Description
Technical Field
The utility model relates to the technical field of connecting pieces, in particular to a multi-wire rope section blank.
Background
The wire rope knot generally comprises a connection and a lifting lug. The plurality of wire rope knuckles are, as the name implies, the knuckles connecting the plurality of wire ropes. The plurality of wire rope segment blanks are in a form prior to connection to the wire rope. At present, the fixing mode of the steel wire rope section blanks and the steel wire ropes adopts a casting process, and the process is mature in the industry. However, the casting requires molten alloy water, and has high energy consumption and unstable product quality. Thus, it has been proposed by those skilled in the art to connect a plurality of wire ropes to a socket blank by crimping.
At present, a plurality of wire rope knuckle blanks comprise a connecting part and lifting lugs, and the side wall of the connecting part is a smooth plane. When the wire rope segment blank is pressed against the wire rope, the material of the wire rope segment blank flows, and a resultant force of pressure is applied from the width side of the segment blank according to the property to which the metal material flows, the flow direction of the material is the direction of both sides in the thickness direction, the resultant force of pressure is applied from both sides in the thickness direction, and the flow direction of the material is the direction of both sides in the width direction. It is known in the cold pressing industry that a mold is required to ensure that the pressed product meets the dimensional requirements during pressing, and as the side wall of the connecting part is a smooth plane, the material flows to two sides in the thickness direction or two sides in the width direction without yielding, so that the extrusion force of the material on the mold is large, and the mold is damaged.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a plurality of steel wire rope section blanks, and the blanks are not easy to damage a die.
In order to solve the problems, the following technical scheme is provided:
The multi-wire rope section blank comprises a connecting part which is fixedly connected with a wire rope, and one end of the connecting part is provided with a lifting lug which is connected with a lifting appliance. The connecting part is characterized in that grooves are formed in two corresponding side faces in the width or thickness direction of the connecting part, and the height of each groove is 0.5 time greater than that of the connecting part.
Wherein the diameter of the steel wire rope is 10mm-20mm, and the length of the connecting part is 4-9 times of the diameter of the steel wire rope; the width of the groove is 10-45mm, and the depth is 2-4.5mm.
The grooves are V-shaped grooves or R-shaped grooves.
The groove is positioned in the middle of the side face of the connecting part.
By adopting the scheme, the method has the following advantages:
Because the grooves are arranged on the two corresponding side surfaces of the connecting part of the plurality of steel wire rope knuckle blanks in the width or thickness direction, the height of the grooves is 0.5 time greater than that of the connecting part. When the grooves are formed on both sides in the width direction of the connecting portion, pressure is applied to the thickness side of the connecting portion when the grooves are pressed; when the grooves are formed on both sides in the thickness direction of the connecting portion, pressure is applied to the width side of the connecting portion when the grooves are pressed, so that the material can flow into the grooves, the pressing force of the material against the die is made small, and excessive material pressing the die is avoided. Moreover, the height of the groove is 0.5 times greater than the height of the connecting part, so that when enough space is reserved for accommodating a plurality of steel wire ropes to be pressed, the flowing amount of materials in the connecting part is ensured, and the die is not damaged by extrusion.
Drawings
Fig. 1 is a schematic view of the structure of a plurality of wire rope knuckle blanks of the present utility model.
Detailed Description
The utility model is described in further detail below with reference to the drawings and examples.
Examples
As shown in fig. 1, the multi-wire rope segment blank of the utility model comprises a connecting part 1-1 for fixedly connecting with a wire rope, and one end of the connecting part is provided with a lifting lug 1-2 for connecting with a lifting appliance. Grooves 1-3 are formed in two corresponding side faces in the width or thickness direction of the connecting portion, and the grooves 1-3 are located in the middle of the side face of the connecting portion 1-1. The height AB of the groove 1-3 is 0.6 times greater than the height of the connecting part 1-1, the diameter of the steel wire rope is 10mm-20mm, the length of the connecting part 1-1 is 4-9 times of the diameter of the steel wire rope, the width AC of the groove 1-3 is 10-45mm, and the depth is 2-4.5mm. The groove is a V-shaped groove or an R-shaped groove.
In the embodiment, the grooves are V-shaped grooves, the number of steel wire ropes connected with the blank is 6, one end of each connecting part is uniformly distributed with 6 rope holes along the width direction of each connecting part, and when the steel wire ropes are pressed, one ends of the steel wire ropes are inserted into the corresponding rope holes in a one-to-one correspondence mode.
Comparative example 1
This comparative example was compared with the embodiment in which the height of the groove was 0.4 times the height of the connecting portion, and the other features were the same as the embodiment.
Comparative example 2
This comparative example has a groove width of 9mm compared to the example, and all other features are the same as the example.
Comparative example 3
This comparative example was compared to the examples, with a depth of 1.5mm, and the other features were the same as the examples.
Comparative example 4
The width of the groove was 50mm in this comparative example compared with the example, and the other features were the same as in the example.
Comparative example 5
This comparative example has a groove depth of 5mm compared to the example, and all other features are the same as the example.
The products of the manufacturing examples and comparative example 1 were produced using two identical sets of modules, respectively, the mold of comparative example 1 being produced with a significantly shorter service life than the mold of the manufacturing example.
The products of the manufacturing examples and comparative example 2 were produced using two identical sets of modules, respectively, the mold of comparative example 2 being produced with a significantly shorter life than the mold of the manufacturing example.
The products of the manufacturing examples and comparative example 3 were produced using two identical sets of modules, respectively, and the mold of comparative example 3 was produced with a significantly shorter life than the mold of the manufacturing example.
The strength test was carried out at the cost after lamination of comparative example 3 and example, and the tension after lamination of comparative example 3 was significantly smaller than the pressure after lamination of example.
The strength test was carried out at the cost after lamination of comparative example 4 and example, and the tension after lamination of comparative example 4 was significantly smaller than the pressure after lamination of example.
In summary, when the height, width and depth of the groove are smaller, the steel wire rope is more, the flowing amount of the material is large, the height, width and depth of the groove are small, the flowing requirement of the material cannot be met, and the die still has larger extrusion force, so that the die is easy to damage. When the height, width and depth of the groove are larger, after lamination, the flowing material cannot fill the groove, so that after lamination, the side surface of the finished product is still provided with an obvious groove, meanwhile, the steel wire rope is not firmly extruded, the quality problem is caused, the tensile force of the cost is lower, and the use requirement cannot be met.
