In the field of metal processing, hydraulic shearing machine plays a very important role. It can cut metal plates efficiently and accurately to meet different production needs. However, there are many types of hydraulic shearing machines on the market with different specifications. How to choose a hydraulic shearing machine that suits you? The following are some key considerations.

Processing requirements analysis

Plate material and thickness

1. Material: First of all, we need to know the material of the metal sheet that is often processed. Common ones include ordinary carbon steel, stainless steel, aluminum alloy, etc. Plates of different materials have different characteristics such as hardness and toughness. For example, stainless steel plates are more resilient than ordinary carbon steel, and the shearing machine needs to have greater shearing force when cutting. Therefore, if the processing object is mainly made of harder or more resilient materials such as stainless steel, it is necessary to choose a hydraulic shearing machine with stronger shearing ability.

2. Thickness: Determine the maximum thickness and common thickness range of the plate in daily processing. Hydraulic shearing machines have their rated maximum shearing thickness indicators. If you often need to shear thicker plates, you must choose a model with a maximum shearing thickness that can meet your needs, so as to avoid the situation where you cannot shear or excessively wear out the equipment; at the same time, the shearing accuracy requirements for thinner plates will also affect the choice of shearing machines. Some high-end shearing machines can ensure better cut flatness and dimensional accuracy when shearing thin plates.

Shear size requirements

Consider the maximum length and width of the plate to be cut. The shearing machine's work surface size and throat depth and other parameters determine the maximum specifications of the plate it can process. For example, if you need to cut a wider plate, you should choose a shearing machine with a wider work surface and a suitable throat depth to ensure that the plate can be placed completely and the shearing operation can be carried out smoothly, avoiding the inability to meet the production task due to size limitations.

Production efficiency requirements

1. Single shearing frequency: Understand the speed requirements for single shearing in your production process, that is, the number of shearing times you expect per minute. This depends on factors such as the movement speed of the shearing machine's knife frame and the response speed of the hydraulic system. For companies with large-scale production, large orders, and high shearing efficiency requirements, they should give priority to hydraulic shearing machine models with fast knife frame reciprocating speed and high-frequency shearing.

2. Batch processing needs: If you often need to process plates of the same specifications in batches, a hydraulic shearing machine with automation functions (such as automatic feeding device, programmed batch shearing function, etc.) can greatly improve production efficiency and reduce manual operation time and errors. Therefore, it is necessary to decide whether to choose equipment with such functions based on whether there is a normalized demand for batch processing.

Equipment performance considerations

Hydraulic system quality

1. Brand and quality of hydraulic components: The core power of the hydraulic shearing machine comes from the hydraulic system, and the quality of key components such as hydraulic pumps, hydraulic cylinders, and hydraulic valves is crucial. Hydraulic components from well-known brands are often more reliable in performance. For example, hydraulic components from brands such as Bosch Rexroth of Germany and Yuken of Japan have the advantages of stable pressure, good sealing, and long service life. They can ensure the stable operation of the shearing machine and reduce the probability of failure. Therefore, try to choose equipment with high-quality hydraulic components.

2. System pressure and flow: The pressure of the hydraulic system determines the shearing force of the shearing machine. The hydraulic system with appropriate pressure should be selected according to the plate thickness and material requirements analyzed above. At the same time, the flow affects the movement speed of the tool holder, which in turn affects the shearing efficiency. It is necessary to ensure that the flow can meet the expected shearing speed requirements.

Tool quality and configuration

1. Tool material: The tool is the part that directly contacts the plate and completes the shearing. Its material directly affects the durability and shearing quality of the tool. High-quality high-speed steel or carbide tools usually have higher hardness, wear resistance and toughness, can maintain a sharp edge, and are not easily deformed or damaged after long-term shearing. They can ensure good cutting quality when cutting plates of different materials, so you should pay attention to the material selection of the tool.

2. Convenience of tool replacement: During long-term use, the tool will inevitably wear out and need to be replaced. Choosing a shearing machine with convenient and quick tool replacement can reduce equipment downtime and improve production continuity. For example, a machine with a quick tool change device or a reasonable structural design that is easy to disassemble and install the tool is more worthy of consideration.

