Description
Technical field
It is the surface of revolution, the metal working process for having more complex subtle slight arc variation that invention, which is related to a kind of outer profile,
Specially a kind of engine top rod mold processing technology.
Background technique
Engine top rod mold mostly uses heat-resistance stainless steel to meet such mold to the service life, and extrusion deformation degree impacts, resistance to
The requirement of thermal deformation behavior, the processing technology taken in the past are a series of for rough turn, heat treatment, grinding and electrical discharge machining etc.
Processing method, or numerically-controlled machine tool is used, but cutting parameter therein, cutter, lathe revolving speed and dimensional tolerance control are not reasonable,
And heat-resistance stainless steel is processing the surface of revolution and if cutter and process velocity selection are improper when having frequent profile variations, easily bursts apart,
Residualinternal stress causes die life during fabricating mandril to reduce, and the tolerance of long term thermal is not high, is easily cracked even
Generating peeling pit causes mold to be scrapped.
Summary of the invention
To overcome prior art adverse effect caused by mold during processing mold, according to mold body profile
The invention proposes a kind of new top rod mold processing technology for characteristic and use occasion.
Key to the invention is that the control to machining allowance, tool type, cutting-tool angle, depth of cut and process velocity is real
Existing goal of the invention:
1. roughing outer circle puts 0.1mm surplus；
2. roughing exit orifice selects the cutter of the point of a knife of 85 ° of diamond shape R0.8mm；
3. roughing inner hole selects the cutter of 80 ° of brilliant points of a knife, nose radius is between 0.4mm~0.8mm and is less than
0.8mm stays 0.1mm machining allowance to process inner hole；
The above three steps revolving speed turns in 1200r/min~1600r/min, depth of cut 0.5mm, feed F=0.15mm/；
4. after the completion of roughing, fine turning outer circle in place: select triangular knife, the point of a knife of point of a knife and roughing inner hole cutter for same
Radius is consistent；Inner hole selects 75 ° of brilliant R0.2mm point of a knife blades；
5. 80 ° of brilliant R0.03mm point of a knife blade processing are selected in machine-shaping step and inclined-plane connection；Finish revolving speed
Control is in 2000~2400r/min, and the control of single side depth of cut turns in 0.05mm, feed F=0.03mm/, to reach
Internal diameter is connect with the connected inclined-plane for being connected in 2 ° ± 0.1 ° of molding；
Reaching inner hole to form surface roughness to the control of cutter and revolving speed by above two step is Ra1.6 μm；
6. being detected after process finishing by contourgraph and projector.
Wherein roughing is completed with difference batch is finished, and not on a machine tool, frequent switching finish or slightly adds
Work.
Skill scheme of the present invention can control processing heat in the range of material can be born, and the depth of cut and walk
The control of knife amount can be effectively controlled the generation of uneven internal stress, prevents from bursting apart, substantially reduces defect rate.
Detailed description of the invention
Fig. 1 is the schematic cross-section of top rod mold.
Specific embodiment
The rapidoprint of the present embodiment is H13 mould steel；
1. roughing outer circle puts 0.1mm surplus；
2. roughing exit orifice selects the cutter of the point of a knife of 85 ° of diamond shape R0.8mm；
3. roughing inner hole, selects the cutter of 80 ° of brilliant points of a knife, nose radius 0.4mm stays 0.1mm machining allowance
Process inner hole；
The above three steps revolving speed turns in 1500r/min, depth of cut 0.5mm, feed F=0.15mm/；
4. after the completion of roughing, fine turning outer circle in place: select triangular knife, nose radius 0.4mm；Inner hole selects 75 ° of diamonds
Type R0.2mm point of a knife blade；
5. 80 ° of brilliant R0.03mm point of a knife blade processing are selected in machine-shaping step and inclined-plane connection；Finish revolving speed
In 2000r/min, the control of single side depth of cut turns in 0.05mm, feed F=0.03mm/ for control, thus reach internal diameter with
The connected inclined-plane connection for being connected in 2 ° ± 0.1 ° of molding；
Reaching inner hole to form surface roughness to the control of cutter and revolving speed by above two step is Ra1.6 μm；
6. being detected after process finishing by contourgraph and projector.
Specific process is:
Blank with molded aperture is accommodated on numerically-controlled machine tool, to knife, adjusts machine spindle speed in 1500r/
Min, depth of cut 0.5mm, feed F=0.15mm/ turn, and roughing exit orifice selects the cutter of the point of a knife of 85 ° of diamond shape R0.8mm
Roughing outer circle puts 0.1mm surplus, and roughing inner hole selects the cutter of 80 ° of brilliant points of a knife, and nose radius 0.4mm is stayed
0.1mm machining allowance processes inner hole；After the completion of roughing, fine turning outer circle in place, complete by the above manufacturing batch, selects triangle later
Knife, nose radius 0.4mm, inner hole are selected 75 ° of brilliant R0.2mm point of a knife blades, machine-shaping step and inclined-plane connection, are selected
80 ° of brilliant R0.03mm point of a knife blade processing；Finishing revolving speed is controlled in 2000r/min, and the control of single side depth of cut exists
0.05mm, feed F=0.03mm/ turn, and connect, finish with the connected inclined-plane for being connected in 2 ° ± 0.1 ° of molding to reach internal diameter
Also batch is completed, and reaching inner hole to form surface roughness to the control of cutter and revolving speed by above two step is Ra1.6 μm, processing knot
It is detected after beam by contourgraph and projector.
