A new type of aluminum anti-theft cover high cover group die secondary high speed punch developed successfully

At present, the international and domestic production of aluminum anti-theft cover equipment, mainly the traditional single-head punch and group punch punch, production specifications vary, according to the height of the cover is divided into a stretch, secondary stretch, stretch three times One of the stretches, commonly known as low cover, is now international and domestic single-head punch and group punch, the maximum tensile height of about 24mm, more than this height, commonly known as high cover, you must use two or three stretch.

In recent years, the output of white spirits in China is about 8 million tons, with about 16 billion caps per year, of which the height is 35mm, and the size of 29.7mm in diameter is about 20-30%, about 3.2-4.8 billion per year. The bottle cap must be stretched twice, and can only be produced with a single head punch. The efficiency is very low. The output of a single head punch is about 2,500 heads per hour, and the secondary stretch is about 5,000 heads per hour. The labor cost is high. , The energy consumption is large, and the workshops occupy a large area. Under the current situation where the profits of the industry are minimal, it has brought great difficulties to the survival and development of the enterprise. How to reduce the production cost and increase the production efficiency is the survival and development of each enterprise. The fundamental way out, where is the road? Leaders and engineers and technicians of the Gaizhou Liaonan Bottle Cap Factory are thinking hard.... After in-depth investigation, careful analysis and scientific demonstration, the company decided to: make full use of the experience of producing punch punch for many years; break down technical problems with innovative ideas; organize leadership, engineering and technical personnel, and technical workers to tackle problems; break the current domestic and international Unresolved bottleneck of high-35mm aluminum anti-theft cap once stretched, we must dare to be the world first, win glory for the lid manufacturing industry, win glory for the metal packaging industry, and add luster to metal packaging machinery.

Technological innovation not only requires extraordinary courage, but also requires scientific rigorous attitude, rich theory and practice, and meticulous work style. Gaizhou City Liaonan Bottle Cap Factory technical research personnel to the factory in 1996 developed and produced 15 die crown cap punch, 2003 developed the tea wax aluminum box 9 die punch, developed in 2004 the 10-die aluminum anti-theft cover punch The performance, characteristics, advantages and disadvantages were thoroughly analyzed. Firstly, the design concept of the high-speed press model was formulated: it should be composed of an automatic feeding system, a continuous stamping and braking system, a unique product output device, and a collection of excess material. The installation system, automatic lubrication system, fault display and alarm system are composed of a set of advanced microcomputer control and reserve interfaces with other processes. Secondly, a set of 35mm high-cap single-stretch single-mode stamping tensile tests should be designed and manufactured first. After obtaining a series of data and experience on the material, processing technology, stamping effect, etc. of the mold, the number of group molds and the combination method are determined. After repeated trials, the high-35mm aluminum anti-theft cap single-mode stretch has been successful! This invisibility has added great confidence and courage to everyone, and is only one step away from the group model. However, they are fully aware that the next step is a more difficult step and the most critical step. Based on the specifications, materials, punching performance, and the most economical layout of common aluminum sheets, they repeatedly discussed, discussed, and revised them, and finally developed a trial scheme for the "11mm high-speed punch press for 35mm high-profile aluminum anti-theft caps." . During the implementation of the project, engineers and technicians are meticulous in designing drawings, and the workers' masters produce parts, assembly, and debugging are more perfect. After months of hardships, in October 2008, China's first "35mm high-aluminum anti-theft cover group model two continuous high-speed punch" was finally born! After the user's trial, it reflects well.

The punching production line covers an area of ​​7.5m2, the production efficiency is 53,000 pieces/hour, and the power consumption of the entire equipment is only 9.6KW/h. The operating system adopts the international advanced touchscreen computer control system, which is simple, easy to understand, and only works normally. Need 1-2 people. Its success symbolizes that China's aluminum security cover high-cover production equipment has made a qualitative leap in the first-stretch group-type secondary continuous punching machine and reached the international advanced level. (The author understands that at present, there is no international stretch to reach 35mm. Height aluminum cover). The advantages of the equipment are international quality, domestic cost, simple operation and convenient maintenance. Each production of 10,000 bottle caps can save about 36 yuan in working hours, energy consumption, labor, etc., which is a large-scale production of aluminum. Quality anti-theft cover of advanced equipment.
