Abstract
The invention relates to a workpiece locating mechanism of a bending machine. The workpiece locating mechanism of the bending machine is used for locating multiple workpieces stacked from bottom to top before bending and comprises multiple locating stop faces which retract step by step from top to bottom in the direction of feeding the workpieces into the bending machine. The workpieces abut against the different locating stop faces so that the workpieces can be located in the feeding direction. By the adoption of the workpiece locating mechanism of the bending machine, the workpieces stacked from bottom to top can be located in the feeding direction before the workpieces are bent, the located and stacked workpieces are in the step shape that the workpieces gradually rise from bottom to top, in this way, the differences between the bending radiuses at the bent positions of the workpieces can be compensated for, the end of each workpiece located on the upper layer retracts by a certain distance relative to the end of the corresponding workpiece located on the lower layer, the retraction distance is used for compensating for the difference between the bending radius at the bending position of each workpiece located on the upper layer and the bending radius at the bending position of the corresponding workpiece located on the lower layer, and therefore the ends of the workpieces are aligned after the workpieces are bent.
Description
Technical field
The present invention relates to a kind of bender, particularly relate to a kind of workpiece locating mechanism carrying out the bender of bending simultaneously for the workpiece stacked from the bottom to top to more than one piece.
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 of heat exchanger mainly contains following three kinds of forming technologies: pipe bending forming (formation U-tube), and mechanical expanding is shaped (realizing pipe-wing to connect), tube bank bending and forming (forming L-type or U-shaped or G type heat exchanger).Tube bank bending and forming is one of critical process of heat exchanger shaping, and the performance of heat exchanger has material impact.
When restraining bending and forming, first heat exchanger is transported on the position of regulation, make the position wanting to bend near the bending die (pressure roller) firmly with predetermined bending radius, then the heat exchanger being in bending die both sides is clamped, make the hold assembly of one or both sides in rotary moving centered by bending die, so heat exchanger is just squeezed into the angle of bend of regulation along bending die.In particular, heat exchanger longitudinally sends bender under lying status, then laterally make predefined curved position near bending die, bending die is placed in the top of wanting crooked position, heat exchanger front end is clipped between bending die and clamping die (lower platen), tail end supports by base plate (movable head) simultaneously, drive actuator, bending die and clamping die is made to rotate the angle of regulation as requested, clamping die lifting gets up to make heat exchanger leading portion to rotate centered by the center of bending die, thus shaping along bending die.
In traditional tube bank bending and forming technique, single-piece is mostly adopted to bend the method for rear assembling.In order to improve working (machining) efficiency, after taking at present more than one piece heat exchanger stacked from the bottom to top, carry out the technique of direct bending forming more.
But the existing bender carrying out simultaneously bending for the workpiece stacked from the bottom to top to more than one piece, on the one hand, realize U-shaped or G type bending need repeatedly reorientate workpiece after bending again, process is complicated, and continuity is poor, and production efficiency is low; On the other hand, the stacked from the bottom to top workpiece of more than one piece, when pressure roller brake forming, because the bending radius of the bending part of each workpiece is different, is difficult to the end part aligning ensureing each workpiece after making bending, affects the serviceability of heat exchanger.
Summary of the invention
The object of the present invention is to provide a kind of structure simple and workpiece locating mechanism that the is bender of the end part aligning of each workpiece after the workpiece bending that more than one piece is stacked can be ensured.
Above-mentioned purpose is achieved by the following technical solution:
A kind of workpiece locating mechanism of bender, the location before bending is simultaneously carried out for the workpiece stacked from the bottom to top to more than one piece, comprise multiple location block face sending into the direction of feed indentation step by step of bender from top to bottom along workpiece, each workpiece is resisted against on different location block faces and locates in the direction of feed of workpiece to realize each workpiece.
The present invention compared with prior art tool has the following advantages: bender disclosed by the invention is provided with workpiece locating mechanism and positions in the direction of feed of workpiece before carrying out bending to make more than one piece workpiece stacked from the bottom to top, stacked more than one piece workpiece behind location is stepped in what progressively upgrade from the bottom to top, the difference that the bending radius that can compensate the bending part of each workpiece like this exists, the bending radius being positioned at the bending part of the workpiece on upper strata must be less than the bending radius of the bending part of the workpiece being positioned at lower floor, made the end of the workpiece being positioned at upper strata relatively be positioned at the end indentation certain distance of the workpiece of lower floor by workpiece locating mechanism, the distance of this indentation is for the bending radius that compensates the bending part of the workpiece being positioned at upper strata and the difference of bending radius of bending part of workpiece being positioned at lower floor, after making bending, the end part aligning of each workpiece.
