Rebar is one of the most important and basic building materials, which despite having sufficient knowledge of material mechanics and strength of materials, you will be well aware of its importance.
Much of what we call reinforcement is mainly due to the reinforcement of the tensile capacity of the various sections, using rebar.
Even in concrete, using rebar, we see the reinforcement of concrete and increase its tensile strength. The important point here is how to use and operate the rebar.
Undoubtedly, the most important and basic tool that participates in the rebar preparation process is the hydraulic rebar.
This versatility and attractiveness of hydraulic rebar has led us to try in a note to examine the reasons for the attractiveness of hydraulic rebar and to provide an answer to the question of why hydraulic rebar is the most popular rebar scissor model.
In the following note, while getting acquainted with the nature of this device and its different types, you will understand why hydraulic rebar cutting scissors have appeared more successful in practice, and even despite the difference in the price of electric rebar, this product is more successful. In this regard, in this note, you will encounter the following topics.
Why is cutting rebars so important?
By paying close attention to the appearance of the rebar, you will notice that it is basically necessary to use these materials to cut and bend at times. Because it is a reinforcing structure, accuracy in its length and size is important in many ways.
Certainly, the importance of accuracy in determining the length of the rebar is not in the scope of the objectives of this text, but by referring to the principles and laws of material mechanics (strength of materials) you will realize the importance of this issue.
A hydraulic rebar, or any other type, is a device that provides rebar cutting.
How many types of scissor bending and rebar cutting are there?
In order to be able to answer the question of why rebar on hydraulics is the most popular model of rebar scissors, we need to first understand that this device is basically produced and used in several types.
Bending scissors and rebar cutting will be divided into two main categories.
Manual rebar bending and cutting scissors and machine rebar bending and cutting scissors. It is very clear that in the manual model, the necessary force to make the cut will be provided by the muscles of an operator (worker).
This makes the limitations of a human physical ability outweigh the limitations of scissor bending and rebar cutting, and the tool has little cutting ability.
Although in the past this problem was partially solved by using the integration of multi-worker force, but today, along with the serious development of construction and the requirements for the construction of structures, we are witnessing a sharp increase in the diameter of rebars.
This makes it not as easy to cut and cut the rebars by the manual model as in the past. But in bending and cutting scissors, we also face two separate categories.
Electric rebar bending and cutting scissors (with gearbox)
One of the types of scissors for bending and cutting machine rebar is the electric model. Of course, using the term electric may not be very interesting because hydraulic rebar also uses electricity and the use of electricity is not a point of difference between these two types of products, but in any way, the general public is also called electric rebar.
In electric rebar bending and shearing, a single-phase or three-phase generator provides the driving force needed to move a gearbox.
This gearbox will convert the rotational force exiting the generator into the linear force required for pressure at the edge of the scissors by directing the forces.
In this way, with a completely mechanical process, the gearbox and the gear provide a lot of force for cutting the rebar.
In the case of hydraulic rebar cutters, however, the difference is in how the power is transmitted from the motor to the scissor bore.
Note that in the hydraulic rebar, the necessary driving force will be provided by a single-phase or three-phase generator, and in this respect there is no difference with the gearbox model.
However, in hydraulic rebar cutters, oil is used as a fluid for power transmission. In this process, the output power of the engine is spent on intense contraction and compression of the oily fluid, and through this, the necessary force to move a jack will be provided.
The hydraulic jack allows you to multiply the output power of the engine.
This is the main feature of the hydraulic jack. Instead of the gearbox, the hydraulic jack transmits the necessary force to the edge of the scissors, and eventually the whole system will be targeted; Rebar cutting.
Now, despite the explanations provided, one can ask why rebar on hydraulics is the most popular model of rebar scissors.
Reasons for successful hydraulic rebar
Certainly, when we talk about the success and widespread use of hydraulic rebars, we mean the success of this device compared to the type of gearbox, because obviously both types of machines are superior to the manual type.
This issue does not need careful consideration (or at least in the circle we do not have goals in mind).
Accordingly, in comparing the hydraulic rebar with the gearbox model, the following points should be mentioned.
Hydraulic rebar cutter has a significant advantage in terms of ease of transport and handling.
The construction and arrangement of parts in the hydraulic rebar has made the final size and weight of this device much less than the electric model, and this is one of the reasons why this product is attractive to users.
Do not forget that the rebar cutter is one of the tools that is easy to move and is vital. The mechanical model is not suitable for displacement in terms of construction, size and dimensions.
The output force on the hydraulic rebar is very high. The use of a hydraulic structure that is based on oil fluid, has caused that in equal conditions in terms of generator power, the power and strength of the rebar on the hydraulic compared to the type of gearbox. This is evident in the cutting of thicker rebars.
Due to the use of oil fluid instead of bearing and transmitting force to the mechanical parts and the constant physical contact of the parts, the hydraulic rebar enables the transfer of force in the fluid flow bed.
This means that the life of hydraulic rebars is longer than other types of machines. The less pressure the parts can withstand directly and physically, the longer they will last.
The use of less mechanical parts and details has other benefits. Reducing the number of small and minor parts, despite the elimination of the gearbox in the hydraulic rebar, has made the repair of the device much easier.
The main problems of hydraulic rebars are related to damage to the oil pump, which will be easily solved by replacement.
