Description

Technical Field

[0001] The utility model belongs to the technical field of H-shaped steel punching, and specifically relates to an H-shaped steel hydraulic punching device. Background Art

[0002] H-shaped steel is a common engineering structural steel with an H-shaped cross-section. It is usually used in construction, bridges, machinery manufacturing, shipbuilding and other fields. The cross-section of H-shaped steel is H-shaped, with a large cross-sectional area and moment of inertia, which makes it have higher bending stiffness and load-bearing capacity.

[0003] In the existing technology, the H-shaped steel is usually fixed on the workbench, and the staff uses a drill to punch the H-shaped steel. Since the H-shaped steel needs to be perforated with multiple installation bolts during the structural installation process, and the perforation and hole spacing sizes vary, it may be inconvenient to press down and position the H-shaped steels of different sizes during the punching process, which may cause the H-shaped steel to shift during the punching process. At the same time, it is not convenient to flexibly adjust the pressing state of the H-shaped steel, and then it is not convenient to adjust the distance between two adjacent holes. Secondly, it is impossible to punch holes on the same horizontal line of the H-shaped steel waist plate;

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0008] A positioning hole is provided at the top of the side plate, and a positioning rod is fixedly connected to the bottom of the card plate. The inner circumference of the positioning hole is equal to the outer circumference of the positioning rod. By providing the positioning hole and the positioning rod, the accuracy of the up and down movement adjustment of the card plate is increased.

[0009] The outer side wall of the frame plate is fixedly connected with a hydraulic rod, the telescopic end of the hydraulic rod is fixedly connected with a movable rod, the end of the movable rod away from the hydraulic rod is fixedly connected with a punching rod, the outer circumference of the punching rod is smaller than the outer circumference of the movable rod, and the H-shaped steel body is punched by hydraulic driving by arranging the hydraulic rod, the movable rod and the punching rod.

[0010] The side plate is provided with a through hole, the inner circumference of the through hole is larger than the outer circumference of the punching rod, and the movable rod is slidably connected to the side plate through the through hole. By providing the through hole, it is convenient for the punching rod to penetrate the interior of the side plate, while increasing the stability of the movement of the movable rod.

[0011] The top of the punching table is fixedly connected with an ear plate, and the ear plate is rotatably connected with a transmission roller, and the transmission roller is rollingly connected to the H-shaped steel body.

Then, through the action of the punching rod, the H-shaped steel body positioned under the pallet is punched, so that holes in a linear array or arranged according to needs can be opened on both sides of the top of the H-shaped steel body.

[0015] The ear plate and the driving roller are used in coordination to facilitate the movement and adjustment of the H-shaped steel body, and the bottom plate is used to facilitate the movement of the H-shaped steel body through the punching area. BRIEF DESCRIPTION OF THE DRAWINGS
