Abstract
The invention discloses a method for processing moulds with precise and tiny characteristics by using high speed mills, comprising the following steps of: processing a blank, calibrating a clamp, clamping the blank, rough processing, vacuum heat treating, trimming appearance, finishing, detecting and postorder processing. In the invention, the equipment of a high speed milling center can carry outthe finishing on the mould, however, the equipment cannot be applied to the processing of the mould with precise and tiny characteristics. Therefore, the high speed mill can directly process a produc t area on a mould part by utilizing the method. The method has short processing cycle, little processing difficulty, favorable workpiece surface and cost reduction, can never have the condition of oblique, and has risks far below the traditional discharge processing.
Description
Technical field
The present invention relates to the Mould Machining field, specifically relate to a kind of high-speed milling that utilizes having the die processing method of precise and tiny characteristics.
Background technology
In the connector process of exploitation, because the particularity of product requirement and structure concerning present mold machining technology, is a great challenge such as the mainframe computer central processing unit.Hole in irregular shape is arranged on the product, and the dimensional requirement in these holes is very high, neither square, neither be circular, fillet is promptly arranged, wedge angle is also arranged, different directions is also gradient.Traditional grinding machine can't be processed, and can use spark machined in theory, but difficulty of processing is high, and electrode difficulty of processing height, cost height, cycle are long.There is trickle pit on the surface of spark machined, and is easy to produce oblique.The demoulding be can have a strong impact on for this series products, thereby flatness, physical dimension of product etc. influenced.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of high-speed milling that utilizes having the die processing method of precise and tiny characteristics.
Purpose of the present invention is achieved through the following technical solutions: utilize high-speed milling to having the die processing method of precise and tiny characteristics, may further comprise the steps:
1.. machining blanks: be processed into blank with the steel of not doing Quenching Treatment, each monolateral surplus of staying 0.2～0.25mm of blank, the mutual perpendicularity that blank is six is controlled in the 0.01mm;
2.. the anchor clamps calibration: the groove of clamping blank on the anchor clamps is processed two datum levels, and wherein the datum level on the vertical direction keeps vertical with base, and the flatness between datum level on the horizontal direction and the base horizontal plane is controlled in the scope of 0.002mm;
3.. the blank clamping: blank is clamped in the anchor clamps, and fastening by pad and screw, then with the depth of parallelism and the perpendicularity of amesdial detection blank and anchor clamps, guarantee that the depth of parallelism and perpendicularity are controlled in the scope of 0.01mm;
4.. roughing: the anchor clamps of the good blank of clamping are placed on the base, determine the initial manufacture position, and set cutter, move high-accuracy high-speed machining center and begin to carry out the roughing program, when carrying out, its roughing program moves: at first select for use the cutter of Ф 1mm that surplus is removed in 1 processing district of the Ф on the blank according to following step, next is to select for use the cutter of Ф 0.6mm that surplus is removed in 0.6 processing district of the Ф on the blank, be to select for use the cutter of Ф 0.3mm that surplus is removed in 0.3 processing district of the Ф on the blank at last, make half-finished workpiece;
5.. vacuum heat: during the roughing of blank process, it is less that surplus is stayed, and in order to guarantee fine finishining enough surpluses can be arranged, and must carry out conventional vacuum heat and three temper, through promptly obtaining the workpiece at initial stage after the vacuum heat;
6.. contouring: have a small amount of distortion through the workpiece after the step vacuum heat 5., need repair profile this moment, and mutual perpendicularity, the depth of parallelism with six of blanks during finishing control in the 0.002mm;
7.. fine finishining: workpiece is put on the anchor clamps once more, and by adjusting, the depth of parallelism, perpendicularity that make the datum level of workpiece and anchor clamps are in 0.003mm; Put it on the base again, determine accurately machined initial position, if good cutter, move high-accuracy high-speed machining center and begin to carry out the fine finishining program, when carrying out, its fine finishining program moves: select for use the cutter of Ф 1mm that standard is milled in the bottom surface of workpiece upper end earlier according to following step, cutter with Ф 0.6mm mills standard with bottom surface local Ф 1mm cutter milling less than the place again, joins until the face with the milling of Ф 1mm cutter; The cutter of selecting Ф 0.3mm at last for use is with side, the whole millings in bottom surface one time, to guarantee the flatness of bottom surface;
8.. detect: after fine finishining was intact, workpiece did not take off from anchor clamps earlier, has the anchor clamps of workpiece to take off from base clamping, detects shape with projector, after qualified, again workpiece is taken off, if defective, continue to put back on the base, workpiece is continued finishing, till qualified.
9.. postorder processing: after the tiny boss of head processes, grab the position of accuracy portion small boss, processing remainder according to the manufacturing procedure of conventional grinding machine.
How many sizes of described blank decides according to workpiece quantity, and its blank size computing formula is: blank size=(workpiece size+section distance) * workpiece quantity-section distance, the length of blank should not be long, is controlled between 50mm～60mm to get final product.
Use the cutter of Ф 1mm that 1 processing district of the Ф on blank removal margin value is 0.01mm in the described roughing step, Φ 0.6 processing district and φ 0.3 processing district all are the side edge with Φ 1 processing district, after the cutter milling through Φ 0.3mm, side surface of workpiece is only stayed the 0.02mm surplus, and the bottom surface has only the 0.01mm surplus.
In the described fine finishining step, note the problem of tool wear, whenever process once, detect have above half the wearing and tearing of workpiece tolerance just to renew cutter processing to cutter.
Though the equipment at high-speed milling center can carry out fine finishining to mould among the present invention, the mould that can not be applied to have precise and tiny characteristics is processed.Therefore utilize method among the present invention by high-speed milling, can be with the method for the direct machine-shaping of product area on the mould parts.Its short process-cycle, and difficulty of processing is low, and surface of the work is good, and the situation that has inclination anything but takes place, and risk is well below traditional discharge processing, and cost also decreases.
