SCIENTIFIC SOCIETY OF MECHANICAL ENGINEERING GÉP Voi. 38. No. 1. 1—52. JANUARY 1986. Lakatos, Péter— Hadházy, P.: Development of washing technologies and washing machines.................................................................................................... 5 As a result of the development work there have left washing machines of reliable quality, lending themselves for large serseries production, the straight lines of the Works Hajdúsági Iparművek, and are locked for in both the country and export markets. These are the most recent varieties of conventional washing machines, having direct drives. The new models of the type series of automatic washing machines are provided with novel washing processes owing to Incessant development work. The structural and controlling elements of the machines suitable for performing up-to-date washing programmes are also subject to continuous development. Barbócz, Károly: Development of sheet-radiators............................................. 13 An up-to-date type series of sheet-radiators has been developed, fit for export, at the Works Hajdúsági Iparművek. Actually they are concerned with a continued development of sheet-radiators with increased heating capacity, as well as modernization of headpieces. manual welding precticed hitherto had been mechanized through putting into service a single-purpose machine built for this purpose, and consequently a better quality ensured. The single-purpose machine for welding pipings permits, due to the design with two work sites, continuous work and high productivity. Sipos, Iván: Results of the development of material handling..................... 35 Author surveys the tasks arising in consequence of adverse siting conditions, solving of which resulted in favourable circumstances for mass production. Pótor, Béla: Ensuring quality and quality control at the Works of Hajdúsági Iparművek............................................................................................................ 38 The quality of production and of the completed product of household appliances has been continually in competiotion with the users' requirements throughout the entire world and this true equally for our works. In factory management quality and production cost are in interaction and securing compatibility requires continually new methods. The paper reviews these methods as used at the Hajdúsági Iparművek, laying emphasis on the importance of planning, ensuring, managing and developing quality. The integrated quality management system, as adopted, its results and the technical control activities actuating the system are dealt with in detail. Somogyi, József: Features of production technology, main results of the development, and objectives ahead.................................................................. 15 The Works Hajdúsági Iparművek, an important factory of household appliances, even on an European level, manufactures a number of products in licence and in co-operation, respectively. Recently a complex development has been achieved, extended to the entire production system. The paper deals with the main features of development in chronological order and according to technological branches, with the already introduced production system, as well as with further conceptions. Kovács, Ferenc: Production engineering at the works Hajdúsági Iparművek ........................................................................................................................... 17 Owing to their up-to-date products and technologies, the works Hajdúsági Iparművek became member of the ,,Club of the Hundreds". The paper expounds, from the viewpoint of economic engineers, the complex micro-economic system, experience and problems of production engineering, and possible alternatives for the reconciliation of contradictions between principles and practice. Németh, László: Design and execution of means of production................ 20 Development of the production pf an enterprise, consistent good quality of production can only be obtained in case of adequate tooling. The paper contains an overview of a "transferized" series production in the manufacture of deep-drawn parts. Horváth, György—Kállai, Imre—Tóth, András—Papp, József: Hotenamelled hot-water reservoirs.......................................................................... 24 Taking account of hot-enamelling processes used hitherto, the paper demonstrates the hot-enamelling technology elaborated at the Works Hajdúsági Iparművek, whlxh lends itself for the anticorrosive protection of parts of household machines and of hot-water reservoirs. Lesnyák, Miklós: Production of welded hot-water reservoirs..................... 29 The paper deals with the best suitable constructional elements for the technological operations of welding, as well as of enamelling, and subsequently with the technological system of tank-welding. Kiss, Antal: Welding cold and hot-water piping of hot-water reservoirs by a single-purpose machine............................................................................... 31 In the production of hot-water reservoirs the qualitative requirements can be satisfied through mechanization of welding work. Therefore the \ Czeglédy, Lajos—Pintye, Zoltán—Veres, István: Processing broad band steel on a CNC sheet trimming machine.......................................................... 33 At the Works Hajdúsági Iparművek there has been realized a processing system of unfolded broad band rolls. Sized boards or straps are produced on a CNC trimming line. Actuation of the trimming blades situated vertical to one another, tasks of the infeed and stacking system are controlled by a computer Model Siemens. Recording the unfolded parts, the materials, optimation of trimming work are done by an addition IBM computer. Görög, Mihály—Molnár, József: Automated system of final acceptance . 42 The publication expounds the equipment Model AVB—MA for final acceptance, developed in co-operation by HIM—ATOMKI (Works Hajdúsági Iparművek — Nuclear Research Institute), supported by OMFB (National Board for Technical Development), in service at the assembly of automatic washing machines. The paper contains description of the build-up, the operation and the fields of application of the equipment. Analysis of integration of the equipment so developed into the system, examination of the feasibilities and limits of continued development. A possible solution of computer-aided processing of subjective test results under plant circumstances is being dealt with. Molnár, Sándorr Crucial points of development and investment activities .................................................................................................................................... 45 The paper contains a summary of developments in production technology and infrastructural domain performed at the Works Hajdúsági Iparművek during the period of the 6th Five Years' Plan. Tóth, Mihály—Hegedűs, Gyula: Development of the information system at the works Hajdúsági Iparművek..................................................................... 46 The paper reports about results of establishing a basic information system required for the introduction of a computer-aided production dispatching system of a medium-size typical enterprize of machine industry, as well as on the subsystems actually realized. Subsequent to expounding modules of the individual subsystems, some ideas in outlines are furnished on the concept of a complex information system, satisfying qualitatively higher requirements of the trends of continued development.
