Description

Technical Field

[0002] During the machining process of a workpiece with a cage, rolling steel balls need to be installed on the cage to facilitate subsequent rolling support. The methods for installing the steel balls on the cage include: Pocket mounting: The cage has pre-made pockets (such as round or oval) that match the size of the steel ball. The steel ball is directly embedded into the pocket and fixed by slight interference / elastic deformation of the pocket edge. Riveting and welding fixation: Some solid retainers are designed with a retaining edge at the pocket. After steel balls are inserted, the edge is sealed by riveting, welding or other methods to prevent the steel balls from falling out. Snap-fit ​​assembly: The cage adopts a split structure. After steel balls are inserted, they are spliced ​​and fixed by snaps and bolts to form a closed pocket. In the process of installing steel balls on the cage in the above-mentioned manner, the steel ball bearing components need to be pre-installed and processed on the cage before the steel balls are installed.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0018] Please see Figures 1-14 The figure shows a forming mold with a steel ball riveting function, including a base 101 and a top plate 102 disposed above the base 101. The base 101 and the top plate 102 are connected and fixed by multiple sets of mounting rods. The workpiece is placed between the base 101 and the top plate 102. The mold also includes: The mold assembly is set between the base 101 and the top plate 102 for pressing and bending the workpiece. The workpiece includes a plate 201. Forming plates 202 for assisting in pressing and bending are evenly distributed at the four corners of the plate 201. A positioning groove 203 for positioning steel balls is opened between two forming plates 202 on the same side of the plate 201. A feeding assembly is installed on the top plate 102 for feeding and conveying steel balls during the pressing and forming process. A control assembly for controlling the steel ball feeding is installed on the top plate 102. A support component is provided on the mold assembly to support the inner side of the forming plate 202 during the bending and forming process. The mold assembly is provided with a drive component for driving the support component. It should be noted that through the cooperation of the mold assembly, feeding assembly, control assembly, and support assembly, the steel balls are riveted and installed simultaneously during the pressing process of the workpiece in the cage processing, eliminating the need for subsequent installation operations, reducing processes, and ensuring rapid installation and processing of the steel balls on the cage. In addition, during the pressing and bending process, the support assembly supports the inner side of the forming plate 202 during pressing and bending. Through the support, the forming plate 202 fully fits the inner wall of the arc groove 307 during the bending process of the upper mold 306, ensuring the bending radius of the forming plate 202, controlling the inner diameter of the arc cavity, and preventing the riveted steel balls from falling off or getting stuck due to size issues, thus ensuring the installation effect of the steel balls.

[0019] Preferably, the mold assembly includes a support platform 301 disposed above the base 101, a positioning component for assisting in the support and positioning between the support platform 301 and the workpiece, lower molds 302 for supporting the forming plate 202 of the workpiece symmetrically fixed on both sides of the support platform 301, a first cylinder 303 for driving the lifting of the support platform 301 disposed on the base 101, a pressure mold 304 mounted on the top plate 102, two sets of sliding grooves 305 provided on the top plate 102, upper molds 306 slidably connected to the two sets of sliding grooves 305, the two sets of upper molds 306 symmetrically disposed on both sides of the pressure mold 304, a driving component for assisting in the lifting of the upper molds 306 disposed on the top plate 102, and an arc groove 307 for assisting in the pressing and bending of the forming plate 202 disposed at the lower end of the upper mold 306; It should be noted here that after the steel balls are fed and positioned by the feeding and control components, the two sets of upper dies 306 are driven by external drive components to move downward. During the descent, the arc grooves 307 on the two sets of upper dies 306 abut against the ends of the warped forming plates 202. Through the abutment and compression, the forming plates 202 bend to conform to the inner wall of the arc grooves 307. Through the bending of the forming plates 202, an arc cavity adapted to the size of the steel balls is formed between the ends of the two sets of forming plates 202 on the same side, which encloses the steel balls in the positioning grooves 203. This allows the steel balls to be riveted and installed simultaneously during the pressing process of the cage workpiece, eliminating the need for subsequent installation work, reducing the number of steps, and ensuring the rapid installation and processing of steel balls on the cage. In addition, the driving component is a conventional driving component and is known technology in this application. Its working principle and control method will not be described in detail here.

