Now more and more sheet metal parts are used in all aspects of our lives. So what is the general production process of sheet metal parts? How do we apply at work? Assetprecision Manufactor made a discussion on these contents.
Processing sheet metal parts are a comprehensive cold processing process for metal thin plates (usually below 8mm), including cutting, flushing/cut/composite, folding, welding, riveting, stitching, molding (such as car body and machine tool protection). The obvious feature is that the thickness of the same part is consistent.
There are many sheet metal parts in the manufacturing industry. Generally speaking, after receiving the official production drawings from the sheet metal parts, the sheet metal manufacturers usually follow the steps below.
1. Check the drawings
Why do sheet metal manufacturers usually review the drawings in the first step? This is because many engineers have many engineers who have not been able to contact the production process of sheet metal parts, and may not be proficient in the production process of sheet metal parts, so many times the drawings drawn will have details. The sheet metal manufacturers are professional and proficient in these, so sheet metal manufacturers will check the drawings before confirming the size and related requirements of the customer. It will be clear that the customer's final needs will enter the writing of production processes.
2. Determine the plate model and confirm the date
This is mainly to confirm the material according to the requirements of the customer's drawings, and to confirm the order of the plate according to the number of orders. Regardless of whether the corresponding board in the factory is in the inventory, the customer needs to be notified in a timely manner. Because this directly affects the delivery of the goods, especially for customers with urgent delivery periods, if they do not communicate in advance, they will be passive in the later period, and may even cause breach of contract due to their own reasons. This is a bad impact on the reputation and reputation of the factory. Therefore, it is the first step to confirm that the plate model and dating is the first step.
3. Production and processing process and production process
Common cold -rolled plates, rolled and peaceful plates. This is the most critical place for sheet metal parts. Generally speaking, the production process of sheet metal parts is as follows: ① Calculate the length of the expansion and confirm the size of the feed. ② Bend ③ Machinery processing ④ Surface treatment ⑤ Packaging delivery.
① The computing development length is an important content. When calculating the length of calculation, we must comprehensively consider the expansion coefficients of different materials. Generally speaking, each factory has experience in the development coefficient of common materials. We can apply it. If it is laser feeding, we generally do not leave the balance. If it is a shear machine, we need to reserve the amount of processing, and we need to determine the most suitable way of discharge, because this directly affects the material utilization rate, one is better The method of discharge must be as much as possible under the premise of meeting the processing process of the components.
② Bend, we are doing this step. According to the requirements of the drawing, we can choose the appropriate bending mold. If the general -purpose bending mold cannot meet our requirements, we may need to make a special bending mold.
③ The main purpose of mechanical processing, the main purpose of mechanical processing is to process the characteristics of the two processes of feeding and bending. Common ones such as attack teeth, riveting snails, etc. We can only complete these processes after bending. This is because if these processing is performed before bend, it may be deformed when bending.
④ Riveting metal parts: Surface treatment, this is the last set of processes before delivery, mainly on the surface processing of parts according to the customer's drawing requirements. Common surface treatment is brushed, spray paint, oxidation, and so on.
⑤ Painting metal parts: Packaging delivery, after completing the finished parts, we will perform the final measurement and inspection of all parts. This is mainly to check the quality of the appearance. There are no paint flaws, whether there are surface quality problems, etc. Size measurement is also the final verification and inspection. Generally speaking, the previous craftsmanship is sufficient to ensure the accuracy of the size of the finished product, and in the process, it is controlled by size. If the size problem is discovered before the last delivery, it is an unforgivable error for sheet metal manufacturers. This loss may be borne by sheet metal parts manufacturers.
After confirming that there are no problems, we can pack and ship. Such a complete sheet metal parts production process came out.
