The hydraulic nut has the characteristics of simple structure, low manufacturing cost, long service life, no space occupation, no change of the structure of the hydraulic nut, convenience and reliability in use and high tool changing efficiency.
Description
Technical Field
The utility model relates to a quick detach instrument technical field, more specifically say, relate to a disc shear quick detach instrument of quick detach circle shear hydraulic nut at the disc shear at the tool changing in-process fast.
Background
In the steel rolling and finishing operation of the plate, after a blade of a circle shear shears a steel plate with a certain tonnage, the blade of the circle shear needs to be replaced due to the passivation of the blade. During the replacement of the disc shear blade, the fixed hydraulic nut on the disc shear blade is first removed. After a locking screw in the hydraulic nut is loosened by a pressurizing pump, a screw needs to be installed in a screw hole in the hydraulic screw, and then an iron hammer is used for knocking the screw head to enable the hydraulic nut to rotate clockwise. However, as the locking force still exists between the contact surfaces of the hydraulic nut and the blade and only one stress point is arranged on the hydraulic nut, the stress of the hydraulic nut is not uniform in the rotating process, the hydraulic nut is difficult to disassemble, and the standard time for replacing one blade is 45 minutes, wherein the method and the tool take more than 30 minutes for disassembling the hydraulic nut, so that the tool changing is overtime, the tool changing efficiency is influenced, and the production is directly influenced.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a circle shear quick detach instrument has that the structure is simple and easy, the cost of manufacture is low, long service life, occupation space not, do not change hydraulic nut structure, convenient to use is reliable, efficient characteristics of tool changing.
The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a circle shear quick detach instrument, includes semicircular main part, and main part one end is provided with positioning bolt, and the other end is connected with the handle, and positioning bolt keeps parallel with the handle to all link to each other with the main part with longitudinal connection mode.
In one embodiment, the main body is in a semicircular ring shape with the diameter of 380mm, and comprises an inner circle and an outer circle.
In one embodiment, the positioning bolt penetrates the inner circle from the outer circle.
In one embodiment, the body is 25mm thick.
In one embodiment, the positioning bolt is an M10 high-strength screw with a diameter of 10 mm.
In one embodiment, the handle is 200mm in length.
To sum up, the utility model discloses following beneficial effect has:
the hydraulic nut dismounting device has the advantages that balanced stress points can be produced at two ends of the hydraulic nut in the dismounting process of the disc shear hydraulic nut, and the purpose of quickly dismounting the hydraulic nut is achieved; the hydraulic nut has the characteristics of simple structure, low manufacturing cost, long service life, no space occupation, no change of the structure of the hydraulic nut, convenience and reliability in use and high tool changing efficiency.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic diagram of the present invention.
In the figure: 1-main body, 11-inner circle, 12-outer circle, 2-positioning bolt, 3-handle, 4-hydraulic nut and 41-screw hole.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
It should be noted that all the directional terms such as "upper" and "lower" referred to herein are used with respect to the view of the drawings, and are only for convenience of description, and should not be construed as limiting the technical solution.
Referring to fig. 1, a quick-release tool for a circle shear comprises a semicircular main body 1, wherein the main body 1 is in a semicircular ring shape with the diameter of 380mm and the thickness of 25mm and comprises an inner circle 11 and an outer circle 12, one end of the main body 1 is provided with a positioning bolt 2, and the positioning bolt 2 penetrates into the inner circle 11 from the outer circle 12; the other end is connected with a handle 3, and the positioning bolts 2 are parallel to the handle 3 and are connected with the main body 1 in a longitudinal connection mode.
The positioning bolt 2 is an M10 high-strength screw with the diameter of 10 mm.
The handle 3 is 200mm in length.
Referring to fig. 2, when in actual use, with positioning bolt 2 card in the screw hole 41 on circle shear hydraulic nut 4, circle 11 hugs closely on hydraulic nut 4 in main part 1, strike handle 3 with the hammer, because positioning bolt 2 and handle 3 set up respectively at main part 1 both ends, simultaneously and main part 1 between have fixed relation, consequently when striking handle 3, positioning bolt 2 direction can be to hydraulic nut 4 application of force simultaneously, the simultaneous atress in hydraulic nut 4 both ends, the atress is even, can rotate hydraulic nut 4 fast and dismantle.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
