Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Change as shown in Figure 2,3 and amendment.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
As shown in Figure 2,3, multi-ladder contoured reamer 100 of the present utility model comprises: cutter hub 10, be formed at the cutter head 20 of cutter hub one end.Wherein, the helical angle of cutter head 20 is 13 ° ~ 18 °.Setting like this, make multi-ladder of the present utility model shaping expansion bulk strength higher, chip breaking is better.
The end of described cutter head 20 is formed with the first cutting edge 21, and described cutter head 20 is also formed with some reamer 22.Described first cutting edge 21 pairs of machined materials carry out cutting perforate, and the size of multiple reamer 22 to the hole offered is widened, and forms trapezoidal hole structure.Wherein, described first cutting edge 21 is R type.In described adjacent reamer 22, the diameter away from the reamer 22 of described first cutting edge 21 is greater than the diameter of the reamer 22 near described first cutting edge 21.Thus some reamer 22 form forge piece of step type structure.Further, the wall that described cutter head 20 contacts with the hole wall of the described shoulder hole be processed to form forms the forming surface of described cutter head.Thus various structures drill bit is combined with corresponding shaping face by it, can the corresponding shoulder hole in the shaping place of time processing, working (machining) efficiency and machining accuracy high.
Described cutter head 20 also offers chip area 23, and described chip area 23 extends to the other end from one end of described cutter head 20, and the edge of described chip area 23 forms the second cutting edge 24 of described cutter head.Described second cutting edge 24 is formed at the side of described cutter head 20; The thick positive cone of core of described cutter head 20 is 0.65:10 or 1.0:10.
In above-mentioned embodiment, when the described length of cutter head 20 and the ratio of diameter are less than or equal to 2.5:1, the thick positive cone of core of described cutter head 20 is 0.65:10; When the described length of cutter head 20 and the ratio of diameter are more than or equal to 2.5:1, the thick positive cone of core of described cutter head is 1.0:10.Setting like this, makes each reamer of multi-ladder contoured reamer of the present utility model have the thick intensity of enough cores, and holds bits chip space.
As shown in Figure 3, further, described second cutting edge 24 is the correction of R type, and described second cutting edge 24 cutting edge is through revising, and correction is 8 ° and 6 °.Setting like this, can improve the chip breaking ability of reamer of the present utility model.
In addition, due to shoulder hole and forming surface many, material difficulty processing.Reamer of the present utility model reduces groove anterior angle, to improve cutting edge roundness intensity.Particularly, described groove anterior angle is 3 ~ 5 °.
During reamer selection of the present utility model, the material of described multi-ladder contoured reamer is carbide alloy, and its model is ISO10 or ISO40.Particularly, should consider the hardness of material, intensity and grain size, wherein, must meet hardness >HRV1720, tensile strength is 3200N/mm
2.Bar grain size should be not more than 0.5-0.8 μm.
During manufacture, can manufacture on five axle CNC cutter and tool grinding machines.Particularly, emery wheel selects the R10 forming grinding wheel of custom-made to slot, and thick essence need be divided to put the first edge on a knife or a pair of scissors; Core is thick can be adjusted according to step diameter size; When reamer of the present utility model makes, reduce the groove anterior angle of the first cutting edge, improve cutting edge roundness intensity, to the second cutting edge cutting edge correction, to improve the chip breaking ability of cutter.
Below, test the performance of reamer of the present utility model, particularly, selection model is 45#, and hardness is HB160-180 steel.By measuring the cutting speed, the speed of mainshaft, feed speed, processing quantity, the stock-removing efficiency that add man-hour, contrast the performance of reamer of the present utility model and existing reamer.Test result is as shown in table 1 below:
Table 1
As shown in Table 1, the working (machining) efficiency of reamer of the present utility model, stock-removing efficiency are apparently higher than the many modes of drill bit being carried out process of existing employing.
To sum up, multi-ladder contoured reamer of the present utility model meets requirement that is many to the processing of the material of processing hydraulic valve body hole difficulty, ladder and the high life.Various structures drill bit is combined with corresponding shaping face by it, can the corresponding shoulder hole in the shaping place of time processing, working (machining) efficiency and machining accuracy high.
