Description

Technical Field

[0001] This application relates to the field of bearing processing equipment technology, and in particular to a rolling device and rolling method for the outer sleeve of radial spherical plain bearings. Background Technology

[0002] With the development of machinery manufacturing and bearing production technology, a processing technology for the outer sleeve of radial spherical plain bearings has emerged. This technology is mainly used to produce seamless radial spherical plain bearings. Its characteristic is that it can achieve a good fit between the bearing outer sleeve and the radial steel balls through specific processing steps, thereby improving the overall performance and service life of the spherical plain bearing.

[0003] In related technologies, the processing of the outer sleeve of a radial spherical plain bearing typically includes a pressing process and subsequent rolling. After the pressing process, traditional methods often employ manual or semi-automatic rolling to release the contact stress between the outer sleeve and the steel balls. However, this method is not only inefficient, but also has limited control precision in the rolling process, making it difficult to ensure that each rolling operation achieves the desired stress release effect.

[0004] The traditional rolling method described above suffers from low automation, which not only affects production efficiency but may also lead to poor fit between the bearing outer sleeve and the steel ball due to uneven rolling, thereby affecting the overall performance and service life of the spherical plain bearing.

[0005] Therefore, it is necessary to develop a rolling device and rolling method for the outer sleeve of a radial spherical bearing to solve the problems existing in the prior art. Summary of the Invention

[0006] Therefore, it is necessary to provide a roller pressing device and method for radial spherical plain bearings to address the above problems, thereby automating the roller pressing of radial spherical plain bearings, achieving high work efficiency, and realizing ideal stress relief effect.

[0007] A device for rolling a radial spherical bearing outer sleeve, comprising:

[0008] The unloading mechanism is used to store and output the radial spherical bearing workpieces to be processed;

[0009] The feeding mechanism is located downstream of the discharging mechanism and is used to receive the workpieces output by the discharging mechanism and to transport the workpieces to the rolling station in a step-by-step manner.

[0010] A rolling mechanism is located downstream of the feeding mechanism and includes a rolling station where the workpiece is rolled.

[0011] The receiving mechanism, located downstream of the rolling mechanism, is used to collect the workpieces processed by the rolling mechanism.

[0012] In one embodiment, the discharge mechanism includes: a waiting bin for storing radial spherical bearing workpieces, a pusher plate disposed inside the waiting bin for pushing the workpieces to the discharge port, and the workpieces then rolling along the feed trough to the feeding mechanism.

[0013] In one embodiment, the bottom of the pusher plate is connected to the output end of the pusher cylinder, and the pusher cylinder drives the pusher plate to push the workpiece to the discharge port at the top of the material bin; after the workpiece reaches the discharge port at the top of the material bin, it rolls along the length of the material trough due to its own weight.

[0014] In one embodiment, the feeding mechanism includes a bracket, a first material-supporting cylinder, a second material-supporting cylinder, a transverse cylinder, and a material-supporting rod; the material-supporting rod passes through multiple workpieces to provide auxiliary support, the first material-supporting cylinder and the second material-supporting cylinder move up and down synchronously to lift or lower the workpieces, and the transverse cylinder pushes the bracket to make the workpieces move laterally and reach the rolling station.

[0015] In one embodiment, the feeding mechanism further includes rollers, which are disposed above the bracket and in contact with the upper surface of the bracket. Under the action of the transverse cylinder, the rollers roll synchronously when the bracket moves transversely.

[0016] In one embodiment, the feeding mechanism further includes a return cylinder, which is used to push the support rod to reset, so that the workpiece in the material trough can be re-passed onto the support rod.

[0017] In one embodiment, the rolling mechanism includes a base, an intermediate platform is provided on the top of the base, and the intermediate platform is fixedly assembled with the upper frame by a vertical column to form the overall outer frame of the rolling mechanism 3.

[0018] In one embodiment, a downward pressure drive mechanism is installed on the upper frame, and the output end of the downward pressure drive mechanism is connected to the upper roller, which is arranged opposite to the lower roller below.

[0019] In one embodiment, the structure of the downward driving mechanism is a hydraulic cylinder, an electric push rod, or a pneumatic push cylinder;

[0020] When the downward drive mechanism is set as a hydraulic cylinder, a solenoid valve is connected, and the solenoid valve is controlled by the controller, thereby controlling the hydraulic cylinder to perform the downward action;

[0021] When the pressing drive mechanism is set as an electric push rod, an external controller is connected. The controller sends an electrical signal to the electric push rod, causing the electric push rod to perform the pressing operation according to the command of the electrical signal.

