[0002] As one of the most basic parts for transmitting motion and power, shaft parts have been widely used in many industrial fields such as automobiles, rail transportation, ships, and engineering machinery. Since plastic forming has the advantages of improving organizational properties, increasing material utilization, and high production efficiency, shaft parts are mostly produced using plastic forming technology.

[0003] A two-roller flexible oblique rolling forming device and method for shaft parts is disclosed in the patent with announcement number CN110102575B. When in use, the blank needs to be passed through the first material guide barrel and the second material guide barrel to prevent the blank from swinging during the rolling process. However, since the diameters of the first material guide barrel and the second material guide barrel are fixed, the first material guide barrel and the second material guide barrel can only limit the blank of fixed diameter. Utility Model Content

[0004] The purpose of this application is to propose a shaft rolling equipment in view of the above-mentioned problems existing in the prior art.

[0005] The present application can be implemented through the following technical solution: a shaft rolling equipment, including a frame, a disc, a clamping claw, a fixing component, a roller, a motor and an electric push rod. The disc is fixedly connected to the frame, and a through hole is formed through the disc along its thickness direction, and the through hole is used to penetrate the shaft body; the claw is slidably connected to the disc, and the claws are provided with a plurality of claws and the plurality of claws can slide along the radial direction of the disc, and the shaft body can be accommodated between the plurality of claws, and the plurality of claws are arranged in the through hole; the fixing assembly is used to fix the claws at different positions of the disc, so that shaft bodies of different diameters can be accommodated between the plurality of claws; the roller can contact the axial outer wall of the shaft body, and a roller is provided on both sides of the axis direction of the shaft body; the motor 1 is used to drive the roller to rotate around its own axis, and the two rollers have the same rotation direction; the electric push rod 1 is used to drive the roller to move linearly along the radial direction of the shaft body, so that the roller contacts or moves away from the shaft body; wherein, the disc is provided with a plurality of and is coaxially installed, and the plurality of through holes are used to penetrate the same shaft body, and the roller is located between the plurality of discs.

[0006] In the above technical solution, when the shaft needs to be rolled, the position of the claws is first adjusted according to the diameter of the shaft, and then the claws are fixed to the disc through a fixing assembly, and then the shaft is inserted into several holes and the shaft is located between several claws of each disc, and then the roller is driven to move along the radial direction of the shaft through an electric push rod, so that the roller can contact the shaft, and then the motor is turned on to drive the roller to rotate around its own axis. Since the two rollers rotate in the same direction, the shaft will rotate with the roller, and the roller can roll a step on the shaft. During the rolling process of the shaft, the area enclosed by several claws can guide the movement path of the shaft, and can also reduce the swing of the shaft during rotation, thereby ensuring the quality of the shaft after rolling.

[0007] Furthermore, the fixing assembly includes a bolt and a nut. The nut can be threadedly connected with the bolt; wherein the disc is provided with a plurality of adjustment slots along its thickness direction, the length directions of the plurality of adjustment slots correspond to and coincide with the length directions of the plurality of claws, the bolt can be sequentially passed through the claws and the adjustment slots, and the nut can abut against the end face of the disc away from the claw.

[0008] In the above technical solution, after the worker moves the claw to the desired position, the bolt can be inserted into the claw and the adjustment groove in turn, and then the nut can be threadedly connected to the bolt. At this time, the nut abuts against the end face of the disc away from the claw. At this time, the position of the claw can be fixed relative to the disc. Several claws on the same disc can be operated in this way, and the claws can be fixed at different positions of the disc, so that shafts with different diameters can be accommodated between the several claws, and the scope of application is wide.

[0009] Furthermore, it also includes a spring that can force the claw to move away from the center of the disk, wherein several claws on the same disk are each provided with a hole, and the several holes are used to pass the same rope, and the rope is pulled to make several claws approach or move away from the center of the disk at the same time.

[0010] In the above technical solution, by pulling the rope, several claws can move close to the center of the disk at the same time. When the claws are at the required position, stop pulling the rope, and then fix the claws on the disk through the fixing assembly. It is convenient to determine the positions of multiple claws at the same time by only pulling the rope.

