Multiple roller sets are evenly arranged on the material supporting core.

[0004] However, the above-mentioned device still has some problems. In order to ensure the smooth progress of the stamping process, lubricant is used to assist the stamping work. However, the actual amount of lubricant cannot be accurately controlled, which will form a thick oil film on the surface of the mold and the workpiece when the amount of lubricant is too much or the viscosity of the lubricant is too large, adsorbing some impurities, thereby increasing the adhesion between the workpiece and the mold, causing the workpiece to adhere to the mold, and thus being not conducive to the demolding of the bell housing ball cage.

[0046] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced without the specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to obscure the present application. The present application is not limited to the embodiments described herein which are presented for the purpose of illustration and description only.

[0047] It is also noted that, as used herein, "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the present application. The appearances of the phrase "in one embodiment" or "an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are the cited items necessarily mutually exclusive.

[0048] The present application discloses a bell-shaped shell cold-rolled spline thread forming device, which comprises Figures 1-9 , and includes:

[0049] A workbench 1 and a machining unit 2 located on the workbench 1; the machining unit 2 comprises a punch press 21 connected with the workbench 1, a cleaning unit 4, an upper die seat 22 arranged on the punch press 21, at least two guide struts 23 symmetrically arranged on the upper die seat 22, and a lower die seat 24 arranged on the punch press 21; the lower die seat 24 is provided with a placing hole for placing a bell-shaped shell cage, a limiting assembly 25 embedded in the inner wall of the placing hole, and a blowing device 27 arranged in the lower die seat 24; the lower die seat 24 is provided with a groove matched with the guide struts 23, the bottom of the placing hole is provided with an air outlet 26 connected with the air outlet end of the blowing device 27, and the air outlet 26 is located in the area where the opening end of the bell-shaped shell cage contacts with the bottom of the placing hole, for blowing air into the opening end of the bell-shaped shell cage; a negative pressure adsorption device is further arranged in the device, for adsorbing iron filings in the punching process; when the adhesion of lubricating oil is low, the adjustable blowing device 27 is arranged to blow air through the two air outlets 26, and the horizontal position of the bell-shaped shell cage can be ensured while blowing air, so that the collision between the bell-shaped shell cage and the bottom of the lower die seat 24 caused by the excessive rising height of the bell-shaped shell cage when falling is avoided, and the damage of the lower die seat 24 is avoided; by changing the number of air outlets 26 of the blowing device 27, the air volume is changed, and the adhesion between the lower die seat 24 and the bell-shaped shell cage is selected, and the limiting assembly 25 is matched for work when one air outlet 26 is selected.

[0050] In further embodiments, at least one existing structure of a lead screw linear motion structure can be arranged on the inner wall of the placing hole, and then another limiting assembly 25 is arranged on the lead screw linear motion structure. During the clock shell ball cage stamping process, the side of the limiting wheel 254 in the limiting assembly 25 abuts against the surface of the clock shell ball cage, so as to apply a certain pressure to the clock shell ball cage in the radial direction and limit the clock shell ball cage. When one gas outlet 26 is used, the position of the limiting assembly 25 is adjusted through the lead screw linear motion structure, so that the bottom of the limiting wheel 254 abuts against the shoulder position of the clock shell ball cage, thereby limiting the position of the clock shell ball cage in the axial direction. When one gas outlet 26 is used, the excessive gas pressure can be avoided, so that the clock shell ball cage does not collide with the bottom of the lower die seat 24 when falling, thereby avoiding damage to the clock shell ball cage or the lower die seat 24. A buffer pad can be arranged at the bottom of the limiting wheel 254 to avoid collision between the clock shell ball cage and the limiting wheel 254 during the lifting process of the clock shell ball cage, thereby avoiding damage to the shoulder of the clock shell ball cage.

[0051] The blowing device 27 comprises a valve seat 271 arranged in the lower die seat 24, a driving part arranged in the valve seat 271, an air inlet pipe 2712 and two air outlet pipes 2713 arranged on the valve seat 271, two cavities respectively arranged in the valve seat 271, and a connecting channel respectively connecting the two cavities. One cavity is used to connect the air inlet pipe 2712 and one air outlet pipe 2713, and the other cavity is connected with the other air outlet pipe 2713. The air outlet pipes 2713 are respectively connected with the gas outlets 26. The driving part comprises a rotating wheel 273 movably connected with the valve seat 271, a driving motor 272 connected with the rotating wheel 273, a first driving rod 274 and a second driving rod 277 arranged in the length direction of the valve seat 271, a limiting block 275 arranged on the first driving rod 274, a first spring 276 used to connect the limiting block 275 and one air outlet pipe 2713, a driving block 278 arranged at the other end of the second driving rod 277, a second spring 279 connected with the driving block 278, a driven block 2710 connected with the second spring 279, and a limiting ball 2711 connected with the driven block 2710. The rotating wheel 273 is a cam structure, and the end away from the cam center abuts against the second driving rod 277. The rotating wheel 273 is further provided with a driving rod, which can abut against the first driving rod 274.

