Help and keep position of the roller bearing in bearing 9, and provide the connection of roller bearing and bearing to prevent roller bearing relative to bearing along its rotating shaft
It is mobile.Lubricating system also solves wear problem.Reference picture 4A and Fig. 5, the bearing 9 are respectively provided with passage 15 in each end.Such as
Shown in Fig. 7, the passage 15 leads to support 10.Lubricant can be injected into the passage so that it reaches support, to the rolling
Axle 11 provides the abrasion and loss for lubricating and further reducing roller assembly 7.
Reference picture 12, in certain embodiments of the present invention, the roller bearing 11 can at one end or its surface other portions
On position have ditch flute profile mark line 11a so that operator can easily observe it whether as it should it is in use
Rotate.If it is not rotated, operator can impose more lubricants by passage 15, and/or, dismantled to investigate rolling
The reason for axle stops the rotation.
Figure 10 A show that (for convenience of description, some foregoing features are omitted when roller assembly 7 is installed in place
), the contact situation between the work piece 4 and punch die 2.It can see from Figure 10 A, the mould with bearing and roller bearing and not
Mould with bearing and roller bearing, with identical appearance and size (overall dimension).Extra sheet material or tight is not needed
Firmware.The roller bearing extends the length of punch die 2.The roller bearing does not have nose portion.The roller bearing and bearing can be contained in mould
The end of tool.The work piece contact surface provided by roller bearing is similar with the contact surface of common power diel.Figure 10 B
Another embodiment of work piece and punch die 2 is shown, wherein the second of roller assembly 7 embodiment has been installed to
Position.If roller bearing 11 weares and teares over time, it is not necessary to by drift 3 and/or the integral replacing of punch die 2 or to drift 3 and/
Or punch die 2 largely handle to recover its shape, roller bearing 11 is with regard to that can be easily replaced.For example, if it is necessary, not overall
Drift and/or punch die 2 are changed with regard to the entirety of roller assembly 7 can be changed.Optionally, bearing 9 can be retained and only roller bearing 11 is by more
Change.
Roller bearing is changed to can relate to dismantle the roller assembly 7 from drift 3 and/or punch die 2.The dismounting of roller assembly, can
Realized by the way that roller assembly is skidded off from the die cavity of drift 3 and/or punch die 2.It may need to apply certain power, will rolling
Shaft assembly is skidded off from drift 3 and/or punch die 2.Once being disassembled from drift or punch die, new roller bearing 11 can be installed to
Slipped back on roller assembly 7 and by roller assembly in drift 3 or punch die 2.In some cases, institute is not dismantled from power press
The replacing can also be realized by stating drift or punch die.Because the roller assembly 7 can by the way that part is gone out from drift or punch die or
Skid off and then slip into drift or punch die to change by new part, change involved skill seldom.Because need not be skilled
Craftsman, which reduce the cost for changing part.
In addition, drift and/or punch die can be changed, so that the roller bearing and bearing are modified by being installed to punch die or punch die
On.Although it is unpractical that screwed hole is got out in hardened steel drift or punch die, steel wire corroding machine (wire erosion are utilized
Machine the die cavity or slit) cut out for roller bearing and bearing is possible.Steel wire corroding machine was in twentieth century 60 years
In generation, is just developed success, and can be used to cut hardened steel dies.Steel wire corroding machine can cut out type in hardened steel dies
Chamber --- including the die cavity damaged in shoulder regions --- is so that roller assembly is modified by being installed on mould.Steel wire is rotten
The accessible accuracy of erosion machine, it is meant that it is cleavable go out with roller assembly be interference fitted die cavity.Because roller bearing or roller bearing and branch
The combination of seat can be replaced in abrasion, compared to more mold exchange in itself, and remodeling bearing and roller bearing have a clear superiority.In mould
When being just made, the die cavity for roller assembly can be also formed.May be slightly although cutting out die cavity in drift 3 or punch die 2
Reduce the intensity of power diel, still can apply similar maximum pressure per square inch.In a word, pacify in roller assembly
When being attached to, the power needed for work piece shaping will be less than power required during without roller bearing；Because, work piece into
During shape, roller bearing reduces the amount of friction produced between work piece 4 and drift 3 and/or punch die 2.

Roller bearing 11.The need for particular task, they can be made up of the material with different qualities (such as coefficient of friction), and can
It is easily replaced by abrasion.
Based on another embodiment, Figure 13 and Figure 14 show the roller assembly for punch die or drift.In such case
Under, roller bearing 18 is maintained in the support 19 of bearing 20, without using shape of a hoof clip.More precisely, roller bearing 18 via
The holding plate 21 that spiral is fixed on the two ends of support 19 is kept.The dop (stub) 22 at the two ends of roller bearing 18 and 23 points of the hole of holding plate 21
Clamping Pei not merged.When the interior angle of drift or the shoulder of punch die (roller assembly is mounted thereon) is approximately less than 70 degree, roller bearing
This connected mode is particularly useful；In this case, bearing is less than 180 degree around the angle of roller bearing, so can not be by
Its perpendicular positioning.In the embodiment shown in Figure 13 and Figure 13, holding plate provides the approach of connection roller bearing and bearing, to prevent
Only roller bearing had not only been vertically moved relative to bearing but also moved along its rotating shaft.Existed in the manner shown using another benefit of holding plate
In holding plate is only by roller support on bearing.They do not fix roller bearing relative to drift or punch die, it is meant that need not be
Screwed hole is got out in drift or punch die.As it was previously stated, it is uneconomic that screwed hole is got out in hardened steel drift or punch die.Due to
Holding plate is attached on bearing, and this problem just overcomes.Reference picture 15, in some embodiments, diel can make
With drift 23, the drift 23 is moved towards the work piece 24 being arranged on punch die 25, and the punch die 25 does not have die cavity.It is described
Drift 23 has dismountable roller assembly 26, in turn, and the roller assembly 26 has removable as described in other embodiment
Unload roller bearing.Figure 16 and Figure 17 shown when drift 23 is used to shape work piece 24, after the activation stage one by one of phase rush
First 23.
Figure 18 shows an embodiment of mould, and wherein punch die 2 and drift 3 is provided with roller bearing in their shoulder
Component.The friction that the shoulder of the setting of multiple roller assemblies, it is meant that during shaping operation, punch die 2 and drift 3 is subjected to is notable
Less than the friction being subjected to using static punch die and punch shoulder.Roller bearing decreases the cut on the work piece of shaping.
Although describing some preferred embodiments of the present invention by way of example, it should be appreciated that do not departing from appended power
It can modify and improve in the case of the scope that profit is required.
