he tapping machine is a machine tool for machining internal threads, screws, or tooth buckles on the inner surface of the holes of various holes or blind holes with different specifications, such as the shell of the machine parts, the end face of the equipment, the nut, the flange plate and so on. Suitable for automobile or motorcycle body, frame, chassis, connecting rod, engine, cylinder and various mechanical parts, machine tools, hardware products, metal pipe, gear, pump body, valve, fastener and other parts processing. The following is a brief introduction of the characteristics and points for attention in the following aspects:
First, the characteristics of the tapping machine
(1) teeth with fast speed, high accuracy and attack can be examined by dental examination.
(2) high precision tapping stroke adjustment is simple, automatic reversing device can freely adjust tapping stroke, and shallow hole and hole low machining parts can also be easily adjusted.
(3) the double safety device can prevent the damage of the screw attack, the spindle rotation and the upper and lower, the return knife special double safety clutch, the spindle can automatically stop, the reversing knife will not damage the tool.
(4) the shaft is fully coordinated with the main shaft in accordance with the tooth distance, and the vertical stability, precision and precision are especially high.
(5) it can be operated continuously at high speed, and the special motor can be durable and automatic.
(6) the operator can leave the machine completely, and the beginner can operate smoothly. One person can operate multiple devices at the same time, which can significantly save labor costs.
Two. Attention to the operation of the tapping machine
(1) the position of the work piece of the full automatic tapping machine is correct, and the center line of the threaded hole is placed in the horizontal or vertical position as far as possible, so that the tapping is easy to judge whether the axis of the tapping is perpendicular to the plane of the workpiece. The hole of the threaded bottom hole on the workpiece is chamfered, and both ends of the threaded hole are chamfered.
(2) the taps should be placed as far as possible at the beginning of the attack, and then the taps are added to the taps and the wrench is rotated. The position of the taps should be carefully checked and corrected when the taps are cut in. The taps should be correct. In the future, it is necessary to rotate the wrench instead of adding pressure to the tap, otherwise the thread form will be damaged.
(3) the taps and screw holes must be coaxial when tapping, and the calibration part of taps can not be all out, otherwise they will produce random teeth when they exit the tap. The chips can be easily broken off and broken, and the cutting edges can be reduced due to sticky chips. When you are unable to get through the screw holes, you must quit the tap and remove the chips in the hole.
(4) when changing a tap in the process of tapping, use your hands to spin into the tapping and thread, until you can’t screw in, and then use the wrench to turn. When the end cone is finished, it is also necessary to avoid rotating the wrench rapidly. It is better to use hand to spin out to ensure the quality of the thread has not been affected.
(5) special tapping oil should be used when drilling holes in plastic materials. For ordinary carbon steel, copper and aluminum alloy and other materials, the general machine contains tapping oil from lard. For stainless steels and titanium alloys, high extreme pressure tapping oil containing sulfurized fatty acid esters is the best choice.
(6) the cutting speed of the automatic tapping machine should be adjusted according to the different material. When the same material is used, the tap diameter is higher and the tap diameter is larger.
