Metal stamping parts refers to the forming of metal or non-metal sheets by stamping and stamping by the pressure of the press. As a fitting for many equipment, metal stamping parts are tested from production to delivery to ensure that they meet the requirements and that the equipment is used properly. How to detect the metal stamping parts? Let's take a look at it.

Introduction

 

Metal: steel or some non-ferrous metal parts, processing methods: cold/hot stamping, extrusion, rolling, welding, cutting and other processes, the definition is broad.

Stamping parts: The most common metalworking is steel/non-ferrous metal molds. Such as steel at room temperature, which are formed by stamping under specified pressure?

It includes some electronic equipment, automobile parts, decorative materials and so on. What we usually say is stamping part means cold stamping part. For example, an iron plate, if you want to turn it into a fast food plate, you have to design The working surface of the mould is the shape of the plate. Use the die to press the iron plate to become the plate you want. This is cold stamping, that is, stamping hardware directly with a die.

 

Testing method

 

The hardness of the metal stampings is measured using a Rockwell hardness tester. Small, complex-shaped stampings can be used to test small planes that cannot be tested on ordinary benchtop Rockwell hardness testers.

 

Stamping parts processing includes punching, bending, drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloys. Plate, aluminum and aluminum alloy plates, etc.

 

The main purpose of hardness testing of stamping materials is to determine whether the annealing degree of the purchased metal sheet is suitable for subsequent stamping parts processing. Different types of stamping parts require different hardness plates. Aluminum alloy sheets for stamping can be tested with vickers hardness Tester. Barcol durometer can be used when the material thickness is greater than 13mm. Pure aluminum plate or low hardness aluminum alloy plate should use a barr hardness tester.

 

What are its characteristics?

 

1. It is made by stamping on the premise that the data is not expensive. The parts are light in weight and good in rigidity. After the sheet is plastically deformed, the internal structure of the metal is improved, and the strength of the hardware is improved. .

2. Metal stamping parts have high dimensional accuracy, uniform with the same modular dimensions, and have good interchangeability. It does not require further machining to satisfy the usual installation and operation requirements.

3. In the stamping process, because the appearance of the data is not damaged, it has a good appearance quality, beautiful appearance and lubrication, which provides convenient conditions for exterior painting, electroplating, phosphating and other external treatment.

Metal stamping parts are everywhere in our lives, but we must check the quality of our purchases. After all, it is still very troublesome to buy something, so we need to check the quality of it when we buy it. I hope this article is helpful to you.
