[0043] The utility model discloses a forming die of a deep groove ball bearing retainer, which is used for processing the ball pocket of the deep groove ball bearing retainer. In addition, the utility model also discloses a processing die of the forming die of the deep groove ball bearing retainer.
[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0045] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.
[0046] A bearing generally consists of four parts: an inner ring, an outer ring, rolling elements and a cage. The inner ring cooperates with the shaft and rotates with the shaft; the outer ring cooperates with the bearing seat and plays a supporting role; the rolling elements are evenly distributed between the inner and outer rings with the help of the cage, and their shape, size and number directly affect the performance and life of the rolling bearing; the cage, also known as the bearing cage or bearing retainer, refers to a bearing part that partially wraps all or part of the rolling elements and moves with them. It is used to isolate the rolling elements, enable the rolling elements to be evenly distributed along the circumference of the bearing and keep the rolling elements in the bearing, and usually guides the rolling elements to rotate for lubrication.
[0047] The shape of the cage of different types of bearings may vary, such as Figure 1 As shown, the cage used for the deep groove ball bearing is generally called a wave-shaped cage, that is, protrusions (or grooves) are processed on the cage to form ball pockets 101 of the rolling body.
[0048] In order to realize machining of protrusions (or grooves) on a cage, the present application discloses a forming die for a deep groove ball bearing cage, by which protrusions (or grooves) can be machined on a flat ring, thereby forming a wavy cage.
[0049] In addition, combined Figure 2 As shown, the present application also discloses a processing die for a deep groove ball bearing retainer, comprising a forming die 2, a shaping die 3 and a punching die 4.
[0050] Among them, the forming mold 2 is used to process the ball pocket 101 on the retaining frame 100 to be processed; the shaping mold 3 is used to shape the ball pocket 101 of the retaining frame 100 processed by the forming mold 2; and the punching mold 4 is used to punch the retaining frame 100 after being shaped by the shaping mold 3.
[0051] The forming die 2, shaping die 3 and punching die 4 in the present application are integrated on the same machine tool, and the same machine tool can be used to simultaneously perform forming, shaping and punching processes on different retaining frames, thereby improving processing efficiency while reducing the use of machine tools, which is beneficial to reducing costs.
[0052] Combination Figures 3 to 10 As shown, the above-mentioned molding die 2 includes a molding upper die 22, a molding lower die 24, a molding core 23 and a stripping assembly.
[0053] The upper molding die 22 has a first die tooth 222; the lower molding die 24 has a second die tooth (not shown in the figure), and the position where the first die tooth 222 is used to fit with the holder to be processed is the same as the shape of the ball pocket, and the position where the second die tooth is used to fit with the holder to be processed is the same as the shape of the ball pocket, which can ensure that when the first die tooth 222 and the second die tooth are against the holder, a ball pocket of a desired shape can be pressed out on the holder. The upper molding die 22 can move relative to the lower molding die 24, and along the moving direction, the first die tooth 222 and the second die tooth are staggered to process a protrusion (or groove) structure on the holder. The forming core 23 is located at the center of the forming lower die 24, and the retaining frame to be processed can be sleeved on the outside of the forming core 23, and the outer diameter of the forming core 23 and the inner diameter of the retaining frame after forming can be loosely matched, so that the inner diameter of the retaining frame is supported by the forming core 23 to prevent the inner diameter of the retaining frame from changing during the stamping process; and under the limiting effect of the protective frame, the position of the retaining frame is prevented from shifting during the stamping process, so as to improve the quality of the retaining frame.
[0054] On the basis of the above technical solution, the upper molding die 22 and the lower molding die 24 are close to each other, and the first die teeth 222 and the second die teeth are used to squeeze the unprocessed retainer located between the upper molding die 22 and the lower molding die 24, and then the molding process of the retainer is completed. However, after the stamping is completed, the position of the retainer on the molding core 23 will be closer to the molding lower die 24, making it more difficult to remove the retainer. Based on this, the molding die in the present application also includes a stripping assembly, and the stripping assembly is used to lift the retainer that is sleeved on the outside of the molding core 23 and has been molded to a preset height in the direction of the upper molding die 22.
