Core components:
1. Blade parts
Moving blade and static blade: This is the key component of hydraulic olecranon scissors to achieve the shear function. The moving blade is usually driven by the hydraulic system to carry out reciprocating movement and complete the shearing action with the static blade. They are generally made of high-strength wear-resistant steel, such as high-quality alloy tool steel, such as Cr12MoV. This steel has high hardness, high strength and good wear resistance, which can ensure that the blade is not easy to deform and wear during the frequent shearing process, thus ensuring the shear effect and service life.
Demolition Shear Blade shape design: The blade shape of the blade has been specially designed, and its shape is similar to the eagle mouth, which is also the origin of the name "eagle mouth scissors". The olecrane-shaped blade focuses the shear force, biting into and cutting through metal material more effectively. In the shearing process, the blade first contacts the metal structure, and the shear force is transferred to the metal through the wedge-shaped design, causing the metal to gradually deform until it is cut.
2. Hydraulic system
Hydraulic pump: Hydraulic pump is the power source of the hydraulic system, which converts mechanical energy into hydraulic energy. In hydraulic olecranon shears, axial piston pumps or gear pumps are usually used. The axial piston pump has the advantages of high pressure, convenient flow adjustment, etc., which can provide enough power for the olecon shear to cut thick metal materials; The gear pump has a simple structure and low cost, and is suitable for some small olecranon shears whose pressure requirements are not particularly high. The working pressure and flow of the hydraulic pump determine the shear force and shear speed of the olecranon shear.
Excavator Shear Hydraulic cylinder: Hydraulic cylinder is responsible for converting hydraulic energy into mechanical energy, driving the blade to shear action. It is composed of cylinder, piston, piston rod and other parts. The cylinder is generally made of high-strength seamless steel pipe to withstand higher pressure; The piston and piston rod need to have good sealing and wear resistance to prevent hydraulic oil leakage and ensure smooth movement. Through the hydraulic oil in the hydraulic cylinder to push the piston and piston rod movement, so as to drive the blade to achieve shear.
Hydraulic valve: Hydraulic valve plays a role in controlling the flow direction, pressure and flow of hydraulic oil in the hydraulic system. It mainly includes reversing valve, relief valve and throttle valve. The reversing valve is used to control the movement direction of the hydraulic cylinder and realize the reciprocating shear action of the moving blade. The relief valve can prevent the system pressure from being too high. When the system pressure exceeds the set value, the relief valve will open, and the excess hydraulic oil will be discharged back to the tank to protect the system safety; The throttle valve can adjust the flow of hydraulic oil to control the shear speed of the blade.
Demolition Shears3. Connect and secure components
Rotary device: hydraulic beak scissors usually need to be installed on the excavator and other equipment, rotary device can make the beak scissors in a certain Angle range flexible rotation, convenient from different directions to shear operation. Rotary device is generally composed of rotary support and drive motor or hydraulic motor. The slewing support can bear the weight and shear force of the olecranon shears to ensure its stable rotation; The drive motor or hydraulic motor provides rotary power, allowing the shears to quickly adjust the direction according to the work needs.
Mounting bracket: The mounting bracket is the part that firmly fixes the hydraulic beak scissors to the main equipment. It needs to fit closely with the connecting parts of the host equipment, and has enough strength and stiffness to withstand the reaction forces during shearing. The mounting bracket is generally made of high-strength steel plate welding, and its shape and size are designed according to the model of the host equipment and the installation requirements of the eagle shear.
Hydraulic Metal Shears For Excavator
Functional advantage
1. High efficiency: The shear speed of the hydraulic olecranon shear is relatively fast. Taking scrap metal recycling as an example, it can break down large scrap metal structures (such as the frame of a scrapped car) into smaller parts in a short time, greatly improving the efficiency of scrap metal treatment.
2. Strong adaptability: It can cut a variety of shapes and sizes of metal materials. Whether it is a round metal pipe, a square metal profile, or an irregularly shaped scrap metal part, the hydraulic olecranon shear can flexibly adjust the shear mode according to the shape and size of the material, and effectively cut.
3. Easy to operate: Usually the hydraulic beak scissors is installed on the excavator and other common construction machinery, the operator can use the excavator's operation control system to control the action of the beak scissors. After simple training, the operator can master the operation skills of the olecranon scissors and carry out various cutting operations.
