Abstract
A kind of flexible core-pulling mechanism, be made up of core print (2), core body (1), bearing pin (3), double end pull bar (4), oil cylinder of loosing core (5), it is characterized in that: described core print (2) is connected with core body (1) one end by bearing pin (3), core print (2) rotates around bearing pin (3) and produces small angle oscillation, core body (1) other end is connected with double end pull bar (4) top, and double end pull bar (4) afterbody is connected by coupling assembling (6) with oil cylinder of loosing core (5).The utility model, effectively ensure the accuracy of form and position and the presentation quality in crooked position cross section, structure is simple, easy to operate.
Description
Technical field
The utility model relates to track train door and window part manufacture field, particularly about the flexible core-pulling mechanism of one of frame brake forming processing.
Technical background
Track train door and window frame four angles are these one of circular arc, and produce at present as frame uses four segment type materials difference brake formings to weld through four handling again, operation is loaded down with trivial details; Because circular arc point processes for four times, easy appearance four circular arc angles are inconsistent, precision and production efficiency low, cosmetic look is poor, again because frame is in BENDING PROCESS, shape of peripheral frame internal cavities is because bending by external force, and cavity force dispersion is uneven causes the accuracy of form and position in crooked position cross section and outward appearance unsightly, makes the qualification rate of product lower.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of flexible core-pulling mechanism, core print is connected with core body by bearing pin, core print rotates around bearing pin and produces small angle oscillation, and core body is connected with double end pull bar top, and oil cylinder of loosing core is connected with double end pull bar tail end, core body inserts in the cavity of workpiece, the core print swung is bending along with workpiece, produces small angle oscillation, effectively ensures the accuracy of form and position and the presentation quality in crooked position cross section.
The technical solution of the utility model is achieved in the following ways: a kind of flexible core-pulling mechanism, be made up of core print, core body, bearing pin, double end pull bar, oil cylinder of loosing core, it is characterized in that: described core print is connected with core body one end by bearing pin, core print rotates around bearing pin and produces small angle oscillation, the core body other end is connected with double end pull bar top, and double end pull bar afterbody is connected by coupling assembling with oil cylinder of loosing core.
Respectively there is screw thread at described double end pull bar two ends.
Described core body and core print link place are provided with U-lag, and core print inserts in U-lag, passes through pinned connection.
The utility model, effectively ensure the accuracy of form and position and the presentation quality in crooked position cross section, structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that core print is connected side schematic view with core body.
In figure: 1 be core body, 2 be core print, 3 be bearing pin, 4 for double end pull bar, 5 be oil cylinder of loosing core, 6 for coupling assembling.
Detailed description of the invention
Known by Fig. 1, Fig. 2, a kind of flexible core-pulling mechanism, be made up of core print 2, core body 1, bearing pin 3, double end pull bar 4, oil cylinder 5 of loosing core, core print 2 is connected with core body 1 by bearing pin 3, core print 2 rotates around bearing pin 3 in core body 1, produce small angle oscillation, core body 1 afterbody is connected with double end pull bar 4, and double end pull bar 4 is connected by coupling assembling 6 with oil cylinder 5 of loosing core.Double end pull bar 4 is by carbon steel cold-drawn material, and through two ends, hitch forms; During operation, oil cylinder 5 of loosing core stretches out, the core print 2 on core body 1 is made to be in operating position, and ensure that position immobilizes under the effect of oil cylinder 5 of loosing core, along with the bending generation small angle oscillation of workpiece, the accuracy of form and position and the presentation quality in crooked position cross section can be effectively ensured with the core body 1 swinging core print 2; After segmental arc bending machining terminates, oil cylinder 5 of loosing core shrinks, by core print 2 from operating position longitudinally post-tensioning.
