激光切割加工VS常规钣金加工方法的区别

2018-05-13 16:39:09 常州亿创钣金加工厂 阅读

激光切割加工与其他热切割方法相比,具有工作区域小,切口小的有点,其他热切割,不是像激光束那样作用于一个非常小的区域,导致切口宽、热影响区比较大和明显的工件变形。济宁激光切割技术能够切割非金属,而其它热切割方法则不可以。

Compared with other hot cutting methods, laser cutting has small working area, small incision and other hot cutting, which does not act as a laser beam on a very small area, resulting in wide incision, larger heat impact zone and obvious deformation of the workpiece. Jining laser cutting technology can cut non-metal, while other hot cutting methods can not.

以下是不同切割设备的比较:The following are the comparison of different cutting equipment:

1、等离子切割

切割速度明显快于氧乙炔切割,但切割质量较差,切边顶部呈圆头状,切边明显起波浪形,还要防止电弧产生的紫外线辐射。它稍优于激光切割机之处在于适合切割较厚钢板和对光束反射率高的铝合金等。

1. Plasma cutting

The cutting speed is faster than that of oxyacetylene cutting, but the cutting quality is poor, the top of the cutting edge is round head, the cutting edge is obviously wavy, and the ultraviolet radiation produced by the arc is also prevented. It is slightly better than the laser cutting machine, which is suitable for cutting thick steel plates and aluminum alloy with high reflectivity.

2、氧-可燃体切割

这种方法主要用于切割低碳钢,由于它热输入影响大,切割速度低,很少被用来切割20MM以下要求尺寸精确的材料。

2, oxygen - combustible body cutting

This method is mainly used for cutting low carbon steel. Because of its high heat input effect and low cutting speed, it is rarely used to cut the material with precise size below 20MM.

3、模冲

大量生产零件用模冲方法成本低,生产周期短。但它对设计上的变化的适应性很差,新的模具需要长时间设计,造价高,对中、小规模的生产来说,激光切割的特点就会充分显示。另外,激光程控切割便于工件紧密编排,节省材料,而模冲则需要每个工件周围预留材料。

3, mold flushing

The die stamping method for mass production parts has low cost and short production cycle. But it has poor adaptability to the design changes. The new mold needs a long time design and high cost. For medium and small scale production, the characteristics of laser cutting will be fully displayed. In addition, laser controlled cutting facilitates the tight layout of the workpiece and saves material, while die stamping requires materials reserved around each workpiece.

4、复杂零件分段冲切

一般情况下,冲床经常要冲切比模具尺寸大得多的工件,有些工件还很复杂,这就导致切边呈许多小贝壳状刃口,需要第二次预备性加工整修。另外冲头会形成比激光切割机宽得多的切口,产生大量铁屑。

4. Subsection punching and cutting of complex parts

In general, the punching machine often needs to scour a much larger workpiece than the die size, and some of the pieces are very complex, which leads to a lot of small shell shaped edges, which requires second preparative refurbishment.  In addition, the punch will form a much wider incision than the laser cutting machine, resulting in a large amount of iron filings.

5、电加工

一般,有利用电腐蚀或熔解效应的电火花和电化学加工两种方法,用于坚硬材料的精细加工,切口粗糙度较好,但切割速度要比激光切割机速度慢几个数量级。

5. Electrical machining

Generally, there are two methods of electric spark and electrochemical machining using electric corrosion or melting effect. It is used for fine processing of hard materials, with better cut roughness, but the cutting speed is several orders of magnitude slower than that of laser cutting machine.

6、锯切

切割薄金属,其速度明显比激光切割慢,而且激光作为一个灵活的无接触、仿形切割工具,可从材料的任何一点开始切向任何方向切割。这一点,锯切是难以做到的。

6, sawing

Cutting thin metal, its speed is significantly slower than the laser cutting, and the laser as a flexible, contact cutting tool, can cut from any point of the material to cut in any direction. In this case, sawing is difficult to do.

7、水切割

可切割许多金属材料,但费用很高。

7. Water cutting

Many metal materials can be cut, but the cost is very high.

激光切割和其他切割方法的区别

激光切割与传统切割法的对比:

The difference between laser cutting and other cutting methods

Comparison between laser cutting and traditional cutting method:

1、激光束聚焦后功率密度高,能够切割任何难加工的高熔点材料、耐高温材料和硬脆材料等。
1. After laser beam focusing, the power density is high. It can cut any hard to melt high melting point material, high temperature resistant material and hard brittle material.

2、割缝窄,一般为0.1-1mm,割缝质量好,切口边缘平滑,无场边,无切割残渣。对轮廓复杂和小曲率半径等外形均能达到微米级精度的切割,并可以节省材料15%-30%。
2, narrow slit, generally 0.1-1mm, good quality of slotting, smooth edge of cutting edge, no field edge, no cutting residue. It can cut micron level precision with complex contour and small curvature radius, and can save material 15%-30%.

3、非接触切割,被切割工件不受机械作用力,变形极小。它适宜于切割玻瑞、陶瓷和半导体等硬脆材料及蜂窝结构和薄板等用性差的零件。
3, non-contact cutting, the workpiece is not subjected to mechanical force, deformation is minimal. It is suitable for cutting hard and brittle materials such as Bo Li, ceramics and semiconductors, and parts with poor usability such as honeycomb structure and thin plate.

4、切割速度高,一般可达2-4m/min。
4, the cutting speed is high, and it can reach 2-4m/min.

5、切割的深宽比大,对于金属可达30左右,对于非金属一般可达100以上。

5, the cutting depth to width ratio is about 30, which can reach more than 100 for non-metal.
