Definitions

the present invention relates to a mould which is designed to be applied for the purpose of a blanking process in which a transverse element which is designed to be part of a push belt for a continuously variable transmission is blanked out of basic material.
a push belt for a continuously variable transmission is generally known.
a push belt comprises two endless, ribbon-like carriers shaped like a closed loop for carrying a relatively large number of transverse elements.
the transverse elements are movably arranged along the entire circumference of the carriers, wherein, during operation, they are able to transmit forces which are related to a movement of the push belt.
a longitudinal direction of the transverse element corresponds to a circumferential direction of the push belt.
a vertical transverse direction of the transverse element corresponds to a radial direction of the push belt.
a horizontal transverse direction of the transverse element corresponds to a direction perpendicular to both the longitudinal direction and the vertical transverse direction.
the transverse element In the horizontal transverse direction, on opposite sides, the transverse element is provided with recesses for receiving the carriers.
the transverse element comprises carrying surfaces.
the transverse element In the horizontal transverse direction, on opposite sides, for the purpose of contact between the transverse element and pulley sheaves of a pulley of a continuously variable transmission, the transverse element is provided with pulley sheave contact surfaces, which are divergent in the direction of the carrying surfaces.
top and “bottom”, which are hereinafter applied, are related to the direction of divergence; this is defined as being from bottom to top.
the transverse element comprises successively a basic portion, a neck portion and a top portion, wherein, in the horizontal transverse direction, the dimensions of the neck portion are relatively small.
the basic portion comprises the carrying surfaces and the pulley sheave contact surfaces.
the basic portion is located at the side of the inner circumference of the push belt, whereas the top portion is located at the side of the outer circumference of the push belt.
the top portion comprises two retaining surfaces which are located opposite to the carrying surfaces.
the transverse element has two main body surfaces, namely a front surface and a back surface, which extend substantially parallel with respect to each other, substantially perpendicular to the longitudinal direction. At least a portion of the front surface of the transverse element is designed to contact at least a part of the back surface of a subsequent transverse element in the push belt, whereas at least a part of the back surface of the transverse element is designed to contact at least a part of the front surface of a previous transverse element in the push belt.
a circumferential surface, of which the carrying surfaces and the pulley sheave contact surfaces are part, extends between the two main body surfaces. In the longitudinal direction of the transverse element, a dimension of the circumferential surface is relatively small.
the transverse element is manufactured out of basic material shaped like a sheet.
a cutting member and a supporting member are applied, wherein the cutting member is designed to cut the transverse element out of the basic material under the influence of a cutting force, and wherein the supporting member is designed to support the transverse element by a supporting force during the blanking process.
the circumference of both the supporting surface and the cutting surface is substantially equal to the circumference of the transverse element.
the cutting member penetrates the basic material under the influence of pressure, wherein a mutual movement of transverse element to be blanked and the basic material is allowed. At that moment, the transverse element to be blanked is clamped between the cutting member and the supporting member.
a mould is applied, which is provided with a receiving space for receiving the transverse element to be blanked, the supporting member and an end of the cutting member.
the inner circumference of the receiving space substantially corresponds to the circumference of the cutting member, the supporting member, as well as the transverse element to be blanked, so that the receiving space is capable of receiving the transverse element to be blanked, practically without any play.
the transverse element has a basic portion and a top portion, which are connected to each other via a relatively narrow neck portion. Due to the fact that the transverse element is manufactured by means of a blanking process as described above, limitations apply to the design of the transverse element having the said portions. For example, a value of a relation between dimensions of the basic portion and dimensions of the top portion needs to be within a certain range. When, for instance, the top portion is relatively too small, there is a chance that the cutting member breaks during the blanking process. Also, a distance between a carrying surface and an opposite retaining surface needs to be larger than a certain minimum distance.
EP-A-1539395 discloses a divided mould used for blanking transverse elements for push belts. This document falls under Article 54(3) EPC.
each mould component comprises a portion of an inner surface of the receiving space.
the manufacturing process of the mould is simplified.
advanced techniques such as wire sparking need to be applied for the purpose of forming the receiving space in the mould.
at least a portion of the inner surface of the receiving space is provided with a coating, in order to obtain a desired quality of the surface or to prolong the tool life of the mould, for example.
