Abstract
The invention provides a method for machining an eccentric wheel of a press machine. The method comprises the steps that machining is conducted on a C5250 type vertical lathe, one face of a boss of a workpiece is supported by an adjustable sizing block clamp, semi-fine turning and fine turning are conducted on the outer circle of the workpiece and the other face of the boss of the workpiece so that the requirements can be met, and the consistency of the sizes of the outer circles of workpieces is within 0.02 mm; after an appropriate tool is selected, the rotation speed is determined to be 15 r/rain, the feed rate is 0.05 mm/min, the surface roughness can reach Ra3.2 through machining, and the form and location tolerance is guaranteed; an HUM surface machining device is applied to machining, wherein the rotation speed is 15 r/min and the feed rate is 0.05 mm/min. In this way, it is guaranteed that the roughness reaches Ra1.4, and the form and location tolerance is guaranteed. By the adoption of the method for machining the eccentric wheel of the press machine, the accuracy requirement can be guaranteed, the machining efficiency is high, and a high percent of pass of parts can be guaranteed.
Description
Technical field

Technical background
Forcing press is a kind of versatility forcing press of delicate structure, have of many uses, production efficiency high, forcing press can be widely used in the techniques such as cut-out, punching, blanking, bending, riveted and shaping.Make metal generation plastic deformation and fracture be processed into part by metal blank being applied to powerful pressure, eccentric wheel is the important spare part of this owner's running part, and eccentric wheel processing is very high to machine tool accuracy requirement, and difficulty of processing is large and with short production cycle.
Summary of the invention
In order to address the above problem, the invention provides one and can ensure required precision, working (machining) efficiency is high and can ensure higher part qualification rate.
Press off-centering wheel processing method of the present invention, comprises the following steps:
The first step is processed on C5250 type vertical lathe, and with the one side pad adjustable sizing block peace card of workpiece boss, half essence, finish turning excircle of workpiece and workpiece boss another side are to requiring, and excircle of workpiece dimensional uniformity is in 0.02 mm.
Second step, is to ensure the form and position tolerance of workpiece, so cutting speed, the speed of mainshaft, feed speed are:
Cutting speed
In formula: Vc is cutting speed, m/min; N is the speed of mainshaft, r/min; Dc is diameter, mm.
Table feed speed
In formula: V
ffor table feed speed, mm/min; Z is that number of teeth Wang is the amount of feeding, mm/ tooth.
The 3rd step, chooses after suitable cutter, determines that rotating speed is 15 r/rain, the amount of feeding is 0.05mm/min, can be worked into surface roughness Ra 3.2 and ensure form and position tolerance, then adopts milligram to process by HUM surface processing device, rotating speed is 15r/min, and the amount of feeding is 0.05mm/min.Thereby reach roughness Ra 1.4, and ensure size and form and position tolerance.
The 4th step, on workpiece, TK6920 type floor-type milling & boring machine is processed, workpiece pad v block peace card, centering excircle of workpiece, ensures size according to numerical control coordinate, right boring boss hole, finish-milling keyway is also symmetrical in boss hole, utilizes square chest inspection lathe X, Y, Z, W to precision before processing, and detailed record, NC compensation during for right boring hole, to reach requirement.
The 5th step, in boss hole after cold charge copper sheathing on TK6920 type floor-type milling & boring machine, between centering excircle of workpiece, keyway, symmetry reaches 0.02 mm, in.Right boring copper sleeve inner hole, roughness requires to reach Ra0.8, and ensures form and position tolerance, then on the vertical car of 5 m, uses HKUSM30 series person of outstanding talent gram energy metallic surface processing device fine finishining endoporus to roughness requirement, and finish-milling keyway is to requiring, and pin-and-hole drills and reams.
The present invention can ensure required precision, and working (machining) efficiency is high and can ensure higher part qualification rate.
