Abstract
The utility model relates to the technical field of extruding machines, and particularly relates to a high-strength extruding machine thread bushing. The high-strength extruding machine thread bushing comprises a bushing body, a thread and an inner buckle, wherein the thread and the inner buckle are respectively positioned on the outer wall and inner wall of the bushing body; the cross section of the inner buckle is regularly hexagonal. The regularly hexagonal inner buckle is arranged on the inner wall of the bushing body and sleeved on a corresponding central spindle, so that the stress is balanced, and the anti-twisting capacity of each component of the inner buckle and the central spindle is greatly improved; the integral strength of the bushing body is improved, so that the production efficiency and the product quality are improved.
Description
Technical field
The utility model relates to extruder technology field, especially a kind of high strength extruder thread bush.
Background technology
plastic extruder now is applied to the granulation of plastics widely, painted, mixing, plastic sheeting, plastic material, in the batcher of tubing production and plastic injection equipment, and screw rod is the heart of extruder, its structure is to adopt different thread bush to be combined to be inserted in mandrel, locate by spline between thread bush and mandrel, single spline and notch are thiner, intensity is less, because the working environment of thread bush is more abominable, be in for a long time run up under, in case certain spline or notch damage, whole thread bush is stressed with unbalance, form vicious circle, cause thread bush loosening, thereby affect the performance of whole screw rod, the quality of operating efficiency and product.
The utility model content
Little in order to overcome existing thread bush intensity, affect the deficiency of operating efficiency, the utility model provides a kind of high strength extruder thread bush.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high strength extruder thread bush, comprise body, screw thread and interior button, and screw thread and interior deduction of points are not positioned on the outer wall and inwall of body, and interior button cross section is regular hexagon.
According to another embodiment of the present utility model, comprise that further the axle center of interior button is positioned on the cover body axis.
The beneficial effects of the utility model are, at the inwall of body, orthohexagonal interior button are set, with corresponding mandrel fit, stress equalization not only, and greatly strengthened the anti-twist ability at interior button and mandrel each position, improve the bulk strength of body, and then improved production efficiency and product quality.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. bodies in figure, 2. screw thread, 3. interior button.
The specific embodiment
Be structural representation of the present utility model as Fig. 1, a kind of high strength extruder thread bush comprises body 1, screw thread 2 and interior button 3, and screw thread 2 and interior button 3 lay respectively on the outer wall and inwall of body 1, and interior button 3 cross sections are regular hexagon.The axle center of interior button 3 is positioned on body 1 axis.
Inwall at body 1 arranges orthohexagonal interior button 3, with corresponding mandrel fit, and stress equalization not only, and greatly strengthened the anti-twist ability at interior button 3 and mandrel each position, improve the bulk strength of body 1, and then improved production efficiency and product quality.
Claims (2)
1. a high strength extruder thread bush, comprise body (1), screw thread (2) and interior button (3), and screw thread (2) and interior button (3) lay respectively on the outer wall and inwall of body (1), it is characterized in that, interior button (3) cross section is regular hexagon.
2. high strength extruder thread bush according to claim 1, is characterized in that, the axle center of interior button (3) is positioned on body (1) axis.
