Abstract
The invention provides a double-compacted wire rope pressure-welded rigging. The double-compacted wire rope pressure-welded rigging is characterized in that the double-compacted wire rope pressure-welded rigging comprises a wire rope and a pressure-welded rigging sleeve. A bight is arranged on an end of the rope body of the wire rope. A connection part of the bight and the rope body is sealed and pressed in the pressure-welded rigging sleeve. The wire rope is a double-compacted wire rope with a broken pulling force coefficient higher than 0.46 and a strength grade higher than 2160MPA. The pressure-welded rigging sleeve is an endless annular steel sleeve manufactured through steps that: 1Cr17Ni steel is heated under a temperature of 1040 DEG C; the steel is subject to lead quenching; and the steel is subject to two times of tempering and forging under a temperature of 300-400 DEG C, such that the endless annular steel sleeve is obtained. The invention also provides a method for manufacturing the rigging. The strength of the double-compacted wire rope pressure-welded rigging manufactured with the method provided by the invention is consistent with the adopted double-compacted wire rope; the strength of the rigging is not influenced by the processing process. The bearing capacity of the rigging is improved by approximately 40% than a common pressed rigging.
Description
Technical field
The present invention relates to the rope technique field, relate in particular to a kind of pair of compacting steel rope crimping rigging and preparation method thereof.
Background technology
Current, rigging has been widely used in metallurgy, lifting transportation, construction trade, becomes indispensable lifting necessity.The load bearing stength of rigging is an important indicator of rigging; Present rigging on the market adopts the aluminum alloy sleeve pipe to contact steel rope with common round strand mostly and makes rigging; Its weight capacity is low, can't guarantee the safe reliability that lifts, can not satisfy the actual demand of using fully.
Summary of the invention
In view of this, be necessary to provide more powerful rigging of a kind of weight capacity and preparation method thereof.For this reason, the technical scheme of the present invention's employing is following:
A kind of pair of compacting steel rope crimping rigging is characterized in that comprise steel rope and crimping noose, the end of the rope body of steel rope is provided with fake, in said crimping noose is pressed in the linking part envelope of fake and rope body; Said steel rope is the two compacting steel ropes of rupture pull force coefficient more than 0.46, more than the strength grade 2160MPA; Said crimping noose is for using the 1Cr17Ni steel; Under 1040 ℃, the heating patenting is carried out double tempering again and is forged the electrodeless annular steel bushing that forms in 300-400 ℃.
The method for making of a kind of pair of compacting steel rope crimping rigging is characterized in that, may further comprise the steps:
(1) confirm specification: confirm the size of crimping noose and steel rope according to the specification demand of rigging, steel rope adopts the two compacting steel ropes of rupture pull force coefficient 0.46 or more, more than the strength grade 2160MPA;
(2) confirm mould: confirm the mould of crimping noose, use the Cr17Ni steel then, under 1040 ℃, double tempering is carried out in the heating patenting again in 300-400 ℃, forge into the crimping noose;
(3) compacting: the crimping noose is compressed on the fake of steel rope and the linking part of rope body.
Use the intensity of two compacting steel rope crimping riggings of the inventive method making to be consistent with the intensity of the two compacting steel ropes that adopted, the course of processing can not exert an influence to rigging intensity.The rigging load-carrying capacity has improved nearly 40% on the basis of common compacting rigging.
Description of drawings
Fig. 1 is the structural representation of of the present invention pair of compacting steel rope crimping rigging.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details.
A kind of pair of compacting steel rope crimping rigging as shown in Figure 1 comprises steel rope and crimping noose 3, and the end of the rope body 2 of steel rope is provided with fake 1, in said crimping noose 3 is pressed in the linking part envelope of fake 1 and rope body 2; Said steel rope is the two compacting steel ropes of rupture pull force coefficient more than 0.46, more than the strength grade 2160MPA; Said crimping noose 3 is for using the 1Cr17Ni steel; Under 1040 ℃, the heating patenting is carried out double tempering again and is forged the electrodeless annular steel bushing that forms in 300-400 ℃.
The method for making of said pair of compacting steel rope crimping rigging may further comprise the steps:
(1) confirms specification: the size of confirming crimping noose 3 according to the specification of rigging;
(2) confirm mould: confirm the mould of crimping noose 3, use the Cr17Ni steel then, under 1040 ℃, double tempering is carried out in the heating patenting again in 300-400 ℃, forge into crimping noose 3;
(3) compacting: crimping noose 3 is compressed on the fake 1 of steel rope and the linking part of rope body 2.
In the above-mentioned method for making, steel rope preferably adopts the two compacting steel ropes of rupture pull force coefficient more than 0.46, more than the strength grade 2160MPA.
Two compacting steel rope crimping rigging intensity of using said method to make can be consistent with the intensity of the two compacting steel ropes that adopted, and the course of processing can not exert an influence to rigging intensity.The rigging load-carrying capacity has improved nearly 40% on the basis of common compacting rigging.
The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
