Features and main points of double servo power head tapping and tapping
2022-9-9
In the case of double-servo power head tapping and tapping operations, generally speaking, most of the equipment adopts the automatic feeding and positioning method, especially in application scenarios such as high-precision tapping and drilling.
Tapping - It is a kind of internal thread, screw or tooth button that is processed on the inner side of the hole of various parts with different specifications of through holes or blind holes, such as machine shells, equipment end faces, nuts, flanges, etc. Mechanical processing equipment. Tapping machine is also called tapping machine, thread tapping machine, thread tapping machine, automatic tapping machine, etc.
Tapping - Tapping is to screw the tap into the bottom hole to be drilled with a certain torque to process the internal thread.
General application features:
Tapping
According to the degree of automation of the tapping machining process
Tapping machines can be divided into automatic tapping machines, semi-automatic tapping machines and manual tapping machines;
According to whether the tapping machine drills at the same time when tapping
Tapping machines are divided into drilling and tapping machines, reaming and tapping machines, etc. The automatic tapping machine has the highest degree of automation. When working, as long as the part blank is put into the hopper, it can automatically feed, automatically position, automatically clamp, automatically tap, and automatically unload. One worker can operate multiple devices at the same time. High production efficiency and significant labor cost savings!
High-quality tapping machine has the characteristics of novel design, reasonable structure, easy to use, high degree of automation, easy to use, high efficiency, maintenance-free, and high cost performance. High pass rate.
The high-precision tapping stroke is easy to adjust, and the tapping stroke can be adjusted freely according to the automatic reversing device of the tapping system. It can also be easily adjusted for shallow holes and low processing parts with holes. The double safety device can prevent the damage (broken) of the tapping. , Spindle rotation and up and down, advancing and retreating tools are specially equipped with double safety clutches, the spindle can automatically stop, and the reverse tool will not damage the tool.
The tooth pitch A, B gears cooperate with the A, B rotating shaft and the main shaft to advance completely according to the tooth pitch, and the vertical stability, precision, and precision are particularly high. At the same time, depending on the quality of the processed items, it will not cause threads of different thicknesses, and it can also tap perfect threads for thin plates, light alloy metals, synthetic resins and other soft products. At the same time, it can also be equipped with a multi-axis device for multi-axis simultaneous processing, which greatly improves the production efficiency.
useDouble servo tapping power headThere are many advantages and advantages, mainly the following advantages
1. The spindle advance and retraction is set by the system numerical control, the spindle servo and the feed servo are precisely coordinated, and the closed-loop precision of the whole process is extremely high.
2. After the operator sets the required parameters such as tooth spacing and depth, there is no need for manual intervention.
3, can be used for high-speed continuous cycle operation, durable.
4. Beginners can also get started quickly, and the program is intuitive and simple.
5. The adjustment of high-precision tapping stroke is simple.
6. Matching the inspection and gauge parts can prevent the breakage of the tap.
7. The cooperation of multi-axis tapping machines can produce high-efficiency operations.
Tapping points
(1) The hole of the threaded bottom hole on the workpiece should be chamfered, and both ends of the through-hole thread should be chamfered.
(2) The position of the workpiece clamp should be correct, and the center line of the threaded hole should be placed in a horizontal or vertical position as much as possible, so that it is easy for tapping to judge whether the axis of the tap is perpendicular to the plane of the workpiece.
(3) At the beginning of tapping, try to put the tap as straight as possible, then apply pressure to the tap and turn the twister. When cutting in 1-2 turns, carefully check and correct the position of the tap. Generally, when cutting into 3-4 turns of thread, the tap position should be correct. Afterwards, you only need to turn the wringer, and you should not put pressure on the tap, otherwise the thread profile will be damaged.
(4) When tapping, every 1/2-1 turn of the twister should be reversed about 1/2 turn, so that the chips can be easily discharged after being broken, and the phenomenon that the tap is rolled by the cutting edge due to sticky chips can be reduced.
(5) When encountering a screw hole that cannot be tapped, withdraw the tap frequently to remove the chips in the hole.
(6) When tapping the screw holes of plastic materials, lubricating coolant should be added. For steel materials, oil or emulsion with high concentration is generally used, and rapeseed oil or molybdenum disulfide can be used for higher requirements. For stainless steel, use No. 30 motor oil or vulcanized oil.
(7) When changing to the next tap during the tapping process, screw it into the tapped thread by hand first, and then turn it with a twister when it can no longer be screwed in. When the end cone is finished tapping and exiting, it is also necessary to avoid rapidly turning the wringer, and it is better to unscrew it by hand to ensure that the quality of the tapped thread is not affected.
(8) When machine tapping, the tap and the screw hole should be kept coaxial.
(9) When the machine is attacking, the calibration part of the tap cannot all come out, otherwise there will be random teeth when the tap is withdrawn from the back.
(10) The cutting speed during machine attack is generally 6-15 m/min for steel; 5-10 m/min for quenched and tempered steel or harder steel; 2-7 m/min for stainless steel; 8 for cast iron -10 m/min. For the same material, the smaller the tap diameter takes the higher value, and the larger the tap diameter takes the lower value.
