Abstract
The utility model aims at providing an extruding machine screw rod dismounting device to solution screw rod in the screw rod operation is changed to the extruding machine is dismantled and once to be accomplished, loses time, consumes the problem of manpower. The device includes nut and the screw mandrel who is connected with the nut, and screw mandrel sets up flat housing with the one end that the nut is connected, and the flat housing terminal surface is equipped with the flat housing retaining ring, and screw mandrel keeps away from a end screw thread connection screw mandrel nut of nut, and screw mandrel nut tail end periphery sets up recess, screw mandrel nut tail end screw thread connection screw mandrel 1, screw mandrel 3 between each screw mandrel 1. The utility model provides an extruding machine change in the screw rod operation screw rod and dismantle and once to accomplish, lose time, consume the problem of manpower, the square nut is fixed and on the silk, is cooperated a plurality of transmission and square nuts that are formed by connecting transmission lead screw and transmission screw -nut the screw rod is torn open to the extruding machine reducing gear box outside again to it dismantles the extruding machine screw rod to set up cubic recess convenient to use spanner on transmission screw -nut.
Description
Technical field
This utility model belongs to cable production field and in particular to a kind of extruder screw provision for disengagement.
Background technology
The large-scale screw diameter of extruding machine typically in more than 150mm, such as150、200、250 extruding machines, extruding machine is big
Type screw rod, mainly for the production of heavy in section wire cable insulating layer and restrictive coating, for adapting to the needs of different plastic processings, needs
Change the screw rod of different types, existing screw bolt detachment tool can only make screw rod depart from reduction box, needs manually by screw rod slave
Take out in cylinder, waste time and energy.
Utility model content
The purpose of this utility model is to provide a kind of extruder screw provision for disengagement, to solve to change screw rod work in extruding machine
In industry, screw rod dismounting cannot once complete, and loses time, the problem of labor intensive.
For solving the above problems, the technical solution adopted in the utility model is：
A kind of extruder screw provision for disengagement, the fixing screw mandrel be connected including nut and with nut, fixing screw mandrel and nut
One end setting plane bearing connecting, plane bearing end face is provided with plane bearing back-up ring, and fixing screw mandrel is away from one end spiral shell of nut
Stricture of vagina is connected feed screw nut, fixing feed screw nut's tail end periphery setting groove, and fixing feed screw nut's threads connect transmission
Device, actuating device includes drive lead screw and drive lead screw nut, and drive lead screw and drive lead screw nut pass through drive lead screw tail
End is threaded, and the periphery at drive lead screw nut two ends is respectively provided with groove, at least provided with two groups of actuating devices, each actuating device it
Between join end to end.
In order to this utility model is better achieved, fixing screw mandrel end setting screw fixed pan bearing and plane bearing keep off
Circle.
In order to this utility model is better achieved, groove is cubic groove.
In order to this utility model is better achieved, nut is sides nut.
This utility model, compared to prior art, has the advantages that：Sides nut of the present utility model is fixed on
Extruding machine reduction box is torn open on the outer silk of screw rod, then by multiple actuating devices being formed by connecting by drive lead screw and drive lead screw nut with
Sides nut coordinates, and the cubic groove of setting spanner easy to use is dismantled to extruder screw on drive lead screw nut.
Brief description
Fig. 1 is structural representation of the present utility model.
Reference implication is as follows：1st, nut；2nd, fixing screw mandrel；3rd, plane bearing；4th, plane bearing back-up ring；5th, fixing silk
Stem nut；6th, groove；7th, actuating device；8th, drive lead screw；9th, drive lead screw nut；10th, screw.
Specific embodiment
A kind of extruder screw provision for disengagement as shown in Figure 1, the fixing screw mandrel 2 be connected including nut 1 and with nut 1, spiral shell
Female 1 is sides nut, one end setting plane bearing 3 that fixing screw mandrel 2 is connected with nut 1, and plane bearing 3 end face is provided with plane axis
Hold back-up ring 4, fixing screw mandrel 2 end arranges screw 10 fixed pan bearing 3 and plane bearing back-up ring 4, fixing screw mandrel 2 is away from nut
1 threaded one end is connected feed screw nut 5, fixing feed screw nut 5 tail end periphery setting groove 6, and groove 6 is cubic groove,
Fixing feed screw nut 5 threads connect actuating device 7, and actuating device 7 includes drive lead screw 8 and drive lead screw nut 9, transmission
Screw mandrel 8 and drive lead screw nut 9 pass through drive lead screw 8 threads and connect, and the periphery at drive lead screw nut 9 two ends is respectively provided with recessed
Groove 6, at least provided with two groups of actuating devices 7, joins end to end between each actuating device 7.
Before dismounting operation, rotate sides nut 1 using adjustable wrench and be connected with the outer silk of extruding machine reduction box screw rod,
So that the plane bearing back-up ring 4 of fixing screw mandrel 2 end is connected with screw rod end face, adjustable wrench is stuck in the four of fixing feed screw nut 5
Square groove 6 is interior and rotates, and so that the plane bearing back-up ring 4 of fixing screw mandrel 2 end, plane bearing 3 is in close contact with screw rod end face, root
Need according to operation, several actuating device 7 sequentially turns being made up of drive lead screw 8 and drive lead screw nut 9 are carried out head and the tail and connects
Connect, extruder screw is ejected from machine barrel.
