Background technology
Extruder screw usually uses disconnectable combination, i.e., a variety of rule is set with mandrel according to different needs
The screwing element of lattice, the abrasion condition of visual screw rod changes the screwing element of different parts in use, but spiral shell is changed from mandrel
Texel part is cumbersome, is typically changed using hydraulic test, and hydraulic test investment is big, and cost is high.
The content of the invention
The technical problem to be solved in the present invention is：Overcome deficiency in the prior art, there is provided a kind of inexpensive extruder
Screwing element extracting tool.
The technical solution adopted for the present invention to solve the technical problems is：A kind of extruder screwing element extracting tool, bag
A pair of fixing devices are included, two fixing devices are respectively fixing device A and fixing device B, and fixing device A is arranged on screw thread member to be torn open
On part, fixing device B is oppositely arranged on the screwing element adjacent with screwing element to be torn open,
Fixing device includes annular solid, body and a pair of tight fixed bolts, and annular solid movable set is on screwing element, body
For one end movable set on annular solid, the body other end is fixed with end cap of the movable set on screwing element, body and screw thread
It is provided with a pair of relative and activity gripping blocks between element, gripping block, which is provided with, to be stretched into screwing element thread groove and and thread groove
The contact part that bottom offsets, the pedestal for being fixed on gripping block side being provided between gripping block and annular solid, pedestal is provided with groove,
Stretch into corresponding pedestal groove after the screw that the tight fixed bolt end screw-in is arranged on annular solid and offseted with pedestal again,
The fixing device B is provided with a pair of relative liftout bolts, and liftout bolt end screws in through fixing device B end caps and is arranged on
Offseted after extending again to fixing device A after tapped through hole on fixing device B annular solids with fixing device A annular solids end face.
The beneficial effects of the invention are as follows：A kind of extruder screwing element extracting tool of the present invention, its design structure are simple, real
It is low with, cost.
Brief description of the drawings
The present invention is further described with embodiment below in conjunction with the accompanying drawings.

Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram, only with signal
Mode illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of extruder screwing element extracting tool as shown in Figure 1,2,3, 4, including a pair of fixing devices, two fix dress
Respectively fixing device A1 and fixing device B2 is put, fixing device A1 is arranged on screwing element to be torn open, and fixing device B2 is reverse
It is arranged on the screwing element adjacent with screwing element to be torn open,
Fixing device includes annular solid 3, body 4 and a pair of tight fixed bolts 5, the movable set of annular solid 3 on screwing element,
For one end movable set of body 4 on annular solid 3, the other end of body 4 is fixed with end cap of the movable set on screwing element, body
A pair of relative and activity gripping blocks 6 are provided between 4 and screwing element, gripping block 6 is provided with and stretched into screwing element thread groove
And the contact part 9 to be offseted with thread-groove bottom, one medium-sized 0.8 that the height of contact part 9 should be poorer than screwing element external diameter and bottom footpath
~1.5mm, the pedestal 7 for being fixed on the side of gripping block 6 is provided between gripping block 6 and annular solid 3, pedestal 7 is provided with groove, described
Stretch into the corresponding groove of pedestal 7 after the screw that the end of tight fixed bolt 5 screw-in is arranged on annular solid 3 and offseted with pedestal 7 again,
The fixing device B2 is provided with a pair of relative liftout bolts 8, and the end of liftout bolt 8 screws in through fixing device B2 end caps and set
Put after extending again to fixing device A1 after the tapped through hole on fixing device B2 annular solids 3 with the end of fixing device A1 annular solids 3
Face offsets.
In use, first fixing device B2 is arranged on the screwing element adjacent with screwing element to be torn open, specific steps：a.
Fixing device B2 annular solid 3 is sleeved on the screwing element adjacent with screwing element to be torn open；B. one is placed on screwing element
To gripping block 6, the contact part 9 of gripping block 6 is set to be offseted with screwing element thread-groove bottom；C. upper sleeve body 4 is covered on screwing element, is prevented
Only gripping block 6 comes off；D. adjust tight fixed bolt 5, be passed to pedestal 7 hold out against gripping block 6 can be by fixing device B2 annular
Body 3 is fixed on the screwing element adjacent with screwing element to be torn open.
Then fixing device A1 opposite directions are installed on screwing element to be torn open with same method, fixing device A1 is with consolidating
Determine device B2 in a circumferential direction to stagger 45° angle.
Finally, two liftout bolts 8 are uniformly turned, you can progressively push up fixing device A1 to the left together with screwing element to be torn open
Go out.
The technical concepts and features of above-mentioned embodiment only to illustrate the invention, its object is to allow be familiar with technique
Personage can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to this hair
The equivalent change or modification that bright Spirit Essence is made, it should all cover within the scope of the present invention.
