Quick replacement device for upper die of bending machine

Abstract

The invention belongs to the technical field of bending machine dies and particularly relates to a quick replacement device for an upper die of a bending machine. The problem that screws need to be repeatedly detached when the mechanical-fixing-clamping-type upper die is mounted is solved. The quick replacement device for the upper die of the bending machine comprises the upper die and a die replacement base. The bottom of the die replacement base is provided with an upper die conical mounting groove, the upper die conical mounting groove is matched with a mounting part of the upper die, and notches are symmetrically formed in the two sides of the middle of the upper die conical mounting groove and vertically run through the die replacement base. Symmetric positioning mounting holes are formed in the portion, of the die replacement base, of the two sides of each notch and run through the notches, one side of the upper portion of one positioning mounting hole is provided with a switch mounting blind hole, and the switch mounting blind hole runs through the upper die conical mounting groove. An upper die positioning assembly is installed in each positioning mounting hole and used forfixing the upper die, and a die replacement switch assembly is installed in the switch mounting blind hole and used for detaching the upper die. The quick replacement device effectively solves the problem that the fixing screws need to be repeatedly detached when the mechanical-fixing-clamping-type upper die is mounted.

Description

technical field [0001] The invention belongs to the technical field of bending machine moulds, and in particular relates to a quick mold changing device for an upper mold of a bending machine. Background technique [0002] The mold of the bending machine is the core component of the bending machine. It is the executive element for the workpiece to be bent. The mold of the bending machine is generally customized. Different workpiece sizes need to be equipped with different upper and lower molds. The bending production of complex workpieces , It is necessary to frequently replace the bending machine mold. [0003] At present, there are two main structures for the installation of the upper mold of the bending machine. The first type is the mechanical fixed clamping type. This kind of device needs to repeatedly disassemble the fixing screws. precision. This structure is a common general structure of existing bending machines, and is widely used in various bending machine produ...
