Abstract
A steel material die-forging shackle includes a shackle body (1) which is provided with a bend arc section. The cross section of the bend arc section of the shackle body (1) takes the shape of an 'I'; the lower surface (2) of the 'I'-shaped shackle body (1) is the internally concave arc surface. As the cross section of the bend arc section of the shackle takes the shape of an 'I', the bearing capability of the shackle body can be largely improved compared with the round-shaped cross section or the ellipse-shaped cross section with the same material. As the lower surface of the 'I'-shaped shackle body is the arc surface which is internally concave, the contact area with the rigging is large. As the traditional round cross section is replaced with the 'I'-shaped cross section, the contact area between the rigging and the shackle body can be increased by 60% or so, thus the abrasion, scraping damage or pressing damage to the surface of the rigging is relived, and the service life of the relevant parts is improved; compared with the traditional shackle, as the curvature radius of the bend of the rigging is enlarged, the bearing capability of the rigging can be improved by 15%. The utility model aims at providing a steel material die-forging shackle which has large bearing capability, long service life and can relieve the abrasion of the rigging.
Description
Technical field
The utility model relates to a kind of steel drop forged shackle.
Background technique
Along with the high speed development of China's hoisting and hanging industry, quickened the speed of the update of China's hoisting and hanging rigging, the lifting rigging has also been proposed more and more higher requirement.The button diameter of section of the shackle of using mostly is circular or oval at present, and the area of contact between button and rigging when stressed (chain rigging or the rope rig) collar is less, and the bending radius of rigging is little, causes rigging more fragile.
The model utility content
The purpose of this utility model is to provide a kind of bearing capacity big, and long service life can alleviate the steel drop forged shackle to the rigging wearing and tearing.
Steel drop forged shackle of the present utility model comprises the button with curved arc section, and the cross section of described button curved arc section is I-shaped, and the lower surface of I-shaped button is respectively the arc shaped surface towards internal projection.
Steel drop forged shackle of the present utility model, the upper surface of wherein said I-shaped button are the arc shaped surface towards outer lug.
Steel drop forged shackle of the present utility model, wherein be positioned at described I-shaped button curved arc section middle part about two sides have stiffening rib.
Steel drop forged shackle of the present utility model, the width of wherein said I-shaped button upper surface is less than the width of lower surface.
The advantage and the good effect of steel drop forged shackle of the present utility model are: because the cross section of button curved arc section is I-shaped, under equal materials situation, compare with circular or oval-shaped cross section, the bearing capacity of button can greatly improve, test shows, under the situation that does not increase the shackle deadweight, can improve 20% volume loading capability.Because of the lower surface of I-shaped button is a arc shaped surface towards internal projection, so itself and rigging surface of contact are bigger, because traditional circular cross-section is changed over I-shaped cross section, can make the area of contact of rigging and button increase about 60%, thereby can alleviate wearing and tearing or scuffing that the rigging surface is caused, weigh wounded, improve the working life of related components; Compare with traditional shackle,, thereby can improve the bearing capacity of rigging 15% because the radius of curvature of rigging bending increases.
Other details of the utility model steel drop forged shackle and characteristics can just can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings.
Description of drawings
Fig. 1 is the plan view of structural representation of the novel steel drop forged shackle of this practicality;
Fig. 2 is the side view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the utility model steel drop forged shackle comprises having curved arc section button 1, and the cross section of button 1 curved arc section is I-shaped, the lower surface 2 of I-shaped button 1 is respectively the arc shaped surface towards internal projection, and the upper surface 3 of I-shaped button 1 is the arc shaped surface towards outer lug.Be positioned at I-shaped button 1 curved arc section middle part about two sides have stiffening rib 4, the width of I-shaped button 1 upper surface 3 is less than the width of lower surface 2.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design proposal prerequisite; common engineers and technicians make the technical solution of the utility model in related domain various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
Claims (4)
1. the steel drop forged shackle comprises the button (1) with curved arc section, it is characterized in that the cross section of described button (1) curved arc section is I-shaped, and the lower surface (2) of I-shaped button (1) is respectively the arc shaped surface towards internal projection.
2. steel drop forged shackle according to claim 1 is characterized in that the upper surface (3) of described I-shaped button (1) is the arc shaped surface towards outer lug.
3. steel drop forged shackle according to claim 2, it is characterized in that being positioned at described I-shaped button (1) curved arc section middle part about two sides have stiffening rib (4).
4. steel drop forged shackle according to claim 3 is characterized in that the width of the width of described I-shaped button (1) upper surface (3) less than lower surface (2).
