The components of the forged blank in this embodiment are calculated by weight percentage: C: 0.64%, Si: 0.20%, Mn: 1.03%, S: 0.01%, P: 0.012%, Cr: 0.15%, Ni: 0.02% , Cu: 0.04%, the rest is Fe;

[0049] (2) Annealing treatment of forging blank:

[0050] The forged blank in step (1) is annealed in an annealing furnace to reduce the hardness and change the cutting performance. The hardness after annealing treatment is HB 225;

[0051] (3) Rough machining of forging blanks:

[0052] After the annealing tr...

Embodiment 2

[0069] A kind of tool seat processing method with locking device in this embodiment, its specific processing steps are the same as embodiment 1, the difference is:

[0070] The composition of the forged blank of the tool seat in step (1) is calculated by weight percentage: C: 0.63%, Si: 0.22%, Mn: 0.98%, S: 0.01%, P: 0.012%, Cr: 0.19%, Ni : 0.02%, Cu: 0.05%, the rest is Fe;

[0071] The annealing temperature in step (2) is 780°C, and the annealing time is 6 hours;

[0072] Step (4) In the heat treatment of the tool holder, heat to 830°C within 20 minutes, and then quench after holding the heat for 45 minutes. The quenching medium is 2# quenching oil, and then temper twice at 450°C. The hardness of the obtained tool holder is HRC45;

[0073] Step (5) blackening treatment of the knife seat: After wire cutting, the knife seat is degreased and degreased, and then discolored in a mixed solution of sodium hydroxide, sodium nitrite, sodium nitrate and water, in which: sodium hydrox...

Embodiment 3

[0075] A kind of tool seat processing method with locking device in this embodiment, its specific processing steps are the same as embodiment 1, the difference is:

[0076] The composition of the forged blank of the tool seat in step (1) is calculated by weight percentage: C: 0.65%, Si: 0.19%, Mn: 1.1%, S: 0.009%, P: 0.014%, Cr: 0.2%, Ni : 0.017%, Cu: 0.046%, the rest is Fe;

[0077] The annealing temperature in step (2) is 840°C, and the annealing time is 4 hours;

[0078] Step (4) In the heat treatment of the tool holder, heat it to 830°C within 20 minutes, keep it warm for 45 minutes and then quench it. The quenching medium is 2# quenching oil, and then temper twice at 480°C. The hardness of the obtained tool holder is HRC43;

[0079] Step (5) blackening treatment of the knife seat: After wire cutting, the knife seat is degreased and degreased, and then discolored in a mixed solution of sodium hydroxide, sodium nitrite, sodium nitrate and water, in which: sodium hydroxide...

Abstract

The invention discloses a processing method of a tool apron with a locking device, belonging to the technical field of tool apron processing. The method comprises the following steps: (1) the preparation of raw materials of the tool apron; (2) the annealing treatment of forging blank, wherein the annealing temperature is 780-840 DEG C, and the annealing time is 4-6 hours; (3) the rough processing of forging blank; (4) the heat treatment of the tool apron: heating to 830 DEG C within 20 minutes, quenching after 45 minutes of heat preservation, wherein a quenching medium is No. 2 quenching oil, and then tempering for two times under the temperature of 450-480 DEG C; and (5) the deep processing of the tool apron: cutting gaps and circular arc segments with a wire cutting method, and blackening the tool apron. In the processing, the locking device is formed, the tool apron can still be firmly locked on a cutter shaft not to loosen when the cutter shaft rotates at a high speed, the requirement that the face runout value of the tool apron is controlled within 0.002 mm is achieved, and the demand that users cut metal plates such as high-precision aluminum plates, stainless steel plates, silicon steel plates and the like is met.

Description

technical field [0001] The invention relates to the technical field of tool holder processing, and more specifically relates to a tool holder processing method with a locking device. Background technique [0002] The sheet metal slitting machine relies on the rolling scissors to roll on the sheet to complete the infinitely long shearing action of the sheet. The sheet metal slitting machine is used for longitudinal rolling shearing of ordinary metal sheets, aluminum sheets, stainless steel sheets, silicon steel sheets, etc. Rolling scissors are widely used in aerospace, automobile manufacturing, mining machinery, hardware manufacturing, home appliances and other industries. When cutting, the rotation of the roller scissors is driven by the knife seat locked on the knife shaft. Whether the knife seat can be fastened on the knife shaft and whether the knife seat deflects after fastening is directly related to the quality of the cut material. Generally, the tool seat is faste...
