Abstract

  In a blanking operation in which a transverse element used in a push belt for a continuously variable transmission is punched from a base material, a hole forming member that forms a hole in the surface of the transverse element to be punched is used. The hole forming member is accommodated in a hole 32 in another member used for blanking. The surface of the cutting member and the surface of the hole forming member are intimately joined except at least one region in the recess provided in at least one of the surface of the cutting member and the surface of the hole forming member. This removes oil from the area between the hole-forming member and the transverse element to be formed during the blanking process, thereby leaving unintended marks on the material of the transverse element under the influence of the oil in that area. Is prevented from being formed. This has the important advantage that the displacement of the dimension and shape of the hole can be prevented.

Description

  The present invention relates to a blanking assembly used in a blanking process for punching a transverse element used in a push belt for a continuously variable transmission from a base member. The blanking assembly has a peripheral shape corresponding to the peripheral shape of the transverse element to be punched and has a blanking member provided with a hole, and a hole provided so as to extend into the hole provided in the blanking member. And a forming member. In addition, the hole forming member is designed to be pressed against the surface of the transverse element to be punched, and thereby, a recess is formed on the surface. Further, the inner surface of the hole of the blanking member and the surface of the hole forming member are closely joined.

  The present invention further provides a blanking device to which the blanking assembly is applied, and a push belt transverse element for a continuously variable transmission in which the blanking assembly is used to punch the transverse element from a base member. The present invention relates to a method, a transverse element manufactured using the method, and a push belt having a number of such transverse elements.

  Push belts for continuously variable transmissions are generally well known. Such push belts typically have two endless ribbon carriers formed like a closed loop carrying a relatively large number of transverse elements. The transverse element is arranged along the entire circumference of the carrier and transmits a force linked to the movement of the push belt during the operation of the continuously variable transmission.

  In the following description of the transverse element, the direction described is in the state where the transverse element is part of the push belt. The longitudinal direction of the transverse element corresponds to the circumferential direction of the push belt. The vertical lateral direction of the transverse element corresponds to the radial direction of the push belt. The horizontal lateral direction of the transverse element corresponds to both the longitudinal direction and the vertical lateral direction.

  The transverse element has a first body surface and a second body surface, the first body surface and the second body surface extending substantially parallel to each other and substantially perpendicular to the longitudinal direction. The contours of these two body surfaces are substantially the same, but the reliefs provided on each body surface are different. At least a portion of the first body surface of the transverse element is provided to contact at least a portion of the second body surface of the adjacent transverse element on the push belt. Also, at least a portion of the second body surface of the transverse element is provided to contact at least a portion of the first body surface of another adjacent transverse element in the push belt. A peripheral surface having a relatively small longitudinal dimension is provided to extend between the two body surfaces.

  The two parts of the circumferential surface of the transverse element are designed to function as a support surface that supports the carrier of the push belt. These support surfaces extend on the same basis. Two other portions of the circumferential surface of the transverse element are designed to serve as contact surfaces for contacting the transverse element and the sheave of the continuously variable transmission pulley. The sheave sheave contact surfaces extend at an angle with respect to each other, and the surfaces diverge as they approach the support surface. The terms “top” and “bottom” described below relate to the direction of the branch, and the direction of the branch is defined to be from bottom to top.

  The transverse element has a base part, a neck part, and an upper part continuously from the lower part to the upper part in the vertical transverse direction, and the horizontal dimension of the neck part is set to be relatively small. The base portion is provided with a support surface and a sheave sheave contact surface. In the push belt, the base portion is disposed on the inner peripheral side of the push belt, and the upper portion is disposed on the outer peripheral side of the push belt.

  One of the main body surfaces of the transverse element is provided with a protrusion, and the other of the main body surfaces is provided with a recessed portion, hereinafter referred to as a hole. The positions of the protrusion and the hole correspond to each other, and the protrusion and the hole are usually disposed in the upper part. In the push belt, in any transverse element, the protrusion is provided so as to be located at least partially in the hole of the adjacent transverse element, so that the transverse elements are arranged in a plane perpendicular to the circumferential direction of the push belt. Deviation is prevented.

