Description

Technical Field

[0001] This utility model relates to the technical field of stamping devices, and in particular to a stamping device for bearing rolled edge covers. Background Technology

[0002] Bearing caps, commonly used in miniature bearings, primarily function to protect internal components from dust and other contaminants, while maintaining the seal of the lubricating grease. These caps typically feature a rolled edge design to facilitate a proper fit with the bearing's outer ring, ensuring a tight seal.

[0003] In the existing technology, the rolled edge cover has a complex shape due to its inward rolling edge. This means that the rolled edge of the rolled edge cover is formed by secondary stamping. During the secondary stamping process, the inner wall of the rolled edge cover lacks support, which causes the edge of the rolled edge cover to deform when it rolls inward, thus affecting the production of the rolled edge cover. Utility Model Content

[0004] This application provides a bearing edge-rolling cover stamping device for providing support during edge-rolling cover stamping, thereby solving the problem of deformation affecting the production of edge-rolling covers during edge-rolling cover stamping and folding, thus effectively improving the yield rate of edge-rolling covers and reducing the production cost of edge-rolling covers.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A bearing flange stamping device, comprising:

[0007] The base has a mounting bracket fixedly connected to its top.

[0008] The lower mold is installed on top of the base, and the top of the lower mold has a placement groove for placing the rolled edge cover;

[0009] The upper mold assembly, located above the base, is used to stamp the edge of the rolled edge cover. The upper mold assembly includes an upper template, a slide table, and a support plate. The top of the upper template is connected to the mounting frame via a hydraulic press. A circular hole is opened in the middle of the upper template, and a slide table is slidably connected inside the circular hole. Multiple support plates for supporting the inner wall of the rolled edge cover are arranged in a circular array of the slide table. An angle adjustment unit is provided between the upper template and the support plate. A groove for stamping the rolled edge cover is opened at the bottom of the upper template outside the circular hole.

[0010] Furthermore, the bottom of the slide table is provided with multiple receiving grooves for accommodating the support plate, and the support plate is rotatably connected in the receiving grooves.

[0011] Furthermore, the angle adjustment unit includes a toothed plate and a gear, a gear is provided at the connection between the support plate and the slide, and a toothed plate that meshes with the gear is fixedly connected to the inner wall of the circular hole.

[0012] Furthermore, the outer wall of the slide table is provided with a track groove, and a slider is fixedly connected to the inner wall of the circular hole at the position corresponding to the track groove.

[0013] Furthermore, a gas spring is fixedly connected to the bottom of the slider, and the bottom of the gas spring is fixedly connected to the bottom wall of the track groove.

[0014] Furthermore, a top block is provided above the slide, and the top of the top block is fixedly connected to the mounting bracket.

[0015] In summary, this utility model has at least one of the following beneficial technical effects:

[0016] 1. The bearing edge-rolling cover stamping device, through the set upper die assembly, can make the upper die assembly and the lower die close together. When the upper die assembly and the lower die are closed, the upper die plate and the slide plate are supported by the support force after the slide plate or the support plate abuts against the edge-rolling cover. Then, the support plate is flipped by the angle adjustment unit, so that the support plate provides support for the inner wall of the edge-rolling cover. This can avoid the edge-rolling cover from deforming due to lack of support when it is rolled up, thus effectively ensuring the rolling quality of the edge-rolling cover.

[0017] 2. This bearing rolled edge cover stamping device, through the installation of a gas spring, can buffer and slow down the resetting between the slide table and the upper template when the hydraulic press moves the upper mold assembly back to its original position. At this time, the support plate will abut against the rolled edge of the rolled edge cover because it cannot be fully reset, thereby providing support for the rolled edge cover. The rolled edge cover is then lifted by the support plate and demolded, thus achieving the effect of automatic unloading of the rolled edge cover and greatly improving the production efficiency of the rolled edge cover.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0026] Reference Figures 1-5 The present invention discloses a bearing edge-stamping device, comprising:

[0027] Base 1, with mounting bracket 4 fixedly connected to the top of base 1;

[0028] The lower mold 2 is installed on the top of the base 1, and the top of the lower mold 2 is provided with a placement groove 5 for placing the rolled edge cover;

[0029] The upper mold assembly 3 is located above the base 1 and is used to stamp the edge of the rolled edge cover. The upper mold assembly 3 includes an upper template 31, a slide table 32 and a support plate 33. The top of the upper template 31 is connected to the mounting frame 4 via a hydraulic press 6. A circular hole 7 is opened in the middle of the upper template 31. The slide table 32 is slidably connected in the circular hole 7. Multiple support plates 33 for supporting the inner wall of the rolled edge cover are arranged in a circular array on the slide table 32. An angle adjustment unit 8 is provided between the upper template 31 and the support plate 33. A groove 9 for stamping the rolled edge cover is opened at the bottom of the upper template 31 outside the circular hole 7.

[0030] In this embodiment, observation Figure 1 It can be seen that by setting a base 1, a lower mold 2 is fixedly connected to the top of the base 1, and a placement groove 5 for placing the rolled edge cover is opened on the top of the lower mold 2. Then, a mounting bracket 4 is fixedly connected to the top of the base 1, and an upper mold assembly 3 is set at the bottom of the mounting bracket 4. The edge of the rolled edge cover can be stamped out a second time by the cooperation of the upper mold assembly 3 and the lower mold 2, so as to facilitate the production of the rolled edge cover.

