Description

Technical Field

[0001] The invention relates to the technical field of suspension string production equipment, and in particular to an automatic processing system for suspension strings. Background Art

[0002] The railway overhead contact wire is one of the important components of the chain suspension. The contact wire is hung on the load-bearing cable through the wire. Adjusting the length of the wire can ensure the structural height of the contact suspension and the working height of the contact wire from the rail surface. In order to ensure the stability of the railway overhead contact power supply system, the processing quality of the wire is required to be high. The wire must be free of loose strands and broken strands. The length deviation of the wire should not exceed 1.5mm, and the head at the end of the wire should not be less than 50mm. The wire must be pre-tensioned to ensure that the wire remains in a stressed state, effectively avoiding deformation caused by the force on the wire, and meeting the high-precision requirements of the high-speed railway for the wire. How to accurately and efficiently complete the pre-assembly processing of the wire is of great significance.

[0003] At present, in the traditional railway electrical system construction, the suspension string is generally prepared by artificial prefabrication. The preparation of the suspension string requires the pre-assembly of the copper nose, heart-shaped ring and clamp tube at both ends of the suspension string, and the length of the suspension string needs to be precisely controlled.

[0004] It is difficult to ensure the accuracy of the heart-shaped wrapping system and the pre-assembly of the copper nose during manual operation, which will affect the precise control of the length of the suspension string. Moreover, during manual operation, it is also difficult to ensure the quality of the clamping process of the copper nose and the clamp-shaped tube, as well as the winding of the heart-shaped ring. More importantly, during manual operation, it is difficult to ensure the consistency of the pre-assembly quality of each suspension string. If such quality suspension strings are used for construction, the construction quality of the entire railway electrical system is difficult to guarantee, which is extremely easy to cause safety accidents. Finally, manual operation has low prefabrication efficiency, high labor intensity, extremely high scrap rate, and high overall cost. Summary of the invention

[0092] The crimping device also includes a crimping module 64 fixedly mounted on the device frame 61, and the crimping module 64 includes a crimping cylinder 6641 that provides power for crimping and a crimping die 642 fixedly mounted at the output end of the crimping cylinder 6641. The crimping cylinder 6641 drives the crimping die 642 to push out and press the joint of the copper nose with the suspension string.

[0093] The present invention also provides an improved technical solution, in which the crimping device further includes a blanking module 65 fixedly mounted on the device frame 61 and used to place the copper nose on the copper nose fixing fixture 632.

[0094] In this way, automatic unloading can be achieved, manual unloading can be avoided, efficiency can be improved, and labor can be reduced. At the same time, the safety of the device can be greatly improved, and the situation where the crimping module 64 crushes the hand during manual unloading can be avoided.

[0095] Preferably, the unloading module 65 of this solution can adopt the following structure: comprising a copper nose loading rack 655 vertically arranged on the top of the processing platform 62, the copper nose loading rack 655 is provided with a feed inlet 657 at the top and a discharge outlet at the bottom. The unloading module 65 also includes a placement mechanism for placing the copper nose in the copper nose loading rack 655 on the copper nose fixing fixture 632.

[0096] For example, an electromagnetic switch can be set at the discharge port as a placement mechanism to control the opening and closing time to ensure that a copper nose falls onto the copper nose fixing fixture 632 each time. A mechanical arm can also be used in conjunction with a clamp as a placement mechanism.

[0097] Preferably, the placement mechanism of the present scheme can adopt the following structure: it includes a loading and unloading control cylinder 651 and a lower loading and unloading cylinder 652 fixedly arranged on the side of the copper nose loading frame 655 and staggered, and the output ends of the loading and unloading control cylinder 651 and the lower loading and unloading cylinder 652 are respectively fixedly connected to the upper support plate 653 and the lower support plate 654.

[0098] The lower support plate 654 is located directly below the discharge port of the copper nose loading rack 655. It can close the discharge port when extended and open the discharge port when retracted.

[0099] The upper supporting plate 653 is located directly above the lower supporting plate 654 , and the distance between the upper supporting plate 653 and the lower supporting plate 654 is equal to the thickness of a copper nose.

[0100] The copper nose loading frame 655 is provided with a support plate insertion opening 658 for the upper support plate 653 and the lower support plate 654 to be inserted into. Specifically, this side of the copper nose loading frame 655 can be set to be open, and a limiting column 656 is set to prevent the copper nose from falling out. The upper support plate 653 and the lower support plate 654 can be inserted into the gap between the limiting columns 656.

[0101] The present invention also provides an improved technical solution, in which a blanking station 622 located below the copper nose loading rack 655 and a crimping station 623 located below the crimping mold 642 are provided in the jig limiting groove 621 .

[0102] Since the blanking module 65 and the crimping module 64 are provided, two workstations are required to complete the blanking and crimping.