Precision control capability

1. Positioning accuracy: For plate processing that requires precise cutting size, the positioning accuracy of the shearing machine is very important. It depends on factors such as the mechanical transmission structure accuracy of the equipment and the control accuracy of the CNC system (if any). For example, a shearing machine that uses high-precision screw drive, linear guides and other mechanical components and is equipped with a precise CNC system for positioning control can control the shearing size error within a very small range and meet the needs of high-precision processing.

2. Parallelism and verticality: The parallelism between the tool holder and the workbench and the verticality between the blades are related to the flatness and angle accuracy of the plate cut after shearing. High-quality hydraulic shearing machines will strictly control these precision indicators during the manufacturing and assembly process. When purchasing, you can check the factory accuracy test report of the equipment or observe the test cutting effect on site to evaluate its precision control ability.

Convenience of operation and maintenance

Ease of use of CNC system (if equipped with CNC system)

1. Programming operation interface: If you choose a CNC hydraulic shearing machine, the programming operation interface of its CNC system should be simple and intuitive, easy to understand and operate, and it is best to have a graphical programming function. The operator can quickly input shearing parameters and set shearing tasks without complex programming knowledge. This can reduce the requirements for the operator's professional skills and improve the efficiency of equipment use.

2. Functional richness: A CNC system with practical functions such as automatic calculation of cutting length, automatic compensation of tool wear, fault diagnosis prompts, etc. can better assist production and reduce operational errors. Therefore, it is necessary to comprehensively evaluate whether the functions provided by the CNC system meet production needs.

Equipment maintainability

1. Structural design is easy for maintenance: The overall structure of the equipment should be easy to open, inspect and repair. For example, the various components of the hydraulic system should be reasonably arranged, with enough space for maintenance personnel to perform inspections and replace components. The connection method of mechanical parts is simple and easy to understand, and easy to disassemble and reassemble. In this way, when the equipment fails, the problem can be quickly located and repaired, reducing downtime for maintenance.

2. Maintenance requirements: Understand the daily maintenance content and cycle of the equipment, and choose shearing machines that are relatively simple to maintain and have easy access to the required maintenance materials and tools. For example, some shearing machines have a long hydraulic oil replacement cycle, and the hydraulic oil filter and other wearing parts are easy to replace, which can reduce the cost and difficulty of equipment operation and maintenance.

Brand and after-sales service

Brand reputation

Choose brands with good reputation and long production history in the industry. Such brands often rely on years of technical accumulation and market testing, and their product quality is more guaranteed. They are more mature in equipment research and development, production technology, etc., and can provide stable and reliable hydraulic shearing machine products to reduce purchase risks. You can learn about the reputation of different brands by consulting industry information and consulting peers.

After-sales service guarantee

1. Service outlet coverage: Ensure that the selected brand has a complete after-sales service outlet in the local or surrounding areas, so that it can respond promptly when the equipment fails and dispatch professional maintenance personnel to provide door-to-door service. Timely and effective after-sales service can minimize the impact of equipment downtime on production.

2. Timely supply of spare parts: Understand the brand's supply of equipment spare parts and whether it can quickly provide original high-quality spare parts, such as hydraulic components, cutting tools and other common spare parts, to ensure that the damaged parts can be replaced as soon as possible during equipment maintenance and resume normal operation.

Budget Factors

Finally, you should choose a hydraulic shearing machine based on your own budget. The prices of shearing machines of different brands, different configurations, and different functions vary greatly. On the basis of meeting the processing requirements, performance requirements, operation and maintenance convenience, and after-sales service mentioned above, you should reasonably weigh the price factors, avoid blindly pursuing high-end configurations and exceeding the budget, and do not choose too low configurations to save costs and fail to meet actual production needs. Strive to select the most cost-effective hydraulic shearing machine within the budget.

In short, choosing a hydraulic shearing machine requires comprehensive consideration of many factors, carefully analyzing your own processing needs, evaluating the various performance of the equipment, paying attention to the convenience of operation and maintenance, and brand after-sales service, etc., so that you can choose a hydraulic shearing machine that fits your own production situation, efficient and reliable, and lay a solid foundation for the smooth development of metal sheet processing business.
