机箱机柜加工剪切要求要达成什么标准?

发布时间:2023-11-13来源://www.aqfitlab.com/浏览量:

钣金加工剪切办法是一对翻滚方向相反的圆盘剪刃对板料进行剪切,机箱机柜剪切是指将原材料按照需要将其剪切成所需形状的材料,同时也可以经过剪板机得到矩形工件的工艺过程。剪切材料厚度为机床额定值的各种钢板、铜板、铝板及非金属材料板材,而且必须是无硬痕、焊渣、夹渣、焊缝的材料,不允许超厚度,严禁超负荷使用剪板机。不得剪切淬火钢料和硬质钢、高速钢、合金钢、铸件及非金属材料。
The cutting method for sheet metal processing involves a pair of disc cutting edges with opposite rolling directions to cut the sheet metal. The cutting of the chassis and cabinet refers to the process of cutting raw materials into the desired shape according to needs, and also the process of obtaining rectangular workpieces through a plate shearing machine. Various steel plates, copper plates, aluminum plates, and non-metallic materials with a thickness equal to the rated value of the machine tool must be cut, and must be free of hard marks, welding slag, slag inclusions, and weld seams. Excessive thickness is not allowed, and overloaded use of the cutting machine is strictly prohibited. Do not shear quenched steel materials, hard steel, high-speed steel, alloy steel, castings, and non-metallic materials.
下面是钣金件、剪切要求仅供参考:
The following are sheet metal parts and cutting requirements for reference only:
一、机箱机柜钣金件、剪切要求
1、 Requirements for sheet metal parts and cutting of chassis and cabinet
剪切断面:钣金件因剪切粗糙,对于氧化、电镀或喷塑件,剪切端面要工艺应增加打磨抛光工序;
Cutting section: Due to rough cutting of sheet metal parts, for oxidation, electroplating, or spray molded parts, the cutting end face should be processed by adding polishing processes;
剪切平行度:剪切平行度约为0.3%,当零件精度高于该值时,工艺应采取其它方式下料;
Shear parallelism: The shear parallelism is about 0.3%. When the accuracy of the part exceeds this value, the process should adopt other methods of cutting;
剪切毛刺:剪板机剪切毛刺约为板厚4~6%,当毛刺大于0.1时,需要增加去毛刺工序。
Cutting burrs: The shearing machine cuts burrs about 4-6% of the plate thickness. When the burrs are greater than 0.1, an additional deburring process is required.
二、剪切间隙选择
2、 Cutting gap selection
剪切间隙:按材质、板厚选择剪切间隙能保证零件剪切质量和设备剪切安全,所以正确选择剪切间隙尤为重要。
Shearing gap: Choosing the cutting gap based on material and plate thickness can ensure the quality of part cutting and the safety of equipment cutting, so it is particularly important to choose the correct cutting gap.

三、剪切角度选择
3、 Cutting angle selection
剪切角度选择:按材质、板厚选择剪切角能提高零件的剪切质量;对于相同材质及板厚的零件,若剪切角取小值,零件剪切的扭曲变形的相对减小、剪切质量提高;相反,零件的扭曲变形相对增大,剪切质量则降低。
Cutting angle selection: Selecting a cutting angle based on material and plate thickness can improve the cutting quality of the part; For parts of the same material and plate thickness, if the shear angle is taken as a small value, the relative reduction of deformation caused by the part's shear and the improvement of shear quality will be achieved; On the contrary, the twisting deformation of the parts increases relatively, while the shear quality decreases.
四、剪切间隙及调整
4、 Shear clearance and adjustment
影响零件剪切质量的主要因素是剪切间隙,所以操作工必须依据剪切的材质及厚度,通过旋转机床上的刻度盘,将上、下切刀间隙调整到板材剪切的规定范围。
The main factor affecting the cutting quality of parts is the cutting gap, so operators must adjust the gap between the upper and lower cutting knives to the specified range for sheet cutting by rotating the dial on the machine tool based on the material and thickness of the cutting.
五、上下切刀及后档
5、 Upper and lower cutting knives and rear gear
钣金件剪切通过机床系统中程序控制各机构相互动作,由上、下刀片完成剪切;剪切平行度则是由后挡及下切刀之间的平行精度保证。
The cutting of sheet metal parts is controlled by the program in the machine tool system to control the mutual action of various mechanisms, and the cutting is completed by the upper and lower blades; The parallelism of shearing is ensured by the parallelism accuracy between the rear gear and the lower cutting tool.
