Metal Gantry Shear

Metal gantry shears: essential equipment for shearing and processing of metal waste

In the field of metal processing and recycling, metal gantry shears have become important equipment for processing various types of metal plates, profiles and other waste materials with their powerful shearing ability, providing efficient solutions for the reduction, packaging and reprocessing of metal waste.

The metal gantry shears produced by our factory have the following characteristics:

1. Structural composition: stable structure, bearing strong shearing force

The structure of the metal gantry shears is as its name suggests, presenting a stable form similar to "gantry". It is mainly composed of a frame, a knife holder, an upper knife, a lower knife, a hydraulic system, an electrical control system and a feeding device. The frame is the foundation of the entire equipment. It is welded with high-strength steel plates. After aging treatment to eliminate internal stress, it ensures that it has sufficient rigidity and stability to withstand the huge pressure generated during the shearing process.

The knife holder is installed on the frame and can move up and down under the drive of the hydraulic system. The upper knife is fixed on the knife holder, and the lower knife is fixed on the workbench of the frame. The blades of the upper and lower knives are made of high-strength alloy tool steel. After precision processing and heat treatment, they have extremely high hardness and wear resistance, ensuring the sharpness and service life of the shearing edge. The hydraulic system is the power core of the metal gantry shear. It consists of hydraulic pumps, hydraulic cylinders, hydraulic valves and other components, which can provide strong driving force. The electrical control system is responsible for controlling the operation of the equipment to achieve automatic operation and safety protection. The feeding device can be set as needed, such as conveyor belts, push cylinders, etc., to accurately feed metal materials into the shearing area. ​

2. Working principle: hydraulic drive, instant strong shearing​
The working principle of the metal gantry shear is based on the strong pressure generated by hydraulic transmission. When working, the operator sends the metal material to be sheared (such as steel plates, steel pipes, scrap steel blocks, etc.) to the shearing position between the upper and lower knives through the feeding device, and adjusts the shearing length of the material. Subsequently, the equipment is started through the electrical control system, and the hydraulic pump starts to work, pressurizing the hydraulic oil and delivering it to the hydraulic cylinder.​
The hydraulic cylinder drives the knife holder downward under the action of hydraulic oil, and the upper knife descends with the knife holder, forming a shearing effect with the fixed lower knife. Under strong hydraulic pressure, the upper and lower knives instantly exert huge shearing force on the metal material to cut the metal material. After the shearing is completed, the hydraulic system reverses, and the knife holder rises and resets under the drive of the hydraulic cylinder, waiting for the next shearing operation. The whole process is fast and efficient, and the shearing of metal materials can be completed in a short time. ​

3. Performance advantages: efficient and accurate, adaptable to diverse needs ​
The metal gantry shear has many outstanding performance advantages. The most significant feature is the large shearing force. The hydraulic system can provide thousands or even tens of thousands of tons of shearing force, which can easily shear steel plates with a thickness of tens of millimeters and various high-strength metal profiles to meet the shearing needs of metal waste of different specifications. ​
High shearing efficiency is also an important advantage. The knife holder has a fast lifting speed and a short single shearing time. With the automatic feeding device, continuous and efficient shearing operations can be achieved, greatly increasing the processing capacity of metal waste.​
The good shearing accuracy is also worth mentioning. The gap between the upper and lower knives can be precisely adjusted according to the material thickness to ensure that the size of the metal blocks after shearing is neat, which is convenient for subsequent stacking, transportation and processing. ​
In addition, the equipment is easy to operate, and the electrical control system adopts a humanized design. The operator can complete various operations through buttons or touch screens. The equipment runs stably and reliably, with a low failure rate and easy maintenance. At the same time, the equipment is equipped with complete safety protection devices, such as emergency stop buttons, overload protection, hand guards, etc., to ensure the safety of operators. ​

4. Application scenarios: widely used in the field of metal processing ​
Metal gantry shears are widely used in many fields. In steel mills and metal processing plants, it can be used to shear scraps and scrap steel billets generated during the production process, making them reusable furnace materials; in the scrap metal recycling industry, it can shear various recycled scrap steel, scrap iron, scrap non-ferrous metal profiles, etc., and cut them into required lengths for easy transportation and smelting; in large manufacturing companies such as shipyards and automobile factories, it can be used to shear the remaining materials and waste of large metal components to achieve rapid processing and resource recycling of waste in the factory. ​
Through the processing of metal gantry shears, the originally large and messy metal waste is sheared into regular small pieces or short segments, which not only reduces storage space and transportation costs, but also creates favorable conditions for the recycling of metal resources and promotes the development of the circular economy. ​
