Technical Field

The application relates to the field of bending machines, in particular to an angle adjusting device for bending of a bending machine.

Background

The manufacturing process of the server chassis includes cutting, punching, bending, and mounting, and when bending such thin plates, bending operation is generally performed using a bending machine.

Chinese patent publication No. CN204052609U has announced a numerical control bending machine is with mould of bending relates to a mould, mainly includes the bottom plate, goes up mould, left lower mould and right lower mould, the left and right sides of bottom plate is fixed left side board and the right side board of being equipped with respectively, be equipped with adjusting plate between left side board and the left lower mould, left side board, left lower mould, adjusting plate adopt screw fixed connection, be equipped with adjusting plate between right side board and the right lower mould, the side of right side board still is equipped with the locating piece, right side board, right lower mould, adjusting plate and locating piece adopt screw fixed connection. The lower mould of bending of co-ordination adjusting plate, the degree of depth of adjustment lower mould of bending can be changed according to actual need to the lower mould of bending of co-ordination, satisfies the demand of the less work piece processing of angle of bending. And a positioning block is added on the right side plate, so that the workpiece can be conveniently and accurately positioned and corrected in the machining process by manpower. The positioning block is provided with a U-shaped slotted hole, which is mainly convenient for adjusting the height of the positioning block. After the adjustment is completed, the workpiece is placed between the left lower die and the right lower die, the workpiece is placed flat by using the positioning block, the upper die is pressed downwards, and the workpiece is bent and formed.

To the correlation technique among the above, when adjusting the angle of bending, need change the lower mould of bending of co-altitude, when the panel of the multiple angle of bending of needs processing, need prepare a plurality of lower moulds of bending, the cost is higher.

Disclosure of Invention

In order to reduce cost when processing into multiple angle of buckling with panel, this application provides an angle of bending adjusting device for bender.

The application provides a angle adjusting device that bends for bender adopts following technical scheme:

the utility model provides an angle adjusting device that bends for bender, includes workstation, frame, installs cover half on the workstation, installs movable mould and the relative movable mould of drive movable mould under the frame along the first driving piece that vertical direction removed, the movable mould is relative with the cover half position, the movable mould is close to feeding one side and installs angle positioning assembly, angle positioning assembly includes a plurality of angle positioning component that set up along movable mould length direction, angle positioning component includes the butt bolt of threaded connection in movable mould one side.

Through adopting above-mentioned technical scheme, during processing panel, need the manual work to arrange panel in the workstation on, the place that needs buckle aligns with the cover half, and first driving piece starts the back, drives the movable mould and removes to cover half one side, with panel position of bending after pushing down, and manual with panel feeding one side upwards break off with the fingers and thumb, and the panel tip supports the cover half, supports the butt bolt until the panel lateral wall, forms required angle of bending. When the angle that the panel needs to be bent changes, the degree of depth of adjustment butt bolt can, when the degree of depth that the butt bolt penetrated the movable mould is great, the stroke of bending is more, therefore the angle of bending is less. The setting of butt bolt can be for the angle location of bending of panel, need not to change the mould, and the cost is reduced has improved regulation efficiency simultaneously.
