Abstract

The utility model discloses a double-machine linking bending machine, which belongs to the technical field of bending machines. The double-machine linking bending machine comprises a first bending machine and a second bending machine, wherein each of the bending machines is provided with a workbench; the workbenches are fixed with lower moulds; both ends of each of the bending machines are provided with side plates; the workbench and the lower mould of the first bending machine are extended out of one of the side plates, are extended to the inner side of the side plate of the second bending machine and are spliced with the workbench and the lower mould of the second bending machine. Because the end surfaces of the workbench and the lower mould are finish machining surfaces, splicing gaps of the splicing points of the workbenches and the lower moulds of the first bending machine and the second bending machine are very small and below 1MM. During double-machine linking operations, plate materials at the splicing gaps of the lower moulds of the two bending machines have the advantages of high bending precision and no shaped transition zone. The utility model is particularly suitable for the plate materials, wherein the bending lengths of the plate materials are longer than the width of one set of the bending machine.

Description

A kind of dual-machine linkage bender

Technical field

The utility model relates to a kind of bender, particularly the bender of dual-machine linkage.

Background technology

In the prior art, the length of bending plate is often greater than the width of separate unit bender, be this overlength plate of bending, need carry out the dual-machine linkage operation, being about to two benders is stitched together, and make its synchronous working, this bender can be referred to as the dual-machine linkage bender, mainly comprise first bender and second bender, be equipped with workbench on each bender, be fixed with counterdie on the described workbench, the two ends of each bender are provided with side plate, and the two ends of workbench and counterdie are all concordant with the corresponding side plate outside, because side plate is the roughing part, when two-shipper is stitched together, have the gap inevitably between first bender and second bender, making workbench on first bender and the workbench on the counterdie and second bender and the gap between the counterdie is 3-5mm, when dual-machine linkage bending plate, seam crossing at counterdie can form a discontinuous folding line, causes the plate bending precision poor.

The utility model content

The purpose of this utility model provides a kind of dual-machine linkage bender, makes bender splicing gap little, and plate is at the seam crossing bending precision height of two benders.

The purpose of this utility model is achieved in that a kind of dual-machine linkage bender, comprise first bender and second bender, be equipped with workbench on each bender, be fixed with counterdie on the described workbench, the two ends of each bender are provided with side plate, workbench on described first bender and counterdie stretch out in outside the side side plate, and extend to the side plate inboard of second bender, splice mutually with the workbench and the counterdie of second bender.

In the utility model, because the end face of workbench and counterdie is a polished surface, therefore the seam of splicing place is very little mutually can to make the workbench of first bender and second bender and counterdie, below 1mm, during dual-machine linkage work, plate does not have special-shaped transition region at the counterdie seam crossing bending precision height of two benders; The utility model is particularly suitable for the plate of bending length greater than separate unit bender width.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is that the A-A of Fig. 1 is to the partial structurtes schematic diagram;

Wherein, 1 splicing seams, 2 first benders, 3 side plates, 4 second benders, 5,5 ' workbench, 6,6 ' counterdie.

The specific embodiment

As figure, be the dual-machine linkage bender, comprise first bender 2 and second bender 4, be equipped with workbench on each bender, be fixed with counterdie on the workbench, workbench 5 and counterdie 6 that the two ends of each bender are provided with on side plate 3, the first benders 2 stretch out in outside the side side plate 3, and extend to the side plate inboard of second bender 4, with workbench 5 on second bender 4 ' and counterdie 6 ' splicing mutually; Because the end face of workbench and counterdie is a polished surface, therefore splicing seams 1 gap of splicing place is very little mutually can to make the workbench of first bender 2 and second bender 4 and counterdie, below 1mm, during dual-machine linkage work, plate does not have special-shaped transition region at the counterdie seam crossing bending precision height of two benders.

Claims

1, a kind of dual-machine linkage bender, comprise first bender and second bender, be equipped with workbench on each bender, be fixed with counterdie on the described workbench, the two ends of each bender are provided with side plate, it is characterized in that: workbench on described first bender and counterdie stretch out in outside the side side plate, and extend to the side plate inboard of second bender, splice mutually with the workbench and the counterdie of second bender.
