Abstract
The utility model provides a kind of drawing head, and drawing head structure comprises: traction base, stretching arm, stretching mouth, stretching arm sleeve and support spring; Stretching arm sleeve weld is on traction base, and the base portion of stretching arm is placed in stretching arm sleeve, and one end of stretching arm is welded with stretching mouth, the other end is furnished with bolt and nut, and two ends are overlapped respectively support spring.This drawing head employing support spring and stretching arm that can be movable, reduce drawing head and be pulled the rigid damage between machinery; Use the cast steel strengthening version, make drawing head hard wear resistant more, add the service life of drawing head; The stretching arm other end has screw thread, is furnished with bolt and nut, even if drawing head damages, be also convenient to replacing, time saving and energy saving, economize on resources.
Description
Technical field
The utility model relates to manufacturing equipment field, is specifically related to manufacturing and designing of drawing head in manufacturing equipment.
Background technology
The stretching arm of the drawing head generally used at present is directly welded on traction base, drawing head and to be pulled between machinery constantly friction and to collide, and easily make drawing head rupture, and after rupturing, whole drawing head just scrapped, and is unfavorable for energy-conserving and environment-protective.Existing drawing head is all irony, easily corrodes, and fracture, service life is short.
Utility model content
In order to overcome the defect of prior art, main purpose of the present utility model is to provide a kind of long service life, and it is convenient to change, the drawing head economized on resources.
The utility model provides a kind of drawing head device, it is characterized in that, comprises traction base, stretching arm and stretching arm sleeve.Traction base corner is porose, is fixed by bolt and nut, and stretching arm sleeve weld is on traction base.
This drawing head is formed by strengthening an edition cast steel, and hard wear resistant is more not fragile.
The base portion of stretching arm is placed in stretching arm sleeve, and leaves gap with the inwall of stretching arm sleeve, and the two ends of stretching arm reach outside stretching arm sleeve.
One end of stretching arm has screw thread, and is furnished with bolt and nut, and the diameter of nut is greater than the diameter of stretching arm sleeve, the other end is welded with stretching mouth, even if so drawing head in the case of damages, has also been convenient to replacing, time saving and energy saving, economizes on resources.Two gap locations at stretching arm two ends and stretching arm sleeve two ends all overlap respectively and have support spring, thus reduce the friction between stretching arm and stretching arm sleeve, increase service life.
The beneficial effects of the utility model: this drawing head adopts stretching arm and support spring that can be movable, reduce in drawing head and the rigid damage that is pulled between machinery; The reinforcement version cast steel hard wear resistant more used, improves the service life of drawing head; The stretching arm other end has screw thread, is furnished with bolt and nut, even if drawing head is in the case of damages, be also convenient to replacing, time saving and energy saving, economize on resources.
Accompanying drawing explanation
Figure 1 shows that this uses novel structural representation.
Detailed description of the invention
Hereafter will describe embodiment of the present utility model by reference to the accompanying drawings in detail.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they can mutually be combined thus be reached better technique effect.In the accompanying drawing of following embodiment, the identical label that each accompanying drawing occurs represents identical feature or parts, can be applicable in different embodiment.
Figure 1 shows that this uses novel structural representation.
The utility model comprises traction base 1, stretching arm 2 and stretching arm sleeve 3.Traction base 1 four jiaos is porose, is fixed by bolt, and stretching arm sleeve 3 is welded on traction base 1.
This drawing head is formed by strengthening an edition cast steel, and hard wear resistant is more not fragile, adds service life.
The base portion of stretching arm 2 is placed in stretching arm sleeve 3, and leaves gap with the inwall of stretching arm sleeve 3, and the two ends of stretching arm 2 reach outside stretching arm sleeve 3, so stretching arm 2 can be freely movable in stretching arm sleeve 3.
One end of stretching arm 2 has screw thread, and is furnished with bolt and nut 4, and the diameter of nut 4 is greater than the diameter of stretching arm sleeve 3, even if so stretching arm fracture damage, be also convenient to replacing, time saving and energy saving, economize on resources; The other end of stretching arm 2 is welded with stretching mouth 6, is connected with trailed machinery; Two gap locations at stretching arm 2 two ends and flexibility 3 two ends overlap respectively and have a joint support spring 5, when stretching arm 2 under tension activity, support spring 5 can reduce friction between stretching arm 2 and stretching arm sleeve 3 and collision, also can cushion drawing head and the collision be pulled between machinery and reduce to rub.
Although given embodiments more of the present utility model, it will be understood by those of skill in the art that when not departing from the utility model spirit herein, can change embodiment herein.Above-described embodiment is exemplary, should using embodiment herein as the restriction of the utility model interest field.
Claims (3)
1. a drawing head, is characterized in that, comprises traction base, stretching arm, stretching arm sleeve, nut, support spring and stretching mouth; Described stretching arm sleeve weld is on described traction base, the base portion of described stretching arm is placed in described stretching arm sleeve, and leave gap with the inwall of described stretching arm sleeve, the two ends of described stretching arm reach outside described stretching arm sleeve, the two ends of described stretching arm are all overlapped respectively and are had described support spring, one end of described stretching arm is welded with described stretching mouth, the described stretching arm other end has screw thread, and be furnished with bolt and described nut, and the diameter of described nut is greater than the diameter of described stretching arm sleeve.
