Description
Technical field
The utility model relates to machining tool technical field.
Background technology
In the past because HB500 steel plate is harder, reach HB500, and the hardness of common fluted drill was between HB600-HB650, cannot carry out Drilling operation to this type of steel plate.Even if use alloy cutter head, requirement can not be reached.At present, what generally adopt is import cutter head, and a hole needs with large spot facing cutter, little spot facing cutter and taper hole cutter three cutter.First process the larger hole of a certain depth, then process a less through hole with less milling cutter, finally mill out tapered hole with angle cutting tool.Profit is processed in this way, and need three cutter, need process 3 times and just can complete, long processing time, time-consuming, working (machining) efficiency is low; And no matter be handle of a knife or cutter head, all very expensive, processing cost is high.
Utility model content
The purpose of this utility model is to provide a kind of steel plate composite drill milling cutter, the Drilling operation that can will need repeatedly carry out, a kind of cutter is used to complete, not only crudy is good, and decreasing operation, saving of work and time is laborsaving, substantially increases working (machining) efficiency, reduce cost, alleviate the labour intensity of workman.
Main technical schemes of the present utility model is: a kind of steel plate composite drill milling cutter, is characterized in that: comprise knife bar, center bit, endoporus cutter head, reaming cutter and taper hole macropore cutter head; Described knife bar is divided into epimere and hypomere, and the diameter of hypomere is less than the diameter of epimere; Center bit is fixed on the center of hypomere bottom surface, and endoporus cutter head and reaming cutter are all fixed on the following side of hypomere; Taper hole macropore cutter head is fixed on the following side of epimere; Center bit is used for location and gives boring, and endoporus cutter head is for cutting the centre of aperture, and reaming cutter is for cutting the surrounding position of aperture, and taper hole macropore cutter head for cutting taper hole and processing macropore on aperture.
Preferably, described knife bar is also provided with and bores milling dop.
Preferably, described center bit, endoporus cutter head, reaming cutter and taper hole macropore cutter head are all fixed on knife bar with screw.
Preferably, described taper hole macropore cutter head becomes 90 degree of positions to install with endoporus cutter head at the circumferencial direction of knife bar, and taper hole macropore cutter head becomes the position of 180 degree to install with reaming cutter at the circumferencial direction of knife bar.Object is: prevent the resistance in process from concentrating, and reduces the spoilage of cutter head, reduces the vibration of process equipment, improves the service life of equipment.
Preferably, described steel plate is HB500 steel plate, drill bit or the cutter head of the material of described center bit, endoporus cutter head, reaming cutter and taper hole macropore cutter head to be professional workhardness the be bass 500 steel plate Hardmetal materials of HB500.
Good effect of the present utility model is: the deficiency overcoming prior art, the Drilling operation that need repeatedly carry out, and uses a kind of cutter to complete, especially carries out Drilling operation for HB500 steel plate, uses a kind of cutter to complete.Not only crudy is good, and saving of work and time is laborsaving, substantially increases working (machining) efficiency, reduces cost; Alleviate the labour intensity of worker.
Be described in further detail below in conjunction with a good embodiment and accompanying drawing, but not as to restriction of the present utility model.
