Description

Technical Field

[0001] The utility model relates to the technical field of gantry shears, in particular to a novel material pressing device for gantry shears. Background Art

[0002] The traditional pressing device adopts a rectangular structure. During the pressing process, the center of gravity of the pressing device will shift, which greatly reduces the pressing effect. In addition, the traditional pressing device has no pressing teeth, which makes it easy for the material to slip during the pressing and shearing process. Utility Model Content

[0003] The utility model aims to at least solve the problem in the prior art that the center of gravity of the material pressing device is poorly stable and easily deflected.

[0004] This solution provides a new type of material pressing device for gantry shears, which is achieved by the following specific technical means: comprising a gantry frame, the top of which is connected to a material pressing mechanism via a material pressing cylinder;

[0005] The pressing mechanism includes a frame connected to the telescopic end of the bottom side of the pressing cylinder. The side edge of the frame is slidably connected to the side frame of the gantry. At the same time, multiple groups of pressing teeth are distributed on the bottom side of the frame to facilitate shearing and prevent the material from sliding during the shearing process.

[0006] Preferred technical solution 1: A guide rail is fixed on the side frame of the gantry, and a guide bar sliding along the guide rail is fixed on the side of the frame. When the pressing cylinder is running, the pressing cylinder slides downward through the guide bar.

[0007] Preferred technical solution 2: The front side of the frame is further staggered with grooves and convex edges, and the pressing teeth are distributed on the bottom side of the frame and the bottom side of the convex edge.

[0008] Preferred technical solution three: the flange is welded to the frame, and the pressing teeth are welded to the frame and the bottom of the flange to form a stable structure.

[0009] Preferred technical solution four: the guide bar is assembled with the frame by bolts.

[0010] The above structure enables this solution to have the following beneficial effects:

[0011] 1. Stronger stability: Compared with the traditional pressing head, it adopts an inclined structure, which is more stable and has stronger pressure resistance. During the pressing process, the center of gravity is no longer offset, which makes the pressing effect better;

[0012] 2. The material pressing tooth structure is adopted, which presses the material more tightly and more steadily, facilitates shearing, and prevents the material from sliding during the shearing process. BRIEF DESCRIPTION OF THE DRAWINGS
