Description

Technical Field

[0001] The invention relates to the field of stamping dies, in particular to a stamping die for steel wheel spokes. Background Art

[0002] The wheel spoke is the part that connects the rim and the hub, and mainly plays a supporting and fixing role. According to its structure, wheels can be divided into two types: spoke plate type and spoke type. The spoke plate type spoke is usually composed of a pair of circular cover plates. The diameter of the cover plate is close to the diameter of the rim. There is a hole in the center of the cover plate that is larger than the wheel rotation axis. There is an opening near the edge. There is also a ring-shaped wheel plate on the edge of the cover plate. The curved surface of the wheel plate can fit closely with the curved surface of the rim, thereby enhancing the stability of the overall structure.

[0003] When producing spoke-plate type spokes, a circular plate is first cut, holes are punched on the circular plate to form holes required for spoke installation, and then the circular plate is stamped to form spokes with concave shapes.

[0004] When stamping the spokes, the disc workpiece is placed between the stamping lower die and the upper die. The upper and lower dies are used to stamp the rings under the action of the press. However, after the stamping of the disc workpiece is completed, the upper die rises and separates from the lower die. Not only must the stamped disc workpiece be taken out, but the disc workpiece to be stamped must also be placed in the lower die. This requires the upper die to be in an open state for a period of time, which makes it inconvenient for the upper die to perform continuous stamping work, thereby reducing its production efficiency.

Specific embodiments

[0076] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0077] Embodiment 1

[0078] The present invention provides as Figures 1-10A steel wheel spoke stamping die shown in the figure comprises a bearing platform 1, a lower die base 2, a bearing detection component 3, a press machine 4, an upper die base 5 and a driving component 6. The lower die base 2 is arranged on the bearing platform 1, and the bearing detection component 3 is installed on the bearing platform 1. The bearing detection component 3 is used to bear the lower die base 2 and detect the position of the lower die base 2. The press machine 4 is installed on the top of the bearing platform 1, and the upper die base 5 is transmission-installed at the output end of the press machine 4. The upper die base 5 cooperates with the lower die base 2 to stamp the spoke workpiece, and under the action of the bearing detection component 3, the accuracy of the mold closing of the upper die base 5 and the lower die base 2 can be guaranteed, that is, the wheel spoke workpiece is placed on the lower die base 2, and the press machine 4 drives the upper die base 5 and the lower die base 2 to close the wheel spoke. When the die base 2 is closed, the wheel spoke workpiece can be stamped. The driving component 6 is installed on the front side of the bearing platform 1. The driving component 6 is used to drive the lower die base 2 to revolve, that is, the press machine 4 drives the upper die base 5 to rise, and the driving component 6 drives multiple lower die bases 2 to revolve, so that the lower die base 2 with the stamped wheel spoke workpiece rotates and is separated from the upper die base 5, and the lower die base 2 with the unstamped wheel spoke workpiece rotates to the bottom of the upper die base 5, so that the upper die base 5 directly descends and cooperates with the lower die base 2 to stamp the wheel spoke workpiece, and the driving component 6 drives the lower die base 2 to separate from the load-bearing detection component 3, and also drives the lower die base 2 to rotate and withdraw from the die, thereby improving the efficiency of the stamping of the wheel spoke workpiece.

