The power tool accessory industry seeks a breakthrough in the development process

Tracing back to history, the tools that humans first used were made of stone, and later they gradually used metal as a material. This is the innovative progress of tools in materials. From the point of view of the power source of the tool, it was a manual tool in the beginning, and later there were power tools, and most of the tools can be replaced by machines. The innovation process of modern tools can be summarized as: from manual tools to AC tools, and then to DC tools, and DC tools can be divided into nickel-cadmium, nickel-zinc battery tools, and lithium battery tools.

hardware tools

The innovative development of the tool is based on the principles of convenience, efficiency and environmental protection. Although the early AC power tools were powerful, they had to have long enough power cords for outdoor use, which was very inconvenient. Later, gasoline-powered tools were also developed, but they were expensive, heavy, noisy, not environmentally friendly, and difficult to launch in winter. Lead acid batteries and nickel-cadmium nickel-zinc batteries have also been phased out due to their own weight or insufficient power. But today's lithium battery tools have solved the above problems. Such batteries are lightweight and durable and have been widely used in various fields.

Wu Guimin, a design expert in the hardware industry, believes that innovation must first solve problems in real life. For example, when knocking nails, many people have experienced being hit by the hammer in the right hand to the left, but now with the nail hammer, it will never happen again. A 6-inch nail is as long as It can be driven into the wood in seven or eight seconds. The price of this tool in the United States is 70 dollars. Although it is much more expensive than an ordinary hammer, it can solve the task of nailing in a narrow space. , Such as nails under the table or in the drawer, only use such tools.

If there are new and outstanding products launched in the industry, as an innovative company, it is necessary to seize the time to learn and do its own innovation. Everyone knows that in the power tool industry, Bosch, Mai Taibao, Stanley Black & Decker are recognized as leading enterprises in the industry, and other companies should learn from them with an open mind.

There used to be a lithium battery multi-function shovel that created a miracle in the industry. At first this was the first new product launched by a foreign company, but a company from Yongkang made improvements on the original. In the end, this product was made for this company within three years. The factory has earned 80 million yuan. It can be said that a product saves a factory. In fact, there are only a few products that really make money in a factory. So pay close attention to the pace of industry leaders and think about what you can do in this trend. What, do not blindly follow others, but look for entry points based on their own technical and human resources advantages.

Wu Guimin pointed out in the report that the majority of enterprises must understand that lithium electric tools are the development trend of the industry, and all manufacturers of tool manufacturing must think about which hand tools can be transformed into electric tools.

An idea brings a whole new industry

As we all know, the functional innovation of power tools is difficult, and this innovation is the most fundamental innovation. For example, the functional innovation of bench drills has always been the direction pursued by Qingdao Diendi Group. In the past, when using electric bench drills to drill holes, the "trial cutting method" that has been used for hundreds of years since the invention of bench drills is still used: without turning on the machine, dropping the drill down and repeating the experiment to see if you can reach the point to be drilled Experiments are usually performed four or five times. This old functional method is time-consuming and inaccurate, but some engineers have suggested using a laser rangefinder to locate it.

At first, many people heard that the first reaction to this idea was impossible! Because the only way to achieve laser positioning is to install a laser facility in the middle of the drill bit. How is this possible? But the chairman of Qingdao Diendi Group firmly believes that lasers can be positioned. It is required to overcome this difficulty no matter how long. Therefore, they embarked on the road of research and development without hesitation.

As a result, a research and development team was quickly established in Diendi. After nearly two and a half years of painstaking research, we found a solution: using two laser generators that can emit laser surfaces to combine one laser spot to achieve accurate positioning. However, problems followed. The laser positioning system manufactured in this way cost nearly 1,000 yuan, which is higher than the most expensive bench drill, which is obviously impossible to be accepted by the market. After working hard for a long time, in the case of ensuring the accuracy and the effect is not bad, the cost of the laser positioner has finally dropped significantly from nearly 1,000 yuan.

At present, the annual output of various bench drills around the world is about 2.6 million units. At the same time, a large part of medical equipment also needs to install such laser positioners. Roughly, there is a market capacity of 5 million pieces per year. This is an annual New industries with more than 1 billion yuan in demand. The next step is for this company to focus on this industry.

There is a large gap between China's power tool technology and the world's leading level

In general, there is still a large gap between the technical level of China's power tools and the manufacturing power, mainly due to the monotonous product appearance, unstable quality, high-frequency screams, low unit weight output, and electromagnetic compatibility that does not meet the requirements. Wait. For example, in terms of output per unit weight, domestic electric drills are currently about 30 to 50 watts / kg lower than well-known foreign brands; impact electric drills are about 30 to 80 watts / kg lower.

At present, users have higher and higher requirements for the quality of power tools, especially paying attention to indicators such as product efficiency, weight, and life. For example, in the construction industry, the quality problems exposed by domestic electric tools mainly include: the electric hammer is easy to heat, the continuous working time is short, the electric hammer has a small impact force, and the vibration is large. The operator must press hard to deepen; the drill is easy to wear and easy to break, etc. .

At the same time, most of the domestic power tools do not meet environmental protection requirements. According to regulations, power tools should meet the requirements of the new radio interference standard (commonly known as EMC). To improve the technical level of EMC, new materials and technologies must be used to reduce product noise, such as the use of rare earth permanent magnet materials. Permanent magnet power tools can improve efficiency, reduce noise, have no radio interference, and improve product performance. At present, China is still in the trial production stage in terms of permanent magnet power tools. In addition, only a few varieties of domestic electric tools, such as impact electric drills, electric drills, and electric hammers, have electronic speed regulation functions, and most of them are single-speed products that cannot meet user requirements .

Low insulation level is also the bottleneck that domestic electric tools need to break through. At present, the insulation structure of domestic electric tools is Class E, and foreign brands have reached Class B. At present, domestic companies have just started the research on Class B series insulation motor insulation materials. Research on ergonomics, electronics, large-capacity rechargeable batteries, fast chargers, insulation structures, transmission structures, and design designs has been carried out earlier abroad, and has been widely used in power tools. Little research.

For a long time, most power tool companies in China have survived on cheap labor. Now, in the face of the sharp rise in raw material and labor costs, there is only a way out for change.
