Description
Technical field
The present invention relates to the material toggling mechanism of a kind 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 of heat exchanger mainly has following three kinds of forming technologies: pipe bending forming (formation U-tube), mechanical expanding shapes (realizing pipe-wing to connect), and tube bank bending and forming (forms L-type 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 bending against the bending die (transfer roller) firmly with predetermined bending radius, then the heat exchanger being in bending die both sides is clamped, the hold assembly making one or both sides is in rotary moving centered by bending die, and then heat exchanger is just squeezed into the angle of bend of regulation along bending die.In particular, heat exchanger under lying status along longitudinal feed bender, then laterally make predefined curved position against bending die, bending die is placed in the top wanting crooked position, heat exchanger front end is clipped between bending die and clamping die (lower platen), tail end is supported 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 along bending die molding.
In traditional tube bank bending and forming technique, mostly using and manually after the input of bender main frame is delivered in the bending die in bender main frame, the heat exchanger until bending is curved molding, the work efficiency of this material-uploading style is relatively low and labor intensity is big.
Summary of the invention
It is an object of the invention to provide the material toggling mechanism of a kind of simple in construction, bender reasonable in design.
Above-mentioned purpose is achieved by the following technical solution:
A kind of material toggling mechanism of bender, including: material loading platform, treat bending workpieces for supporting；Material toggling support；Material toggling guiding mechanism, is located between material loading platform and material toggling support for guiding material toggling support to translate；Material toggling drive mechanism, is located between material loading platform and material toggling support for ordering about the translation of material toggling support；Swing span, is hubbed on material toggling support and follows the translation of material toggling support；Swing driving mechanism, is located between material toggling support and swing span and orders about swing span and dodge position and one and push and swing between position；Push piece, is located on swing span and follows swing span and swing, swing span can make when swinging push piece away from or near material loading platform；Swing span is in when dodging position, push piece away from material loading platform so that push piece translation time avoid treating bending workpieces；When swing span is in propelling movement position, push piece near material loading platform so that push piece can be kept out treat that bending workpieces promotion treat that bending workpieces translates when translation.
The present invention compared with prior art has the advantage that material toggling mechanism disclosed by the invention simple in construction, it is possible to realizes Automatic Conveying and treats that bending workpieces is to reduce labor intensity and to improve work efficiency.
