[0040] The utility model discloses a nail-piercing die for a deep groove ball retainer, which improves the production efficiency of the deep groove ball retainer.
[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0042] like Figure 1-Figure 3 As shown, Figure 1 A schematic diagram of the station arrangement structure of the deep groove ball retainer nailing mold provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the front side layout structure of the medium and deep groove ball retainer nailing die; Figure 3 for Figure 1 Schematic diagram of the rear side layout structure of the medium and deep groove ball retainer nail insertion mold.
[0043] The present embodiment provides a deep groove ball retainer nailing mold, which is used for the synchronous preparation of an empty batch retainer 1 and a nailing retainer 2, including a front station 11 for forming and punching an annular substrate to prepare an empty batch retainer, and sending two adjacent empty batch retainers 1 to a nail pressing station 105 for preparing a nailing retainer 2, and to an empty batch output station 104 of an empty batch retainer output device; and also includes a retainer transfer device for transferring materials between the front station 11, the nail pressing station 105 and the empty batch output station 104. The front station 11 performs stamping and punching on the annular substrate of the prepared retainer to form an empty batch retainer 1. In order to realize the installation of rivets on the empty batch retainer 1, the rivet pressing station 105 installs the rivet into the rivet hole of the empty batch retainer 1. The nail pressing station 105 and the empty batch output station 104 are simultaneously set after the front station 11. Two adjacent empty batch retainers 1 can be sent to the two stations at the same time and separately, and the nailed retainer 2 after nailing and the empty batch retainer 1 without nailing are obtained at the same time. At the same time, a pair of nailed retainers 2 and empty batch retainers 1 for embracing and fitting the rolling elements of the deep groove ball bearing are obtained. During the preparation process of the empty batch retainer 1, the switching between different stations is realized by the retainer transfer device. When the annular substrate is transferred between different stations, the retainer transfer device continues to send it to the subsequent station after completing the processing of one station, so as to realize the continuous processing of the deep groove ball retainer and improve the processing efficiency.
[0044] The deep groove ball retainer is used to hold the rolling element in the deep groove ball bearing and seal it between the inner and outer rings of the bearing. Before the retainer is assembled, the blank retainer 1 and the nail retainer 2 are two independent components. The blank retainer 1 and the nail retainer 2 have the same structure. After the rivets are pre-installed in the rivet holes of the blank retainer 1, the nail retainer 2 is obtained. During the preparation process, the blank retainer 1 and the nail retainer 2 are processed by the front station 11 to obtain a pocketing structure for the pocketed rolling element.
[0045] The front station 11 performs preliminary processing on the annular substrate, including stamping the annular substrate and punching rivet holes to prepare the empty batch retainer 1. Since the deep groove ball retainer is a retainer structure composed of an empty batch retainer 1 and a nail-piercing retainer 2 assembled in pairs, a set of molds is used to prepare the retainer, and it is necessary to overcome how to simultaneously output the nail-piercing retainer 2 with nails and the empty batch retainer 1 without nails, and complete the independent collection of the two retainers at the same time.
[0046] Based on the structural characteristics of the deep groove ball retainer, and in order to achieve the simultaneous preparation and output of two different structures of retainers, an empty batch output station 104 and a nail pressing station 105 are set up after the front station 11. When the retainer is transferred at different stations, different processing molds are required for sequential processing, and the retainer transfer device is used for sequential transfer. By setting up an independent nail pressing station 105 and an empty batch output station 104, the empty batch retainer 1 and the nailing retainer 2 can be transported at the same time on the two stations, and then the pairs of retainers can be transported synchronously.
[0047] In a specific embodiment of the present case, the feed end of the empty batch output station 104 is arranged between the front station 11 and the nail pressing station 105. The nail pressing station 105 has a nail pressing lower mold 51 for placing the empty batch retaining frame to be nailed, and a nail pressing upper mold 52 that cooperates with the nail pressing lower mold 51 to press and install the nail retaining frame 2; it also includes a position switching device for switching the position of the nail pressing lower mold 52 between the feed end and the nail pressing station 104.
[0048] Specifically, the position switching device includes a guide rail 61 disposed between the nail pressing station 105 and the feed end, and a nail pressing lower die slide plate 53 disposed at the lower end of the nail pressing lower die 51 and slidably matched with the guide rail 61;
[0049] The nail pressing lower die 51 slides to the feeding end to receive the empty batch holder 1 transferred by the front station 11, and returns to the nail pressing station 105 after receiving the empty batch holder 1.