[0052] When it is necessary to make the bell-shaped shell cage separate from the lower die seat 24, because the two cavities are communicated through the connecting channel, the gas can be discharged from the gas outlet pipe 2713 by injecting gas into the gas inlet pipe 2712, and because the outlet end of the gas outlet pipe 2713 is communicated with the gas outlet 26, and the gas outlet 26 is located in the open end, the bell-shaped shell cage is separated from the lower die seat 24 by exhausting gas into the open end of the bell-shaped shell cage. When the attached impurities of the lubricating oil are too much, and at the same time, the extrusion of the bell-shaped shell cage during stamping causes the adhesion between the lower die seat 24 and the bell-shaped shell cage to be larger, at this time, the above method is difficult to make the bell-shaped shell cage separate from the lower die seat 24; at this time, the driving motor 272 rotates, the rotating driving motor 272 can drive the rotating wheel 273 to rotate, so that the pushing rod on the rotating wheel 273 and the farthest contact point from the cam center respectively abut against the first driving rod 274 and the second driving rod 277, which can drive the first driving rod 274 and the second driving rod 277 to move, so as to adjust the position of the limiting block 275 and the driving block 278 in the respective cavities, so that the limiting block 275 and the driving block 278 are away from the rotating wheel 273, the moving driving block 278 drives the driven block 2710 to move through the second spring 279, so that the limiting ball 2711 can block the gas inlet of one of the gas outlet pipes 2713, so that the blowing device 27 only has one gas outlet 26, at this time, the demolding work of the bell-shaped shell cage can be completed, and the situation that the bell-shaped shell cage is difficult to take out due to too much impurities attached by the lubricating oil, which causes the adhesion between the bell-shaped shell cage and the lower die seat 24 to be too large, can be avoided, at this time, the operator can manually take out or take out the bell-shaped shell cage through the setting of the mechanical hand.

[0057] When the brush 457 is needed to remove the lubricating oil or the residual iron filings of the stamping spline attached to the closed end of the bell housing cage, the mechanical arm for transporting the bell housing cage can place the closed end of the bell housing cage in the designated cleaning area, and make the closed end of the bell housing cage abut against the open end, that is, the shoulder of the bell housing cage and the driving plate 463, then adjust the position of the bell housing cage in the length direction of the rack 454, at this time, the first adjusting rod 461 and the second adjusting rod 462 are relatively displaced, so as to adjust the height of the driving plate 463, then the moving driving plate 463 can abut against and press the driving piece 458, since the bottom of the rack 454 and the sliding seat 452 are connected through the supporting spring 455, and then in the process of pressing the driving piece 458, the rack 454 can move in the length direction of the longer end of the L-shaped sliding seat 452, the moving rack 454 can drive the gear 453 engaged with it to rotate, and then can drive the brush 457 connected with the gear 453 to rotate, and then complete the cleaning work at the spline position of the closed end of the bell housing cage, at the same time, in the cleaning process, the rotating seat 44 can rotate, and cooperate with the pressing work of the mechanical arm, so that the brush 457 can simultaneously brush the closed end of the bell housing cage in the axial and circumferential directions, and at the same time, through the rack 454 and the gear 453 arranged, the brush 457 can rotate, and then the iron filings attached to the bell housing cage can be removed, and the spline work of the bell housing cage frame can be smoothly carried out.

