Roller is transferred to aligning mould type groove center;
The knife bar pole stock of needs processing is placed in the mould type groove, and the degree of depth of control feed is according to the common method of operating press process drilling rod chip area of planer;
With the Quenching Treatment of routine, be HRC38~43;
Blow sand, alignment, promptly get required process the solid boring bar chip area.
The specific purpose tool that is used for the inventive method is made of following two parts:
A. mould: clamp body is that the clamp body body that has arc groove that two inboard end faces are oppositely arranged is formed, and the relative arc groove of two clamp body bodies is spliced to form semicircle groove, and the arranged outside of clamp body body has 3~5 bolts hole;
B. suppress roller: the below of cutter hub is provided with the opening that the compacting roller is installed, and the compacting roller is placed in the opening, is connected with cutter hub by connecting axle, and is gapped between roller and the cutter hub.
Owing to adopt technique scheme, adopt specific purpose tool of the present invention, on common planer, adopt conventional planer processing method, promptly can process the ultralong deep hole drilling rod that meets technological requirement, so processing method is simple, simultaneously owing on common planer, promptly can process out the ultralong deep hole drilling rod that meets technological requirement, do not need specialized apparatus, therefore also have the low advantage of processing cost.
Specific purpose tool of the present invention adopts conventional accessory preparation, so low cost of manufacture, because this specific purpose tool is the requirement preparation according to the inventive method, therefore can guarantee that ultralong deep hole bores the requirement of technical indicators such as the intensity of knife bar, straight degree, logical oil, the unobstructed property of chip removal, difficulty of processing and processing cost have been reduced, improve production efficiency, can guarantee the machining accuracy of processing small batch deep hole drill knife bar.
Description of drawings
Fig. 1 is the structure diagram of an embodiment of the present invention;
Fig. 2 is the structural representation of deep hole drill knife bar cross section.
Among the figure, 1 is the clamp body body, and 2 is fastening bolt, and 3 is connecting axle, and 4 is roller, and 5 is cutter hub, and 6 is oil through, and 7 is chip area, and 8 is groove, and 9 is knife bar.
The specific embodiment
Referring to Fig. 1, according to the diameter and the requirement of the chip area degree of depth of deep hole drill knife bar, preparation is used for specific purpose tool of the present invention, and its specific purpose tool is made up of mould and compacting roller:
1. mould.Clamp body is that the clamp body body that has arc groove 1 that two medial surfaces are oppositely arranged is formed, the arranged outside of clamp body body has 3~5 bolts hole, the corresponding screw of two clamp body bodies is communicated with, alignment pin is placed in the hole, with bolt 2 two clamp body bodies are connected to form semicircle groove 8, the radius that two clamp body bodies are spliced to form semicircle groove equals the diameter of knife bar 9, be used to lay processed knife bar tubing, and in order to guaranteeing to add the machining center in man-hour, the control machining tolerance is within ± 0.05mm.
2. compacting roller.The below of cutter hub is provided with the opening that the compacting roller is installed, and compacting roller 4 is placed in the opening, is connected with cutter hub 5 by connecting axle 3, and is gapped between roller and the cutter hub.The working face of compacting roller (binding face when being roller compacting workpiece) should uniform and smooth (more than the roughness Ra0.8) when making, and does not have the processing lines with the deep hole drill knife bar chip area surface that guarantees to process.
The preparation process of deep hole drill knife bar is as follows:
Whether get the deep hole drill knife bar material that meets technological requirement, measure the material endoporus and meet the requirements, whether cylindrical has allowance, allowance is 1~1.5mm;
Intercepting deep hole drill knife bar material according to technological requirement, is put about size 10mm surplus at length direction and to be blocked, and is used for removing in pressing process at the workpiece head because of the distortion of the generation that is hit or break.Check alignment with flat board, after the alignment linearity tolerance be controlled at<0.02/100mm in;
After the alignment, to the technological requirement size, its cylindrical processing dimension should be by the lower deviation dimensioned of technological requirement tolerance dimension with centreless grinding grinding cylindrical, and size can be controlled in the margin of tolerance after workpiece expanded during with assurance press type groove, and concrete grammar is as follows:
