Description

Technical Field

[0001] This utility model relates to the field of shearing machines, and in particular to a swing beam shearing machine. Background Technology

[0002] A swing beam shearing machine is a common type of metal sheet processing equipment. The upper blade of the swing beam shearing machine is fixed to a blade holder, while the lower blade is fixed to the worktable. During operation, the blade holder swings back and forth around a fixed axis. This swinging motion causes the upper blade to move downwards, creating a shearing force with the lower blade, thus cutting the metal sheet placed on the worktable along the shearing line. This swinging motion ensures that the contact between the upper blade and the sheet metal is gradual during the shearing process, effectively reducing the peak shearing force and minimizing impact on the equipment and the sheet metal. However, existing swing beam shearing machines have a simple structure, unstable sheet metal fixation, and difficult-to-replace blades, significantly increasing maintenance costs.

[0003] Therefore, it is necessary to provide a swing beam shearing machine to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides a swing beam shearing machine, which solves the problems of existing swing beam shearing machines having a simple structure, unstable plate fixing, and difficult blade replacement, which greatly increases the maintenance cost of the shearing machine.

[0005] To solve the above-mentioned technical problems, this utility model provides a swing-type shearing machine, including a worktable, two support plates fixed on the worktable, and a swing frame rotatably mounted on the support plates. A first cutter is engaged at the bottom of the swing frame, and a first hydraulic rod is fixed on the swing frame. The first cutter is provided with a slot adapted to the first hydraulic rod. A second cutter corresponding to the first cutter is fixed on the worktable.

[0006] A hydraulic cylinder is fixed on the support plate, and a slide rod is fixed to the output end of the hydraulic cylinder. A limiting groove adapted to the slide rod is provided on the swing frame.

[0007] A connecting plate is fixed to the support plate by a connecting frame, and a stabilizing plate is fixed to the bottom of the connecting plate by a second hydraulic rod, and a pressure plate is fixed to the stabilizing plate.

[0008] Preferably, a contact plate is fixed to the bottom of the pressure plate.

[0009] Preferably, the support plate is provided with a slot corresponding to the hydraulic cylinder.

[0010] Preferably, the support plate is rotatably connected to the swing frame via a shaft.

[0011] Preferably, the support plate is provided with a control panel.

[0012] Preferably, the bottom of the frame is provided with a fixing groove that is adapted to the first cutter.

[0013] Compared with related technologies, the swing beam shearing machine provided by this utility model has the following beneficial effects:

[0014] This utility model provides a swing beam shearing machine. By activating a second hydraulic rod, the pressure plate on the stabilizing plate is driven, and the plate is pressed and fixed by a contact plate. Activating a hydraulic cylinder drives a sliding rod, which swings downward through a limiting groove on the swing frame that matches the sliding rod. This causes the first cutter on the swing frame to shear the plate. When replacing the first cutter, the first hydraulic rod is activated to disengage from the slot on the first cutter, allowing the first cutter to be removed for maintenance and replacement. This solves the problems of existing swing beam shearing machines, such as simple structure, unstable plate fixing, and difficulty in replacing the shearing blades, which greatly increases the maintenance cost of the shearing machine.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1-4As shown, a swing beam shearing machine includes a worktable 1, two support plates 2 are fixed on the worktable 1, and a swing frame 3 is rotatably mounted on the support plates 2. A first cutter 4 is engaged at the bottom of the swing frame 3, and a first hydraulic rod 5 is fixed on the swing frame 3. The first cutter 4 is provided with a slot 19 that matches the first hydraulic rod 5. When replacing the first cutter 4, the first hydraulic rod 5 is activated to disengage from the slot 19 on the first cutter 4, and the first cutter 4 can be removed for maintenance and replacement. A second cutter 6 corresponding to the first cutter 4 is fixed on the worktable 1 to facilitate neat cutting of the board.

[0022] The support plate 2 of this utility model is fixed with a hydraulic cylinder 7, and the output end of the hydraulic cylinder 7 is fixed with a slide rod 8. The swing frame 3 is provided with a limiting groove 9 that matches the slide rod 8. When the hydraulic cylinder 7 is started, it drives the slide rod 8. Through the limiting groove 9 on the swing frame 3 that matches the slide rod 8, the swing frame 3 is driven to swing downward, and the first cutter 4 on the swing frame 3 cuts the plate.