  The transverse element is manufactured from a sheet-like base material by a blanking process. This blanking process is particularly called a fine blanking process using two blanking members, a cutting member and a support member. The cutting member is designed to cut the transverse element from the base material with a cutting force, and the support member is designed to support the transverse element with a supporting force during the blanking process. During the blanking process, pressure is applied to the cutting member to penetrate the base material. At this time, the punched transverse element and the base material move relative to each other. In this way, the transverse element is completely separated from the peripheral part of the base material.

  Similar to the transverse elements to be punched out, the base part, the neck part and the upper part are distinguished in both the cutting member and the support member. The outer peripheries of both the cutting member and the support member substantially coincide with the desired outer perimeter of the transverse element.

  Another member is provided for forming a hole in the transverse element. A hole is provided in one of the blanking members, and a member for forming a hole is accommodated in the hole. During the blanking operation, in order to ensure that the hole forming member is properly guided by the blanking member, the inner surface of the hole of the blanking member and the surface of the hole forming member are closely joined. Hereinafter, the blanking member and the hole forming member accommodated in the blanking member are referred to as a blanking member.

  In previously known embodiments of blanking assemblies, the hole forming member is arranged to move within a blanking member which is a cutting member. During the known transverse element blanking process, the formation of a hole in the body surface of the transverse element is initiated after the blanking member in which the hole forming member is placed contacts the body surface. This is achieved by configuring the cutting member and the hole forming member to perform a blanking operation with respect to each other so that the hole forming member protrudes with respect to the cutting member. The main body surface of the transverse element from which the hole forming member is punched is pushed from one side, whereby a hole is formed on the main body surface. As already mentioned, since the longitudinal dimension of the transverse element to be punched is relatively small, treatment of one body surface can cause deformation of the other body surface, with respect to this other body surface. A protrusion is formed on the surface of the other main body in a protruding shape.

  It is important that the formation of protrusions and holes in the transverse element takes place in a very accurate and defined manner. A slight deviation in the dimensions of the transverse elements can cause malfunction of the push belt with these transverse elements, or in any case leads to a deterioration of the function of the push belt. During operation of the push belt, as the transverse element moves over the pulley of the continuously variable transmission in which the push belt is used, the transverse element is forced along the circumference of the pulley. At this time, the transverse element moves slightly in the direction away. In all situations, and therefore even when moving over the pulley, the play between adjacent transverse elements must be within predetermined limits, so that the transverse elements always stay in a straight line in an appropriate manner and Follow each other in an appropriate manner.

  However, in practice, although the blanking processing parameters including the size and shape of the hole forming member and the pressure applied to the hole forming member are accurately determined, the predetermined hole, i.e., is set. A hole that deviates from a predetermined shape that is larger and arbitrarily defined than the theoretical hole that is formed based on the parameters is formed.

  An object of this invention is to provide the countermeasure which brings about the result that a predetermined | prescribed hole part becomes a thing approximated enough.

  The above object is achieved by providing the blanking member described above, that is, having a blanking member and a hole forming member, and providing at least one recess in at least one of the surfaces of these members, This is accomplished by providing a blanking assembly characterized in that intimate contact between surfaces is prevented at the location of the recess.

  At the root of the present invention is insight into the blanking process, i.e. the displacement of the hole is due to the small amount of oil present between the hole forming member and the transverse element punched during the blanking process. There is insight. In the blanking process, blanking oil is poured into a base member surrounded by other components in order to prevent wear of a blanking tool used in the process. However, when the hole forming member is pressed against the base member, a small amount of oil is trapped, causing additional pressing on the base member. According to the present invention, oil is removed from between the hole forming member and the base member.

  In particular, in the present invention, intimate contact between the surface of the hole forming member and the surface of the blanking member in which the hole forming member is accommodated is prevented at least in one place, so that the oil is To flow into. This is achieved by providing a recess in at least one of the surfaces. In this case, the oil is prevented from leaving a mark on the surface to be formed. This is achieved by ensuring a path through which the oil existing between the hole forming member and the formed transverse element flows into the space located in the recess when the pressure increases. Inevitably, the recesses need to be arranged so that the oil can reach there. In other words, it is necessary to provide a path for oil to flow from the region between the transverse element to be punched and the hole forming member to the space located in the recess between the transverse element and the hole forming member. In addition, this space needs to be directly connected to a region between the hole forming member and the transverse element to be punched.

