Abstract
The precise forging technology for housing blank of constant velocity joint of car comprises two technological steps: wedged transverse rolling for volume distribution in preformation and cold extruding for forming internal hole.
Description
The invention belongs to the precision forging technology of iron and steel.
Existing external sleeve blank of CV joint for car precision forging technology is to carry out the blank processing and forming on large-scale multistation warm forging forcing press, after annealing, pickling, phosphatization are handled, and finishing on the cold forging forcing press.Because multistation cold forging machine equipment investment expense is huge, so above-mentioned technology only is adapted to the production in enormous quantities of constant velocity cardan joint blank, general annual production blank is more than 800,000; Existingly be used for, the production technology of small lot constant velocity cardan joint blank is full cold-extruded technology, owing to arranged repeatedly annealing and pickling, phosphatization operation at inter process, causes the production cost height.
The present invention avoids using expensive multistation warm forging unit, and the employing cross wedge rolling technique is finished the first two procedure in the multistation warm forging technology, two procedures after finishing with cold-extrusion technology.Production technology is reliable, and processing cost is low, in being fit to, produce the CV joint for car blank in enormous quantities.
The present invention unites the precision forging of finishing external sleeve blank of CV joint for car with two kinds of different forming methods of cross wedge rolling and cold-extrusion technology, the volume of finishing the material in the external sleeve blank of CV joint preparation moulding with cross wedge rolling distributes, and finishes the processing and forming of the endoporus of blank with cold-extrusion technology.
Accompanying drawing is a process diagram of the present invention.
With the bar blank of certain-length by after the Frequency Induction Heating, on cross wedge rolling machine, once roll into the dumbbell shape blank, thereby obtain two identical CV joint for car blanks, cut off from the centre then, after spheroidizing and pickling, phosphatization, saponification, backward extrusion endoporus on single station cold extrusion press, again through process annealing and pickling, phosphatization, saponification, finishing is shaped on cold extrusion press at last.
The present invention compared with prior art has following characteristics:
1, equipment investment is few, and equipment investment is 30% of multistation warm forging technology;
2, production cost is low, and production cost not only is lower than full cold-extruded technology, and in, be lower than multistation warm forging technology during small lot batch manufacture, also suitable substantially when producing in enormous quantities with multistation warm forging technology;
3, product quality height, because of back two road forming processes are cold extrusion processing, thus blank forming precision height, steady quality.
The present invention is specially adapted to the precision forging production of DOJ type, BJ type external sleeve blank of CV joint, is the technical scheme of a kind of small investment, instant effect, high efficiency, is fit to medium and small enterprise and carries out the technological transformation that the CV joint for car net-size forging is produced.
