What are the commonly used wrenches?

The most commonly used manual torque wrenches, in addition to electric torque wrenches, pneumatic torque wrenches, etc.

Structural torque wrenches are also called torque meters and torque screwdrivers. It is designed based on the bending principle of the beam, the bending principle of the torsion bar and the compression principle of the coil spring, and it can measure the torque acting on the nut Ratchet Wrenches Factory.

Ratchet Tools Factory

There are two types of torque wrenches: flat type and dial type. The torque wrench has a long elastic rod. One end is equipped with a handle, and the other end is equipped with a square or hexagonal head. A replaceable sleeve is fitted on the square or hexagonal head and is clamped by a steel ball. There is also a long pointer on the top. The scale plate is fixed on the handle base, and the scale value of each grid is 1N (or kg/m).

Before use, adjust the indicator installed on the wrench to the required torque, and then pull the wrench. When the predetermined torque is reached, the pointer on the indicator will rotate to the pin shaft, and finally the pointer collides with the pin shaft. , To inform the operator through speaker signal or sensor signal.

What should I do if the hydraulic wrench is stuck and cannot be removed

What should I do if the hydraulic wrench is stuck and cannot be removed from the nut during use. The solution on site is the M64 bolt on the water pump, the nut is 95mm opposite to the side. The on-site use is mainly to loosen the bolt with a hydraulic wrench. I saw that the pump station kept pressing, but the hydraulic wrench did not turn, and after the pressure was relieved, the hydraulic wrench And the sleeve cannot be removed from the nut. If you smash it with a sledgehammer, the hydraulic wrench will not only still be unable to be removed, but it will also damage the wrench and cause personal injury.

In fact, in this situation, there is a small, inconspicuous component on the driven hydraulic wrench, which everyone will not pay attention to. That is to release the trigger. The position of releasing the trigger is one on each side of the hydraulic wrench. Many customers must have thought that the release of the trigger is a non-return function, but this "small thing" has a bigger effect that is when the hydraulic wrench is stuck and cannot be removed, it can be easily removed by pushing the release trigger. Removed the jammed wrench Ratchet Tools Factory.

The specific method is, before the hydraulic wrench is stuck, what is the pressure on the hydraulic pump station, and then add the pressure on the pump station to the previous pressure, for example, the working pressure of 30Mpa before, then the pump station Adjust the pressure to 35Mpa, keep pressing the high-pressure oil inlet button without releasing it, and at the same time, pull down the release trigger by hand, and the hydraulic wrench can be removed from the nut smoothly. If the maximum pressure of 70Mpa used by the customer is stuck before, then the pressure should not be adjusted, but the pressure of 70Mpa should be used, and then the trigger should be released.

By the way, when you release the trigger, you must move it with your hand. Never use other tools to move or beat it. This is not advisable.

What is the difference between ratchet wrenches

Ratchet Wrenches

The ratchet socket wrench is connected by the main torx socket and the slave torx socket of different specifications and sizes through the female key and the male key of the hinged key. Because a plum blossom sleeve has two specifications of plum blossom-shaped through holes.

The movable trigger can easily adjust the use angle of the wrench. This kind of wrench is used for the tightening operation of screws, and has the characteristics of strong applicability, convenient use and low cost.

Torque wrench-also called torque wrench or torque wrench. Torque is the product of force and distance. When tightening screws, bolts, nuts and other threaded fasteners, the applied torque needs to be controlled to ensure that the threads are tightened and not due to excessive torque. The thread is broken, so use a torque wrench to operate. First set an upper limit of the required torque value. When the applied torque reaches the set value, the wrench will make a "click" sound or the wrench connection will bend a little angle, which means that it has been tightened and no more force is required.

The difference is that the torque of the torque wrench can be set.

The principle of a torque wrench (torque wrench) making a click sound is very simple and can be divided into the following Steps to understand: 1. After the torque wrench makes a "click" sound, it indicates that the torque value you requested has been reached [2]; 2. The "Kata" issued by the torque wrench is produced by its internal torque release structure, which is divided into three structures: pressure spring, torque release joint, and torque ejector rod [2].

The principle of kata sound

First set the required torque value on the torque wrench (the spring is sleeved on the top rod to apply pressure to the torque release joint), lock the torque wrench, and start tightening the bolts. When the bolt reaches the torque value (when the torsion force is greater than the pressure of the spring), the effect of instantaneous disconnection will occur. At the moment when the disjointed effect is produced, the joints are knocked, and the metal shell of the wrench makes a "click" sound. This confirms the reminder function of reaching the torque value (actually, it is the same as the principle that our arm joints are bent at 15 degrees and placed in the iron pipe and then the steel pipe is immediately straightened).

