模具的定期磨光保證了一致的沖壓質量。定期打磨模具,不僅可以提高模具的使用壽命,而且可以提高機床的使用壽命。那么打磨模具時應考慮哪些因素呢?
The regular polishing of the die ensures the consistent stamping quality. Grinding the mold regularly can not only improve the service life of the mold, but also improve the service life of the machine tool. So what factors should be considered when grinding the mold?
(1)在R01-025毫米的情況下,切削刃圓角的銳度取決于切削刃的銳度。
(1) In the case of r01-025 mm, the sharpness of the cutting edge fillet depends on the sharpness of the cutting edge.
(2)砂輪表面應清理干凈。
(2) The surface of grinding wheel shall be cleaned.
(3)建議使用松軟的粗粒砂輪。如WA46KV
(3) It is recommended to use a soft coarse-grained grinding wheel. Such as wa46kv
(4)每次研磨量(刀具)不應超過0013mm。過度磨削會導致模具表面過熱,相當于退火處理,模具變軟,大大降低模具壽命。
(4) The grinding amount (tool) per time should not exceed 0013mm. Excessive grinding will lead to overheating of the die surface, which is equivalent to annealing treatment, making the die soft and greatly reducing the life of the die.
(5)打磨時須添加足夠的冷卻液。
(5) Add enough coolant during grinding.
(6)打磨時,沖頭和下模應固定牢固,并使用專用工裝夾具。
(6) During grinding, the punch and lower die shall be firmly fixed, and special tooling fixtures shall be used.
(7)模具的研磨量是恒定的。如果達到此值,沖頭將被報廢。如果繼續使用,很容易損壞模具和機器。
(7) The grinding amount of the mold is constant. If this value is reached, the punch will be discarded. If you continue to use, it is easy to damage the mold and machine.

濟南注塑加工廠家提醒您,打磨后,應使用磨刀石處理邊緣,以去除過度鋒利的邊緣。
(8) Jinan injection molding manufacturer reminds you that after grinding, the edge should be treated with a grindstone to remove the excessively sharp edge.
(9)磨尖后,清洗、退磁、上油。
(9) After sharpening, clean, demagnetize and oil.
注意:有很多方法可以磨快模具,這可以通過一個特殊的磨刀器或在平面磨床上實現。沖頭和下模的刃磨頻率一般為4:1。磨刀后請調整模具高度。
Note: there are many ways to sharpen the mold, which can be achieved by a special knife grinder or on a surface grinder. The grinding frequency of punch and lower die is generally 4:1. Please adjust the mold height after sharpening.
(1)不正確的銳化方法的危害:不正確的銳化會加劇模具刀刃的快速損壞,導致每次銳化的錘擊次數大大減少。
(1) Harm of incorrect sharpening method: incorrect sharpening will aggravate the rapid damage of the die blade, resulting in a significant reduction in the number of hammers per sharpening.
(2)正確的刃磨方法的好處:定期對模具進行刃磨,可使沖孔質量和精度保持穩定。模具的刀刃損壞緩慢,使用壽命較長。
(2) Benefits of correct grinding method: regular grinding of the die can stabilize the punching quality and accuracy. The blade of the die is damaged slowly and has a long service life.
Technicians should understand and master basic injection molding knowledge, including low-pressure protection settings, injection speed, mold closing speed, pressure maintaining pressure, mold locking force, mold temperature and other important parameters. During production operations, try to avoid damaging the mold. Come to the website for more relevant content http://xunda-china.com Consult.
