Professional Forging Hammer Manufacturer in China

Anyang forging Press Machinery Since 1956

An opening or a sleeve hole for holding a bolt or nut is arranged at one or both ends of the wrench handle. When using, an external force is applied to the handle along the thread rotation direction, and the bolt or nut can be turned. Although the structure of spanner is simple, it plays an important role in people's daily life.
At present, there are two kinds of wrench spanner manufacturing processes: one is casting, the other is wrench spanner forging process.

Is Spanner / Wrench Cast or Forged?

1, Spanner wrench casting process

casting picture

Melt the bar into liquid state, then pour it into the die cavity with spanner shape, and wait for it to solidify to form a complete spanner.
Disadvantages of cast spanner
The hardness and wear resistance of the cast spanner are relatively poor. If you want to increase the hardness and wear resistance, you need to add chromium (CR), but the price of chromium is very high, adding chromium will increase the cost of the spanner, so that the economic growth of the cast spanner in the market will decrease.

2, Spanner wrench forging process
Heat the bar, and then put it on the closed die drop forging hammer or other die forging equipment for forging. After initial forging and precision forging, the bar can be directly forged into spanner or wrench.
Advantages of spanner wrench forging process:
Because of the high speed of forging hammer and the high variation of wrench shape, the internal structure of wrench is fully changed and the forging density is increased. Therefore, the spanner wrench forged by CNC closed die drop forging hammer has high hardness and strong wear resistance.

Spanner Wrench Forging Is Better than Casting

The forging surface quality is higher than the casting quality, and the forging streamline is that the bearing load of the forging can be greater, so the forging advantage of hardware wrench manufacturing is greater than the casting process.

 

Closed Die Drop Forging Hammer for Spanner Wrench Forging


CNC full hydraulic closed die drop forging hammer is a modern program-controlled precision forging equipment, controlled by PLC, with high precision; forging energy can be digitally controlled, which is the main forging equipment for a series of precision forgings such as automobiles, aerospace, aviation, hand tools, motorcycles, etc. CNC die forging hammer can also cooperate with robot to form a full-automatic production line, reduce labor costs, save costs for enterprises, and make forgings have more market advantages.
Anyang Forging Group is the largest manufacturer of CNC closed die drop forging hammer and program-controlled precision forging equipment in China. It is the drafting and customization unit of national standard of CNC drop forging hammer. At present, the forging equipment produced by Anyang forging Press has been exported to 74 countries in the world.
