Abstract
The invention relates to a numerical control machining method of a bending pipe die free of benchmark. The numerical control machining method comprises step 1, adding added cuboid block structures at the beginning of blank customizing; step 2, achieving that two positioning surfaces of added cuboid blocks are parallel through planning and grinding processes; step 3, simultaneously installing and clamping the added cuboid blocks on a numerical control machine tool; step 4, performing twice layered rough machining on the right side of the bending pipe die; step 5, performing twice layered semi-finish machining on the right side of the bending pipe die; step 6, performing twice layered finish machining on the right side of the bending pipe die; step 7, turning over the machined bending pipe die, repeating the step 4 to the step 6 after the added cuboid blocks are positioned and achieving shape machining of the bending pipe die; and step 8, cutting and removing the added cuboid blocks through lines according to the drawing size, polishing a molded surface by a bench worker and achieving the integral bending pipe die. According to the numerical control machining method of the bending pipe die free of benchmark, the problem of out-of-tolerance of the bending pipe die free of benchmark is effectively solved, a reasonable method of numerical control machining on the integral tools is provided, the machining precision of the integral tools can be high, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of no benchmark Tube Bending Die Drawing numerical-control processing method, problem that can't clamping when be used for solving the Tube Bending Die Drawing digital control processing.
Background technology
As shown in Figure 1, the design feature of Tube Bending Die Drawing is to be round around the profile, except two ends is to face directly, all the other are curved surface, need turn-over processing in process, machining benchmark is difficult to determine, particularly in the process of turn-over digital control processing, because of the processing characteristics of cutting force, cutting output, cutting speed, clamping and lathe itself, these factors can cause frock distortion, misrun and scrap.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of no benchmark Tube Bending Die Drawing numerical-control processing method, this method has not only effectively solved the overproof problem of no benchmark Tube Bending Die Drawing, also the digital control processing to whole frock has proposed more reasonable method, make the machining accuracy height of whole frock, and it has improved production efficiency.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of no benchmark Tube Bending Die Drawing numerical-control processing method may further comprise the steps:
1) at the woollen initial stage of customization, increase woollen size, be considered as setting up at the two ends of Tube Bending Die Drawing the block structure of adding of cuboid, and design is added in the piece along the distance L=roughing tool radius+5～10mm to mould tire edge line;
2) by dig, the grinder order reaches that to add piece two locating surfaces parallel;
3) will add two locating piece horizontal positioned of piece, and simultaneously clamping on Digit Control Machine Tool;
4) two secondary clearing roughing are carried out in the front of Tube Bending Die Drawing, made allowance 2mm for the first time, made allowance 1mm for the second time, the restraining line of roughing tool processing apart from add edge in the piece apart from B1=roughing tool radius+1mm;
5) two secondary clearing semifinishings are carried out in the front of Tube Bending Die Drawing, the restraining line of semifinishing cutter processing apart from add edge in the piece apart from B2=semifinishing tool radius+2mm;
6) two secondary clearing fine finishining are carried out in the front of Tube Bending Die Drawing, the restraining line of finishing tool processing apart from add edge in the piece apart from B3=finishing tool radius+3mm;
7) with the Tube Bending Die Drawing turn-over that processes, add piece location after, repeat 4～6 steps, and finish the sharp processing of Tube Bending Die Drawing;
8) according to the figure paper size, will add piece and excise with the line cutting, pincers worker polishing profile, whole Tube Bending Die Drawing is finished.
This no benchmark Tube Bending Die Drawing numerical-control processing method adopts above-mentioned steps, add the technical scheme of piece by increase, reduced the clamping difficulty of Tube Bending Die Drawing, simultaneously in roughing, semifinishing and fine finishining process, reduced the operation at clear angle by the division of restraining line, simplify process, reduced the generation of accumulated tolerance.

2) by dig, the grinder order reaches that to add piece two locating surfaces parallel;
3) will add two locating piece horizontal positioned of piece, and simultaneously clamping on Digit Control Machine Tool;
4) two secondary clearing roughing are carried out in the front of Tube Bending Die Drawing, made allowance 2mm for the first time, made allowance 1mm for the second time, the restraining line of roughing tool processing apart from add edge in the piece apart from B1=3.5mm+1mm=4.5mm;
5) two secondary clearing semifinishings are carried out in the front of Tube Bending Die Drawing, the restraining line of semifinishing cutter processing apart from add edge in the piece apart from B2=10mm+2mm=12mm.
