According to ICTE~(COM) using ICTE~(AutoMag) system atmosphere furnace and vacuum

0 Introduction Different process and quenching equipments from different years can automate equipment areas. They are actually different, but the process conditions in software must be implemented like a single equipment. The following are these devices: It makes sense to turn and control by the center. According to TS16949 in Quenching 1) No. 5 manual production line, vacuum furnace and atmosphere furnace, 610mm wide workshop added process steps can be used as a description of the process, as part of the quality management system, to be evaluated and incorporated into the central data acquisition system, and Pass the document to the customer. This has been done with the ICTEAutlMag/H system in the quenching room of ABH Beerger Quenchtechnik GmbH.

The Berger Group has international entities and manages production facilities in Germany, Canada, the United States, Poland, Switzerland and India. In Memmingen, Germany, Berger Holding GmbH manages the Berger Group's business.

1 INTRODUCTION ABHigger Quenching Technology Co., Ltd. is a member of the company Beiger Holding Co., Ltd. In addition to quenching, Berger Holding also engages in the manufacture of precision machined parts, machining-free technology, the manufacture of mechanical tools and precision machinery used in these processes.

ABHBerger Quenching Technology Co., Ltd. started its development in Ottobeuren as a division of Berger GmbH. In 5:00, in the quenched train room of Ottobeuren, there was a No. 5 multifunctional box furnace production line (charging size: 610mmX910mmX610mm, 500kg); Taiwan VTCC type vacuum furnace with high pressure gas quench; a HUttinger induction hardening furnace.

In the new location, the following items were added: No.8 full-featured production line (charging size: 760mmX1220mmX610mm, 600kg); VDR-type cryogenic muffle tank vacuum furnace.

In 2002, it agreed to add more workshops to the quenching trains and begin expansion work. At the same time, considering the flow of materials and the sequence of operations of the equipment, this project is unique in that it is necessary to establish an actual and logical link between the existing No. 8 production line and the planned No. 10 new production line.

In the new plant, Mult-I-cell open-ended full-featured manual No. 5 manually operated production lines include: a) VTCC vacuum furnaces;) VDR type muffle tank vacuum furnaces;) No. 5 multi-function gap furnace production line , Including: 1TQ-5 type furnace; 2WPSD-5 type cleaning machine; 3DL-5 type tempering furnace; 45# charging vehicle; 55# loading and unloading vehicle; 6DAC-5 type nitrogen annealing furnace; 2) Connection 8 No. 10 and box furnace production line.

No. 8 multifunctional box furnace production line (1 910mm high). 1RTQPF-8I furnace; 2RTQPF-8 furnace; 3DAC-8 atmosphere nitriding furnace; 4DL-81 tempering furnace; 5DL-8 tempering furnace; cooling chamber and heating chamber No. 68; 78 VaioClean water base washing machine.

No. 10 multi-purpose box furnace production line (1 high) (). 1RTQ-10(S) type I furnace; 2RTQ-10(S) type furnace; 3DAC-10(S) type protective atmosphere nitriding furnace; 4DL-10(S) type I tempering furnace; 5DL-10(S) Type tempering furnace; No. 610 cooling chamber and heating chamber; 7 special 95*C hydrocarbon cleaning machine.

The space furnace also has space, and the equipment purchased during the two years of view is 2002~3) Mult-I-cell multi-chamber vacuum furnace production line (No. 5).

Installation in 2003 'The quenching technology company has now had an empty furnace; b) HT/519 1 vacuum high temperature furnace; c) QGP type high pressure quench furnace; d) VDR-514-E type low temperature vacuum nitriding furnace; e) Cooling and tempering chamber #5; f) VacMoba-519 loading and unloading unit.

Extensive heat treatment is possible, including annealing and tempering, nitriding, nitrocarburizing and carbonitriding in controlled atmosphere furnaces or vacuum furnaces, controllable supply of data; all process maps are to be drawn through all production lines; According to the above received to control, monitor, detect and provide information for the entire operation of the quenching room.

2 Automate different systems with ICTEAut°Mag to No.5 manual atmosphere furnace and vacuum furnace production line with ICTE*"11 system, which can automatically plan the loading and unloading of different furnaces on this production line, monitor and record data (see) On the manually operated Line 5, all loading, unloading, and various operations are manual, and on the 8th and 10th and multi-room automation lines, once the charge enters the system at the designated entrance, ICTEAutlMag manages these operations. The No. 8 and No. 10(S) automated production lines are equipped with the AutoMag system, which has some features (see below) that were implemented as an implementation of the ICTEmM system in 1995 on the existing production line No. 8, installed in 2003. Line 10 not only uses process data, but also actually interconnects the furnaces. These lines operate like a single production line throughout the entire network. Charges 8 and 10 have different heights and are automatically detected at the loading point, and Considering the distribution procedure of the furnace charge, in the combined production line, there is a separate working zone and a specified atmosphere furnace or vacuum furnace carburizing, and cooling, oil quenching or high in the atmosphere Gas quenching, and quenching and tempering process of the tool steel.

