Description

Technical Field

[0001] The invention relates to the technical field of flange processing, in particular to a flange forming and cutting machine. Background Art

[0002] Flange is also called flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. There are also flanges used on equipment inlets and outlets for connection between two devices, such as reducer flanges. Any connecting parts that are bolted and closed around two planes are generally called "flanges". For example, the connection of ventilation ducts can be called "flange parts", but this connection is only a part of a device. For example, the connection between flanges and water pumps is not good for calling water pumps "flange parts". Smaller ones such as valves can be called "flange parts". Flanges are usually welded on the circumference of the end of the pipe to connect pipes, valves and shafts together. Due to their good comprehensive performance, flanges are widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, pipelines, fire protection, electricity, aerospace, shipbuilding, etc. Flanges are also called flanges or flange plates. During the processing of flanges, they need to be cut and formed by corresponding forming and cutting equipment to make their size and shape meet the design requirements; the common cutting and forming equipment for flanges is lathe cutting.

[0003] At present, when turning the flange, an external clamp is generally used to clamp the outer peripheral surface of the flange, and then a turning tool is used to turn it. However, in the actual operation, the external clamp is clamped on the outer peripheral surface of the flange blank, resulting in the turning tool being unable to normally turn the contact surface between the clamp and the flange blank when turning. When limiting the inside of the flange, the flange has a small margin of movement when it is butt-jointed, and the flange is prone to collision and damage with the claws during lifting and movement.

[0051] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0052] When in use, the flange is placed on the placement table 5, the positioning column 6 is located in the middle of the flange, and then the threaded rod 41 is rotated downward on the top of the positioning column 6, and the cone 42 at the bottom of the threaded rod 41 will push the arc block 39 downward, so that the arc block 39 drives the movable rod 27 to push the L-shaped card plate 28 to the outside of the positioning column 6 until the L-shaped card plate 28 is close to the inner wall of the flange, and then the first motor 14 is started through the external switch, and the first motor 14 drives the first screw rod 15 to rotate, and the rotation of the first screw rod 15 drives the first slider 16 to descend, thereby driving the horizontal box 18 to descend through the horizontal plate 17;