[0079] In particular, the driving assembly 6 includes a carrier frame 61, a mounting shell 62, a connecting assembly 63 and a flipping guide assembly 64. The carrier frame 61 is fixedly mounted on the front side of the carrier platform 1, the mounting shell 62 is rotatably mounted on the top of the carrier platform 1, the connecting assembly 63 is arranged on the mounting shell 62 in a ring array, and the lower die base 2 is rotatably mounted on the side of the mounting shell 62 through the connecting assembly 63. Under the action of the connecting assembly 63, the lower die base 2 can follow the mounting shell 62 for revolution, and can also make the lower die base 2 rotate relative to the connecting assembly 63. The flipping guide assembly 64 is arranged between the connecting assembly 63 and the mounting shell 62. The flipping guide assembly 64 is used to limit the self-rotation guide of the lower die base 2, that is, under the action of the flipping guide assembly 64, When the lower die base 2 follows the installation shell 62 to revolve and separate from the upper die base 5, the lower die base 2 can rotate once within a stroke, so that the lower die base 2 can be automatically demolded. The driving assembly 6 also includes a driving shaft 65, a reducer 66 and a servo motor 67. The outer wall of the driving shaft 65 is rotatably connected to the support frame 61. The installation shell 62 is fixedly installed on the top of the driving shaft 65. The reducer 66 and the servo motor 67 are both installed on the bottom of the support frame 61. The servo motor 67 is connected to the driving shaft 65 through the reducer 66. The servo motor 67 drives the driving shaft 65 to rotate through the reducer 66. The driving shaft 65 can drive the installation shell 62 to rotate, so that the installation shell 62 drives multiple lower die bases 2 to revolve through the connecting assembly 63.

[0080] Further, the connecting component 63 includes a connecting sleeve 631, a connecting shaft 632 and a locking component 633. The outer wall of the connecting sleeve 631 is slidably inserted and sleeved with the mounting housing 62. The connecting sleeve 631 forms a linkage with the flipping guiding component 64. The outer wall of the connecting shaft 632 is slidably sleeved with the connecting sleeve 631. One end of the connecting shaft 632 is fixedly connected to the lower die base 2. Under the action of the connecting shaft 632 and the connecting sleeve 631, the lower die base 2 can revolve following the mounting housing 62. When the connecting shaft 632 and the connecting sleeve 631 rotate relative to the mounting housing 62, the self-rotation of the lower die base 2 can be achieved. The locking component 633 is arranged on the mounting housing 62 and is used to lock the position of the connecting shaft 632 inside the connecting sleeve 631. Under the action of the locking component 633, the stability of the connecting shaft 632 installed inside the connecting sleeve 631 can be ensured. By releasing the locking of the connecting shaft 632 by the locking component 633, the lower die base 2 can drive the connecting shaft 632 to separate from the connecting sleeve 631, so as to directly disassemble and replace the multiple lower die bases 2 outside the mounting housing 62.

[0081] Specifically, the connecting component 63 further includes a fixed collar 634, a flange housing 635, a plain bearing 636, a clamping groove 637 and a clamping block 638. The fixed collar 634 is fixedly sleeved on the outside of the connecting sleeve 631. The flange housing 635 is fixedly installed on the outside of the mounting housing 62. The flange housing 635 is sleeved on the outside of the fixed collar 634. The flange housing 635 can limit the connecting sleeve 631 by limiting the fixed collar 634, so as to ensure the stability of the rotational connection between the connecting sleeve 631 and the mounting housing 62. The plain bearing 636 is sleeved on the outside of the connecting sleeve 631 and is located on the side of the fixed collar 634. The plain bearing 636 can reduce the friction force received by the fixed collar 634 when the connecting sleeve 631 rotates. The clamping groove 637 is opened at the end of the connecting sleeve 631. The clamping block 638 is fixedly connected to the outside of the connecting shaft 632. The outer wall of the clamping block 638 is slidably clamped with the inner cavity of the clamping groove 637, and the clamping block 638 is clamped in one end of the connecting sleeve 631 located outside the mounting housing 62 through the clamping groove 637. Under the action of the clamping block 638, the connecting shaft 632 and the connecting sleeve 631 can maintain a synchronous rotation state.

