The processing method of the steel mechanical transmission belt wheel of described roll forming is as follows:
The first step, blanking carries out blanking by the developed area of belt wheel;
In second step, the pull and stretch punching is carried out the pull and stretch piercing with the pull and stretch punching hole composite die, must treat the roll extrusion pulley blanks, forms connecting bushing, connects end face and is connected the shaft shoulder;
In the 3rd step, the bench drill processing mounting holes is used in mounting hole processing;
In the 4th step, the roll extrusion trough of belt carries out roll extrusion with the trough of belt rolling forging die to connecting the shaft shoulder, forms the trough of belt and the afterbody shaft shoulder;
Described trough of belt rolling forging die comprises moulding plug, circumferential locating stud, trough of belt milled head and thimble, the moulding plug is a ledge structure, its right-hand member is provided with the shaft shoulder of lathe three jaw chuck clamping, the centre is provided with the trough of belt chamber, center at its left end is provided with center hole, is convenient to lathe tail cone jacking, the right-hand member lathe three jaw chuck clamping of moulding plug, thimble is installed on the tailstock of lathe, and the trough of belt milled head is installed on the middle carriage of lathe.
The claimant has carried out rolling finishing at engine lathe, the shaft shoulder of moulding plug right-hand member is clamped on the three melon chucks, thimble is contained on the tailstock, withstand in the center hole of moulding plug left end, the trough of belt milled head is installed on the middle carriage, during roll extrusion, to treat that the roll extrusion pulley blanks is sleeved on the moulding plug, make with circumferential locating stud and to treat that the roll extrusion pulley blanks fixedlys connected with the moulding plug, regulating middle carriage makes the trough of belt milled head in the trough of belt chamber that axially aligns on the moulding plug, start lathe, make the motion that rotates in a circumferential direction of moulding plug, treat that the roll extrusion pulley blanks rotates thereupon under the drive of circumferential locating stud, middle carriage is moved radially, the trough of belt milled head moves radially, and by the roll extrusion mode belt wheel cylindrical shaft shoulder is formed and connects the shaft shoulder, the trough of belt and the afterbody shaft shoulder.
The gained belt wheel is through the reality use test of installing, the steel belt wheel intensity of roll forming can satisfy usage requirement, and weight only is 1/3～1/6 of foundry goods belt wheel weight, and overall cost descends 30%～60%, as long as manufacture cycle is 2 minutes, and the manufacture cycle of foundry goods belt wheel generally more than 3 days, this shows that not only product performance are reliable for the steel belt wheel of roll forming, and manufacturing efficiency height, with low cost, meet the diesel engine loss of weight and fall this requirement, competitive advantage is remarkable.