[0022] When the downward drive mechanism is set as a pneumatic push cylinder, an external controller is connected. The controller sends an electrical signal to the pneumatic push rod, causing the pneumatic push rod to perform downward pressing operations according to the command of the electrical signal.

[0023] In one embodiment, the receiving mechanism includes a receiving frame and a receiving bucket, the receiving bucket being fixed on the receiving frame for receiving and collecting the processed workpieces output from the feeding mechanism.

[0024] A method for rolling the outer sleeve of a radial spherical plain bearing involves using a radial spherical plain bearing outer sleeve rolling device to roll the radial spherical plain bearing workpiece. The process includes workpiece preparation, automatic feeding, step feeding, rolling processing, and workpiece collection, thereby rolling the outer sleeve of the radial spherical plain bearing workpiece.

[0025] The specific process of the roller pressing is as follows:

[0026] Workpiece preparation: Place the radial spherical plain bearing workpieces that have undergone the pressing process into the waiting bucket;

[0027] Automatic feeding: The pushing cylinder pushes the pushing plate upward, lifting the radial spherical bearing workpiece to the discharge port of the waiting bucket. The workpiece rolls into the discharge trough under the action of gravity.

[0028] The feeding mechanism is raised after the upper roller completes one rolling operation according to the set parameters. The first and second supporting cylinders on the bracket rise synchronously to lift the workpiece on the supporting rod. Under the push of the transverse cylinder, the bracket moves to the right to the processing position. Then, the first and second supporting cylinders descend synchronously. The workpiece on the supporting rod is located between the upper and lower rollers at the rolling station, ready for rolling.

[0029] In the roll forming process, the downward pressure drive mechanism works to drive the upper roller to move downward and press the workpiece for roll forming. By adjusting the rolling time and pressure of the upper roller, the stress release effect is ensured.

[0030] After the workpiece is collected and rolled, the output end of the lower pressure drive mechanism is reset, the upper roller is raised, and the feeding mechanism repeats the cyclic step feeding action so that the processed workpiece falls into the collection bucket from the drop port at the end of the second support plate.

[0031] The aforementioned radial spherical plain bearing outer sleeve rolling device and rolling method have several advantages. First, the highly automated processing significantly improves production efficiency and reduces labor costs. Second, the design of the rolling mechanism ensures the uniformity and stability of the rolling process, effectively improving the machining accuracy and surface quality of the workpiece. Furthermore, the coordinated operation of the discharge and feeding mechanisms enables continuous and stable conveying of the workpiece, avoiding problems such as workpiece accumulation or insufficient supply. Finally, the entire device is compact, fully automated, easy to operate, and easy to maintain and repair, reducing long-term operating costs. Attached Figure Description

[0047] See Figure 1 , Figure 1 A schematic diagram of the structure of a roller pressing device according to an embodiment of the present application is shown. The roller pressing device for the outer sleeve of a radial spherical bearing provided in an embodiment of the present application includes a discharge mechanism 1, a feeding mechanism 2, a roller pressing mechanism 3, and a receiving mechanism 4.

[0048] The feeding mechanism 2 is located downstream of the discharging mechanism 1, and the rolling mechanism 3 is located downstream of the feeding mechanism 2. The feeding mechanism 2 transports the workpiece to the rolling station of the rolling mechanism 3, and the receiving mechanism 4 is set at the end of the feeding mechanism 2.

[0049] Combination Figure 2 As shown, Figure 2 A diagram showing the transport route of a bearing in the rolling process according to an embodiment of this application is illustrated.

[0050] In some embodiments, the discharge mechanism 1 is used to store and automatically output the radial spherical bearing workpiece to be processed, including a discharge frame 101, a waiting bucket 102, a pusher cylinder 103, a pusher plate 104 and a material trough 105.

[0051] The material storage bin 102 is fixed to the top of the discharge frame 101 and is used to store the workpieces to be processed. In a specific embodiment, the material storage bin 102 adopts a sloping bottom design, which makes it easy for the workpieces to automatically gather towards the discharge port due to gravity.

[0052] The top output end of the pusher cylinder 103 is connected to the pusher plate 104, which is located inside the waiting hopper 102.

[0053] The pusher cylinder 103, in conjunction with the pusher plate 104, pushes the workpiece to the discharge port. The workpiece then rolls along the length of the material trough 105 to the feeding mechanism 2. One end of the material trough 105 is connected to the discharge port of the waiting bucket 102.

