Clamp in the numerical control cutting technology plays the role of play an important role in the machining
process, especially in the precision machining industry, it can not only help to operators quickly clamping workpiece, reduce the repetition labor workers, but also can improve the precision of the workpiece positioning.
Fixture industry in China after decades of construction and development, has initially formed relatively complete product categories, has a certain scale of production and the development ability of industry system.
But as the basis of nc cutting technology, fixture is far from universal in China, most of the mold enterprises still stays in the hand tools, manual correction table clamp workpiece, the stages, the manual process to a great extent, restricts the development of the mould industry.
How to reasonably use develop some jig, replacing more complex and repetitive work, become the urgent topic mould industry.
Ordinary electrode process, the principle of electro discharge machining, is widely used in the mold industry, at the same time solve the machining of high hardness and difficult questions.
The current domestic many mold factory in operation in the process of the electrode, still stay in the stage of manual operation, not much improvement.
Its process is first to use the blank material clamping screws to copper electrode on the workbench face of machining center, then the blank of the copper electrode material for timing, points, the knife, etc. , in the processing of the former process is completed, to the electrode machining, the electrode on the machining center processing is completed, the operator must be careful to copper electrode removed from the processing center of the workbench fixture, back to sparks machine play, play also need before the spark in the spark machine correction table, such as points, the height of several processes.
These processes depend entirely on the production workers in the process of operation manual operation way, make its efficiency and precision.
It is very tedious and repetitive work.
These process each link require very accurate, but not for prevention measures.
And because the operation staff quality the good and bad are intermingled, also directly affect the machining quality of workpiece.
Is different with ordinary electrode design method of 3 r electrode has its particular, the fixture has the very high accuracy, so there is no need to on the 3 r electrode processing reference edge and datum.
In this way, the 3 r electrode can save a lot of materials and processing time.
But the 3 r electrodes fixture should have many different shapes and specifications may be different from the clamping electrode, so in the design of 3 r electrode, must be considered according to the actual shape of the electrode, with 3 r in the position of the cavity, and electrodes fixture cooperate relationship, to determine a more reasonable way of clamping.
