Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of wire rope production equipment, and in particular, to an end looping device for producing stainless steel wire ropes. Background Art

[0002] Wire rope is a spiral bundle of steel wires twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. It is composed of steel wires, a rope core and grease. The wire rope is first twisted into strands by multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. It is used for lifting, pulling, tensioning and carrying in material handling machinery. In addition, after the wire rope is prepared, it is usually necessary to use a U-shaped bayonet to connect it to the end.

[0003] Currently, a U-shaped clip is generally used to fix the end of the wire rope into a loop. However, when installing the U-shaped clip, the assembly is cumbersome, the structure is complex, and the stability is poor and it is easy to loosen and fall off. Another method is to directly cast a ring body at the end of the wire rope. However, when casting the existing wire rope, only a small part is placed into the casting body. The wire rope ring made by this casting method only has a small part of the wire rope involved in the casting, which means that the mechanical bite force between the casting material and the wire rope is weak. This not only affects the stability of the overall structure, but may also cause loosening or separation during use. Moreover, the existing method is not suitable for some thinner wire ropes. The main reason is that thin-diameter and particularly soft wire ropes are difficult to maintain their shape and position during the casting process and are prone to bending or displacement. This results in the casting material being unable to evenly wrap the wire rope, affecting the quality and strength of the final ring. Summary of the Invention

Then, with the cooperation of the lower mold groove 6 and the upper mold groove 12, the casting of the upper half is completed. This method solves the problem that only a small part of the wire rope is involved in the casting of the wire rope ring made by the existing casting method, so that the mechanical bite force between the casting material and the wire rope is weak; at the same time, it also solves the problem that the existing thin-diameter and particularly soft wire rope is difficult to maintain its shape and position during the casting process, and is prone to bending or displacement, resulting in the casting material being unable to evenly wrap the wire rope, affecting the quality and strength of the final ring.

One connecting pipe 162 is connected to the liquid supply port of the liquid supply device 161, and the other connecting pipe 162 is connected to the liquid return port of the liquid supply device 161; Its function is to work through the liquid supply device 161, and supply coolant to the interior of the lower liquid channel 163 and the T-shaped channel 165 on one side through the connecting pipe 162 on one side. The coolant will enter the interior of the lower cooling channel 164 and the upper cooling channel 166. At this time, the two control valves 168 are both open, and the coolant will enter the interior of the cooling chamber 132. The coolant in the lower cooling channel 164, the upper cooling channel 166, and the cooling chamber 132 will dissipate heat to the casting liquid. The coolant in the lower cooling channel 164 that takes away the heat of the casting liquid will enter the interior of the lower liquid channel 163 on the other side, and the coolant in the cooling chamber 132 that takes away the heat of the casting liquid will enter the C-shaped tube 167 and the T-shaped channel 165 on the other side. Finally, these two parts of coolant with heat will flow back to the interior of the liquid supply device 161 through the connecting pipe 162 on the other side until the casting liquid is cooled and formed, thereby speeding up the quality of the wire rope cast into rings.

[0032] Among them, the left parts of the lower die groove 6 and the upper die groove 12 are adapted to the die head 134, the left ends of the lower die groove 6 and the upper die groove 12 are adapted to the stainless steel wire rope, the upper surface of the module 11 is adapted to the lower die groove 6, the two C-shaped tubes 167 are clamped with the die head 134, the C-shaped tubes 167 are adapted to the channel formed by the lower die groove 6 and the upper die groove 12, and the grouting channel 15 and the interior of the through hole 133 are provided with a partition; Its function is to connect the existing gas supply device with the top of the grouting channel 15, shorten the small telescopic rod 10, and drive the module 11 to slide to the inside of the sliding groove 9, so that the lower mold groove 6 is connected with the exhaust channel 8, and the gas supply device supplies gas to the inside of the grouting channel 15, thereby cleaning the lower mold groove 6 and the lower surface of the mold body 131; similarly, by removing the middle mold 13, the surface of the upper mold groove 12 can be cleaned to prevent impurities from affecting the molding quality of the casting; and, atomized mold release agent can be supplied to the inside of the three to further improve the molding quality of the casting.

[0033] Working principle: The existing gas supply device is connected to the top of the grouting channel 15, and the small telescopic rod 10 is shortened, thereby driving the module 11 to slide to the inside of the sliding groove 9, so that the lower mold groove 6 is connected to the exhaust channel 8. The gas supply device supplies gas to the inside of the grouting channel 15, thereby cleaning the lower mold groove 6 and the lower surface of the mold body 131. Finally, the gas is discharged from the exhaust channel 8, and then the small telescopic rod 10 is extended to reset the module 11, and the casting liquid is cast into the interior of the lower mold groove 6 through the channel of half of the grouting channel 15, and the other half of the grouting channel 15 is used for exhaust until the casting liquid fills the space between the lower surface of the mold body 131 and the lower mold groove 6, and then the injection of casting liquid is stopped; at this time, the liquid supply device 161 works, and the liquid supply device 161 is connected to the lower surface of the mold body 131 through the connecting pipe 162 on one side.

The cooling liquid in the lower cooling channel 164 and the cooling cavity 132 dissipates heat from the casting liquid. The cooling liquid in the lower cooling channel 164 that takes away the heat of the casting liquid enters the interior of the lower liquid channel 163 on the other side, while the cooling liquid in the cooling cavity 132 that takes away the heat of the casting liquid enters the C-shaped tube 167 and the T-shaped channel 165 on the other side. Finally, these two parts of the cooling liquid with heat will flow back to the interior of the liquid supply device 161 through the connecting pipe 162 on the other side until the casting liquid is cooled and formed, and the control valve 168 is closed. The liquid supply device 161 stops working, the large telescopic rod 3 extends to separate the pressure cover 5 from the base 1, and then the middle mold 13 is removed. The C-shaped tube 167 will separate from the middle mold 13, and the stainless steel wire rope will be placed in the groove on the upper surface of the cooled and formed casting body. Then the large telescopic rod 3 shortens to close the pressure cover 5 and the module 11. The gas supply device cleans the upper surface of the casting body, the steel wire rope and the surface of the upper mold groove 12 by supplying gas to the inside of the grouting channel 15.

Then, the large telescopic rod 3 separates the pressure cover 5 from the base 1 by an appropriate distance, so that the steel wire rope is exposed at the left end of the lower mold groove 6. Then, half of the grouting channel 15 is used to inject casting liquid into the interior of the upper mold groove 12 until the interior of the upper mold groove 12 is filled. Then the liquid supply device 161 works to supply coolant to the interior of the lower cooling channel 164 and the upper cooling channel 166 until the casting wraps the steel wire rope into a ring.
