Q:How to repair the air (pneumatic wrench)

The air is used in the compressed air, compressed air enters the air cylinder to drive after the inside of the impeller and impeller rotating power, and then drive against parts connected by hammering similar movement, after each keystroke to screw up or down. It is an efficient and safe pneumatic wrench for dismounting screws.

Q:How do you read scale values for torque wrenches?

It's a strange question!!! There are many kinds, and if it is the simplest digital display, it can be displayed directly. If it is a dial, it can be read directly. Of course, if I think the most accurate words you need to click the wrench, a preset torque, so when reaching the cracking torque, rang, you get the required torque, ha ha!!! If ok, don't forget to meet me!

Q:Special electric wrench timberman what brand is best?

There are many kinds of electric wrenches, and the electric wrench used for the scaffolding is very different from the electric wrenches used in the automobile industry and the machinery industry. The difference is due to the special nature of the industry.

Q:What is the difference between worm gear and worm wheel?

Worm gears are commonly used to transfer motion and power between two intersecting shafts. The worm gear and the worm in the middle plane are equivalent to the gear and the rack, and the worm is similar to the screw shape.

Q:What's the effect of a wrench in life?

Hook wrench: also known as the crescent wrench for screwing thickness restricted flat nut etc..

Q:How big is the triangle spanner on the street light?

8mm corresponds to the screw 10mm of M6-M8, corresponding to the screw M8-M10 of 12mm, corresponding to the screw of M10

Q:What is the difference between pneumatic sleeve wrench specification 1/2 and 3/4?

The utility model relates to a steel connecting sleeve, which is a special product used for mechanical connection of steel bars, and is divided into a cold extruding sleeve, a taper threaded sleeve and a straight threaded sleeve.(1) according to the size (mean four square size): "1/4, 3/8", 1/2 "three specifications," is the meaning of "equal to 1 inches, 25.4MM(2) according to length: long sleeve, short sleeve, E sleeve(3) press the edge: 6 corners, 12 corners(4) appearance: single channel and double channel; knurling; cylinder; nickel plating and etc.(5) use: manual and pneumatic wrench socket wrench (black chromium molybdenum) branch

Q:Is the inner six angle spanner bent with six angles carbon steel?

Most of our factory is using their own six angle wrench, material 45 steel, round bar material, milling six sides, bending quenching HRC45 - 50, very easy to use. Later to buy a set of outside market, bluing nicely, you encounter a situation I have encountered, but if I buy good quenching as well, of course, also have the opposite, overquenching, easy to break. Now the domestic market to buy things to dragons and fishes jumbled together, have some experience, buy six square wrench, with a small file, and a slip, hardness enough to be moved, and the hardness is not enough, do not buy.

Q:24, six angle screw with a big wrench?

How much wrench using six screw bolts or six angle angle, because the manufacturers of the machining error is relatively large, uneven in quality, so there is no absolute standard, currently recognized in mechanical processing industry and wrench size thread specification table,

Q:The process of making an ordinary open-ended wrench requires material and heat treatment

The blank after the rough machining after quenching, good milling opening angle of 780 DEG C after heating, in salt water (local spanner mouth) quenching, tempering 250 DEG ~350 deg. This will ensure that the wrench has a certain degree of hardness, wear and tear does not hurt the nut, wrench the rest of the parts have a certain toughness, can withstand torsion load.
