Abstract
The invention relates to a technique for preventing deformation after mold machining with a large removal quantity. The technique comprises the following steps that (1) a mold blank of a cuboid structure is positioned on a planing machine, and grinding is conducted on a grinding machine till the upper surface and the lower surface are parallel; (2) an upper curved surface is machined roughly, 10 mm allowance is reserved, and a simulation result data set of the molded surface with the 10 mm allowance is saved in a tool data set folder to serve as a blank data set for secondary rough machining; (3) a datum hole is machined after rough machining; (4) annealing heat treatment is conducted; (5) after annealing treatment, the bottom surface of the mold blank is machined through the planing machine till the bottom surface is planed flat; (6) rough machining is conducted again; (7) numerical-control semi-finish machining and finish machining are conducted, and finally the original datum hole is reamed and bored to serve as the measurement datum; and (8) the molded surface is polished by a bench worker, and machining is completed. According to the technique, a reasonable process sequence is adopted, and the problem that a mold deforms after being machined is solved.
Description
Technical field
The present invention relates to a kind of mould tire preventing removal amount big and add the process of post-construction deformation, belong to machining process.
Background technology
Some mould tire removal amount in the course of processing is big, and big removal amount causes producing a large amount of stress in the course of processing, although measuring qualified after processing, but after in processing, the stress of generation is released, mould fetalism face will deform upon, it is impossible to is continuing with.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of mould tire preventing removal amount big and adds the process of post-construction deformation, and this process uses rational process sequence, solves a difficult problem for processing rear mold tire deformation.
For solving problem above, the concrete technical scheme of the invention is as follows: a kind of mould tire preventing removal amount big adds the process of post-construction deformation, comprises the following steps:
1) being positioned on planer by the mould fetal hair material of rectangular structure, processing mould fetal hair material upper and lower faces, to technological requirement size, is then ground to upper and lower surface parallel on grinding machine；
2) by the bottom surface clamping of mould tire on tool palette, and tool palette is positioned on numerically controlled machine, by the nc program processing mould tire of technics institution, roughing top-surface camber, stay the surplus of 10mm, and the Simulation result data collection that profile leaves 10mm surplus is saved in frock document data set folder, as secondary rough machined woollen data set；
3) reference holes after roughing；
4) the mould tire after roughing is carried out heat treatment of annealing, remove the stress produced in processing；
5) after annealing, planer processing mould tire bottom surface, planish；
6) continue to be placed in Numerically controlled machine mould tire, by former datum hole centering, location, use secondary rough machined woollen data set to carry out roughing again；
7) after roughing, then carry out numerical control semifinishing and polish, finally expand the former datum hole of boring, as measuring basis；
8) after measurement profile is qualified, pincers worker polishing profile, completion of processing.
This mould tire preventing removal amount big adds the process of post-construction deformation and uses first digital control processing, is removing mould tire internal stress, in the method continuing employing digital control processing, solves a difficult problem for processing rear mold tire deformation.

2) by the bottom surface clamping of mould tire on tool palette, and tool palette is positioned on numerically controlled machine, by the nc program processing mould tire of technics institution, roughing top-surface camber, stay the surplus of 10mm, and the Simulation result data collection that profile leaves 10mm surplus is saved in frock document data set folder, as secondary rough machined woollen data set；
3) reference holes after roughing；
4) the mould tire after roughing is carried out heat treatment of annealing, remove the stress produced in processing；
5) after annealing, planer processing mould tire bottom surface, planish；
6) continue to be placed in Numerically controlled machine mould tire, by former datum hole centering, location, use secondary rough machined woollen data set to carry out roughing again；
7) after roughing, then carry out numerical control semifinishing and polish, finally expand the former datum hole of boring, as measuring basis；
8) after measurement profile is qualified, pincers worker polishing profile, completion of processing.