[0055] The forming die 2 in the present application uses the first die teeth 222 of the forming upper die 22 and the second die teeth of the forming lower die 24 to punch out an indentation of the desired shape on the retainer to form a protrusion (or groove), and uses the forming core 23 to limit the retainer and the inner diameter size of the retainer, thereby improving the accuracy of the inner diameter of the processed retainer and further improving the quality of the product. The removal assembly can be used to achieve mechanized removal of the retainer, which is conducive to reducing the labor intensity of the operator.
[0056] In some embodiments, the first die 222 and / or the second die have a circular arc surface for contacting with the holder to be processed. The circular arc surface is pressurized with the holder to be processed, thereby forming a protrusion (or groove) on the holder. However, when the circular arc surface is pressed against the holder to be processed, the position of the circular arc surface closest to the holder (the middle position of the protrusion) is likely to form an indentation on the holder, thereby affecting the appearance of the product.
[0057] Based on this, in some embodiments, the first die 222 and / or the second die are used to fit the surface of the retaining frame to be processed, including: a first arc surface 2221, a plane 2222 and a second arc surface 2223 arranged in sequence along the circumferential direction, and the first arc surface 2221 and the second arc surface 2223 are smoothly connected to the side walls of the corresponding sides respectively, and the first arc surface 2221 and the plane 2222, the plane 2222 and the second arc surface 2223 are all smoothly connected.
[0058] It can be understood that the shapes of the first die 222 and the second die in the present application are the same or different. Among them, the first die 222 is used to fit the surface of the holder to be processed, which is the end surface close to one end of the second die, and the middle position of the end surface is a plane 2222, and along the circumferential direction of the upper molding die 22, both sides of the plane 2222 are arc surfaces, and optionally, the first arc surface 2221 and the second arc surface 2223 are symmetrically arranged, and the plane 2222 is smoothly connected to the two arc surfaces, and the two arc surfaces are smoothly connected to the side walls of the first die 222 on the corresponding side in the vertical direction.
[0059] In the present application, the first die teeth 222 and the second die teeth are configured as planes 2222 on one side thereof that are in contact with the retaining frame to be processed. During the stamping process with the retaining frame to be processed, the arc surfaces of the first die teeth 222 and the second die teeth contact the retaining frame to be processed, while the contact position between the plane and the retaining frame to be processed is subjected to little or no force, thereby alleviating the problem of indentations formed by the product plane being squeezed by force, resulting in poor product appearance.
[0060] It should be noted that the problem of using the first die 222 and the second die end faces as arc surfaces causing indentations on the retaining frame to be processed is a problem discovered during the processing process. However, setting the middle position of the end faces of the first die 222 and the second die as a plane and setting the two sides as arc surfaces can effectively alleviate this problem after testing.
[0061] At present, most of the materials used for cage processing are cut-to-size rings, and the sizes of the rings vary greatly. When some rings are used, there are stamping marks on the product appearance, and some rings cannot be produced in different models. By changing the style of the stamping die, the appearance of flat indentations on the product can be avoided, and more specifications of rings can be used to produce the same product, thereby improving the utilization rate of the raw materials and rings of the product.
[0062] The first die tooth 222 disclosed in the present application is an inclined surface for fitting with the to-be-processed retaining frame, and the inclination direction of the inclined surface of the first die tooth 222 is along the direction of the outer radial inner diameter of the molding upper die 22, and the inclined surface of the first die tooth 222 is inclined in the direction away from the second die tooth; and / or, the second die tooth is an inclined surface for fitting with the to-be-processed retaining frame, and the inclination direction of the inclined surface of the second die tooth is along the direction of the outer radial inner diameter of the molding lower die 24, and the inclined surface of the second die tooth is inclined in the direction away from the first die tooth 222.
[0063] In the present application, the first die 222 and the second die are configured as radially inclined structures to produce the desired ball pocket shape on the retainer to be processed. Figure 8 As shown, along the axis direction of the forming mold (the direction in which the forming upper mold 22 and the forming lower mold 24 move relative to each other), the length L2 of the inner diameter end of the first mold tooth 222 and the second mold tooth is smaller than the length L1 of the outer diameter end. The arc of the ball pocket processed by the first mold tooth 222 and the second mold tooth using the above structure is smaller than the arc of the outer diameter side, so that the arc of the inner diameter can be used to limit the rolling body in the ball pocket.
