Abstract
The manufacture process of main cylinder for hydraulic brake of automobile includes multiple drawing steel plate to form cylinder blank, fine turning, superfine rolling to machine inner cylinder hole, punching steel plate and interference pressing-in to form the cylinder flange, resistive welding cylinder with oil cup to form the oil hole of the cylinder, and arc strike welding the oil outlet hole material to the cylinder and drilling hole to form the oil outlet hole. The present invention adopts cold drawing machining and new arc strike welding technique to replace casting process, and has improved work condition, environment protection, saving in power consumption, shortened machining process, raised material utilization and raised product endurance.
Description
One, technical field
The present invention relates to a kind of manufacture method of cylinder body of automobile hydraulic brake master.
Two, background technology
The method that the manufacturing of the cylinder body of existing automobile hydraulic brake master all adopts casting (cast aluminium or cast iron) to be shaped.The cylinder body profile that casts out is coarse, processing time-division prtreatment, fine limit work, finish ream, multiple working procedure such as honing, manufacturing procedure is complicated, its stock utilization low (only up to about 50%), and the as cast service conditions is abominable, easily causes environmental pollution, and energy utilization rate is also very low.Simultaneously, there are deficiencies such as loose, pore, folder quarrel, shrinkage inevitably by the cylinder body of cast form.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and a kind of manufacture method with cylinder body of environmental protection and energy saving, automobile hydraulic brake master that stock utilization is high is provided.
Purpose of the present invention realizes by following technical solution: a kind of manufacture method of cylinder body of automobile hydraulic brake master, at first steel plate materials is carried out repeatedly stretch forming to make cylinder blank, adopt finish turning processing then, super smart rolling and processing goes out the endoporus of cylinder body, adopts that interference is pressed into this cylinder body to form the flange of cylinder body after the steel plate materials drawing again; Adopt the welding of cylinder body and oil-feed cup flash butt welding to form the fuel feed hole of cylinder body; Adopt cylinder body and the arcing of oil outlet blank weldering welding back boring to form the oil outlet of cylinder body, finally make the cylinder body of this master brake cylinder.
Because the present invention is the cylinder body manufacture method that adopts stretching cool working and arcing weldering new process, replace the manufacture method of former cast form, its beneficial effect is: improved service conditions, played the effect of environmental protection and energy saving; Shorten manufacturing procedure, improved stock utilization, and improved the durability of products energy.
Four, the specific embodiment
The present invention is described in further detail below in conjunction with embodiment.
The manufacture method of the cylinder body of automobile hydraulic brake master of the present invention is: at first (use punch press) carries out repeatedly stretch forming to make cylinder blank to steel plate materials (should meet stretches requires), (use lathe) adopts finish turning processing then, super smart rolling and processing goes out the endoporus of cylinder body, and interference was pressed into this cylinder body to form the flange (flange that is cylinder body is that interference is pressed into cylinder body after adopting the steel plate drawing in addition) of cylinder body after (working pressure machine) adopted the steel plate materials drawing again; (use resistance welding machine) adopts cylinder body and the welding of oil-feed cup flash butt welding to form the fuel feed hole of cylinder body; (using the arcing welding machine) adopts cylinder body and oil outlet blank arcing weldering welding back boring to form the oil outlet of cylinder body, finally makes the cylinder body of this master brake cylinder.
Because this manufacture method has adopted stretching cool working and international advanced technology arcing weldering new process, thereby has cancelled former casting forming process, has improved service conditions, has improved stock utilization (stock utilization is brought up to 70-80%); Simultaneously because tissue density's height of cylinder body, thereby improved the durability of products energy.