  In the scope of the present invention, at least one recess is actually provided in at least one of the surface of the hole forming member provided separately and the surface of the blanking member in which the hole forming member extends. Various embodiments are included. In one embodiment, at least one elongated groove is provided on the inner surface of the hole in the blanking member. Preferably, the elongated groove is provided so as to extend in the same direction as the direction in which the blanking operation is performed, whereby the space at the position of the elongated groove between the hole forming member and the blanking member. Oil flows easily. This achieves the desire to quickly remove oil on the one hand and the desire to maintain the accuracy required to accurately place the hole forming member in the blanking member on the other hand. In configuring the blanking member and the hole forming member to move relative to each other, these members need to be configured to guide each other with some degree of accuracy as they move. These factors are important in determining that the position and size of at least one recess provided in the surface of the blanking member and / or hole forming member is appropriate.

  Typically, the hole forming member has a substantially circular cross section and thus has a curved surface. According to another embodiment, at least one recess is actually provided in at least one of the surface of the hole forming member provided separately and the surface of the blanking member in which the hole forming member extends. In the bent surface of the hole forming member, at least one region along the bent surface is flat.

A series of blanking operations are shown. A series of blanking operations are shown. A series of blanking operations are shown. A series of blanking operations are shown. A series of blanking operations are shown. 1 schematically shows a cutting member according to the invention. The hole part formation member which concerns on this invention is shown. FIG. 11 is another schematic view of the hole forming member shown in FIG. 10 and shows only one end portion of the hole forming member.

  The present invention will be described based on preferred embodiments of the present invention described below with reference to the drawings. Like reference numerals in the drawings denote like or similar components.

  FIG. 1 schematically shows a continuously variable transmission particularly suitable for use in a motor vehicle. The continuously variable transmission is denoted by reference numeral 1 throughout.

  The continuously variable transmission 1 is provided with two pulleys 4 and 5 arranged on separate pulley shafts 2 and 3. An endless push belt 6 having a closed loop shape is arranged around the pulleys 4, 5 and serves to transmit torque between the pulley shafts 2, 3. Each of the pulleys 4 and 5 has two sheaves, and the push belt 6 is disposed and clamped between the two sheaves so that a force is generated between the pulleys 4 and 5 and the push belt 6 due to friction. Reportedly.

  The push belt 6 has at least one endless carrier 7 which is usually composed of a plurality of rings. A plurality of transverse elements 10 are arranged along the entire length of the carrier 7, and the transverse elements 10 are close to each other and movable in the circumferential direction with respect to the carrier 7. For simplicity, only some of these transverse elements 10 are shown in FIG. Both the carrier 7 and the transverse element 10 are made of metal.

  2 and 3 show the transverse element 10. The first body surface of the transverse element 10 is generally designated 11 and the second body surface of the transverse element 10 is generally designated 12. The body surfaces 11, 12 extend generally perpendicular to the longitudinal direction of the transverse element 10. The peripheral surface 13 is located between the main body surfaces 11 and 12.

  In the vertical lateral direction, the transverse element 10 has a base part 14, a relatively narrow neck part 15 and an upper part 16 provided continuously. In the push belt 6, the base portion 14 is disposed on the inner peripheral side of the push belt 6, and the upper portion 15 is disposed on the outer peripheral side of the push belt 6. Further, in the push belt 6, at least a portion of the first body surface 11 of the transverse element 10 contacts at least a portion of the second body surface 12 of the adjacent transverse element, and at least a portion of the second body surface 12 of the transverse element 10 is Abut at least a portion of the first body surface 11 of another adjacent transverse element. The base part 14 of the transverse element shown in FIG. 2 is provided with two support surfaces 17 that support the two carriers 7 of the push belt 6 at the transition to the neck part 15. Furthermore, two sheave contact surfaces 18 are provided on the base portion 14. When the transverse element 10 moves above the pulleys 4 and 5 of the continuously variable transmission 1, the transverse element 10 and the sheave contact surface of the pulleys 4 and 5 come into contact via the sheave contact surface 18. Both the support surface 17 and the sheave contact surface 18 are part of the peripheral surface 13.

