Description
Technical field
The present invention relates to the frock of a kind of spline cold extrusion press, particularly to the tooth bar frock of a kind of spline cold extrusion press.
Background technology
Spline cold extrusion press be present stage for producing the usual means of spline, it utilizes tooth bar opposing upper and lower to be processed workpiece.Multiple spline gear rolling is that part rotates between the tooth bar moved in the opposite direction by the metal of part edge is carried out continuous profiled one processing technique.Tooth bar uses particular design, makes each tooth be penetrate deep into step by step in part by the slope section of tooth bar, and then, in the finishing section of tooth bar, part ensures size and fineness by rotating a few.
When present stage uses the different number of teeth of spline cold extrusion press processing and modulus spline, need to change different tooth bars, its versatility is poor, and the size of tooth bar is long, weight is big, and the labor intensity changing tooth bar is big, the adjustment time is long, and the manufacturing cost of tooth bar is very big, through extensively retrieval, not yet find ideal technical scheme.
Summary of the invention
The shortcoming that the invention aims to the tooth bar poor universality of solution present stage spline cold extrusion press, and the tooth bar frock of a kind of spline cold extrusion press proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of tooth bar frock of spline cold extrusion press, fixing seat including two corresponding matching, each fixing seat is designed with two corresponding matching wedges, each fixing seat is also connected with a tooth bar respectively, tooth bar is arranged on corresponding wedge, it is characterised in that: be connected between corresponding wedge and tooth bar cushion block.
On the basis of technique scheme, can there is a technical scheme further below:
Also be connected adjustment cushion block in the side of tooth bar.
Described fixing seat, wedge and tooth bar are prior art, its connected mode is all not changed in, this device is processing identical modulus, during the spline of the different numbers of teeth, cushion block need to be added between wedge and tooth bar, adding in the side of tooth bar and adjust cushion block, the thickness of the cushion block of interpolation and adjustment cushion block is according to formula H=(RDLO-φ D)/2-SED and L=(L1+L2)/2 are calculated, wherein:
The upper and lower opening spacing of RDLO machine；The size of SED molding tooth bar initiating terminal；
φ D part diameter before spline molding；The thickness of H cushion block；L1The maximum effectively transverse tooth thickness of spline；L2The actual transverse tooth thickness of spline minimum.
The thickness of tooth bar general with the graininess key of workpiece before journal diameter closely related, adding man-hour, it is allowed to the diameter of workpiece has certain deviation, error can reduced further by regulating micrometer adjusting screw.
It is an advantage of the current invention that: this device is that the frock to multiple spline gear rolling machine is changed a social system, achieve when producing the spline of identical modulus, the different number of teeth, identical spline tooth bar can be used to be processed, enhance the versatility of tooth bar, reduce labor intensity, save the time of toolsetting, reduce equipment cost.
Accompanying drawing explanation
Fig. 1 is the basic structure schematic diagram of the present invention.
Detailed description of the invention
nullAs shown in Figure 1，The tooth bar frock of a kind of spline cold extrusion press that the present invention provides，Fixing seat 1 including two corresponding matching，It is symmetrical arranged two location-plate 1a in the both sides of each fixing seat 1，A baffle plate 1b it is designed with in the upper end of each location-plate，Each fixing seat 1 is designed with two corresponding matching wedges 2，Wedge 2 side contacts cooperation with corresponding location-plate 1a respectively，Location-plate 1a is also associated with micrometer adjusting screw 8，Micrometer adjusting screw 8 coordinates with the contacts side surfaces of following wedge 2，Each fixing seat 1 is also connected with a tooth bar 3 respectively，Fixed plate 3a of tooth bar both sides respectively with corresponding baffle plate 1b corresponding matching，Each tooth bar 3 is arranged on corresponding wedge 2，Each baffle plate 1b is designed with a hold-down bolt 7，Hold-down bolt 7 and fixed plate 3a compression fit，It is also connected with bolt 6 wherein on a baffle plate 1b，Bolt 6 and one of them side location fit of tooth bar 3，Each tooth bar 3 is fixed on fixing seat further through connecting bolt 9，It is characterized in that: the cushion block 4 being connected square between corresponding wedge 2 and tooth bar 3，The side that the two of which of cushion block is relative contacts cooperation with corresponding location-plate 1a respectively，When producing the different number of teeth，The adjustment cushion block 5 that also can also be connected square between tooth bar 3 and location-plate 1a，Adjust cushion block and be arranged on the another side of the tooth bar 3 relative with bolt 6.
Identical at processing modulus, during the different spline of the number of teeth, use same set of molding tooth bar, it is necessary to they are measured, to obtain the thickness H of cushion block.Regulate the computing formula of upper and lower rack position: RDLO=2 × (SED+H)+φ D during according to machine tooling spline and calculate the thickness H=(RDLO-φ D of cushion block)/2-SED,
Wherein, the size of SED tooth bar initiating terminal；The upper and lower opening spacing of RDLO machine, is 6 inches；φ D part diameter before spline molding；The thickness of H cushion block.
Adjust cushion block 5 thickness to determine: check the corresponding product drawing of part, pass through Parameter of spline, it is thus achieved that maximum effectively transverse tooth thickness L of spline1Transverse tooth thickness L actual with spline minimum2, then pad thickness L=(L is adjusted1+L2)/2.
If being changed into even number tooth by odd number gear, then can there is displacement in the first profile of tooth that tooth bar cold extrusion is formed up and down, therefore increase this and adjust cushion block to form the first displacement holding this profile of tooth.If the number of teeth is always odd number gear or even number tooth, then need not increase this and adjust cushion block.After ensureing spline molding, the problem that spline does not misplace, adjust cushion block thickness deviation and must control at [+(L1+L2)/2 ,-(L1+L2)/2].
Operating procedure and method:
A, equipment shut down；
B, unload two pieces of lathe front backplates；
C, unclamp the hold-down bolt of upper and lower tooth bar；
D, unclamp the connecting bolt of upper and lower tooth bar；
E, unclamp the bolt of upper and lower tooth bar；
F, unclamping micrometer adjusting screw, (and lower tooth bar raise) is to the height that be enough to place cushion block between tooth bar and voussoir so that upper rack fall；
G, between tooth bar and voussoir insert cushion block；
H, between tooth bar and side location-plate insert adjust cushion block；
I, tighten the location screw of upper and lower tooth bar；
J, tighten the connecting bolt of upper and lower tooth bar；
K, tighten the hold-down bolt of upper and lower tooth bar；
L, regulation micrometer adjusting screw；
M, open the coolant flowing to tooth bar；
N, load onto two pieces of lathe apron plates.
