介绍
Sheet metal fabrication is an essential manufacturing process that involves cutting, bending and forming sheet metal parts into various shapes and sizes. Sheet metal is a versatile material used in various industries including automotive, aerospace, construction and electronics due to its durability, strength and corrosion resistance. One of the most critical tools in sheet metal processing is the NC plate bending machine, which has revolutionized the industry by providing precise, efficient and versatile bending operations.

cutting method
Cutting is the first step in sheet metal processing, and there are many methods for sheet metal cutting. Laser cutting uses a high-powered laser beam to melt and vaporize material, resulting in precise cuts. Plasma cutting uses a plasma torch to melt and cut metal, while waterjet cutting uses a high-pressure stream of water mixed with abrasive particles to cut material.
bending
Bending is the process of forming sheet metal into a specific shape by applying force to the material. Manual bending involves bending the material using hand tools, while hydraulic bending uses hydraulic pressure to apply force to the material. Excellent nc plate bending machine is a computer controlled process that makes precise and accurate bending of materials. Sheet metal is machined into the desired shape using a series of rollers and blades.
forming
Forming involves reshaping sheet metal into a specific shape, such as rolling, stamping or spinning. Rolling involves passing a metal sheet through a set of rollers to form curved shapes, while stamping uses a punch to press the material into a specific shape. Rotation involves rotating the sheet metal around a mandrel while applying pressure to form a hollow shape.
The importance of CNC bending machine in sheet metal processing
High-efficiency nc plate bending machine has become an indispensable tool in sheet metal processing with its precision, efficiency and versatility. These machines use computer-controlled technology to precisely bend sheet metal into the desired shape. CNC press brakes offer several advantages over manual and hydraulic bending methods, including consistency, reduced setup time, less waste, and lower labor costs.
精度和准确度
CNC press brakes offer greater precision and accuracy than manual or hydraulic bending methods. These machines use computer-controlled technology to ensure that every bend is precise
efficiency
The high-quality nc press brake is efficient and can complete the bending work quickly and accurately. These machines can also process multiple parts simultaneously, reducing the time it takes to complete a project. This type of efficiency and productivity is critical in industries that require extensive sheet metal processing, such as the automotive and construction industries.
Flexibility and Versatility
The high-efficiency nc plate bending machine offers unrivaled flexibility and versatility in sheet metal processing. These machines can bend sheet metal into various shapes and sizes, making them ideal for a variety of industries. The press brake can also handle different types of sheet metal materials, including steel, aluminum, and copper, making it a versatile tool in sheet metal processing.
Cost-effective Although compared to manual or hydraulic bending methods, the initial cost of the bending machine
Might be higher, but they offer long-term cost savings. These machines reduce waste and increase productivity, resulting in lower labor and material costs. Additionally, the precision and accuracy of CNC press brakes reduces the need for rework or scrapping, further reducing costs.
Advantages over manual and hydraulic bending
consistency
Provides consistency in bending operations, ensuring each part is identical to the next. This consistency is critical in industries that require precise and consistent parts, such as aerospace and electronics.
Reduce setup time
High-efficiency nc plate bending machines require less setup time than manual or hydraulic bending methods. Computer control technology allows for quick and easy setup, reducing the time needed to prepare the machine for bending operations.
reduce waste
CNC press brakes produce less scrap than manual or hydraulic bending methods. The precision and accuracy of a CNC press brake ensures that every part is bent accurately, reducing the need for rework or scrap.
reduce labor costs
CNC press brakes require less labor than manual or hydraulic bending methods. These machines can process multiple parts simultaneously, reducing the need for manual labor. This reduction in labor costs can lead to significant cost savings over time.
Application in sheet metal processing
CNC bending machines have become an indispensable tool for several industries that require precise and accurate bending of sheet metal. For example, the automotive industry uses CNC press brakes to create complex metal structures for vehicle frames, suspension systems and exhaust systems. The aerospace industry also relies on bending machines to create complex metal parts for aircraft fuselages, wings and engines. The construction industry uses bending machines to make metal components for roofing, siding and gutters. Finally, the electronics industry uses highly efficient nc plate bending machines to manufacture metal parts for electronic housings, computer cases, and other electronic equipment.
钣金成型目前国内市场主要有冲压成型、折弯机成型、折弯机成型三种加工方式。数控折弯机可实现全自动或半自动生产。
但是，它们都有相当大的局限性。三种成型方法中的每一种都具有以下特点。
优点：
成型成本低，效率高，自动或半自动冲压比较容易实现；
缺点：
开模时间长，调模麻烦，模具成本高于其他加工方式，不适合中大型工件加工，批量加工更划算。
优点：
全自动或半自动效率高、劳动强度低；
缺点：
成型高度有限，折弯外径大于其他设备的加工半径，设备采购成本高。
西源机械认为，数控折弯机是钣金厂不可缺少的加工设备。压力传动轴可分为上折弯机和下折弯机。另外，按控制方式可分为普通折弯机、数字折弯机和数控折弯机。
优点：
打样效率高，适合加工大型材料，可实现钣金成型；
缺点：
很难做到完全自动化，自动折弯机械手的使用太有限，调试时间长。
对于锻压、冲压、钣金制造企业来说，数控折弯机数字化自动化的实现是必须要面对的重要课题。企业通过学习数字自动化，可以克服设计、制造、生产、管理等方面遇到的困难，最终改善制造条件，提高制造效率，降低消耗，节约成本，满足社会丰富多彩的物质文化需求。
