The processing method that the purpose of this invention is to provide the large memorial archway plum blossom-shaped of a kind of Sendzimir multi-roll mill through hole, solved in the prior art, plum blossom-shaped through hole in the large memorial archway of Sendzimir multi-roll mill is being added man-hour, processing time consuming effort, the problem that precision is difficult to guarantee.
The technical solution adopted in the present invention is: the processing method of the large memorial archway plum blossom-shaped of a kind of Sendzimir multi-roll mill through hole, implement according to following steps:
4.1) with universal angular milling head trial cut toolsetting hole on frock toolsetting plate, adjust cutter;
4.2) with the datum hole tool setting of universal angular milling head on the frock datum plate, use the dial test indicator centering, make the datum hole center superposition on the universal angular milling head cutter centre of gyration and the frock datum plate;
4.3) alter coordinate, process first semi arch:
Alter coordinate by what record in the above-mentioned steps 3 apart from size, the universal angular milling head cutter centre of gyration is fixed on first semi arch center, a bit of semi arch of trial cut on the frock header board;
Withdraw from cutter, with the distance between a bit of semi arch center of trial cut on datum hole and the frock header board on the lever meter detection frock datum plate, whether with above-mentioned steps 3 in record apart from consistent size, if inconsistent, then adjust universal angular milling head cutter centre of gyration position;
Trial cut is played table and is detected for the second time; Detect institute's recording distance consistent size in numerical value and the above-mentioned steps 3 until play table, this moment, universal angular milling head cutter centre of gyration position was the exact position at first semi arch center, and after adjusting, first semi arch of borer spare closes figure;
4.4) allowing blade replacement, universal angular milling head is removed angle, by above-mentioned steps 4.1), step 4.2), step 4.3) process successively all the other each semi arches.
The invention has the beneficial effects as follows that simple in structure, easy to operate, cost is low, effectively guaranteed machining accuracy.

The specific embodiment
With reference to Fig. 1, Fig. 2, be schematic cross-section and the perspective view of the inventive method plum blossom-shaped through hole to be processed.
The enforcement of the inventive method depends on frock header board 2, frock datum plate 3 and frock toolsetting plate 4.
With reference to Fig. 3, offer plum blossom-shaped through hole trial cut hole 8 on the frock header board 2.
With reference to Fig. 4, offer datum hole 6 on the frock datum plate 3.
With reference to Fig. 5, offer toolsetting hole 7 on the frock toolsetting plate 4.
With reference to Fig. 6, the processing method of the large memorial archway plum blossom-shaped of Sendzimir multi-roll mill of the present invention through hole, specifically implement according to following steps:
With reference to Fig. 3, convenient for following process, on frock header board 2, in eight semi arch holes, process a undercut every 10mm, the dark 1mm of each undercut, wide 5mm notice that the undercut relative position is basically identical in each semi arch hole, are convenient to follow-up measurement;
Coordinate by shown in Figure 6, is altered in step 3, the center of pressing fixed workpiece 1, at frock datum plate 3 main shaft bore hole, and machining benchmark hole 6, the roughness of datum hole 6 reaches Ra3.2; The center of datum hole 6 and the distance at half and half circular hole center in the plum blossom-shaped through hole trial cut hole 8 on the record frock datum plate 3 are as the foundation of postorder processing;
4.1) with universal angular milling head trial cut toolsetting hole 7 on frock toolsetting plate 4, accurately adjust cutter, make the tolerance of universal angular milling head in the toolsetting hole 7 of frock toolsetting plate 4 processing be 0 ~+0.01mm;
4.2) with datum hole 6 tool settings of universal angular milling head on frock datum plate 3, use the dial test indicator centering, make datum hole 6 center superpositions on the universal angular milling head cutter centre of gyration and the frock datum plate 3, axiality is less than 0.0025;
4.3) alter coordinate, processing semi arch A(is first semi arch among Fig. 1): alter coordinate by what record in the above-mentioned steps 3 apart from size, the universal angular milling head cutter centre of gyration is fixed on semi arch A center, a bit of semi arch of trial cut on frock header board 2; Withdraw from cutter, with the distance between a bit of semi arch center of trial cut on datum hole 6 and the frock header board 2 on the lever meter detection frock datum plate 3, whether with above-mentioned steps 3 in record apart from consistent size, if inconsistent, then adjust universal angular milling head cutter centre of gyration position; Trial cut is played table and is detected for the second time; Detect institute's recording distance consistent size in numerical value and the above-mentioned steps 3 until play table, this moment, universal angular milling head cutter centre of gyration position was the exact position at semi arch A center, and after adjusting, borer spare semi arch A closes figure;
4.4) allowing blade replacement, universal angular milling head is removed angle, by above-mentioned steps 4.1), step 4.2), step 4.3) process successively all the other each semi arches.
The problem that should note in the inventive method critical process:
1) in order to satisfy drawing requirement, must adjust equipment precision before the fine finishining.
2) semi arch hole of every processing, main shaft returns datum mark, more renews blade, again alters coordinate, begins to process next semi arch hole again, can eliminate machine tool gap like this, reduces the tool wear error.
3) during semifinishing plum blossom-shaped through hole, should guarantee the uniformity of semi arch hole allowance as far as possible, preferably be controlled in 0.10 ~ 0.12 scope that roughness is controlled at Ra3.2 ~ 1.6; During fine finishining plum blossom-shaped through hole, guarantee the uniformity of cutting parameter.
In sum, the processing method of the large memorial archway plum blossom-shaped of Sendzimir multi-roll mill of the present invention through hole, use the frocks such as a frock header board, frock datum plate, frock toolsetting plate, adopt the HCW3-260 boring machine, utilize ram and universal angular milling head, ram intensity is good, solved boring bar stretch out longer, the problem that amount of deflection is inadequate; Because the plum blossom hole size is little, plum blossom hole of every processing, universal angular milling head need be moved corresponding angle, has well solved the again problem of centering.Facts have proved, adopt the memorial archway of the inventive method processing to satisfy drawing fully and check the outline requirement, provide new method for processing this type of part.
