The invention discloses a processing method of a bidirectional reciprocating screw, comprising the following steps: fetching a round steel with the diameter of 140 mm and length of 2370 mm; drilling A5 center holes at the two ends of the round steel; performing lathe processing on the round steel on a lathe; performing flaw detection by using 100% ultrasonic wave; milling a bidirectional spiral line for the round steel on a milling machine; tempering the hardness of the round steel with a milled bidirectional spiral line; processing the obtained round steel on the lathe; performing finish milling on the bidirectional spiral line on the lathe again; performing external milling on a round pipe to make the round pipe into a screw; performing flaw detection by using 100% magnetic powder and checking; performing chrome plating process on the screw; and polishing the chrome-plated excircle of the screw to ensure the roughness and accuracy of the excircle. The invention is convenient to operate, ensures the stability and processing rigidity, realizes high production efficiency, prolongs the service life of a cutter and reduces the processing cost.
Description
Technical field:
The present invention relates to the processing method of the bidirectional reciprocating screw on a kind of large-scale floating crane.
Background technology:
In the prior art, general diameter 120mm, length 2300mm slender axles screw rod, screw rod in machining large helix class, at first in programming, very big difficulty is just arranged, drawing requires two-way interface point place two ends circular arc to connect, secondly this circular arc is on curved surface, and not right if coordinate points has slightly, circular shape will be variant, because workpiece is longer, work in-process can produce vibrations, thereby can't guarantee its stability and processing rigidity, and cutter life is shortened, strengthened cost of processing, and production efficiency is low.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, a kind of processing method of easy to operate, bidirectional reciprocating screw that production efficiency is high is provided.
Purpose of the present invention is achieved through the following technical solutions: a kind of processing method of bidirectional reciprocating screw may further comprise the steps:
The round steel of A, cut-off footpath 140mm, it is 2370mm that the length of round steel is sawed;
B, bore the A5 centre bore at round steel two ends places;
C, round steel is machined on lathe, make the external diameter of round steel stay the 8mm surplus, the total length of round steel stays the 70mm surplus;
D, employing 100% ultrasonic wave are detected a flaw to round steel;
E, round steel is milled out the bidirectional screw line on milling machine, the groove width of bidirectional screw line is stayed the 10mm surplus;
F, the round steel that will mill out the bidirectional screw line carry out modifier treatment, and modified Brinell hardness is HB250-270;
G, with the round steel after the modifier treatment after processing on the lathe, make the round steel external diameter stay the 0.6-0.7mm surplus;
H, on milling machine, carry out finish-milling bidirectional screw line once more;
I, pipe is carried out outer mill handle, the pipe external diameter is ground little 0.025-0.035mm, make screw rod;
J, employing 100% magnetic are detected a flaw to screw rod, test with this;
K, screw rod is carried out chromium plating handle, cylindrical chromium plating bed thickness is 0.04-0.05;
L, with screw rod chrome-plated excircle polishing, guarantee the roughness and the precision of cylindrical.
The present invention compared with prior art has the following advantages: guaranteed its stability and processing rigidity, made the production efficiency height, increased the life-span of cutter, reduced processing cost.
The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment, and this embodiment only is used to explain the present invention, do not constitute the qualification to protection domain of the present invention.
The processing method of a kind of bidirectional reciprocating screw of the present invention may further comprise the steps:
The round steel of A, cut-off footpath 140mm, it is 2370mm that the length of round steel is sawed;
B, bore the A5 centre bore at round steel two ends places;
C, round steel is machined on lathe, make the external diameter of round steel stay the 8mm surplus, the total length of round steel stays the 70mm surplus;
D, employing 100% ultrasonic wave are detected a flaw to round steel;
E, round steel is milled out the bidirectional screw line on milling machine, the groove width of bidirectional screw line is stayed the 10mm surplus;
F, the round steel that will mill out the bidirectional screw line carry out modifier treatment, and modified Brinell hardness is HB250-270;
G, with the round steel after the modifier treatment after processing on the lathe, make the round steel external diameter stay the 0.6-0.7mm surplus;
H, on milling machine, carry out finish-milling bidirectional screw line once more;
I, pipe is carried out outer mill handle, the pipe external diameter is ground little 0.025-0.035mm, make screw rod;
J, employing 100% magnetic are detected a flaw to screw rod, test with this;
K, screw rod is carried out chromium plating handle, cylindrical chromium plating bed thickness is 0.04-0.05;
L, with screw rod chrome-plated excircle polishing, guarantee the roughness and the precision of cylindrical.
In process, be effective at last through debugging repeatedly, on lathe, finished the production and processing of bidirectional screw bar, thereby enhance productivity greatly, facing different size length, the screw rod of different arc sizes can both skillfully programme and process, its stability and processing rigidity have been guaranteed, make the production efficiency height, increased the life-span of cutter, reduced processing cost.