[0082] Further, the locking component 633 includes a clamping member 6331, an annular groove 6332, a connecting member 6333, a connecting collar 6336, a handle 6337, a fixing rod 6334, and a limiting spring 6335. The annular groove 6332 is formed at one end of the outer wall of the connecting shaft 632. The clamping member 6331 is slidably clamped inside the annular groove 6332. The clamping member 6331 is in contact with the end of the connecting sleeve 631. Under the action of the clamping block 638, the connecting shaft 632 cannot slide relative to the connecting sleeve 631 towards the inside of the mounting housing 62. And since one side of the clamping member 6331 is in contact with the end of the connecting sleeve 631, the connecting shaft 632 cannot move relative to the connecting sleeve 631 towards the outside of the mounting housing 62 under the limitation of the clamping member 6331, thus ensuring the stability of the connection between the connecting shaft 632 and the connecting sleeve 631. And the clamping member 6331 is clamped in the annular groove 6332 outside the connecting shaft 632, so that the connecting sleeve 631 and the connecting shaft 632 can also rotate relative to the clamping member 6331. The connecting member 6333 is fixedly connected to one side of the clamping member 6331, and a connecting ring is fixedly connected between multiple connecting members 6333, thus ensuring the stability of multiple connecting members 6333 and multiple clamping members 6331. The connecting collar 6336 is arranged on the top of the mounting housing 62. The handle 6337 is fixedly connected to the top of the connecting collar 6336. The fixing rod 6334 is fixedly connected between the connecting collar 6336 and the connecting member 6333. By driving the connecting collar 6336 to rise with the handle 6337, the connecting collar 6336 can drive multiple connecting members 6333 and clamping members 6331 to rise through multiple fixing rods 6334, so that the clamping member 6331 is separated from the annular groove 6332 outside the connecting shaft 632, thus releasing the locking state of the connecting shaft 632, and the multiple lower die bases 2 can be directly disassembled and replaced. When the lower die base 2 is replaced, the upper die base 5 needs to be replaced uniformly. The limiting spring 6335 is slidably sleeved outside the fixing rod 6334. The limiting spring 6335 is located between the connecting member 6333 and the mounting housing 62. The limiting spring 6335 can give a downward elastic force to the clamping member 6331 through the connecting member 6333, thus ensuring the stability of the clamping of the clamping member 6331 with the annular groove 6332 outside the connecting shaft 632.

[0083] In particular, the flipping guiding assembly 64 includes a first circular ring 641, a driving gear 642, and a rack 643. The first circular ring 641 is fixedly connected to the top of the carrier 61. The first circular ring 641 is sleeved inside the mounting housing 62. The driving gear 642 is fixedly installed on the outside of the connecting sleeve 631. The rack 643 is fixedly connected to the top of the first circular ring 641. The rack 643 is meshed with the driving gear 642 for driving the lower die holder 2 to flip. After the mounting housing 62 drives the lower die holder 2 to be misaligned and separated from the upper die holder 5 through the connecting sleeve 631 and the connecting shaft 632, the driving gear 642 outside the connecting sleeve 631 will be meshed with the rack 643. Thus, when the mounting housing 62 continues to drive the connecting sleeve 631 to rotate, the driving gear 642 rolls on the rack 643, so that the connecting sleeve 631 and the connecting shaft 632 rotate relative to the mounting housing 62, and further realize the self-rotation of the lower die holder 2. When the lower die holder 2 rotates 180 degrees, the lower die holder 2 faces downward, and the wheel spoke workpieces inside the lower die holder 2 fall off. When the driving gear 642 is separated from the rack 643, the connecting sleeve 631 and the connecting shaft 632 rotate one week, that is, the lower die holder 2 rotates one week, and then the lower die holder 2 can be replenished with materials. The flipping guiding assembly 64 further includes a fixing member 644, a roller 645, a second circular ring 646, a notch groove 647, and a shaft seal sleeve 648. The fixing member 644 is fixedly connected to the end of the outer wall of the connecting sleeve 631. The roller 645 is rotatably installed at the corner of the fixing member 644. The second circular ring 646 is fixedly connected to the top of the carrier 61. The roller 645 is in contact with the top of the second circular ring 646 for guiding the revolution of the lower die holder 2. That is, when the two rollers 645 at the bottom of the fixing member 644 are in contact with the top of the second circular ring 646, the two rollers 645 limit the connecting sleeve 631 through the fixing member 644, so that the connecting sleeve 631, the connecting shaft 632, and the lower die holder 2 are in a relatively static state with respect to the mounting housing 62. At this time, the driving gear 642 and the rack 643 are in a separated state. The notch groove 647 is opened at the top of the second circular ring 646. The notch groove 647 is used for the fixing member 644 and the roller 645 to flip and rotate. When the roller 645 is located at the notch groove 647, the driving gear 642 and the rack 643 are in a meshed state, and the notch groove 647 can make the fixing member 644 and the roller 645 rotate following the connecting sleeve 631, avoiding the roller 645 restricting the driving gear 642 from walking on the rack 643 when the driving gear 642 is meshed with the rack 643. The shaft seal sleeve 648 is fixedly connected to the top of the carrier 61. A lubricating oil cavity is formed between the shaft seal sleeve 648 and the first circular ring 641. The lubricating oil cavity is used for storing lubricating oil liquid, and the height of the lubricating oil liquid is lower than the top of the second circular ring 646 and higher than the bottom of the inner wall of the notch groove 647. Thus, when the fixing member 644 and the roller 645 roll in the notch groove 647, the roller 645 can also be in contact with the lubricating oil liquid to automatically lubricate the roller 645.