[0064] Those skilled in the art can understand that the shapes and inclination angles of the first die 222 and the second die can be set according to the shape and size of the rolling body, which is not specifically limited here.
[0065] Combination Figure 4 and Fig. 9 As shown, the stripping assembly includes: a forming stripping plate 25 and a driving member 26.
[0066] Among them, the molding stripper plate 25 is sleeved on the outer side of the molding lower mold 24, and is used to push the retaining frame sleeved on the outer side of the molding core 23 and moved toward the molding upper mold 22 after the molding process; the driving member 26 drives the molding stripper plate 25 to move along the molding lower mold 24.
[0067] Optionally, the molding stripper plate 25 has a slot 251 that is clamped on the outside of the second die and can move along the axial direction of the second die. The molding stripper plate 25 is connected to the molding lower die 24 by the cooperation of the slot 251 and the second die; and the movement of the molding stripper plate 25 can be guided by the cooperation of the slot 251 and the second die.
[0068] In some embodiments, the slots 251 are arranged one by one with the second die teeth. The driving member 26 is a spring, and the spring is arranged along the circumference of the molding stripper plate 25 , one end of the spring is fixedly connected to the molding stripper plate 25 , and the other end is fixedly connected to the molding lower die seat 27 .
[0069] It should be noted that the lower forming die base 27 is detachably fixedly connected to the lower die plate 12 of the machine tool, and the lower forming die 24 is detachably mounted on the lower forming die base 27 .
[0070] During the stamping process of the retaining frame to be processed, the forming stripping plate 25 is pushed to move toward the forming lower die 24 under the pressure of the forming upper die 22, and the spring is compressed during this process; after the stamping is completed, the forming upper die 22 moves away from the forming lower die 24, and under the action of the spring restoring force, the retaining frame can be pushed to move toward the forming upper die 22.
[0071] It should be noted that the moving distance of the retaining frame can be set according to the length of the spring. In order to prevent the molding stripper plate 25 from affecting the processing of the retaining frame, the molding stripper plate 25 in the present application is sleeved on the outer side of the molding lower die 24, and during the stamping process, the molding stripper plate 25 can move to the bottom end of the molding lower die 24, and the bottom of the molding lower die 24 is not a position where the second die tooth is set. During the movement, the molding lower die seat 27 can be used to limit the movement of the molding stripper plate 25 to prevent the molding stripper plate 25 from detaching from the molding lower die 24. Based on this, the diameter of the molding lower die seat 27 is greater than the diameter of the bottom end of the molding lower die 24.
[0072] In some embodiments, the molding upper die 22 is a cylindrical structure including a bottom 221 and a first die tooth 222, wherein the bottom 221 and the first die tooth 222 are an integrally molded structure, and there are multiple first die teeth 222, which are evenly arranged along the bottom 221. The structure of the molding lower die 24 in the present application can refer to the structure of the molding upper die 22, and will not be described in detail herein. The molding core 23 is a cylindrical structure.
[0073] The forming upper die 22 in the present application is detachably mounted on the upper die plate 11 of the machine tool via the forming upper die base 21 , so that the forming upper die 22 can be driven by the machine tool.
[0074] Since the molding core, the first die 222 and the second die are all consumable parts, these parts are configured to be detachably connected in the present application to facilitate replacement and reduce processing costs.
[0075] In addition, the present application also discloses a processing mold for a deep groove ball bearing retainer, including a molding mold for the deep groove ball bearing retainer, wherein the molding mold for the deep groove ball bearing retainer is the molding mold for the deep groove ball bearing retainer disclosed in the above-mentioned embodiment. Therefore, the processing mold for the deep groove ball bearing retainer having the molding mold for the deep groove ball bearing retainer also has all the above-mentioned technical effects, which will not be repeated here one by one.
[0076] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0077] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
