Description

Technical Field

[0001] This utility model belongs to the technical field of tapered roller bearings, and more specifically, it relates to a stamping equipment for cages of medium and large-sized tapered roller bearings. Background Technology

[0002] In the assembly process of cages and inner rings of medium and large-sized tapered roller bearings, stamping assembly equipment can precisely align the cage window with the positions of the rollers and inner ring through mechanical structure and pressure control, ensuring consistent assembly accuracy for each bearing and avoiding problems such as roller jamming and poor rotation caused by rough manual operation. This improves the overall stability and reliability of the bearing. Currently, existing stamping equipment for cages of medium and large-sized tapered roller bearings typically consists of a main body, a hydraulic cylinder, a sliding component slidably connected to the main body, and a pressing die located inside the sliding component for placing and fixing the cage and inner ring.

[0003] Based on the above, after the stamping of medium and large-sized tapered roller bearing cages is completed, the height of the bearing cage protruding from the mold is low, the handling space is relatively small, and the weight of the cage itself is large, making it difficult for workers to hold the workpiece stably. The workpiece is very easy to fall due to the inconvenience of handling. At the same time, the workpiece is tightly adhered to the inside of the mold after stamping, making it more difficult to handle. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a stamping equipment for medium and large-sized tapered roller bearing cages. This solves the problem that existing stamping equipment for medium and large-sized tapered roller bearing cages, after stamping, suffers from issues such as the low height of the bearing cage protruding from the mold, limited handling space, and significant weight, making it difficult for workers to steadily grasp the workpiece and easily causing it to fall due to handling difficulties. Furthermore, the workpiece is tightly adhered to the inside of the mold after stamping, making handling even more strenuous.

[0005] The purpose and effectiveness of this utility model's large-size tapered roller bearing cage stamping equipment are achieved through the following specific technical means:

[0006] A stamping machine for medium and large-sized tapered roller bearing cages includes a stamping machine body, a hydraulic cylinder, a sliding component, a pressing die, fixed blocks, fixed racks, a limit box, a lifting plate, an automatic lifting assembly, and a limit assembly. The hydraulic cylinder is fixedly connected to the top of the stamping machine body. The sliding component is slidably connected inside the stamping machine body. The pressing die is fixedly connected inside the sliding component. Two fixed blocks are provided, separately fixedly connected to the stamping machine body. Two fixed racks are provided, respectively fixedly connected to two fixed blocks. The limit box is fixedly connected to the stamping machine body. The lifting plate is located inside the pressing die. Two sets of automatic lifting assemblies are provided, separately located on the left and right sides of the stamping machine body. The limit assembly is located inside the limit box.

[0007] Furthermore, the automatic lifting assembly includes: a transmission box and a first transmission gear; the transmission box is fixedly connected to the outside of the press body; the first transmission gear is rotatably connected inside the transmission box, and the first transmission gear meshes with a fixed rack.

[0008] Furthermore, the automatic lifting assembly also includes: a transmission ratchet, a first transmission shaft, and a transmission pawl; the transmission ratchet is coaxially and fixedly connected to the inner side of the first transmission gear; the first transmission shaft is rotatably connected to the inside of the transmission box; the transmission pawl is coaxially and fixedly connected to the outer end of the first transmission shaft, and the transmission pawl meshes with the transmission ratchet.

[0009] Furthermore, the automatic lifting assembly also includes: a second transmission gear, a sliding plate, and a second transmission rack; the second transmission gear is coaxially and fixedly connected to the inner end of the first transmission shaft; the sliding plate has an "L" shaped structure, the sliding plate is slidably connected inside the sliding member, and the top of the sliding plate is fixedly connected to the bottom of the lifting plate; the second transmission rack is fixedly connected above the outer end of the sliding plate, and the second transmission rack meshes with the second transmission gear.

[0010] Furthermore, the limiting component includes a slider and an operating handle; the slider is slidably connected inside the limiting box; and the operating handle is fixedly connected to the slider.

[0011] Furthermore, the limiting assembly also includes a limiting plate and a limiting spring; the limiting plate is fixedly connected to the right side of the slider; the right end of the limiting spring is fixedly connected to the left side of the slider, and the left end of the limiting spring is fixedly connected to the inside of the limiting box.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] First, by utilizing the transmission structure in the automatic lifting assembly during the sliding component dragging process, the sliding plate and lifting plate move upward, automatically lifting the stamped cage and inner ring. The lifting action is synchronized with the manual dragging process of the sliding component, without the need for additional power, expanding the range that can be manually handled, reducing the risk of falls, and effectively ensuring the personal safety of workers.

[0014] Secondly, by using the limit plate to contact the transmission box to prevent excessive dragging of the sliding parts, the lifting distance is ensured to be precise and controllable, providing sufficient operating space for workpiece handling and preventing the lifting plate from accidentally falling back due to excessive dragging of the sliding parts. When resetting, the limit is released by operating the handle, and the lifting plate automatically falls back under its own weight. The station can be reset without complicated debugging, which not only ensures the stability of new workpiece placement but also improves the efficiency of cyclic operation.

