Thousands of Hammers-Percussion Wrench

I believe that everyone knows that there are many types of wrenches, and different types of wrenches have different uses. Today, I recommend a wrench-a percussion wrench. Although this kind of wrench is not common in ordinary times, it is often used in professional machine repair work. So choosing the right wrench is extremely important for work efficiency. Let's talk about the doorway of knocking the wrench.

Percussion wrench materials are mainly divided into cast iron, steel and aluminum bronze alloy, beryllium bronze alloy. The percussion wrench has the characteristics of reasonable design, stable structure, high material density, strong anti-shock ability, no folding, constant, no bending, high dimensional accuracy and durability. Percussion wrenches are integrally forged from No. 45 medium carbon steel or 40Cr steel. They are an important type of manual wrenches. Generally, the handheld end is the striking end, and the front end is the working end. Tools World Supermarket's percussion wrenches mainly include two types of percussion wrenches and percussion wrenches.

Strike open wrench is one of the large industrial tools, widely used in petroleum extraction, oil field, refining, petrochemical, chemical, power generation, shipbuilding, metallurgy, ore, machinery and other industries. Wide range of applications, durable. The percussion wrench in Taiyuan hardware tools is forged from high-quality medium-carbon steel or high-quality alloy steel. It is suitable for petroleum, chemical, metallurgy, power generation, oil refining, shipbuilding, and petrochemical industries. It is suitable for occasions where the working space is narrow and ordinary wrenches cannot be used. Used to unscrew hex head bolts or nuts. The corner is small, and it can be used where there is only a small swing angle (just turn the corner of 1/2 of the wrench), and because of the large joint surface, it can be used for strong tightening. It is used in situations where the working space is narrow and ordinary wrenches cannot be used. Used to unscrew hex head bolts or nuts. The corner is small, and it can be used where there is only a small swing angle (just turn the corner of 1/2 of the wrench), and because of the large joint surface, it can be used for strong tightening.

Although the striking box wrench is simple in structure, the material requirements are actually very high. After all, "the tool is durable, look at the material first!" The poor percussion wrenches on the market all use ordinary steel stamping, and the strength is far from being required. It is easy to be deceived if it is good enough, and it is easy to be deceived without good discrimination. A good impact wrench is usually made of 45 # high-quality carbon alloy steel forging, with good material toughness and hardness, which is perfect for the work of striking.

In addition, processing technology is also one of the important factors. The poor percussion wrench is formed by pressing the front and back parts and then welding, which is not only unsightly, the strength cannot be guaranteed, and it is easy to break. Good percussion wrenches are entirely made of die forging, which has a better appearance than free forging, and the product is stable and resistant to impact. Finally, the whole mesh belt furnace should be heat treated to give full play to the physical characteristics of the material and improve its service life.

Good products will surely have good approval. At present, the knock wrenches (including knock wrenches and knock open wrenches) in Ruijie Mall have reached the German DIN standard, and are made of high-quality 45 # carbon alloy steel as a whole. The best tool for hand.
