Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0019] Reference Figure 1 , 2As shown, the automotive sealing strip punching device of this utility model includes: a frame 901 on which a sealing strip is provided; a sealing strip guiding mechanism 902 mounted on the frame 901, wherein the sealing strip guiding mechanism 902 is provided with a sealing strip and is used to support and guide the punched sealing strip; a clamping mechanism 903 disposed on the frame 901, wherein the clamping mechanism 903 is used to clamp the sealing strip from both sides; and a punching cylinder 904 mounted on the frame 901, wherein the output end of the punching cylinder 904 is connected to a punching blade 905, and the punching cylinder 904 drives the punching blade 905 to punch the sealing strip on the frame 901.

[0020] Reference Figure 3 , 4 As shown, the sealing strip guiding mechanism 902 includes a guide cylinder 906, a connecting plate 907, an upper guide plate 908, and a lower guide plate 909. The guide cylinder 906 is fixedly mounted on the frame 901. The lower guide plate 909 is connected to the output end of the guide cylinder 906 through the connecting plate 907. The upper guide plate 908 is mounted on the lower guide plate 909. The upper guide plate 908 and the lower guide plate 909 are arranged vertically opposite each other, and the opposing surfaces of the upper guide plate 908 and the lower guide plate 909 form a sealing strip conformal cavity. The sealing strip passes through the sealing strip conformal cavity. The surfaces of the upper guide plate 908 and the lower guide plate 909 opposite each other are configured as groove-shaped structures that conform to the upper end surface of the sealing strip. The surfaces of the lower guide plate 909 and the upper guide plate 908 opposite each other are configured as groove-shaped structures that conform to the lower end surface of the sealing strip. In this way, the grooves of the upper guide plate 908 and the lower guide plate 909 fit together to form a sealing strip-shaped cavity for the sealing strip to pass through. After the sealing strip is punched, the lower guide plate 909 receives and guides the cut sealing strip.

[0021] In the above structure, the structure supporting the sliding of the lower guide plate 909 is as follows: a guide rail bracket 910 is provided on the frame 901, and a punching guide rail 911 is provided on the guide rail bracket 910. A punching slider 912 is connected to the lower guide plate 909, and the punching slider 912 is disposed on the punching guide rail 911 and can move along the punching guide rail 911. The setting direction of the punching guide rail 911 is consistent with the extension or retraction direction of the piston rod of the guide cylinder 906.

[0022] Reference Figure 5 , 6As shown, the clamping mechanism 903 includes a clamping drive cylinder 913, a top plate 914, and two sets of clamping assemblies 915. The clamping drive cylinder 913 is mounted on the frame 901. The top plate 914 is connected to the output end of the clamping drive cylinder 913. The two sets of clamping assemblies 915 are connected to the top plate 914. A sealing strip is provided between the two sets of clamping assemblies 915. The clamping drive cylinder 913 drives the two sets of clamping assemblies 915 to clamp both sides of the sealing strip.

[0023] Reference Figure 7 , 8 As shown, the clamping assembly 915 includes a push rod 916, a clamping block 917, and a spring 918. The lower end of the push rod 916 is connected to the top plate 914. The clamping block 917 is in contact with the push rod 916. One end of the spring 918 is fixed on the frame 901, and the other end of the spring 918 abuts against the clamping block 917. The clamping drive cylinder 913 drives the push rod 916 to move so that the clamping block 917 clamps or releases the sealing strip. The push rod 916 has a protrusion 919 and a recess 920 on the side opposite to the clamping block 917. The protrusion 919 and the recess 920 are connected by an inclined surface. When the clamping drive cylinder 913 drives the protrusion 919 to contact the clamping block 917, the clamping block 917 clamps the sealing strip. When the clamping drive cylinder 913 drives the recess 920 to contact the clamping block 917, the clamping block 917 releases the sealing strip. The clamping block 917 has a through hole, and the push rod 916 passes through the through hole. When the push rod is driven up and down by the clamping drive cylinder 913, the protrusion 919 and the concave part 920 respectively contact the inner wall of the through hole on the clamping block 917. When the protrusion 919 extends into the through hole, it pushes the clamping block 917 towards one side of the sealing strip, so that the clamping block 917 is pressed against the side wall of the sealing strip. At the same time, the spring 918 is compressed. When the concave part 920 extends into the through hole, it loses the push on the clamping block 917. Under the elastic restoring force of the spring 918, the clamping block 917 moves away from the sealing strip, thereby releasing the sealing strip.

[0024] In the above structure, the frame 901 is provided with an upper positioning component 921 and a lower positioning component 922, which are arranged vertically opposite each other, and a sealing strip is provided between the upper positioning component 921 and the lower positioning component 922. The lower positioning component 922 includes a lower base plate 923, a lower base 924, and a lower positioning block 925. The lower base plate 923 is fixedly connected to the frame 901, the lower base 924 is disposed on the lower base plate 923, and the lower positioning block 925 is disposed on the lower base 924. The lower positioning block 925 is used for positioning the sealing strip. The upper end face of the lower positioning block 925 is set as a contoured groove structure with the same shape as the sealing strip, so that the sealing strip can be stably placed on the lower positioning block 925. The upper positioning component 921 includes an upper top plate 926, an upper seat 927, and an upper positioning block 928. The upper top plate 926 is fixedly connected to the frame 901. The upper seat 927 is positioned above the lower base 924. The upper positioning block 928 is mounted on the upper seat 927. The sealing strip is positioned between the upper positioning block 928 and the lower positioning block 925. The lower end face of the upper positioning block 928 is configured as a contoured groove structure with the same shape as the sealing strip, which can stably position the sealing strip between the upper positioning block 928 and the lower positioning block 925. The upper positioning block 928 and the lower positioning block 925 position the sealing strip from both above and below. First, the sealing strip is fixed in place. Then, through the action of the clamping mechanism 903, two clamping blocks 917 clamp the sealing strip from both sides, thereby stably fixing the sealing strip and preventing it from shifting during the punching process. In addition, the sealing strip passes through the upper positioning block 928, the lower positioning block 925 and the two clamping blocks 917, which form a contour cavity that matches its own shape. This can prevent deformation caused by clamping while clamping the sealing strip, and ensure the accuracy of the sealing strip cutting.

[0025] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
