Description
Technical field
The present invention relates to Press Tools for Automobiles processing technique fields, and in particular to a kind of Press Tools for Automobiles trimming edge adds
Work method.
Background technique
Trimming edge is the important component that auto sheet feeder is cut in Press Tools for Automobiles, and the quality height of trimming edge is
Measure one of the major criterion of Press Tools for Automobiles manufacture level height.The processing of trimming edge, is usually quenched first, so
Whole cutting forming afterwards, wherein intensity and the service life of trimming edge can be improved in quenching treatment, although however, quenching is improved and repaired
Side cutting edge rigidity, hardness, fatigue strength, wearability etc., but can also trimming edge be made to become fragile, thus in postorder cutting process
Easily there is chipping, chipping meeting occurs so that trimming edge generates defect, and then generates extreme influence, Zai Yifang to total quality
Face needs to go out to repair to chipping, and then need to put into great man power and material, then repairing knot when there is chipping
Often there are huge differences with normal outcome for fruit, can seriously affect the process-cycle.
In consideration of it, special propose the invention.
Summary of the invention
For the deficiencies in the prior art, the purpose of the present invention is to provide a kind of Press Tools for Automobiles trimming edges
Processing method can effectively solve trimming edge process for the machine-shaping of trimming edge part in Press Tools for Automobiles
In the problem of being easy to appear chipping, guarantee the quality of trimming edge, use manpower and material resources sparingly simultaneously, guarantee the process-cycle.
The technical proposal of the invention is realized in this way:
A kind of Press Tools for Automobiles trimming edge processing method, includes the following steps:
Step 1: functional area quenching；
Step 2: the cutting of functional area aniseed, allowance are 0.1 ± 0.02mm；
Step 3: functional area finish cutting, allowance are 0.05 ± 0.01mm；
Step 4: functional area and non-functional area cutting, allowance is 0mm.
Step 5: surface polishing.
Further, in step 2, when cutting, the pick feed amount of cutter is 1 ± 0.2mm, the feeding of cutter is 1600 ±
100mm/min, the revolving speed of cutter are 2000 ± 200r/min.
Further, in step 3, when cutting, the pick feed amount of cutter is 0.4 ± 0.1mm, and the feeding of cutter is 3000
± 100mm/min, the revolving speed of cutter are 3500 ± 200r/min.
Further, in step 4, when cutting, the pick feed amount of cutter is 0.4 ± 0.1mm, and the feeding of cutter is 5000
± 100mm/min, the revolving speed of cutter are 5500 ± 200r/min.
Further, in step 2 ~ step 5, blade cut functional area after fire is used.
Further, Step 2: in step 3 and step 4, the edge along trimming edge is cut.
The beneficial effects of the present invention are:
(1) to functional area (portion when functional area, that is, later period cuts auto sheet feeder using trimming edge, for cutting
Position, the usually position at trimming edge edge) quenching treatment, improve its hardness, facilitate the later period using when cut auto sheet feeder more
Accelerate victory, functional area and non-functional area are processed respectively after quenching, and then solves whole to trimming edge in the prior art
Easily there is the problem of chipping in body cutting forming, and then can guarantee the quality of trimming edge, uses manpower and material resources sparingly simultaneously, guarantees to add
The work period.
(2) in step 2, when cutting, cutter pick feed amount is 1 ± 0.2mm, and the feeding of cutter is 1600 ± 100mm/
Min, the revolving speed of cutter are 2000 ± 200r/min, which is aniseed cutting, can ignore the coarse of processing rear mold surface
Degree, therefore biggish cutter pick feed amount is used, aniseed can be quickly machined away, while using lesser cutter revolving speed, root
It is cutting speed according to following formula Vc=(π dn)/1000, Vc, d is cutter diameter, and n is cutter revolving speed, is turned using lesser cutter
Speed can reduce cutting speed, and cutting force is proportional to cutting speed, and cutting force, lesser cutting can be reduced by reducing cutting speed
Power can prevent chipping, while improve cutting-tool's used life.
(3) in step 3, when cutting, cutter pick feed amount is 0.5 ± 0.1mm, the feeding of cutter is 3000 ±
The revolving speed of 100mm/min, cutter are 3500 ± 200r/min, which is finish cutting, need to guarantee to process rear mold surface
Finish, therefore lesser cutter pick feed amount is used, prevent cutting excessively, while using biggish cutter revolving speed, it can be with
Guarantee processing after die surface finish, since cutter pick feed amount is smaller, biggish cutter revolving speed will not generate compared with
Big cutting force, therefore chipping will not be generated, cutting-tool's used life will not be impacted.
(4) in step 4, when cutting, cutter pick feed amount is 0.4 ± 0.1mm, the feeding of cutter is 5000 ±
100mm/min, the revolving speed of cutter are 5500 ± 200r/min, which is the last flow of cutting, in conjunction with beneficial effect (3),
The pick feed amount for further decreasing cutter improves the revolving speed of cutter to guarantee cutting effect.
(4) in step 2 ~ step 5, using blade cut functional area after fire, after fire blade stiffness HRC55-60 it
On, expense material can be quickly machined away using blade after fire；Step 2: in step 3 and step 4, along the edge of trimming edge into
Row cutting, is cut along the vertical direction of trimming edge in the prior art, cutting easily occurs and chipping, this hair excessively occurs
The bright edge along trimming edge, which carries out cutting, effectively to solve the above problems.
