What impact will the reconstruction of old buildings and the installation of elevators have on laser cutting machine manufacturers?
60% of elevator car parts are sheet metal. The optical fiber laser cutting machine produced by Longtai Laser is a sharp tool for professional sheet metal processing.
According to the survey, the average weight of each elevator car must be 810kg stainless steel plates. The elevator parts include mechanical equipment parts, sheet metal, electrical equipment parts and standard parts. Among them, 60% of elevator car parts are sheet metal, involving nearly 1000 kinds in total. According to the plate thickness division of common raw materials, it can be divided into thin metal plates (0.2-0.8mm), medium thick plates (1-1.5mm), medium thick plates (2-3mm) and thick steel plates (4.5-6mm). According to the division of main use, the lift car sheet metal can be divided into load category, decoration design category, decoration design and load composite category and safety maintenance category.
Elevator car sheet metal processing technology: cutting, stamping die, sheet metal bending and connection
The key raw materials of the elevator industry are various thick steel plates, including thick steel plates, angle iron, round steel, stainless steel plates, cold drawn section steel, etc. When the elevator car company purchases this raw material for production and processing, its key processing technology is also sheet metal processing. The basic manufacturing process of elevator car sheet metal is the same as other sheet metal, with cutting, stamping die, sheet metal bending and connection as the key forming process.
Cutting: general hydraulic plate shears can solve the cutting of elevator car sheet metal
Stamping die: stamping die: applicable to sealing gasket, elevator shaft parts, rib plates and stainless steel head parts
Sheet metal bending: the bending machine commonly used for elevator car sheet metal is dominated by 3m and 4m, with tonnage between 130-250t
Connection: the interface modes of elevator car sheet metal include electric welding (the key is steam maintenance welding and resistance welding), screw connection, riveting (core pulling riveting) and bonding
New technology and process requirements in the sales market
At the moment, when the elevator industry is undergoing transformation and development, the demand for customized integrated elevator shafts and elevator cars has been increased in the elevator transformation of residential areas. The integrated elevator shafts have improved the construction and installation of common steel structures in the middle and late stages of each section, maintaining the integration of steel frame structures and elevators. This is bound to be a strong application of new technologies and new processes for the entire elevator industry.
Multi fixture cold extrusion technology
The multi fixture high-speed punch is a punching machine and equipment that can automatically cold extrude several holes or multiple holes of different specifications. The key technology of the machine and equipment is the development and design of the driver wheel control system and the clamp control system, which accurately ensures the accuracy level of the parts to be processed in the whole process of the punching machine, and greatly reduces the position deviation that is most likely to occur in the accurate positioning of manual services and the luxury waste of comprehensive labor hours. The multi fixture high-speed punch can install several sets of relevant punch molds according to the structure of the holes to be processed, and the number of sets of abrasive tools can be installed according to the number of fixture CNC punches. This kind of hole structure is cold squeezed, and the automatic control system will automatically change the cold extruding of the abrasive tools. The independent innovation has changed the lean production mode that each high-speed punch can only install a complete set of abrasive tools. It is self-evident that the multi fixture high-speed punch has brought economic benefits to improve the efficiency and quality of sheet metal processing, and has greatly reduced the transportation of parts and the installation and adjustment time of various molds. The key is not to place, clamp or precisely position the work that requires manual service, which completely avoids the damage of high-speed punch to human fingers or body. The popularity of multi fixture cold extrusion technology has made many elevator car manufacturing companies compete to purchase multi fixture high-speed punch to improve production and processing efficiency in order to meet the needs of the market.
Fiber laser cutting technology
The technical development of optical fiber laser cutting is to improve the efficiency of production and processing, reduce the capital investment in machinery and equipment work clothes, reduce maintenance costs and avoid accidental injuries. It is the independent innovation pursuit of machinery and equipment manufacturing companies and machinery and equipment application companies that will never stop. The poor performance of the abrasive tools is due to the destruction of the multi fixture high-speed punch during the production process or the largest reduction in the quality of the punching machine, so as to reduce the unexpected cost incurred in the maintenance of the abrasive tools or the removal and replacement of the abrasive tools and the cost of adjusting the machine and equipment. The use of optical fiber laser cutting technology is a replaceable production and processing technology, and most companies have gradually applied it to sheet metal processing. Without the cold extrusion of abrasive tools, it is not easy to report the cost of parts due to damage or fracture of abrasive tools. The key of laser cutting processing is to cut raw materials according to the laser light. Its characteristics are high quality, high specific energy and very good guidance. The quality and efficiency of cutting have been ensured at a high level, and are widely used in the production, production and processing industries of several high-tech commodities, such as airlines, high-speed rail cars, trolleys, medical machinery, etc. The same is true of the elevator industry, which has become very popular at this stage. The basic principle of optical fiber laser cutting is to use the relative density and energy of particle beam to make the metal composite produce gasification, redox reaction and maintain the cutting of raw materials. The optical fiber metal laser cutting machine is mostly used for the cutting production and processing of the elevator car sheet metal components. It is particularly suitable for the production and processing of the elevator car sheet metal components in terms of production and processing quality, maintenance and application. With its advantages of fine cutting seams, smooth and flat wounds, no burrs, small deformation in production and processing, it is very suitable for the production and processing of metal sheet parts, such as the humanized design scheme of the ceiling Non standard design scheme of car wall, many door frames with different construction specifications and processing of sheet metal mechanical parts of various sightseeing elevators. The display and keys of the elevator car control box are highly humanized components that we pursue perfection. Fiber laser cutting can maintain our high quality demand. Optical fiber laser cutting is also used for the production and processing of fish shaped plates, supporting point doors and other components of the electric escalator and crosswalk. If the process is carried out by cold extrusion abrasives, the cold extrusion die cycle is long, and the production and processing are time-consuming and laborious. In addition, the quality of parts will be reduced due to the expansion of the gap after the long-term application of the abrasives. Mold manufacturing is a production and processing plan with increased capital investment costs and maintenance costs, which can no longer meet the needs of the elevator car sheet metal processing market.
Automatic assembly line of sheet metal parts
There are cutting, punching machine, sheet metal bending, electric welding (riveting) and leveling processes in the automatic assembly line of sheet metal parts, because the automatic assembly line of sheet metal parts is the automatic technology production and processing system software for the production and processing of conveyor belt, equipment production equipment and mechanical arm. Under the condition that the production and processing process is complete and correct, if the raw materials have process performance problems or the thickness deviation of raw materials, Or the surface flatness deviation is due to the production of unqualified components, so the following countermeasures must be taken at least to ensure that the raw materials (semi-finished products) produced and processed in each process are qualified, and finally ensure that the components after electric welding are qualified.
