Central air duct punching tooling structure

Abstract

This utility model provides a central air duct punching fixture structure, including a movable base frame, a processing table on the top of the movable base frame, a central punching mechanism at the top center of the processing table, and side cutting mechanisms on both sides of the central punching mechanism. In this utility model, the central punching mechanism at the top center of the processing table allows for the processing of the central air duct. First, the protruding part of the central air duct is pressed together by the lower and upper fixed seats. Then, the central cutter moves to cut the material in the central air duct. Simultaneously, multiple punching motors are installed on the equipment platform at the top of the upper fixed seat. When the punching motors descend, their front punching drills can face multiple fixed plates of the air duct, thereby punching holes in the fixed plates at various points in the air duct, facilitating subsequent installation and fixing of the air duct.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the central air duct punching fixture structure of this utility model has the following features: a sliding sleeve is provided on one side of the top plate 10, and a guide rod 14 is slidably mounted inside the sliding sleeve. The bottom of the guide rod 14 is connected to the support base plate 6, and a cylinder cross arm is connected to the top of the guide rod 14. A clamping cylinder 13 is installed on the top of the cylinder cross arm, and the output end of the clamping cylinder 13 is connected to the top plate 10. The clamping cylinder 13 mainly drives the top plate 10 to move up and down, and the top plate 10 is supported by the guide rod 14 when it moves up and down, thus ensuring high stability.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the central air duct punching fixture structure of this utility model specifically comprises a central punching mechanism 4 consisting of a movable seat 15, a lower fixed seat 16, a central cutter 17, and an upper fixed seat 18. The central cutter 17 is installed on one side of the movable seat 15 and is located on the side of the lower fixed seat 16. The central cutter 17 is mounted on the movable seat 15, and the movable seat 15 is movably mounted on the guide rail. The movable seat 15 is pulled by a cylinder when it moves.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the central air duct punching fixture structure of this utility model specifically includes an upper fixed seat 18 movably mounted on the top of the lower fixed seat 16.

[0027] This utility model discloses a central air duct punching fixture structure. During air duct processing, the fixture is placed on a processing table 3. A side cutting mechanism 2 is installed on the top side of the processing table 3. During cutting, the clamping cylinder 13 drives the top plate 10 and the upper pressure seat 11 mounted at the bottom of the top plate 10 to move downwards. The upper pressure seat 11 and the lower pressure seat 12 work together to clamp and limit the end of the air duct. Then, the cutting cylinder 9 drives the side cutting blade 8 towards the fixed point of the air duct, cutting the clamped portion of the air duct and removing the exposed clamped portion at the end of the air duct. This application also includes a central punching mechanism 4 at the top center of the processing table 3. Structure 4 mainly performs waste removal and punching of fixing plates in the middle of the air duct. When processing the middle of the air duct, the protruding part in the middle of the air duct is first pressed by the lower fixing seat 16 and the upper fixing seat 18. The upper fixing seat 18 can be driven to move downward by the lifting cylinder 22, and then cooperate with the lower fixing seat 16 to press the middle of the air duct. Then the middle cutter 17 moves and cuts the material in the middle of the air duct. At the same time, multiple punching motors 21 are also installed on the equipment platform 19 at the top of the upper fixing seat 18. When the punching motor 21 descends, the punching drill bit at the front end of it can face multiple fixing plates of the air duct, and punch holes in the fixing plates at various parts of the air duct, so as to facilitate the subsequent installation and fixing of the air duct.