  The upper portion 16 is provided with two holding surfaces 19 that are part of the peripheral surface 13 and are located on the side facing the support surface 17. When the transverse element 10 is arranged on the push belt 6, the space in which the carrier 7 is arranged is defined in the radial direction by a support surface 17 on one side and a holding surface 19 on the other side.

  The first body surface 11 of the transverse element 10 has a protrusion 21. In the example shown, the protrusion 21 is disposed on the upper portion 16 and corresponds to the hole 22 in the second body surface 12. In the push belt 6, the protrusion 21 of the transverse element 10 is disposed in the hole 22 of the transverse element 10 at least a part of which is close to. The protrusions 21 and the corresponding hole portions 22 serve to prevent mutual displacement of the adjacent transverse elements 10 in a plane perpendicular to the circumferential direction of the push belt 6.

  In particular, the transverse element 10 is manufactured by a blanking process called a fine blanking process using the cutting member 30 and the support member 40. The cutting member 30 separates the transverse element 10 from the sheet-like base material 50 during the blanking process, and the support member 40 supports the transverse element 10 during the blanking process. The surface of the base material 50 may be perfectly flat, but this is not necessarily so. A stepped base material 50 may be used.

  The blanking surface 31 of the cutting member 30, ie the surface 31 of the cutting member 30 pressed against the base material 50 during the blanking process, the outer circumference in the part forming the body surface 11, 12 of the transverse element 10 to be punched is traversed. It almost coincides with the outer periphery of the element 10. The same applies to the blanking surface 41 of the support member 40. Accordingly, as in the case of the transverse element 10, the cutting member 30 and the support member 40 are provided so that the base portion, the relatively narrow neck portion, and the upper portion are distinguished. In the following description regarding the cutting member 30 and the support member 40, the longitudinal direction corresponds to a direction perpendicular to the blanking surfaces 31 and 41.

  Hereinafter, blanking processing of the transverse element 10 which is known per se will be described with reference to FIGS.

  4 to 8 schematically show a blanking region of the blanking device and a sheet-like base material arranged in the blanking region. The blanking device has both the cutting member 30 and the support member 40, and the cutting member 30 is accommodated in the guide space 61 in the guide block 62. The guide space 61 has an important function of guiding the cutting member 30 during the blanking operation. The support member 40 is disposed in the same row as the cutting member 30 and is accommodated in the accommodation space 63 of the mold 64. The receiving space 63 has an important function of guiding both the support member 40 and the transverse element 10 during the blanking operation. The inner periphery of the accommodation space 63 substantially coincides with the outer periphery of the breaker member 30, the support member 40, and the transverse element 10. First, the base material 50 is disposed between the cutting member 30 and the guide block 62 on one side and the supporting member 40 and the mold 64 on the other side. The transverse element 10 is formed by a portion of the base material 50 between the cutting member 30 and the support member 40, and this portion is hereinafter referred to as a blanking portion 51. The other part of the base material, that is, the part located between the guide block 62 and the mold 64 will be referred to as the remaining part 52 hereinafter.

  The cutting member 30 has a hole 32, the member 33 is disposed in the hole 32, and the surface 34 of the member 33 is intimately joined to the inner surface 35 of the hole 32. Further, a recessed portion 42 is provided in a portion of the blanking surface 41 of the support member 40 corresponding to the position of the member 33 located in the hole 32 of the cutting member 30. During the blanking operation, the recessed portion 42 of the blanking surface 41 of the support member 40 and the member 33 located in the hole 32 of the cutting member 30 form the protrusion 21 and the hole 22 of the transverse element 10. Play a role. In the example shown, the hole 22 is formed on the cutting member 30 side, and therefore the member 33 extending into the hole 32 in the cutting member 30 is hereinafter referred to as a hole forming member 33. Further, the recessed portion 42 of the blanking surface 41 of the support member 40 is hereinafter referred to as a protruding portion recess 42. A cutting blanking assembly 36 is constituted by the cutting member 30 and the hole forming member 33, and the cutting member 30 and the hole forming member 33 which are a part of the cutting blanking assembly 36 are provided so as to move relative to each other. It has been.

