Description

Technical Field

[0001] The invention relates to the technical field of steel structure cutting, and in particular to a cutting device for steel structure production and processing. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Steel structure is easy to rust. Generally, steel structure needs to be rust-proofed, galvanized or painted, and regular maintenance is required.

[0003] In order to solve the problem that "most general cutting devices rely on manual cutting", the Chinese patent with publication number CN213380502U discloses a shock-absorbing cutting device for steel structure production and processing, including a workbench, the top of the workbench is fixedly connected to a support leg, both sides of the bottom of the workbench are fixedly connected to hydraulic telescopic rods, the bottom ends of the two hydraulic telescopic rods are fixedly connected to a bottom plate, the bottom of the bottom plate is fixedly connected to a shock-absorbing frame, the inner cavity of the shock-absorbing frame is laterally provided with an extrusion plate that slides along the height direction of the shock-absorbing frame, the top of the extrusion plate is fixedly connected to a shock-absorbing spring, the top of the shock-absorbing spring is fixedly connected to the top of the inner wall of the shock-absorbing frame, the bottom of the extrusion plate is fixedly connected to a bottom rod, the bottom end of the bottom rod passes through the shock-absorbing frame and extends to the bottom of the shock-absorbing frame, one end of the bottom rod located outside the shock-absorbing frame is fixedly connected to a universal wheel, and one side of the top of the workbench is fixedly connected to a cutting frame. Although the existing technical problems have been solved, the following problems still exist: In this technical solution, when cutting, the cut portion of the steel structure is suspended in the air. As the cutting proceeds, the cut portion will rotate downward due to gravity, which will cause an uneven incision. Therefore, corresponding improvements are made to address this problem. Summary of the invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a cutting device for steel structure production and processing.

[0005] The present invention provides a cutting device for steel structure production and processing, comprising a base plate, a workbench and a mounting frame fixed on the top of the base plate, a cross plate arranged in the mounting frame, an electric push rod fixed on the top of the mounting frame, the cross plate fixed on the output shaft of the electric push rod, a motor 1 fixed on the bottom of the cross plate, a saw blade connected to the output shaft of the motor 1, a fixed seat fixed on the inner side surface of the mounting frame, a support plate connected to the fixed seat via a rotating shaft, a pushing assembly arranged on the workbench, the support plate connected to a transmission assembly, the steel structure is placed on the workbench, and then the steel structure is pushed to one side of the saw blade through the pushing assembly, when the steel structure is pushed to a predetermined position, the output shaft of the electric push rod drives the cross plate and the saw blade to move downward, and at the same time, the motor 1 drives the saw blade to rotate, so that the steel structure can be cut by the saw blade, and when the cross plate moves downward, it drives the support plate to rotate upward to a horizontal position through the transmission assembly, thereby supporting the steel structure together with the workbench, thus avoiding uneven incisions.

[0006] Preferably, the pushing assembly includes a second motor fixed at the end of the workbench, the output shaft of the second motor is connected to a screw that passes horizontally through the workbench, a slide groove is provided on the top of the workbench, and a push plate that is slidably connected in the slide groove and forms a threaded connection with the screw, when the second motor is started, the output shaft of the second motor drives the screw to rotate, and the screw drives the push plate to move, thereby pushing the steel structure.

The pressure plate has a downward eight-shaped opening, and a pair of notches for the pressure plate to enter are opened on the workbench. An elastic connection is formed between the pressure plate and the transverse plate. When the transverse plate moves downward, the pressure plate will first contact the steel structure, and then gradually press the steel structure downward. Since the pressure plate has a downward eight-shaped opening, it not only applies downward pressure to the steel structure, but also can correct the steel structure from both sides, thereby ensuring the accurate position of the steel structure.

[0011] Preferably, a second spring is sleeved on the guide rod, and two ends of the second spring are respectively fixedly connected to the pressure plate and the cross plate, so that an elastic connection can be formed between the pressure plate and the cross plate through the second spring.

[0016] 3. A cutting device used for the production and processing of steel structures. By setting a fork rod, when the cross plate moves downward, it simultaneously drives the support rod to move. The support rod will press the fork rod downward, so that the support plate will rotate upward to a horizontal position and then be restricted in the horizontal position by a limit block.
