Pipe bending mold for oil press

Abstract

The invention discloses a pipe bending mold for an oil press. The pipe bending mold sequentially comprises an upper mold base body, an upper mold correction mechanism, an upper mold block, two lower mold blocks, a lower mold correction mechanism and a lower mold base body from top to bottom. The upper mold base body is fixed to the surface of an installation table of the upper portion of the oil press. The upper mold correction mechanism is connected with the upper mold base body. The upper mold block is detachably connected with the upper mold correction mechanism. The lower mold base body is fixed to the surface of an installation table of the lower portion of the oil press. The lower mold correction mechanism is connected with the lower mold base body. The two lower mold blocks are installed on the lower mold base body in a bilateral symmetry mode and rotate freely on the lower mold base body. The upper mold correction mechanism corresponds to the lower mold correction mechanism in position. The pipe bending mold has the characteristics that automatic correction is achieved, the lower mold blocks can reset automatically, and an upper mold and a lower mold are replaced conveniently.

Description

technical field [0001] The invention relates to a pipe bending die for a hydraulic press, belonging to the technical field of pipe bending dies. Background technique [0002] At present, the common pipe bending processing in the domestic market mostly adopts pipe bending machine with pipe bending mold for cold processing or induction heating with pipe bending forming mold for hot processing. However, for companies that do not have corresponding processing equipment but only equipped with hydraulic machines, they want to perform pipe bending. Processing needs to be equipped with corresponding bending dies for bending, and the processed parts are only some parts with low forming angles and low appearance quality requirements. For example, the existing patent provides a hydraulic pipe bending machine die (CN201799528U), which uses static pressure The mold and the dynamic pressure mold work together for bending, but this device still has the following problems: the static pressu...

[0002] At present, the common pipe bending processing in the domestic market mostly adopts pipe bending machine with pipe bending mold for cold processing or induction heating with pipe bending forming mold for hot processing. However, for companies that do not have corresponding processing equipment but only equipped with hydraulic machines, they want to perform pipe bending. Processing needs to be equipped with corresponding bending dies for bending, and the processed parts are only some parts with low forming angles and low appearance quality requirements. For example, the existing patent provides a hydraulic pipe bending machine die (CN201799528U), which uses static pressure The mold and the dynamic pressure mold work together for bending, but this device still has the following problems: the static pressure mold and the dynamic pressure mold are fixedly connected and cannot be replaced, and the static pressure mold located below is arc-shaped, and the bending When bending, it is necessary to configure the corresponding pipe fixing device or use manual methods
