[0053] The working principle of the front and rear double-sided entry bar punching device is as follows:

[0054] When the front door sealing strip needs to be punched, the front and rear double-sided strip entry punching device is installed on the punching equipment, with the strip entry front guide mechanism 23 in front. When the equipment is started, the front door sealing strip enters the double-sided strip entry punching mechanism 2 through the strip entry front guide mechanism 23 and is punched using the front end of the punching knife assembly 225.

[0055] When it is necessary to punch the rear door sealing strip, the front and rear double-sided strip entry punching device is rotated 180 degrees and installed on the punching equipment, with the strip entry rear guide mechanism 24 in front; when the equipment is started, the rear door sealing strip enters the double-sided strip entry punching mechanism 2 through the strip entry rear guide mechanism 24, and the punching process is carried out using the rear end of the punching knife assembly 225.

[0056] Example 2

[0057] The structure of the front and rear double-sided strip cutting device described in this embodiment is the same as that in embodiment 1. The difference is that a quick-change cutting tooling device 3 is also provided below the structure of the front and rear double-sided strip cutting device described in this embodiment.

[0058] like Figures 1 to 4 The quick-change punching fixture 3 shown includes: a punching platform 31, a rotating mounting plate 32, a front positioning block 333, a rear fastening block 34, a set of first rotating limit blocks 36 and second rotating limit blocks 37. The punching platform 31 has an opening. The rotating mounting plate 32 is disposed on the punching platform 31 and is located outside the opening. The punching platform 31 has a front positioning block 33 and a rear fastening block 34 respectively located at the front and rear of the rotating mounting plate 32. The middle of the left and right sides of the rotating mounting plate 32 is connected to the punching platform 31 through pins 35.

[0059] One end of the first rotating limiting block 36 is fixed to the punching platform 31; one end of the second rotating limiting block 37 is fixed to the rotating mounting plate 32, and the other end cooperates with the corresponding first rotating limiting block 36. The punching platform 31 is provided with a groove for mounting the rotating mounting plate 32 on the outer side of the opening.

[0060] The rotating mounting plate 32 is provided with a centering positioning pin 38 on the side near the front positioning block 33.

[0061] The rotating mounting plate 32 is provided with left and right limit bolts 39 on both sides of the pin 35.

[0062] The punching platform 31 is provided with at least one set of left and right limit bolts 39.

[0063] A chip sensor 310 is located below the punching platform 31.

[0064] Both the front positioning block 33 and the rear fastening block 34 are provided with inner grooves, and a chip sensor protective plate 311 is provided in the inner grooves. A second hopper 312 is provided below the punching platform 31 on the outside of the opening.

[0065] In this embodiment, a quick-change punching fixture device is described. The double-sided strip entry punching device is pushed onto the punching platform 31. The double-sided strip entry punching device moves forward under the limitation of the left and right limit bolts 9 on both sides and inserts into the center positioning pin 38 and the front positioning block 33. Finally, the rear fastening block 34 pushes against the double-sided strip entry punching device and locks it. At this time, the installation of the double-sided strip entry punching device is completed.

[0066] When switching between front and rear door punching, pull out pin 35 and push the double-sided strip punching device in the direction not blocked by the first rotation limit block 36. Since the double-sided strip punching device is fixed to the rotating mounting plate 32 by the front positioning block 33 and the rear fastening block 34, when the double-sided strip punching device is pushed, the rotating mounting plate 32 will rotate in the punching platform 31, and the double-sided strip punching device will rotate together. At the same time, the second rotation limit block 37 installed on the rotating mounting plate 32 will also rotate until it hits the first rotation limit block 36 and stops pushing the rotation. At this time, the double-sided strip punching device has rotated exactly 180 degrees. Finally, insert pin 35, and the front or rear door punching switch is completed.

[0067] It should be noted that the rotation can be driven automatically, that is, the rotating mounting plate 32 can be driven to rotate by a rotating drive cylinder or a motor. During the rotation of the rotating mounting plate 32, the double-sided strip cutting device is driven to rotate.

[0068] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
