When was the beveling machine invented?

Bevelling machine is an important tool widely used in the welding industry, its invention and development reflect the progress of welding technology, but also reflects the needs of industrial production changes. This paper will discuss the invention background, technical evolution, application field and future development trend of beveling machine in detail.

1. Background of invention of beveling machine

The emergence of beveling machine is closely related to the development of welding process. Welding as a process of joining metal materials, its history can be traced back to ancient times. As early as 4000 BC, the ancient Egyptians had mastered the basic technology of metal welding. However, with the arrival of industry, metal processing technology has gradually developed to chemical and high efficiency, and higher requirements have been put forward for welding technology.

At the beginning of the 20th century, with the rise of heavy industry, especially the construction of large structures such as ships, Bridges and pressure vessels, higher standards were put forward for the quality and strength of welded joints. In the traditional welding process, the shape of the welded joint often directly affects the quality of the welding. In order to ensure the strength and tightness of the welded joint, the metal edge needs to be beveled before welding. Groove treatment can increase the contact area of the weld and improve the melting effect in the welding process.

Two, the invention and development of beveling machine

The invention of beveling machine can be traced back to the 1930s. At that time, with the continuous development of welding technology, the traditional groove treatment method is becoming less and less efficient. Manual bevelling is time-consuming and laborious, and it is difficult to ensure uniform and accurate bevelling. This problem led to the invention of the beveling machine.

The earliest bevelling machine was jointly developed by some mechanical engineers and welding, who wanted to solve the inconvenience of manual bevelling by mechanical means. The early beveling machine is mostly a simple mechanical device, which mainly relies on the cutting action of the tool to complete the processing of the beveling. With the progress of technology, the structure and function of the beveling machine are constantly improved, and it has gradually evolved into a modern electric beveling machine and automatic beveling machine.

Three, the technological evolution of the beveling machine

#### 1. Manual beveling machine

The initial beveling machine is mostly manual operation, and the user needs to manually adjust the Angle of the beveling according to the requirements of the workpiece. Although the cost of this type of beveling machine is relatively low, the processing efficiency and accuracy are limited. On this basis, engineers began to explore more efficient bevelling machinery.

#### 2. Electric beveling machine

With the development of power technology, electric bevelling machines began to enter the market in the 1960s. The appearance of electric beveling machine has significantly improved the efficiency and accuracy of beveling processing. This type of machine is usually equipped with a high speed motor, which can quickly and accurately complete the bevel machining, while reducing the error of manual operation.

#### 3. Automatic beveling machine

After entering the 21st century, the rapid development of automation technology provides a new possibility for the evolution of beveling machine. Modern automatic beveling machine can complete the beveling processing, but also through the CNC system to achieve automatic operation, greatly improve the production efficiency and processing accuracy. The automatic beveling machine can automatically adjust the Angle of the tool according to the preset parameters to adapt to the beveling requirements of different types of workpieces.

Four, the application field of beveling machine

The application field of beveling machine is very wide, mainly including the following aspects:

#### 1. Shipbuilding

In shipbuilding, welding is one of the key processes. The use of beveling machine can effectively improve the quality of hull welding and ensure the strength and stability of ship structure. By bevelling, the welded joint can be tighter, avoiding stress concentration and damage during the ship's voyage.

#### 2. Construction works

In large construction projects, bevelling machine is widely used in steel structure welding. Especially in the construction of high-rise buildings and Bridges, the application of bevelling machine can improve the bearing capacity of welded joints and ensure the stability of buildings.

#### 3. Petrochemical Industry

In the petrochemical industry, the welding quality of equipment is directly related to the stability and efficiency of production. The use of beveling machines can ensure that the welded joints of pipelines and containers meet the high standard of sealing requirements and avoid leakage and accidents.

#### 4. Shipbuilding and heavy machinery

Beveling machines also play an important role in the manufacture of shipbuilding and heavy machinery. The traditional way of beveling large-size workpiece is difficult to ensure accuracy, and the use of beveling machine can effectively solve this problem and ensure the processing quality.

Five, the future development trend of beveling machine

With the continuous progress of science and technology, the future development trend of beveling machine is mainly reflected in the following aspects:

#### 1. Automation

Future bevelling machines will be more and more automated and optimized using manual automation and big data technology. The automatic bevelling machine can automatically adjust the bevelling parameters according to the material type, thickness and welding requirements to achieve better processing results.

### 2. High efficiency

In industrial production, the pursuit of efficiency has always been a theme. The future beveling machine will continue to develop in the direction of high speed and efficiency, shorten processing time and improve production efficiency.

#### 3. Health and energy conservation

With the increase of health awareness, the future beveling machine will pay more attention to health and energy saving in design and use. The application of new materials and technologies will reduce energy consumption and waste emissions, in line with the requirements of sustainable development.

#### 4. Multi-functional

Modern industry puts forward higher requirements for the comprehensive performance of equipment. The future beveling machine will develop in the direction of multi-function, which can be beveling treatment, cutting, welding and other processes, and improve the application value of the equipment.

6. Conclusion

The invention and development of beveling machine is an important sign of the progress of welding technology, and its application greatly improves the quality and efficiency of welded joints. With the continuous progress of science and technology, the application of beveling machine in various fields will be more extensive, and the trend of automation, high efficiency, hygiene and multi-function will continue to promote the development of industry.

In the future industrial production, beveling machine will play an increasingly important role to help all walks of life to meet the growing production needs. Through continuous innovation and development, the beveling machine will bring greater changes to the welding industry and promote the entire manufacturing industry to a higher level.
