Abstract
The invention relates to a spline extrusion manufacturing method. The extrusion manufacturing method adopts an axial forming technology falling into a one-time forming and a pulsed step-by-step forming. The two technologies respectively comprise the following steps: the one-time forming comprises the steps of: 1) pushing a to-be-processed spline part of a workpiece into a first forming die along the axial direction; and 2) performing extrusion forming by the first forming die under external extrusion force, at the same time pulling the workpiece out along the axial direction, and keeping the workpiece away from the first forming die; and the pulsed step-by-step forming consists of the steps of: 1) pushing a to-be-processed spline part of the workpiece into a second forming die along the axial direction; 2) clamping and fixing the workpiece through a clamping device; 3) clamping and fixing the second forming die through a reinforcing steel strip; and 4) conducting extrusion forming by the second forming die under external extrusion force. The method provided by the invention can process some structure products that cannot be realized by cold rolling spline process.
Description
Technical field
The invention belongs to spline manufacture method technical field, particularly relate to a kind of spline extruding method for making.
Background technology
The scheme of existing manufacture spline is spline cold rolling making method, is that employing two pieces of spline template rollings form spline.Its defect existed is: 1), machining accuracy is poor, comprises form error (profile of tooth, teeth directional, week tire out); 2), material hardness is larger to spline Accuracy; 3), spline processing length is by the restriction of template width; 4), hollow pipe product cannot be processed.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and a kind of spline extruding method for making is provided, the irrealizable infrastructure product of some cold rolling for making spline techniques can be processed.
The object of the invention is to have come by following technical solution, this extruding method for making adopts axial forming technique, and this axial forming technique is divided into once-forming and pulsed to be shaped step by step, and its two kinds of technology comprise the steps: respectively
Once-formingly to comprise the following steps: 1), the splined section of processing needed for workpiece is pushed in the first shaping dies vertically; 2), this first shaping dies by extraneous extruding force extrusion molding, workpiece is pulled out vertically simultaneously, makes workpiece away from the first shaping dies;
Pulsed is shaped step by step and comprises the following steps: 1), push in the second shaping dies vertically by the splined section of processing needed for workpiece; 2), workpiece is fixed by gripping means grips; 3), the second shaping dies adds fasten by reinforcing steel band; 4), this second shaping dies is by extraneous extruding force extrusion molding.
As preferably, the first described shaping dies and the second shaping dies adopt high strength cemented carbide to make, and surface scribbles coating; Wherein the inner core die wall of the second shaping dies is provided with the spline processing tooth of more than at least two-stage.
As preferably, described pulsed step by step forming technique can processing thin-walled class part spline, processing blind hole internal spline and two-stage with upper spline.
As preferably, described workpiece be hollow bloom or workpiece porose after processing time, push core vertically in the hollow hole of now this workpiece.
Beneficial effect of the present invention is: the method can meet the high accuracy spline tolerance of some high-end customers, and can process the irrealizable infrastructure product of some cold rolling for making spline techniques, is improving product class and extended products type effective way; Have 1), improve spline machining accuracy, 2), reduce material hardness to the impact of spline precision, 3), spline processing length can set the stroke of equipment, wide ranges, 4), the advantage of hollow pipe spline can be processed.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to the present invention: as shown in accompanying drawing 1,2, extruding method for making of the present invention adopts axial forming technique, this axial forming technique is divided into once-forming and pulsed to be shaped step by step, and its two kinds of technology comprise the steps: respectively
Once-formingly to comprise the following steps: 1), the splined section 11 of required for workpiece 1 processing is pushed in the first shaping dies 2 vertically; 2), this first shaping dies 2 by extraneous extruding force extrusion molding, workpiece 1 is pulled out vertically simultaneously, makes workpiece 1 away from the first shaping dies 2;
Pulsed is shaped step by step and comprises the following steps: 1), push in the second shaping dies 4 vertically by the splined section 11 of required for workpiece 1 processing; 2), workpiece 1 is fixedly clamped by clamping device 3; 3), the second shaping dies 4 adds fasten by reinforcing steel band 5; 4), this second shaping dies 4 is by extraneous extruding force extrusion molding.
The first described shaping dies 2 and the second shaping dies 4 adopt high strength cemented carbide to make, and surface scribbles coating, and the processing life-span is 5-8 ten thousand; Wherein the inner core die wall 41 of the second shaping dies 4 is provided with the spline processing tooth 411 of more than at least two-stage; Described workpiece 1 is hollow bloom or after processing during porose workpiece, pushes core 6 vertically in the hollow hole of now this workpiece 1.
Described pulsed step by step forming technique can significantly reduce spline plastic force, can be used for processing thin-walled class part.And also can be used to processing blind hole internal spline and two-stage with upper spline.Spline stress after processing is little, and heat treatment deformation is stablized.Spline processing length adjustable range is large.The plastic force that pulsed is shaped step by step is smaller, and the spline precision of processing is high, can reach 5 grades of spline accuracy tolerance and form and position tolerance.
Be understandable that, for a person skilled in the art, technical scheme of the present invention and inventive concept be equal to and replace or change the protection domain that all should belong to the claim appended by the present invention.
