Abstract
The utility model relates to a tubular cutter. One end of the tubular cutter is provided with a groove. The end surface and the inner part of the groove are coated with diamond granules. The tubular cutter of the utility model has novel structure and can save large quantity of material. The utility model is especially suitable for punching holes on Nd-Fe-B magnet steel.
Description
The utility model belongs to metal cutting tool, especially for the cutter of punching.
The metal parts punching generally all is to use drill bit punching on the drilling machine or on lathe.The material of getting in the hole has plenty of the bits shape, has plenty of powdery.The material of being got that punches generally all can't utilize, and at some in particular cases, needs the material of punching harder and crisp, and punching with drill bit workpiece cracking, material change performance to occur being perforated, and punching speed is very slow.
The purpose of this utility model provides the Tubular tool of material in a kind of reusable aperture.
Main feature of the present utility model is the end fluting of Tubular tool, is coated with a diamond grain in end face of slotting and groove.
The utility model cutter structure novelty can be saved lot of materials, is specially adapted to the Nd-Fe-B magnet steel punching.
Description of drawings
Accompanying drawing is the Tubular tool structural representation
1 is cutter hub among the figure, the 2nd, and cutter groove, the 3rd, cutter end face
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Known that by accompanying drawing cutter hub 1 is a tubulose, material therefor is a metallic steel, has some grooves at an end of tubulose cutter hub, slot be at least a pair of.It is relatively good to open 5 pairs of grooves on circumference, along with tubulose cutter hub diameter increases, can open more groove on the circumference.On the end face 3 of Tubular tool He in the groove 2, plate a metal stone grain, with guarantee the intensity of the diamond that plated a grain coating.The cutter groove depth is 5-10mm, and groove width is 0.1-0.2mm.The wall thickness of tubulose cutter hub is divided into two parts, and first is a slotted line, and the wall thickness of the body of this section is 0.1-0.3mm, and the second half section of body, promptly the pipe thickness of unslotted part is bigger than the pipe thickness of slotted section.Generally increase along with the Tubular tool diameter, wall thickness is corresponding to be thickened, and allows the intensity of cutter hub with the guarantor.A diamond grain of plating in tubulose cutter hub end face and the groove, a granularity is the 80-120 order, preferably 100 orders.The utility model is the diamond tool of a tubulose, cooperate the high speed rotation of the workpiece that punches, punching speed is compared with the punching of calipers drill bit and can be improved about 5 times, drilling precision improves greatly, after particularly punching finishes, exist the material in the tubulose cutter hub to reuse, saved a large amount of raw material.
