The another kind of preferred view that constitutes of Fig. 6 by impact of the present invention or stamping tool.
The specific embodiment
Fig. 1 illustrates in form the view for the cylinder type hollow body of clutch bar 1, can be the automatic gear-box that for example is used for car uses as it.This clutch bar (Kupplungslamellentraeger) 1 has the molding gear portion that its longitudinal axis extends formation that is parallel to.The bottom design of clutch bar 1 is the inner flange 2 that opens wide, and molding gear portion stops to the there of free end face unlimitedly, as from being clear that the longitudinal sectional view by Fig. 2.
Now will the inboard 3 of each tooth top 3 ' on make a retaining wall (wall) 4 that radially inwardly points to, as it can clearly be seen that with fragmentary detail view among Fig. 3 by the longitudinal sectional view of Fig. 2.Described retaining wall 4 should prevent, is in operation to move and therefore this cause the outflow of oil on this direction to the direction of end face vertically at the oil film that forms on the inboard of clutch bar 1.Therefore, described retaining wall also can only have very little radial dimension.
By the present invention suggestion, with impacting or stamping tool, by with a drift 5 outer surface 3 radially from external guidance to the tooth top 3 that is used to rabbet ", form a kind of such retaining wall 4.
Drift 5 has a width by the present invention now, and this width is less than the width b of tooth top 3.That is punching course is not to carry out on the whole width b of tooth top 3, and just carries out on the subregion of described width b.
Thus, by Fig. 4 b) punching course that carries out the inboard 3 of tooth top 3 ' on form a retaining wall 4 as requested like that.On lateral surface, form a little groove or recess 6 by drift 5.By drift 5 advantageously do not process or do not damage the edge of the outer surface of tooth top 3 by size of the present invention, thereby the flank of tooth 7 also has original shape after finishing punching course.
Drift 5 preferably has an outer surface 3 with respect to tooth top 3 " acutangulate, along the working face 5 of the longitudinal direction orientation of clutch bar 1, as particularly from Fig. 4 longitudinal sectional view a), learning.Advantageously making one thus has towards the retaining wall of the clutch bar 1 inboard flank of tooth that tilts to rise.The width of preferred drift 5 is selected in this wise, makes just in time to form a retaining wall width of the inner surface of the tooth top 3 between the flank of tooth of these two inside of retaining wall leap.
Especially for the thin wall thickness of clutch bar 1 or very wide tooth top 3, advantageously can use a drift 8 as stamping tool, this stamping tool except itself punching press or working face 8 ' have the clamping face 9 that stretches out along operative orientation from working face in the side, as from Fig. 5 finds out a).This working face 8 ' and clamping face 9 advantageously make whole.Alternatively, working face 8 ' also can make particularly by a kind of independent material, and removably or regularly be connected with the matrix of clamping face.
Therefore, a kind of such stamping tool prevents that the material of tooth top 3 is displaced sideways or squeezes, and be used for optimally keeping the planform of the tooth top 3 of being correlated with thus, wherein clamping face 9 is as the cooperation clamper effect with respect to drift 8, and the material that only allows tooth top 3 inside radially moves with respect to the longitudinal axis of clutch bar 1.This instrument for example is suitable for the situation of relatively thin wall thickness or wide tooth top 3 particularly well.
Schematically illustrate by the another kind of selectable scheme of stamping tool of the present invention longitudinal sectional view by Fig. 6.At this, can move mutually individually as the drift 8 of stamping tool with as the clamping face 9 that cooperates clamper 10.Therefore cooperate clamper 10 at first to come on the tooth top 3, and drift 8 just lean on the end face of tooth top 3 on punching press ground afterwards.
Advantageously, punching course carries out each independent tooth top 3 in order individually, that is clutch bar 1 is correspondingly progressively around its longitudinal axis rotation, and processing is carried out on a station.
Be contemplated that also that in addition two or more punching courses carry out simultaneously in parallel to each other, and the clutch bar has rotated through the tooth top 3 of respective numbers during this period.
The driving of stamping tool is for example machinery or hydraulically realization in known manner.When mechanical type drives, realize the regularity preferably and the precision of the structure of retaining wall 4 usually.
