STRIPPIT PX 1530 配备 FA-P 和 CADMAN SUITE

复杂的大型项目

Groven+是非民用建筑外立面的专家:窗户、穹顶和外墙。由于这些项目的规格,特别是复杂度较高,需要考虑多方面因素。项目的平均外墙面积约为 4000 平方米,最多可达 35000 平方米。Groven+引以为傲的一个创新项目是安特卫普港口大厦,由著名建筑师Zaha Hadid 设计。“这些项目具有较高的建筑自由度,通常采用非标尺寸、形状和颜色。未来,我们将专注开发此类项目。”钣金生产经理 Jeroen Van De Putte 说。 对于此类项目,需要一个工程和项目管理精英团队。基于建筑师的规划 – 通常不是 3D 形式 – 工程师创建概念,计算稳定性、热学和声学数据,并进行可行性研究。项目管理人员从这一阶段开始监控项目。Groven+ 在内部制作剖面图和外立面要素,并且负责安装和现场监控。

自动化冲裁系统

过去,组件的生产涉及大量人工操作。使用剪板机将钣金材料切割为所需尺寸,然后逐张进行冲裁和折弯。这个流程非常耗时,对操作员来说,劳动强度很高。

Van De Putte 说:“去年,我们安装了 LVD Strippit PX    1530 冲床以及扩容刀具库 ( ETM ) 和柔性自动化 ( FA-P ) 之后,手动操作减少了 三分之一。冲床还连接到容纳了五座料塔的仓库,其中每座料塔包20个托盘位置。整个系统都在 CADMAN® 软件上运行。”

高效流程

自动化水平逐渐提高,准备工作也随之增多。首先,要将 CAD 文件导入到 CADMAN-SDI 中。随后,这些文件可供 CADMAN-B 和 CADMAN-P 访问 (LVD 的离线折弯和冲裁软件),以确保在冲裁期间,可以优化顺序、排样和刀具选择。接着,这些文件将发送到设备。当操作员开始作业时,信号会发送到仓库,拾取某个托盘的钣金材料。FA-P 装载钣金材料,并在作业完成后,直接将冲裁后的零件放入正确的托盘。随后,它们装在托盘中被输送到两台折弯机上,或被送回仓库。

Strippit PX 单头冲床配备 20 个可分度旋转工位。尽管 Groven+ 已经拥有了丰富的刀具选择方案,他们仍决定引入 ETM,获得 40个额外工位。

小批量生产



Groven+ 不从事大批量生产。每个新项目所需的零件各不相同。Groven+ 选择影响深远的自动化技术不是很奇怪吗?Van de Putte 不这么认为:“出于项目规模的原因,排样非常大。一个排样可用于 100 张钣金材料。通常需要加工一次性部件和需求量极大的零件。这使我们的系统具有经济可行性。”

Martens 补充道:“自动化不再是大批量生产的专属技术。这个软件的设计宗旨就是使自动化适用于小批量生产。此外,也不应该忽视人工处理成本。这部分支出相当可观。”

生产率提高两倍

该系统投入使用已有一年时间,是第一次评估的最佳时机。

Van De Putte 说: 

“调试这种系统意味着陡峭的学习曲线。一开始,我们每月加工 200 到 300 张钣金材料,但如今已经接近 1000 张。这个数目当然还有增长空间,因为目前我们不在夜间开工,但是从长远来说需要夜间运行设备。”

LVD 冲床产品经理 Pierre Comhaire 补充道:

这个系统具备冲裁、成型、 攻丝等能力,可以创造巨大价值。他们会逐步发挥系统的所有潜能,未来可能会升级仓库或分拣单元,或者通过 CADMAN-JOB 分析 KPI 以进一步优化流程。LVD系统采用模块化形式,可以按照客户的发展进度来扩展。

The company Groven+ was founded in the 1990s and has specialised in building facades. That is to say, aluminium joinery, aluminium and glass facades, mainly for larger office buildings, so no residential buildings. 

Although aluminium profiles form the basis of aluminium joinery, Groven+ has always invested in sheet metal working. Our first machines in the early 1990s were also from LVD. We've always considered it important to include wall cladding in facade construction. We've also seen that our new machines open a lot of doors for us, turn new projects with more complex cladding. 

The group's annual turnover is €30 million, in Belgium, Luxembourg and France. To continue our success, we need top notch machinery. That's why we wanted an automated punch press with a warehouse.

At Groven+, we opted for a fully automated LVD machine. This replaced a standalone machine, without a warehouse, that had sheets delivered to it on a pallet. Everything was mixed up. Organising the sheets was very labour-intensive.

Now we have a fully automated magazine with 5 towers and 100 pallet positions, with 50 pallets of 4 by 2 metres. The press punches sheets of 4 by 1.5 metres. We don't just use the warehouse for storing sheets, it's also where we keep punched parts. 

Punched parts are stored in the warehouse on a 4 by 2 metre pallet. So if we need to process them further, we can retrieve them using the loading table. During stocking or retrieving material, production is not interrupted.

Now we work with sheets from the warehouse. Several parts are nested per sheet and then processed in one go by the punch press. 

All the parts are automatically unloaded, one at a time, onto the unloading table of the punch press. In the past, three people were needed to cut and punch sheets. Now, there is one person operating the punch press. The installation went very smoothly. We set up this entire system in one month and the start-up took six to eight weeks. 

We received all the information we needed to start production efficiently.

In the future, we will continue to invest in the latest technology, also integrated to the machines we have and from which we expect a lot. And there's still the programming, which is also quite a learning curve for us and which we are making great strides in. We use LVD's CADMAN software. Now our engineering office sends us 3D files instead of the 2D drawings that we used to have to redraw. 

The software imports the 3D files and gives us an unfold with the correct bend allowance. We can use those files to punch the parts very quickly and accurately.

When it comes to efficiency, it’s quite simple. When you switch from standalone to automated, the difference is like night and day. The press brake used to have to wait for the punch press, but now the press brake can hardly keep up.