[0103] Preferably, the jig module 63 includes a jig drive cylinder 631, the output end of which is fixedly connected to the copper nose fixing jig 632, and is used to drive the copper nose fixing jig 632 to move between the blanking station 622 and the crimping station 623. In this way, the copper nose fixing jig 632 can automatically switch between the two stations during the blanking and crimping process. The jig drive cylinder 631 can be assembled on the side of the device frame 61 using a fixed bracket 7.

[0104] Preferably, the jig module 63 also includes a positioning block 633 fixedly arranged at the tail of the jig limiting groove 621 for aligning the copper nose fixing jig 632 with the crimping station 623. This ensures that when the jig driving cylinder 631 pushes the copper nose fixing jig 632 to the crimping station 623, it can be accurately positioned.

[0105] In order to ensure stable operation, the fixture module 63 may further include a stable guide seat 635 installed at the head of the fixture limit groove 621. A guide hole is provided in the stable guide seat 635, and the piston rod of the fixture driving cylinder 631 is inserted into the guide hole.

[0106] Preferably, in order to ensure that the copper nose can be conveniently fixed on the copper nose fixing fixture 632, a fixing column 634 adapted to the opening of the copper nose can be provided on the copper nose fixing fixture 632.

[0107] The present invention also provides an improved technical solution. In the improved technical solution, the crimping device also includes a copper nose removal module 66 for removing the copper nose after crimping, including a pushing cylinder mechanism arranged at the bottom of the crimping station 623, which is used to push and impact the bottom of the crimping station 623 to pop the copper nose out of the station. The pushing cylinder mechanism is fixed to the bottom of the crimping station 623 through a fixing frame 664.

[0108] After crimping is completed, the copper nose needs to be taken out for the next crimping operation. Due to the existence of the jig, the entire device structure is relatively compact, and the manual removal efficiency is too low, so the present invention adopts a push and impact method, using the impact force to make the copper nose pop out of the copper nose fixing jig 632, and at the same time, the jig driving cylinder 631 retracts the copper nose fixing jig 632 to the unloading station 622, so that it can be automatically removed.

[0109] In order to ensure that the impact force is moderate and avoid damage to the device, the push cylinder mechanism of the present invention preferably adopts the following structure: it includes an adsorption cylinder 661, the piston rod 662 of the adsorption cylinder 661 extends into the fixed frame 664, and a push block 663 is fixedly installed at the end of the piston rod 662. A spring 665 is arranged between the push block 663 and the fixed frame 664 to provide power so that the push block 663 hits the bottom of the crimping station 623.

[0110] In order to ensure the accuracy of operation, the push cylinder mechanism may further include a guide column 666. The guide column 666 may be arranged at the bottom of the fixing frame 664 and has a guide hole therein for passing the piston rod 662.

[0111] The working principle of the present invention is as follows:

[0112] Wire feeding:

[0113] First, the suspension string 59 is fed into the return line guide block 522 of the heart-shaped ring forming device 5 fixed on the head of the machine body 1 through the suspension string cutting device 2, and then sent out after passing through the heart-shaped ring forming device 5, and then sent to the heart-shaped ring forming device 5 of the wire pulling device 7 through the wire feeding mechanism 9.

[0114] Heart-shaped ring and clamp-shaped tube winding processing:

[0115] When the device is processed, the clamp tube is first placed in the clamping position through the clamp tube feeding mechanism 32, the telescopic wedge 532 is extended, the wedge 5320 is pushed between the two clamping molds 5311 of the clamping assembly 531, the clamping cylinder 5310 is started, the clamping mold 5311 is pushed to clamp the clamp tube and fix it, and the pre-clamping of the clamp tube is completed.

[0116] After pre-compression is completed, the suspension string 59 is fed in through the wire feeding channel 523 of the wire feeding groove 52. When the suspension string 59 is fed in, the telescopic cover mechanism 58 is started, and the cover 582 seals the top of the wire feeding channel 523 to prevent the suspension string 59 from falling out.

[0117] After the hanging string 59 is fed into the wire feeding groove 52, the heart-shaped ring is placed at the corresponding position of the fixed workbench 57, the heart-shaped ring locking mechanism 56 is started, the lifting cylinder 563 pushes the heart-shaped ring positioning block 562 to rise, and the heart-shaped ring positioning block 562 penetrates into the heart-shaped ring to fix the heart-shaped ring.

[0118] After the heart-shaped ring is fixed, the wire is continuously fed, and the suspension string 59 passes through the clamp tube and enters the fixed workbench 57. At this time, the heart-shaped ring pressing mechanism 54 is started, and the lifting cylinder 543 retracts the lifting column 544, and pulls the pressing workbench 541 back to the fixed workbench 57. Then the push cylinder 5422 pulls the guide slider 5421 back along the sliding limit plate 5420, and the forming motor 5424 is started to drive the forming wheel 5423 to rotate, guiding the fed suspension string 59 to move around the heart-shaped ring in a circular direction. After the suspension string 59 runs half a circle, the pressing guide mechanism 55 is started, and the driving cylinder pushes out the guide plate to limit the running direction of the suspension string 59. At this time, the push cylinder 5422 pushes the guide slider 5421 along the sliding limit plate 5420, and cooperates with the guide plate to allow the suspension string 59 to continue to move around the heart-shaped ring in a circular direction until the suspension string 59 passes through the clamp tube in the reverse direction and enters the wire groove of the return wire guide block 522, and the winding process is completed.

