[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-5As shown, a multi-station punching equipment for rubber parts includes a support frame 1 with a punching bracket 3 mounted on top. One end of the support frame 1 is slidably connected to a plurality of punching templates 2 and an arc-shaped guard plate 5. One end of the punching template 2 is rotatably connected to a drive chain 16. One end of the drive chain 16 is drivenly connected to a sprocket 14. An internal support frame 21 is fixedly connected to one side of the support frame 1. One end of the sprocket 14 is fixedly connected to a drive assembly.

[0031] The drive assembly includes a drive motor 18 and a drive shaft 19. Multiple sprockets 14 are fixedly connected to the drive shaft 19. One end of the drive shaft 19 is fixedly connected to the power output end of the drive motor 18, and the other end of the drive motor 18 is fixedly connected to the support frame 1.

[0032] When the device is working, the operator places a large rubber sheet on one side of the upper punching template 2. The drive motor 18 drives the sprocket 14 to rotate through the drive shaft 19, which in turn drives the drive chain 16 to rotate. At this time, the multiple punching templates 2 above can rotate with the drive chain 16. When the punching template 2 moves to the bottom of the punching bracket 3, the drive motor 18 stops moving to punch. After punching is completed, the drive motor 18 continues to drive the punching template 2 to rotate. When it moves forward and flips downward, the arc-shaped guard plate 5 can prevent the punched waste from falling. At this time, the punched workpiece falls. When it continues to rotate to the area without the arc-shaped guard plate 5, the punched waste falls automatically, realizing the functions of automatic classification and automatic removal of punched waste.

[0033] The internal support frame 21 can support the punching template 2 from below during punching to prevent it from collapsing.

[0034] In this embodiment, a hydraulic rod 4 is fixedly connected to one end of the punching bracket 3, and a punching plate 8 is fixedly connected to the movable end of the hydraulic rod 4. The punching plate 8 is slidably connected to the punching bracket 3 on one side. A plurality of punching cutters 9 are fixedly connected to one end of the punching plate 8. A punching groove 13 is opened at one end of the punching template 2. The arc-shaped guard plate 5 is installed between two punching grooves 13.

[0035] When the hydraulic rod 4 extends, it can drive the punching plate 8 to move downward, thereby driving multiple punching tools 9 to insert into the corresponding punching grooves 13 on the punching template 2 for cutting. The punching tools 9 and the punching grooves 13 can change shape as needed.

[0036] In this embodiment, one end of the first sprocket 14 on one side is fixedly connected to the second sprocket 15. Multiple second sprockets 15 are connected by a synchronous chain 17. The second sprockets 15, together with the synchronous chain 17, can make the first sprockets 14 on both sides rotate simultaneously, making the movement of the punching template 2 more stable.

[0037] In this embodiment, recycling bin 6 and recycling bin 7 are fixedly connected below the support frame 1. Recycling bin 6 is located on the lower side of the arc-shaped guard plate 5, and recycling bin 7 is located on the side without the arc-shaped guard plate 5 and is used to store the waste material after punching.

[0038] In this embodiment: When the device is working, the operator places a large piece of rubber on one side of the upper punching template 2. The drive motor 18 drives the sprocket 14 to rotate through the drive shaft 19, which in turn drives the drive chain 16 to rotate. At this time, the multiple upper punching templates 2 can rotate with the drive chain 16. When the punching template 2 moves to the bottom of the punching bracket 3, the drive motor 18 stops moving to punch. After punching is completed, the drive motor 18 continues to drive the punching template 2 to rotate. When it moves forward and flips downward, the arc-shaped guard plate 5 can prevent the punched waste from falling. At this time, the punched workpiece falls. When it continues to rotate to the area without the arc-shaped guard plate 5, the punched waste falls automatically, realizing the functions of automatic classification and automatic removal of punched waste.

[0039] The internal support frame 21 can support the punching template 2 from below during punching to prevent it from collapsing;

[0040] When the hydraulic rod 4 extends, it can drive the punching plate 8 to move downward, thereby driving multiple punching tools 9 to insert into the corresponding punching grooves 13 on the punching template 2 for cutting. The punching tools 9 and the punching grooves 13 can change their shapes as needed.

[0041] The second sprocket 15, in conjunction with the synchronous chain 17, allows the first sprockets 14 on both sides to rotate simultaneously, making the movement of the punching template 2 more stable;

[0042] Recycling bin 1 (6) is located under the curved guard plate 5, and recycling bin 2 (7) is located on the side without the curved guard plate 5 and is used to store the waste material after punching.

[0043] Example 2:

[0044] A multi-station punching and cutting device for rubber parts, this embodiment is based on embodiment 1 with the following improvements, such as... Figure 1-5 As shown,

[0045] In this embodiment, one end of the punching bracket 3 is fixedly connected to a spray pipe 20. The spray pipe 20 can spray a release agent onto the surface of the rubber sheet to be punched below during punching to prevent the rubber sheet from getting stuck in the punching tool 9.

[0046] In this embodiment, a plurality of limiting pressure plates 12 are slidably connected to one end of the punching plate 8, and a pressing plate 10 is fixedly connected to one end of the limiting pressure plate 12. A spring 11 is fixedly connected to one end of the pressing plate 10 and the pressing plate 10. The limiting pressure plate 12 can press the workpiece before the punching tool 9 contacts the workpiece, so that the workpiece remains stable during punching and deformation is reduced. The limiting pressure plate 12 will slide upward during punching and will not affect normal punching.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model.
