Description

Technical Field

[0001] The present application relates to the technical field of automobile sealing strip processing, and in particular to an adaptive sealing strip punching device. Background Art

[0002] Automobile sealing strips can fill various gaps and crevices between components of the vehicle body, and have functions such as shock absorption, waterproofing, dustproofing, sound insulation, and decoration, which can improve the comfort of driving experience and protect the vehicle body. During the production and preparation process, automobile sealing strips need to be punched into the required length. In the early days, the conventional processing method was to manually place the sealing strips and then punch them with a tool. However, due to the characteristics of the sealing strips, they are prone to bending during operation, which makes punching difficult and may also affect the cutting size.

[0003] At present, the punching process is gradually mechanized and automated. Relevant prior art, such as the Chinese patent application "A punching machine for automobile sealing strips", application number: CN202321666589.X; discloses that the upper and lower surfaces of the automobile sealing strip are both smooth surfaces, including a frame, the frame is provided with a slot for placing the automobile sealing strip, and the two ends of the corresponding slot on the frame are respectively provided with blanking holes; a linear drive mechanism is installed above the corresponding slot on the frame, and the lower end of the linear drive mechanism is connected to a bearing plate, and the bearing plate is driven by the linear drive mechanism to move in the vertical direction; the sealing strip can be pressed and fixed by the pressure plate when punching the sealing strip, so that it is not easy to bend so as to facilitate punching, and the adsorption hole on the bottom surface of the movable pressure plate can rise after punching and adsorb the sealing strip placed in the slot for easy removal, and the overall operation is more convenient and quick.

[0004] The above patent application is mainly aimed at a linear sealing strip structure. The ends of some sealing strips are curved, so the above punching machine is not suitable and other sealing strip punching machines are required for processing. Utility Model Content

[0005] The technical problem to be solved by the present application is to provide an adaptive sealing strip punching device, in which a mounting position is set on a frame, and the mounting position is detachably equipped with a horizontal punching device and an inclined punching device, so as to expand the adaptability of the device and adapt to the punching of different sealing strips.

[0006] The technical solution adopted in the present application is: an adaptive sealing strip punching device, including a frame, at least one mounting position is provided on the frame, a punching device is detachably installed at the mounting position, the punching device includes a mounting plate, a punching seat and a mounting seat, the mounting seat and the punching seat are fixed on the mounting plate or on a substrate, the substrate is connected to the mounting plate through an inclined pad, the mounting plate is horizontally installed on the mounting position, the mounting seat and the punching seat fixed on the mounting plate are horizontally arranged, and the mounting seat and the punching seat fixed on the substrate are inclinedly arranged.

[0007] Compared with the prior art, the advantages of the present application are that, firstly, a mounting position is set, and a detachable installation punching device is realized through the mounting position, so the present application also expands the application of the equipment, and different sealing strip products can be adapted by replacing different punching devices. Compared with the replacement of the whole machine, the present application is more economical and has lower processing costs. Secondly, the punching device of the present application mainly includes two types in order to adapt to curved sealing strips and linear sealing strips. First, the mounting seat and the punching seat are fixed on the mounting plate, and the mounting plate is horizontally mounted on the mounting position. The mounting seat and the punching seat fixed on the mounting plate are also horizontally arranged, forming a horizontal punching device in the present application, which is adapted to the punching of linear sealing strips. Second, the mounting seat and the punching seat are fixed on the substrate, and the substrate is connected to the mounting plate through an inclined pad. The mounting seat and the punching seat fixed on the substrate are inclinedly arranged, forming an inclined punching device in the present application, which is adapted to the punching of curved sealing strips.

[0008] In some embodiments of the present application, the top of the mounting seat is adapted to the inner space of the sealing strip, and the sealing strip is installed on the mounting seat, and the top of the mounting seat is embedded in the sealing strip. The sealing strip is generally not a completely solid structure, and the embedded installation method well simulates the installation condition of the sealing strip, fills the gap in the sealing strip, avoids deformation of the sealing strip during punching, and improves the punching accuracy of the sealing strip.

[0009] In some embodiments of the present application, a punching cylinder, a pressing block and a punching tool are installed on the punching seat, and the punching cylinder drives the pressing block and the punching tool to move up and down when working.

The pressure block is connected to the power block through a spring assembly, realizing a floating connection of the pressure block, that is, the pressing part of the pressure block is pressed on the sealing strip in a process of gradually increasing pressure. When the punching tool punches the sealing strip, the pressure of the pressure block on the sealing strip reaches the maximum.

[0014] In some embodiments of the present application, the punching tool is attached to the rear side of the pressing block, and the punching tool moves downward along the rear side of the pressing block to cause relative displacement.

[0015] In the present application, the punching tool is further attached to the rear side of the pressing block to limit the movement trajectory of the punching tool, thereby ensuring that the movement trajectory of the punching tool is reliable, thereby improving the punching accuracy.

[0016] In some embodiments of the present application, the bottom of the punching tool is a punching blade, which includes an upward cutting edge located in the middle of the punching blade, and the two sides of the cutting edge are connected to horizontally arranged blades.