  During the blanking operation, the cutting member 30 and support member 40 on one side and the guide block 62 and mold 64 on the other side move relative to each other. This mutual movement pushes the cutting member 30 through the base material 50 and separates the blanking portion 51 from the remaining portion 52, thereby forming the transverse element 10. During the blanking operation, the blanking portion 51 is supported by the support member 40. Further, the blanking portion 51 is locally processed by the hole forming member 33, whereby the protrusion 21 and the hole 22 are formed in the blanking portion 51. Hereinafter, the different stages of the blanking operation will be further described.

  In the first stage, as shown in FIG. 4, the base material 50 is placed between the entire guide block 62 and cutting blanking assembly 36 on one side and the mold 64 and support member 40 on the other side. Is done.

  Starting from the first stage, the entire guide block 62 and cutting blanking assembly 36 on one side and the mold 64 and support member 40 on the other side move toward each other, thereby providing a blanking portion of the base material 50. 51 is clamped between the cutting blanking assembly 36 and the support member 40 to reach the second stage. From the second stage to the third stage, as shown in FIG. 5, the mutual position of the guide block 62 and the mold 64 is maintained, and the pressure to the blanking portion 51 increases. Further, the entire cutting blanking assembly 36 with the blanking portion 51 clamped therebetween and the support member 40 start operation, and the cutting member 30 cuts the base material 50. This operation is downward in the orientation of the various components of the blanking device shown in FIGS. The mutual movement of the cutting member 30 and the hole forming member 33 extending along the cutting member 30 is an operation in a direction toward the blanking portion 51. A pressure is applied to the blanking portion 51 at a position where the hole forming member 33 and the projecting depression 42 are present, whereby a cold forming process is performed, and a hole is formed on the cutting blanking assembly 36 side of the blanking portion 51. A portion 22 is formed, and a protrusion 21 is formed on the blanking portion 51 on the support member 40 side.

  In further operation of the entire cutting blanking member 36 and support member 40 with the blanking portion 51 clamped therebetween, the cutting member 30 further penetrates through the base material 50 as shown in FIG. Eventually, the blanking portion 51 is completely separated from the remaining portion 52. Further operation of the entire cutting blanking assembly 36 with the blanking portion 51 clamped therebetween and the support member 40 creates a rough shape of the transverse element 10. From the fourth stage to the fifth stage, as shown in FIG. 7, the cutting member 30 and the hole forming member 33 move relative to each other in the direction in which the hole forming member 33 is submerged in the cutting member 30. In this process, the contact between the hole forming member 33 and the transverse element 10 disappears due to the separation of the hole forming member 33 and the transverse element 10. Furthermore, the entire cutting blanking assembly 36 and the transverse element 10 move away from each other while the transverse element 10 remains supported by the support member 40. In this situation, the entire guide block 62 and cutting blanking assembly 36 on one side is separated from the entire mold 64 and support member 40 on the other side to remove the transverse element 10 and the next blanking operation. A space for placing a new base material 50 is reserved. To remove the transverse element 10, the support member until the transverse element 10 reaches the space between the entire guide block 62 and the cutting blanking assembly 36 on one side and the entire mold 64 and the support member 40 on the other side. 40 moves relative to the mold 64. As a result, the final stage shown in FIG. 8 is reached. At this stage, the transverse element 10 is removed from the blanking area and further processed to be ultimately suitable for use on the push belt 6.

  In general, in order to improve the quality of the push belt 6 by optimally functioning the transverse element 10 in the push belt 6, in the blanking process of the transverse element 10, the dimension and shape of the transverse element 10 are a predetermined size and shape. It is very important to process accurately so that According to the present invention, as described below, special measures are taken to prevent deviations in the size and shape of the hole 22. This is because the hole portion actually obtained by the blanking oil existing between the hole forming member 33 and the surface of the blanking portion 51 to which pressure is applied by the hole forming member 33 during the blanking process. This is based on the view that there is a deviation between 22 and the theoretically defined hole. If this oil cannot flow from this location, unintended additional marks will be formed in the blanking portion 51.

