The progress and development of automation technology has greatly promoted the development of the facade sheet metal processing industry, mainly reflected in the following aspects.
Sheet metal processing manufacturers continue to use the more advanced processing methods, that is, the use of numerical control Kaiping machine for feeding, except for loading and other assistance, the rest of the work only need one employee to control the Kaiping machine, processing efficiency, size accuracy are relatively high, is a large and medium-sized anti-theft door production enterprises commonly used processing methods.
2.2 pressure shape
The plate will be transported to this process by a forklift. In order to avoid the sprain and bruise, two employees should be responsible for the material, two are responsible for discharging the material, the surface of the press should be kept clean, and the surface of the door can be avoided.
2.3 shear plate
Because of the different pressure shape of the door and the difference of material performance, the size of the plate of the same size can be changed greatly after different pressure shape, so it should be cut after the compression, and the shear plate should be cut three sides, which is helpful to ensure the dimensional accuracy and prevent diagonal error (especially important for the non standard production).
2.4 chopping, punching, bending
In the process of cutting and missing, punching and bending, the automatic technology can be used selectively to better connect the three processes. This can not only greatly reduce the operator, but also improve the processing precision of the product, and effectively prevent the product damage caused by human factors. Take Figure 2 as an example, according to the current processing technology, the processing process requires 6 punches, 4 bending machines, about 10 operators, and the sheet metal parts need to pass through more than 10 steps, a slight negligence, resulting in a sprain, a concave point and a size error. After the use of automation technology, the first manual processing of the door mirror, and then put into the transmission line, the discharge line on both sides of the line is responsible for processing 1~7, after the completion of the discharge, automatic delivery to the roller press line, complete the bending of 8, 9, 10 and 11, the final bend 12, 13 and 14 by manual in two press machine completed, the whole process only needs 4 To 5 operators, the main equipment needed is: punch press three, roll press line, row and punch combination two groups. Because the key process in the whole process is finished by the equipment automatically, it can avoid many man-made injuries, the processing efficiency is high, the labor intensity is greatly reduced, the processing precision and the dimensional stability of the sheet metal parts are better.
It is worth noting that: which is a good sheet metal processing because of the non standard doors on the current security door market, in order to meet the personalized demand, the manufacturer should design the width adjustable when introducing the roller pressure line and the row and blanking combination, usually the processing range is 600 to 1000mm, and the roll bead wire can be realized in this respect at present. There are already more mature technologies that basically meet the needs of manufacturers.