[0054] In one specific embodiment, the discharge mechanism 1 further includes a sensor (not shown in the figure). The sensor is disposed on the material trough 105 and is used to detect the number of workpieces in the material trough 105. When the material trough 105 is detected to be full, the sensor sends a signal to control the pusher cylinder 103 to stop operating, so as to avoid excessive accumulation of workpieces.

[0055] In some embodiments, the feeding mechanism 2 is used to receive the workpiece output from the discharging mechanism 1 and convey it stepwise to the designated rolling station; the feeding mechanism 2 includes a bracket 201, a first material-supporting cylinder 202, a second material-supporting cylinder 204, a transverse cylinder 206, a roller 207, a material-supporting rod 208, and a return cylinder 209.

[0056] The step-feeding process includes: the first material support cylinder 202 and the second material support cylinder 204 are raised synchronously, the transverse cylinder 206 drives the bracket 201 to move horizontally to the roller pressing station, and after moving into place, the first material support cylinder 202 and the second material support cylinder 204 are lowered synchronously, and the roller pressing mechanism 3 performs roller pressing operation on the bearing workpiece in the roller pressing station.

[0057] After the roller pressing is completed, the return cylinder 209 pushes the material support rod 208 to reset and passes through the bearing workpiece located at the end of the material trough 105; the transverse cylinder 206 drives the bracket 201 to reset, the first material support cylinder 202 and the second material support cylinder 204 are raised synchronously again, the transverse cylinder 206 drives the bracket 201 to move horizontally, at this time the workpiece located on the roller pressing station is removed, and the workpiece in the previous station is sent into the roller pressing station;

[0058] Repeat the step-by-step conveying process described above until all workpieces have been processed.

[0059] Among them, bracket 201 is used to support components such as material support cylinder and maintain their stability.

[0060] The first material support cylinder 202 and the second material support cylinder 204 are respectively located at both ends of the bracket 201, and the top of the bracket is respectively provided with a first material support plate 203 and a second material support plate 205.

[0061] Among them, the material support rod 208 passes through the axis of the workpiece as a reference, and multiple workpieces are strung together on the material support rod 208 to play the role of auxiliary support for the workpiece; at the same time, under the push of the transverse cylinder 206, the bracket 201 and the workpiece move laterally.

[0062] The roller 207 is positioned above the bracket 201 and contacts the upper surface of the bracket 201. The roller 207 and the bracket 201 roll and rub against each other to reduce the frictional resistance when the bracket 201 moves laterally.

[0063] The return cylinder 209 is positioned opposite the end of the material support rod 208 that is away from the discharge mechanism 1. It is used to push the material support rod 208 to reset, so that the workpiece in the material trough 105 can be re-passed onto the material support rod 208.

[0064] Combination Figure 3 As shown, Figure 3 A schematic diagram of the roller pressing mechanism 3 in one embodiment of this application is shown.

[0065] In some embodiments, the rolling mechanism 3 includes a rolling station where the workpiece is precisely rolled to optimize its performance. The rolling mechanism 3 includes a base 301, an intermediate platform 302 is provided on the top of the base 301, the intermediate platform 302 is fixedly assembled with the upper frame 304 by a vertical column 303 to form the overall outer frame of the rolling mechanism 3; it also includes a lower pressing drive mechanism 305, an upper rolling roller 306, a lower rolling roller 307, a gearbox 308 and a drive motor 309.

[0066] The pressing drive mechanism 305 is mounted on the upper frame 304, and the output end of the pressing drive mechanism 305 is connected to the upper roller 306.

[0067] The lower roller 307 is connected to the drive motor 309 via a gearbox 308 to achieve rotation.

[0068] When the workpiece is conveyed to the rolling station, the downward driving mechanism 305 works, pushing the upper roller 306 to move downward, and together with the lower roller 307 below, rolls the workpiece.

[0069] In some embodiments, the pressing drive mechanism 305 can be a hydraulic cylinder for pressing, an electric push rod for pressing, or a pneumatic push rod for pressing.

[0070] In one specific embodiment, the pressing drive mechanism 305 is configured as a hydraulic cylinder, and a solenoid valve is added to the pipeline of the hydraulic cylinder. The solenoid valve receives the electrical signal command from the controller, thereby controlling the hydraulic cylinder to perform the pressing action.

[0071] In one specific embodiment, the pressing drive mechanism 305 is configured as an electric push rod, which is externally connected to a controller. The controller sends an electrical signal to the electric push rod, causing the electric push rod to perform a pressing operation according to the command of the electrical signal sent by the controller.