[0050] The annular substrate needs to be gradually transported between different workstations and different molds on the workstations according to the processing rhythm. The transport rhythm of the empty batch output station 104 and the nail pressing station 105 is matched with the rhythm of the front station 11, so that one processing action can be completed during each mold opening and closing process.
[0051] In this embodiment, the front station 11, the empty batch output station 104 and the nail pressing station 105 are arranged in sequence. After the front station 11 completes the preparation of the empty batch holder 1, the empty batch holder 1 is sent to the empty batch output station 104 in the next beat; in the next two beats, the empty batch holder 1 is sent to the nail pressing station 105; and the front empty batch holder adjacent to the empty batch holder 1 continues to be sent to the empty batch output station 104.
[0052] The empty batch holder of the next beat is kept at this position, and the adjacent empty batch holder that is re-sent in the next two beats is output, and the nail pressing station 105 completes nailing. At this time, the two adjacent empty batch holders 1 and the nailing holder 2 can be output synchronously. That is, the empty batch output station 104 does not output the empty batch holder in one beat, but the nail pressing lower mold 51 slides to this position and brings the empty batch holder back to the nail pressing station 105 for nailing, so that the continuous output of two adjacent empty batch holders can be achieved.
[0053] Based on this working principle, the nailing action is completed when the nail pressing upper mold 52 and the nail pressing lower mold 51 of the nail pressing station 105 are closed. A position switching device of a slide plate and a slide rail structure is set at the bottom of the nail pressing lower mold 51. The guide slide rail 61 is arranged between the empty batch output station 104 and the nail pressing station 105. The nail pressing lower mold 51 slides to the empty batch output station 104, opposite to its feeding end position. When the holder transfer device transfers the empty batch holder 1, it enters the empty batch output station 104 and can be placed on the nail pressing lower mold 51. After receiving the empty batch holder 1, the nail pressing lower mold 51 slides back to the nail pressing station 105.
[0054] At this time, since the nail pressing lower die 51 has returned to the nail pressing station 105, when the empty batch retainer 1 continues to be fed into the feed end of the empty batch output station 104, it can directly fall onto the empty batch output station 104, and the empty batch retainer 1 can be directly output.
[0055] Since the lower die 51 needs to switch between different workstations and cooperate with the upper die 52 to insert rivets, its stability in the clamping direction needs to be ensured. A lower die slide plate 53 is provided at the lower end of the lower die 51, and the lower die slide plate 53 is fixed on a linear bearing 62. A guide rail 61 is provided to cooperate with the linear bearing 62 to satisfy the sliding and supporting functions.
[0056] In a specific embodiment of the present case, the empty batch output station 104 is also provided with a nail feeding device 41 for placing rivets into the empty batch retaining frame 1 on the nail pressing lower die 51; the nail feeding device 41 performs the nail feeding action when the nail pressing lower die 51 slides to the feeding end.
[0057] The empty batch retainer 1 completes the nailing action, which can be decomposed into placing the rivets into each rivet hole first, and then pressing the rivets into the rivet holes by punching after they are placed in place. That is, the nail pressing station 105 is decomposed into two processing actions: placing rivets-pressing rivets.
[0058] In this embodiment, preferably, an empty batch output station 104 is used. When the lower die 51 of the press nail receives the empty batch holder 1, the production cycle of the mold will be closed once at the same time. A nail feeding device 51 is set at the empty batch output station 104. During the closing process, the nail feeding device 41 completes the work of placing rivets on the lower die 51 of the press nail. After the cycle is completed, the lower die 51 of the press nail slides back to the closing position with the upper die 52 of the press nail. When the next cycle of closing the mold, the upper die 52 of the press nail closes with the lower die 51 of the press nail, and the rivet is pressed into the empty batch holder. A press nail needle 53 is set on the upper die 52 of the press nail, and the rivet is pressed into the empty batch holder. A press nail base 54 is also set on the upper tooling plate 12, and the upper die 52 of the press nail is fixed on the upper tooling plate 12 through the press nail base 54, which is used to adjust the pressing height of the upper die 52 of the press nail.
