自动化技术在门面钣金加工中的应用探讨

2018-05-07 22:11:01 常州亿创钣金加工厂 阅读

自动化技术的进步与发展大大促进了门面钣金加工行业的发展,主要体现在以下几个方面。

2.1 下料

钣金加工厂家沿用当前较为先进的加工方法,即采用数控开平机进行下料,除装料需铲车等协助外,其余工作只需一名员工操控开平机即可完成,加工效率、尺寸精度都比较高,是大中型防盗门生产企业普遍采用的加工方法。

2.2 压形

由铲车将下料后的板材运输到该工序,为避免板材扭伤和碰伤,应该由两名员工负责上料,两名负责卸料,压机台面要保持清洁,防止门面出现凹点。

2.3 剪板

由于门面压形的不同和材料的性能差异等,同样尺寸的板材经过不同的压形后,其尺寸可能出现较大变化,所以应在压形后剪板,剪板应剪三边,有利于保证尺寸精度,防止对角线误差(对生产非标门尤为重要)。

2.4斩缺、冲孔、折弯

在门面的斩缺、冲孔、折弯等工序中,完全可以有选择性地采用自动化技术,更好地将三道工序衔接起来,这样不仅可以大大减少操作人员,而且可以提高产品的加工精度,有效地防止因人为因素造成的产品损伤。以图2为例,按照当前的加工工艺,加工过程中需要冲床6台,折弯机4台,操作人员约10人,钣金件需要经过10多道工步的流转,稍有疏忽,就造成门面的扭伤、凹点和尺寸误差等问题。采用自动化技术后,首先人工加工门镜,然后放到输送线,由输送线两侧的排冲负责加工完1~7,排冲完成后,自动输送到辊压线,完成图中的折弯8、9、10和11,最后的折弯12、13和14由人工在两台冲床上完成,整个过程只需要4~5名操作人员,需要的主要设备有:冲床三台、辊压线一条、排冲组合两组等。由于整个过程中的关键工序基本由设备自动加工完成,因而可以避免许多人为的损伤,加工效率较高,劳动强度大大降低,钣金件的加工精度和尺寸稳定性都比较好。

值得注意的是:钣金加工哪家好由于当前防盗安全门市场上的非标规格门较多,为满足个性化需求,厂家在引进辊压线和排冲组合时,应设计成宽度可调节,通常加工范围在600~1000mm,可采用滚珠丝杆实现,目前国内在此方面已经有了较为成熟的技术,基本可满足厂家的需求。 

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.

2.1 blanking

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.
