In steel structure construction, steel beams are the main load-bearing components, and their quality and precision are of vital importance. Punching is an important part of steel beam processing. Both ends of the I-beam are required to be punched with four or more mounting holes to meet different installation and assembly requirements.

[0003] The publication number is "CN113953373A", which is an end punching device for steel beam surface processing, including an operating table, a gantry is fixedly connected to the top of the operating table, a crossbeam is arranged at the top of the inner cavity of the gantry, an upper die seat is installed at the bottom of the crossbeam, a movable plate is arranged below the upper die seat, a limiting mechanism is arranged between the upper die seat and the movable plate, the limiting mechanism includes two groups of limiting grooves, two groups of reset springs, two groups of limiting blocks and two groups of connecting rods, two placing tables are symmetrically arranged above the operating table, a steel beam body is arranged at the top of the two placing tables, and an auxiliary mechanism is arranged between the two placing tables and the steel beam body. The end punching device for steel beam surface processing effectively avoids the deviation of the position of the steel beam body when punching holes through the design of the limiting mechanism and the auxiliary mechanism, and ensures the quality of the steel beam body after punching holes and the subsequent use after processing.

[0004] In the above patent, before punching the I-shaped steel beam, the two ends of the steel beam will be clamped into the inside of the limit platforms on both sides, and the end faces of the two ends of the steel beam will be limited and fixed. However, such a limit method can only clamp and fix the steel beam workpiece from the bottom of the two ends, and cannot clamp and fix it according to the I-shaped shape of the steel beam, which leads to a small area of ​​the clamping surface, affecting the stability of the larger steel beam, causing the steel beam to shake when being punched and affecting the accuracy of the punching process. For this reason, a new technical solution needs to be designed to solve the problem. Summary of the invention

[0005] The purpose of the present invention is to provide an end face punching device for processing a steel beam, which solves the problems raised in the background technology.