Applying the coating in the receiving space having an inner circumference which substantially corresponds to the circumference of the transverse element is a cumbersome process.
the fact that the mould has a certain height, among other things for the purpose of being capable of accommodating the supporting member plays a role, because, as a consequence, at some places of the inner surface of the receiving space, narrow channels are present, as it were.
the mould components are separately formed, wherein more conventional techniques may be applied. This is related to the general fact that it is easier to accurately shape an outer surface of an arbitrary element than an inner surface of a space in an arbitrary element. As far as coating is concerned, it is also true that it is easier to coat an outer surface of an arbitrary element than an inner surface of a space in an arbitrary element. Therefore, it is strongly preferred to coat the mould components previous to composing the mould by joining the mould components.
the application of separate mould components allows for performing maintenance of the mould in a more goal-oriented manner.
this relief is worn out, it needs to be provided again, for example by means of grinding, unless the extent to which the relief is worn out is above a certain upper limit.
the relief is present on two separate mould components, which may each be removed and processed when the relief is worn out.
separate mould components it is also possible to only replace components when necessary. According to the state of the art, in case a portion of the inner surface of the receiving space gets obsolete, it is necessary to replace or process the entire mould, which is more expensive than replacing or processing a few mould components.
the division of the mould in mould components offers the possibility of manufacturing different mould components from different materials. Because the required surface quality of the circumferential surface of the transverse element is different for different portions of the circumferential surface, it is not necessary that all mould components have the same surface quality. Therefore, it is also not necessary that all mould components are manufactured from the same material. For example, in the case of mould components which are allowed to have a relatively low surface quality, a cheaper material may be applied than in the case of mould components which need to have a relatively high surface quality. It is also an option to provide at least a portion of mould components which, as a consequence of their application during the blanking process, wear out at the highest pace with wear-resistant material, which is usually relatively expensive.
Figure 1 diagrammatically shows a continuously variable transmission, such as for utilization in a motor vehicle.
the continuously variable transmission is indicated in general by the reference sign 1.
the continuously variable transmission 1 comprises two pulleys 4, 5 being arranged on separate pulley shafts 2, 3.
An endless push belt 6 being shaped like a closed loop is arranged around the pulleys 4, 5, and serves for transmitting torque between the pulley shafts 2, 3.
Each of the pulleys 4, 5 comprises two pulley sheaves, wherein the push belt 6 is positioned and clamped between said two pulley sheaves, so that with the help of friction a force may be transmitted between the pulleys 4, 5 and the push belt 6.
the push belt 6 comprises two endless carriers 7, which are usually composed of a number of rings.
transverse elements 10 are arranged, wherein the transverse elements 10 are mutually adjacent to each other and are moveable with respect to the carrier 7 in the circumferential direction.
the transverse elements 10 are shown in figure 1 .
FIGS 2 and 3 show a transverse element 10.
a front surface of the transverse element 10 is indicated in general by the reference sign 11, whereas a back surface of the transverse element 10 is indicated in general by the reference sign 12.
both the front surface 11 and the back surface 12 are also indicated as main body surface 11, 12.
a circumferential surface 19 extends between the main body surfaces 11, 12.
the transverse element 10 comprises successively a basic portion 13, a relatively narrow neck portion 14, and a top portion 15 shaped like the tip of an arrow.
the basic portion 13 is located at the side of the inner circumference of the push belt 6, whereas the top portion 15 is located at the side of the outer circumference of the push belt 6.
at least a portion of the front surface 11 of the transverse element 10 contacts at least a portion of the back surface 12 of a subsequent transverse element 10
at least a portion of the back surface 12 of the transverse element 10 contacts against at least a portion of the front surface 11 of a preceding transverse element 10.
the basic portion 13 of the transverse element 10 as shown in figure 2 comprises two carrying surfaces 16 which serve for supporting two carriers 7. Furthermore, the basic portion 13 comprises two pulley sheave contact surfaces 17.
the transverse element 10 moves over the pulley 4, 5, contact between the transverse element 10 and contact surfaces of the pulley sheaves is realized through said pulley sheave contact surfaces 17.
a bottom surface 18 extends between the pulley sheave contact surfaces 17.
the carrying surfaces 16, the pulley sheave contact surfaces 17, as well as the bottom surface 18 are part of the circumferential surface 19.
the top portion 15 comprises two retaining surfaces 23 which are located opposite to the carrying surfaces 16.
a position of the carriers 7 in the radial direction is delimited by the carrying surfaces 16 on the one hand, and by the retaining surfaces 23 on the other hand.
the top portion 15 comprises two top surfaces 24 which are connected to each other. At an end, each of the top surfaces 24 is connected to a retaining surface 23 of the top portion 15. Both the retaining surfaces 23 and the top surfaces 24 are part of the circumferential surface 19.