[0084] Based on Embodiment 1, as Figure 11 shown, the load detection component 3 includes a carrier plate 31, a pressure sensor 32, a first arc block 34 and a second arc block 35. The carrier plate 31 is fixedly connected to the top of the carrier table 1. The top of the carrier plate 31 is in contact with the lower die base 2. An inclined slope is provided on the side of the carrier plate 31, so as to facilitate the sliding of the lower die base 2 to the top of the carrier plate 31. Under the support of the carrier plate 31, the lower die base 2 can be in a stable state to perform stamping work with the upper die base 5. The pressure sensor 32 is installed inside the carrier plate 31. The first arc block 34 is arranged on the top of the pressure sensor 32. The second arc block 35 is fixedly connected to the bottom of the lower die base 2. The second arc block 35 is used to squeeze the first arc block 34 and the pressure sensor 32. When the lower die base 2 moves to the top of the carrier plate 31 and corresponds to the upper die base 5, the second arc block 35 at the bottom of the lower die base 2 can slide to the top of the first arc block 34, so as to drive the first arc block 34 to descend and squeeze the pressure sensor 32. By transmitting an electrical signal from the pressure sensor 32, it can be known that the lower die base 2 has moved into place, and the movement of the lower die base 2 can be stopped, so that the lower die base 2 and the upper die base 5 cooperate to perform stamping processing on the wheel spoke workpiece. A guiding sleeve is fixedly connected to the side of the lower die base 2, and a guiding column is fixedly connected to the side of the upper die base 5. Thus, when the upper die base 5 and the lower die base 2 are closed, the guiding column and the guiding sleeve can further improve the closing accuracy of the upper die base 5 and the lower die base 2.

[0085] Furthermore, the load detection component 3 further includes a slot 33, a mounting groove, a sliding groove 36, a sliding block 37, a guiding rod 38 and a return spring 39. The slot 33 is opened on the top of the carrier plate 31. The slot 33 is used for the sliding of the second arc block 35, so as to avoid the situation that the second arc block 35 is stuck with the carrier plate 31. The mounting groove is opened at the bottom of the carrier plate 31. The pressure sensor 32 is installed at the bottom of the inner cavity of the mounting groove. The sliding groove 36 is opened on the side of the inner wall of the mounting groove. The sliding block 37 is fixedly connected to the bottom of the side of the first arc block 34. The outer wall of the sliding block 37 is slidably sleeved in the inner cavity of the sliding groove 36. The guiding rod 38 is fixedly connected to the inside of the sliding groove 36. The outer wall of the guiding rod 38 is slidably inserted through the sliding block 37. The return spring 39 is slidably sleeved on the outside of the guiding rod 38. The return spring 39 is located at the bottom of the sliding block 37. When the second arc block 35 is separated from the first arc block 34, the return spring 39 can give an upward elastic force to the first arc block 34 through the sliding block 37, so as to reset the first arc block 34 and the pressure sensor 32 no longer receives pressure.

[0086] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