[0031] During the secondary stamping process, the lack of support on the inner wall of the rolled edge cover will cause the edge of the rolled edge cover to deform when it is rolled inward, which will affect the production of the rolled edge cover.

[0032] Therefore, observe Figure 1 and Figure 4 It can be seen that the upper mold assembly 3 includes an upper template 31, a slide table 32 and a support plate 33. The top of the upper template 31 is connected to the mounting frame 4 through a hydraulic press 6. A circular hole 7 is opened in the middle of the upper template 31. The slide table 32 is slidably connected in the circular hole 7. Multiple support plates 33 for supporting the inner wall of the rolled edge cover are arranged in a circular array of the slide table 32. An angle adjustment unit 8 is provided between the upper template 31 and the support plate 33. A groove 9 for stamping the rolled edge cover is opened at the bottom of the upper template 31 outside the circular hole 7.

[0033] At this point, when a secondary stamping of the rolled edge cover is required, the hydraulic press 6 is controlled by the controller to lower the upper template 31, while the upper template 31 is as follows: Figure 2 As the device descends as indicated, the slide 32 located in the circular hole 7 of the upper template 31 will simultaneously move down and insert into the crimped cover. When the bottom of the slide 32 or support plate 33 contacts the crimped cover, the slide 32 will be supported and move upward within the circular hole 7 as the hydraulic press 6 continues to output power. At this time, the angle adjustment unit 8 will push the support plate 33 as shown in the figure. Figure 3 The flipping motion, as shown in the diagram, causes the support plate 33 to contact the inner wall of the rolled edge cover, thereby supporting the rolled edge cover and preventing the groove 9 from squeezing it so that it will not deform when flipping, thus ensuring the flipping effect of the rolled edge cover and guaranteeing the production quality of the rolled edge cover.

[0034] In a further preferred embodiment of this utility model, such as Figure 4 As shown, by providing multiple receiving grooves 10 at the bottom of the slide table 32 to accommodate the support plate 33, the support plate 33 is rotatably connected in the receiving grooves 10. This allows the support plate 33 to be initially retracted into the receiving grooves 10, ensuring that the support plate 33 will not collide with the edge of the rolled edge cover when the slide table 32 is lowered, thus affecting the mold closing of the upper mold assembly 3 and the lower mold 2, thereby ensuring the production efficiency of the rolled edge cover.

[0035] In a further preferred embodiment of this utility model, such as Figure 4 As shown, by making the angle adjustment unit 8 include a toothed plate 81 and a gear 82, and the gear 82 is provided at the connection between the support plate 33 and the slide 32, and the toothed plate 81 that meshes with the gear 82 is fixedly connected to the inner wall of the round hole 7, the support plate 33 can be rotated by the toothed plate 81 carrying the gear 82 when the slide 32 moves relative to the upper template 31, thereby ensuring the support effect of the support plate 33.

[0036] Meanwhile, since gear 82 is connected to support plate 33, gear 82 is a toothless gear, which facilitates the connection between support plate 33 and gear 82.

[0037] In a further preferred embodiment of this utility model, such as Figure 5As shown, by providing a track groove 11 on the outer wall of the slide table 32, and fixing a slider 12 to the inner wall of the round hole 7 at the position corresponding to the track groove 11, the slide table 32 can be made more stable when moving relative to the upper template 31.

[0038] In a further preferred embodiment of this utility model, such as Figure 5 As shown, by fixing a gas spring 13 to the bottom of the slider 12, and fixing the bottom of the gas spring 13 to the bottom wall of the track groove 11, after the crimped cover is stamped, when the hydraulic press 6 resets the upper mold assembly 3, the slide table 32 and the upper template 31 are buffered and the reset is slowed down by the gas spring 13. At this time, the support plate 33 will abut against the crimped edge of the crimped cover because it cannot be completely reset, thereby providing support for the crimped cover, so that the crimped cover is lifted by the support plate 33 and demolded, thereby achieving the effect of automatic unloading of the crimped cover and greatly improving the production efficiency of the crimped cover.

[0039] In a further preferred embodiment of this utility model, such as Figure 2 As shown, by providing a top block 14 above the slide 32, and fixing the top of the top block 14 to the mounting bracket 4, the slide 32 can be moved down by the top block 14 against the top of the slide 32 after the upper mold assembly 3 is fully reset, thereby ensuring that the support plate 33 can be fully reset after the upper mold assembly 3 is reset, and avoiding the support plate 33 from jamming the rolled edge cover after the upper mold assembly 3 is reset, thus affecting the unloading of the rolled edge cover.

[0040] The implementation principle of the above embodiment is as follows: the rolled edge cover is placed in the placement groove 5 of the lower mold 2, and then the hydraulic press 6 is started by the controller to lower the upper mold assembly 3. When the upper mold assembly 3 moves down, the slide table 32 or the support plate 33 first comes into contact with the rolled edge cover. As the hydraulic press 6 continues to run, the upper template 31 will slide relative to the slide table 32. At this time, under the action of the angle adjustment unit 8, the support plate 33 will flip to provide support to the inner wall of the rolled edge cover, so that the rolled edge cover will not deform when it is stamped and turned, thereby ensuring the production quality of the rolled edge cover.

[0041] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