[0020] Preferably, the feeding assembly includes a slot 501 formed above the mold 304, with two sets of slides 502 for assisting in the feeding of steel balls on the inner side of the slot 501, and two sets of discharge holes 503 symmetrically formed on the mold 304. One end of each set of slides 502 is connected to the two sets of discharge holes 503. An installation cavity 504 is formed inside the mold 304, and a control assembly is set inside the installation cavity 504. Two sets of control assemblies are symmetrically arranged inside the installation cavity 504. The control assembly includes a U-shaped slide 601 slidably connected inside the installation cavity 504 for sealing the bottom of the discharge hole 503. A guide groove 602 is formed inside the installation cavity 504 for assisting in guiding the steel balls after they are discharged. The guide groove 602 and the discharge hole 503 are staggered in the vertical direction. A control hole 603 is formed on the U-shaped slide 601 for communicating with the guide groove 602 and the discharge hole 503. It should be noted that after the support platform 301 is pushed upward, the steel ball is picked up inside the mold 304. During the picking process, the required steel balls are first transported to the slot 501 by an external vibrating feeding device. During the transport process, the steel balls are guided by two sets of slide rails 502 to fall into the discharge hole 503 for accumulation. The second cylinder 604 drives the U-shaped slide 601 to slide inside the mounting cavity 504. The sliding of the U-shaped slide 601 connects the control hole 603 with the discharge hole 503. At this time, the steel ball at the bottom of the discharge hole 503 falls into the discharge hole. The steel ball is picked up inside the control hole 603. After the picking is completed, the U-shaped slide 601 is reset by the driving action of the second cylinder 604. During the reset process, the control hole 603 is connected to the guide groove 602 inside the mounting cavity 504. At this time, the steel ball picked up inside the control hole 603 falls into the guide groove 602 under the action of gravity. Through the guiding action of the guide groove 602, the falling steel ball flows to the positioning groove 203 of the plate 201. The positioning groove 203 positions the falling steel ball between the two molding plates 202 on the same side, completing the steel ball dropping, conveying and positioning operation. In addition, the vibratory feeding device is a conventional driving component and is known technology in this application. Its working principle and control method will not be described in detail here.

[0021] Preferably, a second cylinder 604 for controlling the movement of the U-shaped slide 601 is installed inside the mounting cavity 504; It should be noted here that the second cylinder 604 facilitates the movement and driving of the U-shaped slide block 601; In addition, the second cylinder 604 is a conventional drive component and is known technology in this application. Its working principle and control method will not be described in detail here.

[0022] Preferably, two sets of support components are symmetrically arranged on the lower mold 302, and the four sets of support components are respectively arranged in correspondence with the four sets of forming plates 202. The support components include a side plate 701 disposed on one side of the lower mold 302. The side plate 701 and the lower mold 302 are connected and fixed by multiple sets of fixing rods 702. A connecting plate 703 is connected to the side plate 701 by a telescopic component. A support rod 704 for supporting the inner side during the bending process of the forming plate 202 is fixed on the connecting plate 703. It should be noted that during the bending process of the upper mold 306 to form the forming plate 202, the connecting plate 703 under stress moves away from the side plate 701 through transmission. The movement of the connecting plate 703 causes the support rod 704 to be inserted into the inner side of the arc groove 307, supporting the inner side of the forming plate 202 during bending. Through the support, the forming plate 202 is fully in contact with the inner wall of the arc groove 307 during the bending process of the upper mold 306, ensuring the bending radius of the forming plate 202.

[0023] Preferably, the driving assembly includes a driving plate 801 slidably connected to one side of the side plate 701. The driving plate 801 has an inclined groove 802 and a vertical groove 803. The inclined groove 802 is located above the vertical groove 803 and the inclined groove 802 and the vertical groove 803 are connected end to end. A transmission pin 804 is slidably connected to the inclined groove 802. One end of the transmission pin 804 is fixed to the connecting plate 703. An extrusion assembly for extruding the driving plate 801 is provided between the upper die 306 and the driving plate 801. The extrusion assembly includes a mounting pin 901 fixed to the upper end of the driving plate 801. A push plate 902 is fixed to the outside of the upper die 306 for abutting against the end of the mounting pin 901 during the descent. It should be noted that during the bending and forming process of the forming plate 202 by the descent of the upper mold 306, the upper mold 306 moves synchronously, driving the push plate 902 to move synchronously. During the movement of the push plate 902, the push plate 902 abuts against the end of the mounting pin 901 and moves the mounting pin 901 and the drive plate 801 downward. During the downward movement of the drive plate 801, the transmission pin 804 slides sequentially on the vertical groove 803 and the inclined groove 802. During the sliding of the transmission pin 804 inside the inclined groove 802, the abutting and pressing action of the inclined groove 802 on the transmission pin 804 causes the transmission pin 804 and the connecting plate 703 to move under force. During the movement of the connecting plate 703 under force, the sliding guide action of the upper sleeve 1001 and the slide rod 1002 of the telescopic component causes the connected plate 703 to move away from the side plate 701 after being subjected to force.

[0024] Preferably, the telescopic assembly includes multiple sets of sleeves 1001 fixed on the side plate 701, a slide rod 1002 slidably connected to the sleeve 1001, one end of the slide rod 1002 being fixed to the connecting plate 703, and a spring 1003 being sleeved on the outside of the sleeve 1001, with both ends of the spring 1003 being connected to the connecting plate 703 and the side plate 701 respectively. It should be noted here that: multiple sets of sleeves 1001 and slide rods 1002 assist in guiding the extension and retraction of the connecting plate 703 after being subjected to force, and the spring 1003 facilitates the reset of the connecting plate 703 after the extension and retraction movement.

