Description
Technical field
The utility model relates to the chuck swelling device of the centrifugal drawbench of a kind of ductile iron pipe, belongs to machinery industry technical field.
Background technology
Ductile iron pipe is applied to foggara, and apply rotary die centrifugal casting aborning, the pipe after shaping must be transferred to from mould.
Prior art drawbench adopts frequency converter to add motor and drives, and fixture adopts frame for movement make it strut and reset.Its defect is: frequency converter adds motor and drives in drawing process, weighs, cannot realize quick start and stop, affect operating efficiency because ductile iron pipe workpiece is large; In the application, because fixture struts strength greatly, parts loss is large for the frame for movement of fixture.
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned deficiency existing in prior art, and design is a kind of rational in infrastructure, tube drawing is effective, agrees with the chuck swelling device of the centrifugal drawbench of ductile iron pipe of firm stable between chuck and ductile iron pipe workpiece.
The utility model solves the problems of the technologies described above adopted technical scheme: the chuck swelling device of the centrifugal drawbench of a kind of ductile iron pipe, it is characterized in that: comprise base of the carrier head, clamping bar, four tighting rods, clamping bar is inserted in base of the carrier head, the front end of clamping bar is provided with tension base, four tighting rods are evenly distributed on the outside of clamping bar, end and the base of the carrier head of tighting rod are fixed, and the leading inside of tighting rod is provided with tensioner groove, and tension base snaps in tensioner groove and also coincide mutually; The front end outer side of described tighting rod is provided with fixture block.Chuck swelling device is connected with the pipe drawing device of the centrifugal drawbench of ductile iron pipe, and when chuck swelling device stretches in ductile iron pipe, pipe drawing device promotes clamping bar and advances, and tensioner trench brace is opened by tension base, and four tighting rods tensioner in ductile iron pipe, carries out drawing.
Fixture block described in the utility model is arranged on tighting rod by clamping seat, and clamping seat is fixed on tighting rod by spiral pin, and fixture block is fixed on clamping seat.Fixture block fixation, tensioner is effective.
The material of fixture block described in the utility model is wolfram steel, not easy to wear, increases the service life.
Clamping bar described in the utility model is provided with position restoring claw, and position restoring claw is fixed on the top of clamping bar, and position restoring claw is provided with four elastic arms, and four elastic arms compress the top of four tighting rods respectively.When four tighting rods outwards strut, position restoring claw outwards struts, and drawing completes, and chuck swelling device leaves ductile iron pipe, and four tighting rods reset under the effect of position restoring claw.
Be provided with lubricating sleeve in base of the carrier head described in the utility model, clamping bar, through lubricating sleeve, makes clamping bar slide smooth and easy.
The utility model compared with prior art, has following positive effect: reasonable in design, and the tensioner of chuck swelling device in ductile iron pipe is effective, not easily departs from, not easy to wear, increases work efficiency.
