How is the ratchet wrench made?

What is a ratchet wrench?
Ratchet wrench is a manual screw tightening tool, mainly used to rotate bolts or nuts in narrow or difficult to access positions. Through the connection of the sleeve, the ratchet wrench can easily cope with various work needs.

Manufacturing process of ratchet wrench:
The main body of the ratchet wrench is forged from a solid steel rod. The forging press presses the heated steel rod into the basic shape of the wrench, and then uses different dies to remove the excess edges. After they have cooled, use a milling machine to process the ratchet cavity. The gear assembly should be placed in the inner cavity, which is mainly responsible for the internal operation of the ratchet. The flowing white liquid is the coolant, which can cool the workpiece and the tool in time. After processing the inner cavity, use a lathe to perform fine processing on the handle and end of the wrench. Cut off the excess part to facilitate subsequent installation of the handle. Then use a grinding wheel to smooth the wrench to remove the burrs. Pressing such a groove on the handle can make the handle installation more secure.

In order to make wrenches more durable, they need to be heat treated. After that, a ceramic abrasive is used for polishing. The wrench is going to be electroplated. The plating is nickel and chromium. The two plating layers can prevent the wrench from rusting. It can also make it have a beautiful appearance. Apply lubricating oil, and now begin to install the gear assembly in the ratchet inner cavity. Install the switch first, it can control the operation of the ratchet. Put the stability bead into the ratchet gear and clamp it tightly with a punching machine. Put the gear into the inner cavity of the ratchet, and then install the rest of the small parts. They can be combined together to easily tighten or loosen bolts or nuts. Put the sealing ring in the cover plate. Then tighten the cover screws. Install the plastic grip and this ratchet wrench is complete.
