1. مشكلة الإصابة الميكانيكية

تشير الإصابة الميكانيكية إلى حادث ميكانيكي يحدث عندما يتم إطلاق طاقة ميكانيكية عن طريق الخطأ. هناك العديد من مصادر الخطر ، وهي أيضًا أكثر الإصابات تعرضًا لمشغلي الانحناء أثناء عملية الإنتاج. المخاطر الرئيسية للإصابة الميكانيكية هي كما يلي:

• يجب ألا يمد مشغل آلة الثني جزءًا معينًا من جسمه بين القوالب العلوية والسفلية تحت أي ظرف من الظروف ، مثل عندما يمد يده بين القوالب العلوية والسفلية لضبط الوضع. لأنه عندما يمد المشغل يده بين القوالب العلوية والسفلية ، قد يصطدم القالب العلوي أو الموضع الخلفي لماكينة الثني بأيديهم ، مما يشكل تهديدًا للسلامة الشخصية.

• Due to the wide variety of parts for bending operations, when the processing size of the parts is large or heavy, two people need to cooperate to complete the bending operation of the product. At the same time, two operators are required to simultaneously push the product to the designated position. When pushing the parts, two people must complete it at the same time. There are great requirements for the cooperation ability of the operators between people and people and machines. The probability of accidents increases, and the parts are very likely to collide with their heads during the process of falling. Threat to life safety. Analysis of Bending Process

• عندما تكون آلة الثني قيد الاستخدام ، يتم استخدام مفتاح التحكم بالقدم لدفع الأجزاء يدويًا ، و القوالب العلوية والسفلية are moved under the action of hydraulic pressure, so as to achieve the requirements for the bending of the parts. When bending small parts or the size of the parts is smaller than the upper die of the bending machine, due to the incorrect bending gesture, the operator’s hand will be clamped between the upper die and the part inadvertently.

Because the sheet metal process itself is a relatively complex metal processing process; Shenzhen sheet metal processing manufacturers remind you that it is easy to operate by unskilled personnel There are many problems, so if you need more than one person to operate, you should pay attention to the safety of the operators, and then inform them of some problems that need to be paid attention to prevent some confusion and troubles due to unskilledness. Analysis of Bending Process

The bending process is a manufacturing operation used to deform or reshape materials, typically metal sheets or tubes, into specific shapes or angles. This process is commonly used in various industries, including aerospace, automotive, construction, and metal fabrication. Analyzing the bending process involves understanding its key components, methods, equipment, and important considerations. Analysis of Bending Process

Key Components of the Bending Process:

Material Selection: The choice of material plays a critical role in the bending process. Different materials, such as steel, aluminum, or copper, have varying properties and require specific bending techniques and equipment. Analysis of Bending Process

Bending Methods:
a. Press Brake Bending: This is one of the most common methods, where a press brake machine exerts force on the workpiece, causing it to bend around a die or tool.
b. Roll Bending: In roll bending, a set of rolls is used to gradually bend a workpiece into a curve or a circular shape.
c. Tube Bending: Specialized equipment is used to bend tubes or pipes into various angles or shapes, commonly used in plumbing and HVAC systems.

Tooling and Dies: Specific tooling and dies are required for each bending operation. The selection of the die’s shape and size determines the final bent shape.

Equipment: Machines like press brakes, roll benders, or tube bending machines are used to apply force and reshape the material. Analysis of Bending Process

Material Properties: Understanding the material’s mechanical properties, such as yield strength, tensile strength, and elasticity, is crucial in predicting how it will behave during the bending process.

Bend Radius and Angle: The desired bend radius and angle must be precisely defined, as they dictate the tooling and setup required. Analysis of Bending Process

Analysis of the Bending Process: Analysis of Bending Process

Springback: When a material is bent, it tends to partially return to its original shape due to its elastic properties. Calculating and compensating for springback is essential to achieve the desired final shape accurately.

Material Thickness: The thickness of the material affects the bending process, as thicker materials may require higher forces and specialized equipment.

Stress and Strain: Analyzing stress and strain in the material helps ensure that it doesn’t exceed its elastic limits, which could lead to cracks or permanent deformations.

Tool Wear: Over time, tooling and dies can wear out, affecting the quality of the bends. Regular maintenance and replacement are necessary to maintain precision. Analysis of Bending Process

Tolerance and Quality Control: Maintaining tight tolerances and conducting quality checks throughout the bending process are essential to ensure the final product meets specifications.

Material Fracture: Excessive bending force or incorrect tooling can lead to material fracture or cracks. Analyzing and minimizing the risk of fracture is critical.

Cost Analysis: Assessing the cost-effectiveness of the bending process, including equipment, labor, and material costs, is crucial in manufacturing decisions.

Environmental Impact: Understanding the environmental impact of the bending process, including energy consumption and waste generation, is becoming increasingly important in modern manufacturing.

In summary, the analysis of the bending process involves a comprehensive understanding of material properties, equipment selection, tooling, quality control, and cost considerations. Proper analysis and optimization of these factors are essential for producing high-quality bent components while minimizing waste and cost.