[0059] Furthermore, it also includes an upper tooling plate 12 and a lower tooling plate 13 for stamping cooperation, and the front station 11, the empty batch output station 104 and the nail pressing station 105 are sequentially arranged between the upper tooling plate 12 and the lower tooling plate 13.
[0060] The lower tooling plate 12 is used to install the upper mold, and the lower tooling plate 13 is used to install the lower mold. At the empty batch output station 104, the nail feeding device 41 is set on the upper tooling plate 12, and the nail feeding station is set at the same time when the mold is closed, that is, the nail pressing lower mold 51 slides to the feeding end of the empty batch output station 104. When the mold is closed, the nail feeding device 41 cooperates with the nail pressing lower mold 51 to place the rivet into each rivet hole of the empty batch retainer on the nail pressing lower mold 51.
[0061] The nail feeding device 41 includes a disc-shaped nail feeding die 42. The nail feeding side of the nail feeding die 42 is provided with nail feeding claws 43 corresponding to each rivet hole position on the empty batch holder. The nail feeding claws 43 are connected to the nail feeding channel to ensure the continuous feeding of the rivets. The nail feeding cylinder 44 is arranged on the back side of the nail feeding die 42. The nail feeding cylinder 44 is fixed on the upper tooling plate 12. With the clamping of the upper tooling plate 12 and the lower tooling plate 13, when entering the nail feeding rhythm, the nail feeding device 41 feeds the rivet into each rivet hole.
[0062] A nail-piercing retainer conveyor belt 106 for outputting the nail-piercing retainer 2 is provided at the end of the lower tooling plate 13, and the nail-piercing retainer conveyor belt 106 is arranged along a first direction along the length direction of the lower tooling plate 13;
[0063] The empty batch output station 104 is provided with an empty batch holder conveyor belt 45 , and the empty batch holder conveyor belt 45 is arranged along a second direction of the width direction of the lower tooling plate 13 .
[0064] In the present application, the nail pressing station 105 is the last station for preparing the nail holding frame 2, and the empty batch output station 104 is located between the nail pressing station 105 and the front station 11. In order to facilitate the material transfer between the stations, the lower tooling plate 13 adopts a station arrangement structure in the length direction, then, the length direction of the lower tooling plate 13, that is, the material transmission direction is set as the first direction, and the width direction of the lower tooling plate 13 is set as the second direction.
[0065] In this embodiment, a first receiving device for collecting the nail-piercing retainers is provided at the conveying end of the nail-piercing retainer conveyor belt 106; a second receiving device for collecting the empty batch retainers is provided at the conveying end of the empty batch retainer conveyor belt 45.
[0066] In order to avoid interference in material transmission between the two stations, after the nail-piercing retainer 2 is prepared at the nail-pressing station 105, it is continuously fed to the nail-piercing retainer conveyor belt 106 at the end, and the nail-piercing retainer 2 is collected by the first receiving device at the end. When the empty batch retainer 1 is in the nail-pressing cycle at the nail-pressing station 105, it is fed to the feed end of the empty batch retainer conveyor belt 45, directly falls on the empty batch retainer conveyor belt 45, and is output with the conveyor belt transmission, and the material is collected by the second receiving device.
[0067] In a specific embodiment of the present case, the guide rail 61 is fixed on the lower tooling plate 13, and the lower tooling plate 13 is also provided with a linear module 63 arranged in parallel with the guide rail 61, and a driving device 65 for driving the linear module 63 to move;
[0068] The linear slide 64 of the linear module 63 is fixedly connected to the lower die slide 53 of the press nail;
[0069] The empty batch holder conveyor belt 45 is arranged below the guide rail 61 .
[0070] The lower tooling plate 13 is provided with a layout channel for arranging the empty batch holder conveyor belt 45, and the guide rail 61 is arranged above the layout channel, so that the lower die 51 of the press nail is at the same die height when switching between two stations. The guide rails 61 include two parallel arranged guide rails, and an opening is formed between the two guide rails 61 for the empty batch holder 1 to fall. When the empty batch holder 1 is transferred to the top of the empty batch holder conveyor belt 45, it automatically falls, falls onto the conveyor belt through the opening between the two guide rails 51, and is output with the conveyor belt. The surface of the empty batch holder conveyor belt 45 has a certain elastic tension, which prevents the empty batch holder from popping out when it falls automatically.
