Description

Technical Field

[0001] The present application relates to the technical field of elbow shaping equipment, and in particular to a half-piece shaping device for butt-welded elbows. Background Art

[0002] In the process of making elbows, steel plates need to be pressed into a semicircular shape first, and then the two steel plates are welded together. In this process, the shape and size of the elbow will change after welding, so another shaping process is needed to finalize the elbow and achieve the required dimensional accuracy and shape accuracy.

[0003] At present, a Chinese patent announcement with announcement number CN210146688U discloses an elbow shaping device, which includes a bottom plate, a gate-shaped bracket fixedly arranged in the middle of the bottom plate, an upper shaping die which can be moved up and down by a first hydraulic cylinder on the inner side of the gate-shaped bracket, a horizontal guide rail fixedly arranged on the bottom plate, the horizontal guide rail passes through the bottom of the gate-shaped bracket, a first lower shaping die and a second lower shaping die which can be moved on the horizontal guide rail, and a second hydraulic cylinder and a third hydraulic cylinder which are respectively used to drive the first lower shaping die and the second lower shaping die to move are arranged on the bottom plate. The upper shaping die is provided with two lower shaping dies, and in the process of shaping by the upper shaping die and one of the lower shaping dies in cooperation, the operator can place the elbow to be shaped later in the other lower shaping die in advance through the ceiling, and this period of time just overlaps with the time used for the elbow being shaped, so a lot of time can be saved and work efficiency can be improved.
