Description

Technical Field

[0001] This utility model belongs to the field of sheet metal bending technology, and in particular relates to a sheet metal bending device for shipbuilding. Background Technology

[0002] Sheet metal bending is a metal processing technique that uses specific molds and equipment to bend sheet metal into predetermined angles and shapes to form desired parts or components. It is widely used in the automotive, aerospace, construction, and furniture industries, and is one of the key processes in manufacturing metal structural components.

[0003] In the shipbuilding industry, plate bending devices are needed to bend plates to meet usage requirements. The problem with the above technology is that most existing plate bending devices do not have the ability to limit plates of different thicknesses and specifications. Each time different thickness plates are placed, it takes a long time to adjust, which is inconvenient. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a shipbuilding plate bending device that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a shipbuilding plate bending device includes a control box and a support plate. The support plate is installed on the top of the control box. A connecting plate is installed on the top of the support plate. An extrusion assembly is provided on the top of the connecting plate. A pressure plate is provided on the top of the connecting plate. A stabilizing rod is provided at the bottom of the pressure plate. A stabilizing block is sleeved on the surface of the stabilizing rod. A lifting assembly is provided on one side of the two stabilizing rods facing each other. A positioning block is provided on the top of the connecting plate.

[0006] The extrusion assembly is used for bending and extruding the sheet material;

[0007] The lifting assembly is used for lifting and lowering control of the pressure plate.

[0008] For bending and extruding the sheet metal, preferably, the extrusion assembly includes a support arm, a support block is mounted on the top of the support arm, a hydraulic cylinder is mounted on the top of the support block, and an extrusion block is mounted on the output end of the bottom of the hydraulic cylinder.

[0009] In order to control the lifting of the pressure plate, preferably, the lifting assembly includes a motor, the output end of the motor is equipped with a threaded rod, and the top of the threaded rod is provided with a threaded plate.

[0010] To enhance the stability of the pressure plate during movement, preferably, the surface of the stabilizing rod is in contact with the stabilizing block, and the bottom of the stabilizing block is fixedly connected to the connecting plate.

[0011] In order to support the support block, preferably, the bottom of the positioning block is fixedly connected to the connecting plate, and the bottom of the support arm is fixedly connected to the connecting plate.

[0012] In order to bend and extrude the sheet metal, preferably, the bottom end of the extrusion block is rounded, and the two hydraulic cylinders are electrically connected.

[0013] In order to control the lifting and lowering of the pressure plate, preferably, the bottom of the motor is fixedly connected to the connecting plate, the surface of the threaded rod is threadedly connected to the threaded plate, and both sides of the threaded plate are fixedly connected to the stabilizing rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention solves the problem that most existing sheet metal bending devices lack the ability to limit the movement of sheets of different thicknesses and specifications, and require lengthy adjustments each time different sheet thicknesses are placed, which is quite inconvenient. The invention utilizes a combination of an extrusion assembly, a lifting assembly, a pressure plate, a stabilizing rod, and a stabilizing block. When the motor is started, it drives a threaded rod to rotate, which in turn controls the movement of a threaded plate. The threaded plate then contacts the sheet metal, thus limiting its movement. The motor is then turned off, and two hydraulic cylinders are activated simultaneously to control the movement of the extrusion block, which compresses and bends the sheet metal.