  In the first embodiment within the scope of the present invention, a discharge groove 37 is provided on the inner surface 35 of the hole 32 in the cutting member 30. These discharge grooves 37 are shown in the cutting member 30 shown in FIG. In FIG. 9, it should be noted that the discharge groove 37 is drawn greatly exaggerated. Actually, the function of the cutting member 30 to guide the hole forming member 33 during the blanking operation so that the accuracy when the cutting member 30 arranges the hole forming member 33 in the hole 32 is not lowered. In order not to decrease, the discharge groove 37 is provided smaller than that shown in FIG.

  In the example shown, two discharge grooves 37 extending in the longitudinal direction are provided, and the discharge grooves 37 are arranged at equal intervals along the peripheral surface of the hole 32 of the cutting member 30. This means that when there are two discharge grooves 37, the discharge grooves 37 are provided so as to face each other in the diametrical direction. It is advantageous to position the discharge groove 37 so that the discharge groove 37 is located where there is relatively much material on the cutting member 30 so that the cutting member 30 is not significantly weakened. It is also advantageous to design the discharge groove 37 so that no sharp corners or the like are formed in the material of the cutting member 30, thereby reducing undesired tension generated in the cutting member 30 to a minimum. In general, it is certainly possible to provide the discharge groove 37 in the cutting member 30 without significantly increasing the possibility of the cutting member 30 being damaged.

  In the scope of the present invention, the number of the discharge grooves 37 is not necessarily two, and for example, three or more discharge grooves 37 may be provided. Usually, in order to temporarily drain oil from the region between the hole forming member 33 and the surface of the blanking portion 51 to which pressure is applied by the hole forming member 33 during the blanking operation, the cutting member 30 and It is important to provide one or more spaces between the surfaces 34 and 35 of the hole forming member 33. For the purpose of providing a desired space, a recess having a shape different from the groove shape may be provided on the inner surface 35 of the hole 32 of the cutting member 30.

  Within the scope of the present invention, for example, a conventional cutting member 30, i.e. a cutting member 30 without a discharge groove 37 or another suitable recess, may be used. At this time, a recess is provided on the surface 34 of the hole forming member 33. Actually, the hole forming member 33 has a substantially circular cross section, and the surface 34 of the member 33 is bent. Thus, the desired recess is provided as a flat region 38 of the surface 34, for example. A hole forming member 33 provided with such a flat region 38 is shown in FIG. 10, and FIG. 11 shows one end portion of the member 33.

  In the example shown, the flat regions 38 extend long, and these regions extend in the longitudinal direction of the hole forming member 33. 10 and 11, the width dimension of the flat region 38 that extends long is intentionally greatly exaggerated. In practice, the flat area 38 is considerably smaller than this, for reasons indicated in the example described in the example in which the discharge groove 37 is provided in the inner surface 35 of the hole 32 of the cutting part 30. For the same reason as stated in the description of the deviation between the dimensions and the actual dimensions. The number of flat regions 38 may be two as shown in the example, but may be three or more, for example.

  It will be apparent to those skilled in the art that the scope of the present invention is not limited to the examples described above, and that changes and modifications can be made without departing from the scope of the present invention as set forth in the claims. .

  The present invention is summarized as follows. During the blanking operation in which the transverse element 10 used in the push belt 6 for the continuously variable transmission 1 is punched from the base material 50, a hole forming member 33 is formed to form the hole 22 on the surface of the transverse element 10 to be punched. Is used. The hole forming member 33 is accommodated in a hole 32 in another member used for punching. The other member is, for example, cut through the base material 50 through the base material 50 to cut the transverse element. It is the cutting member 30 which has the cutting edge which cuts out the rough type | mold. The surfaces 34 and 35 of the cutting member 30 and the hole forming member 33 except for at least one region in the recesses 37 and 38 provided in at least one of the surfaces 34 and 35 of the cutting member 30 and the hole forming member 33. Are closely joined. For example, the groove 37 may be provided in the inner surface 35 of the hole 32 of the cutting member 30, or the region 38 of the surface 34 of the hole forming member 33 may be formed flat. Thereby, during the blanking process, oil is removed from the region between the hole forming member 33 and the formed transverse element 10, and thereby the material of the transverse element 10 is affected by the oil in that region. It is possible to prevent unintended marks from being formed. This has the important advantage that the displacement of the size and shape of the hole 22 can be prevented.
