关于机柜钣金加工技术的先容

在钣金加工行业领域,大家一直在追求对以往技术加工模式的突破,机柜钣金加工制造技术的出现,大大提高了钣金件产品的多品种、多工序、中小批量的生产效率,实现了薄板平面的钻孔、攻丝、形状切割、图案刻铣、底面倒刮毛刺等工序的综合、低成本、自动化加工。钣金加工厂引进激光产品以后,有针对性的适合钣金加工行业,多功能激光加工期器,可以同时实现打孔、不规则复杂图案的切割、各种复杂图形文字的雕刻、同型和异型的材料焊接等等。

钣金零件设计的结构工艺性

(3)设计折弯零件的截面形状时,应考虑到模具结构特点及脱模的需要

(4形状对称零件的圆角半径应对应相等,以保持零件的平衡,即:r,=r 2,R 3=Rt,外径尺1可不作规定

(1)钣金结构的焊缝应认真进行处理,既要保证焊接强度,又应注意不致影响到外观,粗糙的焊缝给人以产品质疑低劣之感。

(2)现代造型要求轮廓清晰,挺括、转折鲜明,钣金加工厂在加工要求中对钣金结构来说比较小的弯角半径易于保证板面的平整。

(6)折弯有孔零件时,若孔位于弯曲线的附近,在弯曲时孔的形状将发生变形。为避免孔的变形,必须使这些孔分布在变形区外。从孔边线到弯曲半衢中心距离为:

当t<2mm时,L≥t

当t≥2mm时,L≥2t

(5)钣金加工厂在实际加工过程中如果要求零件内侧半径r很小或清角时,应事先在零件弯曲处开槽,或折弯后再铣槽。对于零件弯曲臂高度晰艮低时,用此法便于折弯成形。

(8)如果弯曲零件的弯边,弯曲至材料内边时,应事先在落料零件上增加工艺孔、槽或缺口,以防止零件发生裂纹和变宽现象。

(7)当零件弯成90。时,为保证弯边有足够的变形稳度,必须使弯边的直线高度不小于2t若小于2t,则必须压槽或增大弯边高度,弯曲成型后再加工铣掉,否则不能保证角度要求。支臂零件,其侧面弯边斜线已进入变形区,当弯边直线高度小于2t时,必须加高弯边尺寸。

机柜的加工方式适合于对钣金的加工。薄板金属切割机激光切割机三大模式类型主攻薄板板材,加工速度快,工艺精美,经济效益好。多功能和针对性的薄板金属切割机的开发运用丰富了钣金加工市场,也必将取得更好的发展前景。关于机柜钣金加工技术的功能以及性能特点,钣金加工厂整理了如下资料:

An introduction to the processing technology of cabinet sheet metal

In the field of sheet metal processing industry, we have been pursuing the breakthrough of the former technology processing mode, the appearance of the machine sheet metal processing and manufacturing technology, which greatly improved the production efficiency of the multi variety, multi process and small batch production of sheet metal parts, and realized the drilling, tapping, shape cutting, pattern milling and bottom surface of the sheet metal plane. Comprehensive, low cost, automatic processing of reverse scraping and other processes. After the introduction of laser products, the sheet metal processing plant is suitable for the sheet metal processing industry and the multi-function laser processing period device. It can simultaneously achieve perforation, irregular complex pattern cutting, various complex graphic characters carving, same type and heteromorphic material welding and so on.

Structural technology of the design of sheet metal parts

(3) when designing the sectional shape of bending parts, the structural characteristics of the die and the need for demoulding shall be taken into account.

(4 the fillet radius of the symmetrical parts should be equal to maintain the balance of parts, that is, R, =r 2, R 3=Rt, and outer diameter 1.

(1) the weld of the sheet metal structure should be dealt with seriously, not only to ensure the welding strength, but also to pay attention to the appearance of the weld. The rough welds will give the product a poor sense of the product.

(2) modern modeling requires clear outline, crisp and sharp turning. The small bending radius of the sheet metal processing plant for sheet metal structure is easy to ensure the flat surface of the plate.

(6) when bending a hole part, if the hole is located near the curve, the shape of the hole will be deformed when bending. To avoid hole deformation, these holes must be distributed outside the deformation zone. The center distance from the hole line to the curved half thoroughfare is as follows:

When t<2mm, L is more than t

When t is more than 2mm, L is more than 2T

(5) in the process of processing, if the inner radius of the part R is very small or clear in the process of processing, the groove should be slotted at the bend of the part or after the bending. This method is convenient for bending forming when the bending arm height of parts is low.

(8) if the curved edge of a curved part is bent to the inner side of the material, the process holes, grooves or gaps should be added to the blanking parts in advance so as to prevent the cracks and widening of the parts.

(7) when the part is bent to 90. In order to ensure that the edge has sufficient deformation stability, the line height of the curved edge must be less than 2T less than 2T, then the groove or the edge height must be increased, and the bending and milling will be made after the bending. Otherwise, the angle requirement can not be guaranteed. The side diagonal slash of the supporting arm part has entered the deformation area. When the straight line height of the bent edge is less than 2T, the bending edge dimension must be increased.

The processing method of the cabinet is suitable for the processing of sheet metal. Sheet metal cutting machine laser cutting machine three main types of main attack sheet plate, processing speed, exquisite process, good economic returns. The development and application of multifunctional and targeted sheet metal cutting machines will enrich the sheet metal processing market, and will also achieve better prospects for development. With regard to the function and performance characteristics of the cabinet sheet metal processing technology, the sheet metal processing plant collated the following information:

1. The machine sheet metal processing equipment can realize the comprehensive automatic processing of the sheet metal plane, automatically exchange the cutters such as the drill, taps and milling cutters, and can automatically realize the drilling, tapping, irregular and complex shape milling, plate pattern carving and milling, and the back scraping of the hole bottom.

2, do not need all kinds of molds, the use and processing costs are minimal, all processes are processed through ordinary cutting tools.

3. No clamping fixture is needed for all kinds of flat metal parts. The installation of sheet metal parts is very convenient, stable and reliable.

4, the use of special compaction device, positioning processing and mobile cutting process are stable and reliable;

5, automatic coordinate movement, automatic tool switching and automatic processing, high degree of automation.
