Description
Technical field
The invention belongs to screw-thread steel Roller Machining technical field, be specifically related to the processing method of a kind of high-speed steel, high boron steel roll crescent.
Background technology
The processing of roll is mainly used for the rolling of reinforcing bar finished product, in the process of reinforcing bar rolling, needs to demonstrate certain cross rib on the reinforcing bar of finished product.Roll material used substantially all belonged to iron rod in the past, and processing is got up easily, but poor durability, in order to solve durability issues, generally adopt the high-speed steel of high strength and high hardness, high boron steel as roll material at present.Due to the particularity of high-speed steel, high boron steel material, there is larger difficulty in the processing of crescent, be mainly manifested in: the process-cycle of high-speed steel, high boron steel roll is long for iron rod, and production efficiency is low; Loss for cutter strengthens, thus affects the crudy of roll crescent, so affect reinforcing bar go out yield rate, cause the heavy problem such as unstable of the rice of reinforcing bar.The present invention aims to provide the processing method of a kind of high-speed steel, high boron steel roll crescent, and under the prerequisite ensureing Milling Process quality, shorten the process-cycle, reducing cutter loss, is enterprise's cost efficiency.
Summary of the invention
The object of the present invention is to provide the processing method of a kind of high-speed steel, high boron steel roll crescent.
The object of the present invention is achieved like this, and the processing method of described high-speed steel, high boron steel roll crescent comprises grinding milling cutter, clamping and Milling Process operation, specifically comprises:
A, grinding milling cutter: cross rib top width to the 0.85 ~ 1.55mm strengthening cutter when milling lathe tool grinding, makes the side of milling lathe tool become arc chord angle from original corner angle;
B, clamping: milling lathe tool is installed on lathe, and clamping roll to be processed, the angle of adjustment push rod and crescent minute of angle, namely the helical angle of roll crescent is 56 ~ 58.5 °;
C, Milling Process: it is 45 ~ 55% of rated value that adjustment adds the rotating speed in man-hour; Adjustment simultaneously adds the depth of cut in man-hour and corresponding processing number of times is: the first cutter depth of cut 0.05mm, processing number of times 10 ~ 15 times; Second cutter depth of cut 0.03mm, processing number of times 18 ~ 20 times; 3rd cutter depth of cut 0.02mm, till machine-shaping, process time is 45 ~ 90min/ groove.
Processing method of the present invention is on the one hand by strengthening cutter cross rib top width when milling lathe tool grinding, the flank of tool is made to become arc chord angle from original corner angle, to reduce in process the wearing and tearing of cutter, effectively extend the service life of carbide cutter tool, also improve crudy and working (machining) efficiency.Added the depth of cut and the feed number of times in man-hour on the other hand by adjustment, under the prerequisite shortening the process-cycle nearly 40%, improve machining accuracy, the roll rice produced is heavily stable, reliable in quality.
