Push bending equipment for pipe or profile

Abstract

The invention discloses push bending equipment of pipes or sections. The push bending equipment comprises an equipment stand, a push bending mechanism is arranged on the equipment stand, a push bending radius measuring mechanism is arranged at a position, above the push bending mechanism, of the equipment stand, a feeding clamping mechanism and a discharging clamping mechanism are arranged on the equipment stand, the push bending mechanism comprises a push bending main mold device and a reverse push supporting device, sliding plate mold devices are arranged at positions, on two sides of the reverse push supporting device, of the equipment stand, the push bending main mold device comprises a main mold seat slidably arranged on the equipment stand, a push bending main mold is detachably arranged on the main mold seat, an arc-shaped forming groove is formed in a forming end of the push bending main mold, and a main oil cylinder driving the main mold seat to move is arranged on the equipment stand; the reverse push supporting device comprises a supporting oil cylinder and a supporting seat, each sliding plate mold device comprises a moving seat slidably arranged on the equipment stand and an auxiliary oil cylinder driving the moving seat, a sliding mold seat is hinged on each moving seat, a sliding plate mold is detachably arranged on each sliding mold seat, and a push bending straight groove is formed in each sliding plate mold. The push bending equipment can bend the pipes or the sections which are large in bending radius and accurate in forming.

Description

technical field [0001] The invention relates to a push-bending device for pipes or profiles. Background technique [0002] Existing push bending equipment is difficult to bend some large-scale pipes or profiles, because this kind of bending process not only requires a large thrust, but also needs to achieve continuous bending. In addition, the rebound of the material after bending is large. Some equipment cannot process finished bent pipes that meet the size requirements. For example, when processing bridge pipes with a bending radius of more than 4 times the diameter of the pipe, a wall thickness of more than 25mm, and a diameter of more than 400mm, the current general processing method is to use a rounding machine to roll them piece by piece and weld them together to form. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a push-bending device capable of bending large-bending radius and accurately formed pipes o...
