1. Mould industry trends: ① Competition in the mould industry is becoming increasingly fierce. ②The production cycle is shortening day by day. ③ Keep improving the quality of molds.
2. At present, the prevailing situation in the domestic machining industry: 1. EDM machine tools are aging, and backward managers will only complain about the poor performance of the machine tools or the small number of machine tools, instead of tapping the potential of existing equipment and processing technology, 2. Electrodes The design, manufacturing, and electrical discharge machining of a line of process management is scattered, and the coordination is extremely poor, resulting in the rapid transfer and execution of various processes. 3 The non-standard tooling and fixture for EDM ceramic standard ball has always been manually checking the electrode, and it is cumbersome and slow! 4. The electrode design is not standardized, and multiple standards cause electrode material waste. The processing technology of the enterprise is in a state of development. This is a Great drawbacks, hidden dangers! 5. Low electrode clamping efficiency. Long electrode calibration time, an average of 10 minutes for each electrode. Long electrode centering time, an average of 5 minutes for each electrode. Long electrode reexamination time, and an average of 2 minutes for each electrode. After using the precision positioning fixture series, it can be quickly clamped and produced in 1 minute. Drawing on international advanced management concepts, advanced technology research and development of precision positioning erowa fixture series is committed to improving the absolute utilization rate of EDM machine tools, reducing human factors, rationally standardizing operating procedures, reducing labor costs, eliminating machine tool resource waste, improving mold quality, and shortening mold production cycle , Improve the competitiveness of enterprises!
The special force precision positioning system not only has the function of locking and positioning, but more importantly, it can locate with high progress accuracy and avoid repeated centering and correction.
The locking principle of the system: the locking mainly relies on the joint action of the steel ball, the turntable and the pull nail. There is a ball lock groove with a slope inside the turntable. When the air valve is opened, the air pressure is greater than the pressure of the spring on the turntable. The turntable moves upwards. The steel ball hole of the inner wire just corresponds to the ball lock groove of the turntable. The steel ball has enough space to move. The chuck or workpiece of the pull nail can be easily placed in the chuck. When the air valve is closed, the pressure of the spring is greater than the air pressure, and the turntable moves downward, and the steel ball and the inclined surface of the turntable and the snap ring of the pull nail form a clamping effect. Production benefits brought by positioning precision fixture system:
1. Speed reduction and preset time. During EDM, CNC, EDW processing, the clamping room is about 10 seconds, only one centering is required, and there is no need to hit the meter, touch the number and center for subsequent work.
2. Accuracy static energy tolerance repeat accuracy ±0.002
3. Reduce machine tool investment. Due to the reduced pre-adjustment time, the number of machines invested by customers is also relatively reduced, and the planned production efficiency is not affected, and investment costs are reduced.
4. Reduced personnel investment. Under the circumstance that the time for pre-adjustment is reduced, human resources are allocated more reasonably.
5. Reduce thought mistakes The positioning precision fixture system adopts the concept of automation and standardization, reduces thought mistakes, and effectively improves productivity and production quality.
6. Increase the utilization rate of the machine tool. After the DNC processing is completed, it can be disassembled. It does not require the number of cards on the machine tool and can continue to process other workpieces. It is very convenient to rework and re-clamp.
7. Effectively improve the utilization rate of machine tools.
8. Convenient and safe maintenance. When the mold needs to be repaired or reworked, it can be started by re-fixing. The copper male seat is directional and will not cause a wrong direction.
