introduction
The singularity and special-purpose characteristics of the traditional steel drum production line have not adapted to the needs of the modern industrial main production mode. In order to meet the needs of multi-variety and multi-standard production in the steel drum industry, the flexible design of the steel drum main production line is established to realize the flexible design of the steel drum production knot, so that multiple varieties and multiple specifications can be produced in one production line. The purpose of the model steel drum. Enterprises can adjust the specifications and production of production according to their needs, improve their resilience, and achieve sustainable development and flexible changes.
1 Technical principle of steel drum flexible production line
1.1 Technical principles
In order to adapt to the changes of structural parameters such as material, material thickness, diameter, container height and opening form of steel drum, according to the established flexible design analysis model of steel drum production knot, several single machines (including barrel body) are included in the production line. Combined molding machine, folding machine, expansion rib forming machine, barrel cleaning machine, crimping machine, unloading machine, etc.) and transportation and loading and unloading mechanism (manipulator) set the necessary adjustment links, using PLC and single-chip control technology The function parameters such as working position, working size, working pressure, movement speed and cycle program of the power component are changed rapidly, quickly changed or quickly adjusted to realize flexible production of the steel drum production line.
1.2 Design ideas
The rapid realization of the main production line (within 4 hours) can be adjusted and flexible. When the production line has a flexible function, it is also easy to operate, practical and convenient. Specifically, the production equipment and the workpiece conveying mechanism (manipulator) on the flexible production line adopt axial and radial adjustable or interchangeable overall and component designs, and the parts related to the structure and the working size of the workpiece to be machined are provided with thread pairs. Adjustment mechanism, T-slot displacement adjustment mechanism, long groove displacement adjustment mechanism, hinge linkage mechanism, pin positioning or stop positioning interchange device, half-watt connection interchange device, split structure interchange device, exchange gear interchange device, etc. In the adjustment and replacement of parts, under the action of mechanical, hydraulic, pneumatic and other power systems, through the centralized control of the control system, the top parameters are quickly modulated.

2.1 Flexible design of crimping machine
According to the diameter, length and thickness of the product, the speed, pressure and position of the machine tool can be quickly adjusted to suit the main production of multi-variety steel drums. The bed has a four-column rail, a symmetrical seat plate and a welded base connection to form a frame-type support guiding system with good rigidity. In order to have "flexible" performance, the machine set the adjustment link: according to the requirements of GB 325 national standard 80 liters to 230 liters and 320 liters, the axial position of the sealing disk can be adjusted from 615 mm to 1050 mm; the radial direction of the winding wheel The position adjustment range is 415mm~700mm; the feeding speed of the crimping machine is stepless speed regulation in the range of 2.6mm/min~1060mm/min, and the rotation speed of the workpiece is designed to be 270r/min in the low speed section and 340r/min in the high speed section. According to the product conversion; the axial pressure of the sealing plate is designed to be infinitely adjusted between 280kgf and 3800kgf, and the curling feed force is infinitely adjusted between 630kgf and 7300kgf.
In order to achieve the above adjustment function, the spindle adopts mechanical two-speed transmission, and the feed and seal are hydraulically driven. The automatic control system adjusts the parameters such as the working pressure, movement speed, material plastic deformation and holding time of the hydraulic system of the machine according to the material thickness and material of the new variety. The flexible production function is realized by the interchangeability of the sealing disk, the curling wheel and the like. While realizing the flexibility of the machine tool, it is also considered to be simple and convenient to operate.

2.2 Flexible design of the barrel joint forming machine
The machine tool automatically completes the three steps of the barrel folding, corrugation and ring ribs on one piece of equipment. In order to realize the flexible function, the machine tool design has a uniform replacement of the forming tools of different specifications. The parameters such as the extrusion stroke of the machine tool, the workpiece clamping centering diameter, the pressing force and the extrusion speed can be adjusted steplessly. The overall layout of the frame of the four-column guide column is used to improve the rigidity of the machine support guiding system. The forming tool adopts the rolling wedge iron expansion mechanism and the extrusion hemming die design, so that the plurality of corrugations of the barrel body are sequentially and non-interference continuous expansion pressure. Forming tools for a wide range of barrels use a uniform tool core that does not require replacement. The whole power of the machine adopts hydraulic transmission, superimposed valve and DC wet electromagnetic reversing valve to form a centralized control system for anti-interference of multi-power components. The variable-power constant-power control system design and automatic timing full-load unloading of the quantitative pump are used to reduce the system. heat.
Conclusion
The flexible production technology of steel drums is the main means for the current steel drum packaging industry to adapt to market dynamics and to continuously update products. Practice has proved that the application of flexible automated production systems can increase productivity by a factor of 1 to 4, and the trial cycle and cost of new products can be reduced by 1/3 to 1/2. Thereby, the manufacturing cycle and delivery time can be shortened, the product replacement can be accelerated, the cost can be greatly reduced, the enterprise's ability to adapt to market changes and the competitiveness can be improved, and the enterprise can bring obvious economic benefits. Flexible steel drum production line from 2005 onwards has been successfully applied in Guangdong, Fujian, Jiangsu, Shaanxi, Sichuan and other places. Since it was put into production, the operation has been stable, reliable, and the economic benefits brought by flexible production have been remarkable. 2013 and Yangzhou in Jiangsu Province to build in a flexible, low-level radioactive nuclear waste storage and transportation containers automated production line, which uses a flexible production technology, to meet the specifications of nuclear waste containers and more automation of our production requirements, to achieve a nuclear waste container Industrialization of manufacturing, making nuclear waste container manufacturing standards reach advanced industry level; quality and product performance are leading domestically; promoting the application of nuclear waste containers in nuclear power plants, and reducing recycling waste through the application of nuclear waste containers, thereby protecting the environment, conducive to the development and application of nuclear energy, economic and social benefits significantly.
Practice has proved that: steel drums flexible production technology with good promotional value; the use of innovative design concept worthy peer reference.
