Abstract
A technology for manufacturing the combined toothed ring (synchronous cone) of synchronizer of speed variator of car includes such steps as rolling the blank, cold extruding by precise mould on extruder to form spline teeth and locking angle of end face, and cold extruding by precise mould on extruder to form reverse cone teeth. The combined toothed ring (synchronous cone) tooth part does not need to be cut, so that the material and the processing cost are saved, the formation of the locking angle and the inverted cone tooth on the end surface of the spline tooth is instantly finished on an extruder, the efficiency is high, the cost is low, a metal streamline is not damaged, the comprehensive mechanical property of the material is improved, the product performance is good, the quality is stable, and the use requirement of high-grade cars can be met.
Description
Technical field
The present invention relates to the preparation method of a kind of automotive transmission synchronized, belong to metalwork forging and pressing processing technique field in conjunction with ring gear.
Background technology
The automotive transmission synchronized rises when automobile changes gear synchronously and the transmission torsional interaction in conjunction with ring gear (claiming synchronous awl again), and most important, its processing request is very high.Currently used processing method generally all is first die forging blank, uses the lathe turning moulding then, with gear shapping machine processing back taper tooth, uses beveler pawl end face angle of lock at last again.There is the expense material of taking a lot of work in this method, the cost height, and production efficiency is low, and product quality be cannot say for sure defectives such as card, and especially metal streamline is cut off, and intensity is low, can occur serious consequences such as broken teeth when the transmission moment of torsion.
Summary of the invention
The objective of the invention is to overcome weak point of the prior art, provide a kind of efficient height, cost low, can enhance product performance again, the automotive transmission synchronized that guarantees product quality is in conjunction with the ring gear manufacture craft.
Technical scheme of the present invention is: the automotive transmission synchronized is adopted the processing method of rolling over ring processing and precision forging in conjunction with ring gear.The processing method of described precision forging is that the annular blank that will roll over earlier after ring is handled carries out spheroidizing, after peeling base and phospholeum processing, on extruder, adopt precision die to carry out spline tooth and increment face angle of lock cold-extrusion shaping, and then carry out the phospholeum processing, on extruder, adopt precision die to carry out the back taper extrusion molding of laughing somebody to scorn at last.
Adopt technique scheme, do not need to carry out machining in conjunction with the tooth circular tooth part again, both economical with materials was saved the machined expense again, and spline tooth increment face angle of lock and back taper tooth moment that is shaped all on extruder finishes, and efficient height, cost are low.Adopt processing method of the present invention, in conjunction with ring gear extrusion molding on precision die, do not destroy metal streamline, the material comprehensive mechanical performance increases, good product performance, and steady quality can satisfy the instructions for use of high-grade car.
The specific embodiment
Further specify embodiments of the invention below:
Get the SAE8620H Cutting stick after roll over the ring processing, form annular blank, carry out spheroidizing, peeling base then, after the phospholeum processing, on extruder, adopt precision die to carry out spline tooth and increment face angle of lock once cold extrusion is pressed into shape, again through middle phospholeum lubricated, on extruder, adopt precision die to carry out the back taper extrusion molding of laughing somebody to scorn at last.
Claims (1)
1, a kind of automotive transmission synchronized is in conjunction with the ring gear manufacture craft, earlier blank being rolled over ring handles, form processing again, the processing method that it is characterized in that described shaping processing employing precision forging, the annular blank that promptly will roll over earlier after ring is handled carries out spheroidizing, after peeling base and phospholeum processing, on extruder, adopt precision die to carry out spline tooth and increment face angle of lock once cold extrusion is pressed into shape, and then carry out the phospholeum processing, on extruder, adopt precision die to carry out the back taper extrusion molding of laughing somebody to scorn at last.