FIG 4 a blanking area of a blanking device 60 and basic material 50 being placed in there are diagrammatically depicted.
the blanking device 60 comprises a cutting member 30 which is designed to cut the transverse element 10 out of the basic material 50.
the cutting member 30 is accommodated in a guiding space 36 in a guiding plate 35, an important function of which is guiding the cutting member 30 during a blanking movement.
a supporting member 40 is in line with the cutting member 30, which is designed to support the transverse element 10 during the blanking process.
the circumference of both the cutting member 30 and the supporting member 40 substantially corresponds to the circumference of the transverse element 10 to be blanked.
the supporting member 40 is accommodated in a receiving space 46 in a mould 45, an important function of which is guiding the cutting member 30, the supporting member 40, as well as the transverse element 10 during a blanking movement.
the inner circumference of the receiving space 46 substantially corresponds to the circumference of the cutting member 30, the supporting member 40, as well as the transverse element 10.
the basic material 50 is located between the cutting member 30 and the guiding plate 35 on the one hand, and the supporting member 40 and the mould 45 on the other hand.
a portion of the basic material 50 which is located between the cutting member 30 and the supporting member 40 is destined to form the transverse element 10, and will hereinafter be referred to as blanking portion 51.
Another portion of the basic material 50 namely the portion that is located between the guiding plate 35 and the mould 45, will hereinafter be referred to as rest portion 52.
the mould 45 comprises a mould surface 47, an important function of which is supporting the rest portion 52 of the basic material 50.
An inner surface 48 of the receiving space 46 of the mould 45 is connected to the mould surface 47.
a first stage or initial stage as diagrammatically shown in figure 5a , the blanking portion 51 of the basic material 50 is clamped between the cutting member 30 and the supporting member 40, while a rest portion 52 is clamped between a guiding surface 37 of the guiding plate 35 and the mould surface 47 of the mould 45.
the clamping forces act in a direction substantially perpendicular to the guiding surface 37 and the mould surface 47.
a fourth stage as diagrammatically shown in figure 5d , as a result of the mutual movement of the guiding plate 35 and the cutting member 30 on the one hand, and the mould 45 and the supporting member 40 on the other hand, the rest portion 52 has been put to a position at a distance from the mould surface 47. In this position, the rest portion 52 can be removed. Furthermore, the supporting member 40 has been moved with respect to the mould 45 in such a way that the blanking portion 51 has been put to a position above the level of the mould surface 47, so that the blanking portion 51 can be removed as well. In the process, the supporting member 40 may function as pushing member.
Figure 6 shows a top view of a mould 70 according to a first preferred embodiment of the present invention.
this mould 70 will hereinafter be referred to as first mould 70.
the first mould 70 has a receiving space 46 for receiving, among other things, the transverse element 10 to be blanked.
the first mould 70 comprises a number of separate mould components for delimiting the receiving space 46.
the first mould 70 comprises three mould components. For each of these three mould components, it is true that a portion of the surface thereof is part of the inner surface 48 of the receiving space 46. Said portion of the surface of the mould components will hereinafter be referred to as transverse element contact surface.
a first mould component will hereinafter be referred to as main component 71.
the transverse element contact surface of this main component 71 is designed to contact, during the blanking process, both pulley sheave contact surfaces 17, the bottom surface 18 and both top surfaces 24 of the transverse element 10 to be blanked.
a second mould component and a third mould component will hereinafter be referred to as middle components, wherein one of the middle components is indicated by reference sign 72a in figure 6 , whereas another of the middle components is indicated by reference sign 72b in figure 6 .
the transverse element contact surface of the middle components 72a, 72b is designed to contact, during the blanking process, a portion of the circumferential surface 19 of the transverse element 10 to be blanked, which extends from a transition surface between a pulley sheave contact surface 17 and a carrying surface 16 toward a transition surface between a retaining surface 23 and a top surface 24, at one side of the transverse element 10 to be blanked.
Both the second mould component 72a and the third mould component 72b are provided with a projection (not shown) or the like, in order to prevent a situation in which the mould component 72a, 72b is capable of moving along with a transverse element 10 that is pushed from the receiving space 46 by the supporting member 40.
the projection is positioned such that it contacts a bottom surface of the main component 71, and is not capable of moving beyond that surface, wherein the term "bottom surface” is used to indicate a surface which is located at another side of the mould 70 than the mould surface 47.
the circumferential surface 19 of the transverse element 10 is shaped particularly by the inner surface 48 of the first mould 70.
portions of the circumferential surface 19 which can come into contact with the carriers 7 of the push belt 6 have a good surface quality. These portions comprise the carrying surfaces 16 and the retaining surfaces 23. In case the surface quality of the portions would be insufficient, damage of a carrier 7 might occur, which may eventually lead to breakage of the carrier 7.
the surface quality is related to the roughness of the surface in question. In general, it is true that the rougher the surface, the lower the surface quality.
the middle components 72a, 72b are designed to contact the portions of the circumferential surface 19 of the transverse element 10, mentioned in the preceding paragraph. Consequently, the surface quality of the transverse element contact surface of the middle components 72a, 72b needs to meet higher requirements than the surface quality of the transverse element contact surface of the main component 71. It is also important that the occurrence of adhesion phenomena between the transverse element contact surface of the middle components 72a, 72b and the circumferential surface 19 of the transverse element 10 is limited as much as possible during the blanking process. For example, these conditions may be met by choosing a high-quality material such as hard metal for the middle components 72a, 72b. Another material which meets the conditions is high-speed steel.
the transverse element contact surface of the middle components 72a, 72b is provided with a coating.
the middle components 72a, 72b comprising high-speed steel, it is even preferred to apply a coating to the middle components 72a, 72b.
the main component 71 comprises high-speed steel.
the transverse element contact surface of the main component 71 may be provided with a coating, for example the coating titanium nitrate (TiN), which is known in practice.
