Therefore, during the process of entering and exiting the workpiece, the contact area between the cutting edge 22 and the workpiece is gradually changed, and the stress on the section of the arc-shaped groove 11 of the spline housing is uneven, so that the stress of the inner lane 1 of the spline housing is uneven in the shaping process, and the errors of the roughness and the profile degree of the lane are overlarge.
Based on the problem, the embodiment of the invention provides a blade, which solves the problem that the existing spline housing is not uniformly stressed in the process of extrusion shaping of an inner ball channel. Specifically, as shown in fig. 3, the blade 2 of the present embodiment includes a blade body 21 and a blade 22, where a plurality of arc-shaped protrusions 211 are uniformly distributed on the blade body 21, the radius of each arc-shaped protrusion 211 is R, the blade 22 is uniformly distributed on the outer peripheral surface of the blade body 21, that is, the blades 22 are correspondingly disposed on the outer peripheral surface of each arc-shaped protrusion 211, and the blade 22 contacts and extrudes the inner wall of the inner lane 1 in the shaping process, as shown in fig. 4 and fig. 5, the blade 22 includes a blade surface 221, a front corner 224 and a rear corner 225, the front corner 224 and the rear corner 225 make the width a of the blade surface 221 consistent, a first chamfer 222 is disposed outside the front corner 224, and a second chamfer 223 is disposed outside the rear corner 225; the width A of the blade surface 221 is smaller than the width of the cutter body 21, the blade surface 221 is a surface which is in contact extrusion with the inner lane 1 of the workpiece, the blade surface 221 is positioned at the outermost periphery of the arc-shaped protrusion 211, the cross-sectional shapes of the blade 22 in the axial direction are consistent with the tooth shape (6-R) of the workpiece, the blade 2 is in integral contact with the workpiece from entering the workpiece to exiting the workpiece, instead of gradually transiting to the whole blade surface in the initial two-point contact as in the prior art, the contact area of the blade surface 221 and the workpiece is always consistent, the inner lane 1 of the workpiece is stressed uniformly, the shaping process is stable, and the workpiece is not easy to deform or out of tolerance no matter whether the inner lane 1 is an outer circle.
As shown in fig. 3, the edge lines formed by the first corner 222 and the second corner 223 on the arc-shaped protrusion 211 are intersecting lines, while since the front corner 224 changes the edge line of the first corner 222 connected with the edge surface 221 into an arc line, and the rear corner 225 changes the edge line of the second corner 223 connected with the edge surface 221 into an arc line, as shown in fig. 4, the projections of the two edge lines of the edge surface 221 of the present embodiment in the axial direction of the cutter body 21 are two parallel lines, thereby ensuring that the width of the edge surface 221 is always substantially consistent from one end continuous with the cutter body 21 to the other end continuous with the cutter body 21, and further ensuring that the contact area of the edge surface 221 with a workpiece is consistent.

In order to achieve a better guiding effect, in this embodiment, the axial length of the front guiding region 31 is 30% -40% of the overall axial length of the plurality of blades 2, and the axial length of the rear guiding region 33 is 20% -25% of the overall axial length of the plurality of blades 2. Specifically, as shown in fig. 7, the front guide area 31 has 3 blades 2, the press-shaping area 32 has 3 blades 2, and the rear guide area 33 has 2 blades 2; each blade 2 is closely fitted, so that the axial length of the front guide zone 31 is 3/8, i.e. 37.5%, of the overall axial length of all blades 2, and the axial length of the rear guide zone 33 is 2/8, i.e. 25%, of the overall axial length of all blades 2.
In order to facilitate feeding, the diameters D of the cutter bodies 21 of the plurality of blades 2 positioned in the front guide area 31 are gradually increased from front to back and are smaller than the diameters D of the cutter bodies 21 of the blades 2 in the extrusion shaping area 32, so that the inner ball channel 1 of a workpiece is gradually enlarged, and the shaping effect is better; in order to avoid that the edge surface 221 of the rear guiding zone 33 scrapes the shaped inner lane 1 during withdrawal, the diameter D of the cutter body 21 of the cutter blade 2 in the rear guiding zone 33 gradually decreases from front to rear and is smaller than the diameter D of the cutter body 21 of the cutter blade 2 in the extrusion shaping zone 32.
As shown in fig. 6, a through mounting hole 212 is formed in the center of the cutter body 21, the shape of the through mounting hole 212 is matched with the shape of the cutter bar 3, so that the cutter blade 2 is sleeved on the cutter bar 3 and cannot rotate circumferentially, the through mounting hole 212 can be an elliptical hole or other holes, and the cross section of the cutter bar 3 corresponds to the elliptical hole or other holes. The through-mounting hole 212 of this embodiment includes a circular hole 213 and a plurality of positioning portions 214 disposed on an inner wall of the circular hole 213, wherein the positioning portions 214 are positioning grooves or positioning protrusions, when the positioning portions 214 are positioning grooves, the cutter bar 3 is provided with corresponding positioning protrusions, and when the positioning portions 214 are positioning protrusions, the cutter bar 3 is provided with corresponding positioning grooves.
The reason why the main body of the cutter bar 3 is set to be cylindrical is that the plurality of blades 2 of the present embodiment are axially fixed on the cutter bar 3 by tightly fitting, meanwhile, the extrusion push broach of the present embodiment further includes a locking member 4, the blades 2 are sleeved on the cutter bar 3 by penetrating through the mounting hole 212 and are axially fixed by the locking member 4, the locking member 4 is a screw, and is in threaded fit with the cylindrical main body of the cutter bar 3, meanwhile, the rear end of the cutter bar 3 is provided with a positioning step 34, and the locking member 4 and the positioning step 34 clamp the plurality of blades 2 on the cutter bar 3, so that the blades 2 are tightly fitted and fixed with the adjacent blades 2 or the locking member 4 or the positioning step 34. The insert 2 is thus defined circumferentially and axially in the shank 3, being substantially stationary relative to the shank 3, facilitating the truing of the workpiece by the edge face 221.
The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
