[0002] In the past, the punching stations of the equipment were arranged in the form of double-sided double cavities, and each punching station was arranged equidistantly. However, due to the gaps between each station, the equipment became very long after being arranged in sequence, and occupied a large area, which was not conducive to the layout of the site and had low space utilization.

[0003] At the same time, the previous double-sided double-cavity punching tooling has different punching angles required for the products, and each one will be separately equipped with a cylinder or oil cylinder as the punching power.

[0076] The working principle of the sealing strip punching device with adjustable strip insertion angle described in this embodiment is as follows: 1): the product is mounted on the strip mounting sheet metal 31171 under the positioning guidance of the strip mounting positioning module 5;

[0077] 2): The conveying drive assembly 25 drives the synchronous belt main wheel 22 to rotate, and the synchronous belt main wheel 22 will rotate through the synchronous belt 24 and the synchronous belt driven wheel 23 during operation;

[0078] 3): The trolley rotating conveying mechanism 311 is driven by the synchronous belt 24 to the punching standby position. At the same time, the trolley rotating conveying mechanism 311 is guided by the mutual cooperation of the annular inclined guide rail 27 and the inclined guide wheel 3116 during the movement, and the offset gap in the left and right directions is eliminated, which lays a good foundation for the subsequent engagement with the trolley pressure strip rotating driving mechanism 312;

[0079] 4): The lifting drive mechanism 32 drives the trolley beading rotating drive mechanism 312 to descend, and the third groove 31211 on the upper track wall plate 3121 in the trolley beading rotating drive mechanism 312 and the second positioning protrusion 31241 on the beading semicircular gear 3124 engage with each other, and the strip loading trolley is in a locked state at this time; the upper and lower semicircular tracks of the upper and lower parts and the beading semicircular gear 3124 and the strip loading semicircular gear 3114 are combined into one, and the beading assembly 3125 presses the sealing strip onto the strip loading sheet metal 31171; at the same time, the trolley rotating conveying mechanism 311 is locked in the front, back, left and right directions under the downward pressure engagement of the trolley beading rotating drive mechanism 312;

[0080] 5): The rotary drive motor 31261 of the trolley layer strip rotary drive mechanism 312 drives the power gear 31262 to rotate, and the power gear 31262 drives the gear rotating assembly of the layer strip semicircular gear 3124 and the installation strip semicircular gear 3114, which are combined into one, to rotate along the track that is combined into one of the upper semicircular track and the lower semicircular track, and stops after the product is rotated to the required angle;

[0081] 6): The integrated punching device 4 moves forward to punch the product. After the punching is completed, the integrated punching station 4 moves backward, that is, the punching plate 471 moves downward under the drive of the punching drive mechanism 472 and collides with the force block 434 of the single-sided multi-cavity punching tool. The force block 434 drives the punching assembly 433 to punch until the upper power limit reference block 473 installed on the punching plate 471 and the lower power limit block 412 on the single-sided multi-cavity punching tool are supported. At this time, the punching plate 471 stops moving downward, and the punching of the sealing strip is completed. Then, the punching plate 471 returns upward under the drive of the punching drive mechanism 472;
