Abstract

The invention discloses a machining method for a toothed long cutter applicable to glasses cloth cutting and belongs to the technical field of mechanical blades. The machining method comprises the steps that (1) raw materials are prepared; (2) annealing is conducted, specifically, the temperature of annealing is 830-860 DEG C, a heat preserving furnace is cooled to 720-740 DEG C, heat preserving is conducted, cooling with a furnace is conducted again till the temperature reaches 500-530 DEG C, and the raw materials are taken out from the furnace and subjected to air cooling; (3) blank forging and rough machining are conducted; (4) heat treatment is conducted, specifically, annealing is conducted, that is, the long cutter is subjected to annealing again before quenching and heated to the temperature of 600-630 DEG C, after heat preserving, cooling with the furnace is conducted till the temperature reaches 500 DEG C, and the long cutter is taken out from the furnace and subjected to air cooling; quenching is conducted, that is, the toothed long cutter is heated to the temperature of 620-660 DEG C for the first time, subjected to heat preserving for 0.5-1 h, then preheated for the second time, heated up to 820-860 DEG C, subjected to heat preserving again for 0.5-1.5 h, finally heated up to 1000-1050 DEG C, taken out from the furnace and subjected to oil quenching; and tempering is conducted, that is, the toothed long cutter is subjected to tempering at the temperature of 550-560 DEG C for the first time, heat preserving is conducted, then tempering is conducted at the temperature of 560-570 DEG C for the second time, and the toothed long cutter is cooled and taken from the furnace after heat preserving; and (5) finish machining is conducted. The properties of the prepared toothed long cutter can meet the cutting requirement of a glasses cloth, and the obtained glass cloth is good in appearance quality.

Description

technical field [0001] The invention relates to the technical field of mechanical blades, in particular to a processing method of a toothed long cutter suitable for cutting glasses cloth. Background technique [0002] Glasses cloth is an indispensable accessory for glasses wearers, especially for glasses with high-quality lenses. In order to meet the requirements of good lens wiping effect and no damage to the lenses, the texture requirements of the glasses cloth are higher; On the other hand, for glasses with high-quality lenses, higher and higher requirements are placed on the appearance and feel of the glasses cloth. [0003] The shape of glasses cloth is mostly square, and tooth-shaped structures are arranged around it. At present, manufacturers of spectacle cloths often use square dies to punch out each spectacle cloth. Using this punching method can ensure that the cut out spectacle cloth has a regular shape and will not be deformed. The surrounding force is uniform,...