[0015] In the process of dragging the sliding parts, this utility model utilizes the transmission structure of the automatic lifting component to automatically lift the stamped cage and inner ring. Its action is synchronized with the manual dragging action, which can expand the handling operation range without additional power and effectively reduce the risk of workpiece falling. At the same time, the limiting plate prevents the sliding parts from being dragged excessively, ensuring that the lifting distance is accurate and controllable. Overall, this design significantly reduces the intensity of manual operation, reduces safety hazards, and improves the safety and convenience of the assembly process. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example 1:

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a stamping equipment for medium and large-sized tapered roller bearing cages, including a stamping machine body 1, a hydraulic cylinder 2, a sliding component 3, a pressing die 301, a fixing block 5, a fixing rack 501, a limit box 6, a lifting plate 902, and an automatic lifting assembly; the hydraulic cylinder 2 is fixedly connected to the top of the stamping machine body 1; the sliding component 3 is slidably connected inside the stamping machine body 1; the pressing die 301 is fixedly connected inside the sliding component 3; two fixing blocks 5 are provided, and the two fixing blocks 5 are separately fixedly connected to the stamping machine body 1; two fixing racks 501 are provided, and the two fixing racks 501 are respectively fixedly connected to the two fixing blocks 5; the limit box 6 is fixedly connected to the stamping machine body 1; the lifting plate 902 is set inside the pressing die 301; two sets of automatic lifting assemblies are provided, and the two sets of automatic lifting assemblies are separately set on the left and right sides of the stamping machine body 1.

[0028] The automatic lifting assembly includes a transmission box 4 and a first transmission gear 7. The transmission box 4 is fixedly connected to the outside of the main body 1 of the press. The first transmission gear 7 is rotatably connected inside the transmission box 4 and meshes with the fixed rack 501.

[0029] The automatic lifting assembly also includes: a transmission ratchet 701, a first transmission shaft 8, and a transmission pawl 801; the transmission ratchet 701 is coaxially fixedly connected to the inner side of the first transmission gear 7; the first transmission shaft 8 is rotatably connected to the inside of the transmission box 4; the transmission pawl 801 is coaxially fixedly connected to the outer end of the first transmission shaft 8, and the transmission pawl 801 meshes with the transmission ratchet 701.

[0030] The automatic lifting assembly also includes: a second transmission gear 802, a sliding plate 9, and a second transmission rack 901; the second transmission gear 802 is coaxially fixedly connected to the inner end of the first transmission shaft 8; the sliding plate 9 has an "L" shaped structure, is slidably connected inside the sliding member 3, and the top of the sliding plate 9 is fixedly connected to the bottom of the lifting plate 902; the second transmission rack 901 is fixedly connected to the upper part of the outer end of the sliding plate 9, and the second transmission rack 901 meshes with the second transmission gear 802.

[0031] The specific usage and function of this embodiment are as follows: During use, the cage and inner ring of the tapered roller bearing are placed inside the pressing mold 301 for stamping. After stamping, the sliding member 3 is dragged forward to pull the cage and inner ring out from under the pressure plate of the hydraulic cylinder 2. During the dragging process, when the first transmission gear 7 meshes with the fixed rack 501, the gear and rack transmission mechanism formed by the two will drive the first transmission gear 7 to rotate. The first transmission gear 7 drives the first transmission shaft 8 to rotate in one direction through the ratchet and pawl transmission mechanism formed by the ratchet 701 and the pawl 801. The first transmission shaft 8 drives the sliding plate 9 to move upward through the gear and rack transmission mechanism formed by the second transmission rack 901 and the second transmission gear 802. The sliding plate 9 drives the lifting plate 902 to move upward synchronously, thereby lifting the tapered roller bearing cage and inner ring that have been stamped inside the pressing mold 301, making it convenient for workers to handle.

[0032] Example 2:

[0033] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 It also includes a limit component, which is located inside the limit box 6.

[0034] The limiting component includes a slider 10 and an operating handle 1001; the slider 10 is slidably connected inside the limiting box 6; and the operating handle 1001 is fixedly connected to the slider 10.

[0035] The limiting assembly also includes a limiting plate 1002 and a limiting spring 1003; the limiting plate 1002 is fixedly connected to the right side of the slider 10; the right end of the limiting spring 1003 is fixedly connected to the left side of the slider 10, and the left end of the limiting spring 1003 is fixedly connected to the inside of the limiting box 6.

[0036] The specific usage and function of this embodiment are as follows: During the process of dragging the slider 3 forward, when the sliding plate 9 drives the tapered roller bearing cage and inner ring to move upward to the top, the transmission box 4 and the limiting plate 1002 come into contact. This prevents the slider 3 from being dragged forward too much, which would cause the first transmission gear 7 to disengage from the fixed rack 501 and cause the lifting plate 902 to fall downward. After the stamped tapered roller bearing cage and inner ring are moved to another position by the workers, the operating handle 1001 is moved to the left, causing the slider 10 and the limiting plate 1002 to move to the left synchronously. The limiting plate 1002 releases its obstruction to the transmission box 4. At this time, the slider 3 is dragged forward again. Under the weight of the lifting plate 902 and the sliding plate 9, the lifting plate 902 and the sliding plate 9 fall back to their initial positions. Then, a new tapered roller bearing cage and inner ring can be placed in the pressing mold 301. After placement, move the operating handle 1001 to the left again, and then push the sliding member 3 backward to push the new tapered roller bearing cage and inner ring under the pressure plate of the hydraulic cylinder 2 for stamping. When the transmission box 4 moves behind the limit plate 1002, release the operating handle 1001. Under the rebound action of the limit spring 1003, the limit plate 1002 returns to its original position for easy use next time. Under the action of the ratchet and pawl transmission mechanism composed of the transmission ratchet 701 and the transmission pawl 801, the first transmission shaft 8 will not rotate during the backward movement of the sliding member 3, so that the lifting plate 902 will not be displaced, ensuring the stable placement of the newly placed tapered roller bearing cage and inner ring, and ensuring the subsequent stamping effect.
