  When it comes to the assembly and disassembly of automobile tires, perhaps the first thing that comes to people's minds is the wrench, but do you know that there are many types of wrenches, such as manual wrenches are suitable for the most primitive furniture, car tire disassembly and assembly, but it takes a lot of effort and may have been eliminated by the times. The air wrench is divided into air ratchet wrench, air wrench, cordless impact wrench and air impact wrench, the air ratchet wrench (rongpeng 7408) is used in narrow and hard-to-reach work areas (automobile engines, spark plugs, etc.), the air wrench (rongpeng R901) is used in automobile tires, engine screw assembly, etc., and the double-hammer air wrench has a larger torque output, which can be competent for the tire removal and assembly of large vehicles such as trucks and excavators, the cordless impact wrench(rongpeng R681 is used for the installation of steel structure bridges, road guardrail infrastructure, workshops, chemical equipment, etc)and the air impact wrench (rongpeng RP9563) has the highest torque among the three, but it also has a large noise, used in (large industrial equipment, truck, excavator tires, construction site structure, etc.), we are going to talk about air wrench today, taking rongpeng RP7430 as an example.

How does an air wrench work
The pneumatic impact wrench uses the air flow of compressed air to push the blades, and the blades rotate to drive the impact block, and the impact block continuously strikes the central shaft to work, generating power to form a circular rotary motion, and the connecting sleeve on the drive side tightens or disassembles the bolts
rongpeng RP7430 is a standard double hammer structure, the principle is a double hammer structure impact block, two iron blocks alternately hit, providing a higher impact rate, producing continuous and stable torque output, rongpeng RP7430 torque up to 570N.M, stable high torque output than ordinary single hammer impact wrench is more competent for the assembly and disassembly of large automobiles, working vehicle tires and engines and other large torque places, five gear torque settings, The operator can also adjust the torque gear and select the appropriate working torque to complete the corresponding work content, for example, (the moderate gear torque can be used to complete the car tire work, and the higher gear can be selected to complete the truck tire work), and the hammer block has been heat treated, has strong wear resistance, and can withstand the wear caused by the alternating impact of the two hammer blocks during work, which increases the service life. Weighing only 2.6kg, it is especially suitable for some people engaged in the auto repair industry, which can handle the maintenance work of various vehicles, and the light weight and efficient torque output can perfectly reduce the fatigue of the day's work.

The drill bit of rongpeng RP7430 pneumatic wrench is made of alloy steel, alloy steel is an excellent wear-resistant, corrosion-resistant material, when working, the drill bit should leak in the air for a long time, and the workshop is a workplace with complex chemical elements, chemicals will cause corrosion and damage to the product, and the corrosion resistance of alloy steel material completely solves this pain point, and the workshop, repair shop is usually more messy, some product debris and small stones and other substances can not be avoided, when the power is provided by compressed air, these debris will also enter the body with the air flow, It will cause damage to the product, and the rongpeng7430 air inlet is equipped with a filter, which can effectively block these debris, increase the service life of the product, and reduce the maintenance cost of the subsequent product.
