Abstract
The present invention relates to a new process for machining heavy-duty car spindle nose forge piece by using section steel, which includes: blanking section steel, heating section steel, initial forging temp. is 1150-1250 deg.C, upsetting, punching, extruding, final forging and thermal edge-cutting, its temp. is above 850 deg.C to obtain the finished product. Said invention uses section steel as base material, and adopts the process of combining thermal positive extrusion and forge to raise product quality and reduce production cost.
Description
(1) technical field
The present invention relates to a kind of new technology, belong to the moulding deformation technology of metal field with shaped steel processing heavy-duty car spindle nose forging.
(2) background technology
Spindle nose is the strength member of heavy-duty car back axle, adopts forging to finish after machined at present mostly.Its forging material therefor is a seamless steel pipe, and processing technology is blanking, and---being heated to 1150-1250 ℃---forging on the forging press---cuts edge.The deficiency that the product that processes exists is: because the wall thickness difference of seamless steel pipe itself is bigger, the pipe material is yielding, and length should not be controlled, unstable product quality; The price height of while seamless steel pipe, materials are many, and the workpiece cost is higher.
(3) summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of new technology with shaped steel processing heavy-duty car spindle nose press forging that can improve the quality of products and can reduce cost is provided.
The present invention is achieved by the following technical solutions.
This technology comprises as follows:
To the shaped blooms blanking--heating shaped steel,--jumping-up, punching--extruding--finish-forging--that initial forging temperature is 1150-1250 ℃
Hot trimming, temperature are more than 850 ℃--finished product.
The present invention is a base-material with shaped steel, and adopts hot forward extrusion and forge process combined, makes that the thick difference of arm of shaped steel workpiece is little, and size is easily grasped, constant product quality; By substituting seamless steel pipe with round steel, consumption reduces, and the cost of workpiece reduces greatly.The present invention can reduce machining allowance, makes to reduce 4-6% machining time, and material reduces 9-12%, and qualification rate improves 7-9%, and the present invention has and saves time, material-saving, product quality height, is fit to advantage such as batch process.

(5) specific embodiment
Embodiment 1: select the round steel billet blanking for use, good down round steel blank section is put into electric furnace to be heated, when being heated to 1250 ℃, temperature takes out, after the cleaning oxide layer, with 6300 tons of hotdie forging press jumping-ups, punching, extruding again, finish-forging then, as Fig. 1 to shown in Figure 5, hot trimming on 315 tons of forcing presses at last, the temperature of hot trimming is 865 ℃, cooling finished product after cutting edge, as shown in Figure 6.With the finished product contrast of original explained hereafter, reduce machining time, and 5%, material reduces 10%, and qualification rate improves 8%.
Embodiment 2: select the round steel billet blanking for use, good down round steel blank section is put into gas-fired furnace to be heated, when being heated to 1150 ℃, temperature takes out, after the cleaning oxide layer, with 1600 tons of hot horizontal forging and upsetting machine jumping-ups, punching, extruding again, finish-forging then, as the Fig. 1 to Fig. 5 among the embodiment 1, hot trimming on 315 tons of forcing presses at last, the temperature of hot trimming is 850 ℃, cooling finished product after cutting edge, as shown in Figure 6.Finished product contrast with original explained hereafter reduces 5% machining time, and material reduces 10%, and qualification rate improves 8%.
Claims (1)
1, a kind of new technology with round steel processing heavy-duty car spindle nose forging, it is characterized in that, comprise as follows, to the round steel billet blanking--the heating round steel, initial forging temperature is 1150-1250 ℃--jumping-up, punching--and extruding--finish-forging--hot trimming, temperature is more than 850 ℃--finished product.