In the system, our goal is to provide all the production lines at the control center. At the same time, two loaders are working to facilitate the effective operation of the production line. In addition to the combined operations, these devices can also operate independently. Because the two loaders are centrally controlled by the system, if one of them is broken, we can switch to a single load. In this mode, when one of the loaders is under repair or work, the other one is Can take charge of the entire production line. When the two AutoMag modes are selected, each production line can also be run independently. This design concept allows ABHBejger Quenchtechnik to have the maximum efficiency and flexibility in practical use.

The total length of the combination of the 8 and 10 production lines is about 50m, which puts forward high logic requirements for our internal management and material flow. One solution is to provide an easy-to-pass feeder route with a bulkhead system.

The automatic vacuum furnace production line (see) combines each vacuum processing unit with a separate quench unit, a cryogenic vacuum furnace, a cold treatment furnace, and a tempering furnace. Transportation of loading and unloading vehicles, between systems and within the system, is managed by VacMobil and can be heated and evacuated. Separating the actual high-temperature vacuum treatment from the quenching enables the equipment to be extremely flexible and ideally high in output.

The high degree of automation of the Tian 6 automatic vacuum crucible production line equipment enables each unit to operate independently from each other and can efficiently use various functions of the equipment. This equipment is designed to operate automatically, as long as a sufficient amount of charge is prepared in advance and the charge is stored. The station equipment can be operated unattended in a fully automatic way at night and on weekends.

The entire production line is monitored with a remote protection system and an error alarm is issued to the operator when an error occurs in the management device.

In the manual operation part of the equipment, the semi-automatic charging and distribution system ensures high efficiency and strong time management, and the files are automatically prepared and executed by the furnace, for example: quenching in a multi-purpose box furnace and tempering in a tempering furnace.

3 Controlling the quenching room with the ICTE AutoMag system In addition to recording the actual time and process of heat treatment equipment, customers now also require a clear record of the various processing steps performed by their products from the time they enter the quench room to the time they leave. These steps include Goods inspection, preparation, batching, entering heat treatment process (containment, packaging, and shipping. Quality management (QM) system now performed by ABH and its customers, requires complete documentation, and records as a complete, tightly bound chain. Under each aspect of the above operations, AutoMag records data for each item of equipment that is available on various furnaces.

Processing with several devices (that is, successively processing on different devices) was performed separately in the past during the execution of each function of the device. These separate records and their printouts must be manually attached to special parts. Tests and test reports, a variety of operations and other processing steps must also be performed manually outside the actual quenching equipment.

Thanks to the new ICTECM software and the corresponding ICTEAu" or ICTE*H system, we can use software technology to put all devices on a unified starting point. This unity has the following advantages: 1) The new and old systems all reach the same software 2) In the control room, all systems can be quickly and easily reviewed.3) Create and edit incoming control programs with user names and passwords or barcode cards, including the user's record files (name, time, matter, location). 4) The processing steps of different parts of the equipment are linked together with the task card (Table 1) 5) The equipment is manual and automatic, and the equipment can only start the next operation after accepting the previous operation. In a system (incoming instructions, programming tables, implementation, quality assurance) 7) Programs can be created and managed centrally for different devices. These programs can also be assigned to different components.

Programs, all customers and all their products. These heat treatment procedures consist of a single program for different furnaces. The individual steps in these furnaces are programmed with the special furnace AutoMag. Individual processes within a single furnace are incorporated into the heat treatment schedule.

When creating a product, assign it a heat treatment schedule, related test and inspection plans, ingredients instructions, and corresponding customers. You can also assign photos or general information about the processing method to the product. Therefore, these product data contain a complete quality management plan: 1) All the operations that the heat treatment schedule component undergoes. 2) Operation instructions. 3) Dosing instructions. 4) Test plan: a) test quantity (number) b) sampling point of the component;) type and method of test; d) expected test result. 5) Packaging instructions and other information.

Once the task is entered and the product is created, it is usually necessary to print a bill of materials for the charge, which corresponds to the travel of the charge through the quench train. The steps that must be manually operated are confirmed by the operator. The automatic operation requires a special machine to make a task card, list the heat treatment steps that the machine may need to engage in, and step VIII of the mlishi line after the machine is released. This | step is automated by the machine. Confirmation.

(Be it manual or automatic) to begin.

The operations that have been performed can be observed in the ICTEM system at any time in their flow chart (see Table 1). Once all the operations in the processing schedule are completed, the system generates a test report for the product to the customer.

There are processing schedules for the start and end time. Its condition can be queried at any time. We can provide customers with 5 procedures for processing procedures. Use the ICTECOM system. In a central control room with a major database, use different technologies and manual operations to make Different manufacturers' production equipment forms a network. The structure of the COM system is the same for all functions of the equipment, and the customer can receive the documents of the whole process, and the document records the complete route through which the charge or product passes through the quenching train.
