Abstract
The invention relates to the field of machine processing, in particular to a processing method of a fan-shaped plate. The processing method comprises the following steps o blanking, carrying out preheat treatment, roughly milling the upper surface of the fan-shaped plate, roughly milling the lower surface of the fan-shaped plate, finely milling the lower surface of the fan-shaped plate by using the roughly-processed upper surface as reference, finely milling the upper surface of the fan-shaped plate, drilling, processing an outer arc, carrying out cleaning operation on the processing surface of the fan-shaped plate, removing burrs, and carrying out final heat treatment of quenching and tempering. According to the processing method disclosed by the invention, the processing accuracy and the working performance of the fan-shaped plate can be increased, the processing method is beneficial for the prolonging of the service life of the fan-shaped plate, and the production efficiency is high.
Description
Technical field
The present invention relates to field of machining, be specifically related to the processing method of fanning strip.
Background technology
The fast development of modern mechanical manufacturing industry, makes the consumption of steel in the world sharply rise.Along with industrial production is to the wilderness demand of steel, the equipment of multiple production steel is also come out one after another, and coiling machine is exactly wherein very important a kind of equipment.Present steel major part is all by hot rolling or cold rollingly forms, and for the ease of storing and transport, needs, with coiling machine, steel are batched rolling tubular.The appearance of coiling machine substantially increases the production efficiency of smelting steel industry.Coiling machine is generally made up of parts such as reel, reducing gear, casing, bases, and fanning strip is a vital part in reel, and the machining accuracy of fanning strip and performance directly have influence on the duty of whole coiling machine.Meanwhile, fanning strip has the features such as complex-shaped, procedure of processing is many, is process a very complicated part in coiling machine.Its Design Processing needs to consider many-sided factor, needs to select optimum scheme, just can produce qualified fanning strip.For coiling machine, a machining accuracy fanning strip that is high, favorable working performance can greatly reduce its rate of breakdown, improves the utilization rate of machine, and the modernization for steel is produced in enormous quantities very important meaning.
Processing at present for plane is generally turnery processing, because fanning strip is an irregular part, adopt turning, conventional brace, such as scroll chuck, the installation of Double Tops point etc. are not all suitable for fanning strip, therefore need the special fixture designing fanning strip, this will increase production cost and the amount of labour of part greatly, reduce production efficiency.
Summary of the invention
In order to solve the problem, the invention provides one and can improve fanning strip machining accuracy and service behaviour, be conducive to fanning strip service life, the processing method of the fanning strip that production efficiency is high.
The processing method of fanning strip of the present invention, comprises the following steps:
The first step, blanking, selects suitable blank, and blank material and part shape are more close better;
Second step, conditioning treatment, carries out annealing and adds modifier treatment;
3rd step, rough mills the upper surface of fanning strip, selects X63 horizontal milling machine, and take lower surface as the upper surface that roughing standard rough mills fanning strip, surface roughness reaches Ra12.5;
4th step, rough mills the lower surface of fanning strip, and with rough machined upper surface for benchmark, surface roughness can reach Ra6.3;
5th step, finish-milling fanning strip lower surface, with fanning strip upper surface for smart benchmark finish-milling fanning strip lower surface, surface roughness reaches Ra3.2;
6th step, finish-milling fanning strip upper surface, with fanning strip lower surface for benchmark finish-milling fanning strip upper surface, surface roughness is Ra6.3;
7th step, boring, the lower surface selecting fanning strip is benchmark, bores the through hole on fanning strip, according to the order of processing of first holing, then slightly ream, finally finish ream, processes, ensure that the precision in hole meets the demands to institute is porose;
8th step, the processing of external arc, selects the lower surface of fanning strip and the center line in hole to be benchmark, selects X63 milling machine to divide to rough mill to process with finish-milling two external circular arcs;
9th step, carries out cleaning operation to fanning strip finished surface, rejects burr, and carry out quenching, tempering finished heat treatment.
The present invention can improve fanning strip machining accuracy and service behaviour, and be conducive to fanning strip service life, production efficiency is high.
