Abstract
The invention discloses a machining process for a sealing ring mold. In the machining course, firstly, a large cutter is adopted for rough machining a mold cavity; then a small cutter is selected and used, and a plurality of balances are cleared away through clearance angle machining to make the balances on a boss even; and finally a small cutter is selected and used, a best equal-height scheme is adopted for overall machining in place started from the middle, the bottom size is ensured, and cutter lapping defects are reduced; in addition, a torn edge groove is machined through a layering machining method, so that a machined single side of the torn edge groove is avoided, and the quality and precision of the torn edge groove are improved. The optimally designed machining process for the sealing ring mold is simple in process and reasonable in design. After overall machining is adopted for the boss at the bottom of the cavity, the cutter lapping defects in the cavity are lifted, so that sanding is convenient, and the work efficiency is improved. The machining precision of the mold is greatly improved, and scrapping of the mold is avoided.
Description
Technical field
The present invention relates to sealing ring technical field, particularly relate to a kind of sealing ring mould processing technology.
Background technology
Conventional seals ring mould processing technology, at processing upper and lower mould cavity bottom boss place, adopts much knives clear angle processing, is machined directly to and requires size.In reality processing, easily produce tool marks joint, and position is at cavity bottom, because such mold cavity bottom size is less, is not easy to sanding, causes product quality to decline.Reduce operating efficiency.During processing torn edges groove, many employings one are worked into the end cutter, not tool changing.Easily cause mould torn edges groove monolateral, dimension overproof, causes mould to scrap.
Summary of the invention
For solving the technical problem existed in background technology, the present invention proposes a kind of sealing ring mould processing technology.
A kind of sealing ring mould processing technology that the present invention proposes, comprises the following steps:
S1, mould stock to be processed to be positioned;
S2, select the first cutter to location after mould stock carry out die-cavity roughing, the pre-made allowance of cavity bottom boss;
S3, select the second cutter to carry out angle processing clearly to roughwrought mold cavity, even boss surplus, monolateral reserved predetermined surplus, wherein the size of the second cutter is less than the first cutter;
S4, the second cutter is selected to adopt the boss of best contour scheme to mold cavity process through S2 to process, removal surplus.
Preferably, in S4, the second cutter is selected to process die cavity boss from the middle part of die cavity.
Preferably, in S3, described predetermined surplus is 0.01 ~ 0.02mm; Preferably, described predetermined surplus is 0.015mm.
Preferably, also comprise the following steps: S5, select the 3rd cutter to adopt reference line processing method at die cavity periphery processing torn edges groove.
Preferably, in S5, the machining path direction of the 3rd cutter is climb cutting direction.
Preferably, in S5, when processing described torn edges groove, first roughing is carried out to the described torn edges groove first half, then roughing is carried out to described torn edges groove Lower Half, finally finish-milling processing is carried out to described torn edges groove.
Preferably, in S5, when carrying out roughing to described torn edges groove, described torn edges trench bottom reserves the second predetermined surplus.
Preferably, in S5, described second predetermined surplus is 0.15 ~ 0.025mm.
In the present invention, the sealing ring mould processing technology proposed, in process, first large cutter is adopted to carry out roughing to mold cavity, then props is selected to be removed by the processing of clear angle many places surplus, make surplus on boss even, little cutter is finally selected to adopt best contour scheme overall processing from middle part to put in place, ensure bottom size, reduce cutter lapping defect, in addition by the method processing torn edges groove that layering is processed, avoid torn edges slot machining monolateral, improve quality and the precision of torn edges groove.By the sealing ring mould processing technology of above-mentioned optimal design, technique is simple, reasonable in design, cavity bottom boss place makes in die cavity, cutter lapping defect to be lifted, is convenient to sanding after adopting overall processing, increase work efficiency, greatly improve the machining accuracy of mould, avoid mould to scrap.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of a kind of sealing ring mould processing technology that the present invention proposes.
Detailed description of the invention
As shown in Figure 1, Fig. 1 is the schematic flow sheet of a kind of sealing ring mould processing technology that the present invention proposes.
With reference to Fig. 1, a kind of sealing ring mould processing technology that the present invention proposes, comprises the following steps:
S1, mould stock to be processed to be positioned;
S2, select the first cutter to location after mould stock carry out die-cavity roughing, the pre-made allowance of cavity bottom boss;
S3, the second cutter is selected to carry out angle processing clearly to roughwrought mold cavity, even boss surplus, monolateral reserved predetermined surplus, wherein the size of the second cutter is less than the first cutter, described predetermined surplus is 0.01 ~ 0.02mm, and preferably, described predetermined surplus is 0.015mm;
S4, select second cutter adopt best contour scheme from the middle part of die cavity, mold cavity boss process through S2 is processed, removal surplus;
S5, the 3rd cutter is selected to adopt reference line processing method at die cavity periphery processing torn edges groove, specifically adding man-hour, first roughing is carried out to the described torn edges groove first half, again roughing is carried out to described torn edges groove Lower Half, finally carry out finish-milling processing to described torn edges groove, the machining path direction of the 3rd cutter is climb cutting direction.
In the specific implementation process of the present embodiment, the processing of mold bottom boss is processed to change into by the clear angle of employing much knives and is processed by the overall finish-milling of a cutter, avoids cutter lapping defect to improve Mould Machining quality simultaneously; In addition, when torn edges slot machining, by a cutter be worked into the end change into layering process, avoid torn edges groove monolateral.
It should be noted that, in PROVIEW numerical control of machine tools software, best contour scheme refers to, cutter adds man-hour to mould, and between adjacent two gyration periods, cutter interval is equal, and when making fine finishining, die cavity inwall machining accuracy is high; Reference line processing method refers to, cutter carries out moving processing according to preset reference line, ensures torn edges slot machining precision.
In the present embodiment, the sealing ring mould processing technology proposed, in process, first large cutter is adopted to carry out roughing to mold cavity, then props is selected to be removed by the processing of clear angle many places surplus, make surplus on boss even, little cutter is finally selected to adopt best contour scheme overall processing from middle part to put in place, ensure bottom size, reduce cutter lapping defect, in addition by the method processing torn edges groove that layering is processed, avoid torn edges slot machining monolateral, improve quality and the precision of torn edges groove.By the sealing ring mould processing technology of above-mentioned optimal design, technique is simple, reasonable in design, cavity bottom boss place makes in die cavity, cutter lapping defect to be lifted, is convenient to sanding after adopting overall processing, increase work efficiency, greatly improve the machining accuracy of mould, avoid mould to scrap.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