[0119] Copper nose crimping:

[0120] First, use the unloading module 65 to unload. Load the copper nose into the copper nose loading rack 655 from the feed port 657. At this time, the unloading control cylinder 652 is in the push-out state, and the loading and unloading control cylinder 651 is in the retracted state. When unloading, the loading and unloading control cylinder 651 is pushed out, and the upper support plate 653 extends into the copper nose loading rack 655 to support the copper noses except the bottom copper nose in the copper nose loading rack 655; and the unloading control cylinder 652 is retracted, and the lower support plate 654 is pulled out from the copper nose loading rack 655. At this time, the bottom copper nose loses its support and falls under the action of gravity, falling into the copper nose fixing fixture 632 located at the bottom of the copper nose loading rack 655, completing the unloading. After unloading is completed, the unloading control cylinder 652 is pushed out, the lower support plate 654 closes the discharge port, and the unloading control cylinder 651 is retracted, the upper support plate 653 is withdrawn, and restored to the initial state, waiting for the next unloading.

[0121] After unloading, the jig driving cylinder 631 is started to push out the copper nose fixing jig 632 until it stops at the positioning block 633. At this time, the copper nose fixing jig 632 is accurately moved to the crimping station 623.

[0122] After the copper nose fixing fixture 632 is accurately moved to the crimping station 623, the suspension string 59 is inserted into the copper nose through the wire feeding mechanism 9. Then the crimping module 64 is started, and the crimping cylinder 641 drives the crimping die 642 to push out, and the copper nose with the suspension string inserted is pressed tightly to complete the crimping.

[0123] After the crimping is completed, the copper nose disengagement module 66 is started, the adsorption cylinder 661 is released, the air suction stops, the piston rod 662 loses adsorption, and the top block 663 is driven by the rebound force of the spring 665 to quickly bounce upward and hit the bottom of the crimping station 623. After the impact, the copper nose bounces up and breaks away from the copper nose fixing fixture 632. At the same time, the fixture driving cylinder 631 is started to retract the copper nose fixing fixture 632 to the unloading station 622. The entire crimping process is completed, and the entire device returns to its initial state.

[0124] Pull Wire:

[0125] After the copper nose crimping process is completed, the string locking mechanism 510 is started to lock and fix the string 59. Then the lifting cylinder 543 of the heart-shaped ring pressing mechanism 54 raises the lifting column 544, lifts the pressing workbench 541, and lifts it away from the fixed workbench 57, while the driving cylinder of the pressing guide mechanism 55 retracts the guide plate at the same time. Then the wire feeding mechanism 9 is disengaged, and the wire pulling device 7 is started. The wire pulling device 7 moves horizontally to drive the heart-shaped ring forming device 5 installed on the wire pulling device to move, and the string 59 is pulled until the string 59 reaches the specified length and stops, and the string cutting device 2 cuts the string 59.

[0126] Processing of heart-shaped ring and clamp-shaped tube:

[0127] When the suspension string 59 is in a taut state, retract the telescopic wedge 532, start the clamping assembly 531 again, and the clamping cylinder 5310 pushes the clamping mold 5311 to clamp the clamp tube. After clamping, the clamping cylinder 5310 is retracted, the suspension string locking mechanism 510 releases the suspension string 59, and the telescopic cover mechanism 58 is also retracted to take out the suspension string 59, thereby completing the processing of the heart-shaped ring and the clamp tube.

[0128] The working process of the present invention is that the suspension string 59 is first fed in by the return wire guide block 522 of the heart-shaped ring forming device 5 fixed on the head of the machine body 1, and then passed out in the reverse direction and sent to the heart-shaped ring forming device 5 of the wire drawing device 7, so as to complete the crimping of the copper nose and the winding of the heart-shaped ring on one side of the wire drawing device 7 and the pre-tightening of the clamp-shaped tube. Then the suspension string 59 on one side of the wire drawing device 7 is locked, and the wire drawing device 7 is pulled horizontally as a whole to cut the wire to the specified length. After cutting the wire, the wire drawing device 7 moves in the reverse direction, and the wire feeding mechanism 9 of the heart-shaped ring forming device 5 on the head of the machine body 1 feeds the wire, and the cut suspension string 59 is sent to the copper nose crimping device 6 on the head of the machine body 1 to complete the crimping of the copper nose. Finally, the suspension string 59 on the head of the machine body 1 is locked, and the wire drawing device 7 is translated again to tighten the suspension string 59 in a taut state, and the heart-shaped ring forming devices 5 on both sides complete the compression of the clamp-shaped tube, and the suspension string 59 is released, and the processing of the entire suspension string 59 is completed.
