A mold structure for processing bent pipe

Abstract

The invention discloses a die structure for machining a bent pipe. The die structure comprises a bending die, two clamping dies and a bottom plate. The two clamping dies are provided with a semicircular forming area and installed on the bottom plate and move in the opposite directions and the same direction. Each clamping die is connected with a triangular turnover block, wherein the turnover block is provided with a fixed end, a turnover end and a push-pull end, the fixed end is fixed to the bottom plate through the effect of a rotating shaft, an included angle not smaller than 90 degrees isarranged between the turnover end and the push-pull end, and the push-pull end is connected with the clamping die. The bending die comprises a forming portion, and is further provided with protrusionsacing on the turnover ends. The bending die descends to enable the protrusions to press the turnover ends and push the turnover ends towards the outer side. The push-pull ends will turn over around the rotating shaft on the fixed ends, and push the clamping dies to move. The bottom plate is further provided with a spring for resetting the turnover ends, the spring acts between the turnover ends and the bottom plate, the bending die is further provided with an arc hook plate for lifting, and the arc hook plate is provide with an arc area restored in the forming area direction.

Description

technical field [0001] The invention relates to the field of mold structures, in particular to a mold structure for processing bent pipes. Background technique [0002] In the process of bending pipe workpieces, pipe bending molds are needed. The pipe bending molds include clamping molds, profiling molds and bending molds, etc., and their function is to bend the plate according to the size. At present, the pipe bending molds on the pipe bending equipment are all single, and can only process one specification, and the installation is fixed, which is inconvenient to disassemble, and it needs to be debugged and calibrated after reinstallation, otherwise the product processing will be damaged make an impact. Common pipe bending molds are implemented with multiple power sources, and the power sources in at least three directions are used for mold clamping. The structure is complex, the power arrangement is inconvenient, and the equipment maintenance is troublesome. At the same ...
