Description

The workpiece locating mechanism of bender

Technical field

The present invention relates to a kind of bender, particularly relating to a kind of for the workpiece of more than one piece stacking from the bottom to top being carried out bending simultaneously The workpiece locating mechanism of bender.

Background technology

Fin-tube type heat exchanger, as a kind of compact heat exchanger, has a wide range of applications at refrigeration industry.The forming process master of heat exchanger There are following three kinds of forming technologies: pipe bending forming (formation U-tube), mechanical expanding shapes (realizing pipe-wing to connect), tube bank Bending and forming (forms L-type or U-shaped or G type heat exchanger).Tube bank bending and forming is one of critical process of heat exchanger shaping, heat exchanging The performance of device has material impact.

When restraining bending and forming, first heat exchanger is transported on the position of regulation, makes the position wanting bending predetermined against firmly having The bending die (pressure roller) of bending radius, then clamp the heat exchanger being in bending die both sides, make the hold assembly of one or both sides Centered by bending die in rotary moving, then heat exchanger is just squeezed into the angle of bend of regulation along bending die.In particular, Heat exchanger along longitudinal feed bender, then laterally makes predefined curved position put against bending die, bending die under lying status In wanting the top of crooked position, heat exchanger front end is clipped between bending die and clamping die (lower platen), and tail end is (servo-actuated by base plate simultaneously Plate) support, drive actuator, make bending die and clamping die rotate the angle of regulation as requested, clamping die lifting gets up to make heat exchange Device leading portion rotates centered by the center of bending die, thus along bending die molding.

In traditional tube bank bending and forming technique, the method assembled after mostly using single-piece bending.In order to improve working (machining) efficiency, mesh Before take the stacking from the bottom to top of more than one piece heat exchanger more after carry out the technique of direct bending forming.

But the existing bender for the workpiece of more than one piece stacking from the bottom to top being carried out bending simultaneously, on the one hand, U-shaped or G will be realized Type bending need to repeatedly workpiece be reorientated after bending again, process is complicated, and continuity is poor, and production efficiency is low；On the other hand, The workpiece of more than one piece stacking from the bottom to top is when pressure roller brake forming, owing to the bending radius of the bending part of each workpiece is different, after making bending It is difficult to ensure that the end part aligning of each workpiece, affects the serviceability of heat exchanger.

Summary of the invention

The end part aligning of each workpiece after it is an object of the invention to provide a kind of simple in construction and the workpiece bending of more than one piece stacking can being ensured The workpiece locating mechanism of bender.

Above-mentioned purpose is achieved by the following technical solution:

A kind of workpiece locating mechanism of bender, the location before the workpiece of more than one piece stacking from the bottom to top is carried out bending simultaneously, Including the location block face of multiple direction of feed indentations step by step from top to bottom sending into bender along workpiece, each workpiece is resisted against different Position in the direction of feed of workpiece realizing each workpiece on the block face of location.

The present invention compared with prior art has the advantage that bender disclosed by the invention is provided with workpiece locating mechanism so that more than one piece The workpiece of stacking from the bottom to top positions before carrying out bending in the direction of feed of workpiece, the more than one piece workpiece of the stacking behind location Stepped in the most progressively upgrade, that the bending radius of the bending part that so can compensate each workpiece exists difference, is positioned at The bending radius of the bending part of the workpiece on upper strata is certainly less than the bending radius of the bending part of the workpiece being positioned at lower floor, fixed by workpiece Position mechanism makes the end being positioned at the workpiece on upper strata be located relatively at the end indentation certain distance of workpiece of lower floor, and the distance of this indentation is used In the difference of bending radius and the bending radius of the bending part of the workpiece being positioned at lower floor of the bending part compensating the workpiece being positioned at upper strata, After making bending, the end part aligning of each workpiece.
