Abstract
Modified is dabber for return bend, its characterized in that: the ball core of this return bend dabber links to each other with the external screw thread of its internal thread with ball stud to bulb through ball stud links to each other with the II interior bulb shape drums that match with the bulb of connecting axle, and in order to realize universal rotation, connecting axle II links to each other with connecting axle I. Technical scheme reasonable in design is changed into by original chain hookup book and passes through bolted connection by the bulb, by rotating to the return bend direction originally, becomes and to rotate to any direction, finished piece bent pipe portion position is the rounding more, has stopped fold and mar basically, has improved the appearance quality of product greatly, and product quality obviously improves. And install, dismantle, adjust light convenience, and improved production efficiency, life, alleviateed intensity of labour.
Description
Technical field
The invention belongs to minicar parts bend pipe mandrel, relate to the bend pipe mandrel improved.
Background technology
Present bend pipe mandrel, main working parts core, the hemisphere chain assembled of multiple not equal thickness couple, can only rotate to bend pipe direction, service life is short, outward appearance fold and cut, installs, dismantles, adjusts inconvenience, and production efficiency is low.
Summary of the invention
It is an object of the invention to solve the problem that prior art exists, the bend pipe mandrel of a kind of improvement is provided, main working parts core in mandrel assembly, change an overall bulb into, coupled by ball stud, improve the service life of mandrel, and install, dismantle easy and convenient, significantly improve product quality, significantly improve production efficiency.
The technical scheme is that the bend pipe mandrel of improvement, it is characterized in that: the core of this Siphon Mandril is connected with the external screw thread of ball stud with its female thread, and be connected with the bulb-type cylinder mated with bulb in connecting shaft II by the bulb of ball stud, to realize universal rotational, connecting shaft II is connected with connecting shaft I.
The present invention compared with prior art has substantive features and positive effect；
(1) Technical Design is reasonable, original chain couple and change into being connected with connecting shaft II by the bulb of ball stud, by originally rotating to bend pipe direction, becomes energy universal rotational, with the satisfied needs adapting to processing bend pipe or the processing of multistage bend pipe product.
(2) product bend pipe position is more round whole, has substantially stopped fold and cut, substantially increases the quality of product, product quality significantly improves, service life, production efficiency, alleviate labor intensity.

Detailed description of the invention
Now by detailed description of the invention, and the invention will be further described to combine accompanying drawing:
See Fig. 2, Fig. 3, Fig. 4 Fig. 5, Fig. 6, the bend pipe mandrel of improvement, it is characterised in that: core 2-4 of this Siphon Mandril is connected with the bulb-type cylinder mated with bulb in connecting shaft II 2-2 by the bulb of ball stud 2-3, to realize core universal rotational, connecting shaft II 2-2 is connected with connecting shaft I 2-1.
The using method of of the present invention bend pipe mandrel is briefly described below: fill in inside pipe fitting blank by mandrel assembly during use, core center overlaps with product camber center and bending machine roller centre, clamp after accurate positioning, bending machine active force part drives runner to rotate, and completes bend pipe process by set angle；Connecting shaft I2-1 front end is connected by pull bar power section auxiliary with bending machine, and mandrel is exited after terminating from product by bend pipe, takes off product, and bending machine each several part playbacks.
Product bend pipe position is more round whole, has substantially stopped fold and cut, substantially increases the presentation quality of product, and product quality significantly improves.And install, dismantle, adjust easy and convenient, improve production efficiency, alleviate labor intensity；Core with satisfied processing bend pipe or the needs of multistage bend pipe product with universal rotational, can improve the service life of mandrel, use more convenient.
Claims (1)
1. the bend pipe mandrel improved, it is characterized in that: the core of this Siphon Mandril is connected with ball stud external screw thread with its female thread, and be connected with bulb coupling bulb-type cylinder with in connecting shaft II by the bulb of ball stud, to realize universal rotational, connecting shaft II is connected with connecting shaft I.
