Stamping elbow of two cold stamping and hot stamping, cold stamping usually selected according to the material properties or hot stamping and equipment capacity. Before stamping, tube placed on the lower die, the inner core and the end of the tube into the mold, the mold pressing downward movement started by the constraints and within the outer mold mold supporting role to make elbow shape. Compared with hot push technology, the appearance of the inferior quality of the former stamping; stamping elbow while forming outside the arc in tension, no other parts of the excess metal to compensate, so the wall thickness at the outer arc of about 10% to about thinning . However, as for single-piece production and low cost, it is used for stamping elbow process small quantities, thick-walled elbow manufacturing. Due to poor high viscosity material stainless steel elbow stamping elbow manufacturers, chip breaking performance, and therefore the use of stainless steel stamping elbow tap tapping process prone to scratching the workpiece thread or tap chip chipping phenomena such as high alloy steel stamping elbow, affect processing efficiency and thread quality. In order to extend the life of the tap, thread processing to improve the quality, should note the following points: 1, design and manufacturing tap (1) selection of better tap the material. Add special alloying elements in ordinary high-speed tool steel, can significantly improve the wear resistance and toughness tap. (2) a reasonable choice of tool heat treatment methods to tap both hardness and toughness. (3) appropriate to increase Taps front corner. It should be noted stamping elbow, such as tap rake angle is too large, resulting in the retraction easy tap-tapping out chipping and threaded multi-row. (4) In the tap thread coated titanium nitride coating can significantly improve the wear resistance of the tap, the heat resistance and lubricity. (5) appropriate to increase the amount of tap shovel back. It should be noted, such as the shovel back excessive retraction prone when the phenomenon within the chip into the corner tap, tapping out the thread and poor finish. 2, the choice of tapping oil on stainless steel elbow pipe tapping stamping process, the choice of tapping oil is also very important. Tapping oil must have good cooling, lubrication and rust-proof function. If tapping oil lubrication ineffective, then tapping the thread finish is poor, and tap tapping large resistance. If tapping oil cooling effect is not good, then tap easy to stick tooth steel stamping elbow suppliers, ie tap thread and easy to bond stainless steel rake surface chips. Stainless steel special tapping oil is better, can be used directly. In addition, oil may also be tapping spirits and self-configure, but the ratio of fixed to the right. Slurry industry engaged in machining tool selection slurry domestic production as well as its accessories processing enterprises are facing the problem of machining tool of choice.
