Win-door Machienry Development At Present
Mar 30, 2018

With the launch of German Industry 4.0 and the advent of China’s Internet+ era, a new industrial revolution has come to us. Each company in the future is a "data-driven enterprise." Real-time, sophisticated, and intelligent manufacturing methods require the integration of the current production system, and MES, ERP, and PDM must implement overall production control. As a door and window curtain wall equipment manufacturing enterprise, it is not enough to simply serve the automation and intelligence of the equipment to serve the global door and window curtain wall system. The digitalization of door, window, and curtain wall production companies requires the integration of data, equipment, status, quality management, on-time delivery of materials, production statistics, timely delivery of products, and on-site data collection. The “+” era of the Internet has brought unprecedented opportunities and challenges to the production of door and window walls and equipment manufacturers. With the changes in the history of mankind, the production process of doors and windows and the level of equipment are constantly evolving. Intelligentization and digitization have become the development trend of the curtain wall equipment in the future.

    From the beginning of human settlement, there is the concept of doors and windows. However, with the leap-forward development of society, doors and windows have undergone tremendous changes. The breakdown of every door and window, the fall of old products, and the upgrading of new products all symbolize the continuous improvement of rich production of door and window production equipment, which adds more expressions to the humanistic qualities of architecture style. Every development and new equipment has a qualitative impact on people's lives.

One, early stage of the wooden window

   (1) Front window: Combination of wood frame and paper

   (2) Late Stage Window: Combination of Frame and Glass

Early forms of doors and windows were varied and varied. The exquisite and gorgeous doors and windows of the palaces and altars, the elegant and elegant doors and windows of the literary landscape architecture, and the lively and lively architecture of the doors and windows of the native buildings make the original and practical doors and windows the focus of architectural decoration. At the time, the objects used to make doors and windows were simply not called "equipment" and could only be called "tools." At that time, the production tools of the doors and windows were mainly woodworking tools, scrapers, chisels (the surface of the wood was cut by a hammer to cut and cut, etc.), saws (used to cut large wood), ink fountains (used to draw long lines), and pull diamonds. (drill holes in the surface of wood), camel drills (drilling holes in the surface of wood), rulers (calculation, measurement of the size of wood), rakes (cut down, inwards, play the role of logging), hands Saw (cut small wood, saw blade is often curved, more flexible), flat tuner (planing the wood to flat, straight, smooth degree), ink pen (cut bamboo flat, cut into a knot, used to Draw lines on wood) etc.

 Second, the era represented by steel windows

    In 1911, fasting steel doors and windows from the United Kingdom, Belgium, and Japan were introduced into China, and were mainly concentrated in Shanghai, Guangzhou, Tianjin, Dalian and other coastal port cities as "rental places." In 1925, China's national industry in Shanghai started to produce small quantities of steel doors and windows. Until the founding of New China, there were only 20 small workshops for handicrafts. After the founding of New China, steel doors and windows enterprises in Shanghai, Beijing, Xi'an, and other places built large production bases for steel doors and windows, which have been widely cited in industrial buildings and some civil projects. In the late 1970s, the country vigorously implemented the resource allocation policy of “using steel to replace wood”, and promoted the climax of the promotion of steel doors and windows, steel feet, and steel formwork (abbreviated as “three steels and new generations of wood”) throughout the country, greatly advancing steel doors and windows for fasting. development of. The 1980s were the heyday of traditional steel doors and windows. The market share once reached 7% in 1989 (70%).

    The main link of the fasting steel window in the production process is "welding process", and the equipment mainly used is resistance welding machine or flash butt welding machine.

    Although the performance of the steel window is strong and durable, but due to few domestic manufacturers of high-quality cold-rolled sheet, it is difficult to scale large-scale production. The long non-standard production cycle coupled with high prices, corrosion, technology and technology is not room for change. As a result, competition with aluminum alloy doors and windows in the future quickly turned out to be ineffective. "Poor changes, changes changes," and traditional steel windows are also seeking opportunities for change and new life in the market. In the mid-1980s, Italy introduced color steel doors and windows to bring the cases and templates for the transformation and upgrading of traditional steel windows. In the early 1990s, domestic companies successively introduced a number of color steel doors and windows production lines from Italy. Color steel doors and windows production process for the use of 45-degree milling - press punching - 90 degree pneumatic foot - riveting forming - packaging is completed, including the main equipment cutting machine and cold bending machine. Energy-saving and emission-reduction is a common topic in the world, and it is also an inevitable trend in the development of Caigang's door and window equipment.

 Third, the era of aluminum alloy-based

    At the beginning of the 1970s, aluminum alloy doors and windows were introduced into China. However, in foreign embassies in China and a few foreign-related projects, in 1978, Beijing, Guangzhou, Xi'an, Shenzhen, etc. Began to use small batches in engineering construction. In the 1980s, all parts of our country began to introduce complete sets of production equipment and technology such as foreign construction aluminum profiles, aluminum doors and windows, automatic doors, aluminum alloy glass doors and windows curtain walls, new heat-reflective coated glass, safety glass, and product accessories. According to statistics, in 1989, there were more than 390 production lines for aluminum profiles in the country, and the combined production capacity reached 220,000 tons. The aluminum alloy doors and windows complete sets of equipment in this country are still very immature and are in a stage of introduction and learning.

    Compared with fasting steel windows, aluminum windows are highly malleable and can be processed in many ways, and are less prone to rust. In addition, they have low noise, no ground rails, and are easy to clean and sanitary. They are not deformed, they are not easy to damage, and they are space-saving. Bright and spacious. However, the aluminum alloy conducts heat quickly and the sealing effect is not very good. The energy consumption is too high and does not meet the energy saving requirements. The equipment at this time is usually a simple single-head saw and a small punch.

Fourth, ordinary steel doors and windows as the representative of the era

    In order to solve the problem of insulation of doors and windows, China began to import plastic steel doors and windows from Germany in 1983. Plastic-steel doors and windows began in the late 1950s and were first developed by Germany, a hard, low-foam building plastic called UPVC that can be used in construction. The technology at the time was not very advanced and both used single-cavity or two-cavity structures. In 1991, a large number of domestic manufacturers such as equipment, molds, profiles, and assembly equipment emerged. In 1996, the state strongly promoted the production of plastic steel doors and windows, thus ushering in the prosperity of the plastic steel doors and windows industry. Plastic steel doors and windows have a good thermal insulation performance, its heat transfer performance is very small, heat insulation effect is remarkable, especially for wood with its air conditioning equipment, modern buildings are more applicable.

    At present, China's plastic steel door and window assembly equipment has sawing, milling, welding, clear corner, processing center automatic line, other types and car platform a total of seven categories, about more than 100 varieties of different performance, different specifications And meet the needs of different production processes equipment. Among the most basic equipment are profile cutters, welders, sinks, V-saws, bead saws, mid-saws and clearing machines. After more than ten years of introduction, digestion, absorption, and development of foreign technology, plastic-steel window equipment has become a professional equipment system with a complete system, large-scale technology, and a level of automation close to that of foreign counterparts.