[0071] In order to ensure the stability of the reciprocating sliding of the guide slide 61 and the nail pressing lower mold slide plate 53, a linear module 63 is arranged on the lower tooling plate 13. The linear module 63 is arranged in parallel with the guide slide 61, and the linear slide 64 of the linear module 63 is fixedly connected to the nail pressing lower mold slide plate 63. A connecting plate 66 is provided between the two. The linear module 63 is driven by a driving device 65, specifically a servo motor, to realize the sliding of the linear slide 64. During the sliding process, the nail pressing lower mold 51 is switched between the nail pressing station 105 and the empty batch output station 104 according to the production rhythm.
[0072] In a specific embodiment of the present case, the front station 11 includes a forming die 101 arranged in sequence to perform circular bending on the annular substrate;
[0073] A shaping mold 102 for shaping the bent annular substrate into a spherical ball pocket; and
[0074] Punching rivet holes in the shaped annular substrate to prepare a punching die 103 for a blank batch retainer;
[0075] The empty batch output station 104 is arranged between the punching die 103 and the nail pressing station 105 .
[0076] The front station 11 is used to form the basic structure of the retainer on the annular substrate and punch holes to form rivet holes. The annular substrate is first formed once by a forming mold 101, which includes an upper forming mold 14 and a lower forming mold 15. The upper forming mold 14 is provided with an upper forming mold tooth, and the lower forming mold 15 is provided with a lower forming mold tooth. The two are extruded and matched to preliminarily process the annular substrate into a bending structure corresponding to different ball pocket positions.
[0077] The shaping mold 102 needs to form the bending structure into a corresponding rolling body, such as a spherical ball pocket of a spherical rolling body, or a circular arc surface ball pocket of a basic cylindrical shape. The shaping mold 102 includes a shaping upper mold 21 and a shaping lower mold 22. The shaping lower mold 22 has a shaping core 23, and a shaping ball 24 is placed on the shaping core 23. The two molds are combined to secondary mold the bending structure into a spherical or circular arc surface structure by the shaping ball 24.
[0078] The punching die 103 includes a punching upper die 31 and a punching lower die 32. The punching upper die 31 is provided with a punching needle 33, and the punching lower die 32 is provided with a punching hole. The two are matched with each other to punch a rivet hole on the ball pocket connection part of the cage after secondary molding, and the preparation of the blank batch cage 1 is completed. It also has a material collection channel connected to the material collection box 34, and the material punched out after punching the rivet hole is sent to the material collection box 34 through the material channel.
[0079] In order to ensure the structural stability of the forming mold 101, the shaping mold 102 and the punching mold 103 when installed on the upper tooling plate 12 and the lower tooling plate 13, each mold is provided with an upper mold plate 16 and an upper mold base 17, as well as a lower mold plate 18 and a lower mold base 19. The mold plate is used to connect with the tooling plate, and the mold base is used to connect with the mold, thereby improving the overall installation structural stability of the mold.
[0080] The empty batch output station 104 is arranged between the punching die 103 and the nail pressing station 105. After the punching is completed, the preparation of the empty batch retainer 1 is completed. The retainer transfer device first sends it to the empty batch output station 104 according to the production rhythm. When the nail pressing lower die 51 is located at the empty batch output station 104, the empty batch retainer 1 falls on the nail pressing lower die 51. At the same time, the nail feeding device 41 drops the rivet with the mold closing action, and the nail feeding die 42 abuts and cooperates with the nail pressing lower die 51, and the rivet thereon is automatically fed into the nail pressing lower die 51 for pre-installation; entering the next beat, the nail pressing lower die 51 slides back to the nail pressing station 105, and the nail pressing mold closes the mold to press the preset rivet into the rivet hole.
[0081] At the empty batch output station 104, on the one hand, since there is no lower nail pressing die 51 to receive the empty batch holder 1, the empty batch holder 1 directly falls onto the empty batch holder conveyor belt 45 for output. On the other hand, the nail feeding device 41 moves down with the mold closing action, and its lower end is empty. The nail feeding die 42 will not be blocked by the lower nail pressing die 51, and the nail feeding device 41 runs empty and does not deliver rivets. That is, by switching the lower nail pressing die 51 between the two stations, the two stations respectively perform empty running actions according to the mold closing rhythm, and the synchronous output of the empty batch holder 1 and the nail insertion holder 2 is realized.
