Abstract
The present invention relates to a kind of secondary positioning numerical control processing technology of block mold runner.The secondary positioning mode of tool contact blade, solves the problem of the progress digital control processing of secondary positioning.The present invention has fundamentally reformed the manufacturing technology of the secondary positioning of block mold runner, is change in manufacture method substantially.Using the process of the present invention, backward traditional handicraft mode is instead of, percent defective is greatly reduced, reduce the production difficulty of block mold runner repairing type, secondary positioning precision is ensure that, and improves production efficiency, the product quality of block mold runner is improved.
Description
Technical field：
The present invention relates to a kind of secondary positioning numerical control processing technology of block mold runner.
Technical background：
For block mold runner, runner is revolving body, and blade is space curved surface, is used for without specific position secondary
Position repairing type.Centering positioning was carried out using root of blade cusp in the past, because the root of blade of model runner carried out burnishing part
Reason, blade cusp is bad to be determined；Top head is cone simultaneously, and when carrying out centering positioning, top and upper crown has
Interference, also results in positioning inaccurate.In the case where positioning centering is inaccurate, repairing type digital control processing, meeting are carried out to blade
Make blade profile not fairing, surface quality is poor, over-cutting occurs in cutter, influence product quality, overall mould can be directly resulted in
Type runner is scrapped.
The content of the invention：
The present invention provides a kind of brand-new, rational, perfect secondary positioning numerical control processing technology side of block mold runner
Method.The difficulty of the secondary positioning of block mold runner is reduced, the product quality of block mold runner is improved, reduces waste product
Rate.The technical scheme is that：
1) the maximum boundary line of intermediate blade (1) is extracted from model and is projected, maximum boundary projection line (2) is obtained；
2) draw identical with cutter (3) diameter circle (4), it is desirable to which circle (4) and maximum boundary projection line (2) are tangent, justify (4) with it is whole
The line of body Model runner (5) centre of gyration is 0 degree of line, calculates circle (4) central coordinate of circle value now；
3) block mold runner (5) is loaded on platen (6) centre of gyration, cutter (3) is moved to circle (4)
At central coordinate of circle position, platen (6) is rotated, when intermediate blade (1) contacts cutter (3), the lathe that stops operating work
Platform (6), now the position of block mold runner (5) is 0 degree of position of digital control processing.
Technique effect：
The present invention has fundamentally reformed the manufacturing technology of the secondary positioning of block mold runner, be in manufacture method substantially
Change.Using the process of the present invention, centering positioning is carried out compared to using root of blade cusp, waste product is greatly reduced
Rate, reduces the production difficulty of block mold runner repairing type, it is ensured that secondary positioning precision, and improves production efficiency, carries
The product quality of block mold runner is risen.
The present invention has been applied successfully in the production of Argentine President's dam block mold runner, and exploration has been formulated a set of brand-new
Secondary positioning numerical control processing process.
Brief description of the drawings：
Fig. 1 is the schematic diagram of the secondary positioning of block mold runner.
Fig. 2 is circle and the tangent schematic diagram of maximum boundary projection line.
In accompanying drawing：
1 intermediate blade；2 maximum boundary projection lines；
3 cutters；4 circles；
5 block mold runners；6 platens；
Embodiment：
As shown in Figure 1-2, the present invention provides a kind of brand-new, rational, perfect secondary positioning number of block mold runner
Control processing technology.The difficulty of the secondary positioning of block mold runner is reduced, the product quality of block mold runner is improved,
Reduce percent defective.Specific embodiments of the present invention are：
1) the maximum boundary line of intermediate blade 1 is extracted from model and is projected, maximum boundary projection line 2 is obtained；
2) circle 4 identical with the diameter of cutter 3 is drawn, it is desirable to which circle 4 is tangent with maximum boundary projection line 2, circle 4 and block mold runner
The line of 5 centres of gyration is 0 degree of line, calculates the central coordinate of circle value of circle 4 now；
3) block mold runner 5 is loaded on the centre of gyration of platen 6, cutter 3 is moved to the central coordinate of circle of circle 4
It is worth at position, rotates platen 6, when intermediate blade 1 contacts cutter 3, stops operating platen 6, now overall
The position of model runner 5 is 0 degree of position of digital control processing.
Claims (1)
1. a kind of secondary positioning numerical control processing technology of block mold runner, it is characterised in that comprise the following steps：
1) the maximum boundary line of intermediate blade (1) is extracted from model and is projected, maximum boundary projection line (2) is obtained；
2) circle (4) identical with cutter (3) diameter is drawn, it is desirable to which circle (4) and maximum boundary projection line (2) are tangent, circle (4) and overall mould
The line of type runner (5) centre of gyration is 0 degree of line, calculates circle (4) central coordinate of circle value now；
3) block mold runner (5) is loaded on platen (6) centre of gyration, cutter (3) is moved to the center of circle of circle (4)
At coordinate value position, platen (6) is rotated, when intermediate blade (1) contacts cutter (3), stop operating platen
(6), now the position of block mold runner (5) is 0 degree of position of digital control processing.
