Pipe Wrench Manufacturing Process
A wrench manufacturing process for manufacturing a rotational-tube wrench comprises the steps of forging, annealing, rolling, punching, drawing, polishing, surface grinding, CNC rough cutting, thermal treatment, vibrating, electroplating, CNC fine cutting and assembling.
What is a Pipe Wrench?
A pipe wrench is an adjustable wrench designed for use on pipelines. Pipe wrenches are most commonly used on threaded pipes made of galvanized steel, black iron, or other comparable metals. A pipe wrench contains two serrated jaws that, when tightened, dig into the pipe to provide hold. The top serrated jaw moves up and down to accommodate different pipe sizes. A pipe wrench’s teeth only grasp when turned in one direction (as seen above), hence it functions similarly to a ratchet wrench.
Here are the fundamental components of a pipe wrench:
- Hook Jaw
- Nut
- Body
- Pin
- Heel Jaw
- Spring Assembly (Not shown)
Some pipe wrenches, although uncommon, include a separate head assembly that may be attached to the body. Pipe wrenches, often known as monkey wrenches, are used by plumbers, drillers, and many other crafts that operate with threaded pipes.
The Complete Guide Pipe Wrench Manufacturing Process
Our guide explains everything you need to know about Pipe Wrench Manufacturing Process.
1.Forming a roughcast of the wrench by means of thermal forging;
2.Annealing said roughcast of the wrench so as to soften the roughcast to facilitate subsequent processing;
3.performed a rolling process; namely to rub said roughcast of the wrench against sand granules in a rolling barrel, so as to remove carbide materials attached on said roughcast during said step of annealing;
4.Shaping said roughcast of the wrench to a predetermined shape;
5.CNC rough cutting, whereby a receptacle space in a front section of said roughcast of a wrench is cut to attain a predetermined size;
6.cutting a receptacle space in a front section of said roughcast of the wrench to has a predetermined size by CNC rough cutting or MC cutting;
7.Enhancing the structural toughness of said roughcast of the wrench by a heating process so that the structure is capable of resisting the stress caused by twisting a fixed object;
8.Fining a surface of said roughcast of the wrench by chemical vibrations so that the roughcast is suitable for being electroplated;
9.Coating said surface of said roughcast of the wrench with a protective layer to resist oxidation and attrition;
10.Eliminating slight deformations due to said step of thermal treatment, of said receptacle space of said roughcast of a wrench by performing CNC cutting or MC fine cutting so that said receptacle space fits required degree of roundness, and an inner wall of said receptacle space is left with fine tool marks for providing a better frictional effect with a part set to be installed therein;
11.Coupling said roughcast of the wrench with said part set within said receptacle space thereof and being then locking said roughcast with said part set by a locking member.
Pipe Wrench Manufacturing Process FAQs
The prior art’s wrench manufacturing procedures include (1) forging, (2) annealing, (3) rolling, (4) punching, (5) drawing, (6) polishing, (7) surface grinding, (8) vibrating, and (9) assembly. The wrench is first formed during the forging process.
Pipe wrenches are classed according to the length of the handle. They are often available in sizes ranging from 6 inches (150 mm) to 48 inches (1,200 mm) and greater. They are typically fashioned from forged steel. Today, aluminum can be used to reduce the weight of the wrench’s body, but the teeth and jaw remain steel.
Insert the screwdriver tip into the screw head and spin the handle clockwise while exerting pressure to keep the tip securely in place. Continue to spin the screwdriver firmly, making sure the screw is straight as it enters the material.
