Description

Milling machine mould of bending and have bender of this mould

Technical Field

The utility model relates to a bender mould design field, in particular to milling machine mould of bending and have bender of this mould.

Background

The bending machine is important equipment for bending and forming workpieces in the sheet metal industry, mainly refers to a plate bending machine, and is used for bending metal plates according to process requirements so as to press the metal plates into parts in various shapes. The bending die is a tool for forming and processing a plate by a bending machine, and mainly realizes the processing of the appearance of an article by changing the physical state of a formed material, so that the plate becomes a workpiece with a specific shape and a specific size under the action of the pressure of the bending machine.

The bending machine mainly comprises a rack and a workbench, the rack is fixedly connected with the workbench, an upper die is arranged on the rack and comprises a die shank and a bending knife, the die shank is connected with the rack in a sliding mode and is connected with a hydraulic system, a lower die with a bending groove is arranged on the workbench, and the bending knife and the lower die are arranged in the same vertical plane. When the bending machine is used, a workpiece to be bent is placed on a lower die of a workbench, a hydraulic system drives a bending knife to move towards the direction close to the lower die, and when the bending knife contacts the workpiece to be bent, the bending knife continues to move until the bending knife presses the workpiece to be bent into a bending groove of the lower die. At the moment, the workpiece is bent, and the hydraulic system drives the bending knife to move towards the direction far away from the lower die, so that the bent workpiece can be taken out.

The bending machine has the following problems: because the tool bit of bending sword generally is sharp, so the position of bending of the work piece of bending generally is the right angle, but some work pieces of waiting to bend need bend into the fillet of different radians, when the work piece to the different demands of buckling is bent the operation, need use rather than corresponding bending sword and lower mould, because the holistic weight of bending sword is great, when changing the bending sword, need two people to cooperate, alone will bend the sword and lift the position of waiting to fix, another people fixes through screwing up or loosening bolt fifty percent discount bending sword, it is convenient inadequately so to change the bending sword.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a milling machine mould of bending and have bender of this mould reaches the effect of being convenient for change the sword of bending.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a milling machine mould of bending, includes the sword of bending, the sword of bending includes handle of a knife and blade, and the top fixed connection of handle of a knife and blade can be dismantled fixedly connected with columnar tool bit in the bottom of blade.

Through adopting above-mentioned technical scheme, the tool bit is the column back, can be with work piece bending type be certain fillet, and fixed connection back can be dismantled with the blade to the tool bit simultaneously, when the different fillets of needs roll over, pulls down the tool bit from the blade, then more renews the new tool bit, compares in changing whole bending knife, and the weight of tool bit is lighter, makes things convenient for the staff to change the tool bit as required, improves the convenience of using.