[0025] Preferably, the positioning component includes a mounting groove 401 formed on the plate 201, and a positioning block 402 fixed on the support platform 301 for positioning and engaging with the mounting groove 401; It should be noted here that during the process of installing steel balls on the workpiece in the cage, the workpiece to be processed is placed on the support table 301. During the placement process, the plate 201 is positioned by the interaction between the mounting groove 401 on the plate 201 and the positioning block 402 on the support table 301.

[0026] In this solution: a forming mold with steel ball riveting function includes the following steps: During the process of installing steel balls on the workpiece in the cage machining process, the workpiece to be processed is placed on the support table 301. During the placement process, the installation groove 401 on the plate 201 and the positioning block 402 on the support table 301 are interacted to position the plate 201 during the placement process. Figure 14 In the state where the plate 201 is positioned, the first cylinder 303 drives the support platform 301 and the lower molds 302 on both sides to move toward the pressing mold 304. During the movement, the workpiece plate 201 positioned on the support platform 301 abuts against the bottom of the pressing mold 304. Through the abutting and squeezing action, the workpiece positioned is limited. After the support platform 301 is pushed upward, the steel ball is picked up inside the mold 304. During the picking process, the required steel balls are first transported to the slot 501 by an external vibrating feeding device. During the transport, the steel balls are guided by two sets of slide rails 502 to fall into the discharge hole 503 for accumulation. The second cylinder 604 drives the U-shaped slide 601 to slide inside the mounting cavity 504. The sliding of the U-shaped slide 601 connects the control hole 603 with the discharge hole 503. At this time, the steel ball at the bottom of the discharge hole 503 falls into the control hole 603. Figure 10The process involves retrieving steel balls from the control hole 603 and then resetting the U-shaped slide 601 via the second cylinder 604. During this reset, the control hole 603 connects with the guide groove 602 inside the mounting cavity 504. The steel balls retrieved from the control hole 603 then fall into the guide groove 602 under gravity and are guided by the guide groove 602 to the positioning groove 203 on the plate 201. The positioning groove 203 positions the falling steel balls between the two forming plates 202 on the same side, completing the steel ball delivery and positioning operation. After the steel balls are delivered and positioned, the external... The driving component causes the two sets of upper dies 306 to descend under force. During the descent, the arc grooves 307 on the two sets of upper dies 306 abut against the ends of the warped forming plates 202. Through the abutment and compression, the forming plates 202 bend to conform to the inner wall of the arc grooves 307. Through the bending of the forming plates 202, an arc cavity adapted to the size of the steel ball is formed between the ends of the two sets of forming plates 202 on the same side. The steel ball in the positioning groove 203 is wrapped inside, so that the steel ball can be riveted and installed simultaneously during the pressing of the workpiece in the cage processing. No subsequent installation work is required, reducing the number of processes and ensuring the rapid installation and processing of the steel ball on the cage. During the bending and forming process of the forming plate 202 by the descent of the upper mold 306, the push plate 902 moves synchronously with the movement of the upper mold 306. During the movement of the push plate 902, it abuts against the end of the mounting pin 901, causing the mounting pin 901 and the drive plate 801 to move downwards. As the drive plate 801 is pressed downwards, the transmission pin 804 slides sequentially on the vertical groove 803 and the inclined groove 802. During the sliding of the transmission pin 804 inside the inclined groove 802, the abutting and pressing action of the inclined groove 802 causes the transmission pin 804 and the connecting plate 703 to move under force. During the force-driven movement of the connecting plate 703, the sliding guidance action of the upper sleeve 1001 and the slide rod 1002 of the telescopic assembly causes the force-driven connecting plate 703 to move away from the side plate 701. The movement causes the support rod 704 to insert into the inner side of the arc groove 307, supporting the inner side of the forming plate 202 during pressing and bending. Through the support, the forming plate 202 fully fits the inner wall of the arc groove 307 during the bending process of the upper mold 306, ensuring the bending radius of the forming plate 202, controlling the inner diameter of the arc cavity, and preventing the riveted steel balls from falling off or getting stuck due to size issues, thus ensuring the installation effect of the steel balls. After pressing and bending, the upper mold 306 resets and no longer squeezes the mounting pin 901 and the drive plate 801. At this time, the connecting plate 703 and the support rod 704 reset towards the side plate 701 under the elastic force of the spring 1003 on the telescopic component. Through the reset of the support rod 704, it slides out from the inner side of the bent forming plate 202, avoiding interference with the removal of subsequent processed workpieces, and completing the processing operation of the cage workpiece.
