Abstract
The utility model discloses a special reamer for PCD (poly crystal diamond). The special reamer comprises a reamer bar and a reamer body, wherein the reamer bar is in a telescopic shape, an annular bulge is arranged on the reamer bar, an annular clamp groove is formed in the annular bulge, the reamer bar and the reamer body are integrally formed, the middle part of the reamer body is provided with a reamer blade a used for hole and opening chamfering, one end, far away from the reamer bar, of the reamer body is provided with a reamer blade b used for reaming, and two reamers are arranged at the reamer point part of the reamer body. Compared with the existing reamer, the special reamer has the advantages that the intensity of the reamer is enhanced through reducing the length of the reamer bar, increasing the diameter of the reamer bar and adopting hard alloy materials for making the reamer bar, the reamer blades are made of diamond materials, the abrasion resistance degree of the reamer is improved, the special reamer is applicable to the existing mass production, the production efficiency is improved, the production cost is reduced, the process production capacity is improved, and the product quality is ensured.
Description
Technical field
The utility model relates to a kind of process tool, relates in particular to the special-purpose reamer of a kind of PCD.
Background technology
Current existing aperture processing mode adopts fraising or bore hole to complete conventionally, and its process velocity cannot promote, and roughness is wayward, can not adopt high rotating speed, and aperture size changes greatly, and production efficiency is low.Due to machinery industry develop rapidly now, all adopt mass production method, existing processing mode, cannot meet high production efficiency, and process production capacity is low, cannot guarantee product quality.
Utility model content
The problem existing for above-mentioned prior art, the utility model object is to provide a kind of special-purpose reamer of PCD that has solved above problem.
The technical solution of the utility model is: the special-purpose reamer of a kind of PCD, comprise knife bar and cutter hub, described knife bar is convergent-divergent shape, described knife bar is provided with annular projection, on described annular projection, offer annular slot, described knife bar and cutter hub are one-body molded, and described cutter hub middle part is provided with the blade a to orifice chamfer, described cutter hub is provided with carrying out the blade b of fraising away from knife bar one end, and the point of a knife place of described cutter hub is provided with two-edged reamer;
As preferably, described knife bar and cutter hub Length Ratio are 2:1;
As preferably, described blade a and blade b adopt diamond to make;
As preferably, described blade a, blade b, two-edged reamer are fixedly connected with cutter hub respectively;
As preferably, described cutter hub and knife bar adopt Hardmetal materials to make.
The beneficial effects of the utility model are: the utility model is by shortening knife bar length, increase knife bar diameter, knife bar employing Hardmetal materials, increase the intensity of cutter, blade adopts diamond, improve the abrasion resistance of cutter, adapt to now and produce in enormous quantities, enhance productivity, reduce production costs, raising process production capacity, has guaranteed product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1. knife bar; 2. cutter hub; 3. blade a; 4. blade b; 5. two-edged reamer; 6. annular projection.
The specific embodiment
Embodiment: as a kind of embodiment of the present utility model, the special-purpose reamer of a kind of PCD as shown in Figure 1, comprise knife bar 1 and cutter hub 2, described knife bar 1 is convergent-divergent shape, described knife bar 1 is 2:1 with cutter hub 2 Length Ratios, by shortening knife bar 1 length, increase knife bar 1 diameter, increase the intensity of cutter, reply High Rotation Speed, described knife bar 1 is provided with annular projection 6, on described annular projection 6, offer annular slot, convenient and hold assembly is fastenedly connected, described knife bar 1 is one-body molded with cutter hub 2, described cutter hub 2 adopts Hardmetal materials to make with knife bar 1, increase the intensity of cutter, described cutter hub 2 middle parts are provided with the blade a3 to orifice chamfer, described cutter hub 2 is provided with carrying out the blade b4 of fraising away from knife bar 1 one end, described blade a3 and blade b4 adopt diamond to make, improve the abrasion resistance of cutter, the point of a knife place of described cutter hub 2 is provided with two-edged reamer 5, described blade a3, blade b4, two-edged reamer 5 is fixedly connected with cutter hub 2 respectively.
Instantiation,
The utility model, because strengthened the intensity of cutter, can improve cutter and adopt higher rotating speed when cutting, adopts the amount of feeding faster; After use, roughness is significantly improved and stablizes, dimensionally stable, and production efficiency increases, and cutter consumes cost per unit to be reduced, and product machine adds cost.
Bore hole cutting parameter: rotating speed: 2000～3000 revs/min, the amount of feeding: 200～300mm/mi;
Given parameters rotating speed: 6000 revs/min, the amount of feeding: 800mm/min;
The result: roughness: Ra0.4,10000 logical only passed examinations of aperture size 100%, aperture size detects and reduces 0.002mm than original state.
By above improvement, greatly strengthened the intensity of cutter, solved the problem that aperture processing mode exists, make roughness easy to control, can adopt high rotating speed, adapt to now and produce in enormous quantities, enhance productivity, reduce production costs, improve process production capacity, guaranteed product quality.
