Description

Technical Field

[0001] This utility model relates to the field of tapered bearing processing technology, specifically to a multi-station forming mold that facilitates automatic unloading from one side. Background Technology

[0002] In the manufacturing process of tapered bearings, multi-station forming dies can complete multiple processing steps such as upsetting, extrusion, nesting, and flattening within a single die, thereby improving production efficiency and product quality. However, in traditional multi-station forming dies, after the nesting punch completes the nesting, the material segment tends to adhere to the punch, requiring manual or other auxiliary tools for unloading. This not only increases the labor intensity of operators but also reduces production efficiency. Furthermore, separate unloading can cause the material segment to fall into the lower nesting die holder, making it difficult to grasp and transfer using a gripper. Due to the unreasonable unloading position, existing dies often require manual intervention or additional mechanical devices for material segment transfer, significantly reducing automation and production efficiency. Utility Model Content

[0003] This utility model provides a multi-station forming mold that facilitates automatic unloading from one side, thereby solving the technical problem in the prior art where it is inconvenient to complete the nesting process and connect it with the next process in multi-station forming molds.

[0004] To solve the above problems, the present invention provides a multi-station forming mold that facilitates automatic unloading from one side, using the following technical solution:

[0005] It includes a fixed lower template and a stamping upper template. Between the fixed lower template and the stamping upper template, there are multiple workstations for completing different processes. Among these multiple workstations, there is a nesting processing workstation. The nesting processing workstation includes an upper nesting die base located on the lower surface of the stamping upper template and a lower nesting die base located on the upper surface of the fixed lower template. The upper nesting die base includes a nesting punch. An unloading plate is provided above the lower nesting die base with a gap. An unloading die sleeve is provided on the unloading plate. The nesting punch reciprocates through the unloading die sleeve to complete the nesting or unloading of the material segment.

[0006] A material carrier plate is provided on one side of the lower die holder. The material carrier plate is located between the unloading plate and the lower die holder. A power component is provided on one side of the material carrier plate to drive the material carrier plate to move laterally back and forth.

[0007] Furthermore, the inner wall of the end of the unloading mold sleeve opposite to the upper mold base is a flared end in the shape of a trumpet, and the inner wall of the end of the unloading mold sleeve opposite to the lower mold base is a guide end in the shape of a straight wall.

[0008] Furthermore, when the sleeve punch passes through the unloading die, the outer wall of the sleeve punch slides in contact with the inner wall of the guide end, and the diameter of the inner wall of the guide end is smaller than the diameter of the outer wall of the material section.

[0009] Furthermore, the outer wall of the unloading mold sleeve is a straight wall type, and the unloading plate is provided with a through hole that is interference fit with the unloading mold sleeve;

[0010] The outer wall of the unloading mold sleeve, which is close to the lower mold base, is provided with a limiting ring, and one end of the through hole is provided with a limiting step that cooperates with the limiting ring.

[0011] Furthermore, a support column for supporting the unloading plate is provided on the side of the lower die holder that is close to the power component.

[0012] The lower die holder is provided with a gripper on the side away from the power component for gripping the material segment.

[0013] Furthermore, the end of the bushing punch that is close to the upper bushing die base is a trumpet-shaped connecting end, and a connecting sleeve is provided on the connecting end. The upper bushing die base also includes a connecting seat, and the connecting sleeve is detachably fixed to the connecting seat by a connecting nut. The end of the connecting nut away from the connecting seat is provided with a groove that mates with the connecting sleeve.

[0014] Furthermore, the lower die holder includes a base, the base is provided with an extrusion cavity, the extrusion cavity is provided with an annular bottom die, the annular bottom die is provided with an extrusion die, the annular bottom die and the extrusion die are pressed into the extrusion cavity by a clamping nut, the upper outer wall of the extrusion die is an inclined guide surface inside the box, and the upper end of the inner wall of the clamping nut is a clamping inclined surface that cooperates with the guide inclined surface.

[0015] The beneficial effects of the multi-station forming mold that facilitates automatic unloading from one side provided by this utility model are:

[0016] 1. In this invention, a power component (such as a cylinder) drives the material carrier plate to move laterally and reciprocally. After the material punch moves upward with the material segment and exits the lower material carrier die, the material carrier plate moves forward to below the material segment, so that the material segment rests on the material carrier plate. Then, the gripper picks up the material segment from the material carrier plate and moves it to the next adjacent workstation for subsequent processing. The entire process is automated, reducing manual operation and improving production efficiency and product quality consistency.

[0017] 2. In this utility model, the structure is reasonable and the operation is reliable. The flared end of the unloading die sleeve facilitates the entry of the nesting punch, and the guide end is a straight-walled type. When the nesting punch passes through, the outer wall slides in contact with the inner wall of the guide end, and the diameter of the inner wall of the guide end is smaller than the diameter of the outer wall of the material section. This design ensures the stability of the nesting punch during movement, reduces deviations during the nesting process, and improves the accuracy of nesting. The unloading die sleeve and the unloading plate are connected by an interference fit through hole and a limiting ring and a limiting step, ensuring the stable installation of the unloading die sleeve and preventing it from moving or loosening during operation, thus ensuring the smooth progress of the nesting and unloading processes.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0029] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0030] An embodiment of a multi-station forming mold that facilitates automatic unloading from one side provided by this utility model:

[0031] like Figures 1 to 6 As shown,

[0032] It includes a fixed lower template 1 and a stamping upper template 2. There are multiple workstations between the fixed lower template 1 and the stamping upper template 2 for completing different processes. Among the multiple workstations, there is a nesting processing workstation. The nesting processing workstation includes an upper nesting die base 3 located on the lower surface of the stamping upper template 2 and a lower nesting die base 4 located on the upper surface of the fixed lower template 1. The upper nesting die base 3 includes a nesting punch 31.

