Description
Technical field
The utility model relates to large pitch low pressure contracting high speed and precision bolt specials, belong to screw technique field.
Background technique
It is chiefly used in plastic molding equipment, such as plastic section extruding machine, injection molding machine, screw rod and machine barrel are plastic molding equipments
Core component is the part for heating extrusion plasticizing, is the core of plastics machinery, the spiral shell rib on the screw body outer wall of the prior art is all
It is fixed spiral shell rib, the spiral shell rib of various height can not be adjusted to, the spiral shell rib structure on the screw rod wall made is excessively single, in order to solve
Above-mentioned difficulties need to develop the large pitch low pressure contracting high speed and precision bolt special of a spiral shell rib for being adjusted to various height.
Summary of the invention
The purpose of the utility model is to provide large pitch low pressure contracting high speed and precision bolt specials.
Problem to be solved in the utility model is that the spiral shell rib on the screw body outer wall of the prior art is all fixed spiral shell rib, nothing
Method is adjusted to the problem of spiral shell rib of various height.
To realize the purpose of this utility model, the technical solution adopted in the utility model is:
Large pitch low pressure contracting high speed and precision bolt special, including screw head, screw body, perpendicular rib, hush panel, screw rod set, spiral shell
Rib and arc-shaped cavity, the screw head are arranged in screw body, and screw body outer wall is equipped with multiple perpendicular ribs, and screw rod set is set in screw body
Outside, screw rod set is externally provided with the spiral shell rib to spiral from top to bottom, and screw rod covers two sides up and down and is respectively provided with hush panel, is equipped in hush panel multiple
The arc-shaped cavity being mutually matched with perpendicular rib, perpendicular rib are contained in arc-shaped cavity, and arc-shaped cavity and perpendicular rib correspond.
Perpendicular rib and screw body are accommodated in the inner by the screw rod set.
The internal diameter of the screw rod set is greater than the distance between symmetrical two perpendicular ribs.
The screw rod set is made of manganese-titanium material.
The screw slenderness ratio is 22:1.
It is big that the screw rod covers upper spiral shell rib lead.
The hush panel is located at outside screw body.
The utility model has the advantages that: arc-shaped cavity, which is bonded, erects rib, and the size of the size of arc-shaped cavity and perpendicular rib is mutually matched, on
Lower mobile screw set, moves up and down spiral shell rib with screw rod set, adjusts position of the spiral shell rib on screw body outer wall, is adjusted to various
The spiral shell rib of height can move up and down hush panel since arc-shaped cavity and perpendicular rib are not fixed and welded together, and make the arc of hush panel
Shape chamber is moved up and down along perpendicular rib, and hush panel is moved to the upper and lower ends of screw rod set, and hush panel is welded on screw rod set
Together, while by the arc-shaped cavity position of hush panel with perpendicular rib, screw body weld together, realize hush panel and perpendicular rib, screw body
Weld together, screw rod set is fixed on outside screw body；Screw body draw ratio is 22:1, can prevent plastics from degrading in advance；Screw rod
Spiral shell rib lead is big on set, can improve mixing.

In figure: 1, screw head 2, screw body 3, perpendicular rib 4, hush panel 5, screw rod set 6, spiral shell rib 7,
Arc-shaped cavity.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
The utility model large pitch low pressure contracting high speed and precision bolt special, including screw head 1, screw body 2, perpendicular rib 3, sealing
Plate 4, screw rod set 5, spiral shell rib 6 and arc-shaped cavity 7, the screw head 1 are located in screw body 2, and 2 outer wall of screw body is equipped with multiple perpendicular ribs 3,
Screw head 1, screw body 2 and perpendicular rib 3 are integrated made of cutting, and screw rod set 5 is set in outside screw body 2, and screw rod set 5 is externally provided with certainly
The spiral shell rib 6 to spiral under above, spiral shell rib 6 and screw rod set 5 are integrated made of cutting, and screw rod covers about 5 two sides and is respectively provided with hush panel
4, equipped with multiple arc-shaped cavities 7 being mutually matched with perpendicular rib 3 in hush panel 4, perpendicular rib 3 is contained in arc-shaped cavity 7, arc-shaped cavity 7 and perpendicular
Rib 3 corresponds.
Perpendicular rib 3 and screw body 2 are accommodated in the inner by the screw rod set 5.
The internal diameter of screw rod set 5 is greater than the distance between symmetrical two perpendicular ribs 3, the internal diameter of screw rod set 5 and perpendicular
Rib 3 and screw body 2 are separated from each other.
The utility model application method: arc-shaped cavity 7, which is bonded, erects rib 3, and size mutual of the size of arc-shaped cavity 7 and perpendicular rib 3
Match, move up and down screw rod set 5, move up and down spiral shell rib 6 with screw rod set 5, adjusts position of the spiral shell rib 6 on 2 outer wall of screw body,
Since arc-shaped cavity 7 and perpendicular rib 3 are not fixed and welded together, hush panel 4 can be moved up and down, makes 7 edge of arc-shaped cavity of hush panel 4
Perpendicular rib 3 move up and down, hush panel 4 is moved to the upper and lower ends of screw rod set 5, hush panel 45 is welded on one with screw rod set
It rises, while 7 position of the arc-shaped cavity of hush panel 4 and perpendicular rib 3, screw body 2 being welded together, realize hush panel 4 and perpendicular rib 3, spiral shell
The body of rod 2 welds together, and screw rod set 5 is fixed on outside screw body 2；2 draw ratio of screw body is 22:1, can prevent plastics from dropping in advance
Solution；Spiral shell rib lead on screw rod set 5 is big, can improve mixing.
