Lecture of steel Drum Production Line Training - TWO

Section Two: Brief introduction of Steel Drum Production Equipment

Our poor foundation cooper production equipment. Liberated, the old China left us alone but only a few old mess. After the liberation, after the majority of workers, technicians and cooperage work together to gradually transform the old obsolete equipment, and vigorously technological innovation, the single gradually link up to form a semi-automated cooperage lines. , And especially since the reform and opening up, we have the introduction of foreign cooperage new equipment, new technology digestion and absorption of foreign cooper, cooper increasing degree of automation equipment, the cooperage production and on a higher level. Cooperage produced using the coil, the cooperage equipment has added a new partner - uncoiler and leveler. At present, China's cooperage equipment has been completely transformed, and a new automated cooperage strip production lines across the country take root and flourish in the results for the country's economic development has provided a large number of steel drums with the quality to meet all walks of life needs.

First, the transformation of the situation cooperage equipment

Cooperage transformation of equipment generally go through three processes: the transformation of one single edge; Second is to increase the degree of automation equipment transformation; three volume analysis is the use of post-production equipment modification.

 

1, single edge transformation

Cooperage single production is a very backward mode of production. Every process, all posts are independent of each other, there is no contact. Semi-finished products are produced by human handling, labor intensity greatly, labor productivity is very low. And because both rely on each processing link between human handling, so be repeated positioning, but also seriously affect product quality. Liberation, the vast majority of the cooperage companies have been using this old legacy of the old society, cooperage backward mode of production.

This backward mode of production must be changed! Majority cooperage workers and technical staff, teamwork, hard fight. First, every process, linking several stand-alone, and then a few processes are also connected into the line, and finally completed the entire basic cooperage lines. This semi-automated production lines Barrel successful transformation can be said that a revolution in the history of our country cooperage, it not only multiplied exponentially increase labor productivity, greatly reducing the labor intensity, but also the quality of the drums the great strides to improve.

2, improve the transformation degree of automation equipment

Equipment modification is endless. Cooperage workers are not satisfied with what has been achieved, they further transformation equipment connected devices and linked institutions in order to improve the degree of automation equipment, and using a variety of automatic control mode, the automatic control is more reliable and more flexible.Cooperage used in the production of automatic control mode is up to the relay control.With the composition by the number of relays required for control logic circuit, the direct use of strong power to complete the automatic control. However, bulky relay control circuit, circuit complexity, poor reliability, and high tempo of the automatic control can not be completed. Therefore, later replaced by programmable logic controller, and some of the more advanced devices are generally used cooper programmable controller.Programmable logic controller with a simple instruction to edit sixteen, by one input to the controller of the storage section, the processing by the CPU, input control signal to drive electrical components required to complete the automatic control. It controls high tempo, control is easy to change, just modify the program to achieve their goals. Microprocessor will be more advanced automatic control headquarters, such as it is both sensitive and accurate control of the temperature of the drying chamber, now it has been in the march to a higher goal.

As China's economy continues to develop, cooperage equipment modification is also bathed in the great spring. The introduction of foreign advanced equipment, digestion and absorption of foreign advanced technology, has become a device to improve the degree of automation of cooper and an effective way.

3, the use of volume analysis of post-production equipment modification

Barrel length steel plate coil replacement tablet has many advantages, for example, can reduce scrap to save raw materials, can be continuously processed to reduce the processing chain, thereby improving product quality. Moreover, compared with the flat coil, the price is cheaper, but also more convenient transportation. Therefore, the current alternative to flat coil cooperage production has become an inevitable choice.

Of course, the coil used in cooperage production has also brought a series of problems, such as flat rolled coil must be used only after continuous crop production but also on positioning proposed new topics. So, whether it is top-bottom barrel production, not the barrel body production, must reinvent the original equipment.

In the majority of technical staff and the joint efforts of coopers, the first successful development of the barrel top bottom coil, flat dual automatic stamping lines, and then successfully developed an automatic barrel body coil cutting line. Which is suitable for the production of open-Zheng Barrel machines and leveling machine for the first time joined the ranks of cooperage equipment. With the actual production needs, decoiler and straightening machine and be constantly improved and perfected. In addition, the coil of continuous production, while promoting awareness of the feeding mechanism and the positioning device to conduct a comprehensive transformation, so that quantitative feeding place, positioning accuracy, greatly improving the quality of products.

With the rapid development of manufacturing cooperage, cooper equipment needed to keep upgrading. Such as the use of curling round it must be equipped with pre-roll equipment, automatic seam welder uses it must be equipped with a faster tempo feeding conveyor equipment, new coating technology adoption must also be equipped with suitable spray equipment ...... conveyor. In short, equipment modification is endless, in order to produce high-yield steel drums, we must constantly strive to keep making progress, constantly replaced with a new advanced equipment obsolete outdated equipment, toward a higher goal.

Second, an overview of the main equipment Barrel

Cooperage equipment including cutting grinding equipment, welding equipment, barrel body shaping equipment, curling equipment, coating equipment, stamping equipment, closure forming equipment and testing equipment. Cooper in many devices, welding device and the crimping device is the most important, and the welding equipment in the seam welding and crimping machine crimping devices is the most critical cooper device.

1, seam welding

Seam welding machine is used to weld seam straight barrel body, barrel body straight seam leaks, good or bad quality by seam welder decision. Thus they will know seam welder in cooperage production in an important position. Using resistance welding seam welding, resistance welding is the use of heat, so that local melting weldment or reach a plastic state, under pressure to form a strong joint side continued soldering method.

Currently cooperage produced using the seam welder can generally be divided into two categories: one is hand-feeding semiautomatic welding seam; Second, automatic seam welder.

Semi-automatic seam welding machine, barrel body panels must first rolling machine rolling barrel body is formed, and then on the spot welder spot welding lap locate pre-assembled, and then complete semi-automatic seam welder seam welding. The feed barrel body, the reduction by the electrode wheel manual control.

Automatic seam welding machine, barrel body panels into the automatic seam welder, the first volume Yuan Cheng barrel body by promoting institutional constraints of the guide positioning mechanism under the wheels into the seam welding electrodes, followed by complete seam welding electrode wheel. The entire welding process automatically, without manual operation.

2, crimping machine

Crimping machine is used to seal steel drum roll bottom, it will barrel top and bottom barrel body roll together. Top bottom circumference barrel leaks, securely connected both directly related. It can be seen curling in cooperage production in an important position. Crimping machine with rotary spinning, sandwiched between the barrel body rotates on tires with rims, curling down from the rolling wheel, complete curling. By the crimping rollers rolling curve decided to form a double flat curling, curling round the double and triple circle curling.

The majority of our horizontal crimping machine, its activities and the movement of the wheel arch and down movement can be mechanical cam and rocker mechanism, pneumatic transmission and hydraulic transmission to achieve. Crimping machines generally have coordinated their processing beats transport mechanism, the volume OIC Sealing glue gluing institutions and under the control of the automatic control device to complete the drums of curling.

Cooperage equipment involves a broader, each device are closely related with the quality of steel drums. Such as the impact surface quality steel drum coating equipment, stamping equipment most widely used to determine the quality of the barrel body scissors grinding equipment and barrel body shaping equipment and affect the quality of closure closure forming equipment.
