress of all aspects, thereby improving the efficiency and accuracy of the entire sheet metal cabinet processing process.

4) Choose suitable bending equipment

Bending equipment is the core of bending processing in the processing of sheet metal cabinets. Choosing the right bending equipment is crucial to achieving efficient processing.


Different bending equipment is suitable for different processing needs. For example, manual bending machines are suitable for small-scale processing and bending with high flexibility. The automated bending machine is suitable for large-scale processing and high-precision bending.

The bending center can bend complex shapes in various combinations such as right angles, non-right angles, arcs, upper and lower bends, etc., and is used in the metal forming field of different workpieces in different industries.


The equipment is equipped with a pure electric servo system, replacing hydraulic drive. SC bending center has the advantages of environmental protection, fast speed, high precision and maintenance-free.


Domestic steel cabinet shell field, such as cabinets, tool cabinets, electrical cabinets, etc. The plate materials are mostly cold-rolled plates and stainless steel. In the bending process, how to complete the requirements of mass production with high quality and efficiency?


Take metal cabinets as an example:

Common cabinets on the market are mainly composed of door panels, bottom panels and other parts. The bending process of workpieces with different structures is also different. Using traditional bending equipment requires re-opening molds according to different types of bent workpieces, which undoubtedly increases mold costs and production time costs.
