[0002] like Figure 7 The arc-shaped sealing strip shown in the figure involves a cutting process during its processing. The existing cutting method mainly involves punching the sealing strip with a vibrating knife or cutting the sealing strip with a laser cutting device.

[0003] However, the vibration knife punching method is affected by the thickness of the sealing strip. When the thickness of the rubber sealing strip is thicker, the vibration knife punching method cannot achieve the ideal cutting effect. Laser cutting is a processing method that focuses a high-power laser beam and irradiates it on the workpiece, causing the irradiated position to quickly melt, vaporize, burn or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the light beam to blow away the molten material to cut the workpiece. During the laser cutting process, the cross-section of the sealing strip is prone to carbonization, making it impossible to connect the sealing strip. In addition, the efficiency of laser cutting is low, and the energy consumption and cost are high. Summary of the invention

[0033] Rack 1;

[0034] The punching assembly 2 includes a punching die set 21, a first driving source 22 and a cutter 23. The punching die set 21 includes an upper die 211 and a lower die 212. The lower die 212 is arranged on the frame 1. The upper die 211 is connected to the lower die 212, and a passage 24 is arranged between the upper die 211 and the lower die 212. The first driving source 22 is arranged on the frame 1. The output end of the first driving source 22 is connected to the cutter 23. The first driving source 22 drives the cutter 23 to sequentially penetrate the upper die 211, the passage 24 and the lower die 212.

[0035] The transfer assembly 3 includes a slide 31 and a second driving source 32. The slide 31 is slidably disposed on the frame 1 along the axial direction of the passage 24. The second driving source 32 is connected to the frame 1 and drives the slide 31 to slide.

[0036] The lifting assembly 4 includes a third driving source 41 . The third driving source 41 is connected to the frame 1 at a side of the passage 24 away from the slide 31 , and an output end of the third driving source 41 coaxially extends toward the passage 24 .

[0037] Specifically, the frame 1 includes a bottom plate 11 and a bracket 12, the bottom plate 11 is horizontally arranged, and the bracket 12 includes two vertical poles connected to the bottom plate 11 and a horizontal plate connected between the two vertical poles;

[0038] The punching die set 21 is arranged below the horizontal plate, wherein the lower die 212 of the punching die set 21 is connected to the bottom plate 11, the upper die 211 is arranged on the top of the lower die 212, and a groove is arranged on the bottom surface of the upper die 211, so that a horizontal passage is formed between the upper die 211 and the lower die 212 after they are connected together; the first driving source 22 is vertically connected to the horizontal plate, the output end of the first driving source 22 is vertically downward and connected to the cutter 23, and at the same time, the upper die 211 and the lower die 212 are coaxially provided with a through slot 213 for the cutter 23 to pass through, and the position of the through slot 213 corresponds to the position of the passage 24, and the first driving source 22 can drive the cutter 23 to pass through the upper die 211, the passage 24 and the lower die 212 in sequence to cut the material;

[0039] The transfer assembly 3 is arranged at one side of the punching die set 21, and the transfer assembly 3 includes a slide 31 and a second driving source 32. The slide 31 is connected to the bottom plate 11 by sliding along the axial direction of the passage 24 through a slide rail and a slider structure. A receiving groove for placing materials coaxial with the passage 24 is arranged on the slide 31. The second driving source 32 is horizontally connected to the bottom plate 11 parallel to the sliding direction of the slide 31, and the output end of the second driving source 32 is connected to the slide 31. The second driving source 32 can be a cylinder. When the output end of the second driving source 32 is extended or contracted, the slide 31 can be driven to move toward or away from the punching die set 21.

[0040] The lifting assembly 4 is arranged on the other side of the punching module 21, and the lifting assembly 4 includes a third driving source 41 horizontally connected to the base plate 11, and the output end of the third driving source 41 is connected to a push rod coaxially extending toward the passage 24. When the output end of the third driving source 41 is extended, the push rod can extend into the passage 24.

[0041] Working process: place the sealing strip to be cut on the slide 31, control the second driving source 32 to drive the slide 31 to move toward the punching die set 21, the slide 31 drives the sealing strip thereon to move to the passage 24 between the upper die 211 and the lower die 212, after the slide 31 is in place, control the second driving source 32 to drive the cutter 23 to cut the sealing strip located below it, after the cutting is completed, control the first driving source 22 and the second driving source 32 to reset, the sealing strip with a part of the end cut off moves with the slide 31 to the outside of the passage 24, and then control the third driving source 41 to drive the push rod to extend into the passage 24 to push the end of the cut sealing strip out of the passage 24 and pick it up manually or by grabbing equipment, and the punching work is completed.