[0011] Furthermore, it also includes a pull rod, and several ropes can be simultaneously sleeved on the pull rod.

[0012] In the above technical solution, several ropes can be simultaneously sleeved on the pull rod. By pulling the pull rod, the several ropes can drive the several claws on each disc to move close to the center of the disc at the same time, so that the projections of the areas enclosed by the several claws on the two discs on the same vertical plane coincide with each other, so that after the shaft body is placed between the several through holes, the axis of the shaft body is horizontal relative to the ground, thereby ensuring the rolling quality of the shaft body.

[0014] In the above technical scheme, when the shaft body needs to be processed with a longer variable section, the worm can be driven to rotate by motor 2, so that the rotation of the worm drives the mounting seat to rotate through the worm gear, so that the roller can deflect in a straight line perpendicular to its own axis, so that the two rollers are arranged in a staggered manner. When the two rollers are arranged in a staggered manner and the rollers rotate around their own axes, there is a feed angle for the shaft body, so that the shaft body can move forward in a spiral manner. The oblique rolling method is used to roll the shaft body with a longer variable section, which has the advantages of good product surface quality and high efficiency.

[0015] Furthermore, it also includes an electric push rod 2 for driving the shaft body to move linearly along its own axial direction.

[0016] In the above technical solution, the rolling speed of the shaft body can be accelerated and the rolling efficiency can be improved by driving the shaft body to move linearly along its own axial direction through the second electric push rod.

[0017] Furthermore, a plurality of telescopic sleeves are provided in the spring, and the telescopic sleeves can contact the axial inner wall of the spring.

[0018] In the above technical solution, the telescopic sleeve can limit the radial displacement of the spring to reduce the possibility of the spring axis being skewed due to external force, thereby extending the service life of the spring.

[0019] Furthermore, the claw is located at an end of the disc facing away from the roller.

[0020] In the above technical solution, flying chips are generated during the rolling process. By arranging the claws at the end of the disc away from the roller, the possibility of the flying chips flying into the inside of the spring during the rolling process can be reduced, thereby extending the service life of the equipment.

[0021] In summary, the present application has the following technical effects: when the shaft needs to be rolled, first adjust the position of the claws according to the diameter of the shaft, then fix the claws on the disc through a fixing assembly, then insert the shaft into several insertion holes and make the shaft between several claws of each disc, then drive the rollers to move along the radial direction of the shaft through an electric push rod, so that the rollers can contact the shaft, then turn on the motor to drive the rollers to rotate around their own axes, and since the two rollers rotate in the same direction, the shaft will rotate with the rollers, and at this time the rollers can roll steps on the shaft. During the rolling process of the shaft, the area enclosed by several claws can guide the movement path of the shaft, and can also reduce the swing during the rotation of the shaft, thereby ensuring the quality of the shaft after rolling.

A roller 5 is placed above and below the shaft body, and the roller 5 is located between the two discs 2. The axis of the roller 5 is parallel to the ground, and the axial outer wall of the roller 5 can contact the axial outer wall of the shaft body.

The truncated cone end 52 can contact the axial outer wall of the shaft body to roll an oblique step on the shaft body. The area enclosed by the five claws 3 can guide the movement of the shaft body and reduce the swing of the shaft body during rolling. There is a gap between the claws 3 and the axial outer wall of the shaft body so that the shaft body can be rolled more smoothly.

The two mounting plates 17 are placed horizontally, and the fixed ends of the two electric push rods 17 are fixedly mounted on the frame 1. The rotation axis of the mounting seat 11 is perpendicular to the ground, and the plate is rotatably connected to a worm 13. A worm wheel 12 is fixedly mounted on the vertical side wall of the mounting seat 11, and the worm wheel 12 can mesh with the worm 13. The worm 13 is driven to rotate by a motor 2 14, so that the rotation of the worm 13 can drive the roller 5 to deflect with a straight line perpendicular to the ground as the axis through the worm wheel 12 and the mounting seat 11.
