Problems solved by technology

[0002] Bending dies with different curvatures are required in the local bending forming process of composite curved pipe fittings. If the bending dies are replaced manually, the processing efficiency will be extremely low, and even the processed pipe fittings will be scrapped due to the wrong selection of bending dies by the operator.
In order to solve the above problems, there is a lack of an automatic bending die changing device in the prior art to meet the demand

Abstract

The invention discloses an automatic bending die replacing device and method for sectional bending forming of multi-curvature elbows. According to the automatic bending die replacing device, a rotating assembly is arranged on a base, the bottom of a bending die library is connected to the rotating assembly through a rotating shaft, the rotating assembly drives the bending die library to rotate around the rotating shaft, a bending die sliding block and a guide rail form a linear pair to be fixed to the base, a single-axis linear air cylinder is fixed on the position, between the guide rail andthe rotating assembly, of the base, an air cylinder rod of the single-axis linear air cylinder is fixedly connected to an air cylinder fixing plate, the air cylinder fixing plate is arranged on the rotating shaft in a sleeving manner, and a double-axis linear air cylinder is fixed to the air cylinder fixing plate. The automatic bending die replacing device and method have the advantages that a bending die can be automatically replaced in the local bending forming process of the elbows, and the automatic bending mold replacing device and method can be used for completing sectional machining ofthe multi-curvature elbows.

Description

technical field [0001] The invention belongs to the field of bending forming of multi-curvature thin-walled pipe fittings, and in particular relates to an automatic bending die changing device and method for segmental bending forming of multi-curvature bent pipes. Background technique [0002] Bending dies with different curvatures are required in the local bending forming process of composite curved pipe fittings. If the bending dies are replaced manually, the processing efficiency will be extremely low, and even the processed pipe fittings will be scrapped due to the wrong selection of bending dies by the operator. . In order to solve the above problems, there is a lack of an automatic bending die changing device in the prior art to meet the demand. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and propose an automatic bending die changing device and method for multi-curvature elbow segmental be...
