Automotive stamping parts are more and more widely used in industry. We are specialized in producing various stamping parts. The stamping parts produced by our company are exported all year round at home and abroad, and we have the right to import and export independently. Let's talk about the stamping process.

Installation process to classify, stamping is generally divided into forming and separation of two major processes. Each process has its own inspection standards. The goal of forming is to make the sheet metal into the required shape and size without breaking the blank. The purpose of separation process is to separate the stamping parts from the sheet metal according to the established target, and at the same time, the quality of the separation section must meet the standard requirements.

The precision of the first mock exam is very good, basically the same size and uniform size, smooth surface and good inner quality. Moreover, it can meet the general assembly requirements without further machining, which saves a lot of cost and time. It is highly praised by the industry. Therefore, the application of stamping parts in industrial production is more and more extensive.

How to control the quality of stamping parts must be treated with caution, because stamping parts are basically used in automobile parts industry, and the requirements are very strict. The following by Nanpi County Kangle mechanical and electrical products manufacturing Co., Ltd. for you to reduce a simple, how to control the quality of stamping parts in the production process.

There are many kinds of automobile stamping products. The shape is complex and precise. The production process must be strictly controlled, from raw materials to every detail of processing. In particular, the manufacturing process of the middle shield bracket of the car, which is the key load-bearing connector of the car, is equivalent to the frame of a house. Once the frame structure of the house is not reliable, no matter how well you decorate the house, once there is a typhoon or tornado, it will fail. We require that the intermediate bracket must have the function of bearing impact, and must have enough bending strength and very good toughness. Therefore, in the process of manufacturing, we must consider many aspects, and the quality control department should strictly control the quality.

The problem of concave convex often appears in the production of stamping parts. There are many reasons for this phenomenon, such as raw materials, molds, impurities and so on, which affect the quality of stamping parts. In order to avoid the recurrence of similar problems, attention should be paid in the production process of stamping parts, so the causes of concave convex are explained in detail.

On the one hand, it is due to the personnel operation, and the operation is not standardized in the stamping process, including the collision of the product moving into the mold, the unreasonable adjustment of the conveyor belt height, the deformation of the loading and storage of the working position equipment, etc. The existence of these factors will make the surface of stamping parts concave and convex.

There are also process reasons, unreasonable design of the working speed of the stamping machine; iron powder produced in the drawing process; burr left on the cut-off surface are also important factors causing the concave convex of stamping parts. We should take different preventive measures for different reasons to achieve certain results.

In the general production process, which reasons will lead to the coil phenomenon of stamping parts? The following is a brief introduction from Nanpi Kangle electromechanical products manufacturing Co., Ltd

1、 There are irregular damage at the edge of the material and the material beyond the qualified quality standard.

2、 Due to the stick sliding, when there is a foreign matter falling into the back of the coil forming a bubble.

3、 There are foreign matters outside the material on the surface or inside of the steel. When the foreign matters are peeled off, the coil material is like a scar, which is very hard to see.

4、 When there is a foreign object sticking to the stick, the stick trace is obvious because of the depth of the surface caused by the foreign body.

5、 The scratch caused by the surface of the stick or foreign body will wrinkle or deform due to the uneven stress, which will lead to the breakage of the coil corner.
