Automation is a necessary measure to improve produ

Automation is a necessary measure to start looking for images with low-power objective lens and high productivity. There is no doubt that at present, automation is an important method to compete with suppliers from low wage countries in mold and box manufacturing. But this does not mean that we should realize automation at all costs. Sometimes we can understand the automation process more simply, such as using a simple electrode and workpiece processing system to improve the processing process

in the past two years, according to Mr. Hirschmann, an expert in fastening system of fluorn winzeln company, people are increasingly looking for complete automation solutions, that is, connecting with the whole electromechanical workshop through one or more manipulators or processing systems. The significance of this for tool manufacturers can only be realized when they are manufacturing these equipment

when Owens Corning connected many different machines as early as 4 or 5 years ago announced that the production capacity would not be increased by the end of 2015, he connected the 3D measuring instrument through the embedded electric corrosion milling, and then the data would be transmitted to each single machine, so that the next process would not stop - it is often forgotten that the other method is very accurate and simpler. Everyone who designs production automation should ask the following question:

- is it really better to connect all machines? Or can it form a smaller production unit

- is it really meaningful to connect manufacturing forms with completely different processing times

- should we solve the technical functions at the high end, or pay attention to those units with the highest production capacity and great economic significance

the electric corrosion machine is equipped with a simple processing system

Mr. Hirschmann proposes two processing methods for all automation problems: eRobot and 6-axis manipulator. ERobot is the simplest way of workpiece or electronic processing. Figure 1 is this "plug and play" way. A buried or electric etching machine or a milling machine can replace electrodes and workpieces in this simple way

for tasks with higher requirements, Mr. Hirschmann uses a 6-axis manipulator made by FANUC Robotics (Figure 2). It can carry out single machine or multi machine operation of various models, and automatically install workpieces and electrodes. It should be emphasized that, especially when the electric etching machine equipped with a 6-axis manipulator is used for production, unexpected additional functions will appear (Fig. 3), and the high flexibility of this manipulator can also be competent for difficult transposition work

manipulator undertakes high requirements

the production workshop can use the device of 6-axis manipulator for the production of one, two or more machines. In multi machine equipment, Hirschmann's research focus is mainly on the coordination of production process. We must master this process well, and we cannot stop all production just because of a fault. Therefore, Hirschmann suggested that enterprises "review the people who bind themselves to automation"

if you correctly understand and use automation, you will certainly obtain good economic benefits. For example, by installing different workpieces in the automation system of an HSC milling machine, a simple work management system can be connected (Figure 4)

Figure 4. The benchmark system prisfix is composed of four Z parts, four benchmark prisms (a) and a die handle (b)

in addition, from an economic point of view, automation should be combined with new technologies that do not require high costs and costs. For example, automated PKD etchers and rotationally symmetric cutters equipped with PKD or CBN blades can be operated unattended. Users can get a complete set of automatic production equipment at the price of traditional tool grinder. When the tool blank is put into the tool library, the program of specific cutting shape will be ready. When the various parts of the equipment begin to work, the next tool blank together with the relevant program is ready. The same is true of the line etcher, which uses unmanned operation to produce milling tools

automation equipment improves productivity

single machine or multi machine automation can improve the productivity of an enterprise. Its investment is often lower than other options. Only the workpiece or electrode fixture must be able to be replaced reliably and accurately

as the new benchmark system prisfix developed by Hirschmann shows, when it comes to the benchmark of electrodes and small workpieces, less is more. This is a simple type of benchmark. However, enterprises also have many ideas and doubts about this. The R & D Engineer first raised the question: does the embedded electric corrosion machine or HSC milling machine necessarily need a very expensive accompanying fixture. In fact, the software of the experimental machine has been developed unprecedentedly. Finally, the follow-up fixture is only used as a unified benchmark. It is only a foundation through which an electrode or workpiece can be transported from one processing process to the next. This kind of conveying can be manual or automatic, and the pre adjustment of workpiece and electrode can also be completed on it. It is important to have highly accurate positioning and repetition accuracy. The new benchmark system prisfix no longer requires a follow-up fixture, which is composed of four Z parts and four x-y-benchmark prisms, and its work is relatively simple. A hole diagram is made on the electrode or small workpiece: four 5mm diameter holes are used to clamp the benchmark prisms, four screw holes M5 are used for Z parts, and another screw hole M12 × 1.25 for clamps. Z parts and clamps are screwed and fixed. Fix the x-y-reference prism into a 5mm diameter hole with hardenable adhesive, and clamp the electrode or small workpiece with a clamp. The prism conforms to the form of the clamp and obtains its position, which is then quenched with adhesive

Figure 5. Will the system structure with graphite and copper electrodes of the reference system prisfix be firm? In this regard, the manufacturer stressed that sufficient tests have been carried out on both the electrode group and the production of HSC milling machine with the new benchmark system. The experimental results show the special robustness of the prisfix system, which is unmatched by the traditional follow-up fixture system with reduced lubrication. This material quenching method can be firmly connected with the workpiece or electrode through installation. Displacement can also be excluded by using multi-layer material combinations. (end)