[0033] Among them, the end of the nesting punch 31 that is close to the upper nesting die base 3 is a flared connecting end 311. The connecting end 311 is covered with a connecting sleeve 312. The upper nesting die base 3 also includes a connecting seat 32. The connecting sleeve 312 is detachably fixed to the connecting seat 32 by a connecting nut 33. The end of the connecting nut 33 away from the connecting seat 32 is provided with a groove 331 that mates with the connecting sleeve 312.

[0034] The above structure enables convenient disassembly, installation, and replacement of the sleeve punch 31. When the sleeve punch 31 is worn or needs to be replaced with a different specification, it can be completed simply by operating the connecting nut 33, which improves the convenience of equipment maintenance.

[0035] The lower die holder 4 includes a base 41, an extrusion chamber 411 inside the base 41, an annular bottom die 42 inside the extrusion chamber 411, and an extrusion die 43 on the annular bottom die 42. The annular bottom die 42 and the extrusion die 43 are pressed into the extrusion chamber 411 by a clamping nut 44. The upper outer wall of the extrusion die 43 is an inclined guide surface inside the box, and the upper end of the inner wall of the clamping nut 44 is a clamping inclined surface that cooperates with the guide inclined surface.

[0036] The above structure ensures the stable installation of the annular bottom mold 42 and the extrusion mold 43, guaranteeing stability and machining accuracy during the nesting process. Furthermore, it allows for easy disassembly, improving the convenience of equipment maintenance.

[0037] In this embodiment, a material unloading plate 5 is provided above the lower material unloading mold base 4 with an opening, and a material unloading mold sleeve 51 is provided on the material unloading plate 5. The material unloading punch 31 reciprocates through the material unloading mold sleeve 51 to complete the material unloading or unloading of the material segment.

[0038] Among them, the inner wall of the unloading mold sleeve 51 opposite to the upper mold base 3 is a flared end 511 in the shape of a horn, and the inner wall of the unloading mold sleeve 51 opposite to the lower mold base 4 is a guide end 512 in the shape of a straight wall.

[0039] The flared end 511, shaped like a trumpet, facilitates the entry of the sleeve punch 31. When the sleeve punch 31 passes through the unloading die sleeve 51, the outer wall of the sleeve punch 31 slides in contact with the inner wall of the guide end 512. The inner diameter of the guide end 512 is smaller than the outer diameter of the material section. This ensures the stability of the sleeve punch 31 during movement.

[0040] The outer wall of the unloading mold sleeve 51 is a straight wall type, and the unloading plate 5 is provided with a through hole 50 that is interference fit with the unloading mold sleeve 51.

[0041] The outer wall of the unloading mold sleeve 51, which is close to the lower mold base 4, is provided with a limiting ring 513, and one end of the through hole 50 is provided with a limiting step 501 that cooperates with the limiting ring 513.

[0042] The unloading plate 5 is provided with a through hole 50 that is interference-fitted with the unloading mold sleeve 51, ensuring a tight connection between the unloading mold sleeve 51 and the unloading plate 5. A limiting ring 513 is provided on the outer wall of the end of the unloading mold sleeve 51 that is close to the lower sleeve mold base 4, and a limiting step 501 that cooperates with the limiting ring 513 is provided at one end of the through hole 50, further restricting the installation position of the unloading mold sleeve 51.

[0043] Specifically, after the blanking punch 31 completes the blanking process of the material segment by pressing downwards, the blanking punch 31 will reset and move upwards. During the upward movement, the material segment will move upwards along with it. The blanking punch 31 can pass through the unloading die sleeve 51, but the material segment cannot pass through. At this time, the unloading die sleeve 51 will assist in removing the material segment from the blanking punch 31.

[0044] In this embodiment, a material carrier plate 6 is provided on one side of the lower die holder 4. The material carrier plate 6 is located between the unloading plate 5 and the lower die holder 4. A power component 7 is provided on one side of the material carrier plate 6 to drive the material carrier plate 6 to move laterally back and forth. The power component can be a cylinder, or in other embodiments, it can be an electric telescopic rod.

[0045] The side of the fixed lower template 1 is provided with a vertical plate for supporting the power component 7.

[0046] In practical use, when the sleeve punch 31 moves upward with the material segment and moves out of the lower sleeve die base 4, the loading plate 6 extends forward through the action of the cylinder and is located below the material segment, so that the material segment unloaded by the unloading die 51 is placed on the loading plate 6.

[0047] The lower die holder 4 has a gripper on the other side for gripping material segments, which is used to grip the material segments and place them on other workstations.

[0048] The material segment is picked up from the loading plate 6 by the gripper and transferred to the next adjacent station for further processing.

[0049] The lower die holder 4 has a support column 52 on the side closest to the power component 7 to support the unloading plate 5. The gripper for gripping the material section is located on the side of the lower die holder 4 away from the power component 7.

[0050] Among them, the support column 52 is located on the side away from the gripper to avoid interfering with the movement of the gripper.

[0051] In this embodiment, the multi-station forming mold, which facilitates automatic unloading from one side, operates as follows: The upper stamping platen 2 moves downwards, driving the insert punch 31 downwards through the unloading die sleeve 51, stamping the blank on the lower insert die base 4 and completing the inserting process. As the upper stamping platen 2 moves upwards, the material segment moves upwards with the insert punch 31. When passing through the unloading die sleeve 51, the guide end 512 blocks the material segment, causing it to fall off. The power component 7, i.e., the cylinder, pushes the carrier plate 6 forward, causing the material segment to fall onto the carrier plate 6. Finally, the gripper picks up the material segment from the carrier plate 6 and moves it to the next adjacent station for subsequent processing.

[0052] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0053] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