[0058] The working principle is explained: when the clock shell ball cage is placed in the specified position by artificial or mechanical hand during the processing work of the clock shell ball cage, the upper die seat 22 is adjusted by the punch 21, and the clock shell ball cage is processed by the punch on the upper die seat 22. When the clock shell ball cage needs to be separated from the lower die seat 24, the gas is injected into the air inlet pipe 2712, and the gas can be discharged from the air outlet pipe 2713 because the two cavities are connected by the connecting channel. Because the outlet end of the air outlet pipe 2713 is connected with the air outlet 26, and the air outlet 26 is located in the opening end, the clock shell ball cage is separated from the lower die seat 24 by discharging gas into the opening end of the clock shell ball cage. When the impurities attached by the lubricating oil are too much, and the clock shell ball cage is extruded during the stamping, the adhesion between the lower die seat 24 and the clock shell ball cage becomes larger, and the above method is difficult to separate the clock shell ball cage from the lower die seat 24. At this time, the driving motor 272 rotates, and the rotating driving motor 272 can drive the rotating wheel 273 to rotate, so that the pushing rod on the rotating wheel 273 and the farthest contact point from the cam center respectively abut against the first driving rod 274 and the second driving rod 277, so as to drive the first driving rod 274 and the second driving rod 277 to move, so as to adjust the position of the limiting block 275 and the driving block 278 in the respective cavities, so as to make the limiting block 275 and the driving block 278 away from the rotating wheel 273. The driving block 278 moves through the second spring 279, so as to drive the driven block 2710 to move, so as to make the limiting ball 2711 block the air inlet of one of the air outlet pipes 2713, so as to make the blowing device 27 have only one air outlet 26. At this time, the demolding work of the clock shell ball cage can be completed.

[0059] When the clock shell ball cage needs to be centered and limited in the closed end of the lower die seat 24, the limiting cylinder starts to work, and the moving limiting cylinder drives the connecting limiting member to work, so that the limiting member can move on the limiting slide rail 258, and the limiting wheel 254 can abut against the surface of the clock shell ball cage. In this process, the connecting rod 253 in the limiting member also drives the driving wheel 255 to move, so as to adjust the position of the driving wheel 255 in the waist-shaped hole, so as to drive the remaining driving wheel 255 to move, so that all the limiting wheels 254 abut against the surface of the clock shell ball cage, and the centering and clamping limiting work of the clock shell ball cage is completed.

[0060] Through the cooperation of the first cylinder mechanism 31 and the second cylinder mechanism 36, the position of the rotary manipulator 37 in the length direction of the first cylinder mechanism 31 and the second cylinder mechanism 36 is adjusted, and then the height of the rotary manipulator 37 is adjusted through the lifting cylinder 33. Through the cooperation of the above structures, the position of the rotary manipulator 37 can be changed, so that the rotary manipulator 37 can complete the clamping and carrying work of the ball cage of the bell-shaped shell. After the ball cage of the bell-shaped shell is placed at a predetermined position through the rotary manipulator, the position of the rotary manipulator is adjusted, the clamping position of the ball cage of the bell-shaped shell by the rotary manipulator is changed, and then the rotary manipulator 37 is rotated to make the closed end of the ball cage of the bell-shaped shell face the ground, and then the ball cage of the bell-shaped shell is carried to a predetermined cleaning area.

[0061] When cleaning, water is injected into the water inlet pipe 42, so that the cleaning liquid is sprayed from the spray head 43, and the surface of the ball cage of the bell-shaped shell in the cleaning area can be cleaned. When the bristles 457 are needed to remove the lubricating oil attached to the ball cage of the bell-shaped shell or the iron filings remaining after the stamping spline, the closed end of the ball cage of the bell-shaped shell can be placed in the predetermined cleaning area by the manipulator for carrying the ball cage of the bell-shaped shell, and the closed end of the ball cage of the bell-shaped shell abuts against the opening end, i.e. the shoulder of the ball cage of the bell-shaped shell, and the driving plate 463. Then, the position of the ball cage of the bell-shaped shell in the length direction of the rack 454 is adjusted, and the first adjusting rod 461 and the second adjusting rod 462 are relatively displaced to adjust the height of the driving plate 463. Then, the driving plate 463 in motion can abut against and apply pressure to the driving piece 458. Since the bottom of the rack 454 is connected to the sliding seat 452 through the supporting spring 455, the rack 454 can move in the length direction of the longer end of the L-shaped sliding seat 452 during the extrusion of the driving piece 458. The rack 454 in motion can drive the gear 453 engaged therewith to rotate, and then drive the bristles 457 connected to the gear 453 to rotate, thereby completing the cleaning work at the spline position of the closed end of the ball cage of the bell-shaped shell. At the same time, during the cleaning process, the rotating seat 44 can be rotated, and the bristles 457 can be brushed in the axial and circumferential directions of the closed end of the ball cage of the bell-shaped shell through the pressing work of the manipulator. At the same time, through the rack 454 and the gear 453, the bristles 457 can rotate, thereby removing the iron filings attached to the ball cage of the bell-shaped shell, and ensuring the smooth spline work of the ball cage of the bell-shaped shell.
