Abstract

The utility model discloses a plate shearing machine which comprises an upper die and a lower die. Cutters and a hold-down device are arranged on the upper die, wherein the hold-down device is used for pressing a plate and preventing position deviation of the plate when the plate is sheared. The lower die is provided with a workbench which enables a plate body to pass through, at least one first plate flattening mechanism is arranged above the workbench, the first plate flattening mechanism comprises a cross beam, the cross beam is horizontally arranged on the upper die and is located at the position of the front end of the hold-down device, a mounting seat is fixedly arranged below the cross beam, and a first compression roller is arranged in the mounting seat in a rotating mode. According to the plate shearing machine, the plate is flattened before entering a cutter position, and therefore the accuracy of the plate body after being sheared is guaranteed. Moreover, when the plate is sheared, the plate is pressed all the time, and thus the plate is not bent and is kept flat in the shearing process.

Description

Plate shearing machine

Technical field

The utility model relates to cutting equipment, is specifically related to a kind of plate shearing machine that cuts for plate body.

Background technology

Plate shearing machine is a kind of accurate control sheet material processing dimension, bulk metal sheet material is carried out automatic circulation shear processing, and be transported to the automatically processing device of subsequent processing by stack pallet, sheet material is being carried out in the shear history, adopt Programmable Logic Controller that automatic clipper is controlled, the length of sheet material cutting is by the block control that is provided with behind cutter, and promptly the distance of cutter and block is the length of cutting gained sheet material.

Before sheet material is sent into plate shearing machine, generally all use level(l)ing machine that plate body is flattened, smooth to guarantee plate body, guarantee plate body on plate shearing machine, cut length be the actual length that obtains.But plate body is sent into plate shearing machine behind leveling before, deposit or transport appearance collision easily in the process, bending causes plate body surface irregularity (not being very high plate body for hardness such as aluminium sheets particularly).In the shear history, see Fig. 1, the length of plate body 3 cuttings is the distance of cutter 1 apart from block 2, because plate body 3 surface irregularities, the length of the actual plate body that obtains 3 is greater than the length L of the plate body of actual needs, makes sheet material can not meet some requirement to sheet material precision assembling higher device.Therefore be necessary to make improvements.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of plate shearing machine, before plate body enters the tool position plate body is flattened, and has guaranteed the precision after plate body is sheared.

The utility model is achieved through the following technical solutions: plate shearing machine, comprise upper die and lower die, cutter is set in patrix when plate is sheared, plate is compressed the hold down gag that prevents the Board position skew with being used for, in counterdie, has the workbench that passes through for plate body, at least one plate is set above described workbench flattens mechanism, described plate flattens mechanism and comprises and be horizontally placed on the crossbeam that described patrix is positioned at described hold down gag front position, below described crossbeam, be set with mount pad, in described mount pad, rotate first pressure roller is set.

The utility model compared with prior art, have following beneficial effect: before plate body enters the tool position, plate body is flattened, guaranteed the precision after plate body is sheared, and when shear, all the time compress plate, prevent the bending injustice that plate produces in shear history.
