Q:How do you adjust the pressure on the pressure gauge and the tightening torque of the bolt on the hydraulic wrench?
How big is the diameter of the cylinder of your hydraulic wrench? How much pressure is directly related to this?!
Q:How can the electric drill chuck be removed?
With a suitable size of the pipe, just hold the drill clamp coat, the middle part of the hammer and the shell separation, inside of the thread is two disc, three catch rearranged into thread, plus fixed coat.
Q:What's the effect of a wrench in life?
6. socket wrench: it is composed of a plurality of sockets with six corners or twelve corners and is provided with various attachments, such as a handle, a connecting rod, etc., and is especially suitable for screwing bolts or nuts with very small positions or very deep depressions.7. inner six angle wrench: a L shaped six angle wrench, used exclusively for screwing six angle screws. The size of the inner six angle wrench is based on the six side dimensions. The size of the bolt has the national standard. Application: used for fastening or dismounting the round nuts on machine tools, vehicles and mechanical equipment.8. torque wrench: it can show the applied torque when screwing the bolt or nut; or when the applied torque reaches the specified value, it will send out light or sound signals. Torque wrench is suitable for the torque size is clearly defined.
Q:How to remove the small wrench on the instrument panel?
Very simple, and the same passage 1, press the right button on the instrument, turn the ignition switch. 2, relax the button, turn the left key to the right, and turn the light to zero.
Q:What material is the best inside six corner wrench?
S2 material wrench hardness is highest.
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. (machining process omitted)
Q:How can the heat treatment process be formulated?
45 steel quenching temperature at A3+ (30~50) DEG C, in practical operation, usually take the upper limit. High quenching temperature can accelerate the workpiece heating, reduce the surface oxidation, and improve the work efficiency. Adequate homogenization time is required for the homogenization of austenite in the workpiece. If the actual amount of furnace installed is large, it is necessary to extend the insulation time properly. Otherwise, there might be a lack of hardness due to uneven heating. However, when the holding time is too long, the defects of coarse grain and serious decarburization of oxidation and decarburization will also be affected, which will affect the quality of quenching. We believe that if the amount of furnace is larger than the process documents, the heating and insulation time should be extended by 1/5.
Q:What is the ball head at the end of the ball head L type six angle wrench?
You can use the ball head when the screw and the inner six angle wrench can not be placed in a straight line.
Q:What's the difference between an electric wrench 28V and an 32V?
Because the current lithium wrench on the market are 18V, the full power of the highest voltage of 21V, 32V is a virtual standard, 28V is also a virtual target. The actual battery pack contains 10 18650 electric cores, a single 18650 of the core is 3.6V, a row of 5 series to get 18V voltage, and then the two lines in parallel, to get the capacity of the battery pack. You can use a multimeter to measure the amount of electricity, when the amount of electricity is 18V, full of electricity when the maximum voltage is 21V.
Q:It's powerful. Why isn't the wrench strong?
The beginning is mainly rely on the wrist, also need some skills, such as hand from their near some distance, it will pull the opponent's hand to his side pull, not straight pull, but to his palm tilt, as far as possible to his chest, called the other hand don't hold the opponent's table