[0082] In a specific embodiment of the present case, it also includes a frame for fixing the upper tooling plate 12 and the lower tooling plate 13 for stamping and fitting, and the frame includes a lower die base supporting the lower tooling plate, and an upper die base for installing the upper tooling plate;
[0083] The frame is also equipped with a continuous nail feeding device for conveying rivets in cooperation with the nail feeding device on the empty batch output station. The frame provides fixed support for the equipment, and realizes the fixed support of the lower tooling plate by the lower die base, and the upper tooling plate is fixedly connected to the lower die base, and realizes the upper and lower sliding support of the upper tooling plate on the frame.
[0084] The device is arranged on the upper tooling plate, and a continuous nail feeding device is set on the frame, including a nail feeding direction adjustment device for adjusting the nail feeding direction of the rivets, a conveying track for continuously conveying the rivets, a nailing barrel for carrying the rivets and other components.

[0086] In a specific embodiment of the present case, the retainer transfer device 7 includes a first transfer arm 71 and a second transfer arm 72 which are respectively arranged on both sides of the front station 11, the nail pressing station 105 and the empty batch output station 104.
[0087] A forming die 101, a shaping die 102 and a punching die 103 are arranged on the front station 11, an empty batch output station 104 is provided with an empty batch retainer conveyor belt 45 and a nail feeding device 41, a nail pressing station 105 is provided with a nail pressing die, and its rear end corresponds to a nail piercing retainer conveyor belt 106, and the six stations are sequentially arranged on the lower tooling plate 13. The retainer transfer device 7 needs to transfer the retainer on the front mold to the rear mold at the same time during each mold closing process. The retainer transfer device 7 is provided with a first transfer arm 71 and a second transfer arm 72, which are distributed on both sides of the lower tooling plate 13. When the mold is opened, they are extended at the same time to transfer the materials on each station.
[0088] Specifically, the first transfer arm 71 and the second transfer arm 72 extend relatively with clamping claws 73 corresponding to different stations for clamping and releasing the empty batch holder 1 or the nail holder 2. In order to facilitate the same travel distance of the clamping claws between different stations, the same spacing is set between different stations. Then, the first transfer arm 71 and the second transfer arm 72 reciprocate one station along the length direction to achieve a material transfer. Multiple clamping claws 73 are set at different stations, and each clamping claw 73 is provided with a clamping structure corresponding to its clamping station to clamp the products in different stations. For the empty batch holder and the nail holder, since the structures of the two have been formed, the clamping claws 73 can be set to cooperate with the ball pocket for clamping. Then, when switching between different stations, the holder is kept in the same position to ensure the consistency of the placement and pressing position of the rivet.
[0089] The first transfer arm 71 and the second transfer arm 72 are respectively provided with a first sliding frame 74 and a second sliding frame 75 at both ends in the length direction. The first sliding frame 74 and the second sliding frame 75 both have a transverse guiding device for guiding the first transfer arm 71 and the second transfer arm 72 to move relatively close to and away from each other, and a longitudinal guiding device for guiding the first transfer arm 71 and the second transfer arm 72 along the extension direction of the two.
[0090] In combination with the opening and closing action of the mold and the need for sequential transfer of materials in the direction of the workstation layout, the first transfer arm 71 and the second transfer arm 72 need to simultaneously perform reciprocating position switching actions, as well as clamping and releasing actions of the retaining frame that clamps the material along the width direction of the mold. A first sliding frame 74 and a second sliding frame 75 are set to synchronously perform reciprocating sliding in the width and length directions of the two parallel first transfer arms 71 and the second transfer arms 72.
[0091] The first sliding frame 74 and the second sliding frame 75 have the same structure. Taking the first sliding frame 74 as an example, a transverse guide device 741 and a longitudinal guide device 743 are provided. The transverse guide device 741 is two guide rails arranged transversely and can be fixed to the frame. The longitudinal guide device 743 is two guide rails fixed to the first transfer arm 71 and the second transfer arm 72 respectively. A guide rail connecting plate 742 is provided between the transverse guide device 741 and the longitudinal guide device 743. Through the driving device, the first transfer arm 71 and the second transfer arm 72 can synchronously perform transverse and longitudinal opening and closing actions to meet the station switching function of the retaining frame.
