Sheet metal processing
The progress and development of automation technology has greatly promoted the development of the facade Sheet metal processing industry, which is mainly reflected in the following aspects.
2.1 Cutting
The current relatively advanced processing method is used, that is, the CNC flattening machine is used for unloading. Except for the assistance of a forklift for loading, the rest of the work can be completed by only one employee operating the flattening machine. The processing efficiency and dimensional accuracy are relatively high. It is a processing method generally adopted by large and medium-sized anti-theft door manufacturers.
2.2 Pressing
The unloaded boards are transported to this process by a forklift. In order to avoid sprains and bruises on the boards, two employees should be responsible for loading materials and two for unloading. The press table should be kept clean to prevent pits on the facade.
2.3 Shearing
Due to the difference in the pressing shape of the facade and the difference in the performance of the material, the size of the same size plate may change greatly after different pressing, so the plate should be cut after pressing, and the three sides of the shearing plate should be cut, which is beneficial Ensure dimensional accuracy and prevent diagonal errors (especially important for the production of non-standard doors).
2.4 Cutting, punching, bending
In the cutting, punching, bending and other processes of the facade, automation technology can be selectively used to better connect the three processes, which can not only greatly reduce the number of operators, but also improve the processing accuracy of the product , Effectively prevent product damage caused by human factors. Taking Figure 2 as an example, according to the current processing technology, 6 punching machines, 4 bending machines, and about 10 operators are required in the processing process, and the sheet metal parts need to go through more than 10 working steps. Cause problems such as sprains, pits and dimensional errors on the facade. After adopting automation technology, the door mirrors are firstly processed manually, and then placed on the conveyor line. The punches on both sides of the conveyor line are responsible for processing 1 to 7. After the punches are completed, they are automatically transported to the roller press line to complete the bending in the figure. 8, 9, 10 and 11, the final bending 12, 13 and 14 are done manually on two punching machines, the whole process only needs 4 to 5 operators, the main equipment required are: three punching machines, rolling line One line, two sets of rows and flushes, etc. Since the key processes in the whole process are basically automatically processed by the equipment, many man-made damages can be avoided, the processing efficiency is high, the labor intensity is greatly reduced, and the processing accuracy and dimensional stability of sheet metal parts are relatively good.
It is worth noting that: since there are many non-standard doors in the current anti-theft safety door market, in order to meet individual needs, manufacturers should design the width to be adjustable when introducing the combination of rolling lines and flushing. Usually, the processing range is 600~ 1000mm, it can be realized by ball screw. At present, there is a relatively mature technology in this area in China, which can basically meet the needs of manufacturers.
