Description

Technical Field

[0001] This utility model relates to the field of bearing cage technology, and in particular to an inner groove pressing and forming device for producing needle roller bearing cages. Background Technology

[0002] The cage of a needle roller bearing needs to have beveled grooves to mount the needle rollers. These grooves enhance the stability of the needle rollers and reduce friction and wear. The raw material blank of the cage is a round tube. The general processing method is to fix the raw material blank horizontally and then make horizontal grooves by the grooving component. Although the cage is made of stainless steel and is hard, horizontal grooving will cut off the continuous force path of the metal tube, reduce its compressive and bending resistance, and may damage the sealing and structural stability. Utility Model Content

[0003] The purpose of this application is to provide an inner groove pressing and forming device for the production of needle roller bearing cages, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: A groove pressing and forming device for producing needle roller bearing cages includes a worktable and a forming assembly mounted on the worktable. A functional plate is fixedly installed above the worktable surface. The forming assembly includes a rotating plate, a bonding plate, and a lifting plate. The lifting plate is movably installed between the worktable and the functional plate. A circular hole is formed in the center of the functional plate surface. The rotating plate is rotatably installed inside the circular hole. Two bonding plates are symmetrically arranged at the center of the rotating plate and are movably mounted on the rotating plate. The rotating plate is movably mounted on the lifting plate. A screw rod is mounted on the bottom surface of the rotating plate via a bearing. The screw rod is a double-ended screw rod. The bottoms of the two bonding plates are threaded to the two sides of the screw rod. A groove is formed on the surface of the rotating plate. An extension rod is fixedly installed on the bottom of the bonding plate, and the end of the extension rod is embedded in the groove.

[0005] Preferably, a second screw is provided between the workbench and the functional board. Both ends of the second screw are connected to the workbench and the functional board respectively via bearings. A first motor is fixedly installed on the workbench surface, and the second screw is driven by the first motor. One end of the lifting plate is threadedly connected to the second screw. A guide rod is fixedly installed between the workbench and the functional board, and one end of the lifting plate is sleeved on the outside of the guide rod. A driven wheel is mounted on the surface of the lifting plate via bearings. A driving wheel is mounted on one side of the driven wheel via a meshing tooth. A second motor is fixedly installed on the bottom outer wall of the lifting plate, and the driving wheel is driven by the second motor. The bottom surface of the functional board is fixedly connected to the driven wheel.

[0006] The beneficial effects of this utility model are: by setting a molding component, the horizontal grooving is changed to vertical grooving, and the grooving component is automatically raised, lowered and rotated on the rotating plate. The grooving component only needs to be fixed, and the remaining steps are automatically completed by the molding component. Attached Figure Description

[0010] like Figure 1-4 The device shown is an inner groove pressing and forming device for producing needle roller bearing cages. It includes a worktable 1 and a forming assembly mounted on the worktable 1. A functional plate 2 is fixedly installed above the worktable 1. The forming assembly includes a rotating plate 4, bonding plates 5, and a lifting plate 14. The lifting plate 14 is movably installed between the worktable 1 and the functional plate 2. A circular hole is formed at the center of the functional plate 2. The rotating plate 4 is rotatably installed inside the circular hole. Two bonding plates 5 are symmetrically arranged at the center of the rotating plate 4 and are movably installed on the rotating plate 4. The rotating plate 4 is movably installed on the lifting plate 14. A screw 7 is mounted on the bottom surface of the rotating plate 4 via a bearing. The screw 7 is a double-ended screw. The bottoms of the two bonding plates 5 are threaded to the two sides of the screw 7, respectively. A groove 6 is formed on the surface of the rotating plate 4. An extension rod 10 is fixedly installed at the bottom of the bonding plate 5, and the end of the extension rod 10 is embedded inside the groove 6.

[0011] A screw 8 is installed between the workbench 1 and the function plate 2. Both ends of the screw 8 are connected to the workbench 1 and the function plate 2 respectively via bearings. A motor 3 is fixedly installed on the surface of the workbench 1, and the screw 8 is driven by the motor 3. One end of the lifting plate 14 is threadedly connected to the screw 8. A guide rod 9 is fixedly installed between the workbench 1 and the function plate 2, and one end of the lifting plate 14 is fitted over the guide rod 9. A driven wheel 13 is mounted on the surface of the lifting plate 14 via bearings. A driving wheel 12 is mounted on one side of the driven wheel 13 via a meshing mechanism. A motor 11 is fixedly installed on the bottom outer wall of the lifting plate 14, and the driving wheel 12 is driven by the motor 11. The bottom surface of the function plate 2 is fixedly connected to the driven wheel 13.

[0012] Example: The retainer is placed on the rotating plate 4 at the center of the functional plate 2. The retainer is then fitted onto the two bonding plates 5. The operator then rotates the screw 7. The bonding plates 5 on both sides of the screw 7 unfold together and abut against the inner wall of the retainer, fixing the retainer onto the rotating plate 4. When the bonding plates 5 move, they drive the extension rod 10 to slide in the slide groove 6. The slide groove 6 acts as a guide. The external pressure slope grooving assembly vertically grooves the retainer. The motor 3 drives the screw 8 to rotate. The screw 8 drives the lifting plate 14 to rise and fall between the worktable 1 and the functional plate 2. The lifting plate 14 is guided by the guide rod 9. When the lifting plate 14 rises and falls, it drives the retainer to rise and fall, so that the retainer can use the grooving component to open a vertical groove. After one vertical groove is opened, the motor 11 drives the drive wheel 12 to rotate. The drive wheel 12 drives the driven wheel 13 to rotate. The driven wheel 13 drives the rotating plate 4 to rotate at a certain angle, moving the remaining outer wall of the retainer to the grooving component, and continuing the die casting process.
