Abstract
The invention discloses a method for machining an oblique tooth/helical tooth spline on a cold striking machine, and belongs to the field of oblique tooth/helical tooth spline processing and forming. The method is characterized in that firstly, a workpiece (1) is clamped on the axis O-O' of the cold striking machine through a clamping mechanism (3), the clamping mechanism (3) used for controlling the workpiece (1) to carry out indexing rotation around the axis of the workpiece is connected with an indexing mechanism (4) of the cold striking machine, a left rolling wheel and a right rolling wheel (2, 2') are horizontally and symmetrically arranged on the two sides of the axis of the workpiece (1) respectively, the intersection angles of the axes of the left rolling wheel and the right rolling wheel (2, 2') are respectively gamma, and the gamma is the helical angle of the oblique tooth/helical tooth; secondly, the relationship among all parameters in a cold striking process is calculated and confirmed, and is confirmed by a formula (1), the axial feed amount L and the indexing angle alpha of the workpiece are calculated according to the formula (1), and the workpiece is processed in this way. In the process of cold striking, the workpiece is reallocated according to the size of plastic deformation metal to form a spline tooth groove, the integrality of a metal flow line is guaranteed, and the synthesized mechanical property of a spline is improved.
Description
Technical field
The invention belongs to helical teeth/helical tooth spline and shape the field, be specifically related to a kind ofly strike the method that machine is processed helical teeth/helical tooth spline cold.
Background technology
It is good that helical teeth/helical tooth has a flank of tooth contact, and contact ratio is big, stable drive, makes advantages such as mechanism's compactness, is widely used in all kinds of mechanical fields.The method of processing and manufacturing helical teeth/helical tooth spline mainly is metal-cutting machining method both at home and abroad at present, method commonly used is mill teeth, gear hobbing and gear shaving machine processing, production efficiency is low, and the process metallic fiber is cut off, and has reduced mechanical performance of products greatly.
Summary of the invention
The purpose of this invention is to provide and a kind ofly strike the method that machine is processed helical teeth/helical tooth spline cold, can overcome lacking that prior art exists effectively.Procedure of processing of the present invention and feature thereof are shown in Fig. 1,2,3,4.
1. workpiece 1 usefulness clamp mechanism 3 is clamped on the cold axes O-O ' that strikes machine, is used for control workpiece 1 and is connected with the cold indexing mechanism 4 that strikes machine around the clamp mechanism of self axis calibration rotation; With about temper wheel 2,2 ' horizontal symmetrical be installed in the axis both sides of workpiece 1 respectively, about the temper angle of wheel 2,2 ' axis be respectively γ, the γ angle is the helical angle of helical teeth/helical tooth spline.
2. coldly strike that the pass between the various technological parameters is in the process:
In the formula: the t-wheel of tempering whenever turns around the used time
The rotating speed of the n-wheel of tempering
α-minute of angle
L-the wheel of tempering beats once workpiece, and workpiece is along the amount of feeding of axis
V-workpiece is along the feed speed of axis
S-interrupted division chord length
D-workpiece external diameter
β-workpiece helical angle
Division angle alpha in the time of can calculating the workpiece axial feeding and be L according to following formula is processed workpiece according to this, can process high accuracy, high-quality helical teeth/helical tooth spline.
Advantage of the present invention and good effect are: adopt the present invention and process helical teeth/helical tooth spline, utilize the percussion of the wheel of tempering, plastic deformation takes place in workpiece under the surge effect of the wheel of tempering, form the spline teeth groove.Workpiece relies in the plastic history metal volume to redistribute and forms the spline teeth groove, does not cause waste of material and has guaranteed the integrality of metal streamline; Metal generation flow harden effect in the plastic history, making deformed region is that spline tooth case hardness, precision and wearability are improved, thereby makes the comprehensive mechanical performance of spline be better than the spline of machining; In addition, because the cold process velocity that strikes far above machining, has therefore improved the working (machining) efficiency of spline.
