Description

Technical Field

[0001] The utility model belongs to the technical field of bending machines, in particular to a bending machine frame with a feeding device. Background Art

[0002] A bending machine is a mechanical equipment used for metal processing, which is mainly used to bend metal sheets along a pre-set bending line to form the required angle and shape.

[0003] The existing bending machine with a feeding device mainly includes a frame, a workbench, upper and lower molds, a cantilever beam and a hydraulic system.

[0004] During the operation of the bending machine, the hydraulic system drives the upper die to move upward quickly, and when it stops, it will generate an upward impact force. In order to avoid the frame rigidity of the bending machine with a feeding device being insufficient, resulting in deflection or deformation when processing large or high-strength materials, most of them are welded into a whole with steel plates.

[0005] If the bending machine frame is welded into a whole by steel plates, it needs to be replaced as a whole if it is damaged, which causes certain waste.

[0006] In view of this, how to solve the defects in the above technical solutions has become one of the problems to be solved urgently in the field of bending machine technology. Utility Model Content

[0007] In view of the problems existing in the background technology, the utility model provides, on one hand, a bending machine frame with a feeding device, including a machine body, and a top plate is arranged on the machine body, and the top plate and the machine body are detachably connected, and the machine body includes two groups of opposite first support plates and second support plates, and at least one group of connecting blocks are welded on the outer walls of the first support plates and the second support plates, and a card slot is opened on the connecting block; the top plate is provided with a protective plate, and the inner wall of the protective plate is provided with at least one group of card blocks, and the card blocks are used in conjunction with the card slots for card connection.

[0008] Optionally, the top plate and the protection plate are integrated into one body, and the protection plate is provided with a bent end portion.

[0010] Optionally, the bending machine frame also includes a cantilever beam, and the cantilever beam is clamped to the connecting bracket.

[0011] Optionally, a clamping plate is provided on the bracket near the cantilever beam.

[0012] A clamping groove is welded on the top end of the cantilever beam, and a connecting clamping plate is clamped in the clamping groove.

[0013] Optionally, a shock absorber is provided between the card plate and the card slot, the shock absorber comprises a shock absorbing sleeve, and a shock absorbing pad is fixedly installed at the bottom end of the shock absorbing sleeve and fixedly installed in the card slot.

[0014] Optionally, a shock absorbing part is installed in the shock absorbing sleeve near the shock absorbing pad, and the other end of the shock absorbing part passes through the shock absorbing sleeve and is fixedly connected to a shock absorbing tube. A shock absorbing spring is installed in the shock absorbing tube, and the shock absorbing spring passes through the shock absorbing tube and is connected to a connecting piece, and is fixedly installed on the bottom end of the card plate through the connecting piece.