[0042] The sealing strip punching device of the present invention adopts a physical punching method and can automatically punch the sealing strip. The punching efficiency is fast and the precision is high. The end face of the sealing strip is not damaged and the connection angle is not affected. The structure of the whole punching device is simple and the installation and maintenance are convenient, so it is suitable for practical use.

[0043] Reference Figure 2 As shown, further, a plurality of guide rods 25 are vertically arranged on the upper mold 211, a knife holder 221 is connected to the output end of the first driving source 22, a cutter 23 is arranged on the knife holder 221, and a plurality of through holes matching the guide rods 25 are arranged on the knife holder 221, the knife holder 221 is slidably connected to the guide rods 25 through the through holes, and an elastic member 26 is sleeved on each guide rod 25 located between the knife holder 221 and the upper mold 211. Specifically, a plurality of vertical guide rods 25 are symmetrically arranged on the top of the upper mold 211, a plurality of through holes matching the guide rods 25 are arranged on the knife holder 221, the knife holder 221 is slidably connected to the guide rods 25 through the through holes, and a spring located between the upper mold 211 and the knife holder 221 is sleeved on the guide rods 25.

[0044] Reference Figure 3 and Figure 4 As shown, further, a through slot 213 matching the shape of the cross section of the cutter 23 is coaxially arranged on the upper die 211 and the lower die 212. It can be imagined that the through slot 213 matching the cross section of the cutter 23 can guide and limit the cutter 23, ensure the stability of the cutter 23 during the punching process, and ensure the punching accuracy and the final quality of the product.

[0045] Furthermore, the free end of the cutter 23 is in an arc shape that matches the shape of the sealing strip. Specifically, the free end of the cutter 23 (i.e., its punching end) is in a concave arc shape, which can fit closely with the arc surface of the sealing strip during cutting, thereby increasing the contact area and the uniformity of the force, and further improving the punching accuracy.

[0046] Further, the frame 1 is provided with a slide rail parallel to the passage 24, the slide table 31 is slidably connected to the slide rail through a slider, the first driving source 22 is connected to the frame 1 parallel to the slide rail, and the slide table 31 is connected to the output end of the first driving source 22. Specifically, the slide table 31 is provided with a receiving groove coaxial with the passage 24 for receiving and fixing the sealing strip.

[0047] Reference Figure 5 and Figure 6As shown, further, a connection limiter 27 is provided on the lower die 212, the limiter 27 is located on a side close to the slide 31, and a limiter through hole 271 coaxial with the passage 24 is provided on the limiter 27, and the shape of the limiter through hole 271 corresponds to the shape of the sealing strip. It can be imagined that the limiter 27 can limit the position of the sealing strip, ensure the stability of the sealing strip during the cutting process, and further ensure the dimensional accuracy during punching. More preferably, a slide groove can be provided on the top surface of the lower die 212, and the slide groove can guide and limit the sealing strip in the process of the sealing strip entering or exiting the passage 24, and can also guide and limit the cut end in the process of pushing it out of the passage 24.

[0048] Furthermore, the output end of the third driving source 41 is coaxially connected with a push rod. Specifically, in the initial state, when the output end of the third driving source 41 is in a retracted state, the push rod is located outside the passage 24; when the output end of the third driving source 41 is extended, the push rod is driven to extend into the passage 24 and push the end (waste material) punched off from the material to the outside of the passage 24. It should be noted that the position of the push rod needs to avoid the support member in the passage 24 to avoid interference between the push rod and the support member 28 during the pushing process, so as to ensure safe and smooth production.

[0049] Reference Figure 3 As shown, further, a support member 28 matching the shape of the sealing strip is provided in the passage 24. Specifically, when the end of the sealing strip to be cut is moved into the passage 24 by the transfer assembly 3, the end of the sealing strip will be inserted into the support member, and the shape of the support member matches the shape of the inner hole of the sealing strip, which can support the sealing strip to avoid excessive compression deformation of the sealing strip when the cutter cuts the sealing strip, thereby affecting the punching accuracy and ensuring the final quality of the sealing strip.

[0050] Further, the first driving source 22 , the second driving source 32 , and the third driving source 41 may all be cylinders, but are not limited to cylinders.

[0051] Embodiment 2

[0053] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