[0072] In one specific embodiment, the pressing drive mechanism 305 is configured as a pneumatic push rod, which is externally connected to a controller. The controller sends an electrical signal to the pneumatic push rod, causing the pneumatic push rod to perform a pressing operation according to the command of the electrical signal sent by the controller.

[0073] The controller is used to realize intelligent control of the pressing drive mechanism 305. Its control steps are as follows: input the required technical requirements for roller pressing and loosening → after the machine starts working, the loosening state is detected in real time by the sensor → the signal is fed back to the PLC module of the controller → send the command to the pressing drive mechanism 305 → execute the pressing action, which includes pressing pressure control and displacement adjustment control → the sensor continues to detect the new roller pressing and loosening state until the set technical requirements are met.

[0074] In one specific embodiment, the drive motor 309 drives the lower roller 307 to rotate through the gearbox 308, ensuring that the rolling process is uniform and stable.

[0075] In some embodiments, the receiving mechanism 4 includes a receiving frame 401 and a receiving bin 402.

[0076] The receiving bin 402 is fixed to the receiving frame 401 and is used to receive the processed workpieces output from the feeding mechanism 2. The receiving mechanism 4 is located at the discharge port at the end of the feeding mechanism 2, which can ensure that the processed workpieces are collected in an orderly manner, facilitating subsequent processing or packaging.

[0077] In some embodiments, the method for rolling the outer sleeve of the radial spherical bearing of this application is as follows:

[0078] Workpiece preparation: Place the radial spherical plain bearing workpiece that has undergone the pressing process into the waiting bin 102; further, the waiting bin 102 has a sloping bottom structure;

[0079] Automatic feeding: The pusher cylinder 103 pushes the pusher plate 104 upward, and the inclined surface design lifts the radial spherical bearing workpiece to the discharge port. The workpiece rolls into the discharge trough 105 under the action of gravity. For example, the discharge mechanism 1 also includes a sensor (not shown in the figure). The sensor detects whether the trough 105 is full, thereby controlling the pushing action. When the sensor detects that the trough 105 is full, the pushing mechanism stops to avoid excessive accumulation.

[0080] Step-feeding: According to the set parameters, the feeding mechanism 2 lifts up after the upper roller 306 completes one rolling operation; the first supporting cylinder 202 and the second supporting cylinder 204 on the bracket 201 rise synchronously, lifting the workpiece on the supporting rod 208, and under the push of the transverse cylinder 206, the bracket 201 moves to the right to the processing position. Subsequently, the first supporting cylinder 202 and the second supporting cylinder 204 descend synchronously, and the workpiece on the supporting rod 208 is located in the rolling station, between the upper roller 306 and the lower roller 307, ready for rolling.

[0081] Roll forming: The downward pressure drive mechanism 305 drives the upper roller 306 to move downward and press the workpiece for rolling; for example, the rolling time and pressure of the upper roller 306 can also be adjusted by the control system to ensure stress release effect;

[0082] Workpiece collection: After the rolling is completed, the output end of the lower pressure drive mechanism 305 is reset, the upper roller 306 is raised, and the feeding mechanism 2 repeats the cyclic step feeding action so that the processed workpiece falls into the collection bucket at the drop port at the end of the second support plate 205 for subsequent processing.

[0083] In the rolling method of this application, in addition to the step feeding method described above, preferably, the support rod 208 and the lower roller 307 can also have a taper that tends towards the discharge direction from the feeding direction. The two parallel lower rollers 307 rotate in the same direction. The workpiece to be processed on the support rod 208 automatically slides down to the processing position in front of the upper roller 306 and the lower roller 307 due to the taper of the support rod 208. Then, the workpiece to be processed enters between the upper roller 306 and the lower roller 307 and is rolled. Under the influence of the taper of the lower roller 307, it automatically moves towards the discharge direction. In this way, the position of the upper roller 306 is preset and fixed according to the size of the workpiece to be processed. In this feeding method, the upper roller 306 plays the role of assisting in rolling the workpiece and assisting in driving the workpiece to move towards the receiving mechanism 4. In this method, the bracket 201 and the support rod 208 no longer need to feed by repeatedly rising and moving laterally, which improves the working efficiency.

[0084] The radial spherical bearing outer sleeve rolling device and rolling method of this application significantly improve production efficiency and reduce labor costs through a highly automated processing flow; by utilizing the coordinated work of the discharge mechanism 1 and the feeding mechanism 2, continuous and stable conveying of workpieces is achieved, avoiding the problems of workpiece accumulation or insufficient supply; the entire device of this application has a compact structure, integrated automation, simple operation, easy maintenance and upkeep, and reduces long-term use costs.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
