在各类钣金零件的加工上有自身特的优势,尤其对于形状复杂或者薄板部件的加工可自动完成零件的加工。可以根据图纸要求,对不同尺寸要求和形状要求的孔进行自动加工,也可以对较大的,形状的孔和轮廓利用小冲模以小步距步冲的方式进行生产加工。加上结构简单的模具对于存在特殊加工工艺的钣金件,如:浅拉伸、翻边孔等也能够进行加工。与传统的冲压相比较来说,模具更加简单,加工范围广泛,加工能力显着提高,对于批量生产或者形式多样的产品加工来说尤为适合,这对于加工企业跟上市场发展步伐,满足产品需求是十分有利的,而且因为各方面费用的减少,使得企业的经济效益得到有效的提高。

侧壁有皱纹：产生零件侧壁有皱纹的主要原因是材料的厚度不够(比较小的允许厚度还薄)或上、下模安装时出现偏心，造成一边间隙大，另一边间隙小，防止措施为即时更换材料和重新调整模具。

杭州钣金加工厂家,通常情况下，钣金件具备较为明显的强度、重量以及成本等优势，同时相对于传统的零部件具备更加优良的到点性能，所以，截至目前，钣金件已经逐渐地被应用在了我国电子、通信等高科技优先域，

其次，因材料加工属性导致的造型约束，在工业钣金设备外观设计的过程中，设计师一般会运用到如下方法。，蒙德里安切割手法，这一手法在设计中的运用是非常广泛的。这要求设计师在平面构成上需要一定的功力。第二，叠层法，在叠层方法的时候我们是要根据蒙德里安方法结合运用的。通过叠层的处理让产品看起来透气且有立体感。第三，斜面切割拼接手法，该方法通过直面的斜切来取势，往往这种做让产品出现夸张特征。

焊接有氩弧焊，点焊等，点焊要考虑工件焊接的位置，在批量生产时考虑做工装保证点焊位置准确。为了焊接牢固，在要焊接的工件上打凸点，可以使凸点在通电焊接前与平板均匀接触，以保证各点加热的一致，同时也可以确定焊接位置，同样的，要进行焊接，要调好预压时间，保压时间，维持时间，休止时间，保证工件可以点焊牢固。点焊后在工件表面会出现焊疤，要用平磨机进行处理，氩弧焊主要用于两工件较大，又要连接在一起时，或者一个工件的边角处理，达到工件表面的平整，光滑。氩弧焊时产生的热量易使工件变形，焊接后要用打磨机和平磨机进行处理，特别是边角方面较多。

根据冲压的不同，有冷冲压(解释：对板料或热料施加压力)和热冲压两种方法，应根据Material的强度、塑性、厚度、变形程度和设备能力选择不同的冲压方法，同时还应考虑Material的原始热处理状态和使用。

杭州钣金加工厂家 火焰切割作为初的传统的切割方式由于其低，过去对加工质量请求不高，请求太高时再加一道机加工的工序能够处理，市场保有量十分大。如今它主要用来切割超越40mm的厚钢板。它的缺陷是切割时热变形太大，割缝太宽，糜费资料，再者加工速度太慢，只合适粗加工。

Hangzhou sheet metal processing factory

In all kinds of sheet metal parts processing has its own unique advantages, especially for complex shape or sheet metal parts processing can automatically complete the parts processing. According to the requirements of the drawing, the hole of different size and shape requirements can be processed automatically, or the hole and profile of larger shape can be produced and processed by small punching die with small step. In addition to the simple structure of the die for the existence of special processing technology of sheet metal parts, such as: shallow drawing, flanging hole can also be processed. Compared with the traditional stamping, die is more simple, the processing range, significantly improve the processing ability, for mass production and is particularly suitable for various forms of product processing, for the processing enterprises to keep up with the pace of market development, meet the demand of the product is very good, but because of the reduction in cost of various aspects, to effectively improve the economic benefits of enterprises.

Side wall wrinkles: the main reason for the wrinkles on the side wall of the parts is that the thickness of the material is not enough (relatively small allowable thickness is also thin) or eccentric when the upper and lower die is installed, resulting in large clearance on one side and small clearance on the other side, preventing measures to immediately replace the material and re-adjust the mold.

Hangzhou sheet metal processing factory, under normal circumstances, sheet metal parts have obvious strength, weight and cost advantages, at the same time, compared with the traditional parts have better point-to-point performance, so, up to now, sheet metal parts have been gradually used in China's electronics, communications and other high-tech fields.

Secondly, due to the modeling constraints caused by material processing properties, designers generally apply the following methods in the appearance design of industrial sheet metal equipment. Mondrian cutting technique, which is widely used in design. This asks stylist to need certain ability on plane composition. Second, the lamination method, in the lamination method we're going to use a combination of mondrian's method. Through the treatment of lamination, the product looks breathable and three-dimensional. Third, the bevel cutting and splicing method, which takes the potential through the bevel cutting of the face, often makes the product appear exaggerated characteristics.

Welding has argon arc welding, spot welding, etc., spot welding should first consider the position of the workpiece welding, in the mass production consider doing tooling to ensure that the spot welding position is accurate. For welding firmly on to the welding workpiece convex point, can make the convex point contact with the plate uniform before electric welding, to ensure the consistent of each point to heat, welding position can be determined at the same time, also, for welding, to adjusted the preloading time, the holding time, maintaining time and rest time, ensure the workpiece can spot welding is firm. After spot welding, welding scars will appear on the surface of the workpiece, which shall be processed by a flat grinding machine. Argon arc welding is mainly used for the processing of edges and corners of a workpiece to achieve the flatness and smoothness of the surface of the workpiece when the two workpiece are larger and connected together. The heat generated by argon arc welding is easy to deform the workpiece. After welding, it should be processed by sander and mill, especially the edges and corners.

According to the different stamping, there are two methods: cold stamping (explanation: pressure on the plate or hot Material) and hot stamping. Different stamping methods should be selected according to the strength, plasticity, thickness, degree of deformation and equipment capacity of Material, and the original heat treatment state and use of Material should also be considered.

Hangzhou sheet metal processing factory flame cutting as the beginning of the traditional cutting method because of its low, in the past, the processing quality requirements are not high, the request is too high and then add a machining process can be handled, the market possession is very large. Today it is mainly used to cut steel plates over 40mm thick. Its defects are too large thermal deformation cutting, too wide slit, waste of information, and processing speed is too slow, only suitable for rough processing.