What is the difference between ordinary wrench and ratchet wrench

In home life, besides screwdrivers, wrenches are commonly used hand tools. All kinds of wrenches are needed for installation, maintenance, and disassembly. "Adjustable wrenches, box wrenches, L-shaped wrenches, and allen wrenches" are the more commonly used wrenches, and most of these wrenches are used in the same way.

Ratchet wrenches are being used more and more for reasons such as large torque, high hardness, and convenient operation. So as a wrench, how to choose ordinary manual wrench and ratchet wrench?

Ordinary manual wrenches are simple in mechanism, using the principle of leverage to turn bolts, screws, nuts, etc. The ratchet wrench mechanism is more complicated than ordinary wrenches.Ratchet Wrenches for sale A circlip, a pawl, a spring and a ratchet are arranged in the containing space of the head of the main body. The ratchet is composed of the main body of the ratchet and a spacer. The spacer is a peripheral with a concave ring. The groove is a circular ring, and the spacer is sleeved on one side of the ratchet body.

Comparison of wrench features

Ordinary manual wrenches are easy to operate and labor intensive. The ratchet wrench can be used to rotate bolts or nuts placed in narrow or inaccessible positions, and the ratchet wrench is rotatably connected to the end of the operating rod.

How to choose a wrench?

To choose according to the environment of use, the tension and torque of different types of wrenches are different, and the strength of friction generated during use is also different. The swintool ratchet wrench integrates ordinary manual wrenches and ratchets, covering most of the scenes of using wrenches in home life and satisfying everyone's habit of using hand tools.

What are the precautions for the use and operation of electric wrenches

1. Confirm whether the power supply connected to the site matches the nameplate of the electric wrench. Whether there is a leakage protector connected.

2. Choose a matching sleeve according to the size of the nut and install it properly Ratchet Wrenches.

3. Make sure that the switch on the electric wrench is disconnected before powering on, otherwise the electric wrench will rotate unexpectedly when the plug is inserted into the power socket, which may cause personal injury.

4. If the work site is far away from the power source and the cable needs to be extended, use a qualified extension cable with sufficient capacity. If the extension cable passes through the pedestrian walkway, it should be elevated or take measures to prevent the cable from being crushed and damaged.

5. Try to find the supporting point of the reverse force distance when using it to prevent the reaction force from hurting people.

6. When the carbon spark of the motor is found to be abnormal during use, it should stop working immediately, check and deal with it, and eliminate the fault. In addition, the carbon brush must be kept clean.

7. Standing on a ladder or working at a height should take measures for falling from a height, and the ladder should be supported by ground personnel.

How to install the screws on the license plate?

Everyone who owns a car knows that our car needs a license plate, but in the process of getting a license plate, it also requires a lot of attention to the details. Some novice drivers don’t understand the points and fines, so today we take this opportunity to show everyone Let’s take a look at how to get the license plate, and what details need to be paid attention to. When the previous new traffic law was just changed, it required four fixing screws to be attached to the license plate

But the original designer of the old car only had two fixed DIN 1478 turnbuckles, so when you put four on, the next two are just like a look, so it will appear later, if there are two small holes, only two small holes are needed. If there are 4 holes, 4 holes must be installed. My car can only have two fixing screws, so the license plate and the car will make some noises over time.

So I first cleaned the car a little bit and put on a double-sided tape, which can avoid noise when the license plate is loose. When the double-sided tape is applied, the license plate is aligned to the symptom, and then it can be attached by pressing it. Now, after attaching it, we will attach the fixed screw. When the screw is fixed, there will be a protrusion on the side of the screw cap.

The design of this structure prevents it from being released when it is sealed, so it has a certain anti-theft and anti-demolition effect. When unloading the license plate at the vehicle tube,Heavy duty ratchet turnbuckle tools for sale it is necessary to clamp the screw cap with a large clip and then unscrew it. When screwing the screw, we must first insert it and then tighten the screw, and then tighten the screw. Personally, I will tighten the license plate very tightly to ensure that it will not loosen, and then it is considered to be tightened.

When applying the license plate on the back, follow the same steps as the previous one. Then just screw up the screws. Since the screws on the back were cut a few days ago, the holes are too big, so you can only plug the holes with a little waterproof glue. To avoid water infiltration in this place, we can finally put Gu Feng card on it.

We must pay attention to a few details when registering the license, that is, do not cover the white border, because the license frame is required to not cover the white border, so we must expose the white border when the license is registered, otherwise it will Punishment by blocking the number plate, even deducting points. The second is to get him upright, because it will be very ugly if it is crooked, and the third is to not have anything stuck in the screw hole. If it is stuck, it will be taken out for him.

The last point is that you are advised to put some foam glue on the license plate, or use some double-sided tape like me, to prevent the loosening of the license plate and the friction of the car in the later stage to cause some noise. All of these have been achieved, I think your license plate It's completely good, so don't underestimate the license. This is also asked by many universities.