TiN titanium nitrate
the middle components 72a, 72b may comprise the same material as the main component 71, but may also comprise hard metal, for example. In view of the cutting quality, the latter option is advantageous.
the division of the first mould 70 in components and the associated positioning of the seams between the components is therefore chosen such that the possible bulges can not be formed on the carrying surfaces 16, the pulley sheave contact surfaces 17 or the retaining surfaces 23, but can only be formed on transition surfaces extending between a carrying surface 16 and a pulley sheave contact surface 17, and on portions of the circumferential surface 19 comprising both a top surface 24 and a transition surface extending between a retaining surface 23 and a top surface 24.
damage of the carrying surfaces 16, the pulley sheave contact surfaces 17 and the retaining surfaces 23 as a result of the removal of the bulges during final processing of the transverse element 10 is prevented.
FIG. 7 shows a top view of a mould 80 according to a second preferred embodiment of the present invention.
this mould 80 will hereinafter be referred to as second mould 80.
the second mould 80 comprises two extra mould components, which will hereinafter be referred to as side basis components.
One of the side basis components is indicated by reference numeral 73a in figure 7
another of the side basis components is indicated by reference numeral 73b in figure 7 .
the transverse element contact surface of each of these side basis components 73a, 73b is designed to contact, during the blanking process, a pulley sheave contact surface 17 of the transverse element 10 to be formed.
seams which are present between the main component 71 and the side basis components 73a, 73b extend from portions of the inner surface 48 of the receiving space 46 of the second mould 80 which are designed to contact, during the blanking process, portions of the circumferential surface 19 of the transverse element 10 comprising both a transition surface between a pulley sheave contact surface 17 and the bottom surface 18 and a portion of said bottom surface 18.
portions of the circumferential surface 19 of the transverse element 10 comprising both a transition surface between a pulley sheave contact surface 17 and the bottom surface 18 and a portion of said bottom surface 18.
the pulley sheave contact surfaces 17 of the transverse element 10 are in contact with pulley sheaves of a pulley 4, 5.
the pulley sheave contact surfaces 17 are provided with a relief having minuscule bulges. This relief is formed on the pulley sheave contact surfaces 17 when the transverse element 10 is moved in the receiving space 46 of the mould 70, 80 during the blanking process.
portions of the inner surface 48 of the receiving space 46 of the mould 70, 80 which are designed to contact the pulley sheave contact surfaces 17 during the blanking process are provided with a relief that is suitable for realizing the desired relief on the pulley sheave contact surfaces 17.
the relief on the inner surface 48 of the receiving space 46 is worn out, it may be provided again, for example by means of grinding, unless the extent to which the relief is worn out is above a certain upper limit.
the relief is present on the transverse element contact surfaces of the side basis components 73a, 73b. Therefore, in the case of wear, it is very easy to provide the relief again.
the only steps which need to be taken for that purpose are removing the side basis components 73a, 73b, providing the relief in the transverse element contact surfaces of these components 73a, 73b again, and putting these components 73a, 73b back in place. If so desired, the worn out set of side basis components 73a, 73b can be replaced by a new set of side basis components 73a, 73b, so that the second mould 80 is instantly fit again to be applied for the purpose of a blanking process. When a durable material such as hard metal is applied for the side basis components 73a, 73b, the wearing process of the relief on the transverse element contact surfaces of the side basis components 73a, 73b will take place at a lower pace.
the mould 70, 80 may be divided in different mould components 71, 72a, 72b, 73a, 73b in any suitable way, wherein the number of mould components may be chosen freely. It is important that the mould components 71, 72a, 72b, 73a, 73b are capable of jointly delimiting a receiving space 46, wherein transverse element contact surfaces of the mould components 71, 72a, 72b, 73a, 73b are shaped such that an inner circumference of the receiving space 46 substantially corresponds to a circumference of the transverse element 10 to be formed.
the manufacturing process of the mould 70, 80 having the mould components 71, 72a, 72b, 73a, 73b is simple, because in the latter case, the relatively complex shape of the receiving space 46 is obtained by simply positioning the mould components 71, 72a, 72b, 73a, 73b with respect to each other in the proper way.
