Abstract
The utility model relates to a combined tool for machining, in particular to a polycrystalline diamond combined tool for carbon electrode excircle machining, which comprises a tool bar, bolts and blade clamping pieces and is characterized in that two tool holders are transversely arranged at the front part in parallel; a rough turning tool blade and a fine turning tool blade are arranged in the vertical direction; the blades are pressed on the tool bar by the blade clamping pieces; the tip of the rough turning tool blade is 0.7-0.9 mm higher than that of the fine turning tool blade in the vertical direction of the tool bar, and the horizontal distance between the two tools is 40 mm; and the tip of the rough turning tool blade is 3-5 mm shorter than that of the fine turning tool blade in the longitudinal direction of the tool bar. The polycrystalline diamond combined tool has the advantages that the effect of finishing excircle machining through one pass can be realized by adopting the combined tool, the precision requirements are satisfied, a tool rest is simplified, the production efficiency is improved by double times under the condition that the process cost is not increased, the tool replacement is not required, and excircle coarse machining and excircle fine machining are finished through one pass.
Description
Technical field
The gang tool of the related a kind of machining of the utility model.
Background technology
At present, be used to refine the large cylindrical electrode that silicon is produced, diameter 800-1500mm, length 2200-3500mm, its cylindrical atomization degree and machining accuracy with machining accuracy that influences subsequent processing and end product quality, directly influences the cost and the quality of matallurgical products.The special purpose lathe of being furnished with the multistation knife rest is adopted in technology behavior of the same trade, adopts hard alloy cutter; Manually processing, earlier rough turn, surface roughness reaches 12.5 microns; Capable again knife rest transposition, tool changing tool, capable again finish turning; Surface roughness just can reach the 3.2-1.6 micron, and there is following defective in this processing method:
(1) multistation knife rest cost is high, has position error.
(2) twice processing, tool changing is long man-hour, and efficient is low.
(3) need to be equipped with two kinds of cutters, operating cost is high.
(4) the hard alloy cutter durability is poor, and a blade is processed an electrode at most, has just scrapped, and can't realize automation processing.
Summary of the invention
The purpose of the utility model is to overcome the prior art deficiency, and a kind of roughing and accurately machined polycrystalline diamond gang tool are provided.
A kind of polycrystalline diamond gang tool that is used for the processing of carbon electrode cylindrical comprises knife bar, screw, blade folder, it is characterized in that; Front cross is provided with two tool rests side by side; In the vertical direction is provided with rough turn blade and finish turning blade, the blade folder with blade pressing on knife bar; On the knife bar vertical direction, rough turn insert tip is than the high 0.7-0.9mm of finish turning insert tip, two point of a knife horizontal range 40mm; On knife bar was vertical, rough turn insert tip was than the short 3-5mm of finish turning insert tip; Roughing tool main cutting edge length 25-30mm, roughing tool chisel edge length 2-5mm; Finishing tool main cutting edge length 20-25mm, finishing tool chisel edge length 12-16mm.Said rough turn blade (4) and finish turning blade (10) material are polycrystalline diamond.
The advantage of the utility model adopts gang tool, can realize, one-pass is accomplished cylindrical processing; Precision meets the demands, and has simplified knife rest, under the condition that the technology cost does not increase; Improve twice production efficiency, need not tool changing, one-pass is accomplished cylindrical roughing and fine finishining.
Description of drawings
Fig. 1 is the utility model structural representation.
Knife bar 1, screw 2, blade folder 3, rough turn blade 4, roughing tool main cutting edge 5, roughing tool chisel edge 6, finishing tool main cutting edge 7, finishing tool chisel edge 8, tool rest 9, finish turning blade 10 are arranged among the figure.
The specific embodiment
Below in conjunction with accompanying drawing and instantiation the utility model is made detailed description further.
Fig. 1 is the utility model structural representation, and this polycrystalline diamond gang tool, knife bar 1 are seized on both sides by the arms on the tool holder of being expert at, and screw 2, blade folder 3 are used for fixing rough turn blade 4 and finish turning blade 10; End at knife bar 1 laterally is provided with two tool rests 9 side by side, and rough turn blade 4 and finish turning blade 10 are set respectively on the tool rest 9; On knife bar 1 vertical direction, rough turn blade 4 tips are than finish turning blade 10 most advanced and sophisticated high 0.7-0.9mm, two point of a knife horizontal range 40mm, knife bar 1 vertically on, rough turn blade 4 tips are than finish turning blade 10 most advanced and sophisticated short 3-5mm; Roughing tool main cutting edge 5 length 25-30mm, roughing tool chisel edge 6 length 2-5mm; Finishing tool main cutting edge 7 length 20-25mm, finishing tool chisel edge 8 length 12-16mm.
Turning adds man-hour, and rough turn blade 4 first finished surfaces carry out the roughing of full depth amount, and the finish turning blade 10 thereafter, to finished surface just, carries out little bite fine finishining, has both guaranteed surface quality, has improved working (machining) efficiency again.
Claims (2)
